Getting Off an Individual Stormwater Permit: When a Pennsylvania Facility Can Move Back to PAG-03 or No Exposure, and What Makes DEP Say No
If your Pennsylvania facility has an individual NPDES permit for stormwater, you've probably noticed that other facilities get a lighter-looking option. An NPDES permit is the Clean Water Act permit that covers what leaves your site in stormwater. Many industrial facilities in the state sit under PAG-03, the general permit PA DEP issues for eligible facilities, where a Notice of Intent replaces a custom application and the rules come standardized. Others hold a No Exposure Certification, which tells DEP that industrial materials and activities are protected from rain and snow, so no permit is needed. An individual permit has its own terms, its own renewal cycle, and often more paperwork, so the question comes up a lot: can we move back?
Sometimes, yes. It can work when the reasons DEP put you on an individual permit no longer apply. You may have eliminated exposure, your sampling may have run clean for a long stretch, or your operations may have changed. It also depends on DEP's evaluation and on the stream your site drains to, and nobody can promise the result ahead of time. Below we cover why facilities end up on individual permits, which of those reasons can go away, how the move to PAG-03 or No Exposure works, what evidence helps, and where people get burned by overpromising. If you'd like a second set of eyes on your situation, you can reach out to RMA.

TL;DR
A Pennsylvania facility can sometimes move from an individual NPDES permit to PAG-03 or a No Exposure Certification, but only when the reason it needed the individual permit no longer applies. Moving all industrial activity indoors or under roof, a long run of clean sampling results, a clean compliance record, and changes to operations all help. A protected receiving stream or a separate wastewater permit usually keeps a facility where it is. DEP makes the decision based on your application and your receiving water, so keep following your individual permit until DEP approves a change, and be wary of anyone who promises the outcome.
Why Does a Pennsylvania Facility End Up on an Individual NPDES Permit?
PAG-03 isn't open to every industrial facility. The permit lists discharges it doesn't authorize, and DEP denies coverage when one of them applies. A facility that doesn't fit gets an individual permit instead, which DEP writes around that one site. DEP's own guidance says a common reason a facility can't use PAG-03 is a location in a High Quality (HQ) or Exceptional Value (EV) watershed. Those are the two highest protection tiers Pennsylvania assigns to streams under Chapter 93 of 25 Pa. Code, the part of the state's rules that classifies waters and sets their designated uses. DEP can also base the tier on a stream's existing use. Stormwater discharged directly to HQ or EV waters can't be covered by PAG-03, and No Exposure isn't available there either.
HQ and EV waters are only one route to an individual permit. PAG-03's list of unauthorized discharges also covers stormwater going to impaired waters when the discharge contains pollutants that could contribute to the impairment, stormwater subject to a wasteload allocation in a Total Maximum Daily Load (TMDL), discharges from permittees with a history of failing to comply with DEP permits or orders, and discharges covered by federal effluent limitation guidelines. A facility that already holds an individual permit for non-stormwater discharges, such as process wastewater, can't use PAG-03 for its stormwater at all, because the stormwater is written into that permit. DEP can also require an individual permit when it decides one is needed to protect water quality, including for a PAG-03 permittee whose benchmark exceedances continue. If you want the three permit paths laid out in plain language, our guide to which NPDES permit you need covers them.
Pin down your own reason before anything else. The fact sheet DEP wrote for your individual permit often states why PAG-03 wasn't an option, and the answer decides whether a move is realistic at all.
Which Reasons for an Individual Permit Can Go Away?
Some reasons are about the stream or the regulated activity, and those rarely change. Others are about how you run the site, and those often can. The table sorts the common ones.
| Reason for the individual permit |
Can it go away? |
What DEP will want to see |
| Direct discharge to an HQ or EV stream |
Rarely. Neither PAG-03 nor No Exposure is available, and the stream's classification isn't yours to change. |
A change in the stream's status or in where your site discharges. |
| Individual permit for process wastewater |
Usually not while that permit stands, since your stormwater is part of it. |
The process discharge ending or being rerouted, which changes the picture. |
| Impaired stream or TMDL |
Possible if your discharge doesn't contain the pollutant behind the impairment. |
Sample results for that pollutant and a clear link between your site and the TMDL. |
| Compliance history |
Possible, with time and a clean record. |
Resolved violations, on-time reports, and no open enforcement. |
| Repeated benchmark exceedances |
Possible if you fix the cause. |
Corrective actions and a sustained run of better results. |
| Activity with its own federal effluent limits |
No. DEP's FAQ says asphalt emulsion plants, for example, need an individual permit regardless of compliance history. |
The regulated activity ending. |
| Exposed industrial materials and activities |
Yes, if you can enclose or cover all of them. |
Documentation that nothing industrial is exposed to rain or snow. |
Read your own situation against that list. If your reason sits in the top two rows, plan on staying put unless something about the stream or your wastewater changes. If it sits in the lower rows, you may have a real path. Our article on TMDLs, impaired waters, and stormwater permits helps if the receiving stream is the issue.
How Does Moving From an Individual Permit to PAG-03 Work?
The move starts with a Notice of Intent (NOI), the form (3800-PM-BCW0083b) a facility files to ask for coverage under a general permit. It goes to the DEP regional office that covers your county. For an existing facility, the package typically includes a description of your industrial activities, a site map and outfall information, a Preparedness, Prevention, and Contingency (PPC) Plan, and sampling results. A PPC Plan is the plan DEP expects you to keep for preventing and responding to spills and pollutant releases. DEP's FAQ says existing facilities provide results for the pollutants listed in their PAG-03 appendix covering the past two years, plus any pollutant causing a stream impairment. If you don't have a current PPC Plan, our comparison of SWPPPs and PPC Plans for PAG-03 explains what DEP expects.
Can You Keep Your Individual Permit While DEP Reviews the PAG-03 NOI?
Yes. PAG-03 says a facility with an individual permit that has applied for coverage may keep discharging under that individual permit while DEP reviews the NOI. You're responsible for every term of the individual permit during that time, including sampling, discharge monitoring reports, and annual reports. DEP can deny coverage after reviewing your NOI and your monitoring data, and if it does, the individual permit stays your path.
If DEP approves coverage, you'd then ask DEP to end the individual permit by filing a Notice of Termination (3800-PM-BCW0410) with the regional office that issued it. That form doesn't pause any permit requirement, and you have to keep following the individual permit until DEP approves the termination. How regional offices sequence the NOI approval and the termination can vary, so ask yours before you file.
Simpler isn't always the right word for PAG-03. It trades custom terms for standard ones, and the standard terms come with sector-specific best management practices, sampling at representative outfalls at least every six months, electronic Discharge Monitoring Reports (DMRs) through DEP's eDMR system, an annual report, and an annual fee. Two consecutive benchmark exceedances at an outfall trigger a corrective action plan, and continued exceedances can put a facility back on an individual permit. If your current permit is already light on monitoring, work out what you'd gain before you spend money on the switch. Our guides to PAG-03 requirements and sampling and eDMR reporting show what the day-to-day looks like.
Can a Facility With an Individual Permit Qualify for No Exposure?
Sometimes, and it takes more than a tidy yard. In general, all industrial materials and activities have to be stored and conducted indoors or under roof, and DEP evaluates the whole facility, not part of it. The No Exposure Certification (NEC) is only for facilities that federal rules already regulate as industrial stormwater dischargers, so it isn't available to a facility DEP made apply because of pollutants in its runoff. Direct discharges to HQ or EV streams are out as well. Your application is the NEC form (3800-PM-BCW0083e) plus the PAG-03 NOI, a topographic map, a site map, a PPC Plan if one applies, and, for existing discharges, lab results for the eight parameters listed on the NEC form. DEP's instructions also note that filing doesn't guarantee approval, and the facility has to allow DEP to inspect for no exposure.
What Counts as a Storm-Resistant Shelter for No Exposure?
DEP's FAQ describes a storm-resistant shelter as a fully roofed and walled structure, or a structure with only a top cover as long as stormwater can't flow through it and wind-blown rain or snow can't run out, which usually means a curb or berm. Tarps and similar flexible covers generally can't stand in for a permanent structure, though they can work on temporary setups like dumpsters. Tightly sealed drums and tanks, covered dumpsters in good condition, and final products that wouldn't wash away don't need a shelter. A fueling area without a roof or cover is out, vehicle wash areas have to be indoors, and using deicing salt on parking lots and walkways doesn't disqualify you on its own. Our article on what No Exposure means goes through the same ideas, and it helps to know what happens during a PA DEP stormwater inspection before DEP comes to check your setup.
Getting there often means building something, like a roof over a storage bay, an enclosure for a wash area, or a new building. Those projects can bring their own approvals, including local building and land development approvals and, depending on how much ground you disturb, Pennsylvania's construction-phase stormwater requirements under Chapter 102. We don't prepare those approvals, and your engineer or contractor will usually lead on them. What we can do is help you judge whether the finished site would meet DEP's no exposure test before you spend the money, and then handle the operational side once it's built.
What Evidence Helps Make the Case for Moving Off an Individual Permit?
DEP is deciding whether the reason for your individual permit still holds, so your job is to show that it doesn't. The strongest packages are documented, recent, and specific to the reason on your fact sheet.
| Evidence |
What it shows DEP |
| Sampling results from an accredited lab, ideally two years or more |
Your discharge quality is consistently good for the parameters that apply, including any pollutant tied to a stream impairment. |
| eDMR and annual report history |
You report on time, and your numbers trend the right way. |
| Compliance record |
No open violations, and past problems were resolved. |
| Before and after photos, drawings, and a current site map |
Exposure has been eliminated or reduced, with covers, berms, and outfalls shown clearly. |
| An updated PPC Plan |
The plan matches what's on site today, and employees are trained on it. |
| Records of operational changes |
A process ended, an activity moved indoors, or a wastewater stream was rerouted. |
One good sample doesn't build a case. DEP's NOI asks for two years of data, and a handful of clean results next to a few near-misses reads as luck. If your results have been high, work on the cause first. Our articles on benchmark values versus effluent limits and what to do when sampling results are high are good places to start. Keeping a facility in a no exposure condition also depends on the people working there, so the online environmental training library is a practical way to keep your team on the same page.
What Are the Risks of Overpromising a Move Off an Individual Permit?
DEP decides, and it decides after reviewing your NOI or NEC application along with your monitoring data. It can deny PAG-03 coverage and keep you on an individual permit, and a No Exposure Certification isn't guaranteed either. If a request is denied, your existing permit stays in force and so do its requirements. That's why you should never treat a pending request as a replacement for your current obligations. Keep sampling, keep filing, and keep your renewal dates in view. Individual permits generally run five years, and DEP's renewal application is due at least 180 days before expiration if you'll keep discharging, so ask your regional office how a pending NOI interacts with that date.
PAG-03 also doesn't authorize stormwater discharges from a facility covered by an individual permit when general permit coverage would mean less stringent limits or terms. In plain words, DEP won't let a move loosen protections your individual permit was written to provide. A facility that wins No Exposure carries duties too. If conditions change so the facility no longer qualifies, it has to notify DEP immediately and file an NOI for permit coverage, and adding exposed materials, new equipment outdoors, or a new activity can trigger that. Some facilities end up spending real money on covers and enclosures only to learn that DEP's review turns up a reason the move won't work.
Be wary of any consultant who guarantees DEP's approval. We don't, because we can't. If your individual permit grew out of a consent order or an enforcement dispute, an environmental attorney may be appropriate before you file anything, since what you tell DEP in an NOI or NEC application can bear on the enforcement side too.
What Do the Fees and Costs Look Like for PAG-03 and No Exposure?
The agency fees are modest next to the work behind them. For PAG-03, DEP's permit sets an annual NOI installment of $500, due each March 23, and DEP's materials list a $500 NOI filing fee for new coverage. A No Exposure Certification carries a $500 fee every five years with the NOI and NEC application, with no annual fee. Payments run through DEP's GreenPort system. How DEP treats fees when an existing individual permittee converts can vary, and individual permit fees and amendment fees are set separately, so confirm the current numbers with your regional office and DEP's published fee schedule before you budget.
Most of the cost lies in the preparation. That means the sampling, the site evaluation and mapping, the PPC Plan, any physical changes to reach no exposure, and the paperwork itself. What drives it is how many outfalls you have, how big and complicated the site is, whether a current PPC Plan already exists, and how much sampling data you've already built up. Our article on what a PAG-03 permit costs in Pennsylvania breaks those drivers down, and the pricing calculator below gives an estimate for RMA's help with your stormwater permitting.
How Can RMA Help With Moving Off an Individual Stormwater Permit?
We work with Pennsylvania facilities on PAG-03, individual permits, and No Exposure Certifications all the time, and the first thing we do is read your permit and its fact sheet to find out why DEP chose an individual permit. From there we can tell you whether PAG-03 or No Exposure looks realistic, and we'll say so plainly when staying put is the better call. If a move makes sense, we help with the sampling, the PPC Plan, the site maps, the NOI or NEC package, and the questions DEP sends back. We don't handle construction-phase permits, so if the plan involves new roofs or buildings, we'll point you toward the right engineer or contractor and help with the operational permits and plans you'll need once the site is running.
There's no pressure and no obligation. You can call us, send an email, or fill out the form on our website, and tell us what's happening at your facility. When you're ready to talk to RMA, we'll help you figure out the right next step.
