Working on the night moves

Thursday 9 May 2019

The dramatic night lift of a barge, excavator and other machinery over Keepa Road Bridge in Whakatāne marked a smooth transition into the final section of the Kopeopeo Canal for the remediation project.

The Bay of Plenty Regional Council, with co-funding from the Ministry for the Environment, is working with the community to clean up dioxin-contaminated sediment in the Kopeopeo Canal. The canal was contaminated between the 1950s and late 1980s as a result of stormwater discharges from a former sawmill, which treated timber using Pentachlorophenol (PCP).

The Kopeopeo Canal Remediation Project is removing sediment from the canal using a barge-mounted cutter-suction dredge. Sediment is transferred along a pipeline to Geotubes® inside containment sites.

As the barge moves along the canal it needs to be lifted over bridges and pipelines enroute. This lift is the sixth and final of the bridge lifts along the project length.

Deputy Project Manager, Ken Tarboton, said that the process went very smoothly and according to plan.

“All of the other lifts have been in daylight hours, but this was at night because the contractor wanted to minimise any potential traffic-related effects.

“There was a lot of planning and preparation to ensure safety of all the workers on site and to make sure that there were contingencies and back-up plans in place. There is a lot of equipment to move in the right order – first removing all the materials from the barge and setting them aside so we can move the barge itself to the other side of the bridge. Then we needed to put it all back together again on the other side. Full credit to the contractor crane crew and site manager, Des McCleary from EnviroWaste Services Limited for such a smooth lift,” Mr Tarboton said.

Dredging will continue along the final section of the canal towards the confluence with the Orini Stream. Four kilometres of the total 5.1km has been dredged to date, marking approximately 80% completion.

Dredging is expected to be completed by the middle of the year, but works will continue on the Keepa Road containment site to cover and start bioremediation of the contained material. During that time, access through the site along the stopbank will remain restricted.

• The Bay of Plenty Regional Council (Rivers and Drainage Group) is working with the community to clean up dioxin-contaminated sediment in the Kopeopeo Canal. The canal was contaminated between the 1950s and late 1980s as a result of stormwater discharges from a former sawmill, which treated timber using Pentachlorophenol (PCP). While unknown at the time, PCP imported into New Zealand for use in the timber processing industry also included a percentage of impurities that contained dioxins.
• The project will take a staged approach to remove, safely store and treat up to 40,000m3 of sediment.
• The Project is jointly funded by the Regional Council and Ministry for the Environment’s Contaminated Sites Remediation Fund

Ellen Rykers on The Dig: Community Conservation – The Solution To The Biodiversity Crisis?

There are backyard trapping networks doing their bit for Predator Free 2050, farmers planting native trees along their waterways, and iwi protecting whenua rāhui. There are 62 biodiversity sanctuaries across 56,000 hectares, with around two-thirds of them community-led. There are citizen scientists counting birds in their backyards and landowners conserving habitat in 3,500 Queen Elizabeth II National Trust covenants.

It’s increasingly clear that a government agency alone cannot combat the biodiversity crisis successfully. These grass-roots initiatives are a growing resource in the conservation toolbox. More>>
