Gordon Pierce WESTAR Fall Business Meeting Tempe, AZ April 16, 2012
National Monitoring Steering Committee meeting held in Denver, Oct. 25-26 Presentation on most items at the Fall WESTAR Business Meeting Additional items have been discussed since last meeting
NO 2 ◦ “Phased Implementation Approach” going forward (formerly called the “Build and Hold” plan) 50 total sites in CBSA > 1 million 25 sites in 2012, to be operational by 1/1/2013 25 sites in 2013, to be operational by 1/1/2014 $200,000/site = $5 million/year (103 funds) ◦ Will assess data after 1 or 2 years and determine if additional sites needed or if need to do a rule change ◦ Look at near-road sites as the core of a multi- pollutant network ◦ The issue: Potential for legal challenges as does not meet CFR requirements…who takes the liability?
NO 2 Phased Implementation Approach Issues ◦ Inconsistency among EPA regions as to how to handle approval of network plans that do not meet CFR requirements for number of NO 2 sites by 1/1/2013 ◦ MSC has looked at 3 approaches: Put all network info into 1 plan for EPA approval Put everything but NO 2 in 1 plan and NO 2 only in a 2 nd plan for EPA approval, so EPA can take no action on the NO 2 plan Rulemaking to change CFR requirements ◦ NACAA has presented to EPA, and EPA is likely looking to do a rulemaking to stagger NO 2 site installation dates
Secondary NOx/SOx ◦ Rule has been issued…April 3, 2012 ( effective June 4, 2012 ) ◦ No change to existing secondary NAAQS for SO 2 and NO 2 ◦ AAI (aquatic acidification index) was being looked at, but decision made that not enough information yet ◦ Plans to do a field study Characterize NOy and SOx in 3-5 sensitive ecosystem areas Develop ecoregion-specific factors and AAI values Evaluate monitoring methods for NOy an SOx ◦ Plan is to use CASTNET sites PM ◦ New NAAQS proposal expected in June 2012
