What actually matters in this document.

Text

SUMMARY: The EPA is implementing a project under the Project XL program

for the Merck & Co., Inc. (Merck) Stonewall Plant, in Elkton, Virginia.

The terms of the project are defined in a Final Project Agreement (FPA)

which is available in the docket for this action. In addition, EPA is

promulgating today a site-specific rule, applicable only to the Merck

Stonewall Plant, to facilitate implementation of the project.

This site-specific rule provides regulatory changes under the Clean

Air Act and the Resource Conservation and Recovery Act (RCRA) to

implement Merck's XL project, which will result in superior

environmental performance and, at the same time, provide Merck with

greater operational flexibility. The site-specific rule changes the

requirements under the Clean Air Act which apply to the Merck Stonewall

Plant for the prevention of significant deterioration of air quality

and certain new source performance standards. EPA also is promulgating

a site-specific rulemaking under RCRA to provide regulatory changes

pertaining to air emissions standards.

DATES: This rule is effective on October 8, 1997.

ADDRESSES: Docket. A docket containing supporting information used in

developing this rulemaking is available for public inspection and

copying at U.S. EPA, Region III, 841 Chestnut Street, Philadelphia, PA,

19107-4431, (215) 566-2064, during normal business hours, and at EPA's

This regulation is being promulgated under the authority of

sections 101(b)(1), 110, 111, 161-169, 169A, and 301(a)(1) of the Clean

Air Act, and sections 1006, 2002, 3001-3007, and 3010 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, and 6930).

EPA has determined that this rulemaking is subject to the provisions of

section 307(d) of the Clean Air Act.

II. Background

A. Overview of Project XL

This site-specific rule is designed to implement a project

developed under Project XL, an important EPA initiative to allow

regulated entities to achieve better environmental results at less

cost. Project XL--for ``excellence and leadership''--was announced on

March 16, 1995, as a central part of the National Performance Review's

and 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, if any, should be more broadly applied to other regulated

entities to the benefit of both the economy and the environment.

In 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.1 They must have full support of affected

Federal, state and tribal agencies to be selected.

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

\1\ For more information about the XL criteria, readers should

refer to the May 23, 1995 Federal Register notice (60 FR 27282) and

the December 1, 1995 ``Principles for Development of Project XL

Final Project Agreements'' document, both contained in the docket

for this action.

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

The XL program is intended to allow 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 EPA to proceed more quickly than would be required to undertake

changes on a nationwide basis. As part of this experimentation, EPA may

try out approaches or legal

[[Page 52623]]

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. EPA may also modify rules

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 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 finding out

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.

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 sections 101(b) and 103 of the Clean Air

Act. In some cases, as in this XL project, such experimentation

requires an alternative regulatory approach that, while permissible

under the statute, was not the one adopted by EPA historically or for

general purposes.

B. Overview of the Merck XL Project

1. Introduction

This site-specific rule supports a proposed permit and Project XL

Final Project Agreement (FPA) that have been developed by the Merck XL

stakeholder group, namely Merck, EPA, Virginia Department of

Environmental Quality (VADEQ), U.S. Department of the Interior (DOI)/

National Park Service (NPS), and community representatives. On March

31, 1997, EPA published a notice of proposed rulemaking to seek public

comment on the proposed site-specific rule. See 62 FR 15304-15322. In

this notice, EPA also sought public comment on the proposed FPA and the

project generally. At the request of the Southern Environmental Law

Center, a public hearing was held on April 14, 1997, in Harrisonburg,

Virginia. The comment period closed on May 15, 1997. EPA received 60

comment letters during the public comment period, and 8 comment letters

after the close of the comment period. EPA's response to the key issues

raised by commenters is contained in Section IV of this preamble. A

separate Response to Comments Document, which fully addresses the

comments, is contained in the docket for this action and is available

on the world wide web at http://www.epa.gov/ProjectXL.

The FPA and proposed permit are contained in the docket for today's

action and also are available on the world wide web at http://

www.epa.gov/ProjectXL. The FPA outlines how the project addresses the

Project XL criteria, in particular how the project will produce,

measure, monitor, report, and demonstrate superior environmental

benefits.

The Commonwealth of Virginia conducted the official comment period

for the proposed PSD permit. The Commonwealth's public comment period

for the proposed PSD permit and a proposed variance began on January

28, 1997, and closed on May 30, 1997. The VADEQ held a public hearing

to solicit comment on the proposed permit and variance on February 27,

1997. The VADEQ plans to request the State Air Pollution Control Board

(Board) to adopt the variance in the near future.

In the near future, EPA plans to delegate, with EPA oversight, the

authority to implement and enforce the PSD site-specific rule (40 CFR

52.2454) to the Commonwealth of Virginia. This delegation would

authorize the VADEQ to issue the PSD permit to Merck. The VADEQ expects

to issue the PSD permit after the Board approves the variance, and

after EPA's delegation of authority is effective.

2. Merck XL Project Description

The Merck XL project was described in detail in the preamble to the

proposed site-specific rulemaking. See 62 FR 15305-15306 (March 31,

1997). The goal of the Merck XL project is to develop a regulatory

structure for the Merck Stonewall Plant that both facilitates flexible

manufacturing operations and achieves superior environmental

performance. Merck's XL project seeks to replace the current air

permitting system with a simpler system of compliance with criteria air

pollutant regulations. Through a site-specific rulemaking and

enforceable permit conditions, the facility's total emissions of

criteria pollutants (except lead) 2 would be capped below

the level at which the plant operated over recent years (at

approximately 1500 tons per year (TPY)). Within the site-wide total

emissions cap, the facility will also be subject to individual

pollutant caps (subcaps), established near or below recent actual

emission levels, for sulfur dioxide (SO2), nitrogen oxides

(NOX), and particulate matter with an aerodynamic diameter

less than 10 microns (PM10). In addition to accepting these

site-wide emissions caps, Merck will modify its existing coal-burning

powerhouse to burn natural gas, a cleaner burning fuel that generates

substantially fewer emissions than coal. Either propane or number 2

fuel oil would be used as a backup fuel. This multi-million dollar

project is not otherwise required by regulations and the boilers do not

need to be replaced for other reasons (e.g., operation, age or

capacity). The powerhouse conversion would result in an up-front

estimated reduction of over 900 TPY of actual criteria air pollutants,

primarily SO2 and NOX emissions. After this

powerhouse conversion, Merck would reduce its total emissions cap by 20

percent, thereby permanently retiring at least 300 TPY of criteria

pollutant emissions. Further, Merck also will reduce the pollutant-

specific subcaps for SO2 and NOX by 25 percent

and 10 percent, respectively.

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

\2\ The criteria pollutants included in the total emissions cap

are sulfur dioxide, nitrogen oxides, carbon monoxide, ozone (using

volatile organic compounds as a surrogate), and particulate matter

with aerodynamic diameter less than 10 microns (PM10).

Thus, the total emissions cap includes all existing criteria

pollutants except lead. Merck will comply directly with any

applicable requirements for the control of lead emissions. Merck

currently emits a very low amount of lead emissions (0.3 tons per

year), which will be virtually eliminated when the facility converts

the coal-burning powerhouse to natural gas. Merck also will comply

directly with any applicable requirements for PM2.5 or

new criteria pollutants which are not included in the total

emissions cap.

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

Merck's XL project will be implemented through issuance of a site-

wide PSD permit, authorized by this site-specific rulemaking. Under the

site-specific rule and permit, the Merck Stonewall Plant will be

required to maintain its emissions below the total emissions cap, as

well as the subcaps for SO2, NOX and

PM10. Under the site-

[[Page 52624]]

wide emissions caps, changes or additions to facility operations would

no longer need prior approval under PSD or NSR. The subcaps will keep

SO2 and NOX emissions below recent actual

emission levels and PM10 emissions will not significantly

increase above the recent actual emissions level. The statutory PSD

requirements for the VOC and CO emission increases that are possible

under the total emissions cap will be satisfied pursuant to this site-

specific rule and the PSD permit. So long as the facility complies with

the total emissions cap, subcaps, and other permit requirements, it

would have the flexibility to make modifications and to operate in a

manner that supports Merck's objective to deliver high quality products

quickly and efficiently to improve human and animal health without

undergoing permit review for each modification.

As an alternative to the current PSD permitting system, the total

emissions cap and subcaps will provide an incentive for Merck to

identify and promptly implement ongoing emission reductions at the

facility to provide operating room under the cap for future

modifications and expansions. The XL project also provides an

additional incentive for Merck to minimize emissions--a system of

``tiered'' monitoring, recordkeeping and reporting requirements. The

permit provides that the monitoring, recordkeeping and reporting

requirements become more stringent as the facility's actual emissions

approach the total emissions cap. This tiered monitoring system

provides Merck another built-in incentive to minimize emissions and to

find opportunities to implement emission reductions.

3. Environmental Benefits

The Merck XL Project is designed to deliver superior environmental

performance while allowing flexible operations at the facility. The

site-specific rule and simplified air permit would provide significant

benefits to the environment by substantially reducing pollutant

emissions near the Shenandoah National Park and the surrounding

community.

The Merck Stonewall Plant is located within 2 kilometers of

Shenandoah National Park, a Federal Class I area. The facility's

proximity to this nationally significant resource highlights the need

for serious consideration of opportunities for better protection of the

environment. Certain criteria pollutants have been demonstrated to have

a significant adverse effect on the environmental quality of the

Shenandoah National Park. In particular, SO2 emissions

contribute to visibility problems in the region, and NOX

emissions combine with other chemicals in the atmosphere to form

ground-level ozone, which has been determined to cause vegetation

damage. Emissions of SO2 and NOX also contribute

to the formation of acid rain and associated adverse impacts. Merck's

powerhouse conversion will achieve an up-front reduction of these

pollutants--SO2 emissions are expected to decrease by 679

TPY (94 percent) and NOX emissions are expected to decrease

by 254 TPY (87 percent), from baseline actual emission levels. After

the powerhouse conversion, the total emissions cap and subcaps will

ensure a continuing, permanent reduction of these pollutants, as well

as provide an ongoing incentive to minimize actual emissions to

preserve the operating margin under the caps. Besides the significant

reduction in criteria pollutants resulting from the project, the

conversion to natural gas also will result in a reduction of about 47

TPY (65 percent) of hazardous air pollutants (HAPs), specifically

hydrogen chloride and hydrogen fluoride. These two HAPs are generated

by burning coal and are also associated with the formation of acid

rain. Reducing emissions of these chemicals also will contribute to

efforts to improve air quality in the Shenandoah National Park and the

surrounding community.

Although the facility's VOC and CO emissions would be allowed to

increase above recent actual emission levels (but within the total

emissions cap), there are no identified adverse effects from the

maximum allowable levels of these pollutants under the total emissions

cap. Moreover, the statutory PSD requirements for VOC and CO will be

satisfied pursuant to this site-specific rulemaking and issuance of the

PSD permit. See the preamble to the proposed site-specific rule (62 FR

15309-15312, March 31, 1997).

III. Summary of Regulatory Requirements for the Merck XL Project

A. Clean Air Act

The alternate regulatory system that is established under this

site-specific rule and the permit addresses the existing criteria

pollutants (and does not include lead). Merck will fully comply with

all requirements for the control of HAPs, including the forthcoming

Maximum Achievable Control Technology (MACT) standard for the

pharmaceutical industry. Merck also will comply with all existing and

future environmental requirements not specifically amended pursuant to

EPA's site-specific rulemaking for this project or pursuant to the

variance expected to be approved by the Commonwealth of Virginia.

EPA emphasizes that the alternative approaches to compliance with

Clean Air Act requirements adopted in this rule are being adopted only

for this facility, on a pilot project basis. The approach is not

available to other facilities, and the decision to make it available at

this facility is linked to the full set of the facility's obligations

in this project. Based on the experience in this project, EPA could

propose to adopt such an approach more widely at some future time, but

today's rule is limited to the Merck Stonewall Plant and should not be

interpreted as a more general revision of regulations, or even as

initiating a process toward such a general revision.

1. Prevention of Significant Deterioration

In today's action, EPA is promulgating a site-specific PSD rule for

the Merck Stonewall Plant in order to implement the XL project for the

site. See 40 CFR 52.2454. This site-specific rule replaces (in most

circumstances) the existing PSD rules at 40 CFR 52.21 for the Merck

Stonewall Plant only, and establishes the legal authority to issue the

PSD permit to the Merck Stonewall Plant. The site-specific PSD

requirements were described in detail in the preamble to the proposed

rulemaking. See 62 FR 15309-15312 (March 31, 1997).

The Merck Stonewall Plant is located in an area that currently

meets the NAAQS for all criteria air pollutants (attainment area) and,

thus, the PSD program under part C of title I of the Act applies. The

site-specific rule would authorize a permit to be issued to Merck

based, in part, on the establishment of a site-wide emissions cap for

criteria air pollutants (total emissions cap). The criteria pollutants

included in the total emissions cap are SO2, NOX,

PM10, CO and ozone (using VOC as a surrogate). Thus, all

existing criteria pollutants except lead are included in the total

emissions cap. Merck would comply directly with any applicable

requirements, including the existing PSD regulations at 40 CFR

52.21,3 for the control of lead emissions,

PM2.5,4 and any new criteria pollutants

promulgated by EPA. If in the future EPA were to promulgate standards

for other forms of fine particulates (e.g., PM1.0), Merck

also would be required to comply directly with any associated

[[Page 52625]]

applicable requirements. Further, Merck will comply with any applicable

requirements, including the existing PSD regulations at 40 CFR 52.21

for emissions of non-criteria air pollutants (e.g., hydrogen sulfide,

total reduced sulfur).5

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

\3\ The Commonwealth of Virginia currently implements 40 CFR

52.21 under a delegation of authority from EPA. See 40 CFR 52.2451.

\4\ Particulates with an aerodynamic diameter less than or equal

to a nominal 2.5 micrometers.

\5\ If Merck were to emit significant quantities of non-criteria

air pollutants regulated under 40 CFR 52.21, Merck would be required

to comply directly with any applicable requirements for these

pollutants. For the Merck Stonewall Plant only, EPA extends the

policy set forth in the October 16, 1995 policy memorandum entitled

``Definition of Regulated Pollutant for Particulate Matter for

Purposes of Title V,'' which is contained in the docket for this

rulemaking, to consider PM10 as the regulated form of

particulate matter for purposes of PSD applicability; however, this

rulemaking does not extend the policy to PM2.5.

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

Merck will be allowed to vary its emission levels under the total

emissions cap, constrained by the individual pollutant subcaps. Changes

at the facility that might otherwise be considered to result in

emission increases would no longer need prior approval by the

permitting authority under PSD or minor NSR, based on the facility's

site-wide, federally-enforceable emission limitations. The emission

limitations would keep SO2 and NOX emissions well

below recent actual emissions. The emission limitations for

PM10 will not significantly increase above the recent actual

emissions level. Emissions of VOC and CO will not have subcaps,

however, the statutory PSD requirements for increases of VOC and CO are

satisfied pursuant to this site-specific rulemaking.

The site-specific PSD rule (40 CFR 52.2454) is being promulgated as

proposed, with the exception of a clarification that the site-specific

rule does not apply in lieu of the PSD regulations at 40 CFR 52.21 for

PM2.5. See 40 CFR 52.2454(a)(2). This revision to the final

rule is described further in Section IV.C.3 of this preamble. In

response to public comments, the proposed PSD permit has been changed

to address issues regarding requirements for the control of

PM2.5, RCRA hazardous waste accumulation and/or storage

vessels, and monitoring device data availability. These issues and

associated permit changes are described in sections V.C, VI, and

VIII.D, respectively, of the Response to Comments Document (contained

in the docket and on the world wide web at http://www.epa.gov/

ProjectXL).

2. New Source Performance Standards

EPA also is promulgating a site-specific rule which establishes an

alternative means of compliance for the Merck Stonewall Plant for two

New Source Performance Standards (NSPS)--Subpart Db (Standards of

Performance for Industrial-Commercial-Institutional Steam Generating

Units) and Subpart Kb (Standards of Performance for Volatile Organic

Liquid Storage Vessels). See 40 CFR 60.1(d); 40 CFR 60.49b(u); and 40

CFR 60.112b(c). For NSPS other than Subpart Kb that may become

applicable to the site in the future, EPA is promulgating an

alternative compliance provision that would allow the facility the

option of complying with the NSPS by reducing its site-wide emissions

caps. However, under this latter approach, EPA has an opportunity to

require Merck to comply directly with the applicable NSPS. These

alternate compliance provisions are necessary to implement a simpler

compliance approach for the facility that is more consistent with the

principles of the site-wide emissions caps. The NSPS alternative means

of compliance is described in detail in the preamble to the proposed

site-specific rulemaking. See 62 FR 15314-15315 (March 31, 1997).

The NSPS site-specific rule is being promulgated as proposed, with

the exception of a correction to a citation. In 40 CFR 60.49b(u)(1)

(pertaining to alternate compliance for the new natural gas-fired

boilers), EPA has corrected an error in the citation contained in the

proposed rule such that the second sentence now reads, ``The

requirements of this paragraph shall apply, and the requirements of 40

CFR 60.40b through 60.49b(t) shall not apply, to the natural gas-fired

boilers installed pursuant to 40 CFR 52.2454(g).'' The proposed rule

cited 40 CFR 60.49b, rather than 40 CFR 60.49b(t), which would have

mistakenly included as not applicable the new paragraph 40 CFR

60.49(u).

3. State Implementation Plan Requirements

On January 28, 1997, VADEQ requested public comment on a proposed

variance for the Merck Stonewall Plant, pursuant to section 10.1-1307

of the Virginia Air Pollution Control Law.6 The VADEQ plans

to request that the State Air Pollution Control Board approve the

variance for Merck in the near future. Among other things, the variance

would provide Merck an alternate means of compliance with newly-

applicable criteria pollutant regulations promulgated by the VADEQ.

This alternate compliance option would allow Merck in most situations

either to comply with new criteria pollutant regulations as written, or

to reduce the total emissions cap (or subcaps, depending on the

pollutant) by an equivalent amount of emission reductions. VADEQ also

plans in the future to promulgate a source-specific regulation for the

Merck XL project that would serve as an alternate to the regulations

cited in the permit. EPA understands that VADEQ plans to submit this

regulation to the EPA for approval as a source-specific SIP revision.

EPA would then take action on the expected source-specific SIP revision

in a future rulemaking action. For a further description of Merck's

compliance with SIP requirements under this XL project, see the

preamble to the proposed site-specific rule (62 FR 15313, March 31,

1997).

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

\6\ This variance provision previously has been approved into

the Virginia SIP at 40 CFR 52.2420(c)(15) and (89).

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

B. Resource Conservation and Recovery Act

In addition to Clean Air Act requirements, today EPA also is

establishing alternate regulatory requirements for the RCRA air

emission standards for the Merck Stonewall Plant. The RCRA subpart AA,

BB, and CC air emission standards under 40 CFR parts 264 and 265 are

applicable to certain existing hazardous waste units at the Merck

Stonewall Plant. These standards also may be applicable to equipment

brought into hazardous waste service in the future. The RCRA air

standards contain both substantive emission control requirements and

administrative requirements (e.g., reporting and recordkeeping)

applicable to certain hazardous waste management units. Under this XL

project, the Merck Stonewall Plant will be subject to a site-specific

exemption from the RCRA air emission standards under 40 CFR parts 264

and 265. Under this XL Project, the hazardous waste management units at

the Merck Stonewall Plant that would otherwise be subject to those 40

CFR parts 264 and 265 standards will be regulated through an

enforceable PSD permit and a preventive maintenance program. See 62 FR

15315 (March 31, 1997).

For hazardous waste tanks and containers located at the Merck

Stonewall Plant, the proposed PSD permit includes air emission control

requirements that are identical to the substantive requirements under

the RCRA air standards. For process vents that would otherwise be

subject to the subpart AA process vent regulations, and for equipment

that would otherwise be subject to the subpart BB equipment leak

regulations, the Merck Stonewall Plant will implement air emission

control requirements that are similar, though not identical, to those

that are included in the nationwide standards.

[[Page 52626]]

For all affected hazardous waste equipment, today's site-specific

regulation will exempt the Merck Stonewall Plant from the

administrative requirements of the RCRA air standards; the proposed PSD

permit and a future the Clean Air Act (CAA) Title V permit, will

subject the plant to alternative administrative requirements. The

nationwide RCRA air standards contain an allowance that a unit operated

with air emission controls, in compliance with a CAA standard in 40 CFR

parts 60, 61, or 63, is exempt from the RCRA standards. Among other

requirements, this nationwide allowance exempts a unit from the

administrative requirements of the RCRA air standards, provided that

the air emission controls on that unit are operated in compliance with

the requirements of the CAA part 60, 61, or 63 standard, including

administrative requirements. See 40 CFR 265.1080(b)(7); 61 FR 59971

(November 25, 1996). In such cases, the administrative requirements

would ultimately be enforceable through a CAA permit. Under this XL

project, the Agency is allowing the Merck Stonewall Plant to comply

with the administrative requirements that will be contained in the

facility's CAA PSD and Title V permits, which is analogous to the

existing nationwide RCRA air standards provision that allows facilities

the alternative to operate air emission controls in compliance with

standards under 40 CFR parts 60, 61 or 63. Thus, the Agency considers

the administrative requirements under this XL project for affected

hazardous waste management units at the Merck Stonewall Plant to be

equivalent to the administrative requirements of the nationwide RCRA

air standards.

The Agency continues to consider the requirements contained in the

proposed PSD permit to be a viable approach to addressing organic air

emission from hazardous waste units at the Merck Stonewall Plant.

Therefore, the site-specific exemption from requirements of 40 CFR

parts 264 and 265 is being finalized today exactly as it was proposed.

See 62 FR 15303 (March 31, 1997). The Response to Comments Document

describes a change to the proposed PSD permit that was made to address

a commenter's question about the permit requirements for RCRA hazardous

waste accumulation and/or storage vessels. This comment and the

associated change to the proposed PSD permit are described in Section

VI of the Response to Comments Document (contained in the docket).

IV. Summary of Response to Key Public Comments

EPA received 60 comment letters on the proposed Merck XL project

during the public comment period. An additional eight comment letters

were received after the close of the comment period. These letters

primarily reflected comments similar to those received during the

comment period; therefore, EPA's response to comments generally

addresses issues raised in the late comments as well. In the following

section, the Agency responds to several of the key issues raised by

commenters. A comprehensive response to comments is contained in a

separate document, ``Merck XL Site-Specific Rulemaking--Response to

Comments Document'' which is contained in the docket and available on

the world wide web at http://www.epa.gov/ProjectXL.

A. General Support of Project

General support for the Merck XL project was expressed by several

citizens, government officials, industry associations, state

environmental agencies, businesses, and the Merck workers union.

Several citizens commented that Merck is a good environmental steward

and a good corporate neighbor. Some commenters expressed that, besides

the project's immediate benefits to environmental quality in the area,

the project will further benefit the community by making the Stonewall

Plant more attractive as a site for product expansion and new product

introduction, resulting in increased employment opportunities for

people living in the Shenandoah Valley. Many comments also supported

the simplified regulatory process and increased operational flexibility

afforded to Merck. Two state environmental agencies commented that the

project is an excellent example of innovative permitting, and commended

EPA for its efforts. These states believe that the project is a great

example of EPA's reinventing environmental regulation initiative, and

will provide significant environmental performance while allowing Merck

the flexibility warranted by such a permit. One state added that it

supports the permit's strong incentives to minimize air emissions of

criteria pollutants on an ongoing basis. Industry associations and

companies commented that the project will benefit future permitting

strategies that seek better ways to protect the environment. A Virginia

industry association urged EPA to advance the project to the

implementation stage where the value of the increased operational

flexibility can be clearly demonstrated.

B. Superior Environmental Performance

1. General

Numerous commenters, including citizens, environmental groups,

state environmental agencies, industry groups, and political officials,

expressed support for the emission reductions that will be achieved by

Merck converting its coal-fired boilers to burn natural gas. Many of

the citizen and environmental group commenters supported the permanent

reduction of criteria air pollutants by 300 TPY, as well as the upfront

reduction of criteria pollutants by 900 TPY, and of hazardous air

pollutants by 47 TPY. These comments specifically addressed the

importance of this project's environmental benefits to Shenandoah

National Park. A citizen commenter added support for the other positive

elements of the project, including the provision that the project does

not allow the sale or acquisition of emission credits, and that annual

or semi-annual reports must be submitted to the project signatories.

2. Level of Emissions Caps

There were some comments from environmental groups and a citizen

regarding the level of reduction of certain emission caps from the

baseline levels. One environmental group questioned why the site-wide

total emissions cap was set at a level of 20% less than recent actual

emissions when there will be a 60% emissions reductions of criteria

pollutants from the replacement of coal-fired boilers.

The baseline for the site-wide emissions cap is the average of

annual actual emissions during the years 1992-93 (approximately 1500

TPY), the recent years most representative of normal facility

operations. See 62 FR 15309 (March 31, 1997). Detailed information

about the establishment of the emissions caps is contained in the

rulemaking docket. The site-wide emissions cap will be reduced by 20%

from the baseline level (i.e., the reduced cap level will be 1200 TPY,

thereby permanently retiring 300 TPY of emissions) after the powerhouse

conversion. Thus, Merck's new ``allowable'' emissions (the cap) will be

20% lower than recent actual emissions. In fact, Merck's allowable

emissions in the baseline period were approximately 2700 TPY, so its

new allowable emissions (i.e., the total emissions cap) will be less

than half of the old allowable limit. The only reason that Merck is

able to reduce its baseline cap by 20% is because of the significant

actual emission reductions that will be

[[Page 52627]]

achieved from the powerhouse conversion (switching from burning coal to

natural gas, a much cleaner burning fuel). The powerhouse conversion

will reduce criteria pollutant emissions by approximately 900 TPY,

bringing post-conversion site-wide actual criteria pollutant emissions

to approximately 600 TPY (i.e., 1500 TPY minus 900 TPY). With the 20%

cap reduction, Merck's ``margin for growth'' under the cap will be

approximately 600 TPY (i.e., 1200 TPY minus 600 TPY). If the cap were

set at the facility's post-powerhouse conversion level, as suggested by

the commenter, Merck would have no operating margin for growth, and,

thus, no incentive to enter into this project or implement the

powerhouse conversion. In order to provide the regulatory and

operational flexibility of this XL project, it is necessary to have an

adequate margin for growth under the cap. EPA anticipates that Merck's

emissions will remain far below the total emissions cap for a long

period of time after the powerhouse conversion, in part because the

tiered monitoring system provides an incentive to minimize emissions.

As long as Merck operates under this PSD permit, Merck will no

longer be able to obtain permits to increase emissions above the cap,

since an exceedance of the total emissions cap is a basis for

termination of the permit. Under the current permitting system, Merck

would not be constrained by a site-wide emissions cap, and could

continue to increase emissions as long as the proper permits were

obtained.

Another environmental group commenter supported the overall

permanent emission reductions that will be achieved (300 TPY), but

expressed concern about the volatile organic compound (VOC) emission

increases allowed under the cap. The commenter expressed concern that

while NOX emissions will initially decrease, the permanent

reduction assured is only 29 TPY (i.e., a 10% reduction of the

NOX subcap from baseline emissions); meanwhile, VOC

emissions can increase substantially above current levels. The

commenter believes that, given that both NOX and VOC

emissions contribute to ozone formation, Merck's contribution to ozone

formation could increase rather than decrease over time. The commenter

suggests that a lower NOX cap could correct this problem.

Alternatively, Merck commented that the setting of the individual

emission caps was the subject of extensive debate during the

stakeholder meetings, and that the levels prescribed in the proposed

permit are the result of full agreement from the stakeholder group.

Merck stated that it is not aware of any new and compelling information

to substantiate any need for changes to the emission caps.

EPA does not believe there is a need to set a lower NOX

cap. The impact of the potential VOC emission increases under the cap

on ozone formation is described elsewhere in this document and in the

preamble to the proposed site-specific rulemaking. See 62 FR 15310

(March 31, 1997). Merck's NOX emissions cap guarantees that

its future actual NOX emissions will always be at least 10%

less than recent actual emissions. Further, Merck's current permitted

NOX emissions are 569 TPY; thus, by taking a NOX

cap at a level that is 10% less than current actual emissions (i.e.,

262 TPY), Merck also is relinquishing the ability to emit NOx at the

currently permitted levels. In the preamble to the proposed site-

specific rulemaking, EPA described an analysis (contained in the

docket) that had been conducted to demonstrate that Merck's worst-case

VOC emissions would continue to provide protection of the ozone NAAQS.

See 62 FR 15310 (March 31, 1997). Because this analysis demonstrates

that Merck's worst-case VOC emissions will continue to provide

protection of the ozone NAAQS, and because Merck's worst-case

NOX emissions will be less than recent emissions, EPA does

not believe that Merck's contribution to ozone formation under this

project would increase rather than decrease over time, compared to

Merck's current emissions levels and its ability to increase emissions

under the current permitting system. Therefore, EPA does not agree that

it is necessary to establish a lower NOX subcap.

3. Volatile Organic Compound (VOC) Emissions

Several citizens and environmental groups expressed concern about

the potential increase in VOC emissions from recent levels, as Merck

operates under the site-wide emissions cap. Some commented that since

there is no specific cap on VOC emissions, Merck would be able to

increase VOCs by about 650 TPY from recent emission levels. One citizen

commented on the tradeoff of VOCs and CO for reductions in other

pollutants, and questioned the value of that tradeoff and whether there

is a way to measure it. Some commenters believed that since VOCs are a

major source of ozone, the potential VOC increases would have a

detrimental effect on respiratory health, the health of the forests in

Shenandoah National Park and elsewhere, tourism, and crop yields.

As Merck operates under the total emissions cap, it is permissible

over time for VOC emissions to increase above the baseline VOC levels.

The baseline VOC emission level is 408 TPY. If all other pollutants

remain at their expected post-powerhouse conversion levels, the maximum

VOC emissions increase (above baseline VOC emissions level) under the

cap would be approximately 650 TPY. It should be noted that if Merck

were to increase VOC emissions by this amount it would no longer have a

margin for growth under the site-wide emissions cap and would have to

implement the most stringent tier of monitoring, recordkeeping and

reporting. Thus, Merck has an incentive not to reach this level of

emissions. Nevertheless, an analysis was conducted to determine the

impact on the ozone NAAQS if Merck were to increase VOC emissions to

the maximum amount under the cap. In the preamble to the proposed site-

specific rulemaking, EPA described an analysis (contained in the

docket) that had been conducted to demonstrate that Merck's worst-case

VOC emissions would continue to provide protection of the ozone NAAQS.

See 62 FR 15310 (March 31, 1997).

The Merck Stonewall Plant is located in an area that is

NOX-limited for ground-level ozone formation. The term

``NOX-limited'' means that the amount of NOX

available is generally the controlling factor in determining how much

ozone will be formed. In a NOX-limited area, reduced

NOX emissions will result in reduced ozone formation, and

increased NOX emissions will result in increased ozone

formation. Further, increased VOC emissions generally will not result

in additional ozone formation unless accompanied by additional

NOX emissions.

A report contained in the docket analyzed the worst case potential

impact of increased VOC emissions on ozone formation in the area, based

on an evaluation of urban airshed modeling developed for State

Implementation Planning purposes in two urban areas. See 62 FR 15310

(March 31, 1997) and the docket. In summary, this report analyzed a

worst case scenario which showed that the expected ozone increase from

Merck's potential VOC emissions would be less than 0.5 parts per

billion (ppb), which is less than 0.5% of the 120 ppb ozone standard,

and 0.625% of the 80 ppb ozone standard. EPA believes that the analysis

portrayed a highly conservative worst case scenario and that the

potential ozone formation would be negligible under actual conditions.

Moreover, the NOX emission reductions achieved as a result

of Merck's powerhouse conversion and the establishment of

[[Page 52628]]

permanent NOx subcaps will help to reduce local ozone formation.

Therefore, EPA believes that the maximum potential VOC emission

increases allowed under Merck's site-wide cap will continue to provide

protection of the ozone NAAQS.

Other commenters stated that the permit's review structure would

put severe limitations on incorporating any future knowledge about VOCs

into the permit's conditions. One citizen commenter suggested that

Merck should be required to contribute to an EPA-approved study of the

contribution of VOCs to air pollution. This commenter expressed the

need to study the effects of the various chemicals that will be emitted

on the natural, historic and human resources of the Shenandoah area.

The proposed PSD permit has numerous provisions that were designed

specifically to address the effects of Merck's VOC emissions. Any

future knowledge about the environmental or public health effects of

VOCs will be implemented in the Merck permit in the following ways.

First, Merck will be required to comply with any generally applicable

future regulation designed to control VOCs, and generally would have

the option to reduce the cap in lieu of directly implementing the

regulation (Section 1.2.2 of the permit). Second, Merck will conduct an

assessment of VOC emissions for impacts on air quality related values

(AQRVs) in Shenandoah National Park if VOC emissions reach specified

levels. See Section 6.2.1 of the permit. Third, Merck is required to

comply directly with any requirements for the control of hazardous air

pollutants (HAPs), including the forthcoming maximum achievable control

technology (MACT) standard for the pharmaceutical industry. Compliance

with the pharmaceutical MACT and other HAP requirements also will

control VOC emissions, because some of the HAPs used or emitted by

Merck are also VOCs. Finally, Merck will conduct property line modeling

of non-HAP VOCs to determine whether the emission levels are protective

of public health. This modeling will be conducted when VOC emissions

reach 125% of the VOC baseline (i.e., 510 TPY) and whenever VOC

emissions increase by additional 100 TPY increments (i.e., 610 TPY, 710

TPY, and 810 TPY). If this modeling assessment predicts an exceedance

of the Significant Ambient Air Concentrations (SAAC), which are based

on a fraction of the Threshold Limit Values 7, Merck must

either demonstrate that the site's emissions produce no endangerment to

human health, or implement changes at the site resulting in ambient

concentrations that are below the SAAC or that are otherwise acceptable

to VADEQ. This permit provision (Section 6.2.2) was developed to

address the community stakeholders' concerns about the potential public

health effects of Merck's VOC emissions. Because the AQRV assessment

and the non-HAP VOC public health assessment are actions that will

happen at some future point in time, if Merck reaches the respective

VOC trigger levels, the permit provides for any new information about

VOCs to be considered at the time the assessments are conducted.

Similarly, any future regulations promulgated to control VOC emissions

will take into account the latest information about the effects of

VOCs.

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

\7\ Threshold Limit Values, established for many chemicals, are

workplace limits based on chronic and acute health effects, and are

listed in the American Conference of Governmental Industrial

Hygienists handbook.

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

While the Merck project does not require that the permit be

reopened to factor in new information about VOCs, the project offers an

important opportunity for stakeholders to raise issues of concern to be

considered at the five-year permit reviews. It is important to note

that the generally applicable PSD regulations do not require that

permits be reopened to incorporate future knowledge about emissions

information. So long as a permittee complies with the emission

limitations and other permit terms, and does not make changes at the

facility that require further permitting review, the permit would not

be required to be reopened to incorporate future information about the

permitted emissions levels.

EPA does not agree that it is necessary under Project XL for Merck

to contribute to an EPA-approved study of the contribution of VOCs to

air pollution. There are already a number of efforts under way to

assess the various public health and environmental effects of VOC

emissions. For years, the Ozone Transport Assessment Group (OTAG) has

undertaken region-wide studies of the effects of VOCs on ozone

formation. Under Section 112(b)(2) of the Clean Air Act, EPA is

required to periodically review the list of HAPs to add pollutants

which may present a threat of adverse human health effects. As for all

HAPs, if any new VOCs are added to the list of HAPs, Merck will be

required to control them in accordance with the applicable HAP

requirements.

4. PM-10 Emissions

A citizen commented that there is no PM10 environmental

benefit in this project, and that even a little benefit would be

appreciated. Merck commented that the powerhouse conversion from coal

to natural gas is estimated to result in a PM10 emissions

decrease of 74,000 pounds per year (37 TPY), which is a 98% reduction

from baseline actual PM10 emissions. Merck stated that the

PM10 cap was set at a level that reflects the lack of

accurate PM10 emission factors and already very low

PM10 emission rates at the plant. Merck commented that no

new and compelling information has been presented to indicate a change

to the PM10 cap is warranted.

The permit establishes a PM10 subcap at the baseline

emissions level of 42 TPY. The PM10 subcap will not be

reduced after the powerhouse conversion. However, as Merck's comment

indicates, the project will result in an upfront reduction of a

substantial amount of PM10, from the burning of natural gas

instead of coal. During the stakeholder discussions in developing this

project, Merck had repeatedly expressed concern about setting a

PM10 subcap at a level that would unnecessarily restrict

future growth of operations, when there might be plenty of room for

expansion of total emissions under the site-wide cap. In other words,

because the baseline PM10 emissions were already relatively

low (42 TPY), a ``reduced'' PM10 cap, similar to that for

SO2 and NOX, could be the limiting factor in

whether Merck would be able to expand operations in the future. That

scenario would be counter to this XL's project's goal of providing

increased operational flexibility. The ambient air quality modeling for

PM10 conducted in support of the proposed permit

demonstrated that the site's current worst-case emission rates do not

cause or contribute to a violation of the NAAQS. See 61 FR 15310 (March

31, 1997). The permit further provides for Merck's ambient impact,

which will include impacts of the PM10 emissions, to be

reevaluated at each five-year review period. Thus, EPA believes that

the level of the PM10 emissions cap established in the

permit is appropriate.

C. National Ambient Air Quality Standards (NAAQS)

1. Future Nonattainment Situation

Two companies located in the Rockingham County, Virginia, area

submitted comments regarding the potential for the area to become

nonattainment for ozone or other pollutants in the future, and

expressed

[[Page 52629]]

concern for the impact of possible additional nonattainment control

strategies on other sources in the area. Under the new PSD permit,

Merck would be required to comply with any new criteria pollutant

regulations, including those that might be promulgated if the area

becomes a nonattainment area in the future; however, Merck generally

would have the option to comply with the new regulations via a cap

reduction. See Section 1.2.2 of the proposed PSD permit. In the

preamble to the proposed rulemaking, EPA explained that the

Commonwealth of Virginia could not take emissions reduction credit in

an attainment plan if Merck chooses the option of reducing its

emissions caps, rather than complying directly with a criteria

pollutant regulation. See 62 FR 15313 (March 31, 1997). These companies

are concerned that they would be required to implement stricter

controls, at greater cost, because Merck's cap reduction would not be

credited for attainment planning purposes. The commenters do not

believe that sources should have to make up for the actual emission

reductions because of the insulation provided to Merck. One company

suggested that EPA should allow it to have the same insulation since

its actual emissions are considerably lower than its permitted

emissions.

Merck commented that it believes there is confusion about the

possibility of more stringent future control requirements for other

nearby facilities under a regional RACT plan as a result of this

project. Merck described its view of the events which would have to

occur before other nearby facilities would be impacted by more

stringent controls, which it believes is an unlikely situation. Merck

also submitted additional technical information prepared by a

consultant relating to Merck's impact on local air quality and the

implications of the new proposed ozone NAAQS.

The area in which the Merck facility is located has been well

documented to be NOX limited for ozone formation. Therefore,

it is most likely that, if the area became nonattainment for the ozone

NAAQS in the future, a control strategy would predominantly target

reductions in NOX emissions, rather than VOC emissions. In

the preamble to the proposed rule, EPA described an analysis which

documented that the worst-case potential VOC emissions under Merck's

cap would continue to provide protection of the ozone NAAQS. See 62 FR

15310 (March 31, 1997).

The planning involved in designing a control strategy to bring an

area into attainment is based on an inventory of actual emissions.

Since Merck will achieve significant actual emission reductions of

NOX from the powerhouse conversion, these low actual

NOX emissions will help to reduce ozone formation and will

benefit any future control strategy efforts. In a sense, it could be

viewed that Merck is complying ``early'' with any future actual

NOX emission reductions that might be required for

nonattainment planning. Similarly, other sources in the area which have

very low actual emissions (e.g., as a result of BACT or comparable

technology) likely would not be targeted for additional controls for

those well-controlled and low-emitting units. Rather, nonattainment

control strategies typically target those sources (both stationary and

mobile sources) which are capable of achieving substantial decreases in

actual emissions.

2. Ozone NAAQS--General

An environmental group commented that the forests of Virginia are

already suffering as a result of both ozone and acid ion deposition,

and suggested that this information should be documented. The commenter

provided information about the rate of decline of oak forests in the

northern mountains of Virginia.

EPA agrees with the commenter that ozone is a cause of degradation

to forests and other vegetation in the Shenandoah area. The proposed

Final Project Agreement describes the adverse effects of ozone and

other pollutants on resources in the Park. The rulemaking docket

includes a copy of the U.S. Department of Interior's Preliminary Notice

of Adverse Impact on Shenandoah National Park (55 FR 38403, September

18, 1990) and the accompanying Technical Support Document. These

documents explain the potential impacts of ozone, NOX, and

SO2 on forests and vegetation, as well as potential impacts

of pollutants on aquatic streams and visibility.

A commenter from a company in Rockingham County commented that

there is no scientific evidence presented in the preamble to the site-

specific rulemaking or background documents that Rockingham County is a

NOX-limited area for ozone. The commenter also suggested

that EPA require baseline air quality monitoring in Rockingham County

to specifically address the importance of VOCs in relation to ozone

transport.

It has been well documented that the area in which the Merck

Stonewall Plant is located is NOX-limited for ozone

formation.8 The Permit Support Document (contained in the

docket) includes additional information and references that the area is

NOX-limited. The OTAG modeling effort of ozone in the

eastern U.S. is one of the largest public-private air quality projects

ever conducted. As part of its key modeling findings related to future

attainment strategies, OTAG found that NOX emission

reductions are more effective than VOC emission reductions in lowering

regional ozone concentrations; NOX reductions decrease ozone

domain wide, while VOC reductions decrease ozone only in urban areas. A

copy of this modeling report is contained in the docket. In its public

comments, Merck submitted additional technical papers for the docket

that document that the area is NOX-limited for ozone

formation.

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

\8\ Ozone Transport Assessment Group, Modeling Report (Draft),

Regional and Urban Scale Modeling Workgroup, Version 1.1., February

12, 1997 (contained in docket).

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

The PSD requirement for pre-construction ambient air quality

monitoring has been satisfied. The docket contains the ambient ozone

monitoring data that satisfies this requirement. EPA disagrees that

additional monitoring should be required within the context of the

Merck XL project to address the importance of VOCs in ozone transport.

These efforts are being undertaken in a much broader context by the

OTAG modeling studies. Further, ozone transport is a regional issue and

it is currently not feasible to study the effects of VOC from a single

source on ozone transport.

3. New Ozone and Particulate Matter NAAQS

Several environmental groups and citizens requested EPA to address

how Merck would comply with the new proposed NAAQS for ozone and fine

particulates. Some commenters expressed concern that they believe the

permit does not account for EPA's proposed new air quality standards,

and allows a long term escape from higher standards, especially

particulates. Some commenters also believe the permit should be

reconsidered to account for PM2.5.

On July 18, 1997, EPA promulgated final rules which revise the

NAAQS for ozone (62 FR 38855-38896) and particulate matter (62 FR

38651-38752). Under EPA's final rule, the NAAQS for particulate matter

is revised in several respects, including the addition of two new

standards for PM2.5 (particulates with an aerodynamic

diameter less than or equal to a nominal 2.5 micrometers). Because

PM2.5 (fine particulates) is a

[[Page 52630]]

new indicator for particulate matter, PM2.5 is not one of

the pollutants specifically included in Merck's site-wide emissions

cap.9 Rather, Merck would be required to comply directly

with any future requirements for the control of PM2.5. At

the present time, EPA believes this is the more environmentally

protective and scientifically sound approach, since no baseline data

are available about Merck's PM2.5 emissions, methods to

measure and monitor PM2.5 are not yet widely available, and

it would be speculative to attempt to regulate PM2.5 as part

of the site-wide emissions cap. Moreover, it will likely be several

years before states have enough monitoring information available to

know whether areas are not attaining the PM2.5 standard,

and, consequently, whether and what type of PM2.5 control

strategies are needed in a given area to bring an area into attainment.

It should be noted that sulfates and nitrates are major components of

secondary fine particles, formed in the atmosphere through chemical

reactions. Therefore, the SO2 and NOX reductions

from Merck's powerhouse conversion will help to reduce fine

particulates.

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

\9\ However, Merck will be required to include emissions of

PM2.5 (as a subset of PM10) in its calculation

of PM10 emissions.

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

The proposed site-specific rule (40 CFR 52.2454(a)(2)), stated that

the rule applies in lieu of 40 CFR 52.21 for the pollutants included in

the site-wide emissions cap, as well as particulate matter. In the

final site-specific rule, EPA is adding language to ensure that it is

clear that the rule does not apply in lieu of 40 CFR 52.21 for

particulate matter specifically regulated as PM2.5.

This change makes clear that the site-specific rule replaces 40 CFR

52.21 for particulate matter and PM10, but not for

particulate matter that is specifically regulated as PM2.5.

Similar changes also will be made in the final PSD permit to ensure

that it is clear that the project does not provide alternate compliance

for particulate matter specifically regulated as PM2.5. If

in the future EPA were to promulgate standards for other forms of fine

particulates (e.g., PM1.0), Merck also would be required to

comply directly with any associated applicable requirements.

Under EPA's revision of the ozone NAAQS, ozone is not considered a

new criteria pollutant. Rather, EPA revised the existing NAAQS for

ozone to a lower and more protective standard. The regulated precursors

for ozone formation, VOC and NOX, are included in Merck's

site-wide emissions cap. Therefore, Merck must comply with any new

regulations for the control of VOC or NOX (ozone precursors)

as prescribed by Section 1.2.2 of the permit. Under these provisions,

Merck generally will have the option to reduce the site-wide total

emissions cap (for VOC regulations) or NOX subcap (for

NOX regulations), in lieu of implementing the regulation as

written. This approach was described in detail in the preamble to the

proposed rulemaking for the Merck XL project (61 FR 15313, March 31,

1997).

D. Public Participation Issues

1. Summary

Some commenters expressed concern about continuing community

involvement in the permit. Related concerns include the unlimited term

of the PSD permit, the composition of the decision-making group, and

community input into decisions involving potential increases to the

emissions levels of the permit. These issues are addressed

substantively and thoroughly in this preamble and the Response to

Comments Document.

EPA strongly supports ongoing community involvement in permit

issues associated with this XL project. Many commenters remarked on the

unprecedented level of participation this project has afforded the

community thus far. The participation of Rockingham County as a

signatory will assist in maintaining the level of community involvement

during implementation. EPA also pledges to seek out and strongly weigh

community and public interest group input and involvement where permit

modifications or reviews are being considered. Stakeholders will be

expressly included in the five-year reviews scheduled as a result of

this project, affording public input opportunities on issues outside

the scope of existing permit programs.

PSD permits are analogous to building permits, which are not

normally revocable or subject to end dates. Thus, while this project

offers Merck flexibility in the scope of the PSD permit, it does not

offer Merck flexibility in terms of duration that it would not

otherwise receive. EPA believes that the level of accountability

contained in the proposed permit and the five-year reviews offer

adequate oversight opportunity to both regulators and the community.

These five-year reviews themselves are an additional step to ensure the

protection of public health and the environment, and offer the

stakeholders a role in the implementation of the permit. EPA commits to

making any necessary technical assistance or facilitation available to

the stakeholders during the five-year review to ensure their informed

participation.

The signatories to the Final Project Agreement (EPA, U.S.

Department of the Interior/Federal Land Manager, Virginia Department of

Environmental Quality, the Rockingham County Board of Supervisors, and

Merck) generally must agree to any permit modifications that might be

considered. During negotiations, the County was put forward as a

signatory as a way of incorporating a representative vote for the

community. The County, State, U.S. Department of the Interior, and EPA,

as governmental entities, will ensure public support for any changes

that go forward. If increases in the emissions caps are contemplated,

EPA generally must amend the site-specific rule to propose changes to

the permit. Although EPA fully expects that such increases in the

emissions caps will not be necessary and therefore will not be

proposed, EPA commits that, in any such instance, it will seek out and

strongly consider the input of the community.

EPA would also like to note that, as described in Sections III.A.2,

III.A.3, and IV.C above, this rule and the PSD permit require Merck to

comply with future relevant regulatory changes or new standards that

would otherwise apply to the facility.

Community involvement is and will continue to be critical to the

success of Project XL. The Merck project was, in many ways, shaped by

the input of the stakeholder group associated with the project. For

example, Merck's original project proposal was greatly improved during

the stakeholder process by addressing many stakeholder concerns,

including a 20% decrease of the total emissions cap after the

powerhouse conversions, emissions subcaps for PM-10, SO2 and

NOX, strict compliance with all hazardous air pollutant

(HAP) requirements, modeling of non-HAP VOC emissions to ensure

protection of public health, assessment of VOC impacts in Shenandoah

National Park, and several other provisions. EPA believes that the

project as it is now reflected in the proposed PSD permit, the Final

Project Agreement and the site-specific rule will enhance the

community's opportunity for meaningful involvement in the

implementation of the Merck XL project.

2. Permit Term

EPA received numerous comments from citizens and environmental

groups supporting a limit on the term of the

[[Page 52631]]

PSD permit. Some commenters suggested that a limited permit term be

established, after which the permit could be ``affirmatively renewed''

or renegotiated within some set of preestablished guidelines. Most of

these commenters supported an initial permit term of 10-15 years, and

one environmental group suggested a five year term. Another

environmental group suggested an initial permit term reasonably

sufficient to allow Merck to recover its investment in the boiler

conversion, after which the permit could be affirmatively renewed on a

five-year basis. One environmental group maintained that the unlimited

permit term is unwise because the permit allows substantial VOC

increases and there is currently inadequate information regarding the

impacts of the VOC emission increases on human health and the

Shenandoah National Park. One commenter believes that no other XL

project has a permit with unlimited duration and a provision for veto

of any changes by the applicant, and believes that this permit would

establish an inappropriate precedent for these conditions.

Merck commented that the decision to craft the permit under PSD and

include extensive review and termination procedures (Sections 6 and 8)

was the compromise worked out among the stakeholders. Merck expressed

that, absent new, compelling information from commenters on this issue

they believe that EPA must act in good faith and decline any changes

with regard to permit expiration.

In response, EPA notes that the ``unlimited term'' of the permit is

consistent with the normal practice for PSD permits. They are permits

to construct or modify a source, and are analogous to building permits

which would not normally be revocable or have an end date. Once a

source is permitted to construct the emission units authorized by the

permit, so long as it complies with the permit's emission limitations

and operational conditions, a source generally is not required to renew

the PSD permit for those units. Under the particular circumstances

presented in the Merck project, including the innovative emissions cap-

based permit and Merck's substantial voluntary investments to achieve

significant emission reductions, EPA believes it is appropriate to

treat the entire set of changes authorized at the facility by this rule

and the PSD permit as a single major modification. Because Merck's

permit will be issued as a PSD permit, under a new site-specific PSD

rule which applies only to the Stonewall Plant, EPA believes it is

consistent with the PSD program not to establish a term limit for

Merck's permit. As a related issue, there currently are no specific

Federal regulations for modifying PSD permits. If EPA in the future

should promulgate permit modification rules that generally apply to PSD

permits, Merck's permit would be subject to those permit modification

procedures as well (Section 6 of the permit). In addition, the Merck

permit goes beyond typical PSD permits by requiring a five-year

periodic review and setting forth provisions for revising the permit.

(See Section IV.D.3.b of this preamble for a more detailed discussion

of the five-year review process). Therefore, EPA believes an unlimited

term is warranted to allow the permitted modifications to occur as

intended, subject to the safeguards in the permit.

In comparison to the opportunities for public involvement in the

typical PSD permitting process, the Merck XL project offers the public

an opportunity to be more fully informed about the environmental

activities and changes at the facility. Absent Project XL, if Merck

were to make a change at the facility that triggered a PSD permit

review, the public would only have opportunity to comment on the

specific project being permitted at that time. Further, it is difficult

to speculate if and when the Merck Stonewall Plant would trigger a

future PSD review, since it has never done so in its history. All of

Merck's existing air permits are minor NSR permits. It is possible that

Merck would have been required to undergo PSD review in the future

(e.g., for a new pharmaceutical product line); however, the existing

regulations would allow Merck to avoid PSD review if the emissions

increase was less than the significance level, if it ``netted out'' of

PSD review, or if it took a synthetic minor emissions limit. In any of

these cases, the Commonwealth of Virginia would issue a minor NSR

permit. Under the Commonwealth's minor NSR program, many types of

permit changes can be made with little or no public participation. Even

in cases where public participation is available under the minor NSR

permitting process, public comment would be open only to the particular

process being permitted. As explained above, for PSD permits as well as

minor NSR permits, there is no term limit on the permit, and the public

would not have an opportunity to comment on the facility's performance

under the permit after the permit was issued.

Without this XL project, there would be no opportunity for

stakeholders to participate in a regular five-year review of the

facility's operations, no opportunity for stakeholders to request

permit changes to be considered, and no opportunity for the community

to give consent to permit changes. By participating in the five-year

permit review, the community will be much more fully informed about,

and involved with, the facility's operations than they would under the

traditional permitting system. During development of the initial XL

project, all stakeholders learned a great deal of information about

Merck's air emissions, emission units, monitoring methods, and facility

operations. This level of information will continue to be shared during

the stakeholder discussions for the five-year permit reviews. Under the

traditional permitting process, the public would not have access to

this level of facility-wide information, because the emissions

information would be limited to the particular process undergoing

permit review. Therefore, considering the full set of public

participation opportunities under this XL project as compared to the

traditional permitting system, EPA believes that Merck's XL project

offers the public more comprehensive involvement in overseeing and

reviewing facility operations.

In response to the comment regarding the term of permits in other

XL projects, there is at least one other XL project in which a PSD

permit is expected to be issued. In the Weyerhauser XL project, the

State of Georgia plans to issue Weyerhauser a PSD permit as the

mechanism to make enforceable the emissions caps described in the XL

agreement. At this time, EPA understands that Weyerhauser's PSD permit

will not have a limited duration. With regard to a commenter's concern

about the permit term in the Merck XL project establishing precedent,

EPA does not view any XL project as setting a precedent for future

projects. Each project must be evaluated by the Agency and by

stakeholders on an independent basis, considering the unique nature of

the project and the company's full set of obligations under the

proposed XL agreement.

3. Stakeholder and Public Involvement

a. General. Several citizens and environmental groups commented

about the public participation involved in developing this proposed

project. Merck commented that the stakeholders have made significant

efforts to notify and educate the public about the project. A community

meeting was held in December 1996, two public hearings were held in

February 1997 and April 1997 (one by VADEQ and one by EPA),

[[Page 52632]]

a Merck retiree dinner was held, the Stonewall site's employees and

Community Advisory Panel were briefed several times, several newspaper

articles were published, and numerous newsletters and other documents

were prepared and distributed to neighbors, retirees, employees, the

media, and local state and federal government officials. In addition,

Merck believes that the permit reviews represent a process that is

unprecedented in air permitting in this country, and that the community

will be provided with significant oversight of Merck's permit.

From Project XL's inception, EPA has stressed that stakeholder

involvement and opportunities for public participation are critical to

a project's success. During development of the Merck XL project, the

public was given numerous opportunities for participation--far more

than under the normal permitting process. Merck initiated a number of

efforts to inform the local community about the project. EPA believes

that Merck's comment provides a good summary of the communications

outreach efforts undertaken during the development of this XL project.

At the outset of the project, Merck developed and shared with the

stakeholders a public involvement plan that included many of the

activities described in Merck's comment above. This set of public

involvement activities is fully consistent with the XL guidelines in

place at the time of Merck's project development.

An environmental group commented that the stakeholder process for

five-year permit review should follow EPA's April 23, 1997 XL

guidelines in identifying and selecting direct participants and

commenters. The commenter believes that ``direct stakeholders'' are

those who sign off on the project and have a vote in the five-year

review and potential permit changes. The commenter believes that the

direct stakeholder group is not broad enough, because the commenter

believes that EPA's XL guidance provides that additional stakeholders

should be involved in the XL project development stage. Given that the

Merck XL proposal has unlimited duration and a number of key issues

were left to the five-year review process, the commenter recommends

that the stakeholder process for periodic review should be equally as

broad as the stakeholder process recommended by EPA for project

development. The commenter requests EPA to ensure that the five-year

review process meets the following [excerpt from 62 FR 19878-19879,

April 23, 1997]: ``The project sponsor should make special efforts to

recruit potential direct participants and commentors from among

economically disadvantaged stakeholders and among stakeholders most

directly affected by the environmental and health impacts of the

project; * * * who have specific interest or expertise in the issues

addressed in the project from among the national environmental justice

communities and the industry segment of which the facility is a part;

and * * * from among participating facilities' non-managerial

employees.'' The commenter believes that the proposed make-up of the

stakeholder group for permit review does not adequately reflect

interest from these groups. In addition, a company located in

Rockingham County, Virginia commented that it and other industries in

the area should be considered significant stakeholders to the outcome

and implementation of the project.

Merck commented that it sought to involve parties with a direct and

specific stake in the project from the beginning. Merck maintained that

a wide variety of interests was represented and all contributed to the

innovative proposed permit. Based on the success of this process, Merck

asserts that the proposed permit provides for these stakeholders to

have a continuing opportunity for direct and valued input during

operation under the permit as well. Merck believes that, particularly

for the local community and regional public interest groups, these

opportunities far exceed anything which they would be afforded under

the current regulatory system. With regard to the April 23, 1997 XL

notice's guidelines of three classes of stakeholders (general public,

commentors, direct participants), Merck stated that it has considered

its community representatives as ``direct participants'' since the

project's inception, although it states that under this guidance they

could have been considered ``general public'' with limited input. Merck

points out that the XL guidance also states that the FPA should

identify how to make information about the project, including

performance data, available to stakeholders in an easily understandable

form. Merck stated that it has committed to share with stakeholders and

other interested parties an annual report. Merck further stated that it

has committed to including all direct participant stakeholders in

periodic evaluations, even though the guidelines indicate this would

not be required. Merck believes that the permit's stakeholder process

for five-year permit reviews is far beyond the level of stakeholder

involvement suggested in EPA guidance, and certainly beyond what is

currently provided to the public in any other environmental permitting

forum.

EPA agrees that the stakeholder group as defined in the Merck

project meets the Agency's guidance regarding direct participant

stakeholders. EPA believes that the stakeholder group, comprised of

Merck, EPA, VADEQ, U.S. Department of the Interior, community

representatives and a public interest group, represents a fair balance

of interests. The excerpt from the April 23, 1997 XL notice submitted

by one commenter pertains to the types of interests that should be

represented by both direct participant stakeholders and ``commenters''.

In the April 23, 1997 notice, ``commenters'' are described as those

individuals or groups that have an interest in the project, but not the

desire to participate as intensively in its development. EPA believes

that the Merck project is consistent with the guidance by including

direct participants in the makeup of the stakeholder group for five-

year permit reviews. However, EPA does not agree that it is required

that the stakeholder group must include ``commenters'' as described in

the April 23, 1997 notice. EPA encourages the stakeholder group to

establish a mechanism for communicating information about issues being

discussed in the five-year reviews at appropriate points during the

process, and to consider the input from ``commenters'', such as area

industries or other environmental organizations.

A number of citizens and environmental groups commented that there

should be more public involvement in the permit review process. A few

citizens believe the proposed permit minimizes public participation in

the permit review process, and that full public participation is

supposed to be a major component of the XL program. Other citizens

commented favorably about the opportunity for direct involvement of the

local community in the oversight of the project.

A commenter maintained that the community representatives selected

by the Rockingham County Board of Supervisors will not really have an

effective voice in reviews and other decisions because their concerns

can be vetoed by Merck or other signatories. A citizen commented that

permit revisions should be decided by the majority, but not all of the

project signatories, which might ensure that corrective adjustments to

the permit are made. The commenter also suggested that a public hearing

be held by VADEQ midway through each five-year review.

[[Page 52633]]

EPA disagrees that this project minimizes public participation in

the permitting process. On the contrary, the permit provides for much

greater public involvement than other permits of its type. This permit

provides unique opportunities for public involvement through the

stakeholder process and periodic permit reviews. In the PSD program,

once a PSD permit is issued, normally there is no opportunity for

future public involvement in the permit's implementation. The Merck PSD

permit will provide a unique opportunity for strong public involvement

in reviewing the facility's operations under the permit. Further, since

there currently are no specific Federal regulations governing PSD

permit revisions, typically EPA does not initiate PSD permit changes

without consent of the permittee. PSD permit revisions usually are made

at the request of the source, with consent of the source and the

permitting authority. Accordingly, the EPA believes that providing an

explicit veto for Merck, in conjunction with the extraordinary level of

stakeholder involvement in the project, provides an appropriate level

of assurance to Merck that the agreements on which this rule and permit

are based upon will generally continue in their current form, subject

to specific terms of the rule and permit, and to consensus-based permit

changes.

Under Merck's PSD permit, Rockingham County and every other

signatory will have an effective voice in the permit review process

because changes to the permit generally must be made upon full consent

of all the signatories. This means that there may be issues that

Rockingham County, or any other one signatory, does not support and can

thus ``block'' a change to the permit by not giving consent to the

change. Rather than being viewed as a ``veto'', this process should be

viewed as ensuring that a permit change is proposed only when there has

been full discussion and consideration of the impacts of the change.

Allowing permit changes to be decided by a majority of the signatories

not only would erode Merck's ability to prevent changes that may be

unworkable for its facility, but also would compromise the ability of

any other signatory to prevent permit changes that it does not support.

All stakeholders have an opportunity to be fully involved in these

discussions and to raise issues, bring forth technical information, and

offer proposed resolutions for consideration. This process is more

likely to result in proposed permit changes that are the outcome of

consensus among the signatories. It is also important to note that

Merck has no ability to ``veto'' any future enforcement actions or

regulations which may impose additional requirements on the facility

outside of the PSD permit.

The permit modification procedures in Merck's site-specific PSD

rule (40 CFR 52.2454(n)) require the permitting authority to provide an

opportunity for a public hearing for all permit modifications except

those that meet the criteria for an administrative permit amendment (40

CFR 52.2454(n)(2)). Thus, if the signatories agree to any permit

changes, the VADEQ must provide for public participation, including an

opportunity for a public hearing, for those permit changes that do not

qualify as administrative modifications. Any permit modification could

also be appealed by residents or others with legal standing. EPA does

not agree that it is necessary to provide for a public hearing during

the five-year review process itself, since an opportunity for a public

hearing will be provided if non-administrative permit modifications are

proposed. EPA believes that public views can be effectively represented

by the designated stakeholders during the process of developing any

permit modifications. EPA encourages the stakeholder group to consider

holding public meetings, similar to the one held during the initial

project development, to inform the broader public of anticipated

changes under consideration by signatories during the five-year review

process. Other forms of communication (e.g., newsletters) to the public

may be useful in communicating the issues under discussion and

anticipated permit changes. EPA intends to continue to suggest

effective forms of communication with the public during each five-year

review and to participate in these activities along with the

stakeholder group.

A citizen commented that the list of permit changes which the

stakeholders can consider in the five-year reviews should be broadened

to include, for example, permit termination, modification of caps,

change in signatories, change in permit modification procedures,

changes in significance levels, and others.

Section 6.1.1. lists the most fundamental types of permit changes

anticipated by the stakeholders during the development of the project.

In addition, these periodic review criteria will be reviewed by the

stakeholders at each five-year review. EPA does not agree that it is

necessary to add additional review criteria at this time, since it will

be more effective to consider new criteria, if necessary, at the time

of each five-year review. The permit also provides that any stakeholder

may raise issues about the PSD permit at any time, as needed.

b. Project signatory consent to permit changes during five-year

reviews. In the notice of proposed rulemaking, EPA solicited comment on

the approach to stakeholder involvement during the implementation of

the Merck XL project. See 62 FR 15307 (March 31, 1997). EPA received a

number of comments regarding the stakeholder process for reviewing the

permit every five-years. Particularly, numerous comments were received

on the issue of whether the consent of all stakeholders, or only the

project signatories, should be required to make proposed permit changes

(i.e., to recommend that the permitting authority process a permit

modification). The permit generally requires consent of all project

signatories prior to making a proposed permit change. Project

signatories are defined as EPA, VADEQ, Merck, U.S. Department of the

Interior Federal Land Manager, and the County of Rockingham. The permit

also provides that additional stakeholders have an opportunity to

directly participate in the permit review process, but their individual

consent is not required for permit changes. These additional

stakeholders include up to three community representatives and a

regional public interest group. If the project signatories agree to

permit changes, then the permitting authority may process a permit

modification according to the requisite procedures (40 CFR 52.2454 (m)

and (n)). These permit modification procedures require public

participation, including a 30-day public comment period and opportunity

for a public hearing, for any permit change not defined as an

administrative modification.

EPA received a number of comments from citizens and environmental

groups that the consent of the three community representatives, in

addition to Rockingham County's consent, and the public interest group

should also be required prior to making a permit change. Alternatively,

Merck, citizens, industry representatives, and a state environmental

agency supported the process established in the proposed permit, and

that the County's consent is the appropriate representation of concerns

of the community as a whole. The comments on this issue are summarized

below.

One of the community representatives on the Merck XL stakeholder

group supported that the three community representatives who are

appointed to

[[Page 52634]]

the five-year periodic review should be allowed to come to consensus

and then cast one single vote along with the signatories regarding

proposed changes to the PSD permit. This commenter believes that the

community at large should be directly involved in any permit changes,

and that the interests of the County government and the local community

at large are not necessarily the same and could differ vastly on

proposed changes to the PSD permit. The commenter maintains that

disallowing the three community representatives one single vote in this

process reduces their input to a mere advisory role. This commenter

believes that the local community at large looks to their community

representatives and EPA for representation and protection. This

community representative submitted a petition signed by about 240

people, which read ``We the following residents of Rockingham County

and Harrisonburg, do request with regard to the Merck XL Air Quality

Project, Elkton, VA, that the three community representatives appointed

to the project's five-year reviews be allowed to cast one vote along

with the voting signatories to the project on proposed changes to the

Prevention of Significant Deterioration (PSD) permit which replaces all

other air quality permits.''

An environmental group commented that the permit should provide for

``stakeholder'' consensus on permit changes, not just ``signatory''

consensus, because of the concern that the state, federal agencies, and

Rockingham County could agree with Merck to raise the emissions cap,

and the community representatives or public interest group would have

no real say in that decision. The community and public interest group

want to be assured that they are getting permanent reductions in

emissions, and are concerned that the emissions caps could be increased

in the future. This commenter believes that most of the permit was

negotiated with the understanding that the community representatives,

including, potentially, a regional public interest group, would have to

agree to any permit changes. The commenter objects to the permit

language being changed to provide community representatives and public

interest group as ``stakeholders'' only. The commenter fully supports

Rockingham County as a signatory, but believes the community

representatives living downwind of the plant and the public interest

group provide a perspective different from, and independent of, County

concerns such as jobs and tax base.

A community representative on the Merck XL stakeholder group

commented that there should be ground rules set up for the five-year

reviews, and perhaps a neutral facilitator. This commenter and an

environmental group also recommended that there should be funds set

aside to provide technical assistance for the community at the five-

year reviews, so that the community has a fuller understanding of the

impacts of any permit changes under consideration.

A number of citizens and environmental groups commented that Merck

should not have a ``veto'' over suggested permit changes. Some

commenters expressed concern that, because full consent of the project

signatories is needed for proposed permit changes, Merck can ``veto''

changes and ignore evidence of air quality and resource degradation in

Shenandoah National Park. One commenter suggested that the stakeholder

agencies should be responsible for determining the need for, and extent

of, permit revisions. Absent that, the commenter believes that a

funded, organized, strong public interest presence be included among

the signatories.

EPA also received a number of comments supporting the roles of

signatories and stakeholders in the five-year review process as

proposed in the permit. Two citizens commented that they support having

an elected member from the Rockingham County Board of Supervisors

designated to represent the community. One of these commenters believes

it is wrong for an individual citizen of the community to have a vote

for approval of permit changes. The commenter states, ``I could ask why

I do not get the vote?'' The commenter believes the elected officials

will adequately represent him, and if not he has a recourse at the

polls. With a community representative on the stakeholder group, he

does not.

Several commenters, including a state environmental agency,

industry association, a company that participated in another XL

project, and Merck, commented that the local community interests, in

particular, are afforded an unprecedented opportunity to participate in

and influence the project. Many of these commenters expressed that the

Merck XL project goes well beyond the role provided for community

interests in the current regulatory system. These commenters strongly

endorse having the community's voice on the stakeholder team through

the local government, because it ensures representation of the

interests of the whole community. Merck commented that the permit's

approach establishes an extremely important balance in community

representation: it ensures that vocal and interested community members

have a voice, and that the interests of the entire community are

considered. Merck believes that it is appropriate that individuals who

may be particularly concerned with the facility's operations, or who

have specific expertise or input on a relevant issue, be provided with

a full opportunity to voice their opinion. However, Merck maintains

that meaningful community involvement must provide some assurance that

the interests of the community as a whole are represented.

Two commenters maintained that it is an unusual suggestion that the

Rockingham County Board of Supervisors does not represent the interests

and well-being of County residents. These commenters assert that the

local government is directly accountable to the residents that they

represent; if the County officials fail to represent the community, the

voters have a responsibility to remove those individuals and elect

representatives that do. The commenters believe that a County

appointee, in consultation with the three other community stakeholders,

will be well equipped to voice the authentic views of the community.

Merck believes that granting two community ``votes'' on the stakeholder

group would not be providing a more open process, but rather, a more

closed process that could allow the opinion of a few vocal individuals

to prevail over the vital interests of the community at large.

Several commenters raised the concern that individuals representing

only their own interests may adopt extreme positions which are not

truly representative of community sentiment. Commenters stated that

having a team of community representatives led by a local government

official provides an appropriate measure of accountability and

stability in the process.

Commenters believe that this approach will help assure that

individuals who do not truly reflect the interests of the community as

a whole are not granted a veto over a permit change that all other

stakeholders otherwise find to be beneficial. Several commenters

maintain that this system embodies the basic principles of our

governmental system--accountable, elected representatives are charged

with representing the peoples views on matters of public policy. A

company that participated in Project XL contends that the function of

community advisory groups must not be misinterpreted to

[[Page 52635]]

duplicate those of government. This commenter believes that stakeholder

panels are an excellent means of getting early and meaningful input

into environmental decisions, but, as both a practical and legal

matter, they cannot assume the decisional role of government.

Merck and another company commented that the stakeholder process

infuses a certain amount of risk for Merck, and that this additional

risk is an important factor to consider when evaluating the adequacy of

community involvement in future permit discussions. Merck stated that

it could not accept a permit that would threaten the future viability

of the plant. Merck believes that the permit was carefully crafted to

ensure that it would provide enhanced community oversight, but not

subject the plant to unacceptable control by outside parties. Merck

commented that the proposed permit is crafted to reflect the process

that was used in the formation of the project--each represented group

is granted one ``vote'' in future permit reviews. Merck stated that

none of the parties objected to this approach; all agreed that it was

sensible that each party would reach a single position and bring that

position to the stakeholder group. Merck believes it is unclear why

this approach is now not acceptable.

Merck commented that the petition (referenced in a previous comment

above) submitted to EPA does not provide any insights to what those who

signed would be willing to accept as an alternative to two community

votes, nor does it elucidate why they question their representation by

Rockingham County and their ability to influence the County's views in

future permit discussions. Merck believes that the County has already

demonstrated the seriousness with which it accepts this charge to

represent the community in the project negotiations. Merck stated that,

despite an accelerated schedule to finish its review, in December 1996

the County insisted that it needed additional time for its independent

technical consultant to analyze the draft permit and agreement before

providing its consent. Merck believes that EPA should have every

expectation that the County will continue to take its duty to represent

community interests seriously.

Merck commented that a public interest group representative should

not be added as a signatory. The permit specifies that a representative

from a regional public interest group be included as a stakeholder,

although not with the ability to vote on permit changes. Merck believes

that this is a unique opportunity for such groups which far exceeds

that available to them under existing environmental regulations. Merck

claimed that granting this representative with the same oversight as

other signatories would be inappropriate and a serious compromise to

the future viability of the Stonewall plant. Merck believes that a

public interest group representative is not held accountable in any

meaningful way to the public for his/her views. Merck maintains that

the permit as crafted provides very significant input for public

interest groups while assuring that only parties that have public

accountability are granted oversight for permit changes.

Finally, Merck urged EPA to maintain the stakeholder provisions of

the permit as proposed, because to include a second ``vote'' for the

three community representatives would:

1. Endorse the accusation that the Rockingham County Board of

Supervisors, despite being elected by the community, does not represent

the community's interests.

2. Question the ability of EPA, DEQ, and NPS to act on legitimate

environmental concerns for the protection of the public interest at

large.

3. Indicate that the stakeholder process for the formation of the

project is inadequate for project implementation.

4. Shatter the important balance that the County would bring as the

lead representative of the entire community.

5. Contradict the XL guidance (April 23, 1997 Federal Register

notice) by setting a standard for public involvement far above what

could be required for future XL projects.

6. Agree that it is reasonable to have a process that would allow

the opinion of a few vocal individuals to prevail over the interests of

the community at large.

7. Narrow rather than broaden the representation of community

interests on the project.

8. Suggest that the project stakeholders would not continue acting

in good faith for future permit reviews.

9. Imply that Rockingham County's efforts to obtain independent

review and advice on the agreement fell short of what is necessary to

properly protect the community's interests; and

10. Threaten the future of a project that would otherwise provide

the community with unprecedented oversight of Merck's air permit, that

would significantly reduce actual emissions of pollutants of particular

concern to the region, that would provide an ongoing incentive for the

facility to minimize emissions, and that, as EPA, VADEQ, National Park

Service and the community have acknowledged, would provide superior

environmental benefit.

In response, EPA believes that the permit represents a fair balance

of interests. The permit significantly enhances the involvement of the

community and other stakeholders in overseeing the environmental

impacts of the Merck Stonewall Plant. Stakeholders will have an

unprecedented opportunity to participate in the ongoing evaluation of

the project and to recommend any necessary changes to the project. The

permit provides that the stakeholders review and evaluate the project

at least every five-years. If the project signatories (i.e.,

signatories to the Final Project Agreement, namely EPA, VADEQ, Merck,

U.S. Department of the Interior Federal Land Manager, and Rockingham

County Board of Supervisors) give full consent to any necessary permit

changes, the permitting authority may process a permit modification

according to the requisite permit modification procedures (see 40 CFR

52.2454(n)). The permit identifies numerous issues that may be

considered by the project stakeholders during each five-year review.

Stakeholders also have the opportunity to raise issues of concern at

any time for discussion by the stakeholder group.

The permit defines ``project stakeholders'' as the project

signatories to the FPA plus other parties as follows: (1) Up to three

other community representatives shall be included as nominated by the

Rockingham County Board of Supervisors, and agreed to by full consent

of the project signatories to the FPA. Community representatives are

defined as local government and/or community residents with an ongoing

stake in the project; and (2) Up to one representative from a regional

public interest group shall be included as nominated by any project

signatory and agreed to by full consent of the project signatories.

This group of stakeholders will convene every five years to review

whether changes to the permit are necessary. As discussed above, the

permit establishes that full consent from the project signatories, and

not each member of the stakeholder group, is necessary before permit

changes can be made. This stakeholder process for five-year reviews is

consistent with the process used in the development of the proposed FPA

and draft permit. The County of Rockingham is the signatory to the FPA

(i.e., a project signatory) representing community interests. The three

additional members of the community team (two neighbors of the

[[Page 52636]]

Merck Stonewall Plant and the Town Manager of Elkton) also actively

participated in the stakeholder group. The County was designated as a

project signatory at the request of the community team in order to

insure long-term representation and continuity of community

interests.10 This model of stakeholder involvement provided

all stakeholders with full information and ability to shape the

development of the project.

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

\10\ See July 1, 1996 letter from the Merck XL community

representatives to the County Administrator and Members of the

Rockingham County Board of Supervisors (contained in the docket).

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

EPA supports the provisions set forth in the proposed permit that

require the consent of signatories only, and not the full stakeholder

group, for proposed permit changes during the five-year review process.

EPA agrees with several commenters that it is most appropriate that the

representative of the Rockingham County Board of Supervisors will

represent the views of the whole community, taking into account the

interests and well-being of the County constituents. The role of the

three community representative stakeholders also is important for

identifying specific concerns, questions, and information that can

influence the stakeholder discussions. EPA expects that Rockingham

County's decisions about permit changes will substantially reflect the

input and views of the three community representatives, as well as the

interests of the community at large. Further, EPA believes that the

five-year review process offers a role for a public interest group that

is greatly enhanced as compared to the normal permitting process. The

permit is designed such that all non-signatory stakeholders will be

fully involved in the deliberation of all permit issues, as in the

development of the Merck XL project. During the development of the

Merck XL project, all stakeholders, as well as several environmental

groups that were not part of the stakeholder group, provided valuable

comments on the draft permit. These comments were fully considered by

the project signatories and helped to shape the project. EPA expects

that the same interaction among stakeholders will occur during the

five-year permit reviews, and that the project signatories will fully

consider concerns and issues raised by all the stakeholders before

reaching decisions on permit changes.

EPA does not believe that the permit's process for stakeholder

involvement in any way diminishes the role of the non-governmental

representatives. Throughout Project XL, EPA has made clear that it

places a high degree of importance on public support and will give the

views of the public significant weight in deciding whether to proceed

with a project. EPA will take the same approach on making decisions

during project implementation. EPA will make every effort to ensure

that the concerns of the community and the public interest group

representatives are fully explored and addressed by the signatories.

Prior to making a decision about whether to give consent to proposed

permit changes, EPA intends to fully consider any outstanding concerns

raised by the community representatives or the public interest group,

and encourage other signatories to do the same.

This XL project is composed of an experimental, innovative

emissions cap-based PSD rule and permit, which fully authorize

modifications at the facility to occur without changes to the permit,

so long as the emissions caps and other permit terms are met. Most

future ``modifications'' thus will not require any permit changes and,

therefore, will not need any agreement among the signatories; in these

instances, any right of the stakeholders to vote on or veto changes

will not be relevant. The signatory consensus process is relevant only

for other types of changes at the facility necessitating changes to the

permit. Regarding these latter kinds of permit changes (i.e., those not

associated with a ``modification'') the EPA notes that the permit will

continue to be governed by the site-specific rule (e.g., the caps must

be consistent, or lower than, recent actual emissions, as discussed

elsewhere in this document), and any resulting permit modification will

occur only after stakeholder input during the five-year review process

and will be judicially reviewable. As explained above, the EPA believes

the level of stakeholder involvement in the Merck project is

unprecedented in its scope and detail.

It is important to realize that any permit changes agreed to by the

signatories must be processed by the permitting authority according to

the required permit modification procedures. For the vast majority of

changes (i.e., except those changes defined as administrative), the

permitting authority is required to provide 30 days of public comment

and an opportunity for public hearing. See 40 CFR 52.2454 (m) and (n).

Thus, any member of the public will have a full opportunity to comment

on any non-administrative changes agreed to by the signatories. It is

the permitting authority's responsibility to fully evaluate and respond

to any public comments received on proposed permit changes. If the

permitting authority determines that there is an inadequate basis for a

proposed permit change, based on additional information received

through public comments, the permitting authority may decide not to go

forward with a particular permit change. This would be the permitting

authority's decision to make, independent of the signatories. In this

circumstance, the signatories could decide to reevaluate the proposed

permit change and attempt to address the public comments and could

request the permitting authority to re-propose the permit change. In

addition, nothing in this rulemaking or the permit would limit a

citizen's rights to judicial review of any final action taken by the

permitting authority.

EPA believes that stakeholders, and other members of the public,

are assured substantial rights in the event a permit modification is

considered. Any significant modification would have to undergo public

notice and comment, and would be subject to judicial review. Moreover,

any decision to approve a modification would have to be supported by an

administrative record, and stakeholders will have the opportunity, even

prior to the formal notice and comment process, to submit information

that might indicate that a modification was unwarranted. EPA has

consistently made clear that in Project XL it is highly unlikely to

take an action that does not have broad stakeholder support. In light

of these protections, EPA does not believe it is necessary for the non-

signatory stakeholders to have a formal veto. EPA believes that what is

more important than vetoing changes proposed by others is the ability

of the stakeholders and the public to propose changes when they believe

the existing permit is not satisfactory. EPA believes the five-year

review process will provide such an opportunity. Outside Project XL, no

such opportunity would typically exist under a PSD permit.

Based on the public comments, EPA understands that one of the

significant concerns of environmental groups and citizens is the

possibility that the emissions caps will be raised in the future. The

site-specific rule requires emissions caps to be established based on

the site's actual emissions during a time period, within five years of

permit issuance, which represents normal source operation, or a

different time period if it is more representative of normal source

operation. Reductions to the initial caps are required after the

powerhouse conversion. Thus, the emissions caps generally could not be

raised above these levels under this rule. The site-specific rule would

need

[[Page 52637]]

to be revised in the future to authorize any increase in the emissions

caps that is not already provided for in the rule or permit. For

example, the permit provides that the emission caps may be increased in

the following circumstances, which are primarily technical corrections:

(1) The emissions caps may be adjusted to account for changes in

emission factors which require a recalculation of the emissions

baseline (i.e., to ensure an ``apples to apples'' comparison of current

actual emissions to the emissions cap); and (2) the PM10

emissions cap may be increased to account for the quantity of

condensable PM10 from the new powerhouse. These changes in

emissions caps would not require a revision to the site-specific rule,

since they are already authorized by the rule and proposed permit.

However, if the signatories contemplate increases to the emissions caps

for other reasons in the future, the site-specific rule would first

have to be revised to authorize the cap increase. As part of the docket

for such a rulemaking change, EPA would intend to ensure that an

appropriate technical demonstration is conducted which justifies both

the need for and the environmental impacts of the proposed emissions

increases. EPA notes that any further decreases to the emissions caps

(other than those already provided for in the permit) would require a

revision of the permit, but not a revision of the site-specific rule.

EPA recognizes its responsibility to ensure meaningful

participation in the stakeholder process, and will make every effort to

accommodate the needs of stakeholders during the five-year permit

reviews. EPA will make available its own technical expertise to respond

to questions and concerns raised by the stakeholders. EPA also expects

Merck to continue to provide assistance in understanding and evaluating

technical issues. During the development of the Merck XL project, Merck

made several technical presentations to the stakeholder group about

various aspects of the project, including emissions calculation

methodologies and how certain regulatory requirements affect the

facility. Merck also hired a technical consultant to answer the

stakeholders' questions about the impacts of potential VOC emissions on

ozone formation. EPA expects that, as needed, Merck will continue to

provide pertinent technical information to the stakeholders during the

five-year review periods. Further, EPA hopes that Rockingham County

will continue to seek technical advice and assistance during the five-

year reviews, as it did during the initial project development.

Rockingham County employed a consultant from James Madison University

to review the proposed XL project and make recommendations to the

County. A County official commented that the consultant had a very good

understanding of the process and the documentation provided. The County

stated that the consultant recommended that the County support the

project. The County's consultation with technical advisors can be a

very effective way of addressing the technical assistance needs

identified by the community.

EPA offered guidance on its ability to support technical assistance

in a Federal Register Notice on Modifications to Project XL. See 62 FR

19872 (April 23, 1997). EPA recognizes that, in some cases, there will

be a need for the Agency to offer some additional support for technical

assistance to the ``direct participant'' stakeholder

group.11 The Agency has committed to provide up to $25,000

per project over the next few years in order to assure that necessary

technical assistance is available to support meaningful stakeholder

involvement. As EPA explained in the April 23, 1997 Federal Register

notice, EPA plans to make these funds available on a task-specific

basis and funds will not be in the form of grants to stakeholder

groups. EPA has issued a solicitation for proposals from not-for-profit

and academic institutions to manage and operate a technical assistance

program for Project XL stakeholders. The April 23, 1997 Federal

Register notice explains additional qualifications on the use of this

technical assistance. For example, technical assistance funds are not

available to address strictly individual needs, but rather, needs for

technical assistance must be identified and requested by the direct

participant stakeholder group as a whole. For the Merck XL project, EPA

fully intends to pursue making available similar resources at the time

of the five-year periodic reviews to provide the technical assistance

necessary to ensure a meaningful stakeholder process.

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

\11\ In the April 23, 1997 Federal Register notice, ``direct

participants'' are described as those stakeholder participants who

work intensively with project sponsors during project development to

build a project from the ground up.

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

EPA agrees that the stakeholder process for five-year permit

reviews could be enhanced by the use of a neutral facilitator and

establishment of ground rules. However, EPA believes that these process

decisions should be made by the entire stakeholder group at the outset

of each five-year review. At the outset of the permit review process,

EPA encourages the Merck XL stakeholder group to discuss the need for a

neutral facilitator, and to establish a set of ground rules designed to

guide the process and help ensure common expectations.

V. Administrative Requirements

A. Effective Date

Pursuant to 5 U.S.C. 553(d)(3) and 42 U.S.C. 6930(b)(3), EPA finds

that good cause exists to make this rule effective immediately. The

Merck & Co., Inc. Stonewall Plant is the only regulated entity affected

by this rule. Merck has full notice of this site-specific rule, and is

prepared to comply immediately with the permit to be issued

expeditiously under the rule. Although EPA expects that the permit will

not be issued for at least 30 days, an immediate effective date will

allow the permitting process to proceed without delay.

B. Executive Order 12866

Because this rule only affects one facility, it is not a rule of

general applicability and therefore not subject to OMB review under

Executive Order 12866. In addition, OMB has agreed that reviews of

site-specific rules under Project XL are not necessary.

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 proposed rule would not have a significant impact

on a substantial number of small entities because it only affects one

source, the Merck Stonewall Plant, which 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.

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 the Office of Management and Budget (OMB) for review in

compliance with the Paperwork Reduction Act, 44 U.S.C. 3501 et seq.

[[Page 52638]]

E. Unfunded Mandates Reform Act

Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), P.L.

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 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.

As noted above, this rule is limited to Merck's facility in Elkton,

Virginia. 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.

60, 264 and 265 of chapter I of title 40 of the Code of Federal

Regulations are amended as follows:

PART 52--APPROVAL AND PROMULGATION OF IMPLEMENTATION PLANS

1. The authority citation for part 52 continues to read as follows:

Authority: 42 U.S.C. 7401-7671q.

2. Subpart VV is amended by adding a new Sec. 52.2454 to read as

follows:

Sec. 52.2454 Prevention of significant deterioration of air quality

for Merck & Co., Inc.'s Stonewall Plant in Elkton, VA.

(a) Applicability. (1) This section applies only to the

pharmaceutical manufacturing facility, commonly referred to as the

Stonewall Plant, located at Route 340 South, in Elkton, Virginia

(``site'').

(2) This section sets forth the prevention of significant

deterioration of air quality preconstruction review requirements for

the following pollutants only: carbon monoxide, nitrogen oxides, ozone

(using volatile organic compounds as surrogate), particulate matter

with an aerodynamic diameter less than 10 microns (PM10),

and sulfur dioxide. This section applies in lieu of Sec. 52.21 for the

pollutants identified in this paragraph as well as particulate matter,

but not for particulate matter with an aerodynamic diameter less than

or equal to a nominal 2.5 microns (PM2.5) regulated as

PM2.5; however, the preconstruction review requirements of

Sec. 52.21, or other preconstruction review requirements that the

Administrator approves as part of the plan, shall remain in effect for

any pollutant which is not specifically identified in this paragraph

and is subject to regulation under the Act.

(b) Definitions. For the purposes of this section:

12-month rolling total for an individual pollutant or the total

criteria pollutants, as specified in paragraph (d) of this section, is

calculated on a monthly basis as the sum of all actual emissions of the

respective pollutant(s) from the previous 12 months.

Act means the Clean Air Act, as amended, 42 U.S.C. 7401, et seq.

Completion of the powerhouse conversion means the date upon which

the new boilers, installed pursuant to paragraph (g) of this section,

are operational. This determination shall be made by the site based on

the boiler manufacturer's installation, startup and shakedown

specifications.

Permitting authority means either of the following:

(1) The Administrator, in the case of an EPA-implemented program;

or

(2) The State air pollution control agency, or other agency

delegated by the Administrator, pursuant to paragraph (o) of this

section, to carry out this permit program.

Process unit means:

(1) Manufacturing equipment assembled to produce a single

intermediate or final product; and

(2) Any combustion device.

Responsible official means:

(1) The president, secretary, treasurer, or vice-president of the

business entity in charge of a principal business function, or any

other person who performs similar policy or decision-making functions

for the business entity; or

(2) A duly authorized representative of such business entity if the

representative is responsible for the overall operation of one or more

manufacturing, production, or operating facilities applying for or

subject to a permit and either:

(i) The facilities employ more than 250 persons or have gross

annual sales or expenditures exceeding $25 million (in second quarter

1980 dollars); or

(ii) The authority to sign documents has been assigned or delegated

to such representative in accordance with procedures of the business

entity.

Site means the contiguous property at Route 340 South, Elkton,

Virginia, under common control by Merck & Co., Inc., and its successors

in ownership, known as the Stonewall site.

(c) Authority to issue permit. The permitting authority may issue

to the site a permit which complies with the requirements of paragraphs

(d) through (n) of this section. The Administrator may delegate, in

whole or in part, pursuant to paragraph (o) of this section, the

authority to administer the requirements of this section to a State air

pollution control agency, or other agency authorized by the

Administrator.

(d) Site-wide emissions caps. The permit shall establish site-wide

emissions caps as provided in this paragraph.

(1) Initial site-wide emissions caps. The initial site-wide

emissions caps shall be based on the site's actual emissions during a

time period, within

[[Page 52639]]

five years of the date of permit issuance, which represents normal site

operation. The permitting authority may allow the use of a different

time period upon a determination that it is more representative of

normal source operation. Actual site-wide emissions shall be calculated

using the actual operating hours, production rates, and types of

materials processed, stored, or combusted during the selected time

period.

(i) Total criteria pollutant emissions cap. The permit shall

establish a total criteria pollutant emissions cap (total emissions

cap). The criteria pollutants included in the total emissions cap are

the following: carbon monoxide, nitrogen oxides, ozone (using volatile

organic compounds as surrogate), particulate matter with an aerodynamic

diameter less than 10 microns, and sulfur dioxide.

(ii) Individual pollutant caps. The permit shall establish

individual pollutant caps for sulfur dioxide, nitrogen oxides and

PM10.

(2) Adjustments to the site-wide emissions caps. (i) The permit

shall require that upon completion of the powerhouse conversion, the

site shall reduce the site-wide emissions caps as follows:

(A) The total emissions cap shall be reduced by 20 percent from the

initial site-wide emissions cap established pursuant to paragraph

(d)(1)(i) of this section.

(B) The sulfur dioxide cap shall be reduced by 25 percent from the

initial site-wide emissions cap established pursuant to paragraph

(d)(1)(ii) of this section.

(C) The nitrogen oxide cap shall be reduced by 10 percent from the

initial site-wide emissions cap established pursuant to paragraph

(d)(1)(ii) of this section.

(ii) The permit may specify other reasons for adjustment of the

site-wide emissions caps.

(e) Operating under the site-wide emissions caps. (1) The permit

shall require that the site's actual emissions of criteria pollutants

shall not exceed the total emissions cap established pursuant to

paragraph (d) of this section.

(2) The permit shall require that the site's actual emissions of

sulfur dioxide, nitrogen oxides and PM10 shall not exceed

the respective individual pollutant cap established pursuant to

paragraph (d) of this section.

(3) Compliance with the total emissions cap and individual

pollutant caps shall be determined by comparing the respective cap to

the 12-month rolling total for that cap. Compliance with the total

emissions cap and individual pollutant caps shall be determined within

one month of the end of each month based on the prior 12 months. The

permit shall set forth the emission calculation techniques which the

site shall use to calculate site-wide actual criteria pollutant

emissions.

(4) Installation of controls for significant modifications and

significant new installations. (i) This paragraph applies to

significant modifications and significant new installations.

Significant modifications for the purposes of this section are defined

as changes to an existing process unit that result in an increase of

the potential emissions of the process unit, after consideration of

existing controls, of more than the significance levels listed in

paragraph (e)(4)(ii) of this section. Significant new installations for

the purposes of this section are defined as new process units with

potential emissions before controls that exceed the significance levels

listed in paragraph (e)(4)(ii) of this section. For purposes of this

section, potential emissions means process unit point source emissions

that would be generated by the process unit operating at its maximum

capacity.

(ii) The significance levels for determining significant

modifications and significant new installations are: 100 tons per year

of carbon monoxide; 40 tons per year of nitrogen oxides; 40 tons per

year of sulfur dioxide; 40 tons per year of volatile organic compounds;

and 15 tons per year of PM10.

(iii) For any significant modification or significant new

installation, the permit shall require that the site install, at the

process unit, emission controls, pollution prevention or other

technology that represents good environmental engineering practice in

the pharmaceutical or batch processing industry, based on the emission

characteristics (such as flow, variability, pollutant properties) of

the process unit.

(f) Operation of control equipment. The permit shall require that

the site shall continue to operate the emissions control equipment that

was previously subject to permit requirements at the time of issuance

of a permit pursuant to this section. This equipment shall be operated

in a manner which minimizes emissions, considering the technical and

physical operational aspects of the equipment and associated processes.

This operation shall include an operation and maintenance program based

on manufacturers' specifications and good engineering practice.

(g) Powerhouse conversion. The permit shall require that the site

convert the steam-generating powerhouse from burning coal as the

primary fuel to burning natural gas as the primary fuel and either No.

2 fuel oil or propane as backup fuel.

(1) The new boilers shall be equipped with low nitrogen oxides

technology.

(2) The site shall complete the powerhouse conversion (completion

of the powerhouse conversion) no later than 30 months after the

effective date of the permit.

(h) Monitoring, recordkeeping and reporting. (1) The permit shall

set forth monitoring, recordkeeping, and reporting requirements

sufficient to demonstrate compliance with the site-wide emissions caps.

The monitoring, recordkeeping and reporting requirements shall be

structured in a tiered system, such that the requirements become more

stringent as the site's emissions approach the total emissions cap.

(2) At a minimum, the permit shall require that the site submit to

the permitting authority semi-annual reports of the site-wide criteria

pollutant emissions (expressed as a 12-month rolling total) for each

month covered by the report. These reports shall include a calculation

of the total emissions cap, as well as, the emissions of sulfur

dioxide, nitrogen oxides, carbon monoxide, volatile organic compounds

and PM10.

(3) Any reports required by the permit to be submitted on an annual

or semi-annual basis shall contain a certification by the site's

responsible official that to his belief, based on reasonable inquiry,

the information submitted in the report is true, accurate, and

complete.

(4) Any records required by the permit shall be retained on site

for at least five years.

(i) Air quality analysis. The permittee shall demonstrate, prior to

permit issuance and on a periodic basis which shall be specified in the

permit, that emissions from construction or operation of the site will

not cause or contribute to air pollution in excess of any:

(1) maximum allowable increase or maximum allowable concentration

for any pollutant, pursuant to section 165 of the Act;

(2) National ambient air quality standard or;

(3) Other applicable emission standard or standard of performance

under the Act.

(j) Termination. (1) The permit may be terminated as provided in

this paragraph for reasons which shall include the following, as well

as any other termination provisions specified in the permit:

(i) If the Administrator or the permitting authority determines

that continuation of the permit is an

[[Page 52640]]

imminent and substantial endangerment to public health or welfare, or

the environment;

(ii) If the permittee knowingly falsifies emissions data;

(iii) If the permittee fails to implement the powerhouse conversion

pursuant to paragraph (g) of this section;

(iv) If the permittee receives four consent orders or two judgments

adverse to the site arising from non-compliance with this permit in a

five year period that are deemed material by the Administrator or the

permitting authority; or

(v) If the total emissions cap is exceeded.

(2) In the event of termination, the Administrator or the

permitting authority shall provide the permittee with written notice of

its intent to terminate the permit. Within 30 calendar days of the

site's receipt of this notice, the site may take corrective action to

remedy the cause of the termination. If this remedy, which may include

a corrective action plan and schedule, is deemed acceptable by the

Administrator or the permitting authority (whichever agency provided

written notice of its intent to terminate the permit), the action to

terminate the permit shall be withdrawn. Otherwise, the permit shall be

terminated in accordance with procedures specified in the permit.

(3) Termination of the permit does not waive the site's obligation

to complete any corrective actions relating to non-compliance under the

permit.

(k) Inspection and entry. (1) Upon presentation of credentials and

other documents as may be required by law, the site shall allow

authorized representatives of the Administrator and the permitting

authority to perform the following:

(i) Enter upon the site;

(ii) Have access to and copy, at reasonable times, any records that

must be kept under the conditions of the permit;

(iii) Have access at reasonable times to batch and other plant

records needed to verify emissions.

(iv) Inspect at reasonable times any facilities, equipment

(including monitoring and control equipment), practices, or operations

required under the permit;

(v) Sample or monitor any substances or parameters at any location,

during operating hours, for the purpose of assuring permit compliance

or as otherwise authorized by the Act.

(2) No person shall obstruct, hamper, or interfere with any such

authorized representative while in the process of carrying out his

official duties. Refusal of entry or access may constitute grounds for

permit violation and assessment of civil penalties.

(3) Such site, facility and equipment access, and sampling and

monitoring shall be subject to the site's safety and industrial hygiene

procedures, and Food and Drug Administration Good Manufacturing

Practice requirements (21 CFR parts 210 and 211) in force at the site.

(1) Transfer of ownership. The terms of the permit are transferable

to a new owner upon sale of the site, in accordance with provisions

specified by the permit.

(m) Permit issuance. The permitting authority shall provide for

public participation prior to issuing a permit pursuant to this

section. At a minimum, the permitting authority shall:

(1) Make available for public inspection, in at least one location

in the area of the site, the information submitted by the permittee,

the permitting authority's analysis of the effect on air quality

including the preliminary determination, and a copy or summary of any

other materials considered in making the preliminary determination;

(2) Notify the public, by advertisement in a newspaper of general

circulation in the area of the site, of the application, the

preliminary determination, and of the opportunity for comment at a

public hearing as well as written public comment;

(3) Provide a 30-day period for submittal of public comment;

(4) Send a copy of the notice of public comment to the following:

the Administrator, through the appropriate Regional Office; any other

State or local air pollution control agencies, the chief executives of

the city and county where the site is located; any State, Federal Land

Manager, or other governing body whose lands may be affected by

emissions from the site.

(5) Provide opportunity for a public hearing for interested persons

to appear and submit written or oral comments on the air quality impact

of the site, the control technology required, and other appropriate

considerations.

(n) Permit modifications. The permit shall specify the conditions

under which the permit may be modified by the permitting authority. The

permitting authority shall modify the permit in accordance with the

procedures set forth in this paragraph.

(1) Permit modifications that require public participation. For any

change that does not meet the criteria for an administrative permit

modification established in paragraph (n)(2)(i) of this section, the

permitting authority shall provide an opportunity for public

participation, consistent with the provisions of paragraph (m) of this

section, prior to processing the permit modification.

(2) Administrative permit modification. (i) An administrative

permit modification is a permit revision that:

(A) Corrects typographical errors;

(B) Identifies a change in the name, address, or phone number of

any person identified in the permit, or provides a similar minor

administrative change at the site;

(C) Requires more frequent monitoring, recordkeeping, or reporting

by the permittee;

(D) Allows for a change in ownership or operational control of a

source where the permitting authority determines that no other change

in the permit is necessary, provided that a written agreement

containing a specific date for transfer of permit responsibility,

coverage, and liability between the current and new permittee has been

submitted to the permitting authority.

(E) Updates the emission calculation methods specified in the

permit, provided that the change does not also involve a change to any

site-wide emissions cap.

(F) Changes the monitoring, recordkeeping or reporting requirements

for equipment that has been shutdown or is no longer in service.

(G) Any other change that is stipulated in the permit as qualifying

as an administrative permit modification, provided that the permit

condition which includes such stipulation has already undergone public

participation in accordance with paragraph (m) of this section.

(ii) An administrative permit modification may be made by the

permitting authority consistent with the following procedures:

(A) The permitting authority shall take final action on any request

for an administrative permit modification within 60 days from receipt

of the request, and may incorporate such changes without providing

the Environmental Protection Agency, the following provisions shall

apply:

(i) Where the delegate agency is not an air pollution control

agency, it shall consult with the appropriate State and local air

pollution control agency prior to making any determination under this

section. Similarly, where the delegate agency does not have continuing

responsibility for managing land use, it shall consult with the

appropriate State and local agency primarily responsible for managing

land use prior to making any determination under this section.

(ii) The delegate agency shall send a copy of any public comment

notice required under paragraph (n) of this section to the

Administrator through the appropriate Regional Office.

PART 60--STANDARDS OF PERFORMANCE FOR NEW STATIONARY SOURCES
