Ohio EPA is now providing a revision to this plan for a 30-day public review and comment period. No revisions are being incorporated into Appendices B, C, E or F of this document at this time. These appendices remain as they were submitted by the July 1, 2016 deadline although they are being provided during the review period for clarity. This document, along with Appendices A, D and G are being updated to provide additional details regarding Ohio’s plan for fulfilling the requirements of Appendices A, C, D, and E of 40 CFR Part 58. This document addresses the Ohio air monitoring network, as it existed as of July 1, 2016, and as it is expected to be updated through June 30, 2017. Further, Ohio’s air monitoring network plan contained within meets all the requirements of Appendices A, C, D, and E of 40 CFR Part 58. Ohio EPA will submit the revised plan, and all appendices, with any comments received, to the US EPA Region V Regional Administrator. All comments received in the original and revised monitoring network plan can be found in Appendix H. Guidance and Priorities Ohio EPA follows the federal general guidance and requirements for air monitoring according to 40 CFR 58, Appendix D, including monitoring 1) areas of expected high concentrations, 2) areas of high population density, 3) areas with significant sources, 4) general background concentration sites and 5) areas of regional transport of a pollutant. Not all air pollutants need to have sites for all of these categories. In addition to the above, the Air Directors in the Region 5 states of Ohio, Michigan, Indiana, Illinois, Wisconsin and Minnesota have adopted the following air monitoring objectives: 1) Areas of high concentration and high population, provide timely air quality data to the public, support compliance with the National Ambient Air Quality Standards (NAAQS) and control strategy development and support air pollution research studies 2) Multi-pollutant monitoring such as the NCore sites 3) Source-oriented monitoring such as required monitoring for lead, nitrogen dioxide and sulfur dioxide 4) Rural monitoring and medium size city monitoring 5) Environmental justice monitoring 6) School air toxics monitoring A fundamental consideration for all air monitoring projects and sites is that the monitoring locations meet US EPA requirements and that the state and local air agencies are available to operate and maintain the sites and equipment, to provide sample analyses, and are available for data collection and reporting. Network Changes The plan for Ohio’s Air Monitoring Network for 2016-2017 is to make changes as required, or necessary, for the air monitoring network. A quick-view of Ohio’s current monitoring network for each of the criteria pollutants can be found in Appendix A. Network maps for Page | 1 each of the US EPA criteria pollutants, critical summary statistics from 2015 monitoring data, and three-year averages of the 2013-2015 monitoring data are presented in Appendix E. All planned, proposed and potential network changes for each local and district office monitoring network are tabulated in Tables 5 and 6 below. A larger detailed table provided at the end of this document contains a listing of Ohio’s complete air monitoring network with proposed changes noted. Unplanned site changes occur to the network each year. Changes or temporary interruptions of sampling may occur because of events such as building or roof maintenance, construction, change of ownership of the site, or other changes at the site that require moving the instruments. Some changes that may not be planned could include adding sites for complaint areas or for a new or proposed facility. Other changes that are planned may not be implemented due to unforeseen circumstances, such as the inability to secure a new site or because of other constraints. All site and parameter changes are made in consultation with, and approval of, the US EPA Region V air monitoring staff. Ohio EPA retains the right to install and operate ambient air quality monitors that go beyond federal minimum requirements without federal approval. PM2.5 FRM Filter Based and PM2.5 Continuous Network For sites that monitor very fine particulate matter (PM2.5), Ohio EPA expects to continue with monitoring or sampling using the PM2.5 Federal Reference Method (FRM) at the majority of the sites as they existed at the beginning of 2016. Ohio’s 2016-2017 PM2.5 monitoring network can be seen in Appendix A. Maps depicting locations of each site are presented in Appendix E. Table 1 below identifies the minimum FRM monitoring sites required under 40 CFR Part 58, Appendix D, Table D-5. 40 CFR Part 58, Appendix D, Section 4.7.2 requires continuous PM2.5 analyzers in the same MSAs be equal to at least one-half (round up) of the minimum required FRM monitoring sites listed in the 40 CFR Part 58, Appendix D, Table D-5. Appendix D of this document includes an analysis showing Ohio’s existing network meets the minimum siting requirements in 40 CFR Part 58, Appendix D for both PM2.5 FRM monitoring and PM2.5 continuous monitoring in Ohio’s Metropolitan Statistical Areas (MSA), taking into account known network changes as outlined in this document. Design values to compare to the NAAQS can be found in Appendix E of this document.
