The Illinois IEPA Wastewater Treatment Permit is the legal authorization issued by the Illinois Environmental Protection Agency Bureau of Water that lets a person, business, municipality, or developer build, modify, or discharge from a wastewater treatment works in Illinois. It is filed by anyone who plans to construct a treatment system, operate a publicly owned treatment works (POTW), or release treated water into a lake, river, or sewer system inside the state.
Illinois processes more than 1,800 active National Pollutant Discharge Elimination System (NPDES) permits each year, and the agency reports that roughly 30% of first-time applications come back for correction because of missing attachments or incomplete effluent data, according to the Illinois EPA Bureau of Water permit program. Getting the form right the first time saves months of back-and-forth and protects you from civil penalties of up to $50,000 per day under 415 ILCS 5/42.
Here is what you will learn in this guide:
- 📝 How each box, line, and signature block on the IEPA wastewater forms works in plain English
- 🏭 Which permit fits your situation: NPDES Individual, Construction (WPC-PS-2), General, or Pretreatment
- 📅 Deadlines, fees, and penalty exposure under the Illinois Environmental Protection Act
- 🗂️ The exact attachments and engineering documents you must gather before you start
- 🚫 The most common mistakes filers make and how to avoid a Notice of Deficiency
What the Form Is and Who Must File It
The Illinois IEPA Wastewater Treatment Permit is actually a family of forms governed by the Illinois Environmental Protection Act, 415 ILCS 5 and 35 Ill. Adm. Code Part 309. The two most common are the NPDES Individual Permit application (Form WPC-PS-1, IL 532-0061) used for direct discharges to waters of the state, and the Construction Permit application Form WPC-PS-2 used to build or modify a treatment works. Each form has a revision date printed in the lower right corner; confirm you are using the most recent version before you file.
You must file if you operate or build a treatment works that discharges to a river, lake, or stream, if you run a publicly owned treatment works serving a city or village, if you own an industrial facility that discharges process wastewater, if you are a developer adding a package plant to a subdivision, or if you run a Concentrated Animal Feeding Operation (CAFO) above the regulatory threshold. Federal authority flows from Clean Water Act §402, which delegates NPDES permitting to Illinois.
Pretreatment dischargers who send industrial wastewater to a POTW (such as a brewery sending high-BOD waste to a city sewer) may also need authorization from the receiving treatment works under the federal pretreatment program at 40 CFR 403. In the Chicago region, the Metropolitan Water Reclamation District (MWRD) issues its own pretreatment permits that overlap with IEPA jurisdiction.
Before You Start: Documents and Information You Need
Open a folder and gather every item below before you touch the form. Missing one piece is the single most common reason an application stalls inside the IEPA permit review queue.
- Federal Employer Identification Number (FEIN) or Social Security Number. The agency uses this to match your application to billing and enforcement records; a mismatch can suspend processing.
- Facility latitude and longitude in decimal degrees to four places. IEPA cross-checks the point against its GIS layers, and a wrong coordinate puts the discharge in the wrong watershed.
- USGS 7.5-minute topographic site map. You must mark each outfall with a labeled arrow; staff use the map to verify receiving water classification.
- Process flow diagram and schematic of every treatment unit. Reviewers compare flow rates against design capacity, and a missing unit triggers an automatic incompleteness letter.
- Standard Industrial Classification (SIC) and NAICS codes. These drive which effluent guidelines apply under 40 CFR Subchapter N.
- Form 2C analytical data for industrial dischargers. You need at least one full priority pollutant scan from a NELAP-accredited lab.
- Antidegradation demonstration under 35 Ill. Adm. Code 302.105 for any new or expanded discharge.
- Sludge (biosolids) management plan describing how residuals are handled under 35 Ill. Adm. Code Part 391.
- Engineering plans and specifications sealed by an Illinois-licensed Professional Engineer. Required for every construction permit under 225 ILCS 325.
- Filing fee payment. Calculate the fee using the schedule in 415 ILCS 5/12.5 and have a check or ACH ready.
Where to Get the Form and How to Access It
All current wastewater permit forms live on the IEPA Bureau of Water forms page. Download the PDF directly from the agency rather than a third-party site so you have the latest revision. The two-page header of every form lists the revision number; if you pull an older version your filing can be rejected on intake.
For digital submissions, IEPA accepts applications through the federal NetDMR system for discharge monitoring reports and through the agency’s secure email portal for new applications. Construction permit applications can be uploaded to the IEPA Document Management System once you have an account.
You can also pick up paper forms in person at IEPA headquarters at 1021 North Grand Avenue East, Springfield, IL 62702. The Bureau of Water permit section answers form questions at (217) 782-0610. If you need an accessibility accommodation, request one through the IEPA accessibility office at least five business days before filing.
Step-by-Step: How to Fill Out the IEPA Wastewater Permit Line by Line
Below is the line-by-line walkthrough using the NPDES Individual Permit application (Form WPC-PS-1) as the spine, with construction-permit (WPC-PS-2) callouts where the fields differ.
Section A, Box 1: Applicant Legal Name
This box asks for the exact legal name of the person or entity that will hold the permit. Write the name as it appears on your Illinois Secretary of State registration, your articles of incorporation, or your DBA filing. Use ALL CAPS only if the form prints in caps; otherwise use normal case.
For example, Riverbend Brewing Company, LLC writes its full LLC name, not the brand name “Riverbend Beer.” A municipality writes Village of Mahomet, not “Mahomet.”
A common edge case is a parent-subsidiary structure. If a holding company owns the plant but a subsidiary operates it, the operator goes in Box 1 and the owner goes in Box 2. The most common mistake is using a marketing name, which causes the permit to issue to a non-existent legal entity and invalidates enforcement protection. Many filers think the “doing business as” name is fine here; it is not, because IEPA matches Box 1 against the Secretary of State database.
Section A, Box 2: Facility Owner
This field captures who owns the land and the treatment works. List the legal owner exactly, including any trust or LLC.
For example, Mahomet Sanitary District enters its district name; Riverbend Brewing Holdings, LLC enters the holding company. If owner and operator are the same, write “SAME AS BOX 1.”
Edge case: leased facilities. If you lease the treatment works from a landlord, list the landlord here and attach the lease summary. The most common mistake is leaving this blank when the operator is also the owner; reviewers read blank fields as incomplete and send a Notice of Deficiency. A frequent misconception is that ownership only matters at issuance; in fact, ownership transfer triggers a permit transfer requirement under 35 Ill. Adm. Code 309.181.
Section A, Box 3: Facility Mailing Address and Physical Location
The mailing address gets all written correspondence; the physical location is where the plant sits. Write both, even when they are identical, and use the format Street / City / State / ZIP.
For example, Riverbend Brewing Company, LLC writes mailing address 742 Industrial Park Dr., Decatur, IL 62526 and physical location Same. A village might list a P.O. Box for mail and a street for the plant.
The edge case is rural facilities with no street number; in that case use the 911 address assigned by the county. The common mistake is using a P.O. Box in the physical-location half, which makes site inspections impossible and triggers a deficiency letter. Filers often think the mailing address controls jurisdiction; the physical coordinates do, because the receiving water and watershed are tied to the site.
Section A, Box 4: Latitude and Longitude
Enter the coordinates of the discharge point (the outfall) in decimal degrees to at least four decimal places. Use the WGS84 datum, which is the IEPA standard.
For example, an outfall at 39.8403° N, 88.9548° W is written 39.8403 / -88.9548. Pull the value from a survey or from the USGS National Map viewer.
Edge case: multiple outfalls. List the primary outfall here and add the rest on a continuation sheet labeled “Additional Outfalls.” The most common mistake is entering degrees-minutes-seconds when the form asks for decimal degrees, which puts the discharge point miles from the real location. A misconception is that “close enough” works; IEPA’s GIS routes the point to the wrong watershed if you are off by even 0.01 degree.
Section A, Box 5: SIC and NAICS Codes
This box asks for the four-digit SIC code and the six-digit NAICS code that describe your primary activity. Look these up on the North American Industry Classification System search tool.
For example, a brewery enters SIC 2082 and NAICS 312120. A municipal POTW enters SIC 4952 and NAICS 221320.
The edge case is mixed-use facilities; in that case use the code that represents the largest fraction of wastewater volume and list the secondary code in the comments. The common mistake is choosing a generic code such as 9999, which forces a manual review and adds weeks to processing. A widely held misconception is that the SIC code is optional because NAICS replaced it; IEPA still requires both because federal effluent guidelines are organized by SIC.
Section B, Box 6: Type of Permit Requested
Check the box that matches your action: New, Renewal, Modification, or Transfer. Only one box gets checked.
For example, a village whose permit expires in 2027 checks Renewal; a developer building a new package plant checks New. Riverbend Brewing expanding production checks Modification.
Edge case: simultaneous renewal and modification. File a renewal first and a modification second; combining them on one form delays both. The most common mistake is checking New for a facility that simply changed ownership, which triggers a full effluent review instead of a quick transfer. A misconception is that “modification” covers any change; minor administrative changes use a separate Notice of Change form.
Section B, Box 7: Receiving Water and Outfall Description
Identify the named water body that receives your discharge and the outfall number. Use the name on the USGS quad map and IEPA’s Integrated Water Quality Report.
For example, Riverbend Brewing writes Outfall 001 — Sangamon River, mile 122.4. A village discharging to a tributary writes the named creek, not the larger river downstream.
The edge case is intermittent streams; list the named ditch and note “intermittent” in the comments. The common mistake is naming the larger river when discharge actually enters a tributary first, which causes wrong water-quality standards to be applied. A misconception is that all Illinois waters are General Use; Lake Michigan basin waters fall under stricter 35 Ill. Adm. Code 302 Subpart E standards.
Section B, Box 8: Design Average and Maximum Flow
Enter the design average flow in million gallons per day (MGD) and the design maximum flow. These numbers come from your engineer’s design report.
For example, a 0.5 MGD plant writes 0.500 / 1.250. Riverbend Brewing writes 0.085 / 0.170.
The edge case is seasonal facilities such as canneries; list the peak-month average and note the season. The most common mistake is reporting actual flow instead of design flow, which sets effluent limits at the wrong scale. A misconception is that exceeding design flow is a paperwork issue; it is a permit violation under 35 Ill. Adm. Code 309.141 and can trigger enforcement.
Section B, Box 9: Treatment Process Description
Describe each unit in the order wastewater flows through it: screening, primary clarifier, aeration basin, secondary clarifier, disinfection, post-aeration, and so on. Attach a process flow diagram and reference it here.
For example, Mahomet Sanitary District writes Bar screen → grit chamber → oxidation ditch → secondary clarifier → UV disinfection → post-aeration → Outfall 001.
The edge case is membrane bioreactor (MBR) plants; list the membrane separately because IEPA tracks MBR performance differently. The common mistake is omitting disinfection, which causes reviewers to assume there is none and add a special condition. A misconception is that the diagram alone is enough; the narrative description in Box 9 is what reviewers cite in the permit, so it must match the diagram exactly.
Section C, Box 10: Effluent Characteristics (Form 2C Data)
Industrial dischargers must report the concentration and mass loading of every pollutant in the 40 CFR 122 Appendix D priority pollutant list. Use a NELAP-accredited lab and attach the chain of custody.
For example, Riverbend Brewing lists BOD5 — 220 mg/L average / 380 mg/L maximum / 156 lbs/day. Each pollutant gets its own row.
The edge case is non-detect results; report the method detection limit and write “ND.” The common mistake is sampling during off-peak operation; effluent limits will be set on that low number and you will violate them later. A misconception is that one sample suffices; for many pollutants you need at least four grab samples or a composite, depending on the pollutant class.
Section C, Box 11: Antidegradation Demonstration
For new or expanded discharges, attach a written demonstration showing why the increased loading is necessary and that all reasonable alternatives were considered. The framework lives in 35 Ill. Adm. Code 302.105.
For example, a developer adding a 0.1 MGD package plant writes Antidegradation Assessment attached as Exhibit C, including alternatives analysis for connection to Mahomet Sanitary District.
The edge case is Outstanding Resource Waters, where additional loading is essentially prohibited. The common mistake is attaching a one-page memo; reviewers expect a multi-section analysis with alternatives, costs, and social/economic justification. A misconception is that antidegradation only applies to pristine waters; it applies to every water of the state at varying levels of scrutiny.
Section D, Box 12: Sludge / Biosolids Management
Describe how you handle, store, and dispose of biosolids. Reference 35 Ill. Adm. Code Part 391 and the federal 40 CFR Part 503 standards.
For example, Mahomet Sanitary District writes Aerobically digested biosolids land-applied on permitted Site IL-12345 under separate sludge permit.
The edge case is haul-off to another POTW; list the receiving facility’s NPDES number. The common mistake is writing “landfill” without the landfill name and IEPA permit number, which forces a follow-up letter. A misconception is that small plants are exempt from biosolids reporting; they are not — every plant that produces sludge must describe management.
Section E, Box 13: Certification and Signature
The certification statement at the bottom must be signed by a “responsible corporate officer” as defined in 40 CFR 122.22. For a corporation that is a president, vice-president, secretary, treasurer, or a manager of a facility employing more than 250 people or generating more than $25 million in sales. For a municipality it is the mayor, village president, or chief executive.
For example, Sarah Tanaka, President, Riverbend Brewing Holdings, LLC signs and dates the form. Print name, title, signature, and date all get filled in.
The edge case is consultant-prepared applications; the consultant cannot sign — only the responsible official can. The common mistake is letting the engineer sign in lieu of the owner, which voids the certification and forces a re-file. A misconception is that an electronic typed name is enough; IEPA requires a wet signature on paper filings or a CROMERR-compliant electronic signature on digital filings.

How to File the Completed Form
Illinois EPA accepts wastewater permit applications through four channels, and each has its own address, fee, payment method, processing time, and proof-of-filing.
- Mail. Send the original and one copy to Illinois EPA, Bureau of Water — Permit Section, 1021 North Grand Avenue East, P.O. Box 19276, Springfield, IL 62794-9276. Pay by check made out to the Illinois Environmental Protection Agency. Average review time runs 180–365 days. Keep the certified mail receipt as your filing proof.
- In Person. Deliver to the same Springfield address Monday through Friday, 8:30 a.m. to 4:30 p.m. The receptionist will date-stamp your copy as proof of filing.
- Email / Secure Portal. Submit PDF copies through the IEPA permit electronic submission inbox. Pay the fee by ACH using the agency invoice that follows. The system returns an automated confirmation email; save it.
- NetDMR (for renewals tied to monitoring data). Use NetDMR for the discharge monitoring reports that ride alongside many renewals. The system stamps each filing with a CDX confirmation number.
Fees are set by 415 ILCS 5/12.5 and range from $1,000 for small construction permits to $50,000+ for large industrial NPDES permits, depending on flow and category. Confirm the current fee on the IEPA fee schedule page before you write the check.
What Happens After You File
Once IEPA logs your application, a permit reviewer in the Bureau of Water assigns a docket number and conducts a 30-day administrative completeness check. If anything is missing you receive a Notice of Deficiency with a 30-day cure window under 35 Ill. Adm. Code 309.108.
After completeness, technical review begins: effluent limits are calculated using the Illinois Water Quality Standards, reasonable potential analysis runs against each pollutant, and special conditions are drafted. The agency then publishes a draft permit for a 30-day public comment period and, when requested, holds a public hearing.
After comments close, IEPA issues the final permit, typically valid for five years. You may appeal conditions to the Illinois Pollution Control Board within 35 days under 415 ILCS 5/40.
Mistakes to Avoid When Filling Out the Form
- Using a DBA in Box 1. The permit issues to a non-existent entity and offers no legal protection.
- P.O. Box in the physical-location field. Triggers an automatic Notice of Deficiency.
- Degrees-minutes-seconds in the lat/long box. Misroutes the discharge point into the wrong watershed.
- Reporting actual flow instead of design flow. Sets effluent limits too tight, guaranteeing future violations.
- Generic SIC code 9999. Forces manual review and adds 30+ days to processing.
- Skipping the antidegradation demonstration. Application is returned as incomplete on day one.
- Letting the consulting engineer sign Box 13. Voids the certification under 40 CFR 122.22.
- Omitting the P.E. seal on construction plans. WPC-PS-2 is rejected on intake.
- Wrong receiving-water name. Wrong water-quality standards are applied, leading to wrong effluent limits.
- Filing fewer than 180 days before expiration. Coverage gaps create unauthorized discharge violations.
- Missing biosolids description. Triggers a follow-up letter and a new sludge permit cycle.
- Submitting without the filing fee. The application is held — not reviewed — until payment lands.
Do’s and Don’ts
- ✅ Do confirm the form revision date matches the current Bureau of Water posting; old versions are rejected on intake.
- ✅ Do label every attachment “Exhibit A,” “Exhibit B,” and so on, because reviewers cite exhibits in the permit.
- ✅ Do keep a complete copy of everything you submit; you will need it during the public comment phase.
- ✅ Do call (217) 782-0610 with field-level questions before filing; staff guidance saves weeks.
- ✅ Do file at least 180 days before expiration so administrative continuance under 35 Ill. Adm. Code 309.104 protects you.
- ✅ Do use a NELAP-accredited lab for every effluent sample, because non-accredited data is rejected.
- ❌ Don’t sign the certification if you are not a “responsible corporate officer”; the certification is void.
- ❌ Don’t estimate coordinates from Google Maps without confirming with USGS data; estimation errors compound.
- ❌ Don’t combine renewal and modification on a single form; file them sequentially.
- ❌ Don’t leave any box blank — write “N/A” so reviewers know you addressed it.
- ❌ Don’t mail the only copy of engineering plans; mail one and keep one.
- ❌ Don’t ignore the Lake Michigan basin special standards if your outfall is east of the subcontinental divide.

Key Entities You Will Interact With
The Illinois Environmental Protection Agency Bureau of Water issues the permit, the Illinois Pollution Control Board hears appeals and adopts the underlying regulations, and the U.S. EPA Region 5 retains oversight under the federal NPDES delegation. Local actors include the Metropolitan Water Reclamation District of Greater Chicago for Cook County industrial users, the Illinois Department of Natural Resources for endangered-species consultations, and county health departments for private treatment systems below the IEPA threshold.
FAQs
Do I need an NPDES permit if I discharge only to a sewer and not to a stream?
No. Direct sewer dischargers fall under the receiving POTW’s pretreatment program, not NPDES. You may still need a local industrial user permit from the POTW.
Can I use a typed signature on the certification?
No. Paper filings need a wet signature, and electronic filings need a CROMERR-compliant signature. A typed name alone voids the certification.
Do I write decimal degrees or degrees-minutes-seconds in Box 4?
Yes, decimal degrees only, to four places, WGS84 datum. DMS entries are rejected and force a refile.
Is the SIC code optional now that NAICS exists?
No. IEPA still requires both because federal effluent guidelines under 40 CFR Subchapter N are organized by SIC.
How early should I file my renewal?
Yes, file at least 180 days before expiration so administrative continuance applies under 35 Ill. Adm. Code 309.104.
Can my consulting engineer sign Box 13 for me?
No. Only a “responsible corporate officer” or municipal chief executive may sign under 40 CFR 122.22.
Do I need a Construction Permit if I am only replacing a pump?
No, in-kind replacement of a single pump is usually exempt, but any change in capacity or process triggers a new WPC-PS-2.
Is one effluent sample enough for Form 2C?
No. Most pollutant categories need at least four grab samples or a 24-hour composite from a NELAP-accredited lab.
Are Lake Michigan dischargers held to different standards?
Yes. Lake Michigan basin waters fall under stricter 35 Ill. Adm. Code 302 Subpart E standards, including bioaccumulative chemical limits.
Do I need to write “SAME” if my owner and operator are identical?
Yes, write “SAME AS BOX 1” rather than leaving Box 2 blank, because blank fields are read as incomplete.
Can I appeal effluent limits I think are too strict?
Yes, file with the Illinois Pollution Control Board within 35 days of permit issuance under 415 ILCS 5/40.
Is there a fee waiver for small municipalities?
No, but reduced fees apply to small POTWs under 415 ILCS 5/12.5; confirm the current tier with the Bureau of Water.
Do I list the named tributary or the larger river in Box 7?
Yes, list the named tributary that first receives your discharge; listing the larger downstream river causes wrong water-quality standards to apply.
Is antidegradation analysis required for renewals with no changes?
No, an unchanged renewal does not need a fresh antidegradation demonstration, but any expansion or new pollutant does.
