New State Law Requirements for Self-Haul Organic Waste

The SB 1383, California’s Short-Lived Climate Pollutant Reduction Strategy, require commercial organic waste generators, including landscapers, to maintain certain records if they comply with the organic waste collection service requirement by self-hauling their generated organic waste. (Title 14, Chapter 12, Article 3, Section 18984.9) 

The records commercial businesses that self-haul must keep are:

  • Delivery receipts and weight tickets from each entity receiving organic materials, including the amount of organic material in cubic yards or tons.
  • If the organic waste is transported to a site that does not have scales or that employs scales incapable of weighing the waste received, the self-hauler is not required to record the weight of material. However, the self-hauler must maintain a record of the entity that received the organic waste.

For more information on self-hauling requirements visit CalRecycle.  You can also download this CalRecycle_Recordkeeping_tool_Self-Haulers to help you track your self-hauling.

Residential self-haulers do not need to maintain these records.

History of Clover Flat Resource Recovery Park

Clover Flat Resource Recovery Park LogoClover Flat initially began as a Class III landfill accepting municipal solid waste in upper Napa County and is now also a Resource Recovery Park and renewable energy provider. Rather than flaring the methane from this small Class 3 landfill, we 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.

The County of Napa sited and permitted Clover Flat Landfill in the late 1950s and it opened for business by 1963. The Landfill was purchased by Bob and Marvin Pestoni in 1966 and this leadership team created sustainability practices which have become the standards for industry, state of California and other jurisdictions. Today, Clover Flat employs 26 full time staff who live in and are raising their families in Napa County.

As California assumed a leadership role in the global effort on climate change, the state has begun enacting laws requiring more recycling and diversion of materials. The Clover Flat leadership team has enabled the Recovery Park to recycle 50% of what it disposes. In addition, Clover Flat has been and is currently operating at NET ZERO emissions meaning our Recovery Park is not producing more carbon emissions than what its saving. We are doing our part in the global effort on climate change and will continue our commitment to our community.

With the passing of SB 1383, a short-lived climate pollutant reduction mandate, more organics diversion programs are being planned and executed. These programs include:

  • Next Phase of Clean Energy Production – We are planning to develop operations to create more renewable energy for our community. Clover Flat will continue to expand on its clean energy production with the addition of a wood bio-gasification plant. This plant will create an additional one mega- watt of power for the local community while solving the community’s challenge of creating ongoing defensible space. This facility will also assist the local farming community with an alternative to open burning. The slow high heat baking of wood biomass will create the bi-product of bio-char and can be used for a number of applications, notably sequestering carbon.
  • Cal Green Building Code – in our effort on building sustainable partnerships, we are working with contractors to comply with California’s Green Building Code. We have established a Construction & Demolition process prior to any construction materials being disposed in the landfill. Concrete, wood, plastics, metals and fibers are removed and recycled. Currently the facility is compliant with the 65% diversion mandate of the Cal Green Building Code requirement.
  • Organics Processing – Green, wood and commercial food scraps will be diverted and composted. A new composting facility has been permitted and is under construction. This facility will add to our current composting operations that will keep our soils healthy, help conserve water, and sequester more carbon emissions. Currently, Clover Flat is assisting homes and businesses in the fire-stricken zones process brush and tree clearing.
  • Recycling and Collection of House Hold Materials – We will continue to offer the Upper Valley community a location for drop off recycling, universal waste, e-waste and purchase of CRV materials. The Glass Fire burned the recycling drop off area of facility but we are planning to re-open the CRV buy-back center. Please check back with us shortly.
