2. THE CONTACT PERSON RESPONSIBLE FOR EROSION CONTROL IS THE OWNER INDICATED HERE:

_____________________________ 24 HOUR CONTACT TELEPHONE NUMBER: _________________

3. THE CONTRACTOR SHALL BE RESPONSIBLE FOR PROVIDING AN EMERGENCY WORK CREW AT ALL TIMES. THE CONTRACTOR SHALL STOCKPILE THE NECESSARY EROSION CONTROL MATERIALS ON SITE TO FACILITATE RAPID

INSTALLATION OF EROSION CONTROL FACILITIES.

4. THE CONTRACTOR SHALL CONTRACT DE-SILTING FACILITIES AS NECESSARY FOR THE DURATION OF THE PROJECT.

5. THE CONTRACTOR SHALL TAKE MEASURES TO PREVENT RUNOFF OVER THE TOP SLOPES.

6. AFTER RAINSTORM:

A.) THE CONTRACTOR SHALL REMOVE ALL SILT, STANDING WATER, AND DEBRIS FROM

EROSION CONTROL FACILITES;

B.) THE CONTRACTOR SHALL BE RESPONSIBLE TO PREVENT PUBLIC ACCESS INTO AREAS

WHERE STANDING WATER POSES A POTENTIAL HAZARD.

7. IN HIGH WIND AREA THE CONTRACTOR SHALL WATER SPRAY-GRADED AREAS ON A DAILY BASIS TO CONTROL DUST DURING WINDY PERIODS. WHEN NECESSARY, THE CONTRACTOR SHALL TAKE MEASURES TO CONTROL DUST OR WIND BLOWN DEBRIS BY INSTALLING DEBRIS FENCES, ADDITIONAL TRASH ENCLOSURE, CHEMICAL TREATMENT, GEO-MATS, ETC. THE CONTRACTOR SHALL IMPLEMENT LONG-TERM WIND EROSION CONTROL MEASURES FOR ANY AREA THAT IS NOT IMPROVED IN TIMELY MANNER FOLLOWING GRADING. LONG-TERM WIND EROSION CONTROL MEASURES INCLUDE BUT NOT LIMITED TO: PERIMETER WALLS, WIND BARRIERS, SOIL DUST PALLIATIVES, SOIL MATS, HYDRO-SEEDING AND

IRRIGATION SYSTEM.

8. THE CITY ENGINEER RESERVES THE RIGHT TO REQUIRE ALTERNATIVE OR ADDITIONAL EROSION CONTROL FACILITIES, AS HE DEEMS NECESSARY.

B. SEDIMENT CONTROL NOTES

1. SEDIMENT CONTROL BMP'S AREA REQUIRED AT APPROPRIATE LOCATIONS ALONG THE SITE PERIMETER AND AT ALL OPERATIONAL INTERNAL INLETS TO THE STORM DRAIN SYSTEM AT ALL TIMES DURING THE RAINY SEASON.

SEDIMENT CONTROL PRACTICES MAY INCLUDE FILTRATION DEVICES AND BARRIERS (SUCH AS FIBER ROLLS, SILT FENCE, STRAW BALE BARRIERS, AND GRAVEL INLET FILTERS) AND / OR SETTLING DEVICES (SUCH AS SEDIMENT

TRAPS OR BASINS).

2. DURING THE NON-RAINY SEASON, THE DISCHARGER IS RESPONSIBLE FOR ENSURING THAT ADEQUATE SEDIMENT CONTROL MATERIALS ARE AVAILABLE TO CONTROL SEDIMENT DISCHARGES AT THE DOWNGRADE PERIMETER AND OPERATIONAL INLETS IN THE EVENT OF A PREDICTED STORM. THE DISCHARGER SHALL CONSIDER A FULL RANGE OF SEDIMENT CONTROLS, IN ADDITION TO THE CONTROLS LISTED ABOVE, SUCH AS STRAW BALE DIKES, EARTH DIKES, BRUSH BARRIERS, DRAINAGE SWALES, CHECK DAMS, SUBSURFACE DRAINS, SANDBAG DIKES, FIBER ROLLS OR OTHER CONTROLS. AT A MINIMUM, THE DISCHARGER / OPERATOR MUST IMPLEMENT AN EFFECTIVE COMBINATION OF

EROSION AND SEDIMENT CONTROL ON ALL DISTURBED AREAS DURING THE RAINY SEASON.

3. A SEDIMENT BASIN SHALL HAVE A MEANS FOR DEWATERING WITHIN 7 CALENDAR DAYS FOLLOWING A STORM EVENT. SEDIMENT BASINS MAY BE FENCED IF SAFETY (WORKER OR PUBLIC) IS CONCERN. THE OUTFLOW FROM A SEDIMENT BASIN THAT DISCHARGES INTO A NATURAL DRAINAGE SHALL BE PROVIDED WITH OUTLET PROTECTION TO

PREVENT EROSION AND SCOUR OF THE EMBANKMENT AND CHANNEL.

4. THE DISCHARGER MUST CONSIDER ANY ADDITIONAL SITE-SPECIFIC AND SEASONAL CONDITIONS WHEN SELECTING

AND DESIGNING SEDIMENT CONTROL BMP'S

5. DISCHARGER MUST REDUCE THE TRACKING OF SEDIMENT ONTO PUBLIC OR PRIVATE ROADS AT ALL TIMES. THESE PUBLIC AND PRIVATE ROADS SHALL BE INSPECTED AND CLEANED AS NECESSARY. ROAD CLEANING BMP'S SHALL BE USED AS NECESSARY AND WILL NOT RELY ON THE WASHING OF ACCUMULATED SEDIMENT OR SILT INTO THE STORM

DRAIN SYSTEM.
