Current through Register Vol. 39, No. 6, September 16, 2024
(a) The
requirements in this Rule shall apply to all new and expanding
facilities.
(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:
(1) a field description of the 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) the
thickness of the horizon;
(B) the
texture;
(C) the color and other
diagnostic features;
(D) the
structure;
(E) the internal
drainage;
(F) the depth, thickness,
and type of restrictive horizon; and
(G) the 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
field-delineated 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. The legends shall also include
dominant soil series name and family or higher taxonomic class for each soil
mapping unit; and
(4) a Standard
Soil Fertility Analysis conducted on each land application site. The Standard
Soil Fertility Analysis shall include the following parameters:
(A) acidity;
(B) base saturation (by
calculation);
(C)
calcium;
(D) cation exchange
capacity;
(E) copper;
(F) exchangeable sodium percentage (by
calculation);
(G)
magnesium;
(H) manganese;
(I) percent humic matter;
(J) pH;
(K) phosphorus;
(L) potassium;
(M) sodium; and
(N) zinc.
[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
pursuant to G.S. 89F.]
(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:
(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 necessary to understanding 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.
[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 pursuant to G.S. 89C.]
(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:
(1) a scaled map of the
site, with topographic contour intervals not exceeding 10 feet or 25 percent of
total site relief, showing:
(A) all
facility-related structures and fences within the treatment, storage, and
disposal areas; and
(B) soil
mapping units on all disposal sites;
(2) the location of each of the following
that are located within 500 feet of a waste treatment, storage, or disposal
site, including a delineation of their review and compliance boundaries:
(A) wells, including usage and construction
details if available;
(B)
ephemeral, intermittent, and perennial streams;
(C) springs;
(D) lakes;
(E) ponds; and
(F) other surface drainage
features;
(3) setbacks
as required by Rule .0606 of this Section; and
(4) site property boundaries within 500 feet
of all waste treatment, storage, and disposal sites.
[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 pursuant to G.S. 89C.]
(e) Property Ownership Documentation shall be
provided to the Division consisting of:
(1)
legal documentation of ownership, such as a contract, deed, or article of
incorporation;
(2) an agreement of
an intent to purchase the property that is written, notarized, and signed by
both parties, accompanied by a plat or survey map; or
(3) an agreement to lease the property that
is written, notarized, and signed by both parties, indicating the intended use
of the property, accompanied by 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 properly executed Operation and Maintenance Agreement shall be submitted to
the Division by the applicant.
