One type of criteria focuses on the relative change in noise levels and the other <br /> type focuses on the absolute value of the noise generated by project noise sources. The City of <br /> Stockton has not adopted its own significance criteria to assess the significance of relative <br /> increases in noise levels from existing conditions.With respect to the overall DNL at adjacent <br /> residences,City staff have indicated that there is no limitations on the increase in the overall <br /> Stockton Scavenger Transfer Station Expansion III.D.8 ESA 1990190 <br />
