Industrial Stormwater Permitting

CTI offers assistance to facilities with all multiple facets of National Pollutant Discharge Elimination System (NPDES) stormwater permitting services in a cost-effective and timely manner. Our services in this area include assisting with industrial stormwater permitting and design which include preparing Stormwater Pollution Prevention Plans (SWP3) and Best Management Practices (BMPs) Plans.

CTI’s services extend beyond the initial preparation of the SWP3; in order to decrease the burden on a facility’s time and energy, we can perform required storwmater inspections, assist with and manage stormwater sampling procedures, respond to Notice of Violations (NOVs), prepare Notices of Intent (NOIs), prepare Annual Reports, conduct annual Storm Water Training and much more.

Smoke & Dye Testing (Georgia)

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., further evaluation is required. CTI can conduct onsite smoke and dye testing to satisfy this requirement.

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 as-built 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.
