Denver/Adams County IGA
- 1988 Agreement to limit noise exposure in surrounding
areas of Adams County.
- Established “NEPS” (Noise Exposure Performance Standards)
at 101 geographic points and along the FEIS 65 DNL
boundary.
- Noise limits are based upon Annual L eq (except for Annual
DNL on the contour). Most limits are set in the low 30dB to
mid 40dB range, below ambient noise levels and well below
federal standards for residential compatibility.

Denver/Adams County IGA (cont.)
- Airport may be fined $500,000 per violation, per year at
each NEPS point (or contour) if violations of NEPS limits are
not remedied.
- Although DEN has 27 remote noise monitors installed, NEPS
compliance is calculated using the ARTSMAP noise model.
Every flight track for every operation is modeled.
- Modeling is used to ensure that non-DEN aircraft noise is
excluded from the calculation. Modeling also ensures that
we obtain the most complete picture of the noise
environment, free from meteorological and community noise
effects.

DEN Noise Environment – 9/11/01
- DEN Noise Office examined measured noise levels at remote
noise monitors on 9/11 and 9/12 of 2001. Levels were
compared to corresponding days one week earlier, 9/4 and
9/5.
- No civilian aircraft operated after approximately 8:00am
local time on 9/11, nor at any time on 9/12.
- Of the 29 noise monitor sites in operation, 10 recorded noise
levels > 0.5 dB higher on 9/12 than on 9/5, 13 recorded
levels > 0.5 dB lower on 9/12, and 6 sites were virtually the
same. Similar results were observed on 9/11.
- L 10 levels (louder noise events) were higher on 9/12 at 12
sites, lower at 15 sites, and the same at the remaining two.
