7A <br /> ATTACHMENT 1 Page �9 <br /> . For the continuous operation of stationary mechanical equipment, the average <br /> noise {evels (Leq} in a cumulative period of more than thirty (3Q) minutes in any <br /> hour shafl be (imited to 5U d3A during the daytime (7:OG �ifJ to 9 0:Q0 PfiJi} ariu 45 <br /> dBA during th� nighttime (10:00 PM to 7:00 AM} at the closest residential <br /> prope�ty line. <br /> . For non-continuous, intermittent stationary noise sources, noise levels shali be <br /> limited #o: <br /> - The �a�s� �tai�dat'd plt�s f�v� �5} �8,4 for a cum�lative periad of more than fifkeen <br /> (15} minutes in any hour {i.e. 55 d�A daytime and 50 dBA nighttime); or <br /> - The noise standard plus ten (10) �B for a cumulative period o# mare than five (5) <br /> minutes in any hour (i.e. 60 dBA daytime and 55 dBA nighttime); or <br /> - The n�isz �tandard pl�s fi�een (15; dB for a c�m�alwtive pgrlJd Of mOC� t{�ar� nne <br /> (1} minute in any haur (i.e. 65 dBA daytime and 60 dBA night�ime); or <br /> - The noise standard plus twenty (20) dB or the maximum measured ambient for <br /> any period of time (i.e. 70 dBA daytime and 65 dBA nigh#time). <br /> Finding. The identified noise mitigation measure is feasible and wauid reduce <br /> potentiai noise impacts from #he redevelopmert of the 5equoia Hospi�af <br /> Campus/Prscise Pfan to fess-than-significant level. Mitigation measure NOI-1.1 is <br /> adopted and implementation of this measure would reduce this impact to a less-than- <br /> significant ievel. <br /> C.
