A BILL FOR

 

HB5520LRB101 18230 LNS 70238 b

1    AN ACT concerning transportation.
 
2    Be it enacted by the People of the State of Illinois,
3represented in the General Assembly:
 
4    Section 5. The Permanent Noise Monitoring Act is amended by
5changing Sections 5 and 15 as follows:
 
6    (620 ILCS 35/5)  (from Ch. 15 1/2, par. 755)
7    Sec. 5. Definitions. As used in this Act:
8    (a) "Airport" means an airport, as defined in Section 6 of
9the Illinois Aeronautics Act, that has more than 500,000
10aircraft operations (take-offs and landings) per year.
11    (a-1) "Airport sponsor" means any municipality, as defined
12in Section 20 of the Illinois Aeronautics Act, that can own and
13operate an airport.
14    (a-3) "Annual community noise equivalent level" or "annual
15CNEL" means the average sound level (on an energy basis), in
16decibels, of the daily community noise equivalent level over a
1712-month period. The annual CNEL is calculated by the
18following:
 
19
Annual CNEL = 10 log 10 [(1/365) SIGMA antilog (CNEL(i)/10)]

 
20Where:
21        (1) CNEL(i) = the daily CNEL for each day in a

 

 

HB5520- 2 -LRB101 18230 LNS 70238 b

1    continuous 12-month period; and
2        (2) SIGMA means summation.
3    When the annual CNEL is approximated by measurements on a
4statistical basis, the number 365 is replaced by the number of
5days for which measurements are obtained.
6    (a-5) "Daily community noise equivalent level" or "CNEL"
7means the 24-hour day average sound level, in decibels,
8adjusted to an equivalent level to account for the lower
9tolerance of people to noise during evening and night time
10periods relative to the daytime period. The daily community
11noise equivalent level is calculated from the hourly noise
12levels by the following:
 
13
CNEL = 10 log (1/24) [SIGMA antilog (HNLD/10) + 3 SIGMA antilog
14
(HNLE/10) + 10 SIGMA antilog (HNLN/10)]

 
15Where:
16        (1) HNLD means the hourly noise levels for the period
17    7:00 a.m. through 6:59 p.m.;
18        (2) HNLE means the hourly noise levels for the period
19    7:00 p.m. through 9:59 p.m.;
20        (3) HNLN means the hourly noise levels for the period
21    10:00 p.m. through 6:59 a.m.; and
22        (4) SIGMA means summation.
23    (a-7) "Noise annoyance levels" means levels derived from
24data compiled using the noise annoyance protocol proposed by

 

 

HB5520- 3 -LRB101 18230 LNS 70238 b

1members of the International Commission on Biological Effects
2of Noise and adopted by ISO TS 15666, which is hereby
3incorporated by reference.
4    (a-8) "Noise exposure level" means the level, in decibels,
5of the time-integrated A-weighted squared sound pressure for a
6stated time interval or event, based on the reference pressure
7of 20 micronewtons per square meter and reference duration of
8one second.
9    (a-9) "Noise level" means the sound level measure, in
10decibels, of an A-weighted sound pressure level as measured
11using the slow dynamic characteristic for sound level meters
12specified in American National Standard Specification for
13Sound Level Meters (ANSI S1.4-1983 as revised by ANSI
14S1.4A-1985), which is hereby incorporated by reference. The
15A-weighting characteristic modifies the frequency response of
16the measuring instrument to account approximately for the
17frequency characteristics of the human ear. The reference
18pressure is 20 micronewtons/square meter (2 x 10-4 microbar).
19    (b) "Permanent noise monitoring system" or "system" means a
20system that includes at least:
21        (1) automated noise monitors capable of recording
22    noise levels 24 hours per day 365 days per year; and
23        (2) computer equipment sufficient to process the data
24    from each noise monitor so that permanent noise monitoring
25    reports in accordance with Section 15 of this Act can be
26    generated.

1    (c) "Division" means the Division of Aeronautics of the
2Illinois Department of Transportation.
3    (d) (Blank).
