A. Annual PM2.5 standard design values shall be rounded to the nearest 0.1 μg/m3 (decimals 0.05 and greater are rounded up to the next 0.1, and any decimal low er than 0.05 is rounded dow n to the nearest 0.1). The annual standard is 15.0.

B. 24-hour PM2.5 standard design values shall be rounded to the nearest 1 μg/m3 (decimals 0.5 and greater are rounded up to the nearest w hole number, and any decimal low er than 0.5 is rounded dow n to the nearest w hole number). The 24 hour standard is 35.

CASAC/EPA Review of PM2.5 NAAQS

By Court Action, EPA Was Instructed To Review its 2006 Review/Revisions To The PM2.5 NAAQS

On July 8, 2010, EPA released its 2nd External Draft of its review of the science

EPA Currently Concludes: Consideration should be given to an annual

standard of 11 –13 ug/m3 and leave the daily standard at 35 ug/m3

Consideration could be given to an annual standard of 11 ug/m3 and a daily standard of 30 ug/m3

OZONE UPDATE

Tennessee 1997 Ozone NAAQS Attainment Status

Knoxville Area

A Court Vacature of the EPA Part I 8-Hour Ozone Rule Eliminated The June 15, 2007 Deadline For Subpart I Basic Area SIP Submittals.

A New Rule Has Been Proposed By EPA To Address Subpart I Basic Areas That Are Still Not Attaining The 1997 Standard. See January 16, 2009 Federal Register - Link: http://edocket.access.gpo.gov/2009/pdf/E9-806.pdf

If This Rule Is Unchanged And Goes Final, Knoxville Will Be Subpart II Moderate for the 1997 standard.

Tennessee Submitted Its Bid For Redesignation To Attainment (2007-2009 Data) on July 14, 2010.

Nitrogen Dioxide Implementation Timeline

Milestone DateState DesignationRecommendations to EPA

January 2011: One year following promulgation (Based on existing network data – 2008-2010 data – 2010 data would not be fully QA’d)

DesignationsJanuary 2012: EPA designates all/most areas as “unclassifiable” (because near road monitors not in place)

New NO2 Monitoring Network

January 1, 2013: All monitors operating – future designations from this data ~2016-2017

Background

On July 15, 2009, the EPA proposed to strengthen the primary NAAQS for nitrogen dioxide (NO2).

Proposed changes would protect public health, especially the health of sensitive populations.

On January 22, 2010 EPA announced the final revisions to the NAAQS for nitrogen dioxide (NO2).

New Standard Levels

EPA is adding a new Primary 1-hour NO2 standard at a level of 100 parts per billion (ppb).

EPA will retain the current Primary annual average NO2 standard of 53 ppb.

EPA will also retain the current Secondary annual average NO2 standard of 0.053 ppm.

EPA revised the AQI for NO2 to incorporate the new 1-hour standard revisions with new levels set for the Good, Moderate, USG and Unhealthy categories where none existed before.

Form of Standard

The 1-hour primary standard is met when the 3-year average of the annual 98th percentile of the daily maximum 1-hour average concentration is less than or equal to 100 ppb.

The annual primary standard is met when the annual average concentration in a calendar year is less than or equal to 53 ppb.

The secondary standard is attained when the annual arithmetic mean concentration in a calendar year is less than or equal to 0.053 ppm, rounded to three decimal places.

Note: The 98th percentile for a year corresponds approximately to the 8th highest daily maximum.

EPA Schools Air Toxics Monitoring Program

Background

USA Today Article dated Dec. 8, 2008 USA Today teamed with Johns

Hopkins University and University of Maryland

Modeled and conducted screening measurements of air toxics around a number of schools across the country

Come up with list of 437 schools and ranked them worst to best

Study History

New EPA Administrator told staff in January 2009 to investigate the schools air toxics issue

Staff selected 62 schools across the country to conduct testing around

Short term study- 60-day sampling period

Reports for the 4 TN schools may be viewed at: http://www.epa.gov/schoolair/schools.html

School Selection and Toxics

Four of the 62 schools EPA selected are in Tennessee

Ashland City Elementary:• Metals (Manganese)

Lakeview Elementary:• Metals (Manganese)

Greene County High School:• (Disocyanates)

Vonore Middle School:• (Disocyanates)

EPA wanted to get the study off the ground immediately

NC Public Nuisance Lawsuit Against TVA

On July 26, 2010, the United States 4th Circuit of Appeals reversed and remanded the order of the lower court that granted relief for NC against TVA on their claim of public nuisance.

The judgment of the 3 judges was unanimous

NC can ask for appeal En Banc (10 Judges on the 4th Circuit Bench) or go to the Supreme Court if they elect to fight it.
