EP-SECP-03: Designated on-site stockpiles and waste receptacles
1. Objectives/Targets       To keep building materials and building waste on-site
2. Management Strategy      Containment of stockpiles and building waste wholly on the building site.
3. Tasks/Actions            1) Install skips or reo-cages in which to place waste, at multiple sites of convenience
                            across the site, so that winds cannot blow the waste off-site;
                            2) Have a designated site for stockpiling excavated earth, building sand, building
                            materials. Ensure that the stockpiles have designated covers with pegs to protect
                            them from wet weather, and are sufficiently distant from kerbside drains;
                            3) The designated area for cement and paint materials must be away from kerbside
                            drains;
                           4) Install a geo-log upslope to divert flow around the stockpile;
                            5) Install a sediment fence down-slope of stockpile area to collect sediment; and
                           6) At the end of each day, or before the onset of rain, cover and securely peg
                           stockpiles. Ensure that waste has been placed in the waste receptacle-
                            1) Sediment accumulation against the sediment fence;
                           2) Stockpile covered when required: and
                           3) Effective containment of waste.
                           1) Inspection of geo-log and sediment fence for structural integrity;
                           2) Inspect the sediment fence for sediment accumulation,
                           3) Inspection of stockpile for effective cover, or wetness and erosion if cover has
                           been removed; and
                           4) Inspection of the waste receptacle and building site for litter containment.
6. Frequency/Deadlines     Daily inspection.
7. Responsibilities        Building contractor.
8. Reporting and Review    Exception reporting to the site manager and senior management.
9. Contingency             When loss of materials from the stockpiles and waste receptacles is occurring:
                           Waste Receptacle
                           1) Report situation to site manager immediately, and request support;
                           2) Collect loose litter and place in bags.
                           3) Identify point of failure in waste receptacle and temporarily bridge the point of
                           failure;
                           4) Place bagged litter in waste receptacle,
                           5) Initiate corrective actions.


                           Stockpile
                            1) Report situation to site manager immediately, and request support;
                           2) Identify points of failure in upstream flow control or downstream sediment fence.
                           Place sandbags upslope to divert flow away from the points of failure;
                           3) Initiate corrective actions;
                           4) Collect water quality samples at inflow and outflow points (section 11)
                           1) Repair geo-logs, perimeter stockpile covers, waste receptacles, and sediment
                           fences if required;
                           2) Address upslope controls if required (refer to EP-SECP-01);
                            3) Building contractor to reinforce the need to keep a tidy site and cover stockpiles.
