Update on Randle Reef Sediment Remediation Project

February 13, 2015 - Hamilton, Ontario - The Randle Reef project
partners are pleased to inform the community that a path forward
has been established for the project.

In the summer of 2014, extensive consultation occurred with
industry experts to determine options to advance the project
within the current budget envelope. After careful consideration
of all information received from industry, the project partners
have identified modifications to the current project design that
should result in significant cost savings without compromising
the environmental goals of the project. For example:

• Additional sampling of the harbour bottom in and around the

Engineered Containment Facility (ECF) footprint was completed in
the summer and fall of 2014 and allowed dredging areas and
volumes of contaminated sediments to be more precisely defined.
These activities also confirmed the viability of the proposed
modifications to the ECF;

• The modified ECF will continue to contain Priority 1 and

Priority 2 sediments, which are the most highly contaminated
sediments at the site. A larger portion of the lesser
contaminated sediments will now be capped in place using in situ
capping. This will enable a reduction in dredging volumes and
associated costs, as well as a reduction in the size of the ECF
of approximately 15 per cent;

• The overall length of the ECF has been shortened and the

updated design has fewer right angles, which will make dredging
and rock placement activities between the containment facility's
inner and outer walls easier and faster;

• Construction processes were also simplified to yield cost

reductions associated with items such as material handling and
installation of the steel walls.

With these modifications, the project's environmental objective
will continue to be achieved. The Randle Reef project is a key
initiative in restoring Hamilton Harbour and removing it from
the list of Great Lakes Areas of Concern. The project partners
remain committed to working together on this clean-up project
and starting construction as quickly as possible.

Stage 1 of the project is expected to be re-tendered in early
2015. Work is expected to commence this year in Hamilton
Harbour with the reconstruction of a dock wall adjacent to the
ECF, to permit contaminated sediments to be removed from this
area.

The Governments of Canada and Ontario, the City of Hamilton, the
Hamilton Port Authority, U.S. Steel Canada, the City of
Burlington, and Halton Region would like to thank everyone who
participated in Industry Day in July, and in the follow-up
one-on-one sessions held throughout the summer. The constructive
feedback that we received was very helpful in determining a
solution to quickly move the Randle Reef project forward.
