Carpenter Co.-Lathrop Division - Executive Summary |
|
1. Accidental release prevention and emergency response policies It is the policy of Lathrop Division to comply fully with all federal, state, and local rules and regulations regarding the proper handling, use, storage, and emergency response preparedness to prevent accidental release of chemicals toxic or otherwise. Furthermore, Lathrop Division is committed to protecting the health and welfare of both its employees and community residents. Lathrop Division makes all efforts not to have and accidental release by having: a. Training and testing program b. Safety check sheet c. Equipment inspections Our emergency response is based upon the requirements in OSHA's Hazardous Waste and Emergency Operations (HAZWOPER) regulation (29 CFR 1910.120) and the Busniess Plan per state and local regulations. For emergency response, the company has in place: a. Contingency plan b. Evacuation plan c. Chemical spill procedures d. First aid and C PR training 2. Stationary source and regulated substance handled The Lathrop Division operation in Lathrop, California is located at 17100 S Harlan Rd and occupies 486,000 square feet. Carpenter Co. is located east of I-5 and is surrounded by an industrial neighborhood. The facility is located on 35 acres. Carpenter Co. Lathrop Division manufactures polyurethane foam products primarily for use in furniture, cushioning, bedding, undercarpet padding, and packaging. The manufacturing process incorporates the use of TDI, which is reacted with polyol and water to produce flexible foam products. Inside the building, up to 250,000 pounds of TDI are stored in two steel storage tanks. The two tanks are located in a cement pit that functions as a spill containment area. TDI is shipped primarily via railcar, which contains approximately 190,000 pounds. 3. Worst case scenario and alternative release scenario Losing the entire contents of a railcar (190,000 lbs) would be the worse cas e release. If this happens the contents would enter our storm drains through two nearby storm grates and would consequently be collected in our sump. The sump and the storm drains are large enough to hold the contents of two railcars. The sump pumps are turned on only during the rainy season or as needed. The storm water system is not connected to the local city storm water system. The surface area coverd by the spill would be aprroximately 7520 square feet. The results for the SCREEN3 run indicate that the hightest concentration of TDI is found a distance of 19 meters (62 feet) from the spill site, with a maximum one hour concentration of 40.76 ug/m3. The toxic endpoint for TDI as listed in the California regulations is 7000 ug/m3. Based upon these results, the toxic endpoint will not be exceeded either offsite or onsite. 4.
