NPDES Industrial Storm Water General Permits

FAQs regarding quarterly data reporting in NetDMR 

What is due, when? 

  1. Quarterly discharge monitoring reports (DMRs) are required to be submitted through NetDMR 45 days following the quarterly reporting period starting January 1, 2023.  That means that the first quarterly reporting is due May 15, 2023. 

What if I haven’t collected any data yet? 

  1. Quarterly reporting is still required in NetDMR.  You must still log into NetDMR and enter NODI code 9 to indicate “Conditional Monitoring – Not Required”. 

What is my Permit Number in the DMR system? 

  1. Your permit number will be “GAIS” + the last 5 digits of your NOI unique ID number. Your NOI number can be found inside your ARs or inside of GEOS after the word “watershed” in the source column of the permits under your account.  Your permit number will not be GAR050000 in this system…that is the general permit number shared by every industry covered by this permit.  

If there are errors in the parameters of the DMR... 

  1. For extra parameters you should not have: please use NODI code 9 and include a comment in the comment box inside of the DMR to highlight what parameters were added in error. 
  2. For parameters that were left out/omitted: provide data inside the comment box for parameters that may have been omitted.  
  3. If you have something called MSP as an outfall: MSP means “material storage pile”. If we gave you that in error, please use NODI code 9 and the comment box inside of the DMR to say that you do not have a material storage pile. 

Note: the use of NODI code 9 satisfies the reporting requirement and will prevent the auto-generation of a violation 

2022 Annual Report & Monitoring Reminder

Annual Reports (AR) and 2022 monitoring data for the period covering January 1, 2022 to December 31, 2022 are due by January 31, 2023 for those facilities that filed a Notice of Intent (NOI). The AR form and data must be submitted electronically through the Georgia EPD Online System (GEOS). A guide for submitting your annual report and tips for a successful submittal can be found below.  This process remains unchanged from previous years.

NetDMR Reminders and Resources

GAR050000 is the general permit number.  Your specific permit number for use in NetDMR is found in GEOS (PDF) 

The permit number in NetDMR will consist of 9 characters starting with "GAIS00000"  (example: GAIS12345, GAIS01234).  If your number, as found in GEOS, is already 9 numbers with 4 leading zeros, simply replace those leading zeros with the characters “GAIS” so that the NetDMR permit number totals 9 alphanumeric characters.

Reasons permit may not be in NetDMR:

•            Unapproved NOI's will not be in NetDMR. 

•            NEE's do not report in NetDMR

Other notables:

•            Annual Reports get reported in GEOS

•            ALL 2022 annual reports & sampling data should be reported in GEOS only.

•            NetDMR is for reporting sampling data collected beginning as of January 1, 2023. NetDMR is not for data collected during calendar year 2022.


The Georgia Environmental Protection Division (EPD) Watershed Protection Branch has initiated bi-annual stakeholder workgroup meetings to review and discuss PERMIT NO. GAR050000, hereafter called the IGP. These meetings provide stakeholders with the opportunity to engage in dialog with EPD staff to discuss the implementation of the 2022 IGP throughout the term of the permit.

The first virtual meeting was held on November 18, 2022 and focused on proposed corrections, such as typos and omissions, to the 2022 IGP.  Slides from this meeting are available here .

The second Industrial Stormwater Stakeholder Workgroup Meeting was held on October 25, 2023. View the meeting agenda here  and  view the slides from this meeting here

GEOS Submittal Guidance for Industrial Stormwater General Permit

Georgia EPD reissued the Industrial Stormwater General Permit (GAR050000) on May 20, 2022 and became effective June 1, 2022.  The permit contains a renewal submission deadline of 30 days after the effective date of the permit.  It has come to our attention that facilities are experiencing difficulties successfully submitting their renewals in GEOS.  We are actively working with our contractors to resolve the issues.  If you have attempted a timely submittal but are unable to renew by the permit specified date, please do the following:

•            Document and retain your submittal attempts using screen shots of error messages, etc. to show substantial compliance with the permit requirement

•            Once the NOI/NEE form is available to you, please enter the date of your first attempted submittal under Part E. Certification

EPD will ensure that the effective date of permit coverage aligns with the date provided on the NOI/NEE form.

Industrial General Permit

The 2022 Industrial Stormwater General Permit forms (Notice of Intent and No Exposure Exclusion) are now available in GEOS.

The 2022 Industrial General Permit (IGP) is the State's general NPDES (National Pollutant Discharge Elimination System) Permit regulating stormwater runoff from industrial sites. The creation of this Permit allowed many industries to be uniformly covered, with specific requirements varying by industrial sector. Implementing preventative measures on site rather than trying to mitigate the pollutants once in the environment is the most effective and economic way to protect water quality. 

EPD offers two types of coverage under the Permit. 

Permit Type Description
Notice of Intent (NOI) Facilities conducting industrial activities with the potential to come in contact with stormwater.  
No Exposure Exclusion (NEE) Facilities certify that no industrial activities are exposed to stormwater.
