Terms of Clearance: In accordance with 5 CFR 1320, EPA is required to include the following information in its submission for information collection request review and approval: (1) supporting statements to show compliance with PRA requirements and other associated laws; (2) a description of the regulatory text applicable to the ICR including submission specifications; (3) a clear description of the data elements being collected under the ICR; (4) copies of the data collection instrument(s) and/or screen shots of the electronic portal where the reporting requirements are submitted to EPA (with the control number and burden statement included); (5) a detailed discussion of how information is submitted and the extent to which electronic reporting is available; (6) evidence of consultation with respondents (by actively reaching out to stakeholders as permitted by the PRA) to ensure the supporting statement's accuracy on availability of data, frequency of collection, clarity of instructions, accuracy of burden estimate, relevance of data elements, and similar PRA matters; and (7) discussion of how EPA addressed substantive concerns raised by respondents and other stakeholders during consultation and in response to comments received on FR notices. In addition, supporting statement A should use the standard 18 question SS-A format. More information can be found at https://pra.digital.gov/clearance-process/supporting-statement/. In addition, in lieu of using worst case burden estimates please review actual submissions and adjust estimates accordingly. Please also upload associated guidance and ensure that guidance is updated to include this OMB Control Number where, if at all, the collection of informaiton is discussed.

Abstract: This ICR includes estimates for the submission and processing of emissions and emissions-related information and ambient air dispersion modeling reporting and activities, associated with the 40 CFR part 51 Requirements for Preparation, Adoption and Submittal of Implementation Plans, as they apply to the 2010 1-Hour SO2 Primary NAAQS. These data and information are collected by various state and local air quality management agencies and reported to the EPA. State and local air management agencies chose to submit either monitoring or modeling information in order to meet the initial and on-going requirements, as applicable, to characterize air quality concentrations in areas with specific emissions sources identified under the final SO2 DRR. This proposed ICR Renewal adopts (with some revisions) the estimates contained in the original ICR, and it includes burden estimates for the development, submittal, and processing of the information described above to meet ongoing requirements under the DRR during the period from January 1, 2023 to December 31, 2025. For those state and local air management agencies that chose ambient monitoring rather than modeling to characterize air quality around specific emissions sources during the initial phase of DRR implementation (2016), such monitoring is required by Subpart BB of Part 51, and information collections associated with initial ambient air quality monitoring required under Part 51 were initially included in the prior versions of the DRR ICR. Currently, the DRR requires that ongoing monitoring continue to meet the operational constraints and requirements in 40 CFR Part 58, and any collections associated with ongoing monitoring under the DRR are now covered by the Part 58 ICR (EPA ICR No. 0940.29; OMB No. 2060-0084). Therefore, ongoing collections of ambient monitoring data have been removed from coverage by the DRR ICR to avoid duplicative burden calculations. Future renewals of the Part 58 ICR will continue to cover any collections of ongoing ambient air monitoring data that were initiated under Subpart BB of Part 51, so long as any of those monitors continues to operate. The principal legal authority for this information collection is the Clean Air Act (CAA), 42 U.S.C. 7403, 7410, 7414(a), and 7511a, from which the 40 CFR part 51 regulations were promulgated. In accordance with the requirements of the DRR, where an air agency finds in the annual emissions report for a source subject to the DRR that emissions have increased in an area, the state or the EPA may determine that the state must submit updated air quality modeling data for the area to determine whether or not the area is meeting the 2010 1-Hour SO2 Primary NAAQS. The information requirements included within this ICR are necessary to provide EPA with ambient air quality data, which includes emissions data and/or modeling data, to determine the air quality status of specific areas around the country, to make attainment decisions for those areas with respect to the NAAQS, to assist in developing necessary control strategies in order to ensure attainment of the NAAQS in those areas, to assess national trends in air pollution, to inform the public of air quality, and to determine the populations exposure to various ambient air pollutants. EPAs ability to achieve its goal of attaining the 2010 SO2 1-hour NAAQS in all areas of the United States is directly dependent upon the availability of ambient air quality data (emissions and/or modeling data) requested in this information collection. Additionally, EPA, state and local air quality management agencies, environmental groups, industrial groups, and academic organizations use these data to study atmospheric chemistry, e.g., the formation and fate of SO2 to determine the most appropriate and effective control strategies necessary to reduce air pollution.

Short Statement: Air agencies that elected under subpart BB of part 51 to conduct ambient monitoring for listed DRR sources are responsible for collecting ambient air quality data information and submitting these data electronically to EPA's Air Quality System (AQS) and other voluntary databases. While information collections associated with initial ambient air quality monitoring under part 51 were included in the prior version of the DRR ICR, any collections associated with ongoing monitoring are now covered by the part 58 ICR for ambient monitoring. This information collection and the associated burden are captured under the Ambient Air Quality Surveillance 40 CFR part 58 ICR (OMB #2060-0084, EPA ICR# 0940.29). Ongoing collections have been removed from the DRR ICR to avoid duplicative burden calculations. The prior renewal of this ICR estimated a maximum possible burden of $5,100,000 annually for modeling sources. While that was correctly noted in the other ICR materials, that amount was incorrectly entered in the currently approved ICR as $510,000. As a result, the ROCIS entry of this ICR appears to show a significant increase in burden while in reality -- with an estimated cost range of $150,700 to $3,014,000 annually -- there is an actual burden decrease in EPA's estimates. This ICR reflects a decrease in the maximum possible burden of $2,086,000 annually for modeling sources. This decrease is due to the reduced number of listed sources for which states chose to conduct air quality modeling to meet their DRR requirements.
