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 the EPA’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 based on 2006 to 2008 air quality data, consistent with 

the areas and time period used as a basis for UARG’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 revision to 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 for two subsets of CBSAs described as follows: (1) 

those with DVs exceeding the current annual standard level of 15 μg/m3

 and (2) those with DVs 

greater than 14.5 μg/m3

 and less than or equal to 15.0 μg/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

 The 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.). 2

 The 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 .

In attempting to reproduce the values in Table 1, we determined that the calculations 

presented by the commenter are flawed because they 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 based on incomplete data and those 

associated with unique source influence which the EPA has judged inappropriate for comparison 

to the annual PM2.5 standard. The invalid DVs are indentified in the DV file 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 closely matched when the high concentration category 

includes maximum DVs equal to as well as greater than15.0 μg.m3. Thus, the first category 

apparently should be categorized as “Greater than or equal to 15.0 μg/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

. 

Table 2. Average of Maximum and Composite DVs for DVs > 14.5 μg/m3

 (2006-2008). 

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

 

 Design Value Range n maximum composite difference

Greater than or equal to 15.0 33 17.2 14.3 2.9 

Between 14.5 and 15.0 10 14.8 13.5 1.3 

 

When the calculations are appropriately limited to use only valid DVs, the differences 

between maximum and composite monitor values are 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 1 μg/m3

 for both 

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

Table 3. Average of Maximum and Composite DV for DVs > 14.5 μg/m3

 (2006-2008). 

Design Value Range n maximum composite difference

Greater than or equal to 15.0 21 16.8 14.8 2.0 

Between 14.5 and 15.0 6 14.8 14.2 0.5 

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 design values; the number of valid 

design value monitoring sites and the number of total design value monitoring sites per CBSA 

are also shown. 

Comparison of maximum and composite DVs for 2009 - 2011 data

 The most currently available DVs for 2009 to 2011 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 multiple monitors using only valid DVs, the average 

difference between the maximum and composite monitor DVs is 0.8 μg/m3

 and the median 

difference is 0.6 μg/m3

. The 25th and 75th percentiles of the distribution of DV differences for all 

such CBSAs are 0.3 and 1.0 μg/m3, respectively.
