Aspen supported the Gaskell West Solar Project by providing compliance inspection services for biological, cultural, and paleontological resources.

In September 2010, Aspen was awarded a contract to provide on-call National Environmental Policy Act (NEPA) and other Environmental Services for Western Area Power Administration (WAPA), Sierra Nevada Region (SNR).

Aspen is providing design, CEQA/NEPA, permitting, and mitigation monitoring services to Palmdale Water District (PWD) for sediment removal at Littlerock Reservoir. Located on National Forest System (NFS) lands of the Angeles National Forest (ANF), Littlerock Reservoir is a man-made feature formed by the impoundment of water by the Littlerock Dam.

Under contract with the County of San Luis Obispo, Planning and Building Department (County), Aspen is assisting the County with application review, environmental review, and support with multi-agency coordination for the decommissioning of the Diablo Canyon Power Plant (DCPP), a nuclear energy power plant off the coast of San Luis Obispo County.

Under contract with the County of Los Angeles Department of Regional Planning, Aspen supported the County with the preparation of a biological assessment, noise technical study, and Environmental Impact Report (EIR) for the County’s update to the Santa Monica Mountains North Area Plan (NAP) and Community Standards District (CSD).

Aspen provided technical support to the California Energy Commission’s (CEC) Energy Research and Development Division’s (ERDD) Electrical Program Investment Charge (EPIC) Program.

Under contract to the California Department of Conservation (DOC), Aspen prepared a Program EIR assessing oil and gas well stimulation treatments throughout California, as required by SB 4 as amended, which required the Division of Oil, Gas and Geothermal Resources (DOGGR) to evaluate the impacts of well stimulation treatments that may occur from either existing or future oil and gas wells, including hydraulic fracturing and acid well stimulation.

Aspen prepared an EIR on behalf of San Luis Obispo County for the CVSR proposed by SunPower Corporation. SunPower proposed to con­struct and operate a controversial 250 MW solar photovoltaic power plant on approxi­mately 4,000 acres of rangeland in the Carrizo Plain, an unincorpo­rated portion of eastern San Luis Obispo County.

Units 2 and 3 of the San Onofre Nuclear Generating Station (SONGS) were shut down in January 2012. Unit 2 last operated on January 9, 2012, when it was removed from service for a planned refueling and maintenance outage.

Aspen provided environmental support for various projects under Sacramento Municipal Utility District (SMUD)’s Environmental Regulatory Support Services on-call contract.

The VCPWA-WP contracted Aspen to prepare the required CEQA/NEPA documents and permits for the Ventura River (VR-1) Levee Rehabilitation Project.

Aspen has provided a variety of environmental services to the USACE for the Santa Ana River Mainstem Project. The Santa Ana River Mainstem Project is a major flood control project spanning 75 miles along the Santa Ana River – from the upper canyon in the San Bernardino Mountains downstream to the Pacific Ocean at Newport Beach.

Western Area Power Administration and Aspen developed an EA (which mirrors an MND in many respects) and seven operation and maintenance (O&M) Plans and procedures in response to proposed changes in O&M procedures within Western’s Central Valley Project and Pacific AC Intertie ROWs and the Transmission Agency of Northern California’s (TANC) California-Oregon Transmission Project ROWs.

Because the potential for flooding along the Santa Paula Creek channel is considered life threatening, the USACE began construction of the flood control channel at Santa Paula Creek in June 1997.

Aspen completed this 2,000-page document in 1992 for a Joint Review Panel consisting of Santa Barbara County, the State Lands Commission, the U.S. Army Corps of Engineers, and California EPA.
