G.S. 113A-57(2). THE PERSON WHO PERFORMS THE INSPECTION SHALL
MAINTAIN AND MAKE AVAILABLE A RECORD OF THE INSPECTION AT THE
SITE OF THE LAND -DISTURBING ACTIVITY. THE RECORD SHALL SET OUT
ANY SIGNIFICANT DEVIATION FROM THE APPROVED EROSION CONTROL
PLAN, IDENTIFYANY MEASURES THAT MAY BE REQUIRED TO CORRECT THE
DEVIATION, AND DOCUMENT THE COMPLETION OF THOSE MEASURES. THE
RECORD SHALL BE MAINTAINED UNTIL PERMANENT GROUND COVER HAS
BEEN ESTABLISHED AS REQUIRED BY THE APPROVED EROSION AND
SEDIMENTATION CONTROL PLAN. THE INSPECTIONS REQUIRED BY THIS
SUBSECTION SHALL BE IN ADDITION TO INSPECTIONS REQUIRE BY G.S.

GENERAL NOTES:
PURSUANT TO G.S. 133 A57(2), THE ANGLE FOR GRADED SLOPES AND FILLS
SHALL BE NO GREATER THAN THE ANGLE THAT CAN BE RETAINED BY
VEGETATIVE COVER OR OTHER ADEQUATE EROSION -CONTROL DEVICES OR
STRUCTURES.
IN ANY EVENT, SLOPES LEFT EXPOSED WILL, WITHIN 7 OR 14 CALENDAR
DAYS OF COMPLETION OF ANY PHASE OF GRADING, BE PLANTED OR
OTHERWISE PROVIDED WITH TEMPORARY GROUND COVER, DEVICES, OR
STRUCTURES SUFFICIENT TO RESTRAIN EROSION. PERMANENT
GROUNDCOVER WILL BE PROVIDED FOR ALL DISTURBED AREAS WITHIN 15
WORKING DAYS OR NO MORE THAN 90 CALENDER DAYS (WHICHEVER IS
SHORTER) FOLLOWING COMPLETION OF CONSTRUCTION,
PURSUANT TO G.S. 113A-57(3), PROVISIONS FOR PERMANENT

INSPECT BAFFLES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY
REQUIRED REPAIRS IMMEDIATELY.
BE SURE TO MAINTAIN ACCESS TO THE BAFFLES. SHOULD THE FABRIC OFA BAFFLE
COLLAPSE, TEAR DECOMPOSE OR BECOME INEFFECTIVE, REPLACE IT PROMPTLY.
REMOVE SEDIMENT DEPOSITS WHEN IT REACHED HALF FULL TO PROVIDE ADEQUATE
STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE PROESSURE ON THE BAFFLES.
TAKE CARE TO AVOID DAMAGING THE BAFFLES DURING CLEANOUT. SEDIMENT DEPTH
SHOULD NEVER EXCEED HALF THE DESIGNED STORAGE DEPTH.
AFTER CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY STABILIZED, REMOVE ALL
BAFFLE MATERIALS AND UNSTABLE SEDIMENT DEPOSITS, BRING THE AREA TO GRADE,
AND STABILIZE IT.
