Natural Gas Leak Abatement


In 2014, California passed Senate Bill (SB) 1371, which requires the CPUC to adopt rules and procedures to minimize natural gas leakage from the natural gas pipelines it regulates.

In January 2015, the CPUC initiated a Rulemaking to implement the bill. The purpose of this effort is for the CPUC to:  

  • Mitigate hazardous leaks consistent with PU Code 961  
  • Reduce GHG emissions in conjunction with the California Air Resources Board (CARB) 


On July 24, 2015 the CPUC issued a Ruling setting the Scope and Schedule of the Leak Abatement proceeding. The Ruling divided the scope of the proceeding into two phases:


Phase 1: Policies and Guidelines  

This phase addresses utility reporting requirements and the aggregation of emissions data. This phase seeks to establish best practices for Leak Abatement. In June 2017, a decision was issued that established best practices and reporting requirements for the CPUC Natural Gas Leak Abatement Program.


Phase 2: Ratemaking and Performance-based Financial Incentives 

This CPUC will commence this phase to address utility incentives to upgrade their natural gas system to mitigate methane emissions.
