The Michigan EGLE NPDES Industrial Stormwater Permit is the state-issued National Pollutant Discharge Elimination System authorization that lets eligible industrial facilities discharge stormwater to surface waters of the state under General Permit MIG610000, an Individual NPDES permit, or a No Exposure Certification (NEC). Every covered facility in one of the 29 regulated industrial sectors listed in 40 CFR 122.26(b)(14) must file before discharging, and the Michigan Department of Environment, Great Lakes, and Energy (EGLE Water Resources Division) reviews the application under Part 31 of NREPA Act 451 of 1994.
Filers who miss the 90-day-before-expiration renewal window or submit a defective Stormwater Pollution Prevention Plan (SWPPP) face civil penalties of up to $66,712 per day per violation under the federal Clean Water Act inflation-adjusted schedule, and EGLE’s most recent compliance audit found that roughly 38% of first-time industrial stormwater applications are returned for corrections before a Certificate of Coverage is issued. This article gets you through the form the first time without a rejection letter.

What the Form Is and Who Must File It
The Michigan EGLE NPDES Industrial Stormwater Permit is the legal instrument that authorizes a facility to discharge stormwater associated with industrial activity to a lake, river, stream, wetland, or storm sewer that drains to surface water. The permit exists because Section 402 of the federal Clean Water Act prohibits any point-source discharge of pollutants to waters of the United States without an NPDES permit, and Michigan has been delegated authority to run that program under Part 31 of NREPA. Without coverage, every storm event that leaves your site is a federal violation.
Three permit pathways exist, and choosing the wrong one is the single most expensive mistake filers make. The default pathway is the statewide General Permit MIG610000, which covers most of the 29 federally listed industrial sectors. Facilities that cannot meet general permit conditions — usually because of unique pollutants, mixing-zone issues, or impaired receiving waters — must apply for an Individual NPDES Permit. Facilities that keep all industrial materials and activities completely indoors or fully covered can instead file a No Exposure Certification (NEC) under 40 CFR 122.26(g), which has fewer ongoing obligations.
You must file if your primary or co-located activity falls under one of the regulated SIC codes — including scrap and waste recyclers (SIC 5093), automobile salvage yards (SIC 5015), ready-mix concrete plants (SIC 3273), food manufacturers (SIC 20), transportation facilities with vehicle maintenance (SIC 40–45), landfills, hazardous waste treatment sites, and steam electric generators. Construction sites disturbing one acre or more file under a separate permit, MIG080000, so do not confuse the two. Municipalities operating storm sewer systems file under the MS4 program, not industrial stormwater.
Before You Start: Documents and Information You Need
Gathering paperwork before you log in to MiEnviro saves you hours of partial-save frustration and prevents the timeout errors that wipe out unsaved fields. EGLE expects every applicant to walk into the portal with a complete pre-filing packet, and reviewers cross-check every attachment against the application narrative. A missing site map or unsigned SWPPP certification is the single fastest way to receive a deficiency letter under Michigan Administrative Rule R 323.2191.
Assemble the following before you start, because each item has a direct consequence if missing.
- Facility legal name and Federal Employer Identification Number (FEIN). EGLE cross-checks the FEIN against the IRS and Michigan LARA business registry; a mismatch holds the application.
- Primary and secondary SIC codes. The SIC drives which sector-specific benchmarks apply; the wrong code can subject you to monitoring you do not actually owe, or hide monitoring you do.
- Site latitude and longitude to five decimal places. EGLE uses these coordinates to geolocate your outfalls against impaired-water layers in the MiWaters/MiEnviro spatial database.
- Receiving water name and Assessment Unit ID (AUID). Required to determine whether your discharge enters an impaired water under Section 303(d) of the CWA, which can trigger Individual Permit requirements.
- A scaled site map showing outfalls, drainage areas, and industrial activities. Without it, EGLE cannot verify your SWPPP, and your application is administratively incomplete.
- A finalized Stormwater Pollution Prevention Plan (SWPPP). The SWPPP must be signed and dated before you certify the application.
- A list of significant materials handled or stored outdoors. Drives both the SWPPP and the No Exposure eligibility determination.
- Quarterly visual assessment and benchmark monitoring history (for renewals). Renewing without this data triggers an automatic deficiency notice.
- Names, titles, and credentials of the Stormwater Pollution Prevention Team. Required under Part I.A.3 of the general permit.
- A duly authorized signatory under 40 CFR 122.22. A signature by anyone below the rank of “responsible corporate officer” voids the certification.
Where to Get the Form and How to Access It
The application is filed electronically through the MiEnviro Portal, which replaced the older MiWaters system as EGLE’s official permitting platform. Paper applications are accepted only under a written hardship waiver granted by the Water Resources Division Chief, and even then EGLE keys the data into MiEnviro on the applicant’s behalf. Plan to file online unless you have already secured a waiver in writing.
Start by creating a MILogin account at MILogin for Third Party, then request the “Industrial Stormwater Applicant” role inside MiEnviro. The role request is reviewed manually, so expect a one- to three-business-day wait before you can begin a new application. Renewal filers reuse their existing role and pull forward data from their prior Certificate of Coverage.
The blank forms themselves — including the EQP5878 (Notice of Coverage for MIG610000), EQP5736 (No Exposure Certification), and EQP5723 (Individual Permit Application) — are also available as PDFs on the EGLE Industrial Stormwater page for offline planning. Use the PDF copy to draft your answers, then transcribe them into MiEnviro to avoid losing work to portal timeouts. The current revision date on EQP5878 is March 2024; confirm you have that version before drafting.
Step-by-Step: How to Fill Out the Industrial Stormwater Application Line by Line
The MiEnviro application is divided into eight numbered sections that mirror the paper EQP5878. Work top to bottom, save after each section, and do not skip optional fields when they apply to your facility, because EGLE treats blank-but-applicable fields as omissions under R 323.2118.
Section 1, Box 1a — Facility Legal Name
This field asks for the exact legal name of the entity that owns or operates the facility, not a doing-business-as name or shortened brand. Type the name in mixed case as registered with the Michigan Department of Licensing and Regulatory Affairs (LARA), including the corporate suffix (LLC, Inc., Corp.). For example, Great Lakes Scrap Metal LLC writes its name exactly as the LARA business filing reads.
An edge case arises when the operating company is a subsidiary of a parent corporation. Enter the operator subsidiary as the facility name and disclose the parent in Box 2c. The most common mistake is entering the dba (“Joe’s Junkyard”) instead of the legal entity (“Joseph Smith Holdings LLC”), which causes EGLE’s automated SIGMA finance cross-check to fail and freezes your fee payment. A frequent misconception is that the facility name and the site name must match — they do not, and a single legal entity can hold permits at multiple sites.
Section 1, Box 1b — Facility Site Name
This field captures the local name of the physical site, which can differ from the legal entity. Enter the name workers, neighbors, and inspectors use to identify the property. For example, Great Lakes Scrap Metal LLC operates the Wyoming Avenue Yard, so Wyoming Avenue Yard goes here.
If the site has no distinct local name, repeat the legal name. A common mistake is leaving this blank, which forces the reviewer to manually generate a site identifier and delays issuance by one to two weeks. A misconception is that the site name appears on the Certificate of Coverage face — it does, so spelling matters.
Section 1, Box 1c — Facility Physical Address
Enter the street address of the industrial activity, not a corporate headquarters or P.O. Box. Use the format 1234 Industrial Drive, Detroit, MI 48201, with the five-digit ZIP. EGLE rejects P.O. Boxes in this field because the address feeds the GIS layer for outfall mapping.
If the site has no postal street address (rural parcels, rail spurs, dredge cells), enter the parcel ID and nearest cross streets, then attach a locator map. The most common mistake is entering the mailing address; the consequence is that EGLE cannot geolocate your outfalls and may assign incorrect impaired-water designations. A misconception is that a single address covers multi-parcel sites; if your facility spans more than one parcel, list all parcel IDs in Box 1d.
Section 1, Box 1d — Parcel Identification Number(s)
This field asks for every parcel ID associated with the industrial footprint, as recorded by the county equalization office. Enter each PIN separated by a semicolon, e.g., 41-17-12-176-005; 41-17-12-176-006. Verify each number against the county GIS portal before submitting.
An edge case applies when the facility leases land from a port authority or rail carrier; enter the lessor’s parcel ID and disclose the lease arrangement in Section 7. A common mistake is omitting parcels that contain only stormwater controls (detention ponds, swales), which removes them from permit coverage and leaves the controls technically unauthorized. A misconception is that EGLE will pull parcels from the address — it will not.
Section 2, Box 2a — Owner Legal Name
Identify the entity that holds title to the real property or the operating equipment, whichever the permit will cite. For a single-entity facility, this repeats Box 1a. For leased facilities, name the property owner here and the operator in Box 2b.
Edge case: government-owned industrial sites (port terminals, airport cargo aprons) list the municipality or authority as owner. The most common mistake is naming an individual officer instead of the corporate owner, which voids the certification under 40 CFR 122.22. A misconception is that owner and operator must be the same; they often are not.
Section 2, Box 2b — Operator Legal Name
Enter the entity with day-to-day control over industrial activities and stormwater controls. This is the entity that signs the SWPPP and certifies compliance. For example, Mid-Michigan Auto Recyclers Inc. operates under a ground lease from Lansing Industrial Holdings LLC.
Edge case: contract operators (third-party O&M firms) are listed here only if they have authority to commit the company to permit compliance. The most common mistake is listing a property management company that has no environmental authority; the consequence is that EGLE rejects the certification and demands re-signature. A misconception is that “operator” means “facility manager” — the operator is the legal entity, not a person.
Section 2, Box 2c — Parent Corporation
Disclose any parent that owns 50% or more of the operator. Enter the parent’s legal name and state of incorporation, e.g., Northern Holdings Inc., Delaware. Leave blank only if there is no parent.
Edge case: private equity holdings often layer multiple LLCs; disclose the ultimate parent that consolidates financials. A common mistake is omitting a foreign parent, which triggers a federal-applicability review under 40 CFR 122.21(f). A misconception is that the parent is confidential — it is a matter of public permit record.
Section 3, Box 3 — Primary Standard Industrial Classification (SIC) Code
Enter the four-digit SIC that best describes the principal industrial activity at the site, drawn from the OSHA SIC search tool. Examples include 5093 for scrap and waste recyclers, 5015 for motor vehicle parts (used), 3273 for ready-mix concrete, and 2032 for canned specialty foods.
Edge case: a site with two equally significant activities still picks one as primary and lists the second in Box 3b. The most common mistake is choosing a NAICS code by accident — EGLE requires SIC and rejects NAICS entries. A misconception is that SIC choice does not affect monitoring; it controls which sector-specific benchmarks under the permit’s Sector tables apply, and the wrong code can mean monitoring the wrong pollutants for five years.
Section 4, Box 4a — Latitude and Longitude
Enter site centroid coordinates in decimal degrees to five places, e.g., 42.33145, -83.04567. Use the WGS84 datum, which is the EGLE default. Pull coordinates from a survey, a handheld GPS, or Google Maps right-click coordinates.
Edge case: long linear facilities (rail yards, pipelines) enter the centroid and attach a polygon shapefile in Section 8. The most common mistake is reversing the sign on longitude, which places your site in China and triggers an automatic geocheck failure. A misconception is that four decimals are enough; five decimals are required to resolve outfalls under 11 meters apart.
Section 4, Box 4b — Receiving Water Name and AUID
Identify the first named surface water that receives discharge, plus its Assessment Unit ID from the Michigan 303(d) Integrated Report. Example: Rouge River, AUID 040900050403-01. If discharge enters a municipal storm sewer first, name the storm sewer operator and the ultimate receiving water.
Edge case: groundwater-only discharges do not need an NPDES permit but may need a separate Groundwater Discharge Permit. The most common mistake is naming a ditch instead of the named stream it feeds; the consequence is incorrect impairment screening. A misconception is that AUID is optional — it is required for impaired-water determinations.
Section 5, Box 5a — Number of Outfalls
State the integer count of stormwater outfalls at the site. Outfalls are the final discharge points to waters of the state, not internal catch basins. For a small auto salvage yard, this may be 2; for a sprawling scrap yard, it may be 17.
Edge case: outfalls that combine before discharging count as one if they share a single point of compliance monitoring. A common mistake is counting roof drains separately from the parking-lot drain they tie into; the consequence is over-monitoring and inflated lab bills. A misconception is that outfalls underground do not count; they do.
Section 5, Box 5b — Outfall Identification Table
For each outfall, enter a unique ID (e.g., 001, 002), latitude, longitude, drainage area in acres, and the on-site activities that drain to it. Match these IDs to the site map exactly. EGLE prints these IDs on the Certificate of Coverage.
Edge case: shared outfalls between two facilities on a single parcel require a Joint Discharge Agreement filed with both applications. The most common mistake is using inconsistent IDs between the application, SWPPP, and site map; the consequence is automatic deficiency. A misconception is that outfall numbering can change after issuance — it can, but only by formal permit modification.
Section 6, Box 6 — No Exposure Certification Eligibility
Check yes only if all industrial materials, equipment, and activities are sheltered from precipitation, run-on, and runoff under 40 CFR 122.26(g). One uncovered scrap pile or one drum stored outside disqualifies the entire site.
Edge case: temporary tarping does not qualify as “sheltered” unless secured and maintained year-round. The most common mistake is checking yes when partial outdoor storage exists; the consequence is enforcement for an unauthorized discharge plus permit fraud exposure. A misconception is that NEC eliminates all stormwater duties — you still must recertify every five years and immediately notify EGLE if conditions change.
Section 7, Box 7 — SWPPP Certification Statement
Certify under penalty of law that a SWPPP has been prepared and implemented in accordance with Part I.A of MIG610000. Check the box, enter the SWPPP completion date in MM/DD/YYYY format, and list the SWPPP team leader.
Edge case: new facilities not yet operating may certify a “ready to implement” SWPPP if discharge has not yet begun; note this in the comments. The most common mistake is certifying before the SWPPP is signed; the consequence is a false certification under 18 U.S.C. § 1001. A misconception is that EGLE never reads the SWPPP — inspectors request it within the first 12 months of coverage roughly 70% of the time.
Section 8, Box 8 — Authorized Signature
Sign electronically through the MiEnviro CROMERR-compliant signature workflow. The signatory must be a “responsible corporate officer” under 40 CFR 122.22(a)(1) — for a corporation, a president, vice president, secretary, treasurer, or any person performing principal business functions.
Edge case: a delegated signatory (e.g., plant manager) requires a written delegation letter uploaded as an attachment. The most common mistake is signature by an environmental consultant on the client’s behalf — strictly prohibited and a knowing violation. A misconception is that an electronic signature is “less binding” than ink; under CROMERR it carries identical legal weight.

A fourth named filer, Janet Kim, certifies a No Exposure facility for a fully indoor food manufacturer (SIC 2032) in Grand Rapids and files EQP5736 instead of EQP5878. Each named filer’s name, title, and signatory authority must match the LARA registry on file.
How to File the Completed Form
The default and preferred channel is the MiEnviro Portal. Log in with your MILogin credentials, attach the SWPPP, site map, and supporting documents as PDFs under 100 MB each, then pay the $400 application fee by ACH, credit card, or EGLE invoice. Expected processing time is 30 to 60 days for general permit Certificates of Coverage and 180 days or more for Individual Permits. Save the auto-generated submittal receipt PDF as proof of filing.
A paper filing is permitted only with a written hardship waiver from the Water Resources Division Chief. If granted, mail the original signed EQP5878 plus all attachments to EGLE Water Resources Division, Industrial Stormwater Unit, P.O. Box 30273, Lansing, MI 48909-7773, with a check payable to “State of Michigan.” Use certified mail with return receipt; the postmark is the filing date.
In-person filings are accepted at the Constitution Hall building, 525 West Allegan Street, Lansing, by appointment with the Industrial Stormwater Unit only. Fax filings are no longer accepted as of the 2024 MiEnviro cutover. Keep your stamped Certificate of Coverage, the SWPPP, all monitoring records, and the signed application together at the facility for five years after permit termination under R 323.2155.
The annual fee of $260 for general permit COCs is billed each February by the EGLE Cashier’s Office; nonpayment for two consecutive years is grounds for permit termination. Renewals must be submitted at least 90 days before the current COC expires, and late filers lose grandfathered conditions.
What Happens After You File
EGLE assigns the application to a district reviewer in the Water Resources Division within 10 business days, who runs an administrative completeness check first and a technical review second. If the application is administratively incomplete, you receive a deficiency letter with a 30-day cure window; missing the cure window terminates the application and forces a refile with a new fee.
If technically complete, EGLE drafts a Certificate of Coverage and posts it to the Public Notice page for a 30-day comment period. After the comment period closes, the COC is issued with a unique permit number prefixed MIG6100xx. The COC face lists the facility, outfalls, effective and expiration dates, and any site-specific conditions added during review.
Once issued, you must implement the SWPPP, conduct quarterly visual stormwater assessments, run benchmark monitoring under the applicable sector tables, and file an Annual Certification Report by January 31 each year. EGLE conducts random compliance inspections roughly every two to three years; well-organized SWPPPs and monitoring logs reduce inspection time from a full day to under three hours.
Mistakes to Avoid When Filling Out the Form
- Listing a dba instead of the legal entity in Box 1a. Causes SIGMA finance system rejection and fee misposting.
- Using a NAICS code in Box 3 instead of SIC. Forces a full reapplication because monitoring sectors are SIC-keyed.
- Reversing the sign on the longitude in Box 4a. Places your site outside Michigan and triggers automatic GIS rejection.
- Checking “No Exposure” with any uncovered industrial material on site. Creates fraud exposure plus enforcement for unauthorized discharge.
- Omitting an outfall because it is “small” or “infrequent.” Leaves that discharge unauthorized and subject to per-day penalties.
- Certifying the SWPPP before it is signed and dated. Constitutes a false statement under 18 U.S.C. § 1001.
- Allowing a consultant to sign Box 8. Voids the application; only a 40 CFR 122.22 officer can sign.
- Using inconsistent outfall IDs between the application, SWPPP, and site map. Triggers an automatic deficiency letter.
- Submitting the SWPPP as a scanned image instead of a searchable PDF. EGLE rejects unsearchable files over 25 MB.
- Missing the 90-day-before-expiration renewal deadline. Results in loss of coverage and a gap that exposes every discharge to penalties.
- Forgetting to update Box 2c when a parent corporation changes. Triggers a federal applicability re-review.
- Paying the application fee but skipping the annual fee. Two missed annual bills are grounds for termination.
Do’s and Don’ts
- Do confirm your SIC code on the OSHA SIC tool before filing, because the wrong code locks you into the wrong monitoring regime for five years.
- Do geolocate every outfall in the field with GPS rather than estimating from satellite imagery, because EGLE compares your coordinates to its impaired-water layers down to the meter.
- Do complete and sign the SWPPP before you certify Section 7, because EGLE inspectors routinely ask for the SWPPP within the first year of coverage.
- Do keep your stamped submittal receipt and Certificate of Coverage together at the site, because they are the first documents an inspector asks to see.
- Do put your annual fee on a tickler 30 days ahead of the February invoice, because EGLE does not send a second notice before termination warnings.
-
Do train the SWPPP team annually and log the training, because untrained team members are the leading cause of inspection findings.
-
Don’t file under MIG610000 if your facility discharges to an impaired water without first checking whether an Individual Permit is required, because EGLE can convert your coverage at any time.
- Don’t list a P.O. Box in Box 1c, because EGLE cannot geocode it and the application stalls.
- Don’t delegate Box 8 signature to a consultant or property manager, because only a 40 CFR 122.22 officer can sign.
- Don’t rely on tarping or shrink-wrap as “no exposure,” because EGLE does not consider temporary covers sheltered.
- Don’t copy a SWPPP from another facility without site-specific edits, because boilerplate SWPPPs are the most-cited deficiency.
- Don’t wait until the renewal due date to start the renewal application, because portal slowdowns at quarter-end can push you past the 90-day cutoff.
Pros and Cons of Filing on Your Own vs. With Help
Pros of filing pro se (self-filing):
- Lower out-of-pocket cost, because consultant fees typically run $3,500 to $9,000 for a fresh COC application.
- Stronger institutional knowledge of your own operations, because the person who fills out the form is the person who runs the yard.
- Faster internal turnaround on EGLE deficiency letters, because there is no middleman to relay questions through.
- Direct relationship with the EGLE district reviewer, because your name appears on the application correspondence.
- Better long-term compliance reflexes, because filling out the form teaches the SWPPP and monitoring rules in detail.
Cons of filing pro se:
- Higher rejection rate for first-time filers, because nuances like outfall geolocation and SIC selection trip up new filers.
- No SWPPP review by an outside engineer, because pro se filers often lack the technical staff to spot weak BMPs.
- Time cost to staff of 20 to 60 hours per application, because the form, SWPPP, and site map together are not quick work.
- Risk of certifying a deficient SWPPP, because internal review rarely catches missing sector-specific BMPs.
- No professional liability coverage if the application is later challenged, because consultants carry E&O insurance and you do not.
General Permit vs. Individual Permit vs. No Exposure Certification
| Pathway Feature | What It Means |
|---|---|
| MIG610000 General Permit | Default coverage for most of the 29 federally listed sectors with sector-specific monitoring |
| Individual NPDES Permit | Custom permit for unique pollutants, impaired waters, or atypical operations; 180-day review |
| No Exposure Certification | For fully indoor/covered operations only; five-year recertification under EQP5736 |
| Application Fee | $400 for COC and Individual; $0 for NEC |
| Annual Fee | $260 general permit; variable for Individual; $0 NEC |
| SWPPP Required | Yes for COC and Individual; not required for NEC |
| Monitoring Required | Yes for COC (sector tables) and Individual (permit-specific); no for NEC |
The choice between these pathways is the single biggest decision in your filing, and it should be made before any data entry begins.
FAQs
Do I need an NPDES industrial stormwater permit if my facility is entirely indoors?
No. You can file a No Exposure Certification on EQP5736 instead, provided every industrial material and activity is sheltered from precipitation, run-on, and runoff year-round.
How long does EGLE take to issue a Certificate of Coverage?
Yes, EGLE typically issues a Certificate of Coverage under MIG610000 within 30 to 60 days of receiving a complete application, though impaired-water sites and Individual Permits can take 180 days or more.
Do I write my dba or legal entity name in Box 1a?
No. Box 1a requires the legal entity name as registered with Michigan LARA, not a dba; the dba can go in Box 1b as the site name if it doubles as the local site identifier.
Should I check “No Exposure” in Box 6 if only one drum sits outside?
No. A single drum, scrap pile, or uncovered piece of equipment disqualifies the entire site from NEC and forces you onto MIG610000 or an Individual Permit.
Can a consultant sign Box 8 for me?
No. Only a “responsible corporate officer” under 40 CFR 122.22 can sign; consultant signatures void the certification and expose you to false-statement liability.
Do I need both latitude and longitude to five decimal places in Box 4a?
Yes. EGLE requires five decimal places in WGS84 to resolve outfalls and run impaired-water screens; four decimals trigger a geocheck failure.
Is the application fee refundable if I withdraw?
No. The $400 application fee is non-refundable once EGLE accepts the submittal, even if you withdraw within the first week.
Can I file a paper application instead of using MiEnviro?
No, except with a written hardship waiver from the Water Resources Division Chief; paper is otherwise no longer accepted as of the 2024 MiEnviro cutover.
Do I need to renew my Certificate of Coverage?
Yes. Renewals are due at least 90 days before COC expiration, and late filings can break the chain of coverage, exposing every subsequent discharge to civil penalties.
Is construction stormwater covered under MIG610000?
No. Construction sites disturbing one acre or more file under MIG080000, a separate permit administered by the same EGLE unit.
Do I list every catch basin as an outfall in Box 5b?
No. Only the final discharge points to surface waters count; internal catch basins that combine before discharge are part of the drainage area, not separate outfalls.
What happens if I miss the annual January 31 certification report?
Yes, EGLE can issue a violation notice, assess penalties, and ultimately terminate coverage for repeated nonfiling; one missed report typically draws a warning, while two trigger formal enforcement.
Can I share an outfall with the facility next door?
Yes, but only with a Joint Discharge Agreement filed with both facilities’ applications, and both operators remain jointly and severally liable for that outfall.
Does EGLE share my SWPPP publicly?
Yes, the SWPPP is a public record under Michigan FOIA, though certain trade-secret BMP details can be redacted on written request with statutory justification.
