40 CFR Part 52
[WI69-01-7295a; FRL 5552-1]
Approval and Promulgation of State Implementation Plan;
Wisconsin; GenCorp Inc. Site-Specific SIP Revision
AGENCY: Environmental Protection Agency (EPA).
[[Page 45328]]
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) approves a revision
to the Wisconsin State Implementation Plan (SIP) for ozone that was
submitted on November 17, 1995. This revision is an alternative control
method for controlling volatile organic compound (VOC) emissions from
storage tanks at the GenCorp Inc.-Green Bay facility. The EPA has
approved Wisconsin's general rule for the storage of VOCs. The approved
rule states that any deviation from the specifically required control
methods found in the State's rule must be proven to be equivalent in
controlling the VOC emissions before being approved into the SIP.
Because GenCorp Inc. has chosen a different control method than those
listed specifically in Wisconsin's rule, a site-specific SIP revision
is required to evaluate the control method being used at the Green Bay
facility. 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 October 28, 1996, unless
EPA receives adverse or critical comments by September 30, 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. EPA,
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. EPA, Region 5, Air and Radiation
Division, 77 West Jackson Boulevard, Chicago, Illinois 60604. (Please
telephone Douglas Aburano at (312) 353-6960 before visiting the Region
5 Office.)

SUPPLEMENTARY INFORMATION:
I. Background Information
Wisconsin rule NR 419 is currently approved into the Wisconsin SIP.
Part 419.05 applies to the storage of volatile organic compounds
(VOCs). Rule 419.05 requires the use of specific control methods or
equally effective alternative control methods approved by both the
Wisconsin Department of Natural Resources (WDNR) and Environmental
Protection Agency (EPA). As part of a proposed project at the GenCorp
Inc.-Green Bay facility, a tank used to store acrylonitrile, a VOC,
will be constructed and be subject to the requirements of 419.05. Since
the GenCorp facility will not be using the controls specified in Rule
419.05, WDNR has submitted a site-specific SIP revision to obtain
federal approval of the alternative control methods that the GenCorp
facility will be employing. The WDNR has made the determination that
the controls that the GenCorp facility will be using are more effective
than the controls required by Rule 419.05.
II. Evaluation of State Submittal
The GenCorp facility proposes to construct a styrene-butadiene-
acrylonitrile latex manufacturing project. As part of this project a
vessel used to store acrylonitrile will be necessary. A vessel of this
type is subject to the requirements of Wisconsin Rule NR 419.05.
Acrylonitrile will be unloaded from a railcar, approximately one
26,000 gallon railcar will be unloaded per month. The railcars will be
connected to the unloading rack piping through reinforced hoses. One or
two hoses will convey liquid while another will return any vapor
displaced from the storage tank (vapor balance system). Unloading is
accomplished with a self-priming centrifugal pump. The liquid is
transferred through 3'' welded carbon steel piping to the storage tank.
Acrylonitrile will be stored in a 50,000 gallon horizontal (carbon
steel) pressure vessel. The tank will be located in a watertight
containment basin constructed adjacent to the styrene storage tank
area. The storage tank will be operated at an average pressure of 5
psi, with an over-pressure safety relief set at 100 psi. In addition to
the safety relief, the tank is equipped with a rupture disk and
telltale gage. The tank will be padded with nitrogen gas to maintain
working pressure above one atmosphere to enable pumping raw material to
the polymerization vessels. The acrylonitrile tank will be a new, butt-
welded tank, with a separate containment system surrounding the tank.
The emissions from storage tanks can be divided into two
categories: standing storage losses and working losses. Standing
storage loss is the expulsion of vapor from a tank through vapor
expansion and contraction, which are the result of changes in
temperature and barometric pressure. Working losses are emissions that
occur during filling operations.
The controls specifically required by Rule 419.05, floating roofs,
vapor condensation systems, and vapor holding tanks, are used to
control both types of emissions.
Floating roofs are used to reduce emissions that occur when the
storage tanks are being refilled. Vapor condensation systems will
collect and condense any VOC emissions exiting through vents when the
pressure in a tank increases due to temperature changes or filling of
the tank. Vapor holding tanks are also used to collect emissions that
would exit through vents due to pressure changes. These last two
control devices are usually not used in combination with floating roofs
because the floating roofs will minimize working loss emissions
significantly and would not require additional control.
The WDNR has approved GenCorp-Inc.'s proposed alternative storage
tank controls as being more effective than the controls required by
Rule 419.05. The use of a low-pressure tank will eliminate the standing
storage losses and the use of a vapor recovery system will virtually
eliminate any working losses as well. It is estimated that GenCorp-
Inc.'s proposed controls will achieve an additional 1,113 pounds of VOC
per year in reductions above the controls specifically mentioned in
Rule 419.05.
III. Final Action
The EPA is publishing this action without prior proposal because
the Agency views this as a noncontroversial amendment and anticipates
no adverse comments. However, in a separate document in this Federal
Register publication, the EPA is proposing to approve the SIP revision
should adverse or critical comments be filed. This action will be
effective October 28, 1996 unless, by September 30, 1996, adverse or
critical comments are received.
If the EPA receives such comments, this action will be withdrawn
before the effective date by publishing a subsequent document that will
withdraw the final action. All public comments received will be
addressed in a subsequent final rule based on this action serving as a
proposed rule. The
[[Page 45329]]
EPA will not institute a second comment period on this action. Any
parties interested in commenting on this action should do so at this
time. If no such comments are received, the public is advised that this
action will be effective October 28, 1996.
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any state implementation plan. Each request for revision to
the state implementation plan shall be considered separately in light
of specific technical, economic, and environmental factors and in
relation to relevant statutory and regulatory requirements.
The EPA approves the condition from Wisconsin's construction permit
#95-CHB-407 That requires the use of a pressure vessel storage tank
with a vapor balance system for storage of acrylonitrile which will be
used in the process of manufacturing styrene-butadiene-acrylonitrile
latex making this condition federal enforceable.
IV. Administrative Requirements
A. 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 2214-2225), as revised by a
July 10, 1995 memorandum from Mary Nichols, Assistant Administrator for
Air and Radiation. The Office of Management and Budget (OMB) has
exempted this regulatory action from E.O. 12866 review.
B. Regulatory Flexibility Act
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.
SIP approvals under section 110 and subchapter I, part D of the
Clean Air Act do not create any new requirements but simply approve
requirements that the State is already imposing. Therefore, because the
Federal SIP approval does not impose any new requirements, the
Administrator certifies that it does not have a significant impact on
any small entities affected. Moreover, due to the nature of the
Federal-State relationship under the CAA, preparation of a flexibility
analysis would constitute Federal inquiry into the economic
reasonableness of state action. The Clean Air Act forbids EPA to base
its actions concerning SIPs on such grounds. Union Electric Co. v. U.S.
EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).
C. Unfunded Mandates
Under Section 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), signed into law on March 22, 1995, 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
private sector, of $100 million or more. Under Section 205, 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 requires EPA to establish a plan for
informing and advising any small governments that may be significantly
or uniquely impacted by the rule.
EPA has determined that the approval action promulgated 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 to the private sector, result from this
action.
D. Petitions for Judicial Review
Under section 307(b)(1) of the Act, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by October 28, 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).)

(94) A revision to the ozone State Implementation Plan (SIP) was
submitted by the Wisconsin Department of Natural Resources on November
17, 1995. This revision consists of a site-specific revision for the
GenCorp Inc.-Green Bay facility. This revision is required under
Wisconsin's federally approved rule, NR 419.05. The storage
requirements contained in NR 419.05 specifically require floating
roofs, vapor condensation systems, and vapor holding tanks, or an
equally effective alternative control method approved by the Wisconsin
Department of Natural Resources and U.S. EPA. The GenCorp Inc.-Green
Bay facility has chosen to utilize a pressure vessel storage tank with
a vapor balance system, as specified in Permit 95-CHB-407 which was
issued on August 29, 1995. This pressure vessel will be used for the
storage of acrylonitrile that will be used to manufacture styrene-
butadiene-acrylonitrile latex.
(i) Incorporation by reference. The following sections of the
Wisconsin air pollution construction permit 95-CHB-407 are incorporated
