The Sonoma County Waste Management Agency previously prepared a Draft Environmental Impact Report examining the impacts of a Proposed Ordinance on the subject of carryout bags.". The intent of the Proposed Ordinance is to reduce the environmental impacts related to the use of single-use carryout bags. It is anticipated that by prohibiting single-use plastic carryout bags and requiring a mandatory charge for each paper bag distributed by retailers, the Proposed Ordinance would provide a disincentive to customers to request paper bags when shopping at regulated stores and promote a shift to the use of reusable bags by retail customers, while reducing the number of single-use plastic and paper bags within the Study Area. The Final Environmental Impact Report addresses comments made during the Draft Environmental Impact Report comment periods.

The Sonoma County Waste Management Agency (SCWMA) has prepared a Recirculated Draft Environmental Impact Report (RDEIR) for the SCWMA Compost Facility. This RDEIR addresses an increase in the amount of material processed at the Central Site Alternative from 110,000 tons per year (analyzed in the “2011 Draft EIR) to 200,000 tons per year (analyzed in this Recirculated Draft EIR). To assure that all the resource areas are appropriately analyzed, all the resource areas for the Central Site Alternative are reviewed in this RDEIR for impacts related to the increased capacity and operational changes. As to the increased throughput, recirculation of the entire 2011 Draft EIR is not required because other sites (Sites 5A and 40) were already analyzed for 200,000 tons per year.
