Amid ongoing considerations from members of the general public about contamination associated to nuclear weapon parts, an indication from the Boulder County authorities outdoors of the Rocky Flats National Wildlife Refuge warns guests of potential publicity to “radioactive materials,” in accordance to county officers.
The signal sits the place the Coalton Trail approaches Colo. 128 and was put in in late December, in accordance to an e mail from county spokesperson Gloria Handyside. The trailway is one in every of a number of that lead into the Rocky Flats refuge space.
“Visiting Rocky Flats National Wildlife Refuge May Expose You to Radioactive Materials,” the textual content reads, in accordance to a pattern signal picture. It provides: “Hikers, Bikers, and Equestrians are encouraged to make informed decisions before entering the refuge.”
Westminster can be planning to set up an identical signal, in accordance to Andy Le, a metropolis spokesperson. The signal was being made and can be put in “in the coming weeks,” he mentioned. The signal can be situated close to an Indiana Street bridge, in accordance to Westminster City Council data.
“The sign is for educational purposes and empowers trail users to make a decision for themselves,” he mentioned.
The Colorado Department of Public Health and Environment was not consulted about the language used within the signage, in accordance to an e mail from Branden Ingersoll, a spokesperson for CDPHE’s Hazardous Materials and Waste Management Division.
“While local governments have the authority to post signage on local property, we want to clarify that the wording does not match the scientific findings from CDPHE or the Environmental Protection Agency,” Ingersoll mentioned.
Former nuclear plant space
The land within the space was as soon as house to the Rocky Flats nuclear weapons plant, established within the early Nineteen Fifties, in accordance to a Colorado Department of Public Health and Environment doc. The plant, which produced nuclear weapon parts for nationwide protection, concerned using radioactive supplies comparable to plutonium and uranium in addition to “other hazardous materials associated with manufacturing,” in accordance to the doc. While in operation, the plant launched contaminants into the surroundings by “routine air emissions and accidents, such as fire and spills,” the doc says.
The plant’s manufacturing mission was terminated within the early Nineteen Nineties, and the state and the U.S. Environmental Protection Agency supervised an investigation and remediation of environmental contamination at the location, the doc says. Remediation of the Rocky Flats website was accomplished in 2005, and jurisdiction of many of the website was turned over to the U.S. Fish and Wildlife Service to be operated as a wildlife refuge shortly after, the doc says. The Fish and Wildlife Service couldn’t be reached Thursday for remark about the brand new signal.
Boulder County Parks and Open Space workers got route by county commissioners to set up the signal “in response to requests from members of the public for additional signage,” Handyside mentioned.
A gaggle referred to as Rocky Mountain Peace and Justice Center and a corporation referred to as Physicians for Social Responsibility Colorado co-led a marketing campaign for warning signage round Rocky Flats, in accordance to Chris Allred with the peace and justice middle group.

The wildlife refuge opened to the general public in 2018, however the signage put in by Fish and Wildlife is “inadequate and misleading about the full history and current risks of recreation at Rocky Flats,” Allred mentioned.
“While the refuge is now open to visitors year-round, radioactive and hazardous materials remain in the soil and ground water and may be present in airborne dust particles,” the offered pattern textual content of the signal says. “Nearby communities and industry professionals continue to express concern about the area’s safety and its risks to human health.”
(For Westminster, metropolis workers was set to make an adjustment to the signal, together with to add the phrase “some” earlier than “industry professionals,” in accordance to a City Council assembly doc.)
“After decades of advocacy from the state to the municipal and county levels, we finally will have strong warnings posted around Rocky Flats,” Allred mentioned in a information launch. “We appreciate these important steps by the Boulder County Commission and Westminster City Council to bring more transparency and public health (protection) to the region. It is time for other communities bordering Rocky Flats to follow suit.”
State public well being division on danger
CDPHE continues to take into account the refuge secure for public use below “federal health protection standards,” Ingersoll mentioned.
“CDPHE and EPA conducted years of investigation and risk assessment at Rocky Flats using … thousands of environmental samples,” he mentioned. “Based on that work, regulators determined that the Rocky Flats National Wildlife Refuge is suitable for unlimited use and unrestricted exposure, meaning no special public health precautions are required for the refuge acreage.”
A 2020 CDPHE evaluation of potential radiation publicity from close by building discovered projected doses properly beneath regulatory limits and more moderen air sampling related to path work measured a fraction of the federal public dose customary, in accordance to Ingersoll.
Trails inside the refuge don’t enter the previous industrial manufacturing space, which continues to be individually managed and controlled, in accordance to Ingersoll.
“We understand people may view risk differently. Our role is to share the scientific and regulatory findings that guide our decisions,” Ingersoll mentioned. “Based on decades of investigation and oversight, CDPHE and EPA continue to consider the refuge safe for public use under federal health protection standards.”
