15A NCAC 02T .0114      WASTEWATER DESIGN FLOW RATES

(a)  This Rule shall be used to determine wastewater flow rates for all systems governed by this Subchapter unless alternate criteria are provided by a program-specific rule or for flow used for the purposes of 15A NCAC 02H .0105. Higher flow rates shall be required where usage and occupancy are atypical, including those in Paragraph (e) of this Rule. Wastewater flow calculations shall take hours of operation and anticipated maximum occupancies and usage into account when calculating peak flows for design.

(b)  In determining the volume of sewage from dwelling units, the flow rate shall be 120 gallons per day per bedroom. The minimum volume of sewage from each dwelling unit shall be 240 gallons per day and each additional bedroom above two bedrooms shall increase the volume by 120 gallons per day. Each bedroom or any other room or addition that can function as a bedroom shall be considered a bedroom for design purposes. When the occupancy of a dwelling unit exceeds two persons per bedroom, the volume of sewage shall be determined by the maximum occupancy at a rate of 60 gallons per person per day.

(c)  The following table shall be used to determine the minimum allowable design daily flow of wastewater facilities. Design flow rates for establishments not identified below shall be determined using available flow data, water‑using fixtures, occupancy or operation patterns, and other measured data.

(f)  An adjusted daily sewage flow design rate shall be granted for permitted but not yet tributary connections and future connections tributary to the system upon showing that the capacity of a sewage system is adequate to meet actual daily wastewater flows from a facility included in Paragraph (b) or (c) of this Rule without causing flow violations at the receiving wastewater treatment plant or capacity-related sanitary sewer overflows within the collection system as follows:

(1)           Documented, representative data from that facility or a comparable facility shall be submitted by an authorized signing official in accordance with Rule .0106 of this Section to the Division for all flow reduction requests, as follows:

(A)          dates of flow meter calibrations during the time frame evaluated and indication if any adjustments were necessary;

(B)          a breakdown of the type of connections (e.g. two bedroom units, three bedroom units) and number of customers for each month of submitted data as applicable. Identification of any non-residential connections including subdivision clubhouses and pools, restaurants, schools, churches and businesses. For each non-residential connection, information identified in Paragraph (c) of this Rule (e.g. 200 seat church, 40 seat restaurant, 35 person pool bathhouse);

(C)          a letter of agreement from the owner or an official, meeting the criteria of Rule .0106 of this Section, of the receiving collection system or treatment works accepting the wastewater and agreeing with the adjusted design rate;

(D)          age of the collection system;

(E)           analysis of inflow and infiltration within the collection system or receiving treatment plant, as applicable;

(F)           if a dedicated wastewater treatment plant serves the specific area and is representative of the residential wastewater usage, at least the 12 most recent consecutive monthly average wastewater flow readings and the daily total wastewater flow readings for the highest average wastewater flow month per customers, as reported to the Division;

(G)          if daily data from a wastewater treatment plant cannot be used or is not representative of the project area: 12 months worth of monthly average wastewater flows from the receiving treatment plant shall be evaluated to determine the peak sewage month. Daily wastewater flows shall then be taken from a flow meter installed at the most downstream point of the collection area for the peak month selected that is representative of the project area. Justification for the selected placement of the flow meter shall also be provided; and

(H)          an estimated design daily sewage flow rate shall be determined by calculating the numerical average of the top three daily readings for the highest average flow month. The calculations shall also account for seasonal variations, excessive inflow and infiltration, age and suspected meter reading and recording errors.

(2)           The Division shall evaluate all data submitted but shall also consider other factors in granting, with or without adjustment, or denying a flow reduction request including: applicable weather conditions during the data period (i.e. rainy or drought), other historical monitoring data for the particular facility or other similar facilities available to the Division, the general accuracy of monitoring reports and flow meter readings, and facility usage, such as whether the facility is in a resort area.

(3)           Flow increases shall be required if the calculations required by Subparagraph (f)(1) of this Rule yield design flows higher than that specified in Paragraphs (b) or (c) of this Rule.

(4)           The permittee shall retain the letter of any approved adjusted daily design flow rate for the life of the facility and shall transfer such letter to a future permittee.

Readopted Eff. September 1, 2018.

 

15A NCAC 02T .0302      DEFINITIONS

(a)  The following definitions shall apply in this Section:

(1)           "Alternative sewer system" means any sewer system or collection system other than a gravity system or standard pump station and force main. These include pressure sewer systems, septic tank with effluent pump (STEP) sewer systems, vacuum sewer system, and small diameter variable grade gravity sewers.

(2)           "Building" means any structure occupied or intended for supporting or sheltering any occupancy.

(3)           "Building drain" means that part of the lowest piping of a drainage system that receives the discharge from soil, waste, and other drainage pipes that extends 10 feet beyond the walls of the building and conveys the drainage to the building sewer.

(4)           "Building sewer" means that part of the drainage system that extends from the end of the building drain and conveys the discharge from a single building to a public gravity sewer, private gravity sewer, individual sewage disposal system, or other point of disposal.

(5)           "Fast-track" means a permitting process whereby a professional engineer certifies that a sewer design and associated construction documents conform to all applicable sewer related rules and design criteria.

(6)           "Pressure sewer system" means an interdependent system of grinder pump stations, typically for residences, serving individual wastewater connections for single buildings that share a pressure pipe with a diameter of 1.5 inches through 6 inches. Duplex or greater pump stations connected to a common pressure pipe that can operate both independently and simultaneously with other pump stations while maintaining operation of the system within the operating constraints shall be excluded from the definition of a pressure sewer system.

(7)           "Private sewer" means any part of a sewer system that collects wastewater from one building and crosses another property or travels along a street right of way or from more than one building and is not a public sewer.

(8)           "Public sewer" means a sewer located in a dedicated public street, roadway, or dedicated public right‑of‑way or easement that is owned or operated by any municipality, county, water or sewer district, or any other political subdivision of the state authorized to construct or operate a sewer system.

(9)           "Sewer system" means pipelines or conduits, pumping stations including lift stations and grinder stations, alternative systems, and appurtenant appliances used for conducting wastewater to a point of ultimate treatment and disposal.

(10)         "Small diameter, variable grade gravity sewer system" means a system of wastewater collection using an interceptor tank to remove solids and grease from the waste stream. Flow is transferred to the central gravity system in the public right-of-way by gravity or effluent pumps. With venting and design, inflected gradients may also be accommodated.

(11)         "Septic tank with effluent pump (STEP) system" means a pressure sewer system in which the individual grinder pump is replaced with a septic tank and an effluent pump either in the second chamber of the septic tank or in a separate pump tank that follows the septic tank.

(12)         "Vacuum sewer system" means a mechanized system of wastewater collection using differential air pressure to move the wastewater. Centralized stations provide the vacuum with valve pits providing the collection point from the source and also the inlet air required to move the wastewater. In conjunction with the vacuum pumps, a standard non-vacuum pump station and force main is used to transport the wastewater from the vacuum tanks to a gravity sewer or ultimate point of treatment and disposal.

15A NCAC 02T .1505      DESIGN CRITERIA

(a)  Land Application of Soils Containing Petroleum Products at Minimum Rates. Petroleum-contaminated soils shall be incorporated into the native soils of the receiver site immediately upon application. Subsequent application of petroleum-contaminated soils onto the same receiver site shall not occur for at least 18 months from the date of the most recent application of petroleum-contaminated soils and shall cause the receiver site to be reclassified as a "dedicated site" unless the permittee or applicant can demonstrate, through soil sampling and contaminant analytical procedures pursuant to 15A NCAC 02H .0800, that the petroleum contaminant level in the upper eight inches of the receiver site soils is below either the soil-to-groundwater contaminant concentrations or the residential maximum soil contaminant concentrations established by the Department pursuant to 15A NCAC 02L .0411, whichever is lower.

(b)  Land Application of Soil Containing Petroleum Products at Conventional Rates. Land application of soils containing petroleum products at an application thickness greater than one inch shall require fertilization, liming, and aeration of the mixture of native and petroleum-contaminated soils. Application thickness shall be based upon the nature of the receiver site soils, depth to the seasonal high water table, the intended cover crop, and the source of contamination. Operation of the land application program shall not result in contravention of groundwater or surface water standards. Subsequent application of petroleum-contaminated soils onto the same receiver site shall not occur for at least 18 months from the date of the most recent application of petroleum-contaminated soils and shall cause the receiver site to be reclassified as a "dedicated site" unless the permittee or applicant can demonstrate, through soil sampling and contaminant analytical procedures pursuant to 15A NCAC 02H .0800, that the petroleum contaminant level in the upper eight inches of the receiver site soils is below either the soil-to-groundwater contaminant concentrations or the residential maximum soil contaminant concentrations established by the Department pursuant to 15A NCAC 02L .0411, whichever is lower.

(c)  Disposal of Soils Containing Petroleum Products at Dedicated Land Application Sites. Subsequent applications of petroleum-contaminated soils at dedicated sites shall not recur until such time as it can be demonstrated that additional applications of contaminated soils will not result in the contravention of any groundwater or surface water standards.

(d)  Containment, Treatment and Containment, and Use of Contaminated Soil.

(1)           A containment structure designed to bioremediate or volatilize contaminated soil shall be constructed of either a synthetic liner of at least 30 mils thickness or of a one-foot-thick liner of natural material compacted to at least 95 percent standard proctor dry density and with a permeability of less than 1 x 10-7 cm/sec.

(2)           The bottom of the containment structure shall be at least three feet above the seasonal high water table or bedrock.

(3)           A leachate collection system shall be installed in order to prevent runoff from the contaminated soils within the containment structure, or a cover shall be provided to avoid accumulation of stormwater within the containment structure.

(4)           The containment structure shall be compatible with the chemical and physical properties of the contaminants involved.

15A NCAC 02T .1605      DESIGN CRITERIA

(a)  The infiltration galleries or injection wells shall be designed such that the infiltration galleries or injection wells will not cause or contribute to any of the following:

(1)           the migration of contaminants into previously uncontaminated areas;

(2)           a violation of the groundwater standards at the compliance boundary if discharge is within the compliance boundary of the disposal facility; or

(3)           a violation of the groundwater standards at the point of the discharge if discharge is not within the compliance boundary of the disposal facility.

(b)  There shall be provisions in the operating plan to ensure the quality of the treated effluent and hydraulic control of the system at all times when any portion of the system ceases to function, such as standby power capability, complete system-off status, or duplicity of system components.

(c)  The infiltration galleries and injection wells shall be designed to include elevation protection of two feet above the 100-year flood elevation.

(d)  Flow equalization of 25 percent of the facility's permitted hydraulic capacity shall be provided for facilities with fluctuations in influent flow that may adversely affect the performance of the system.
