Rock Crushing Plant
This guidance is intended to help applicants prepare applications and certifications with a reduced amount of effort, yielding clearer and more accurate applications. We hope to steer new applicants around some common mistakes, allowing them to prepare applications which are complete on their first try.
The process involves preparation of facility descriptions, emissions estimates, and completion of some administrative forms. Two passes through the process may be required, calculating emissions and adjusting emissions if any level of significance is exceeded.
The pollutants of concern is particulate matter. If the facility has stationary engines (such as generators), you will also need to address nitrogen oxides (NOx), carbon monoxide (CO), and volatile organic compounds (VOC), particulate matter (PM), and sulfur dioxide (SO2). These are referred to a "criteria pollutants."
In addition, there may be emissions of hazardous air pollutants (HAPs), primarily formaldehyde.
In general, a rock crushing plant will have a primary crusher, primary screen, secondary crusher(s) and secondary screen(s), and associated conveyors and stockpiles. It may also involve portable generators powered by diesel engines. Emissions of each criteria pollutant must be less than 100 TPY for the facility to be a minor source. Information as listed here may be attached to the application. Example formats are provided in this document.
Administrative Forms
The first thing to do is acquire a copy of the forms A. Log onto the DEQ web page: www.deq.state.ok.us
B. Go to the "Air Quality" page
C. Select "Forms"
D. Select either "Rock Crushers & Sand & Gravel Application" or "Non-metallic Mineral Processing Minor
Facility Air Quality General Permit Application."
If you download the MS Word copies of these documents, they may be filled in on computer and stored for later needs.
On the "General Facility Information" Form 100-884, please do not mark both construction and operating permits as this makes your application self-contradictory.
Construction permits and operating permits are applied for separately. Minor source applications are all listed as "Tier I." The “SIC Code†means "Standard Industrial Classification Code," 1422 for limestone, 1423 for granite, 1429 for other crushed stone, 1442 for sand and gravel, and 1221 for coal.
The "Landowner Notification Affidavit" must be completed and signed for all applications, but it is commonly overlooked, resulting in delays in processing applications and issuing permits.
Rock Crushing Plant Fees
Minor source operating permits will require a $500 fee, while a General Operating Permit authorization requires a $150 fee. GOP authorizations for construction require a $400 fee for all minor sources. Permits for specific facilities (everything other than General Operating Permit authorizations) fees depend on the emissions being added. For example, adding emissions of 30 TPY to a facility with current permitted emissions of 50 TPY means the construction permit application fee is $1,000.
In a reverse situation (adding 50 TPY to a facility with 30 TPY permitted emissions), the construction permit fee would be $1,500. Numerous other situations are addressed in the minor source permits rule, OAC 252:100-7, but these situations are not as common. The main differences between using a site-specific permit and a General Operating Permit are in the amount of text in the permit and the amount of time normally spent in processing.
