(viii)    Spraying the material being transported in a vehicle with a dust suppressant. The frequency of spraying shall be specified in the control program.

(ix)   Restricting the speed of the vehicle which transports the material. The speed of the vehicle shall be specified in the control program.

(4)    The following provision applies to outdoor conveying as a source of fugitive dust: Typical control methods for controlling fugitive emissions resulting from conveying bulk materials may include, but are not limited to, the following:

(a)   Completely enclosing all conveyor belts and equipping them with belt wipers and hoppers of proper size to prevent excessive spills.

(b)    Enclosing transfer points and, if necessary, exhausting them to a baghouse or similar control device at all times when the conveyors are in operation.

(c)   Equipping the conveyor belt with not less than 210-degree enclosures.

(d)  Restricting the speed of conveyor belts. The belt speed shall be specified in the control program.

(e)    Periodically cleaning the conveyor belt to remove the residual material. The frequency of cleaning shall be specified in the control program.

(f)   Minimizing the distance between transfer points. The distance between transfer points shall be specified in the control program.

(g)   Removing the spilled material from the ground under conveyors. The frequency of removal shall be specified in the control program.

(5)   The following provisions apply to roads and lots as sources of fugitive dust:

(a)   Roads and lots which are located within industrial, commercial, and government- owned facilities and which meet the following 2 conditions are not subject to the requirement of submitting a fugitive dust control program:

(i)   The traffic volume is less than 10 vehicles per day on a monthly average.

(ii)   The lots are less than 500 square meters (5,382 feet2) in area.

(b)   Typical control methods for controlling fugitive emissions resulting from roads and lots located within industrial, commercial, and government-owned facilities may include, but are not limited to, the following:

(i)   Paving roads and parking lots with a hard material, such as concrete, asphalt, or an equivalent which is approved by the department.

(ii)    Mechanically cleaning paved surfaces by vacuum sweeping, wet sweep-ing, or flushing.  The frequency of cleaning shall be specified in the control program.

(iv)    Treating the roads and lots with oil or a dust-suppressant compound which is approved by the department. The frequency of application shall be specified in the control program.

(v)   Periodically maintaining off-road surfaces with gravel where trucks have frequent access.  The frequency of maintenance shall be specified in the control program.

(6)    The following provisions apply to inactive storage piles as sources of fugitive dust:

(a)   Inactive storage piles that are less than or equal to 500 cubic meters (654 yards3) in volume are not subject to the requirement of submit-ting a fugitive dust control program.

(b)   Typical control methods for controlling fugitive emissions resulting from inactive storage piles may include, but are not limited to, the following:
