5. 2007 Haze SIP Narrative Measures Visibility conditions (2000-04 baseline) Current Natural Emissions (mostly 2002) Point Area Mobile Fire, Dust, et cetera International Emissions (2018) Visibility Goals (2018) 2013 SIP Check Approach Monitoring Data Trends Emissions Trends In-state* All contributing states Other (fire, dust, international) On-The-Books Specific to RHR BART Other point ? Area ? Smoke Management ? Same categories as 2002, based on Federal Programs, other State rules, plus BART and any additional measures (growth/control projections for some categories, others held constant) Estimated using modeling of the “Reasonable Progress” strategies for most and least impaired days, then adjusted using monitoring Relative Response Factors – exact value of final visibility goals are SIP decisions by each state Review completeness and trends in monitoring data Based on latest & best regional emissions inventories: 1) Examine how trends in various emissions types and scales compares with the narrative prepared for SIP submittal* 2) Examine what is “now” On-The-Books and re-project 2018 3) Adjust SIP (measures and / or goal) Identify needs for comprehensive regional emissions tracking and complete/representative Class I area monitoring data Assess post-2013 need for additional regional analysis and planning to begin now for 2018 SIP submittal  These measures may include non-BART emissions limits, emission limits on source categories, and modification to smoke management plans, et cetera.  * – This analysis for the 2013 SIP check will establish accountability for emissions reductions/management strategies for that state identified in each 2007 haze SIP – did they track as anticipated? The 2007 SIP should require the state to complete a review of its emissions and spell out the circumstances of how a SIP revision prior to 2018 would be triggered. If things have changed enough, that State needs to re-do the projections based on its changed emissions and either re-affirm that it will be on target for 2018, or make the needed changes to emissions strategies and / or the SIP RP goals written into each state’s 2007 SIP.

6. What kinds of regional technical work and capabilities have been completed to date? Needs beyond 2007…

7. What Emissions Analysis & Control Work has the WRAP Done? Diverse interests working together through the WRAP have made great progress to reduce air pollution across the West in recent years. Some of the highlights include: – – Emissions of sulfur dioxide from Western coal-fired power plants declined 40% between 1998 and 2005. A reduction of ~50% is projected with full implementation of state and tribal Regional Haze Plans over the next ten years. – – Working through the WRAP, the states of Arizona, New Mexico, Oregon, Utah and Wyoming submitted the nation’s first State Implementation Plans under the Regional Haze Rule. These plans implement the recommendations of the Grand Canyon Commission. – – New EPA standards for engines and fuel will greatly reduce emissions from motor vehicles and off-road equipment in coming years. Mobile sources are the largest source of nitrogen oxide emissions in the West. These new standards will reduce mobile source emissions of nitrogen oxides by 70% over the next 15 years, even as the West continues to grow. – – Western states and tribes, working closely with federal land managers, continue to improve their smoke management programs to ensure that air quality impacts are minimized when prescribed burns are necessary on public and private land. The WRAP is implementing a fire tracking system to help land managers and air quality planners manage controllable smoke impacts on a regional basis.

8. WRAP region Emissions Analysis & Control Work, continued The state Regional Haze Plans due to EPA in December 2007 will address the long-standing issue of emissions from grandfathered sources. The sulfur dioxide emission reductions mentioned above are part of the solution. The 2007 regional haze plans will also implement Best Available Retrofit Technology (BART) for nitrogen oxide emissions. In 2005, the WRAP completed the first-ever regional inventory of emissions from oil and gas sources. Phase II of that effort is now underway. Phase II will yield better estimates of current and future emissions and identify ways to reduce emissions from this sector. WRAP is providing direct assistance to state and local governments and fleet owners in an effort to reduce diesel emissions through retrofit programs.

9. Challenges Remain The West is a vibrant and rapidly growing region. Even as we make progress on some air quality issues, new challenges emerge. Population growth, increased energy development, and tighter federal standards must be addressed if we are to see continued air quality improvements and meet the requirements of the Clean Air Act. In recent years, drought and warmer temperatures have resulted in degraded air quality due to increased dust emissions and wildfires. The members of WRAP (states, tribes, and federal agencies) along with key stakeholders (industry, environmental interests, local governments, and academia) remain committed to working together through WRAP to address these challenges. States and tribes are also using the WRAP as a forum to share information on climate change and greenhouse gas emissions, including development of a greenhouse gas inventory and a voluntary registry.
