Southern California Gas Company SL32-21 Sector 2 - Pasadena, California Gas Pipeline Facility

Southern California Gas Company SL32-21 Sector 2 is a natural gas pipeline facility located at 311 W Mountain St, Pasadena, California. It is part of the extensive Southern California Gas Company network, which supplies natural gas to millions of customers across Southern California. The facility is classified under NAICS codes 221210 (Natural Gas Distribution) and 486210 (Pipeline Transportation of Natural Gas), indicating its role in both distribution and transmission. The facility operates under the regulatory framework of the US Pipeline and Hazardous Materials Safety Administration (PHMSA) and the Department of Transportation (DOT) 49 CFR Part 192, which governs gas pipeline safety. As a sector 2 facility, it likely involves high-pressure transmission lines that require robust cathodic protection and regular integrity management. The pipeline infrastructure in California is subject to state-specific regulations from the California Public Utilities Commission (CPUC), which oversees safety and reliability. This pipeline segment plays a critical role in the regional energy grid, delivering natural gas to residential, commercial, and industrial users in the Pasadena area. Its proximity to urban populations necessitates stringent safety protocols and leak detection systems. The facility contributes to the energy security of Southern California, supporting heating, power generation, and industrial processes.

The facility is located in an urban area of Pasadena, near residential and commercial zones. Natural gas pipelines in such settings require careful monitoring to prevent leaks, which can contribute to greenhouse gas emissions and pose explosion risks. The local environment includes the San Gabriel Mountains watershed, and pipeline integrity is important to avoid soil and water contamination. Cathodic protection systems are used to prevent corrosion, a key environmental concern for aging infrastructure.
