Section 2530 - Classification and Siting Criteria(a) Waste management 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 waste management unit to protect water quality. A waste management facility may consist of several waste management units each with a different classification. [Note: for Units that receive only solid waste, see § 20200 -§ 20260, Subdivision 1, Division 2, Title 27 of this Code]. Classification of waste management units for hazardous waste shall be based on the criteria contained in this article, on field inspections by RWOCB and State Water Resources Control Board staffs, and on other pertinent information. Information used to classify waste management units shall be submitted according to the provisions of Article 9 of this chapter. Classified waste management units shall comply with appropriate waste discharge requirements.(b) Existing waste management units for, or that contain, hazardous waste 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 Section 2531 of this article, and summarized in Table 3.1 of this article; and(2) are operating in compliance with Subsection 2510(d) of this chapter.(c) All new Class I landfills, waste piles, and surface impoundments shall be sited, designed, constructed, and operated to ensure that wastes will be a minimum of 5 feet 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 5 feet 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 5 feet above the highest anticipated elevation of underlying ground water and dischargers shall not be entitled to exemption under Subsection 2510(b) of this chapter.(d) All containment structures at waste management units 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 as certified by a registered civil engineer or certified engineering geologist.Cal.
