Section 20240 - SWRCB-Classification and Siting Criteria. (C15: Section 2530)(a) Units and Facilities--Waste management units (Units) shall be classified according to their ability to contain wastes. Containment shall be determined by geology, hydrology, topography, climatology, and other factors relating to the ability of the Unit to protect water quality. A waste management facility can consist of several Units each with a different classification. Classification of Units shall be based on the criteria contained in this article, on field inspections by RWQCB and SWRCB staffs, and on other pertinent information. Information used to classify Units shall be submitted according to the provisions of Article 4, Subchapter 3, Chapter 4 of this subdivision (§ 21710 et seq.). Owners or operators of classified Units shall comply with waste discharge requirements (WDRs) adopted by the RWQCB.(b) Reclassification--Existing Units shall be reclassified according to applicable criteria in this article, provided that such Units: (1) comply with siting criteria for each category of existing Units in § 20250 and § 20260, and summarized in Table 3.1 of this article; and(2) are operating in compliance with § 20080(d).(c) Five-Foot Separation--All new landfills, waste piles, and surface impoundments shall be sited, designed, constructed, and operated to ensure that wastes will be a minimum of five feet (5 ft.) above the highest anticipated elevation of underlying ground water. Existing landfills, waste piles, and surface impoundments shall be operated to ensure that wastes will be a minimum of five feet (5 ft.) above the highest anticipated elevation of underlying ground water. For new and existing land treatment units, the base of the treatment zone shall be a minimum of five feet (5 ft.) above the highest anticipated elevation of underlying ground water and dischargers shall not be entitled to exemption under § 20080(b).(d) Unit Foundation--All engineered structures (including, but not limited to, containment structures) constituting any portion of a Unit shall have a foundation or base capable of providing support for the structures, and capable of withstanding hydraulic pressure gradients to prevent failure due to settlement, compression, or uplift and all effects of ground motions resulting from at least the maximum probable earthquake [for Class III Units (see § 20370)] or the maximum credible earthquake [for Class II Units (see § 20370)], as certified by a registered civil engineer or certified engineering geologist.
