There will be no will increase of emissions from the Valley Power Plant, which would seem to be of distinct worry to the commenter. The facility has, in truth, observed emissions reductions from new combustion modifications that have been mounted as a final result of this rule. Other than the reality that include-on controls are remaining put on the Enjoyable Prairie Power Plant that are not staying put on the Valley Electricity Plant, Get started Printed Page 64159 it is unclear why the commenter thinks there is a circumstance of environmental injustice.
Table 1 displays the ozone style and design values for numerous displays in the southeast portion of Wisconsin. All of the screens are meeting the 1997 eight-hour ozone conventional of . 08 ppm.
In reality, all of the monitors in Wisconsin are currently conference the 1997 8-hour ozone common. The keep an eye on that is closest to the Valley Plant, the 16th St. Wellbeing Centre keep an eye on, has the lowest monitored ozone values in the southeast Wisconsin spot. It is around 1. one miles to the south-southwest of the Valley Plant, the plant of greatest problem to the commenter.
For comparison, the keep track of closest to the Pleasurable Prairie Plant has the highest values recorded in the southeast Wisconsin location. The checking details do not show that ozone is a issue in the speedy vicinity of the Valley Power Plant and that increased controls should really be positioned on the Valley Ability Plant. It is not constantly the circumstance that reductions will gain the speedy space where they are created. It is, however, very clear that ozone and its precursors are likely to travel from south to north together plantidentification.co the Lake Michigan shoreline in Wisconsin. The substantial ranges of ozone monitored in Kenosha County at the Enjoyable Prairie monitor are most likely thanks in section to emissions from sources in the Chicago area.
Similarly, if reductions are built at the Enjoyable Prairie Electrical power Plant, the advantages will be knowledgeable downwind in the Milwaukee area ( i. e. , in close proximity to the Valley Electrical power Plant). Equally, reductions built at the Valley Electricity Plant will very likely lessen ozone downwind. The closest observe that would be in a position to validate this is the WDNR’s Regional Headquarters (WDNR SER HQTRS) monitor that is about 2. 2 miles to the north-northeast of the Valley Power Plant. Monitor 2004-2006 Design and style benefit (ppm) 2005-2007 Style value (ppm) 2006-2008 Style benefit (ppm) 2007-2009 Design price (ppm) Pleasant Prairie . 083 . 085 . 078 . 076 Well being Centre . 068 . 070 . 063 . 064 WDNR SER HQTRS . 074 . 077 . 068 . 068. The commenter also raises NO 2 concentrations as a issue.
As the commenter states in the comment submitted, “The Milwaukee County style and design price for 2007-2009 is 47 ppb or 89 μg/m 3 . ” Having said that, 47 ppb is nicely beneath the Countrywide Ambient Air Excellent Regular (NAAQS) for NO 2 , which is a hundred ppb.
The NAAQS are founded to guard human wellness and the ecosystem. With this in intellect, displays to establish if regions are conference or violating the NAAQS are necessary in and all-around spots in which people are living, and these screens are normally placed at floor-level where individuals are respiration the ambient air. The commenter statements to have modeled a violation of the NO two normal, but the commenter’s modeling procedure is flawed. The commenter takes NO two emissions concentrations from the Valley Energy Plant stack and adds them to background concentrations to get a modeled ambient focus that exhibits a violation of the NO two NAAQS.
