Document Description
The Department of Toxic Substances Control (DTSC) approved the 410 E32nd Street & 317 E. 33rd Street Removal Action Workplan (RAW). The removal action includes remediation of Volatile Organic Compounds (VOCs) in vadose zone soil vapor with Soil Vapor Extraction (SVE) technology followed by long term monitoring and recordation of a Land Use Covenant (LUC). The SVE program is intended to reduce the subsurface mass to the extent possible and thereby reducing the vapor intrusion threat.

Exempt Status
Type, Section or Code
CCR, Sec. 15061(b)(3)
Reasons for Exemption
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. Although the site is on the Hazardous Waste and Substances Sites List (Cortese List), the activities are designed to remediate the site. 2. The site is in a previously developed area and does not provide habitat value. 3. In addition, the activities will have no potential for a significant impact due to project controls that will be implemented during the project as summarized below. • A California-state licensed construction contractor will conduct any additional drilling activities associated with possible future expansion of the SVE system which has been installed for the Pilot Test. 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 was 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, personal protective equipment, and controls of open trenches for worker safety as described below. • 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 is currently operating 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. • 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, Jacobs, 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. • Sound attenuation is provided by the walls of the building itself and by sound-attenuating blankets installed around the air handling equipment. Effluent piping outlets have been routed to a location which is 92 feet away from the nearest residence. • 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. • Vapor discharge from the treatment system will comply with emission standards specified in South Coast Air Quality Management District Rule 1166. • The community surrounding the Site will not be affected because the noise and dust levels will be controlled by engineering controls. 4. DTSC submitted a Sacred Lands file search to the Native American Heritage Commission (NAHC) and received no requests for consultation regarding the project.
