Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
Design Plan and
						Installation.
(1)
Design
						Plan
: If a gas collection and control system which meets the
						requirements of either sections
						95464(b)(1),
						95464(b)(2) or
						95464(b)(3) has
						not been installed, the owner or operator of a MSW landfill must submit a
						Design Plan to the Executive Officer within one year after the effective date
						of this subarticle, or within one year of detecting any leak on the landfill
						surface exceeding a methane concentration of 200 ppmv pursuant to section
						95463(b)(2)(B).
						The Executive Officer must review and either approve or disapprove the Design
						Plan within 120 days. The Executive Officer may request that additional
						information be submitted as part of the review of the Design Plan. At a
						minimum, the Design Plan must meet the following requirements:
(A) The Design Plan must be prepared and
						certified by a professional engineer.
(B) The Design Plan must provide for the
						control of the collected gas through the use of a gas collection and control
						system meeting the requirements of either sections
						95464(b)(1),
						95464 (b(2) or
						95464(b)(3).
(C) The Design Plan
						must include any proposed alternatives to the requirements, test methods,
						procedures, compliance measures, monitoring, and recordkeeping or reporting
						requirements pursuant to section
						95468.
(D) A description of potential mitigation
						measures to be used to prevent the release of methane or other pollutants into
						the atmosphere during the installation or preparation of wells, piping, or
						other equipment; during repairs or the temporary shutdown of gas collection
						system components; or, when solid waste is to be excavated and moved.
(E) For active MSW landfills, the design plan
						must identify areas of the landfill that are closed or inactive.
(F) Design the gas collection and control
						system to handle the expected gas generation flow rate from the entire area of
						the MSW landfill and to collect gas at an extraction rate to comply with the
						surface methane emission limits in section
						95465 and component leak standard
						in section
						95464(b)(1)(B).
						The expected gas generation flow rate from the MSW landfill must be calculated
						pursuant to section
						95471(e).
1. Any areas of the landfill that contain
						only asbestos-containing waste, inert waste, or non-decomposable solid waste
						may be excluded from collection provided that the owner or operator submits
						documentation to the Executive Officer containing the nature, date of
						deposition, location and amount of asbestos or non-decomposable solid waste
						deposited in the area. This documentation may be included as part of the Design
						Plan.
