NO2 UpdateProposal on monitoring rule revisions
going to OMB late July 2012Proposal now published for 30-day comment
periodRevise deadlines to a phased implementation,
commencing 1/1/2014 thru 1/1/2017
Near roadORD study in Las Vegas and DetroitHighest NO2 and BC nearest to road,
decreasing with distanceNo significant gradient with PM

SO2 UpdateStakeholder meetings held on
implementationDiscussions on monitoring vs. modelingFavorable opinions on a threshold
2000 tpy 480 sources nationwide≅Monitoring
How many sites needed? Who pays? How long?Modeling
Cheaper, but does not always reflect realityNeed rulemakingInternal EPA discussions occurring

Secondary NOx/SOx Update3 areas proposed for pilot studies
NE / AdirondacksSE / AppalachiansRockies / possibly Colorado
Pilot studies to use existing infrastructure and take place between 2013 and 2018
Pilot studies to include NOy and trace SO2Eutrofication and acidification a concern in
Rockies and westHigher acidification in the eastern US

PM UpdateNew PM proposal
Retain 24-hr PM10 at 150 ug/m3Retain 24-hr PM2.5 at 35 ug/m3Reduce annual PM2.5 to 12 or 13 ug/m3Add secondary visibility-basedRevise monitoring requirements
Discussions focused on secondary NAAQSApplicabilityEquipmentArea covered
Lot of comments submitted to EPA

National Air Toxics Trends StationsFirst multi-year assessment performed
2005-2007 vs. 2008-2010Next one in 2013
2nd draft of report just releasedOverall, a decreasing trend for a number of air
toxicsData very useful for NATA modeling validation,
trends and health risk benchmarksNeed to:
Look at redundant sites and eliminateLook at CR+6 possibly for sources/special studiesLook at DQO’sEnsure that required MDL’s are being met

PAMS Re-Engineering
Reduce number of sites
Add PAMS in ozone non-attainment areas
26 “Required” sitesO3, NOx, VOC’sUpper air met?
Some “flexible” sitesO3, NOx
Good data toolsAuto-GC shootout

Proposed

Use of Non-State MonitoringConcerns on how to deal with non-state
monitoringReference
NPS, USFS, BLM, EPA, Tribal, Other
Non-reference USFS, NOAA, DRI, GO3 Project, Private, Municipal, Other
Issues:How to handle exceptional event data and flagging?How to handle violations with non-state reference
analyzers?How to handle violations with non-reference
analyzers?Inclusion in monitoring plans?

Community/Citizen MonitoringLot of new technologies upcoming
SmallerEasier to useSome good, some questionable
Data readily available via internetQuestion: How much citizen involvement
is desired for monitoring?Need to focus efforts on what are really the
issues, not just the perceptionsNeed better coordination on sensor appsNeed better communication with
communitiesEPA holding stakeholder meetings

FundingNear-road NO2
Phase 1 awarded by end of July 2012Working on securing $5 million for Phase 2 in 2013
PM2.5 transition from 103 to 105Start in FY 2013 (…assuming not under a CR)10% per year over 4 years
PAMS transitionLink to 2014 O3 NAAQSFY 2015 or 2016 earliest for network change$2.2 million available
IMPROVEStatic or decreasing budgetSome site to be cut or sample frequency decrease
