The borehole drilling <br />activities would occur 24 hours seven days a week over an 8 day period. <br />Additionally, test engines utilized in the well development of M131-5 would be <br />required to operate 12 to 24 hours a day to simulate well operations. The <br />duration of engine testing would be 6 days for 12 hours and 1 day for 24 hours. <br />Table 52: MBI-2 Borehole Drilling and MBI-3 Well Development Day Time <br />Noise Levels <br />'Receiver <br />Description <br />Extatirig <br />Ex'W410 + <br />Increase ^ <br />Threshold <br />Constroction <br />1 <br />Multi Family west Santa <br />41,8 <br />60.6 <br />8.8 <br />55.0 <br />Ana River <br />2 <br />Multi Family west Santa <br />61.9 <br />62,1 <br />02 <br />84.9 <br />Ana River <br />3 <br />Single Family north <br />65.6 <br />65.7 <br />0 1 <br />68.6 <br />Edinger Ave, <br />4 <br />Single Family north <br />64.4 <br />64.7 <br />0,3 <br />67.4 <br />Edinger Ave. <br />5 <br />Single Family north <br />643 <br />64.8 <br />0,11 <br />67.7 <br />Edinger Ave. <br />6 <br />Single family north <br />713 <br />71.7 <br />On <br />74.7 <br />Edinger Ave. <br />7 <br />Single family north <br />67.6 <br />67.6 <br />0,0 <br />70.6 <br />Edinger Ave, <br />8 <br />Multi Family north <br />66.2 <br />66.2 <br />0.0 <br />69.2 <br />Edinger Ave. <br />9 <br />North Centennial <br />59.5 <br />59.9 <br />0.4 <br />62.5 <br />Education Center <br />10 <br />Southeast Centennial <br />54.8 <br />54.8 <br />M <br />55.0 <br />Education Center <br />11 <br />Single Family east <br />71,8 <br />71.8 <br />0.0 <br />74.8 <br />Fairview Street <br />12 <br />Single Family east <br />71.3 <br />71.3 <br />0,0 <br />74.3 <br />Mid Basin Centennial Park Jjg3dnj " Project Final EIR 5-174 <br />
