Colorado has 128 overdue Title V permits.
EPA enforcement is back.

The Clean Air Act sets an 18-month statutory clock for a permitting authority to act on a complete Title V application, but actual times vary widely by state and by source complexity. In states with the worst backlogs, initial issuance and renewal cycles regularly run two to four years, and in some regions roughly 90 percent of Title V permits are operating under expired conditions because the agency has not gotten to the renewal yet. The single biggest driver of timeline is not the agency calendar; it is how many review cycles the application goes through after submittal. Pre-submittal completeness work and audit-trailed calculations are where most of the time is recovered.

Title V is the federal Clean Air Act operating permit program for major sources of air pollution, codified at 42 U.S.C. sections 7661 to 7661f and implemented through 40 CFR Parts 70 and 71. It does not by itself impose new emission limits. It consolidates all applicable Clean Air Act requirements for a facility into one enforceable operating permit. New Source Review (NSR), by contrast, is the preconstruction permit program. NSR applies before you build or modify a major source and sets the limits (PSD or nonattainment NSR). In practice, NSR sets the obligations and Title V is the document the facility has to operate under once construction is done.

A non-Title V air permit is a state-issued air permit for a source that falls below the major-source thresholds in 40 CFR Part 70. These are typically called minor-source permits, synthetic minor permits, or state operating permits, depending on the jurisdiction. They are issued under state authority rather than the federal Title V program, they are usually much faster to obtain, and they do not require the same public participation and EPA review steps. If your facility is genuinely a minor source, a non-Title V state permit is the right path and you do not need a Title V program at all.

Under 40 CFR Part 70, if you submit a timely and complete renewal application, your existing Title V permit terms remain in effect through an application shield until the agency acts on the renewal. That means you can keep operating, but it does not mean enforcement risk goes to zero. EPA has been increasing oversight on lapsed and expired permit conditions, and citizen suits under the Clean Air Act can still proceed. The application shield protects the operator from a lapse caused by agency delay, not from underlying compliance issues.

Three things compound. First, the queue is growing faster than agencies can hire their way out of it. Colorado, for example, went from 111 overdue permits in 2022 to 128 in 2026 despite tens of millions of dollars in additional staffing. Second, EPA has resumed downgrades of air quality area classifications, which has pulled over 100 additional sources into major-source applicability. Third, every public-comment round, every agency request for additional information, and every revised dispersion run resets weeks of internal review. The bottleneck is not headcount alone; it is the iteration count per application.

The Title V permit shield is the provision in 40 CFR 70.6(f) that says compliance with the Title V permit is deemed compliance with the applicable Clean Air Act requirements that are specifically identified in the permit. It is one of the main reasons facilities want a clean, well-written Title V permit on file. A correctly drafted shield reduces ambiguity for the operator, the agency, and the community about what is and is not enforceable. It does not cover requirements that were left out of the permit, which is one reason the application phase matters so much.

The fastest gains are upstream of the agency, not inside it. Start with a complete and reproducible emissions inventory tied to the actual operating data, run a pre-submittal health risk screen so health-impact questions surface before the agency reviewer raises them, and use a shared workspace where the agency can see the same inputs the applicant sees instead of trading PDFs. The Chevron Richmond Refinery experience is a recognizable example of how expensive a slow, contested permit cycle can become. The goal is to give the reviewer something they can reproduce on the first pass.

No. LSARS does not write your permit and does not file it. Your team or your environmental consulting firm does that work, and the responsible facility is always the entity of record. LSARS shortens the iteration loop by giving the applicant and the agency reviewer the same view of emissions, dispersion, and health risk math, with an audit trail for every number. Traditional firms (ALL4, RTP Environmental, Trinity, Eastern Research Group) are legitimate partners, not competitors. They can use LSARS as the underlying calculation engine.
