GA EPD Issues Final NPDES Industrial Storm Water General Permit

On March 6, 2017, the Georgia Environmental Protection Division (EPD) issued the revised NPDES General Permit for Discharges Associated with Industrial Activity, GAR050000. The Permit becomes effective June 1, 2017 and expires May 31, 2022.

A few examples of modifications in the new Permit include:

  • Dumpsters and roll-offs that do not have lids and could contaminate storm water must ensure that discharges have a control (e.g., secondary containment, treatment).
  • Perform inspections and preventive maintenance of drainage structures, treatment systems, and plant equipment and systems.
  • Inspect and maintain baghouses at least quarterly and immediately remove any accumulation of dust.
  • Clean catch basins when debris depth reaches two-thirds of the basin depth. The debris surface must be at least six inches below the outlet pipe.
  • Examine erosion and sediment control measures during the Annual Comprehensive Site Inspection and state each measure as adequate or needing improvement.
  • Delineate all areas subject to erosion on the Site Map.
  • Hardness-dependent benchmark concentrations must be determined based on the receiving stream’s hardness value, and not on the site’s storm water discharge.

What’s Required: 
The Notice of Intent (NOI) must be submitted electronically to EPD on their on-line portal called “GEOS” within thirty (30) days of the Permit’s effective date of June 1st. The Storm Water Pollution Prevention Plan (SWPPP) must be updated within ninety 90 days and all changes must be implemented within 180 days of the Permit’s effective date. Additionally, any facility operating under a No Exposure Exclusion must reapply for the exclusion within 30 days of the effective date of the permit.

EPS Assistance:
If you are a current client of EPS, we will be contacting you shortly to assist in setting up your GEOS account, submitting your NOI, and preparing your new SWPPP to meet the new Permit requirements.

If you are not a current client of EPS and would like our assistance, please call Ted Peyser or Alan Anderson at (404) 315-9113.

Georgia EPD Issues the Revised Draft Industrial Storm Water General Permit

Georgia EPD has issued the Draft 2017 NPDES General Permit No. GAR050000 for Storm Water Discharges Associated with Industrial Activity. The comment period ends on September 9, 2016. EPD expects to issue a revised draft of the Permit on October 3, 2016 and hold a public hearing on November 9, 2016.

EPD has held several stakeholder meetings and received numerous comments. Some of the more significant, non-sector specific, proposed changes from the existing 2012 Permit are listed below. Note that based on stakeholder comments received, we believe that several of these proposed changes may be removed from the final Permit.

  • Catch basins/retention ponds are required to be cleaned when the depth of debris reaches 2/3 of the sump depth. The debris surface must also be at least 6 inches below the lowest outlet pipe.
  • The allowable timeframe for documentation of corrective action is reduced from 30 days to 14 days. The allowable timeframe for implementation of corrective action, without requiring approval from EPD, has been reduced from 90 days to 45 days.
  • Photo documentation of the quarterly visual (outfall) sample against a neutral background is required. A comparison of the current visual sample to past results is also required.
  • Erosion and sediment control measures must be examined more closely in the Annual Comprehensive Site Evaluation.
  • Training at hiring and annually thereafter is now required. Training topics are now specified.
  • The Site Map must include areas prone to erosion and where control measures are installed or needed.
  • The Storm Water Pollution Prevention Plan must be made available directly to the public without EPD involvement.
  • Numerous changes are proposed to Appendix C Impaired Stream Monitoring.

Currently, the effective date of the Permit is June 1, 2017. As part of the Permit renewal, companies will be required to resubmit their Notice of Intent (NOI) 30 days before the effective date of the Permit. Storm Water Pollution Prevention Plans must also be updated and in place prior to NOI submittal.
