Permittees under the Georgia Industrial Storm Water General Permit must document, on the annual report, that they have evaluated for the presence of non-storm water discharges annually and that all unauthorized discharges have been eliminated.If there are any floor drains in the production area and/or sinks that are not in the bathroom, kitchen, breakroom, etc., evaluation is required.
The evaluation includes:
• Locating potential connections to your storm water system.
• Verification that floor drains and connections go to municipal sewer.
The above needs to be verified from asbuilt drawings and/or by conducting a
smoke and dye test at least once during the term of the permit. The smoke and dye
test must be conducted to evaluate for the presence of non-storm water discharges
into the storm sewer system from all floor drains, and from all sinks in industrial
areas excluding eyewash stations that were installed prior to 1/1/2006.
Facilities must document, in the annual report, the date of the last smoke, dye
or equivalent test, or why this test is not applicable to the facility.
Examples of acceptable equivalent tests include television surveillance, and analysis of as-built drawings and piping and drainage schematics. Facilities that certify on their annual report that they have made an analysis within the last 5 years of as-built drawings and/or piping and drainage schematics and found them current and accurate have met this requirement.
