Senate Bill 1383

California’s short-lived climate pollutant (SLCP) reduction strategy targets landfills as the third largest sources of methane in the state with organic waste comprising half of landfill contents.

Emissions from organics account for 20% of the state’s methane emissions—more than 3x more potent than carbon dioxide—presenting a major threat to human health and the environment.

To minimize the impact of organic waste on the climate crisis, the State of California aims to reduce storage of organic waste by the solid waste industry through compliance with requirements of Senate Bill 1383 (SB1383).

GLA’s California licensed civil engineers and licensed engineering geologists can assist the private solid waste industry and municipal solid waste facility operators with navigating these new guidelines to facilitate timely regulatory compliance. Services include:

  • Preparing Status Impact Reports (SIR) for California Department of Resources and Recycling (CalRecycle) in compliance with Title 27 of the California Code of Regulations Sections 21695 and 20750.1 amendments (requiring analysis of potential impacts to the landfill design and operation that may result from a reduction in the amount of organic waste disposed)
  • Assessing, designing, installing, maintaining and operating environmental monitoring systems (groundwater monitoring wells, landfill gas monitoring probes, landfill gas extraction wells)
  • Designing organics material processing and handling facilities
  • Calculating incoming tonnage and volumetric capacity and assessing impacts to the operational density of material currently being landfilled
  • Ancillary facilities
  • Performing data collection and analysis, filling data gaps
  • Analyzing impacts to development of the landfill due to the reduction in incoming organics, including operations, operating equipment, waste handling methods, ancillary facilities, future interim cell development due to reduction in size and/or increased in life, daily and intermediate cover and beneficial reuse material, and closure design
  • Developing grading plans, including performing slope stability analysis
  • Estimating facility site life
  • Review closure/post-closure designs and cost estimates, and non-water release corrective plan action cost estimates
