15A NCAC 02T .0604 APPLICATION SUBMITTAL
(a) The requirements in this Rule apply to all new and expanding facilities, as applicable.
(b) Soils Report. A soil evaluation of the disposal site shall be provided to the Division by the applicant in a report that includes the following. If required by G.S. 89F, a soil scientist shall prepare this evaluation:
[Note: The North Carolina Board for Licensing of Soil Scientists has determined, via letter dated December 1, 2005, that preparation of soils reports pursuant to this Paragraph constitutes practicing soil science under G.S. 89F.]
(1) Field description of soil profile, based on examinations of excavation pits and auger borings, within seven feet of land surface or to bedrock describing the following parameters by individual diagnostic horizons:
(A) thickness of the horizon;
(C) color and other diagnostic features;
(E) internal drainage;
(F) depth, thickness, and type of restrictive horizon(s); and
(G) presence or absence and depth of evidence of any seasonal high water table.
Applicants may be required to dig pits when necessary for proper evaluation of the soils at the site.
(2) Recommendations concerning loading rates of liquids, solids, other wastewater constituents and amendments. Annual hydraulic loading rates shall be based on in-situ measurement of saturated hydraulic conductivity in the most restrictive horizon for each soil mapping unit. Maximum irrigation precipitation rates shall be provided for each soil mapping unit.
(3) A soil map delineating soil mapping units within each land application site and showing all physical features, location of pits and auger borings, legends, scale, and a north arrow.
(4) A representative soils analysis (i.e., Standard Soil Fertility Analysis) conducted on each land application site. The Standard Soil Fertility Analysis shall include the following parameters:
(B) base saturation (by calculation),
(D) cation exchange capacity,
(F) exchangeable sodium percentage (by calculation),
(I) percent humic matter,
(M) sodium, and
(c) Engineering design documents. If required by G.S. 89C, a professional engineer shall prepare these documents. The following documents shall be provided to the Division by the applicant:
[Note: The North Carolina Board of Examiners for Engineers and Surveyors has determined, via letter dated December 1, 2005, that preparation of engineering design documents pursuant to this Paragraph constitutes practicing engineering under G.S. 89C.]
(1) engineering plans for the entire system, including treatment, storage, application, and disposal facilities and equipment except those previously permitted unless those previously permitted are directly tied into the new units or are critical to the understanding of the complete process;
(2) specifications describing materials to be used, methods of construction, and means for ensuring quality and integrity of the finished product including leakage testing; and
(3) engineering calculations including hydraulic and pollutant loading for each treatment unit, treatment unit sizing criteria, hydraulic profile of the treatment system, total dynamic head and system curve analysis for each pump, buoyancy calculations, and irrigation design.
(d) Site plans. If required by G.S. 89C, a professional land surveyor shall provide location information on boundaries and physical features not under the purview of other licensed professions. Site plans or maps shall be provided to the Division by the applicant depicting the location, orientation and relationship of facility components including:
[Note: The North Carolina Board of Examiners for Engineers and Surveyors has determined, via letter dated December 1, 2005, that locating boundaries and physical features, not under the purview of other licensed professions, on maps pursuant to this Paragraph constitutes practicing surveying under G.S. 89C.]
(1) a scaled map of the site, with topographic contour intervals not exceeding two feet and showing all facility-related structures and fences within the treatment, storage and disposal areas, and soil mapping units shown on all disposal sites;
(2) the location of all wells (including usage and construction details if available), streams (ephemeral, intermittent, and perennial), springs, lakes, ponds, and other surface drainage features within 500 feet of all waste treatment, storage, and disposal site(s) and delineation of the review and compliance boundaries;
(3) setbacks as required by Rule .0606 of this Subchapter; and
(4) site property boundaries within 500 feet of all waste treatment, storage, and disposal site(s).
(e) Property Ownership Documentation shall be provided to the Division consisting of:
(1) legal documentation of ownership (i.e., contract, deed or article of incorporation);
(2) written notarized intent to purchase agreement signed by both parties, accompanied by a plat or survey map; or
(3) written notarized lease agreement signed by both parties, specifically indicating the intended use of the property, as well as a plat or survey map. Lease agreements shall adhere to the requirements of 15A NCAC 02L .0107.
(f) An Operation and Maintenance Plan addressing routine inspections, maintenance schedules, troubleshooting and a layman's explanation about the wastewater treatment and irrigation disposal systems shall be submitted to the Division by the applicant.
(g) A letter from the local County Health Department denying the site for all subsurface systems shall be submitted to the Division by the applicant.
(h) A notarized Operation and Maintenance Agreement shall be submitted to the Division by the applicant.
