If you have any questions regarding this report, or if I can be of further assistance, please contact me at (303) 342-2360. Sincerely, Andrea C. Christensen Denver International Airport Aviation Noise Officer DENVER INTERNATIONAL AIRPORT Department of Aviation Airport Office Building 8500 Pena Boulevard Denver,Colorado 80249 303.342.2200 www.FlyDenver.com it/ / r ( c A/'re Ai l i7 G c7w),y // 2008-0754 C-)7-0 -c€ 42.4& Issued: January 31, 2008 January 1—December 31, 2007 Results The number of potential Class II NEPS violations registered during 2007 is one. This potential Class II NEPS violation occurred in AREA 3 at E, -1. The poten- tial Class II NEPS violation for 2006 also occurred in AREA 3 at E, -1. Please see page 7 for DEN NEPS information. There was no potential 65 DNL noise contour violation for the quarter. The 65 DNL contour continued to be completely contained within the boundaries of the City and County of Denver. Please see page 6 for DEN contour map. CD There was a 33% increase in noise complaints received in 2007, as compared p to the same period in 2006 ( 1072 vs. 713). Five households registered a com- bined 46% of total complaints with 82 households registering complaints. There was a decrease of 57% in households registering complaints in 2007 compared to 2006 (82 vs. 145). The percentage of complaints received during Nighttime CD Aircraft Operations ( 10:00pm to 7:00am) for 2007 was 13% of all complaints re- PIz.h.4 I 0 O ceived. Please see pages 8 - 10 for complete complaint and operational data . Cn, � * ( Don 't) Go West Young Man? Oi In order to reduce noise impact west of DIA and to ensure compliance with O Z NEPS limits in NEPS Area 2, in 1995 DIA in cooperation with the airlines and the •...• FM implemented a westbound noise abatement departure procedure. This pro- tt LY cedure was designed to address the disproportionate noise impact caused by the noisiest aircraft in the fleet by diverting them away from noise sensitive areas to the west. While many of these older noisier aircraft were ultimately retired, today %,) CTS there are still a relatively small number of older aircraft that generate much more t = noise than current generation designs do. CTo continue efforts to reduce noise impact west of the airport, the westbound o) procedure was revised several years ago to include so-called " Noise-Critical Air- ? C craft." The most common of these aircraft at DIA is the MD-80. A single MD-80 y on departure has the same overall noise impact as the combined noise from q ICCroughly 100 current generation aircraft, like the Airbus A-320 or the Boeing 737- 800. Because of this disproportionate impact, the DIA Noise Abatement Office Nal continues to solicit greater compliance with the procedure, and to encourage air- lines to accelerate retirement of Noise Critical Aircraft as soon as possible. ille CN1 Inside this issue: Special points of interest: DEN ANOMS 2 ARTSMAP 2 • One Possible NEPS Violation for Jan—Dec, 2007. _ - - Land Use and Zoning 2 • Complaints are up 33% from 2006.
