Landfill Methane Capture Strategy
Established by the Climate Action Team March 2006
The Strategy includes the following components: Install new methane control systems at landfills
currently without systems;Maximize landfill methane capture efficiencies
through optimizing landfill design, operation, and closure/postclosure practices; and
Increase recovery of landfill gas that is currently flared as a biomass renewable energy source to avoid emissions from fossil fuel energy sources.

Improving Emissions Measurement MethodsCalifornia Energy Commission’s PIER Program Study:
Improved Methods for Landfill Methane Emissions in California
Goal: Develop an improved GHG inventory methodology for landfill methane emissions in California, based on a field-validated emissions model inclusive of seasonal methane oxidation.
3-year Project (2007 – 2010); Project Participants: Jean
Bogner, Kurt Spokas, Jeff Chanton
Includes 3 tasks: Template for collecting site-specific data; Theoretical/empirical modeling development; and Field validation of methodology.

EPA Method OTM 10 for Non-Point Source Measurement
Challenges/Questions Regarding the MethodWhat is the best optical configuration for large
sources?What area is measured (plume capture)?What factors affect plume capture?How do we separate top and side slope
emissions?How do we estimate emissions per unit area?
