Section 61-107.15.G - Class IV Solid Waste for Land Application/Reclamation

Class IV solid wastes are those solid wastes used for land reclamation and other projects when the application rate exceeds ten (10) dry tons per acre per year and scientific/technical data is submitted to document that the proposed application rate will have no detrimental impact on the environment and public health, and is non-toxic to plants and wildlife normally associated with the crop ecosystem. Solid wastes used in land reclamation and other projects when the application rate is less than ten (10) dry tons per acre per year shall be classified as either Class I or III, as appropriate.

1. The generator of the Class IV 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/reclamation operations.

2. A permit for land application of a Class IV 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 IV 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 7.5 minute quadrant map (U.S. Geological Survey topographic map, including the legend and name of the quadrant) with the proposed application site(s) identified;

c. A site plan on a scale of four (4) inches per mile for each application site. This map shall at a minimum identify the following:

(1) Location of surface water bodies, dry runs, wetlands, the location of the 100-year flood plain boundaries, and other applicable details regarding the general topography of the application site and immediately adjacent properties;

(2) Land use immediately adjacent to the boundaries of the proposed site to demonstrate compliance with buffer requirements including the location of all homes, schools, hospitals, recreational park areas, drinking water wells, and roads;

(3) Restricted or excluded areas; and,

(4) Proposed temporary storage area(s);

d. 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 that 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:

(a) Total alkalinity;

(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;

e. 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.)

(1) pH;

(2) Lime requirement; and,

(3) Available phosphorus and potassium.

f. 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 following information shall be submitted to the Department for approval:

a. A 7.5 quadrant map as outlined in Section G.3.b. above.

b. A site plan as outlined in Section G.3.c. above.

c. A soil test from each application site as outlined in Section G.3.e. above; and,

d. An application plan as outlined in Section G.3.f. above.

5. Unless otherwise defined in the Department permit, the boundary of a Class IV solid waste application shall not extend closer than:

a. One hundred (100) feet of any property line. Variances may be requested and granted on a case-by-case basis upon submittal of written consent from the adjacent landowner(s).

b. One hundred (100) feet of any residence;

c. Five hundred (500) feet of any school, day-care center, hospital or recreational park area;

d. One hundred (100) feet of any surface water body; and,

e. One hundred (100) feet of drinking water wells.

6. Class IV application rates will be reviewed on a case-and site-specific basis. Such projects will be considered if accompanied by appropriate soil and crop monitoring 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 Class IV projects shall be assembled into a technical report and shall be submitted to the Department at the end of the project.

7. 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	4 lbs/acre; readily soluble boron as determined by hot water extraction
sulfate	300 lbs/acre
sodium	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.

c. The anticipated date to begin application activities; and,

d. The anticipated duration of the application activities.

12. The temporary storage of Class IV solid wastes at the application site shall be limited to the amount designated for use at that location, and shall comply with the criteria outlined below if storage exceeds forty-eight (48) hours.

a. Temporary storage at the application site shall not exceed two (2) weeks;

b. Earthen dikes, berms or other suitable barriers shall be constructed around the perimeter of the storage area to minimize off-site movement of the waste materials;

c. Monitoring wells around the perimeter of the storage area may be required upon written notification from the Department on a case-by-case basis based on consideration of the type of waste, the amount of solid waste to be stored, topography of the land, and the potential impact to groundwater, etc. Any analyses required shall be performed by a Certified Laboratory; and,

d. Temporary storage locations shall be reclaimed within thirty (30) days of construction by re-establishing the original groundline, incorporating into the soil any small amounts of residual materials by disking or plowing and revegetating the area for soil stabilization.

13. Monitoring Requirements for Class IV 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 G.3.d. (1) of this regulation performed by a Certified Laboratory and those parameters listed in Section G.3.d. (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.
