Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Section 15330
Reasons for Exemption
1. The project is consistent with Class 30 as a minor cleanup action taken to prevent, minimize, stabilize, mitigate, or eliminate the release or threat of release of a hazardous waste or substance and will cost $1 million or less. 2. None of the exceptions in title 14, section 15300.2 apply to the project. The site is not on the Hazardous Waste and Substances Sites List pursuant to Government Code section 65962.5. The site is not in a known area of biological or cultural resources. 3. The project will not result in significant impact to the environment because of the following controls that are included in the approved workplan and are required to be implemented. (a) Dust suppression measures (covering and/or watering the soil stockpiles) will be conducted during demolition and excavation activities. Storage pile covers with sand bag hold-downs will be used on the external clean fill stockpile to prevent storm water runoff and general migration of the stockpile. (b) All project activities will be conducted pursuant to the means and methods described in the IM Workplan and consistent with the HASP. The IM Workplan contains the HASP, which incorporates DTSC, Cal OSHA and Federal worker health and safety regulations. The workers will be trained for hazardous waste handling and properly equipped for the impacted soil to be handled. (c) Work activities will be conducted on weekdays 7 am to 5 pm. Transport departure times will be scheduled so as to avoid peak commuter traffic. (d) All trucks will be decontaminated prior to leaving the facility. Based on the facility location and the selected transportation, no specific traffic control measures would be necessary. The trucks will exit the facility going east on West Sherman Avenue, turn right (south) on South Broadway, turn right (west) on West Albertoni Street, turn right (north) on South Vermont Avenue, and turn right (east) on West Artesia Boulevard. The trucks will enter the 110 Freeway southbound and travel to the 405 Freeway, merge onto the 405 Freeway northbound to the 5 Freeway, and merge onto the 5 Freeway and continue to the final disposal destination facility. (e) Appropriate permits will be obtained from the City of Carson, the LADPW and any other applicable agency. (f) Air permits will not be required. Rule 1166 will not apply based on the limited VOC levels. Best Available Control Measures from Table 1 of Rule 403 will be implemented for particulates. Emission estimates from diesel tractor/trailers were calculated for transportation. Based upon 50 trucks/day, the NOx emission rate would be 2.08 lbs/day, which is well below the emission threshold of 125 lbs/day level requiring mitigation measures in the SCAQMD CEQA Air Quality Handbook for air impact during the transportation.
