<br />THAT HAVE NOT UNDERGONE FINAL STABILIZATION. FINAL STABILIIZATION CAN BE ACHIEVED IN ONE
<br />OF THE FOLLOWING WAYS:
<br />ALL SOIL DISTURBING ACTIVITIES AT THE SITE HAVE BEEN COMPLETED <t4D ALL SOILS MUST BE
<br />STABILIZED BY A UNIFORM PERENNIAL VEGETATIVE COVER WITH A DENS; 1`Y OF 70 PERCENT OVER
<br />THE ENTIRE PERVIOUS SURFACE AREA, OR OTHER EQUIVALENT MEAN: NECESSARY TO PREVENT
<br />SOIL FAILURE UNDER EROSIVE CONDITIONS AND:
<br />A. ALL DRAINAGE DITCHES, CONSTRUCTED TO DRAIN WATER FROM T HE SITE AFTER CONSTRUCTIO
<br />IS COMPLETE, MUST BE STABILIZED TO PRECLUDE EROSION;

<br />WITH PERIMETER SEDIMENT CONTROLS.
<br />27, PIPE OUTLETS MUST HAVE ENERGY DISSIPATION INSTALLED WITHIN 24 HOURS OF CONNECTION
<br />TO WATERS OF THE STATE.
<br />SEDIMENT CONTROL PRACTICES:
<br />1. SEDIMENT CONTROL PRACTICES MUST MINIMIZE SEDIMENT FROM ENTERING SURFACE WATERS,
<br />INCLUDING CURB AND GUTTER SYSTEMS AND STORM INLETS.
<br />2. SEDIMENT CONTROL PRACTICES MUST BE ESTABLISHED ON ALL DOWN GRADIENT PERIMETERS
<br />BEFORE ANY UPGRADIENT LAND DISTURBING ACTIVITIES BEGIN. THESE PRACTICES SHALL REMAIN
<br />IN PLACE UNTIL FINAL STABILIZATION HAS BEEN ESTABLISHED.
<br />3. THE TIMING OF THE INSTALLATION OF SEDIMENT CONTROL PRACTICES MAY BE ADJUSTED TO
<br />ACCOMMODATE SHORT-TERM ACTIVITIES SUCH AS CLEARING OR GRUBBING, OR PASSAGE OF
<br />VEHICLES. ANY SHORT-TERM ACTIVITY MUST BE COMPLETED AS QUICKLY AS POSSIBLE AND THE
<br />SEDIMENT CONTROL PRACTICES MUST BE INSTALLED IMMEDIATELY AFTER THE ACTIVITY IS
<br />N COMPLETED HOWEVER, SEDIMENT CONTROL PRACTICES MUST BE INSTALLED BEFORE THE NEXT
<br />PRECIPITATION EVENT EVEN IF THE ACTIVITY IS NOT COMPLETE.
<br />4. ALL STORM DRAIN INLETS MUST BE PROTECTED BY APPROPRIATE BMPS DURING CONSTRUCTION
<br />UNTIL ALL SOURCES WITH POTENTIAL FOR DISCHARGING INTO THE INLET HAVE BEEN ESTABLISHED.
<br />5. TEMPORARY SOIL STOCKPILES MUST HAVE SILT FENCES OR OTHER EFFECTIVE SEDIMENT CONTROLS,
<br />AND CANNOT BE PLACED IN SURFACE WATERS, INCLUDING STORM WATER CONVEYANCES SUCH AS
<br />CURB AND GUTTER SYSTEMS, OR CONDUITS AND DITCHES.
