If we start including decibel levels here, and they're high, and you get a complaint, and a citizen is complaining that the noise is too loud, then if the agency goes in and determines that in fact the decibel levels are within the regulation, the agency's hands are tied; they can't take any action that potentially would allow the agency to correct whatever is causing the problem that the complaint is about. Our concern is that you don't want to be setting thresholds, because you notice these decibel levels are fairly high; once you put something in writing--once you put a law in place--the agency has to live by that law, and that's how it became subject to challenge in 2000.
Give it the flexibility. It may be that an activity is within the decibel levels, but there's still action that the agency can prescribe to try to minimize the impact on the complainant.
That's it. If you start putting limits, the agency has to abide by those limits.
