The South Coast Air Quality Management District (SCAQMD) has initiated a new rulemaking process to address underground natural gas storage, generally an unregulated source.  The rule is being created in response to the Aliso Canyon Leak, when an estimated 94,500 tons of natural gas were released into the atmosphere in October 2015.  SCAQMD held a working group meeting on January 26th, 2017 to discuss Proposed Rule 1148.3 – Natural Gas Underground Storage Facilities.

The Proposed Rule 1148.3 is based on the California Air Resources Board's Oil and Gas Regulation and will apply to aboveground operations at natural gas underground storage facilities.  The purpose of the rule is to reduce total organic carbon (TOC) and toxic emissions from natural gas underground storage facilities and will include an ambient monitoring plan, daily screening, and leak detection and repair (LDAR) requirements.  The rule is currently scheduled to be considered for adoption in summer 2017.
