Subject: Science Advisory Board (SAB) Consideration of EPA Planned Actions in the Spring
2014 Unified (Regulatory) Agenda and their Supporting Science
Dear Administrator McCarthy:
As part of its statutory duties, the Science Advisory Board (SAB) recently concluded discussions about
possible review of the science supporting major EPA planned actions associated with the Spring 2014
Unified (Regulatory) Agenda and Regulatory Plan. The EPA Office of Policy provided notice of the
release of this information on May 23, 2014. The SAB held a public teleconference on January 23, 2015,
to discuss whether to review the science supporting any of the planned regulatory actions in that agenda
in order to provide advice and comment on the adequacy of the science, as authorized by section (c) of
the Environmental Research, Development and Demonstration Authorization Act.
The SAB focused its attention on three major actions identified by the EPA Office of Policy as being
planned but not yet proposed as of the date the Agenda was published in the Federal Register. At the
public teleconference, the SAB decided that it will not undertake review of the science supporting any
actions in the semi-annual regulatory agenda at this time. It notes, however, that one action, the
Interstate Transport Rule for the 2008 Ozone NAAQS (2060-AS05), is not at a point in its regulatory
development that the EPA could provide sufficient information for the SAB to consider whether Board
review is necessary. The SAB requests that the Office of Air and Radiation provide the SAB with more
information about the scientific basis for this action as soon as that information becomes available. The
SAB plans to reconsider potential Board review at that time.
The SAB appreciates the information provided by the EPA Office of Policy and the EPA program
offices describing the planned actions, associated scientific questions, and agency plans for scientific
analyses and peer review. The written information provided and the results of fact-finding discussions
with EPA Staff are available on the SAB website.
