In April 2015, Martin Marietta Materials (MMM) submitted an application for a Use by Special Review (USR) permit to Weld County asking to build a major aggregate processing facility on WCR 13, ½ mile south of its intersection with US 34. This facility would introduce heavy industrial activities to this agriculturally zoned land.
The planned facility would include:
- a continuous operation asphalt drum plant that would produce as much as 475,000 tons per year,
- a concrete batch plant that would be permitted at 400,000 cubic yards per year,
- a concrete crusher for concrete recycling,
- asphalt recycling,
- up to 1 million tons per year of additional aggregate distribution from this site, and
- all aggregate would be brought to the site by train and delivered onto a 7,000 foot long rail spur.
Over 150 trains per year would be required to deliver sufficient aggregate, most of which would be in the summer, resulting in a train every day for months. According to MMM, each train would require as much 8 hours to unload. All of this activity would support the aggregate industry in Wyoming.
An aggregate processing facility with these activities, at this magnitude, creates serious problems for nearby residents and small businesses. The facility is not compatible with surrounding land uses; will introduce safety hazards by adding large amounts of truck traffic to an already busy highway, creating a fire hazard, and generating small particulate pollution; will destroy quality of life for residential neighbors by generating high noise levels, hazardous dust, and unpleasant odors; will reduce nearby property values; and will destroy nearby small businesses, including an organic farm that grows herbs for pregnant women and a wedding venue.
For more than three years, CLR-34 NA has been fighting to prevent MMM from proceeding with the facility.
