Current through Register Vol. 48, No. 38, September 20, 2024
a) The rule requirements of this Section
apply to a leather manufacturing facility at 2015 North Elston Avenue, Chicago,
Illinois. The VOM emission limits set forth in this Section shall only apply to
the following types of select grade of chrome tanned, bark/polymer retanned
specialty leathers:
1) Cementable Shoe
Leather is leather which is:
A) Hot stuffed
without the presence of water, fat liquored or wet stuffed by direct contact
with wax, grease, polymers and oils in liquefied form at elevated temperatures.
The content of wax, grease, polymers and oils embedded into the leather shall
be over 12 percent but less than 25 percent by weight, measured on a dry weight
basis. Applicable leathers shall be determined using the equation below:

Where:
P = W\L x 100
P = percent content of wax, grease, polymer, and oils
W = weight of wax, grease, polymers and oils in pounds added
to the leather
L = dry weight of the leather in pounds before addition of
wax, greases, polymers and oils;
B) Finished with coating materials which
adhere to the leather surface that feels oily; and
C) Used primarily for manufacture of shoes
and cannot meet the definition for specialty leather pursuant to 35 Ill. Adm.
Code Section 211.6170.
2) Dress or Performance Shoe Leather is
leather which is:
A) Finished with coating
materials containing water emulsified materials using water miscible solvent
materials to protect the leather and pigmented coating; and
B) Used primarily for manufacture of sewn
shoes where the leather must be capable of soaking with a fine, dressy finish
that cannot meet the lbs. per gallon VOM limitations set forth in Section
218.926 of this Subpart and cannot meet the definition for specialty leather
pursuant to 35 Ill. Adm. Code 211.6170.
3) The requirements of this Section do not
apply to the production of those specialty leathers that meet the definition of
specialty leathers pursuant to 35 Ill. Adm. Code 211.6170 or to the production
of leathers that can meet the control requirements of Section 218.926 of this
Subpart.
4) The 10-ton exemption
for stain pursuant to Section 218.926(b)(2)(i) of this Subpart does not apply
to leathers produced pursuant to the requirements of this Section.
b) The production of specialty
leather as defined in subsection (a) of this Section is subject to the
following limitations:
1) For both water
resistant and non-water resistant leathers, the leather will be designated as
water resistant or non-water resistant in the shipping room by using ASTM
D2099-00, as incorporated by reference in Section 218.112 of this
Part.
2) For non-water resistant
leathers, the total VOM emissions shall not exceed 14.0 lbs. VOM/1,000 square
feet of leather produced on a 12-month rolling average basis.
3) For water resistant leathers, the total
VOM emissions shall not exceed 24.0 lbs. VOM/1,000 square feet of leather
produced on a 12-month rolling average basis.
4) The total emissions of VOM from leathers
produced pursuant to the emission limits in this Section shall not exceed 20
tons per year.
c) The
owner or operator shall comply with its approved standard operating and
maintenance procedures (SOMP). The SOMP will contain the following elements:
1) A procedure to minimize the volatilization
of solvents during the measuring of coating proportions and/or mixing of
coatings.
2) A procedure to
minimize VOM fugitive losses from the coating and solvent storage rooms.
Procedures should include methods of securely sealing containers and methods to
clean up accidental spills.
3) A
procedure to minimize solvent usage or VOM losses during equipment cleanup and
during transport (including the transferring of coatings from the mixing areas
to the coating lines).
d) The owner or operator shall perform the
reporting and record keeping consistent with the requirements of Section
218.929 of this Subpart and Section 39.5 of the Act (415 ILCS
5/39.5) , and shall include at a minimum the
following:
1) The VOM content and gallons of
each coating and the total pounds of VOM of all coatings applied to each
category of leather, e.g., cementable non-water resistant, dress water
resistant, by batch during each month; and
2) The total area of each category of leather
produced during the month based on the number of items produced and the area of
such items, measured or established in accordance with procedures set forth in
a federally enforceable permit.
Notwithstanding the requirements of subsections (d)(1) and
(d)(2) of this Section, the owner or operator may comply with an equivalent
alternative plan for reporting and recordkeeping that has been approved by the
Agency and the USEPA in a federally enforceable permit or as a SIP
revision.
