Toxic Pollutants


Who is Impacted?

Toxic emissions from asphalt plants fall within a two-mile radius of the facility.  There are 7,000 residents, six schools with 2,500 students, and 10,000 monthly trail users who work, live and play within a two-mile radius of the site.  Lincoln Middle School is a mere 1/2 mile away.  You can see the stacks from their soccer fields.  The new Science and Discovery Museum, much of Old Town and City Park are all within two miles and all are directly impacted by these hazardous pollutants.  The Poudre River, one of the last wild and scenic rivers in the country, and a major water source for Fort Collins, lies only feet from the plant.


Welcome to Citizens Against Asphalt Toxins (CAAT).  We are glad you are here! CAAT is a coalition of neighbors, HOAs, NPOs and businesses seeking the permanent relocation of Martin Marietta's Taft Hill Hot Mix Asphalt Facility.


Citizens Against Asphalt Toxins (CAAT) is seeking the permanent relocation of Martin Marietta's Taft Hill Hot Mix Asphalt Facility.  With the site's temporary permit about to expire, Martin Marietta is seeking a stationary permit to produce 

600,000 tons of asphalt per year on a site that is less than a half mile from schools and homes.

Getting involved and staying informed is most important.  You can do this right here.  It is important that the City of Fort Collins, Larimer County and the Colorado Department of Public Health and Environment hear your voice.

Fort Collins is one of the best places to live in the country.  Don't let heavy industry pollute the air we breathe and the water we drink. Our quality of life, our property values and our health and well-being are at risk.
