                                  SCHEDULE D - STORMWATER MANAGEMENT


  Contaminant Releases Caused by Rainfall

 (D1)       The environmentally relevant activity must be carried out by such practicable means necessary to
            prevent the contact of incident rainfall and stormwater runoff with wastes or other contaminants.

 Acid Sulphate Soils

 (D2)       Any acid sulphate soils or potential acid sulphate soils disturbed, extracted or unearthed as a result
            of carrying out the environmentally relevant activity must be stored and/or treated and/or disposed of
            so as not to cause environmental harm to surface waters and/or groundwaters.

 Maintenance and Cleanup

 (D3)       The maintenance and cleaning of vehicles and any other equipment or plant must be carried out in
            areas from where contaminants cannot be released into any waters, roadside gutter or stormwater
            drainage system.

 (D4)       Any spillage of wastes, contaminants or other materials must be cleaned up as quickly as
            practicable. Such spillages must not be cleaned up by hosing, sweeping or otherwise releasing such
            wastes, contaminants or material to any stormwater drainage system, roadside gutter or waters.

 Bunding

 (D5)       All chemical tank storages must be bunded so that the capacity of the bund is sufficient to contain at
            least 100% of the largest storage tank plus 10% of the second largest tank within the bund.

 (D6)       All chemical drum storages must be bunded so that the capacity of the bund is sufficient to contain at
            least 25% of the maximum design storage volume within the bund.

 (D7)       All bunding must be constructed of materials which are impervious to the materials stored.

 (D8)       The base and walls of all bunded areas must be maintained free from gaps or cracks.

 (D9)       All bunding must be roofed where practicable.

 (D10)      Where it is impractical to completely roof a bunded area the registered operator must ensure that any
            stormwater captured within the bund is free from contaminants or wastes prior to any release.

 (D11)      All empty drums must be stored with their closures in place.

 Minimise Infiltration to Sewers

 (D12)     The registered operator must take all reasonable and practicable measures to minimise infiltration
           into sewers.

 (D13)     For the purposes of demonstrating compliance with condition D12, the registered operator must
           periodically report to the administering authority on the following matters:

           (i)        the estimated level of infiltration;
           (ii)       the reasonable and practicable measures intended to minimise infiltration;
           (iii)      the actions taken to minimise infiltration; and
