Section 7103-141.0 - Sludge Distribution and Marketing141.1 Quality Criteria: 141.1.1 Sludge and sludge products for Distribution and Marketing must meet one of the PFRP pathogen reduction standards specified in subsection 87.0, vector attraction methods described in subsection 88.2 as alternative a through h, and the Pollutant Concentration Limits in Table 402.3 at the time of distribution.141.1.2 All sludge or sludge products shall be dried or otherwise amended to a minimum of twenty percent solids prior to distribution or marketing. 141.2 Monitoring Requirements for Distribution and Marketing:141.2.1 A quality control program approved by the Department shall be instituted to assure that all treated sludge and sludge products to be distributed meet the Department's standards regarding the destruction of primary pathogen organisms (PFRP) and the limitations for heavy metals and other contaminants. During the stabilization process, temperature shall be monitored regularly until temperatures recorded in the material (or off-gas from a heat-drying process) exceed the level and duration required for adequate pathogen destruction. For aerobic stabilization processes, oxygen levels shall also be monitored frequently to assure that aerobic conditions are maintained. Additional monitoring of the treatment process may be required on a case-by-case basis.141.2.2 The sludge or sludge products shall be tested according to the frequencies specified in Subsection 401, unless the Department requires a different monitoring as a permit condition.141.2.3 The sludge distribution facility shall perform and submit to the Department additional analyses if there has been a significant change in the quality of the sludge or sludge products. 141.3 Records and recordkeeping.141.3.1 Any person that distributes and markets sludge or sludge products shall keep a log of all persons that receive more than ten (10) cubic yards of material per year.141.3.2 Before distributing sludge or sludge products to any person who will utilize more than 100 tons of the material in a twelve (12) month period, the permittee shall submit a plan to the Department which addresses the following: 141.3.2.1 The end use(s) of the material141.3.2.2 Maximum application rates141.3.2.3 Total amount of material to be utilized141.3.2.4 Storage practices141.3.2.5 Transportation methods141.4 Application limitations. 141.4.1 No person who receives or applies sludge or sludge products pursuant to a distribution and marketing program may exceed the application rates for particular uses as listed in the instructional materials provided with the product, or otherwise use the pr141.4.2 No sludge or sludge products may be stored or applied so as to cause surface or groundwater pollution, runon/runoff, cause odor, adversely affect the food chain, attract vectors, or adversely affect private or public water supplies.7 Del.
