CPUC to Consider Revising Pipeline Biogas Standards

California has some of the strictest pipeline biogas requirements in the country, which can add significantly to the costs of pipeline biogas projects.  As a result, the state enacted legislation in 2016 requiring the California Council on Science and Technology (CCST) to review the standards for the heating value (BTU) and siloxanes.  The CCST report recommends that the CPUC consider reducing the BTU requirement to as low as 970.  CCST recommends further study on the siloxanes standard and suggests that monitoring requirements be reduced for biogas sources that are unlikely to have siloxanes (diverted organic waste, dairy, forest and agricultural waste).
