ALL4’s: Is That Your Final Answer?
Posted: February 28th, 2011Author: All4 Staff
Last Month’s Answer and Winner:
We received several responses to our January edition of “Is That Your Final Answer” and Robert Wells was the first to provide the answer for which we were looking. In order to trigger Nonattainment New Source Review (NNSR), a source must first be major for the nonattainment pollutant. It does not matter if a source is major for another pollutant; the source must be major for the NNSR pollutant. There where other responses that could also apply to our question, but these responses did not highlight the key applicability test for NNSR. Thanks for everyone’s participation and good luck with this month’s question.
On a cold and snowy February morning, a young scientist here at ALL4 came up to an older scientist here at ALL4 with a question concerning New Source Performance Standards (NSPS) and greenhouse gases (GHGs). “I don’t quite follow,” our young friend asked, “why and how can electric utility steam generating units (EGUs) be regulated under the NSPS with a performance standard as well as an emission guideline.” The older scientist leaned back in his chair and took a sip of his hot tea. “Performance standards and emission guidelines have for years existed for many other source categories, just check out 40 CFR Part 60. But most people don’t take the time to know the simple difference between the two.” And after 60 seconds the young scientist said, “I understand completely, it makes sense.” What was explained to the younger scientist?
