15A NCAC 13B .0537      FACILITY PLAN FOR C&DLFs

(a)  Purpose. A permit applicant shall prepare a facility plan which meets the requirements of this Rule.

(b)  Scope.

(1)           The facility plan shall define the comprehensive development of the property proposed for a 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 C&DLF unit(s). The scope of the plan shall span the active life of the unit(s). Additional solid waste management activities located at the C&DLF 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 C&DLF 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 C&DLF unit(s), total capacity of the C&DLF unit(s), and the proposed waste stream shall be consistent with the Division's approval in accordance with Rule .0536(a)(1) of this Section for a new facility.

(c)  Use of Terms. The terminology used in describing areas of the C&DLF unit(s) shall be defined as follows and shall be used consistently throughout a permit application:

(1)           "phase" means an area constructed 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, if required, for active or inactive areas of the constructed C&DLF.

(d)  Facility Drawings. The facility plan shall include the following drawings:

(1)           Site Development. The drawings that plot site development shall be prepared on topographic maps representative of existing site conditions; and the maps shall locate or delineate the following:

(A)          delineate the areal limits of all landfill units, and incorporate the buffer requirements set forth in Rule .0540(1) of this Section;

(B)          locate all solid waste management facilities and facility infrastructure, including landfill units;

(C)          delineate the areal limits of grading, including borrow and stockpile areas;

(D)          define phases of development of approximately five years of operating capacity each;

(E)           delineate proposed final contours for the C&DLF unit(s) and facility features for closure; and

(F)           delineate physical features including floodplains, wetlands, unstable areas, and cultural resource areas as defined in Rule .0536(c) of this Section.

(2)           Landfill Operation. The following information related to the long-term operation of the C&DLF unit shall be included in facility drawings:

(A)          proposed transitional contours for each phase of development including operational grades for existing phase(s) and construction grading for the new phase; and

(B)          stormwater segregation features and details for inactive landfill subcells, if included in the design or required.

(3)           Survey. A survey locating all property boundaries for the proposed landfill facility certified by a licensed professional land surveyor if required by G.S. 89C.

(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 yearly disposal rates in tons and a representative daily rate that is consistent with the local government approval in accordance with Rule .0536(c)(11) of this Section;

(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 C&DLF unit(s).

(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 estimates of gross capacity of the C&DLF unit; gross capacity for each phase of development of the C&DLF unit; the estimated operating life of all C&DLF units in years; required quantities of soil for landfill construction, operation, and closure; and available soil resources from on-site. "Gross capacity" is defined as the volume of the landfill calculated from the elevation of the initial waste placement through the top of the final cover, including any periodic cover.

(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 systems, if required in accordance with the effective dates and applicability requirements in S.L. 2007-550 s. 9.(b) and S.L. 2013-413 s. 59.1 as amended by S.L. 2013-410 s. 47.6, or if proposed by the applicant. The performance of and design concepts for the leachate collection system within active areas of the C&DLF unit(s) and any storm water segregation included in the engineering design shall be described. Normal operating conditions shall be defined. A contingency plan shall be prepared for storm surges or other considerations exceeding design parameters for the storage or treatment facilities.

(5)           Base liner systems, if required in accordance with the effective dates and applicability requirements in S.L. 2007-550 s. 9.(b) and S.L. 2013-413 s. 59.1 as amended by S.L. 2013-410 s. 47.6, or if proposed by the applicant, shall be described.

(6)           Special engineering features. A description of any special engineering features specific to the landfill that the applicant is proposing shall be provided.

(7)           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 requirements in S.L. 2007-550 s. 8.(b).

(8)           Study of Environmental Impacts. A study of environmental impacts shall be conducted as required by G.S. 130A-295.6(a) in accordance with the effective dates and applicability requirements in S.L. 2007-550 s. 9.(b) and S.L. 2013-413 s. 59.1 as amended by S.L. 2013-410 s. 47.6.
