Industrial Stormwater General Permit (IGP)

Georgia's Industrial Stormwater General Permit, which the Georgia Environmental Protection Division (EPD) calls the Industrial General Permit (IGP), is the state's general National Pollutant Discharge Elimination System (NPDES) permit regulating stormwater runoff from industrial sites. The 2022 IGP, General Permit No. GAR050000, became effective June 1, 2022 and will expire on May 31, 2027. It replaced the 2017 IGP, which expired on May 31, 2022. EPD posts a list of the facilities covered by the 2022 IGP or excluded from it.

In a Phase I ESA

ASTM E1527-21 does not name stormwater permit lists among its standard record sources. The IGP list is still a list of industrial facilities that have coverage under the permit or an exemption from it.

• The industry code decides. EPD says that if a facility's primary Standard Industrial Classification (SIC) code is listed in Appendix D of the IGP and the facility discharges stormwater associated with industrial activity, it must file a Notice of Intent (NOI) for coverage or a No Exposure Exclusion (NEE) for exemption.
• Two kinds of entry. EPD describes an NOI as for facilities conducting industrial activities with the potential to come in contact with stormwater, and an NEE as a facility's certification that no industrial activities are exposed to stormwater. The list shows which in its Submittal Type column. An NEE is the facility's own certification, so read it with the site visit.
• Older annual reports hold sample data. EPD says a facility covered by an NOI must submit an Annual Report through GEOS, the Georgia EPD Online System, for each calendar year by January 31 of the next year; a facility that filed an NEE does not. EPD says annual reports no longer contain quantitative sample data as they did in years past, and that sample results now go into the U.S. Environmental Protection Agency's NetDMR only, quarterly from January 1, 2023. For a facility's sampling history, ask for the older annual reports as well as the discharge monitoring reports.
• The local storm sewer system may hold a copy. EPD says facilities covered under the IGP that discharge to a municipal separate storm sewer system (MS4) are required to send a copy of their NOI to the MS4. Ask the MS4 for its copy as well.

EPD says it conducts between 100 and 125 inspections a year of facilities with an NOI or an NEE, and it posts the checklist it uses.

What the record shows

EPD describes its List of Facilities Covered Under the 2022 IGP as the facilities that either have coverage under a 2022 IGP NOI or an exemption by NEE. The copy posted when read was dated September 2026. The page read does not describe the list's other columns, and it does not link lists for earlier permits. A facility covered only under an earlier permit falls outside that description.

EPD says the 2022 forms, among them the NOI, the NEE, the Notice of Termination and the annual report, are available through GEOS, and that older versions of the forms and submissions sent on paper in the mail are not accepted. In NetDMR, a facility's permit number is not GAR050000, the general permit number every covered industry shares. EPD says it is GAIS followed by the last five digits of the facility's NOI unique ID number.

Where to look a site up

• The list, the permit, its Appendix D and the inspection checklist are on EPD's NPDES Industrial Storm Water General Permits page.
• Filings are made in GEOS; EPD lists Storm Water Industrial among its GEOS programs. The pages read do not say whether these filings can be viewed in the Public Inquiry Portal.
• EPD's Stormwater page gives 404-463-1511. The Industrial Storm Water Unit's mailbox is on the permit page.

Getting the file

These are Watershed Protection Branch records, not Land Protection Branch records. EPD's Watershed Protection Branch page says a Georgia Open Records Act request to the branch goes through its Open Records Request Portal. Give the facility's name and address, and ask for the NOI or NEE, the annual reports and any notice of termination.
