Illicit Discharge Detection and Elimination Policy
This section has been reviewed and updated as needed: June 2014
- To improve the quality of surface water and ground water within the watershed areas owned and maintained by the University of North Carolina at Chapel Hill (UNC-Chapel Hill) by preventing illicit discharges and illicit connections.
- To prevent the discharge of contaminated stormwater runoff from UNC-Chapel Hill properties and operations into the storm drainage system and natural waters within UNC-Chapel Hill.
- To comply with the requirements of UNC-Chapel Hill’s stormwater permit.
- To comply with all United States Environmental Protection Agency and State laws applicable to stormwater discharges.
An Illicit Connection is the discharge of pollutants or non-stormwater materials into the storm drainage system via a pipe or other direct connection. Sources of illicit connections may include sanitary sewer taps, wash water from laundry facilities, wash water from sinks, or other similar sources.
Any drain or conveyance, whether on the surface or subsurface, which allows any nonstormwater discharge, including but not limited to sewage, process water, waste water, or wash water, to enter the stormwater drainage system, and any connections to the storm drain system from indoor drains or sinks.
- Discharges that are specifically permitted under a State or federal stormwater program
- Incidental non-stormwater discharges which do not significantly contribute to the pollution of UNC-Chapel Hill surface waters and are limited to the following:
- water line flushing
- reclaimed water line flushing
- landscape irrigation, including but not limited to reclaimed water
- diverted stream flows
- rising groundwater
- uncontaminated groundwater infiltration
- uncontaminated pumped groundwater
- discharges from potable water sources
- foundation drains
- air conditioning condensate (that does not contain biocide)
- water from crawl space pumps
- footing drains
- flows from riparian buffers and wetlands
- dechlorinated swimming pool discharges
- flows from emergency fire fighting
- building wash water without detergents, cleaners, or corrosive additives
- In the event that UNC-Chapel Hill determines that any of the above discharges contribute to pollution of campus streams or other surface waters or is notified by a State or federal government agency, such as the North Carolina Division of Water Quality, that the discharge must cease, UNC-Chapel Hill will instruct the responsible person to cease the discharge.
- When instructed to cease the discharge, the discharger of substances newly classified as pollutants shall cease the discharge immediately and be given reasonable time to make corrections so that the discharge will not continue into the future.
- Nothing in this Policy shall affect a discharger’s responsibilities under federal or State law.
- Whenever UNC-Chapel Hill finds that a violation of this Policy has occurred, UNC-Chapel Hill may order compliance by written notice to the responsible person. Such notice may require without limitation:
- The performance of monitoring, analyses, and reporting
- The elimination of prohibited discharges or connections
- Cessation of any violating discharges, practices, or operations
- The abatement or remediation of stormwater pollution or contamination hazards and the restoration of any affected property
- Payment of any fee, penalty, or fine assessed against UNC-Chapel Hill to cover remediation cost
- The implementation of new stormwater management practices
- Disciplinary action up to and including dismissal, where appropriate
- Such notification shall set forth the nature of the violation(s) and establish a time limit for correction of these violation(s). Said notice may further advise that, if applicable, should the violator fail to take the required action within the established deadline, then UNC-Chapel Hill’s Department of Environment, Health and Safety will initiate work orders for the appropriate corrective actions and the individual or University department will be charged for the cost.
This Policy is effective 3/5/2009. Last revised 3/5/2009.
This Policy is maintained and enforced by the Department of Environment, Health and Safety.
