LMH Environmental, Inc. July 6, 2019 Ms. Elianna Florido, REHS Via Email San Joaquin County Environmental Health Dept. 1868 East Hazelton Ave. Stockton CA 95205 Re: Pat Fruth Inc.Diesel Fuel and Motor Fluids Spill; Lodi CA Cal OES Control No. 19-3393 San Joaquin County Record No. COQDPHYHI LMH Project No. CA-19-07 GWCC Claim No. P69145 Dear Ms. Florido: On May 27, 2019, a truck operated by Pat Fruth Inc. of Clearwater, Minnesota, caught fire shortly after being parked at the Love's Travel Stop at 15250 Thornton Road northwest of Lodi. As a result of efforts to extinguish the fire, a small volume of Diesel Fuel, Motor Oil, and Antifreeze from the truck's refrigeration unit was spilled onto the parking lot beneath the truck and trailer. The approximate site location is indicated on Figure 1, which includes an excerpt of the Terminous CA USGS 7 'h minute quadrangle sheet (1993 Revision). Since this map as well as more recent revisions do not show the actual location of the Love's Travel Stop, an aerial photo downloaded from Google Earth is included on Figure 2 to show that location. LMH Environmental Inc. of Orangevale CA was authorized to direct the environmental cleanup of the spill site by Great West Casualty Company, the insurer for Pat Fruth Inc. LMH hired Patriot Environmental Services (Sacramento office)to complete the cleanup. The Woodbridge CA Fire Dept. responded to the site to extinguish the fire and noted that an estimated 15 gallons of Diesel Fuel, 5 gallons of Motor Oil, and 3 gallons of Antifreeze were spilled onto the asphalt surface of the parking area. Most of these liquids were flushed into a Curb Inlet for the facility storm drain system located within 50 feet of the location at which the truck was parked. A Site Utility Master Plan was provided to LMH by Love's, and an excerpt of this Plan is included on Figure 3. The approximate locations of the parked Pat Fruth truck and the Storm Drain Drop Inlet are indicated on Figures 2 and 3. Patriot inspected the storm drain system and found that none of the spilled products had flowed beyond a second Storm Drain Curb Inlet located 255 feet southwest of the Curb Inlet near the truck. Patriot opened the lid of a Storm Drain Interceptor located about 50 feet further southwest of the second Curb Inlet and verified that none of the spilled petroleum products had entered the Interceptor. The approximate locations of the second Stone Drain Curb Inlet and the Storm Drain Interceptor are indicated on Figures 2 and 3. Patriot used a pressure washer to flush residual petroleum products from the parking area to the facility storm drain system where they could be collected and removed. Patriot used a trailer- mounted "mini-guzzler" at both Curb Inlets to remove the flushing water and residual petroleum liquids from the storm drain system. A total of three drums of"oily water" were collected for disposal. Patriot also collected all of the physical debris and absorbents resulting from the truck WESTERN REGION •P.O.Box 1164 • Orangevale, CA 95662 • (916)971-2727 EASTERN REGION •PO Box 824• Union,KY 41091 • (859)384-0031
