SECTION .0300 ‑ AIR POLLUTION EMERGENCIES

 

15A NCAC 02D .0301       PURPOSE

Notwithstanding any other provisions of air pollution control regulations or standards, this Section is designed to prevent the excessive buildup of air contaminants during air pollution episodes thereby preventing the occurrence of an emergency due to the effects of these contaminants on the public health.

 

History Note:        Authority G.S. 143‑215.3(a)(1); 143‑215.3(a)(12);

Eff. February 1, 1976.

 

15A NCAC 02D .0302       EPISODE CRITERIA

Conditions justifying the proclamation of an air pollution alert, air pollution warning, or air pollution emergency shall be deemed to exist whenever the director determines that the accumulation of air contaminants in any place is attaining or has attained levels that could, if such levels are sustained or exceeded, lead to a threat to the health of the public.  In making this determination, the director shall be guided by the following criteria:

(1)           Air Pollution Forecast.  An internal watch by the Division and local air pollution control agencies shall be activated by a National Weather Service advisory that an atmospheric stagnation advisory is in effect, or the equivalent local forecast of stagnant atmospheric conditions.

(2)           Alert.  The alert level is that concentration of pollutants at which first stage control actions are to begin.  The director shall proclaim an alert when any of the following levels is reached at any monitoring site:

(a)           sulfur dioxide -- 800 ug/m3 (0.3 p.p.m.), 24-hour average;

(b)           particulate -- 375 ug/m3, 24-hour average;

(c)           sulfur dioxide and particulate combined -- product of sulfur dioxide ug/m3, 24-hour average, and particulate ug/m3, 24-hour average, equal to 65,000;

(d)           carbon monoxide  --  17 mg/m3 (15 p.p.m.), eight-hour average;

(e)           ozone -- 400 ug/m3 (0.2 p.p.m.), one-hour average;

(f)            nitrogen dioxide  -- 1130 ug/m3 (0.6 p.p.m.), one-hour average; 282 ug/m3 (0.15 p.p.m.), 24-hour average;

(g)           PM10--350 ug/m;, 24-hour average;and meteorological conditions are such that pollutant concentrations can be expected to remain at these levels for 12 or more hours or increase or, for ozone, the situation is likely to recur within the next 24-hours unless control actions are taken.

(3)           Warning.  The warning level indicates that air quality is continuing to degrade and that additional abatement actions  are necessary.  The Director shall proclaim a warning when any one of the following levels is reached at any monitoring site:

(a)           sulfur dioxide  --  1600 ug/m3 (0.6 p.p.m.), 24-hour average

(b)           particulate -- 625 ug/m3, 24-hour average;

(c)           sulfur dioxide and particulate combined -- product of sulfur dioxide ug/m3, 24-hour average, and particulate ug/m3, 24-hour average, equal to 261,000;

(d)           carbon monoxide  --  34 mg/m3 (30 p.p.m.), eight-hour average;

(e)           ozone -- 800 ug/m3 (0.4 p.p.m.), one-hour average;

(f)            nitrogen dioxide  --  2260 ug/m3 (1.2 p.p.m.), one-hour average; 565 ug/m3 (0.3 p.p.m.), 24-hour average;

(g)           PM10  --  420 ug/m;; 24-hour average;and meteorological conditions are such that pollutant concentrations can be expected to remain at these levels for 12 or more hours or increase or, for ozone, the situation is likely to recur within the next 24 hours unless control actions are taken.

(4)           Emergency.  The emergency level indicates that air quality is continuing to degrade to a level that should never be reached and that the most stringent control actions are necessary.  The Secretary of the Department of Environment and Natural Resources with the concurrence of the Governor shall declare an emergency when any one of the following levels is reached at any monitoring site:

(a)           sulfur dioxide  --  2100 ug/m3 (0.8 p.p.m.), 24-hour average;

(b)           particulate -- 875 ug/m3, 24-hour average;

(c)           sulfur dioxide and particulate combined -- product of sulfur dioxide ug/m3, 24-hour average, and particulate ug/m3, 24-hour average, equal to 393,000;

(d)           carbon monoxide  --  46 mg/m3 (40 p.p.m.), eight-hour average;

(e)           ozone -- 1000 ug/m3 (0.5 p.p.m.), one-hour average;

(f)            nitrogen dioxide  -- 3000 ug/m3 (1.6 p.p.m.), one-hour average; 750 ug/m3 (0.4 p.p.m.), 24-hour average;

(g)           PM10--500 ug/m;, 24-hour average.

(5)           Termination.  Once declared any level reached by application of these criteria shall remain in effect until the criteria for that level are no longer met.  At that time the next lower level shall be assumed.

SECTION .0400 ‑ AMBIENT AIR QUALITY STANDARDS

 

15A NCAC 02D .0401       PURPOSE

(a)  The purpose of the ambient air quality standards set out in this Section is to establish certain maximum limits on parameters of air quality considered desirable for the preservation and enhancement of the quality of the state's air resources.  Furthermore, the objective of the Commission, consistent with the North Carolina Air Pollution Control Law, shall be to prevent significant deterioration in ambient air quality in any substantial portion of the state where existing air quality is better than the standards.  An atmosphere in which these standards are not exceeded should provide for the protection of the public health, plant and animal life, and property.

(b)  Ground level concentrations of pollutants will be determined by sampling at fixed locations in areas beyond the premises on which a source is located.  The standards are applicable at each such sampling location in the state.

(c)  No facility or source of air pollution shall cause any ambient air quality standard in this Section to be exceeded or contribute to a violation of any ambient air quality standard in this Section except as allowed by Rules .0531 or .0532 of this Subchapter.

SECTION .0500 ‑ EMISSION CONTROL STANDARDS

 

15A NCAC 02D .0501       COMPLIANCE WITH EMISSION CONTROL STANDARDS

(a)  Purpose and Scope. The purpose of this Rule is to assure orderly compliance with emission control standards found in this Section. This Rule shall apply to all air pollution sources, both combustion and non‑combustion.

(b)  All new sources shall be in compliance prior to beginning operations.

(c)  In addition to any control or manner of operation necessary to meet emission standards in this Section, any source of air pollution shall be operated with such control or in such manner that the source shall not cause the ambient air quality standards of Section .0400 of this Subchapter to be exceeded at any point beyond the premises on which the source is located.  When controls more stringent than named in the applicable emission standards in this Section are required to prevent violation of the ambient air quality standards or are required to create an offset, the permit shall contain a condition requiring these controls.

(d)  The Bubble Concept. A facility with multiple emission sources or multiple facilities within the same area may choose to meet the total emission limitation for a given pollutant through a different mix of controls than that required by the rules in this Section or Section .0900 of this Subchapter.

(1)           In order for this mix of alternative controls to be permitted the Director shall determine that the following conditions are met:

(A)          Sources to which Rules .0524, .0530, .0531, .1110 or .1111 of this Subchapter, the federal New Source Performance Standards (NSPS), the federal National Emission Standards for Hazardous Air Pollutants (NESHAPS), regulations established pursuant to Section 111 (d) of the federal Clean Air Act, or state or federal Prevention of Significant Deterioration (PSD) requirements apply, shall have emissions no larger than if there were not an alternative mix of controls;

(B)          The facility (or facilities) is located in an attainment area or an unclassified area or in an area that has been demonstrated to be attainment by the statutory deadlines (with reasonable further progress toward attainment) for those pollutants being considered;

(C)          All of the emission sources affected by the alternative mix are in compliance with applicable regulations or are in compliance with established compliance agreements; and

(D)          The review of an application for the proposed mix of alternative controls and the enforcement of any resulting permit will not require expenditures on the part of the State in excess of five times that which would otherwise be required.

(2)           The owner(s) or operator(s) of the facility (facilities) shall demonstrate to the satisfaction of the Director that the alternative mix of controls is equivalent in total allowed emissions, reliability, enforceability, and environmental impact to the aggregate of the otherwise applicable individual emission standards; and

(A)          that the alternative mix approach does not interfere with attainment and maintenance of ambient air quality standards and does not interfere with the PSD program; this demonstration shall include modeled calculations of the amount, if any, of PSD increment consumed or created;

(B)          that the alternative mix approach conforms with reasonable further progress requirements in any nonattainment area;

(C)          that the emissions under the alternative mix approach are in fact quantifiable, and trades among them are even;

(D)          that the pollutants controlled under the alternative mix approach are of the same criteria pollutant categories, except that emissions of some criteria pollutants used in alternative emission control strategies are subject to the limitations as defined in 44 FR 71784 (December 11, 1979), Subdivision D.1.c.ii. The Federal Register referenced in this Part is hereby incorporated by reference and does not include subsequent amendments or editions.

The demonstrations of equivalence shall be performed with at least the same level of detail as The North Carolina State Implementation Plan for Air Quality demonstration of attainment for the area in question. Moreover, if the facility involves another facility in the alternative strategy, it shall complete a modeling demonstration to ensure that air quality is protected. Demonstrations of equivalency shall also take into account differences in the level of reliability of the control measures or other uncertainties.

(3)           The emission rate limitations or control techniques of each source within the facility (facilities) subjected to the alternative mix of controls shall be specified in the facility's (facilities') permits(s).

(4)           Compliance schedules and enforcement actions shall not be affected because an application for an alternative mix of controls is being prepared or is being reviewed.

(5)           The Director may waive or reduce requirements in this Paragraph up to the extent allowed by the Emissions Trading Policy Statement published in the Federal Register of April 7, 1982, pages 15076‑15086, provided that the analysis required by Paragraph (e) of this Rule supports any waiver or reduction of requirements. The Federal Register referenced in this Paragraph is hereby incorporated by reference and does not include subsequent amendments or editions.

(e)  In a permit application for an alternative mix of controls under Paragraph (d) of this Rule, the owner or operator of the facility shall demonstrate to the satisfaction of the Director that the proposal is equivalent to the existing requirements of the SIP in total allowed emissions, enforceability, reliability, and environmental impact. The Director shall provide for public notice with an opportunity for a request for public hearing following the procedures under 15A NCAC 02Q .0300 or .0500, as applicable.

(1)           If and when a permit containing these conditions is issued under 15A NCAC 02Q .0300 (non-Title V permits), it shall become a part of the state implementation plan (SIP) as an appendix available for inspection at the department's regional offices. Until the U.S. Environmental Protection Agency (EPA) approves the SIP revision embodying the permit containing an alternative mix of controls, the facility shall continue to meet the otherwise applicable existing SIP requirements.

(2)           If and when a permit containing these conditions is issued under 15A NCAC 02Q .0500 (Title V permits), it shall be available for inspection at the department's regional offices. Until the EPA approves the Title V permit containing an alternative mix of controls, the facility shall continue to meet the otherwise applicable existing SIP requirements.

The revision shall be approved by EPA on the basis of the revision's consistency with EPA's "Policy for Alternative Emission Reduction Options Within State Implementation Plans" as promulgated in the Federal Register of December 11, 1989, pages 71780‑71788, and subsequent rulings.

If owner or operator of any combustion and non‑combustion source or control equipment subject to the requirements of this Section is required to demonstrate compliance with a rule in this Section, the source testing procedures of Section .2600 of this Subchapter shall be used.

15A NCAC 02D .0503       PARTICULATES FROM FUEL BURNING INDIRECT HEAT EXCHANGERS

(a)  For the purpose of this Rule the following definitions shall apply:

(1)           "Functionally dependent" means that structures, buildings or equipment are interconnected through common process streams, supply lines, flues, or stacks.

(2)           "Indirect heat exchanger" means any equipment used for the alteration of the temperature of one fluid by the use of another fluid in which the two fluids are separated by an impervious surface such that there is no mixing of the two fluids.

(3)           "Plant site" means any single or collection of structures, buildings, facilities, equipment, installations, or operations which:

(A)          are located on one or more adjacent properties,

(B)          are under common legal control, and

(C)          are functionally dependent in their operations.

(b)  The definition contained in Subparagraph (a)(3) of this Rule does not affect the calculation of the allowable emission rate of any indirect heat exchanger permitted prior to April 1, 1999.

(c)  With the exceptions in Rule .0536 of this Section, emissions of particulate matter from the combustion of a fuel that are discharged from any stack or chimney into the atmosphere shall not exceed:

 

Allowable Emission Limit

Maximum Heat Input In                                                                   For Particulate Matter

Million Btu/Hour                                                                                 In Lb/Million Btu

 


Up to and Including 10                                                                                      0.60

100                                                                                                                         0.33

1,000                                                                                                                      0.18

10,000 and Greater                                                                                             0.10

 

For a heat input between any two consecutive heat inputs stated in the preceding table, the allowable emissions of particulate matter shall be calculated by the equation E = 1.090 times Q to the ‑0.2594 power.  E = allowable emission limit for particulate matter in lb/million Btu.  Q = maximum heat input in million Btu/hour.

(d)  This Rule applies to installations in which fuel is burned for the purpose of producing heat or power by indirect heat transfer.  Fuels include those such as coal, coke, lignite, peat, natural gas, and fuel oils, but exclude wood and refuse not burned as a fuel.  When any refuse, products, or by‑products of a manufacturing process are burned as a fuel rather than refuse, or in conjunction with any fuel, this allowable emission limit shall apply.

(e)  For the purpose of this Rule, the maximum heat input shall be the total heat content of all fuels which are burned in a fuel burning indirect heat exchanger, of which the combustion products are emitted through a stack or stacks.  The sum of maximum heat input of all fuel burning indirect heat exchangers at a plant site which are in operation, under construction, or permitted pursuant to 15A NCAC 2Q, shall be considered as the total heat input for the purpose of determining the allowable emission limit for particulate matter for each fuel burning indirect heat exchanger.  Fuel burning indirect heat exchangers constructed or permitted after February 1, 1983, shall not change the allowable emission limit of any fuel burning indirect heat exchanger whose allowable emission limit has previously been set.  The removal of a fuel burning indirect heat exchanger shall not change the allowable emission limit of any fuel burning indirect heat exchanger whose allowable emission limit has previously been established.  However, for any fuel burning indirect heat exchanger constructed after, or in conjunction with, the removal of another fuel burning indirect heat exchanger at the plant site, the maximum heat input of the removed fuel burning indirect heat exchanger shall no longer be considered in the determination of the allowable emission limit of any fuel burning indirect heat exchanger constructed after or in conjunction with the removal.  For the purposes of this Paragraph, refuse not burned as a fuel and wood shall not be considered a fuel.  For residential facilities or institutions (such as military and educational) whose primary fuel burning capacity is for comfort heat, only those fuel burning indirect heat exchangers located in the same power plant or building or otherwise physically interconnected (such as common flues, steam, or power distribution line) shall be used to determine the total heat input.

(f)  The emission limit for fuel burning equipment that burns both wood and other fuels in combination, or for wood and other fuel burning equipment that is operated such that emissions are measured on a combined basis, shall be calculated by the equation Ec = [(EW)(Qw) + (Eo)(Qo)] /Qt.

(1)           Ec = the emission limit for combination or combined emission source(s) in lb/million Btu.

(2)           Ew = plant site emission limit for wood only as determined by Rule .0504 of this Section in lb/million  Btu.

(3)           Eo = the plant site emission limit for other fuels only as determined by Paragraphs (a), (b) and (c) of this Rule in lb/million Btu.

(4)           Qw = the actual wood heat input to the combination or combined emission source(s) in Btu/hr.

(5)           Qo = the actual other fuels heat input to the combination or combined emission source(s) in Btu/hr.

(6)           Qt = Qw + Qo and is the actual total heat input to combination or combined emission source(s) in  Btu/hr.

10,000 and Greater                                                                                             0.15

 

For a heat input between any two consecutive heat inputs stated in the preceding table, the allowable emissions of particulate matter shall be calculated by the equation E = 1.1698 (Q to the -0.2230 power.)  E = allowable emission limit for particulate matter in lb/million Btu. Q = Maximum heat input in million Btu/hour.

(d)  This Rule applies to installations in which wood is burned for the primary purpose of producing heat or power by indirect heat transfer.

(e)  For the purpose of this Rule, the heat content of wood shall be 8,000 Btu per pound (dry-weight basis). The total of maximum heat inputs of all wood burning indirect heat exchangers at a plant site in operation, under construction, or with a permit shall be used to determine the allowable emission limit of a wood burning indirect heat exchanger. Wood burning indirect heat exchangers constructed or permitted after February 1, 1983, shall not change the allowable emission limit of any wood burning indirect heat exchanger whose allowable emission limit has previously been set.

(f)  The emission limit for fuel burning equipment that burns both wood and other fuels in combination or for wood and other fuel burning equipment that is operated such that emissions are measured on a combination basis shall be calculated by the procedure described in Paragraph (f) of Rule .0503 of this Section.

15A NCAC 02D .0521       CONTROL OF VISIBLE EMISSIONS

(a)  Purpose. The intent of this Rule is to prevent, abate and control emissions generated from fuel burning operations and industrial processes where an emission can reasonably be expected to occur, except during startup, shutdowns, and malfunctions approved according to procedures set out in Rule .0535 of this Section.

(b)  Scope. This Rule shall apply to all fuel burning sources and to other processes that may have a visible emission. However, sources subject to a visible emission standard in Rules .0506, .0508, .0524, .0543, .0544, .1110, .1111, .1205, .1206, .1210, .1211, or .1212 of this Subchapter shall meet that standard instead of the standard contained in this Rule. This Rule does not apply to engine maintenance, rebuild, and testing activities where controls are infeasible, except it does apply to the testing of peak shaving and emergency generators.  (In deciding if controls are infeasible, the Director shall consider emissions, capital cost of compliance, annual incremental compliance cost, and environmental and health impacts.)

(c)  For sources manufactured as of July 1, 1971, visible emissions shall not be more than 40 percent opacity when averaged over a six-minute period. However, except for sources required to comply with Paragraph (g) of this Rule, six-minute averaging periods may exceed 40 percent opacity if:

(1)           No six-minute period exceeds 90 percent opacity;

(2)           No more than one six-minute period exceeds 40 percent opacity in any hour; and

(3)           No more than four six-minute periods exceed 40 percent opacity in any 24-hour period.

(d)  For sources manufactured after July 1, 1971, visible emissions shall not be more than 20 percent opacity when averaged over a six-minute period. However, except for sources required to comply with Paragraph (g) of this Rule, six-minute averaging periods may exceed 20 percent opacity if:

(1)           No six-minute period exceeds 87 percent opacity;

(2)           No more than one six-minute period exceeds 20 percent opacity in any hour; and

(3)           No more than four six-minute periods exceed 20 percent opacity in any 24-hour period.

(e)  Where the presence of uncombined water is the only reason for failure of an emission to meet the limitations of Paragraph (c) or (d) of this Rule, those requirements shall not apply.

(f)  Exception from Opacity Standard in Paragraph (d) of this Rule. Sources subject to Paragraph (d) of this Rule shall be allowed to comply with Paragraph (c) of this Rule if:

(1)           The owner or operator of the source demonstrates compliance with applicable particulate mass emissions standards; and

(2)           The owner or operator of the source submits data necessary to show that emissions up to those allowed by Paragraph (c) of this Rule shall not violate any national ambient air quality standard.

The burden of proving these conditions shall be on the owner or operator of the source and shall be approached in the following manner.  The owner or operator of a source seeking an exception shall apply to the Director requesting this modification in its permit.  The applicant shall submit the results of a source test within 90 days of application. Source testing shall be by the appropriate procedure as designated by rules in this Subchapter. During this 90-day period the applicant shall submit data necessary to show that emissions up to those allowed by Paragraph (c) of this Rule will not contravene ambient air quality standards.  This evidence shall include an inventory of past and projected emissions from the facility.  In its review of ambient air quality, the Division may require additional information that it considers necessary to assess the resulting ambient air quality.  If the applicant can thus show that it will be in compliance both with particulate mass emissions standards and ambient air quality standards, the Director shall modify the permit to allow emissions up to those allowed by Paragraph (c) of this Rule.

(g)  For sources required to install, operate, and maintain continuous opacity monitoring systems (COMS), compliance with the numerical opacity limits in this Rule shall be determined as follows excluding startups, shutdowns, maintenance periods when fuel is not being combusted, and malfunctions approved as such according to procedures approved under Rule .0535 of this Section:

(1)           No more than four six-minute periods shall exceed the opacity standard in any one day; and

(2)           The percent of excess emissions (defined as the percentage of monitored operating time in a calendar quarter above the opacity limit) shall not exceed 0.8 percent of the total operating hours. If a source operates less than 500 hours during a calendar quarter, the percent of excess emissions shall be calculated by including hours operated immediately previous to this quarter until 500 operational hours are obtained.

In no instance shall excess emissions exempted under this Paragraph cause or contribute to a violation of any emission standard in this Subchapter or 40 CFR Part 60, 61, or 63 or any ambient air quality standard in Section 15A NCAC 02D .0400 or 40 CFR Part 50.

15A NCAC 02D .0530       PREVENTION OF SIGNIFICANT DETERIORATION

(a)  The purpose of the Rule is to implement a program for the prevention of significant deterioration of air quality as required by 40 CFR 51.166.

(b)  For the purposes of this Rule, the definitions contained in 40 CFR 51.166(b) and 40 CFR 51.301 apply, except the definition of "baseline actual emissions." For the purposes of this Rule:

(1)           "Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated new source review (NSR) pollutant, as determined in accordance with Parts (A) through (C) of this Subparagraph:

(A)          For an existing emissions unit, baseline actual emissions means the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during any consecutive 24-month period selected by the owner or operator within the five year period immediately preceding the date that a complete permit application is received by the Division for a permit required under this Rule. The Director shall allow a different time period, not to exceed 10 years immediately preceding the date that a complete permit application is received by the Division, if the owner or operator demonstrates that it is more representative of normal source operation. For the purpose of determining baseline actual emissions, the following apply:

(i)            The average rate shall include fugitive emissions to the extent quantifiable and emissions associated with startups, shutdowns, and malfunctions;

(ii)           The average rate shall be adjusted downward to exclude any non-compliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive 24-month period;

(iii)          For an existing emission unit (other than an electric utility steam generating unit), the average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source must currently comply. However, if the State has taken credit in an attainment demonstration or maintenance plan consistent with the requirements of 40 CFR 51.165(a)(3)(ii)(G) for an emission limitation that is part of a maximum achievable control technology standard that the Administrator proposed or promulgated under Part 63 in Title 40 of the Code of Federal Regulations, the baseline actual emissions shall be adjusted to account for such emission reductions;

(iv)          For an electric utility steam generating unit, the average rate shall be adjusted downward to reflect any emissions reductions under G.S. 143-215.107D and for which cost recovery is sought pursuant to G.S. 62-133.6;

(v)           For a regulated NSR pollutant, if a project involves multiple emissions units, only one consecutive 24-month period shall be used to determine the baseline actual emissions for all the emissions units being changed. A different consecutive 24-month period for each regulated NSR pollutant may be used for each regulated NSR pollutant; and

(vi)          The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by Subparts (ii) and (iii) of this Part;

(B)          For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of such unit shall equal zero and thereafter, for all other purposes, shall equal the unit's potential to emit; and

(C)          For a plantwide applicability limit (PAL) for a stationary source, the baseline actual emissions shall be calculated for existing emissions units in accordance with the procedures contained in Part (A) of this Subparagraph and, for a new emissions unit, in accordance with the procedures contained in Part (B) of this Subparagraph;

(2)           In the definition of "net emissions increase," the reasonable period specified in 40 CFR 51.166(b)(3)(ii) shall be seven years;

(3)           The limitation specified in 40 CFR 51.166(b)(15)(ii) shall not apply; and

(4)           Particulate matter PM2.5 significant levels set forth in 40 CFR 51.166(b)(23)(i) are incorporated by reference except as otherwise provided in this Rule. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are precursors to PM2.5 in all attainment and unclassifiable areas. Volatile organic compounds and ammonia are not significant precursors to PM2.5.

(c)  All areas of the State are classified as Class II, except the following areas, which are designated as Class I:

(1)           Great Smoky Mountains National Park;

(2)           Joyce Kilmer Slickrock National Wilderness Area;

(3)           Linville Gorge National Wilderness Area;

(4)           Shining Rock National Wilderness Area; and

(5)           Swanquarter National Wilderness Area.

(d)  Redesignations of areas to Class I or II may be submitted as state proposals to the Administrator of the Environmental Protection Agency (EPA) if the requirements of 40 CFR 51.166(g)(2) are met. Areas may be proposed to be redesignated as Class III if the requirements of 40 CFR 51.166(g)(3) are met. Redesignations may not, however, be proposed which would violate the restrictions of 40 CFR 51.166(e). Lands within the boundaries of Indian Reservations may be redesignated only by the appropriate Indian Governing Body.

(e)  In areas designated as Class I, II, or III, increases in pollutant concentration over the baseline concentration shall be limited to the values set forth in 40 CFR 51.166(c). However, concentration of the pollutant shall not exceed standards set forth in 40 CFR 51.166(d).

(f)  Concentrations attributable to the conditions described in 40 CFR 51.166(f)(1) shall be excluded in determining compliance with a maximum allowable increase. However, the exclusions referred to in 40 CFR 51.166(f)(1)(i) or (ii) shall be limited to five years as described in 40 CFR 51.166(f)(2).

(g)  Major stationary sources and major modifications shall comply with the requirements contained in 40 CFR 51.166 (a)(7) and (i) and in 40 CFR 51.166(j) through (o) and (w). The transition provisions allowed by 40 CFR 52.21(i)(11)(i) and (ii) and (m)(1)(vii) and (viii) are hereby adopted under this Rule. The minimum requirements described in the portions of 40 CFR 51.166 referenced in this Paragraph are hereby adopted as requirements under this Rule, except as otherwise provided in this Rule. Wherever the language of the portions of 40 CFR 51.166 referenced in this Paragraph speaks of the "plan," the requirements described therein shall apply to the source to which they pertain, except as otherwise provided in this Rule. Whenever the portions of 40 CFR 51.166 referenced in this Paragraph provide that the State plan may exempt or not apply certain requirements in certain circumstances, those exemptions and provisions of nonapplicability are also hereby adopted under this Rule. However, this provision shall not be interpreted so as to limit information that may be requested from the owner or operator by the Director as specified in 40 CFR 51.166(n)(2).

(h)  New natural gas-fired electrical utility generating units for which cost recovery is sought pursuant to G.S. 62-133.6 shall install best available control technology for NOX and SO2, regardless of the applicability of the rest of this Rule.

(i)  For the purposes of this Rule, 40 CFR 51.166(w)(10)(iv)(a) shall read: "If the emissions level calculated in accordance with Paragraph (w)(6) of this Section is equal to or greater than 80 percent of the PAL level, the Director shall renew the PAL at the same level." 40 CFR 51.166(w)(10)(iv)(b) is not incorporated by reference.

(j)  15A NCAC 02Q .0102 shall not be applicable to any source to which this Rule applies. The owner or operator of the sources to which this Rule applies shall apply for and receive a permit as required in 15A NCAC 02Q .0300 or .0500.

(k)  When a particular source or modification becomes a major stationary source or major modification solely by virtue of a relaxation in any enforceable limitation which was established after August 7, 1980, on the capacity of the source or modification to emit a pollutant, such as a restriction on hours of operation, then the provisions of this Rule shall apply to the source or modification as though construction had not yet begun on the source or modification.

(l)  For the purposes of this Rule, the provisions of 40 CFR 52.21(r)(2) regarding the period of validity of approval to construct are incorporated by reference except that the term "Administrator" shall be replaced with "Director".

(m)  Volatile organic compounds exempted from coverage in 40 CFR 51.100(s) shall be exempted when calculating source applicability and control requirements under this Rule.

(n)  The degree of emission limitation required for control of any air pollutant under this Rule shall not be affected by:

(1)           that amount of a stack height, not in existence before December 31, 1970, that exceeds good engineering practice; or

(2)           any other dispersion technique not implemented before December 31, 1970.

(o)  A substitution or modification of a model as provided in 40 CFR 51.166(l) is subject to public comment procedures in accordance with the requirements of 40 CFR 51.102.

(p)  Permits may be issued on the basis of innovative control technology as set forth in 40 CFR 51.166(s)(1) if the requirements of 40 CFR 51.166(s)(2) have been met, subject to the condition of 40 CFR 51.166(s)(3), and with the allowance set forth in 40 CFR 51.166(s)(4).

(q)  If a source to which this Rule applies impacts an area designated Class I by requirements of 40 CFR 51.166(e), notice to EPA shall be provided as set forth in 40 CFR 51.166(p)(1). If the Federal Land Manager presents a demonstration described in 40 CFR 51.166(p)(3) during the public comment period or public hearing to the Director and if the Director concurs with this demonstration, the permit application shall be denied. Permits may be issued on the basis that the requirements for variances as set forth in 40 CFR 51.166(p)(4), (p)(5) and (p)(7), or (p)(6) and (p)(7) have been satisfied.

(r)  A permit application subject to this Rule shall be processed in accordance with the procedures and requirements of 40 CFR 51.166(q). Within 30 days of receipt of the application, applicants shall be notified if the application is complete as to the initial information submitted. Commencement of construction before full prevention of significant deterioration approval is obtained shall constitute a violation of this Rule.

(s)  Approval of an application with regard to the requirements of this Rule shall not relieve the owner or operator of the responsibility to comply with applicable provisions of other rules of this Subchapter, Subchapter 02Q of this Title, or any other requirements under local, state, or federal law.

(t)  When a source or modification is subject to this Rule the following procedures apply:

(1)           Notwithstanding any other provisions of this Paragraph, the Director shall, no later than 60 days after receipt of an application, notify the Federal Land Manager with the U.S. Department of Interior and U.S. Department of Agriculture of an application from a source or modification subject to this Rule;

(2)           If a source or modification may affect visibility of a Class I area, the Director shall provide written notification to all affected Federal Land Managers within 30 days of receiving the permit application or within 30 days of receiving advance notification of an application. The notification shall be given at least 30 days prior to the publication of notice for public comment on the application. The notification shall include a copy of all information relevant to the permit application, including an analysis provided by the source of the potential impact of the proposed source on visibility;

(3)           The Director shall consider any analysis concerning visibility impairment performed by the Federal Land Manager if the analysis is received within 30 days of notification. If the Director finds that the analysis of the Federal Land Manager fails to demonstrate that an adverse impact on visibility will result in the Class I area, the Director shall follow the public hearing process described in 40 CFR 51.307(a)(3) on the application and include an explanation of the Director's decision or notice as to where the explanation can be obtained; and

(4)           The Director may require monitoring of visibility in or around any Class I area by the proposed new source or modification if the visibility impact analysis indicates possible visibility impairment, pursuant to 40 CFR 51.307.

(u)  If the owner or operator of a source is using projected actual emissions to avoid applicability of prevention of significant deterioration requirements, the owner or operator shall notify the Director of the modification before beginning actual construction. The notification shall include:

(1)           a description of the project;

(2)           identification of sources whose emissions could be affected by the project;

(3)           the calculated projected actual emissions and an explanation of how the projected actual emissions were calculated, including identification of emissions excluded by 40 CFR 51.166(b)(40)(ii)(c);

(4)           the calculated baseline actual emissions and an explanation of how the baseline actual emissions were calculated; and

(5)           any netting calculations, if applicable.

If, upon reviewing the notification, the Director finds that the project will require a prevention of significant deterioration evaluation, the Director shall notify the owner or operator of his or her findings. The owner or operator shall not make the modification until a permit has been issued pursuant to this Rule. If a permit revision is not required pursuant to this Rule, the owner or operator shall maintain records of annual emissions in tons per year, on a calendar year basis related to the modifications, for 10 years following resumption of regular operations after the change if the project involves increasing the emissions unit's design capacity or its potential to emit the regulated NSR pollutant; otherwise, these records shall be maintained for five years following resumption of regular operations after the change. The owner or operator shall submit a report to the Director within 60 days after the end of each year during which these records must be generated. The report shall contain the items listed in 40 CFR 51.166(r)(6)(v)(a) through (c). The owner or operator shall make the information documented and maintained under this Paragraph available to the Director and the general public, pursuant to the requirements in 40 CFR 70.4(b)(3)(viii).

(v)  Portions of the regulations in the Code of Federal Regulations (CFR) that are referred to in this Rule are incorporated by reference unless a specific reference states otherwise. The version of the CFR incorporated in this Rule, with respect to 40 CFR 51.166, is that as of July 1, 2014 at https://www.gpo.gov/fdsys/pkg/CFR-2014-title40-vol2/pdf/CFR-2014-title40-vol2-sec51-166.pdf and does not include any subsequent amendments or editions to the referenced material.

(iv)          For an electric utility steam generating unit, the average rate shall be adjusted downward to reflect any emissions reductions under G.S. 143-215.107D and for which cost recovery is sought pursuant to G.S. 62-133.6;

(v)           For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period shall be used to determine the baseline actual emissions for all the emissions units being changed. A different consecutive 24-month period can be used for each regulated NSR pollutant; and

(vi)          The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by Subparts (ii) and (iii) of this Part;

(B)          For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of such unit shall equal zero; and thereafter, for all other purposes, shall equal the unit's potential to emit; and

(C)          For a plantwide applicability limit (PAL) for a stationary source, the baseline actual emissions shall be calculated for existing emissions units in accordance with the procedures contained in Part (A) of this Subparagraph, and for a new emissions unit in accordance with the procedures contained in Part (B) of this Subparagraph;

(2)           In the definition of "net emissions increase," the reasonable period specified in 40 CFR 51.165(a)(1)(vi)(C)(1) is seven years; and

(3)           Particulate matter PM2.5 significant levels in 40 CFR 51.165(a)(1)(x)(A) are incorporated by reference except as otherwise provided in this Rule.  Sulfur dioxide (SO2) and nitrogen oxides (NOx) are precursors to PM2.5 in all nonattainment areas.  Volatile organic compounds and ammonia are not significant precursors to PM2.5.

(b)  Redesignation to Attainment.  If any county or part of a county to which this Rule applies is later designated in 40 CFR 81.334 as attainment, all sources in that county subject to this Rule before the redesignation date shall continue to comply with this Rule.

(c)  Applicability. 40 CFR 51.165(a)(2) is incorporated by reference.  This Rule applies to areas designated as nonattainment in 40 CFR 81.334, including any subsequent amendments or editions. 

(d)  This Rule is not applicable to:

(1)           complex sources of air pollution regulated only under Section .0800 of this Subchapter and not under any other rule in this Subchapter;

(2)           emission of pollutants at the new major stationary source or major modification located in the nonattainment area that are pollutants other than the pollutant or pollutants for which the area is nonattainment.  (A major stationary source or major modification that is major for volatile organic compounds or nitrogen oxides is also major for ozone.);

(3)           emission of pollutants for which the source or modification is not major;

(4)           a new source or modification that qualifies for exemption under the provision of 40 CFR 51.165(a)(4); or

(5)           emission of compounds listed under 40 CFR 51.100(s) as having been determined to have negligible photochemical reactivity except carbon monoxide.

(e)  15A NCAC 02Q .0102 and .0302 are not applicable to any source to which this Rule applies.  The owner or operator of the source shall apply for and receive a permit as required in 15A NCAC 02Q .0300 or .0500.

(f)  To issue a permit to a source to which this Rule applies, the Director shall determine that the source meets the following requirements:

(1)           The new major stationary source or major modification will emit the nonattainment pollutant at a rate no more than the lowest achievable emission rate;

(2)           The owner or operator of the proposed new major stationary source or major modification has demonstrated that all major stationary sources in the State that are owned or operated by this person (or any entity controlling, controlled by, or under common control with this person) are subject to emission limitations and are in compliance, or on a schedule for compliance that is federally enforceable or contained in a court decree, with all applicable emission limitations and standards of this Subchapter that EPA has authority to approve as elements of the North Carolina State Implementation Plan for Air Quality;

(3)           The owner or operator of the proposed new major stationary source or major modification will obtain sufficient emission reductions of the nonattainment pollutant from other sources in the nonattainment area so that the emissions from the new major source and any associated new minor sources will be less than the emissions reductions by a ratio of at least 1.00 to 1.15 for volatile organic compounds and nitrogen oxides and by a ratio of less than one to one for carbon monoxide. The baseline for this emission offset shall be the actual emissions of the source from which offset credit is obtained.  Emission reductions shall not include any reductions resulting from compliance (or scheduled compliance) with applicable rules in effect before the application.  The difference between the emissions from the new major source and associated new minor sources of carbon monoxide and the emission reductions shall be sufficient to represent reasonable further progress toward attaining the National Ambient Air Quality Standards.  The emissions reduction credits shall also conform to the provisions of 40 CFR 51.165(a)(3)(ii)(A) through (G) and (J); and

(4)           The North Carolina State Implementation Plan for Air Quality is being carried out for the nonattainment area in which the proposed source is located.

(g)  New natural gas-fired electrical utility generating units for which cost recovery is sought pursuant to G.S. 62-133.6 shall install lowest achievable emission rate technology for NOX and SO2, regardless of the applicability of the rest of this Rule.

(h)  For the purposes of this Rule, 40 CFR 51.165(f) is incorporated by reference except that 40 CFR 51.165(f)(10)(iv)(A) reads:  "If the emissions level calculated in accordance with Paragraph (f)(6) of this Section is equal to or greater than 80 percent of the PAL level, the Director shall renew the PAL at the same level."  40 CFR 51.165(f)(10)(iv)(B) is not incorporated by reference.

(i)  When a particular source or modification becomes a major stationary source or major modification solely by virtue of a relaxation in any enforceable limitation established after August 7, 1980, on the capacity of the source or modification to emit a pollutant, such as a restriction on hours of operation, then the provisions of this Rule shall apply to the source or modification as though construction had not yet begun on the source or modification.

(j)  To issue a permit to a source of a nonattainment pollutant, the Director shall determine, in accordance with Section 173(a)(5) of the Clean Air Act and in addition to the other requirements of this Rule, that an analysis (produced by the permit applicant) of alternative sites, sizes, production processes, and environmental control techniques for the source demonstrates that the benefits of the source significantly outweigh the environmental and social costs imposed as a result of its location, construction, or modification.

(k)  For the purposes of this Rule, the provisions of 40 CFR 52.21(r)(2) regarding the period of validity of approval to construct are incorporated by reference except that the term "Administrator" is replaced with "Director."

(l)  Approval of an application regarding the requirements of this Rule does not relieve the owner or operator of the responsibility to comply with applicable provisions of other rules of this Chapter and any other requirements under local, state, or federal law.

(m)  Except as provided in 40 CFR 52.28(c)(6), for a source or modification subject to this Rule the following procedures shall be followed:

(1)  Notwithstanding any other provisions of this Paragraph, the Director shall, no later than 60 days after receipt of an application, notify the Federal Land Manager with the U.S. Department of Interior and U.S. Department of Agriculture of an application from a source or modification subject to this Rule;

(2)           The owner or operator of the source shall provide an analysis of the impairment to visibility that would occur because of the source or modification and general commercial, industrial and other growth associated with the source or modification;

(3)           When a source or modification may affect the visibility of a Class I area, the Director shall provide written notification to all affected Federal Land Managers within 30 days of receiving the permit application or within 30 days of receiving advance notification of an application.  The notification shall be given at least 30 days before the publication of the notice for public comment on the application.  The notification shall include a copy of all information relevant to the permit application, including an analysis provided by the source of the potential impact of the proposed source on visibility;

(4)           The Director shall consider any analysis concerning visibility impairment performed by the Federal Land Manager if the analysis is received within 30 days of notification.  If the Director finds that the analysis of the Federal Land Manager fails to demonstrate to the Director's satisfaction that an adverse impact on visibility will result in the Class I area, the Director shall follow the public hearing process described in 40 CFR 51.307(a)(3) on the application and include an explanation of the Director's decision or notice where the explanation can be obtained;

(5)           The Director shall issue permits only to those sources whose emissions will be consistent with making reasonable progress, as defined in Section 169A of the Clean Air Act, toward the national goal of preventing any future, and remedying any existing, impairment of visibility in mandatory Class I areas when the impairment results from manmade air pollution.  In making the decision to issue a permit, the Director shall consider the cost of compliance, the time necessary for compliance, the energy and nonair quality environmental impacts of compliance, and the useful life of the source; and

(6)           The Director may require monitoring of visibility in or around any Class I area by the proposed new source or modification when the visibility impact analysis indicates possible visibility impairment.

The requirements of this Paragraph do not apply to nonprofit health or nonprofit educational institutions.

(n)  If the owner or operator of a source is using projected actual emissions to avoid applicability of nonattainment new source review, the owner or operator shall notify the Director of the modification before beginning actual construction. The notification shall include:

(1)           a description of the project;

(2)           identification of sources whose emissions could be affected by the project;

(3)           the calculated projected actual emissions and an explanation of how the projected actual emissions were calculated, including identification of emissions excluded by 40 CFR 51.165(a)(1)(xxviii)(B)(3);

(4)           the calculated baseline actual emissions and an explanation of how the baseline actual emissions were calculated; and

(5)           any netting calculations, if applicable.

If upon reviewing the notification, the Director finds that the project will cause a nonattainment new source review evaluation, the Director shall notify the owner or operator of his or her findings.  The owner or operator shall not make the modification until it has received a permit issued pursuant to this Rule.  If a permit revision is not required pursuant to this Rule, the owner or operator shall maintain records of annual emissions in tons per years, on a calendar year basis related to the modifications for 10 years, following resumption of regular operations after the change if the project involves increasing the emissions unit's design capacity or its potential to emit the regulated NSR pollutant; otherwise these records shall be maintained for five years following resumption of regular operations after the change. The owner or operator shall submit a report to the Director within 60 days after the end of each year during which these records must be generated. The report shall contain the items listed in 40 CFR 51.165(a)(6)(v)(A) through (C).  The owner or operator shall make the information documented and maintained under this Paragraph available to the Director and the general public pursuant to the requirements in 40 CFR 70.4(b)(3)(viii).

(o)  The reference to the Code of Federal Regulations (CFR) in this Rule are incorporated by reference unless a specific reference states otherwise. Except for 40 CFR 81.334, the version of the CFR incorporated in this Rule is that as of May 16, 2008 at http://www.gpo.gov/fdsys/pkg/FR-2008-05-16/pdf/E8-10768.pdf and does not include any subsequent amendments or editions to the referenced material.  The publication may be accessed free of charge.

15A NCAC 02D .0532       SOURCES CONTRIBUTING TO AN AMBIENT VIOLATION

(a)  This Rule applies to new major stationary sources and major modifications to which Rule .0531 of this Section does not apply and which would contribute to a violation of a national ambient air quality standard but which would not cause a new violation.

(b)  For the purpose of this Rule the definitions contained in Section II.A. of Appendix S of 40 CFR Part 51 shall apply.

(c)  The Rule is not applicable to:

(1)           complex sources of air pollution that are regulated only under Section .0800 of this Subchapter and not under any other rule of this Subchapter;

(2)           emission of pollutants for which the area in which the new or modified source is located is designated as nonattainment;

(3)           emission of pollutants for which the source or modification is not major;

(4)           emission of pollutants other than sulfur dioxide, total suspended particulates, nitrogen oxides, and carbon monoxide;

(5)           a new or modified source whose impact will increase not more than:

(9)           emissions resulting from the construction phase of the source.

(d)  15A NCAC 2Q .0102 and .0302 are not applicable to any source to which this Rule applies.  The owner or operator of the source shall apply for and receive a permit as required in 15A NCAC 2Q .0300 or .0500.

(e)  To issue a permit to a new or modified source to which this Rule applies, the Director shall determine that the source will meet the following conditions:

(1)           The sources will emit the nonattainment pollutant at a rate no more than the lowest achievable emission rate.

(2)           The owner or operator of the proposed new or modified source has demonstrated that all major stationary sources in the State which are owned or operated by this person (or any entity controlling, controlled by, or under common control with this person) are subject to emission limitations and are in compliance, or on a schedule for compliance which is federally enforceable or contained in a court decree, with all applicable emission limitations and standards of this Subchapter which EPA has authority to approve as elements of the North Carolina State Implementation Plan for Air Quality.

15A NCAC 02D .0533       STACK HEIGHT

(a)  For the purpose of this Rule, the following definitions apply:

(1)           "Stack" means any point in a source designed to emit solids, liquids, or gases into the air, including a pipe or duct but not including flares.

(2)           "A stack in existence" means that the owner or operator had:

(A)          begun, or caused to begin, a continuous program of physical on‑site construction of the stack; or

(B)          entered into binding agreements or contractual obligations, which could not be canceled or modified without substantial loss to the owner or operator, to undertake a program of construction of the stack to be completed in the time that is normally required to construct such a stack.

(3)           "Dispersion technique"

(A)          "Dispersion technique" means any technique which attempts to affect the concentration of a pollutant in the ambient air by:

(i)            using that portion of a stack which exceeds good engineering practice stack height,

(ii)           varying the rate of emission of a pollutant according to atmospheric conditions or ambient concentrations of that pollutant, or

(iii)          increasing final exhaust gas plume rise by manipulating source process parameters, exhaust gas parameters, stack parameters, or combining exhaust gases from several existing stacks into one stack; or other selective handling of exhaust gas streams so as to increase the exhaust gas plume rise.

(B)          "Dispersion technique" does not include:

(i)            the reheating of a gas stream, following use of a pollution control system, for the purpose of returning the gas to the temperature at which it was originally discharged from the facility generating the gas stream;

(ii)           the using of smoke management in agricultural or silvicultural prescribed burning programs;

(iii)          the merging of exhaust gas streams where:

(I)            The facility owner or operator demonstrates that the source was originally designed and constructed with such merged gas streams;

(II)          After July 8, 1985, such merging is part of a change in operation at the facility that includes the installation of pollution controls and is accompanied by a net reduction in the allowable emissions of a pollutant.  This exclusion from the definition of "dispersion techniques" shall apply only to the emission limitation for the pollutant affected by such change in operation; or

(III)        Before July 8, 1985, such merging was part of a change in operation at the source that included the installation of emissions control equipment or was carried out for sound economic or engineering reasons.  Where there was an increase in the emission limitation or in the event that no emission limitation was in existence prior to the merging, an increase in the quantity of pollutants actually emitted prior to the merging, the Director shall presume that merging was significantly motivated by an intent to gain emissions credit for greater dispersion.  Absent a demonstration by the source owner or operator that merging was not significantly motivated by such intent, the Director shall deny credit for the effects of such merging in calculating the allowable emissions for the source;

(iv)          Episodic restrictions on residential woodburning and open burning; or

(v)           Techniques under Subpart (A)(iii) of this Subparagraph which increase final exhaust gas plume rise where the resulting allowable emissions of sulfur dioxide from the facility do not exceed 5,000 tons per year.

(4)           "Good engineering practice (GEP) stack height" means the greater of:

(A)          65 meters measured from the ground‑level elevation at the base of the stack;

(B)          2.5 times the height of nearby structure(s) measured from the ground‑level elevation at the base of the stack for stacks in existence on January 12, 1979 and for which the owner or operator had obtained all applicable permit or approvals required under 15A NCAC 2Q and 40 CFR Parts 51 and 52, provided the owner or operator produces evidence that this equation was actually relied on in establishing an emission limitation;

(C)          for stacks not covered under Part (B) of this Subparagraph, the height of nearby structure(s) measured from the ground‑level elevation at the base of the stack plus 1.5 times the lesser dimension (height or projected width) of nearby structure(s) provided that the Director may require the use of a field study or fluid model to verify GEP stack height for the source; or

(D)          the height demonstrated by a fluid model or a field study approved by the Director, which ensures that the emissions from a stack do not result in excessive concentrations of any air pollutant as a result of atmospheric downwash, wakes, or eddy effects created by the source itself, nearby structures or nearby terrain features.

(5)           "Nearby" means, for a specific structure or terrain feature:

(A)          under Parts (4)(B) and (C) of this Paragraph, that distance up to five times the lesser of the height or the width dimension of a structure but not greater than one‑half mile.  The height of the structure is measured from the ground‑level elevation at the base of the stack.

(B)          under Part (4)(D) of this Paragraph, not greater than one‑half mile, except that the portion of a terrain feature may be considered to be nearby which falls within a distance of up to 10 times the maximum height [Ht] of the feature, not to exceed two miles if such feature achieves a height [ht] one‑half mile from the stack that is at least 40 percent of the GEP stack height determined by Part (4)(C) of this Paragraph or 26 meters, whichever is greater, as measured from the ground‑level elevation at the base of the stack.  The height of the structure or terrain feature is measured from the ground‑level elevation at the base of the stack.

(6)           "Excessive concentrations" means, for the purpose of determining good engineering practice stack height under Part (4)(D) of this Paragraph:

(A)          for sources seeking credit for stack height exceeding that established under Part (4)(B) or (C) of this Paragraph, a maximum ground‑level concentration due to emissions from a stack due in whole or part to downwash, wakes, and eddy effects produced by nearby structures or nearby terrain features which individually is at least 40 percent in excess of the maximum concentration experienced in the absence of such downwash, wakes, or eddy effects and which contributes to a total concentration due to emissions from all sources that is greater than an ambient air quality standard.  For sources subject to Rule .0530 of this Section, an excessive concentration alternatively means a maximum ground‑level concentration due to emissions from a stack due in whole or part to downwash, wakes, or eddy effects produced by nearby structures or nearby terrain features which individually is at least 40 percent in excess of the maximum concentration experienced in the absence of such downwash, wakes, or eddy effects and greater than a prevention of significant deterioration increment.  The allowable emission rate to be used in making demonstrations under this Part shall be prescribed by the new source performance standard that is applicable to the source category unless the owner or operator demonstrates that this emission rate is infeasible.  Where such demonstrations are approved by the Director, an alternative emission rate shall be established in consultation with the source owner or operator;

(B)          for sources seeking credit after October 11, 1983, for increases in existing stack heights up to the heights established under Part (4)(B) or (C) of this Paragraph:

(i)            a maximum ground‑level concentration due in whole or part to downwash, wakes or eddy effects as provided in Part (A) of this Subparagraph, except that the emission rate specified by any applicable Rule in this Subchapter (or, in the absence of such a limit, the actual emission rate) shall be used, or

(ii)           the actual presence of a local nuisance (odor, visibility impairment, or pollutant concentration) caused by the existing stack, as determined by the Director; and

(C)          for sources seeking credit after January 12, 1979, for a stack height determined under Part (4)(B) or (C) of this Paragraph where the Director requires the use of a field study or fluid model to verify GEP stack height, for sources seeking stack height credit after November 9, 1984 based on the aerodynamic influence of cooling towers, and for sources seeking stack height credit after December 31, 1970 based on the aerodynamic influence of structures not adequately represented by Part (4)(B) or (C) of this Paragraph, a maximum ground‑level concentration due in whole or part to downwash, wakes, or eddy effects that is at least 40 percent in excess of the maximum concentration experienced in the absence of such downwash, wakes, or eddy effects.

(7)           "Emission limitation" means a requirement established by this Subchapter or a local air quality program certified by the Commission that limits the quantity, rate, or concentration of emissions of air pollutants on a continuous basis, including any requirements that limit the level of opacity, prescribe equipment, set fuel specifications, or prescribe operation or maintenance procedures for a source to assure continuous emission reduction.

(b)  With the exception stated in Paragraphs (c) and (d) of this Rule, the degree of emission limitations required by any rule in this Subchapter shall not be affected by:

(1)           that amount of a stack height that exceeds good engineering practice; or

(2)           any other dispersion technique.

(c)  Paragraph (b) shall not apply to:

(1)           stack heights in existence or dispersion techniques implemented before December 31, 1970, except where pollutants are being emitted from such stacks or using such dispersion techniques by sources, as defined in Section 111(a)(3) of the Clean Air Act, which were constructed, or reconstructed, or for which major modifications, as defined in Rules .0530 (b) and .0531 (b) of this Section were carried out after December 31, 1970; or

(2)           coal‑fired steam electric generating units, subject to provisions of Section 118 of the federal Clean Air Act, which began operation before July 1, 1957, and whose stacks were constructed under a construction contract awarded before February 8, 1974.

However, these exemptions shall not apply to a new stack that replaces a stack that is exempted by Subparagraphs (1) and (2) of this Paragraph. These exemptions shall not apply to a new source using a stack that is exempted by Subparagraphs (1) and (2) of this Paragraph.

(d)  This Rule shall not restrict the actual stack height of any source.

(a)  For this Rule the following definitions apply:

(1)           "Excess Emissions" means an emission rate that exceeds any applicable emission limitation or standard allowed by any rule in Sections .0500, .0900, .1200, or .1400 of this Subchapter; or by a permit condition; or that exceeds an emission limit established in a permit issued under 15A NCAC 02Q .0700.

(2)           "Malfunction" means any unavoidable failure of air pollution control equipment, process equipment, or process to operate in a normal and usual manner that results in excess emissions.  Excess emissions during periods of routine start-up and shut-down of process equipment are not considered a malfunction.  Failures caused entirely or in part by poor maintenance, careless operations or any other upset condition within the control of the emission source are not considered a malfunction.

(3)           "Start-up" means the commencement of operation of any source that has shut-down or ceased operation for a period sufficient to cause temperature, pressure, process, chemical, or a pollution control device imbalance that would result in excess emission.

(4)           "Shut-down" means the cessation of the operation of any source for any purpose.

(b)  This Rule does not apply to sources to which Rules .0524, .1110, or .1111 of this Subchapter applies unless excess emissions exceed an emission limit established in a permit issued under 15A NCAC 02Q .0700 that is more stringent than the emission limit set by Rules .0524, .1110 or .1111 of this Subchapter.

(c)  Any excess emissions that do not occur during start-up or shut-down are considered a violation of the appropriate rule unless the owner or operator of the source of excess emissions demonstrates to the Director, that the excess emissions are the result of a malfunction.  To determine if the excess emissions are the result of a malfunction, the Director shall consider, along with any other pertinent information, the following:

(1)           The air cleaning device, process equipment, or process has been maintained and operated, to the maximum extent practicable, consistent with good practice for minimizing emissions;

(2)           Repairs have been made expeditiously when the emission limits have been exceeded;

(3)           The amount and duration of the excess emissions, including any bypass, have been minimized to the maximum extent practicable;

(4)           All practical steps have been taken to minimize the impact of the excess emissions on ambient air quality;

(5)           The excess emissions are not part of a recurring pattern indicative of inadequate design, operation, or maintenance;

(6)           The requirements of Paragraph (f) of this Rule have been met; and

(7)           If the source is required to have a malfunction abatement plan, it has followed that plan.  All malfunctions shall be repaired as expeditiously as practicable.  However, the Director shall not excuse excess emissions caused by malfunctions from a source for more than 15 percent of the operating time during each calendar year.  The Director may require the owner or operator of a facility to maintain records of the time that a source operates when it or its air pollution control equipment is malfunctioning or otherwise has excess emissions.

(d)  All electric utility boiler units shall have a malfunction abatement plan approved by the Director as satisfying the requirements of Subparagraphs (1) through (3) of this Paragraph.  In addition, the Director may require any other source to have a malfunction abatement plan approved by the Director as satisfying the requirements of Subparagraphs (1) through (3) of this Paragraph.  If the Director requires a malfunction abatement plan for a source other than an electric utility boiler, the owner or operator of that source shall submit a malfunction abatement plan within 60 days after receipt of the Director's request.  The malfunction plans of electric utility boiler units and of other sources required to have them shall be implemented when a malfunction or other breakdown occurs.  The purpose of the malfunction abatement plan is to prevent, detect, and correct malfunctions or equipment failures that could result in excess emissions.  A malfunction abatement plan shall contain:

(1)           a complete preventive maintenance program including:

(A)          the identification of individuals or positions responsible for inspecting, maintaining and repairing air cleaning devices;

(B)          a description of the items or conditions that will be inspected and maintained;

(C)          the frequency of the inspection, maintenance services, and repairs; and

(D)          an identification and quantities of the replacement parts that shall be maintained in inventory for quick replacement;

(2)           an identification of the source and air cleaning operating variables and outlet variables, such as opacity, grain loading, and pollutant concentration, that may be monitored to detect a malfunction or failure; the normal operating range of these variables and a description of the method of monitoring or surveillance procedures and of informing operating personnel of any malfunctions, including alarm systems, lights or other indicators; and

(3)           a description of the corrective procedures that the owner or operator will take in case of a malfunction or failure to achieve compliance with the applicable rule as expeditiously as practicable but no longer than the next boiler or process outage that would provide for an orderly repair or correction of the malfunction or 15 days, whichever is shorter.  If the owner or operator anticipates that the malfunction would continue for more than 15 days, a case-by-case repair schedule shall be established by the Director with the source.  The owner or operator shall maintain logs to show that the operation and maintenance parts of the malfunction abatement plan are implemented.  These logs are subject to inspection by the Director or his designee upon request during business hours.

(e)  The owner or operator of any source required by the Director to have a malfunction abatement plan shall submit a malfunction abatement plan to the Director within six months after it has been required by the Director.  The malfunction abatement plan and any amendment to it shall be reviewed by the Director or his designee.  If the plan carries out the objectives described by Paragraph (d) of this Rule, the Director shall approve it. If the plan does not carry out the objectives described by Paragraph (d) of this Rule, the Director shall disapprove the plan.  The Director shall state his reasons for his disapproval. The person who submits the plan shall submit an amendment to the plan to satisfy the reasons for the Director's disapproval within 30 days of receipt of the Director's notification of disapproval.  Any person having an approved malfunction abatement plan shall submit to the Director for his approval amendments reflecting changes in any element of the plan required by Paragraph (d) of this Rule or amendments when requested by the Director.  The malfunction abatement plan and amendments to it shall be implemented within 90 days upon receipt of written notice of approval.

(f)  The owner or operator of a source of excess emissions that last for more than four hours and that results from a malfunction, a breakdown of process or control equipment or any other abnormal conditions, shall:

(1)           notify the Director or his designee of any such occurrence by 9:00 a.m. Eastern time of the Division's next business day of becoming aware of the occurrence and describe:

(A)          name and location of the facility,

(B)          the nature and cause of the malfunction or breakdown,

(C)          the time when the malfunction or breakdown is first observed,

(D)          the expected duration, and

(E)           an estimated rate of emissions;

(2)           notify the Director or his designee immediately when the corrective measures have been accomplished;

(3)           submit to the Director within 15 days after the request a written report that includes:

(A)          name and location of the facility,

(B)          identification or description of the processes and control devices involved in the malfunction or breakdown,

(C)          the cause and nature of the event,

(D)          time and duration of the violation or the expected duration of the excess emission if the malfunction or breakdown has not been fixed,

(E)           estimated quantity of pollutant emitted,

(F)           steps taken to control the emissions and to prevent recurrences and if the malfunction or breakdown has not been fixed, steps planned to be taken, and

(G)          any other pertinent information requested by the Director.  After the malfunction or breakdown has been corrected, the Director may require the owner or operator of the source to test the source in accordance with Section .2600 of this Subchapter to demonstrate compliance.

(g)  Start-up and shut-down.  Excess emissions during start-up and shut-down are considered a violation of the appropriate rule if the owner or operator cannot demonstrate that the excess emissions are unavoidable.  To determine if excess emissions are unavoidable during startup or shutdown the Director shall consider the items listed in Paragraphs (c)(1), (c)(3), (c)(4), (c)(5), and (c)(7) of this Rule along with any other pertinent information.  The Director may specify for a particular source the amount, time, and duration of emissions allowed during start-up or shut-down.  The owner or operator shall, to the extent practicable, operate the source and any associated air pollution control equipment or monitoring equipment in a manner consistent with best practicable air pollution control practices to minimize emissions during start-up and shut-down.

15A NCAC 02D .0536       PARTICULATE EMISSIONS FROM ELECTRIC UTILITY BOILERS

(a)  The purpose of this Rule is to establish particulate and visible emission limits for the listed units by utilizing control technology to protect the public health and welfare of the State and its citizens.

(b)  Notwithstanding Rule .0503 of this Section, emissions of particulate matter from the utility boiler units specified in the following table shall not exceed the maximum emission rate in the table as measured by a stack test conducted in accordance with Section .2600 of this Subchapter.  The results of any stack test shall be reported within 30 days, and the test report shall be submitted within 60 days after the test. In addition to limitations contained in Rule .0521 of this Section, visible emissions from the utility boiler units specified in the table shall not exceed the annual average opacity limits in the table. Each day an annual average opacity value shall be calculated for each unit for the most recent 365-day period ending with the end of the previous day.  The average is the sum of the measured non-overlapping six-minute averages of opacity determined only while the unit is in operation divided by the number of such measured non-overlapping six-minute averages.  Start-up, shut-down, and non-operating time shall not be included in the annual average opacity calculation, but malfunction time shall be included, Rule .0535 of this Section notwithstanding.  The Director may approve an alternate method of calculating the annual average opacity if:

(1)           the alternate method is submitted by the electric utility company,

(2)           the director concludes that the alternate method will not cause a systematic or unacceptable difference in calculated values from the specified method, and

(3)           it is mutually agreed that the values calculated using the alternate method can be used for enforcement purposes.

The owner or operator of each unit shall submit a report to the Director by the 30th day following the end of each month. This report shall show for each day of the previous month the calculated annual average opacity of each unit and the annual average opacity limit. If a violation occurs, the owner or operator of the unit shall immediately notify the Director.

15A NCAC 02D .0542       CONTROL OF PARTICULATE EMISSIONS FROM COTTON GINNING OPERATIONS

(a)  Purpose. The purpose of this Rule is to establish control requirements for particulate emissions from cotton ginning operations.

(b)  Definitions. For the purposes of this Rule the following definitions apply:

(1)           "1D-3D cyclone" means any cyclone-type collector of the 1D-3D configuration. This designation refers to the ratio of the cylinder to cone length, where D is the diameter of the cylinder portion. A 1D-3D cyclone has a cylinder length of 1xD and a cone length of 3xD.

(2)           "2D-2D cyclone" means any cyclone-type collector of the 2D-2D configuration.  This designation refers to the ratio of the cylinder to cone length, where D is the diameter of the cylinder portion. A 2D-2D cyclone has a cylinder length of 2xD and a cone length of 2xD.

(3)           "Bale" means a compressed and bound package of cotton lint, nominally weighing 500 pounds.

(4)           "Existing facility" means a cotton ginning operation that operated prior to July 1, 2002.

(5)           "Ginning operation" means any facility or plant that removes seed, lint, and trash or one or more combination of these from raw cotton or bales of lint cotton.

(6)           "Ginning season" means the period of time during which the gin is in operation, which is generally from September of the current year through January of the following year.

(7)           "High pressure exhausts" means the exhaust air systems at a cotton gin that are not defined as "low pressure exhausts."

(8)           "Low pressure exhausts" means the exhaust cotton handling systems located at a cotton gin that handle air from the cotton lint handling system and battery condenser.

(c)  Applicability. This rule applies to all existing, new, and modified cotton ginning operations. Existing facilities with a maximum rated capacity of less than 20 bales per hour that do not have cyclones on lint cleaners and battery condensers as of July 1, 2002 are not be required to add:

(1)           the emission control devices in Paragraph (d)(1) of this Rule to lint cleaning exhausts if emissions from the lint cleaning are controlled by fine mesh screens; and

(2)           the emission control devices in Paragraph (d)(2) of this Rule to battery condenser exhausts if the emissions from the battery condenser are controlled by fine mesh screens.

(d)  Emission Control Requirements.  The owner or operator of each cotton ginning operation shall control particulate emissions from the facility by controlling:

(1)           all high pressure exhausts and lint cleaning exhausts with an emission control system that includes:

(A)          one or more 1D-3D or 2D-2D cyclones to achieve 95 percent efficiency; or

(B)          a device with a minimum of 95 percent efficiency.

(2)           low pressure exhausts, except lint cleaning exhausts, by an emission control system that includes:

(A)          one or more 1D-3D or 2D-2D cyclones to achieve 90 percent efficiency; or

(B)          a device with at least a 90 percent efficiency.

Efficiency is based on the removal of particulate matter between the cyclone's inlet and outlet; it is measured using test methods in Section .2600 of this Subchapter.

(e)  Raincaps.  Exhausts from emission points or control devices shall not be equipped with raincaps or other devices that deflect the emissions downward or outward.

(f)  Operation and Maintenance. To ensure that optimum control efficiency is maintained, the owner or operator shall establish, based on manufacturers recommendations, an inspection and maintenance schedule for the control devices, other emission processing equipment, and monitoring devices that are used pursuant to this Rule. The inspection and maintenance schedule shall be followed throughout the ginning season. The results of the inspections and any maintenance performed on the control equipment, emission processing equipment, or monitoring devices shall be recorded in the log book required in Paragraph (k) of this Rule.

(g)  Fugitive Emissions. The owner or operator shall minimize fugitive emissions from cotton ginning operations as follows.

(1)           The owner or operator of a

(A)          trash stacker shall:

(i)            install, maintain, and operate a three sided enclosure with a roof whose sides are high enough above the opening of the dumping  device to prevent wind from dispersing dust or debris; or

(ii)           install, maintain, and operate a device to provide wet suppression at the dump area of the trash cyclone and minimize free fall distance of waste material exiting the trash cyclone; or

(B)          trash stacker/trash composting system shall install, maintain, and operate a wet suppression system providing dust suppression in the auger box assembly and at the dump area of the trash stacker system. The owner or operator shall keep the trash material wet and compost it in place until the material is removed from the dump area for additional composting or disposal.

(2)           Gin Yard. The owner or operator shall clean and dispose of accumulations of trash or lint on the non-storage areas of the gin yard daily.

(3)           Traffic areas. The owner or operator shall clean paved roadways, parking, and other traffic areas at the facility as necessary to prevent re-entrainment of dust or debris.  The owner or operator shall treat unpaved roadways, parking, and other traffic areas at the facility with wet or chemical dust suppressant as necessary to prevent dust from leaving the facility's property and shall install and maintain signs limiting vehicle speed to 10 miles per hour where chemical suppression is used and to 15 miles per hour where wet suppression is used.

(4)           Transport of Trash Material.  The owner or operator shall ensure that all trucks transporting gin trash material are covered and that the trucks are cleaned of over-spill material before trucks leave the trash hopper dump area.  The dump area shall be cleaned daily.

(h)  Alternative Control Measures.  The owner or operator of a ginning operation may petition for use of alternative control measures to those specified in this Rule.  The petition shall include:

(1)           the name and address of the petitioner;

(2)           the location and description of the ginning operation;

(3)           a description of the alternative control measure;

(4)           a demonstration that the alternative control measure is at least as effective as the control device or method specified in this Rule.

(i)  Approval of Alternative Control Measure.  The Director shall approve the alternative control measure if he finds that:

(1)           all the information required by Paragraph (h) of this Rule has been submitted; and

(2)           the alternative control measure is at least as effective as the control device or method specified in this Rule.

(j)  Monitoring.

(1)           The owner or operator of each ginning operation shall install, maintain, and calibrate monitoring devices that measure pressures, rates of flow, and other operating conditions necessary to determine if the control devices are functioning properly.

(2)           Before or during the first week of operation of the 2002-2003 ginning season, the owner or operator of each gin shall conduct a baseline study of the entire dust collection system, without cotton being processed, to ensure air flows are within the design range for each collection device.  For 2D-2D cyclones the air flow design range is 2600 to 3600 feet per minute. For 1D-3D cyclones the design range is 2800 to 3600 feet per minute. For other control devices the air flow design range is that found in the manufacturer's specifications.  Gins constructed after the 2002-2003 ginning season shall conduct the baseline study before or during the first week of operation of the first ginning season following construction.  During the baseline study the owner or operator shall measure or determine according to the methods specified in this Paragraph and record in a logbook:

(A)          the calculated inlet velocity for each control device; and

(B)          the pressure drop across each control device.

The owner or operator shall use Method 1 and Method 2 of 40 CFR Part 60 Appendix A to measure flow and static pressure and determine inlet velocity or the USDA method for determining duct velocity and static pressure in Agricultural Handbook Number 503, Cotton Ginners Handbook, dated December 1994.  The Cotton Ginners Handbook method shall only be used where test holes are located a minimum of eight and one-half pipe diameters downstream and one and one-half pipe diameters upstream from elbows, valves, dampers, changes in duct diameter or any other flow disturbances.  Where Method 2 is used a standard pitot tube may be used in lieu of the s-pitot specified in Method 2 subject to the conditions specified in Paragraph 2.1 of Method 2.

(3)           On a monthly basis following the baseline study, the owner or operator shall measure and record in the logbook the static pressure at each port where the static pressure was measured in the baseline study. Measurements shall be made using a manometer, a Magnahelic® gauge, or other device that the Director has approved as being equivalent to a manometer.  If the owner or operator measures a change in static pressure of 20 percent or more from that measured in the baseline study, the owner or operator shall initiate corrective action.  Corrective action shall be recorded in the logbook. If corrective action will take more than 48 hours to complete, the owner or operator shall notify the regional supervisor of the region in which the ginning operation is located as soon as possible, but by no later than the end of the day such static pressure is measured.

(4)           When any design changes to the dust control system are made, the owner or operator shall conduct a new baseline study for that portion of the system and shall record the new values in the logbook required in Paragraph (k) of this Rule.  Thereafter monthly static pressure readings for that portion of the system shall be compared to the new values.

(5)           During the ginning season, the owner or operator shall daily inspect for structural integrity of the control devices and other emissions processing systems and shall ensure that the control devices and emission processing systems conform to normal and proper operation of the gin.  If a problem is found, corrective action shall be taken and recorded in the logbook required in Paragraph (k) of this Rule.

(6)           At the conclusion of the ginning season, the owner or operator shall conduct an inspection of the facility to identify all scheduled maintenance activities and repairs needed relating to the maintenance and proper operation of the air pollution control devices for the next season.  Any deficiencies identified through the inspection shall be corrected before beginning operation of the gin for the next season.

(k)  Recordkeeping. The owner operator shall establish and maintain on-site a logbook documenting the following items:

(1)           Results of the baseline study as specified in Paragraph (j)(2) of this Rule;

(2)           Results of new baseline studies as specified in Paragraph (j)(4) of this Rule;

(3)           Results of monthly static pressure checks and any corrective action taken as specified in Paragraph (j)(3) of this Rule;

(4)           Observations from daily inspections of the facility and any resulting corrective actions taken as required in Paragraph (j)(5) of this Rule; and

(5)           A copy of the manufacturer's specifications for each type of control device installed.

The logbook shall be maintained on site and made available to Division representatives upon request.

(l)  Reporting. The owner or operator shall submit by March 1 of each year a report containing the following:

(1)           the name and location of the cotton gin;

(2)           the number of bales of cotton produced during the previous ginning season;

(3)           a maintenance and repair schedule based on inspection of the facility at the conclusion of the previous cotton ginning season required in Paragraph (j)(6) of this Rule; and

(4)           signature of the appropriate official as identified in 15A NCAC 02Q .0304(j), certifying as to the truth and accuracy of the report.

(m)  Compliance Schedule.  Existing sources shall comply as specified in Paragraph (d) of this Rule. New and modified sources shall be in compliance upon start-up.

(n)  Record retention.  The owner or operator shall retain all records required to be kept by this Rule for three years from the date of recording.

15A NCAC 02D .0544       PREVENTION OF SIGNIFICANT DETERIORATION Requirements FOR GreeNHouse GASES

(a)  The purpose of this Rule is to implement a program for the prevention of significant deterioration of air quality for greenhouse gases as required by 40 CFR 51.166.  For purposes of greenhouse gases, the provisions of this Rule shall apply rather than the provisions of Rule .0530 of this Section.  A major stationary source or major modification shall not be required to obtain a prevention of significant deterioration (PSD) permit on the sole basis of its greenhouse gases emissions.  For all other regulated new source review (NSR) pollutants, the provisions of Rule .0530 of this Section apply.

(b)  For the purposes of this Rule, the definitions contained in 40 CFR 51.166(b) and 40 CFR 51.301 shall apply except the definition of "baseline actual emissions."  "Baseline actual emissions" means the rate of emissions, in tons per year, of a regulated NSR pollutant, as determined in accordance with Subparagraphs (1) through (3) of this Paragraph:

(1)           For an existing emissions unit, baseline actual emissions means the average rate, in tons per year, at which the emissions unit emitted the pollutant during any consecutive 24-month period selected by the owner or operator within the 5-year period preceding the date that a complete permit application is received by the Division for a permit required under this Rule. The Director shall allow a different time period, not to exceed 10 years preceding the date that a complete permit application is received by the Division, if the owner or operator demonstrates that it is more representative of normal source operation.  For the purpose of determining baseline actual emissions, the following shall apply:

(A)          The average rate shall include fugitive emissions to the extent quantifiable, and emissions associated with startups, shutdowns, and malfunctions;

(B)          The average rate shall be adjusted downward to exclude any non-compliant emissions that occurred while the source was operating above any emission limitation that was legally enforceable during the consecutive 24-month period;

(C)          For an existing emission unit (other than an electric utility steam generating unit), the average rate shall be adjusted downward to exclude any emissions that would have exceeded an emission limitation with which the major stationary source shall currently comply. However, if the State has taken credit in an attainment demonstration or maintenance plan consistent with the requirements of 40 CFR 51.165(a)(3)(ii)(G) for an emission limitation that is part of a maximum achievable control technology standard that the Administrator proposed or promulgated under part 63 of the Code of Federal Regulations, the baseline actual emissions shall be adjusted to account for such emission reductions;

(D)          For an electric utility steam generating unit, the average rate shall be adjusted downward to reflect any emissions reductions under G.S. 143-215.107D and for which cost recovery is sought pursuant to G.S. 62-133.6;

(E)           For a regulated NSR pollutant, when a project involves multiple emissions units, only one consecutive 24-month period shall be used to determine the baseline actual emissions for all the emissions units being changed. A different consecutive 24-month period for each regulated NSR pollutant can be used for each regulated NSR pollutant; and

(F)           The average rate shall not be based on any consecutive 24-month period for which there is inadequate information for determining annual emissions, in tons per year, and for adjusting this amount if required by Parts (B) and (C) of this Subparagraph;

(2)           For a new emissions unit, the baseline actual emissions for purposes of determining the emissions increase that will result from the initial construction and operation of such unit shall equal zero; and thereafter, for all other purposes, shall equal the unit's potential to emit; and

(3)           For a plantwide applicability limit (PAL) for a stationary source, the baseline actual emissions shall be calculated for existing emissions units in accordance with the procedures contained in Subparagraph (1) of this Paragraph and for a new emissions unit in accordance with the procedures contained in Subparagraph (2) of this Paragraph.

(c)  In the definition of "net emissions increase," the reasonable period specified in 40 CFR 51.166(b)(3)(ii) shall be seven years.

(d)  In the definition of "subject to regulation", a greenhouse gas's global warming potential is the global warming potential published at Table A-1 of Subpart A of 40 CFR Part 98 and shall include subsequent amendments and editions.

(e)  The limitation specified in 40 CFR 51.166(b)(15)(ii) shall not apply.

(f)  Major stationary sources and major modifications shall comply with the requirements contained in 40 CFR 51.166(i) and (a)(7) and by extension in 40 CFR 51.166(j) through (o) and (w). The transition provisions allowed by 40 CFR 52.21 (i)(11)(i) and (ii) and (m)(1)(vii) and (viii) are hereby adopted under this Rule. The minimum requirements described in the portions of 40 CFR 51.166 referenced in this Paragraph are hereby adopted as the requirements to be used under this Rule, except as otherwise provided in this Rule. Wherever the language of the portions of 40 CFR 51.166 referenced in this Paragraph speaks of the "plan," the requirements described therein shall apply to the source to which they pertain, except as otherwise provided in this Rule. Whenever the portions of 40 CFR 51.166 referenced in this Paragraph provide that the State plan may exempt or not apply certain requirements in certain circumstances, those exemptions and provisions of nonapplicability are also hereby adopted under this Rule. However, this provision shall not be interpreted so as to limit information that may be requested from the owner or operator by the Director as specified in 40 CFR 51.166(n)(2).

(g)  40 CFR 51.166(w)(10)(iv)(a) is changed to read: "If the emissions level calculated in accordance with Paragraph (w)(6) of this Section is equal to or greater than 80 percent of the PAL [plant wide applicability limit] level, the Director shall renew the PAL at the same level." 40 CFR 51.166(w)(10)(iv)(b) is not incorporated by reference.

(h)  15A NCAC 02Q .0102 and .0302 are not applicable to any source to which this Rule applies.  The owner or operator of the sources to which this Rule applies shall apply for and receive a permit as required in 15A NCAC 02Q .0300 or .0500.

(i)  When a particular source or modification becomes a major stationary source or major modification solely by virtue of a relaxation in any enforceable limitation that was established after August 7, 1980, on the capacity of the source or modification to emit a pollutant, such as a restriction on hours of operation, then the provisions of this Rule shall apply to the source or modification as though construction had not yet begun on the source or modification.

(j)  The provisions of 40 CFR 52.21(r)(2) regarding the period of validity of approval to construct are incorporated by reference except that the term "Administrator" is replaced with "Director".

(k)  Permits may be issued based on innovative control technology as set forth in 40 CFR 51.166(s)(1) if the requirements of 40 CFR 51.166(s)(2) have been met, subject to the condition of 40 CFR 51.166(s)(3), and with the allowance set forth in 40 CFR 51.166(s)(4).

(l)  A permit application subject to this Rule shall be processed in accordance with the procedures and requirements of 40 CFR 51.166(q).  Within 30 days of receipt of the application, applicants shall be notified if the application is complete as to initial information submitted. Commencement of construction before full prevention of significant deterioration approval is obtained constitutes a violation of this Rule.

(m)  Approval of an application with regard to the requirements of this Rule shall not relieve the owner or operator of the responsibility to comply with applicable provisions of other rules of this Subchapter or Subchapter 02Q of this Title and any other requirements under local, state, or federal law.

(n)  If the owner or operator of a source is using projected actual emissions to avoid applicability of prevention of significant deterioration requirements, the owner or operator shall notify the Director of the modification before beginning actual construction.  The notification shall include:

(1)           a description of the project;

(2)           identification of sources whose emissions could be affected by the project;

(3)           the calculated projected actual emissions and an explanation of how the projected actual emissions were calculated, including identification of emissions excluded by 40 CFR 51.166(b)(40)(ii)(c);

(4)           the calculated baseline actual emissions and an explanation of how the baseline actual emissions were calculated; and

(5)           any netting calculations, if applicable.

If upon reviewing the notification, the Director finds that the project will cause a prevention of significant deterioration evaluation, then the Director shall notify the owner or operator of his or her findings.  The owner or operator shall not make the modification until the owner or operator has received a permit issued pursuant to this Rule. If a permit revision is not required pursuant to this Rule, the owner or operator shall maintain records of annual emissions in tons per year, on a calendar year basis related to the modifications for 10 years following resumption of regular operations after the change if the project involves increasing the emissions unit's design capacity or its potential to emit the regulated NSR pollutant; otherwise these records shall be maintained for five years following resumption of regular operations after the change. The owner or operator shall submit a report to the Director within 60 days after the end of each year during which these records must be generated. The report shall contain the items listed in 40 CFR 51.166(r)(6)(v)(a) through (c).  The owner or operator shall make the information documented and maintained under this Paragraph available to the Director or the general public pursuant to the requirements in 40 CFR 70.4(b)(3)(viii).

(o)  The references to the Code of Federal Regulations (CFR) in this Rule are incorporated by reference unless a specific reference states otherwise. The version of the CFR incorporated in this Rule is that as of July 20, 2011 as set forth here http://www.gpo.gov/fdsys/pkg/CFR-2011-title40-vol2/pdf/CFR-2011-title40-vol2-sec51-166.pdf, http://www.gpo.gov/fdsys/pkg/CFR-2011-title40-vol3/pdf/CFR-2011-title40-vol3-sec52-21.pdf, and with the amendment set forth on 76 FR 43507 at http://www.gpo.gov/fdsys/pkg/FR-2011-07-20/pdf/2011-17256.pdf and does not include any subsequent amendments or editions to the referenced material.  This Rule is applicable in accordance with 40 CFR 51.166(b)(48) and (b)(49)(iv) and (v).

15A NCAC 02D .0606       SOURCES COVERED BY APPENDIX P OF 40 CFR PART 51

(a)  The following sources shall be monitored as described in Paragraph 2 of Appendix P of 40 CFR Part 51:

(1)           fossil fuel-fired steam generators,

(2)           nitric acid plants,

(3)           sulfuric acid plants, and

(4)           petroleum refineries.

Sources covered by Rule .0524 of this Subchapter are exempt from this Rule.

(b)  The monitoring systems required under Paragraph (a) of this Rule shall meet the minimum specifications described in Paragraphs 3.3 through 3.8 of Appendix P of 40 CFR Part 51.

(c)  The excess emissions recorded by the monitoring systems required to be installed under this Rule shall be reported no later than 30 days after the end of the quarter to the Division in the manner described in Paragraphs 4 and 5.1 through 5.3.3 of Appendix P of 40 CFR Part 51 except that a six-minute time period is deemed as an appropriate alternative opacity averaging period as described in Paragraph 4.2 of Appendix P of 40 CFR Part 51.  The owner or operators of any sources subject to this Rule that are required to monitor emissions of sulfur dioxide or nitrogen oxides under any other state or federal rule with continuous emission monitoring systems shall monitor compliance with the sulfur dioxide emission standard in Rule .0516 of this Subchapter and the nitrogen oxide emission standard in Rule .0519 or Section .1400 of this Subchapter with a continuous emission monitoring system. Compliance with sulfur dioxide and nitrogen oxide emission standards are determined by averaging hourly continuous emission monitoring system values over a 24-hour block period beginning at midnight. To compute the 24-hour block average, the average hourly values are summed, and the sum is divided by 24. A minimum of four data points, equally spaced, is required to determine a valid hour value unless the continuous emission monitoring system is installed to meet the provisions of 40 CFR Part 75. If a continuous emission monitoring system is installed to meet the provisions of 40 CFR Part 75, the minimum number of data points are determined by 40 CFR Part 75.

(d)  For emissions of sulfur dioxide, fuel analysis may be used in place of a continuous emissions monitoring system if the source is not required to monitor emissions of sulfur dioxide using a continuous emissions monitoring system under another state or federal rule. If fuel analysis is used as an alternative method to determine emissions of sulfur dioxide, the test methods described in Section .2600 of this Subchapter shall be used except that gross or composite samples, gross caloric value, moisture content, and sulfur content shall be determined per shipment. Alternatively, gross or composite samples, gross caloric value, moisture content, and sulfur content may be determined sampling the fuel as fired if the owner or operator demonstrates to the Director that sampling as fired provides a more accurate estimation of sulfur dioxide emissions than sampling each shipment. If sulfur dioxide emissions are determined sampling fuel as fired, then a fuel sample shall be taken every four hours. These four-hour samples shall be composited into a daily sample, and the daily sample shall be composited into a weekly sample. This weekly sample shall be analyzed using the procedures in Section .2600 of this Subchapter. The sulfur dioxide emission rate shall also be determined using fuel analysis data. Sulfur retention credit shall be granted and used for computing sulfur dioxide emission rates if a source, on a case-by-case basis, quantitatively and empirically demonstrates the sulfur retention.

(e)  Wherever the language of the referenced portion of Appendix P of 40 CFR Part 51 speaks of the "state" or "state plan", the requirements described in Appendix P of 40 CFR Part 51 apply to those sources to which the requirements pertain.

(f)  The owner or operator of the source shall conduct a daily zero and span check of the continuous opacity monitoring system following the manufacturer's recommendations and shall comply with the requirements of Rule .0613 of this Section.

(g)  The owner or operator of the source may request to use a different procedure or methodology than that required by this Rule if one of the conditions identified in 40 CFR Part 51, Appendix P, Section 3.9 exists. The person requesting to use a different procedure or methodology shall submit the request to the Director along with a description of the different procedure or methodology proposed to be used, an explanation of why the procedure or methodology required by this Rule will not work, and a showing that the proposed procedure or methodology is equivalent to the procedure or methodology being replaced. The Director shall approve the use of this procedure or methodology if he finds that one of the conditions identified in 40 CFR Part 51, Appendix P, Section 3.9 exists, that the procedure or methodology required by this Rule will not work, and that the proposed procedure or methodology is equivalent to the procedure or methodology that it will replace.

(h)  The owner or operator of the source shall report to the Director no later than 30 days following the end of the quarter the following information:

(1)           for fuel analysis per shipment:

(A)          the quantity and type of fuels burned,

(B)          the BTU value,

(C)          the sulfur content in percent by weight, and

(D)          the calculated sulfur dioxide emission rates expressed in the same units as the applicable standard.

(2)           for continuous monitoring of emissions:

(A)          the daily calculated sulfur dioxide and nitrogen oxide emission rates expressed in the same units as the applicable standard for each day, and

(B)          other information required under Appendix P of 40 CFR Part 51.

(i)  If emission testing for compliance with the sulfur dioxide emission standard is required, the testing shall be done according to 40 CFR Part 60, Appendix A, Method 6.

(j)  If emission testing for compliance with the nitrogen oxide emission standard is required, the testing shall be done according to 40 CFR Part 60, Appendix A, Method 7.

15A NCAC 02D .0608       OTHER LARGE COAL OR RESIDUAL OIL BURNERS

(a)  The owner or operator of any fuel burning unit shall determine sulfur dioxide emissions into the ambient air if the unit:

(1)           burns coal or residual oil;

(2)           is not required to monitor sulfur dioxide emissions by Rules .0524 or .0606 of this Subchapter;

(3)           has a total heat input of more than 250 million BTU per hour from coal and residual oil; and

(4)           has an annual average capacity factor greater than 30 percent as determined from the three most recent calendar year reports to the Federal Power Commission or as otherwise demonstrated to the Director by the owner or operator. (If the unit has not been in existence for three calendar years, its three-calendar-year average capacity factor shall be determined by estimating its annual capacity factors for enough future years to allow a three-calendar-year average capacity factor to be computed. If this three-calendar-year average capacity factor exceeds 30 percent, the unit shall be monitored. If this three-calendar-year average capacity factor does not exceed 30 percent, the unit need not be monitored.)

(b)  Once the unit is being monitored in accordance with Paragraph (a) of this Rule, it shall continue to be monitored until its most recent three-calendar-year average capacity factor does not exceed 25 percent. Once the unit is not being monitored in accordance with Subparagraph (a) of this Rule, it need not be monitored until its most recent three-calendar-year average capacity factor exceeds 35 percent.

(c)  If units required to be monitored have a common exhaust or if units required to be monitored have a common exhaust with units not required to be monitored, then the common exhaust may be monitored, and the sulfur dioxide emissions need not be apportioned among the units with the common exhaust.

(d)  The owner or operator of the source shall determine sulfur dioxide emissions by:

(1)           an instrument for continuous monitoring and recording of sulfur dioxide emissions, or

(2)           analyses of representative samples of fuels to determine BTU value and percent sulfur content.

(e)  The owner or operators of any sources subject to this Rule that are required to monitor emissions of sulfur dioxide under any other state or federal rule with continuous emission monitoring systems shall monitor compliance with the sulfur dioxide emission standard in Rule .0516 of this Subchapter with a continuous emission monitoring system. Compliance with sulfur dioxide emission standards is determined by averaging hourly continuous emission monitoring system values over a 24-hour block period beginning at midnight. To compute the 24-hour block average, the average hourly values are summed, and the sum is divided by 24. A minimum of four data points, equally spaced, is required to determine a valid hour value unless the continuous emission monitoring system is installed to meet the provisions of 40 CFR Part 75. If a continuous emission monitoring system is installed to meet the provisions of 40 CFR Part 75, the minimum number of data points are determined by 40 CFR Part 75.

(f)  For emissions of sulfur dioxide, fuel analysis may be used in place of a continuous emissions monitoring system if the source is not required to monitor emissions of sulfur dioxide using a continuous emissions monitoring system under another state or federal rule. If fuel analysis is used as an alternative method to determine emissions of sulfur dioxide, then:

(1)           for coal, the test methods described in Section .2600 of this Subchapter shall be used except that gross or composite samples, gross caloric value, moisture content, and sulfur content shall be determined per shipment. Alternatively, gross or composite samples, gross caloric value, moisture content, and sulfur content may be determined sampling the fuel as fired if the owner or operator demonstrates to the Director that sampling as fired provides a more accurate estimation of sulfur dioxide emissions than sampling each shipment. If sulfur dioxide emissions are determined sampling fuel as fired, then a fuel sample shall be taken every four hours. These four-hour samples shall be composited into a daily sample, and the daily sample shall be composited into a weekly sample. This weekly sample shall be analyzed using the procedures in Section .2600 of this Subchapter. The sulfur dioxide emission rate shall also be determined using fuel analysis data. Sulfur retention credit shall be granted and used for computing sulfur dioxide emission rates if a source, on a case-by-case basis, quantitatively and empirically demonstrates the sulfur retention.

(2)           for residual oil, the test methods described in Section .2600 of this Subchapter shall be used except that sulfur content shall be determined per shipment. Alternatively, gross or composite samples, gross caloric value, moisture content, and sulfur content may be determined sampling the fuel as fired if the owner or operator demonstrates to the Director that sampling as fired provides a more accurate estimation of sulfur dioxide emissions than sampling each shipment. If sulfur dioxide emissions are determined sampling fuel as fired, then a fuel sample shall be taken every four hours. These four-hour samples shall be composited into a daily sample, and the daily sample shall be composited into a weekly sample. This weekly sample shall be analyzed using the procedures in Section .2600 of this Subchapter. Residual oil shall be collected in accordance with ASTM D4177 or D4057.

(g)  The owner or operator of the source may request to use a different procedure or methodology than that required by this Rule if one of the conditions identified in 40 CFR Part 51, Appendix P, Section 3.9 exists.  The person requesting to use a different procedure or methodology shall submit the request to the Director along with a description of the different procedure or methodology proposed to be used, an explanation of why the procedure or methodology required by this Rule will not work, and a showing that the proposed procedure or methodology is equivalent to the procedure or methodology being replaced.  The Director shall approve the use of this procedure or methodology if he finds that one of the conditions identified in 40 CFR Part 51, Appendix P, Section 3.9 exists, that the procedure or methodology required by this Rule will not work, and that the proposed procedure or methodology is equivalent to the procedure or methodology that it will replace.

(h)  The owner or operator of the source shall report to the Director no later than 30 days following the end of the quarter the following information:

(1)           for fuel analysis per shipment:

(A)          the quantity and type of fuels burned,

(B)          the BTU value,

(C)          the sulfur content in percent by weight, and

(D)          the calculated sulfur dioxide emission rates expressed in the same units as the applicable standard.

(2)           for continuous monitoring of emissions:

15A NCAC 02D .0614       COMPLIANCE ASSURANCE MONITORING

(a)  General Applicability. With the exception of Paragraph (b) of this Rule, the requirements of this part shall apply to a pollutant‑specific emissions unit at a facility required to obtain permit under 15A NCAC 02Q .0500 if the unit satisfies all of the following criteria:

(1)           The unit is subject to an emission limitation or standard for the applicable regulated air pollutant (or a surrogate thereof), other than an emission limitation or standard that is exempt under Subparagraph (b)(1) of this Rule;

(2)           The unit uses a control device to achieve compliance with any such emission limitation or standard; and

(3)           The unit has potential pre‑control device emissions of the applicable regulated air pollutant that are equal to or greater than 100 percent of the amount, in tons per year, required for a source to be classified as a major source.  For purposes of this Subparagraph, "potential pre‑control device emissions" means the same as "potential to emit," as defined in 15A NCAC 02Q .0103, except that emission reductions achieved by the applicable control device shall not be taken into account.

(b)  Exemptions.

(1)           Exempt emission limitations or standards. The requirements of this Rule shall not apply to any of the following emission limitations or standards:

(A)          emission limitations or standards proposed by the Administrator of the Environmental Protection Agency after November 15, 1990 pursuant to section 111 or 112 of the federal Clean Air Act;

(B)          stratospheric ozone protection requirements under title VI of the federal Clean Air Act;

(C)          Acid Rain Program requirements pursuant to sections 404, 405, 406, 407(a), 407(b), or 410 of the federal Clean Air Act;

(D)          emission limitations or standards or other applicable requirements that apply solely under an emissions trading program approved under the rules of this Subchapter and Subchapter 15A NCAC 02Q and that are incorporated in a permit issued under 15A NCAC 02Q .0500;

(E)           an emissions cap that is approved under the rules of this Subchapter and Subchapter 15A NCAC 02Q and incorporated in a permit issued under 15A NCAC 02Q .0500; or

(F)           emission limitations or standards for which a permit issued under 15A NCAC 02Q .0500 specifies a continuous compliance determination method, as defined in 40 CFR 64.1. (This exemption shall not apply if the applicable compliance method includes an assumed control device emission reduction factor that could be affected by the actual operation and maintenance of the control device (such as a surface coating line controlled by an incinerator for which continuous compliance is determined by calculating emissions on the basis of coating records and an assumed control device efficiency factor based on an initial performance test; in this example, this exemption would apply to the control device and capture system, but not to the remaining elements of the coating line, such as raw material usage).

(2)           Exemption for backup utility power emissions units.  The requirements of this Rule shall not apply to a utility unit, as defined in 40 CFR 72.2, that is municipally‑owned if the owner or operator provides documentation in a permit application submitted under 15A NCAC 02Q .0500 that:

(A)          The utility unit is exempt from all monitoring requirements in 40 CFR Part 75 (including the appendices thereto);

(B)          The utility unit is operated for the sole purpose of providing electricity during periods of peak electrical demand or emergency situations and will be operated consistent with that purpose throughout the permit term. The owner or operator shall provide historical operating data and relevant contractual obligations to document that this criterion is satisfied; and

(C)          The actual emissions from the utility unit, based on the average annual emissions over the last three calendar years of operation (or such shorter time period that is available for units with fewer than three years of operation) are less than 50 tons per year and are expected to remain so.

(c)  For the purposes of this Rule, the definitions in 40 CFR 64.1 shall apply with the following exceptions:

(1)           "Applicable requirement" and "regulated air pollutant" shall have the same definition as in 15A NCAC 02Q .0103.

(2)           "Part 70 or 71 permit application" means an application (including any supplement to a previously submitted application) submitted by the owner or operator to obtain a permit under 15A NCAC 02Q .0500.

(3)           "Part 70 or 71 permit" means a permit issued under 15A NCAC 02Q .0500.

(4)           "Permitting authority" means the Division of Air Quality.

(d)  The owner or operator subject to the requirements of this rule shall comply with these requirements:

(1)           40 CFR 64.3, Monitoring Design Criteria;

(2)           40 CFR 64.4, Submittal Requirements;

(3)           40 CFR 64.5, Deadlines for Submittals;

(4)           40 CFR 64.7, Operation of Approved Monitoring; and

(5)           40 CFR 64.9, Reporting and Recordkeeping Requirements.

(e)  The Division shall follow the procedures and requirements in 40 CFR Part 64.6, Approval of Monitoring, in reviewing and approving or disapproving monitoring plans and programs submitted under this Rule.

(f)  Based on the result of a determination made under 40 CFR 64.7(d)(2), the Director may require the owner or operator to develop and implement a quality improvement plan. If a quality improvement plan is required, the quality improvement plan shall be developed and implemented according to the procedures and requirements of 40 CFR 64.8, Quality Improvement Plan (QIP) Requirements.

(g)  Nothing in this Rule shall:

(1)           excuse the owner or operator of a source from compliance with any existing emission limitation or standard, or any existing monitoring, testing, reporting or recordkeeping requirement that may apply under federal, state, or local law, or any other applicable requirements. The requirements of this Rule shall not be used to justify the approval of monitoring less stringent than the monitoring that is required under another Rule in this Subchapter or Subchapter 15A NCAC 02Q or Title 40 of the CFR and are not intended to establish minimum requirements for the purpose of determining the monitoring to be imposed under another Rule in this Subchapter or Subchapter 15A NCAC 02Q or Title 40 of the CFR. The purpose of this Rule is to require, as part of the issuance of a permit under 15A NCAC 2Q .0500,improved or new monitoring at those emissions units where monitoring requirements do not exist or are inadequate to meet the requirements of this Rule;

(2)           restrict or abrogate the authority of the Division to impose additional or more stringent monitoring, recordkeeping, testing, or reporting requirements on any owner or operator of a source under any provision of this Subchapter or Subchapter 15A NCAC 02Q or the General Statutes;

(3)           restrict or abrogate the authority of the Division to take any enforcement action for any violation of an applicable requirement; or

(4)           restrict the authority of the Administrator of the Environmental Protection Agency or of any person to take action under Section 304 of the federal Clean Air Act as stated under 40 CFR 64.10.

i=1

Where:   Mi = mass of open molding resin or gel coat i used in the past 12 month in an operation, megagrams.

15A NCAC 02D .1105       FACILITY REPORTING, RECORDKEEPING

The Director may require, according to Section .0600 of this Subchapter, the owner or operator of a source subject to this Section to monitor emissions of toxic air pollutants, to maintain records of these emissions, and to report these emissions.  The owner or operator of any toxic air pollutant emission source subject to the requirements of this Section shall comply with the monitoring, recordkeeping, and reporting requirements in Section .0600 of this Subchapter.

15A NCAC 02D .1106       DETERMINATION OF AMBIENT AIR CONCENTRATION

(a)  Modeling shall not be used for enforcement.  Modeling shall be used to determine process operational and air pollution control parameters and emission rates for toxic air pollutants to place in the air quality permit for that facility that will prevent any of the acceptable ambient levels in Rule .1104 of this Section from being exceeded, with such exceptions as may be allowed under 15A NCAC 2Q .0700.  Enforcing these permit stipulations and conditions shall be the mechanism used to ensure that the requirements of Rule .1104 of this Section, with such exceptions as may be allowed by 15A NCAC 2Q .0700, are met.

(b)  The owner or operator of the facility may request the Division to perform a modeling analysis of the facility or provide the analysis himself.  If the owner or operator of the facility requests the Division to perform the modeling analysis, he shall provide emissions rates, stack parameters, and other information that the Division needs to do the modeling.  The data that the owner or operator of the facility provides the Division to use in the model or in deriving the data used in the model shall be the process, operational and air pollution control equipment parameters and emission rates that will be contained in the facility=s permit.  If the Division=s initial review of the modeling request indicates extensive or inappropriate use of state resources or if the Division=s modeling analysis fails to show compliance with the acceptable ambient levels in Rule .1104 of this Section, the modeling demonstration becomes the responsibility of the owner or operator of the facility.

(c)  When the owner or operator of the facility is responsible for providing the modeling demonstration and the data used in the modeling, the owner or operator of the facility shall use in the model or in deriving data used in the model the process operational and air pollution control equipment parameters and emission rates that will be contained in his permit.  Sources that are not required to be included in the model will not be included in the permit to emit toxic air pollutants.

(d)  For the following pollutants, modeled emission rates shall be based on the highest emissions occurring in any single 15 minute period.  The resultant modeled 1-hour concentrations shall then be compared to the applicable 1-hour acceptable ambient levels to determine compliance.  These pollutants are:

(1)           acetaldehyde (75-07-0)

(2)           acetic acid (64-19-7)

(3)           acrolein (107-02-8)

(4)           ammonia (7664-41-7)

(5)           bromine (7726-95-6)

(6)           chlorine (7782-50-5)

(7)           formaldehyde (50-00-0)

(8)           hydrogen chloride (7647-01-0)

(9)           hydrogen fluoride (7664-39-3)

(10)         nitric acid (7697-37-2)

(e)  The owner or operator of the facility and the Division may use any model allowed by 40 CFR 51.166(l) provided that the model is appropriate for the facility being modeled.  The owner or operator or the Division may use a model other than one allowed by 40 CFR 51.166(l) provided that the Director determines that the model is equivalent to the model allowed by 40 CFR 51.166(l).  Regardless of model used, the owner or operator and the Division shall model for cavity effects and shall comply with the modeling requirements for stack height set out in Rule .0533 of this Subchapter.

(f)  Ambient air concentrations are to be evaluated for annual periods over a calendar year, for 24-hour periods from midnight to midnight, and for one-hour periods beginning on the hour.

(g)  The owner or operator of the facility shall identify each toxic air pollutant emitted and its corresponding emission rate using mass balancing analysis, source testing, or other methods that the Director may approve as providing an equivalently accurate estimate of the emission rate.

(h)  The owner or operator of the facility shall submit a modeling plan to the Director and shall have received approval of that plan from the before submitting a modeling demonstration to the Director.  The modeling plan shall include:

(1)           a diagram of the plant site, including locations of all stacks and associated buildings;

(2)           on-site building dimensions;

(3)           a diagram showing property boundaries, including a scale, key and north indicator;

(4)           the location of the site on a United States Geological Survey (USGS) map;

(5)           discussion of good engineering stack height and building wake effects for each stack;

(6)           discussion of cavity calculations, impact on rolling and complex terrain, building wake effects, and urban/rural considerations;

(7)           discussion of reasons for model selection;

(8)           discussion of meteorological data to be used;

(9)           discussion of sources emitting the pollutant that are not to be included in the model with an explanation of why they are being excluded (i.e. why the source will not affect the modeling analysis); and

(10)         any other pertinent information.

15A NCAC 02D .1107       MULTIPLE FACILITIES

(a)  If an acceptable ambient level in Rule .1104 of this Section is exceeded because of emissions of two or more facilities and if public exposure is such that the commission has evidence that human health may be adversely affected, then the Commission shall require the subject facilities to apply addition controls or to otherwise reduce emissions.  The type of evidence that the Commission shall consider shall include one or more of the following:

(1)           emission inventory,

(2)           ambient monitoring,

(3)           modeling, or

(4)           epidemiological study.

(b)  The allocation of the additional reductions shall be based on the relative contributions to the pollutant concentrations unless the owners or operators agree otherwise.

(c)  The owner or operator of a facility shall not be required to conduct the multi-facility ambient impact analysis described in Paragraph (a) of this Rule.  This type of analysis shall be done by the Division of  Air Quality.  In performing its analysis, the Division shall:

(1)           develop a modeling plan that includes the elements set out in Paragraph (f) of Rule .1106 of this Section;

(2)           use for the source modeling parameters, the modeling parameters used by the owner or operator of the source in his modeling demonstration, or if a modeling demonstration has not been done or if a needed parameter has not been used in the modeling demonstration, parameters contained in, or derived from data contained in, the source's permit;

(3)           use a model allowed by Paragraph (c) of Rule .1106 of this Section;

(4)           model for cavity effects and comply with the modeling requirements for stack height set out in Rule .0533 of this Section;

(5)           use the time periods required by Paragraph (d) of Rule .1106 of this Section; and

(6)           only consider impacts of a facility=s emissions beyond the premises of that facility.

(15)         "Research and development activities" means activities conducted at a research or laboratory facility whose primary purpose is to conduct research and development into new processes and products, where such source is operated under the close supervision of technically trained personnel and is not engaged in the manufacture of products for sale or exchange for commercial profit, except in a de minimis manner.

(16)         "Similar source" means a stationary source or process that has comparable emissions and is structurally similar in design and capacity to a constructed or reconstructed major source such that the source could be controlled using the same control technology.

(d)  Principles of MACT determinations.  The following general principles shall be used to make a case-by-case MACT determination concerning construction or reconstruction of a major source under this Rule:

(1)           The MACT emission limitation or MACT requirements recommended by the applicant and approved by the Division shall not be less stringent than the emission control that is achieved in practice by the best controlled similar source, as determined by the Division.

(2)           Based upon available information, the MACT emission limitation and control technology (including any requirements under Subparagraph (3) of this Paragraph) recommended by the applicant and approved by the Division shall achieve the maximum degree of reduction in emissions of HAP that can be achieved by utilizing those control technologies that can be identified from the available information, taking into consideration the costs of achieving such emission reduction and any non-air quality health and environmental impacts and energy requirements associated with the emission reduction.

(3)           The owner or operator  may recommend a specific design, equipment, work practice, or operational standard, or a combination thereof, and the Director may approve such a standard if the Division specifically determines that it is not feasible to prescribe or enforce an emission limitation under the criteria set forth in Section 112(h)(2) of the federal Clean Air Act.

(4)           If the EPA has either proposed a relevant emission standard pursuant to Section 112(d) or 112(h) of the federal Clean Air Act or adopted a presumptive MACT determination for the source category that includes the constructed or reconstructed major source, then the MACT requirements applied to the constructed or reconstructed major source shall have considered those MACT emission limitations and requirements of the proposed standard or presumptive MACT determination.

(e)  Effective date of MACT determination. The effective date of a MACT determination shall be the date of issuance of a permit under procedures of 15A NCAC 2Q .0300 or .0500 incorporating a MACT determination.

(f)  Compliance date.  On and after the date of start-up, a constructed or reconstructed major source that is subject to the requirements of this Rule shall be in compliance with all applicable requirements specified in the MACT determination.

(g)  Compliance with MACT determinations.   The owner or operator of a constructed or reconstructed major source that:

(1)           is subject to a MACT determination shall comply with all requirements set forth in the permit issued under 15A NCAC 2Q .0300 or .0500, including any MACT emission limitation or MACT work practice standard, and any notification, operation and maintenance, performance testing, monitoring, reporting, and recordkeeping requirements; or

(2)           has obtained a MACT determination shall be deemed to be in compliance with Section 112(g)(2)(B) of the federal Clean Air Act only to the extent that the constructed or reconstructed major source is in compliance with all requirements set forth in the permit issued under 15A NCAC 2Q .0300 or .0500.  Any violation of such requirements by the owner of operator shall be deemed by the Division and by EPA to be a violation of the prohibition on construction or reconstruction in Section 112(g)(2)(B) of the federal Clean Air Act for whatever period the owner or operator is determined to be in violation of such requirements, and shall subject the owner or operator to appropriate enforcement action under the General Statutes and the federal Clean Air Act.

(h)  Requirements for constructed or reconstructed major sources subject to a subsequently promulgated MACT standard or MACT requirement. If EPA promulgates an emission standard under Section 112(d) or 112(h) of the federal Clean Air Act or the Division issues a determination under Rule .1109 of this Section that is applicable to a stationary source or group of sources that would be deemed to be a constructed or reconstructed major source under this Rule:

(1)           before the date that the owner or operator has obtained a final and legally effective MACT determination under 15A NCAC 2Q .0300 or .0500, the owner or operator of the source(s) shall comply with the promulgated standard or determination rather than any MACT determination under this Rule by the compliance date in the promulgated standard; or

(2)           after the source has been subject to a prior case-by-case MACT under this Rule, and the owner or operator obtained a final and legally effective case-by-case MACT determination prior to the promulgation date of such emission standard, the Division shall (if the initial permit has not yet been issued under 15A NCAC 2Q .0500) issue an initial permit that incorporates the emission standard or determination, or shall (if the initial permit has been issued under 15A NCAC 2Q .0500) revise the permit according to the reopening procedures in 15A NCAC 2Q .0517, Reopening for Cause, whichever is relevant, to incorporate the emission standard or determination.

(i)  Compliance with subsequent 112(d), 112(h),or 112(j) standards.  EPA may include in the emission standard established under Section 112(d) or 112(h) of the federal Clean Air Act a specific compliance date for those sources that have obtained a final and legally effective MACT determination under this Rule and that have submitted the information required by 40 CFR 63.43 to EPA before the close of the public comment period for the standard established under section 112(d) of the federal Clean Air Act.  Such date shall assure that the owner or operator shall comply with the promulgated standard as expeditiously as practicable, but not longer than eight years after such standard is promulgated.  In that event, the Division shall incorporate the applicable compliance date in the permit issued under 15A NCAC 2Q .0500.  If no compliance date has been established in the promulgated 112(d) or 112(h) standard or determination under Rule .1109 of this Section, for those sources that have obtained a final and legally effective MACT determination under this Rule, then the Director shall establish a compliance date in the permit that assures that the owner or operator shall comply with the promulgated standard or determination as expeditiously as practicable, but not longer than eight years after such standard is promulgated or a determination is made under Rule .1109 of this Section.

(j)  Revision of permit to incorporate less stringent control.  Notwithstanding the requirements of Paragraph (h) of this Rule, if the Administrator of EPA promulgates an emission standard under Section 112(d) or Section 112(h) of the federal Clean Air Act or the Division issues a determination under Rule .1109 of this Section that is applicable to a stationary source or group of sources that was deemed to be a constructed or reconstructed major source under this Rule and that is the subject of a prior case-by-case MACT determination pursuant to 40 CFR 63.43, and the level of control required by the emission standard issued under Section 112(d) or 112(h) or the determination issued under Rule .1109 of this Section is less stringent than the level of control required by any emission limitation or standard in the prior MACT determination, the Division is not required to incorporate any less stringent terms of the promulgated standard in the permit issued under 15A NCAC 2Q .0500 applicable to such source(s) and may consider any more stringent provisions of the prior MACT determination to be applicable legal requirements when issuing or revising such an operating permit.
