National Emission Standards for Hazardous Air Pollutants
Streamlined Development: Announcement and Request for Comments
AGENCY: Environmental Protection Agency (EPA).
[[Page 16089]] ACTION: Announcement and Request for comments.
-----------------------------------------------------------------------
SUMMARY: Section 112(d) of the Clean Air Act (CAA) directs EPA to
reduce emissions of hazardous air pollutants (HAPs) by requiring new
and existing sources to achieve an emissions standard attainable by the
maximum achievable control technology (MACT). The HAPs regulated under
Section 112 have been characterized as carcinogenic, mutagenic,
bioaccumulative, and causing other adverse health and environmental
effects. MACT standards are intended to significantly reduce these
effects.
This notice announces and requests comments on EPA's plan to use a
streamlined approach to promulgating MACT standards, termed MACT
Partnerships. Section 112(e) requires EPA to promulgate, on a strict
schedule, MACT standards for the more than 150 source categories of
HAPs listed pursuant to Section 112(c)(1). This large number of MACT
standards can not be addressed by the traditional approach to standards
development. The MACT Partnerships approach is designed to expedite the
regulatory development process and provide information for case-by-case
emission limitation determinations as required by Section 112(g) and
112(j) of the CAA. The MACT Partnerships approach is founded on the
mutual interests of all the major stakeholders, including EPA, States
and local agencies, industry, and environmental organizations. This
notice also announces the availability on the Technology Transfer
Network (TTN), one of EPA's electronic bulletin boards, of an initial
list of MACT standards being handled under MACT Partnerships.
DATES: Comments: Comments must be received on or before May 15, 1995.

SUPPLEMENTARY INFORMATION:
I. Background
Pursuant to Section 112(c) and 112(e) of the CAA, EPA published two
Federal Register notices laying out the source categories of HAPs
regulated under Section 112(d) of the Clean Air Act. In the first
Federal Register notice (57 FR 31578, July 16, 1992), EPA published the
source categories of HAPs as required under Section 112(c). In the
second Federal Register notice (58 FR 83941, December 3, 1993), EPA
presented the list in a regulatory schedule as required by Section
112(e). In addition to requiring the regulatory schedule, Section
112(e) requires EPA to develop MACT standards under Section 112(d)
according to this regulatory schedule.
There are consequences if EPA fails to set the MACT standards on
time. Thirty-nine MACT standards were targeted for promulgation by
November 1994, forty-three more by Nov 1997, and an additional eighty-
seven by Nov 2000. Section 112(j) of the CAA requires the States to
establish emission limitations, using a case-by-case determination of
what the Federal standard would have been if EPA fails to promulgate
Federal standards.
Case-by-case MACT determinations under 112(j) will require
substantial information and resources from State and local agencies,
industry, and environmental groups. Individually, State and local
agencies, industry and environmental groups have expressed their
interest in avoiding a significant number of case-by-case MACT
determinations. Accordingly, there appears to be a strong incentive for
EPA, State and local agencies, industry and environmental groups to
work together to enable EPA to promulgate the standards on schedule and
to gather information for 112(j) case-by-case MACT determinations.
II. Current Situation
The EPA is currently behind schedule on a number of MACT standards
due in November 1994 and potentially behind schedule on a number of
MACT standards due in November 1997. The EPA has promulgated about one-
half of the MACT standards due in November 1994. The EPA is already
under court-ordered schedules to complete many of the remaining MACT
standards due in November 1994. These schedules will ensure that
standards are promulgated before case-by-case MACT determinations would
be required by Section 112(j). The EPA has recently been served notice
by an environmental group indicating the group plans to file a petition
to compel EPA to promulgate the few standards due in November 1994 that
are not done nor on an existing court-ordered schedule.
In 1994, EPA had to postpone work on several of the MACT standards
due in November 1997 and November 2000 (the 7-year and 10-year MACT
standards) as a result of resource constraints. The EPA had to do so in
part to ensure that adequate resources were available for the court-
ordered MACT standards. These resource constraints have put EPA behind
on completing the 7-year and 10-year MACT standards.
The amount of work (and therefore resources) needed to complete the
7-year and 10-year MACT standards on time is difficult to predict.
Nevertheless, given the EPA's experience of the MACT standards
completed to date, EPA believes that the amount of work can be
significantly reduced by streamlining and re-engineering the way these
standards are developed. This work helps EPA appropriately
subcategorize source categories, define the MACT floor (see Section
112(d)), address emissions of special HAPs (e.g., Great Waters and
urban air toxics), and evaluate potential regulatory options beyond the
MACT floor.
Resources have been traditionally used by EPA to gather and analyze
essentially all the data and information necessary to reach the
regulatory decisions associated with standards such as MACT standards.
Many of the 7-year and 10-year MACT standards had not been studied by
EPA prior to recent years. Traditionally, EPA has found that it takes
about 4 years to develop national technology-based standards such as
MACT standards. Accordingly, to complete the 7-year MACT standards by
November 1997, EPA had to begin in earnest to work on these standards
early in 1994. Thus, to complete the 7-year MACT standards on time, EPA
needs to reduce the amount of work and time associated with these
standards.
In order to meet both the 7-year and 10-year deadlines, EPA has
concluded that it must develop new approaches to streamline the
standard setting process and to leverage its limited resources. To that
end, EPA is currently initiating a new process for developing MACT
standards that involves a partnership with states, industry, and
environmental organizations. This partnership, called MACT
Partnerships, is founded on the [[Page 16090]] mutual interests of all
the major stakeholders in the air toxics program.
For many source categories for which MACT standards are required,
State and local agency personnel have the expertise, information and
desire to provide technical assistance for the development of MACT
standards. Industry personnel are also invaluable sources of technical
expertise and data needed to develop MACT standards. In addition,
environmental groups have a thorough understanding of the interests of
the public and can assist in the development of as many MACT standards
as practical.
III. Streamlined MACT Development Approach
The MACT Partnerships program, as currently envisioned, involves
two phases for each MACT standard. The first phase involves development
of a ``presumptive MACT''. A ``presumptive MACT'' is not an emission
standard; but it serves as a statement of current knowledge of maximum
available control technologies and a basis for a decision on how to
develop the emission standard for the source category involved. The
second phase is the formal standard development process, which results
in a promulgated MACT standard for the source category.
In the first phase of the MACT Partnerships program, the
development of a ``presumptive MACT'', begins with two main steps: (1)
A meeting between EPA and State and local agencies, known as the
presumptive MACT meeting and (2) consultations with industry,
environmental and other interest groups. In the presumptive-MACT
meeting, EPA, and States review available information to estimate what
MACT would be if only this information were used in the determination.
This draft presumptive MACT then goes through a consultation stage
where industry and environmental groups are invited to comment on the
selected presumptive MACT. After this consultation, EPA and the State/
local agencies determine a final presumptive MACT and how best to
complete the development of a standard, with the normal opportunities
for public comment. This determination of a presumptive MACT and a
decision on how to complete development of a standard are the two
products of the first phase.
For the second phase of MACT Partnerships, EPA envisions the use of
one of three basic regulatory development paths: Adopt-a-MACT, share-a-
MACT, or a streamlined-traditional approach. In all cases, EPA would
eventually propose and then promulgate the MACT standard. The ``Adopt-
a-MACT'' path allows EPA to enter into an agreement with a State
wherein the State would accept primary responsibility for data
collection and analysis. Alternatively, a ``share-a-MACT'' path allows
states, industry or both to share with EPA the responsibility for
developing the underlying data and analysis from which EPA would
determine the MACT emission limitation. When no suitable partners can
be found, a ``streamlined-traditional'' path is the last alternative.
In the ``streamlined-traditional'' path, EPA would go through a
streamlined process of the traditional rule development, with a
presumptive MACT specification as an intermediate stage. No matter what
path is chosen, almost all standards would go through phase one,
namely, the presumptive MACT meeting and the second consultative stage.
The EPA has successfully worked with States and industry in the
development of presumptive MACT in two pilot projects. One project
concerned the MACT standard primary aluminum manufacturing. The States
of Washington and New York worked with EPA in the development of a
presumptive MACT. In addition, the Aluminum Manufacturers Association
and its member companies participated. For the second project, EPA
worked with the States of Wisconsin and Maryland to develop a
presumptive MACT for bakers yeast manufacturing. Both EPA and State
partners have worked with the industry to move from the presumptive
MACT to develop a MACT standard that is scheduled to be proposed in the
fall of 1995.
Currently, EPA is beginning more than 25 projects within the MACT
Partnerships program. Presumptive MACT meetings are scheduled over the
next several months. For the information of the public, EPA has
developed a table of these projects and has added it to the Technology
Transfer Network bulletin board system (TTN BBS) See Addresses section
above for information on how to access the TTN BBS. The list can be
found under the Clean Air Act (Rules/Guidance/Policy) section, Tittle
III: Hazardous Air Pollutants subsection and then the Status of Rules/
Projects portion of the TTN BBS.
In summary, the MACT Partnerships program is one way to pursue new,
assertive ways to develop MACT standards. MACT Partnerships is
characterized by EPA and State/localities working together with
industry and environmentalists to fulfill the mandate to set MACT
standards for sources of hazardous air pollutants. Given the mutual
interest of all the stakeholders and EPA's current ``budgetary''
situation within the air toxics program, EPA has begun redefining its
role in selected areas of MACT standard development for many MACT
standards as a coordinator and facilitator.
