U.S. EPA Region 9
• Annual Network Plan defined• History• Challenges for CA agencies• Content of an Annual Network Plan• Current process
– S/L Agency’s submittal process– EPA’s review/approval process– How to address deficiencies– Changes to networks outside the ANP process
• Impacts on regulatory actions – why do we care?

• 40 CFR 58.10: “The plan shall include a statement of purposes for each monitor and evidence that siting and operation of each monitor meets the requirements of appendices A, C, D, and E of this part, where applicable.”
• FRM/FEM instruments at the following stations: SLAMS, Ncore, STN/CSN, State speciation, SPM, PAMS
• It is more of a documentation tool than a planning tool.
What is an Air Monitoring Annual Network Plan (ANP)?

U.S. EPA Region 9
• ANP reg. clarified in 2006 Monitoring Rule Revision• 2007:
– EPA R9 provided a guidance memo – First plans due July 2007
• 2011: EPA was sued on approval of South Coast AQMD’s ANP –litigants claimed that South Coast AQMD was not meeting a monitoring requirement
• 2012: – EPA R9 provided an updated guidance memo– EPA developed a new ANP review process which includes a
checklist to serve as the “basis for approval”• 2012 and 2013 ANPs reviewed under new process• Comments/litigation for other ANPs on-going

• CARB plus 21 districts that operate air monitors• We get 14 ANPs for CA agencies• Multiple agencies can be involved in one dataset• Requirements are at local, MSA, state, and PQAO
level– Local: siting– MSA: minimum monitoring requirements– State: background and transport sites– PQAO: collocation requirements
Challenges for CA Agencies

• Timing– ANPs are due to EPA by July 1 each year– Public inspection/comment period: 30-day public
inspection/comment period required prior to submittal to EPA – posted by May 31
• Coordination: Areas with multiple agencies operating sites require coordination and synthesis in advance of May 31– local district with CARB sites in its area – all ANP
information for CARB site(s) should be in district plan
– Local district sites included in CARB plan – all ANP information for local district site(s) should be in CARB plan

• EPA R9 reviews ANPs against checklist for completeness and accuracy and sends a response letter
• EPA R9 categorizes response in 3 categories– Approval: complete and meets CFR
requirements– No action: incomplete information or not
meeting CFR requirement (other than minimum monitoring requirement)
– Disapproval: not meeting minimum monitoring requirement

• The ANP process is iterative• EPA recommends addressing deficiencies in next
year’s ANP submittal• ANPs can be revised and resubmitted in the same
year
Current ProcessHow to Address Deficiencies

• Legal challenges– EPA approvals must be defensible and well-documented– Deficiencies in monitoring operations can result in legal
basis to discount data
• Infrastructure SIPs– requires approvable network of monitoring sites
• Attainment/Non-attainment decisions– Data not collected according to Federal regulations can
result in data not being used for regulatory decisions– Lack of approved network plan can prevent a regulatory
action from moving forward
