Section NR 421.04 - Pneumatic rubber tire manufacture
Universal Citation: WI Admin Code ยง NR 421.04
Current through August 26, 2024
(1) APPLICABILITY. This section applies, subject to the provisions of s. NR 425.03, to all pneumatic rubber tire manufacturing facilities involved in undertread cementing, tread end cementing, bead dipping, or green tire spraying operations.
(2) EXEMPTIONS.
(a) This section does not apply to the
production of specialty tires for antique or other vehicles when produced on an
irregular basis or with short production runs. This exemption applies only to
tires produced on equipment separate from normal production lines for passenger
type tires.
(b) The requirements of
sub. (3) do not apply provided the combined total VOC emissions from all
undertread cementing, tread end cementing, bead dipping and green tire spraying
operations are less than or equal to 57 grams per tire produced and the
emission rates are determined and certified by August 31, 1981.
(3) EMISSION CONTROL REQUIREMENTS. The owner or operator of a pneumatic rubber tire manufacturing facility shall:
(a) For all undertread cementing, tread end
cementing and bead dipping operations install and operate one of the following:
1. A carbon adsorption system which reduces
the VOC emissions from the capture system by at least 90% by weight.
2. An incineration or catalytic oxidation
system which oxidizes at least 90% of the nonmethane VOCs (measured as total
combustible carbon) which enter the incineration or oxidation unit, to
nonorganic compounds.
3. An
alternative VOC emission reduction system demonstrated to have at least 90%
reduction efficiency measured across the control system, as approved by the
department.
(b) For
green tire spraying operations, implement one of following control strategies:
1. Utilize water-based mold release compound
sprays with a volatile fraction containing, at a minimum, 90% water.
2. Install and operate a carbon adsorption
system which reduces the VOC emission from the capture system by at least 90%
by weight.
3. Install and operate
an incineration or catalytic oxidation system which oxidizes at least 90% of
the nonmethane VOCs (VOC measured as total combustible carbon) which enter the
incinerator or oxidation unit to nonorganic compounds.
4. Install and operate an alternate VOC
emission reduction system demonstrated to have at least a 90% reduction
efficiency, measured across the control system, as approved by the
department.
(c) For any
control device required by this section, install and operate a capture system,
as approved by the department, which is designed to provide maximum reasonable
capture and transfer of VOCs to the control device. Maximum reasonable capture
and transfer shall be in accord with guidance provided by:
1. Industrial Ventilation: A Manual of
Recommended Practice, 20th ed., incorporated by reference in s.
NR 484.11.
2.
Recommended Industrial Ventilation Guidelines, incorporated by reference in s.
