       3.      THE CONTRACTOR IS TO CONSTRUCT AN ENTRY/EXIT SEDIMENT TRAP AS DETAILED PRIOR
               TO THE COMMENCEMENT OF ANY EARTHWORKS.

       4.     ALL STOCKPILES TO BE TEMPORARILY GRASSED & GRADED TO ENSURE CONTROL OF
              RUNOFF. ALTERNATIVELY, SEDIMENT FENCES TO THE DOWNSTREAM FACE OF STOCKPILES
              ARE TO BE INSTALLED, WITH CUT-OFF DRAINS UPSTREAM.

       5.     ROUGHEN ALL SURFACES PRIOR TO TOPSOIL PLACEMENT. ROUGHENING TO CONSIST OF
              LATERAL (90° TO SLOPE) GROOVES 100mm DEEP AT 2m MAX. SPACINGS.

       6.     ALL EXPOSED SURFACES, ONCE COMPLETED SHALL BE IMMEDIATELY STABILISED TO
              PREVENT EROSION. ROUGHEN SURFACE BY FORMING LATERAL GROOVES 50mm DEEP AT 1m
              MAX. SPACINGS AND 5m MAX. LENGTHS.

       7.     SEDIMENT & EROSION CONTROL DEVICES (OTHER THAN THOSE ALREADY SHOWN) TO BE
              INSTALLED WHERE NECESSARY & AS DIRECTED ON SITE BY THE SUPERINTENDENT.

       8.     SEDIMENT & EROSION CONTROL DEVICES ON THIS PLAN ARE INDICATIVE ONLY. IT IS THE
              RESPONSIBILITY OF THE SITE MANAGER TO ENSURE THAT THE INTENT OF THIS PLAN AND
              THE ENVIRONMENTAL MANAGEMENT PLAN ARE COMPLIED WITH.

       9.     EROSION AND SEDIMENT CONTROL DEVICES/STRATEGIES TO BE COMPLETED PRIOR TO
              DISTURBANCE OF THE SITE, AND SHALL REMAIN IN PLACE UNTIL PERMANENT WORKS ARE
              COMPLETE AND CATCHMENT VEGETATION IS ESTABLISHED (75% GRASS COVER MINIMUM) .

       10. AREAS OF WORKS THAT REQUIRE DISTURBANCE OF SOIL SHALL BE KEPT TO A MINIMUM TO
           LIMIT THE EXPOSURE OF SOIL TO RAIN-DROP IMPACT AND OTHER FORMS OF
           WIND/STORMWATER EROSION.

       11. ALL WORK IS TO BE COMPLETED IN ACCORDANCE WITH ALTA PROJECTS STANDARD
           SPECIFICATION.
