WESTAR National Air Monitoring Steering Committee Update Spring Business Meeting 2010 Denver, CO Bruce Louks, Idaho DEQ
NAAQS – Monitoring Update • NO2 – Final rule • Near – road monitoring population threshold changed to 500,000. • Site criteria for near-road monitoring based on AADT, fleet mix, roadway design, congestion patterns, terrain, meteorology. • EPA will provide site development guidance and would like input from monitoring organizations. • 40 additional sites dedicated to susceptible and vulnerable populations; subject to EPA Regional Administrator approval. • Sites identified in July 1, 2012 network plans. • Monitoring begins January 1, 2013.
NAAQS – Monitoring Update • Pb – rule pending, comments closed February 2010, final in fall 2010. • Source – oriented monitoring schedule • > 1 tpy monitors already in place • > 0.5 tpy monitors one year from promulgation (fall 2011). • NCore monitors beginning Janurary 1, 2011. • Pb monitoring plans included in July 1, 2010 network plan. • EPA seeking national contract for laboratory analysis. • EPA plans to develop more generic FEMs to relieve burden on S& L’s to develop their own.
NAAQS – Monitoring Update • O3 – rule pending; final in August 2010. • CBSAs 50,000 to 350,00 require monitoring. • In each state, 3 non-urban monitors • Micropolitan (10,000 – 50,000) statistical area • far-downwind transport zones of currently well-monitored urban areas • federal, state, or Tribal lands, including wilderness areas that have ozone-sensitive natural vegetation and/or ecosystems • Monitoring begins January 1, 2012 (could be delayed, or phased in over 2 years). • Monitoring plans due July 1, 2011. • EPA will re-evaluate monitoring seasons using 2006-2008 data. • NACAA and WESTAR comments have been submitted.
NAAQS – Monitoring Update • SO2 – pending; final in June, 2010. Comments closed February, 2010. • Population weighted exposure index thresholds (PWEI) determine number of monitors required in CBSAs. Monitors located in maximum source-impact areas, based on modeling. PWEI can be updated after 2009 NEI available. Burden is on states to ensure accuracy of NEI data. • Additional monitors based on that state’s contribution to national SO2 emissions; minimum of one. States will determine the specific location of these monitors within state boundaries (which can be inside or outside of CBSAs), with EPA approval. • Monitoring begins January 1, 2013. • Monitoring plans in July 1, 2012 network plans.
NAAQS – Monitoring Update • CO – NPRM due October, 2010. • Likely to be near-roadway component. • Issue with number of historical monitors supporting SIPS/maintenance plans. • PM – Draft Policy Assessment released March, 2010. ANPR expected November 2010. • Consideration to secondary standard to address “visibility impairment”. This would most likely be a short-term (1 -3 hour) indicator of PM mass or light extinction (nephelometer).
Air Toxics • Issue with quality of acrolein data • School Air Toxics (SAT) data will be invalidated due to QA issues. Data will be flagged, not null coded. • EPA and Steering Committee working on solution for acrolein data in AQS (including NATTS). • EPA’s ORD working on laboratory and collection method issues. • NACAA and EPA will begin discussion for process whereby monitoring organizations may opt out of NATTS monitoring requirements for certain compounds or classes of compounds. • EPA forming committee to scope assessment of NATTS monitoring network. NACAA has representative on the committee. First meeting scheduled for February, 2010. • Community Scale Air Toxics grants proposed to resume in FY11. Priority may be granted to outcome-oriented projects (community programs, EJ, children’s health).
Funding Issues • White House FY11 proposed budget adds $82.5M for STAG grants, of which: • $42M for core workload • $15M (§103) for mandated monitoring - capital costs • $15M is well short of estimated $80-100M needed to implement new and anticipated monitoring requirements. • Question: Can $42M “core workload” funds can be used for operations and maintenance of ambient air monitoring systems? • Phase-out of §103 PM monitoring funds ($42.5M) will occur over four years, beginning FY11 – annual increments (percentages) not yet determined. • Funds transitioned to §105. • Raises issues with additional “match” requirements during a period where monitoring organizations are struggling with budgets. • However, additional matching funds will increase monitoring funds.
