Water Quality Regulations
 
Portable rock crushing facilities (rock crushers), also known as nonmetallic mineral processing plants, are impacted by various federal, state, and local environmental regulations depending on the activities conducted.
 
 Air Quality Regulations
Air quality regulations that impact portable rock crushing facilities include New Source Performance Standards, Permit by Rule, and Portable Equipment Relocation Registration.  Portable rock crushers also must comply with DEQ's fugitive dust, visible emissions, and open burning regulations.
 
For more information on these rules visit:

 Hazardous Waste Regulations
Portable rock crushers can generate hazardous waste and, therefore, must comply with the federal Resource Conservation and Recovery Act (RCRA), which is administered by DEQ. Under RCRA, facilities that generate hazardous waste are required to follow specific practices and procedures associated with the safe management of hazardous waste. The type and number of requirements that must be complied with are based on the quantity and type of waste generated. Click here to learn more about hazardous waste requirements on this Web site.
 
 Water Quality Regulations

Portable rock crushers can have an impact on Idaho's surface and ground waters and may be subject to federal water quality standards and the National Pollutant Elimination Discharge System (NPDES) program. Under this program, the U.S. Environmental Protection Agency (EPA) regulates the discharge of pollutants into any water body of the U.S., including storm water sewer systems. Depending on the activities and services provided, a portable rock crushing facility may need its own NPDES general permit for direct or indirect discharge. If the facility is located within a city that has an NPDES permit, it may be subject to the city's pretreatment and storm water requirements.
