There seems to be some confusion as to what tests need to be <br /> conducted on the composted green waste. <br /> Below are listed the specific test requirements as mandated by the green waste <br /> regulations: <br /> 1. Daily temperature readings of compost per 100 feet of windrow or 250 cubic <br /> yards of active compost (CCR 17877). Weekly temperature readings of non- <br /> active compost per 100 feet of windrow or 250 cubic yards (CCR 17876 (5). <br /> 2. Leachate testing of organo-phosphates using EPA method 8140 using one <br /> sample of leachate from five separate composting batches, plus nitrate testing <br /> (CCR 17876 (A) 1). These testing results should also be sent to the Regional <br /> Water Quality Control Board. <br /> 3. Environmental Health Standards - metal concentrations testing as outlined in <br /> CCR 17887. Representative composite sample for every 5,000 cubic yards of <br /> green compost produced shall be tested. <br /> 4. Pathogen Reduction Standard - Pick a method to be utilized as outlined in CCR <br /> 17887 (2). <br /> 5. All analysis for constituents and pathogens shall be performed by a Department <br /> of Health Services certified laboratory. Quality Assurance/Quality Control <br /> (QA/QC) documents shall be included. A certification that indicates the <br /> pathogen reduction criteria are met. The certification shall be completed using <br /> CIWMB Form 5000. <br /> A Division of San Joaquin County Health Care Services <br />
