HAWAII COUNTY MECHANICAL - BIOLOGICAL TREATMENT FACILITY CONCEPTUAL DESIGN <br />Product Quality Requirements <br />The State of Hawaii Department of Agriculture does not regulate the sale of fertilizers and soil <br />amendments. This means that products do not need to be registered with the State before sale, <br />and related fees are not assessed or collected. It also means that at this time there are no quality <br />standards put in place by the State for this type of product. It is required, however, to submit a <br />sample of the compost (soil amendment) to an independent laboratory and then submit a copy <br />of the report to the State Plant Quarantine Branch. This is a requirement for soil amendments <br />that are imported. <br />The Hawaii Department of Health's Solid and Hazardous Waste Branch regulates only the <br />production of specific compost products; there are currently no regulations for selling or <br />marketing compost in Hawai i. However, compost produced from sewage sludge must comply <br />with the federal EPA 503 regulations. These regulations require that the pathogen and heavy <br />metal limits outlined in Exhibits 4 and 5 be met. <br />In many States, the 503 regulations are used as a default for the regulation of MMSW compost. <br />In most cases the MMSW composts meet these regulatory standards. In some jurisdictions, the <br />503 limits are adopted in combination with a content limit for inert materials and a stability <br />standard. Inert materials are defined as man -made materials such as glass or plastic, while <br />stability measures the level of biological activity in the compost. For MSW compost products, <br />individual State numerical standards can be more difficult to meet. <br />EXHIBIT 4 <br />US EPA Sewage Sludge (Biosolids) 503 Regulations, Trace Element Limits <br />Pollutant Pollutant Concentration Limits for <br />Exceptional Quality Biosolids (mg /kg) <br />Arsenic <br />41 <br />Cadmium <br />39 <br />Copper <br />1,500 <br />Lead <br />300 <br />Mercury <br />17 <br />Molybdenum <br />-- <br />Nickel <br />420 <br />Selenium <br />36 <br />Zinc <br />2,800 <br />EXHIBIT 5 <br />US EPA Sewage Sludge (Biosolids) Regulations, Pathogen Limits <br />Pathogens Limit <br />Salmonella < 3 MPN /4 grams of total solids <br />Fecal Coliform <1000 MPN /gram of total solids <br />
