Permits, complaints & compliance.

If you operate stationary equipment that emits air pollution, you need a District permit. If you smell smoke or see a violation, file a complaint online or by phone. If you're not sure what applies to you, the permit-finder below sorts it out.

File a complaint

Concerned about smoke, dust, odors, or a possible violation? The District takes complaints by phone (24/7) or online form (8 a.m. – 5 p.m. Mon–Fri response).

Which permit do I need?

The District issues two core permit types for stationary sources:

  • Authority to Construct (ATC) — required before installing, modifying, or replacing emissions-generating equipment. Apply before construction.
  • Permit to Operate (PTO) — required after construction is complete and the equipment is ready to operate. Renews annually.

Common permit categories

Stationary sources
Boilers, engines, paint booths, gas stations, dry cleaners, food processors. Forms 01–07 in the current forms library.
Agricultural
Operating permits for large ag sources, confined animal facilities (dairies), ag engine registrations > 50 HP, portable equipment registration. Form 1015 + ag burn permit.
Asbestos NESHAP
Federally delegated; 10-day notification window; required even for residential > 4 units. Form 170.
Oil & gas
Stationary source permits for upstream and midstream operations in the District. Form OG.
Annual Throughput Reports
Required for all permitted facilities, due annually. Currently submitted via JotForm.

A redesign note: forms-finder coming in Year 1

The current site lists 50+ forms in seven categories as a static list. The redesigned forms page becomes a sortable, searchable table filtered by who you are (operator type), what equipment you're permitting, and where you are in the lifecycle (new permit, modification, renewal, retirement). PDF forms get an accessible-PDF version; the most-used forms migrate to JotForm where possible per FAQ #8.

Payments

Permit fees, late fees, and annual renewals are paid through AllPaid (the District's current payment processor). The redesign keeps the AllPaid integration in place; the wrapper page around it gets a cleaner UX and clear receipts.
