Terms of Clearance: It's taken so long to find and communicate with the program contacts that we need to close out this ICR and start over. Upon resubmission, please clarify all of the changes in burden and provide a briefing if requested for the OIRA desk officer. It is very unclear why the agency is requesting a reduction of 83,595 hours in burden which is over 70% of the total burden hours currently (110,543).

Abstract: This ICR addresses reporting and recordkeeping activity defined by the final Data Requirements for the 2010 1-Hour Sulfur dioxide (SO2) Primary National Ambient Air Quality Standards rule (SO2 Data Requirements Rule) (See 80 FR 51052, August 21, 2015). Through the SO2 Data Requirements Rule and the initial ICR, EPA required states to characterize ambient air quality around SO2 sources with emissions that were greater than 2,000 tons per year (tpy) or that were otherwise included as a listed source. In this ICR, EPA addresses ongoing requirements that apply to listed sources for which air agencies chose the monitoring pathway as well as sources for which air agencies chose the modeling pathway. The number of listed sources for which air agencies chose the monitoring pathway, and thus are required to submit ongoing monitoring information, are 73 sources in 24 states (77 monitors total). The number of listed sources for which air agencies chose the modeling pathway that are required to submit ongoing data reports, and, potentially, updated modeling, are 170 sources in 43 states. Air quality management agencies that elected to conduct ambient monitoring for listed DRR sources are responsible for reporting ambient air quality data information and retaining quality assurance/quality control records and monitoring network documentation. Where possible these activities are carried-out electronically using EPAs Air Quality System (AQS). Air quality management agencies that elected to conduct air quality modeling of the areas containing listed DRR sources to provide the necessary air quality data to EPA are responsible for submitting ongoing data reports. If EPA requires that the air agency conduct updated air quality modeling for the area, the air agency has 12 months to submit the updated modeling to EPA.

Short Statement: The adjustments in burden requested result, in large part, from EPA having resolved much of the uncertainty that resulted in inflated calculations in the previous ICR issued to support the SO2 Data Requirements Rule. The final rule gave the air monitoring agencies the flexibility to characterize air quality using either appropriately sited ambient air quality monitors or modeling of source emissions. The previous ICR calculated burden for both the monitoring and the modeling scenarios assuming each one would be used by all possible sources. The agencies have now submitted their selected approach and this ICR revises the burden estimates to accurately reflect agencies having chosen to conduct either ambient air monitoring or air quality monitoring. As a result of agencies having now positively affirmed their selections, EPA has also gained a more refined understanding of the total number of sources that must be included in this information collection. Further adjustments to this ICRs burden estimates result for EPA having more accurately expressed the split between labor and non-labor costs used for the modeling scenario.
