RE: Environmental Recycling and Disposal
Weld County
Dear Mr. Lang:
The Hazardous Materials and Waste Management Division (the
Division) of the Colorado Department of Health approval of the
Environmental Recycling and Disposal Facility was predicated on the
fact that the Tri-County Airport accepted only piston-type
aircraft. Under this scenario, the landfill would be located at a
distance greater than 5,000 feet from the end of the Tri-County
Airport runway and as such, did not require any special provisions
under the existing Solid Waste Regulations. However, it has
recently come to the Divisions attention that the Tri-County
Airport has been accepting non-commercial jets (primarily for
corporate customers) approximately once a year since the airport
opened in 1981.
The problems that have arisen due to this new information are:
1. The landfill falls into a category of less than 10,000
feet from an airport runway that is used by a turbojet.
2 . The current regulation states that disposal sites and
facilities located less than 10, 000 feet from the end of
an airport runway used by a turbojet shall not pose a
bird hazard to aircraft. Subtitle D states that 'The
owners or operators . . . must demonstrate that the units
are designed and operated so that the municipal solid
waste landfill (MSWLF) unit does not pose a bird hazard
to aircraft. '
3 . In addition, Subtitle D states that 'Owners or operators
• within a five-mile radius of any airport runway. .
. must notify the affected airport and the Federal
Aviation Administration (FAA) . '

The Division requests that the disposal site and facility evaluate
bird hazards posed to the Tri-County Airport. A report documenting
aircraft flight paths, bird flight paths and populations associated
with the landfill activity shall be prepared and submitted to the
governing body having jurisdiction and to this Division for review
and approval. The Division also requests that the affected
airports within a five mile radius of the site and the FAA be
notified of the existence of the MSWLF units (both existing and
proposed) .
Due to the importance and significance of this issue, your
immediate attention is necessary. I may be contacted at this
office if you have any additional questions.
