MEMORANDUM

SUBJECT: Differences between maximum and composite monitor annual PM2.5

### design values by CBSA

FROM: Neil Frank, Acting Group Leader, Air Quality Analysis Group, OAQPS/OAR /s/

TO: PM NAAQS Review Docket (EPA-HQ-OAR-2007- 0492)

This memorandum examines the differences between the maximum and composite monitor annual PM2.5

### design values (DVs) in core based statistical areas (CBSAs). This examination has been done to help inform theEPA’s response to comments on the proposed rule for the national ambient air quality standards (NAAQS) for particulate matter (PM) (77 FR 38890, June 29, 2012) related to this issue, focusing in particular on comments submitted by the Utility Air Regulatory Group (UARG, 2012, Attachment 1, pp.2 to 6).1

### First, differences in DVs for two subsets of CBSAs are examined basedon 2006 to 2008 air quality data, consistent with the areas and time period used as a basis forUARG’s comment. Second, differences in DVs are examined for all CBSAs based on the most recent available data from 2009 to 2011.

Comparison of PM2.5

### DVs based on 2006 - 2008 data

In a comment on the proposed revisionto the level of the primary annual PM2.5

### standard related to the differences between maximum and composite monitor annual PM2.5

### DVs, UARG (2012, Attachment 1, p. 5) included a summary table (reproduced below as Table 1) showing the results of calculations of the 3-year averages of the maximum and composite annual PM2.5

### mean concentrations. The results were presented fortwo subsets of CBSAs described as follows: (1) those with DVs exceeding the current annual standard level of 15μg/m3

### and (2) those with DVs greater than 14.5 μg/m3

### and less than or equal to 15.0μg/m3

### . The commenter noted that the calculations were based on the full body of PM2.5

### monitoring data that the EPA relies on to identify DVs.2

1The EPA’s response to this and other significant comments on the PM NAAQS proposed rule will be presented in the preamble to the notice of final rulemaking on the PM NAAQS and in a related Response to Comments document (U.S. EPA (2012a). Responses to Significant Comments on the 2012 Proposed Rule on the National Ambient Air Quality Standards for Particulate Matter (June 29, 2012;77 FR 38890). Docket Number EPA-HQ-OAR-2007-0492. U.S. Environmental Protection Agency. December 2012. Available: http://www.epa.gov/ttn/naaqs/standards/pm/s_pm_index.html.).

2The database used by the commenter and by the EPA in this examination is available at: http://www.epa.gov/airtrends/pdfs/dv_pm25_2006_2008rev102809.xls

.

### 2 In attempting to reproduce the values in Table 1, we determined that the calculations presented by the commenter are flawed becausethey are not exclusively based on DVs that are appropriate for comparison to the annual PM2.5

### standard. We note that the DVs presented in the publicly available EPA DV listing2

### include those that are basedon incomplete data and those associated with unique source influence whichthe EPA has judged inappropriate for comparison to the annual PM2.5

### standard. The invalid DVsare indentified in the DV f ile as “inc-a, “inc-na” and ‘X’.

Another change is also necessary in order to attempt to reproduce the values in Table 1. The CBSA counts and data could be more closelymatched when the high concentration category includes maximum DVs equal toas well as greater than15.0μg.m3

### . Thus, the first category apparently should be categorized as“Greater than or equal to 15.0μg/m3

### ” and the second category as “Greater than 14.5 μg/m3

### and less than 15.0 μg/m3

### .” When this change is made, and all DVs are used, including invalid DVs, the results presented in Table 2 below were calculated. Even in this case, Table 1 was not exactly reproduced since only 10 CBSAs had DVs in the identified range for the second category of CBSAs with concentrations between 14.5 and 15.0

μg/m3



### .

This summary represents all CBSA DVs including invalid DVs in the EPA DV listing.

When the calculations are appropriately limited to use only valid DVs, the differences between maximum and composite monitor valuesare notably smaller than those presented in Table 1, which reflects the commenter’s reliance on invalid DVs. The differences between

### 3 average maximum and composite monitor DVs are reduced by approximately 1μg/m3

### for both DV categories. These results for 27 CBSAs with valid DVs are presented in Table 3 below

A complete listing of the maximum and composite average concentrations for all CBSAs is included as Attachment 1. This attachment shows the CBSA statistics based on valid 2006- 2008 design values and also based on all listed 2006-2008 designvalues; the number of valid design value monitoring sites and the number of total designvalue monitoring sites per CBSA are also shown.

Comparison of maximum and composite DVs for 2009 - 2011 data

The most currently available DVs for 2009 to2011 are presented below in Tables 4 and 5 for all CBSAs. The comparison between valid maximum and composite monitor DVs for the 123 CBSAs with multiple monitors is presented in Table 4. The CBSAs are rank ordered by the difference between the maximum and composite monitor DVs. Table 5 presents the DVs for the 208 additional CBSAs with a single monitor.This table is rank ordered by DV.

In considering all 123 CBSAs with multiplemonitors using only valid DVs, the average difference between the maximum and composite monitor DVs is 0.8μg/m3

### and the median difference is 0.6μg/m3

### . The 25th

### and 75th

### percentiles of the distribution of DV differences for all such CBSAs are 0.3 and 1.0μg/m3, respectively.
