All noise-producing project equipment and vehicles using <br /> internal combustion engines shall be equipped with <br /> mufflers and air-inlet silencers, where appropriate, in good <br /> operating condition that meet or exceed original factory <br /> specifications. Mobile or fixed "package" equipment (e.g., <br /> arc-welders, air compressors) shall be equipped with <br /> shrouds and noise control features that are readily available <br /> for that type of equipment. <br />b. All mobile or fixed noise-producing equipment used on the <br /> project, which is regulated for noise output by a local, state, <br /> or federal agency, shall comply with such regulations while <br /> in the course of project activity. <br />c. Material stockpiles and mobile equipment staging, parking, <br /> and maintenance areas shall be located as far as practicable <br /> from noise-sensitive receptors. <br />d. Locating fixed noise generating equipment as far from <br /> noise sensitive land uses as practical. <br />e. The hours of construction, including noisy maintenance <br />activities, shall be restricted to the periods and days <br />permitted by the City of Santa Ana Noise Ordinance. <br />f. Limit the loudest construction activities, such as concrete <br />breaking and jack hammering, to the middle of the day <br />when the sensitivity to such noises will be at its lowest. <br />g. Noise producing signals, including horns, whistles, alarms, <br />and bells shall be used for safety warning purposes only. <br />h. No project related public address or music systems shall be <br />audible at any adjacent receptor. <br />i. If complaints arise, the contractor shall initiate a <br />construction noise-monitoring plan to ensure the <br />construction noise levels at the nearest noise sensitive land <br />uses are within the limits of the noise ordinance. <br />j. Use of temporary noise barriers shall be considered where <br />project activities and equipment is unavoidably close to <br />noise sensitive receptors. <br />k. Use of on-site trailers and containers as temporary barriers <br />between any fixed construction noise source and nearby <br />sensitive receptors. <br />56 <br />Initial Study/Mitigated Negative Declaration July 2008 <br />Harbor Medical and Retail Center ~ ~ A ~ ~ ^ <br />
