Rule 316 Resources

Rule 316 establishes emission limitations and requires the implementation of process controls and fugitive dust control measures for nonmetallic mineral processing plants, asphaltic concrete plants, concrete plants and/or bagging operations, and raw material storage and distribution to support these facilities.

For a comprehensive overview of Rule 316 and how it may apply to your activities, see the Rule 316 Handbook. Some additional topics are addressed below. Permit applications are available on our forms and applications page, and the dust control plan form and operations and maintenance (O&M) plan are also available here. If you have any questions or need assistance in completing any of these documents, please call (602) 506-6010.

Screens

Is a screen that removes oversize aggregate at an asphaltic concrete batch plant subject to the moisture testing requirements in Section 301?

Yes. All screening processes are subject to Rule 316, Section 301. Therefore, any screening process located at an asphaltic concrete batch plant will also be subject to Rule 316, Section 301 requirements for screening including the requirements to maintain minimum moisture content and conduct moisture testing.

On-Site Traffic

Several plants find that flood control structures prevent them from laying a full 1/4 mile of paved roadway between the rumble grate and the paved area accessible to the public. If the plants are just a little short of the 1/4 mile, what can they do?

The owners/operators may submit a request to the control officer for approval of alternative control measure pursuant to Rule 316, Section 307 consisting of the almost 1/4 mile of paved roadway and an added control to compensate for the shortfall in paving. (e.g., include an additional rumble grate somewhere along the road or add a grizzly so that the truck wheels do not contact dirt crossing the flood control structure.)

Submissions to the control officer may be sent to 1001 N. Central Ave., Suite 400, Phoenix, AZ 85004.

The batch plants at my facility are located in the pit. Am I still required to maintain a cohesive hard surface on the roads serving the asphaltic concrete batch plant and concrete batch plant loading areas

Yes. Rule 316, Section 307.4(a) requires all batch trucks and material delivery trucks remain on roads with paved surfaces or cohesive hard surfaces.

An aggregate delivery truck only supplies the batch plants onsite. However, the truck must go through the scales before delivering the aggregate. Does this truck have to remain on a paved or cohesive hard surface?

Rule 316, Section 307.4(b) provides a limited exemption for the aggregate delivery truck to leave the paved or cohesive hard surface to drive to and return from the aggregate loading area. Otherwise the truck is required to remain on paved roads or cohesive hard surfaces designated for batch trucks and material delivery trucks or for vehicular travel in the permanent areas of the site. The rule assumes that stockpiles shrink, expand or are re-located so that the aggregate loading area will not be a permanent area of the site.

Trackout

My facility has pavement (concrete) throughout the entire site. Do I have to install a rumble grate?

Yes. See Rule 316, Section 307.6(c) for a list of exemptions from the wheel washer requirements. Several facilities have installed rumble grates with ramps.

A facility exits onto an unpaved public road. What trackout control requirements apply?

Since the area accessible to the public is unpaved, no trackout control device is required. However, the facility must still comply with the requirement to maintain a hard cohesive surface or paved road on all on-site roads in the permanent areas of the site and on all roads on which batch trucks and material delivery trucks drive.

Subcontractor Registration

Is a company that owns or operates asphalt delivery trucks, ready-mix delivery trucks, and delivery trucks that haul heavy rock to construction sites required to be registered under the Subcontractor Registration Program?

Although the types of trucks listed above are not specifically identified in the dust generating operation definition, these types of trucks use staging areas, parking areas, material storage areas, or access routes to and from a site, which is identified as a dust-generating operation in the definition. Therefore, a company that owns or operates asphalt delivery trucks, ready-mix delivery trucks, and delivery trucks that haul heavy rock must be registered under the Subcontractor Registration Program.

The sole intent of the Program is for owners, contractors, subcontractors, and suppliers, familiar with their business practices, to mitigate dust or manage a site in their area of expertise. Information on the Subcontractor Registration Program including the application form and instructions can be found on the Department's website at: www.maricopa.gov/aq/divisions/compliance/dust/subcontractorRegistration.aspx
