FROM RISER IN SKIMMER BASIN AND INSTALL PERMANENT STONE BAFFLE. DISPOSE
OF ALL SEDIMENT ACCORDING TO NCDEQ REQUIREMENTS.
32. STABILIZE ANY AREAS DISTURBED BY REMOVAL OF DEVICES IMMEDIATELY.
MAINTENANCE SCHEDULE
1. IN GENERAL, ALL EROSION AND SEDIMENT CONTROL MEASURES WILL

SHALL BE REPAIRED BY THE CLOSE OF DAY. MAINTENANCE SHALL
CONTINUE THROUGHOUT THE LENGTH OF THE PROJECT.
2. SILT REMOVAL AND SEDIMENT CLEAN -OUT FROM EROSION AND
SEDIMENT CONTROL ITEMS SHALL BE PERFORMED IN ACCORDANCE
WITH THE FOLLOWING:
SILT FENCES AND DROP INLET PROTECTION WILL BE CHECKED
REGULARLY AND WILL BE CLEANED OUT WHEN THE CAPACITY, HEIGHT
OR DEPTH HAS BEEN REDUCED BY 50%.
3. ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO SEE THAT A GOOD STAND IS
MAINTAINED. AREAS SHALL BE FERTILIZED AND
RE -SEEDED AS NEEDED.
4. STREETS SHALL BE KEPT CLEAN OF MUD AND SILT. PERIODIC
CLEANING OF STREETS SHALL BE PERFORMED.
5. OVERLAND DRAINAGE SHALL NOT CONTAMINATE ROADWAY PAVEMENT SURF ACES.
6. THE E&SC INSPECTOR SHALL HAVE THE AUTHORITY TO ADD OR DELETE EROSION AND
SEDIMENT CONTROLS AS NEEDED IN THE FIELD AS CONDITIONS WARRANT. IN ADDITION, NO
EROSION AND SEDIMENT CONTROL MEASURES MAY BE REMOVED WITHOUT PRIOR
APPROVAL OF THE INSPECTOR.
GENERAL EROSION AND SEDIMENT CONTROL NOTES
1. EXCESS EXCAVATION DISPOSED OF OFF SITE SHALL BE DISPOSED OF IN ACCORDANCE
WITH NCDEQ STANDARDS.
2. EROSION AND SEDIMENT CONTROLS SHALL REMAIN UNTIL THE
DISTURBED AREA IS STABILIZED AND SHALL BE MAINTAINED SO THAT SEDIMENT CARRYING
RUNOFF FROM THE SITE WILL NOT ENTER STORM DRAINAGE FACILITIES
3, IN THE EVENT A CONTRACTOR DUMPS, DISCHARGES OR SPILLS ANY OIL OR CHEMICAL
THAT REACHES, OR HAS THE POTENTIAL TO REACH, A WATERWAY, THE CONTRACTOR SHALL
IMMEDIATELY NOTIFY ALL APPROPRIATE JURISDICTIONAL STATE, FEDERAL. AND CITY
AGENCIES AND SHALL TAKE IMMEDIATE ACTIONS FOR CONTAINMENT AND REMOVAL OF THE
OIL OR CHEMICAL.
4. CONTRACTOR WILL BE REQUIRED TO MAINTAIN THE SELF -INSPECTION FORMS AND MUST
