Section 901.101  Classification of Land According to Use

a)         The land use classification system for applying the numeric sound standards of this Part is based on the Land-Based Classification Standards (LBCS) (Jeer, Sanjay; 2001; Land-Based Classification Standards; online at https://www.planning.org/lbcs;  American Planning Association:  Chicago, Illinois).  The LBCS applicable to this Part is 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, and 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, and 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 with zoning jurisdiction over that land.  Despite any subsequent changes in actual land use, land so classified retains the B or C classification until the municipal government removes the classification adopted by it.

Section 901.105  Impact Forging Operations

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.

2)         "Nighttime hours" means the 8 hours between 10:00 p.m. and 7:00 a.m. that 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 impact forging operation" means a  property-line noise source comprised of impact forging operation on which construction began after September 1, 1982.

5)         "Existing impact forging operation" means a property-line noise source comprised of impact forging operations that were in existence on September 1, 1982.

b)         Emission Limitations for New Impact Forging Operation

A new impact forging operation must not cause or allow the emission of impulsive sound to any receiving Class A or B land that exceeds the allowable sound levels specified in the following table, when measured at any point within the receiving land.  Sound pressure levels must be measured at least 25 feet from the new impact forging operation's property-line.

c)         Limitations for Existing Impact Forging Operation

Unless granted a permanent site-specific allowable operational level pursuant to subsection (d), an existing impact forging operation must not cause or allow the emission of highly impulsive sound to any receiving Class A or B land that exceeds the allowable sound levels specified in the following table, when measured at any point within the receiving land.  Sound pressure levels must be measured at least 25 feet from the existing impact forging operation's property line.

d)         Site Specific Allowable Operational Level for Existing Impact Forging Operation

1)         An existing impact forging operation that does not comply with subsection (c) may seek a permanent site-specific allowable operational level from the Board.  A permanent site-specific level is the level of operation allowed for a 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 with 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 that justify the permanent site specific allowable operational level sought by 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 remain the applicable land use classifications for enforcement of this Section against an existing forging operation and its future modification, regardless of actual subsequent changes in land use; unless those 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 through 901.122 must comply with either the site-specific operational level defined in those Sections or the allowable sound levels in Section 901.105(c).
