FUNCTIONAL AND IN PLACE UNTIL THEY HAVE SERVED THEIR INTENDED

PURPOSE AND THE WORK AREA HAS BEEN PERMANENTLY PROTECTED AND

STABILIZED. CONTRACTOR TO RETURN TO SITE AND REMOVE ALL ESC

MEASURES WHEN NO LONGER NEEDED. RESTORE ALL AREAS DISTURBED BY

REMOVAL OF THE ESC MEASURES. REMOVED ESC MEASURES SHALL BECOME

PROPERTY OF THE CONTRACTOR.

6. THE EROSION AND SEDIMENTATION CONTROL PLANS SHOWN ARE FOR

GENERAL GUIDANCE PURPOSES ONLY. IMPLEMENTATION OF THE ESC PLAN

AND THE CONSTRUCTION, MAINTENANCE, REPLACEMENT, AND UPGRADING OF

THE CONSTRUCTION SITE, ENTER THE DRAINAGE SYSTEM, BE TRACKED ON

ROADWAYS, OR VIOLATE APPLICABLE WATER STANDARDS.

8. INSPECT ESC MEASURES DAILY AND MAINTAIN AS NECESSARY TO ENSURE

THEIR CONTINUED FUNCTIONING.
