Air Monitoring Outlook Gregg Worley, US EPA Region 4 Spring Grants/Planning Meeting May 22, 2013
Overview • Current NAAQS Review Schedule • Near-road Monitoring • PM2.5 Continuous FEM Data Handling • Data Certification • Monitoring Network Plans • Region 4 PM2.5 Monitor Analysis
Current Schedule for Ongoing NAAQS Reviews NOTES: Underlined dates indicate court-ordered or settlement agreement deadlines Blue: finalized rules, Green: upcoming rules For more information see: http://epa.gov/ttn/naaqs/
Region 4 Near-road Monitoring Regulatory Deadlines for Near-road Monitoring • NO2: 1st Monitor Jan 2014; 2nd Monitor Jan 2015 • PM2.5: January 1, 2015 • CO: January 1, 2015 • NO2: January 1, 2014 • PM2.5: January 1, 2017 • CO: January 1, 2017 • NO2: January 1, 2017 • PM2.5: not required • CO: not required
Near-road Site Information in 2013 Network Plans • Agencies with current funding for a near-road site (CBSA population> one million) must submit information for approval of the near-road site in the upcoming monitoring plan. • Agencies may also submit an addendum to the 2012 monitoring plan for quicker approval of the near-road site. • A list of minimum information for near-road site approval was included in EPA’s 2012 Network Plan response to applicable agencies
PM2.5 Continuous Federal Equivalent Method (FEM) Data Handling
PM2.5 Continuous FEM Data Handling • PM NAAQS final rule [§58.11(e)] allows certain PM2.5 continuous FEM data to be excluded from the NAAQS if: • Performance criteria are not met when assessed with collocated FRM(s); (See §58.11(e) and Table C-4 to Part 53) • Monitoring agency requests exclusion of data; • EPA Regional Office approves exclusion of data.
PM2.5 Continuous FEM Data Handling • Recommend monitoring agencies do the following: • If your agency is planning to request exclusion of data: • Report data to AQS parameter code 88101 • Use Special Purpose and Non-Regulatory monitor types • Apply for exclusion of data already collected as soon as possible. • So that design value calculations are produced with the right data • Ensure your Annual Monitoring Network Plan and AQS are aligned with the metadata information cited in §58.10(b). • EPA is has developed a template and guidance document to assist monitoring agencies in this effort. • Emailed to monitoring contacts on 4/22/13
Data Certification New Process in 2013
Data Certification – The Basics • Process required by 40 CFR §58.15 • Formal statement attesting to ambient data completeness and accuracy • Submitted by states to EPA on annual basis: Due May 1 for previous calendar year’s data • Process that combines a required action followed by a discretionary EPA review
Why Change the Process? • Data reviews are manually intensive, often involving hundreds of individual monitors per state • AQS flag setting decision(s) have lacked explicit criteria for a “Y” or “N” • Process is overwhelmed by early and regular certification submittals, therefore AQS flag setting has been haphazard at best for current and historical data
What Has Been Done? • Reporting tool developed in AQS that summarizes key information needed to support timely and consistent reviews (AMP600) • AQS flagging process partially automated to reduce manual workload • Workload redistributed to make task more manageable • Longer term – consider CFR changes to focus on criteria pollutants only (e.g., drop PAMS, CSN)
Old vs. New OLD PROCESS • Certifying Agency (CA) submits certification letter, AMP450, AMP450NC (if applicable), AMP255 reports to EPA Region Administrator. • EPA Region Office staff makes sure the submitted documentation is complete and forwards it to OAQPS. • OAQPS staff reviews, notifies RO staff of problems. • RO staff communicates with affected agency to resolve problem. • When problem is resolved or irresolvable, OAQPS is notified. • Certification flags (“Y” or “N”) are manually added at some point after that. NEW PROCESS • Certifying Agency (CA) adds certification flags to AMP600 Report, noting any differences with the AQS recommendation • The CA prints and signs the AMP600. • The CA submits their signed certification letter, signed AMP600, and AMP450NC (if applicable) to Region 4 APTMD • APTMD staff reviews the documentation and adds EPA determination flags (in many cases within a day or two).
2012 Data Certification Status • This year agencies had the option of using either the old or new processes • Almost ALL Region 4 agencies opted for the new process • To date, nearly all certifications have been reviewed and completed by EPA Region 4.
2013 Network Plans • For the 2013 plans, due July 1st, please make sure to include: • The NO2 related information that was requested in EPA’s 2012 approval letters • Exclusion requests for any PM2.5 FEMs that you think should not be comparable to the NAAQS
PM2.5 Monitor Analysis: Background • The last comprehensive analysis of the Region 4 PM2.5monitoring grant allocation was conducted 15 years ago when the network was established. • Many changes (monitor additions and shutdowns) have occurred to the network over those years.
PM2.5 Monitor Analysis: Objective and Approach • Objective: Conduct an analysis of monitoring work to determine if CAA section 103 grant funding is equitably distributed between Region 4 S/L agencies. • Only monitors whose data are entered into AQS, per 40 CFR, were counted in this analysis. • Weighting factors were developed for each type of PM2.5 monitor (e.g., continuous, FRM, speciation, etc.). Factors were based on OAQPS cost estimates of operating the monitor types.
PM2.5 Monitor Analysis: Timeline • Late CY12: Region 4 has pulled PM2.5 monitor data from AQS. • January: S/Ls reviewed the data and provided corrections. S/Ls also evaluate the reasonableness of the weighting factors using their knowledge of the effort needed to operate the monitors. • March: Region 4 corrected the data and sent it back to S/Ls for QA check. • May 21-23: Region 4 to present the data to S/L Directors.
PM2.5 Monitor Analysis: Timeline cont’d • June/July: Region 4 Grant Allocation Workgroup convenes to evaluate data and options. It is envisioned that options would include a no action and one or more reallocation options. • August: Workgroup makes recommendation to EPA Region 4 Air Director. • October: If a decision to reallocate funds is made, the reallocation would occur in FY14.
