The Napa, Calif., City Council has approved a $10.4 million upgrade to the Levitin Way recycling center that will help the facility adhere to state environmental laws.
The upgrade will involve placing concrete slabs and a top layer of mature compost on top of the compost piles, replacing the open-air compost system that had been in place since the 1990s. The drainpipe system will also be restructured to direct all stormwater into a single collection pond to be treated.
Napa Valley Register has more information:
Kevin Miller, Napa’s recycling manager, estimated the improvements will raise the plant’s composting capacity under its existing state permit from 40,000 to 66,640 tons per year. A fresh environmental study after work is completed may allow the city to process even more organic waste, as much as 105,000 tons annually, he told the council.
Richmond-based C. Overaa & Co. submitted the winning bid among three candidates, and is scheduled to complete the work around February 2019, Miller announced.
The composting overhaul is being approved amid Napa’s effort to step up the diversion of organic wastes, including food scraps and by-products, as a way to raise the diversion rate away from landfills from 65 to 75 percent by 2020.
