AMENDMENTS TO 35 ILL. ADM. ) (Rulemaking - Noise)
CODE 900 AND 903 )
Proposed Rule. Proposal for Public Comment.
ORDER OF THE BOARD (by M.E. Tristano):
Pursuant to 35 Ill. Adm. Code Part 102 Subpart B and Sections 27 and 28 of the Illinois Environmental Protection Act, 415 ILCS 5/27-5/28 (2000), the Illinois Pollution Control Board opened this rulemaking to amend and update the Board’s noise rules.
The noise rules affected are set forth at 35 Ill. Adm. Code 900 and 903. These are general provisions dealing with the definitions of acoustical terminology, prohibition against noise pollution, and sound measurement procedures. The proposed changes involve the updating of definitions and sound measurement procedures. These definitions and measurement procedures were adopted in 1973 and have not been amended or changed since then. The basis for these changes is the American National Standards Institute updates from the years 1998-2001.
The Board also proposes to repeal Part 903, which specifies rules and regulations for the control of noise from motor racing facilities. Since the adoption of these rules, Section 25 of the Environmental Protection Act has been modified to exclude organized sporting events, including motor racing facilities from the Board’s noise regulations.
The Board adopts this proposal for public comment. The Board intends to hold two hearings on the proposal, one in Chicago and one in Springfield. Interested persons are encouraged to contact the hearing officer to be added to the notice list in this docket.

Section 903.121 Sound Level Measurement Requirements
a) | The sound emissions from each drag racing vehicle required to have a muffler in accordance with Section 903.120 must be measured before competing in terms of A-weighted sound levels using sound level meters in conformance with American National Standards Institute (ANSI) Standards §1.4 Type 1 or Type 2 requirements and using procedures specified in 35 Ill. Adm. Code 900.103. All sound level measurements must be made with the microphone one-half meter from the exhaust outlet with the engine gear-box in neutral at an engine speed of 4000 rpm. It shall be the responsibility of the drag racing facility's owners or operators, or designated agent, to measure and record the required sound level data. Upon reasonable request, the owner or operator shall make such recorded sound level data available to the Agency. The owner and operator must keep such recorded sound level data for the duration of the racing season. |
b) | The Agency shall publish techniques for determining compliance with Section 903.120 under static test conditions. |
c) | On and after March 15, 1979, before any motorcycle racing vehicle required to have a muffler in accordance with Section 903.120 competes at a drag racing facility, the noise emissions from such motorcycle racing vehicle must be measured in terms of A-weighted sound levels using sound level meters in conformance with ANSI Standards §1.4 Type 1 or Type 2 requirements and using procedures specified in 35 Ill. Adm. Code 900.103. The microphone shall be located one-half meter from and in the horizontal plane of the rearmost exhaust outlet at an angle of 45 degrees behind the exhaust outlet and from the normal line of travel of the motorcycle. The engine shall be run with the gear-box in neutral at an engine speed equal to one-half of the manufacturer's-recommended-maximum-engine-speed. If no manufacturer's-recommended- maximum-engine-speed is published for a particular motorcycle, then an engine speed equal to 60 percent of the engine speed at which maximum horsepower is developed shall be used. If no manufacturer's-recommended-maximum-engine-speed is published, then the engine speed during the sound level measurement shall be calculated from either of the following formulae: |
Engine Speed = 306,000
stroke in millimeters
OR
Engine Speed = 12,000
stroke in inches
Section 903.122 Sound Emission Limits
On and after March 15, 1979, no person shall cause or allow the use or operation of any motorcycle racing vehicle required to have a muffler in accordance with Section 903.120 whose sound emissions exceed 115 db(A) when measured in accordance with Section 903.121 and when measured one-half meter from the rearmost exhaust outlet.
SUBPART C: OVAL RACING FACILITIES
Section 903.140 Muffler Requirements
a) | Except as provided in subparagraph (b), no person shall cause or allow the use or operation of any oval racing vehicle at an oval racing facility unless such oval racing vehicle is equipped with a well-maintained and properly installed muffler. Except for any motorcycle used as an oval racing vehicle, all mufflers required in accordance with this rule shall meet the requirements specified in subparagraph (c). |
b) | The following oval racing vehicles shall not require a muffler in accordance with subparagraph (a); |
1) Sprint racing vehicles;
2) Midget racing vehicles;
3) Supercharged oval racing vehicles.
c) | Except for any motorcycle used as an oval racing vehicle, all mufflers required in accordance with subparagraph (a) shall have noise reducing characteristics which will produce a reduction in total vehicle noise of at least the amount listed in the following table when such oval racing vehicle is operated in a manner simulating wide-open throttle competition. Such noise reduction shall be determined by using measurement procedures specified in 35 Ill. Adm. Code 900.103. |

b) | The Agency shall publish techniques for determining compliance with Section 903.140 under static test conditions. |
c) | The requirements for measuring noise emissions from motorcycle racing vehicles competing at oval racing facilities shall be identical to those specified under Section 903.121(c) for motorcycle racing vehicles competing at drag racing facilities. |
Section 903.142 Sound Emission Limits
No person shall cause or allow the use or operation of any motorcycle racing vehicle required to have a muffler in accordance with Section 903.140 whose sound emissions exceed 115 dB (A) when measured in accordance with Section 903.141 and when measured one-half meter from the rearmost exhaust outlet.
SUBPART D: SPORTS CAR RACING FACILITIES
Section 903.160 Muffler Requirements
a) | Except as provided in subparagraph (b), on and after March 15, 1979, no person shall cause or allow the use or operation of any sports car racing vehicle competing at a sports car racing facility unless such sports car racing vehicle is equipped with a well-maintained and properly installed muffler. |
b) | The following sports car racing vehicles shall not require a muffler in accordance with subparagraph (a): all sports car racing vehicles which are supercharged. |
Section 903.161 Sound Level Measurement Requirements
During all qualifying runs, noise emissions from each sports car racing vehicle required to have a muffler in accordance with Section 903.160, must be measured in terms of A-weighted sound levels using sound level meters in conformance with ANSI Standards §1.4 Type 1 or Type 2 requirements and using procedures specified in 35 Ill. Adm. Code 900.103. All measurements must consistently be made at the same measurement site; provided, however, that such measurement site can be changed if necessitated by good faith circumstances making the use of the first measurement site impossible or impractical. It shall be the responsibility of the sports car racing facility's owners or operators, or designated agent, to measure and record the required sound level data. Upon reasonable request, the owner or operator shall make such recorded sound level data available to the Agency. The owner and operator must keep such recorded sound level data for the duration of the racing season.
