Section 7103-119.0 - Project Development Reports: Specific Requirements for Land Application SitesSludge or sludge products which meet the minimum quality criteria of Subsection 117.0 and Section 600, but do not meet Exceptional Quality criteria for marketing and distribution, may only be applied to sites permitted for land application. Land application to permitted sites may be for agricultural, silvicultural, reclamation or research purposes. The following information is required in the Project Development Report for each land application site:

This element should be prepared and submitted to the Department early in the process so that unsuitable sitesreas can be eliminated from further analysis.119.2 Soils description.119.2.1 Each Project Development Report shall contain a description of:119.2.1.1 Soils within the proposed permit area, including a description of the depth, matrix, color, texture, structure, pH, consistency, degree of mottling and, if present mottled colors and coarse fragment content for each horizon of soil from the surface to a depth of at least five (5) feet or bedrock, whichever is shallower.119.2.1.2 Any subsurface conditions adversely affecting lateral or vertical drainage of the land.119.2.1.3 A delineation of soil areas at the site which are not suitable for land application of sludge.119.2.1.4 The applicant shall base the description on a sufficient number of pits, hand augerings, or excavations to allow an accurate characterization of the soils within the proposed permit area. As a minimum, however, the Department requires that at least one sample be taken for every 5 to 10 acres of each soil series to confirm NRCS.119.2.2 All classifications and interpretations of soil materials required by this section shall be based on criteria specified in the United States Department of Agriculture Handbooks 436 (Soil Taxonomy) and 18 (Soil Survey Manual).119.2.3 The Project Development Report shall include a chemical analyses for each major soil series per field at the proposed site. Soil chemistry testing must be in accordance with the Methods of Soil Analysis published by the American Society of Agronomy, or otherwise shall be consistent with Department guidance. Results are to be expressed on a dry soil basis. The constituents to be tested are pH, cation exchange capacity, percent organic matter, plant nutrient status, total cadmium, total copper, total lead, total nickel, total zinc.119.2.4 For sites where sludge was previously applied within 5 years to the proposed permit area, the application shall also describe background concentrations for all constituents identified above for similar soils where sludge has not been applied.119.2.5 The information required by this section shall be prepared by qualified persons in soil science or land treatment.119.3 Ground water information. The Project Development Report shall contain a description of the ground water hydrology of the proposed site and adjacent area. The following information shall be prepared by a Geologist or a Professional Engineer qualified in hydrology and licensed to practice in the State of Delaware.119.3.1 A map of the site and surrounding area showing all potential contamination sources (such as large on-site systems, feedlots, bulk storage facilities, etc.). Surface water bodies within 1,000 feet of the site boundary of the proposed sludge application area shall also be located.119.3.2 Description of the geology of the area, including the lithology and thickness of the outcropping and subcropping or underlying formations. Any unique or important geomorphological features which could influence ground water flow directions should also be indicated.119.3.3 The following hydrogeological information should be provided to the Department: 119.3.3.1 The thickness, saturated thickness, and depth to water (DTW) of the water table aquifer. The depth to water measurement should indicate the level of the local seasonal high water table.119.3.3.2 The DTW of the seasonal high water table formed by a perched water table when these water table types exist.119.3.3.3 The thickness, lithology, and name of the geological formation which forms the first aquitard of aquiclude beneath the water table aquifer.119.3.3.4 The name of the first confined aquifer beneath the ground surface including the name(s) of the formation(s) composing this aquifer.119.3.4 A description of the ground water flow patterns under the proposed site. A hydraulic head contour map with ground water flow lines should be included in the description. When the direction of the ground water flow cannot be determined with any degree of confidence, observation wells (piezometers) in numbers sufficient enough to determine ground water flow direction may be required.119.3.5 Reference must be provided for all the geological and hydrogeological information which was researched.119.4 Surface water information.119.4.1 Each Project Development Report shall contain a description of the surface waters in the proposed site and adjacent area, including the name of the watershed which will receive any water discharges, the location of all surface water bodies such as streams, lakes, ponds, and descriptions of major surface drainage systems within the proposed permit area and adjacent areas.119.4.2 Each Project Development report shall also include a plan to manage runoff and control erosion during the lifetime of the facility.
