Section 5
<br />The well redevelopment activities would increase noise level's within the project
<br />area. As shown in Table 74, the well redevelopment activities would exceed the
<br />City's day time noise standard at Receptors 9, 10, 15, 16, 17, 18, and 19. All of
<br />the redevelopment activities would occur during the day when the well
<br />redevelopment activities Would be exempt under the City's Noise ordinance.
<br />Receptors 9, 10, 15, 16, 17, 18, and 19 are school facilities. To minimize noise
<br />impacts the project has incorporated a design feature that would require the well
<br />redevelopment activities to occur when school is not in session. Potential noise
<br />impacts would be less than significant
<br />Alternative 3 Lower Intensity Alternative
<br />Under Alternative 3, one less injection well and a reduced amount of piping
<br />would be constructed. The lower intensity alternative would not include
<br />construction of MBI-2, located in the southwest corner of Centennial Park, or the
<br />pipelines associated with MBI-2. All other portions of Alternative 3 would remain
<br />the saute as the Proposed Project.
<br />Alternative 3 would have the same construction noise impacts as the Proposed
<br />Project for construction Phases 1, 2, 3, 6, and 8. Under Alternative 3, the noise
<br />impacts generated from construction Phases 4, 5 and 7 would be reduced. The
<br />construction noise impacts from Phase 4, 5, and 7 and the operational well
<br />redevelopment activities for Alternative 3 are evaluated below.
<br />Phase 4 Construction Activities
<br />Phase 4 construction activities would involve Well Development at MBI-3. The
<br />noise levels generated during well development are shown in Table 75. The well
<br />development activities would occur 24 hours seven days a week over an 8 day
<br />period. Additionally, test engines utilized in the well development of the
<br />monitoring well would be required to operate 12 to 24 hours a day to simulate
