Stationary or Portable Rock Crushers (General Order)

What is the Purpose of this General Order?
The Department of Ecology (Ecology) issues general orders to businesses to make sure Washington meets state and federal air quality requirements. A general order is a group permit that simplifies the air permitting process. When several sources of the air pollution are similar, Ecology can issue a “general order” for all the sources, rather than a series of individual permits. A general order permit limits the amount of air pollutants a business can emit. It is different from the Notice of Construction process because all of the work is done up front. Because the majority of the work has been done up front, the time necessary to gain approval from Ecology is greatly reduced.
Who Issues this General Order?

Permit Timeliness Results

Permit Timeliness data collection is in response to a State Auditor’s Performance Audit and RCW 43.42A. Each regulatory agency developed a plan to improve permit clarity, predictability, and timeliness. Each agency considers the customers experience to ensure permit assistance is simple to use, easy to access, and designed in a customer-friendly manner. Agencies report progress to the Governor’s Office for Regulatory Innovation and Assistance (ORIA). ORIA prepares and distributes reports, with participation from the State Auditor’s Office and Results Washington. See latest report here:

All permits submitted for reporting were entered into this Regulatory Handbook. Here are the results of the performance data:

Estimated Time Required By the Agency to Process a Permit Application (Definition)
Average number of days from Receipt to Complete: 4
Maximum number of days from Receipt to Complete: 19

Estimated Time Required By the Agency to Issue a Permit Decision (Definition)
Average number of days from Complete Application to Decision: 32
Maximum number of days from Complete Application to Decision: 51

The general order permits are not tracked individually so the results are combined for General Order of Approval for: Asphalt Plants, Auto Body Shops, Concrete Batch Plants, Dairy Manure Anaerobic Digesters, Gas Fired Emergency Electrical Generators, Perchloroethylene Dry Cleaners, Small Boilers Using Natural Gas, Propane, or Diesel Fuel, and Stationary or Portable Rock Crushers.
