Environmental Control
Vapour / landfill gas
> Sealed well heads during extraction;
> System connected to landfill gas system and GAC
vessels, 2 in series.
Spillage control
> Double walled LNAPL collection/storage tanks;
> Sealed work area around well head;
> Secondary contained transfer hosing;
Environmental Control
Noise
> Operations during business hours so no change to
current noise profile.
Monitoring:
> Portable Landfill Gas and Trace Gas monitors
> Samples of LNAPL, leachate & vapour obtained &
analysed by laboratories

Continuous monitoring of vapours in the work area.
Trigger thresholds based on unprotected worker exposure.
PPE includes face shields & respirators.
Response to trigger = monitor, locate & isolate source, shut down.
Workers protected = Community protected.
Independent Review Panel
> Purpose :
1. Verify field work was completed according to plan
2. Review the data
3. Assist with decision making during the trial
4. Review the LNAPL Trial report prepared by EHS Support
5. Provide a statement to the EPA on the trial report
LNAPL Trial Summary
> Field trials planning and equipment build is completed
and field works are commencing with first well test
planned mid March
> The results will be reported to the community in May
2014
> The project includes LNAPL destruction trials

Two conditions
-Groundwater sample locations must
be accessible
-Groundwater restricted use zone
Environmental Audit Questions
-Audit report to be uploaded to Transpacific’s community
website www.transpacific.com.au/tullamarine
- TPI has arranged for the Engineer (Kleinfelder) &
Auditor to present to the community:
12 March at Mantra Hotel, 7pm
2014 Technical Review (Commencing)
> Involves review of all surface water and groundwater
data collected since last review (mid 2011)
> Golder prepared the 2011 review & Auditor completed
his report July 2012
> Kleinfelder will be preparing the 2014 review
> Objective (i) to compare monitoring against management
plan requirements and (ii) to determine if the current
monitoring arrangements adequate Prepared by Golder, 2012
