PRACTICES ACCORDING TO MINIMUM STANDARDS AND SPECIFICATIONS
OF THE LATEST EDITION OF THE VIRGINIA EROSION AND SEDIMENT
CONTROL HANDBOOK AND VIRGINIA REGULATIONS VR 625 -02 -00
EROSION AND SEDIMENT CONTROL REGULATIONS.
THE CONTROLLING EROSION AND SEDIMENT CONTROL AUTHORITY WILL
MAKE A CONTINUING REVIEW AND EVALUATION OF THE METHODS AND
EFFECTIVENESS OF THE EROSION CONTROL PLAN.
PLACE ALL EROSION AND SEDIMENT CONTROL MEASURES PRIOR TO OR
AS THE FIRST STEP IN CLEARING, GRADING, OR LAND DISTURBANCE.
MAINTAIN A COPY OF THE APPROVED EROSION AND SEDIMENT CONTROL
PLAN ON THE SITE AT ALL TIMES.
PRIOR TO COMMENCING LAND- DISTURBING ACTIVITIES IN AREAS OTHER
THAN INDICATED ON THESE PLANS (INCLUDING, BUT NOT LIMITED TO,
OFFSITE BORROW OR WASTE AREA), SUBMIT A SUPPLEMENTARY EROSION
CONTROL PLAN TO THE ARCHITECT/ENGINEER AND THE CONTROLLING
EROSION AND SEDIMENT CONTROL AUTHORITY FOR REVIEW AND
ACCEPTANCE.
PROVIDE ADDITIONAL EROSION CONTROL MEASURES NECESSARY TO
PREVENT EROSION AND SEDIMENTATION AS DETERMINED BY THE
RESPONSIBLE LAND DISTURBER. (MODIFIED NOTE)
ALL DISTURBED AREAS SHALL DRAIN TO APPROVED SEDIMENT CONTROL
MEASURES AT ALL TIMES DURING LAND- DISTURBING ACTIVITIES AND
DURING SITE DEVELOPMENT.
DURING DEWATERING OPERATIONS, PUMP WATER INTO AN APPROVED
FILTERING DEVICE.
INSPECT ALL EROSION CONTROL MEASURES DAILY AND AFTER EACH
RUNOFF- PRODUCING RAINFALL EVENT. MAKE ANY NECESSARY REPAIRS
OR CLEANUP TO MAINTAIN THE EFFECTIVENESS OF THE EROSION
CONTROL DEVICES IMMEDIATELY.
