A proposal to clear vegetation within a PDWSA requires approval from DoW.)
Yes No If yes, please describe what category of area.
DoW were consulted during October 2011, seeking their advice regarding the proposed Yule River
Sand Project. DoW provided advice on the 7 th November 2011. The table (below) provides a summary
of DoW issues and how they have been addressed in the Mining Proposal (support information for this
referral).
DoW comments on Draft Mining Proposal for development and operation of the Yule River
Sand Project M47/1438 (This appears as Appendix 8 of the Mining Proposal)
To address for protection of the Yule
River Water Reserve
Assessment of/comment on information in report
1. Dry methods of sand extraction are to
be used. No extraction activities shall
take place below the water table.
2. A minimum of three metres of
undisturbed profile between the likely
future maximum water table and the
proposed final surface level is to be
maintained. The Department may allow
this to be reduced to two metres if the
proponent can demonstrate there is no
risk to the water source and approval of
the Department is obtained.
3. The proponent will be required to
confirm local groundwater levels prior to
the commencement of sand extraction.
4. Best practice, appropriate surface
water runoff management is used.
5. Servicing of mechanical components
of machinery particularly involving
liquids such as - coolants, hydraulic oils,
lubricants and brake fluids shall not be
undertaken on site. (Refer to WQPN 28
– Mechanical servicing and workshops;
and WQPN 56 – Tanks for elevated
chemical storage).
6. A satisfactory fuel management plan
is in place addressing:
a. Fuel spill prevention at fuel storage
areas;
b. Details of fuel transport and
refuelling;
c. A contingency plan for dealing with
fuel spillages;
d. Contamination incidents should be
reported immediately to the Water
Corporation and the Department of
Environment and Conservation (Refer to
WQPN 56 – Tanks for elevated
chemical storage).
7. An application needs to be made to
the Town of Port Hedland for the
domestic wastewater treatment system
proposed for use with a toilet at the site
14
Section 3.2 confirms that dry methods for extraction to be
used; and as per comment on 2. Immediately below – no
extraction below the water table in confirmed.
The commitments in section 4.4 “Groundwater levels will
be monitored from the groundwater monitoring bore.
Excavation of sand will not occur below a zone 3 metres
above the groundwater level and not below the clay river
bed” are acknowledged.
This may be done by appropriate location of the
groundwater monitoring bore that has been committed to
(Section 4.4) and/or other data considered reliable by the
Department of Water. Please refer to DoW‟s Operational
Policy No. 5.12 – Hydrogeological reporting associated
with a groundwater well licence, for further information.
1.3 Project objectives Table 4-4 and Section 4.3 satisfy
this requirement.
The Commitments Table and Section 4.8 Hydrocarbon
management generally cover this. A specific statement
needs to be made on it.
Section 4.8 Hydrocarbon management satisfies this
requirement.
Table 3-1 and Section 4.7 refer to a “toilet septic system
and transpirational leach field”. Accordingly, an
application needs to be made to the Town of Port
Hedland for this.
