The requirements from `Section 503.2 Fans and Section 510.7 both pertain to fans conveying explosive or flammable vapors,fumes or dusts. In the attached documents,Robert weed is providing clarification that the duct collection system contains very low concentrations of duct particulate. This can be directly attributed to the infrequent use of equipment combined with low amounts of material generation. There are three attachments with supporting information: 1. A signed letter from Matt Bunner,VP of Operations at Robert Weed,clarifying how the equipment will be utilized and the approximate hours per week of operation. It is supplemented with a Cad layout including equipment identifiers. 2. An additional letter from Matt Bunner, showcasing his current operations in Bristol, Indiana and the correlating dust suppression systems installed. The intent is to show that the equipment and operations being proposed in Twin Falls is not unique and that there are years of operational experience with similar installations. 3. A letter from Carl Schalm who is a senior loss control representative from Pennsylvania Lumbermens Mutual Insurance Company. His company insures Robert Weed's operations. After reviewing the proposed project in Twin Falls, his company's opinion is that the installation would not require a fire suppression system due to the low hazards involved. Thank you for taking the time to review this installation for the project. Please feel free to contact me directly if have any questions or concerns.

Per your request for details of how and when the equipment will be used. (see A,B,C references on attached CAD layout#1 Twin Falls plant): A).The dust collector is connected for pickup to two profile wrappers and one panel laminator and one cold press glue applicator. All of these machines need dust collection to vacuum away the small amount of nuisance dust on a sheet of plywood that could cause a surface imperfection under the decorative vinyl laminate. These machines possibly run up to 40 hours per week. B).Additionally,the collector is connected to one gang rip saw that runs approximately one day or less per week. The one or two saw blades used in a typical job setup do not produce more than a few pounds of dust per hour. The collector is also connected to a vertical panel saw that runs one day or less per week. This saw has one blade,and produces even less dust output than the gang rip saw. C).The last machine connected to the dust collector is a double end tenoner. This machine trims the end of a fabricated hollow core door for the RV industry. The end trim is accomplished by a shaper and saw blade combination. Having never yet run this equipment, I cannot estimate the sawdust output, but currently we have a goal of 500 doors production per week for 2013. The trim of oversized material is by design less than 1/8"on four sides,so I anticipate small dust output here also. Please let me know if further information is needed.

Per your request for details of similar facilities, see attached Bristol Indiana plant layout encompassing 750,000 sf of production and warehouse areas. Most areas at Robert Weed Plywood serviced by dust collection equipment do not have spark suppression, because Pennsylvania Lumbermens Mutual Insurance has verified our production processes do not produce sparks and risk of fire. A. We do have spark suppression in WPD area building#5. This department has many saws,CNC routers, edgebanders,foilers,etc. The dust volume produced is substantial. B. Spark suppression is also in place in the collector line to the silo. This is a pickup from two departments,and it was judged a valid use of spark suppression because so many machines feed into this collection point. C. Milling area with 7 moulders and 3 saws does not have spark suppression. It was judged not necessary due to only wood cutting and the slight risk of a woodworking tool creating a spark. D. WPD buildings #31 and #32 do not have spark suppression,due to only wood cutting and the slight risk of a woodworking tool creating a spark. E. LPD panel lamination area does not have spark suppression, as only nuisance dust on a plywood panel is brushed and vacuumed off the surface to prevent a visual blemish in the finished panel product. Please let me know if further information is needed. Thank you, Matt Bunner V.P. Operations Robert Weed Plywood Corporation .r ! ! F . I i+ 1 1 u •� M 7 �- I 2 L '� i 1 c to y t•1!

Dear Matt, PLM(Pennsylvania Lumbermens Mutual Insurance Company)is the largest insurer of the wood industry.With over one hundred years insuring the niche we have extensive experience in all hazards associated with wood processing.After discussion with the manufacturers of the SDFS equipment and the other insurers in the wood manufacturing area,we have developed a list that we use to decide if STFS is required. 1. There must be 5 or more machines being run on the system. Machines must be of 15 hp or more and must be running at the same time. 2. The wood being machines must be dried wood not green. 3. There must be at least 20 feet of duct to install the STFS system. 4. If the wood is Walnut the above does not apply and a STFS system must be installed. The insurance industry has developed these requirements because we do not feel that systems with less equipment or operations that use machines infrequently, generate enough refuse to cause an explosion hazard per NFPA 664.1 have been told that RWP will be operating one rip saw and a shaper at the Idaho location.In addition the machines will not be operating each day of the week.With this information,as the representative for PLM and also according to court cases "The Authority Having Jurisdiction", I will not require the installation of a STFS system in the plant.
