Current through Register Vol. 48, No. 9, September 27, 2024
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;

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.)

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.

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.
14. Reporting Requirements. Generators of
Class IV solid waste that is land applied shall submit to the Department and to
the landowner, 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 the information outlined below. This information shall be maintained by
the generator for a period not less than ten (10) years.
a. Any chemical analyses of the wastes
performed during the reporting period subsequent to the original data submitted
with the permit application request;
b. Any soil analyses performed during the
reporting period subsequent to the original data submitted with the permit
application request;
c. Application
Site Information. The following information shall be included in the annual
report:
