Oil & Natural Gas Production, Processing, and Storage
This page last reviewed February 6, 2017
The California Global Warming Solutions Act of 2006 (AB 32) establishes a comprehensive program of regulatory and market mechanisms to achieve real, cost-effective, quantifiable reductions of greenhouse gases (GHG). AB 32 charges the Air Resources Board (ARB) as the agency responsible for monitoring and regulating many GHG emission sources to reduce state GHG emissions to 1990 levels by 2020. This is the main webpage for the Oil & Natural Gas Production, Processing, and Storage measure, intended to reduce GHG emissions from crude oil and natural gas operations. For questions related to the program, please contact Joseph Fischer at (916) 445-0071.
Oil & Gas Methane Regulation Development:
"Source Testing of Fugitive and Vented Emissions From Hydraulic Fracturing Operations and Wastewater Ponds Used in Crude Oil and Natural Gas Operations in California," SAGE Environmental Consulting, June 2016
Because of a limited sample size, this report did not estimate greenhouse gas, criteria pollutant, or toxic air contaminant emissions from well stimulation treatments. However, an uncontrolled step in the well stimulation process was discovered: uncovered circulation tanks. This source is being addressed in the proposed Oil & Gas Methane Regulation.
This study also examined a set of oil field produced water ponds. These ponds may or may not have held produced water from a well that had been stimulated. Regardless, no well stimulation chemicals were detected, but methane, carbon dioxide, non-methane hydrocarbon, and toxic air contaminant emissions were measured. Again, due to a small sample size, ARB is proposing a new research study to get additional data from ponds, before deciding whether or not to proceed with possible control measures.
