Permit issued: [month day, year] 13500008-101 Permit expires: [month day, year] Page 5 of 148 3. Facility description The Polaris Industries Inc - Roseau (Facility) is located at 301 5th Ave SW in Roseau, MN, Roseau County, Minnesota. Polaris Industries, Inc. located in Roseau, Minnesota designs, engineers, and manufactures off-road vehicles, including all-terrain vehicles and snowmobiles for recreational and utility use. The main emissions sources at the facility are coating operations, engine testing operations, and miscellaneous combustion sources. The permit limits the emissions from the facility such that the facility is classified as a minor source under Federal New Source Review regulations. These limits include limits on CO and VOC emissions at 20 tons per month based on a 12-month rolling average, and limits on PM, PM10, PM2.5 and NOx at 15 tons per month based on 12-month rolling average. The facility operates panel filters to control PM, PM10, and PM2.5 emissions from the spray booths and a thermal oxidizer to control CO and VOC emissions from engine testing operations. This permit action incorporates a major amendment received on September 24, 2015 and a minor amendment received on June 6, 2013. The major amendment authorizes the construction of two R&D engine test cells and a second thermal oxidizer. The amendment also adds the requirements for 40 CFR pt. 63, subp. PPPPP the NESHAP for Engine Test Cells/Stands. At the time of permit issuance, the Permittee is not subject to subp. PPPPP because the facility is an existing affected source as defined by the regulations. However, the Permittee anticipates the potential to trigger reconstruction under 40 CFR pt. 63 through future modifications or additions of engine test cells. Upon reconstruction, the Permittee would become subject to 40 CFR pt. 63, subp. PPPPP. The minor amendment adds a paint booth and associated make-up air unit.
