Section 7103-150.0 - Application for a Storage Permit

Applications for permits to store sludge shall include the following information:

150.1 Written permission from the landowner or landowners and evidence of zoning approval as required by 7 Del.C. § 6003(c) and Section 1100 of these regulations.

150.2 Results of a laboratory analysis of a representative sample of the sludge which was obtained not more than 6 months before submission of the application. The analysis shall include, as a minimum, the metals and nutrients parameters found in Section 115.0 of these regulations. The Department may require more frequent analyses and analyses for other sludge constituents if considered necessary to adequately assess the potential public health and environmental impacts of the project.

150.3 A site specific topographic map of sufficient scale to include:

150.3.1 The areal extent of the site;

150.3.2 The property boundaries;

150.3.3 The size and location of the storage facility;

150.3.4 The location of any streams, springs, or seeps in the area;

150.3.5 The residences or buildings on the site or bordering on the site;

150.3.6 Any roads on the site;

150.3.7 The location of any wells on the site or within 1/2 mile of the site; and

150.3.8 The location of all soil tests, soil borings, or test pits (attach test results).

150.4 A tax map of the site showing the owner's name, site acreage, and property identification number.

150.5 Evidence showing the frequency of flooding at the site based on available flood maps and other information along with an evaluation of stormwater management for the facility.

150.6 The source and volume of sludge to be stored.

150.7 Design volume calculation.

150.8 For facilities constructed of earthen material, and for facilities constructed or installed below grade, the following information shall be submitted:

150.8.1 Soil permeability test results both on the soil used to construct side slopes and at the proposed depth of the facility.

150.8.2 Representative test borings or test pits on the site, to include a description of the texture, color, and evidence of mottling of the soils encountered, and the depth to the ground water. The interpretation of test pit or boring information shall be made by a qualified person.

150.9 Evidence showing the maximum seasonal high ground water elevation.

150.10 The specifications of any liners or soil sealants, if required.

150.11 Detailed construction specifications.

150.12 Method of restricting public access to the site.

150.13 An operations plan to include a description of all sludge handling equipment, daily operating procedures, days and hours of operation, an odor and nuisance control plan, emergency plans, and recordkeeping procedures.

150.14 A description of the truck cleaning facility.

150.15 For permanent facilities constructed of earthen materials, or for facilities constructed or installed below grade, the following information shall be submitted:

150.15.1 Adequate test boring logs, at a minimum of three per 10 acres. These shall be specific as to the soil, sediment, and rock types encountered, depth of groundwater at completion and at 24, 48, and 72 hours after completion, and depth of auger refusal, if applicable. The location of each boring shall be accurately mapped.

150.15.2 Description of the geology at the site, including a discussion of the geologic formations directly involved, the present and future use of these formations as a ground water source and their relationship to underlying formations, providing cross sections based on the information compiled from borehole data.

150.15.3 Hydraulic characteristics of the site, including a ground water contour map, superimposed on a topographic map, showing the location of the water table and the direction and rate of ground water flow, a discussion of the infiltration capacity of surface soils, and the percolation capacity of subsurface soils.

150.15.4 A proposed ground water monitoring program consisting of at least three wells, one upgradient and two downgradient of the facility.

150.15.5 A sediment and erosion control plan for the site.

150.16 For manufactured facilities, the following information shall be submitted:

150.16.1 Information on the structural materials to be used;

150.16.2 Design specifications, such as structural capacity, maximum load, restrictions on use, and dimensions;

150.16.3 Installation or construction techniques and procedures;

150.16.4 A plan for cleaning and periodic inspection of the facility for leaks or other structural defects;

150.16.5 A contingency plan for repairs of the facility, if necessary.

150.17 For above ground enclosed facilities, a plan for controlling emission gases.

150.18 Other relevant information requested by the Department.
