SIZE AND LOCATION OF RO;\DS. PIPES, RESTRIGTORS, CHANNELS, RETENTION FACIIJTIES, UTILITIES, ETC.) (2) THE IMPLEMENTATION OF THESE TESC PLANS AND THE CONSTRUCTION, MAINTENANCE, REPLACEMENT, AND UPGRADING OF THESE TESC FACILITIES IS THE RESPONSIBILITY OF THE APPLICAN r /TESC SUPERVISOR UNTIL ALL CO~IS mUCTION IS APPROVED. (3) THE BOUNDARiES OF THE CLEARINC LIMITS SHOWN ON THIS PLAN SHALL BE CLEAf,L Y FLAGGED BY A CONTINUOUS LENGTH OF SURVEY TAPE (DR FENCING, IF REQUIRED) PRIOR TO CONSTRUCTION. DURING THE CONSTRUCTION PERIOD, NO DISTUR8ANCE BEYOND THE CLEARING LIMITS SHALL BE PEI~MITTEO. THE CLEARING LIMITS SHALL BE MAINTAINED BY THE APPLICANT /TEeC SUPERVISOR FOR THE DURATION OF CONSTRUCTION. (4) THE lEse FACILITIES SHOWN ON THIS PLAN MUST BE CONSTRUCTED PRIOR TO OF, IN CONJUNCTION WITH ALL CLEARING AND GRADING SO AS TO ENSURE THAT THE TRANSPORT OF SEDIMENT TO SURFACE WATEIIS, DRAINAGE SYSTEMS, AND ADJACENI PROPERTIES IS MINIMIZED. (5) THE rESC FACILITIES ON THIS PLAN ARE THE MINIMUM REQUIREMENTS FOR ANTICIPATED SITE CONDITIONS. DURING THE CONSTRUCIION PERIOD, THESE TESC FACILITIES SHALL B<: UPGRAOW AS ,IEEDED FOR UNEXPECTED STORM EVENTS A,ID MODIFIED TO ACCOUNT FOR CHANGI'IG SITE CONDITIONS (E.G. ADDITIONAL SUMP PUMP, RELOCATIONS OF DITCHES, AND SILT FENCES, ETC.).

(7) ANY AREIIS OF EXPOSED SOILS, INCLUDING ROADWAY EMBANKMENTS, THAT WILL NOT BE DISIURBEO FOR TWO DAYS DURING IHE WET SEASO,I OR SEVEN DAYS DURING THE DRY SEASo'l SHALL BE IMeAEDIATELY STABILIZED WITH THE APPROVED TESC METHODS (E.G. SEEDING, MULCH, PLASTIC COVERING, ETC.) (8) ANY AREA NEEDING TESC MEASURES, NOT IlEQUIFllNG IMMEDIATE ATTENTION, SHALL BE ADDRESSED WITHIN FIFTEEN (15) DAYS (9) THE rESC FACILITIES ON I,IACTIVE SITES SHALL BE INSPECTED AND MAINTAINED A MINIMUM OF ONCE A MONTH OR WITHIN 40 HOURS FOLLOWING A STORM EVENT. (10) AT NO liME SHALL MORE THAN ONE (1) FOOT OF SEDIMENT BE ALLOWED TO ACCUMULATE WITHIN A CATCH BASIN. ALL CATCH BASINS AND CONVEYANCE LINES SHALL BE CLEANED PRIOR TO PAVING. THE CLEANINC OPERATION SHALL NOT FLUSH SEDIMENT-LADEN WATER INTO THE DOWNSTREAM SYSTEM. (II) STABILIZEO CO'ISTRUCTION ENTRANCES AND ROAD SHALL BE INSTALLED AT THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE DURATION OF THE PROJECT.

(12) ANY PERfAANENT RETENTION/DETENTION FACILITY USED AS A TEMPORARY SETILING BASIN SHALL BE MODIFIED WITH THE NECESSARY EROSION CONTROL MEASURES AND SHALL PROVIDE ADEQUATE STORAGE CAPACITY. IF THE PERMANENT FACILITY IS TO FUNCTION ULTIMATELY AS AN I,IFILTRATION SYSTEM, THE TEMPORARY FACILITY MUST BE GRADED SO THAT THE BOTTOM AND SIDES ARE AT LEAST ONE FOOT ABOVE THE FINAL GRADE OF THE PERMANENT FACILITY. (13) WHERE STRAW MULCH FOR TEMPORARY EROSION CONTROL IS REQUIRED, IT SHP.LL BE APPLIED AT A MINIMUM THICKNESS OF 2 TO 3 INCHES. (14) PRIOR TO THE BEGINNING OF THE WET SEASON (OCT. 1), ALL DISTURBED AREAS SHALL BE REVIEWCQ TO IDENTIFY WHiCH ONES CAN BE SEEDED IN PREPARATlml FOR THE WINTEf~ RAINS.
