The Alliance Drews Energy Facility (ADEF) was reviewed under Public Resources Code section 25705, which granted the California Energy Commission (Energy Commission) emergency permitting authority, and Executive Order D-26-01, issued February 8, 2001 and Executive Order D-28-01 issued on March 7, 2001. In Executive Order D-26-01 and D-28-01, the Governor ordered the Energy Commission and other relevant state and local agencies to expedite review of proposed thermal power plants for construction and operation on an emergency basis by September 30, 2001. The Governor also declared that these projects were emergency projects under Public Resources Code section 21080(b)(4), and are thereby exempt from the requirements of the California Environmental Quality Act (CEQA).

On April 25, 2001, the Energy Commission approved the 40 megawatt (MW), simple-cycle, natural gas-fired ADEF. The facility is owned by Colton Power, LP and is operated by PurEnergy Operating Services, LLC. Commercial operation began on August 15, 2001.

The ADEF is located on the Drews substation site at 559 South Pepper Avenue in the City of Colton, San Bernardino County. The site, approximately two acres in size, is located approximately one half mile south of Interstate 10 and a Southern Pacific Railroad line, approximately one mile east of South Riverside Avenue, approximately one mile west of South Rancho Avenue, and approximately one mile north of West Agua Mansa Road, within the Agua Mansa Industrial Corridor Specific Plan area. There are no structures on parcels immediately adjacent to the site to the north, west, or south, as the facility is surrounded by protected Delhi Sand flower-loving fly habitat and potential habitat for the Los Angeles pocket mouse. The California Portland Cement Company borders the site to the east.

ADEF is a distributed generation facility that consists of four General Electric 10 MW simple-cycle, gas turbine generators installed in a simple cycle configuration for use in meeting peak power demands by the California Department of Water Resources and the city of Riverside. Project components include gas compression, selective catalytic reduction emission control systems, and evaporative inlet air cooling.

The Energy Commission Decision included a provision that would allow for the certification to be extended for the life of the project, provided that the conditions of certification were current and in compliance, the project was permanent in nature, and air emission credits were in place. On April 11, 2012, the Energy Commission approved the extension of the ADEF for the life of the facility, until such time that it ceases operations and commences permanent closure activities.

Small Power Plant Exemption Evaluation Process

The SPPE process allows projects between 50 and 100 MW to proceed with local approval rather than requiring an Energy Commission license. This exemption from the Energy Commission licensing process can be applied to projects that would not create a substantial adverse impact on the environment or energy resources. The Energy Commission acts as the lead agency under the California Environmental Quality Act (CEQA) and will prepare an Initial Study and Mitigated Negative Declaration that examines public health and safety, along with environmental impacts of the proposed project, including all related facilities such as electric transmission lines, natural gas and water pipelines. If the exemption is granted, the applicant would still need to secure the appropriate licenses and permits from relevant local, state, and federal agencies.
