SUMMARY of STORM WATER BEST
MANAGEMENT PRACTICES (BMPS)
IMPLEMENTED AT FACILITY

Summary of Storm Water Best Management Practices
Implemented at
UFP Rockwell, LLC
Rockwell, NC
In order to prevent contamination of storm water at the plant, the following best management practices
(BMPs) are being utilized:
Good housekeeping procedures are utilized by the facility personnel to reduce the potential for
accidental spills and safety hazards. Housekeeping procedures include prompt cleanup of all spills and
orderly material storage. Housekeeping practices also include ensuring sufficient aisle space is available
for the movement of spill or emergency response equipment through the facility, as needed.
The need and reasons for good housekeeping and BMPs is communicated and emphasized to each
employee and contractor working in the facility. Housekeeping practices are part of each person's job,
with emphasis on preventing contamination, as opposed to remediating contamination after it has
occurred. Each supervisor is responsible for assuring that housekeeping is completed as part of each
person's job.
The following lists provide various structural and non-structural BMPs specifically developed for wood
industry facilities as identified through various industry and regulatory sources. These BMPs are being
implemented, as applicable. The BMPs will be inspected and evaluated on an annual basis, and a record
of such activities will be maintained. These BMPs identify methods and practices employed by the
facility to minimize the contact of its products and equipment to storm water.
1. Housekeeping Practice BMPs
General Policy.
o Floors are to be kept dry and free of waste material.
o Garbage and other waste material will be regularly collected and disposed of inappropriate
dumpsters. (OMP - Policy #7004, General Work Place Safety Rules)
o Sawdust accumulation that does occur will happen only in areas not exposed to storm
water.
o Every employee is responsible for good housekeeping and management will conduct
inspections.
Trash Pickup.
o Trash and debris will be picked up as often as necessary to maintain the area. Exterior
dumpsters should remain covered and filled only to capacity.
• Loading and Unloading.
o These areas of the Storage Yard will be inspected regularly and kept free of clutter and
trash.
• Fuel Storage.
o Only authorized staff properly trained in spill prevention and response is authorized to
conduct fueling operations. Small releases during fueling operations (i.e., drips) will be
cleaned up immediately.
Page 1 of 2

• Product Storage.
o Areas will be kept free of clutter and trash. Storage areas will be located on stable, well
drained areas.
• Equipment Maintenance.
o Areas are inspected regularly and kept clear of debris and discarded items. Vehicle
maintenance should be conducted in covered, paved areas to prevent exposure to storm
water.
2. Preventative Maintenance & Visual Inspections BMPs
General Policy.
o The parking lot and plant yard are to be cleaned of any debris daily.
o Gutters, swales, ditches, and downspouts will be checked to ensure proper drainage as
needed.
o Fueling of vehicles will be done only by authorized staff properly trained in spill prevention
and response.
o Minor spills of fuel or oil around the yard will be absorbed with appropriate materials and
disposed of in an appropriate manner.
o Inventory control of the lumber products will be performed. During inventory, the storage
yard will be visually inspected to ensure that pollution prevention practices are being
implemented in the raw material and finished products' storage areas. (APM - Policy
#2501, Inventory Count Policy)
o Forklifts will be checked daily for leaks of petroleum or hydraulic fluid (OMP - Policy #7320,
Forklift Operator Safety and Qualifications).
o As a general rule, all plants are discouraged from using herbicides for weed control. If plant
management opts to use an herbicide for vegetation control, only non -restricted herbicide
will be used and all manufacturer's label directions be followed. (OPM — Policy #7105,
Hazard Communication/Right to Know).
3. Runoff Management BMPs
• Grading immediately around the buildings diverts surface storm water away from buildings and
material storage areas. The facility slopes downward to the southeast corner of the property where
storm water is conveyed into a roadside storm water ditch.
4. Manufacturing Operations BMPs
• UFP's wood preserving operation is located within a building. The preservative is applied
within a closed cycle system that recycles water and reuses the process suspension; so no waste
or effluent is created or discharged. There is no discharge of process waters that contact the
treatment chemicals or the treated wood product. All process waters are recycled back into
the system via a collection sump. The treatment plant has been designed to contain the
volume of all tanks inside the plant in the event of simultaneous failure.
• New and used motor oil, hydraulic oil, lubricants, and cleaning products are stored in containers
ranging in size from one -gallon jugs, five -gallon pails, to 55-gallon drums. Used oil is stored in a 55-
galon drum within secondary containment. All these materials are used and stored under cover.
• The liquid petroleum AST has integral secondary containment and only properly trained staff are
authorized to conduct vehicle fueling activities.

The need and reasons for good housekeeping and BMPs is communicated and emphasized to each
employee and contractor working in the facility. Housekeeping practices are part of each person's job,
with emphasis on preventing contamination, as opposed to remediating contamination after it has
occurred. Each supervisor is responsible for assuring that housekeeping is completed as part of each
person's job.
The following lists provide various structural and non-structural BMPs specifically developed for wood
industry facilities as identified through various industry and regulatory sources. These BMPs are being
implemented, as applicable. The BMPs will be inspected and evaluated on an annual basis, and a record
of such activities will be maintained. These BMPs identify methods and practices employed by the
facility to minimize the contact of its products and equipment to storm water.
1. Housekeeping Practice BMPs
• General Policy.
o Floors are to be kept dry and free of waste material.
o Garbage and other waste material will be regularly collected and disposed of in appropriate
dumpsters. (OMP - Policy #7004, General Work Place Safety Rules)
o Sawdust accumulation that does occur will happen only in areas not exposed to storm
water.
o Every employee is responsible for good housekeeping and management will conduct
inspections.
Trash Pickup.
o Trash and debris will be picked up as often as necessary to maintain the area. Exterior
dumpsters should remain covered and filled only to capacity.
• Loading and Unloading.
o These areas of the Storage Yard will be inspected regularly and kept free of clutter and
trash.
• Fuel Storage.
o Only authorized staff properly trained in spill prevention and response is authorized to
conduct fueling operations. Small releases during fueling operations (i.e., drips) will be
cleaned up immediately.

Product Storage.
o Areas will be kept free of clutter and trash. Storage areas will be located on stable, well
drained areas.
• Equipment Maintenance.
o Areas are inspected regularly and kept clear of debris and discarded items. Vehicle
maintenance should be conducted in covered, paved areas to prevent exposure to storm
water.
2. Preventative Maintenance & Visual Inspections BMPs
General Policy.
o The parking lot and plant yard are to be cleaned of any debris daily.
o Gutters, swales, ditches, and downspouts will be checked to ensure proper drainage as
needed.
o Fueling of vehicles will be done only by authorized staff properly trained in spill prevention
and response.
o Minor spills of fuel or oil around the yard will be absorbed with appropriate materials and
disposed of in an appropriate manner.
o Inventory control of the lumber products will be performed. During inventory, the storage
yard will be visually inspected to ensure that pollution prevention practices are being
implemented in the raw material and finished products' storage areas. (APM - Policy
#2501, Inventory Count Policy)
o Forklifts will be checked daily for leaks of petroleum or hydraulic fluid (OMP - Policy #7320,
Forklift Operator Safety and Qualifications).
o As a general rule, all plants are discouraged from using herbicides for weed control. If plant
management opts to use an herbicide for vegetation control, only non -restricted herbicide
will be used and all manufacturer's label directions be followed. (OPM — Policy #7105,
Hazard Communication/Right to Know).
3. Runoff Management BMPs
• Grading immediately around the buildings diverts surface storm water away from buildings and
material storage areas. The facility slopes downward to the southeast corner of the property where
storm water is conveyed into a roadside storm water ditch.
4. Manufacturing Operations BMPs
• UFP's wood preserving operation is located within a building. The preservative is applied
within a closed cycle system that recycles water and reuses the process suspension; so no waste
or effluent is created or discharged. There is no discharge of process waters that contact the
treatment chemicals or the treated wood product. All process waters are recycled back into
the system via a collection sump. The treatment plant has been designed to contain the
volume of all tanks inside the plant in the event of simultaneous failure.
• New and used motor oil, hydraulic oil, lubricants, and cleaning products are stored in containers
ranging in size from one -gallon jugs, five -gallon pails, to 55-gallon drums. Used oil is stored in a 55-
galon drum within secondary containment. All these materials are used and stored under cover.
• The liquid petroleum AST has integral secondary containment and only properly trained staff are
authorized to conduct vehicle fueling activities.
