A permit by rule (PBR) is a process by which a facility that emits air pollutant(s) may register with DEQ in lieu of obtaining a site-specific Permit to Construct (PTC). A PBR is a simple and efficient alternative to an individual permit. In a PBR, requirements are spelled out in the rule and apply to all members of a particular industry.

Only facilities in certain industries (currently, rock crushers and certain dairies) may use a PBR instead of a PTC. Once registered, the facility is deemed to have a permit, thereby authorizing construction without the need to obtain a PTC before beginning operations.

The idea behind the PBR is to simplify the permitting process, minimize paperwork, and save time and money. The PBR registration fee is lower than the PTC application fee.
