CLC quarterly meeting
- GTP started up 5 December
• Recent investigations into the possibility of pumping more groundwater to maximise hydraulic containment:
- Identified that extraction beyond ~7 ML/day increases risk of
subsidence, particularly on the BIP
• Continue industrial reuse of treated groundwater
• Will look for opportunities to treat other water sources for industrial
reuse, but no feasible projects have been identified
• Plan to improve the efficiency of the biological treatment of water
Orica Botany Groundwater Cleanup
• Cumulative 6.1 billion litres of groundwater treated and 730 tonnes
of contaminants destroyed (as of Sep ’09)

Orica Botany Groundwater Cleanup
• As expected, results consistent with previous monitoring rounds
• Large decrease in the estimated average CHC concentration for entire PCA aquifer between Jul 2002 and Sep 2009
• Contaminant concentrations less than ANZECC Trigger Values for
all pore water discharge interface samples in Penrhyn Estuary
• Surface water concentrations in Springvale Drain and Estuary hundreds of times lower than 5 years ago
• Conclusions of Consolidated Human Health Risk Assessment
(2005/2006) do not change
• Trial extension proposed to test anti-fouling agent and injection well
maintenance techniques to extend life of wells in case of long term
shutdown
– Maintenance & optimisation of hydraulic containment
– Chemical & hydraulic monitoring programs for:
- Groundwater & surface water
– Source area management
– Follow-up on 2004-2005 bioremediation field trials
– North-east corner of Southlands Block 2
– Injection of bio culture developed by Centre for Marine
Bio-Innovation (at UNSW)
– To see whether it can achieve greater bioremediation that with
nutrients alone
– Targeting EDC
2008-2009 EPL2148 Annual Return – BGC Project Conditions
• Seven minor non-compliances; all other discharges to air and water from the GTP met stipulated licence conditions
1. GTP weather station unavailable for 24 hrs due to lightning strike
2. Total Solid Particles exceedance at GTP stack
- 42.2 mg/m3 compared to limit of 20 mg/m3
- No harm to human health or the environment (Prof B Priestly IMC Task 24)
3. Loss of a treated water test sample by the testing laboratory
4. Minor exceedance of oxidised nitrogen in discharged treated water
- 0.11 mg/L compared to limit of 0.1 mg/L
- No environmental harm (URS risk assessment)
5. Treated water discharge temperature exceedances
- Shroud to reduce pipeline heating up in hot weather
6. Minor spill of groundwater from a pump at the BIP Containment Line
- Preventative measures in place

• Orica has submitted a draft VMP to DECCW for
review and DECCW is finalising comments.
• Content of VMP includes:

HHRA; and
4
Former Chlor Alkali Plant
• DECCW’s Contaminated Site Section has reviewed Orica’s scope of works to address mercury contamination and provided comments.
• We understand that Orica is in the process of
preparing a separate VMP for mercury. If approved by DECCW, the VMP will be the key regulatory instrument for the mercury clean up and management.
DECCW update on regulation 08/12/09
CLC quarterly meeting 3
• EPA currently processing a Notice which will vary EPL 2148:
- Align wording of EPL and CPWE project Approval;
- Amend timetable for CPWE works; and
- Add new PRP – implement options report related to discharge temperature.
• 2008/2009 Licence Annual Return submitted – 8 non- compliances.

for extension with a view to permitting full scale
works if trial results are satisfactory.
DECCW update on regulation 08/12/09
CLC quarterly meeting 4
• Change to the Deed of Cross Guarantee - DECCW

CLC Update
James Stening
– Render FCAP site suitable for industrial/commercial use
• Voluntary Management Proposal - aim to submit to DECCW this year
• Chris Jewell appointed as DECCW accredited Site Auditor
• URS engaged to prepare a Remediation Action Plan (RAP)
– Soil remediation plans, including treatment criteria
– Environmental controls, including mercury emission controls
– Environmental monitoring program
• Soil remediation currently scheduled for July 2010 for ~5 months
– Category 2 works – does not require an Environmental Assessment
• Orica will consult with the CLC, BIP employees, Denison Street
residents and railway operators as the project progresses
FCAP mercury investigations 08/12/09
Quarterly CLC Meeting
– To be established on Block L
– Limited plant availability
on site) – preliminary estimate
• Contaminated soil fractions - plan to
send to licensed landfill
• ~12,000 tonnes of contaminated
licensed landfill Source: highlandsremediation.com
Mitigation of mercury emissions
• Air emission modelling required to plan detailed design of remediation approach and emission control measures
• Mercury emission sources to be managed: - Fugitive emissions from soil washing plant - Excavated soil stockpile (at soil washing plant) - Contaminated soil fractions (at soil washing
plant) - Excavated surfaces
• Trials planned to determine approach to control emissions from excavated surfaces - Trials at areas excavated during concrete
cutting trials - Custom-made tarpaulins to be trialled to
capture vapour - Vapour might be directed to small stack with
activated carbon filters – licence change to be requested from DECCW
FCAP mercury investigations 08/12/09
Quarterly CLC Meeting
Further Groundwater Investigations
• Two new wells installed west of railway line • Additional offsite groundwater sampling to
further understand movement of mercury plume
• Geochemical analyses to better understand how groundwater conditions could be influencing the mobility of mercury
