Part IX

Wastewater General Permit SCG570034

3. No permittee may cause, allow, or permit emission into the ambient air of any substance or combinations of substances in quantities that an undesirable level of odor is determined to result unless preventative measures of the type set out below are taken to abate or control the emission to the satisfaction of the Department. When an odor problem comes to the attention of the

Department through field surveillance or specific complaints, the Department may determine, in accordance with section 48-1-120 of the Pollution Control Act, if the odor is at an undesirable level by considering the character and degree of injury or interference to:

a. The health or welfare of the people;

b. Plant, animal, freshwater aquatic, or marine life;

c. Property; or

d. Enjoyment of life or use of affected property.

4. After determining that an undesirable level of odor exists, the Department may require:

a. the permittee to submit a corrective action plan to address the odor problem,

b. remediation of the undesirable level of odor within a reasonable timeframe, and

c. in an order, specific methods to address the problem.

5. In accordance with R.61-9.503.50(e), if the permittee fails to control or abate the odor problems addressed in this section within the specified timeframe, the Department may revoke disposal/application activities associated with the site or the specific aspect of the sludge management program.

E. [Reserved]

F. [Reserved]

G. Additional Operational Requirements

1. The wastewater treatment plant is assigned a classification of Group III-Biological. This classification corresponds to an operator with a grade of B or higher.

2. The wastewater treatment plant is assigned a Reliability Classification of I, in accordance with

Section 67.400 "Reliability Classifications" of the Standards for Wastewater Facility

Construction: R.61-67.

3. For parameters with a sample frequency of once per month or greater, the Permittee shall monitor

(at least one sample) consistent with conditions established by this Permit on the 1 st Monday of every calendar month, unless otherwise approved by the Department. (For example; with a once

Part IX per week (01/07) sampling frequency, the permittee shall monitor one weekly sample on the day of the week noted during the monthly DMR reporting period.)

For parameters with a sampling frequency of less than once per month (if any), the permittee shall monitor these parameters on specific date noted above on any of the months during the appropriate reporting period unless otherwise approved by the Department. (For example, with a once per quarter (1/90) sampling frequency, the permittee may monitor on the day of the week noted in either the first, second or third month in the quarterly reporting period.)

For parameters requiring multiple samples for a single test the Permittee may collect the samples on any date during the reporting period, unless otherwise approved by the Department. The permittee must notify the Department of the planned sampling dates upon request.

In accordance with R.61-9.122.41(j)(1)(iii), the Department may waive compliance with the permit requirement for a specific sampling event for extenuating circumstances. Additional monitoring, as necessary to meet the frequency requirements of this Permit (Part IV, if applicable) shall be performed by the Permittee.

4. Wastewater Design Flow

a. For the purposes of identification of the treatment capacity (under R.61-67.300.A.8) the design flow is 0.01 MGD.

b. For NPDES billing (under R.61-30.B(2)(b)), the “actual flow” limit for this wastewater treatment facility shall be identified as the design flow of 0.01 MGD.

5. Water Treatment Plant Notification

The permittee shall notify any downstream water treatment plants within fifteen (15) miles downstream of any emergency condition, plant upset, bypass or other system failure, which has the potential to affect the quality of water withdrawn for drinking purposes:

This notification should be made as soon as possible and in anticipation of such event, if feasible, without taking away any response time necessary to attempt to alleviate this situation.

6. Sludge transportation and disposal requirements, if applicable, shall hereby be incorporated by reference into this permit from the attached “Sludge Removal and Transportation Approval” letter.

Part I

0BPart I. DEFINITIONS

Any term not defined in this Part has the definition stated in the South Carolina Pollution Control Act

(PCA) 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 means the Clean Water Act (formerly referred to as the Federal Water Pollution Control Act or Federal Water Pollution Control Act Amendments of

1972) Pub. L. 92-500, as amended by Pub. L. 95-217, Pub. L. 95-576, Pub. L. 96-483, and Pub. L.

97-117, 33 U.S.C. 1251 et seq. Specific references to sections within the CWA will be according to

Pub. L. 92-500 notation.

B. “ UArithmetic MeanU” for any set of values means the summation of the individual values divided by the number of individual values.

C. “ UBest Management Practices U” (“BMPs”) means schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the pollution of waters of the United States. BMPs also include treatment requirements, operating procedures, and practices to control facility site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.

D. “ UBypass U” means the intentional diversion of waste streams from any portion of a treatment facility.

E. “ UComposite sample U” 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.

2. A combination of not less than 8 influent or effluent grab samples collected at regular (equal) intervals over a specified period of time and composited by increasing the volume of each aliquot in proportion to flow. If continuous flow measurement is not used to composite in proportion to flow, the following method will be used: An instantaneous flow measurement should be taken each time a grab sample is collected. At the end of the sampling period, the instantaneous flow measurements 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 interval between aliquots is reduced as the volume of flow increases.

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

5. All samples shall be properly preserved in accordance with Part IV.B.4. Continuous flow or the sum of instantaneous flows measured and averaged for the specified compositing time period shall be used with composite results to calculate mass.

F. “ UCWAU” means Clean Water Act. See A. above.

G. “ UDaily discharge U” means the discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. For pollutants with limitations expressed in units of mass, the daily discharge is calculated as the total mass of the pollutant discharged over the day. For pollutants with limitations expressed in other units of measurement, the daily discharge is calculated as the average measurement of the pollutant over the day.

H. “ UDaily maximumU” other than for bacterial indicators (i.e. fecal coliform, E. coli and enterococci) is the highest average value recorded of samples collected on any single day during the calendar month.

Daily average for bacterial indicators means the highest arithmetic average of bacterial samples collected for each bacterial indicator species (i.e. fecal coliform, E. coli and/or enterococci) in any 24 hour period during a calendar month.

I. “ UDaily minimumU” is the lowest average value recorded of samples collected on any single day during the calendar month.

J. “ UDepartmentU” or “DHEC” means the South Carolina Department of Health and Environmental

Control or an authorized representative.

K. “ UDirectorU” means the EPA Regional Administrator or an authorized representative.

L. “ UDMRU” means a Discharge Monitoring Report.

M. “ UEPAU” means the Environmental Protection Agency.

N. “ UFreshwaterU” means any freshwater as defined by Regulation 61-68 and classified by Regulation 61-

69.

O. “ UGeometric mean U” of any set of values is the Nth root 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 calculating the geometric mean, values of zero (0) shall be considered to be one (1).

P. “ UGrab sample U” is an individual, discrete 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, unless a totalizer is used.

Q. “ UInstantaneous maximum or minimumU” means the highest or lowest value recorded of all samples collected during the calendar month.

R. “ UMGDU” means million gallons per day.

S. "UMonthly Average U", other than for fecal coliform, E. coli and enterococci, is the arithmetic mean of all samples collected in a calendar month period. Monthly average (for bacterial indicators only) means the calendar month (i.e., 28 days, 29 days, 30 days, or 31 days) geometric mean of all bacterial samples collected [for each of the bacterial indicator species (i.e., E. coli, enterococci, and/or fecal coliform)] during that calendar month. The monthly average loading is the arithmetic average of all daily discharges made during the month.

T. “ UNOIU” means notice of intent to be covered by this permit.

U. “ UNOTU” means notice of termination.

V. “ UOutfallU” or “UPoint SourceU” means any discernible, confined, and discrete conveyance, including but not limited to, any pipe, ditch, channel, tunnel, conduit, discrete fissure, container, rolling stock, concentrated animal feeding operation, landfill leachate collection system, or vessel or other floating craft from which pollutants are or may be discharged. This term does not include return flows from irrigated agricultural or agricultural storm water runoff.

W. “ UPermitteeU” means any individual, facility or company to whom this permit has been issued.

X. “ UPOTWU” means a treatment works as defined by section 212 of the CWA, which is owned by a state or municipality (as defined by section 502[4] of the CWA). This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal sewage or industrial wastes of a liquid nature or a regional entity composed of two (2) or more municipalities or parts thereof. It also includes sewers, pipes and other conveyances only if they convey wastewater to a

POTW Treatment Plant. The term also means the municipality, as defined in section 502[4] of the

CWA, which has jurisdiction over the Indirect Dischargers to and the discharge from such a treatment works.

Y. “ UPractical Quantitation LimitU” is the concentration at which the entire analytical system must give a recognizable signal and acceptable calibration point. It is the concentration in a sample that is equivalent to the concentration of the lowest calibration standard analyzed by a specific analytical procedure, assuming that all the method-specific sample weights, volumes, and processing steps have been followed. It is also referred to as the reporting limit.

Z. “ UPrivately owned treatment works U” means any device or system which both is used to treat wastes from any facility whose operator is not the operator of the treatment works and is not a POTW.

AA “ UQuarterU” is defined as the first three calendar months beginning with the month that this permit becomes effective and each group of three calendar months thereafter.

BB. “ UQuarterly average U” is the arithmetic mean of all samples collected in a quarter.

CC. “ URegional AdministratorU” means the Regional Administrator of Region IV of the Environmental

The value to be reported is the single highest of the four (4) weekly averages computed during a calendar month. The weekly average loading is the arithmetic average of all daily discharges made during the week.

NN. “ UUltimate Oxygen Demand U” (UOD) is the oxygen consumed by aquatic microbes in metabolizing the remaining organic and nitrogenous matter in the effluent from the permittee's wastewater treatment plant. This demand is expressed in pounds per day and is calculated by multiplying the effluent biochemical oxygen demand (BOD5) or the effluent carbonaceous biochemical oxygen demand (CBOD5) concentration by the F-ratio and adding that to 4.57 times the effluent ammonia

(NH3-N) concentration and multiplying the sum by the flow and the constant 8.34. The UOD loading is the arithmetic average of all individual loading determinations made during the sampling period.

U.O.D.(lbs/day) = [{BOD5(mg/l) * F-ratio} + {NH3-N(mg/l) * 4.57}] * Flow(MGD)* 8.34

F-ratio = 1.50

OR

U.O.D.(lbs/day) = [{CBOD5(mg/l) * F-ratio} + {NH3-N(mg/l) * 4.57}] * Flow(MGD)* 8.34
