99TH GENERAL ASSEMBLY
State of Illinois
2015 and 2016
HB1340

 

Introduced 2/4/2015, by Rep. Martin J. Moylan

 

SYNOPSIS AS INTRODUCED:
 
620 ILCS 35/5  from Ch. 15 1/2, par. 755
620 ILCS 35/15  from Ch. 15 1/2, par. 765

    Amends the Permanent Noise Monitoring Act. Deletes the definition of "Ldn". Defines "Annual community noise equivalent level" or " annual CNEL", "daily community noise equivalent level" or "CNEL", "noise exposure level", and "noise level". Requires permanent noise monitoring reports to include noise contour maps showing the 65 CNEL, 70 CNEL, and 75 CNEL zones (instead of "65 Ldn, 70 Ldn and 75 Ldn zones") around the airport. Makes corresponding changes.

A BILL FOR

 

HB1340LRB099 06140 RJF 26196 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

 

 

HB1340- 2 -LRB099 06140 RJF 26196 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-8) "Noise exposure level" means the level, in decibels,
24of the time-integrated A-weighted squared sound pressure for a

 

 

HB1340- 3 -LRB099 06140 RJF 26196 b

1stated time interval or event, based on the reference pressure
2of 20 micronewtons per square meter and reference duration of
3one second.
4    (a-9) "Noise level" means the sound level measure, in
5decibels, of an A-weighted sound pressure level as measured
6using the slow dynamic characteristic for sound level meters
7specified in American National Standard Specification for
8Sound Level Meters (ANSI S1.4-1983 as revised by ANSI
9S1.4A-1985), which is hereby incorporated by reference. The
10A-weighting characteristic modifies the frequency response of
11the measuring instrument to account approximately for the
12frequency characteristics of the human ear. The reference
13pressure is 20 micronewtons/square meter (2 x 10-4 microbar).
14    (b) "Permanent noise monitoring system" or "system" means a
15system that includes at least:
16        (1) automated noise monitors capable of recording
17    noise levels 24 hours per day 365 days per year; and
18        (2) computer equipment sufficient to process the data
19    from each noise monitor so that permanent noise monitoring
20    reports in accordance with Section 15 of this Act can be
21    generated.
22    (c) "Division" means the Division of Aeronautics of the
23Illinois Department of Transportation.
24    (d) (Blank). "Ldn" means day-night average sound level.
25"Day-night average sound level" has the meaning ascribed to it
26in Section 150.7 of Part 150 of Title 14 of the Code of Federal
