Current through Register Vol. 46, No. 28, July 10, 2024
(a)
					 Applicability. Except as described by the transition requirements of section
					 360.4  of this Title, all new landfills, lateral and vertical expansions of
					 existing landfills, and subsequent development at existing landfills must conform
					 to the requirements set forth in this Subpart.
(b) The owner or operator must submit
					 engineering reports, design drawings, and specifications for all new construction
					 of landfill components described in this Subpart prior to construction.
					 Construction must not commence before written approval is received from the
					 department.
(c) The landfill liner
					 and leachate collection and removal system must be designed and constructed to
					 effectively protect surface and groundwater resources from uncontrolled releases
					 of landfill leachate. The components of the liner system must be placed to
					 achieve a minimum slope of no less than two percent, except along leachate
					 collection pipes, which must have a minimum slope of one percent.
(d) Any geomembrane, geosynthetic clay liner
					 (GCL), geosynthetic drainage layer, geocushion or other geosynthetic material
					 installed on landfill side slopes must be designed to minimize shear stresses and
					 to withstand the calculated tensile forces acting upon the geosynthetic materials
					 by the transfer of anticipated destabilizing forces to the landfill subgrade. At
					 a minimum, the design must consider the maximum friction angle of any
					 soil-geosynthetic or geosynthetic-geosynthetic interface, along with seepage
					 forces expected in the side slope soil drainage layer in the primary leachate
					 collection and removal system, to ensure that overall slope stability is
					 maintained and to meet the factor-of-safety requirements specified in paragraph
					 363-4.3(c)(3) of this Part.
(e) For
					 lateral expansions adjacent to existing landfills that do not meet the liner
					 system requirements of this Part (i.e., the existing liner system is single
					 composite and the expansion requires double composite), any encroachment on the
					 existing landfill's side slope must be designed and constructed to meet the liner
					 system requirements of this Part.
(f)
					 Landfills must be designed to minimize the need to decommission existing
					 monitoring wells and to install new monitoring wells as a result of progressive
					 cell construction into areas where monitoring wells are located.
(g) A pre-construction meeting must be held
					 prior to commencement of construction. This meeting must include, at a minimum:
(1) distribution to each involved entity of
					 relevant CQA and CQC documents and supporting information;
(2) review the role of specific CQA and CQC
					 requirements in demonstrating conformance with design criteria;
(3) review of responsibilities, authorities and
					 lines of communication for each involved entity;
(4) review of established acceptance and
					 rejection criteria as specified in CQA and CQC plan;
(5) review of methods for documenting and
					 reporting all data;
(6) review of
					 procedures for storage and protection of landfill construction materials on-site;
					 and
(7) a site walk-around to
					 identify project site layout and material and equipment storage
					 locations;
