The City is required to inspect certain industrial facilities on a routine basis to assess their compliance with federal and state water quality regulations as part of its NPDES stormwater permit. Below is guidance for such facilities.
Below are answers to common questions about the City's industrial stormwater inspection process.
The City has a list of the types of facilities that require inspection. This includes facilities with an NPDES permit as well as non-permitted facilities that may conduct activities with a potential to impact storm or surface waters.
City Stormwater staff will only inspect those facilities physically located in the City. If a site only has a mailing address on file with Business Licensing, staff will confirm the physical address of the location through a tax map search. Any facility located outside of City limits comes off the list of sites to be inspected even if it has a mailing address inside City limits.
City personnel may contact you prior to the inspection and ask for a copy of your Stormwater Pollution Prevention Plan (if applicable) and other site documents. City personnel may also arrive unannounced to conduct inspections.
The City is required to inspect all identified facilities at least once during its 5-year permit term (ending in 2015). The City may conduct additional inspections if necessary.
Below are answers to common questions about required self-inspection as part of the City's industrial stormwater inspection program.
Of course, you should contact S.C. DHEC first if there are any problems with your NOI paperwork. If you still need assistance, please contact City Stormwater staff to let them know about the issues. While the City cannot control how S.C. DHEC handles a facility's paperwork, City Stormwater Staff may be able to help you work through issues with the S.C. DHEC NOI process for facilities located within City limits. This assistance will depend on the current workloads of our inspectors.

Below are answers to common questions about required sampling as part of the City's industrial stormwater inspection program.
You will need to follow any sampling requirements in the permit to maintain compliance. For industrial facilities, you may be able to stop sampling for fecal coliform if you have four consecutive samples that are not above state limits. You will need to consult with S.C. DHEC and City Stormwater Staff before you stop any sampling regimen to avoid non-compliance.
You may not always be able to take a rain event sample during a quarter if there are no qualifying rain events. However, there are things you can do to show due diligence in attempting to catch those invents. You can:
Because you never know if another qualifying event will happen, you should go ahead and take that second sample even if it has been a short time since the first sample. You may want to sample again that quarter if another qualifying event occurs.
Document when you do not have a qualifying event during a quarter and/or if there are any particular hardships or hazards that prevented you from collecting during a qualifying event.
