Home My WebLink AboutS-392149N roll W Q Z W J L, TEMPORARY EROSION/SEDIMENTATION CONTROL NOTES: 1. THIS TEMPORARY EROSION/SEDIMENTATION CONTROL (TESC) PLAN DOES NOT CONSTITUTE AN APPROVAL OF PERMANENT ROAD OR DRAINAGE DESIGN (E.G. SIZE AND LOCATION OF ROADS, PIPES, RESTRICTORS, CHANNELS, RETENTION FACILITIES, UTILITIES, ETC.) 2. CONTRACTOR REQUIRED TO SUBMIT TESC AND DEWATERING PLAN TO OWNER AND ENGINEER FOR REVIEW PRIOR TO CONSTRUCTION. 3. CONTRACTOR AND AN ON -SITE REPRESENTATIVE OF OWNER WILL REVIEW THE INSTALLATION, MAINTENANCE AND PERFORMANCE OF THE TESC MEASURES SHOWN ON THE APPROVED PLANS. THE TESC OBSERVER OR PERMITTING AGENCY MAY RECOMMEND ADDITIONAL MEASURES OR CHANGES TO THE TESC PLAN THAT ARE WARRANTED DURING CONSTRUCTION. THE CONTRACTOR AND OBSERVER WILL EXAMINE ALL TESC MEASURES PERIODICALLY DURING THE CONSTRUCTION PERIOD, AND AFTER STORMS HAVING 0.5 INCHES OR MORE OF RAINFALL IN A 24-HOUR PERIOD. THE OBSERVER AND THE PERMITTING AGENCY HAVE THE AUTHORITY TO REQUIRE CORRECTIVE ACTION IN ORDER TO ACHIEVE EROSION CONTROL OBJECTIVES. 4. THE IMPLEMENTATION OF THESE TESC PLANS AND THE CONSTRUCTION, MAINTENANCE, REPLACEMENT, AND UPGRADING OF THESE TESC FACILITIES IS THE RESPONSIBILITY OF THE CONTRACTOR. TESC MEASURES SHALL REMAIN FUNCTIONING AND IN PLACE UNTIL THE SITE HAS BEEN STABILIZED AND THE PERMITTING AGENCY, OWNER OR ENGINEER HAS APPROVED THE REMOVAL OF THE TESC MEASURES. 5. AS CONSTRUCTION PROGRESSES AND UNEXPECTED SEASONAL CONDITIONS DICTATE, ADDITIONAL TESC MEASURES MAY BECOME NECESSARY TO PROTECT ADJACENT PROPERTIES AND TO ENSURE WATER QUALITY FOR SITE RUNOFF. IT SHALL BE THE CONTRACTOR'S RESPONSIBILITY TO ADDRESS DEFICIENT TESC CONDITIONS, AND TO PROVIDE ADDITIONAL FACILITIES, OVER AND ABOVE THE MINIMUM REQUIREMENTS OUTLINED ON THE APPROVED PLANS AS NEEDED. 6. THE TESC FACILITIES SHOWN ON THESE PLANS MUST BE CONSTRUCTED IN CONJUNCTION WITH ALL CLEARING AND GRADING ACTIVITIES, AND IN SUCH A MANNER AS TO INSURE THAT SEDIMENT LADEN WATER DOES NOT ENTER THE DRAINAGE SYSTEM OR VIOLATE APPLICABLE WATER QUALITY STANDARDS. 7. THE TESC FACILITIES SHOWN ON THESE PLANS ARE THE MINIMUM REQUIREMENTS FOR ANTICIPATED SITE CONDITIONS. DURING THE CONSTRUCTION PERIOD, THESE TESC FACILITIES SHALL BE UPGRADED (E.G. ADDITIONAL SUMPS, RELOCATION OF DITCHES AND SILT FENCES, ETC.) AS NEEDED. 8. THE TESC FACILITIES SHALL BE INSPECTED DAILY BY THE CONTRACTOR AND MAINTAINED AS NECESSARY TO ENSURE THEY CONTINUE TO FUNCTION. 9. ANY AREAS OF EXPOSED SOILS, INCLUDING ROADWAY EMBANKMENTS, THAT WILL NOT BE DISTURBED FOR TWO DAYS DURING THE WET SEASON OR SEVEN DAYS DURING THE DRY SEASON SHALL BE IMMEDIATELY STABILIZED WITH APPROVED ESC METHODS (E.G. SEEDING, MULCHING, PLASTIC COVERING, ETC.) 10. ANY AREA NEEDING TESC MEASURE, NOT REQUIRING IMMEDIATE ATTENTION, SHALL BE STABILIZED WITHIN SEVEN (7) DAYS. 11. AT NO TIME SHALL MORE THAN ONE FOOT OF SEDIMENT BE ALLOWED TO ACCUMULATE WITHIN A CATCH BASIN. ALL CATCH BASINS AND CONVEYANCE LINES SHALL BE CLEANED PRIOR TO PAVING. THE CLEANING OPERATION SHALL NOT FLUSH SEDIMENT LADEN WATER INTO THE DOWNSTREAM SYSTEM. 12. WHERE MULCH FOR TEMPORARY EROSION CONTROL IS REQUIRED, IT SHALL BE APPLIED AT A MINIMUM THICKNESS OF 2 TO 3 INCHES. 13. PRIOR TO THE BEGINNING OF THE WET SEASON (OCT. 1), ALL DISTURBED AREAS SHALL BE REVIEWED TO IDENTIFY WHICH AREAS CAN BE STABILIZED IN PREPARATION FOR THE WINTER RAINS. IDENTIFIED AREAS SHOULD BE STABILIZED WITHIN ONE WEEK OF THE BEGINNING OF THE WET SEASON. 14. TEMPORARY EROSION AND SEDIMENT CONTROL (TESC) MEASURES SHALL BE IMPLEMENTED IN ACCORDANCE WITH THE REQUIREMENTS OF THE NPDES CONSTRUCTION STORMWATER GENERAL PERMIT, THE CONSTRUCTION STORMWATER POLLUTION PREVENTION PLAN, ALL OTHER APPLICABLE PERMIT CONDITIONS, AND ALL OTHER APPLICABLE FEDERAL AND STATE LAWS. 15. NOT ALL CONSTRUCTION STORMWATER BMPS ARE SHOWN ON THE TESC DRAWINGS. SEE SWPPP FOR DESCRIPTIONS OF THE BMPS IDENTIFIED IN THE PLAN SHEETS AS WELL AS FOR OTHER APPLICABLE CONSTRUCTION STORMWATER BMPS. 16. TESC MEASURES AND SELECTED BMPS IDENTIFIED ON THE TESC PLAN AND IN THE SWPPP ARE BASED ON INFORMATION AVAILABLE AT THE TIME OF THE DRAWING AND SWPPP DEVELOPMENT. CONTRACTOR'S CERTIFIED EROSION AND SEDIMENT CONTROL LEAD (CESCL) SHALL MODIFY TESC PLAN AND SWPPP AS REQUIRED TO ENSURE THE REQUIREMENTS DESCRIBED IN ITEM 15 ARE MET AT ALL TIMES.
