October 17, 2017 ‘Odor Workshop’ at West Placer Waste Management Authority (WPWMA)
At the 7th Annual ‘Odor Workshop’ at the WPWMA facility on Fiddyment Road, agency staff gave an overview and PowerPoint presentation of the facility in general and measures taken over the recent 7-year since the stepped-up measures to control ‘odors’. We will post the PowerPoint presentation on our website for photos for full info, but briefly, some concerns addressed were:
- The Landfill began operations in 1979 (long before housing in the area); site life estimate is through 2058. Materials Recovery Facility began in 1995 per AB939.
- In general, two primary odor sources are ‘composting’ on the north side and ‘landfill gas’ on the south side. Complaints are mostly seasonal—air settles in the cooler weather and tends to generate more complaints. They encourage residents to use their online reporting system to report odors—the system can actually track where those odors could be generating from (real-time demonstration shown)—there are many other potential odor sources in the area, not just the landfill plant.
- The pilot study using ‘misting’ had minimal results, just wasn’t working well to mask odors. However, they have made changes to the composting system and that pilot study has shown to be effective and speeds up processing for less odor emissions. They will go full scale in the new facility to be located across the street.
- Methane gas caused by organic materials in the green-waste, is being recaptured now to provide to Bay Area for sales, and looking toward future feed to PG&E lines. However, its release must be carefully controlled (per government regulations)—if too much is taken out too quickly, it’s dangerous and could cause an explosion or flare fires that burn underground.
- About 40% of their materials are fully recyclable, and they continue to work towards full product recycling. Mr. Oddo said many local areas sell waste to China, to be reused and shipped back as product—he wants to keep it here for reuse into new products.
- They will continue to partner with local educational sources—William Jessup, and future campuses (Sacramento State campus in the Placer Ranch Plan and Warwick in west Placer County) and create research facilities on site here for this partnership.
- They offered a ‘tour’ for the local Neighborhood Associations, Loren Cook will coordinate with board members.
