SECTION 252:616-11-7. Sludge Management Plans

  Any facility that produces and land applies industrial sludge must develop and submit to the DEQ for approval a sludge management plan. This section does not apply to the land application of drilling wastes from oil and gas production or salt water disposal facilities under the jurisdiction of the Oklahoma Corporation Commission. A sludge management plan must include the following:

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

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

(3)   laboratory analysis showing whether the industrial sludge is hazardous and the chemical and physical properties of industrial sludge to be land applied including concentrations of metals (listed and other), and any other pollutants. A TCLP need only be conducted once a year, unless there is a change in the process for the development of the industrial sludge;

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

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

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

(7)   land use descriptions of adjacent property;

(8)   finding descriptions, legal descriptions, and latitude and longitude of each site;

(9)   distance to nearest residence;

(10)   topography of the site;

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

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

(13)   irrigation practices, if any;

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

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

(16)   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;

(17)   access controls;

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

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

(20)   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;

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

(22)   quadrangle topographic map or maps that is an original U.S.G.S. 7.5 minutes 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.
