Current through Register Vol. 48, No. 9, September 27, 2024
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:
(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;
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.)
(1) pH;
(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.

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:

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:
