Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						Class II waste management units (Class II "Units") shall be designed and
						constructed to prevent migration of wastes from the Units to adjacent geologic
						materials, ground water, or surface water, during disposal operations, closure,
						and the post-closure maintenance period. Class II and Class III MSW landfills
						are also subject to any applicable waste containment system design requirements
						of SWRCB Resolution No. 93-62 to the extent that such requirements are more
						stringent than those applicable to a non-MSW Class II or Class III landfill
						under this subdivision.
(b) Each
						Class II Unit shall be designed and constructed for the containment of the
						specific wastes which will be discharged.
(c) Class III landfills shall have
						containment structures which are capable of preventing degradation of waters of
						the state as a result of waste discharges to the landfills if site
						characteristics are inadequate.
(d)
						For the purposes of this paragraph, the words "new" and "existing" have the
						same meaning as described in §
												20080(d). New
						landfills, waste piles, and surface impoundments shall comply with the
						requirements of this article. Existing waste piles and surface impoundments
						shall be fitted with liners and leachate collection and removal systems as
						described in §
												20330 and §
												20340 as feasible. Existing
						landfills and waste piles shall have interim cover as described in §
												20705. Existing landfills, waste
						piles, and surface impoundments shall be fitted with subsurface barriers as
						described in §
												20360 as needed and feasible, and
						shall have precipitation and drainage control facilities as described in §
												20365. Existing surface
						impoundments shall comply with §
												20375. New and existing land
						treatment units shall comply with §
												20377. All existing Units shall
						comply with the seismic design criteria in Section
						20370.
(e) Containment structures shall be designed
						by, and construction shall be supervised and certified by, a registered civil
						engineer or a certified engineering geologist. Units shall receive a final
						inspection and approval of the construction by RWQCB or SWRCB staff before use
						of the Unit commences.
(f) The
						discharger shall maintain the integrity of containment structures in spite of
						normal excavation or fire control work; nevertheless, for fire control work,
						the discharger can damage containment structures to the extent necessary to
						control the fire, so long as the discharger promptly repairs such damage after
						extinguishing the fire. Excavations made as part of discharge operations shall
						not result in removal of any portion of a containment structure.
(g) Stability Analysis--For any portions of
						the Unit's containment system installed after July 18, 1997 for which the RWQCB
						has not approved a slope and foundation stability report on or before that
						date, the discharger shall meet the requirements of §
												21750(f)(5).
