meteorological and demographic variations exist between neighboring states that may not warrant equivalent monitoring seasons. The EPA notes that regional consistency was thought of, but only necessary for a couple of states the place little information had been out there and the neighboring states had extra obtainable knowledge and a adequate number of days that have been ≥ 0.060 ppm to support the proposed O3 season modifications. Regional consistency was not essential for different states. Several commenters had concerns about the extra vintage dog westie bath soap wash your paws poster value and assets wanted to expand the O3 monitoring seasons. There was some disagreement with the EPA’s whole annual average value estimate of $230,000 which took into account the number of O3 displays already working year-spherical across the country. Commenters noted particularly that the proposed extension of required monitoring seasons would enhance operational prices and doubtlessly influence the assets obtainable for different monitoring efforts.
The added cost of working O3 displays over an extended period was famous by some commenters, referencing each the cost of employees to operate the monitors, as well as the additional put on and tear those O3 monitors would expertise over a longer operational period. They famous that extending their required monitoring season by adding the month of March would improve staffing necessities for monitor operation and high quality assurance. They additionally noted that the life expectancy of equipment would be lowered as a result of increased put on and tear. The EPA acknowledges that operational prices for O3 monitoring networks will incrementally improve in states the place required seasons have been lengthened. We encourage monitoring businesses to evaluate available expertise and operational procedures to institute practices that might probably cut back such costs, such because the automation of high quality management and calibration checks and remote entry to judge monitor operations. As noted earlier, all states operated at least a portion of their O3 monitoring community outdoors of the required O3 season during the data period and reported the data to AQS. In addition, many states are operating greater than the minimum variety of monitors required to support the essential monitoring goals described in forty CFR part 58, Appendix D. Some states have a large percentage of their total O3 displays working outside the currently-required O3 season and some states have a small proportion. In conditions the place states are already operating a large number of their O3 monitors outdoors their current O3 season, the actual cost enhance might be less. In circumstances where states have a small number of displays operating outside their current O3 season, in addition to automation and distant access, these states might examine with their Regional Administrator the method in forty CFR half 58.14 for reducing the whole variety of working screens that are above the quantity required by 40 CFR, half 58, appendix D to offset the price of extending the O3 monitoring season of their state. Certain logistical complexities had been noted if longer seasons had been required, including website entry during winter and the problem of getting the monitoring gear ready in time. Four states famous considerations with operator security and anticipated their incapability to access sites due to early spring snowfall. The EPA agrees that site entry could be a problem depending on climate circumstances and notes that specific site monitoring season deviations could also be acceptable. We counsel that this be addressed through the monitoring season waiver course of with the EPA Regional Administrator.
