A Title V Air Operating Permit Application is the form a “major source” of air pollution files with its state or local air agency to get one federal operating permit that lists every clean-air rule the facility must follow. You file it because the Clean Air Act makes this permit the master rulebook for your plant, and operating a major source without one is illegal.
This guide walks you through the application the way a 30-year permit writer would. Federal law sets the frame, but the actual form comes from your state or local air district, so the examples here follow a widely used model: the San Joaquin Valley Title V form in California, with EPA rules cited throughout. About 16,000 major sources hold Title V permits across the country, and a single math error in your potential-to-emit numbers can pull a small facility into this program or push a major source out of compliance.
Here is what you will learn:
- 📋 Who counts as a “major source” and must file this form
- 🧮 How to calculate potential-to-emit (PTE) without triggering a costly mistake
- ✍️ How to fill out every section line by line, with real sample entries
- 📎 Which attachments and certifications make or break your application
- ⏰ The deadlines, fees, and penalties that decide whether you stay legal
What the Form Is and Who Must File It
The Title V Operating Permit Application is the document that turns a scattered pile of air rules into one enforceable permit. The program comes from Title V of the 1990 Clean Air Act and is run by states and local districts under 40 CFR Part 70. The U.S. EPA sets the floor, your state agency writes the permit, and EPA keeps a 45-day veto window over every permit your district proposes.
You must file if you are a “major source.” The EPA major source rule sets the default threshold at 100 tons per year of any regulated air pollutant. For hazardous air pollutants (HAPs), the line drops to 10 tons per year of a single HAP or 25 tons per year of any mix of HAPs. In areas that fail to meet air-quality standards, the trigger falls further, down to 25 tons per year for VOC or NOx in a “severe” ozone area and as low as 10 tons per year in an “extreme” area.
Some sources must file no matter how small they are. The EPA applicability list names acid-rain “affected sources,” solid-waste incineration units under Section 129, and several non-major sources tied to specific NESHAP rules, such as Portland cement plants and secondary lead smelters. Municipal solid waste landfills with a design capacity at or above 2.5 million megagrams also fall in.
The consequence of guessing wrong is steep. If you are a major source and skip this form, you operate illegally and face federal civil penalties that can exceed $100,000 per day per violation under Clean Air Act enforcement. Marcus runs a metal-finishing plant whose solvent use pushes HAP emissions to 12 tons per year, so even though he feels small, he is a major source and must file.
Before You Start: Documents and Information You Need
Gather your paperwork before you open the form. A Title V application is built from data you already keep, but pulling it together first prevents the half-finished drafts that stall most filings. Skipping any one of these items is the top reason agencies return an application as “incomplete,” which restarts your clock.
Here is your pre-filing checklist:
- Facility legal name and mailing address. The agency cross-checks this against your existing permits, and a mismatch delays your file number assignment.
- Air district facility ID number. Without it, the agency cannot link your application to your current permits, and your file may be misrouted.
- Standard Industrial Classification (SIC) or NAICS code. This tells the agency which industry rules apply, and the wrong code can attach the wrong standards.
- A complete list of every emission unit. Missing a unit means it stays out of your permit and becomes an enforcement target later.
- Potential-to-emit (PTE) calculations for each pollutant. These set your major-source status, and bad math here can void the whole application.
- Control equipment specifications. The agency needs make, model, and efficiency to confirm your emission limits, and gaps trigger requests for more data.
- Current permit conditions and applicable requirements. You must list every rule that applies, because Title V is a “rule roundup” and leaving one out makes the permit unenforceable.
- Responsible official name and title. Only this person can sign, and naming the wrong person invalidates your certification.
- Compliance status for each requirement. You certify whether you comply now, and a false statement is a federal crime.
- Filing fee payment. Most districts will not process an unpaid application.

Where to Get the Form and How to Access It
You get the Title V application from the air agency with jurisdiction over your facility, not from EPA directly. EPA hosts the national program page at EPA Title V permits, but the downloadable form lives on your state or local district site. In California’s Central Valley, the form sits on the Valley Air Title V forms page, where the initial and renewal versions are identical.
Most agencies post the form as a fillable PDF. You can type into it, save it, and print it for the wet signature the responsible official’s certification requires. Always check the revision date printed on the form before you start, because an outdated form can be rejected and force a refiling.
Some districts now offer an online permitting portal that lets you upload the same data through a web interface. The Pennsylvania air permit page, for example, lists its Title V form as 2700-PM-BAQ0010 alongside electronic options. If your district offers both, the paper PDF and the portal collect the same information, so pick the channel that matches how you keep records.
Step-by-Step: How to Fill Out the Title V Application Line by Line
This is the heart of the form. Work through it in order, because later sections build on the facility data you enter first. Each field below shows what it asks, how to answer, a sample entry, an edge case, a common mistake, and a misconception to drop.
Section 1: Facility Name and Physical Address
This field asks for the legal name of your business and the street address where the equipment actually sits. Enter the full legal entity name exactly as it appears on your incorporation papers, then the physical address, not a mailing P.O. Box. Marcus enters “Valley Metal Finishing, Inc.” and “1420 Industrial Way, Fresno, CA 93725.”
What if your mailing address differs from the plant site? Use the physical location here and put the mailing address in the separate contact field, because the agency inspects the physical site. A common mistake is entering a corporate headquarters address in a different city, which sends inspectors to the wrong place and stalls processing. Many filers wrongly believe the “facility” is the company; in Title V the facility is the physical site where emissions happen.
Section 2: Air District Facility ID Number
This field asks for the identification number your district already assigned to your plant. Copy it from your current permit or your annual emission statement, and enter it digit for digit. Janet writes “S-1234-0” from her glass plant’s existing permit.
What if you have never held a permit and have no ID? Leave it blank and write “new facility,” because the agency assigns the number when it opens your file. The common mistake is inventing or guessing a number, which mislinks your application to another company’s record. Filers often think this number is the same as their EPA registry ID; it is not, and mixing them confuses the agency’s database.
Section 3: Standard Industrial Classification (SIC/NAICS) Code
This field asks which industry category your operation falls under. Look up the code that best matches your primary product or service and enter the full digits. Marcus enters NAICS “332813” for electroplating and metal coating.
What if your plant does two unrelated things? List the code for the operation that generates the most emissions, because that drives which standards apply. The common mistake is choosing a code for a minor side activity, which can attach the wrong NESHAP and force a rewrite. People wrongly assume this code is just for statistics; it actually steers which federal rules the agency writes into your permit.
Section 4: Responsible Official Contact Information
This field asks for the person legally able to bind the company and certify the application. Enter the name, exact title, phone, and email of a corporate officer or a plant manager who meets the 40 CFR Part 70 definition of “responsible official.” Janet enters “Robert Chen, Plant Manager, (559) 555-0147, rchen@valleyglass.com.”
What if a consultant prepares the form? The consultant can fill in data, but only the responsible official may sign the certification, so this box must name the official, not the consultant. The common mistake is listing the environmental coordinator who lacks signing authority, which makes the certification invalid. Many filers think any manager can sign; the rule limits this to officials who meet the federal definition, often by emissions size or corporate rank.
Section 5: Emission Units Inventory
This section asks you to list every piece of equipment that releases air pollution. Create one line per unit with a unique ID, a description, the maximum rating, and the year installed. Marcus lists “EU-1, chrome plating tank, 500 amp rectifier, installed 2018.”
What if you have dozens of identical small units? You may group truly identical units only if your district allows it, but when in doubt list them separately to avoid an enforcement gap. The common mistake is forgetting a backup generator or a small heater, which leaves that unit out of the permit and exposed to a future violation. Filers often believe insignificant activities can be ignored; most districts still require you to list them, even if they carry lighter requirements.
Section 6: Emissions and Potential-to-Emit (PTE)
This section asks for each unit’s actual and potential emissions of every regulated pollutant. Calculate PTE as the maximum the unit can emit running full-time at full capacity, then apply any federally enforceable limits. Janet reports the glass furnace at “NOx PTE 96 tons/year” after her permitted limit.
What if a permit limit caps your hours or throughput? You may use that limit to lower PTE only if it is federally enforceable, such as a synthetic-minor condition. The common mistake is reporting actual emissions in the PTE box, which understates your status and can be treated as a false statement. People wrongly think PTE means “what we really emit”; it means the most you could emit under your physical and legal limits.
Section 7: Applicable Requirements
This section asks you to list every air rule that applies to each unit, citing the rule by number. Pull citations from your current permits, federal NSPS and NESHAP subparts, and district rules, then match each to the right unit. Marcus cites “40 CFR Part 63, Subpart N” for his chrome plating tank.
What if you are unsure whether a rule applies? List it and note your reasoning, because a Title V permit must capture all applicable requirements and omissions make it unenforceable. The common mistake is leaving out a recently promulgated MACT standard, which voids the “complete” status of your permit. Filers often assume the agency will fill in missing rules; the burden is on you, and the agency reviews what you submit.
Section 8: Compliance Plan and Certification of Compliance
This section asks whether you currently comply with each listed requirement and, if not, how you will get there. Mark each requirement as in compliance or not, and for any gap attach a schedule with milestones. Janet certifies “in compliance” for all furnace limits and attaches monitoring records.
What if you are out of compliance on one rule? Say so and submit a compliance schedule, because hiding it converts a fixable gap into a federal false-certification crime. The common mistake is checking “in compliance” everywhere to look clean, which exposes the signer to criminal liability. People wrongly believe the compliance plan is optional; it is a core part of Title V and the agency reads it closely.
Section 9: Responsible Official Signature and Certification
This final block asks the responsible official to sign under penalty of law that the application is true, accurate, and complete. The official signs by hand, prints the title, and dates the form using MM/DD/YYYY. Robert Chen signs and writes “06/03/2026.”
What if the official is traveling at the deadline? Plan ahead, because an electronic or delegated signature is valid only if your district and the federal rule allow it. The common mistake is letting a subordinate sign for the official, which invalidates the certification. Many filers think the signature is a formality; it is a sworn legal statement, and a knowing false signature can bring criminal charges.
Three Filled-Out Examples Using Real Scenarios
Below are three common fact patterns, each following one filer through the major sections of the form.
Scenario 1: Initial permit for a manufacturing plant. Marcus files his first Title V application after a new line pushed his metal-finishing plant over the HAP threshold.
| Form Section | What Marcus Enters |
|---|---|
| Facility Name and Address | Valley Metal Finishing, Inc., 1420 Industrial Way, Fresno, CA 93725 |

| Compliance Status | In compliance with proposed cap |
| Goal | Avoid Title V via synthetic-minor limit |
How to File the Completed Form
You file the Title V application with your air district through whatever channels it offers. Always keep proof of filing, because your application date sets your compliance clock and your “application shield” against enforcement.
- By mail. Send the signed form and attachments to your district’s permit-services address, such as the San Joaquin Valley district offices in Fresno, Bakersfield, or Modesto. Pay the fee by check, allow several months for completeness review, and keep your certified-mail receipt as proof.
- In person. Hand-deliver to the district counter, pay by check or card where accepted, and ask for a date-stamped copy as your proof of filing.
- Online portal. Where offered, upload the form and pay by electronic payment, as the Pennsylvania portal allows, then save the confirmation number and email receipt.
- By email or fax. Some districts accept emailed PDFs for the data but still require a mailed original signature page; confirm the rule and keep the sent-mail confirmation.
Fees vary widely by district and are often tied to your tons of emissions, so check your agency’s current fee schedule before you submit. The deadline for an initial application is generally within 12 months of becoming a major source, and renewals are usually due 6 to 18 months before your permit expires.
What Happens After You File
Once you file, the agency reviews your application for completeness, usually within 60 days. If it is complete, you gain an “application shield” that lets you keep operating while the permit is written, as long as you filed on time. If it is incomplete, the agency sends a deficiency letter and your shield depends on a timely fix.
The agency then drafts your permit, opens a public comment period, and sends the proposed permit to EPA for a 45-day review. EPA can object during this window, and the public can petition EPA even after that. Most permits take 12 to 18 months from a complete application to final issuance.
After issuance, your permit lasts five years. You must submit an annual compliance certification and report deviations, because the Ohio EPA program and others require yearly certification of whether you met every permit term. Missing that annual certification is itself a violation, even with a valid permit.
Mistakes to Avoid When Filling Out the Form
- Reporting actual emissions as PTE. This understates your status and can be read as a false statement.
- Forgetting a small emission unit. The unit stays out of the permit and becomes an enforcement target.
- Citing the wrong NAICS code. The agency attaches the wrong rules and forces a rewrite.
- Omitting a recent MACT or NSPS rule. Your permit is not truly complete and can be reopened.
- Letting an unauthorized person sign. The certification is invalid and the application fails.
- Checking “in compliance” when you are not. This turns a fixable gap into a federal crime.
- Using a P.O. Box as the facility address. Inspectors cannot find the site, delaying review.
- Filing on an outdated form version. The agency may reject it and restart your clock.
- Skipping the filing fee. Most districts will not process an unpaid application.
- Missing the 12-month or renewal deadline. You lose your application shield and risk daily penalties.
- Leaving the facility ID blank when you have one. Your file gets mislinked or misrouted.
- Failing to keep proof of filing. You cannot prove your application date if disputes arise.
Do’s and Don’ts
Do:
- Do double-check your PTE math, because it decides whether you are even in the program.
- Do list every applicable rule, since Title V exists to gather them in one place.
- Do keep a dated copy of everything, because your filing date protects you.
- Do use exact rule citations, so the agency can confirm each requirement.
- Do file early, because completeness review and EPA review take many months.
- Do confirm your signer qualifies, since only a responsible official may certify.
Don’t:
- Don’t guess at a facility ID, because a wrong number mislinks your record.
- Don’t hide a compliance gap, since a false certification is a federal crime.
- Don’t ignore insignificant units, because most districts still require listing them.
- Don’t use a homepage form, because outdated versions get rejected.
- Don’t let a deadline slip, since penalties can exceed six figures per day.
- Don’t skip the attachments, because missing data makes your file incomplete.
Pros and Cons of Filing on Your Own vs. With Help
| Filing on Your Own | Filing With a Consultant |
|---|---|
| Saves consultant fees, which helps a tight budget | Costs more, but spreads the workload at peak times |
| Builds in-house knowledge of your own rules | Brings deep PTE and MACT experience that prevents errors |
| Full control over timing and data | Adds a coordination step but reduces rework |
| Risk of missing an applicable requirement | Lower risk of omissions that void completeness |
| You carry all the certification responsibility | The official still signs, but the prep is reviewed by experts |
Filing on your own works best for a simple, single-process facility where one manager knows every rule. Hiring help pays off for complex sites with many units, overlapping MACT standards, or a tight deadline, because the cost of a rejected application often exceeds the consultant fee.
FAQs
Do I have to file if my emissions are just under 100 tons per year?
No. You generally avoid Title V below the threshold, but lower limits apply for HAPs and in non-attainment areas, and certain small sources must file regardless of size.
Is the Title V form the same for an initial permit and a renewal?
Yes. In many districts, including the San Joaquin Valley, the initial and renewal application forms are identical, though you mark the filing type and update your data.
Do I write actual emissions or potential emissions in the PTE box?
No, you do not write actual emissions. You enter potential-to-emit, the most the unit could release at full capacity under federally enforceable limits.
Do I list my corporate headquarters or the plant site as the facility address?
No, not the headquarters. You enter the physical site where the equipment operates, because the agency inspects that location.
Can my environmental consultant sign the certification for me?
No. Only the responsible official defined under federal rules may sign, though a consultant may prepare the data.
Do I need to list small or “insignificant” emission units?
Yes, in most districts. You list them even if they carry lighter requirements, because omitting them creates an enforcement gap.
Is there a deadline to file my initial application?
Yes. You generally must apply within 12 months of becoming a major source, and missing it risks daily penalties.
Do I include a backup generator on the emission unit list?
Yes. A backup generator is an emission unit and must be listed, or it falls outside your permit and becomes a violation risk.
Can I keep operating while my permit is being written?
Yes, if you filed a timely and complete application. The “application shield” protects you during the review period.
Does EPA review my permit before it is final?
Yes. Your district sends the proposed permit to EPA for a 45-day review, and EPA can object during that window.
Do I have to do anything after I get the permit?
Yes. You must submit an annual compliance certification and report deviations, and missing it is its own violation.
Can I lower my PTE by limiting my operating hours?
Yes, but only if the limit is federally enforceable, such as a synthetic-minor condition written into your permit.
Is a synthetic-minor limit a way to avoid Title V entirely?
Yes. Accepting enforceable caps that keep you below the major-source threshold lets you stay out of the Title V program.
Do I need to cite the specific federal rule numbers in the applicable-requirements section?
Yes. You cite each rule by its CFR subpart or district rule number, because vague references make the permit unenforceable.
