Part 150 Study Documents
By benchmarking and understanding how aircraft noise behaves helps us better understand how it may affect our neighboring communities. Centennial Airport takes noise seriously. In fact, we've invested more than $2 million over the past 20 years to make sure we are doing our part to be good neighbors.
Introduction to Part 150
Part 150 Study Understanding Noise Compatibility
The FAR Part 150 Study is a formal evaluation of aircraft noise and land use compatibility authorized under the U.S. Code of Federal Regulations (14CFR) Part 150, titled "Airport Noise Compatibility Planning." It is a voluntary Federal Aviation Administration (FAA) program in which Centennial Airport has participated in the past, completing an original study in 1998, with subsequent amendments. The current Part 150 Study and subsequent updates present aircraft noise based on current conditions and forecast aircraft activity in five years.
In 1997, a grant application was submitted to the Federal Aviation Administration (FAA). Barbara Dunkelberg & Company was selected in September of 1998 to conduct the study.
As a result of that study, two committees were formed, one representing the technical aspect of the study (Technical Advisory Committee, TAC) and the other representing the communities (Community Advisory Committee, CAC) around the airport. The consultant worked with the committees to develop and prioritize the following 12 recommendations:
- Ban Stage 1 aircraft
- Ban Stage 2 jet aircraft under 75,000 lbs. at night
- Implement-010 degree departure heading for business jets at night
- Test 24-hours of Flight Tracks between 350 and 010-degree headings
- Eliminate preferential runway use procedure
- Implement 170 degree departure to 4 DME or 8,000 MSL (+/- 20 degrees)
- Amend community plans and zoning ordinances
- Update and establish environmental/noise abatement liaison/office
- Install noise monitoring system and develop a program
- Development/implementation of the Fly Quiet Program
- Operations review and Part 150 Updates
- Establish follow-up roundtable / committee.
The consulting firm also developed existing, and future, noise exposure maps (NEMs) based on the recommendations and forecasts. These are the noise contour maps that define the National DNL 65 threshold noise standard as well as lower and higher noise contours.
On Oct. 11, a public hearing, proceeded by an open house, was held to provide all interested parties with an opportunity to voice their ideas/concerns. Then on Nov. 15, the Airport Authority Board approved the Committee's recommendations in order to formally submit the recommendations to the FAA. The next step is for the FAA to place the recommendations on the docket and acceptance of the NEM's begins the 180-day FAA review process. The FAA can then either approve, disapprove, or approves as a voluntary measure only, the recommended alternatives of the noise compatibility program. The final step in the formal Part 150 process is for the Airport to begin implementation of the airport noise mitigation program.

NEM Federal Register Announcement
Noise Exposure Map Determination
Centennial Airport, Englewood, CO
This serves to provide public notice that, on Aug. 7, 2017, the Federal Aviation Administration (FAA) announced its determination that the 2016 Existing Condition Noise Exposure Map and 2021 Future Condition Noise Exposure Map submitted by the Arapahoe County Public Airport Authority for Centennial Airport under the provisions of 49 USC 47503 and 14 CFR Part 150 were found to be in compliance with applicable requirements.
The Noise Exposure Maps and supporting documentation are available for public inspection during normal business hours 8 a.m. to 5 p.m., Monday through Friday at 7800 S. Peoria St., Englewood, CO 80112. Maps and supporting documentation can be viewed online, as discussed below.
As indicated in 49 USC 47506, as of the date of this notice, no person who acquires property or an interest in a property in an area surrounding the airport, having actual or constructive knowledge of the existence of the Noise Exposure Maps, will be entitled to recover damages with respect to the noise attributable to the airport unless such person can show that (1) after acquiring the interest in such property, there was a significant (a) change in the type or frequency of aircraft operations at the airport, (b) change in the airport layout, (c) change in flight patterns, or (d) increase in nighttime operations; and (2) that damages have resulted from any such change or increase.
