(a)
						Location
(1) Perimeter subsurface monitoring
						wells shall be installed around the waste disposal footprint but not within
						refuse. In some cases the installation of monitoring wells may not be necessary
						around the entire perimeter of the disposal site permitted facility boundary.
						In such a case, the operator shall demonstrate to the satisfaction of the EA
						that landfill gas migration could not occur due to geologic barriers and that
						no inhabitable structure or other property or land use, such as agricultural
						lands, within 1,000 feet of the disposal site permitted facility boundary is
						threatened by landfill gas migration.
(2) Perimeter monitoring wells shall be
						located at or near the disposal site permitted facility boundary. The operator
						may establish an alternate boundary closer to the waste disposal footprint
						based on a knowledge of the site factors in §
													20923(a)(2). When
						compliance levels are exceeded at the alternate boundary, the operator shall
						install additional monitoring wells closer to the permitted facility boundary,
						pursuant to §
													20937.

						may include, but are not limited to: periodic monitoring, utilizing either
						permanently installed monitoring probes or gas surveys, and continuous
						monitoring systems.
(c) Structures

						continuous basis.
(d) When
						practical, structures shall be monitored after they have been closed overnight
						or for the weekend to allow for an accurate assessment of gas accumulation.
						Areas of the structure where gas may accumulate shall be monitored and may
						include, but are not limited to, areas in, under, beneath and around basements;
						crawl spaces; floor seams or cracks; and subsurface utility
						connections.

						Review & Notification--For landfills, the RWQCB shall review the emergency
						response plan, in coordination with the Enforcement Agency (EA), to assure that
						no proposed response to a foreseeable emergency will result in a threat, or
						increased threat, to beneficial uses of waters of the state.
(b) Submittal--For landfills for which the
						CIWMB requires an emergency response plan (
e.g., pursuant to §
													21130
), the discharger
						shall submit a copy of that plan, including any proposed amendments thereto, to
						the RWQCB. For landfills having an existing emergency response plan that has
						already been reviewed by the RWQCB, the discharger need not resubmit the plan
						for review by the RWQCB until such time as the plan is amended. For landfills
						having an existing emergency response plan (i.e., approved by the EA) that has
						not as yet been reviewed by the RWQCB, the discharger shall submit a current
						copy of the plan for RWQCB review prior to July 18, 1998. For proposed
						emergency response plans (including proposed amendments to an existing plan),
						this submittal shall occur at the same time as the discharger submits the
						proposed plan to the EA.
(c)
						Coordinate On New Response--In the event that the discharger proposes to
						respond to an emergency in a manner other than specified in the emergency
						response plan, the RWQCB shall coordinate with the EA to assure that the
						proposed response does not pose a threat to water quality.

(a)
						Remove Free Liquids--All free liquid remaining in a surface impoundment at the
						time of closure shall be removed and discharged at an approved waste management
						unit (Unit). All residual liquid shall be treated to eliminate free
						liquid.
(b) Options--Following
						removal and treatment of liquid waste, impoundments shall be closed in one of
						two ways, as approved by the RWQCB.
(1)
						Mandatory Clean-Closure Attempt--Unless the discharger demonstrates, and the
						RWQCB finds, that it is infeasible to attempt clean-closure of the impoundment,
						then all residual wastes, including sludges, precipitates, settled solids, and
						liner materials contaminated by wastes, shall be completely removed from the
						impoundment and discharged to an approved Unit. Remaining containment features
						shall be inspected for contamination and, if not contaminated, can be
						dismantled. Any natural geologic materials beneath or adjacent to the closed
						impoundment that have been contaminated shall be removed for disposal at an
						appropriate Unit. For surface impoundments that are successfully clean-closed,
						as herein described, the RWQCB shall declare the Unit no longer subject to the
						SWRCB-promulgated requirements of this title. If, after reasonable attempts to
						remove such contaminated materials, the discharger demonstrates that removal of
						all remaining contamination is infeasible, the surface impoundment shall be
						closed as a landfill or land treatment unit, as appropriate, pursuant to
						¶(b)(2).
(2) Fallback Closure
						Options--In cases where clean-closure [under ¶(b)(1)] is infeasible, the
						discharger shall propose for RWQCB approval either:
(A) Closure As a Landfill--that all residual
						wastes, including sludges, precipitates, settled solids, and liner materials,
						shall be compacted, and the Unit shall be closed as a landfill pursuant to
						§
														21090, provided that the closed
						Unit meets applicable standards for landfill Units in Articles 3 and 4 of
						Subchapter 2, Chapter 3, Subdivision
						1 of this division (§
														20240 et seq.), and further
						provided that the moisture content of residual wastes, including sludges, does
						not exceed the moisture-holding capacity of the waste either before or after
						closure; or
(B) Closure As an
						LTU--for surface impoundments which contain only decomposable wastes at
						closure, that the Unit be closed as a land treatment unit under §
														21420(a) (2 -
						4).

(C15: Section 2583)

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						Options--Waste piles shall be closed in one of two ways, as approved by the
						RWQCB.
(1) Mandatory Clean-Closure
						Attempt--Unless the discharger demonstrates, and the RWQCB finds, that it is
						infeasible to attempt clean-closure of the waste pile, then all waste materials
						and any components of the containment system which are contaminated by wastes
						shall be removed from the waste pile and discharged to an appropriate Unit.
						Remaining containment features shall be inspected for contamination and, if not
						contaminated, can be dismantled. Any soil or other materials beneath the closed
						waste pile that have been contaminated shall be removed for disposal at an
						appropriate Unit. If, after reasonable attempts to achieve clean-closure (as
						herein described), the discharger demonstrates that removal of all remaining
						contamination is infeasible, then the remaining portions of the waste pile
						(including all contaminated portions of the underlying and surrounding geologic
						materials) shall be closed as a landfill pursuant to ¶(a)(2) and §
													21090.
(2) Fallback Options--In cases where
						clean-closure [under ¶(a)(1)] is infeasible, the discharger shall propose
						for RWQCB approval either of the following options, as appropriate.
(A) Closure As a Landfill--A waste pile can
						be compacted, covered, and closed as a landfill §
														21090, provided that the
						discharger has met the requirements of ¶(a)(1), and further provided that
						the closed Unit either meets applicable standards for landfill Units in
						Articles 3 and 4 of Subchapter 2, Chapter 3, Subdivision
						1 of this division (§
														20240 et seq.), or contains only
						dry waste and was not required to have a leachate collection and removal system
						under §
														20340(a).
(B) Closure As an LTU--Waste piles which
						contain only decomposable wastes may be closed as a land treatment unit under
						§
														21420(a) (2 -
						4).
