CONSOLIDATED REGULATIONS FOR TREATMENT, STORAGE, PROCESSING OR DISPOSAL OF SOLID WASTE CHAPTER 3. CRITERIA FOR ALL WASTE MANAGEMENT UNITS, FACILITIES, AND DISPOSAL SITES SUBCHAPTER 4. CRITERIA FOR LANDFILLS AND DISPOSAL SITES ARTICLE 2. ALTERNATIVE DAILY COVER MATERIAL AND BENEFICIAL REUSE This database is current through 06/23/06, Register 2006, No. 25. s 20690. CIWMB -Alternative Daily Cover. [T14: s17682, s17258.21(b)] (a) General Requirements (1) Alternative materials of alternative thickness for daily cover (other than at least six inches of earthen material) for municipal solid waste landfill units may be approved by the EA with concurrence by the CIWMB, if the owner or operator demonstrates that the alternative material and thickness control vectors, fires, odors, blowing litter, and scavenging without presenting a threat to human health and the environment. (2) Alternative daily cover alone, or in combination with compacted earthen material, shall be placed over the entire working face at the end of each operating day or at more frequent intervals to control vectors, fires, odors, blowing litter, and scavenging without presenting a threat to human health and the environment. For the purposes of this section, the operating day shall be defined as the hours of operation specified in the solid waste facility permit, and may extend for more than 24 hours if operations are continuous. Waste-derived alternative daily cover shall be processed prior to spreading and compacting on the working face and applied and compacted to ensure that all exposed waste is completely covered by ADC and that there are no open voids within the cover material or in contact within the underlying wastes. Waste materials used as ADC that already meet the grain-size specifications of these regulations, or an alternative grain size approved by the EA and CIWMB pursuant to this section, need not be processed if the EA determines that the material as received at the landfill is adequate to perform the functions of daily cover and meets the appropriate specifications. (3) Should the application of alternative daily cover become impracticable or contribute to conditions hazardous to public health and safety and the environment, the owner or operator shall terminate such use and revert to the use of compacted earthen cover material in accordance with s20680. For the purposes of this section, impracticable conditions are those which make placement of alternative daily cover difficult due to adverse climatic or other conditions such that the performance requirements of%a)(2) cannot be met. (4) The owner or operator shall place compacted earthen material over the entire'working face at the end of any operating day preceding a period of time greater than 24 hours when the facility is closed, unless procedures as required by the EA are in place to ensure that the requirements of%a)(2) and (a)(3) are met. A stockpile of earthen cover material and required equipment shall be available to ensure a corrective response to violation of 1(a)(2) and (a)(3). Whenever an EA determines that an application of ADC is not meeting the requirements of this standard, the EA may direct the operator to immediately cover the ADC with soil. The continuing use of ADC that has been determined by the EA as not meeting the requirements of this section may become the basis for the EA to take enforcement action to seek compliance with the requirements of this section. http://weblinks.westlaw.com/Find/Default.wl?DB=CA%2DADC%2DTOC%3BADCCATO... 7/7/2006
