SoCalGas Distribution Mains & Services Methane Emissions Map
SoCalGas is providing customers with a consolidated, searchable map that demonstrates Distribution Mains and Services methane emissions data collected since 2016. The data is collected through the company's various routine surveying practices and operational and maintenance practices of its distribution pipeline system. The data is updated on an annual basis (June- July) to include the datasets of future years.
SoCalGas Efforts to Reduce Distribution Mains & Services Methane Emissions
We have a long-standing commitment to modernizing our system infrastructure to increase safety and reliability and reduce methane emissions. We continually use the best management practices and technology to minimize & detect emissions. Some of the most effective steps we have taken include:
Prioritizing Leak Repair
We have developed and implemented a Decision Tree method to prioritize leak repairs.
In order to reduce leaks in the system, we created a Project Management Team with dedicated crews to gain efficiency through leak mitigation best practices.
Accelerating Leak Surveys
Leak surveys on distribution lines have historically been performed according to State and Federal Regulations to ensure safety. We continuously evaluate and increase leak surveys across the Distribution Pipelines to make the system more resilient and robust.
Aerial Methane Mapping Technology
The use of this innovative technology has resulted in a substantial increase in the speed and frequency in which leaks can be identified and repaired. This allows us to better assess and enhance our mitigation efforts.
Working with state and federal agencies
For close to 30 years we have been protectively working to reduce GHG and methane emissions through the EPA's Natural Gas Star Program. Since 2017, we have been a partner in EPA’s Methane Challenge, another voluntary GHG reporting and reduction program. SB 32 (Pavley, 2006) requires a 60% reduction of GHG emissions below 1990 levels by 2030.
In addition to our voluntary program efforts, we also have our Leak Abatement Program to reduce methane emissions in compliance with SB 1371, which mandates gas utilities to reduce methane emissions by 20% of their 2015 baseline by 2025.
How to Navigate the map
From the bar above the map:
- Use the Year field to select a year.
- Enter a ZIP Code or choose one from the drop-down list.
- For an alternative view of the emissions, select the layer box at the top right corner of the map, and select "Methane Emissions Hatch."
Pipelines may be located anywhere, including under streets and sidewalks, and on private property. This map shows the general locations of SoCalGas pipeline projects. Make sure to contact 811 at least two days before you dig for any of your home projects.
