The Ohio EPA NPDES Industrial Stormwater Permit is a general permit (current version OHR000007, effective June 1, 2022) that lets industrial facilities legally discharge rainwater runoff into Ohio’s streams, rivers, and storm sewers, and you apply for it by filing a one-page Notice of Intent (NOI) through the Ohio EPA eBusiness Center. Any factory, scrap yard, recycler, or trucking terminal whose outdoor operations touch rain or snowmelt must file this NOI before discharging, or face penalties under Ohio Revised Code Chapter 6111.
Skipping this permit is not a small oversight. Stormwater that runs across a metal shop’s yard or a salvage lot can carry oil, metals, and grit straight into a creek, and Ohio’s Division of Surface Water treats an unpermitted discharge as an illegal one. With thousands of facilities covered statewide under a single $350 application, the program is built for volume, which means the agency returns incomplete or unpaid NOIs without mercy and the clock on your discharge keeps ticking.

What the Permit Is and Who Must File It
The Ohio EPA industrial stormwater general permit, known as the Multi-Sector General Permit (MSGP), is a single statewide NPDES permit that authorizes rainwater runoff from industrial sites to reach surface waters. The current version, OHR000007, took effect June 1, 2022 and replaced the prior OHR000006. It exists because the federal Clean Water Act of 1972 makes it unlawful to discharge pollutants from a point source without an NPDES permit, and Ohio, as a delegated state, runs the program through its Division of Surface Water.
You must file if your facility falls into one of the eleven categories of industrial activity in 40 CFR 122.26 and Ohio Administrative Code 3745-39-04. These include primary metals, fabricated metal products, scrap and auto salvage yards, transportation terminals, food processing, chemicals, and dozens more sectors. The simple test is exposure: if industrial materials, machinery, or waste sit outdoors where rain can touch them and then run off your land, you need coverage.
The agency that receives the form is Ohio EPA’s Division of Surface Water, the statute that requires it is ORC Chapter 6111, and the penalty for ignoring it is enforcement for an unpermitted discharge. A common misconception is that a business license or a building permit covers stormwater. It does not. Stormwater authorization is separate, and only the NOI (or an individual permit) grants it.
The Plain-English Version of the Law
The Clean Water Act bans dumping pollutants into “waters of the United States” without a permit. The consequence of ignoring this is steep: federal and state law allow civil penalties that can reach thousands of dollars per day of violation. Picture a small foundry that lets runoff drain to a creek for two years with no permit; when Ohio EPA finds it, the back-dated exposure becomes the basis for an enforcement order. The misconception here is that stormwater is “just rain,” but once it crosses an industrial yard, the law treats it as a regulated discharge.
Before You Start: Documents and Information You Need
Filing goes fast once you have your facts in hand, and it stalls when you don’t. Gather these items before you open the form, because the eBusiness Center will not save partial data the way a paper draft would, and a missing piece can force you to start over.
- Legal company name — the entity that controls the facility; a wrong name puts the permit in the wrong hands.
- Facility physical address and county — no P.O. boxes allowed; the agency maps your site from this.
- Latitude and longitude in decimal format to six places — pulled from the center of your site; bad coordinates misplace your discharge.
- Primary 4-digit SIC code — describes your main activity; the wrong code sends you to the wrong monitoring sector.
- Receiving water name or MS4 operator — where runoff ends up; leaving this blank stalls review.
- Outfall locations and counts — each pipe, ditch, or channel leaving your site; missing outfalls undercount your monitoring duties.
- Existing NPDES permit number (if renewing) — found on your prior approval letter; omitting it can create a duplicate record.
- OH|ID account and eBusiness PIN — required to sign and submit electronically; without these you cannot file at all.
- A completed or in-progress SWPPP — your Stormwater Pollution Prevention Plan must exist before you file, because you certify you will implement it.
- $350 payment — by ePayment or check to “Treasurer, State of Ohio”; an NOI without payment is returned.
Each item matters because Ohio EPA cross-checks the data against its records and your SWPPP. If your SWPPP is missing, you are certifying to a plan that does not exist, which is a false certification. If your SIC code is wrong, you may skip benchmark monitoring you actually owe, and that surfaces later as a violation.
Where to Get the Form and How to Access It
The NOI is not a PDF you print and mail by default. It is an electronic application form inside the Ohio EPA eBusiness Center, and electronic filing is the required channel under OHR000007. You reach it by creating an OH|ID account, logging into the eBusiness Center, and opening the Surface Water (DSW) eForms service area where the Industrial Storm Water NOI lives.
To submit, you also need a Personal Identification Number (PIN). The PIN is your legal electronic signature, so the agency issues it only after you complete a one-time identity verification. Existing eBusiness Center account holders use their existing PIN; new users should request the PIN early, because it can take days to arrive and you cannot finalize the NOI without it.
If you genuinely cannot use the online system, the permit allows a hardship paper filing. You request a paper NOI from Ohio EPA and mail it with a check to: Ohio Environmental Protection Agency, Office of Fiscal Administration, P.O. Box 1049, Columbus, OH 43216-1049. The misconception to avoid is that paper is a free choice; it is not. You must demonstrate a hardship, and faxed NOIs are never accepted.
Step-by-Step: How to Fill Out the Industrial Stormwater NOI Line by Line
The NOI is organized into four sections plus a certification block. Work through them in order, because later sections depend on choices you make earlier, such as your SIC code driving your outfall and monitoring entries. Use the exact field labels printed on the form, and remember the agency’s formatting rule: type or print legibly, one space between words, and no stray symbols or punctuation unless an instruction calls for it.
Section I — Company Name
This field asks for the legal name of the business that runs the site, not the building’s nickname. Enter the full legal name of the firm, person, public agency, or other entity that operates the facility and controls its operations. For example, MERIDIAN METAL WORKS LLC writes its registered LLC name, not “the Lorain plant.” A nuance: the operator’s name may differ from the facility name, so use the responsible legal entity here even if locals call the site something else. The common mistake is entering a plant manager’s name or a trade name, which puts the permit under the wrong party and can void responsibility. People often believe the company name and facility name must match, but they frequently do not.
Section I — Mailing Address
This field asks where Ohio EPA should mail your permit and all correspondence. Enter the complete mailing address with street, city, state, and ZIP code. For example, 475 INDUSTRIAL PKWY, LORAIN, OH 44052. Here a P.O. Box is allowed, because this is for mail, not for locating the site. The common mistake is using an address nobody checks, so the approval letter and renewal notices vanish; missing a re-notify notice can drop your coverage. Many filers wrongly assume this address must be the facility itself, but a corporate office address is fine for mailing.
Section I — Contact Person, Phone, Fax, and E-Mail
This field asks who at the company answers NPDES questions. Enter the name, phone, fax, and email of the person responsible for permit matters. For example, Contact: PRIYA NATARAJAN, Phone: 440-555-0148, Email: priya@meridianmetal.com. A nuance: pick someone who will still be reachable in a year, because Ohio EPA contacts this person about monitoring and renewals. The common mistake is listing a consultant who later moves on, leaving no live contact and delayed responses to agency letters. People wrongly think this must be an owner; it can be any responsible staff member.
Section II — Facility Name
This field asks for the official or legal name of the site where the discharge happens. Enter the facility’s real name, not a colloquial one. For example, MERIDIAN METAL WORKS – LORAIN FACILITY. The nuance is that one company may run several facilities, and each site needs its own NOI and its own name. The common mistake is reusing the corporate name when the site has a distinct identity, which muddles the agency’s site records. Filers often believe one NOI can cover multiple locations, but coverage is site-specific.
Section II — Facility Address/Location and County
This field asks for the physical location of the operation and discharge. Enter the number, street, city or township, state, ZIP, and county, and do not use a P.O. Box. For example, 475 INDUSTRIAL PKWY, LORAIN, LORAIN COUNTY, OH 44052. The nuance: county matters because Ohio EPA assigns district inspectors by county, so naming the right one routes your file correctly. The common mistake is entering a mailing P.O. Box, which the agency rejects because it cannot inspect a post office box. People wrongly assume the mailing and physical address are interchangeable; for this field they are not.
Section II — Latitude and Longitude
This field asks for the geographic coordinates of your site’s center. Provide latitude and longitude in decimal format to six decimal places, taken from the approximate middle of the facility, such as Latitude: 41.452100, Longitude: -82.182300. You can find these with a GPS unit or by right-clicking the center of your site in Google Maps. The nuance: take the reading from the center of the property, not the front gate, so the mapped point reflects the whole site. The common mistake is swapping the sign on longitude or using too few decimals, which drops your facility into the wrong watershed on Ohio EPA’s maps. Filers often think an approximate address is enough, but the program relies on exact coordinates.
Section II — Receiving Stream or MS4
This field asks where your stormwater actually goes. If you discharge directly to a water body, enter its name; if it has no name, write unnamed tributary to followed by the first named water downstream. For example, Black River or unnamed tributary to Black River. If you instead discharge into a municipal storm sewer, enter the MS4 operator’s name, such as CITY OF LORAIN. The nuance: if runoff splits to more than one stream, list every receiving water and attach a sheet if needed. The common mistake is leaving this blank or guessing, which stalls review because the agency must know the receiving water to judge water-quality impact. Many filers wrongly assume a roadside ditch is unregulated, but a ditch that carries water to a stream still counts.
Section III — General Permit Number
This field identifies which general permit you want. The number for the current industrial stormwater general permit is OHR000007, and it is pre-filled on the electronic form. You confirm it rather than type it. The nuance: if you accidentally land on a construction or marina permit form, the number will read differently, signaling you are in the wrong eForm. The common mistake is filing under an outdated number like OHR000006, which no longer grants coverage. Filers sometimes believe any stormwater permit will do, but industrial activity needs this specific MSGP.
Section III — Initial or Renewal Coverage
This field asks whether you are starting fresh or continuing existing coverage. Place an X in the box for Initial if this is your first time, or Renewal if you are continuing under the renewed permit. For example, a brand-new recycler marks Initial. The nuance: renewals must happen within 90 days of Ohio EPA’s written re-notify instructions, while new facilities file 180 days before discharge begins. The common mistake is marking initial when you are really renewing, which can create a duplicate file and lose your monitoring history. People wrongly think renewal is automatic, but you must affirmatively re-notify each permit cycle.
Section III — Existing NPDES Permit Number
This field asks for any NPDES permit your facility has held before. If you ever had an individual permit or general permit coverage, enter that number, such as an individual permit 3IA00555AD or a prior general permit ID 0GR00999DG. The nuance: on a renewal it is critical to enter the facility-specific general permit ID from your last approval letter, not the master OHR number. The common mistake is leaving this blank on a renewal, which severs the link to your existing record and can reset your monitoring clock. Filers often confuse the statewide permit number with their site-specific coverage ID, but only the site ID belongs here.
Section III — Primary SIC Code
This field asks for the four-digit code that best describes your main product or service. Enter your primary SIC code, which you can look up on the OSHA SIC search tool. For example, a fabricated-metal shop enters 3469, and a scrap recycler enters 5093. For narrative-described activities, use the two-letter codes instead, such as HZ for hazardous waste facilities or SE for steam electric generating sites. The nuance: your SIC code drives your sector and subsector, which sets your benchmark monitoring duties. The common mistake is picking a code for a minor sideline activity, which routes you to the wrong monitoring rules and creates compliance gaps. Many filers think SIC codes are obsolete because NAICS exists, but Ohio EPA still classifies stormwater sectors by SIC.
Section III — Outfall Information
This grouping asks you to describe each point where stormwater leaves your site, and you complete it only if you are subject to benchmark or effluent monitoring. For each outfall, enter a number (001, 002), the SIC code for the area draining to it, the subsector from the permit’s sector list, any applicable effluent limitation from the drop-down (or Not Applicable), and the outfall’s latitude and longitude. For example, Outfall 001, SIC 5093, Subsector N1, Effluent Limit: Not Applicable, Lat 41 27 07, Long -82 10 58. Note that outfall coordinates use degrees-minutes-seconds with two digits each and no symbols, unlike the decimal facility coordinates. The nuance: if you have six or more outfalls, list the extras on an attached sheet. The common mistake is undercounting outfalls or skipping the subsector, which understates your sampling obligations and surfaces later as missed benchmark monitoring. Filers often assume one outfall covers a whole yard, but every separate pipe or channel is its own outfall.
Section IV — Payment Information
This field records how you pay the $350 fee. Pay directly through the ePayment system in the eBusiness Center, or, if filing on paper, enclose a $350.00 check payable to Treasurer, State of Ohio and write the check number and check date on the NOI. Enter dates as month-day-year with two digits each, such as 09 28 26, and use no symbols. The fee authority is paragraph (S)(1) of ORC Section 3745.11. The nuance: ePayment is faster and avoids a lost-check problem, so most online filers should choose it. The common mistake is submitting the NOI without payment, which guarantees the application is returned for resubmission. People wrongly believe the fee is annual, but it is a per-application charge tied to the five-year permit cycle.
Certification Block — Signature
This block legally binds the application. Type or print the name and title of the signer, then sign and date. The signer must be the right authority: for a corporation, a responsible corporate officer such as a president, vice-president, or an authorized plant manager; for a partnership or sole proprietorship, a general partner or the proprietor; for a public facility, a principal executive officer or ranking elected official. For example, Signed: PRIYA NATARAJAN, Title: Plant Manager, Date: 09 28 2026. The nuance: a plant manager can sign only if formally delegated authority to make environmental compliance decisions. The common mistake is having an office clerk or junior staffer sign, which invalidates the certification because they lack signing authority. Filers wrongly think any employee can sign, but federal rules name exactly who may, and false certification carries severe penalties.
Three Filled-Out Examples Using Real Scenarios
These three filers represent the most common industrial stormwater applicants in Ohio: a fabricated-metal shop, a scrap recycler, and a motor-freight terminal. Each walks through the NOI from top to bottom.
Scenario 1 — Priya at a fabricated metal products shop (Sector AA)
| Form Section | What Priya Enters |
|---|---|
| Company Name | MERIDIAN METAL WORKS LLC |
| Mailing Address | P.O. BOX 220, LORAIN, OH 44052 |

| Certification | PRIYA NATARAJAN, Plant Manager, 09 28 2026 |
Scenario 2 — Marcus at a scrap recycling facility (Sector N)
| Form Section | What Marcus Enters |
|---|---|
| Company Name | BUCKEYE SCRAP RECYCLING INC |
| Mailing Address | 1820 FOUNDRY ST, CANTON, OH 44707 |

| Payment | Check No. 4471, payable Treasurer, State of Ohio, $350.00 |
| Certification | MARCUS REED, President, 09 28 2026 |
Scenario 3 — Janet at a motor freight terminal (Sector P)
| Form Section | What Janet Enters |
|---|---|
| Company Name | OHIO VALLEY FREIGHT LINES INC |
| Mailing Address | 900 LOGISTICS DR, COLUMBUS, OH 43217 |
| Contact Person | JANET OKAFOR, 614-555-0173 |
| Facility Name | OHIO VALLEY FREIGHT – COLUMBUS TERMINAL |

| Receiving Stream / MS4 | CITY OF COLUMBUS (MS4) |
| Initial/Renewal | Renewal |
| Existing Permit Number | 0GR00742DG* |
| Primary SIC Code | 4213 |
| Outfall 001 | SIC 4213, Subsector P1, Not Applicable, Lat 39 56 44 Long -82 55 45 |
| Payment | ePayment $350.00 |
| Certification | JANET OKAFOR, Vice President of Operations, 09 28 2026 |
Across these three, notice how Aisha-style new filers mark Initial while Janet’s renewal must carry the existing permit number. A fifth filer worth picturing is Tom, an auto-salvage yard owner under Sector M (SIC 5015), who follows the same path but checks his Sector M benchmark duties in Part 8 of the permit.
How to File the Completed Form
Ohio EPA offers two filing channels, and the online channel is the standard one. Pick your channel before you finish data entry, because the payment method differs.
Online through the eBusiness Center is the required default. The URL is https://ebiz.epa.ohio.gov/. The fee is $350, paid by the built-in ePayment system using electronic check or card as offered. Processing time varies, but coverage is not legal until you receive the Director’s written approval letter, so do not begin discharging on the strength of submission alone. Keep your electronic confirmation, the submission receipt, and a PDF copy of the finished NOI as your proof of filing.
By mail under a hardship is the backup. Request a paper NOI, then mail it with a $350 check payable to Treasurer, State of Ohio to: Ohio Environmental Protection Agency, Office of Fiscal Administration, P.O. Box 1049, Columbus, OH 43216-1049. There is no fax option; the agency rejects faxed NOIs. Keep a copy of the signed NOI, the check number, and a certified-mail receipt as proof of filing.
Whichever channel you use, an incomplete NOI or one missing the fee is returned for resubmission, which restarts your timeline. File early enough to absorb a return, especially as a new facility bound by the 180-day-before-discharge window.
What Happens After You File
After submission, Ohio EPA reviews your NOI for completeness and eligibility against Part 1.1 of OHR000007. If everything checks out, the Director issues a written approval letter with your facility-specific permit ID, and that letter, not your submission, is the moment your coverage begins. Save the letter, because you will need its ID number when you renew.
Once covered, your real obligations kick in. You must implement your SWPPP, run routine facility inspections and quarterly visual assessments, and complete benchmark monitoring if your sector requires it; under OHR000007 the four quarterly benchmark samples are taken within the first eight quarters of coverage. The consequence of skipping these is concrete: Ohio EPA has issued Notices of Violation and enforcement orders to facilities that exceeded benchmark standards or failed to monitor.
If you ever stop the industrial discharge, you must close the loop by filing a Notice of Termination (NOT) through the eBusiness Center. Failing to file an NOT is itself a permit violation, so terminating coverage is not optional housekeeping; it is a legal step.
Mistakes to Avoid When Filling Out the Form
- Filing under the old OHR000006 number — it no longer grants coverage, so your discharge stays unauthorized.
- Submitting without the $350 fee — the NOI is returned and your timeline resets.
- Entering a P.O. Box as the facility address — the agency rejects it because it cannot inspect a box.
- Choosing the wrong SIC code — you land in the wrong sector and miss required benchmark monitoring.
- Swapping or under-precising the latitude/longitude — your site maps to the wrong watershed.
- Leaving the receiving stream blank — review stalls until the agency knows where runoff goes.
- Undercounting outfalls — you understate monitoring duties and create future violations.
- Marking “Initial” on a true renewal — you orphan your existing record and reset monitoring history.
- Omitting the existing permit number on renewal — coverage continuity breaks.
- Letting an unauthorized person sign — the certification is invalid and exposes you to false-certification penalties.
- Filing the NOI with no SWPPP in place — you certify to a plan that does not exist.
- Discharging before the approval letter arrives — submission is not authorization, and early discharge is unpermitted.
Do’s and Don’ts
Do’s
- Build your SWPPP first, because you certify you will implement it the moment you file.
- Verify your SIC code on the OSHA tool, since it drives your entire monitoring path.
- Request your eBusiness PIN early, as it can take days and you cannot submit without it.
- Take coordinates from the center of your site, so the mapped discharge point is accurate.
- Pay by ePayment when filing online, which avoids lost-check delays.
- Save the Director’s approval letter, because its ID number is your proof of coverage at renewal.
Don’ts
- Don’t fax the NOI, because Ohio EPA never accepts faxed applications.
- Don’t reuse one NOI for multiple sites, since coverage is site-specific.
- Don’t guess the receiving water, as a wrong name undermines the agency’s review.
- Don’t let a junior employee sign, because only named officers or proprietors may certify.
- Don’t begin discharging on submission alone, since coverage starts only at written approval.
- Don’t ignore the renewal re-notify letter, because you have just 90 days to act.
Pros and Cons of Filing on Your Own vs. With a Consultant
| Filing It Yourself | Hiring a Consultant |
|---|---|
| Saves money — you pay only the $350 fee and no professional fees. | Costs more, but a pro absorbs the fee plus their billable hours. |
| Builds in-house knowledge of your own SWPPP and monitoring. | Brings expertise that gets the SIC code and outfalls right the first time. |
| Full control over timing, so you file when you are ready. | Saves time, freeing your staff from learning the eBusiness system. |
| Risk of errors is higher if you have never filed before. | Lower error risk, since consultants file these routinely. |
| You must learn benchmark and inspection rules on your own. | Reduces violation risk by setting up monitoring correctly from day one. |
A useful rule of thumb: a single-outfall fabricated-metal shop with a clear SIC code can reasonably self-file, while a multi-outfall scrap yard subject to benchmark monitoring often benefits from a consultant’s eye.
Related Forms and How They Differ
| Form | What It Does |
|---|---|
| Notice of Intent (NOI) | Applies for or renews coverage under OHR000007. |
| Notice of Termination (NOT) | Ends coverage once the industrial discharge stops; required, not optional. |
| No Exposure Certification (NOE) | Certifies industrial activity is fully sheltered from rain, exempting you from permitting; re-filed every five years. |
| Individual NPDES Permit (Form 1) | Required when you are ineligible for the general permit or have other waste streams. |
The misconception many filers carry is that the No Exposure Certification and the NOI are interchangeable. They are not. The NOE says rain never touches your industrial materials, while the NOI says it does and you will manage it. Choosing the wrong one either leaves you unpermitted or burdens you with monitoring you don’t owe.
FAQs
Do I need this permit if my facility is small?
Yes. Size does not matter. If industrial materials or activities are exposed to rain and runoff leaves your site, you must obtain coverage regardless of how small the operation is.
Is the OHR000007 permit the current version I should use?
Yes. OHR000007 took effect June 1, 2022 and replaced OHR000006. File under OHR000007; the older number no longer grants valid coverage.
Do I write a P.O. Box in the Facility Address field?
No. The facility address must be a physical street location with county, because Ohio EPA needs to locate and inspect the site. P.O. Boxes are allowed only in the mailing address field.
Does my coverage start as soon as I submit the NOI?
No. Coverage begins only when you receive the Director’s written approval letter. Discharging before that letter arrives is an unpermitted, unlawful discharge.
Do I enter my primary SIC code or my outfall SIC code in Section III?
Yes, both appear. Your single primary SIC code goes in the Primary SIC field, while each outfall gets the SIC code for the area draining to it in the Outfall Information grouping.
Is the $350 fee charged every year?
No. The $350 is a per-application fee tied to the five-year permit cycle, paid when you file the NOI, not annually.
Do I use decimal or degrees-minutes-seconds for coordinates?
Yes, it depends on the field. The facility latitude/longitude uses decimal format to six places, while each outfall’s coordinates use degrees-minutes-seconds with two digits each.
Can my office assistant sign the certification?
No. Only a responsible corporate officer, a general partner or proprietor, or a ranking public official may sign. An unauthorized signature invalidates the certification.
Do I need a SWPPP before I file the NOI?
Yes. Your Stormwater Pollution Prevention Plan must be developed before filing, because you certify on the NOI that you will implement it.
Is faxing the NOI an option if my internet is down?
No. Ohio EPA never accepts faxed NOIs. The standard channel is the eBusiness Center, with hardship paper mailing as the only backup.
Do I file a Notice of Termination when I close the discharge?
Yes. Once the regulated stormwater discharge ends, you must submit an NOT through the eBusiness Center. Failing to do so is a permit violation.
Does the No Exposure Certification replace the NOI?
No. The No Exposure Certification applies only when industrial activities are fully sheltered from rain. If runoff contacts industrial materials, you need the NOI instead.
Do I have to re-notify when the permit is renewed?
Yes. Existing facilities must submit a new NOI within 90 days of Ohio EPA’s written re-notify instructions. Renewal is not automatic.
Is benchmark monitoring required for every facility?
No. Benchmark monitoring depends on your sector and subsector under Part 8 of the permit. Check your subsector to confirm whether quarterly sampling applies to you.
