increasing stability of material
o Once the initial land clearing/earth movement activities are
complete, a second round of watering can generate a thin
crust which stabilizes the disturbed surface areas provided
that it is not disturbed
o Security fencing can be used to prevent unwanted future
disturbances of sites where a surface crust has been created
(B) Chemical stabilization o Only effective in areas which are not subject to daily disturbances
o Vendors can supply information on product application and
required concentrations
(C) Wind fencing o Three to five foot barriers adjacent to roadways or urban areas
can be effective in reducing the amount of wind blown
material leaving a site
o Should be used in conjunction with other measures
(D) Cover haul vehicles o Entire surface area should be covered once vehicle is full
(E) Wheel washers o Should be placed where vehicles exit unpaved areas onto paved
areas
o System can be adjusted to spray entire vehicle, including stored
bulk material in haul vehicles
(Z)
Unpaved (F) Paving o Requires street sweeping/cleaning if subject to material
Roads accumulation
(G) Chemical Stabilization o Vendors can supply information as to application methods and
concentrations
o Not recommended for roads with high volumes or those used for
heavy equipment
(H) Watering o In sufficient quantities to keep surface moist
o 'Required application frequency will vary according to soil type,
weather conditions, and vehicular use
(Source No) Reasonably Available
Source Control Measures

Unpaved (I) Reduce speed limits

(Cont'd) (1) Reduce vehicle trips
(3)
Storage

-------------
(4)
Paved
Road
Track -out
(K) Wind sheltering
(L) Wet suppression
Comments
o 15 mile per hour maximum
o Access restriction or redirecting traffic to paved roads in order to
reduce vehicle trips by a minimum of 60 percent
------------------------------------------------------------------------------------
o Choices include silos or enclosures
o Enclosures should consist of three sided barriers equal to height of
material with no more than 50 percent porosity
o Application methods include: spray bars, hoses and water trucks
o Frequency of application will vary on site specific conditions
(M) Chemical suppression o Best for use on storage piles subject to infrequent disturbances
(N) Altering loadin/loadout o Confine loadin/loadout procedures to leeward (downwind) side
procedures of the material
o Most effective when used in conjunction with wind sheltering
(0) Coverings o Tarps, plastic, or other material can be used as temporary
coverings
o When used, these should be anchored to prevent wind from
removing coverings
-------------------------------------------------------------------------------------------------------------------
(P) Wheel washers o Should be placed where vehicles exit unpaved areas onto paved
areas
o System can be adjusted to spray entire vehicle, including stored
bulk material in haul vehicles
(Q) Sweep/clean roadways o Either sweeping or water flushing may be used
(R) Cover haul vehicles - o Entire surface area should be covered once vehicle is full
----------------------------------------------------------------------------------------------------------------------
(5)
Disturbed (S) Chemical stabilization o Vendors can supply information on methods for application and
Areas/ required concentrations
Inactive
Construction
Sites
(T) Watering o Would require frequent applications unless a crust
can be developed over the site
(U) Wind fencing o Three to five foot barriers adjacent to roadways or urban areas
can be effective in reducing the amount of wind blown
material leaving a site
o Should be used in conjunction with other measures
(V) Vegetation o Establish as quickly as possible when active operations have
establishment ceased
o Use of drought tolerant, native vegetation is encouraged

The developer of the referenced project has requested the release of bond #156404S
in the amount of $6,000.00 for dust control measures, as was agreed to with their
PM -10 Fugitive Dust Mitigation Plan. As all site improvements have been completed,
the security is no longer needed. Please release the associated bond.
