DIVISION 9. SPECIAL POLLUTION ABATEMENT PERMITS
(a) A Special Pollution Abatement Permit is required when development or re-development occurs within a watershed that drains to a waterbody listed as impaired by the South Carolina Department of Health and Environmental Control or has an established total maximum daily load (TMDL) developed and implemented for a pollutant(s) of concern to ensure that effective best management practices are used to control water quality for these waterbodies. A Special Pollution Abatement Permit will be valid for a period of 5 years, at which point it must be renewed. At the time of renewal, any deficiencies in the control of the targeted pollutants or management method must be corrected. Any development that occurs without a required permit shall be a violation of this chapter of the code.
(b) Development in other areas known to have particular adverse water quality pollutant impacts may be required to comply with this section at the discretion of the Director. Areas that qualify have been identified by sampling and monitoring results and are given as priority areas for water quality treatment. Outstanding resource waters may also qualify for compliance under this section for protection of their classification.
(Ord. 4281, passed 5-5-2009; Ord. 4698, passed 5-5-2015)
All special pollution abatement permit requests shall include as a minimum the following information:
(a) Name of the development.
(b) Physical location of the development.
(c) Name of impaired waterbody that receives stormwater discharge from the development.
(d) Pollutant(s) of concern that is responsible for the designated impairment.
(e) Supporting information for the permit request, including:
(1) Name of contact person for permit compliance.
(2) Site map (minimum scale of 1” =-50’) of development with buildings, parking, drives, other impervious surfaces, ditches, pipes, catch basins, drainage basin limits, acreage of offsite water draining onto the development, discharge points to Waters of the United States or Waters of the State, and locations of stormwater treatment facilities and BMPs.
(3) Stormwater treatment facilities and BMPs including manufacturer, model, flow rates of runoff draining to each facility or BMP for the 1-year and 10-year 24-hour storms, and the verified treatment and bypass flows for each facility and BMP.
(4) Inspection and maintenance program and schedule for each facility or BMP.
(f) Certification by the engineer of record that the stormwater treatment facility or BMP will address the pollutants listed in the TMDL or on the impairment for the waterbody on the 303(d) and meets the requirements in the TMDL for the subject waterbody.
(g) Certification by the operator that the facility or BMP will be maintained and inspected according to the inspection and maintenance program detailed in the permit request. Certified quarterly reports shall be submitted to the Director by the operator of the facility or as the Director requires as given in the permit conditions. Sampling and monitoring may be required to verify the performance of the facility and compliance with the requirements in the Special Pollution Abatement Permit.
(Ord. 4281, passed 5-5-2009; Ord. 4698, passed 5-5-2015)
Before the approval of structural stormwater treatment devices, the Director may require valid documentation from full-scale testing by an independent third party to verify that the pollutants of concern will be properly controlled if they are not on the approved list.
(Ord. 4281, passed 5-5-2009; Ord. 4698, passed 5-5-2015)
