Former International Light Metals, formerly Martin Marietta, Hazardous Waste Facility Post-Closure Permit Renewal

Former International Light Metals, formerly Martin Marietta, Hazardous Waste Facility Post-Closure Permit Renewal

The California Department of Toxic Substances Control (DTSC), pursuant to authority granted under Division 4.5, California Code of Regulations, Title 22, Chapter 20 prepared an addendum to renew the existing Hazardous Waste Facility Post-Closure Permit (Permit) to continue the Post-Closure care activities at the Former International Light Metals, formerly Martin Marietta Hazardous Waste Facility (Facility), for ten additional years. DTSC received a Post-Closure Permit Renewal Application for the Facility as authorized by the California Health and Safety Code, Chapter 6.5. The Facility is located at 19200 South Western Avenue, Los Angeles, CA 90501 and is subject to Post-Closure care as required closure performance standards could not be met during closure activities. The Post-Closure Plan (PCP) requires the owner/operator to continue requirements of the Corrective Action Consent Agreement (CACA) executed for the Facility in December 1998 and any subsequent revisions and other requirements imposed by DTSC. The PCP requires the continued annual groundwater monitoring of the groundwater monitoring wells, inspect, repair, maintain and report on the integrity and general condition of the wells, and inspection, repair and maintenance of the concrete and asphalt paving covering the former Hazardous Waste Management Unit 6. DTSC entered into a CACA with the Permittee on December 21,1998 and issued a new Permit on 3/07/2013. Former International Light Metals Facility, formerly Martin Marietta, was previously an industrial metal processing plant supporting the military aviation industry. Operations began in the early 1940’s after the start of World War II and continued until 1992. Site operations included the extruding and forging of aluminum and titanium, as well as other metal fabrication processes. The facilities were demolished in 1995 and site soils were remediated. This project would not affect any aspect of the environment and requires no new construction. All additional activities will continue to be consistent with the Permit and will not result in physical changes. There are no proposed physical changes to the Facility and the continuation of the Permit is consistent with the conclusions of the previously adopted Negative Declaration for which the prepared addendum is updating.
