<br />12. THE CLEAN/NG OF PAVED STREETS, DURING AND AT THE COMPLETION OF CONS7RUC770N, SHALL BE
<br />PERFORMED WITH MECHANMAL SWEEPERS THE USE OF WA7ER TRUCKS TO '1YASH DOWN" THE STREET
<br />IS PROHIBITED.
<br />13 SEAL OR SKIRT BETWEEN TRAILER & GRADING 70 PREVENT EXPOSURE TO DR41N
<br />14. 7HE FOLLOWING PLANS ARE ACCURATE FOR EROSION CONTROL PURPOSES ONLY.
<br />15. THE INFORMATION ON THIS PLAN /S INTENDED TO BE USED AS A GUIDELINE FOR THE CONTRACTOR
<br />AND SU6CONIAC70RS TO COMPLY WRH THE REQUIREMENTS OF THE STATE WATER RESOURCES CONTROL
<br />BOARD. FIELD CON0I7TONS MAY NECESSIT47E MODIFIC177ONS 70 THIS PLAN.
<br />16. NO ON-SITE FUELING SHALL TAKE PLACE.
<br />'ROLL OR F/!
<br />1. INSPECT AND REPAIR ROLL AFTER EACH STORM EVENT AND REMOVE SEDIMENT WHEN NECESSARY.
<br />2 REMOVED SEDIMENT SHALL BE DEPOSITED 70 AN AREA THAT WILL NOT CONTRIBUTE SEDIMENT
