Section 901.101
Classification of Land According to Use
a)
The land use classification system used for the purposes of applying numeric sound
standards for this Part is based on the Land-Based Classification Standards (LBCS) (Jeer,
Sanjay. 2001. Land-Based Classification Standards . Online,
H
http://www.planning.org/LBCS. American Planning Association: Chicago, Illinois).
The LBCS applicable to this Part is set forth in Appendix B.
b)
Class A land includes all land used as specified by LBCS Codes 1000 through 1340,
2410 through 2455, 5200 through 5230, 5500, 6100 through 6145, 6222, 6510 through
6530, 6568 through 6600.
c)
Class B land includes all land used as specified by LBCS Codes 2100 through 2336, 2500
through 2720, 3500 through 3600, 4220 through 4243, 5100 through 5160, 5300 through
5390, 5400, 6147, 6210 through 6221, 6300 through 6320, 6400 through 6430, 6560
through 6567, 6700 through 6830, 7100 through 7380.
d)
Class C land includes all land used as specified by LBCS Codes 3100 through 3440, 4120
through 4180, 4210 through 4212, 4300 through 4347, 7400 through 7450, 8000 through
8500, and 9100 through 9520.
e)
A parcel or tract of land used as specified by LBCS Code 9100, 9400, or 5500 when
adjacent to Class B or C land may be classified similarly by action of a municipal
government having zoning jurisdiction over such land. Notwithstanding any subsequent
changes in actual land use, land so classified retains such B or C classification until the
municipal government removes the classification adopted by it.

a)
For purposes of this Section, only the following are applicable:
1)
Daytime hours means any continuous 16-hour period between 6:00 a.m. and
11:00 p.m. local time; and
2)
Nighttime hours means those 8 hours between 10:00 p.m. and 7:00 a.m. which are
not part of the 16 continuous daytime hours.
3)
The reference time for L
eq
, as defined in 35 Ill. Adm. Code 900.101 is one hour.

4)
New Impacting Forging Operation is that property-line-noise-source comprised of
impact forging operation on which construction began after September 1, 1982.
5)
Existing Impact Forging Operation is that property-line-noise-source comprised
of impact forging operations which are in existence on September 1, 1982,
b)
Emission Limitations for New Impact Forging Operation.
No impact forging operation shall cause or allow the emission of impulsive sound to any
receiving Class A or B land which exceeds the allowable sound levels specified in the
following table when measured at any point within such receiving land, provided
however, that no measurement of sound levels shall be made less than 25 feet from such

Site Specific Allowable Operational Level for Existing Impact Forging Operation
1)
An existing impact forging operation which does not comply with subsection (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
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 subsection (c) emitted by
the petitioner into the community, in 5 decibel increments measured in
L
eq
, shown on the map of the community.
E)
The number of residences exposed to sound levels in excess of those
permitted by subsection (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.
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 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).
(Source: Amended at 30 Ill. Reg.5533, effective March 10, 2006)
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.
b)
This rule shall not apply to prominent discrete tones having a one-third octave band

such one-third octave band. In the application of this sub-section, the applicable numeric
standard for sound emitted from any existing property-line-noise-source to receiving
Class A land, for both daytime and nighttime operations, is found in Section 901.102(a).
