6. CALL FOR ON -SITE INSPECTION BY NCDEQ INSPECTOR. WHEN APPROVED, CONTRACTOR MAY THEN BEGIN CLEARING
AND GRUBBING THE REMAINING PORTIONS OF AREA.
7. MAINTAIN EROSION CONTROL DEVICES AS NECESSARY.
8. STABILIZE SITE AS AREAS ARE BROUGHT TO FINISH GRADE. REFER TO DETAIL SHEET C-5.1 FOR SEEDING.
10. CONTRACTOR TO COORDINATE WITH EROSION CONTROL INSPECTOR PRIOR TO REMOVAL OF ANY EROSION CONTROL
MEASURES.
11. ONCE SITE IS STABILIZED, SEDIMENT BASIN ST-2 MAY BE CONVERTED TO SAND FLITER SF-1 PER SHEET C-6.0.
EROSION CONTROL NOTES:
