A BILL FOR
HB5520 LRB101 18230 LNS 70238 b
AN ACT concerning transportation.
Be it enacted by the People of the State of Illinois,
represented in the General Assembly:
Section 5. The Permanent Noise Monitoring Act is amended by
changing Sections 5 and 15 as follows:
(620 ILCS 35/5) (from Ch. 15 1/2, par. 755)
Sec. 5. Definitions. As used in this Act:
(a) "Airport" means an airport, as defined in Section 6 of
the Illinois Aeronautics Act, that has more than 500,000
aircraft operations (take-offs and landings) per year.
(a-1) "Airport sponsor" means any municipality, as defined
in Section 20 of the Illinois Aeronautics Act, that can own and
operate an airport.
(a-3) "Annual community noise equivalent level" or "annual
CNEL" means the average sound level (on an energy basis), in
decibels, of the daily community noise equivalent level over a
12-month period. The annual CNEL is calculated by the
following:
Annual CNEL = 10 log 10 [(1/365) SIGMA antilog (CNEL(i)/10)]
Where:
(1) CNEL(i) = the daily CNEL for each day in a

HB5520 - 2 - LRB101 18230 LNS 70238 b
continuous 12-month period; and
(2) SIGMA means summation.
When the annual CNEL is approximated by measurements on a
statistical basis, the number 365 is replaced by the number of
days for which measurements are obtained.
(a-5) "Daily community noise equivalent level" or "CNEL"
means the 24-hour day average sound level, in decibels,
adjusted to an equivalent level to account for the lower
tolerance of people to noise during evening and night time
periods relative to the daytime period. The daily community
noise equivalent level is calculated from the hourly noise
levels by the following:
CNEL = 10 log (1/24) [SIGMA antilog (HNLD/10) + 3 SIGMA antilog
(HNLE/10) + 10 SIGMA antilog (HNLN/10)]
Where:
(1) HNLD means the hourly noise levels for the period
7:00 a.m. through 6:59 p.m.;
(2) HNLE means the hourly noise levels for the period
7:00 p.m. through 9:59 p.m.;
(3) HNLN means the hourly noise levels for the period
10:00 p.m. through 6:59 a.m.; and
(4) SIGMA means summation.
(a-7) "Noise annoyance levels" means levels derived from
data compiled using the noise annoyance protocol proposed by

HB5520 - 3 - LRB101 18230 LNS 70238 b
members of the International Commission on Biological Effects
of Noise and adopted by ISO TS 15666, which is hereby
incorporated by reference.
(a-8) "Noise exposure level" means the level, in decibels,
of the time-integrated A-weighted squared sound pressure for a
stated time interval or event, based on the reference pressure
of 20 micronewtons per square meter and reference duration of
one second.
(a-9) "Noise level" means the sound level measure, in
decibels, of an A-weighted sound pressure level as measured
using the slow dynamic characteristic for sound level meters
specified in American National Standard Specification for
Sound Level Meters (ANSI S1.4-1983 as revised by ANSI
S1.4A-1985), which is hereby incorporated by reference. The
A-weighting characteristic modifies the frequency response of
the measuring instrument to account approximately for the
frequency characteristics of the human ear. The reference
pressure is 20 micronewtons/square meter (2 x 10-4 microbar).
(b) "Permanent noise monitoring system" or "system" means a
system that includes at least:
(1) automated noise monitors capable of recording
noise levels 24 hours per day 365 days per year; and
(2) computer equipment sufficient to process the data
from each noise monitor so that permanent noise monitoring
reports in accordance with Section 15 of this Act can be
generated.

HB5520 - 4 - LRB101 18230 LNS 70238 b
(c) "Division" means the Division of Aeronautics of the
Illinois Department of Transportation.
(d) (Blank).

(620 ILCS 35/15) (from Ch. 15 1/2, par. 765)
Sec. 15. Permanent noise monitoring reports. Beginning in
1993 and through 2008, the Division shall, on June 30th and
December 31st of each year, prepare a permanent noise
monitoring report and make the report available to the public.
Beginning in 2009, the airport sponsor shall, on June 30th and
December 31st of each year, prepare a permanent noise
monitoring report and make the report available to the public.
Copies of the report shall be submitted to: the Office of the
Governor; the Office of the President of the Senate; the Office
of the Senate Minority Leader; the Office of the Speaker of the
House; the Office of the House Minority Leader; the United
States Environmental Protection Agency, Region V; and the
Illinois Environmental Protection Agency. Beginning in 2009, a
copy of the report shall also be submitted to the division.
Beginning in 2021, the permanent noise monitoring report shall
track noise annoyance levels as defined in subsection (a-7) of
Section 5. The permanent noise monitoring report shall contain
all of the following:
(a) Copies of the actual data collected by each permanent
noise monitor in the system.

HB5520 - 5 - LRB101 18230 LNS 70238 b
(b) A summary of the data collected by each permanent noise
monitor in the system, showing the data organized by:
(1) day of the week;
(2) time of day;
(3) week of the year;
(4) type of aircraft; and
(5) the single highest noise event recorded at each
monitor.
(c) Noise contour maps showing the 65 annual CNEL, 70
annual CNEL and 75 annual CNEL zones around the airport.
(d) Noise contour maps showing the 65 decibel (dBA), 70
dBA, and 75 dBA zones around the airport for:
(1) 7:00 a.m. through 6:59 p.m.;
(1.5) 7:00 p.m. through 9:59 p.m.;
(2) 10:00 p.m. through 6:59 a.m.; and
(3) types of aircraft.
(e) The noise contour maps produced under subsections (c)
and (d) shall also indicate:
(1) residential areas (single and multi-family);
(2) schools;
(3) hospitals and nursing homes;
(4) recreational areas, including but not limited to
parks and forest preserves;
(5) commercial areas;
(6) industrial areas;
(7) the boundary of the airport;

(9) the number of residents within each contour;
(10) the number of schools within each contour; and
(11) the number of school students within each contour.
(f) Through 2008, a certification by the Division that the
