<br />Bituminous Roadways, Inc. Hot Mix Asphalt Plant Project Conclusions of Law
<br />Columbus, Minnesota And Order

<br />C. This subpart applies to any industrial, commercial, or institutional project which includes
<br />multiple components, if there are mandatory categories specified in subparts 2 to 13, 16, 17,
<br />20, 21, 23, 25, or 29, or part 4410.4400, subparts 2 to 10, 12, 13, 15, or 17, for two or more of
<br />the components, regardless of whether the project in question meets or exceeds any threshold
<br />specified in those subparts. In those cases, the entire project must be compared to the
<br />thresholds specified in items A and B to determine the need for an EAW. If the project meets or
<br />exceeds the thresholds specified in any other subpart as well as that of item A or B, the RGU
<br />must be determined as provided in part 4410.0500, subpart 1.
<br />
<br />28. For legislative purposes, Minn. Stat. § 410.01 classifies cities into numerical classes based on the
<br />number of inhabitants. Based on the City of Columbus listed population of 3,387, the City of
<br />Columbus is a fourth class city. For population information, see the 2016 League of Minnesota Cities
<br />Directory of Minnesota City Officials.
<br />
<br />29. The Project’s gross floor space of the office/laboratory and vehicle maintenance building is less than
<br />5,000 square feet.
<br />
<br />30. The hot mix asphalt plant and the temporary crusher do not have “gross floor space” as that term is
<br />used in Minn. R. 4410.4300, sub. 14. However, if this Finding is incorrect, a gross floor space of
<br />150,000 square feet would have to be assigned to the hot mix asphalt plant and temporary crusher
<br />structures to meet the mandatory EAW threshold of 200,000 square feet for an industrial,
<br />commercial or institutional facility proposed to be located in a third or fourth class city. Based on
<br />the plans and specifications sheets supplied in Appendix A of the Petition (Attachment 1 to the
<br />Findings), the hot mix asphalt plant and temporary crusher structures do not approach 200,000
<br />square feet of combined gross floor space.
<br />
<br />31. There are no structures in the proposed Project other than the structure described in findings 30
<br />and 31. Therefore, based on the population of the City of Columbus and the Project’s proposed
<br />gross floor space, the Project does not meet the mandatory EAW threshold for an industrial,
<br />commercial or institutional facility under Minn. R. 4410.4300, subp. 14.
<br />
<br />Hazardous Waste Facilities
<br />
<br />32. Minn. R. 4410.4300, subp. 16 states:
<br />A. For construction or expansion of a hazardous waste disposal facility, the PCA shall be the RGU.
<br />B. For construction of a hazardous waste processing facility with a capacity of 1,000 or more
<br />kilograms per month, the PCA shall be the RGU.
<br />C. For expansion of a hazardous waste processing facility that increases its capacity by ten percent
<br />or more, the PCA shall be the RGU.
<br />D. For construction or expansion of a facility that sells hazardous waste storage services to
<br />generators other than the owner and operator of the facility or construction of a facility at
<br />which a generator's own hazardous wastes will be stored for a time period in excess of 90 days,
<br />if the facility is located in a water-related land use management district, or in an area
<br />characterized by soluble bedrock, the PCA shall be the RGU.
