<br />. <br /> <br />34. During construction, the contractor shall be required to comply with <br />SCAQMD Fugitive Dust Rule 403 to suppress dust generated by <br />construction operations. To ensure compliance with SCAQMD Fugitive <br />Dust Rule 403, grading plans and demolition plans for the proposed <br />project shall reflect the following notes: <br /> <br />. All materials excavated or graded shall be sufficiently watered to <br />prevent excessive amounts of dust. Watering with complete <br />coverage shall occur at least twice daily, once in the late morning and <br />once after work is done for the day. <br /> <br />. All clearing and earthwork activities shall cease during periods of high <br />winds (winds greater than 25 mph averaged). <br /> <br />. Internal roadways and project site entry and exit points shall be <br />cleaned at the end of each day by the project developer. Dust and <br />debris from construction activities that migrates or is carried onto <br />MacArthur Boulevard or Main Street adjacent to the project site <br />shall also be cleaned each day. <br /> <br />. <br /> <br />All material transported off-site shall either be sufficiently watered or <br />securely covered to prevent excessive amounts of dust. Haul trucks <br />leaving the site shall have a minimum freeboard distance of 12- <br />inches. <br /> <br />. <br /> <br />. Construction equipment leaving the project site shall be wheel <br />washed. <br /> <br />. The amount of area disturbed by clearing and earthwork activities <br />shall be minimized at all times. <br /> <br />. Equipment engines shall be maintained in good condition and in <br />proper tune according manufacturer's specifications. <br /> <br />. To the extent feasible, construction equipment shall use alternative <br />clean fuels such as compressed natural gas equipment with <br />oxidation catalysts. If alternative clean fuels are not feasible, <br />gasoline powered construction equipment shall be used. <br /> <br />. Construction equipment operating on diesel fuel shall use <br />particulate filters or low sulfur diesel. <br /> <br />. <br /> <br />To the extent feasible construction operations shall use electricity <br />from power poles in-lieu of temporary diesel or gasoline-powered <br />generators. <br /> <br />. <br /> <br />Exhibit "B" <br />Page 5 of 15 <br />
