ENVIRONMENTAL PROTECTION AGENCY
[FRL-6848-2]
Petition for Secondary National Ambient Air Quality Standards for
Nitrogen Dioxide, Sulfur Dioxide, and Fine Particulate Matter and
Related Request
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The EPA is announcing receipt of a petition for rulemaking
under section 109 of the Clean Air Act (CAA), to promulgate revised
secondary national ambient air quality standards (NAAQS) for pollutants
associated with the formation of acid rain, including nitrogen dioxide
(NO2), sulfur dioxide (SO2), and fine particulate
matter (PM2.5). The petition was submitted by
representatives of the States of New York, Massachusetts, Maine, New
Hampshire, Connecticut, Rhode Island, and Vermont in a letter to the
EPA Administrator, dated October 26, 1999. In that letter, the States
request EPA to address what they assert to be a wide range of adverse
environmental effects associated with these pollutants through the
mechanism of revised secondary NAAQS. In addition, EPA has received a
related request from the U.S. Department of the Interior (DOI) in a
letter to the EPA Administrator, dated July 19, 2000, to address many
of the same adverse environmental effects associated with the same
types of air pollutants, and with ozone (O3) that DOI
asserts are occurring in national parks and wilderness areas.
To consider and respond to this petition and related request
properly, EPA plans to review relevant scientific information, and to
consult with the public and potentially affected stakeholders to ensure
that decisions in response to these requests are based on the best
available information.
DATES: Comments and associated information and analyses should be
submitted on or before December 7, 2000.

Background
The establishment, review, and revision of NAAQS are governed by
two sections of the CAA. Section 108 (42 U.S.C. 7408) directs the
Administrator to identify certain pollutants which ``may reasonably be
anticipated to endanger public health and welfare'' and to issue ``air
quality criteria'' for them. These air quality criteria are to
``accurately reflect the latest scientific knowledge useful in
indicating the kind and extent of all identifiable effects on public
health or welfare which may be expected from the presence of [a]
pollutant in the ambient air * * *.''
Section 109 of the CAA (42 U.S.C. 7409) directs the Administrator
to propose and promulgate ``primary'' and ``secondary'' NAAQS for
pollutants identified under section 108 of the CAA. Section 109(b)(2)
of the CAA defines a secondary NAAQS as one, ``the attainment and
maintenance of which, in the judgment of the Administrator, based on
[the section 108] criteria, is requisite to protect the public welfare
from any known or anticipated adverse effects associated with the
presence of such air pollutant in the ambient air.'' Welfare effects as
defined in section 302(h) of the CAA (42 U.S.C. 7602(h)) include, but
are not limited to, ``effects on soils, water, crops, vegetation,
manmade materials, animals, wildlife, weather, visibility, and climate,
damage to and deterioration of property, and hazards to transportation,
as well as effects on economic values and on personal comfort and well-
being, whether caused by transformation, conversion or combination with
other pollutants.''
Section 109(d)(1) of the CAA requires periodic review and, as
appropriate, revision of existing air quality criteria and NAAQS. The
EPA's most recent decisions following the review of air quality
criteria and the existing secondary standards for NO2,
SO2, PM, and O3 were published in the Federal
Register on October 8, 1996 (61 FR 52852), April 21, 1993 (58 FR
21351), and July 18, 1997 (62 FR 38652 and 62 FR 38856), respectively.
Information concerning the welfare effects of these pollutants and the
rationales for EPA's decisions as to revision of the existing secondary
standards at those times can be found in those notices, as well as in
the notices of proposed rulemaking which preceded EPA's final
decisions.
Summary of Northeast States' Petition
Representatives of the States of New York, Massachusetts, Maine,
New Hampshire, Connecticut, Rhode Island, and Vermont submitted a
petition to the EPA Administrator, dated October 26, 1999, pursuant to
the Administrative Procedures Act, 5 U.S.C. Sec. 553(e), requesting
that EPA commence rulemaking to promulgate revised secondary NAAQS. The
petitioners suggest that the acid rain provisions in title IV of the
CAA do not go far enough to ensure full recovery of sensitive
ecosystems. The petitioners cite several recent Federal studies in
support of
[[Page 48701]]
their assertions that effects are occurring which are adverse to the
public welfare, and that these effects result from pollutants
associated with acid rain, including NO2, SO2,
and PM2.5. More specifically, the petitioners assert that
reports such as the National Acid Precipitation Assessment Program's
(NAPAP) Biennial Report to Congress: An Integrated Assessment and
Nitrogen Oxides: Impacts on Public Health and the Environment (EPA452/
R-97-002) document continued and increasing damage caused by acid
deposition to the lakes and forests in the Northeastern States and
other parts of the nation, as well as other environmental effects
(e.g., visibility impairment, eutrophication of coastal estuaries,
damage to vegetation from tropospheric ozone and the depletion of
stratospheric ozone) associated with these pollutants and their
transformation products. Moreover, the petitioners assert that damage
is sufficiently serious and widespread to be considered national in
scope, such that revised secondary NAAQS are an appropriate approach
for addressing such effects.
Related Request From DOI
The DOI has requested in a letter to the EPA Administrator, dated
July 19, 2000, that EPA initiate rulemaking within its various
authorities under the CAA that would provide appropriate regulatory
mechanisms by which states could require protection of air quality
related values (AQRVs) in Federal Class I areas (i.e., national parks
and wilderness areas) from both new and existing sources of air
pollution. More specifically, the DOI asks that EPA consider the use of
the provisions of the CAA dealing with prevention of significant
deterioration (PSD) to promulgate a general rule that would require
affected States to revise their State implementation plans (SIPs) to
remedy existing, and prevent future, adverse AQRV impacts. The DOI
letter asserts that AQRVs are being adversely affected by air pollution
at numerous national parks and wilderness areas, with effects at
various locations including acidification of streams, surface waters,
and/or soils; eutrophication of coastal water; visibility impairment;
and foliar injury to vegetation. The DOI acknowledged that revised
secondary NAAQS might be one approach to help mitigate the effects of
concern to Federal land managers responsible for protection of AQRVs in
Class I areas, but proposes that EPA also consider using the PSD
provisions, as well as other approaches identified in its letter that
could provide some protection in the short-term, before more general
rulemaking can be promulgated, to address localized impacts specific to
Class I areas.
Solicitation of Comments and Information
The Administrative Procedure Act (APA) does not require EPA to
provide notice and solicit public comment before deciding upon its
response to petitions or other requests for rulemaking. Nonetheless,
EPA has decided in this instance to solicit public comment and
additional information and analyses relevant to the issues raised by
these requests. The EPA is particularly interested in receiving
comments and information regarding: (1) Any ongoing or planned research
that will become available in the peer-reviewed literature in the near
future on the welfare effects of the pollutants noted in the letters
and their atmospheric transformation products, or on environmental
responses to existing emission control programs; (2) the scope and
magnitude of the impact on the environment of welfare effects
associated with these pollutants and their atmospheric transformation
products; (3) the variability in geographic impacts, frequency, timing,
seasonal implications, severity, and extent of the effects and
differences in site characteristics where those effects occur; and (4)
various alternative approaches and mechanisms that may be suitable for
addressing these effects consistent with EPA's authority under the CAA.
The EPA will consider any relevant comments and information submitted
in response to this notice, together with information provided by the
petitioners and the DOI and information in the existing records cited
in today's notice, before making any decision concerning a response to
these requests for rulemaking. If EPA decides to respond to the States'
petition or DOI's request by commencing rulemaking under the CAA, we
will publish a notice of proposed rulemaking in the Federal Register,
providing further opportunity for public review and comment before
adopting any final rules.
