On the Need for an Environmental Assessment Worksheet Findings of Fact Bituminous Roadways, Inc. Hot Mix Asphalt Plant Project Conclusions of Law Columbus, Minnesota And Order 2 and toilet waste. Bituminous will install a private well for building use and for periodic spraying for fugitive emissions at the Project site. 5. Bituminous will pave the area in and around the asphalt equipment with asphalt and will also pave two access roads with asphalt. The Project site areas not paved with bituminous will be covered with gravel. Bituminous will create almost 21 acres of impervious surface from the 46-acre Project site. 6. Bituminous will construct nonpermeable secondary containment areas for the above ground storage tanks that are part of the hot mix asphalt plant. 7. According to plan information Bituminous provided to the City of Columbus, Bituminous will grade both Lot 1 and Lot 2 and install stormwater controls. Bituminous plans to install a permanent stormwater sedimentation pond on the east side of Lot 1, and a permanent stormwater sedimentation pond on the southeast area of Lot 2, which is adjacent to the northwest area of Lot 1. 8. Bituminous proposes to operate the hot mix asphalt plant during construction season, which is typically from April through November of each year. Bituminous expects to operate the Project from 7 a.m. to 7 p.m. Monday through Saturday, but may also have periodic overnight operation of the Project. Bituminous is subject to the City of Columbus’ ordinances and any additional restrictions the City of Columbus may impose related to Bituminous’ days and hours of operation. 9. Bituminous will also hire a contractor to bring a portable crusher onto the Project site twice per year during construction season, each time for a period of approximately three to four weeks, to crush rubble concrete and asphalt for use in the hot mix asphalt production. The contractor will then remove the portable crusher after each time period, so the portable crusher will not remain on the Project site. Petition for Environmental Assessment Worksheet 10.
