Notice of Exemption

Exempt Status
Type, Section or Code
General common sense exemption under CEQA Guidelines Section 15061(b)(3)
Reasons for Exemption
This project does not have the potential for causing a significant effect on the environment. The project results in minor increases in criteria pollutants and greenhouse gas emissions that are well below the District’s CEQA mass emission thresholds (approximately 2.10 lb/day NOx, 0.78 lb/day ROC, 10.67 lb/day CO, 1.97 lb/day SOx, 0.197 lb/day PM10, 0.197 lb/day PM2.5, and 2,793 MT CO2e/yr). The project does not trigger District requirements for an Air Quality Impact Analysis or Health Risk Assessment pursuant to District Regulation VIII: New Source Review. The project triggers requirements for Best Available Control Technology (BACT) which is satisfied via the installation of units that are guaranteed by the manufacturer to meet 12 ppm NOx at 3% oxygen and 100 ppm CO at 3% O2 when properly tuned. As a result of the project, the emission offset thresholds of Regulation VIII are exceeded for NOx at the UCSB Stationary Source for the first time. UCSB has satisfied its offset liability through the surrender of the required offsets. The project will comply with all applicable District rules and regulations and is therefore consistent with the 2022 Ozone Plan. The District considered the potential for the project to affect environmental resources aside from air quality, including water use and energy use. The project will not result in additional water or electricity use at Building 657. Natural gas consumption is expected to increase by 11.1%, but this minimal increase has no potential to cause a significant impact on energy resources.
