January 1st to June 30th, 2008 Cumulative Results
The number of potential Class II NEPS violations registered during January 1st through
June 30th, 2008 is zero. During January 1st through June 30th, 2007, there were also
zero potential Class II NEPS violations. Please see page 8 for DEN NEPS information.
Inside this issue:
There was no potential 65 DNL noise contour violation for the time period. The 65
DNL contour continued to be completely contained within the boundaries of the City and DEN ANOMS 2
County of Denver. Please see page 7 for DEN contour map.
There was a 5% decrease in noise complaints received in the first 6 months of 2008 ARTSMAP 2
as compared to the same period in 2007 (454 vs. 477 in 2007). The number of house-
holds registering at least one complaint increased by 23% (6O vs. 46 in 2OO7). Five Land Use and Zoning 2
households registered a combined 56% of total complaints. The percentage of com- DEN Noise Hotline Policy 3

Departures
` `1 Total for June 2nd = 889
DIA's six runways provide a multitude of op-
tions when departing/landing aircraft. Wind
plays a key role in these operations. As wind
shifts throughout the day, so does the runway
usage. One minute aircraft could be departing
Y ° to the West and the next to the South. These

the region.

like departures, arrivals need to land into the

changes.
Non-DIA Traffic
- y: r
Total for June 2nd = 833
Many flights originate from the various airports
# around the metro area. These include Buckley
Air Force Base, Centennial Airport, Front
Range Airport, and Rocky Mountain Metropoli-
tan Airport. These flights cover a wide range
• of aircraft types and altitudes. These can in-
clude medical, training, and business flights.
As you can see these flights are typically routed
away from DIA airspace.
