• Communications – Abby Tozer

• Recent sediment sampling results – Brendon Love

• Update on variation application – Brendon Love

• Independent Monitor feed back – Andrew Kohlrusch

• Update on tender process – Brendon Love

• Other matters – Brendon Love

• Wood waste site progress - Ken Tarboton

Recent sediment sampling results

• Sediment sampling and analysis was carried out in the canal and adjoining drains / wetlands (link to sampling locations)

• The purpose of the sampling was:

– To baseline the canal prior to handing the project site to the contractors

– To ensure that contaminant levels within side drains and areas not previously investigated were below remediation targets

Sample Locations - West• Samples circled in red

are above remediation target of 60 pg I-TEQ/g

• These are in privately owned part of canal outside of project scope and MfE deed funded area

Sample Locations - EastSamples circled in red are above remediation target of 60 pg I-TEQ/g

Bulk of dioxin (86%) above remediation threshold will be removed by current project

Actions proposed

• Some locations are outside of the scope of the consents and project funding deed

• Further sampling has been completed to define the extent of elevated contaminants –analysis underway

• Once defined, remediation or management options can be considered.

• Additional funds & approval of new consents will be required

• Land is not owned by BoPRC

7

• Containment of contaminant upstream of SH30 is required to ensure current project objectives are not compromised (e.g. re-contamination)

Actions proposed (cont.)

8

• Floodgates now in normal operation

• Discussions with landowners underway

• Project team considering alternative delivery approaches (e.g. east to west)

Update on variation application

• Consent variation application lodged on 18 April 2016

• s92 request received and responded to

• Focus has been on water quality in discharge and further consideration of flood mitigation control measures

• Final report to Independent Commissioner in late July

• Decision expected in August

9

RFP process

• Two very strong tenders evaluated based on non-price attributes

• Prices received outside of budget

• Negotiation underway with preferred contractor

• Focus to develop revised implementation plan that meets FY16/17 budget and long term project goals

10

• Competitive Dialogue undertaken Feb.-April.

• Stage 2 RfP closed on 27 May

• RFP responses evaluated

Other matters

• Fence installed between the canal and Keepa Road walkway/cycleway

• Filtrate results still close to detection limit (5 pg I-TEQ/L)

• Baseline Air Quality report online

• Bioremediation cell testing ongoing

• Some vegetation clearance and mulching completed along canal

Wood waste site progress

• Contaminated site working group (CSWG) meetings (Feb, April, July 2016)

• Revised draft management plans being written

• Sites prioritised for site inspections based on desktop assessment of risk

• Site inspections underway to assess risks, wood waste cover and reinforce management plan requirements by owners / lessees

• New signage proposed for CSWG approval – 26 July
