SECTION 252:606-8-3. Sludge (biosolids) management plan

(a)   All sludge management plans shall be submitted with the permit application and include the following:

(1)   a breakdown of the anticipated types and volumes of biosolids generated;

(2)   daily generation and annual production of semi-solids, solids as total volume and percent solids converted to dry tons;

(3)   laboratory analysis including TCLP reports showing whether the biosolids are hazardous and the chemical and physical properties of biosolids to be land applied including concentrations of metals (listed and other), and any other pollutants;

(4)   the amount of biosolids from each source expected to be used or disposed during each year of operation;

(5)   a description of treatment methods including pathogen treatment and vector attraction reduction, including plant operational controls and record-keeping forms that document biosolids treatment;

(6)   irrigation practices, if any; and

(7)   a demonstration that the biosolids shall not be stored for greater than six (6) months without prior written approval from the DEQ, and in no case longer than one (1) year, prior to use, land application or disposal.

(b)   In addition to the requirements listed in subsection (a) above, Class A sludge management plans must be submitted with the following additional information:

(1)   the proposed schedule for the laboratory analysis to determine the presence or absence of fecal coliform or salmonella;

(2)   the amount of Class A biosolids expected to be generated and produced each year;

(3)   proposed application process for the Class A biosolids;

(4)   a list of proposed uses for the Class A biosolids;

(5)   whether the Class A biosolids will be made available to the general public;

(6)   a fact sheet describing the proper uses and agronomic rates of the Class A biosolids that shall be distributed when the general public is receiving the Class A biosolids; such fact sheets shall not be required when the generator itself uses the Class A biosolids;

(7)   description of the storage of the Class A biosolids until used or distributed; and

(8)   a fact sheet describing the appropriate best management practices for the use of the Class A biosolids that are received from the generator.

(c)   In addition to the requirements listed in subsection (a) above, Class B sludge management plans must be submitted with the following additional information:

(1)   information on how biosolids will be transported from the point of generation to the use, land application or disposal site, including transfer and storage information and a map showing the location of sources of the biosolids, proposed transportation routes, and the location of related containment, storage, and transfer facilities;

(2)   the amount of biosolids from each source expected to be used or disposed during each year of operation;

(3)   identification of specific sites and identifying name for each;

(4)   documentation of the applicant's right to use the site, including time restrictions, if any;

(5)   land use descriptions of adjacent property;

(6)   finding description(s), legal description(s), and latitude and longitude of each site;

(7)   distance to nearest residence;

(8)   topography of the site;

(9)   soil types, permeability, infiltration and drainage patterns;

(10)   proposed methods of field types, tillage, crop types and patterns, crop utilization, expected yield and final use of crop;

(11)   depth to groundwater, including highest seasonal groundwater level, and any other data available;

(12)   records of previous land application conducted at the site, including data on the cumulative metal loading;

(13)   results of any sampling, analyses or monitoring previously performed by the applicant at the site, including metal and nutrient assessment, based on an annual and lifetime use;

(14)   access controls;

(15)   narrative description of buffer zones and other methods to be used to control surface drainage, stormwater runoff, and erosion at each site;

(16)   documentation demonstrating how the biosolids will be incorporated into the soil before the end of each working day;

(17)   documentation that the biosolids will not be land applied within two (2) feet of the highest seasonal water table nor applied to the land within one hundred (100) feet of a stream or body of water;

(18)   documentation that the biosolids will not be land applied within two hundred fifty (250) feet of a public or private water supply;

(19)   equipment to be used;

(20)   narrative description of proposed land application method and related details including depth and frequency of incorporation or injection;

(21)   estimated application rate, frequencies, rest periods between applications, and estimated life of the site. Include calculations on which estimates are based for cumulative metal loading rates;

(22)   emergency response plan describing the actions to be taken by the applicant, including notice for corrective action and remediation associated with spills and releases;

(23)   NRCS soil map of each specific site which shows soil classification, suitability, and soil profiles to a depth of sixty (60) inches;

(24)   highway map which shows the location of each specific site as relative to communities, cities, towns, schools, highway access roads and airports;

(25)   quadrangle topographic map or maps that is an original U.S.G.S. 7.5 minute series (or 15 minute series if the 7.5 series has not yet been printed) with the following clearly marked:

(A)   boundary of the site;

(B)   public water supply sources and treatment facilities;

(C)   pipelines and utility easements;

(D)   oil or gas wells or drilling sites;

(E)   wellhead delineation areas;

(F)   groundwater flow direction;

(G)   waters of the state with special emphasis for "scenic rivers";

(H)   parks, recreation areas and any government owned land dedicated for special purposes (for example, wildlife refuges);

(I)   identification of the 100-year flood plain or floodway if it affects the proposed site;

(J)   any area inhabited by an endangered or threatened wildlife or plant species listed under Section 4 of the federal Endangered Species Act, 16 U.S.C. 1533(c); and

(K)   any additional information determined necessary by the DEQ.
