The overall goal of the Ozone Transport Commission (OTC) grant is to facilitate collaboration among the OTC jurisdictions, notably the State Environmental Commissioners/Secretaries, State Air Directors and their staff, to assist them in reducing ozone precursor emissions in their states and in representing their ozone related issues to the EPA. The focus of the OTC is to ensure real results in air quality improvement in the Ozone Transport Region. The OTC brings together the State members to coordinate reductions in air pollution to benefit the entire region. The Ozone Transport Commission (OTC or the Commission) is the single regional multi-state organization created under the Clean Air Act Amendments of 1990 (CAA) responsible for advising EPA on ground-level ozone and its precursor pollutant transport issues. The Commission is responsible for developing and implementing regional solutions to the ground-level ozone problem in the Northeast and Mid-Atlantic States. As directed under the CAA, EPA awards grants to the Commission under the authority of Section 106 of the CAA. Section 184 of the CAA established the Ozone Transport Region (OTR) that, by law, develops and recommends regional strategies for cleaning up air pollution.

The OTC Modeling Committee continued to move forward with its work plan to fulfill the charge from the Commission from the OTC Fall 2015 meeting and assist the other Committees with modeling support. The OTC and its Committees activities have increased significantly given the nexus of continued development of recommendations to facilitate the work of OTC states to meet the 2008 ozone NAAQS, continued work to assist states on the 110(a)(2)(d) good neighbor provision of the CAA, working collaboratively on regionally significant national measures under development from EPA, planning for states and regional activities under the revised ozone standard finalized on October 1, 2015, and working collaboratively with states across a region encompassing the eastern United States.
The Modeling Committee continued development and testing of the next generation, 2011based, modeling platform. This platform corresponds with EPA’s updated modeling platform and will use EPA data when appropriate to maintain consistency and reduce costs. The Modeling Committee has shifted its 2018 projection inventory development to include a 2017 projection year to support states attainment SIPs. The majority of the committee’s work focused on processing the second version of EPA’s emissions inventory for photochemical modeling. Work also began on the development of a technical support document for the modeling platform as well as documentation necessary for SIP submittal The OTC Modeling Committee continued to move forward with its work plan to fulfill the charge from the Commission from the OTC Fall 2015 meeting and assist the other Committees with modeling support.

The Stationary and Area Source (SAS) Committee and the Mobile Source Committee (MSC) continued to develop draft model rules for regional ozone control measures. During this quarter, the SAS Committee workgroups worked on addressing the charges given by the Commission at the 2017 Fall Meeting. The main charge required the Committee to perform technical analyses to calculate & document emissions reductions and develop cost estimates for the three SAS strategies formalized in the Good Neighbor State Implementation Plan (GN SIP) Resolution. The emissions reductions from these strategies which cover sources inside & outside of the OTR will be used in photochemical modeling to help OTC states include these measures in their GN SIPs. The Largest Contributors Workgroup worked on two of these strategies, i.e. calculating emissions reductions from and costs of: 1. optimizing the use of existing SCR or SNCR NOx control technology on coal-fired EGUs each day of ozone season, and 2. installing SCR or SNCR control technology on uncontrolled coal-fired EGUs & optimize use of such technology each day of the ozone season. Results of photochemical modeling (which is currently underway) and cost estimates (which are ready) will be presented to the Commission in the June meeting. The Control Measures Workgroup is working on the 3rd strategy which deals with calculating the emissions reductions gained from adopting the “OTC Model Rule for Control of NOx Emissions From Natural Gas Pipeline Compressor Fuel-Fired Prime Movers” in GN SIPs. This work is ongoing and the results are expected before the June meeting. In addressing the standing SAS charge requiring periodic updates of the OTC Model Rule on Consumer Products, the Consumer Products Workgroup revised and updated the current (Phase IV) Consumer Products Model Rule based on California standards. The new Phase V Model Rule includes several new categories, excludes a few, requires more stringent VOC limits for existing categories, has revised definition language, and an optional 3 year sell through limit for existing products that do not comply with VOC limits. The new Model Rule has been posted on the OTC website for public comment with a deadline of May 11, 2018. The Mobile Source Committee (MSC) began its work fulfilling the charge given to it at 2017 Fall Meeting. The MSC continued to follow developments with policies affecting aftermarket catalytic converters including having conversations with EPA including Regions 1, 2 and 3 in response to the resolution adopted by the Committee at the Spring Meeting. The MSC finished work on recommendations on policies to reduce vehicle idling regionally and continued work on an idling educational toolkit. The MSC completed collection of survey data concerning state progress in implementing several programs and initiatives. Finally, the MSC developed preliminary estimates of emission reductions that could be achieved both inside and outside the OTR. Both the SAS and MSC are working with a broad range of industry and other stakeholders, states and regional organizations both within and outside the OTR, and EPA offices to develop a framework for control measurement programs based on OTC Model Rules which are significant not only to eastern region but have national applicability in addressing the sources contributing to ozone formation and transport. In addition, on January 5, 2018 the OTC submitted its comments on EPA’s “Proposed Rule on the Repeal of Emission Requirements for Glider Vehicles, Glider Engines, and Glider Kits”. OTC opposes the adoption of this Proposed Rule as it could potentially result in an increase in air pollution with adverse public health impacts. OTC continued its efforts in coordinating with EPA to discuss state implementation plan development and related issues. Discussions with non-OTR states included the progress of ERTAC (the Eastern Regional Technical Advisory Committee) focused on developing a model for electricity generation and emissions from EGUs, a tool that incorporates state collected data and information on EGUs, and how to coordinate with other Regional Planning Organizations (RPOs) on modeling work and the need for federal measures to enable some OTC states attain the 2008 and the 2015 Ozone NAAQS standards. The OTC also participated in the Federal/RPOs technical collaborative including participating in a workgroup that developed broad recommendations for the next base-year to use in modeling platforms. OTC is participating and providing leadership in a multi-regional and EPA collaborative approach to develop emissions inventories and the next photochemical modeling platform. The OTC and other states continue to rely on the 2011 modeling platform for making projections, particularly with control measures applied. The OTC Modeling Committee and staff provide critical work to ensure the region’s technical analysis and decision-making are using the best modeling available.
