SUPPLEMENTAL INFORMATION
REQUIRED FOR RENEWALOF
INDIVIDUAL NPDES STORM WATER
PERMIT

SUPPLEMENTAL INFORMATION REQUIRED FOR RENEWAL OF INDIVIDUAL
NPDES STORMWATER PERMIT
Two copies of each of the following shall accompany this submittal in order for the application
to be considered complete:
(Do not submit the site Stormwater Pollution Prevention Plan)
Initials
I. A current Site Map from the Stormwater Pollution Prevention Plan. The location of
industrial activities (including storage of materials, disposal areas, process areas and
loading and unloading areas), drainage structures, drainage areas for each outfall,
building locations and impervious surfaces should be clearly noted.
2. A summary of Analytical Monitoring results during the term of the existing permit
(if your permit required analytical sampling). Do not submit individual lab reports.
The summary can consist of a table including such items as outfall number,
parameters sampled, lab results, date sampled, and storm event data.
11 3. A summary of the Visual Monitoring results. Do not submit individual monitoring
(/ reports. The summary can consist of a table including such items as outfall number,
parameters surveyed, observations, and date monitoring conducted.
4. A summary of the Best Management Practices utilized at the permitted facility.
U Summary should consist of a short narrative description of each BMP's in place at
the facility. If the implementation of any BMP's is planned, please include
information on these BMP's.
9 5. A short narrative describing any significant changes in industrial activities at the
permitted facility. Significant changes could include the addition or deletion of
work processes, changes in material handling practices, changes in material storage
practices, and/or changes in the raw materials used by the facility.
6. Certification of the development and implementation of a Stormwater Pollution
9-11
Prevention Plan for the permitted facility (Sign and return attached form).
If the final year analytical monitoring of the existing permit term has not been completed
prior to filing the renewal submittal, then the last years monitoring results should be submitted
within 30 days of receipt of the laboratory reports. (i.e. do not withhold renewal submittal
waiting on lab results)

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

Summary of Storm Water Best Management Practices
Implemented at
UFP Salisbury, LLC
Salisbury, NC
In order to prevent contamination of storm water at the plant, the following best management practices
(BMPs) will be implemented:
Good housekeeping procedures will be utilized by the facility personnel to reduce the potential for
accidental spills and safety hazards. Housekeeping procedures will include prompt cleanup of all spills
and orderly material storage. Housekeeping practices will 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 will be communicated and emphasized to each
employee and contractor working in the facility. Housekeeping practices will be 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 will be 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 will be
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.
Page 1 of 2

• 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 northeast corner of the property where
storm water is conveyed into a dry, detention basin. This basin is covered by a well -established,
thick vegetative cover. The majority of storm water discharged into this basin infiltrates into the
ground. Discharges from this basin only occur during significant rainfall events.
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 have come
into contact with 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 of these materials are used and stored under cover.
• All of liquid petroleum ASTs are located under roofs and only properly trained staff are authorized
to conduct vehicle fueling activities.
