IALL REQUIRED SED|WENTATl(}N/ERU80N FACILITIES MUST BE CONSTRUCTED AND IN OPERATION PRIOR TO LAND CLEARING AND/OR OTHER CONSTRUCTION TO INSURE THAT SEDIMENT LADEN WATER DOES NOT ENTER THE NATURAL DRAINAGE SYSTEM. ALL EROSION AND SEDIMENT FACILITIES SHALL BE MAINTAINED IN A SATISFACTORY CONDITION UNTIL SUCH TIME THAT CLEARING AND/OR CONSTRUCTION IS COMPLETED AND POTENTIAL FOR ON -SITE EROSION HAS Pf\S5EO. THE IMPLEMENTATION, MAINTENANCE, REPLACEMENT AND ADDITIONS TO ERO3|0N/S[D|MENTATlON CONTROL SYSTEMS SHALL BE THE RESPONSIBILITY OF THE PERk4|TTEE. 4.THE EROSION AND SEDIMENTATION CONTROL SYSTEMS ON THIS DRAWING ARE INTENDED TO BE k4|N|KJUkJ REQUIREMENTS TO MEET ANTICIPATED SITE CONDITIONS. AS CONSTRUCTION PROGRESSES AND UNEXPECTED OR SEASONAL CONDITIONS DICTATE, THE P[RM|TTEE SHALL ANTICIPATE THAT MORE EROSION AND SEDIMENTATION CONTROL FACILITIES WILL BE NECESSARY TO INSURE COMPLETE SILTATION CONTROL ON THE PROPOSED SITE. DURING THE COURSE OF CONSTRUCTION, /T SHALL BE THE OBLIGATION AND RESPONSIBILITY OF THE P[RM|TTEE TO ADDRESS ANY NEW CONDITIONS THAT WAY BE CREATED BY THIS ACTIVITIES AND TO PROVIDED ADDITIONAL FACILITIES, OVER AND ABOVE MINIMUM REQUIREMENTS, AS MAY BE NEEDED TO PROTECT ADJACENT PROPERTIES AND WATER QUALITY OF THE RECEIVING DRAINAGE SYSTEM. 5,APPR0VAL OF THIS PLAN IS FOR EROS|ON/SED/k4ENTAT/ON CONTROL ONLY. IT DOES NOT CONSTITUTE AN APPROVAL OF STORM DRAINAGE DES|GN, SIZE NOR LOCATION OF PIPES, RESTR|CTORS . CHANNELS. OR RETENTION FACILITIES. S.DUR|NG THE TIME PERIOD OF NOVEWBER 1 THROUGH MARCH 31, ALL PROJECT DISTURBED SOIL AREAS GREATER THAN 5,000 SQUARE FEET, THAT ARE LEFT UNM0RKED FOR MORE THAN TWELVE '12\ HOURS' SHALL BE COVERED BY MULCH, SODDING, OR PLASTIC COVERING. 7.|N ANY AREA WHICH HAS BEEN STRIPPED OF VEGETATION AND WHERE FURTHER WORK IS ANDC|PATED FOR PERIOD OF 30 DAYS OR K40RE, ALL DISTURBED AREAS MUST BE IMMEDIATELY STABILIZED WITH MULCHING, GRASS PLANTING OR OTHER APPROVED EROSION CONTROL TREATMENT APPLICABLE TO THE TIME OF YEAR /N QUESTION. GRASS SEEDING ALONE WILL BE ACCEPTABLE ONLY DUR!NG THE MONTHS OF APR|L THROUGH SEPTEMBER INCLUSIVE. SEEDING MAY PR()CEED, HOWEVER.
