NPDES Industrial Storm Water General Permits

Industrial General Permit

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

The Download this pdf file. 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. 

If you think your industrial site may need coverage, please see this brochure " Download this pdf file.  Does Your Industrial Site Need a Permit?  " and check for your SIC code in Appendix D of the IGP, linked above.

If you are looking for a different type of stormwater permit, here are the webpages for Construction Stormwater NPDES permits, for controlling pollutants during construction projects, and for NPDES Municipal Separate Storm Sewer Systems (MS4) Permits, for controlling pollutants from municipal stormwater discharges.

  • Renewing Coverage Under the 2022 IGP

    The 2022 NPDES General Permit No. GAR050000 for Stormwater Discharges Associated with Industrial Activity (2022 IGP) became effective June 1, 2022. This is the replacement permit for the 2017 IGP (GAR050000) which expired on May 31, 2022. The new general permit will expire on May 31, 2027.

    The 2022 forms (Notice of Intent, No Exposure Exclusion, Notice of Termination and Annual Report Forms) are available through the Georgia EPD Online System (GEOS; Older versions of these forms will not be accepted nor will submissions sent on paper in the mail. If you have questions regarding GEOS, please review this help document:   Industrial Stormwater GEOS Guide.

  • Submitting Annual Reports

    Permittees who are covered via an NOI under the Industrial General Permit (IGP) must submit an Annual Report (AR) for their facility for each calendar year by January 31st of the following year. All submittals must be made through the Georgia EPD Online System (GEOS; Only Responsible Officials (ROs) and the Preparers they assign can complete the AR.

    Annual Reports no longer contain quantitative sample data as in years past; Annual Reports should contain qualitative data about the site (for example, information about corrective actions and BMP updates). Quantitative sample data (the results from samples sent to a lab, for example) go into NetDMR only. For more information about NetDMR, please see the section below called "NetDMR Reminders and Resources."

    REMINDER: 2023 Annual Report Reminder

    This is a reminder that Annual Reports (AR) for the period covering January 1, 2023 to December 31, 2023 are due by January 31, 2024 for those facilities that filed a Notice of Intent (NOI) under the 2022 Industrial General Permit (IGP). The AR form must be submitted electronically through the Georgia EPD Online System (GEOS). Please refer to the Download this pdf file.

    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.  

    2. GAR050000 is the general permit number.  Your specific permit number for use in NetDMR is found in GEOS Download this pdf file. (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


    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 



    Other notables:

    •            Annual Reports get reported in GEOS (please see the section above this called "Submitting Annual Reports.")

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

  • Tools to Determine Impaired Waters from Current 305(b)/303(d) List

    The IGP requires permitted facilities to determine if they discharge into, or within one linear mile, upstream of, and in the same watershed as, any portion of an impaired water. Impaired Waters are those waterbodies where the EVALUATION is listed as NOT SUPPORTING on Georgia’s 305(b)/303(d) List of Waters. This information is autopopulated on the NOI/NEE form on GEOS, but permittee should check using the tools below.


    Full lists of all impaired waterbodies, as well as listing methodology and key abbreviations, are available at Please use the 2022 List Documents and Integrated Report, since these are the most recent approved lists.


    The GIS datasets are available at:

    EPD's Industrial Facility Inspection Form

    EPD conducts between 100 to 125 inspections per year of facilities either permitted under the IGP through submission of a Notice of Intent or excluded from coverage through submittal of a No Exposure Exclusion.  Below is the form we use to inspect.  Please note that it generally follows the order of the permit and that permit citations are given for most items.

    MS4 Contact List

    Facilities covered under the IGP that discharge to a Municipal Separate Storm Sewer System (MS4) are required to send a copy of their Notice of Intent (NOI) to the MS4.  Please refer to the MS4 Stormwater Contact List below to determine the county where your facility is located.

    Permittee Lists for NPDES Industrial Stormwater 2022 IGP

    This is a list of the facilities that either have coverage under 2022 IGP Notice of Intent (NOI) or exemption from No Exposure Exclusion (NEE). Whether they have an NOI or NEE is indicated in the column entitled “Submittal Type.”

    SIC Code Reference Materials

    If your facility has a primary Standard Industrial Classification (SIC) code listed in Appendix D of the IGP and discharges stormwater associated with industrial activity, then the facility must file a Notice of Intent (NOI) for coverage under the IGP or a No Exposure Exclusion (NEE) for exemption from it.
