2.0 Fugitive Dust and the Problems it Causes
2.1 What is Fugitive Dust, Generally?
Dust, also known as particulate matter, is made up of solid particles in the air that consist primarily of
dirt and soil but can also contain ash, soot, salts, pollen, heavy metals, asbestos, pesticides, and other
materials. “Fugitive” dust means particulate matter that has become airborne by wind or human
activities and has not been emitted from a stack, chimney, or vent. The Colorado Department of Public
Health and Environment (CDPHE) estimates that more than 4,300 tons of particulate matter are emitted
into the air in Larimer County annually. The primary sources of this particulate matter include
construction activities, paved and unpaved roads, and agricultural operations.
The quantity of dust emitted from a particular activity or area and the materials in it can depend on the
soil type (sand, clay, silt), moisture content (dry or damp), local wind speed, and the current or past uses
of the site (industrial, farming, construction).
2.2 Why is the City Addressing Fugitive Dust?
Colorado state air regulations and Larimer County air quality standards generally require owners and
operators of dust generating activities or sources to use all available and practical methods that are
technologically feasible and economically reasonable in order to prevent fugitive dust emissions.
However, state regulations and permitting requirements typically apply to larger stationary sources
rather than to activities that generate dust. Larimer County fugitive dust standards apply only to land
development.
Although state and county requirements apply to many construction activities, they do not address
many sources of dust emissions and City code compliance officers do not have authority to enforce state
or county regulations. Fort Collins is experiencing rapid growth and development that has contributed
to local man-made dust emissions. The City has established Chapter 12, Article X of the Code (§§12-150-
12-159) to address dust generating activities and sources that negatively impact citizens in Fort Collins.

Dust Prevention and Control Manual
2.3 Health and Environmental Effects
Dust particles are very small and can be easily inhaled. They can
enter the respiratory system and increase susceptibility to respiratory
infections, and aggravate cardio-pulmonary disease. Even short-term
exposure to dust can cause wheezing, asthma attacks and allergic
reactions, and may cause increases in hospital admissions and
emergency department visits for heart and lung related diseases.
Fugitive dust emissions can cause significant environmental impacts as well as health effects. When
dust from wind erosion or human activity deposits out of the air, it may impact vegetation, adversely
affect nearby soils and waterways, and cause damage to cultural resources. Wind erosion can result in
the loss of valuable top soil, reduce crop yields, and stunt plant growth.
According to the Environmental Protection Agency (EPA), studies have linked particulate matter
exposure to health problems and environmental impacts such as:
•Health Impacts:
o Irritation of the airways, coughing, and difficulty breathing
o Reduced lung function and lung cancer
o Aggravated asthma and chronic bronchitis
o Irregular heartbeat and increases in heart attacks
•Environmental Impacts:
o Haze and reduced visibility
o Reduced levels of nutrients in soil
2.4 Nuisance and Aesthetics
Dust, dirt and debris that become airborne eventually settle back down to
the surface. How far it travels and where it gets deposited depends on the
size and type of the particles as well as wind speed and direction. When this
material settles, it can be deposited on homes, cars, lawns, pools and ponds,
and other property. The small particles can get trapped in machinery and
electronics causing abrasion, corrosion, and malfunctions. The deposited
dust can damage painted surfaces, clog filtration systems, stain materials and
cause other expensive clean-up projects.
2.5 Safety Hazard and Visibility
Blowing dust can be a safety hazard at construction sites and on roads and
highways. Dust can obstruct visibility and can cause accidents between
vehicles and bikes, pedestrians, or site workers. Dust plumes can also
decrease visibility across a natural area or scenic vistas. The “brown cloud”,
often visible along the Front Range during the winter months, and the
brilliant red sunsets that occur are often caused by particulate matter and
other pollutants in the air.

Dust Prevention and Control Manual
3.0 Best Management Practices
This Manual describes established best management practices for controlling dust emissions that are
practical and used in common practice to prevent or mitigate impacts to air quality from dust generating
activities and sources occurring within Fort Collins. The objective of the dust control measures included
in this Manual is to reduce dust emissions from human activities and to prevent those emissions from
impacting others and is based on the following principles:
Prevent – avoid creating dust emissions through good project planning and modifying or
replacing dust generating activities.
Minimize – reduce dust emissions with methods that capture, collect, or contain emissions.
Mitigate – when preventing fugitive dust or minimizing the impacts are not feasible, the
Manual provides specific measures to mitigate dust.
More specifically, the Manual establishes the following procedures for each dust generating activity
outlined in this Chapter:
1. 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.
2. Additional Best Management Practices – this section includes additional measures if the
required best management practices are ineffective at preventing off-property transport of
particulate matter. At least one of the additional best management practices outlined in the
Manual must be implemented on the site to be in compliance with the Manual and Code.
3. Additional Requirements – When applicable, additional measures are also required, e.g., a dust
control plan when project sites are over 5 acres in size.
The Dust Prevention and Control Checklist included on page 31 of this Manual provides a “quick guide”
to dust control BMPs covered in the following sections of the Manual.

Dust Prevention and Control Manualͺ
3.1 Earthmoving Activities
Above: This figure illustrates earthmoving, which is an activity that can generate dust.
Dust emissions from earthmoving activities depend on the type and extent of activity being conducted,
the amount of exposed surface area, wind conditions, and soil type and moisture content, including:
x Site preparation (clearing, grubbing, scraping)
x Road construction
x Grading and overlot grading
x Excavating, trenching, backfilling and compacting
x Loading and unloading dirt, soil, gravel, or other earth materials
x Dumping of dirt, soil, gravel, or other earth materials into trucks, piles, or receptacles
x Screening of dirt, soil, gravel, or other earth materials
Best Management Practices to Control Dust
(a) 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:

3.2 Demolition and Renovation
Above: This photo illustrates restricting access (a required best management practice) and a wind barrier
(an additional best management practice) for demolition and renovation activities.
Dust generated from demolition activities may contain significant levels of silica, lead, asbestos, and
particulate matter. Inhalation of silica and asbestos is known to cause lung cancer, and exposure to
even small quantities of lead dust can result in harm to children and the unborn.
In addition to complying with the dust control measures below, any person engaged in demolition or
renovation projects must comply with applicable state and federal regulations for asbestos and lead
containing materials and notification and inspection requirements under the State of Colorado Air
Quality Control Commission's Regulation No. 8, Part B Control of Hazardous Air pollutants.
Best Management Practices to Control Dust

3.3 Stockpiles
Above: This photo illustrates wet suppression, an additional best management practice for stockpiles.
Stockpiles are used for both temporary and long-term storage of soil, fill dirt, sand, aggregate,
woodchips, mulch, asphalt and other industrial feedstock, construction and landscaping materials.
Fugitive dust can be emitted from stockpiles while working the active face of the pile or when wind
blows across the pile. The quantity of emissions depends on pile height and exposure to wind, moisture
content and particle size of the pile material, surface roughness of the pile, and frequency of pile
disturbance.
Best Management Practices to Control Dust
(a) 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:
(i) Minimize drop height: Drivers and operators shall unload truck beds and loader or excavator
buckets slowly, and minimize drop height of materials to the lowest height possible, including
screening operations.
(b) Additional Best Management Practices: In the event 3.3(a)(i) is ineffective to prevent off-property
transport, the person, owner, or operator shall use at least one of the following best management
practices:
(i) Wet suppression: Apply water to the active face when working the pile or to the entire pile
during periods of inactivity. Prevent water used for dust control from entering any public right-
of-way, storm drainage facility, or watercourse.
(ii) Cover: install cover materials during periods of inactivity and anchor the cover.
(iii) Surface roughening: stabilize a stockpile during periods of inactivity or when vegetation

3.4 Street Sweeping
Left: This figure illustrates the use
of a wet suppression and vacuum
system, an additional best
management practice for street
sweeping.
Street sweeping is an effective method for removing dirt and debris from streets and preventing it from
entering storm drains or becoming airborne. Regenerative air sweepers and mechanical sweepers with
water spray can also be effective at removing particulate matter from hard surfaces.
Best Management Practices to Control Dust
(a) 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.
(b) Additional Best Management Practices: In the event 3.4(a)(i) is ineffective to prevent off-property
transport, the person, owner, or operator shall use at least one of the following best management
practices:
(i) Wet suppression: use a light spray of water or wetting agent applied directly to work area or
use equipment with water spray system while operating sweeper or power broom. Prevent
water used for dust control from entering any storm drainage facility or watercourse.
(ii) Vacuum system: use sweeper or power broom equipped with a vacuum collection and
filtration system.
(iii) Other method: use any other method to control dust emissions that has a demonstrated
particulate matter control efficiency of 80 percent or more.

3.5 Track-out / Carry-out
Above: This figure illustrates an installed grate (left) and a gravel bed (right), both of which are
additional best management practices associated with track-out/carry-out.
Mud, dirt, and other debris can be carried from a site on the wheels or undercarriage of equipment and
vehicles onto public roads. When this material dries, it can become airborne by wind activity or when
other vehicles travel on it. This is a health concern and can cause visibility issues and safety hazards.
Best Management Practices to Control Dust
(a) Required Best Management Practices: Any owner or operator of any operation that has the
potential to result in track-out of mud, dirt, dust, or debris on public roads and rights-of-way and whose
operation is a dust generating activity or source shall implement the following best management
practices to prevent off-property transport of fugitive dust emissions:
(i) Contracts and standards: comply with track-out prevention requirements and construction
best management practices as set forth in the Code, City regulations or policies, as specified in
applicable contract documents, and as set forth in the Fort Collins Stormwater Criteria Manual.
(ii) Remove deposition: promptly remove any deposition that occurs on public roads or rights-
of-way as a result of the owner’s or operator’s operations. Avoid over-watering and prevent
runoff into any storm drainage facility or watercourse.
(b) Additional Best Management Practices: In the event 3.5(a)(i)-(ii) are ineffective to prevent off-
property transport, the person, owner, or operator shall use at least one of the following best
management practices:
(i) Install rails, pipes, grate, or similar track-out control device.
(ii) Install a gravel bed track-out apron that extends at least 50 feet from the intersection with a
public road or right-of-way.
(iii) Install gravel bed track-out apron with steel cattle guard or concrete wash rack.
(iv) Install and utilize on-site vehicle and equipment washing station.
(v) Install a paved surface that extends at least 100 feet from the intersection with a public road
or right-of-way.

3.6 Bulk Materials Transport
Above: This figure illustrates covered loads, a required best management practice for bulk materials
transport.
Haul trucks are used to move bulk materials, such as dirt, rock, demolition debris, or mulch to and from
construction sites, material suppliers and storage yards. Dust emissions from haul trucks, if
uncontrolled, can be a safety hazard by impairing visibility or by depositing debris on roads, pedestrians,
bicyclists, or other vehicles.
Best Management Practices to Control Dust
(a) 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:
(i) Cover Loads: Loads shall be completely covered or all material enclosed in a manner that
prevents the material from blowing, dropping, sifting, leaking, or otherwise escaping from the
vehicle. This includes the covering of hot asphalt and asphalt patching material with a tarp or
other impermeable material.
(ii) Minimize drop height: Drivers and operators shall load and unload truck beds and loader or
excavator buckets slowly, and minimize drop height of materials to the lowest height possible,
including screening operations.

3.7 Unpaved Roads and Haul Roads
Left: This figure illustrates
surface improvements on an
unpaved road, an additional
best management practice.
Road dust from unpaved roads is caused by particles lifted by and dropped from rolling wheels traveling
on the road surface and from wind blowing across the road surface. Road dust can aggravate heart and
lung conditions as well as cause safety issues such as decreased driver visibility and other safety hazards.
Best Management Practices to Control Dust
(a) 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.
(b) Additional Best Management Practices: In the event 3.7(a)(i)-(ii) are ineffective to prevent off-
property transport, the person, owner, or operator shall use at least one of the following best
management practices:
(i) Wet suppression: apply water to unpaved road surface as necessary and appropriate
considering current weather conditions, and prevent water used for dust control from entering
any public right-of-way, storm drainage facility, or watercourse.
(ii) Surface improvements: install gravel or similar materials with sufficient depth to reduce dust
or pave high traffic areas.
(iii) Access road location: locate site access roads away from residential or other populated
areas.

3.9 Open Areas and Vacant Lots
Left: This photo
represents adding
vegetation by
hydroseeding,
which is one
measure to comply
with the Manual.
Open areas are typically not a significant source of wind-blown dust emissions if the coverage of
vegetation is sufficient or soil crusts are intact. However, if soils in open areas are disturbed by vehicle
traffic, off-highway vehicle use, bicycling or grazing, or if they have become overpopulated by prairie
dogs, dust emissions can become a problem.
Best Management Practices to Control Dust
(a) 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.
(iii) Surface roughening: stabilize an exposed area during periods of inactivity or when
vegetation cannot be immediately established.
(iv) Soil retention: stabilize disturbed or exposed soil surface areas that will be inactive for more
than 30 days or while vegetation is being established, using mulch, compost, soil mats, or other
methods.
(v) Wet suppression: apply water to disturbed soil surfaces as necessary and appropriate
considering current weather to prevent off-property transport of fugitive dust emissions.
Prevent water used for dust control from entering any public right-of-way, storm drainage
facility, or watercourse.
(vi) Wind barrier: construct a fence or other type of wind barrier to prevent wind erosion of top
soils.

3.10 Saw Cutting and Grinding
Above: This photo illustrates concrete cutting and how the activity can generate dust.
Cutting and grinding of asphalt, concrete and other masonry materials can be a significant short-term
source of fugitive dust that may expose workers and the public to crystalline silica. Inhalation of silica
can cause lung disease known as silicosis and has been linked to other diseases such as tuberculosis and
lung cancer. Using additional best management practices during cutting and grinding operations can
significantly reduce dust emissions.
Best Management Practices to Control Dust
(a) 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 Collins Stormwater
Criteria Manual or contract documents and specifications.

Dust Prevention and Control Manualʹ͵
(b) Additional Best Management Practices: In the event 3.10(a)(i)-(iv) are ineffective to prevent off-
property transport, the person, owner, or operator shall use at least one of the following best
management practices:
(i) On-tool local exhaust ventilation: use a tool-mounted dust capture and collection system.
(ii) On-tool wet suppression: use a tool-mounted water application system.
(iii) Vacuuming: use a vacuum equipped with a HEPA filter simultaneously with cutting or
grinding operations.
(iv) Wet suppression: use a water sprayer or hose simultaneously with cutting or grinding
operations.
(v) Enclosure: conduct cutting or grinding within an enclosure with a dust collection system or
temporary tenting over the work area.
Above: These photos illustrate how dust generated from cutting can be minimized by applying on-tool
wet suppression, an additional best management practice associated with saw cutting and grinding.

3.11 Abrasive Blasting
Above: This photo illustrates abrasive blasting without dust mitigation in place.
Abrasive blasting is used to smooth rough surfaces; roughen smooth surfaces; and remove paint, dirt,
grease, and other coatings from surfaces. Abrasive blasting media may consist of sand; glass, plastic or
metal beads; aluminum oxide; corn cobs; or other materials. Abrasive blasting typically generates a
significant amount of fugitive dust if not controlled. The material removed during abrasive blasting can
become airborne and may contain silica, lead, cadmium or other byproducts removed from the surface
being blasted.*
Best Management Practices to Control Dust
(a) Required Best Management Practices: Any person, owner, or operator who conducts outdoor
abrasive blasting or indoor abrasive blasting with uncontrolled emissions vented to the outside 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) 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.
(b) Additional Best Management Practices: In the event 3.11(a)(i)-(iv) are ineffective to prevent off-
property transport, the person, owner, or operator shall use at least one of the following best
management practices:
(i) Enclosure: conduct abrasive blasting within an enclosure with a dust collection system or
temporary tenting over the work area.
BID 8527 Concrete Trip Hazard Removal Project Page 42 of 56
Dust Prevention and Control Manualʹͷ
(ii) Wet suppression blasting: use one of several available methods that mix water with the
abrasive media or air during blasting operations.
(iii) Vacuum blasting: conduct air-based blasting that uses a nozzle attachment with negative air
pressure to capture dust.
(iv) Abrasive media: select less toxic, lower dust-generating blasting media.
* Blasting on surfaces that contain lead paint or wastes from sand blasting that contain hazardous materials may be subject
to additional state and federal requirements.

3.12 Mechanical Blowing
Above: This photo illustrates mechanical blowing without dust mitigation in place.
Mechanical blowers are commonly used to move dirt, sand, leaves, grass clippings and other
landscaping debris to a central location for easier pick-up and removal. Mechanical blowing with a leaf
blower can be a significant source of fugitive dust in some situations and can create nuisance conditions
and cause health effects for sensitive individuals. Mechanical blowing can re-suspend dust particles that
contain allergens, pollens, and molds, as well as pesticides, fecal contaminants, and toxic metals causing
allergic reactions, asthma attacks and exacerbating other respiratory illnesses.
Best Management Practices to Control Dust
(a) 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.
(b) Additional Best Management Practices: In the event 3.11(a)(i)-(iii) are ineffective to prevent off-
property transport, the person, owner, or operator shall use at least one of the following best
management practices:
(i) Alternative method: use an alternative such as a rake, broom, shovel, manually push
sweeper or a vacuum machine equipped with a filtration system.
(ii) Prevent impact: do not blow dust and debris off-property or in close proximity to people,
animals, open windows, air intakes, or onto adjacent property, public right-of-way, storm
drainage facility, or watercourse.
BID 8527 Concrete Trip Hazard Removal Project Page 44 of 56
Dust Prevention and Control Manualʹ
(iii) Minimize use on dirt: minimize the use of mechanical blower on unpaved surfaces, road
shoulders, or loose dirt.
(iv) Wet suppression: use a light spray of water, as necessary and appropriate considering
current weather conditions, to dampen dusty work areas. Prevent water, dirt, and debris from
entering any storm drainage facility, or watercourse.
(v) Remove debris: remove and properly dispose of blown material immediately.
