PART 3 - EXECUTION
3.1 Subgrade
A. Trees, bushes, and a minimum of four inches (4 ") of top soil will be removed from the
site. The area will be graded to the required depth to accommodate the base and
concrete thickness and provide a uniform one percent (1 %) slope at plus or minus one
tenth of a foot (+.l') in one plane. Fills will be placed in six inch (6") layers and will be
compacted to ninety five percent (95%) standard density at optimum moisture. The
contractor will alert the owner of soft spots or structures that could affect the stability of
the slab.
B. The site preparation will be done so as to provide positive drainage away from the play
courts and, if needed, to provide intercepting swales to prevent drainage on to the court.
C. Post-tension courts may be laid on existing asphalt courts only with pre-approved
permission from the City Project Manager.
3.02 Fine Grade
A. The base material shall be placed with automatic laser-regulated equipment capable of
providing a true accurate to plus or minus one-quarter inch(+ 1/4"). The depth of the fine
grade base material shall be sufficient to develop a one-quarter inch (1/4") accuracy.
RFP 8498 Tennis Court Maintenance & Renovation On-Call
3.03 Forming
A. Forms shall be accurately set to the lines and to plus or minus one-quarter inch(+ 1/4")
of finished grades indicated on drawings and be securely staked to prevent settlement or
movement during placement of concrete. Forms shall remain until concrete has taken
final set.
3.04 Tensioning Cables and Anchors
A. Unless specified otherwise by the contractor's structural engineer, cables shall be
supported on chairs and loosely tied two inches (2 ") high at all intersections ( too tightly
tied, tendon friction will increase when tensioning) to prevent vertical and horizontal
movement during concrete placement. Strands shall be places with no greater spacing
than two feet six inches (2'6") wide over 100' and 3 '4" on lengths under 100'. See
drawing details for cable spacing. After the forms are removed and the concrete has set
to a minimum of 2,000 psi the tensioning procedure may be applied approximately one
(1) week later. Each tendon may initially be tensioned to a maximum of eighty percent
(80%) ultimate breaking strength and anchored at a minimum of seventy percent (70%)
ultimate breaking strength.
Ultimate Breaking Strength: 41,300
80%: 33,000
70%: 28,900
B. Post-Tensioning: If strand sheathing is damaged or removed, it is to be repaired by
taping. A maximum of 6" exposed strand is permitted at the anchor. Dead end
anchorages must be power seated. Cables should be laid out in grids no greater in
dimension than that specified by the Contractor's Structural Engineer. Concrete must be
well consolidated, especially in the vicinity of strand anchorages. Strands should be
anchored at 28.9 KIPS, but may be initially stressed at 33 KIPS. A 9" diameter centered
on the strand axis by a 36" length should be allowed for stressing equipment clearance.
The stressing process generates tremendous pressures and extreme care should be
taken to prevent injury from operator error or failure of equipment or materials.
C. Slabs should be designed using acceptable engineering practices in accordance with the
American Concrete Institute Building Code Requirements for reinforced concrete and the
Post-Tensioning Institute's tentative specifications for post-tensioning materials. The soil
condition and plasticity index of the court site should be considered in determining strand
spacing and beam requirements.
D. Unless specified otherwise by the contractor's structural engineer, the cable ends shall
be cut off and cone holes grouted flush with edge of slab. Grout shall be non-shrink
grout.
3.03 Joints
A. Joint locations, if any, shall be specified by the Contractor's Structural Engineer.
B. Single courts may be poured as a monolithic slab, or a metal key way joint or tooled
control joint may be placed at the net line to minimize cracking of the slab due to
shrinkage, prior to stressing the cables.
C. An elastomeric metal construction joint may be placed on the net line if needed. Joints
shall not be installed in the play areas.
RFP 8498 Tennis Court Maintenance & Renovation On-Call
D. Multiple court banks may have an expansion joint between every two courts. Where this
occurs, the cables will be "dead ended" on both sides.
E. For multi-court banks, an accepted alternative expansion joint method would be to
construct a common expansion joint between every two courts with a T-joint method.
The cabling system can be continued through the system to allow for tension to be
applied at the end of the total slab distance.
3.04 Placing and Finishing
A. Fence posts, net posts, sleeves and center anchor should be installed prior to or during
concrete placement. Fencing should be completed prior to surfacing.
B. Concrete should be placed by pumping method.
C. Unless specified otherwise by the Contractor's Structural Engineer, a full court shall be
placed in one (I) continuous operation without intervening joints.
D. The slab will be placed with a sixty foot (60') mechanical screed capable of providing a
surface true to one-eighth inch (1/8") at a I% slope.
E. Concrete should be spread, consolidated, screeded, bull-floated and finished in
accordance with Section 7.2 of ACI (American Concrete Institute) Standard 302,
Recommended Practice for Concrete Floor and Slab Construction.
F. When concrete is sufficiently set to withstand foot pressure and the water sheen has left
the surface, the slab should be uniformly finished by power floating and troweling.
G. The final finish texture should be a medium broom finish unless otherwise specified by
the surface manufacturer. No curing compounds should be used at any time.
3.05 Curing
A. Immediately after finishing, the concrete should be kept continuously moist for 7 days by
covering with polyethylene film or waterproof curing paper, or by sprinkling or ponding or
other acceptable coverings. Curing compounds shall not be used. Curing time should be
in accordance with surfacing system manufacturer's recommendations (must be
compatible with acrylic tennis surfacing material). Timing is critical on all of the above
due to the possibility of disturbing the finished surface.
3.06 Surface Tolerances
A. The finished surface of the court should not vary more than 1/8" (over a nickel) in 10'
when measured in any direction. This is to be determined by flooding the court with
water, allowing it to drain for one hour on a 70 degree or warmer day.

APPENDIX J
Construction, Deconstruction Or Demolition Waste Diversion
This policy applies to waste material generated from the construction,
deconstruction, or demolition of City of Fort Collins facility projects.
Purpose: To divert the maximum amount of building materials from the waste
stream and reduce the demand for new materials - thus decreasing the
environmental impact of providing those materials. Priority is to reuse materials in
new or existing structures. Those materials not suitable for reuse shall be
recycled - as feasible. Sending material to a landfill is a last resort. (Hazardous
material is an exception.) Relocating and using a structure at another site is a
method of reuse.
Background: In the context of physical construction, deconstruction is the
selective dismantlement of building components, specifically for re-use, recycling,
and waste management. It differs from demolition where a site is cleared of its
building by the most expedient means. Deconstruction has also been defined as
“construction in reverse.” The process of dismantling structures is an ancient
activity that has been revived by the growing field of sustainable, green building.
Buildings, like everything, have a life cycle. Deconstruction focuses on giving the
materials within a building a new life once the building as a whole can no longer
continue.
When buildings reach the end of their useful life, they are typically demolished
and hauled to landfills. Building implosions or ‘wrecking-ball’ style demolitions are
relatively inexpensive and offer a quick method of clearing sites for new
structures. On the other hand, these methods create substantial amounts of
waste. Components within old buildings may still be valuable, sometimes more
valuable than at the time the building was constructed. Deconstruction is a
method of harvesting what is commonly considered “waste” and reclaiming it into
useful building material.
A major difference between construction debris and deconstruction/demolition
(D/D) debris is that construction debris tends to be cleaner and more easily
separated. D/D materials typically tend to be from older facilities, so
contaminants such as asbestos, lead based finishes, mercury, and PCB's
complicates there reuse and recycling.
Policies, Procedures, and Guidelines:
1. City project managers are responsible for communicating the policies for
waste diversion to contractors and subcontractors performing construction,
deconstruction & demolition work. Project managers of projects that generate
ATTACHMENT 4
J-2
large amounts of debris and waste material shall work closely with the City’s
Natural Resources Department (NRD) to ensure diversion meets specific City of
Fort Collins goals.
2. For a D/D project, an environmental assessment and proper removal of any
identified hazardous materials is required prior to further work.
3. Contractors and/or project managers must obtain all appropriate permits.
4. Diversion goals: New building construction waste diversion must adhere to the
Leadership in Energy and Environmental Design (LEED) Gold diversion ratings.
Deconstruction and demolition projects should achieve 100% diversion of
materials such as concrete, rock, asphalt, dirt, bricks, and metals and at least
70% diversion of all remaining materials by weight or volume through source
separation of reuse, recyclable or salvageable materials.
5. City’s request for proposals (RFP) and contracts for these projects shall
require the submission of a recycling, reuse, and disposal plan to the project
manager for approval. To measure compliance, the plan shall include tracking of
salvaged, recycled and waste materials be documented on a form similar to
attachment one. Copies of receipts and/or weight tickets may also be required. A
copy of the tracking form shall be provided to Natural Resources Department.
6. City contractors violating the City’s diversion policy may be barred from City of
Fort Collins construction, deconstruction or demolition contracts for a period of
two years.
7. In the event of a natural or other disaster, the diversion goals as stated above
shall apply to any/all disaster relief cleanup efforts unless modified by the Natural
Resources Department.
8. The Natural Resources Department, in concert with the project managers, will
maintain a construction, deconstruction, and demolition waste “best practices”
manual with an annually updated list of recycling and reuse options.
9. A diversion cost analysis will be conducted on larger projects (>$50,000) to
determine if deconstruction is not cost prohibited along with a determination of
project time requirement and if the facility is suitability for deconstruction.

Dust Prevention and Control Manualͷ
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:
(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.
(iii) 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.
(iv) High winds restriction: temporarily halt work activities during high wind events greater than
30 mph if operations would result in off-property transport.
(v) Restrict access: restrict access to the work area to only authorized vehicles and personnel.
Dust Prevention and Control Manualͻ
(b) Additional Best Management Practices: In the event 3.1(a)(i)-(v) 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 disturbed soil surfaces, backfill materials, screenings, and
other dust generating operations as necessary and appropriate considering current weather
conditions, and prevent water used for dust control from entering any public right-of-way,
stormwater drainage facility, or watercourse.
(ii) Wind barrier: construct a fence or other type of wind barrier to prevent wind erosion of top
soils.
(iii) Vegetation: plant vegetation appropriate for retaining soils or creating a wind break.
(iv) Surface roughening: stabilize an active construction area during periods of inactivity or
when vegetation cannot be immediately established.
(v) Cover: install cover materials during periods of inactivity and properly anchor the cover.
(vi) Soil retention: stabilize disturbed or exposed soil surface areas that will be inactive for more
than 30 days or while vegetation is being established.
(c) Additional requirements: Any person, owner, or operator who conducts earthmoving that is a dust
generating activity or source at a construction site or land development project with a lot size equal to
or greater than five (5) acres also shall implement the following measures:
(i) Dust Control Plan: submit a plan that describes all potential sources of fugitive dust and
methods that will be employed to control dust emissions with the development construction
permit application or development review application (see Chapter 4 of this Manual). A copy of
the Dust Control Plan must be onsite at all times and one copy must be provided to all
contractors and operators engaged in dust generating activities at the site.
(ii) Construction sequencing: include sequencing or phasing in the project plan to minimize the
amount of disturbed area at any one time. Sites greater than 25 acres in size may be asked to
provide additional justification, revise the sequencing plan, or include additional best
management practices.
Dust Prevention and Control ManualͳͲ
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
(a) Required Best Management Practices: Any person, owner, or operator who conducts demolition or
renovation 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) Asbestos and lead containing materials: demolition and renovation activities that involve
asbestos or lead containing materials must be conducted in accordance with 2012 International
Building Code (IBC), as adopted by the Code Sec. 5-26 and amended by Code Sec. 5-27 (59)
(amending IBC §3602.1.1) and all other state and local regulations;
(ii) Restrict access: restrict access to the demolition area to only authorized vehicles and
personnel;
(iii) High winds restriction: temporarily halt work activities during high wind events greater than
30 mph if operations would result in off-property transport; and
(iv) 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.
Dust Prevention and Control Manualͳͳ
(b) Additional Best Management Practices: In the event 3.2(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) Wet suppression: apply water to demolished materials or pre-wet materials to be
demolished as necessary. Prevent water used for dust control from entering any public right-of-
way, storm drainage facility, or watercourse.

Dust Prevention and Control Manualͳʹ
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
cannot be immediately established.
Dust Prevention and Control Manualͳ͵
(iv) Stockpile location: locate stockpile at a distance equal to ten times the pile height from
property boundaries that abut residential areas.
(v) Vegetation: seed and mulch any stockpile that will remain inactive for 30 days or more.
(vi) Enclosure: construct a three-sided structure equal to or greater than the height of the pile to
shelter the pile from the predominant winds.
(c) Additional requirements:
(i) Stockpile permit compliance: comply with all conditions and requirements under any
stockpile permit required under the Code or the Land Use Code.
(ii) Erosion control plan compliance: implement and comply with all conditions and
requirements of the “Fort Collins Stormwater Criteria Manual, as adopted in Code Sec. §26-500;
specifically, Volume 3 Chapter 7 “Construction BMPs”. The Stormwater Criteria Manual may

surface roughening, vegetation, silt fence and other control measures.
Dust Prevention and Control ManualͳͶ
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.
Dust Prevention and Control Manualͳͷ
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:

Dust Prevention and Control Manualͳ
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.

Dust Prevention and Control Manualʹͳ
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.

Dust Prevention and Control Manualʹʹ
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-

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.
