Document Description
Apex Envirotech, Inc. is proposing bioremediation at the site of a gasoline and diesel fuel spill within the California Department of Transportation’s (Caltrans) right-of-way along State Route 70 in Plumas County at post mile 35.479. The site is the location of an overturned tanker truck that spilled approximately 1,960 gallons of gasoline and approximately 2,700 gallons of diesel fuel on September 14, 2018. In the days following the spill, there was an extensive cleanup effort to remove contaminated soil. The work proposed by Apex Envirotech, Inc. would include the application of Micro-Blaze Emergency Liquid Spill Control (Micro-Blaze) diluted in water to soils in both road shoulders using a water truck with a pressurized hose. Following the application of Micro-Blaze, a six-week remediation period would follow with weekly inspections of the moisture and runoff systems, followed by confirmation soil sampling at the 90-day point, in accordance with a bioremediation workplan. The work would require temporary lane/shoulder closures. Caltrans will issue an encroachment permit (0222-6MC-0233) for the proposed work within the right-of-way.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Hazardous Waste Cleanup, Section 15330
Reasons for Exemption
It is Caltrans’ understanding that the Central Valley Regional Water Quality Control Board is the CEQA lead agency for the project. Caltrans has review authority for the issuance of encroachment permits (e.g., a discretionary permit) that address work occurring within Caltrans’ right-of-way. The work proposed within Caltrans’ right-of-way is categorically exempt in accordance with Section 15330 (Minor Alterations to Prevent, Minimize, Stabilize, Mitigate or Eliminate the Release or Threat of Release of Hazardous Waste or Hazardous Substances) Class 30. Class 30 consists of any minor cleanup actions taken to prevent, minimize, stabilize, mitigate, or eliminate the release or threat of release of a hazardous waste or substance which are small or medium removal actions costing $1 million or less. Examples of such minor cleanup actions include but are not limited to: (4) Onsite treatment of contaminated soils or sludges provided treatment system meets Title 22 requirements and local air district requirements. The work proposed within Caltrans’ right-of-way would have no significant effect on the environment.
