(A) Wastewater analysis. When requested by the control authority, a user must submit information on the nature and characteristics of its wastewater within 30 days of the request. The control authority is authorized to prepare a form for this purpose and may periodically require users to update this information.
(B) Permit required. All industrial users proposing to connect or discharge to the POTW shall obtain a wastewater discharge permit before connecting to or contributing to the POTW.
(1) No significant industrial user shall discharge wastewater into the POTW without first obtaining an individual wastewater discharge permit or a general permit from the control authority, except that a significant industrial user that has filed a timely application pursuant to division (C) below may continue to discharge for the time period specified therein.
(2) The control authority may require other users to obtain individual wastewater discharge permits or general permits as necessary to carry out the purposes of this chapter.
(3) Any violation of the terms and conditions of an individual wastewater discharge permit or a general permit shall be deemed a violation of this chapter and subjects the wastewater discharge permittee to the sanctions set out in §§ 56.63 through 56.70 and § 56.99. Obtaining an individual wastewater discharge permit or a general permit does not relieve a permittee of its obligation to comply with all federal and state pretreatment standards or requirements or with any other requirements of federal, state, and local law.
(C) Individual wastewater discharge and general permitting: existing connections. Any user required to obtain an individual wastewater discharge permit or a general permit who was discharging wastewater into the POTW prior to the effective date of this chapter and who wishes to continue such discharges in the future, shall, within 30 days after said date, apply to the control authority for an individual wastewater discharge permit or a general permit in accordance with division (E) below.
(D) Individual wastewater discharge and general permitting: new connections. Any user required to obtain an individual wastewater discharge permit or a general permit who proposes to begin or recommence discharging into the POTW must obtain such permit prior to the beginning or recommencing of such discharge. An application for this individual wastewater discharge permit or general permit, in accordance with division (E) below, must be filed at least 90 days prior to the date upon which any discharge will begin or recommence.
(E) Individual wastewater discharge and general permit application contents.
(1) All users required to obtain an individual wastewater discharge permit or a general permit must submit a permit application. Users that are eligible may request a general permit under division (F) below. The control authority may require users to submit all or some of the following information as part of a permit application:
(a) Identifying information.
1. The name and address of the facility, including the name of the operator and owner;
2. Contact information, description of activities, facilities, and plant production processes on the premises.
(b) Environmental permits. A list of any environmental control permits held by or for the facility.
(c) Description of operations.
1. A brief description of the nature, average rate of production (including each product produced by type, amount, processes, and rate of production), and standard industrial classifications of the operations) carried out by such user. This description should include a schematic process diagram, which indicates points of discharge to the POTW from the regulated processes;
2. Types of wastes generated, and a list of all raw materials and chemicals used or stored at the facility which are, or could accidentally or intentionally be, discharged to the POTW;
3. Number and type of employees, hours of operation, and proposed or actual hours of operation;
4. Type and amount of raw materials processed (average and maximum per day);
5. Site plans, floor plans, mechanical and plumbing plans, and details to show all sewers, floor drains, and appurtenances by size, location, and elevation, and all points of discharge;
(d) Time and duration of discharges;
(e) The location for monitoring all wastes covered by the permit;
(f) Flow measurement. Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams, as necessary, to allow use of the combined wastestream formula set out in § 56.20(A)(3) [SC R.61-9.403.6(f)].
(g) Measurement of pollutants.
1. The categorical pretreatment standards applicable to each regulated process and any new categorically regulated processes for existing sources.
2. The results of sampling and analysis identifying the nature and concentration, and/or mass, where required by the standard or by the control authority, of regulated pollutants in the discharge from each regulated process.
3. Instantaneous, daily maximum, and long-term average concentrations, or mass, where required, shall be reported.
4. The sample shall be representative of daily operations and shall be analyzed in accordance with procedures set out in § 56.15. Where the standard requires compliance with a BMP or
pollution prevention alternative, the user shall submit documentation as required by the control authority or the applicable standards to determine compliance with the standard.
5. Sampling must be performed in accordance with procedures set out in § 56.16(B).
(h) Any requests for a monitoring waiver (or a renewal of an approved monitoring waiver) for a pollutant neither present nor expected to be present in the discharge based on § 56.42(D)(2) [SC R.61-9.403.12(e)(2)].
(i) Any request to be covered by a general permit based on division (F) below.
(j) Any other information as may be deemed necessary by the control authority to evaluate the permit application.
(2) Incomplete or inaccurate applications will not be processed and will be returned to the user for revision.
(F) Wastewater discharge permitting: general permits.
(1) At the discretion of the control authority, the control authority may use general permits to control SIU discharges to the POTW if the following conditions are met. All facilities to be covered by a general permit must:
(a) Involve the same or substantially similar types of operations;
(b) Discharge the same types of wastes;
(c) Require the same effluent limitations;
(d) Require the same or similar monitoring; and
(e) In the opinion of the control authority are more appropriately controlled under a general permit than under individual wastewater discharge permits.
(2) To be covered by the general permit, the SIU must file a written request for coverage that identifies its contact information, production processes, the types of wastes generated, the location for monitoring all wastes covered by the general permit, any requests in accordance with § 56.42(D)(2) for a monitoring waiver for a pollutant neither present nor expected to be present in the discharge, and any other information the POTW deems appropriate. A monitoring waiver for a pollutant neither present nor expected to be present in the discharge is not effective in the general permit until after the control authority has provided written notice to the SIU that such a waiver request has been granted in accordance with § 56.42(D)(2).
(3) The control authority will retain a copy of the general permit, documentation to support the POTW's determination that a specific SIU meets the criteria in divisions (F)(l)(a) through (e) and applicable state regulations, and a copy of the user's written request for coverage for three years after the expiration of the general permit.
(4) The control authority may not control an SIU through a general permit where the facility is subject to production-based categorical pretreatment standards or categorical pretreatment standards expressed as mass of pollutant discharged per day or for IUs whose limits are based on the combined wastestream formula (§ 56.20(A)(3)) or net/gross calculations (§ 56.20(A)(4)).
(G) Application signatories and certifications.
(1) All wastewater discharge permit applications, user reports and certification statements must be signed by an authorized representative of the user and contain the certification statement in § 56.42(I).
(2) If the designation of an authorized representative is no longer accurate because a different individual or position has responsibility for the overall operation of the facility or overall responsibility for environmental matters for the company, a new written authorization satisfying the requirements of this section must be submitted to the control authority prior to or together with any reports to be signed by an authorized representative.
(H) Permit decisions. The control authority will evaluate the data furnished by the user and may require additional information. Upon determination by the control authority that a wastewater discharge permit will be issued, the limits will be developed and submitted to SCDHEC and shall only be instituted at such time as SCDHEC approval is received. The control authority may deny any application for a wastewater discharge permit.
