Common Sense Exemption [CCR, Sec. 15061(b)(3)]

Based on the following reasons, DTSC has determined with certainty that there is no possibility that the activities in question may have a significant effect on the 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." 1. The Project Site is located in a previously developed area surrounded by an urbanized mix of land uses. 2. The Project Site does not provide habitat value. 3. The Project activities will have no potential for a significant impact due to project controls that will be implemented during the project as summarized below. 4. A California-state licensed construction contractor will conduct any additional drilling activities associated with possible future installation of the SVE system. Fieldwork will be conducted following the safety guidelines provided in a site-specific health and safety plan (SSHSP) prepared specifically for the project. The SSHSP will be prepared in accordance with guidelines set forth in Title 8 of the California Code of Regulations, Section 5192 and includes but is not limited to project controls for heavy equipment safety operations, air monitoring for on and off-site emissions. 5. Well drilling activities will be conducted by California-licensed contractors in accordance with permits acquired from the Los Angeles County Department of Public Health, Environmental Health Division, Drinking Water Program. The Pilot Test system will operate under a Site-Specific Permit To Operate (PTO) from South Coast Air Quality Management District. If required, construction permits will be obtained from the City of Los Angeles Building Department. 6. Site security will be established according to the type of operations, potential for exposure to contaminants, and potential for contact with other safety hazards. Site security measures that will protect the construction area and prevent unauthorized access include the following: Access will be controlled by the existing fencing, rolling gate, and structures. Only the construction crew, contractor staff, and authorized personnel will be on the Site during working hours. No unauthorized personnel will be allowed in the controlled areas of the Site. All visitors must have prior approval from the contractor, and DTSC before being admitted to the Site. All visitors must read and acknowledge the SSHSP and possess documentation that they have the training necessary to enter the active work zone. 7. Sound attenuation is provided by the fencing and by sound-attenuating blankets installed around the air handling equipment. Effluent piping outlets would be routed to a location which is greater than 800 feet away from the nearest residence. 8. All fieldwork will be conducted according to a SSHSP and only properly trained personnel will be employed. Licensed contractors and transporters will also be used. Prior to trenching, the Underground Services Alert (USA) will be contacted for locating specific Pipelines/conduits/electrical/phone/water/sewer, etc. 9. Vapor discharge from the treatment system will comply with emission standards specified in South Coast Air Quality Management District Rule 1166. 10. The community surrounding the Site will not be affected because the noise and dust levels will be controlled by engineering controls.
