This exploratory study will describe LIEP characteristics that may influence the quality of programs delivered to English Learners (EL) in grades K through 12. The major purpose of this project is to gather data from the field that yields an initial portrait of well-designed and implemented LIEPs, and to provide practical guidance to local educators on selecting, designing, implementing and evaluating LIEPs. This is important because before this, there have been no systematic attempts to determine the characteristics of LIEPs for ELs in kindergarten through grade 12 and to describe contextual factors that contribute to their effectiveness.

Information About IRIS EPA’s IRIS is a human health assessment program that evaluates quantitative and qualitative risk information on effects that may result from exposure to chemical substances found in the environment. Through the IRIS Program, EPA provides the highest quality science-based human health assessments to support the Agency’s regulatory activities. The IRIS database contains information for more than 540 chemical substances that can be used to support the first two steps (hazard identification and dose-response evaluation) of the risk assessment process. When supported by available data, IRIS provides oral reference doses (RfDs) and inhalation reference concentrations (RfCs) for chronic noncancer health effects and cancer assessments. Combined with specific exposure information, government and private entities use IRIS to help characterize public health risks of chemical substances in a site-specific situation and thereby support risk E:\FR\FM\12APN1.SGM 12APN1

II. Information Specific to This Document

    Two sections of the Clean Air Act (CAA) govern the establishment 
and revision of the NAAQS. Section 108 (42 U.S.C. section 7408) directs 
the Administrator to identify and list certain air pollutants and then 
to issue air quality criteria for those pollutants. The Administrator 
is to list those air pollutants that in her ``judgment, cause or 
contribute to air pollution which may reasonably be anticipated to 
endanger public health or welfare;'' ``the presence of which in the 
ambient air results from numerous or diverse mobile or stationary 
sources;'' and ``for which * * * [the Administrator] plans to issue air 
quality criteria * * *'' Air quality criteria are intended 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 * * *'' 42 U.S.C. 7408(b). Under section 
109 (42 U.S.C. 7409), EPA establishes primary (health-based) and 
secondary (welfare-based) NAAQS for pollutants for which air quality 
criteria are issued. Section 109(d) requires periodic review and, if 
appropriate, revision of existing air quality criteria. The revised air 
quality criteria reflect advances in scientific knowledge on the 
effects of the pollutant on public health or welfare. The EPA is also 
required to periodically review and revise the NAAQS, if appropriate, 
based on the revised criteria. Section 109(d)(2) requires that an 
independent scientific review committee ``shall complete a review of 
the criteria * * * and the national primary and secondary ambient air 
quality standards * * * and shall recommend to the Administrator any 
new * * * standards and revisions of existing criteria and standards as 
may be appropriate * * * .'' Since the early 1980's, this independent 
review function has been performed by the Clean Air Scientific Advisory 
Committee (CASAC).
    Presently, EPA is reviewing the NAAQS for Pb.\1\ The draft document 
announced today is being developed as part of the planning phase for 
the review. This phase began with a science policy workshop to identify 
issues and questions to frame the review. Drawing from the workshop 
discussions, a draft integrated review plan (IRP) has been prepared 
jointly by EPA's National Center for Environmental Assessment, within 
the Office of Research and Development, and EPA's Office of Air Quality 
Planning and Standards, within the Office of Air and Radiation. This 
document will be available on the EPA's Technology Transfer Network

    The draft IRP is being made available for consultation with CASAC 
and for public comment. Comments should be submitted to the docket, as 
described above, by April 28, 2011. The CASAC consultation on this
