1. EPA’s Ambient Air Monitoring StrategyCapita’s Recent Activities Consistent with this Strategy What we are doing EPA OAQPS Ambient Air Monitoring Strategy

2. Ambient Air Monitoring Strategy By Rich Scheffe Presented at ……… • Why? • What are the assumptions/constraints? • What are the operating principles? • What is it? • How will it be accomplished? • Who will do it? • What will it cost? • When will it be done? • How does air toxics fit in? EPA OAQPS Ambient Air Monitoring Strategy

3. Why? CAPITA Document: Megatrends Related to PM2.5 and Ozone • National investment > $100M annually • optimize resources…look for savings to support new needs • Major changes since original (~late 70s) network designs • air quality (typically lower levels of crit. Pollutants) • scientific findings and “needs” directing new measurements • e.g.: PM2.5, PM coarse, PM UF, toxics, Nitrogen, etc. (PAMS) • regionality and integration • technological advances • automated, optical, continuous, artifact free, miniaturized, highly resolved, multi-parameter…instrumentation (at reduced operational expense • monitoring community roles/communications • science reviews/advice (NAS, CASAC) • partnerships (Supersites, NARSTO) • ORD divestment in routine programs • Substantial criticism (NAS, NARSTO, GAO, OSTP, States) EPA OAQPS Ambient Air Monitoring Strategy

4. Our “Current” Network Strategy(It Just Grew…and Grew) • 3081 Sites Nationwide • 4920 monitors • 3480 collocated • 1440 single pollutant • 300+ TSP EPA OAQPS Ambient Air Monitoring Strategy

5. Criteria Pollutant Sampling SitesNote: an Abundance of Low Reporting Sites • In EPA OAQPS Ambient Air Monitoring Strategy

7. Summary of Concerns(Note: Ambient Air Data Produced by State and Local Agencies May Be the Most Valuable Environmental Database…but It Can Be Better…) • Data are not fully utilized and/or valued • lack of analysis and interpretation • millions of data points…many suspected to be meaningless • Inadequate integration across • separate programs, not optimized to complement one another • data generators and users (modelers, analysts, planners) • Apparent excess of criteria sites (NO2, CO, SO2, PM10, Pb) • many reporting low values • Abundance of old technology • requiring substantial operator involvement • often with inadequate resolution • Missing key locations and “species” • lack of regional coverage • missing: true NO2, NOy, HNO3, NH3, toxics, PM coarse, PM UF... EPA OAQPS Ambient Air Monitoring Strategy

8. Where Are We Going?Over the Next 3-7 Years CAPITA Document: AQ Management from Systems Analysis Perspective In addition to retaining core objectives (NAAQS comparisons, trends): • 3000 (now) to less than 2000 sites nationally • better job at fewer sites • leaner PAMS focused on meeting accountability objective • emphasis on type 2 emissions tracking sites • only episodic, less frequent sampling at other sites coinciding with planned modeling…i.e., the data will be used • substantial changes in PM monitoring • elimination of PM10 • reduction in PM2.5 mass (as dictated by review) • reduction in filter based samplers • increase in cont. technologies…mass and speciation • PM coarse network (PM10-PM5) …100-500 sites • air toxics network • enhanced regional/rural monitoring • e.g., N sampling for NOx SIP calls EPA OAQPS Ambient Air Monitoring Strategy

9. Where Are We Going?Cont. • Network assessments are performed continuously • based on changing priorities, data analysis needs and findings • value of data probed and challenged, and discontinued as needed • strong partnership across EPA, States, Academia, Industry • e.g., Supersite type programs... • Continued science advice replacing after program review • e.g., speciation expert panel • increased flexibility • to allow states to meet specific needs • enable responsive system to changing priorities • e.g., more short term monitoring EPA OAQPS Ambient Air Monitoring Strategy

11. What Are the Operating Principles? • Partnership across EPA and State/local agencies • Flexibility to balance between national (consistency) and local needs • e.g., PM2.5 speciation, air toxics CAPITA Document: National and Local AQ Analysis • Integrate…across pollutants and programs • Demonstrate data value…or lose it CAPITA Document: CAPITA PM and Ozone Analysis CAPITA Document: CAPITA Tools & Methods for AQ Analysis CAPITA Document: PM Analysis Workbook in Support of SIPS • Respond dynamically…to needs and science/technological change CAPITA Document: PM Analysis Website and Repository • Geographic equity…transition downscaling • Approximately level funding EPA OAQPS Ambient Air Monitoring Strategy

12. What Are the Obstacles? • Public concerns (I want my monitor) • Inertia from large infrastructure • Organizational • Compartmentalized data user-data generator groups • Tendency to build, and not review/assess • Resource burden • Infinite client base…consensus difficult EPA OAQPS Ambient Air Monitoring Strategy

13. What Is the Strategy? • Comprehensive review and rethinking of national monitoring programs • a systematic review of monitoring programs to determine: • what is working • what is excess • what are the integrating/complementary pieces • what needs to be added • acts on those findings • and institutes such actions to create a dynamic and responsive program to new priorities and objectives • scope (1o): criteria pollutants, PAMS, toxics…i.e., EPA air and S/L’s EPA OAQPS Ambient Air Monitoring Strategy

14. How Will This Be Accomplished? • Through assessments of monitoring programs • which ask probing questions • is monitoring meeting program and data quality objectives • are the data being used • what is the value • guide divestments (and investments) based on objective analyses • through communications • usual networks • plus…NARSTO, science meetings, special workshops • plus…communications strategy to alleviate public concerns CAPITA Document: PM Website ?? EPA OAQPS Ambient Air Monitoring Strategy

15. Who Will Do It? • Assessment pieces: • S/L agencies - internal agency level assessments • EPA ROs - workgroups to inventory network reviews, data analysis activities and review/modify monitoring regs. (Seitz 9/99 memo to RO ADDs) • new integrated “scientific/objective assessment” • air toxics concept paper and analysis/design effect • OAQPS RO MSRs • PAMS assessment • Assessment workgroup • EPA (OAQPS, RO, ORD), S/Ls • assimilate activities • manage new assessment • Management leadership • institutionalize assessments, data usage, and program integration EPA OAQPS Ambient Air Monitoring Strategy

Steering Committee EPA OAR, RO, ORD S/A, SAMWG Assessment Team EPA OAR, ORD, S/A Product groups S/L assessments EPA assessment workgroup EPA Reg review group Extramural tasks EPA OAQPS Ambient Air Monitoring Strategy

17. What Will It Cost? • Significant staff time and commitment (EPA, S/L agencies) • EMAD…2-5 dedicated FTEs • ESD, AQSSD, ITPID, OD • substantial personnel/staff time participation on committees, review, etc. • travel/communications • this will require dropping other activities • initial $500K investment for objective assessment (new request) EPA OAQPS Ambient Air Monitoring Strategy

19. What Are the Next Steps? • Establish assessment group…now • SAMWG meeting…10/04 • develop SOW for integrated assessment • activate RO workgroups • push/sell/market through all venues... EPA OAQPS Ambient Air Monitoring Strategy
