Mr. Houghton January 30, 2023 Page 2 of 2 of at the landfill prior to the implementation of the organic disposal reduction requirements; describe the basis of that estimate. Indicate the estimated percentage of organic waste to non-organic waste. Methods may include the following: i. If the landfill has existing records of specific organic and non- organic waste material types, then the analysis could include the breakdown of types. If not, then a totalized volume of all organic waste and all non-organic waste is sufficient. ii. The SIR could utilize existing records for the landfill or can make assumptions from past studies such as CalRecycle's previous Waste Characterization Studies (circa 2014, 2018, 2021). CalRecycle waste characterization studies are available on the website at: Waste Characterization Studies Listing (ca.gov) iii. Data may be available from the transfer facility operators and/or contributing jurisdictions that deposit wastes at your landfill. b. Indicate any actual and/or anticipated reductions in organic waste types/volumes resulting from the implementation of the organic disposal reduction requirements. Include organics reductions experienced prior to January 2020, since January 2020 and anticipated by January 2025. i. The SIR should consider all organic waste reduction experienced at the landfill prior to and since 2020, including the food wastes required to be reduced since January 1, 2022. Data may be available from the transfer facility operators and/or contributing jurisdictions that deposit wastes at your landfill. 2. Section 3 Daily and Intermediate Cover and Beneficial Use, does not provide sufficient information regarding the intermediate cover and methane emissions for intermediate cover. The evaluation shall also include Daily and intermediate cover and beneficial use; (2). The length of time that the intermediate cover has been used and expected time that it will be used for each defined area. • Provide a table or description of the timing of intermediate cover per 3(A)(1) above. (4). Information on all instantaneous surface readings for methane of 500 ppmv or greater in the area(s) of intermediate cover that has or will be in place for more than 12 months. ii. The location of each such exceedance shall be identified consistent with the monitoring requirements of 17 CCR Section 95469(a)(1)(A).
