Permit No. SC0001333

PART I. Definitions

Any term not defined in this Part has the definition stated in the Pollution Control Act or in “Water Pollution Control Permits”, R.61-9 or its normal meaning.

A. The “Act”, or CWA, shall refer to the Clean Water Act (Formerly referred to as the Federal Water Pollution Control Act) Public Law 92-500, as amended.

B. “Agricultural land” is land on which a food crop, a feed crop, or a fiber crop is grown. This includes range land and land used as pasture.

C. “Agronomic rate” is the application rate designed:

1. To provide the amount of nitrogen needed by the food crop, feed crop, fiber crop, cover crop, or vegetation grown on the land.

2. To minimize the amount of nitrogen in the industrial sludge that passes below the root zone of the crop or vegetation grown on the land to the groundwater; and

3. To provide the amount of other or ganic and inorganic plant nutrients th at promote crop or vegetation growth, such as calcium carbonate equivalency.

D. “Annual pollutant loading rate” is the maximum amount of a pollutant that can be applied to a unit area of land during a 365 day period.

E. “Annual whole sludge application rate” is the maximum amount of industrial sludge (dry weight) that can be applied to a unit area of land during a 365 day period.

F. “Application frequency” means the number of days per week that wastewater or sludge is applied to the land.

G. “Application period” means the length of time per day that wastewater or sludge is applied to the land.

H. The “arithmetic mean” of any set of values is the su mmation of the individual values divided by the number of

individual values.

I. “Background groundwater analysis” means the chemical or biological quality of groundwater before application of wastewater or sludge, or the groundwater chemistry or biological quality of up-gradient to the site of concern.

J. “Bulk industrial sludge” is industrial sludge that is not sold or given away in a bag or other container for application to the land.

K. “Bypass” means the intentional diversion of waste streams from any portion of a treatment facility.

L. A “composite sample” shall be defined as one of the following four types:

1. An influent or effluent portion collected continuously over a specified period of time at a rate proportional to

the flow.Part I Page 4 of 40

Permit No. SC0001333

2. A combination of not less than 8 infl uent or effluent grab samples collected at regular (equal) intervals over a specified period of time and composited by increasing th e volume of each aliquot in proportion to flow. If continuous flow measurement is not used to compos ite in proportion to flow, the following method will be

used: An instantaneous flow measurement should be take n each time a grab sample is collected. At the end of the sampling period, the instantaneous flow measuremen ts should be summed to obtain a total flow. The instantaneous flow measurement can then be divided by the total flow to determine the percentage of each grab sample to be combined. These combined samples form the composite sample.

3. A combination of not less than 8 influent or effluent grab samples of equal volume but at variable time intervals that are inversely proportional to the volume of the flow. In other words, the time in terval between aliquots is

reduced as the volume of flow increases.

4. If the effluent flow varies by less than 15 percent, a combination of not less than 8 influent or effluent grab samples of constant (equal) volume collected at regular (equal) time intervals over a specified period of time.

All samples shall be properly preserved in accordance with Part II.J.4. Continuous flow or the sum of instantaneous flows measured and averaged for the specified compositi ng time period shall be used with composite results to

calculate mass.

M. “Cover crop” is a small grain crop, such as oats, wheat, or barley; grasses or other crop grown for agronomic uses.

N. “Cumulative pollutant loading rate” is the maximum amount of an inorganic pollutant that can be applied to an

area of land.

month.

P. “Daily minimum” is the lowest average value recorded of samples collected on any single day during the calendar

month.

Q. The “Department” shall refer to the South Carolin a Department of Health and Environmental Control.

R. “Down gradient” means the portion of the water table th at is down the hydraulic slope of the water table with respect to a specific area or point of reference.

S. “Dry weight basis” means calculated on the basis of having been dried at 105 degrees Celsius until reaching a constant mass (i.e., essentially 100 percent solids content).

T. “Feed crops” are crops produced primarily for consumption by animals.

U. “Fiber crops” are crops such as flax and cotton.

V. “Food crops” are crops consumed by humans. These include, but are not limited to, fruits, vegetables, and tobacco.

W. “Forest” is a tract of land thick with trees and underbrush.Part I Page 5 of 40

Permit No. SC0001333

X. The “geometric mean” of any set of values is the Nth r oot of the product of the individual values where N is equal to the number of individual values. The geometric mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual values. For purposes of calcu lating the geometric mean, values of zero (0) shall be considered to be one (1).

Y. A “grab sample” is an individual, disc rete or single influent or effluent portion of at least 100 milliliters collected at a time representative of the discharge and over a period not exceeding 15 minutes and retained separately for analysis. Instantaneous flow measured at the time of grab sample collection shall be used to calculate quantity,

b. Unless addressed elsewhere in this permit, the pe rmittee shall use a sufficiently sensitive analytical method that achieves a value below the derived permit limit stated in Part III. If more than one method of analysis is approved for use, the Department r ecommends for reasonable poten tial determinations that the permittee use the method having the lowest practical quantitation limit (PQL) unless otherwise specified in Part V of the permit. For the purposes of reporting analytical data on the Discharge Monitoring Report (DMR):

(1) Analytical results below the PQL conducted usi ng a method in accordance with Part II.J.4.a above shall be reported as zero (0). Zero (0) shall al so be used to average results which are below the PQL. When zero (0) is reported or used to av erage results, the permittee shall report, in the

“Comment Section” or in an attachment to the DMR, the analytical method used, the PQL achieved, and the number of times results below the PQL were reported as zero (0).

(2) Analytical results above the PQL conducted using a method in accordance with Part II.J.4.a shall be reported as the value achieved. When averaging resu lts using a value containing a “less than,” the average shall be calculated using the value and reported as “less than” the average of all results

collected.

(3) Mass values shall be calculated using the flow taken at the time of the sample and either the concentration value actually achieved or the value as determined from the procedures in (1) or (2) above, as appropriate.

5. The Clean Water Act provides that any person who fals ifies, tampers with, or knowingly renders inaccurate any monitoring device or method required to be main tained under this permit shall, upon conviction, be punished by a fine of not more than $10,000 or by impris onment for not more than 2 years, or both. If a conviction of a person is for a violation committed after a first conviction of such person under this paragraph, punishment is a fine of not more than $20,000 per day of violation, or by imprisonment of not more than 4 years, or both.
