1. The annual standard design values shown here are calculated in accordance with 40 CFR Part 50, Appendix N 

(2006). The annual standard design value (i.e., the 3-year average annual mean concentration) is computed at each site 

by averaging the daily FRM samples taken each quarter, averaging these quarterly averages to obtain an annual average, 

and then averaging the three annual averages. (Note that special rules apply if an area has been approved for spatial 

averaging.) The NAAQS level for the annual standard is 15.0 micrograms per cubic meter (μg/m ~. In general, EPA 

regulations require at least 75% data capture in each quarter of a consecutive 3-year period in order for a design value to 

be valid. However, if an annual mean (or 3-year annual design value) is over the level of the standard, less data (i.e., 11 

samples per quarter for the corresponding 4 quarters) are sufficient to deem that mean valid. Further, EPA regulations 

and guidance permit data substitution under certain circumstances in order to to consider design values as valid that 

otherwise would be considered incomplete. The infoiYnation presented in this update is based on data after applying the 

substitution protocols.

1. The annual standard design values shown here are calculated in accordance with 40 CFR Part 50, Appendix N

average, and then averaging the three annual averages. (Note that special rules apply if an area has been approved for 

spatial averaging.) The NAAQS level for the annual standard is 15.0 micrograms per cubic meter (μg/m 3 ). In 

general, EPA regulations require at least 75% data capture in each quarter of a consecutive 3-year period in order for 

a design value to be valid. However, if an annual mean (or 3-year annual design value) is over the level of the 

standard, less data (i.e., 11 samples per quarter for the corresponding 4 quarters) are sufficient to deem that mean 

valid. Further, EPA regulations and guidance permit data substitution under certain circumstances in order to to 

consider design values as valid that otherwise would be considered incomplete. The information presented in this 

update is based on data a8er applying the substitution protocols.

2. Monitoring sites with an annual deesign value status of'X' hev been determined by EPA to represent unique microscale or 

middle scale locations are not used for comparison to the annual PM2.5 NAAQS. The 2012 revisions to 40 CFR 58 require a 

formal exclusion justification to be described in the annual State monitoring plan.
