<br />SEDIMENT CONTROL PRACTICES:
<br />CITY OF ORONO RESOLUTI
<br />PERMANENT COVER:
<br />1. SEDIMENT CONTROL PRACTICES MUST MINIMIZE SEDIMENT FROM ENTERING
<br />SURFACE WATERS, INCLUDING CURB AND GUTTER SYSTEMS AND STORM SEWER INLETS.
<br />2. SEDIMENT CONTROL PRACTICES MUST BE ESTABLISHED ON ALL DOWN GRADIENT
<br />PERMITERS BEFORE ANY UPGRADIENT LAND DISTURBING ACTIVITIES BEGIN. THESE
<br />PRACTICES SHALL REMAIN IN PLACE UNTIL PERMANENT COVER HAS BEEN
<br />ESTABLISHED.
<br />3. THE TIMING OF THE INSTALLATION OF SEDIMENT CONTROL PRACTICES MAY BE
<br />ADJUSTED TO ACCOMMODATE SHORT-TERM ACTIVITIES SUCH AS CLEARING OR
<br />GRUBBING, OR PASSAGE OF VEHICLES. ANY SHORT-TERM ACTIVITY MUST BE
<br />COMPLETED ASQUICKLY AS POSSIBLE AND THE SEDIMENT CONTROL PRACTICES MUST
<br />BE INSTALLED IMMEDIATELY AFTER THE ACTIVITY IS COMPLETED. HOWEVER, SEDIMENT
<br />CONTROL PRACTICES MUST BE INSTALLED BEFORE THE NEXT PRECIPITATION EVENT
<br />EVEN IF THE ACTIVITY IS NOT COMPLETE.
<br />4. ALL STORM DRAIN INLETS MUST BE PROTECTED BY APPROPRIATE BMPS DURING
<br />CONSTRUCTION UNTIL ALL SOURCES WITH POTENTIAL FOR DISCHARGING TO THE INLET
<br />HAVE BEEN STABILIZED,
<br />5. TEMPORARY SOIL STOCKPILES MUST HAVE SILT FENCES OR OTHER EFFECTIVE
<br />SEDIMENT CONTROLS, AND CANNOT BE PLACED IN SURFACE WATERS, INCLUDING
<br />STORM WATER CONVEYANCES SUCH AS CURB AND GUTTER SYSTEMS, OR CONDUITS
<br />AND DITCHES.
<br />6. SITE CONSTRUCTION ENTRANCES WILL BE AS SHOWN ON THE PLAN. ROCK
<br />CONSTRUCTION ENTRANCES SHALL BE INSTALLED AT EACH ENTRANCE.
<br />POLLUTION PREVENTION
<br />MANAGEMENT MEASURES:
<br />THE CONTRACTOR SHALL IMPLEMENT THE FOLLOWING POLLUTION PREVENTION
<br />MANAGEMENT MEASURES ON THE SITE:
<br />1. SOLID WASTE: COLLECTED SEDIMENT, ASPHALT AND CONCRETE MILLINGS,
<br />FLOATING DEBRIS, PAPER, PLASTIC, FABRIC, CONSTRUCTION AND DEMOLITIONDEBRIS
<br />AND OTHER WASTES MUST BE DISPOSED OF PROPERLY AND MUST COMPLY WITH
<br />MPCA DISPOSAL REQUIREMENTS.
<br />2. HAZARDOUS MATERIAL: OIL, GASOLINE, PAINT AND ANY HAZARDOUS SUBSTANCES
<br />MUST BE PROPERLY STORED, INCLUDING SECONDARY CONTAINMENT, TO PREVENT
<br />SPILLS, LEAKS OR OTHER DISCHARGE. STORAGE AND DISPOSAL OF HAZARDOUS
<br />WASTE MUST BE IN COMPLIANCE WITH MPCA REGULATIONS.
<br />3. CONCRETE WASHOUT IS DONE TRUCK BY TRUCK WITH A MOBILE WASHOUT
<br />SYSTEM PROVIDED AND COMPLETED BY THE CONCRETE CONTRACTOR. RUNOFF
<br />MUST BE CONTAINED AND WASTE PROPERLY DISPOSED OF.

<br />COMPLETE, OR ANOTHER OWNER/OPERATOR (PERMITTEE) HAS ASSUMED CONTROL OF ALL
<br />AREAS OF THE SITE THAT HAVE NOT UNDERGONE PERMANENT COVER. PERMANENT COVER
<br />CAN BE ACHIEVED IN THE FOLLOWING WAY:
<br />ALL SOIL DISTURBING ACTIVITIES AT THE SITE HAVE BEEN COMPLETED AND ALL SOILS MUST BE
<br />STABILIZED BY A UNIFORM PERENNIAL VEGETATIVE COVER WITH A DENSITY OF 70 PERCENT
<br />OVER THE ENTIRE PERVIOUS SURFACE AREA, OR OTHER EQUIVALENTMEANS NECESSARY TO
<br />PREVENT SOIL FAILURE UNDER EROSIVE CONDITIONS AND;
<br />A. ALL DRAINAGE DITCHES, CONSTRUCTED TO DRAIN WATER FROM
<br />THE SITE AFTER CONSTRUCTION IS COMPLETE, MUST BE STABILIZED TO
<br />PRECLUDE EROSION;
<br />B. ALL TEMPORARY SYNTHETIC, AND STRUCTURAL EROSION PREVENTION
<br />AND SEDIMENT CONTROL BMPS (SUCHAS SILT FENCE) MUST BE REMOVED AS
<br />PART OF THE SITE PERMANENT COVER; AND
<br />C. THE CONTRACTORS MUST CLEAN OUT ALL SEDIMENT FROM CONVEYANCES AND
<br />FROM TEMPORARY SEDIMENTATION BASINS THAT ARE TO BE USED AS
<br />PERMANENT WATER QUALITY MANAGEMENT BASINS. SEDIMENT MUST BE
<br />STABILIZED TO PREVENT IT FROM BEING WASHED BACK INTO THE BASIN,
<br />CONVEYANCES OR DRAINAGE WAYS DISCHARGING OFF-SITE OR TO SURFACE
<br />WATERS. THE CLEAN OUT OF PERMANENT BASINS MUST BE SUFFICIENT TO
<br />RETURN THE BASIN TO DESIGN CAPACITY.
<br />EROSION CONTROL SCHEDULE:
<br />1. PRIOR TO ANY CONSTRUCTION OR DEMOLITION, SILT FENCE AND FILTERS SHALL
<br />BE INSTALLED AS SHOWN TO INTERCEPT RUNOFF.
<br />2. ALL EROSION CONTROL INSTALLATIONS SHALL REMAIN IN PLACE AND BE MAINTAINED
<br />IN GOOD CONDITION BY THE CONTRACTOR UNTIL THE SITE HAS BEEN RE -VEGETATED.
<br />CONTRACTOR MAY REMOVE NECESSARY SILT FENCING/FILTERS TO CONSTRUCT ROADWAYS,
<br />WHILE MAINTAINING ADEQUATE EROSION CONTROL IN ADJACENT AREA.
<br />3. SUFFICIENT TOPSOIL SHALL BE STOCKPILED TO ALLOW FOR THE REPLACEMENT OF 4" OF
<br />TOPSOIL FOR DISTURBED AREAS TO BE RE -VEGETATED.
<br />4. THE CONTRACTOR SHALL SCHEDULE SITE GRADING, UTILITY INSTALLATION AND PAVEMENT
<br />CONSTRUCTION SO THAT THE GENERAL SITE CAN BE MULCHED AND RE -SEEDED SOON
<br />AFTER DISTURBANCE. AREAS THAT WILL NOT BE SUBJECT TO CONSTRUCTION TRAFFIC
<br />SHALL BE SEEDED (MnDOT MIX 22-112 ® 100#/AC AND MULCHED OR SODDED WITHIN
<br />SEVEN (7) DAYS OF BEING DISTURBED.
