Subchapter B - SOLID WASTE MANAGEMENT
Section .1600 - REQUIREMENTS FOR MUNICIPAL SOLID WASTE LANDFILL FACILITIES (MSWLFS)
Section 13B .1619 - FACILITY PLAN
Universal Citation: 15A NC Admin Code 13B .1619
Current through Register Vol. 38, No. 18, March 15, 2024
(a) Purpose. A permit applicant shall prepare a facility plan that meets the requirements of this Rule.
(b) Scope.
(1) The facility plan shall define the
comprehensive development of the property proposed for permit or described in
the permit of an existing facility. The plan shall include a set of drawings
and a report that present the long-term, general design concepts related to
construction, operation, and closure of the MSWLF unit(s), including leachate
management. The scope of the plan shall span the active life of the MSWLF
unit(s). Additional solid waste management facilities located at the MSWLF
facility shall be identified in the plan and shall meet the requirements of
this Subchapter. The facility plan shall define the waste stream proposed for
management at the MSWLF facility. If different types of landfill units or
non-disposal activities are included in the facility design, the plan shall
describe general waste acceptance procedures.
(2) The areal limits of the MSWLF unit(s),
total capacity of the MSWLF unit(s), and the proposed waste stream shall be
consistent with the Division's approval in accordance with Rule .1618(a)(1) of
this Section for a new facility.
(c) Use of Terms. The terminology used in describing areas of the MSWLF unit shall be defined as follows and shall be used consistently throughout a permit application.
(1) "phase" means an area constructed with a
base liner system that describes approximately five years of operating
capacity. An applicant may request a permit to construct for any number of
phases up to the entire extent of the disposal boundary for the
life-of-site.
(2) "cell" means a
subdivision of a phase which describes modular or partial
construction.
(3) "subcell" means a
subdivision of a cell which describes leachate and stormwater management for
active or inactive areas of the constructed MSWLF.
(d) Facility Drawings. The facility plan shall include the following drawings:
(1) Site
Development. The two drawings that plot site development shall be prepared on
topographic maps representative of existing site conditions; and the maps shall
locate or delineate the physical features referenced in Rule .1622 of this
Section and shall incorporate a survey locating all property boundaries for the
proposed landfill facility certified by a licensed professional land surveyor,
if required by G.S. 89C.
(A) Landfill units
and leachate facilities. This drawing shall delineate the areal limits of all
landfill units and leachate facilities and incorporate the buffer requirements
set forth in Rule .1624(b)(3) of this Section and the maximum allowed disposal
area set forth in Rule .1624(b)(17) of this Section.
(B) All facilities. This drawing shall locate
all solid waste management facilities and facility infrastructure, including
landfill units and leachate facilities.
(2) Landfill Construction. All on-site
grading activities related to the construction and operation of the MSWLF
unit(s) shall be illustrated in facility drawings which:
(A) delineate the limits of grading,
including borrow and stockpile areas;
(B) define phases of development in
increments of five years of operating capacity, up to the entire extent of the
disposal boundary for the life-of-site;
(C) propose base grades for the MSWLF
unit(s);
(D) delineate the location
of access roads, sedimentation basins, leachate pipeline and storage or
treatment facilities and other structures related to the operation of the MSWLF
unit; and
(E) propose final
contours for the MSWLF unit(s) and facility features for closure that comply
with the maximum allowed height requirement of Rule .1624(b)(17) of this
Section.
(3) Landfill
Operation. The following information related to the long-term operation of the
MSWLF units shall be included in facility drawings:
(A) general grade and flow direction for the
drainage layer component of the leachate collection system;
(B) size, location, and general grade for the
leachate piping system, including on-site pipelines to leachate management
facilities;
(C) proposed
transitional contours for each phase of development, including operational
grades for existing phase(s) and construction grading for the new phase;
and
(D) if included in the design,
stormwater segregation features and details for inactive landfill
subcells.
(e) Facility Report. The facility plan shall include the following information:
(1) Waste stream. A discussion of the
characteristics of the wastes received at the facility and facility specific
management plans shall incorporate:
(A) the
types of waste specified for disposal;
(B) average monthly disposal rates and
estimated variance;
(C) the area
served by the facility;
(D)
procedures for segregated management at different on-site facilities;
and
(E) equipment requirements for
operation of the MSWLF unit.
(2) Landfill Capacity. An analysis of
landfill capacity and soil resources shall be performed.
(A) The data and assumptions used in the
analysis shall be included with the facility drawings and disposal rates
specified in the facility plan; and representative of operational requirements
and conditions.
(B) The conclusions
shall provide accurate volumetric estimates of total operating capacity that
does not exceed the maximum allowed capacity defined in Rule .1624(b)(17) of
this Section; operating capacity for each stage of development; in-place ratio
of waste to soil; available soil resources from on-site or specific off-site
sources; required quantities of soil for landfill construction, operation, and
closure; and the estimated operating life of all MSWLF units in
years.
(3) Containment
and environmental control systems. A general description of the systems
designed for proper landfill operation, system components, and corresponding
functions shall be provided.
(4)
Leachate Management. An analysis of the leachate management requirements and
plans for the MSWLF facility shall incorporate the information required under
this Subparagraph.
(A) The performance of and
design concepts for the leachate collection system within active areas of the
MSWLF unit and any storm water segregation included in the engineering design
shall be described.
(B) Normal
operating conditions. Normal operating conditions shall be defined and shall
consider surge volumes generated by storm events; and average monthly values
for leachate generation representative of the landfill's environment and
operation using empirically derived estimates, or for landfill expansions,
actual leachate generation data from the existing landfill.
(C) Leachate management system. A description
of the leachate management system components and their engineered function
shall be provided, and shall include leachate pipeline operating capacity;
capacity of the storage and if applicable, the treatment facilities; and final
disposal plans and applicable discharge limits, including documented prior
approval of the waste water treatment plant which may be designated in the
plan.
(D) A contingency plan shall
be prepared for storm surges or other considerations exceeding design
parameters for the storage or treatment facilities.
(5) Special engineering features. A
description of any special engineering features specific to the landfill that
the applicant is proposing shall be provided.
(6) Traffic study. A traffic study and NC
Department of Transportation certification shall be prepared as required by
G.S.
130A-295.5 and in accordance with the
effective date and applicability set forth in S.L. 2007-550, s.
8.(b).
(7) Study of Environmental
Impacts. A study of environmental impacts shall be conducted as required by
