Improvements in Data Collection and Reporting
Spring Membership Meeting 2002
PM 2.5 Data CompletenessReport Card
• Improvements in collection and reporting
– SAMWG and EPA Working Together– State and Local Agency efforts
• Noteworthy results in 2001– 1103 station operated all 4 quarters– No systematic equipment issues
• AQS issues being resolved
• Continued focus is warranted for all pollutants.
Current 2001 reporting by EPA Region
• Region 1 77%
• Region 2 69%
• Region 3 88%
• Region 4 86%
• Region 5 88%
• Region 6 80%
• Region 7 92%
• Region 8 87%
• Region 9 79%
• Region 10 89%

Operated With Data 11+ Samples 75% Complete
1172 sites operated during the year1101 sites operated all 4 quarters699 sites (63% of 1101) have 4 complete quarters (> 75%)864 sites (78% of 1101) have 11+ samples in all 4 quarters

AQS 4/15/02
Designations / Design Values (d.v.'s) based on 3 years of dataTo show attainment (A), sites must have 75%+ data capture in each of the 12 quarters
To show nonattainment (NA), sites must have at least 11 samples in each of the 12 quartersEPA Regional Administrators have the discretion to use less complete data
Completeness Criteria for PM2.5 Annual Standard
What Do We Know (today) About PM2.5 Completeness, 1999 - 2001
(as of April 15, 2002)1222 sites operated some time in 1999-2001
764 Sites operated all 12 Quarters
Overview status of PM2.5 Monitoring Network
All sites color coded. Big dots meet 4 Q completeness, small dots don't
Sites with 11+ samples in each quarter and mean01 >15.0 [19%]Sites with 75% in each quarter and mean01 < 15.0 [48%]Sites w/ out 11+ samples in each Q and mean01 > 15.0 [4%]Sites w/ out 75% in each Q and mean01 < 15.0 [29%]
PM2.5 Completeness, 1999 - 2001
(Operated all 4 quarters 2001 - 1103 Sites)
Year by year PM2.5 Levels -2001
Data from AQS on April 15, 2002
Sites with 11+ samples in each quarter and d.v.
>15.0 [153]Sites with 75% in each quarter and d.v.
< 15.0 [121]Other sites (not usable for designations.... without RA
discretion) [490]
PM2.5 Completeness, 1999 - 2001(Operated all 12 quarters - 764 Sites)
April 15th Results: Color = All 12 Q's meet completeness criteria
Base Case - Regulatory Data Completeness
What Could Happen With Data Available Today ?
Sites with d.v. >15.0
[80]Sites with d.v. < 15.0
[410]
Sites that do NOT meet 12 Q completeness criteria as of April 15, 2002 ! (Black dots from Base)
Which Direction Do Incomplete Sites Lean ?
NOTE:In some areas, 'incomplete' sites don't match well with 'complete' sites!
Many of the 80 sites are redundant within an MSA’s with complete data showing >15.0 annual average.
Look for an MSAupdate on AIRWEB in May.

Keys to Success
• Refine networks for efficient operation
• Improvement as AQS matures
• Reinforce expectations for timely reporting
• Focus on new equipment issues
