Our sustainable methods include pomace collection for over 50 years, which keeps waste out of our watersheds and river, and certified organic compost production for 30 years which reduces our community’s carbon footprint and helps our soil remain healthy. It is important to us to be considerate neighbors as we have invested several million dollars in operational systems to improve compliance, protect our local streams and river, reduce odors and air pollution. With SB1383 and changing CA Air Resources Board regulations for composting facilities will require more technological investment which will further reduce emissions.

Upper Valley Disposal Services has diverted nearly 30,000 tons and Clover Flat has diverted over 75,000 tons of waste, just in the last two years, into recyclable, reuse products. The total avoided emissions by our operations removes over 30,000 MTCO2e each year. This is the equivalent of removing 46,000 passenger vehicles from the roadway and avoiding 12,000 household energy consumed. We are addressing climate change by providing programs and services that create avoided greenhouse gas emissions (GHG).

Clover Flat Resource Recovery Park is a renewable energy provider. Rather than flaring the methane from this small Class 3 landfill, we invested $4M to collect and capture methane gas which is converted to electricity. Through a partnership with Pacific Gas & Electric Company, we are able to provide the city of Calistoga enough energy to power the equivalent of 800 residential homes continually.
Naturally occurring iron minerals in the soil that have been exposed to air and storm water have been a source of acidification. In 2019, the adjacent seasonal creek to the landfill was impacted, however, there was no evidence the Napa River was impacted. The maintenance practices have been corrected and erosion control measures have been significantly improved.

In early 2020, at Clover Flat, we installed a new Landfill Cover: Posi-Shield. Though its intended use is for soil cover and erosion control, we discovered that it does not burn and helped to stop spread of the Glass Fire. In addition, we have performed the following:

• Established a 24-hour fire watch during fire season by creating a staging area for Illumination Technologies of California, LLC to use its IQ 24-Hour Fire Watch detection system.
• Developed a robust Fire Management Plan which has resulted in no onsite fires since the summer of 2018.
• Substantially increased the dedicated onsite fire water storage capacity and hydrant system at Clover Flat.
• For our customers and Napa Valley residents, we are here to provide environmentally sound disposal of fire debris.

The Company welcomes all inquiries and will be happy to provide a tour to anyone who is interested, as we have done many times for many interested people from neighbors to elected official to regulators to school children. We will continue to assist Napa County and its residents with providing programs and services to combat climate change.
