PLEASE ADDRESS REPLY TO: T ' ENVIRONMENTAL SERVICES U LLEY POST OFFICE BOX 1211 G WEBS rn MODESTO, CALIFORNIA 95353 PHONE: (209) 572-5516 FAX: (209) 572-5298 July 15, 1994 Mr. John Stark California Department of Fish and Game, Region If P.O. Box 2148 Lodi, CA 95241 Dear Mr. Stark: This is to follow-up with you and provide you with information relating to what we have done to remedy the situation arising out of the release of processing water from Tri Valley Growers Plant 4 in Stockton into Bear Creek which occurred last week. (Our process water consists principally of organic fruit matter from our food processing plant.) We have reported this release to the Regional Water Quality Control Board (RWQCB) and, as a courtesy, to the State Office of Emergency Services. The RWQCB has directed us to continue to work with Fish and Game to resolve this matter. We consulted with Lori Oldfather of Fish and Game last Friday, July 8, 1994, who agreed that a flush of approximately one million gallons of fresh water from the Woodbridge Irrigation District would be a good first step to restoring the system. Woodbridge discharged 1.5 million gallons of water to the creek on Friday afternoon and evening. Tri Valley Growers made an inspection of the creek Saturday morning, July 9, 1994. A sizable portion of the organic matter in the creek had been cleared up by the flush of fresh water, but there were still areas that appeared to contain visible organic matter. To protect the fish resources, Tri Valley Growers added an alpha biocatalyst on Satu day to that portion of the creek which still exhibited symptoms of excess organic ma ter. Enclosed is the Material Safety Data Sheet for the biocatalyst along with other in rmation which will be useful in your evaluation of the product. The biocatalyst is desig ed to provide an oxygen rich environment favorable to naturally occurring bacteria hat use organic matter from our process water as a food source and to prevent the form tion of anaerobic bacteria. A follow-up inspection by Tri Valley Growers on Mond y, July 11 showed the creek to be clear, clean, and consistent with its past appearanc . I have enclosed copies of the lab reports containing the analyses which you requested. The results indicate that the principle outcome of the process water mixing with the creek was a reduction in the oxygen content of the water. Next week I should be receiving the results of an additional set of samples that were taken subsequent to our clean-up efforts in order to ensure that the waters were restored to their earlier P.O.
