(A) Owner/operators will be responsible for dust control on all gravel roads utilized by trucks hauling to or from the permitted mineral extraction facility. Dust control will be required when conditions warrant it and the number of one-way truck trips from the natural resource extraction site exceed three per hour. The city reserves the right to require dust control on any haul route within the city or those bordering the city.
(B) An owner/operator shall sufficiently prevent or clean up carryout and trackout on paved public roads or the paved shoulders of a paved public road. The use of blower devices, or dry rotary brushes or brooms for removal of carryout and trackout on public roads is expressly prohibited. Flushing with water may be utilized if curbs or gutters are not present and where the use of water will not result as a source of trackout material or result in adverse impacts on storm water drainage systems or violate any National Pollutant Discharge Elimination System permit program. Trackout-control devices are highly encouraged and may be required as a condition of receiving a permit.
(C) The city shall require dust control on the extraction site when it is determined that airborne dust from extraction areas, stockpiles or internal roadways creates a public nuisance or otherwise adversely impacts surrounding lands. Remedies to dust control may include watering, berming, landscaping and enclosures for processing equipment, and any other means deemed necessary by the city.
(D) All activities on the subject property with the potential to impact air quality will be conducted in a manner consistent with operating permits issued by state and federal agencies. The Planning Commission may require other standards it deems reasonably necessary.
