ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[WI72-01-7298a; FRL-5528-3]
Approval and Promulgation of State Implementation Plan;
Wisconsin; Site-Specific Revision For General Electric Medical Systems
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency approves a site-specific
volatile organic compound (VOC) reasonably available control technology
(RACT) state implementation plan (SIP) revision for the General
Electric Medical Systems (GEM) facility located at 4855 West Electric
Avenue in Milwaukee, Wisconsin. This SIP revision was submitted by the
Wisconsin Department of Natural Resources (WDNR) on March 15, 1996.
This approval makes federally enforceable the State's consent order
establishing an alternate control system for GEM's cold cleaning
operation.
In the proposed rules section of this Federal Register, the EPA is
proposing approval of, and soliciting comments on, this requested SIP
revision. If adverse comments are received on this action, the EPA will
withdraw this final rule and address the comments received in response
to this action in a final rule on the related proposed rule, which is
being published in the proposed rules section of this Federal Register.
A second public comment period will not be held. Parties interested in
commenting on this action should do so at this time. This approval
makes federally enforceable the State's rule that has been incorporated
by reference.
DATES: The ``direct final'' is effective on September 16, 1996, unless
EPA receives adverse or critical comments by August 16, 1996. If the
effective date is delayed, timely notice will be published in the
Federal Register.
ADDRESSES: Written comments should be sent to: Carlton T. Nash, Chief,
Regulation Development Section, Air Programs Branch (AR-18J), U.S.
Environmental Protection Agency, 77 West Jackson Boulevard, Chicago,
Illinois 60604.
Copies of the proposed SIP revision and EPA's analysis are
available for inspection at the U.S. Environmental Protection Agency,
Region 5, Air and Radiation Division, 77 West Jackson Boulevard,
Chicago, Illinois 60604. (Please telephone Kathleen D'Agostino at (312)

SUPPLEMENTARY INFORMATION:
I. Background
General Electric Medical Systems (GEM) owns a facility located at
4855 West Electric Avenue in Milwaukee, Wisconsin. The GEM facility
manufactures X-ray tubes and components for other medical systems, and
includes a cold cleaning operation which is part of an automated batch
chemical treatment process for X-ray tubes. The GEM facility is located
in the Milwaukee severe nonattainment area and is subject to rule NR
423 of the Wisconsin Administrative Code, which regulates VOC emissions
from solvent cleaning operations. This rule has been approved by the
United States Environmental Protection Agency (EPA) as meeting the RACT
requirements of the Clean Air Act (Act).
Specifically, under sections NR 423.03(3)(d), (i), and (j), GEM is
required to control organic compound emissions from the cold cleaning
operation through a freeboard ratio greater than or equal to 1.0,
through a water cover, or through an alternate control system
equivalent to a freeboard ratio of 1.0. Under section 423.03(9), any
alternate control method approved by the WDNR must be submitted to and
approved by EPA as a site-specific SIP revision. For the reasons
outlined below, GEM chose to install an alternate control system. The
WDNR has made the determination that the controls proposed by GEM are
more effective than those required by Rule 423 and has approved GEM's
proposal through Consent Order AM-96-200. On March 15, 1995, the
Wisconsin Department of Natural Resources (WDNR) submitted this Order
to EPA, along with associated materials, for incorporation into
Wisconsin's SIP.
II. Facility and Process Description
As noted above, GEM manufactures X-ray tubes and components for
other medical systems. This includes glass blowing, graphite target
manufacturing, cathode and anode machining and X-ray assembly. The X-
ray units are also tested and rebuilt at this facility.
The facility has a cold cleaning operation which is part of an
automated batch chemical treatment process for X-ray tubes. This
process consists of loading parts into a carrier that automatically
immerses them in various
[[Page 37217]]
chemicals, baths and water rinses, ending with immersion in the cold
cleaner bath which contains 95 percent ethanol and 5 percent methanol.
The equipment associated with the cold cleaning process was specially
made for this facility. The overhead conveyor was designed with a
limited vertical travel distance. With this limitation, the equipment
can not be modified to comply with a freeboard ratio greater than or
equal to 1.0 without significant expense. Consequently, GEM has
proposed an alternate control system.
GEM's proposed system includes an enclosed solvent storage tank,
control valves, pump and piping with an automated operating sequence.
The following is the proposed operation procedure for the equipment.
1. The cover opens.
2. The parts are lowered into an empty immersion tank.
3. The cover closes.
4. The solvent is pumped into the tank.
5. The parts are slowly agitated.
6. The solvent is drained from the tank.
7. The parts remain inside the tank until the excess solvent drips
off.
8. The cover opens.
9. The parts are removed.
10. The cover closes.
Additional design information for the proposed equipment is as
follows.
1. The cleaner will be fitted with a mechanically assisted bi-
parting cover.
2. The solvent storage tank will be enclosed.
3. The enclosed solvent storage tank along with associated control
valves, pump and piping will be installed and programmed to provide an
automated operating sequence.
4. The size of the tank will be 16'' W x 20'' L x 12'' H.
5. The cover will only be opened when the parts are being placed in
or removed from the tank.
III. Evaluation of State's Submittal
As noted previously, EPA has approved Wisconsin's rule NR 423 as
meeting the RACT requirements of the Act. Under sections
423.03(3)(d)3., and (j), sources may comply through an alternate method
approved by WDNR, providing that it achieves emission reductions
equivalent to that achieved under a freeboard ratio of 1.0.
Additionally, this alternate must be submitted to, and approved by,
EPA.
To demonstrate that the proposed alternate method of control is
equivalent to the level of control that would be achieved under a
freeboard ratio of 1.0, GEM relied on emission factors developed by EPA
and contained in the fifth edition of AP-42, dated January 1995. GEM
estimated that evaporative emissions from the cold cleaner operating
with a freeboard ratio of 1.0 and uncovered when in use (as allowed
under Wisconsin's rule), would be 0.35 pounds of VOC per day. The VOC
emissions resulting from the proposed enclosed system were estimated to
be 0.33 pounds per day.
The State has determined that the alternate control system proposed
by GEM meets the requirements of NR 423, as approved by EPA, and is
thus sufficient to meet the requirements of RACT. Furthermore, by
complying through the proposed alternate control method, the GEM
facility will be achieving greater emission reductions than it would
had it complied through the freeboard ratio specified in rule 423.
The proposed alternate control system has been reviewed by EPA, as
well as the procedures used to establish this alternate system. The
alternate control system will result in a net environmental benefit and
is consistent with the RACT regulation promulgated by the State and
approved by EPA.
IV. Final Rulemaking Action
The EPA approves Wisconsin's site-specific SIP revision for
incorporation into the State's federally enforceable ozone SIP.
Because EPA considers this action noncontroversial and routine, we
are approving it without prior proposal. This action will become
effective on September 16, 1996. However, if we receive adverse
comments by August 16, 1996, EPA will publish a document that withdraws
this action.
V. Miscellaneous
A. Applicability to Future SIP Decisions
Nothing in this action should be construed as permitting, allowing
or establishing a precedent for any future request for revision to any
SIP. The EPA shall consider each request for revision to the SIP in
light of specific technical, economic, and environmental factors and in
relation to relevant statutory and regulatory requirements.
B. Executive Order 12866
This action has been classified as a Table 3 action for signature
by the Regional Administrator under the procedures published in the
Federal Register on January 19, 1989 (54 FR 2214), as revised by a July
10, 1995 memorandum from Mary Nichols, Assistant Administrator for Air
and Radiation. The Office of Management and Budget has exempted this
regulatory action from E.O. 12866 review.
C. Regulatory Flexibility
Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA
must prepare a regulatory flexibility analysis assessing the impact of
any proposed or final rule on small entities (5 U.S.C. 603 and 604).
Alternatively, EPA may certify that the rule will not have a
significant impact on a substantial number of small entities. Small
entities include small businesses, small not-for-profit enterprises,
and government entities with jurisdiction over populations of less than
50,000.
This approval does not create any new requirements. Therefore, I
certify that this action does not have a significant impact on any
small entities affected. Moreover, due to the nature of the Federal-
State relationship under the Act, preparation of the regulatory
flexibility analysis would constitute Federal inquiry into the economic
reasonableness of the State action. The Act forbids EPA to base its
actions concerning SIPs on such grounds. Union Electric Co. v. U.S.
EPA, 427 U.S. 246, 256-66 (1976).
D. Unfunded Mandates
Under Section 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), 2 U.S.C. 1532, the EPA must prepare a
budgetary impact statement to accompany any proposed or final rule that
includes a Federal mandate that may result in estimated costs to State,
local, or tribal governments in the aggregate; or to the private
sector, of $100 million or more. Under Section 205, 2 U.S.C. 1532, the
EPA must select the most cost-effective and least burdensome
alternative that achieves the objectives of the rule and is consistent
with statutory requirements. Section 203, 2 U.S.C. 1532, requires the
EPA to establish a plan for informing and advising any small
governments that may be significantly or uniquely impacted by the rule.
The EPA has determined that the approval action promulgated today
does not include a Federal mandate that may result in estimated costs
of $100 million or more to either State, local, or tribal governments
in the aggregate, or to the private sector.
This Federal action approves pre-existing requirements under State
or local law, and imposes no new Federal requirements. Accordingly, no
additional costs to State, local, or tribal governments, or the private
sector, result from this action.
E. Petitions for Judicial Review
Under Section 307(b)(1) of the Act, petitions for judicial review
of this
[[Page 37218]]
action must be filed in the United States Court of Appeals for the
appropriate circuit by September 16, 1996. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this rule for the purposes of judicial review, nor does
it extend the time within which a petition for judicial review may be
filed and shall not postpone the effectiveness of such rule or action.
This action may not be challenged later in proceedings to enforce its
requirements (see Section 307(b)(2)).
