Aspen Tackles Three Major Projects for the CPUC: Natural Gas Compressor Station Modernization and Two Complex Power Line Replacements
Aspen Environmental Group is proud to be managing three Environmental Impact Reports (EIRs) simultaneously for the California Public Utilities Commission (CPUC) — a reflection of our team's depth, agility, and expertise in energy infrastructure and CEQA compliance.
The three projects are the Ventura Compressor Station Modernization Project, the Moraga-Oakland X 115 kV Rebuild Project, and the Ivanpah-Control Project. They represent significant infrastructure proposals by Southern California Gas Company (SoCalGas), Pacific Gas and Electric Company (PG&E), and Southern California Edison (SCE), respectively. Each brings its own environmental, technical, and community-specific challenges, and Aspen is leading the charge to ensure thorough, transparent, and defensible environmental reviews.
SoCalGas Ventura Compressor Modernization Project
Located in Ventura County, SoCalGas's proposed project involves replacing or upgrading an aging natural gas compressor station. Aspen’s team is evaluating the potential environmental effects associated with air quality, noise, public health and safety, and nearby sensitive receptors — all in a region already deeply concerned about cumulative impacts from energy infrastructure. We’re coordinating with CPUC staff, local agencies, and stakeholders to provide clear, objective analysis and facilitate robust public engagement.
PG&E Moraga-Oakland X 115 kV Rebuild Project
Further north, Aspen is also managing the EIR for PG&E’s proposed replacement of four circuits of 115 kilovolt transmission lines in Alameda and Contra Costa counties, including the cities of Orinda, Piedmont, and Oakland. The Moraga-Oakland X project crosses a complex urban-wildland interface, involving multiple jurisdictions, creek crossings, wildfire-prone areas, and highly engaged communities. Our interdisciplinary team is navigating wildfire risk, sensitive biological resources, traffic, safety issues, and the feasibility of underground construction in narrow, steep, and winding roadways — all while ensuring that the CEQA process remains both efficient and inclusive.
Extending over more than 260 miles through Inyo, Kern, and San Bernardino Counties, SCE’s Ivanpah-Control Project would replace or upgrade power line infrastructure to serve communities from the Bishop to Barstow. The project passes through areas with some of the state’s most valuable Native American history and resources, as well as historic mining districts and recreation areas with spectacular views of Mount Whitney and the Alabama Hills.
