Required Best Management Practices. Any person, owner, or operator that cuts or grinds asphalt, concrete, brick, tile, stone, or other masonry materials and whose operations are a dust generating activity or source shall use the following best management practices to prevent off-property transport of fugitive dust emissions:
(i) Restrict access: prevent the public from entering the area where dust emissions occur.
(ii) High winds restriction: temporarily halt work activities during high wind events greater than 30 mph if operations would result in off-property transport.
(iii) Equipment and work area clean up: use wet wiping, wet sweeping, or vacuuming with HEPA filtration for equipment and work area clean up and do not cause dust to become airborne during clean up.
(iv) Slurry clean up: prevent water used for dust control or clean up from entering any public right-of-way, storm drainage facility, or watercourse by using containment, vacuuming, absorption, or other method to remove the slurry, and dispose of slurry and containment materials properly. Follow additional procedures prescribed in the Fort Xxxxxxx Stormwater Criteria Manual or contract documents and specifications.
Required Best Management Practices this section includes the specific measures that are required to be implemented if the dust generating activity is occurring. For example, high wind restrictions (temporarily halting work when wind speeds exceed 30 mph) are required best management practices for earthmoving, demolition/renovation, saw cutting or grind, abrasive blasting, and leaf blowing.
Required Best Management Practices. Any person, owner, or operator who conducts earthmoving that is a dust generating activity or source shall implement the following best management practices to prevent off-property transport of fugitive dust emissions:
(i) Minimize disturbed area: plan the project or activity so that the minimum amount of disturbed soil or surface area is exposed to wind or vehicle traffic at any one time.
(ii) Reduce vehicle speeds: establish a maximum speed limit or install traffic calming devices to reduce speeds to a rate to mitigate off-property transport of dust entrained by vehicles.
Required Best Management Practices. Any owner or operator of a stockpile that is a dust generating activity or source shall implement the following best management practices to prevent off property transport of fugitive dust emissions:
Required Best Management Practices. Any owner or operator that conducts sweeping operations or services on paved or concrete roads, parking lots, rights-of-way, pedestrian ways, plazas or other solid surfaces, and whose operations are a dust generating activity or source shall implement the following best management practices to prevent off-property transport of fugitive dust emissions:
(i) Uncontrolled sweeping prohibited: the use of rotary brushes, power brooms, or other mechanical sweeping for the removal of dust, dirt, mud, or other debris from a paved public road, right-of-way, or parking lot without the use of water, vacuum system with filtration, or other equivalent dust control method is prohibited. Mechanical or manual sweeping that occurs between lifts of asphalt paving operations or due to preparation for pavement markings are excluded from this prohibition, due to engineering requirements associated with these operations.
Required Best Management Practices. Any owner or operator of a dust generating activity or source for which vehicles used to transport bulk materials to and from a site within the City on a public or private road or on a public right-of-way shall prevent off-vehicle transport of fugitive dust emissions. To prevent off-vehicle transport of fugitive dust to and from the site, the owner or operator shall implement the following measures:
Required Best Management Practices. Any owner or operator of an unpaved road located on a construction site greater than five acres on private property or an unpaved road used as a public right- of-way shall implement the following best management practices to prevent off-property transport of fugitive dust emissions:
(i) Reduce vehicle speeds: establish a maximum speed limit or install traffic calming devices to reduce speeds to a rate that prevents off-property transport of dust entrained by vehicles.
(ii) Restrict access: restrict travel on unpaved roads by limiting access to only authorized vehicle use.
Required Best Management Practices. An owner or operator of a paved parking lot greater than one-half acre and shall use at least one of the following best management practices to prevent off- property transport of fugitive dust emissions.
(i) Maintenance: repair potholes and cracks and maintain surface improvements.
(ii) Mechanical sweeping: Sweep lot with a vacuum sweeper and light water spray as necessary to remove dirt and debris. Avoid overwatering and prevent runoff from entering any public right-of-way, storm drainage facility, or watercourse.
(iii) Reduce vehicle speeds: establish a maximum speed limit or install traffic calming devices to reduce speeds to a rate that prevents off-property transport of dust entrained by vehicles.
(iv) Restrict access: restrict travel in parking lots to only those vehicles with essential duties and limit access to hours of operation or specific events.
Required Best Management Practices. Any owner or operator of an open area greater than one-half acre shall use at least one of the following best management practices to stabilize disturbed or exposed soil surface areas that are intended to or remain exposed for 30 days or more and to prevent off- property transport of fugitive dust emissions:
(i) Vegetation: plant vegetation appropriate for retaining soils or creating a wind break.
(ii) Cover: install cover materials over exposed areas during periods of inactivity and properly anchor the cover.
Required Best Management Practices. Any person, owner, or operator who operates a mechanical leaf blower (gas, electric, or battery-powered) in a manner that is a dust generating activity or source shall use the following best management practices as necessary to prevent off-property transport of fugitive dust emissions
(i) Low speed: use the lowest speed appropriate for the task and equipment.
(ii) Operation: use the full length of the blow tube and place the nozzle as close to the ground as possible.
(iii) High winds restriction: temporarily halt work activities during high wind events greater than 30 mph if operations would result in off-property transport.
