<br />FACILTIES AT THE END OF EACH WORK DAY DURING THE RAINY SEASON.
<br />10. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TQ CLEAN OUT SEDIMENT BASINS WHENEVER THE
<br />LM OF SEDIMENT REACHES THE SEDIMENT CLEAN OUT LEVEL INDICATED ON THE PIANS
<br />11. IT IS THE RESPONSIBILITIES OF THE CONTRACTOR TO PR07ECT TEMPORARY BORROW AREAS AND/OR
<br />STOCKPILES WITH APPROPRL47E EROSION CONTROL MEASURES 5477SFAC70W TO THE COUNTY ENGINEER.

<br />IS PROHIBITED.
<br />1J. SEN OR SKIRT BETWEEN TRAILER & GRADING 70 PREVENT DIPOSURE TO DRAIN.
<br />14. THE FOLLOWING PUNS ARE ACCURATE FOR EROSION CONTROL PURPOSES ONLY.
<br />15 THE INFORMA71ON ON THIS PUN IS INTENDED TO BE USED AS A GUIDELINE FOR THE CONTRACTOR
<br />AND SUBCONTRACTORS TO COMPLY WITH THE REQUIREMENTS OF THE STATE WATER RESOURCES CONTROL
<br />BOARD. FIELD CONDITIONS MAY NECESSITATE MODIFICATIONS 70 THIS PUN.
<br />16. ANY ON-SITE FUELING SHALL BE LONE AT THE CON7R4C7ORS RISK IN THE DESIGNATED
<br />VEHICLE AWNTENANCE AREA AS A MWIMAM, A SPILL CONTAINMENT KIT SHALL BE ON SITE.
