EP-SECP-02: Site entry and exit points
1. Objectives/Targets        To avoid sediment being transported off the site by vehicles
2. Management Strategy       1) Dislodge loosely bound sediment attached to vehicles by vibration;
                             2) Trap dislodged sediment in the interstices of a metal grid or gravel bed; and
                             3) High pressure water hose to remove mud stuck to truck tyres during wet weather.
3. Tasks/Actions             1) Install an access path of crushed rock leading into the site, and directly to the
                             stockpile area. Rock pads should be at least 15 m long and 200 mm thick, with an
                             underlying layer of geo-fabric. Use cattle ramps as part of the structure to allow 2
                             complete rotations of the largest tyre leaving the site.
                             2) Install a high pressure water hose that can reach the rock pad, to remove
                             cohesive mud.
4. Performance Indicators    Spillage of sediment from the site through the exit, and onto the public road.
5. Monitoring                Inspection of the road surface beside the exit for sediment movement off the site.
6. Frequency/Deadlines       Inspect the exit: daily.
7. Responsibilities          Building contractor.
8. Reporting and Review      Exception reporting to the site manager and senior management.
9. Contingency               When sediment transport from the site access point is occurring:


                             1) Place sandbags at stormwater drain entry to prevent spilt sediment from being
                             washed into stormwater drains;
                             2) Report situation to site manager immediately, and request support;
                             3) Halt traffic until situation is under control;
                             4) Initiate corrective actions;
                             5) Remove sandbags when the spill has been cleared.
10. Corrective actions       1) Remove sediment from road surface using a spade an broom. Do not use a hose;
                             2) Building contractor to advise staff about responsibilities inherent with hosing off
                             mud;
                             3) Install extra length of pock pad or grid if necessary;
                            4) Improve delivery of high pressure water hose if possible;
                             5) Avoid work under muddy conditions.
