Integrated Recycling, Inc. <br /> March 12, 1996 <br /> Steven Mindt <br /> San Joaquin County Public Health Services <br /> 304 E. Weber Avenue, Third Floor <br /> P.O. Box 388 <br /> Stockton, CA 95201-0388 <br /> Re: Alternative Composting Method Proposal <br /> This purpose of this letter is to confirm the receipt of your letter of January 11, 1996 regarding the <br /> establishment of an acceptable Process to Further Reduce Pathogens (Process to Further Reduce <br /> Pathogens) for an alternative composting method. A demonstration project, as you suggested, is an <br /> excellent means of testing the effectiveness of our composting method. There are several changes we <br /> would like to suggest with respect to your testing protocol: <br /> 1. We would like to use fecal Coliform as the pathogen indicator organism. We did an extensive <br /> search to find a laboratory that performs Salmonella sp. tests and found that that test as set <br /> forth in Section 17868.3(b)(1) is not performed. The one lab that does perform Salmonella tests <br /> does not do a multiple tube fermentation (MPN) and only provides its results in term of positive <br /> (+) or negative (-). They said they could look into a multiple tube fermentation method, but the <br /> test would cost at least$225, compared to $25 for fecal Coliform. On the basis of cost and the <br /> fact that the regulations state that either test can be used, we propose to proceed with fecal <br /> Coliform testing. <br /> 2. We would like the demonstration project to proceed until May 1. <br /> 3. We would like to submit the results of the demonstration project to your department on June 1. <br /> The following areas we will perform as directed in your letter: <br /> 1. We will test for pathogens on a monthly basis <br /> 2. We will track the material in the compost piles such that accurate temperature readings for <br /> discrete portions of compost can be made. <br /> I apologize for the tardiness of this letter. If you have any questions please contact me at (916) 325- <br /> 2577. <br /> Sincerely, <br /> Blake Tresan <br /> cc: Thomas Sanchez, Vice-President, Operations, CRS <br /> 2114 N Street <br /> Sacramento,CA 95816 <br /> 916-325-2577 <br /> 916-325-9762 FAX <br /> Recycled Paper <br />
