### Air Quality Design Values Used for the Second Round of Area Designations for the 2008 Lead National
Ambient Air Quality Standards

On November 12, 2008, the U.S. Environmental Protection Agency (EPA) published a rule revising the level of the Lead (Pb) National Ambient Air Quality Standards (NAAQS) from 1.5 micrograms per cubic meter (ųg/m3) to 0.15 ųg/m3 measured as total suspended particles. The EPA designated areas for the revised Pb NAAQS in two

rounds. The EPA designated certain areas, where 2007

- 20 09 monitoring data existed showing a violation, as nonattainment in 2010 (75 FR 71033, Nov. 22. 2010). The EPA is completing the second round of designations for the 2008 Pb NAAQS by establishing air quality designations for all other areas in the United S tates. These designations were generally based on the most recent 3 years of quality assured air quality monitoring data (2008

- 2010) , which are shown below. Where a monitor has a design value for 2008

- 2010 above the Pb standard, the EPA has designated the area that violates the standard and any area that contributes to the violating area as “nonattainment.” As discussed in the preamble to the final designations, where a monitor has data for 2011 available but not yet quality assured and certified that are exceeding the standard, the EPA designated the area as “unclassifiable.” All other areas in the country, where monitors have a design value meeting the standard, have incomplete air quality monitoring data for 2008

- 2010 (but no data exceeding the standard) , or have no monitors, and are not contributing to a violating area, have been designated as “unclassifiable/attainment.”

1 The level of the 2008 NAAQS for Pb is 0.15 micrograms per cubic meter (μg/m 3 ) not to be exceeded in any 3

- month period. The design value for the 2008 lead NAAQS is the maximum rolling 3

- month lead

- TSP average over a 3

- year period.

2 The design values shown here are computed for the 2008

- 2010 design value period using Federal Reference Method or equivalent data reported by States, Tribes, and loca l agencies to EPA's Air Quality System (AQS) as of 7/12/2011. Concentrations flagged by S tates, Tribes, and local agencies as affected by exceptional events (e.g., high winds, wildfires, volcanic eruptions, construction) and concurred by the associated EPA Regional Office are not included in the calculation of these design values. Although th e indicator for the 2008 Pb NAAQS is Pb

- TSP at "local conditions" (i.e., actual temperature and pressure; parameter 14129), 2008 Pb

- TSP data reported in "standard temperature and pressure" (i.e., 25 ° C, 760 mmHg; parameter 12128) are also considered valid for NAAQS comparisons and related attainment/nonattainment determinations if the sampling and analysis methods that were utilized to collect that data were consistent with previous or newly designated FRMs or FEMs and quality assurance requirements were m et.

3 DVs that are bolded and colored (red or blue) are valid. All other design values are invalid and are shown in normal black font. For counties with invalid design values, the value shown in this column is the highest valid 3

- month mean for sites in the county if at least one valid 3

- month mean exists. If the county had sites that reported FRM/FEM data for the 2008

- 2010 period but none of the sites had any valid 3

- month means, the DV shown is the highest 3

- month mean without regard to validity ; these latter cases are underlined if present.
