       is required to sign off on any new bund development to ensure that the correct permeability is
       achieved.
    2. The compound is required to be large enough to contain the larger of the below criteria:
            a. 110% of the largest vessel / interconnected system; and
            b. 25% of the total volume stored in the compound.
    3. The location of the bund to the closest tank shall be in accordance to AS 1940 – 2004 section
       5.8.3.
    4. Bulk storage vessels (Tanks and pods) will be positioned ½ the height of the vessel away from
       the edge of the bund.
            a. Hight of the vessel excludes the height of the bund wall.
    5. The area should be kept clear of all extraneous material.
    6. Packages shall not be placed where they could jeopardize entry or exit.
    7. Vegetation that could become a fire hazard should be removed.
    8. Any compound drain valve shall be kept closed and locked except during supervised draining.
       A notice in words “BUND DRAIN VALVE – TO BE KEPT CLOSED AND LOCKED” shall be
       displayed.
    9. Spills should be cleaned up as soon as possible inside or outside the compound.
    10. The facility will include a sump to allow the recovery of liquids.

        possible labels facing out for easy identification.
    13. Only Hydrocarbons or Chemicals to be stored in the designated bund storage area.



3.3. Hydrocarbon Pipe Works

 3.3.1    Underground Hydrocarbon Pipework
Underground pipes containing hydrocarbons will be leak tested every 12 months.

Underground pipe work will be leak tested in accordance to the specifications detailed in AS/NZS
2885.5.2002 Pipeline – Gas & Liquid Petroleum field pressure testing.

Records of the leak testing will be distributed to:
            o Engineering Department.
            o Environmental Department.
            o Mine/ Facility Managers.


 3.3.2    Surface Hydrocarbon Pipework
Surface pipe work containing hydrocarbons must be contained within a bunded structure. The pipe
work will be visually inspected for leaks during the same annual inspection as the underground pipe
works conducted by the Engineering Department.

The surface pipe work will also be visually inspected for leaks during the Environmental Area Audit
according to the Area Environmental Audit Schedule (SIG-ENV-SC001).


3.4. Treatment of Wastewater from Hydrocarbon Facilities

All site workshops which are utilised for mobile and static equipment servicing must be equipped with
suitable drainage and treatment facilities for the effective containment and treatment of oily water
effluent. These facilities can include triple interceptor pits, hydrocyclones or coalescing plate
separators. The engineering department will be approached to advise with the choice of oil water
separator to be installed.
The treatment of wastewater must achieve a reading of between 15 - 30ppm Total Petroleum
Hydrocarbons (TPH). Discharge of the treated wastewater must be into a controlled environment,
being a lined pond or dedicated evaporation/ soakage pit, according to Department of Water, Water
Quality Protection Note WQPN 68.

All hydrocarbon / effluent treatment facilities are to be serviced according to manufacturer’s
instructions and standards, with reference to SIG-ENG-ELEC-WI001, and workshop staff members
are required to keep records of servicing and maintenance conducted.
The design and sourcing of these facilities should consider, at a minimum, volume of water generated
from the workshop, frequency of use, sediment load and recycling of wash down water.


Operations and responsibilities include the following:
          1. The day to day maintenance of the oil water separators is the responsibility of the
             workshop (Contractor) staff;
          2. The delivery of a fit-for-purpose separator to the workshop is the responsibility of SIGM;
          3. SIGM will monitor the quality of the discharge and provide feed back to the workshops for
             management quarterly. Monitoring of these facilities will be undertaken by the
             environmental department.
          4. Hydrocarbon discharge levels can be managed by:
                    a. Increasing/ decreasing the frequency of cleaning; and/or
                    b. Changing the brand or type of degreaser being used.
          5. Shared facilities will be managed by the contractor who houses and maintains the wash
             pad facility. Clear instructions on the use of the wash pad including the types of degreaser
             to be used will be communicated between contractors.


3.5. Spill Response Kits

Spill response kits must be stored at each hydrocarbon storage area and maintenance workshop. The
content of the spill kits will vary depending on the situation and machinery involved.
The maintenance and upkeep of the spill kits is the responsibility of the contactor/ workshop. Extra
supplies for the spill kit should be readily available from the workshops storeroom.
Spill response kits should contain, but not necessarily be limited to, the following.
                                                                                          Bio Active

3.6. Degreasers.
Quick break degreaser’s shall be used on site. Appendix 1 provides a list of products that meet the
quick break criteria. To be allowed on site the quick break degreaser must meet the Hazardous
Material Critical Hazard Standard (SIG-EHS-CHS002.)

Alternative products may be procured, however they will need to meet the above standard and be
endorsed by the Environmental department. Documentation to support the quick break properties
must be provided.

Quick Break criteria is listed in Appendix 2.


4. PROCEDURAL REQUIREMENTS

4.1. Supply of Hydrocarbons
Areas will provide the Environment Department with monthly oil accountability data as required by the
Environment Department, and in line with their KPI’s, in order to facilitate oil accountability tracking on
site.


4.2. Hydrocarbon Awareness Training
All contractors and operators on site will have attended a SIGM hydrocarbon awareness session held
by the environmental department. The Hydrocarbon awareness is valid for 24 months. It is the
responsibility of the Contractors to manage the attendance of their staff at one of the SIGM training
sessions for hydrocarbon awareness.


4.3. Awareness and Use of Hydrocarbons

The responsible use and handling of hydrocarbon based products should minimise potential for waste
through spillage. All contractors and suppliers must be aware of, and follow, the safe handling and
transfer of hydrocarbon based products outlined in this Standard.
Contractors must be able to demonstrate that they conform to the appropriate written procedures to
undertake work and practices for individual tasks.
Accountabilities for loading, unloading and transporting of hydrocarbons and waste oils should be
clearly assigned for both internal and external suppliers and transporters. Where accountability has
not been clearly assigned, it falls with the contractor operating on site.


4.4. Disposal of used Hydrocarbons and Containers

Used hydrocarbons and hydrocarbon containers must be disposed of responsibly and in accordance
with contractual requirements. No hydrocarbons are permitted to be sent to landfill or a general waste
facility. Each working area will maintain a clearly marked system of waste separation on all bins
(Colour code/ Signage etc). The following details apply to hydrocarbon waste streams:
Oil - Waste oil will be stored in suitably labelled containers and be collected and sent off site by a
licensed waste management provider.
Grease – Waste grease will be stored in suitably labelled containers and be collected and sent off site
by a licensed waste management provider.

Oily Waste Water – Oily waste water should be collected and sent off site by a licensed waste service
provider. Contaminated water from vehicle washing facilities can be disposed of at a bioremediation
facility on site, in accordance with procedure SIG-ENV-PR039.
Oil Filters - Oil filters are to be collected in dedicated containers and be collected and sent off site by
a licensed waste management provider.
Oily Rags – Oily rags must be stored in suitably labelled containers and be collected and sent off site
by a licensed waste management provider.
Areas will keep a copy of the receipts of all hydrocarbons sent off site for disposal, and will provide
copies of waste tracking notes to the Environment Department on a monthly basis. In addition, waste
tracking notes are to be kept in the respective area for a minimum period of 2 years and made
available for audit on request.


4.5. Contaminated Sites

All soils around workshops and other contaminated areas should be assessed regularly and if
contaminated remediation should be considered as soon as possible, using a bioremediation facility
(see SIG-ENV-PR039) or in-situ bioremediation as applicable. The Environmental Department will
maintain a register of contaminated sites (SIG-ENV-RV002).


4.6. Spill Response

Spills of hydrocarbon materials are to be managed according to the Hydrocarbon Spills Procedure
(SIG-ENV-PR003). All hydrocarbon spills, regardless of whether they occur on site or in transit to or
from the operations and regardless of size and volume, must be cleaned up by site personnel in the
affected area (with direction from the site’s environmental representatives) and reported to the
Environment Department. Spills of greater than 250L must be reported to the Environment
Department within 24 hours.
All soils contaminated with hydrocarbons must be excavated, handled and bioremediated according to
SIG-ENV-PR039-Bioremediation Pad Procedure.
A spillage register or incident tracking system shall be developed, maintained and made available at
all times to internal or external auditors.
