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

Status Impact Report Contents

Section 21695 provides the necessary guidance for a California licensed civil engineer or licensed engineering geologist to prepare an SIR for submittal to CalRecycle, that provides an analysis of the potential impacts to the landfill resulting from the implementation of the organic disposal reduction requirements of PRC Section 42652.5.

The SIR shall describe the potential impacts to the landfill and expected timing of the impacts, including the following analysis:

  • Site development
  • Waste types/volumes
  • Daily and intermediate cover and beneficial use

For intermediate cover:

  1. A description and/or map of the area(s) that have or will have intermediate cover
  2. The length of time that the intermediate cover has been used and expected time that it will be used for each defined area
  3. A description of how the intermediate cover will be maintained to continue to meet the control criteria of Title 27 CCR Section 20700(a)
  4. Information on all instantaneous surface readings for methane of 500 ppmv or greater in the area(s) of intermediate cover that has or will be in place for more than 12 months (as reflected in the most recent annual report filed pursuant to Title 17 CCR Section 95470(b)(3) and consistent with the monitoring requirements of Title 17 CCR Section 95469(a)(1)(A))
  • Volumetric capacity based on the disposal site experiencing a reduction of organic waste disposal of 50 percent by 2020 and 75 percent by 2025
  • Waste handling methods
  • Gas control and monitoring systems
  • Gas generation
  • Operation and closure design
  • Final grading plan
  • Site life estimate
  • Ancillary facilities
  • Cost estimates for closure and post-closure
  • Financial assurance mechanisms for closure, post-closure, and non-water corrective action requirements
