Delta Plating Inc. Inspection Report Page 2of4 Assessment Checklist dated May 19, 2004. The verification was performed through a walkthrough inspection; review of permits, reports and discussion with Mr. Jackson of the San Joaquin CUPA and Mr. Doug Baker Safety & Environmental Manager of Delta Plating on May 20, 2004. Facility Information: The Subject facility, located in the City of Stockton, is composed of several rooms and occupies land area of approximately 0.56 acre, the nearest residential is a cross street west side of the facility. The primary activities are repairing the damaged bumper followed by chrome plating. Mr. Baker explained to us than some portion of the wastewater is being recycled at the facility and reused in the plating operation. However, facilit did not file a recyclingexemption with the —r CUPA. All wastes generated in the plating room, are pumped irectly to the tesaw water treatment units behind the plating room where the waste is treated and discharge into the sewer. Record review indicated that facility was inspected as a generator by the local agency (CUPA). On November 18, 1993, the facility was cited for violation of illegal disposal of plating bath solution onto the ground by the CUPA. A sample was collected and the result indicated elevated nickel and copper levels. On June 22, 1995, facility filed for onsite hazardous waste treatment notification form to operate as a conditionally exempt small quantity treatment (CESQT) with DISC for its wastewater treatment unit. On March 5, 1999, CUPA informed the facility to upgrade its permit from CESQT to PBR due to increased volume of the wastewater treatment operation and treatment of cyanide. On July 31, 2003, Ms. Asha Aroura of DTSC Berkley office received a request from the facility to treat cyanide. Currently, CUPA has enforcement case against the facility and facility has stopped cyanide treatment. During the May 20, 2004, site visit DTS.0 staff identified two areas of concern; the main plating room and the wastewater treatment areas. I observed a several cracks on the floor with standing liquids from plating bath in the bermed area and second area of concern was in the wastewater treatment area which I observed stain and cracks on the floor. However, the phase I Checklist submitted by the facility on May 19, 2004 identified three Areas of Concern (AOCs); 1. Main Plating room 2. Wastewater treatment 3. Storm drain The storm drain area has been cleaned,checked and covered under the oversight of the CUPA according to Mr. Douglas.
