Section 61-107.15.D - Class I Solid Waste for Land Application (eg, coal ash, wood ash, green liquor dregs, slaker grit)1. The generator of the Class I solid waste shall obtain a permit from the Department for the land application of the specific waste(s) at proposed location(s) prior to commencing land application operations.2. A permit for land application of a Class I solid waste shall be reviewed by the Department on an annual basis.3. A request for a Department permit for the land application of a Class I solid waste shall include, but not be limited to, the following: a. A completed permit application on a form provided by the Department;b. A county map(s) showing the location of the proposed application site(s);c. A chemical analysis (representative analysis) of the waste material to be land applied. This chemical analysis shall be conducted on samples collected within the last three (3) months and include the parameters listed below. This sample shall be a representative sample of the waste material to be applied. New representative samples shall be analyzed if there are changes in fuel source, process operations, or other changes which would alter the chemical characteristics of the waste. The frequency of sampling and the number of sample analyses needed to establish a representative analysis will vary according to the uniformity and consistency of the waste. At a minimum, the determination of representative analysis shall be reassessed each year but shall be sufficiently frequent and extensive so as to comply with Section B.29 of this regulation, the definition for "representative sample and representative analysis". (1) The following parameters shall be analyzed by a South Carolina Certified Laboratory certified for these parameters: (b) Concentrations of the following metals: arsenic | cadmium |
copper | lead |
mercury | nickel |
selenium | zinc |
(c) Total Keldjahl nitrogen, nitrate-nitrogen, and ammonium-nitrogen;(2) The following parameters shall be analyzed by an Agricultural Laboratory:(a) Electrical conductivity of a saturated extract; and,(b) Soluble boron, sodium, and sulfate; d. A soil test from each proposed application site performed by an Agricultural Laboratory for agricultural purposes shall be submitted to the Department unless specifically exempted in the Department permit. The soil sample(s) shall be representative of the field(s) to which the waste will be applied. The soil sample shall be collected subsequent to the most recent application of fertilizer, lime, and other material which would alter the soil test results but no more than six (6) months prior to submittal of the data. This analysis shall include a recommendation for lime and plant nutrients needed or appropriate for good crop or forest production purposes based on Best Management Practices (BMPs) and the parameters listed below. (BMPs are available from the State Extension Service, various governmental agencies involved in management of agricultural, silvicultural or horticultural lands, Certified Crop Advisers, registered foresters, soil scientists, and agronomists.) (2) Lime requirement; and,(3) Available phosphorus and potassium.e. An application plan detailing: (1) Rates to be applied at each location, expressed on an areal application basis;(2) Cropping plan and proposed schedule for each application;(3) Application method and safeguards to limit soil loss; and,(4) Equipment to be used for uniform application. 4. To add additional application sites to the permit, the generator shall request a permit modification prior to application. The information listed below shall be submitted to the Department for approval. A variance of Item 4.b. and 4.c. below may be requested once a compliance history is established. Variances will be based on past compliance history, the consistency of the waste stream, the consistency of the soils, the consistency of crops, and submittal of scientific data to document that the application program will have no adverse impact on the environment and public health, and is non-toxic to plants and wildlife normally associated within the crop ecosystem. a. A county map(s) showing the location of each proposed application site;b. A soil test from each application site as outlined in Section D.3.d. above; and,c. An application plan as outlined in Section D.3.e. above.5. Class I Application Rates:a. Unless otherwise approved by the Department, application rates for Class I solid wastes shall not exceed ten (10) dry tons per acre per year on cultivated crop or forest lands or five (5) dry tons per acre per year on pasture land in which the waste is not incorporated into the soil surface layer unless otherwise limited to a lower rate by soil test recommendation, agronomic rate, or metal loading. For example, nitrogen, boron, sodium, or soluble salts content and alkalinity may limit application rate to less than ten dry tons per acre per year; and,b. Requests for application rates exceeding the limits outlined above will be reviewed on a case-and site-specific basis. Such projects may be considered if accompanied by appropriate soil and crop monitoring data for purposes of establishing relationships between soil physical characteristics and solid waste application rates, or relationships between long term, repeated applications and mobility or plant availability of elemental constituents of the solid waste or chemical processes in soil. Monitoring data obtained from such projects shall be assembled into a technical report and submitted to the Department. Requests for changes in application plans or locations shall be submitted in writing to the Department for review, consideration, and approval.6. The following potential rate limiting factors shall establish the amount of waste that may be land applied. The application of waste shall not cause the soil pH to significantly fall below or rise above the range indicated. In addition, the application of waste shall not add more than the indicated amount of soluble sulfate, sodium, or boron. Nutrient limits are those recommended by the Clemson Cooperative Extension Service. FACTOR | CONSTITUENT | LIMIT |
pH (soil) | The application of waste shall not cause the soil pH to significantly fall below or rise above the range of 5.0 to 7.0. |
Soluble Salts: | boron sulfate sodium | 4 lbs/acre; readily soluble boron as determined by hot water extraction 300 lbs/acre Less than 15% of base saturation of soil |
Plant Nutrients: | Agronomic crops - consult Circular 476, Cooperative Extension Service, Clemson University, Clemson, 1982. The recommendations for nitrogen, phosphorus, and potassium are provided with agricultural soil tests. In addition, recommendations may be obtained from the local County Extension Office, a Certified Crop Adviser, an agronomist or soil scientist, or the Faculty of Soils at Clemson University. Silvicultural sites - recommendation for nitrogen and other nutrients may be obtained from the Forest Resources Department at Clemson University, Area County Extension Agents for Forestry, or professional foresters with training in nutrient management. |
Metals | As specified in Section C.13 of this regulation. |
7. Unless otherwise approved by the Department, Class I solid waste may be applied to the same location more frequently than once each year as long as the total amount applied in any 12-month period does not exceed ten (10) dry tons per acre, if one of the factors cited above relating to agronomic rate or metal loading does not otherwise limit the loading rate.8. No less than twenty-four (24) hours prior to land application of a Class I solid waste at an approved location, the generator shall notify the Department's EQC District Office and provide the following information:a. The location to receive the application;b. An estimate of the volume of waste to be land applied during the project;c. The anticipated date to begin application activities; and,d. The anticipated duration of the application activities.9. Monitoring Requirements for Class I Solid Waste.a. Solid Waste. Annually, or more frequently if necessary to document the waste concentration within a tolerance of +-25%, a new chemical analysis of a representative sample of the solid waste shall be submitted to the Department with the annual report. If there are substantive changes in fuel source, process operations, or other changes which would alter the chemical characteristics of the waste, additional sampling shall be required at that time. This analysis shall include the parameters listed in Section D.3.c. (1) of this regulation performed by a Certified Laboratory and those parameters listed in Section D.3.c. (2) performed by an Agricultural Laboratory.b. Soil Analyses. Prior to a subsequent application of the solid waste, soil samples shall be analyzed by a Certified Laboratory for whichever constituent(s) or parameter(s) limited the previous application. The soil sample from pastures shall be taken from the surface 2-3 inches. Samples from cultivated fields and forested landscapes shall be taken from the surface 6 inches. If nitrogen was the limiting constituent, the soil sample shall be taken to a depth of 4 feet and divided into five subsamples (0-6, 6-12, 12-24, 24-36, and 36-48 inches) for analysis of ammonium-nitrogen and nitrate-nitrogen.10. Reporting Requirements. Generators of Class I solid waste that is land applied shall maintain and report the information as outlined below. a. The generator shall submit to the Department the following information in the form of an annual report for the period of July 1 through June 30. This report shall be submitted to the Department on or before August 15th and shall include: (1) Any chemical analyses of the wastes performed during the reporting period subsequent to the original data submitted with the permit application request;(2) Soil analyses for all locations that received an application of solid waste subsequent to the application of the amount of waste approved for the initial 12-month period, pursuant to Section D.9.b. above; and,(3) The total amount of solid waste in tons land applied during the reporting period; and,b. The generator shall maintain on site the following application site information and shall submit to the Department upon request:(1) Location of the site(s) that received solid waste applications during the reporting period;(2) Amount of solid waste applied to each site;(3) Number of acres treated at each site;(4) Date of application(s) at each site; and,(5) The crop being grown on the application site.S.C.
