A Title V air permit is the federal operating permit that facilities emitting regulated air pollutants above certain thresholds must hold under the Clean Air Act. The permit consolidates every federal air quality requirement that applies to your facility into a single document covering emission limits, monitoring methods, recordkeeping duties, and reporting schedules.1US EPA. 1990 Clean Air Act Amendment Summary: Title V It is issued by your state or local permitting authority (or, in some cases, directly by the EPA), lasts five years, and carries continuing compliance obligations for every day of that term.
Who Needs a Title V Permit
Federal law makes it illegal to operate certain stationary sources without a Title V permit. The broadest category is any “major source,” defined as a facility with the potential to emit 100 tons or more per year of any regulated air pollutant. Hazardous air pollutants have a lower bar: 10 tons per year of any single hazardous air pollutant or 25 tons per year of any combination.2US EPA. Who Has to Obtain a Title V Permit?
Those default thresholds drop significantly in areas that don’t meet national air quality standards. In a “serious” nonattainment area, the major source threshold for volatile organic compounds or nitrogen oxides falls to 50 tons per year. In “severe” areas it drops to 25 tons per year, and in “extreme” nonattainment areas it can be as low as 10 tons per year.2US EPA. Who Has to Obtain a Title V Permit? A facility that would stay comfortably below 100 tons in an attainment area may be a major source the moment it’s located in one of these regions.
Major sources aren’t the only ones covered. Permits are also required for any source subject to New Source Performance Standards or National Emission Standards for Hazardous Air Pollutants, any source required to have a preconstruction permit under the Prevention of Significant Deterioration or Nonattainment New Source Review programs, acid rain sources, and any other source category the EPA designates by regulation.3Office of the Law Revision Counsel. 42 U.S.C. 7661a – Permit Programs Even smaller “area sources” can be pulled in through one of those federal standards.
One notable boundary: the U.S. Supreme Court ruled in 2014 that greenhouse gas emissions alone cannot make a source “major” for Title V purposes. Facilities do not need a permit based solely on carbon dioxide output.4US EPA. Clean Air Act Permitting for Greenhouse Gases
Potential to Emit and the Synthetic Minor Option
Whether a facility crosses these thresholds depends on its “potential to emit,” meaning the maximum pollution the source could release running at full capacity, 24 hours a day, 365 days a year, with no controls in place beyond those permanently built into the design.5US EPA. Potential to Emit (PTE) Guidance for Specific Source Categories It is a worst-case number, so many facilities have a potential to emit well above their actual day-to-day emissions.
A facility that would otherwise be major can accept legally enforceable limits on its operations, such as caps on hours of operation, production volume, or fuel usage, to bring its potential to emit below the threshold. The result is called a “synthetic minor” source. Any restriction used to lower potential to emit must be enforceable by the EPA, not just a voluntary company policy.5US EPA. Potential to Emit (PTE) Guidance for Specific Source Categories
The synthetic minor route avoids the cost and administrative burden of a full Title V permit, but the limits are real. The facility must actually comply and keep records to prove it. Exceed a limit even once, and the facility may retroactively become a major source that has been operating without the required permit, creating serious enforcement exposure.
What Goes Into a Title V Application
The federal regulations at 40 CFR Part 70 (for state-run programs) and Part 71 (for EPA-administered programs) set out detailed application requirements. At minimum, an application must include:
- Company and plant names, addresses, owner information, and contact details.
- A description of each industrial process and product, classified by Standard Industrial Classification code.
- Emissions of every regulated air pollutant from every emission unit, reported in tons per year and in whatever additional units are needed to show compliance with applicable standards, with supporting calculations.
- Identification and description of each point where pollutants are released, in enough detail to establish fee liability and which regulations apply.
- Description of all pollution control devices and compliance monitoring instruments.
- A citation and description of every federal requirement that applies to the source, including any required test methods for demonstrating compliance.
- A compliance plan showing how the facility meets, or will meet, each applicable requirement. If the facility is currently out of compliance, the plan must include a remedial schedule with milestones and a projected completion date.
A responsible official, typically a senior executive or plant manager, must sign the application and certify the accuracy of everything submitted. Federal law treats a false certification as a criminal offense carrying up to two years in prison, so this signature carries real personal liability.7Office of the Law Revision Counsel. 42 U.S.C. 7413 – Federal Enforcement
Federal rules also let permitting authorities approve lists of “insignificant activities” that can be excluded from the detailed emissions analysis, though they must still be listed in the application.6eCFR. 40 CFR 70.5 – Permit Applications The exact list varies by permitting authority, so check with your state or local agency before assuming an exemption applies.
How Review and Approval Works
Once you file, the permitting authority has 60 days to decide whether the submission is complete. If the agency doesn’t act within that window, the application is generally deemed complete by default. An incomplete submission is sent back with a request for additional information, and the clock resets.
After the application clears the completeness check, the permitting authority drafts a proposed permit and puts it out for public review. Federal regulations require at least 30 days for public comment, and the agency must give at least 30 days’ advance notice of any public hearing.8eCFR. 40 CFR 70.7 – Permit Issuance, Renewal, Reopenings, and Revisions Affected neighboring states also receive notice and can submit objections.
After public comment closes, the EPA has 45 days to review the proposed permit. If the EPA objects, the permitting authority must revise the permit to address those objections before it can be finalized. If the EPA does not object, the public gets a further 60-day window to petition the EPA to reconsider.9US EPA. Title V Petitions With state agency review, EPA review, and public petition stacked back to back, the process from application to final permit routinely takes well over a year.
Permit Fees
Title V programs are funded by the facilities they regulate. Federal law requires that fees cover all reasonable costs of running the permit program, including application review, compliance inspections, and emissions monitoring oversight.10US EPA. Permit Fees
The EPA sets a “presumptive minimum fee” that state programs can use as a benchmark. For September 2025 through August 2026, that rate is $65.38 per ton of regulated pollutant emitted per year.11Environmental Protection Agency. Calculation of the Part 70 Presumptive Minimum Fee The rate is adjusted every September based on the Consumer Price Index.
Most states don’t use the federal presumptive fee directly. They set their own structures, which can differ substantially. Some charge flat application fees, others charge per-emission-unit fees, and many layer annual maintenance fees on top of per-ton charges. Total cost to obtain and maintain a permit varies widely depending on your state and the complexity of your facility. Contact your permitting authority for the schedule that applies to you.
Compliance and Reporting After the Permit Issues
Getting the permit is the start, not the finish. A Title V permit lasts five years and imposes ongoing obligations every day of that term.
Monitoring and Recordkeeping
Every permit must contain monitoring requirements sufficient to demonstrate compliance with each emission limit and operational standard. Depending on the source, that can mean continuous emissions monitoring systems, periodic stack testing, process parameter tracking, or detailed recordkeeping designed to serve as monitoring. All monitoring records, including dates, times, methods, results, and operating conditions at the time of measurement, must be retained for at least five years.12eCFR. 40 CFR 70.6 – Permit Content
Semi-Annual Reports and Annual Certification
Permit holders must submit monitoring reports at least every six months, identifying every instance where the facility deviated from a permit requirement. At least once a year, the facility must also submit a compliance certification covering every term and condition in the permit. The certification identifies each permit condition, describes the method used to determine compliance, states whether compliance was continuous or intermittent during the period, and accounts for every deviation. The annual certification goes to both the permitting authority and the EPA.12eCFR. 40 CFR 70.6 – Permit Content
Deviations must also be reported promptly. The exact prompt-reporting deadline is set by the individual permitting authority rather than a uniform federal rule. Some states require notification within 24 hours for significant deviations; others allow several days. The deadline that applies to you is written directly into your permit.
Renewal and the Application Shield
Title V permits expire after five years. Federal regulations generally require facilities to submit a complete renewal application between 6 and 18 months before the current permit expires. Missing this window creates a coverage gap that can expose the facility to enforcement.
Filing a timely and complete renewal application triggers what’s known as the “application shield.” If your renewal is in on time and the permitting authority simply hasn’t finished processing it before your current permit expires, you can keep operating. The lack of a valid permit during the gap is not a Clean Air Act violation, as long as the delay isn’t caused by your failure to provide information the agency requested.13Office of the Law Revision Counsel. 42 U.S.C. 7661b – Permit Applications The protection matters because renewals often take longer than 18 months to process.
The shield only protects against the charge of operating without a permit. It does not excuse the facility from complying with the substantive emission limits and monitoring requirements in the expired permit. You still have to follow all the rules; you just won’t be penalized for the missing paperwork.
Penalties for Noncompliance
Operating without a required permit, violating permit conditions, or failing to meet applicable Clean Air Act requirements can trigger both civil and criminal enforcement.
Civil Penalties
The Clean Air Act authorizes civil penalties for each day a violation continues. After the most recent inflation adjustment, the maximum civil penalty is $124,426 per day per violation, a figure the EPA updates periodically under a congressionally mandated inflation formula.14eCFR. 40 CFR 19.4 – Statutory Civil Penalties as Adjusted for Inflation A facility with multiple violations running for months can face penalties in the millions. The EPA calculates actual amounts case by case based on severity, the economic benefit the violator gained from noncompliance, and the facility’s compliance history.
Criminal Penalties
Knowing violations are treated differently. A person who knowingly operates without a required permit or knowingly violates a permit condition faces up to five years in federal prison per offense, plus fines. For repeat offenders, both the maximum prison term and the fine double. A separate provision covers anyone who knowingly makes a false statement in a permit application, monitoring report, or compliance certification, and that carries up to two years in prison, doubled for a second conviction.7Office of the Law Revision Counsel. 42 U.S.C. 7413 – Federal Enforcement That is why the responsible official’s signature on the application and annual certification is treated as more than a formality.
