FUGITIVE DUST CONTROL PROGRAM
Revision 6
Fugitive Dust Control Plan
FUGITIVE DUST CONTROL PROGRAM Rev 6.doc
Objective
The objective of this document is to outline the plans and procedures in place to
minimize fugitive dust at the Weyerhaeuser Company Oriented Strand Board facility
located in Crawford County, Michigan. The plan describes fugitive dust control activities
and procedures in four areas; storage piles, material handling systems, unpaved
roadways and yard areas, and paved roadways and yard areas.
Applicability
The Weyerhaeuser facility is operated under Renewable Operating Permit No. MI-ROPB7302-2010a, amended January 29, 2013 by the Michigan Department of Natural
Resources and Environment - Air Quality Division. That permit requires that "Applicant
shall implement and maintain the program for continuous fugitive emission control for all
plant roadways, the plant yard, all material storage piles, and all material handling
operations as approved by the District Supervisor." This plan has been drafted in
accordance with the rules provided in MACR336.1371 - 1373 to comply with this
requirement.
Fugitive Dust Control Program
Storage Piles
The primary storage area for hogged bark, wood and fines is the Hogged Fuel
Building located at the south side of the mill complex. The purpose of this
building is to protect these materials from the elements and reduce their
introduction into the air from the wind. Loading of trucks with hogged fuel also
occurs within the confines of this building to reduce the generation of fugitive
dust.
Routine storage of wood fiber, bark and other related materials in outdoor
storage piles will be limited to areas used for wood residuals recovery and
processing operations and seasonal piles accumulated for the purpose of
managing snow melt and clean-up. All other outdoor storage piles will be
minimized to the greatest possible extent.
Small storage piles that may arise or accumulate outdoors as a result of clean-up
activities or other temporary storage needs will be removed to either the Hogged
Fuel Building or the routine storage areas described above within 72 hours time.
Handling of such materials will be done by front-end loader at appropriate speeds
and bucket position to minimize spillage. Any spillage that does occur from
material handling with mobile equipment will be cleaned up within 72 hours time
and removed to the Hogged Fuel Storage Building.
Material Handling Systems
All belt conveyors used at the facility for conveying materials in outdoor areas will
be covered. Belt transfer points will also be enclosed with chutes or hoods,
wherever practical, to minimize fugitive dust emissions. Any materials that may

accumulate below a conveyor or at a transition point will be cleaned up and
removed to the Hogged Fuel Building within 72 hours time.
Pneumatic systems used to convey dry fines material are not addressed in this
plan. All ductwork, blowers, cyclones and bag filters associated with the
pneumatic systems used at the facility are aggressively operated and maintained
in accordance with the facility's Malfunction Abatement Plan. Under this plan,
any visible emissions from pneumatic systems are considered malfunctions and
are addressed immediately.
Unpaved Roadways and Yard Areas
The primary unpaved roadway of concern in this plan is the road along the far
west side of the wood yard. Traffic from this road that was used by trucks
transporting hogged fuel to an off-site location has been diverted to a newly
paved area of the yard. The trucks themselves are not typically sources of
fugitive dust due to the particle size and moisture content of the materials they
are transporting. Potential fugitive dust in this area would be generated from the
unpaved roads that the trucks travel on.
This road will continue to be maintained as needed to keep the surface free from
pot holes and wash-boarding. The road surface will also be treated with dust
suppressants, as needed but will no longer be treated with dust suppressant
applications on a regularly scheduled basis. Vehicles traveling these roads will
also be limited to whatever speed is appropriate to minimize dust generation.
Unpaved yard areas prone to fugitive dust generation due to the travel of mobile
equipment will receive dust suppressant applications as needed. Those unpaved
areas receiving routine mobile equipment traffic will be considered for further site
development, in terms of paving or other suitable hard surface, subject to capital
availability. Other unpaved areas will be provided a vegetative cover where
practical.
Paved Roadways and Yard Areas
All paved areas will be cleaned periodically to control wind blown dust from these
surfaces. Cleaning will involve the use of a combination of methods including
water washing, sweeping and the use of other hand and power tools. Pavement
cleaning will be conducted as frequently as weather permits during the snow free
season. At a minimum, all paved surfaces will be cleaned once every calendar
month. Dust suppressants may be applied to these surfaces as well as an
alternative control measure.
Record Keeping
The facility will maintain vendor invoices to document the date and time of dust control
applications made to unpaved surfaces. These documents will be maintained for a
minimum of five years and will be made available to the MDEQ upon request.
