SMUD is proposing to remove and dispose of cement foundation debris
which is remaining from EDF Renewables Kennetech wind turbines from the Solano Wind Resource Area. There were approximately 59 Kennetech turbines with 3 to 4 foundations supporting each turbine. The foundations are -1 to 2 feet in diameter and are 8 to10 feet deep. SMUD is proposing to remove the concrete foundations with a backhoe and backfill the holes with native soil or crushed aggregate. The debris will be hauled offsite using a dump truck and all debris will be disposed of at an appropriate landfill. Other facilities such as transformers, associated electrical equipment, concrete pads, and transformer boxes will also be cleaned up
and disposed of in accordance with local and state laws and regulations. The ground surface will be leveled to conform with the surrounding grade. The site will be accessed using existing paved and gravel roads. The project is anticipated to start in July 2019 or soon thereafter and last for approximately 3 months.
The project site is located east and north of Stratton Lane
and west of Talbert Lane in unincorporated Solano County, California. The area surrounding the proposed project is primarily non-native annual grassland used for dryland farming and grazing.
Notice of Exemption
Type, Section or Code
Sec. 21080(b)(9); 15261
Reasons for Exemption
Under CEQA Guidelines § 15062, a lead agency must identify the rationale for making the determination that a project is exempt under CEQA. SMUD has determined that the Collinsville Property Debris Cleanup Project is exempt under CEQA Guidelines §15061 (b)(3) General Rule Exemption which reads "Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA" § 15304, Minor Alterations to Land, which reads, "Class 4 consists of minor alterations in
the condition of land, water, and/or vegetation that do not involve the removal of healthy, mature, scenic trees except for forestry or agricultural purposes including grading on slopes of less than 10%, landscaping, and minor trenching and backfilling where the surface is restored ... " The Collinsville Property Debris Cleanup Project involves the removal of concrete foundations and minor site restoration, and will not result in any change to the existing landscape and therefore is considered exempt in accordance with CEQA Guidelines §15061 and §15304.
