ENVIRONMENTAL PROTECTION AGENCY
[9912-13-ORD; Docket ID No. EPA-HQ-ORD-2013-0357]
Workshop To Obtain Input on Draft Materials for the Integrated
Science Assessment (ISA) for Sulfur Oxides (SOX): Health Criteria
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of Workshop.
SUMMARY: As part of the review of the air quality criteria for sulfur
oxides (SOX) and primary (health-based) National Ambient Air
Quality Standards (NAAQS) for sulfur dioxide (SO2), the
Environmental Protection Agency (EPA) is announcing a teleconference
workshop to evaluate preliminary draft materials that will inform the
development of the SOX Integrated Science Assessment (ISA)
for health effects. The workshop is being organized by EPA's National
Center for Environmental Assessment (NCEA) within the Office of
Research and Development and will be held on June 23-24, 2014.
Participation in the workshop will be by webinar or teleconference
DATES: The workshop will be held on June 23-24, 2014, beginning at 1:00
p.m. and ending at 4:00 p.m. each day.

I. Summary of Information About the Workshop
Section 109(d) of the Clean Air Act (CAA) requires the U.S. EPA to
conduct periodic reviews of the air quality criteria for each air
pollutant listed under section 108 of the Act. Based on such reviews,
EPA is to retain or revise the NAAQS for a given pollutant as
appropriate. As part of these reviews, NCEA assesses newly available
scientific information and develops ISA documents (formerly known as
Air Quality Criteria Documents) that provide the scientific basis for
the reviews of the NAAQS.
NCEA is holding this teleconference workshop to inform the Agency's
evaluation of the scientific evidence for the review of the primary
NAAQS for SO2. Section 109(b)(1) of the CAA defines primary
NAAQS as standards, ``the attainment and maintenance of which in the
judgment of the Administrator, based on such criteria and allowing an
adequate margin of safety, are requisite to protect the public
health.'' EPA intends to develop a separate ISA, and NAAQS review, for
the secondary (welfare-based) NAAQS for SOX, in conjunction
with a review of the secondary NAAQS for oxides of nitrogen. The
purpose of the workshop is to obtain peer input on the scientific
content of preliminary draft materials that will inform the development
of the draft health effects ISA. Workshop participants will review and
discuss preliminary draft materials on the atmospheric chemistry of and
human exposure to SOX as well as health effects evidence
from in vivo and in vitro animal toxicology, controlled human exposure,
and epidemiology studies. In addition, panel discussions will help
identify key studies or concepts within each discipline to assist EPA
in integrating relevant literature within and across disciplines. These
preliminary materials are not being released to the general public
before the workshop but will be used during the teleconference to guide
workshop discussions and inform the development of the draft health
effects ISA. This workshop is planned to help ensure that the ISA, once
developed, is up-to-date and focuses on the key evidence to inform the
scientific understanding for the review of the primary NAAQS for
SO2. EPA is planning to release the first external review
draft health effects ISA for SOX for review by the Clean Air
Scientific Advisory Committee and the public in December 2014.
II. Workshop Information
Members of the public may attend the teleconference as observers.
Space in the teleconference or webinar may be limited, and reservations
will be accepted on a first-come, first-served basis. Registration for
