Responsible Officials, Authorized Representatives, and the Signatures Behind Your NOI, No Exposure Certification, and DMRs
Every piece of stormwater paperwork your facility sends to the Pennsylvania Department of Environmental Protection (DEP) needs a signature. That includes the Notice of Intent (NOI) that gets your site covered under PAG-03, Pennsylvania's general permit for industrial stormwater, a No Exposure Certification, the Discharge Monitoring Reports (DMRs) that carry your sampling results, and the other reports your permit calls for. The rules don't let just anyone sign, though. They name specific kinds of people, and a signature from someone outside that list can get a document sent back or leave you with a report that doesn't count.
The short answer is that applications, including your NOI, have to be signed by a responsible official, which is a corporate officer, a general partner, a proprietor, or a top public official depending on how your organization is set up. Reports like DMRs can also be signed by a duly authorized representative, but only after a responsible official has authorized that person in writing and sent the authorization to DEP. This article walks through who qualifies as a responsible official, when a duly authorized representative can sign in their place, what the signer is promising when they sign, and how to set up your paperwork so it holds up. If you'd rather talk through your own situation, you can reach out to RMA at any time.

TL;DR
In Pennsylvania, an NPDES stormwater application, including your NOI, has to be signed by a responsible official: a corporate officer or qualifying facility manager for a corporation, a general partner or the proprietor for a partnership or sole proprietorship, or a principal executive officer or ranking elected official for a public agency. Reports like DMRs can also be signed by a duly authorized representative, but only if a responsible official has named that person or position in writing and sent the authorization to DEP. Whoever signs is certifying under penalty of law that the information is true, accurate, and complete, so a signature from the wrong person can mean rejected paperwork, and a careless signature from the right person can mean real legal exposure.
What Is a Responsible Official Under PA DEP Stormwater Rules?
Pennsylvania doesn't write its own signature rule for NPDES stormwater permits. Instead, 25 Pa. Code § 92a.22 adopts the federal signatory rule, 40 CFR § 122.22, by reference. (NPDES stands for National Pollutant Discharge Elimination System, the permit program that covers stormwater leaving industrial sites.) That means the federal text controls who can sign applications and reports for PAG-03 and individual NPDES permits.
The rule talks about a "responsible corporate officer" for corporations and names different signers for other kinds of businesses. "Responsible official" is the shorthand most people use for whoever the rule allows to sign, and it's how we'll use it here. Applications can only be signed by the people the rule names. Reports and information DEP asks you for can be signed by those same people, or by someone they've authorized in writing.
Who Qualifies as a Responsible Official for Stormwater Permit Signatures?
Who counts depends on how your business is organized. The table below summarizes what 40 CFR § 122.22(a) says for each type of entity.
| Type of Entity |
Who Can Sign an Application |
| Corporation |
A responsible corporate officer: a president, secretary, treasurer, or vice president in charge of a principal business function, or anyone who performs similar policy or decision-making functions. A manager of one or more manufacturing, production, or operating facilities can also qualify if they meet the conditions described below. |
| Partnership |
A general partner |
| Sole proprietorship |
The proprietor |
| Municipality, state, federal, or other public agency |
A principal executive officer or the ranking elected official |
The facility manager route is the one that trips people up, because plant and site managers often assume it applies to them automatically. It doesn't. The manager has to be authorized to make the management decisions that govern the facility, including the duty, explicit or implied, of recommending major capital investments and directing the measures that keep the facility in long-term compliance. The manager also has to be able to make sure complete and accurate information gets gathered for the application, and the company has to have assigned or delegated signing authority to that manager under its own procedures. A site manager who runs daily operations but has no say over capital spending or compliance decisions probably doesn't meet that test.
EPA's note in the rule says it presumes corporate officers have the authority to sign unless the corporation has told the permitting agency otherwise. Older guidance, and some other states' rules, still cite an employee-count and sales threshold for facility managers. The current federal text doesn't include one, so don't rely on an old checklist that mentions it.
The rule doesn't mention LLCs. If an LLC owns your facility, match your signer to the officer or partner categories as closely as your structure allows, such as a managing member with real decision-making authority, and confirm the choice with DEP before the NOI goes in. DEP's current forms and instructions control how it treats a given company structure.
Which PA DEP Stormwater Documents Need a Responsible Official's Signature?
The split between applications and reports decides who can sign what. An application has to carry a responsible official's signature. A report required by your permit, or information DEP requests from you, can be signed by a responsible official or by a duly authorized representative, which we'll cover in the next section.
| Document |
Who Can Sign |
| NOI for PAG-03 coverage, and renewal applications for coverage |
Responsible official only |
| Individual NPDES permit application |
Responsible official only |
| No Exposure Certification |
The form carries its own certification, and it works like an application, so plan on a responsible official signing it |
| DMRs submitted through eDMR |
Responsible official or duly authorized representative |
| Other reports your permit requires, and information DEP asks you to submit |
Responsible official or duly authorized representative |
Forms and report types change over time, and your permit and DEP's current forms control. The pattern above is what the federal rule sets, and your paperwork should follow it unless a current DEP form says something stricter. If you're still sorting out which path fits your site, our guide to general, individual, and No Exposure coverage lays out the differences, and what No Exposure means under an NPDES stormwater permit covers what you'd be certifying.
How Does a Duly Authorized Representative Sign Stormwater Reports?
A responsible official can hand off the signing of reports without handing off the legal responsibility for them, and the rule gives a specific recipe for doing it. A person is a duly authorized representative only if three things are true. First, the authorization is in writing and comes from a responsible official. Second, the authorization names either an individual or a position that has responsibility for the overall operation of the regulated facility, such as plant manager or superintendent, or an individual or position with overall responsibility for environmental matters for the company. Third, the written authorization is submitted to DEP.
Naming a position instead of a person is usually the smarter choice. The rule says a duly authorized representative can be a named individual or whoever occupies a named position, so an authorization for "Plant Manager" keeps working when the person in that seat changes.
Can a Consultant or Outside Contractor Sign Your Stormwater Reports?
The authorization has to name someone with responsibility for the overall operation of the facility or for environmental matters for the company, and an outside consultant or lab doesn't sit in either seat. A consultant can prepare a DMR for you, but the signature and certification belong to someone at your company. If anyone suggests a third party sign as your authorized representative, check with DEP first.
What Happens When the Authorized Person Changes?
If an authorization is no longer accurate because a different individual or position now has the responsibility, the rule requires a new authorization to be submitted to DEP before or along with any report that person will sign. Turnover is where facilities slip. The named plant manager retires, the new one starts signing DMRs, and nobody sends DEP an updated authorization.
What Are You Certifying When You Sign a PA DEP Stormwater Document?
Whoever signs under the rule has to make a certification, and the federal text spells it out. In plain terms, the signer is stating, under penalty of law, that the document and all its attachments were prepared under their direction or supervision, using a system designed so qualified people gather and evaluate the information. Based on their own inquiry of the people who manage that system or who gathered the information, they're saying the contents are true, accurate, and complete. The statement also acknowledges that there are significant penalties for submitting false information, including fines and imprisonment for knowing violations.
That's a lot to attach to a signature line, and it's why the signer shouldn't be someone who only sees the document at the moment it's signed. On a DMR, that means knowing who collected the samples, which lab ran them, and whether the numbers on the report match the lab's results. Even a DMR reporting that no discharge occurred carries the same certification, and our article on reporting no discharge on a DMR explains when that's an honest answer.
If you learn that something you signed was wrong, an environmental attorney is the right person to advise you on correcting a signed statement. We can help with the technical side, but we don't give legal advice.
How Does eDMR Electronic Signing Work for PAG-03 Stormwater Reports?
PAG-03 permittees submit DMRs through DEP's electronic DMR system, known as eDMR. Electronic signing doesn't loosen any of the rules above. The federal rule says that anyone providing an electronic signature for these documents has to meet all the signatory requirements of the section, and the submission has to meet the federal electronic reporting rules in 40 CFR Part 3 and 40 CFR Part 127.
In practice, eDMR ties each submission to a registered user's secure login, and that submission works as the user's electronic signature. A login belongs to one person, and that person has to be someone who's allowed to sign. Sharing a login with a coworker, an assistant, or a consultant defeats the whole signature structure, so everyone who submits reports needs to be a responsible official or a properly authorized representative with their own access. DEP's registration steps and system details change from time to time, so check its current eDMR page before you set anyone up. Our guide to Pennsylvania eDMR reporting walks through the system itself, and our overview of what Discharge Monitoring Reports are covers what goes into one.
What Happens If the Wrong Person Signs a PA DEP Stormwater Document?
How DEP handles a signature problem depends on the document and the reviewer. An NOI signed by someone who doesn't qualify as a responsible official can be returned as incomplete, which pushes back your coverage date while the facility keeps operating without it.
Reports are a different kind of problem. A DMR signed by someone who isn't a responsible official or a properly authorized representative may not count as a valid submission, which can leave a gap in your reporting record that shows up later during an inspection or a file review. Our overview of what happens during a PA DEP stormwater inspection covers the records an inspector may ask for.
The bigger risk comes from the certification itself. A document signed by the right person is still a sworn statement, and knowingly submitting false information carries criminal penalties under the rule's own language. A transposed number or a missed sample is an honest mistake and very different from knowing falsification, and the way to stay on the right side of that line is for the signer to review what they're certifying. If you're dealing with a violation, a consent order, or a possible false statement, bring in an environmental attorney.
How Do You Set Up Signature Authority for Your Stormwater Paperwork?
The setup is short, and it pays off every time someone changes jobs. Start by deciding who your responsible official is for applications. For most companies that's an officer, or a facility manager who clearly meets the conditions in the rule. That person signs the NOI, the renewal applications, and the No Exposure Certification if you use one.
Next, decide who will sign your recurring reports and write the authorization. A short letter from the responsible official that names the position or positions, such as plant manager or environmental manager, and states that those positions are authorized to sign reports and information for the facility is usually all it takes. It should be signed, dated, and submitted to DEP, as the rule requires. Keep a copy in the same file as your stormwater plan so that anyone who takes over the program can find it.
Then recheck the authorization any time your staffing changes. Promotions, retirements, a sale of the facility, or a reorganization can all make an old authorization inaccurate, and the fix is a new letter to DEP before the next report goes out. Finally, make sure the people who sign understand what they're signing. RMA's online environmental training library is one place to start, and if you're considering handling the permit paperwork yourself, our article on getting a PAG-03 permit yourself covers what that involves.
How Can RMA Help With PA DEP Stormwater Paperwork and Signatures?
If your facility is organized in a way that makes the signer unclear, such as an LLC, a company with several owners, or a site where authority has been informally passed around, we can look at your setup and help you work out who should sign what. We can also draft the authorization letter for your responsible official to review, prepare your NOI and supporting documents, and get your DMRs and other reports ready for the right person to review and sign. The certification stays with your company, which is how it should be, but you shouldn't have to figure out the paperwork structure alone.
You don't need to be a client to ask us a question about this. You can call us, send an email, or fill out the form on our website, with no pressure or obligation, or contact RMA directly. If we're not the right fit, we'll say so and point you in a better direction.
