<br />THE NOTES AND DETAILS PROVIDED ON THIS SHEET ILLUSTRATE SOME OF THE MOST
<br />COMMON TEMPORARY EROSION/SILTATION CONTROL BEST MANAGEMENT PRACTICES
<br />(BMPs). ALTHOUGH SOME MEASURES SHOWN HERE MAY NOT BE SPECIFIED IN THE T.E.S.C.
<br />PLAN FOR THIS PROJECT, THE DETAILS ARE PROVIDED FOR FUTURE REFERENCE SHOULD
<br />SITE CONDITIONS REQUIRE ADDITIONAL MEASURES BEYOND THOSE SPECIFIED.
<br />APPROPRIATE RESPONSES TO UNANTICIPATED SITE CONDITIONS MAY INCLUDE, BUT ARE
<br />NOT LIMITED TO, THE FOLLOWING ADDITIONAL BMPs:
<br />• STRAW MULCH
<br />• TEMPORARY DITCHES, SWALES, DIKES OR BASINS
<br />• JUTE OR SYNTHETIC MATTING, EITHER GENERIC OR PROPRIETARY
<br />• SLOPE SCARIFICATION OR TERRACING
<br />• ANCHORED PLASTIC SHEETING
<br />• MULCH, BRUSH OR GRAVEL FILTER BERMS
<br />• DUST CONTROL
<br />• TIRE WASH STATIONS
<br />• SODDING
<br />• ROCK CHECK DAMS
<br />SUCH MEASURES SHALL BE SELECTED BY THE CONTRACTOR IN CONSULTATION WITH THE
<br />CITY INSPECTOR AND THE CESCL, AND SHALL BE INSTALLED PER MANUFACTURER'S
<br />SPECIFICATIONS, ENGINEER'S DESIGN OR STANDARD CONSTRUCTION INDUSTRY
<br />PRACTICE AS THE SITUATION DICTATES.
<br />1. THE TEMPORARY EROSION/SEDIMENTATION CONTROL FACILITIES SHALL BE
<br />CONSTRUCTED PRIOR TO ANY GRADING OR LAND CLEARING IN ACCORDANCE WITH
<br />THE APPROVED TEMPORARY EROSION/SEDIMENTATION CONTROL PLAN. THESE
<br />FACILITIES MUST BE SATISFACTORILY MAINTAINED UNTIL CONSTRUCTION AND
<br />LANDSCAPING IS COMPLETED AND THE POTENTIAL FOR ON -SITE EROSION HAS PASSED.
<br />2. NONCOMPLIANCE WITH THE EROSION CONTROL REQUIREMENTS, WATER QUALITY
<br />REQUIREMENTS, AND/OR CLEARING LIMITS MAY RESULT IN REVOCATION OF PROJECT
<br />PERMITS OR PLAN APPROVAL, FINES AND BOND FORECLOSURES.
<br />3. THE T.E.S.C. FACILITIES SHOWN ON THIS PLAN ARE THE MINIMUM REQUIREMENTS FOR
<br />ANTICIPATED SITE CONDITIONS. THE CONTRACTOR SHALL BE RESPONSIBLE FOR
<br />PROVIDING IMPROVED OR MODIFIED FACILITIES AS NECESSARY TO MAINTAIN RUNOFF
<br />WATER QUALITY DURING AND AFTER SIGNIFICANT STORM EVENTS AND TO ADDRESS
<br />THE ACTUAL SITE AND SOILS CONDITIONS ENCOUNTERED.
<br />4. CONTRACTOR SHALL MAINTAIN ON SITE AT ALL TIMES SUFFICIENT QUANTITIES OF
<br />EROSION CONTROL MATERIALS TO COVER ALL EXPOSED SOIL IN THE EVENT OF
<br />UNANTICIPATED WEATHER CONDITIONS. CONTRACTOR MAY CONSIDER PHASING
<br />GRADING ON LARGE SITES TO MINIMIZE BARE SOIL EXPOSURE.
<br />5. THE IMPLEMENTATION OF THESE TESC PLANS AND THE CONSTRUCTION,
<br />MAINTENANCE, REPLACEMENT, AND UPGRADING OF THESE T.E.S.C. FACILITIES IS THE
<br />RESPONSIBILITY OF THE APPLICANT/CONTRACTOR UNTIL ALL CONSTRUCTION IS
<br />APPROVED. BARE AND/OR DISTURBED SOILS SHALL REMAIN UNCOVERED FOR NO
<br />MORE THAN 2 DAYS FROM OCTOBER 1 THROUGH APRIL 30, AND FOR NO MORE THAN 7
<br />DAYS FROM MAY 1 THROUGH SEPTEMBER 30. STABILIZE WITH APPROVED T.E.S.C.
<br />METHODS (E.G. SEEDING, MULCHING, NETTING, EROSION BLANKETS, PLASTIC
<br />COVERING, ETC.). SOIL STOCKPILES SHALL BE STABILIZED WITHIN 24 HOURS.
<br />6. WHERE STRAW MULCH FOR TEMPORARY EROSION CONTROL IS REQUIRED, IT SHALL BE
<br />APPLIED AT A MINIMUM THICKNESS OF TWO INCHES.
<br />7. 7. ANY AREA NEEDING T.E.S.C. MEASURES, NOT REQUIRING IMMEDIATE ATTENTION,
<br />SHALL BE ADDRESSED WITHIN FIFTEEN (15) DAYS.

<br />MINIMUM OF ONCE A MONTH OR WITHIN THE 48 HOURS FOLLOWING A STORM EVENT.
<br />9. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED
<br />WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION IS ACHIEVED OR AFTER THE
<br />TEMPORARY BMPs ARE NO LONGER NEEDED. TRAPPED SEDIMENT SHALL BE REMOVED
<br />OR STABILIZED ON SITE. DISTURBED SOIL AREAS RESULTING FROM REMOVAL SHALL BE
<br />PERMANENTLY STABILIZED.
<br />10. CONTRACTOR SHALL USE INDUSTRY BEST MANAGEMENT PRACTICES TO PREVENT
<br />PETROLEUM PRODUCTS, FERTILIZERS, CONCRETE BY-PRODUCTS AND OTHER
<br />POLLUTANTS FROM ENTERING OFF -SITE DRAINAGE COURSES. SLASH PILES AND
<br />OTHER SOLID WASTE SHALL BE DISPOSED OF IN ACCORDANCE WITH ALL APPLICABLE
<br />LOCAL REGULATIONS.
<br />11. WASTEWATER FROM PROJECT ACTIVITIES AND DE -WATERING SHALL BE ROUTED TO
<br />AN UPLAND AREA FOR REMOVAL OF FINE SEDIMENTS AND OTHER CONTAMINANTS.
<br />ONLY CLEAN, UNPOLLUTED WATER SHALL LEAVE THE SITE.
<br />12. THE CONTRACTOR SHALL KEEP OFF -SITE STREETS CLEAN AT ALL TIMES BY SWEEPING.
<br />WASHING OF THESE STREETS WILL NOT BE ALLOWED WITHOUT PRIOR CITY OF
<br />EVERETT APPROVAL.
<br />CONTRACTOR RESPONSIBILITY FOR
<br />EROSION/SILTATION CONTROL
<br />IT IS THE INTENT OF THIS TEMPORARY EROSION AND SILTATION CONTROL PLAN THAT STORM
<br />WATER RUNOFF BE CONTROLLED AT ALL TIMES TO PREVENT SOIL EROSION AND TO MAINTAIN
<br />WATER QUALITY. ANY AND ALL MEASURES NECESSARY TO DO SO SHALL BE EMPLOYED BY THE
<br />CONTRACTOR.
<br />1. REGARDLESS OF SITE, WEATHER, SOIL OR OTHER CONDITIONS, THE CONTRACTOR SHALL BE
<br />FULLY RESPONSIBLE FOR ENSURING THAT EROSION DOES NOT OCCUR ON THE SITE AND
<br />THAT POLLUTED OR SILT -LADEN RUNOFF DOES NOT LEAVE THE SITE OR ENTER INTO ANY
<br />CREEK, STREAM, WETLAND OR WATER BODY ON OR OFF THE SITE.
<br />2. BEYOND THE MINIMUM REQUIREMENTS SHOWN ON THIS PLAN, THE CONTRACTOR SHALL BE
<br />RESPONSIBLE FOR SELECTING AND IMPLEMENTING APPROPRIATE METHODS, "BEST
<br />MANAGEMENT PRACTICES" (BMPs), FOR STORM WATER TREATMENT AND CONTROL THAT
<br />MEET THE REQUIREMENTS OF BOTH THE WASHINGTON STATE DEPARTMENT OF ECOLOGY
<br />AND CITY OF EVERETT.
<br />3. THE CONTRACTOR SHALL REPORT ALL WATER QUALITY CONCERNS AND ACTIVITIES TO THE
<br />CERTIFIED EROSION AND SEDIMENT CONTROL LEAD (C.E.S.C.L.) AND TO CITY OF EVERETT. IN
<br />THE EVENT THAT THE INSTALLED WATER QUALITY CONTROL MEASURES ARE INEFFECTIVE AT
<br />CONTROLLING EROSION AND SILTATION, THE CONTRACTOR SHALL IMMEDIATELY REPORT TO
<br />AND CONSULT WITH THE C.E.S.C.L. TO FIND AN APPROPRIATE REMEDY. ALL CONSTRUCTION
<br />ACTIVITIES, WITH THE EXCEPTION OF EROSION AND SILTATION CONTROL MEASURES, SHALL
<br />CEASE UNTIL SUCH TIME AS THE WATER QUALITY IS BROUGHT INTO COMPLIANCE WITH D.O.E.
<br />AND CITY OF EVERETT REQUIREMENTS.
<br />4. THE CONTRACTOR SHALL BE RESPONSIBLE FOR MONITORING WEATHER FORECASTS AND
<br />ANTICIPATING STORM ACTIVITY AND SHALL SCHEDULE ALL PROJECT ACTIVITIES IN
<br />ANTICIPATION OF THE WEATHER.
<br />5. ALL SUPPLIES AND MATERIALS NECESSARY FOR IMPLEMENTING BMPs SHALL BE STORED ON
<br />SITE AND SHALL BE IMMEDIATELY AVAILABLE FOR USE. SUCH SUPPLIES AND MATERIALS
<br />SHALL INCLUDE, BUT NOT BE LIMITED TO, STRAW BALES OR OTHER MULCHING MATERIAL,
<br />SILT FENCING AND STAKES, FILTER FABRIC, ETC.
<br />6. DURING AND AFTER RUNOFF PRODUCING STORM EVENTS, THE CONTRACTOR SHALL
<br />MONITOR ALL EROSION CONTROL MEASURES AND SHALL PRIORITIZE IMPLEMENTATION AND
<br />MAINTENANCE OF EROSION AND SILTATION CONTROL MEASURES ABOVE ALL OTHERS.
