The MassDEP NPDES Construction Stormwater permit is the coverage a builder must obtain before disturbing one or more acres of land in Massachusetts, and in this state it runs through two linked filings: the federal EPA 2022 Construction General Permit Notice of Intent (NOI), filed on EPA Form 3510-9 (NPDES Form Date 02/22), plus a MassDEP WM15 application when the site sits near Outstanding Resource Waters. The U.S. EPA, not MassDEP, is the NPDES permitting authority in Massachusetts, so the NOI is the heart of your permit, while MassDEP layers a state review on top for sensitive waters.
This guide treats the EPA NOI as the primary form because that is the document that grants your right to discharge, and it walks through the MassDEP WM15 step as the state companion filing. Federal law bars stormwater discharges from construction activity to waters of the U.S. without permit coverage, and EPA can seek civil penalties of up to roughly $66,000 per day for each violation, so a missed or sloppy NOI carries real cost. Coverage is not instant, either; after you certify the NOI, a 14-day waiting period runs before your permit becomes active.
Here is what you will learn:
- 📋 Who must file, which form applies, and the revision date to confirm before you start
- 🗂️ Every document and number to gather before you open the NOI in the EPA NeT system
- ✍️ A line-by-line walkthrough of all ten sections of EPA Form 3510-9 with real sample entries
- 🏗️ Three full filled-out scenarios for the most common Massachusetts project types
- ⚠️ The field-level mistakes that get an NOI rejected and how to dodge each one
What the Form Is and Who Must File It
The NOI is your formal request to discharge construction stormwater under the 2022 Construction General Permit, and submitting it certifies that you meet the permit’s eligibility rules in Part 1.1. The form is EPA Form 3510-9, carrying NPDES Form Date 02/22, which replaced the 02/17 version, so confirm you are using the 2022 edition before you file. In Massachusetts the companion state document is the WM15 Notice of Intent, which MassDEP requires only when your site discharges to or sits near Outstanding Resource Waters under 314 CMR 4.06.
You must file an NOI if you operate a construction site that disturbs one or more acres, or a smaller site that is part of a larger common plan of development or sale reaching a cumulative acre, with a stormwater pathway to a water of the U.S. The Clean Water Act (33 U.S.C. 1251 et seq.) and the federal rule at 40 CFR 122.26 set this trigger. “Operator” means anyone with operational control over plans and specifications, or with day-to-day control of activities needed to comply with the permit.
The plain-English version: if you control the design or run the dirt work on a Massachusetts site of an acre or more, you file. Ignoring this rule is treated as discharging without a permit, which is the most serious violation in the program and the one EPA enforces most aggressively. A common misconception is that hiring a contractor shifts the duty away from the owner; in practice both the owner and the contractor can be “operators,” and each may need its own NOI.
Before You Start: Documents and Information You Need
Gather everything below before you open the NOI, because the NeT system will not let you certify an incomplete form, and a half-finished draft can stall your 14-day clock. The single biggest gating item is the SWPPP, which must already exist when you file.
- A completed SWPPP. Part 7 of the CGP requires the Stormwater Pollution Prevention Plan to be prepared before you file; without it you cannot honestly answer Section VII, and a “No” there blocks coverage.
- Master permit number from Appendix B. Massachusetts has its own master permit number in Appendix B of the CGP; the wrong number routes your NOI to the wrong region.
- Operator legal name and mailing address. This must be the exact legal entity name, because EPA ties enforcement and correspondence to it.
- Site latitude and longitude to four decimals. EPA wants the approximate center of the site (midpoint for linear projects), and a bad coordinate can misidentify your receiving water.
- Receiving water names and impairment status. Use EPA’s Discharge Mapping Tool and the Massachusetts 303(d) list so you can name each receiving water and list any impairment pollutants.
- Estimated start and completion dates plus acreage. Acreage is reported to the nearest quarter acre, and dates use MM/DD/YYYY.
- CDX account for the certifier. The person who signs must have his or her own CDX/NeT account tied to the email listed on the NOI, or the certification step fails.
- ESA eligibility documentation. You need your Appendix D endangered species criterion selection and supporting proof, since EPA treats a missing ESA worksheet as an incomplete NOI.
- ORW determination and $500 fee (if applicable). If MassMapper shows your site near an Outstanding Resource Water, you also need the WM15 package and a $500 fee, with municipal projects exempt.
Where to Get the Form and How to Access It
You almost never use a paper NOI in Massachusetts; you file electronically through EPA’s NPDES eReporting Tool (NeT) for the CGP, reached through the EPA Central Data Exchange. Part 1.4.1 of the CGP makes electronic filing the default, and the paper EPA Form 3510-9 is allowed only if your Regional Office grants you a reporting waiver. You can read the actual fields on that PDF even if you plan to file online, which is the smart way to prepare your answers in advance.
To reach the NOI, you first register at cdx.epa.gov and choose a role. A Signatory can prepare, sign, and certify and can manage other users, while a Preparer can only view and edit and cannot certify. After registering, you request the program service “NeT – NPDES Stormwater Construction General Permit,” and once approved you launch the CGP module from your MyCDX home page.
The plain-English version: NeT is an online wizard that mirrors the ten sections of the paper form. The consequence of skipping CDX setup for the certifier is the most common delay in the whole process, because the form cannot be certified until that person’s account is active and linked to the right email. A frequent misconception is that the preparer can sign for the boss; the system blocks this, since only a registered Signatory can certify.
Step-by-Step: How to Fill Out EPA Form 3510-9 Line by Line
The NOI has ten sections, and each one below gets its own walkthrough. File the answers in uppercase, place one space between words, and keep dates in MM/DD/YYYY format, because the official instructions ask for exactly this.
Section I: Approval to Use Paper NOI Form
This section asks one question: have you been granted a waiver from electronic reporting by the EPA Regional Office? In plain terms, EPA wants to know whether you are even allowed to use the paper version of this form. You answer by checking Yes or No, and if Yes, you check which waiver applies (under-served broadband area or computer-access limits), then write the EPA staff name and approval date.
For example, Brookline Builders LLC checks No because it is filing online through NeT, which is what nearly every Massachusetts filer does. The edge case is a rural operator in a broadband-poor ZIP code who got a written waiver; that filer checks Yes and names the EPA contact who approved it. The common mistake is checking Yes without an actual approval on file, which makes the paper filing invalid and leaves the site uncovered. A frequent misconception is that anyone may simply choose paper for convenience; you cannot, because paper requires advance Regional Office approval.
Section II: Permit Information
This section asks for the master permit number of the permit you are seeking coverage under, drawn from Appendix B of the CGP. In plain English, this is the state-specific code that tells EPA your project is in Massachusetts. You leave the “NPDES ID” line blank, since that is marked EPA Use Only, and enter only the master permit number from Appendix B.
For example, a Worcester developer enters the Massachusetts master permit number listed for Region 1 in Appendix B. The edge case is a project on tribal land or a federal facility, which can carry a different master number, so check Appendix B carefully. The common mistake is copying a neighboring state’s master number, which misroutes the NOI and delays review past your planned start date. A misconception is that the NPDES ID is something you create; it is auto-assigned by EPA after you file.
Section III: Operator Information
This section captures who you are as the legal operator, including operator name, whether you are a Federal Operator or Federal Facility, your mailing address, county, and a point of contact with phone and email. In plain English, EPA wants the exact legal entity that controls the work and a real person it can email about approval. Enter the full legal name, check No for Federal Operator unless you truly are one, and give a monitored email, because the NOI approval notice goes there.
For example, Maria Santos, owner of Santos Site Development Inc., enters the company’s legal name, a Framingham mailing address, Middlesex county, and lists herself as the point of contact with a working cell and email. If a consultant prepared the form, the NOI Preparer block on page 2 is also filled with that consultant’s name, organization, phone, and email. The common mistake is entering a “doing business as” trade name instead of the registered legal entity, which can break the link between the permit and the responsible party during enforcement. A misconception is that the point of contact must be the owner; it can be any reliable person, but the email must be one someone actually checks.
Section IV: Project/Site Information
This is the largest data section, asking for the project name and address, latitude and longitude to four decimal places, Indian country status, start and completion dates, acreage disturbed, construction type, prior agricultural use, whether earth-disturbing work has started, prior permit history, other operators, demolition of pre-1980 structures, and dewatering. In plain English, this paints a full picture of what you are building, where, and how big. Enter coordinates from the approximate center of the site (midpoint for linear projects), report acreage to the nearest quarter acre, and check every construction type that applies.
For example, Santos Site Development enters MAPLE RIDGE COMMONS, a Framingham street address, latitude 42.2793 N and longitude 71.4162 W from GPS using datum NAD 83, an estimated start of 07/15/2026, completion of 11/30/2027, and 4.25 acres disturbed, checking Multi-Family Residential. The edge case is a road project with no street address, where you instead describe the location, such as Intersection of Route 9 and Edgell Road. The common mistake is rounding acreage down to dodge the one-acre trigger, which is treated as filing a false NOI and can bring penalties. A misconception is that “Estimated Project Start Date” is binding; it is an estimate, but starting earth-disturbing work before coverage is active is a violation regardless of the date you wrote.
Section V: Discharge Information
This section confirms you understand the CGP only authorizes the discharges listed in Parts 1.2.1 and 1.2.2, then asks whether you discharge to an MS4, whether any waters of the U.S. lie within 50 feet of your earth disturbances, the receiving water for each point of discharge, any impairment pollutants, any completed TMDLs, and whether you discharge to a Tier 2, 2.5, or 3 water. In plain English, EPA wants to know where your dirty water ends up and how sensitive that water is. Check the confirmation Yes, then name each receiving water and flag impairments using EPA’s Discharge Mapping Tool.
For example, Maria checks that her site discharges to the Sudbury River via the town MS4, notes the river is impaired for E. coli and phosphorus with a completed bacteria TMDL, and confirms a wetland sits within 50 feet, which triggers the Part 2.2.1 buffer rule. The edge case is a site with several outfalls, where you attach a separate list and assign a Point of Discharge ID to each. The common mistake is naming the storm drain instead of the first natural water of the U.S. that receives the flow, which mis-reports your receiving water. A misconception is that discharging to an MS4 means you skip receiving-water reporting; you must still name the water the MS4 ultimately reaches.
Section VI: Chemical Treatment Information
This section asks whether you will use polymers, flocculants, or other treatment chemicals, and specifically whether you will use cationic treatment chemicals such as C-PAM, PolyDADMAC, or chitosan. In plain English, EPA is checking whether you plan to dose stormwater with chemicals that can themselves harm aquatic life. Check Yes or No, and if you use cationic chemicals, confirm you received advance written authorization from your Regional Office and attach the letter.
For example, a large grading job that uses passive anionic polyacrylamide socks checks Yes to treatment chemicals but No to cationic, and lists the product. The edge case is a turbidity-heavy site that wants C-PAM; that operator is ineligible until EPA Region 1 authorizes it in advance with documented controls. The common mistake is starting cationic chemical use before approval, which voids your eligibility for the entire permit. A misconception is that all polymers need pre-approval; only cationic chemicals carry the advance-authorization trap.
Section VII: SWPPP and Personnel Training Information
This section asks whether the SWPPP was prepared in advance of filing, confirms your personnel will meet the Part 6 training requirements, and collects the SWPPP location and contact information. In plain English, EPA wants proof your written plan already exists and that someone qualified owns it. Check Yes to both confirmations and list the SWPPP contact’s name, title, phone, and email plus where the plan is kept.
For example, Maria checks Yes, names her erosion-control consultant David Chen as the SWPPP contact, and lists the site trailer address where the plan is stored. The edge case is a multi-operator site where each operator keeps its own SWPPP section; you still list a single point of contact for your portion. The common mistake is checking Yes when the SWPPP is only half-drafted, which is a false certification because Part 7 demands a complete plan before filing. A misconception is that the SWPPP gets uploaded with the NOI; it does not, but it must exist and be available on request.
Section VIII: Endangered Species Protection
This section requires you to confirm you completed the Appendix D ESA worksheet and attached all supporting documents for your chosen eligibility criterion. In plain English, EPA must verify your project will not harm federally listed threatened or endangered species or critical habitat before it grants coverage. In NeT you work through the Appendix D criteria on screen and check Yes to confirm the worksheet and documentation are included.
For example, Maria selects Criterion A after confirming no listed species or critical habitat occur in her project’s action area, and attaches her supporting screen results. The edge case is a site near habitat for a listed species, which can force Criterion C or D, formal coordination, and added controls before EPA authorizes the NOI. The common mistake is leaving the ESA worksheet blank, which makes the entire NOI incomplete and stops the 14-day clock from ever starting. A misconception is that endangered species rules only apply out West; New England has listed species, so every Massachusetts filer must complete this section.
Section IX: Historic Preservation
This section walks through the Appendix E screening process, asking whether you will install stormwater controls needing subsurface earth disturbance, whether prior surveys ruled out historic properties, and whether you reached a “no effect” finding or coordinated with the SHPO or THPO. In plain English, EPA wants to be sure digging in for your erosion controls will not damage historic or cultural resources. Answer each step’s Yes/No exactly as Appendix E directs, and describe any SHPO or THPO response.
For example, Maria checks Yes that her infiltration basin needs subsurface disturbance, then checks Yes that a prior site survey already showed no historic properties exist, which ends the inquiry. The edge case is an unsurveyed parcel near a historic district, where you must contact the Massachusetts Historical Commission (the state SHPO) and wait up to 15 calendar days for a response. The common mistake is treating “no street address” or “raw land” as automatically clear of historic concern, which skips a required step. A misconception is that only buildings count; buried archaeological sites are historic properties too.
Section X: Certification Information
This final section is the signature, where the authorized person certifies under penalty of law that the information is true, accurate, and complete, entering name, title, signature, date, and email. In plain English, this is where a legally authorized official puts their name on the line. The signer must be the right type of official: a responsible corporate officer for a corporation, a general partner or proprietor for a partnership or sole proprietorship, or a principal executive or ranking elected official for a public agency.
For example, Maria Santos, as president of Santos Site Development Inc., certifies the NOI herself in NeT after her consultant submits it to her for review. The edge case is a town project, where the certifier must be a principal executive officer or ranking elected official, not a staff engineer. The common mistake is having the consultant or project manager sign without delegated authority, which makes the NOI legally invalid. A misconception is that an electronic certification is less binding than ink; the penalties for false certification, including fines and possible imprisonment, apply equally.
The MassDEP WM15 Companion Step
If your Massachusetts site discharges to or sits near an Outstanding Resource Water, the EPA NOI alone is not enough; you must also file the WM15 NPDES General Permit Notice of Intent with MassDEP for state authorization. To check whether you are near an ORW, open MassMapper, select Physical Resources, then the Outstanding Resource Waters layer. If your site is near or discharges to an ORW, you submit your CGP SWPPP for MassDEP review along with the WM15 and a $500 application fee, which municipal projects do not pay.
The plain-English version: MassDEP wants a second look at your erosion plan when your runoff could reach the state’s most protected waters. The consequence of skipping the WM15 when an ORW is involved is that you lack the required state authorization even if your EPA NOI is active, leaving the project out of compliance. As a real example, a private developer building near a Class A public water supply reservoir files the WM15, pays $500, and emails stormwater.dep@mass.gov with questions, while a town DPW doing the same work files the WM15 but pays no fee. A common misconception is that every Massachusetts construction project needs a WM15; it is required only for ORW-related sites.
Three Filled-Out Examples Using Real Scenarios
Below are three of the most common Massachusetts construction stormwater filings, each following one named operator through the NOI. Use them as templates for the type of answers EPA expects in NeT.

How to File the Completed Form
Massachusetts filers have one primary channel and one backup, and you should keep proof of filing for both your EPA and state submissions. The standard route is electronic, with paper reserved for waiver holders.
- EPA NeT (electronic, standard). File at the CGP NeT system through cdx.epa.gov; there is no EPA filing fee, the preparer submits to the certifier, and the certifier clicks “Submit to EPA.” Download the NOI PDF as your proof, and watch your status change to “Certified,” then “Active” after 14 days.
- EPA paper (waiver only). Mail EPA Form 3510-9 with an original ink signature to the Stormwater Notice Processing Center, Mail Code 4203M, ATTN: 2022 CGP, U.S. EPA, 1200 Pennsylvania Avenue, NW, Washington, DC 20460; keep a copy and proof of mailing.
- MassDEP WM15 (ORW sites only). Follow the WM15 instructions, submit the SWPPP for review, and pay the $500 fee (municipal projects exempt); keep your payment receipt and submission confirmation.
For payment, EPA charges nothing for the NOI, so the only fee in the whole process is the MassDEP $500 ORW review fee, payable per MassDEP’s instructions. Processing time on the EPA side is the fixed 14-day waiting period after certification, while MassDEP review timing varies with the complexity of the SWPPP. Always save the system-generated confirmation, because that timestamp is what proves you filed before breaking ground.
What Happens After You File
After you certify the NOI in NeT, EPA assigns your NPDES ID (your tracking number) and begins the 14-day waiting period, during which you may not start earth-disturbing work. Once those 14 days pass without EPA objection, your status shows “Active,” and your authorization to discharge under the CGP begins. You should download and store the active NOI and your NPDES ID, since inspectors and lenders routinely ask for them.
During this window EPA may contact you if your ESA or historic-preservation answers need additional controls, and responding promptly keeps your timeline on track. The plain-English version: filing is not the finish line, it is the start of a compliance relationship that lasts the whole project. The consequence of treating “Active” as the end is missing your ongoing duties under the permit. You still must implement the SWPPP, run inspections on the Part 6 schedule, keep records, and file a Notice of Termination on EPA Form 3510-10 when the site is finally stabilized.
Mistakes to Avoid When Filling Out the Form
Each error below has sunk real NOIs, and each carries a direct consequence for your coverage.
- Starting earth-disturbing work before coverage is Active. You are discharging without a permit, the most serious violation in the program.
- Filing the NOI before the SWPPP exists. Section VII becomes a false certification, voiding eligibility.
- Rounding acreage below one acre to avoid filing. EPA treats it as a false statement and can pursue penalties.
- Naming the storm drain instead of the natural receiving water. Your discharge information is wrong and may misroute review.
- Leaving the Appendix D ESA worksheet blank. The NOI is incomplete, so the 14-day clock never starts.
- Skipping the historic-preservation steps on raw land. You miss a required Appendix E step and risk an invalid filing.
- Using cationic treatment chemicals without advance approval. You lose eligibility under the entire permit.
- Having an unauthorized person certify. The NOI is legally invalid and confers no coverage.
- Using the wrong master permit number from Appendix B. The NOI is misrouted and delayed past your start date.
- Forgetting the certifier’s separate CDX account. Certification cannot complete, stalling the whole filing.
- Ignoring the WM15 when the site is near an ORW. You lack required MassDEP authorization even with an active NOI.
- Letting the contact email go unmonitored. You miss EPA’s approval notice and any request for added controls.
Do’s and Don’ts
- Do confirm you are on EPA Form 3510-9 (Form Date 02/22) before entering any data, because the wrong version asks the wrong questions.
- Do prepare the full SWPPP first, since the NOI certifies it already exists.
- Do pull coordinates from the site’s center and verify them on a map, because a bad point names the wrong water.
- Do set up the certifier’s CDX account early, because certification depends on it.
- Do check MassMapper for ORW status, because that determines whether a WM15 is required.
- Do save every confirmation and your NPDES ID, because they are your proof of timely filing.
- Don’t break ground during the 14-day waiting period, because coverage is not yet Active.
- Don’t let a preparer try to sign, because only a registered Signatory can certify.
- Don’t guess at impairment or TMDL data, because EPA’s mapping tools give the correct answer.
- Don’t use trade names in the operator field, because enforcement tracks the legal entity.
- Don’t assume endangered species rules skip New England, because Massachusetts has listed species.
- Don’t skip the $500 WM15 fee on a private ORW project, because MassDEP will not authorize without it.
Pros and Cons of Filing on Your Own vs. With Help
Many small operators file the NOI themselves, while larger or sensitive projects hire an environmental consultant, and each path has trade-offs.
| Filing on Your Own | Filing With a Consultant |
|---|---|
| Pro: No consultant fee, since the NOI itself is free to file | Pro: Expert handles the tricky ESA and historic screening |
| Pro: You learn the permit, which helps with later inspections | Pro: Lower risk of a rejected or incomplete NOI |
| Pro: Faster for a simple, non-impaired, non-ORW site | Pro: Consultant can also build the required SWPPP |
| Pro: Full control over your own timeline | Pro: Saves your time on a complex multi-operator site |
| Pro: Direct familiarity with your own site data | Pro: Useful when discharging to impaired or Tier 2/3 waters |
| Con: Easy to err on ESA, TMDL, or buffer questions | Con: Costs money on top of the SWPPP work |
| Con: You shoulder all certification liability | Con: You still must certify and remain legally responsible |
| Con: SWPPP preparation is time-consuming to self-build | Con: Less hands-on knowledge of the permit for later phases |
FAQs
Do I file the NOI before or after I start construction?
Yes, before. You must have active coverage prior to any earth-disturbing work, and the 14-day waiting period after certification means you should file well ahead of your start date.
Does EPA charge a fee for the construction stormwater NOI?
No. The EPA NOI is free; the only fee in Massachusetts is the $500 MassDEP WM15 review fee, and only for non-municipal sites near Outstanding Resource Waters.
Is MassDEP or EPA the permitting authority in Massachusetts?
No, MassDEP is not the NPDES authority here. EPA Region 1 issues the construction permit, while MassDEP adds a state review through the WM15 for ORW-related sites.
Do I need a WM15 for every Massachusetts construction project?
No. The WM15 is required only when your site discharges to or is near an Outstanding Resource Water under 314 CMR 4.06.
Do I enter my company’s trade name or legal name in the Operator field?
No trade names. Section III requires the exact legal entity name, because EPA ties permit coordination and enforcement to that registered name.
Do I list the storm drain as my receiving water in Section V?
No. You name the first natural water of the U.S. that ultimately receives the flow, even when discharge first enters an MS4 storm drain.
Does my SWPPP get uploaded with the NOI?
No. The SWPPP must exist before filing and be available on request, but you do not attach it to the EPA NOI itself.
Do I round my acreage down if I’m just over one acre?
No. Report acreage to the nearest quarter acre honestly; understating it to dodge the trigger is treated as a false NOI.
Can my consultant or project manager certify the NOI for me?
No, unless they hold proper authority. Only a responsible corporate officer, partner, proprietor, or ranking public official may certify.
Do I need a separate CDX account for the person who signs?
Yes. The certifier must register their own CDX account tied to the email on the NOI, or the certification step will not work.
Does coverage start the moment I hit submit?
No. After certification, a 14-day waiting period runs, and only then does your status become Active and your discharge authorized.
Do I still file with EPA if I’m only disturbing part of a larger development?
Yes, if the larger common plan reaches one acre. Smaller parcels within a one-acre-plus common plan of development or sale still need coverage.
