Project XL Site-specific Rulemaking for OSi Specialties, Inc., 
Sistersville, WV

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: The EPA is implementing a project under the Project XL program 
for the OSi Specialties, Inc. plant, a wholly owned subsidiary of Witco 
Corporation, located near Sistersville, West Virginia (the 
``Sistersville Plant''). The terms of the XL project are defined in a 
Final Project Agreement (``FPA'') which was made available for public 
review and comment. See 62 FR 34748, June 27, 1997. Following a review 
of the public comments, the FPA was signed by delegates from the EPA, 
the West Virginia Division of Environmental Protection (``WVDEP'') and 
Witco Corporation on October 17, 1997. The EPA is today publishing a 
direct final rule, applicable only to the Sistersville Plant, to 
facilitate implementation of the XL project.
    Today's action is a site-specific regulatory deferral from the 
Resource Conservation and Recovery Act (RCRA) organic air emission 
standards, commonly known as RCRA Subpart CC. The applicability of this 
site-specific deferral is limited to two existing hazardous waste 
surface impoundments, and is conditioned on the Sistersville Plant's 
compliance with air emission and waste management requirements that 
have been developed under this XL project. The air emission and waste 
management requirements are set forth in today's rulemaking. Today's 
action is intended to provide site-specific regulatory changes to 
implement this XL project. The agency expects this XL project to result 
in superior environmental performance at the Sistersville Plant, while 
deferring significant capital expenditures, and thus providing cost 
savings for the Sistersville Plant.

DATES: This direct final rule is effective on April 1, 1998, unless 
relevant adverse comments are received by March 27, 1998. If such 
comments are received, EPA will publish timely notice

[[Page 11125]]

in the Federal Register withdrawing this rule.
    Comments: Public comments on this rulemaking will be accepted until 
April 1, 1998.
    Public Hearing: A public hearing will be held, if requested, to 
provide interested persons an opportunity for verbal presentation of 
data, views, or arguments concerning this site-specific rule to 
implement the Sistersville Plant's XL project. If anyone contacts the 
EPA requesting to speak at a public hearing by March 16, 1998, a public 
hearing will be held on March 20, 1998.

I. Authority

    This regulation is being published under the authority of sections 
1006, 2002, 3001-3007, 3010, and 7004 of the Solid Waste Disposal Act 
of 1970, as amended by the Resource Conservation and Recovery Act, as 
amended (42 U.S.C. 6905, 6912, 6921-6927, 6930, and 6974).

II. Background

A. Overview of Project XL

    This site-specific regulation will implement a project developed 
under Project XL, an EPA initiative to allow regulated entities to 
achieve better environmental results at less cost. Project XL--
``eXcellence and Leadership''-- was announced on March 16, 1995, as a 
central part of the National Performance Review and the EPA's effort to 
reinvent environmental protection. See 60 FR 27282 (May 23, 1995). 
Project XL provides a limited number of private and public regulated 
entities an opportunity to develop their own pilot projects to provide 
regulatory flexibility that will result in environmental protection 
that is superior to what would be achieved through compliance with 
current and reasonably anticipated future regulations. These efforts 
are crucial to the Agency's ability to test new regulatory strategies 
that reduce regulatory burden and promote economic growth while 
achieving better environmental and public health protection. The Agency 
intends to evaluate the results of this and other Project XL projects 
to determine which specific elements of the project(s), if any, should 
be more broadly applied to other regulated entities for the benefit of 
both the economy and the environment.
    Under Project XL, participants in four categories--facilities, 
industry sectors, governmental agencies and communities--are offered 
the flexibility to develop common sense, cost-effective strategies that 
will replace or modify specific regulatory requirements, on the 
condition that they produce and demonstrate superior environmental 
performance. To participate in Project XL, applicants must develop 
alternative pollution reduction strategies pursuant to eight criteria: 
superior environmental performance; cost savings and paperwork 
reduction; local stakeholder involvement and support; test of an 
innovative strategy; transferability; feasibility; identification of 
monitoring, reporting and evaluation methods; and avoidance of shifting 
risk burden. They must have full support of affected Federal, state and 
tribal agencies to be selected.
    For more information about the XL criteria, readers should refer to 
the two descriptive documents published in the Federal Register (60 FR 
27282, May 23, 1995 and 62 FR 19872, April 23, 1997), and the December 
1, 1995 ``Principles for Development of Project XL Final Project 
Agreements'' document. For further discussion as to how the 
Sistersville Plant XL project addresses the XL criteria, readers should 
refer to the notice of availability for this XL project (62 FR 34748, 
June 27, 1997) and the related documents that were noticed by that 
Federal Register action. Each of these documents is available from the 
docket for this action (see ADDRESSES section of today's preamble).
    The XL program is intended to allow the EPA to experiment with 
untried, potentially promising regulatory approaches, both to assess 
whether they provide benefits at the specific facility affected, and 
whether they should be considered for wider application. Such pilot 
projects allow the EPA to proceed more quickly than would be possible 
when undertaking changes on a

[[Page 11126]]

nationwide basis. As part of this experimentation, the EPA may try out 
approaches or legal interpretations that depart from or are even 
inconsistent with longstanding Agency practice, so long as those 
interpretations are within the broad range of discretion enjoyed by the 
Agency in interpreting statutes that it implements. The EPA may also 
modify rules, on a site-specific basis, that represent one of several 
possible policy approaches within a more general statutory directive, 
so long as the alternative being used is permissible under the statute.
    Adoption of such alternative approaches or interpretations in the 
context of a given XL project does not, however, signal the EPA's 
willingness to adopt that interpretation as a general matter, or even 
in the context of other XL projects. It would be inconsistent with the 
forward-looking nature of these pilot projects to adopt such innovative 
approaches prematurely on a widespread basis without first determining 
whether or not they are viable in practice and successful in the 
particular projects that embody them. Furthermore, as EPA indicated in 
announcing the XL program, the Agency expects to adopt only a limited 
number of carefully selected projects. These pilot projects are not 
intended to be a means for piecemeal revision of entire programs. 
Depending on the results in these projects, EPA may or may not be 
willing to consider adopting the alternative interpretation again, 
either generally or for other specific facilities.
    The EPA believes that adopting alternative policy approaches and 
interpretations, on a limited, site-specific basis and in connection 
with a carefully selected pilot project, is consistent with the 
expectations of Congress about EPA's role in implementing the 
environmental statutes (so long as the Agency acts within the 
discretion allowed by the statute). Congress' recognition that there is 
a need for experimentation and research, as well as ongoing re-
evaluation of environmental programs, is reflected in a variety of 
statutory provisions, such as section 8001 of RCRA.

B. Overview of the OSi Sistersville Plant XL Project

1. Introduction
    The EPA is today publishing a temporary deferral of RCRA Subpart CC 
applicable to the Sistersville Plant, to implement key provisions of 
this Project XL initiative. Today's site-specific temporary deferral 
supports a Project XL FPA that has been developed by the OSi 
Sistersville Plant XL stakeholder group. This group consisted of 
representatives from the Sistersville Plant, EPA, WVDEP, and the 
community around the Sistersville Plant. Environmental organizations 
were encouraged to participate in the stakeholder process; in response, 
a representative from the Natural Resources Defense Council (NRDC) 
participated in and provided valuable input to the development of this 
XL Project and the FPA.
    The FPA is available for review in the docket for today's action 
and also is available on the world wide web at http://www.epa.gov/
ProjectXL. A Federal Register document was published June 27, 1997 at 
62 FR 34748 to notify the public of the details of this XL project and 
to solicit comments on the specific provisions of the FPA, which 
embodies the Agency's intent to implement this project. The FPA 
addresses the eight Project XL criteria, and the expectation of the 
Agency that this XL project will meet those criteria. Those criteria 
are: (1) Environmental performance superior to what would be achieved 
through compliance with current and reasonably anticipated future 
regulations; (2) cost savings or economic opportunity, and/or decreased 
paperwork burden; (3) stakeholder support; (4) test of innovative 
strategies for achieving environmental results; (5) approaches that 
could be evaluated for future broader application; (6) technical and 
administrative feasibility; (7) mechanisms for monitoring, reporting, 
and evaluation; and (8) consistency with Executive Order 12898 on 
Environmental Justice (avoidance of shifting of risk burden). The FPA 
specifically addresses the manner in which the project is expected to 
produce, measure, monitor, report, and demonstrate superior 
environmental benefits.
2. OSi Sistersville Plant XL Project Description and Environmental 
Benefits
    The Sistersville Plant is a specialty chemical manufacturer of 
silicone products and is located near Sistersville, West Virginia along 
the east side of the Ohio River. The Sistersville plant produces a 
family of man-made organo-silicone chemicals which are used in industry 
and homes throughout the world. The organo-silicones have applications 
in electronic equipment; aircraft, missile, and space technology; 
appliance, automotive and metal working production; textile, paper, 
plastics, and glass fabrication; rubber products; paint, polish, and 
cosmetics; food processing and preparation; building and highway 
construction and maintenance; and chemical reactions and processes.
    For this XL Project, the Sistersville Plant will install an 
incinerator and route the process vents from its polyether methyl 
capper (``capper'') unit to that incinerator for control of organic air 
emissions. The Sistersville Plant expects to begin implementing these 
organic air emission controls by April of 1998. There are no currently-
applicable regulations that require the Sistersville Plant to install 
this incinerator or to control the organic emissions from the capper 
unit. The EPA anticipates that these controls will be required for the 
Sistersville Plant under the National Emission Standard for Hazardous 
Air Pollutants for the source category Miscellaneous Organic Chemical 
Production and Processes (``MON''), scheduled to be published under the 
authority of Section 112 of the Clean Air Act (``CAA''). The MON is 
currently scheduled to be published as a final rulemaking in November 
of 2000, with air emission controls expected to be required 
approximately three years later. Under this XL project, the 
Sistersville Plant will install and operate organic air emission 
controls on the capper unit approximately five years earlier than EPA 
expects the controls to be required by the MON. Based on current 
production levels, the Sistersville Plant estimates these incinerator 
vent controls will reduce the facility's organic air emissions by about 
309,000 pounds per year.
    The Sistersville Plant will also recover and reuse an estimated 
500,000 pounds per year of methanol that would otherwise be disposed of 
through the on-site wastewater treatment system, and will reduce 
approximately 50,000 pounds per year of organic air emissions from the 
wastewater treatment system. These modifications will reduce sludge 
generation from the wastewater system, that would otherwise be disposed 
of in an onsite landfill, by an estimated 815,000 pounds per year. In 
addition, the Sistersville Plant has committed to conduct a waste 
minimization/pollution prevention (``WMPP'') study which is expected to 
result in additional reductions in waste generation at the facility. 
These initiatives are described further in section III of today's 
preamble. Absent today's action, there are no existing or anticipated 
applicable regulations that would require the Sistersville Plant to 
perform the environmentally beneficial measures of the methanol 
recovery and WMPP initiatives.
    As an incentive for the Sistersville Plant to install the 
incinerator vent controls, recover and re-use the

[[Page 11127]]

methanol, and to conduct the WMPP study, the EPA considers it 
appropriate to temporarily defer other regulatory requirements 
applicable to the Sistersville Plant. Specifically, EPA is today 
publishing a temporary, conditional deferral from the RCRA Subpart CC 
organic air emission control requirements applicable to the facility's 
two hazardous waste surface impoundments. The deferral is from the RCRA 
Subpart CC surface impoundment standards codified at 40 CFR 264.1085 
and 40 CFR 265.1086, as well as associated requirements that are 
referenced in or by 40 CFR 264.1085 and 265.1086 that would otherwise 
apply to the two hazardous waste surface impoundments. The provisions 
of 40 CFR 264.1085 and 265.1086 would have required the Sistersville 
Plant to install organic vapor suppressing covers on the two existing 
hazardous waste surface impoundments. The deferred provisions 
referenced in or by 40 CFR 264.1085 and 265.1086 are the compliance 
assurance requirements that directly relate to the air emission control 
requirements for surface impoundments codified at 40 CFR 264.1085 and 
265.1086. Since EPA is today temporarily deferring the requirements for 
the Sistersville Plant to comply with the RCRA Subpart CC air emission 
control requirements applicable to its two hazardous waste surface 
impoundments, EPA is also temporarily deferring those requirements 
directly related to air emission controls on surface impoundments; 
specifically, the inspection and monitoring requirements codified at 40 
CFR 264.1088 and 265.1089, the recordkeeping requirements codified at 
40 CFR 264.1089 and 265.1090, and the reporting requirements codified 
at 40 CFR 264.1090, as each relate to the two hazardous waste surface 
impoundments at the Sistersville Plant.
    The Sistersville Plant estimates that, if implemented, installation 
and operation of the required RCRA Subpart CC air emission controls on 
the two surface impoundments would result in a total organic emission 
reduction of 45,000 pounds per year. In lieu of installing surface 
impoundment covers to comply with RCRA Subpart CC (either in absence of 
this XL project, or when this project concludes), the Sistersville 
Plant plans to close the two hazardous waste impoundments, and install 
two wastewater treatment tanks to serve in their place. The replacement 
wastewater treatment tanks would most likely be exempt from RCRA 
requirements, under 40 CFR 264.1(g)(6) and 40 CFR 265.1(c)(10); thus, 
the RCRA Subpart CC standards would not be applicable to those tanks. 
There are no currently-applicable regulations that would require air 
emission controls on such tanks; however, the Agency anticipates that 
the MON will be applicable to such tanks, and may require that they be 
equipped with organic emission controls. Therefore, it is reasonable to 
assume that in absence of this XL Project, the organic air emissions 
attributed to the Sistersville Plant's two hazardous waste surface 
impoundments would be transferred to two RCRA-exempt wastewater 
treatment tanks, and would not be controlled for approximately five 
years.
3. Economic Benefits
    The Sistersville Plant estimates that the costs it will incur as a 
result of the RCRA Subpart CC standards being applicable to its two 
hazardous waste surface impoundments would be $2,500,000. Of that 
total, $2,000,000 would be for construction of wastewater treatment 
tanks to replace the surface impoundments, and $500,000 would be for 
performance of RCRA closure requirements for the two existing hazardous 
waste impoundments. In contrast to these compliance options, the 
Sistersville Plant estimates that the cost to install the incinerator 
and the process vent controls on the capper unit, to implement the 
methanol recovery operation, and to conduct the WMPP initiatives will 
be $700,000.
    The Sistersville Plant considers it economically beneficial to 
spend the resources to install a thermal incinerator and process vent 
controls five years before those controls are likely to be required by 
federal regulation, and to implement a methanol recovery operation and 
implement a WMPP study, in exchange for deferring for five years the 
cost of $2,500,000 that they estimate would be required to implement 
their planned approach to the RCRA Subpart CC surface impoundment 
requirements.
4. Stakeholder Involvement
    Stakeholder involvement during the Project development stage was 
cultivated in several ways. The methods included communicating through 
the media (newspaper and radio announcements), directly contacting 
interested parties, and offering an educational program on the 
regulatory programs impacted by the XL project. Stakeholders have been 
kept informed on the project status via mailing lists, newspaper 
articles, public meetings and the establishment of a public file at the 
Sistersville Public Library and EPA Region 3 offices.
    A local environmental group, the Ohio Valley Environmental 
Coalition, was contacted but stated that they did not have time to 
participate actively in the development of the XL project. However, a 
representative from NRDC, a national environmental interest group, has 
participated in conference call meetings with the Project XL team and 
provided comments during the development of the FPA. This 
representative continues to be notified of all XL project meetings and 
activities. There are few residences located near the facility, and, 
therefore, few local stakeholders other than employees of the facility 
have expressed interest in actively participating in the development of 
the project. However, the Sistersville Plant has provided stakeholders 
with regular Project development updates by circulating meeting and 
conference call minutes. In June of 1997, an announcement of the 
availability of the draft FPA was published in local newspapers and the 
Federal Register, and the draft FPA was widely distributed for public 
comment. In addition, during the public comment period the Sistersville 
Plant hosted a general public meeting to present the draft FPA. In 
response to a request from the Environmental Defense Fund, EPA extended 
the public comment period on the proposed FPA by 30 days. EPA received 
four very positive comments during the public comment period for the 
draft FPA. After the comment period had closed, a comment letter was 
received from a citizen who was concerned about the installation of 
what he believed was a toxic waste incinerator. EPA has responded to 
this citizen's concern by providing further explanation of the project 
and the environmental benefits that will result from the installation 
and operation of the vent incinerator as well as other aspects of the 
project. Copies of all the comment letters, as well as EPA's response 
to the concerned citizen's letter, are located in the rulemaking Docket 
(see the ADDRESSES section of today's preamble).
    As this XL project continues to be implemented, the stakeholder 
involvement program will shift its focus to ensure that: (1) 
Stakeholders are apprised of the status of project construction and 
operation, and (2) stakeholders have access to information sufficient 
to judge the success of this Project XL initiative. Anticipated 
stakeholder involvement during the term of the project will likely 
include other general public meetings to present periodic status 
reports, availability of

[[Page 11128]]

data and other information generated, and appointment of an OSi 
Sistersville Plant Project XL contact at the facility to serve as a 
resource for the community. In addition to the EPA and WVDEP reporting 
requirements of today's rulemaking, the FPA includes provisions whereby 
the Sistersville Plant will make copies of semiannual and annual 
project reports available to all interested parties. A public file on 
this XL project has been maintained at the local Sistersville library 
throughout project development, and will continue to be updated as the 
project is implemented.
    A detailed description of this program and the stakeholder support 
for this project is included in the Final Project Agreement, which is 
available through the docket or through EPA's Project XL site on the 
Internet (see ADDRESSES section of this preamble).
5. Regulatory Implementation Approach
    Today's action would provide the Sistersville Plant with a 
temporary, conditional deferral from the applicability of certain 
existing RCRA Subpart CC regulatory requirements. This action would 
allow the Sistersville Plant to continue to operate the two hazardous 
waste surface impoundments without installing the organic air emission 
controls that are required for those types of units under the RCRA 
Subpart CC Federal regulations. Today's site-specific deferral from 
RCRA Subpart CC surface impoundment requirements is conditioned upon 
the Sistersville Plant's continuous compliance with the environmentally 
beneficial initiatives that were developed for this XL project. Those 
initiatives are described in Section III.A of today's preamble, and 
further detailed in the FPA.
    The state of West Virginia is not yet authorized under the 
Hazardous and Solid Waste Amendments (HSWA) to implement the RCRA 
Subpart CC air regulations. However, West Virginia regulations, 
codified in 45 Code of State Regulations 25 (``WV 45 CSR 25''), contain 
the same technical requirements as the Federal regulations of RCRA 
Subpart CC. The Sistersville Plant is subject to the West Virginia 
State Regulations, which would include requirements that the two 
hazardous waste surface impoundments be operated with organic air 
emission controls. Thus, to implement this XL project, the WVDEP and 
the Sistersville Plant have negotiated and executed a consent order 
under the authority of W.Va. Code Sec. 22-4-5. A copy of that consent 
order is available in the docket for today's rulemaking. The consent 
order defers application of the organic air emission requirements of WV 
45 CSR 25, which would otherwise be applicable to the hazardous waste 
surface impoundments at the Sistersville Plant. The state consent order 
will implement the deferral from WV 45 CSR 25 for the same effective 
period that today's rulemaking will implement a temporary, conditional 
deferral from Federal RCRA Subpart CC requirements. Essentially, the 
consent order implements this XL project at the State level, while 
today's rulemaking implements the project at the Federal level.
    West Virginia is expected to adopt today's rulemaking during their 
1999 State Legislative Session. After that adoption, WVDEP will 
directly implement the Code of State Regulations (``CSR'') that contain 
the temporary, conditional deferral of today's rulemaking. As with 
today's rulemaking, the state consent order's temporary deferral from 
WV 45 CSR 25 surface impoundment requirements is conditioned upon the 
Sistersville Plant's continuous compliance with the environmentally 
beneficial requirements developed under this XL project. Similarly, 
when today's Federal rulemaking is adopted into the West Virginia CSR, 
as described above, the Sistersville Plant will be required to comply 
with those environmental requirements in order to maintain the 
temporary deferral from surface impoundment requirements of WV 45 CSR 
25. The state adoption of today's rulemaking will result in a slight 
change in the way this XL project is implemented at the state level, 
but it will not result in any changes to the environmentally beneficial 
requirements to which the Sistersville Plant is subject, or to the 
nature of the Sistersville Plant's deferral from hazardous waste 
surface impoundment air emission control requirements.
    It is the intent of the EPA and the WVDEP to incorporate the 
provisions of today's rulemaking and the WV state consent order into 
the Sistersville Plant's permits, as appropriate. This would be 
accomplished in the normal course of reissuance of the RCRA part B 
permit, and in any other permits when issued in their normal course. 
Although today's rulemaking action temporarily defers the applicability 
of RCRA Subpart CC air emission control requirements to the two 
hazardous waste surface impoundments, today's action does not affect 
the Sistersville Plant's RCRA permitting requirements under 40 CFR 
270.27. Those permitting requirements are applicable to air emission 
control equipment operated in accordance with RCRA Subpart CC. Today's 
action temporarily defers the applicability of those air emission 
control requirements to the Sistersville Plant surface impoundments; 
but if there is a time that the Sistersville Plant installs air 
emission controls on those hazardous waste surface impoundments, the 
applicable information would be required to be reflected in the Plant's 
RCRA part B permit.
    The only Federal regulation that today's temporary, conditional 
deferral affects is the RCRA Subpart CC organic air emission standards. 
Furthermore, the only aspect of those standards that today's rulemaking 
affects is the applicability of the organic air emission standards to 
the two hazardous waste surface impoundments at the Sistersville Plant. 
Similarly, the only State regulatory requirements that are affected by 
the state consent order are WV 45 CSR 25 requirements applicable to 
organic air emission controls for the two hazardous waste surface 
impoundments at the Sistersville Plant. The EPA emphasizes that today's 
rulemaking action, and the state consent order that parallels today's 
action, do not affect the provisions or applicability of any other 
existing or future regulations; furthermore, the applicability of 
today's rulemaking and the parallel state consent order are limited in 
scope to the Sistersville Plant.
6. Project Duration and Completion
    As with all XL projects testing alternative environmental 
protection strategies, the term of the Sistersville Plant XL project is 
one of limited duration. Section 264.1080(f)(3) of today's rule 
provides that the temporary deferral of the RCRA Subpart CC air 
emission requirements for the surface impoundments at the Sistersville 
Plant will expire on the ``MON Compliance Date.'' Today's rule defines 
the ``MON Compliance Date'' as three years after the effective date of 
the MON. As described in Section II.B.2 of this preamble, air emission 
controls for the MON source category are scheduled to become final in 
late 2000, and air emission controls for MON sources are to be required 
three years after that date. Accordingly, this XL project will not 
continue after that time, and the Sistersville Plant will thereafter be 
subject to those requirements deferred by today's rule, if applicable. 
However, the Sistersville Plant may propose to EPA a new Project XL to 
take effect after that time.
    Today's rule provides for an orderly transition from the 
requirements of this XL project to those requirements which

[[Page 11129]]

will apply to the facility after the project ends. Pursuant to 40 CFR 
264.1080(f)(3)(iii) and 264.1080(g)(1)(ii) of today's rulemaking, the 
Sistersville Plant is required to submit to EPA an implementation 
schedule specifying how the Sistersville Plant will come into 
compliance with the requirements that are deferred by today's rule. The 
implementation schedule must be submitted to EPA eighteen months prior 
to the MON Compliance Date, and must meet the requirements of 40 CFR 
264.1080(g)(1)(iii) of today's rule. In no event will the 
implementation schedule extend beyond the MON Compliance Date. The 
implementation schedule submitted by the Sistersville Plant must 
contain interim calendar, or ``milestone,'' dates for the purchase and 
installation of equipment, performance testing, and other measures as 
may be necessary for the Sistersville Plant to come into compliance 
with the deferred requirements.
    Today's rule provides that the Sistersville Plant has the option 
within the above-described transitional period to either install 
equipment and take such other steps as may be necessary to comply with 
the deferred requirements (i.e., to bring the surface impoundments into 
compliance with 40 CFR 264.1085), or to install equipment and undertake 
such modifications as may be necessary so as to preclude the 
application of the deferred requirements (i.e., such that 40 CFR 
264.1085 is no longer applicable). Regardless of which approach the 
Sistersville Plant selects, those changes must be fully completed and 
implemented by the MON Compliance Date in order to provide 
uninterrupted environmental benefits, and a seamless transition for the 
Sistersville Plant to move from its XL project requirements to its 
otherwise applicable requirements.
    Because Project XL is a voluntary and experimental program, today's 
rule contains provisions that allow the project to conclude prior to 
the MON Compliance Date, in the event that it is desirable or necessary 
to do so. For example, an early conclusion (or revocation ``for cause'' 
as set forth in 40 CFR 264.1080(f)(3)(iv) of today's rule) would be 
warranted if the project's environmental benefits do not meet the 
Project XL requirement for the achievement of ``superior'' 
environmental results, or if the capper unit is removed from service at 
the facility and no environmental benefits are realized from the air 
emission controls installed on the capper under this XL project. In 
addition, new laws or regulations may become applicable to the 
Sistersville Plant during the project term which might render the 
project impractical, or might contain regulatory requirements that 
supersede the ``superior'' environmental benefits that the Sistersville 
Plant is achieving under this project. Finally, upon reviewing a 
proposed transfer of ownership under 40 CFR 264.1080(f)(7) of today's 
rule, the Agency might determine that a future owner or operator of the 
facility does not adequately implement this XL project. Similarly, the 
Sistersville Plant may also request that the temporary deferral be 
revoked prior to the MON Compliance Date if this experimental project 
does not provide sufficient benefits for the company to justify 
continued participation. If an early conclusion to the project is 
determined to be appropriate, 40 CFR 264.1085(f)(3)(iv) of today's rule 
provides a mechanism for EPA to legally conclude the project prior to 
the MON Compliance Date, which would trigger the eighteen-month 
transitional period described earlier in this preamble discussion.
    While both EPA and the Sistersville Plant have broad discretion and 
latitude to initiate an early conclusion of the project, both expect to 
exercise their good faith and judgment in determining whether 
exercising this option is appropriate. In this respect, and as provided 
in the FPA, EPA expects that it would not be necessary to exercise its 
discretion under this provision to conclude this project for ``minor'' 
noncompliance by the Sistersville Plant. However, as with any failure 
to comply with EPA regulations, the Agency retains its full authority 
to bring a formal or informal enforcement action (if necessary) to 
bring the Sistersville Plant back into compliance. Though the Agency 
has the option of concluding this project for noncompliance, EPA 
expects that this would be appropriate in response to material 
noncompliance by the Sistersville Plant (e.g., substantial or repeated 
violations, failure to disclose material facts during the FPA 
development, etc.).
    Finally, in the event that the XL project concludes (for whatever 
reason) prior to the MON Compliance Date, the Sistersville Plant must 
submit and comply with an implementation schedule (as described earlier 
in this preamble section) setting forth how the Sistersville Plant will 
come into compliance within the eighteen-month transitional period. The 
schedule shall reflect the Sistersville Plant's intent to use its best 
efforts to come into compliance as quickly as practicable within the 
eighteen-month transitional period; in no event will the implementation 
schedule extend beyond the MON Compliance Date. There is an important 
exception to the provision for an eighteen-month transitional period: 
if project conclusion occurs less than eighteen months prior to the MON 
Compliance Date, the Sistersville Plant still must come into compliance 
with all applicable requirements no later than the MON Compliance Date. 
In other words, concluding the project during the eighteen-month 
transitional period prior to the MON Compliance Date does not operate 
to extend the temporary conditional deferral beyond the MON Compliance 
Date.

III. Regulatory Requirements and Performance Standards

A. Capper Unit Control Requirements

    Under this XL project, the Sistersville Plant will reduce air 
emissions and waste that would otherwise be generated by its capper 
unit. The organic air emission reduction will be accomplished by 
installing a vent system to collect the organic emissions from the 
capper unit process vents, and routing the organic vent stream to a 
thermal incinerator. The thermal vent incinerator will be required to 
reduce the organics in the vent stream 98% by weight. Upon installation 
of the thermal incinerator, the Sistersville Plant will conduct an 
initial performance test for the thermal incinerator, to determine an 
operating temperature that they consider appropriate to achieve the 
required 98% organic reduction. At that time, the Sistersville Plant 
will also conduct an initial inspection of the vent system to ensure 
there are no leaks, so that all organics collected in the vent system 
are routed to the thermal incinerator for treatment. Throughout the 
duration of this project, the Sistersville Plant will continue to 
monitor the thermal incinerator operating temperature, as an indication 
that the thermal vent incinerator is achieving the 98% organic 
reduction from the process vent stream. The EPA considers it 
appropriate to assume that operating the thermal vent incinerator at or 
above the temperature determined in the initial performance test will 
provide an adequate level of assurance that the incinerator is 
achieving an organic destruction efficiency of 98% by weight. However, 
since the achievement of the environmental benefits from this XL 
project is very dependent on the effectiveness of this thermal vent 
incinerator, the EPA may, at some time during the project term, 
consider it appropriate to request that the Sistersville Plant verify 
that the incinerator operating temperature is

[[Page 11130]]

achieving the required 98% reduction in organics.

B. Methanol Recovery

    In addition to the organic air emission controls that the 
Sistersville Plant shall operate, this XL project will also result in a 
reduction of methanol discharged from the capper unit to the facility's 
wastewater treatment system. To accomplish this, the Sistersville Plant 
will operate a methanol recovery system that will collect the methanol 
that would otherwise be sent to the facility's on-site wastewater 
treatment system. The Sistersville Plant will attempt to recycle and 
re-use the collected methanol on-site, in lieu of virgin methanol. If 
the Sistersville Plant does not consider such re-use to be an 
economically feasible endeavor, it will attempt to sell the collected 
methanol to other facilities, for use in place of virgin methanol or 
for recovery. Only if these first two approaches are not viable, would 
the Sistersville Plant dispose of the collected methanol by routing it 
for thermal recovery, treatment, or bio-treatment. For the expected 
term of this XL project, the Sistersville Plant shall ensure that no 
more than five percent of the collected methanol is subject to bio-
treatment; however, if the project is revoked prior to the MON 
Compliance Date, the Sistersville Plant is not subject to that five 
percent limit.

C. Waste Minimization/Pollution Prevention Study

    An additional environmental benefit of this XL project is that the 
Sistersville Plant will conduct a WMPP study to explore new initiatives 
that could be employed at the facility. The Sistersville Plant shall 
conduct the WMPP study to identify and implement source reduction 
opportunities (as defined in EPA's Hazardous Waste Minimization 
National Plan, November 1994 (EPA 530/R-94/045) (``National Plan'')). 
The purposes of source reduction opportunities are to: (1) Reduce the 
amount of any hazardous substance, pollutant, or contaminant entering a 
waste stream or otherwise released into the environment (including 
fugitive emissions) prior to recycling, treatment, or disposal; and (2) 
reduce the hazards to public health and the environment associated with 
the release of such substances, pollutants, or contaminants. For those 
waste streams that the Sistersville Plant concludes cannot be reduced 
at the source, the WMPP initiative will identify sound recycling 
opportunities (as defined in the National Plan), and evaluate the 
feasibility of implementing such recycling opportunities at the 
Sistersville Plant. One focus of the WMPP initiative shall be the 
reduction of specific constituents listed in 40 CFR 264.1080(f)(8) of 
today's rulemaking, to the extent that such constituents are found in 
waste streams at the Sistersville Plant.

IV. Additional Information

A. Public Hearing

    A public hearing will be held, if requested, to provide opportunity 
for interested persons to make verbal presentations regarding this 
regulation in accordance with 42 U.S.C. Sec. 7004(b)(1); 40 CFR part 
25. Persons wishing to make a verbal presentation on the site specific 
rule to implement the OSi Sistersville Plant XL project should contact 
Mr. Tad Radzinski of the Region 3 EPA office, at the address given in 
the ADDRESSES section of this document. Any member of the public may 
file a written statement before the hearing, or after the hearing, to 
be received by EPA no later than March 27, 1998. Written statements 
should be sent to EPA at the addresses given in the ADDRESSES section 
of this document. If a public hearing is held, a verbatim transcript of 
the hearing, and written statements provided at the hearing will be 
available for inspection and copying during normal business hours at 
the EPA addresses for docket inspection given in the ADDRESSES section 
of this preamble.

B. Executive Order 12866

    Under Executive Order 12866 (58 FR 51735, October 4, 1993) the 
Agency must determine whether the regulatory action is ``significant'' 
and therefore subject to Office of Management and Budget (OMB) review 
and the requirements of the Executive Order. The Order defines 
``significant regulatory action'' as one that is likely to result in a 
rule that may:
    (1) Have an annual effect on the economy of $100 million or more or 
adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety in State, local, or tribal governments or communities;
    (2) Create a serious inconsistency or otherwise interfere with an 
action taken or planned by another agency;
    (3) Materially alter the budgetary impact of entitlement, grants, 
user fees, or loan programs of the rights and obligations of recipients 
thereof; or
    (4) Raise novel legal or policy issues arising out of legal 
mandates, the President's priorities, or the principles set forth in 
the Executive Order.
    Because the annualized cost of this final rule would be 
significantly less than $100 million and would not meet any of the 
other criteria specified in the Executive Order, it has been determined 
that this rule is not a ``significant regulatory action'' under the 
terms of Executive Order 12866, and is therefore not subject to OMB 
review.
    Executive Order 12866 also encourages agencies to provide a 
meaningful public comment period, and suggests that in most cases the 
comment period should be sixty days. However, in consideration of the 
very limited scope of today's site-specific rulemaking, and the 
previous opportunity for public comment (which included the details of 
today's rulemaking) that EPA provided with the proposed FPA (see 62 FR 
34748, June 27, 1997), the EPA considers twenty-one days to be 
sufficient in providing a meaningful public comment period for today's 
action.

C. Regulatory Flexibility

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to conduct a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements unless the agency certifies 
that the rule will not have a significant economic impact on a 
substantial number of small entities. Small entities include small 
businesses, small not-for-profit enterprises, and small governmental 
jurisdictions. This rule will not have a significant impact on a 
substantial number of small entities because it only affects one 
facility, the OSi Sistersville Plant in Sistersville, West Virginia. 
The Sistersville Plant is not a small entity. Therefore, EPA certifies 
that this action will not have a significant economic impact on a 
substantial number of small entities.
    The Congressional Review Act, 5 U.S.C. Section 801 et seq., as 
added by the Small Business Regulatory Enforcement Fairness Act of 
1996, generally provides that before a rule may take effect, the Agency 
promulgating the rule must submit a rule report, which includes a copy 
of the rule, to each House of the Congress and the Comptroller General 
of the United States. Section 804, however, exempts from Section 801 
the following types of rules: rules of particular applicability; rules 
relating to Agency management or personnel; and rules of Agency 
organization, procedure, or practice that do not substantially affect 
the rights or obligations of non-Agency parties. 5 U.S.C. Section 
804(3). EPA is not required to submit a rule report regarding today's 
action under Section

[[Page 11131]]

801 because this is a rule of particular applicability.

D. Paperwork Reduction Act

    This action applies only to one company, and therefore requires no 
information collection activities subject to the Paperwork Reduction 
Act, and therefore no information collection request (ICR) will be 
submitted to OMB for review in compliance with the Paperwork Reduction 
Act, 44 U.S.C. 3501, et seq.

E. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures to State, local, and tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
one year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective or least burdensome alternative if the 
Administrator publishes with the final rule an explanation of why that 
alternative was not adopted. Before EPA establishes any regulatory 
requirements that may significantly or uniquely affect small 
governments, including tribal governments, it must have developed under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
requirements.
    As noted above, this rule is applicable only to the OSi 
Sistersville Plant, located near Sistersville, West Virginia. The EPA 
has determined that this rule contains no regulatory requirements that 
might significantly or uniquely affect small governments. EPA has also 
determined that this rule does not contain a Federal mandate that may 
result in expenditures of $100 million or more for State, local, and 
tribal governments, in the aggregate, or the private sector in any one 
year. Thus, today's rule is not subject to the requirements of sections 
202 and 205 of the UMRA.

F. April 1, 1998 Effective Date

    The Agency finds that good cause exists under section 3010(b)(3) of 
RCRA (42 U.S.C. 6903(b)(3)) to publish this site-specific regulation as 
a direct final rule with an effective date less than six months from 
date of promulgation. Today's direct final rule affects only one 
facility, and is limited in its scope to a temporary conditional 
deferral of a relatively narrow set of RCRA regulations. As such, it is 
designed to provide greater flexibility only to the OSi Specialties, 
Inc. Sistersville Plant, and does not impose additional regulatory 
requirements on other regulated entities.
    In addition, the local community to be affected by this XL project, 
as well as other interested stakeholders, have been involved during the 
development of this pilot project. In addition to regular consultations 
and information exchanges, there also was opportunity for the public to 
comment on the features represented by this XL project. A Federal 
Register publication announced the availability of the proposed FPA for 
this XL project, and provided a 30 day public comment period. See 62 FR 
34748, June 27, 1997. Today's direct final rule does not represent a 
significant departure from the terms and conditions contained in that 
FPA.

    2. Section 264.1080 is amended by adding paragraphs (f) and (g) to 
read as follows:


Sec. 264.1080  Applicability.

* * * * *
    (f) This paragraph (f) applies only to the facility commonly 
referred to as the OSi Specialties Plant, located on State Route 2, 
Sistersville, West Virginia (``Sistersville Plant'').
    (1)(i) Provided that the Sistersville Plant is in compliance with 
the requirements of paragraph (f)(2) of this section, the requirements 
referenced in paragraphs (f)(1)(iii) and (f)(1)(iv) of this section are 
temporarily deferred, as specified in paragraph (f)(3) of this section, 
with respect to the two hazardous waste surface impoundments at the 
Sistersville Plant. Beginning on the date that paragraph (f)(1)(ii) of 
this section is first implemented, the temporary deferral described in 
this paragraph shall no longer be effective.
    (ii)(A) In the event that a notice of revocation is issued pursuant 
to paragraph (f)(3)(iv) of this section, the requirements referenced in 
paragraphs (f)(1)(iii) and (f)(1)(iv) of this section are temporarily 
deferred, with respect to the two hazardous waste surface impoundments, 
provided that the Sistersville Plant is in compliance with the 
requirements of paragraphs (f)(2)(ii), (f)(2)(iii), (f)(2)(iv), 
(f)(2)(v), (f)(2)(vi) and (g) of this section, except as provided under 
paragraph (f)(1)(ii)(B) of this section. The temporary deferral 
described in the previous sentence shall be effective beginning on the 
date the Sistersville Plant receives written notification of 
revocation, and continuing for a maximum period of 18 months from that 
date, provided that the Sistersville Plant is in compliance with

[[Page 11132]]

the requirements of paragraphs (f)(2)(ii), (f)(2)(iii), (f)(2)(iv), 
(f)(2)(v), (f)(2)(vi) and (g) of this section at all times during that 
18-month period. In no event shall the temporary deferral continue to 
be effective after the MON Compliance Date as defined in paragraph 
(f)(6) of this section.
    (B) In the event that a notification of revocation is issued 
pursuant to paragraph (f)(3)(iv) of this section as a result of the 
permanent removal of the capper unit from methyl capped polyether 
production service, the requirements referenced in paragraphs 
(f)(1)(iii) and (f)(1)(iv) of this section are temporarily deferred, 
with respect to the two hazardous waste surface impoundments, provided 
that the Sistersville Plant is in compliance with the requirements of 
paragraphs (f)(2)(vi), and (g) of this section. The temporary deferral 
described in the previous sentence shall be effective beginning on the 
date the Sistersville Plant receives written notification of 
revocation, and continuing for a maximum period of 18 months from that 
date, provided that the Sistersville Plant is in compliance with the 
requirements of paragraphs (f)(2)(vi) and (g) of this section at all 
times during that 18-month period. In no event shall the temporary 
deferral continue to be effective after the MON Compliance Date.
    (iii) The standards in Sec. 264.1085 of this part, and all 
requirements referenced in or by Sec. 264.1085 that otherwise would 
apply to the two hazardous waste surface impoundments, including the 
closed-vent system and control device requirements of Sec. 264.1087 of 
this part.
    (iv) The reporting requirements of Sec. 264.1090 of this part that 
are applicable to surface impoundments and/or to closed-vent systems 
and control devices associated with a surface impoundment.
    (2) Notwithstanding the effective period and revocation provisions 
in paragraph (f)(3) of this section, the temporary deferral provided in 
paragraph (f)(1)(i) of this section is effective only if the 
Sistersville Plant meets the requirements of paragraph (f)(2) of this 
section.
    (i) The Sistersville Plant shall install an air pollution control 
device on the polyether methyl capper unit (``capper unit''), implement 
a methanol recovery operation, and implement a waste minimization/
pollution prevention (``WMPP'') project. The installation and 
implementation of these requirements shall be conducted according to 
the schedule described in paragraphs (f)(2)(i) and (f)(2)(vi) of this 
section.
    (A) The Sistersville Plant shall complete the initial start-up of a 
thermal incinerator on the capper unit's process vents from the first 
stage vacuum pump, from the flash pot and surge tank, and from the 
water stripper, no later than April 1, 1998.
    (B) The Sistersville Plant shall provide to the EPA and the West 
Virginia Department of Environmental Protection, written notification 
of the actual date of initial start-up of the thermal incinerator, and 
commencement of the methanol recovery operation. The Sistersville Plant 
shall submit this written notification as soon as practicable, but in 
no event later than 15 days after such events.
    (ii) The Sistersville Plant shall install and operate the capper 
unit process vent thermal incinerator according to the requirements of 
paragraphs (f)(2)(ii)(A) through (f)(2)(ii)(D) of this section.
    (A) Capper unit process vent thermal incinerator.
    (1) Except as provided under paragraph (f)(2)(ii)(D) of this 
section, the Sistersville Plant shall operate the process vent thermal 
incinerator such that the incinerator reduces the total organic 
compounds (``TOC'') from the process vent streams identified in 
paragraph (f)(2)(i)(A) of this section, by 98 weight-percent, or to a 
concentration of 20 parts per million by volume, on a dry basis, 
corrected to 3 percent oxygen, whichever is less stringent.
    (i) Prior to conducting the initial performance test required under 
paragraph (f)(2)(ii)(B) of this section, the Sistersville Plant shall 
operate the thermal incinerator at or above a minimum temperature of 
1600 Fahrenheit.
    (ii) After the initial performance test required under paragraph 
(f)(2)(ii)(B) of this section, the Sistersville Plant shall operate the 
thermal incinerator at or above the minimum temperature established 
during that initial performance test.
    (iii) The Sistersville Plant shall operate the process vent thermal 
incinerator at all times that the capper unit is being operated to 
manufacture product.
    (2) The Sistersville Plant shall install, calibrate, and maintain 
all air pollution control and monitoring equipment described in 
paragraphs (f)(2)(i)(A) and (f)(2)(ii)(B)(3) of this section, according 
to the manufacturer's specifications, or other written procedures that 
provide adequate assurance that the equipment can reasonably be 
expected to control and monitor accurately, and in a manner consistent 
with good engineering practices during all periods when emissions are 
routed to the unit.
    (B) The Sistersville Plant shall comply with the requirements of 
paragraphs (f)(2)(ii)(B)(1) through (f)(2)(ii)(B)(3) of this section 
for performance testing and monitoring of the capper unit process vent 
thermal incinerator.
    (1) Within sixty (60) days after thermal incinerator initial start-
up, the Sistersville Plant shall conduct a performance test to 
determine the minimum temperature at which compliance with the emission 
reduction requirement specified in paragraph (f)(4) of this section is 
achieved. This determination shall be made by measuring TOC minus 
methane and ethane, according to the procedures specified in paragraph 
(f)(2)(ii)(B) of this section.
    (2) The Sistersville Plant shall conduct the initial performance 
test in accordance with the standards set forth in paragraph (f)(4) of 
this section.
    (3) Upon initial start-up, the Sistersville Plant shall install, 
calibrate, maintain and operate, according to manufacturer's 
specifications and in a manner consistent with good engineering 
practices, the monitoring equipment described in paragraphs 
(f)(2)(ii)(B)(3)(i) through (f)(2)(ii)(B)(3)(iii) of this section.
    (i) A temperature monitoring device equipped with a continuous 
recorder. The temperature monitoring device shall be installed in the 
firebox or in the duct work immediately downstream of the firebox in a 
position before any substantial heat exchange is encountered.
    (ii) A flow indicator that provides a record of vent stream flow to 
the incinerator at least once every fifteen minutes. The flow indicator 
shall be installed in the vent stream from the process vent at a point 
closest to the inlet of the incinerator.
    (iii) If the closed-vent system includes bypass devices that could 
be used to divert the gas or vapor stream to the atmosphere before 
entering the control device, each bypass device shall be equipped with 
either a bypass flow indicator or a seal or locking device as specified 
in this paragraph. For the purpose of complying with this paragraph, 
low leg drains, high point bleeds, analyzer vents, open-ended valves or 
lines, spring-loaded pressure relief valves, and other fittings used 
for safety purposes are not considered to be bypass devices. If a 
bypass flow indicator is used to comply with this paragraph, the bypass 
flow indicator shall be installed at the inlet to the bypass line used 
to divert gases and vapors from the closed-vent system to

[[Page 11133]]

the atmosphere at a point upstream of the control device inlet. If a 
seal or locking device (e.g., car-seal or lock-and-key configuration) 
is used to comply with this paragraph, the device shall be placed on 
the mechanism by which the bypass device position is controlled (e.g., 
valve handle, damper levels) when the bypass device is in the closed 
position such that the bypass device cannot be opened without breaking 
the seal or removing the lock. The Sistersville Plant shall visually 
inspect the seal or locking device at least once every month to verify 
that the bypass mechanism is maintained in the closed position.
    (C) The Sistersville Plant shall keep on-site an up-to-date, 
readily accessible record of the information described in paragraphs 
(f)(2)(ii)(C)(1) through (f)(2)(ii)(C)(4) of this section.
    (1) Data measured during the initial performance test regarding the 
firebox temperature of the incinerator and the percent reduction of TOC 
achieved by the incinerator, and/or such other information required in 
addition to or in lieu of that information by the WVDEP in its approval 
of equivalent test methods and procedures.
    (2) Continuous records of the equipment operating procedures 
specified to be monitored under paragraph (f)(2)(ii)(B)(3) of this 
section, as well as records of periods of operation during which the 
firebox temperature falls below the minimum temperature established 
under paragraph (f)(2)(ii)(A)(1) of this section.
    (3) Records of all periods during which the vent stream has no flow 
rate to the extent that the capper unit is being operated during such 
period.
    (4) Records of all periods during which there is flow through a 
bypass device.
    (D) The Sistersville Plant shall comply with the start-up, 
shutdown, maintenance and malfunction requirements contained in 
paragraphs (f)(2)(ii)(D)(1) through (f)(2)(ii)(D)(6) of this section, 
with respect to the capper unit process vent incinerator.
    (1) The Sistersville Plant shall develop and implement a Start-up, 
Shutdown and Malfunction Plan as required by the provisions set forth 
in paragraph (f)(2)(ii)(D) of this section. The plan shall describe, in 
detail, procedures for operating and maintaining the thermal 
incinerator during periods of start-up, shutdown and malfunction, and a

where:

Cij, Coj = Concentration of sample component j 
of the gas stream at the inlet and outlet of the control device, 
respectively, dry basis, parts per million by volume.
Ei, Eo = Mass rate of TOC (minus methane and 
ethane) at the inlet and outlet of the control device, respectively, 
dry basis, kilogram per hour.
Mij, Moj = Molecular weight of sample 
component j of the gas stream at the inlet and outlet of the control 
device, respectively, gram/gram-mole.
Qi, Qo = Flow rate of gas stream at the inlet 
and outlet of the control device, respectively, dry standard cubic 
meter per minute.
K2 = Constant, 2.494 x 10-6 (parts per 
million)-1 (gram-mole per standard cubic meter) 
(kilogram/gram) (minute/hour), where standard temperature (gram-mole 
per standard cubic meter) is 20  deg.C.

    (C) The percent reduction in TOC (minus methane and ethane) shall 
be calculated as follows:

response factor criteria in section 3.1.2(a) of Method 21 of 40 CFR 
part 60, appendix A shall be for the average composition of the process 
fluid not each individual volatile organic compound in the stream. For 
process streams that contain nitrogen, air, or other inerts which are 
not organic hazardous air pollutants or volatile organic compounds, the 
average stream response factor shall be calculated on an inert-free 
basis.
    (B) If no instrument is available at the plant site that will meet 
the performance criteria specified in paragraph (f)(5)(ii)(A) of this 
section, the instrument readings may be adjusted by multiplying by the 
average response factor of the process fluid, calculated on an inert-
free basis as described in paragraph (f)(5)(ii)(A) of this section.
    (iii) The detection instrument shall be calibrated before use on 
each day of its use by the procedures specified in Method 21 of 40 CFR 
part 60, appendix A.
    (iv) Calibration gases shall be as follows:
    (A) Zero air (less than 10 parts per million hydrocarbon in air); 
and
    (B) Mixtures of methane in air at a concentration less than 10,000 
parts per million. A calibration gas other than methane in air may be 
used if the instrument does not respond to methane or if the instrument 
does not meet the performance criteria specified in paragraph 
(f)(5)(ii)(A) of this section. In such cases, the calibration gas may 
be a mixture of one or more of the compounds to be measured in air.
    (v) The Sistersville Plant may elect to adjust or not adjust 
instrument readings for background. If the Sistersville Plant elects to 
not adjust readings for background, all such instrument readings shall 
be compared directly to the applicable leak definition to determine 
whether there is a leak. If the Sistersville Plant elects to adjust 
instrument readings for background, the Sistersville Plant shall 
measure background concentration using the procedures in 40 CFR 63.180 
(b) and (c). The Sistersville Plant shall subtract background reading 
from the maximum

[[Page 11138]]

concentration indicated by the instrument.
    (vi) The arithmetic difference between the maximum concentration 
indicated by the instrument and the background level shall be compared 
with 500 parts per million for determining compliance.

where:

CTOC = Concentration of TOC (minus methane and ethane), 
dry basis, parts per million by volume.
Cji = Concentration of sample components j of sample i, 
dry basis, parts per million by volume.
n = Number of components in the sample.
x = Number of samples in the sample run.

    (C) The concentration of TOC shall be corrected to 3 percent oxygen 
if a combustion device is the control device.
    (1) The emission rate correction factor or excess air, integrated 
sampling and analysis procedures of Method 3B of 40 CFR part 60, 
appendix A shall be used to determine the oxygen concentration 
(%O2d). The samples shall be taken during the same time that 
the TOC (minus methane or ethane) samples are taken.
    (2) The concentration corrected to 3 percent oxygen (Cc) 
shall be computed using the following equation:
[GRAPHIC] [TIFF OMITTED] TR06MR98.005

where:

Cc = Concentration of TOC corrected to 3 percent oxygen, 
dry basis, parts per million by volume.
Cm = Concentration of TOC (minus methane and ethane), dry 
basis, parts per million by volume.
%O2d = Concentration of oxygen, dry basis, percent by 
volume.

    (iv) To determine compliance with the 98 percent reduction 
requirement of paragraph (f)(2)(ii)(A)(1) of this section, the 
Sistersville Plant shall use Method 18 of 40 CFR part 60, appendix A; 
alternatively, any other method or data that has been validated 
according to the applicable procedures in Method 301 of 40 CFR part 63, 
appendix A may be used. The following procedures shall be used to 
calculate percent reduction efficiency:
    (A) The minimum sampling time for each run shall be 1 hour in which

taken. If grab sampling is used, then the samples shall be taken at 
approximately equal intervals in time such as 15 minute intervals 
during the run.
    (B) The mass rate of TOC minus methane and ethane (Ei, 
Eo) shall be computed. All organic compounds (minus methane 
and ethane) measured by Method 18 of 40 CFR part 60, Appendix A are 
summed using the following equations:
[GRAPHIC] [TIFF OMITTED] TR06MR98.006

where:

Cij, Coj = Concentration of sample component j 
of the gas stream at the inlet and outlet of the control device, 
respectively, dry basis, parts per million by volume.
Ei, Eo = Mass rate of TOC (minus methane and 
ethane) at the inlet and outlet of the control device, respectively,

    (5) At the time of the initial performance test of the process vent 
thermal incinerator required under paragraph (f)(2)(ii)(B) of this 
section, the Sistersville Plant shall inspect each closed vent system 
according to the procedures specified in paragraphs (f)(5)(i) through 
(f)(5)(vi) of this section.
    (i) The initial inspections shall be conducted in accordance with 
Method 21 of 40 CFR part 60, appendix A.
    (ii)(A) Except as provided in paragraph (f)(5)(ii)(B) of this 
section, the detection instrument shall meet the performance criteria 
of Method 21 of 40 CFR part 60, appendix A, except the instrument 
response factor criteria in section 3.1.2(a) of Method 21 of 40 CFR 
part 60, appendix A shall be for the average composition of the process 
fluid not each individual volatile organic compound in the stream. For 
process streams that contain nitrogen, air, or other inerts which are 
not organic hazardous air pollutants or volatile organic compounds, the 
average stream response factor shall be calculated on an inert-free 
basis.
    (B) If no instrument is available at the plant site that will meet 
the performance criteria specified in paragraph (f)(5)(ii)(A) of this 
section, the instrument readings may be adjusted by multiplying by the 
average response factor of the process fluid, calculated on an inert-
free basis as described in paragraph (f)(5)(ii)(A) of this section.
    (iii) The detection instrument shall be calibrated before use on 
each day of its use by the procedures specified in Method 21 of 40 CFR 
part 60, appendix A.
    (iv) Calibration gases shall be as follows:
    (A) Zero air (less than 10 parts per million hydrocarbon in air); 
and
    (B) Mixtures of methane in air at a concentration less than 10,000 
parts per million. A calibration gas other than methane in air may be 
used if the instrument does not respond to methane or if the instrument 
does not meet the performance criteria specified in paragraph 
(f)(5)(ii)(A) of this section. In such cases, the calibration gas may 
be a mixture of one or more of the compounds to be measured in air.
    (v) The Sistersville Plant may elect to adjust or not adjust 
instrument readings for background. If the Sistersville Plant elects to 
not adjust readings for background, all such instrument readings shall 
be compared directly to the applicable leak definition to determine 
whether there is a leak. If the Sistersville Plant elects to adjust 
instrument readings for background, the Sistersville Plant shall 
measure background concentration using the procedures in 40 CFR 
63.180(b) and (c). The Sistersville Plant shall subtract background 
reading from the maximum concentration indicated by the instrument.
    (vi) The arithmetic difference between the maximum concentration 
indicated by the instrument and the background level shall be compared 
with 500 parts per million for determining compliance.
    (6) Definitions of terms as used in paragraphs (f) and (g) of this 
section.
    (i) Closed vent system is defined as a system that is not open to 
the atmosphere and that is composed of piping, connections and, if 
necessary, flow-inducing devices that transport gas

[[Page 11146]]

or vapor from the capper unit process vent to the thermal incinerator.
    (ii) No detectable emissions means an instrument reading of less 
than 500 parts per million by volume above background as determined by 
Method 21 in 40 CFR part 60.

virgin methanol as an ingredient (including uses as an intermediate) or 
as an effective substitute for a commercial product following 
reclamation of the methanol subsequent to its collection.
    (v) Thermal recovery/treatment includes the use of collected 
methanol in fuels blending or as a feed to any combustion device to the 
extent permitted by federal and state law.
    (vi) Bio-treatment includes the treatment of the collected methanol 
through introduction into a biological treatment system, including the 
treatment of the collected methanol as a waste stream in an on-site or 
off-site wastewater treatment system. Introduction of the collected 
methanol to the on-site wastewater treatment system will be limited to 
points downstream of the surface impoundments, and will be consistent 
with the requirements of federal and state law.
    (vii) Start-up shall have the meaning set forth at 40 CFR 63.2.
    (viii) Flow indicator means a device which indicates whether gas 
flow is present in the vent stream, and, if required by the permit for 
the thermal incinerator, which measures the gas flow in that stream.
