HHI Trucking & Supply, Inc. v. Borough Council of Borough of Oakmont, 990 A.2d 152, 163 (Pa.Cmwlth.,2010)

ZONING: Conditional use conditions for cement plant near residential homes. Case requires that zoning ordinance define the terms “objectionable” or “acceptable” sound levels with adequate specificity to allow for measurement or analysis.  “The terms ‘objectionable’ and ‘acceptable’ are not defined, and the Zoning Ordinance does not specify which ANSI standard should be used to measure the sound pressure level. In the absence of such specificity, Borough Council’s required study is impossible of execution and, as such, unreasonable.” [163]
