Wait 30 minutes and check for any areas that have sunk and need to be topped off. I.e.
Sinkers.
Clean area of debris left over from the strike off and preparation.
SURFACE PREPARATION – CHIP SEAL
Chip Seal surface preparation shall meet the aforementioned general requirements.
SURFACE PREPARATION – SLURRY SEAL
In addition to Slurry Seal surface preparation meeting the surface preparation general requirements, Slurry Seal
being placed over a surface that has been cleaned of oil spots shall require an approved primer application or other
approved process for mitigating potential de-lamination.
If the Slurry Seal is being placed over a brick or concrete surface, a highly absorbent asphalt surface, areas
subjected to dusty conditions or over a surface where the aggregate has become exposed and is polished and slick,
a one part emulsion, three part water tack coat of the same emulsion type and grade as specified for the slurry is
recommended. This can be applied with an asphalt distributor. The normal application rate is 0.05 to 0.15 gallons
of the diluted emulsion per square yard of surface (0.23 to 0.70 liters per square meter). The Engineer will have
final authority to determine if tack coat is required and the rate at which it shall be applied.
SURFACE PREPARATION – CAPE SEAL
Cape Seal shall meet the general requirements for surface preparation above.
Subsection 409.07 – Applying Asphalt Material - and 409.08 – Application of Cover Coat Material - shall include the
following:
Ensuring proper spread rates and material proportions is the sole responsibility of the Contractor's.
The Owner will continually be checking quantities using run sheets. The Contractor is encouraged to also check
quantities with run sheets to avoid the penalties described herein. Yield estimates with supporting documentation
from the metering devices and material delivery tickets will be provided by the Contractor daily.
The seal coat shall be applied to alternating streets to provide sufficient public parking for those residents living
on streets which have been closed. Traffic will not be allowed on the newly placed bituminous material until, in
the opinion of the Engineer, the bituminous material has sufficiently set and bonded to prevent damage by
vehicular traffic. Areas which are subject to an increased rate of sharp turning vehicles may require additional
time to allow for a more complete cure of the surface application to prevent damage. Street closures shall be
opened as soon as the material has sufficiently set and bonded.
Manholes and valves on streets to be slurry sealed shall be clean when the work is completed. They shall be
covered in a suitable manner prior to sealing, and the covering shall be removed immediately after the street is
sealed. The Contractor shall submit the method for protecting manholes and valves to the Engineer for approval at
least two weeks prior to commencement of work. After sealing, the Contractor shall verify accessibility to
manholes and valves to the satisfaction of the Engineer at the end of each day. Manholes and valves shall be
marked by the Contractor prior to placing the slurry to insure each one is located and can be found after slurry
sealing.
The Contractor is solely responsible for finding and using suitable stockpile locations. The Owner shall be
allowed access to the stockpile locations at all times. No portion of the right of way may be used for storage of
materials or equipment. Materials shall be stored in an area to prevent water saturation and contamination of
stockpiled aggregates. On-site emulsion tanks shall be empty and cleaned of all residual asphalt prior to delivery

material deliveries. Tests may be run on the aggregate and emulsion. Test results will be compared to the
specifications. The Engineer shall notify the Contractor immediately if any test fails to meet the specifications.
Frequency of assurance testing will be at the direction of the Engineer. Noncompliance of materials shall be basis
for rejection. It is the responsibility of the Contractor, at his own expense, to prove to the Engineer that the
conditions have been corrected before work may continue.
APPLICATION – CHIP SEAL
Chip Seal surface treatments shall be installed as a Chip Seal (one layer) or a Double Chip Seal (two layer)
installation.
The surface aggregate size shall be 1/4” on residential streets and 3/8” on collector and arterial streets.
The aggregate and CRS-2P application rates for a Chip Seal treatment shall be in accordance with the following:
CHIP SEAL APPLICATION TABLE (one layer)

Emulsion Application
REVISION OF SECTION 409
SEAL COAT
22
Bituminous material shall be applied by means of a pressure distributor in a uniform, continuous spread over the
section to be treated and within the temperature range of 160 -185º F. The distributor shall be moving forward at
the proper application speed at the time the spray bar is opened. Where multiple passes are required to complete
the full width, the four inches adjacent to the second pass may be left with fifty percent coverage so that the next
pass will complete the full application rate specified.
The nozzle angle and bar height shall be set to provide one hundred percent (100) of double coverage in a single
pass. A strip of roofing paper at least three (3) feet in width and with a length equal to that of the spray bar of the
distributor plus one (1) foot shall be used at the beginning of each spread. If the cut-off is not positive, the use of
paper shall be required at the end of each spread. The paper shall be disposed of in a lawful manner. Any skipped
areas or deficiencies shall be corrected. Junctions of spreads shall be carefully made to assure a smooth riding
surface.
The length of spread of bituminous material shall not be in excess of that which trucks loaded with cover coat
material can immediately cover.
The spread of bituminous material shall not be more than four (4) inches wider than the width covered with
aggregate from the spreading device and shall not spread onto the concrete, gutter, or crosspan. The Contractor
shall use roofing paper or some other approved means of concrete crosspan protection to eliminate emulsion spray
on concrete
Under no circumstances shall operations proceed in such a manner that the bituminous material be allowed to
chill, set up, dry, or otherwise impair retention of the aggregate. Application rates shall be sufficient to prevent
streaked appearance in the surface.
The distributor, when not spreading, shall be parked so that the spray bar or mechanism does not drip bituminous
materials onto the surface of the street, gutters or private property. During all applications, the surface of adjacent
structures shall be protected in such a manner as to prevent their being spattered or marred. Any areas inaccessible
to the distributor shall be sprayed by hand. All sidewalks, gutters or other surfaces where spatter is excessive, in
the opinion of the Engineer, shall be immediately cleaned.
Aggregate Application
Immediately following the application of bituminous material, aggregate cover material shall be spread in
quantities as designated. Spreading shall be accomplished in such a manner that the tires of the trucks or aggregate
spreader at no time contact the uncovered and newly applied bituminous material.
If directed by the Engineer, the cover coat material shall be moistened with water to eliminate or reduce the dust
coating of the aggregate; however, excess dust will be a cause for rejection of the aggregate. Immediately after the
cover coat is spread, any deficient areas shall be covered by additional material.
Rolling
Rolling shall proceed in a longitudinal direction, beginning at the outer edges of application and working toward
the center. Each pass shall overlap the previous pass by one-half of the width of the front wheel or roll. There shall
be a minimum of three (3) passes with the pneumatic-tired rollers over the entire surface prior to moving ahead.
One pass will be considered the number of trips to cover the entire surface from one side of the street to the other
and for the length being worked. The first rolling of the aggregate shall be made before the asphalt emulsion
breaks (roller shall complete the first rolling within approximately two and one-half (2 ½) minutes of the emulsion
spray application). In no event shall traffic be allowed on the treated surface until all rolling has been completed.
The aggregate shall not be applied in such a thickness as to cause blanketing. At no time shall the rollers travel
more than ten miles per hour.
REVISION OF SECTION 409
SEAL COAT
23
Sweeping
After the application of the cover coat material the surface shall be lightly broomed or otherwise maintained as
directed by the Engineer, for a period of three to four days. Maintenance of the surface shall include the
distribution of cover coat material over the surface to absorb any free bituminous material and cover any area
deficient in cover coat material. In those areas requiring additional cover coat material, the surface shall be rolled
with a rubber-tired roller to embed the aggregate in the bituminous material. The maintenance shall be conducted
so as not to displace imbedded material. At the proper time, as determined by the Engineer, all excess cover coat
material shall be removed. Excess aggregate that is clean may be stockpiled and re-used in subsequent locations at
the discretion of the Engineer. The Engineer may reject aggregate that has been previously applied upon visual
observation of the stockpile.
Clean up
Emulsion sprayed on concrete crosspans will require removal by approved methods at the Contractors expense.
All material swept or blown onto sidewalks, all trash, all discarded chip seal material or other construction debris
shall be collected on a daily basis, removed from the site, and disposed of to a site approved by the Engineer.
Fog Seal Application
Within three (3) days of application of the chip seal, or as directed by the Engineer, the Contractor shall re-sweep
all excess aggregate from the roadway and adjacent areas and apply a fog seal of CRS-2P to the surfaces.
APPLICATION – SLURRY SEAL
Slurry Seal application rate shall be 18 lbs/sy minimum – 21 lbs/sy maximum.
The slurry shall be a homogeneous mixture, sufficiently stable during the entire mixing - spreading period so that
the emulsion does not break, there is no segregation of fines from the coarser aggregate, and the liquid portion of
the mix does not float to the surface. Total time of mixing, from introduction of emulsion to spreading shall be
two minutes or less.
Slurry mixtures placed in test strips shall conform to design mix with minor variations to obtain crack filling, bond
to pavement, and desired skid resistance texture. In the event the materials do not meet the requirements for
fluidity, non-segregation, or surface texture, a new job mix shall be formulated and tested. Work shall not proceed
before approval of a design mix and acceptance following the placing of a test strip.
General
The surface shall be fogged with water directly preceding the spreader if required by local conditions as directed
by the Engineer. No free water shall be on the surface of the pavement following fog spray. Rate of application of
the fog spray shall be adjusted during the day to suit pavement temperatures, surface texture, humidity, and
dryness of pavement surface. The slurry mixtures shall be of the desired consistency as it leaves the mixer, and no
additional elements shall be added. A sufficient amount of slurry shall be carried in all parts of the spreader at all
times so that complete coverage is obtained. No lumping, balling, or unmixed aggregates shall be permitted. No
segregation of the emulsion and aggregate fines from the coarse aggregate will be permitted. If the coarse
aggregate settles to the bottom of the mix, the slurry will be removed from the pavement. Breaking of the
emulsion in the spreader box will not be allowed. No streaks as caused by oversized aggregate will be left in the
finished pavement. Rippling of the finished pavement is undesirable and shall be minimized. The speed may be
reduced by the Engineer, if rippling of the surface occurs. At any time that segregation, texture, rippling or
application rate are in non compliance with the specifications due to mix equipment or workmanship, work will be
stopped until the Owner's representative is insured that the non conformance has been corrected.
REVISION OF SECTION 409
SEAL COAT
24
After lay-down work is completed and before final acceptance by the Engineer, spot application of slurry seal
material may be required to correct any deficiencies such as streaking, scuff marks, tire tracks, gaps, etc. to
improve the ride quality and overall appearance. Slurry seal material required to correct deficiencies due to
unsatisfactory workmanship will not be paid for but shall be at the Contractor's expense.
Joints
The longitudinal joint between adjacent lanes shall have no visible lap, pinholes, or uncovered areas. Build-up or
unsightly appearance shall be not be permitted on longitudinal or transverse joints. The use of burlap drags or
other type drags shall be at the direction of the Engineer. Thick spots caused by overlapping shall be smoothed
immediately with the hand squeegees before the emulsion breaks. Longitudinal joints shall be overlapped no
more than six (6) inches over previously placed slurry. Slurry seal will be measured and paid for by the square
yard of street surface properly sealed and accepted by the Engineer. Building paper shall be used at transverse
joints to minimize or eliminate overlap. When drags are used, they must be kept clean and free of build-up. Joints
shall be straight and have a neat appearance.
Hand Work
Approved hand squeegees with burlap drags shall be used to spread slurry in areas not accessible to the slurry
mixer. Care shall be exercised as to the specified application rate and workmanship, as to leave no unsightly
appearance from hand work..
Mix Stability
The mixture shall possess sufficient stability so that premature breaking of the material in the spreader box does
not occur. The mixture shall be homogeneous during and following mixing and spreading, it shall be free of
excess water or emulsion and free of segregation of the emulsion and aggregate fines from the coarser aggregate.
Spraying of additional water into the spreader box will not be permitted.
Lines
Care shall be taken to ensure straight lines along curbs, shoulders and joints. No runoff on these areas will be
permitted. Lines at intersections will be kept straight to provide a neat appearance.
Curing
Slurry treated areas shall be allowed to cure until such time as the Engineer permits their opening to traffic. The
slurry seal mixture shall be proportioned to permit traffic on the newly sealed surface within 1 to 4 hours of
placement. The Contractor shall protect the area with suitable barricades for the full curing period, per the
approved traffic control plan.
Rolling
Slurry seal placed on parking lots, alleys, cul-de-sacs or low traffic volume areas, as determined by the Engineer,
shall be rolled with a pneumatic tire roller with a minimum weight of four (4) tons. Rolling shall start when the
slurry seal has set sufficiently to prevent any pick-up of material and rolled a minimum of three (3) coverages by
the roller until a uniform surface is obtained. Payment for rolling will not be measured or paid for separately, but
shall be included in the unit price for Slurry Seal.
Cleanup
REVISION OF SECTION 409
SEAL COAT
25
All material swept or blown onto sidewalks, all trash, all discarded slurry seal material, or other refuse shall be
collected on a daily basis, removed from the site, and disposed of to a site approved by the Engineer.
Slurry seal on concrete curb, gutters, and crosspans will require removal by approved methods at the Contractors
expense.
All applied slurry surfaces shall be swept with a vacuum style sweeper to remove any excess raveled material
which becomes dislodged from the street surface after seven (7) working days. Dislodged material from the street
shall be disposed of to a site approved by the Engineer. Payment for sweeping shall be paid for separately as
described in Section 02000 "Revision of Section 105; Maintenance During Construction". Excessive raveling, as
determined by the Engineer, shall be swept by the Contractor at no additional cost to the Owner.

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

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.

Above: This photo illustrates reducing drop height, a required best
management practice.
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.

(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

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:

(vi) Manually remove mud, dirt, and debris from equipment and vehicle wheels, tires and
undercarriage.
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 Manualͳ
(b) Additional Best Management Practices: In the event 3.6(a)(i)-(ii) are ineffective to prevent off-
vehicle transport, the person, owner, or operator shall use at least one of the following best
management practices:

fugitive dust emissions and deposition of materials on roadways. Prevent water used for dust
control from entering any public right-of-way, storm drainage facility, or watercourse.
(ii) Other technology: use other equivalent technology that effectively eliminates off-vehicle
transport, such as limiting the load size to provide at least three inches of freeboard to prevent
spillage.
Above: This figure illustrates minimizing drop heights, a required best management practice for bulk
materials transport.
Dust Prevention and Control Manualͳͺ
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:

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.

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.
Dust Prevention and Control ManualʹͶ
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.*

(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.
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.

Dust Prevention and Control Manualʹ
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.
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.
Above: These photos illustrate alternative methods to mechanical blowing that can minimize dust
generation.

4.0 Dust Control Plan for Land Development Greater Than Five Acres
A dust control plan is required for all development projects or construction sites with greater than five
(5) acres in size. If the project is required to obtain a development construction permit, then the dust
control plan shall be submitted with the development review application or the development
construction permit application. A copy of the dust control plan shall be available onsite at all times for
compliance and inspection purposes.
For dust control plans associated with a Development Construction Permit (DCP) issued by the City,
applications for the DCP are available online at www.fcgov.com/developmentreview/applications.php.
The dust control plan may be submitted on the Dust Control Plan Form included in Chapter 4 of this
Manual or other equivalent format and shall include the following information:
x Project name and location.
x Name and contact information of property owner.
x Project start and completion dates.
x Name and contact information of the developer, general contractor, and each contractor or
operator that will be engaged in an earthmoving activity.
x Total size of the development project or construction site in acres.
x A description of the project phasing or sequencing of the project to minimize the amount of
disturbed surface area at any one time during the project.
x A list of each dust generating activity or source associated with the project.
x A list of each best management practice and engineering control that will be implemented for
each dust generating activity or source.
x A list of additional best management practices that will be implemented if initial controls are
ineffective.
x A signed statement from the property owner, developer, general contractor, and each
contractor or operator engaged in an earthmoving activity acknowledging receipt of the Dust
Control Plan and an understanding of and ability to comply with the best management practices
in the plan.

Description
Street, curb, and gutter activities include concrete and
asphalt installation, maintenance, repair, and
replacement; bridge maintenance; and painting and
striping. Procedures involving the maintenance of
streets, curbs, and gutters have the potential to impact
stormwater quality. Materials involved in these
activities should be used efficiently and disposed of
properly.
When services are contracted, this written procedure
should be provided to the contractor so they have the
proper operational procedures. In addition, the
contract should specify that the contractor is
responsible for abiding by all applicable municipal,
state, and federal codes, laws, and regulations.
Procedures
General
Protect storm drain inlets and drains with curb
socks, rock berms, inlet protection, or drain
covers/mats prior to any maintenance activity.
When saw cutting ensure that no slurry enters
the storm drain, let the slurry dry, sweep it up,
and properly dispose of the sweepings.
Do not perform concrete or asphalt patch work
during wet conditions whenever possible.
Leaking material containers should be properly
discarded and replaced.
Store materials in containers under cover when
not in use and away from any storm drain inlet.
Monitor equipment for leaks and use drip pans
as necessary.
Sweep or vacuum the roadway once
maintenance activities are complete.

Bridge Maintenance
Do not transfer or load any materials directly over waterways.
Secure lids and caps on all containers when on bridges.
Suspend drop cloths or nets below any bridgework where wastes, scraps, or drips
might be spilled into a waterway.
Concrete Maintenance
Minimize the drift of chemical cure on windy days by using the curing compound
sparingly and applying it close to the concrete surface.
Ensure there is a concrete truck washout area available or require the contractor to
wash out at the batch plant.
Whenever possible, recycle concrete rubble; otherwise, dispose of it as solid waste.
Asphalt Maintenance
Sweep to minimize sand and gravel from new asphalt from getting into storm
drains, streets, and creeks.
Do not allow asphaltic concrete grindings, pieces, or chunks used in embankments
or shoulder backing to enter any storm drain or watercourses. Apply temporary
perimeter controls. Install silt fence until the structure is stabilized or permanent
controls are in place.
Whenever possible, recycle broken asphalt. If impossible, dispose of as solid waste.
Drainage inlet structures shall be covered with inlet protection during application of
seal coat, tack coat, slurry seal, and/or fog seal.
Painting and Striping
If possible, schedule painting and striping projects during dry weather.
Use thermoplastic or epoxy markings in place of paint whenever feasible.
The pre-heater for thermoplastic striping and the melting tanks used during
pavement marking must be filled carefully to prevent splashing or spilling of
materials. Leave 6 inches at the top of pre-heater and the melting tanks to allow
room for material to move and splash when vehicles are deadheaded.

Spill Prevention and
Response
Description
Due to the type of work and the materials involved, many
activities that occur either at a municipal facility or as part
of municipal operations have the potential for accidental
spills. Some municipal facilities operate under Spill
Prevention Control and Countermeasures (SPCC) plans
that include procedures for spill response. Proper spill
response planning and preparation enables employees and
contractors to effectively respond to problems and
minimize the discharge of pollutants to the storm sewer
system.
When services are contracted, this written procedure
should be provided to the contractor so they have the
proper operational procedures. In addition, the contract
should specify that the contractor is responsible for
abiding by all applicable municipal, state, and federal
codes, laws, and regulations.
Procedures
Spill Prevention
Keep work areas neat and well organized.
Maintain a Material Safety Data Sheet (MSDS) for
each hazardous chemical. Follow the Outdoor
Material Storage procedures.
Provide tight fitting lids for all containers.
Keep containers clearly labeled. Labels should
provide name and type of substance, stock number,
expiration date, health hazards, handling
suggestions, and first aid information.
Store containers, drums, and bags away from direct
traffic routes to prevent accidental spills.
Inspect storage containers regularly for signs of
leaking or deterioration.
Replace or repair leaking storage containers.
Use care to avoid spills when transferring materials
from one container to another.

Use powered equipment or get assistance when moving materials to and from a
storage area. Use care to prevent puncturing containers with the equipment.
Do not wash down or hose down any outdoor work areas or trash/waste container
storage areas except where wash water is captured and discharged into the sanitary
sewer (if approved).
Conduct periodic inspections to ensure that materials and equipment are being
handled, disposed/recycled, and stored correctly.
Provide adequate spill kits or lockers with sufficient equipment and supplies
necessary for each work area where the potential for spills or leaks exists.
Inspect each spill kit or locker regularly and after each spill response. Replace any
spent supplies or repair any equipment that is worn or not suitable for service.
Stock adequate personal protective equipment.
Spill Response
Safety
Consider safety at all times. Anticipate and avoid all likely hazards. Never approach, contact, or
sample an unknown substance. If a highly toxic or flammable substance is discovered, staff
should leave the immediate area and contact the appropriate identified response authority, such
as the fire department. If there is any question about a substance, contact the appropriate
identified response authority or other designated representative.
Procedures
Stop the leading edge of the spill. Block or divert the spill to avoid discharge to the
storm sewer system and to minimize the area requiring cleanup.
Determine the source of the spill and stop the spill at its source by closing a valve,
plugging a leak, or setting a container upright. Transfer material from a damaged
container.
Identify the material and volume spilled. Contact the appropriate identified
response authority or other designated representative if you cannot identify the
material and its properties.
Refer to the MSDS to determine appropriate personal protective equipment, such as
gloves and safety glasses and appropriate cleanup methods.
Clean up spills immediately to prevent spreading of wastes by wind, rain, and
vehicle traffic and potential safety hazards.
Use sand absorbents or socks, pillows, or pads to quickly capture spilled liquid and
properly dispose of all clean-up materials. Use dry clean-up methods only.
Complete all necessary reports.
Page 3 of 4
Spill Reporting
A spill of any chemical, oil, petroleum product, or sewage that enters waters of the
state of Colorado (that include surface water, ground water, and dry gullies and
storm sewers leading to surface water) must be reported immediately to the
Colorado Department of Public Health and Environment.
Release of a substance into a storm drain, or onto a parking lot or roadway as part of
a storm sewer leading to surface water, is reportable. However, if the material can
be contained and cleaned within the storm sewer system to the degree that a
subsequent flow in the storm sewer will not flush the substance to waters of the
State, it may not need to be reported.
Contact the appropriate identified response authority within the municipality or
other designated representative and be prepared to provide details needed to report
the spill to the necessary agencies.
Detailed spill reporting guidance can be found at
http://www.cdphe.state.co.us/op/wqcc/Resources/Guidance/spillguidance.pdf
and http://www.cdphe.state.co.us/hm/spillsandreleases.htm

Utility and Storm Sewer
System Maintenance
Description
This procedure addresses utility and storm sewer system
maintenance. Utilities include power, sanitary sewer,
water conveyance systems, and the storm sewer system.
Power includes electrical and gas utilities. Maintenance
of power may require excavation and reinstallation of
lines including open cut trenching or directional boring
in landscaped areas or street right of way. Electrical and
gas line maintenance ensures services are provided to
businesses and households without interruption.
The sanitary sewer system is cleaned as part of routine
maintenance and on an emergency basis. Without
proper maintenance, sanitary sewer back-ups and
overflows may occur and can result in potential property
damage and significant health concerns if not properly
managed.
Water conveyance systems are flushed and pressure
tested as part of routine maintenance. Potable water
systems must be properly maintained to ensure delivery
of water that meets State and Federal health standards.
Failures result in water main breaks that can cause
property damage including erosion.
The storm sewer system is cleaned as part of routine
maintenance and on an emergency basis in the event of
flooding. Maintenance will remove pollutants and
ensure the system functions properly to avoid flooding.
Flooding, ponding, and uncontrolled sheet flow can
result in property damage and increased soil erosion.
When services are contracted, this written procedure
should be provided to the contractor so they have the
proper operational procedures. In addition, the contract
should specify that the contractor is responsible for
abiding by all applicable municipal, state, and federal
codes, laws, and regulations.

Stay alert for any signs of illicit discharges. This includes “dry weather” flows or
pipes or hoses emptying directly into waterways or the storm sewer system.
Report any suspicious discharges or dumping to your supervisor.
Electrical and Gas Utility Maintenance
To prevent sediment, mud and particles generated by power utility maintenance
from entering the stormwater system implement inlet protection, perimeter
control, street sweeping, vehicle tracking control, stockpile management and
material management BMPs.
Restore landscaped or hardscaped areas promptly.
Potable Water Line Flushing
Remove any debris from the gutter that could wash away with the water. If
possible, sweep the flow line before flushing the line.
Direct the water so that it is not flowing over exposed soil areas in order to minimize
erosion.
Water Line Breaks
Contain spoils by building berms or installing rock socks around the area of
disturbance.
Dewater the excavation by using a vac truck.
Discharge high chlorine water to the sanitary sewer via the nearest manhole, to a
water truck, through a dechlorinating diffuser, or other method of dechlorination.
Remove sediment from the street, curb, gutter and storm inlets as needed
immediately following the repair.
Where needed, install a temporary patch or repave as soon as practicable following
the repair.
If necessary, revegetate areas as soon as practicable following the repair.
Sanitary Sewer Backup
Clear line stoppage to prevent backup into house basements and manhole overflows.
Page 3 of 4
Contain overflows by using emergency generator, pump and/or a vac truck to
intercept flows. It may be necessary to construct additional containment.
Clean up spills by washing and vacuuming the affected areas. Lime may need to be
applied for disinfection of affected areas. Lime must be removed once disinfection is
complete.
Storm Sewer System Pipes, Catch Basins, Inlet and Outlet Structures, and Culverts
Clean storm sewer system by manual cleaning or jetting the pipes using a
jet/vacuum truck to remove the material.
Do not temporarily store collected storm system cleaning debris adjacent to any
surface water, storm drain inlet, or drainageway.
Storm sewer system maintenance wastes may be either non-hazardous or hazardous.
Solid non-hazardous waste may be disposed in a sanitary landfill or recycled.
Liquid non-hazardous waste must be evaporated before disposing of it into the
landfill or discharged to the sanitary sewer system with the approval of the local
wastewater treatment plant. Hazardous waste, as defined under Colorado
Hazardous Waste Regulations (6 CCR 1007-3), must be transported and disposed of
at a permitted disposal or treatment facility.
Replace or maintain “no dumping” stencils or plaques as necessary.
Remove trash from trash racks and grated openings.
Detention and Retention Ponds
Inspect the outlet works and remove trash or vegetation from the trash racks and
grates.
Inspect side slopes of the pond for erosion and reestablish vegetation as needed.
Remove and service fountains and aerator motors as recommended.
Report any suspected water quality problems such as a change in growth or
appearance of vegetation.
Report excessive sediment accumulation, standing water beyond the designed drain
down time or damage requiring additional maintenance.
Drainageways
Drainageways include drainage channels, ditches, grass swales, and washes.
Inspect drainageways for erosion and repair if necessary.
Remove and properly dispose of trash and debris from the drainageways. Remove
sediment which could impede flow in drainageways.
Leave an unmown buffer when mowing adjacent to drainageways to filter
pollutants. Do not leave grass clippings in or next to the drainageway. Do not apply
landscape chemicals in the buffer area.

Revision date:
10/19/2009 Page 2 of 3
1.0 Purpose
1.1 The purpose of this ESOP is to describe the appropriate methods of handling
power washing wastewater.
2.0 Scope
2.1 The scope of this ESOP is limited to the description of the allowable methods of
the disposal of power washing wastewater and the protection of the storm drainage
system; the scope does not include specifics on how to power wash.
3.0 Process
3.1 Power washing wastewater must be prevented from running uncontrolled in the
City’s storm water system. The system includes streets, inlets, gutters, ponds,
creeks, ditches, and the Poudre River. During the power washing activity, ensure
the wastewater is controlled by the utilization of the natural slope of the land, or
barriers such as inlet covers. Use of barriers on an impermeable surface also
requires that the wastewater be vacuumed, collected, and disposed of properly.
3.2 General pollution prevention procedures:
A. Use dry methods for surface pre-cleaning, such as using absorbent on
small oil spots and sweeping up trash, debris, dirt, and used absorbent
before power washing.
B. Minimize the amount of water used during power washing activities.
C. Avoid using cleaning products that contain hazardous substances (e.g.,
hydrofluoric acid, muriatic acid, sodium hydroxide, bleach) that can turn
wastewater into hazardous waste.
3.3 Prior to power washing, decide on one of the following methods of disposal:
D. Landscape--power washing wastewater may be discharged to
landscaped areas if the materials used and the material removed are
not harmful to vegetation, there is no ponding, and there is no
uncontrolled runoff to the stormwater system.
E. Wastewater treatment system-- As long as the collected wastewater
does not have an oil sheen, has a pH between 5 and 11, and does not
contain any hazardous or toxic substances, the wastewater may be
disposed of into the City’s wastewater treatment system.
1. If you add anything to the wash water (ie—a cleaning agent) or if you
have questions about the content of your power washing wastewater,

please contact the industrial pretreatment office at 221-6938.
2. Disposal into the City’s wastewater treatment system may be done
either by discharging directly to an inside drain, or by pump truck at
the Drake wastewater treatment facility. Disposing by pump truck
requires a waste hauler’s permit, and a 5 cent/gallon fee will be
charged. For fee information, or to obtain a permit, contact
the industrial pretreatment office at 221-6938.
F. Truck the waste to a different waste disposal facility.
3.4 Once wastewater has been collected, visible solids remaining in the collection area
must be swept up to prevent future discharges to the storm drain.
3.5 A sewer manhole cover may not be removed for disposal to the wastewater
system.
3.6 If you are working in an area that is serviced by a neighboring wastewater district,
such as South Fort Collins Sanitation or Boxelder, it is necessary to contact that
district’s industrial pretreatment coordinator before discharging to their system.
4.0 Training Requirements
4.1 The training requirement associated with this procedure is knowledge of the proper
management of power washing wastewater.

Outdoor Fleet Maintenance
Description
Although it is recommended that fleet maintenance
activities be conducted indoors or under cover, it is
sometimes necessary to perform fleet maintenance
outdoors (e.g., equipment is too large to fit inside the
maintenance building, temporary repairs need to be made
before the equipment can be moved to the maintenance
building, breakdowns, service calls).
Some potential pollutants typically associated with outdoor
fleet maintenance activities include oil, antifreeze, brake
fluid and cleaner, solvents, batteries, and fuels. Consult the
Spill Prevention and Response procedure and the Vehicle
Fueling procedure for additional information on those
topics.
When services are contracted, this written procedure
should be provided to the contractor so they have the
proper operational procedures. In addition, the contract
should specify that the contractor is responsible for abiding
by all applicable municipal, state, and federal codes, laws,
and regulations.
Procedures
Fleet Maintenance
Fleet maintenance should be performed inside
whenever possible.
If indoor maintenance is not possible, ensure
maintenance is performed in a location where
contact with stormwater is minimized, through
berming and appropriate routing of drainage.
Provide inlet protection (berms, weighted inlet
covers, etc.) for all adjacent inlets when work is
occurring in close proximity to a storm drain
inlet.
Have absorbent pads and drip pans accessible to
capture leaks and spills during maintenance
activities.
Keep equipment clean and do not allow
excessive build-up of oil and grease.

Perform regular preventative maintenance to
minimize the occurrence of leaks and major
repairs.
Recycle and/or dispose of all wastes
properly and promptly.
Do not dump any liquids or other materials outside, especially near or in storm
drains or ditches. Sweep and pick up trash and debris as needed.
Clean up spills promptly using dry methods (do not hose down). Consult the Spill
Prevention and Response procedure for more information. Cleanup is completed
only after absorbent and rags are disposed of properly.
Body Repair and Painting
Whenever possible, conduct all body repair and painting work indoors.
Use dry cleanup methods such as vacuuming or sweeping to clean up all metal
filings, dust, and paint chips from grinding, shaving, and sanding. Dispose of the
waste properly. Debris from wet sanding can be allowed to dry overnight, then swept
and vacuumed. Liquid from wet sanding should not be allowed to enter the storm
drain. Never discharge these wastes to the storm or sanitary sewer systems.
Minimize waste from paints and thinners by carefully calculating paint needs based
on surface area and using the proper sprayer cup size.
Clean spray guns in a self-contained cleaner. Do not dispose of cleaner waste in the
storm drain.
Use sanding tools equipped with vacuum capability (if available) to pick up debris
and dust.
Material Management
Store maintenance materials and waste containers (e.g., used oil and antifreeze) in
labeled containers under cover or in secondary containment (e.g., double-walled
tanks). Chemicals should not be combined in containers.
All hazardous wastes must be labeled and stored according to hazardous waste
regulations.
Carefully transfer fluids from collection devices to designated storage areas as soon
as possible. Do not store the transferred fluids adjacent to the containers.
Store new batteries securely to avoid breakage and acid spills.
Store used batteries indoors or in secondary containment to contain potential leaks.
Recycle used batteries.
Conduct periodic inspections of storage areas to detect possible leaks.
Page 3 of 4
Do not wash or hose down the storage area except in areas where the wash water will
only enter the sanitary sewer drain as an approved discharge. Use dry clean-up
methods as often as possible.
Keep lids on waste barrels and containers, and store them indoors or under cover to
reduce exposure to rain.
Periodically inspect and maintain all pretreatment equipment, including sumps,
separators, and grease traps to ensure proper functioning.
Parts Cleaning
Use designated areas for engine, parts, or radiator cleaning. Do not wash or rinse parts
outdoors. If parts cleaning equipment is not available, use drip pans or other
containment to capture parts cleaning fluids.
Use steam cleaning or pressure washing of parts whenever possible instead of solvent
cleaning.
When steam cleaning or pressure washing is used, only discharge wastewater to an
oil/water separator connected to the sanitary sewer.
When using solvents, rinse and drain parts over the designated solvent tank so that
fluids will not drip or spill onto the floor. Use drip boards or pans to catch excess
solutions and divert them back to the tank. Allow parts to dry over the hot tank.
Recycle cleaning solution when it becomes too dirty to use. Never discharge cleaning
waste to the storm or sanitary sewer systems.
Vehicle and Equipment Washing
Vehicles should be washed, whenever possible, in the municipality’s vehicle and
equipment wash area/bay or taken to a commercial car wash.
Employee Training
Train applicable employees on this written procedure. Information regarding how to avoid
and report spills will be presented during the training.
Periodically conduct refresher training on the SOP for applicable employees who
perform outdoor vehicle maintenance.
Records
The following records could be used to document activities performed:
Record of any major spills and the action taken.
Records of employee training with sign-in sheet.
Heavy equipment and vehicle maintenance logs.

Heavy Equipment and Vehicle
Maintenance
Description
Regular maintenance of municipal vehicles and equipment, or
municipality-contracted vehicles and equipment prolongs the life
of the municipality’s assets and prevents the leaking of hazardous
fluids commonly associated with normal wear and tear of vehicles
and equipment.
Potential pollutants generated at vehicle maintenance facilities
include oil, antifreeze, brake fluid and cleaner, solvents, batteries
and fuels.
When services are contracted, this written procedure should be
provided to the contractor so they have the proper operational
procedures. In addition, the contract should specify that the
contractor is responsible for abiding by all applicable municipal,
state, and federal codes, laws, and regulations.
Procedures
Maintenance activities should be performed inside a maintenance
building unless the equipment is too large to fit inside or
temporary repairs need to be made before the equipment can be
moved to the maintenance building. Consult the Outdoor Fleet
Maintenance procedure when it is necessary to perform repairs
outside of the facility (breakdowns, service calls, etc.).
Vehicle Storage
Monitor vehicles and equipment closely for leaks and
use drip pans as needed until repairs can be
performed.
When drip pans are used, check frequently to avoid
overtopping and properly dispose of fluids.
Drain fluids from leaking or wrecked vehicles and
from motor parts as soon as possible. Dispose of fluids
properly.
