Notice of Exemption

Exempt Status
Type, Section or Code
Common Sense, Section 15061(b)(3)
Reasons for Exemption
DTSC has determined with certainty that there is no possibility that the activities in question may have a significant effect on the existing environment because the project would not result in "a substantial, or potentially substantial, adverse change in any of the physical conditions within the area affected by the project, including land, air, water, minerals, flora, fauna, ambient noise, and objects of historic or aesthetic significance.” The project is consistent with applicable state and local environmental permitting requirements including, but not limited to, air quality rules such as those governing volatile organic compounds and water quality standards, and approved by the regulatory body with jurisdiction over the site (City of Ontario). The majority of remediation activities (e.g., SVE installation) would occur indoors and would not have the potential to negatively impact adjacent or nearby receptors, which include residential and industrial land uses. The limited number of trucks (16 total trips) and limited timeframe for activities (approximately 26 weeks) would also not have the potential to substantially impact existing truck traffic in the project area.
