Proposed Rule. Second First Notice.
 
OPINION AND ORDER OF THE BOARD (by G.T. Girard):
 
Pursuant to Sections 27 and 28 of the Illinois Environmental Protection Act (Act), (415
ILCS 5/27-5/28 (2002)) and 35 Ill. Adm. Code 102.Subpart B, on February 20, 2003, the Board
opened this rulemaking to propose updated regulations governing noise found in 35 Ill. Adm.
Code Subtitle H. Many of the sound measurement definitions and techniques in the Board’s
current rules do not reflect present scientific standards. The instant proposal revises outdated
numerical sound emission standards for property line noise sources found at 35 Ill. Adm. Code
901. In addition, the proposal adds Part 910 to the Board’s rules that incorporates noise
measurement techniques currently contained only in Illinois Environmental Protection Agency
(Agency) rules at 35 Ill. Adm. Code 951.
 
BACKGROUND
 
The Board’s noise rules were updated in 1983 and again in 1987. In 1990, the
Department of Energy and Natural Resource
1
(DENR) contracted Dr. Paul Schomer of the
University of Illinois to examine the adequacy of Illinois noise regulations, and, particularly
whether the existing rules were adequate to regulate discontinuous noise. Dr. Schomer’s report,
“Impulse Noise Study,” (ILENR/RE-EA-90-16, printed November 1990, Springfield, IL)
suggested some adjustments in the Board’s noise regulations. In 1991, DENR contracted for an
additional report by Dr. Schomer, entitled, “Proposed Revisions to Property Line Noise Source:
Measurement Procedures”, (ILENR/RE-EA-91/10, printed June 1991, Springfield, IL),
describing and developing a systematic set of procedures for noise measurements.
 
During the summer of 1991, the Board prepared a proposal that attempted to translate the
Schomer reports into regulatory language (Amendments to 35 Ill. Adm. Code Subtitle H Noise-
Pertaining to Definitions, Measurement Procedures, and Sound Emission Standards Relating to
Certain Noise Sources, R91-25 (Oct. 24, 1991)). An inquiry hearing based on the document was
held on November 25, 1991, in Chicago. The Board’s proposal was based on revising the noise
measurement procedures at Section 900.103(b) and the impulsive sound standards at Section
901.104. In addition, the Board proposed incorporating Agency noise measurement procedures
1
In 1995, P.A. 89-50 (eff. July 1, 1995) (20 ILCS 5/801
et seq
. (2002)) merged DENR into the
Department of Natural Resources.

 
2
found at 35 Ill. Adm. Code 951 into Board regulations at 35 Ill. Adm. Code 910, by modifying
the Part 951 language to incorporate the recommendations contained within the Schomer reports.
In 1992, the Board closed the R91-25 docket before proceeding to first notice with proposed
changes to the Board’s noise rules.
 
The need to update the Board’s noise rules to conform to current scientific procedures has
become more apparent during the past ten years. The Board has identified necessary
improvements in several areas. In the instant rulemaking, the Board proposes changes in Part
901 and the addition of Part 910. In Part 901, the Board proposes to replace the references to the
Standard Land Use Coding System (SLUCM) codes with the more appropriate Land-Use Based
Classification System. New rules in Part 910 are proposed to incorporate Agency noise
measurement procedures found at 35 Ill. Adm. Code 951.
 
PROCEDURAL HISTORY
 
The Board opened this rulemaking by issuing a draft for public comment on February 20,
2003. The Board elicited comments on the draft prior to first notice publication from the public
and those involved in prior rulemakings involving noise regulation. Individuals who were on the
notice list were sent drafts and the hearing dates. In addition, the proposed rule and the notice of
hearings were posted on the Board’s website. The Board held two hearings in this matter after
the proposal for public comment was distributed, before Hearing Officer William F. Murphy.
The first was held in Springfield on May 1, 2003; no members of the public attended that
hearing. The second hearing (Tr.2) was held in Chicago on May 15, 2003. Joel Sternstein and
Howard Chinn of the Illinois Attorney General’s Office (AGO) attended the second hearing and
Mr. Chinn presented testimony. During the time that the proposal was offered for public
comment, the Board received two public comments, one from the AGO (PC 2) and one from Dr.
Paul Schomer (PC 1).
 
On July 10, 2003, the Board proposed the rule for first notice. On July 25, 2003, the first
notice was published in the
Illinois Register
(27 Ill. Reg. 11908). The Board received five public
comments. The comments were from Scot Forge (PC 3), Vaughan and Bushnell Manufacturing
(PC 4), Illinois Association of Aggregate Producers (IAAP) (PC 5), Boughton Trucking and
Materials Inc. (Boughton Trucking) (PC 6) and Intermet Decatur Foundry (Intermet) (PC 7). In
general, the comments requested a site-specific rule modification or requested another hearing to
discuss concerns with the proposed rule.
 
On October 18, 2003, the Board determined that additional hearings should be held.
After holding an additional hearing, the Board determined on March 4, 2004, that administrative
economy supported including site-specific changes in a new first notice. Because of these
decision, the Board withdrew the first notice (
See
28 Ill. Reg. 7341, 7342 (May 21, 2004)).
 
The Board held two additional hearings before Board Hearing Officer Marie Tipsord.
The third hearing (Tr.3) was held February 10, 2004, in Chicago. At that hearing, Mr. John P.
McGillivray testified on behalf of Scot-Forge Company and Howard Chinn testified on behalf of
the AGO. The fourth hearing (Tr.4) was held November 4, 2004, in Springfield. Mr. John
Henriksen and Dane Tittman testified on behalf of the IAAP.

 
3
 
The Board received an additional six comments during the second phase of hearings.
The comments were from Moline Forge (PC 8), Intermet (PC 9, IAAP (PC 10), the AGO (PC
11), Village of Bridgeview (Bridgeview) (PC 12), and the Illinois Department of Natural
Resources (IDNR) (PC 13).
 
PRE-FIRST NOTICE COMMENTS
 
Dr. Paul Schomer filed a comment questioning the Board’s language in Sections 910.106
and 910.107. Dr. Schomer indicated that the language was nearly identical to the language
contained in ANSI S12.9 Part 3-1998 (R2003) (ANSI standard). Dr. Schomer stated that the
material in ANSI standard was copyrighted material and asked that the language be removed. In
response to the comment, the Chairman of the Board (by a letter dated March 21, 2003 and
included in the record of this proceeding) notified Dr. Schomer that the language as used in
Section 910.106 and 910.107 was based on language included in an Illinois Department of
Energy and Natural Resource’s study
Proposed Revisions to Property Line Noise Source:
Measurement Procedures
(ILENR/RE-ES-91/10). The Chairman’s letter pointed out that the
study was published in 1991 and that the materials were included in a prior public record. The
Board therefore declined to remove the language.
 
The AGO filed a comment and provided testimony. In the comment, the AGO applauded
the Board’s decision to update the amendments to the noise rules. PC 1 at 1. The AGO
indicated that the updating of the noise rules is a significant regulatory update that will provide a
statewide uniform program for noise pollution enforcement by state and local governments.
Id
.
The AGO suggests adopting a five-minute measurement period rather than the current one-hour
measurement period. PC 1 at 2.
 
Mr. Chinn, chief engineer for the Environmental Bureau of the AGO, made two points.
First, he testified that the regulations should explicitly state that one-hour averaging and an
integrating meter are not required. Tr.2 at 9. Second, Mr. Chinn suggested that the Board set
statewide regulations to limit the hours of operations for all types of lawn care equipment and set
limits on the sound levels for the equipment. Tr.2 at 9, 13.
 
FIRST NOTICE
 
The participants in this rulemaking raised a number issues concerning the proposed
amendments after the publication of the first notice opinion and order on July 10, 2003
(Proposed New and Updated Rules for Measurement and Numerical Sound Emissions Standards;
Amendments to 35 Ill. Adm. Code 901 and 910, R03-9 (July 10, 1003)). These issues concerned
the qualification of sound monitoring personnel, sound measurement procedures for establishing
nuisance noise violation, numerical noise standard for highly impulsive sound from blasting
operations as it applies to aggregate industry, and forging industry site-specific regulations. The
testimony and comments presented by the participants are summarized below along with the
Board findings.
 
Sound Monitoring Personnel Qualifications

 
4
 
The IAAP, Bridgeview and Boughton Trucking expressed concerns regarding the lack of
qualification requirements for personnel conducting sound measurements to show compliance
with the standards of 35 Ill. Adm. Code 900 and 901. IAAP, the trade association representing
companies that produce crushed stone, sand, gravel, silica sand, etc. filed comments and testified
before the Board on the issue of qualification requirements. Tr.4 at 5. IAAP states that although
35 Ill. Adm. Code 951.101 sets forth qualifications for Agency personnel who conduct sound
measurements, the new Part 910 does not include similar requirements for non-Agency
personnel. PC 5 at 2. IAAP contends that although there is no State approved licensing or
certification process for personnel who conduct sound measurements, the Board should
incorporate requirements similar to the Agency rules under Part 910.
Id
. IAAP recommends
that the Board add a new section 910.101 as follows:
 
Personnel who conduct sound measurements in order to show compliance with
the Board’s noise standards in Part 900 and 901 must be trained and experienced
in the current techniques and principles of sound measurement and in the
selection and operation of sound measuring instrumentation.
 
Bridgeview and Boughton Trucking share IAAP’s concerns regarding the qualifications
requirements for personnel who conduct sound measurements. PC 6 and PC 12 at 1-2.
Bridgeview states that it concurs with IAAP’s position “that sound measurements gathered by
anyone without some basic level of training and experience are of questionable validity and
should not be considered as valid evidence of noise levels by this Board or by a court of
competent jurisdiction.” PC 12 at 2. Further, Bridgeview agrees with IAAP that sound
measurements used a corroborating evidence in nuisance cases must be collected in accordance
with the detailed sound measurement procedures set forth at 35 Ill. Adm. Code 910.105 or
951.104.
Id
. Both Bridgeview and Boughton Trucking support the alternative language
submitted by IAAP.
 
Discussion
 
The commenters raise a valid concern regarding the qualifications of personnel
conducting sound monitoring to show compliance with the noise standards set forth at 35 Ill.
Adm. Code 900 and 901. The Board recognizes that based on the complexity of the
instrumentation used and the nature of the sound source, the validity of sound measurement data
depends on the training and experience of the personnel in current techniques and principles of
sound measurement. In this regard, the Board routinely determines the validity of sound
measurement data in noise enforcement cases based on the qualifications of the person
conducting sound measurement. In making such determinations, the Board relies on sworn
expert testimony and a comprehensive record developed through a public hearing process.
 
The Board finds that the present regulatory structure, where the Board determines the
validity of sound data on a case-by-case basis in noise enforcement cases, is a more prudent
approach than prescribing vague qualification requirements. The Board believes this is
especially true absent a State approved licensing or certification process. Although the
qualification requirements proposed by IAAP is derived from an Agency regulation under Part

 
5
951, the proposed language lacks specificity and does not provide any additional guidance to the
Board in making its determination. In light of this, the Board declines to add the qualification
requirement proposed by IAAP.
 
Sound Measurement Procedures for Establishing Nuisance Noise Violation
 
IAAP and the Bridgeview assert that techniques for sound measurements used as
corroborating evidence in establishing nuisance noise violation must be done in accordance with
procedures of Section 910.105. PC 5 at 2; PC 12 at 2. IAAP notes that the proposed
measurement techniques applicable to nuisance noise at Section 910.104 do not require sound
measurements used for establishing nuisance violation to be gathered in accordance with the
procedures of Section 910.105, but allows such procedures to be used as guidance. Thus, IAAP
maintains that the proposal at Section 910.104 compounds the problems created by lack of
qualification requirements for personnel who conduct sound measurements. PC5 at 3.
Bridgeview agrees with IAAP’s position and supports the following amendments proposed by
IAAP to Section 910.104 (PC 12 at 2-3):
 
Sound pressure level measurements are not required to establish a violation of 35
Ill. Adm. Code 900.102 (nuisance noise). However, sound pressure level
measurements may be introduced as corroborating evidence when alleging a
violation of35 III. Adm. Code 900.102. If sound pressure level measurements are
collected, manufacturer’s instructions must be followed for the equipment used
and 35 Ill. Adm. Code 910.105 may be used as guidance in gathering data. In
addition, sound measurements used to establish a violation of 35 Ill. Adm. Code
900.102 must be obtained in accordance with either:
 
a) 35 Ill. Adm. Code 910.105; or
 
b) 35 Ill. Adm. Code 951.104.
 
Discussion
 
Section 910.104 clarifies that sound pressure level measurements are not required to
establish a violation of the Board’s nuisance noise standard at Section 900.102, although such
measurements may be used as corroborating evidence. In light of this, the Board finds that
compliance with the detailed sound measurement procedures set forth in Part 951 or the
proposed Part 910 are not required for sound measurements used as corroborating evidence in a
nuisance noise proceeding. The Board will assign appropriate weight to sound measurement
data submitted in any nuisance noise complaint based on the information in the hearing record
and in accordance with the provisions of the Act. As noted in the first first-notice opinion
(Proposed New and Updated Rules for Measurement and Numerical Sound Emissions Standards;
Amendments to 35 Ill. Adm. Code 901 and 910, R03-9 (July 10, 1003)), the Board believes that
this approach is consistent with the Board’s precedence and case law concerning nuisance noise
complaints. The Board declines to make the changes suggested by IAAP.
 
Numerical Noise Standard for Highly Impulsive Sound from Blasting Operations

 
6
 
IAAP expressed concerns regarding the existing standards for highly-impulsive sound
from explosive blasting at Section 901.109. Mr. John Henriksen, Executive Director of IAAP,
testified that blasting operations at aggregate production sites are regulated by the IDNR in
accordance with Section 6.5 of the Surface Mined-Land Conservation and Reclamation Act (215
ILCS 715/6.5). Tr.4 at 5 and PC 10 at 1. Mr. Henriksen stated that the industry and IDNR
“employ highly trained personnel to conduct air and . . . air blast and ground vibration
monitoring as required by the State law.” Tr.4 at 6. He noted that although blasting operations
are regulated by IDNR, IAAP members are also subject to the Board’s noise regulations.
Id
.
 
Mr. Henriksen noted that the numerical noise standard for highly impulsive sound from
blasting operations at Section 901.109 should be revised to reflect the IDNR standard. While the
IDNR regulation specifies a standard of 133 decibels at 2 Hertz instrument limit, the current
Board regulations at Section 901.109 sets forth a standard of 132 decibels for Class A land and
137 decibels for Class B land. Mr. Tittman with Vibra-Tech Engineers testified that most
modern seismographs used for monitoring blasting operations have low frequency response of
2.0 Hertz. Tr.4 at 16. Further he noted that the limit established by IDNR at this frequency is
133 decibels, which is based on a study by U.S. Bureau of Mines.
Id
. Mr. Tittman stated that
the 133 decibels limit is employed nationally to regulate explosive blasting. He also suggested
that the Board delete the standards set forth at Section 901.109 for frequency limit less than 01.
Hertz and less than 6.0 Hertz. Tr.4 at 41. Mr. Tittman stated that instruments with 0.1 Hertz
limit are laboratory grade instruments and the instruments with frequency limit of 6 Hertz are
outdated. Tr.4 at 40. As an alternative to making the suggested changes, IAAP recommends that
the Board amend the noise regulations to defer to IDNR’s enforcement of Illinois’ aggregate
industry in accordance with Section 6.5 of the Surface Mined-Land Conservation and
Reclamation Act. PC 10.
 
IDNR submitted comments supporting IAAP’s position regarding the regulation of
blasting operations. PC 13. IDNR states that it regulates blasting operations at all surface
aggregate and coal mines in the State. IDNR employs conservative limits of 1 inch per second
ground vibration and 133 decibels maximum air over pressure.
Id
. IDNR states that regulatory
compliance at all of the State’s 172 active aggregate and coal blasting sites is determined by
routine inspection and monitoring by highly trained field staff. In light of this, IDNR requests
that the Board take into consideration IAAP’s recommendations and avoid any duplicity between
the State agency regulations. In addition, IDNR recommends that air over pressure limit be
established at the commonly accepted industry standard of 133 decibels at 2.0 Hertz.
 
Discussion
 
The Board appreciates the testimony and comments presented by IAAP and IDNR
regarding the blasting noise standards. While the Board recognizes that the State’s aggregate
mining industry is regulated by IDNR pursuant to the Surface Mined-Land Conservation and
Reclamation Act (215 ILCS 715/6.5 (2002)), any noise emissions from the activities at the
aggregate production sites are also subject to the Board’s noise regulations under Section 24 of
the Act (415 ILCS 5/24 (2002)). Given the broad applicability of the noise prohibition set forth
at Section 24 of the Act (415 ILCS 5/24 (2002)), any exemption from the Board’s noise

 
7
regulations would require a statutory amendment. The statute specifically excludes “any
organized amateur or professional sporting activity” with certain exceptions from the nuisance
noise provisions of Section 24 of the Act (415 ILCS 5/24 (2002)). 415 ILCS 5/25 (2002).
However, the statute is silent concerning the aggregate mining industry. Therefore absent a
statutory exclusion, the provisions of Section 24 of the Act (415 ILCS 5/24 (2002)) apply.
 
Based on the plain language of the Act, the Board declines to defer the regulation of
noise emissions from the aggregate industry to IDNR. However, the Board will amend Section
901.109 as suggested by IAAP and IDNR to ensure that the aggregate industry is subjected to a
consistent statewide regulatory standard.
 
The Board changes the equivalent maximum sound pressure level limit for a sound
measuring instrument with lower frequency limit of 2.0 Hertz at Section 901.109(b) from: 132
decibels to 133 decibels for receiving Class A land; and 137 decibels to 133 decibels for
receiving Class B land. The limit of 133 decibels reflects the IDNR standard set forth at 35 Ill.
Adm. Code. In addition, the Board eliminates the equivalent maximum sound pressure level
limits for receiving Class A and Class B land for instruments with lower frequency limits of 0.1
Hertz and 6.0 Hertz. As noted by Mr. Tittman, the 0.1 Hertz instruments are laboratory grade
instruments, which are not used in the field and the 6.0 Hertz devices are no longer
manufactured.
 
Site-Specific Noise Regulations Concerning Forging Industry
 
The Board has adopted a number of site-specific noise regulations pertaining to forging
industry under Part 901. On March 4, 2004, the Board determined that “administrative economy
supports including the site-specific changes” in this rulemaking proposal. In response to that
order, the Board received comments from four companies that are subject to a site-specific rules.
Moline Forge commented on the proposal noting that the site-specific rule is “still required and
critical for Moline Forge to operate” and does not seek a change to the rule. PC 8 at 1. Three of
the companies that are subject to the site-specific rules have filed comments seeking changes to
those rules. These companies include Scot Forge, Vaughan and Bushnell Manufacturing
Company, and Intermet Decatur Foundry. The following discussion explains the site-specific
changes suggested by the three companies.
 
Scot Forge
 
Scot Forge seeks a revision of the site-specific rule at Section 901.118 that applies to one
of Scot Forge’s divisions, Atlas Forge located in Cicero, Illinois. Scot Forge states that it
purchased another drop hammer forging company located in Franklin Park, Illinois in 1992 and
consolidated the Cicero Plant operations described in Section 901.118 with the Franklin Park
facility. PC 3. Scot Forge notes that the Cicero Plant was shut down and the property was sold
upon completion of the consolidation. Scot Forge now requests that the Board amend the site-
specific rule at Section 901.118 to: (1) reflect the change in location of Scot Forge’s operation
from Cicero to Franklin Park; (2) increase the number of hammers allowed to operate at any
given time from six to seven; and (3) change the operating hours from 6 a.m. to 6 p.m. to 6 a.m.
to 11 p.m.

 
8
 
Mr. John McGillivray, Manager of Safety and Environmental Affairs, testified on behalf
of Scot Forge regarding the consolidated operation and the requested relief. Mr. McGillivray
stated that the Franklin Park facility is bordered on the east by Wisconsin Central Railroad line,
on the west by Nelson Steel, and on the south across the street by a bakery. Tr.3 at 9-10, 14.
Further, he noted that residential homes are located to the east of the facility and also on the side
streets behind the businesses along Belmont avenue (north). Tr.3 at 20. Mr. McGillivray noted
that the nearest residence is located west of Nelson Steel at a distance of approximately 100
yards from Scot Forge’s facility. Tr.3 at 11, 14.
   
Regarding the forging operation, Mr. McGillivray stated that while the facility purchased
from Hellstrom Corporation had eight steam drop hammers, currently Scot Forge operates only
six hammers at the facility. Tr.3 at 8. He noted that the hammers are 30 to 50 years old.
Although the initial request for relief was based on six hammers operating at any one time, Mr.
McGillivray requested that the Board grant relief for the operation of seven hammers at any
given time.
Id
. He noted that the addition of the seventh hammer would provide operational
flexibility to accommodate growth in the business.
Id.
Scot Forge’s annual sales are expected to
increase from $145 million to $ 154 million in 2004. Tr.2 at 6. Scot Forge employs
approximately 60 people at the Franklin Park facility. Tr.3 at 15.
 
With regard to operating hours, Mr. McGillivray explained that while currently the
hammers are operated only during the first shift, Scot Forge might run them during second shift
if business continues to grow. Tr.3 at 15. At present he noted “second shift personnel only run
the machine side and heat treat operations, and then third shift is a . . . one maintenance person
and one heat treat operator. So those, generally speaking, are noiseless operations.” Tr.3 at 16.
Mr. McGillivray stated that the majority of noise from the operations comes between 6 a.m. and
approximately 3:30 to 4:00 p.m.
Id
.
 
Mr. McGillivray also provided testimony on the ambient noise and the noise levels
emanating from the forging operations. Mr. McGillivray maintained that noise levels in the area
are exceptionally high because of the train traffic on Wisconsin Central Rail Road, which is one
of the largest and busiest railroads in the area. Tr.3 at 9. Regarding the noise from the facility,
he noted that while the noise levels inside the building range from 110 to 114 dB, the noise
levels outside at the facility perimeter is typically down 92 to 93 dB. Tr.3 at 9-10. Mr.
McGillivray stated that he measured the noise levels by using a noise dosimeter. Tr.3 at 13. He
also clarified that the facility does not utilize any specific acoustic baffling material. Tr.3 at 20-
21. Mr. McGillivray stated Scot Forge works with the Franklin Park community to resolve any
issues that may come up, and during his six-year tenure, he has not received a single noise
complaint. Tr.3 at 10.
 
Scot Forge proposes the following changes to Section 901.118:
 
Section 901.118 Atlas Forgings Division of Scot Forge Company – Franklin Park
Division Operational Level
 

 
9
Atlas Forge Division of Scot Forge and future owners of the forging facility
located at 9394 W. Belmont Avenue, Franklin Park 1501 South 55th Court,
Cicero, Illinois, shall comply with the following site-specific operational level:
 
a) Operate no more than seven three forging hammers at any one time; and
 
b) Operate its forging hammers only between the hours of 6:00 a.m. and
116:00 p.m. Monday through Saturday.
 
Discussion.
The Board adopted the site-specific rule for Scot Forge’s Cicero forging
operation in Atlas Forging Division of Scot Forge Petition for Site-Specific Operational Level
Pursuant to Chapter 8: Noise Pollution, R83-34 (Dec. 20, 1984) (R83-34) pursuant to Section
901.105(d), which allows an existing impact forging operation (pre-1982) to seek site-specific
relief if the facility is unable to comply with numeric standards for forging operations set forth at
Section 901.105. Section 901.105(d) prescribes detailed informational requirements for filing
site-specific petitions, including a filing deadline of December 31, 1983. Although, the current
request from Scot Forge is not filed pursuant to Section 901.105(d), the Board considers the
informational requirements as a guide in making its determination on Scot Forge’s request.
These requirements include the following:
 
A) The location of the petitioner, a description of the surrounding community,
and a map locating the petitioner within the community;
 
B) A description of the petitioner's operations, the number and size of the
petitioner's forging hammers, the current hours of hammer operation, the
approximate number of forgings manufactured during each of the three
prior calendar years and the approximate number of hammer blows used to
manufacture the forgings.
 
C) A description of any existing sound abatement measure.
 
D) The sound levels in excess of those permitted by subparagraph (c) emitted
by the petitioner into the community, in 5-decibel increments measured in
Leq, shown on the map of the community.
 
E) The number of residences exposed to sound levels in excess of those
permitted by subparagraph (c);
 
F) A description of other significant sources of noise (mobile and stationary)
and their location shown on the map of the community. 35 Ill. Adm. Code
901.105(d).
 
Scot Forge’s Franklin Park facility is located at 9394 W. Belmont Avenue, which is a
mixed land use location with commercial, industrial and residential properties. While Scot Forge
did not provide a map locating the facility and surrounding area, the record indicates that a major
railroad line on one side and a steel company on the other border the facility. The nearest

 
10
residence is located 100 yards from the facility. Although Scot Forge did not provide a detailed
noise survey based on Leq measurements, Mr. McGillivray testified that A-weighted noise levels
near the perimeter of the facility range from 92 to 93 decibels and the ambient noise is
exceptionally high mainly because of the train traffic. Further, Scot Forge has not received any
noise complaints from its neighbors.
 
Scot Forge was asked to inform the Board if any of the factors considered by the Board in
granting site-specific relief to its Cicero plant had changed over the years. So far, Scot Forge has
not submitted any new information regarding economic reasonableness and technical feasibility
of complying with the rule of general applicability.
 
At this time, the Board proposes to grant the requested site-specific relief based upon the
information in the record, and the Board’s prior site-specific rulemakings concerning existing
forging industry. Particularly, the Board relies on its prior decisions regarding economic
reasonableness and technical feasibility. The records in a number of site-specific regulations
concerning forging industry, including Scot Forge’s Cicero operation clearly, indicate that while
compliance is technically feasible, the extremely high cost of compliance makes it economically
unreasonable.
See
R83-34.
 
Given that Scot Forge has been operating the Franklin Park facility over 10 years without
any complaints, the Board believes that allowing the operation of seven hammers would not
result in significant noise impact on the area residents. In this regard, the Board notes that prior
rulemaking records indicate that noise from forging hammers does not endanger the hearing of
area residents. Although Scot Forge requests that the hammers be allowed to operate from 6
a.m. to 11 p.m., the Board proposes to limit the operation of the hammers from 6 a.m. to 6 p.m.
since the record indicates that noise from the operations comes between 6.00 a.m. and
approximately 3:30 to 4 p.m. The Board invites Scot Forge to provide additional information for
the record during the first-notice period, if Scot Forge believes that the change in the hours of
operation should be until 11 p.m.
 
Vaughan and Bushnell Manufacturing Company
 
Vaughan and Bushnell filed comments seeking revision of the site-specific rule at Section
901.121, which applies to its facility located at the intersection of Davis and Main Streets,
Bushnell, Illinois. Vaughan and Bushnell requests that the Board revise Section 901.121 to
allow the facility to operate 11 hammers at any one time instead of 10 hammers allowed under
the current rule. PC 4. Vaughan and Bushnell also seek a correction in the hours of operation
from “6 a.m. to 1:30 p.m.” to “6 a.m. to 1:30 a.m.” in the site-specific rule.
 
Discussion.
In reviewing the Board’s opinion and order in Vaughan and Bushnell’s site-
specific rule (R83-32, May 2, 1985), a misprint was found. The misprint inadvertently changed
the allowed hours of operation from “6 a.m. to 1:30 a.m.” to “6 a.m. to 1:30 p.m.” in the rule
text. The Board will therefore make that change. However, the Board notes that other than
requesting that the number of hammers be changed from ten to eleven at Section 901.121(b),
Vaughan and Bushnell’s comments do not provide any information regarding the use of an
additional hammer or the impact on noise emissions. In light of this, the Board declines to make

 
11
the requested change, as the record does not support the changes. The Board invites Vaughan
and Bushnell to provide additional information for the record during the first-notice period, if
Vaughan and Bushnell believes that the additional hammer is necessary.
 
Intermet Decatur Foundry
 
Intermet Foundry, which is also known as Wagner Casting, filed comments requesting
that the Board repeal the site-specific rule applicable to Wagner Casting at Section 901.113.
Intermet Foundry’s comments note that forging operation at the facility ceased prior to 1984 and
all equipment associated with the forging operations has since been dismantled and either sold or
discarded. PC 7 and 9. Further, Intermet Foundry states that it has no intention of re-
establishing forging operation at the Decatur facility.
 
Discussion.
The Board appreciates Intermet Foundry’s comments and proposes to repeal
the site-specific rule applicable to Wagner castings at Section 901.113.
 
Other Issues
 
Mr. Chinn’s comments on behalf of the AGO presented two issues for the Board. First,
Mr. Chinn requested that the Board reconsider its decision not to adopt a state-wide rule to limit
the hours of operation for lawn care equipment and set sound limits for such equipment. PC 11.
Mr. Chinn submitted an ordinance from the Village of Morton Grove’s municipal code that
regulates the noise levels, and hours of operation of lawn equipment to support the AGO’s
position. Second, Mr. Chinn also suggested that the Board adopt a five-minute measurement
period rather than the current one-hour measurement period. PC 1 at 2.
 
Discussion
 
The Board appreciates Mr. Chinn’s comments; however, the Board declines to limit the
hours of operation for lawn care equipment since such a limitation is beyond the scope of this
rulemaking. As to Mr. Chinn’s second suggestion, the Board addressed that issue in a previous
rulemaking docket.
See
Noise Rule Update: Amendments to 35 Ill. Adm. Code 900 and 903,
R03-8 (June 5, 2003). In that rulemaking the Board adopted a ten-minute interval measurement
period and replaced the Board’s prior rule requiring a one-hour averaging for sound pressure
measurements.
 
PROPOSAL OVERVIEW
 
The Board will explain each section of the rule in the following discussion.
 
35 Ill. Adm. Code 910: Measurement Procedures for the
Enforcement of 35 Ill. Adm. Code 900 and 901
 
 
The proposed new Part 910 sets forth the measurement procedures for enforcing the
Board’s noise standards in Parts 900 and 901. These procedures are essentially based upon the
Agency’s noise measurement protocols at 35 Ill. Adm. Code 951. The Board has made a number

 
12
of substantive changes to the Agency’s measurement protocols to reflect the recommendations of
the IDNR’s noise reports. A brief description of the proposed procedures is provided below.
 
Section 910.100 General
 
This Section sets forth the scope of the proposed noise measurement procedures and
techniques. The Board has deleted references to “Agency personnel,” since the measurement
procedures are applicable to any person conducting noise measurements to demonstrate
compliance with Parts 900 and 901.
 
Section 910.101 Personnel Qualification
 
The Board decided not to incorporate the Agency’s personnel qualification requirements
in the instant proposal since they are specific to Agency personnel, and also because the
requirements are not based on any State approved licensing or certification. (
See infra
@)
 
Section 910.102 Instrumentation
  
 
This section sets forth the requirements for sound measuring equipment, sound indicating
devices such as magnetic tape recorder or graphic level recorder, and weather measuring
instruments. These requirements are the same as those in Part 951, except for the updated
references to the American National Standards Institute (ANSI), and the International
Electrotechnical Commission (IEC) standards.
See
changes at Section 910.102(a).
 
Section 910.103 Definitions
 
The Board has moved all pertinent definitions found in the Agency’s regulations to 35 Ill.
Adm. Code 900.103, which contains the definitions applicable to the Board’s noise regulations.
 
Section 910.104 Measurement Techniques for 35 Ill. Adm. Code 900
 
This section clarifies that while sound pressure level measurements are not required to
establish a violation of the Board’s nuisance noise standard at 35 Ill. Adm. Code 900.102, such
measurements may be used as corroborating evidence. In this regard, the proposal requires a
person conducting sound measurements to comply with the instructions of the sound
measurement equipment manufacturer. Further, Section 910.104 sets forth that the measurement
techniques proposed at Section 910.105 may be used as guidance. While the proposed approach
deviates from the detailed sound measurement requirements specified in Part 951, the Board
believes that the proposed approach is consistent with the Board’s precedence and case law
concerning nuisance noise complaints. (
See infra
@)
 
Section 910.105 Measurement Techniques for 35 Ill. Adm. Code 901
 
The measurement techniques for obtaining sound pressure levels to demonstrate
compliance with Part 901 standards are essentially the same as the Agency’s regulations, except
for the deletion of measurement procedures for steady sound, fluctuating sound, intermittent

 
13
sound, impulsive sound, and quasi steady sound set forth at Sections 910.105 (d)(3) through
(d)(7), respectively. The Board notes that these measurement procedures are addressed by the
measurement techniques for highly-impulsive sound set forth at Section 910.107.
 
Section 910.106 Protocols for Determination of Sound Levels
 
This section sets forth a systematic set of procedures for determination of equivalent
sound level (Leq) using as an example the determination of a 1-hour Leq corrected for background
ambient sound. The proposed protocols are based on the recommendations of the Department’s
noise study entitled “ Proposed Revisions to Property Line Noise Source: Measurement
Procedures.” These protocols prescribe detailed data collection requirements, and equations for
averaging sound data on an energy basis. In addition, Section 910.106 prescribes procedures
correcting the raw equivalent sound level for background ambient sound. The proposal also
prescribes detailed procedures for measuring background ambient sound that include both direct
measurement methods and the use of Tables of long-term background ambient.
 
Section 910.107 Measurement Techniques for Highly-Impulsive Sound under 35 Ill.
Adm. Code 901.104
  
Two equally valid methods are proposed for measuring highly-impulsive sound. The
first method, termed the “General Method” at Section 901.107(b), provides for A-weighted Leq
measurement using the procedures set forth in Sections 910.105 and 910.106. The second
method, which is referred to as the “Controlled Test Method” at Section 910.107(c), involves the
determination of total sound exposure per hour. Again, the Board notes that the proposed
protocols are based on the Department’s noise study.
 
35 Ill. Adm. Code 901: Sound Emission Standards and Limitations for
Property Line-Noise-Sources
 
The proposed changes to Part 901 replace the existing Standard Land Use Coding
Manual (SLUCM) based land classification, and revise the impulsive sound standards. A brief
description of the proposed changes is provided below.
 
Section 901.101 Classification of Land According to Use
 
The changes proposed to this section update the existing land use classification, which is
based on SLUCM codes, with the Land-Based Classification Standards (LBCS) codes. The
Board notes that the LBCS, which replaced the 1965 SLUCM, provides a consistent model for
classifying land uses based on a multi-dimensional land use classification model. While the
LBCS provides for classification of land use based on activity, function, structure type, site
development character, and ownership, the Board is proposing to update the SLUCM codes with
the LBCS function codes. In this regard, the Board believes that the LBCS functional categories
are very similar to the SLUCM categories listed in the existing regulations at Part 901, Appendix
B.
 

 
14
Consistent with the changes proposed to Section 901.101, the instant proposal also
replaces the SLUCM Codes Table in Part 901, Appendix B with the LBCS function codes. For
more detailed information concerning the LBCS, the Board directs interested persons to review
the LBCS executive summary or visit the LBCS web page (www.planning.org/LBCS ).
 
Section 901.104 Highly-Impulsive Sound
 
The proposed changes to Section 901.104 clarify that the impulsive sound standards are
based on 1-hour A-weighted equivalent sound levels, and revise the numeric standards. The
revisions to the numeric limits for highly-impulsive sound are based on the recommendations of
the Department’s Impulse Noise Study. These revisions are intended to bring highly impulsive
noise standards into conformity with the standards set forth in Sections 901.102 and 901.103 in
terms of the effective community response. A more detailed discussion of the proposed
revisions may be found in proposal.
 
CONCLUSION
 
Based on the record developed to date in this matter, the Board finds that adoption of the
following rulemaking for the purposes of first notice is warranted. As four hearings have been
held on the proposal, the Board does not presently plan to hold an additional hearing unless one
is requested during the first-notice period under Section 5-40 of the Administrative Procedure
Act.

1) An existing impact forging operation which does not comply with
subparagraph (c) may seek a permanent site specific allowable operational
level from the Board. A permanent site specific level is that level of
operation allowed petitioner after review and approval by the Board and
after implementation of abatement abated measures, if any, approved by
the Board.
 
2) Any existing impact forging operation seeking a permanent site specific
operational level must submit as its petition the following:
 
A) The location of the petitioner, a description of the surrounding
community, and a map locating the petitioner within the
community;
 
B) A description of the petitioner's operations, the number and size of
the petitioner's forging hammers, the current hours of hammer
operation, the approximate number of forgings manufactured
during each of the three prior calendar years and the approximate
number of hammer blows used to manufacture the forgings.
 
C) A description of any existing sound abatement measure.
 
D) The sound levels in excess of those permitted by subparagraph (c)
emitted by the petitioner into the community, in 5 decibel
increments measured in Leq Leq, shown on the map of the
community.
 
E) The number of residences exposed to sound levels in excess of
those permitted by subparagraph (c);
 
F) A description of other significant sources of noise (mobile and
stationary) and their location shown on the map of the community;
 
G) A description of the proposed operational level and proposed
physical abatement measures, if any, a schedule for their
implementation and their costs;
 
H) The predicted improvement in community sound levels as a result
of implementation of the proposed abatement measures; and
 
I) A description of the economic and technical considerations which
justify the permanent site specific allowable operational level
sought by petitioner.
 

 
21
3)
An existing impact forging operation seeking a permanent site specific
operational level shall prepare and file its petition with the Board and
Agency as applicable no later than December 1, 1983.
 
4)
The Agency shall prepare a written evaluation regarding each petition
seeking a permanent site specific operational level and shall file said
evaluation within ninety (90) days following receipt of the petition with
both the Board and the petitioner.
 
e) Land Use Classifications Preserved
 
The land use classifications in effect within a one-mile radius of an existing
impact forging operation on September 1, 1982 remains shall remain the
applicable land use classification for enforcement of these rules against an
existing forging operation and any future modification thereof, regardless of
actual subsequent changes in land use unless such actual changes would impose
less restrictive limitations on the impact forging operations.
 
f) Site-Specific Operational Levels. Each individual existing forging operation
identified in Sections 901.110, 901.111 and 901.112 must comply with the site-
specific operational level defined, or is otherwise subject to Section 901.105(c).

Section 901.106 Prominent Discrete Tones
 
a) No person shall cause or allow the emission of any prominent discrete tone from
any property-line-noise-source located on any Class A, B or C land to any
receiving Class A, B or C land, provided, however, that no measurement of one-
third octave band sound pressure levels shall be made less than 25 feet from such
property-line source.

Section 910.103 Definitions
 
The definitions contained in 35 Ill. Adm. Code 900.101 apply to this Part.
 
  
Section 910.104 Measurement Techniques for 35 Ill. Adm. Code 900
 
Sound pressure level measurements are not required to establish a violation of 35 Ill. Adm. Code
900.102 (nuisance noise). However, sound pressure level measurements may be introduced as
corroborating evidence when alleging a violation of 35 Ill. Adm. Code 900.102. If sound
pressure level measurements are collected, manufacturer’s instructions must be followed for the
equipment used and 35 Ill. Adm. Code 910.105 may be used as guidance in gathering data.
 
Section 910.105 Measurement Techniques for 35 Ill. Adm. Code 901
 
 
Sound pressure level measurements must be obtained in accordance with the following
measurement techniques to determine whether a noise source is in compliance with 35 Ill. Adm.
Code 901:
 
a) Site Selection
 
1) Measurements may be taken at one or more microphone positions within
the appropriate receiving land. Measurement instruments must be set up
outdoors within the boundaries of the receiving land for the purpose of
determining whether a noise source is in compliance with 35 Ill. Adm.
Code 901.
 
2) Measurement instruments must be set up not less than 25 feet (7.6 meters
(m)) from the property-line-noise-source. The 25-foot (7.6 m) setback
requirement is from the noise source and not the property line unless the
noise source is contiguous to the property line.
 
3) Other measurement locations may be used for investigatory purposes such
as, but not limited to, the following:
 
A) Determining the extent of noise pollution caused by the source of
sound;
 
B) Determining the ambient; and

 
77
 
C) Analyzing those acoustical parameters that describe the sound
source.
 
4) For measurements of sound sources with no audible discrete tones,
microphones should not be set up less than 25 feet (7.6 m) from any
reflective surface which may affect data. If measurements must be taken
within 25 feet (7.6 m), the effect, if any, of the reflective surface on the
measured data must be determined.
 
5) For measurements of sound sources with audible discrete tones,
microphones must not be set up less than 50 feet (15.2 m) from any
reflective surface which may affect data. If measurements must be taken
within 50 feet (15.2 m), the effect, if any, of the reflective surface on the
measured data must be determined.
 
6) Objects with small dimensions (trees, posts, bushes, etc.) must not be
within 5 feet (1.5 m) of the microphone position. If measurements must
be taken within 5 feet (1.5 m) of such objects, the effect, if any, on the
measured data must be determined.
 
b) Instrumentation Set Up
 
1) A tripod must be set at the chosen site. The tripod must be extended to a
height between 3 feet 8 inches (1.12 m) and 4 feet 10 inches (1.47 m)
above ground.
 
2) A microphone must be attached to the appropriate end of a 5-foot (1.5 m)
or longer cable and must be affixed to the top of the tripod. The other end
of the cable must be connected to the measuring instrument
 
3) The angle of incidence of the microphone must be adjusted to yield the
flattest frequency response in accordance with the manufacture’s
specifications.
 
4) The measuring instrument must be separated from the microphone so as to
minimize any influence on the measurements. The cable movement must
be minimized during the measurement period.
 
c) Measurement Site Operation and Instrument Calibration
 
1) Before taking sound pressure level measurements, measure and record
(near the measurement site):
 
A) Wind speed and direction;
 

 
78
B) Ambient temperature;
 
C) Relative humidity; and
 
D) Barometric pressure.
 
2) Turn the measuring instrument on and allow the instrument to stabilize.
Monitor and record the battery condition of the calibrator and all
measuring instruments.
 
3) Turn the calibrator on at its appropriate frequency. Allow the calibrator to
stabilize and calibrate the measuring system according to the
manufacturer's specifications. After the measuring system has been
calibrated, remove the calibrator and attach a windscreen to the
microphone.
 
4) Adjust the microphone to the angle of incidence that will yield the
frequency response in accordance with the manufacturer's specifications.
 
5) Measure the sound pressure level data within the limitations of subsection
(d) and according to the manufacturer's recommended procedures. Other
sound pressure levels may be used for investigatory purposes such as, but
not limited to, the following:
 
A) Determining the extent of noise pollution caused by the source of
sound;
 
B) Determining the ambient; and
 
C) Analyzing those acoustical parameters that describe the sound
source.
 
6) While sound measurements are being taken, the operator must be
separated from the microphone so as to minimize any influence on the
measurements.
 
7) While measurements are being taken, visual and aural surveillance of
extraneous sound sources and varying wind conditions must be made to
insure that the conditions of measurement are accurately known. Record
any variations in these parameters that may affect data. The number and
basis for affected data block must be recorded. When using a tape
recorder, voice commentary concerning conditions will be recorded on the
cue track.
 

 
79
8) To minimize wind effects on the microphone, sound measurements must
not be taken when the wind velocity is greater than 12 miles per hour
(5.4 m/second) at the microphone position.
 
9) For the purposes of data correction, the ambient sound at the measurement
site must be determined by means of measurement or analysis.
 
10) After taking sound pressure level measurements, remove the windscreen
and attach the calibrator to the microphone. Turn the calibrator on at its
appropriate frequency. After allowing the calibrator to stabilize, monitor
and record the measuring system response. When the measuring system
response varies by more than + 0.5 dB from the most recent field
calibration, the sound pressure level measurements obtained since such
most recent field calibration cannot be used for enforcement purposes.
 
11) Before removing the calibrator from the microphone, turn the calibrator
off. If the ambient sound has not been determined by means of
measurement, determine the noise floor of the measuring system. If the
noise floor is within 10 dB of the measured sound pressure level data, such
noise floor measurements must be recorded.
 
12) At the end of the sound survey, monitor and record the battery condition
of the calibrator and all measuring instruments. Near the measurement
site, measure and record:
 
A) Windspeed and direction;
 
B) Ambient temperature;
 
C) Relative humidity; and
 
D) Barometric pressure.
 
13) Record the physical and topographical description of the ground surface
within the vicinity of the measurement site, survey site location, a
description of the sound source, a diagram of the area, the location of
reflective surfaces near the microphone, and the approximate location of
the noise source relative to the microphone position.
 
14) A magnetic tape recorder may be used to preserve the raw data.
Calibration signals must be recorded at the beginning and end of each tape
as well as at intermediate times such as when relocating to a new
measurement site. Voice commentary concerning local conditions and
affected data blocks must be recorded on the cue track. The original tape
recording must be preserved for subsequent evaluation. Laboratory
analyses may be performed on magnetic tape recorded field data. A

 
80
description of the laboratory instrumentation and procedures must be
recorded. Analyses used in the laboratory must be correlated to field
measurement techniques.
 
d) Limiting Procedures for Specific Types of Data Acquisition
 
1) For measurements of non-impulsive sound with audible discrete tones,
one-third octave band sound pressure levels must be obtained in
determining whether a noise source is in compliance with 35 Ill. Adm.
Code 901.106.
 
2) For measurements of non-impulsive sound with no audible discrete tones,
octave band sound pressure levels must be obtained in determining
whether a noise source is in compliance with 35 Ill. Adm. Code 901.102
and 901.103.
 
 
e) Correction Factors
 
If necessary, correction factors rounded to the nearest 1/2 decibel must be applied
to sound pressure level measurements. The correction factors applicable to the
measurement system may include, but are not limited to, corrections for
windscreen interference and the sound pressure level difference between
consecutive field calibrations. Such calibration correction factors must only be
used to make negative corrections (subtraction from the field data). In no case
must such calibration correction factors be added to the measured sound pressure
levels so as to raise the sound pressure level field data. The correction factors
applicable to the measurement site may include, but are not limited to, corrections
for reflective surfaces and ambient sound.
 
Section 910.106 Protocols for Determination of Sound Levels
 
a) The raw data collection procedures for the determination of equivalent continuous
sound pressure level (Leq) are described in this Section using as an example the
determination of a 1-hour Leq corrected for ambient. The following procedures
must be used:
 
1) Using small blocks:
 
A) The 1-hour interval is divided into many small blocks of time such
that corruption of the data from short-term background transient
sound and loss of data can be limited to the corrupted or bad
blocks. The block duration in seconds must remain fixed for any
measurement hour. The duration must be neither less than 10
seconds nor greater than 100 seconds. For example, if the block
duration is chosen to be 60 seconds (1 minute), then the data
collection proceeds for 60, 1-minute periods of measurement.

 
81
 
B) The collected data for each block represents a block duration Leq
(or sound exposure level (SEL)) in octave bands (or 1/3-octave
bands if prominent discrete tones may be present).
 
C) Data for any block corrupted by one or more short-term
background transient sounds must be deleted.
 
D) After deleting corrupted data blocks, there will be a fixed number
of “good” data blocks remaining. This number is designated as
NPLNS, where PLNS stands for Property-Line-Noise-Source.
These remaining “good” blocks must be numbered consecutively.
The subscript i is used to denote the numbering of the blocks in
time order after corrupted data blocks have been deleted.
 
E) The data for the NPLNS remaining blocks are time averaged on an
energy basis by octave (or 1/3-octave band) using Equation 1
below. In this equation, two subscripts are used, i to designate
time and j to designate the specific frequency, either an octave
band or 1/3 octave band. The raw, 1-hour Leq in the

an hour.
 

 
82
2) Continuous Data Collection:
 
A) The measuring instrument must be adjusted to continuously
measure sound pressure and accumulate Leq for each block of time.
For convenience, the hour may be split into several smaller blocks
such as 10, 6-minute blocks or 4, 15-minute blocks, etc.
 
B) A switch on the measuring instrument must be available to inhibit
data collection whenever a short-term background transient sound
occurs. This switch shall be used to prevent short-term
background ambient sounds from corrupting the data.
 
C) Data collection must proceed for one hour. The energy average of
the several measured Leqij each weighted by the number of seconds
actually accumulated during the
i
th block results in the raw, 1-hour

3) Minimum data collection requirements:
 
A) Initial Measurement Duration.
The property-line-noise-source
measurements must proceed initially for one hour. Because of
correction for short-term background transient sounds, actual
reported data collection time T, in seconds, may be less than 3600
seconds (one hour).
 
i) If small blocks of data are used for data collection, then the
total measurement duration in seconds, TPLNS is given by
NPLNS T, where T is the length of each block in seconds and
NPLNS is the number of non-discarded blocks. If data
inhibition is used for data collection, then TPLNS is the
number of non-inhibited seconds during the measurement
hour. In either case, TPLNS must be no less than 900
seconds.
 

 
83
ii) If very few blocks were used for data collection, then the
duration of each block, T, may be too long and should be
reduced.
 
iii) For either data collection method, sounds considered to be
short-term transient may actually be part of the long-term
background ambient and should be so redefined.
 
B) Extended Measurement Duration. If TPLNS is less than 900 seconds
during the first hour of measurements, the raw data collection
procedures must be appropriately modified and new measurements
must proceed for an additional hour. If TPLNS after combining the
first and the second hour of measurements is also less than 900
seconds, then the raw data collection must continue using the data
inhibition method or method employed during the second hour
until TPLNS is greater than or equal to 900 seconds.
 
4) Correction for Long-Term Background Ambient Sound:
 
A) The raw 1-hour Leq must be corrected for long-term background
ambient sound. The subsection below describes methods to obtain
the long-term background ambient sound level in the jth frequency
band. The correction is dependent on the difference (in decibels)
between the raw, 1-hour, jth band property-line-noise-Source: Leqj
and corresponding jth band long-term background ambient sound
level. The correction to be applied is as follows:
 
i) If the difference between the raw 1-hour Leq and the
long-term background ambient sound is larger than
10 decibels, then the correction must be set to 0.
 
ii) If the difference between the raw 1-hour Leq and the
long-term background ambient sound difference is
less than 3 decibels, then the
j
th frequency-band
level, Leqj, must be set equal to 0.
 
iii) If the difference between the raw 1-hour Leq and the
long-term background ambient sound is between 3
and 10 decibels then the correction given in Table 1
below must be subtracted from the raw, 1-hour
property-line-noise-source Leqj

5 1.7
6 1.3
7 1.0
8 0.7
9 0.6
10 0.5
 
B) The long-term background ambient corrected level must be the
property-line-noise-source Leqj reported for the jth frequency band.
 
b) Obtaining the background ambient sound level:
 
1) The background ambient must be measured for the purposes of this
Section during a 10-minute interval.
 
2) Long-term background ambient measurement procedures are similar to
procedures to measure the property-line-noise-source itself. Eliminating
short-term background ambient transient sounds from the measurement of
average long-term background ambient sound proceeds in a manner
similar to the measurement of the property-line-noise-source emissions
themselves. The two methods for measurement are: to divide the 10-
minute measurement into short blocks of data, or inhibit data collection
when short-term background transient sounds occur. The same method
must be used for gathering both the property-line-noise source data and
the corresponding long-term background ambient data. The measurement
procedures for each method are given in subsections (b) (3), (b) (4) and
(b) (5) of this Section:
 
3) Using small blocks of data
 
A) The 10-minute measurement of long-term background ambient
must be divided into short measurement blocks. The duration of
these blocks must remain constant during the entire measurement,
both when measuring the long-term background ambient and when
measuring the property-line-noise-source. The duration of this
measurement block in seconds, T, must divide exactly (without
remainder) into 600 and must be neither greater than 100 seconds
nor less than 10 seconds.
 
B) All data for any measurement block corrupted by one or more
short-term ambient transient sounds must be discarded. The

 
85
number of remaining, non-discarded measurement blocks is
designated NBA, where
BA
stands for background ambient.
 
C) The Leq for each octave (or 1/3 – octave) band are time- averaged
on an energy basis over the NBA remaining measurement blocks to
obtain average long-term background ambient Leq per band.
Equation 1 (see subsection (a) (1) (E) of this Section) is used for
this calculation with NBA replacing NPLNS as the number of
elemental blocks to be summed. The total duration of the
measurement in seconds, TBA, is given by NBA multiplied by T.
 
4) Continuous Data Collection.
 
A) The measuring instrument must be adjusted according to
manufacturer’s instructions to continuously measure sound
pressure and accumulate (i.e record) Leq. A switch must be
available to inhibit data collection whenever a short-term
background transient sound occurs, (and on some instruments, a
button may be available to delete the most recent, previous data).
 
B) The switches or buttons must be used to prevent short-term
background ambient sounds from corrupting the data.
 
C) Data collection must proceed for 10 minutes. The result is the 10-
minute, long-term background ambient Leq in each band.
 
D) TBA is the number of non-inhibited measurement seconds during
the 10-minute measurement period.
 
5) The minimum duration, for either method, TBA must be no less than 150
seconds. If TBA is less than 150 seconds, then the measurement of the
long-term background ambient must continue beyond the original 10
minutes and until TBA for the total long-term background ambient
measurement is greater than or equal to 150 seconds.
 
6) Measurement Alternatives. The long-term background ambient-noise
should ideally be measured at the potential violation site just before
measurement of the property-line-noise-source emissions. However,
turning off the property-line-noise-source may not always be possible. The
following are a hierarchical order of five procedures for obtaining the long-
term background ambient noise. The first four procedures involves direct
measurement; the fifth procedure provides for use of tables of values
obtained from extensive measurements. These are not equivalent
procedures but are ordered from what is considered to be the most accurate
to what is considered to be the least accurate procedure.
 

 
86
A) Direct Measurement Procedure –1: With the property-line-noise-
source (PLNS) turned off, measure the long-term background
ambient noise within the hour before or within the hour after
measurement of the PLNS emissions at the location where the
PLNS measurements are being taken and with the measurement
equipment used for the PLNS measurements.
 
B) Direct Measurement Procedure-2: With the PLNS turned off,
measure the long-term background ambient during a similar time
period in terms of background ambient sound level, within one (1)
to twenty-four (24) hours before, or within one (1) to twenty-four
(24) hours after measurement of the PLNS emissions at the
location where the PLNS measurements are being taken and with
the measurement equipment used for the PLNS.
 
C) Direct Measurement Procedure- 3: With the PLNS turned off,
measure the long-term background ambient during some other
acoustically similar period within one (1) to thirty (30) days before,
or within one (1) to thirty (30) days after measurement of the PLNS
emissions. This alternate long-term background ambient
measurement time might be a Saturday night or anytime during a
Sunday or holiday. The measurements would be made at the
location where the PLNS measurements are being taken and with
the measurement equipment (or like equipment) used for the PLNS
measurement.
 
D) Direct Measurement Procedure-4: With the PLNS turned off,
measure the long-term background ambient noise during some
other acoustically similar period within thirty (30) to ninety (90)
days before, or within thirty (30) to ninety (90) days after
measurement of the PLNS emissions. These measurements would
be made at the location where the PLNS measurements are being
taken and with the measurement equipment (or like equipment)
used for the property-line-noise-source measurements.
 
E) Tables of Long-term Background Ambient Noise. Where none of
the alternatives can be used, use the applicable long-term
background ambient data taken from Tables A through D in
Appendix A of this Part. These tables are organized by
predominant land use and time of day (daytime or nighttime).
There are separate tables for octave and 1/3- octave bands. The
background environments presented in the table are based on
extensive measurements conducted in the Chicago area and are
divided into the five categories given below in accordance with
Bonvallet, G.L., “Levels and Spectra of Traffic, Industrial, and
Residential Area Noise,” Journal of the Acoustical Society of

 
87
America, 23 (4), pp 435-439, July, 1951; and Dwight E. Bishop
and Paul D. Schomer, Handbook of Acoustical Measurements and
Noise Control, Chapter 50, Community Noise Measurements, 3

Edition, Cyril M Harris, Editor , McGraw-Hill Book Co., New
York (1991).
 
i) Category 1: Noisy commercial and Industrial Areas. Very
heavy traffic conditions such as in busy downtown
commercial areas, at intersections of mass transportation
and other vehicles including the Chicago Transit Authority
trains, heavy motor trucks and other heavy traffic, and
street corners where motor many buses and heavy trucks
accelerate.
 
ii) Category 2: Moderate Commercial and Industrial Areas,
and Noisy Residential Areas. Heavy traffic areas with
conditions similar to subsection (b)(6)(E)(i) of this Section
but with somewhat less traffic, routes of relatively heavy or
fast automobile traffic but where heavy truck traffic is not
extremely dense, and motor bus routes.
 
iii) Category 3: Quiet Commercial and Industrial Areas, and
Moderate Residential Areas. Light traffic conditions where
no mass transportation vehicles and relatively few
automobiles and trucks pass, and where these vehicles
generally travel at low speeds. Residential areas and
commercial streets and intersections with little traffic
comprise this category.
 
iv) Category 4: Quiet Residential Areas. These areas are
similar to Category 3 in subsection (b)(6)(E)(iii) of this
Section but for this group the background is either distant
traffic or is unidentifiable.
 
v) Category 5: Very Quiet, Sparse Suburban or Rural Areas.
These areas are similar to Category 4 subsection
(b)(6)(E)(iv) of this Section but are usually in
unincorporated areas and for this group there are few if any
near neighbors.
 
Section 910.107 Measurement Techniques for Highly-Impulsive Sound Under 35 Ill. Adm.
Code 901.104.
 
a) Measurement of highly-impulsive sound under Rule 901.104 can be made in two
distinct and equally valid ways, namely the general method and the controlled test
method.

 
88
 
b) General Method: The general method is to measure the 1-hour, A–weighted Leq
(not the octave or 1/3 octave band levels) using essentially one of the two
procedures described in 35 Ill. Adm. Code 910.105 and 910.106.
 
1) The procedure using small blocks of time to collect data is as follows:
 
A) The hour must be divided into small blocks and the A-weighted Leq
must be measured for each of these small blocks of time. Leq must
be measured for the entire hour but data collection must be
inhibited whenever a short-term background transient sound
occurs.
 
B) The duration of each block must be held constant during the hour.
This duration in seconds must divide exactly into 900 and must be
neither greater than 100 seconds nor less than 10 seconds.
 
C) The data for any block corrupted by one or more short-term
background ambient sounds must be discarded.
 
2) The continuous data collection procedures is as follows:
 
A) Leq must be measured for the entire hour.
 
B) Data collection must be inhibited whenever a short-term
background transient sound occurs.
 
3) Correction for the long-term background ambient must be accomplished
using all of the other procedures and requirements enumerated in 35 Ill.
Adm. Code 910.105 and 910.106 must be complied with to determine an
A-weighted, 1-hour, background-ambient-corrected Leq for the highly
impulsive property-line-noise-Source: under study.
 
c) Controlled Test Method:
For this method, the following procedures must be used:
 
1) General Measurement Description
 
A) The sound exposure per impulse from each separate individual
impulsive Source: is measured.
 
B) The total sound exposure per hour from each Source: is the sound
exposure per event multiplied by the number of events per hour.
 
C) The grand total sound exposure (SE) per hours is the sum of the
sound exposures per hour from each of the separate individual
sources.

 
89
 
D) The reported SEL is obtained from the grand total sound exposure
(SE) per hour using the following:
 
SEL = 10 log (SE) + 94. [Eq. 7]
 
E) The equivalent level, Leq corresponding to a SEL measured or
predicted for one hour (3600 seconds) is given by:
 
Leq = SEL - 10 log (3600). [Eq. 8]
 
2) Determination of Sound Exposure per Event must be as follows:
 
A) The sound exposure per event from each, separate, individual
Source: must be determined by measuring the total A-weighted
sound exposure for about 10 repetitions of this source. This set of
about 10 measurements may be performed continuously over a
short period of time, or this set of measurements may be performed
over a discontinuous set of measurement periods. In either case,
the total measurement duration must be less than 100 seconds.
 
B) These separate, individual property-line-noise-Source: controlled
measurement must be free of any short-term ambient sounds. If
any short-term background transient sounds occur during these
measurements, then the measurement must be repeated until
measurement data, free of any corrupting short-term background
ambient sounds, are obtained.
 
C) The total measured A-weighted sound exposure for this group of
about 10 repetitions must be corrected for long-term background
ambient by subtracting the A-weighted long-term background
ambient sound exposure. The sound exposure value subtracted
must be the long-term A-weighted background ambient sound
exposure per second multiplied by the number of seconds used to
measure the several Source: repetitions.
 
D) The reported Source: A-weighted sound exposure per event must
be the total corrected sound exposure divided by the number of
Source: repetitions measured.
 
E) The background ambient must be measured for a short time, at
least 30 seconds as near in time to the Source: measurements as
possible, but within ½ hour. The total A-weighted long-term
background ambient sound exposure per second is the total
measured long-term background ambient sound exposure divided
by the number of seconds of background ambient measurement.

 
90
 
F) There must be no short-term background ambient sounds present
during the measurement of the long-term background ambient. If
any short-term background transient sounds occur during these
measurements, then the measurements must be repeated until long-
term background ambient measurement data free of any corrupting
short-term background ambient sound are obtained.
