46175 PART I. Definitions

Any term not defined in this Part h as 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. The “average” or “arithmetic mean” of any set of values is the summation of the individual values divided by the

number of individual values.

C. “Basin” (or “Lagoon”) means any in

- ground or earthen structure designed to receive , treat, store, temporarily retain and/or allow for the infiltration/evaporation of wastewater.

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

E. 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.

2. A combination of not less than 8 influent or effluent grab samples collected at regular (equal) inter vals 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 me asurement 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 de termine 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 proportio nal 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 flow varies by less than 15 percent, a combination of not less than 8 influent or effluent grab samples of c onstant (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 sp ecified compositing time period shall be used with composite results to

calculate mass.

F. “Daily discharge” means the discharge of a pollutant measured during a calendar day or any 24

- hour period that reasonably represents the calendar day for purposes o f 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 disch arge is calculated as the average measurement of the pollutant over the day.Part I Page 4 of 24

Permit No. SC00 46175

Part III Page

4 of 24 Permit No. SC00

46175 G. “Daily maximum” is the highest average value recorded of samples collected on any single day during the calendar

month.

H. “Daily minimum” is the lowest average value recorde d of samples collected on any single day during the calendar

month.

I. The “Department” or “DHEC” shall refer to the South Carolina Department of Health and Environmental Control.

J. The “geometric mean” of any set of values is the Nth root of the produc t 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 ze ro (0) shall be considered to be one (1).

K. A “grab sample” 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 r etained separately for analysis.

L. “Groundwater” means the water below the land surface found in fractured rock or various soil strata.

M. The “maximum or minimum” is the highest or lowest value, respectively, recorded of all samples collected during

t he calendar month. These terms may also be known as the instantaneous maximum or minimum.

N. “Monitoring well” means any well used to sample groundwater for water quality analysis or to measure groundwater levels.

O. The “monthly average”, other than f or fecal coliform and enterococci, is the arithmetic mean of all samples collected in a calendar month period. The monthly average for fecal coliform and enterococci bacteria is the geometric mean of all samples collected in a calendar month period. The monthly average loading is the arithmetic average of all daily discharges made during the month.

P. The “PCA” shall refer to the Pollution Control Act (Chapter 1, Title 48, Code of Laws of South Carolina).

Q. The “practical quantitation limit” (PQL) is t he 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.

R. “Quarter” is defined as the first three calendar months beginning with Janua ry and each group of three calendar months thereafter (also known as calendar quarters).

S. “Quarterly average” is the arithmetic mean of all samples collected in a quarter.

T. “Severe property damage” means substantial physical damage to property, damag e to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production.Part I Page 5 of 24

Part III Page

5 of 24 Permit No. SC00

46175 U. “Sludge” means industrial sludge. Industrial sludge is a solid, semi

- solid, or liquid residue generated during the treatment of industrial wastewater in a treatment works. Industrial sludge includes, but is not limited to, indus trial septage; scum or solids removed in primary, secondary, or advanced wastewater treatment processes; and a material derived from industrial sludge. Industrial sludge does not include ash generated during the firing of industrial sludge in an industria l sludge incinerator or grit and screenings generated during preliminary treatment of industrial wastewater in a treatment works. Industrial sludge by definition does not include sludge covered under 40 CFR

Part 503 or R.61

- 9.503.

V. “Upset” means an exc eptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.

W. “Wastewater” means industrial wastewater. Industrial wastewater is wastewater generate d from a federal facility, commercial or industrial process, including waste and wastewater from humans when generated at an industrial facility.

X. “Weekly average” is the arithmetic mean of all the samples collected during a one

- week period. For self

monitoring purposes, weekly periods in a calendar month are defined as three (3) consecutive seven

- day intervals starting with the first day of the calendar month and a fourth interval containing seven (7) days plus those days beyond the 28th day in a cal endar month. 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.Part II Page 6 of 24

46175 PART II. Standard Conditions

A. Duty to comply

The permittee must comply with all conditions of the permit. Any permit noncompliance constitutes a violation of the Clean Water Act and the Pollution Control Act and is grounds for enforcement action; for permit termination,

revocatio n and reissuance, or modification; or denial of a permit renewal application. The Department’s approval of wastewater facility plans and specifications does not relieve the permittee of responsibility to meet permit limits.

1. The permittee shall comply with effluent standards or prohibitions established under section 307(a) of the Clean Water Act for toxic pollutants and with standards for sewage sludge use or disposal established under section 405(d) of the CWA within the time provided in the regulation s that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if the permit has not yet been modified to incorporate the requirement.

2. Failure to comply with permit conditions or the provisions of this permit may subject the permittee to civil penalties under S.C. Code Section 48

- 1

- 330 or criminal sanctions under S.C. Code Section 48

- 1

- 320. Sanctions for violations of the Federal Clean Water Act may be imposed in accordance with the provisions of 40 CFR Part

122.4 1(a)(2) and (3).

3. A person who violates any provision of this permit, a term, condition or schedule of compliance contained within this NPDES permit, or the State law is subject to the actions defined in the State law.

B. Duty to reapply

If the permitt ee wishes to continue an activity regulated by this permit after the expiration date of this permit, the permittee must apply for and obtain a new permit. A permittee with a currently effective permit shall submit a new application 180 days before the exi sting permit expires, unless permission for a later date has been granted by the Department. The Department shall not grant permission for applications to be submitted later than the expiration date of the existing permit.

C. Need to halt or reduce activi ty not a defense

It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.

D. Duty to mitigate

The per mittee shall take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of this permit which has a reasonable likelihood of adversely affecting human health or the environment.

E. Proper operation and maintenance

1. The permittee shall at all times properly operate and maintain in good working order and operate as efficiently as possible all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the terms and conditions of this permit. Proper operation andPart II Page 7 of 24

Part III Page

7 of 24 Permit No. SC00

46175 maintenance includes effective performance based on design facility removals, adequate funding, adequate operator staffing and training and also includes adequate laborat ory controls and appropriate quality assurance procedures. This provision requires the operation of back

- up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the c onditions of the permit.

2. Power Failures. In order to maintain compliance with effluent limitations and prohibitions of this permit, the permittee shall either:

a. provide an alternative power source sufficient to operate the wastewater control facil ities;

b. or have a plan of operation which will halt, reduce, or otherwise control production and/or all discharges upon the reduction, loss, or failure of the primary source of power to the wastewater control facilities.

3. The permittee shall develo p and maintain at the facility a complete Operations and Maintenance Manual for the

waste treatment facilities. The manual shall be made available for on

- site review during normal working hours. The manual shall contain operation and maintenance instructio ns for all equipment and appurtenances associated with the waste treatment facilities and land application system, if applicable. The manual shall contain a general description of the treatment process(es), the operational procedures to meet the requiremen ts of E.1 above, and the corrective action to be taken should operating difficulties be encountered.

4. The permittee shall provide for the performance of daily treatment facility inspections by a certified operator of the appropriate grade as defined in Part V.E of this permit. The Department may make exceptions to the daily operator requirement in accordance with R.61

- 9.122.41(e)(3)(ii). The inspections shall include, but should not necessarily be limited to, areas which require visual observation to de termine efficient operation and for which immediate corrective measures can be taken using the O & M manual as a guide. All inspections shall be recorded and shall include the date, time, and name of the person making the inspection, corrective measures

ta ken, and routine equipment maintenance, repair, or replacement performed. The permittee shall maintain all records of inspections at the permitted facility as required by the permit, and the records shall be made available

for on

- site review during normal working hours.

5. The name and grade of the operator of record shall be submitted to DHEC/Bureau of Water/Water Pollution Control Division prior to placing the facility into operation. A roster of operators associated with the facility's operation and th eir certification grades shall also be submitted with the name of the “operator

- in

- charge.” Any changes in operator or operators shall be submitted to the Department as they occur.

F. Permit actions

This permit may be modified, revoked and reissued, or term inated for cause. The filing of a request by the permittee for a permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any permit condition.

G. Property rights

This permit does not convey any property rights of any sort, or any exclusive privilege nor does it authorize any injury to persons or property or invasion of other private rights, or any infringement of State or local law or regulations.Part II Page 8 of 24

J. Monitoring and records

1. a. (1) Samples and measurements taken for the purpose of monitoring shall be representative of the monitored

activity.

(2) Samples shall be reasonably distributed in tim e, while maintaining representative sampling.

(3) No analysis, which is otherwise valid, shall be terminated for the purpose of preventing the analysis from showing a permit or water quality violation.

b. Flow Measurements.

(1) Where primary flow meters a re required, appropriate flow measurement devices and methods consistent with accepted scientific practices shall be present and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The devices shall be instal led, calibrated and maintained to ensure that the accuracy of the measurements are consistent with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a maximum deviation e discharge rates throughout the range of expected discharge volumes. The primary flow device, where required, must be accessible to the use of a continuous flow recorder.

(2) Where permits require an estimate of flow, the permittee shall maintain at the pe rmitted facility a record of the method(s) used in estimating the discharge flow (e.g., pump curves, production charts, water use records) for the outfall(s) designated on limits pages to monitor flow by an estimate.

(3) Records of any necessary calibrations must be kept.Part II Page 9 of 24

f. The results of such analyses.

4. a. Analyses for required monitoring must be conducted according to test procedures approved under 40 CFR Part 136, equivalent test procedures approved by the Department or other test procedures that have been specified in the permit.

In the case of sludge use or disposal, analysis for required monitoring must be conducted according to test procedures approved under 40 CFR Part 136, test procedures specifi ed in R.61

- 9.503 or R.61

- 9.504, equivalent test procedures approved by the Department or other test procedures that have been specified in the permit.

b. Unless addressed elsewhere in this permit, the permittee shall use a sufficiently sensitive analytic al 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 recommends for reasonable potential determinations that the permittee use the method having the lowes t 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 using a method in accordance wi th Part II.J.4.a above shall be reported as zero (0). Zero (0) shall also be used to average results which are below the PQL. When zero (0) is reported or used to average 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 results 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)(a) The mass value for a pollutant collected using a grab sample shall be calculated using the 24

- hour totalized flow for the day the sample was collected (if available) or the instantaneous flow at the time of the sample and either the concentration value actually achieved or the value as determined from the procedure s in (1) or (2) above, as appropriate. Grab samples should be collected at a time representative of the discharge.Part II Page 10 of 24

oper ation of the regulated facility or activity such as the position of plant manager, operator of a well or a well field, superintendent, position of equivalent responsibility, or an individual or position having overall responsibility for environmental matte rs for the company. (A duly authorized representative may thus be either a named individual or any individual occupying a named position.) and,

(3) The written authorization is submitted to the Department.

c. Changes to authorization. If an authorization under Part II.K.1.b of this section is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, a new authorization satisfying the requirements of Part II.K.1.b of this section must be sub mitted to the Department prior to or together with any reports, information, or applications to be signed by an authorized representative.

d. Certification. Any person signing a document under Part II.K.1.a or b of this section shall make the following c ertification: “I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submi tted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.”

2. The PCA provides that any person who knowingly makes any false statement, representation, or certificatio n in any record or other document submitted or required to be maintained under this permit, including monitoring reports or reports of compliance or non

- compliance shall, upon conviction, be punished by a fine of not more than $25,000 per violation, or by imprisonment for not more than two years per violation, or by both.

2 See Part V.B.1 for additional toxicity reporting requirements. MR = Moni tor and Report.

3 Valid tests must be separated by at least 13 days (from the time the first sample is taken to start one test until the time t he first sample is taken to start a different test). There is no restriction on when a new test may begin follo wing a failed or invalid test.

a. Samples used to demonstrate compliance with the discharge limitations and monitoring requirements specified above shall be taken at or near the final point

- of

- discharge but, prior to mixing with the receiving

waters or ot her waste streams.

b. If only one valid test is conducted during a quarter, results from that test must be used to assess compliance with the quarterly average limit as well as the maximum limit. If more than one valid test is completed during the quarter, the mean percent inhibition of all valid tests must be used to demonstrate compliance with the quarterly average limit.

c. Valid test results from split samples shall be reported on the DMR. For reporting an average on the DMR,

individual valid results for each test from a split sample are averaged first to determine a sample value. That value is averaged with other sample results obtained in the reporting period and the average of all sample results reported. For reporting the maximum on the DMR, individ ual valid results for each test from a split sample are averaged first to determine a sample value. That value is compared to other sample results obtained in the reporting period and the maximum of all sample results reported. For the purposes of
report ing, split samples are reported as a single sample regardless of the number of times it is split. All

laboratories used shall be identified on the DMR attachment.Part III Page 20 of 24
