an important<br />
community project<br />
and one of the most<br />
challenging — and<br />
‘‘It’s<br />
rewarding — I’ve<br />
’’<br />
ever worked on<br />
by Laura Dillman Ripley<br />
Kevin MacDonald is a Cape Bretoner through and<br />
through. Born and raised in new Waterford, he<br />
returned to the Island following his university studies<br />
to enjoy a successful career as an engineer. Three years ago he was<br />
offered the chance to lead one of the most prominent remediation<br />
and environmental clean up projects in Canada in his own<br />
backyard, and he jumped at the chance.<br />
MacDonald is now CEO of the Sydney Tar Ponds Agency (STPA),<br />
charged with cleaning up the Tar Ponds and Coke Ovens sites.<br />
Situated in the heart of Sydney, nS, the sites contain one million<br />
tonnes of contaminated soil and sediment from nearly 100 years of<br />
steel and coke production.<br />
“It’s an important community project and one of the most<br />
challenging — and rewarding — I’ve ever worked on,” says<br />
MacDonald. “In 2008 I was working for the Cape Breton<br />
Regional Municipality (CBRM) as the director of engineering<br />
and public works. The STPA had already been established for a<br />
number of years at this time, working on the consulting, design,<br />
and technology phases of this huge project. When I heard they<br />
were looking for someone to help lead the construction phase of<br />
the site, I thought it would be a great opportunity.”<br />
And this great opportunity rang true. The construction and final<br />
stage of the Sydney Tar Ponds project is now more than halfway<br />
complete with a scheduled finish date of March 2014, a deadline<br />
MacDonald is confident his team will meet.<br />

“I work with a wonderful team. There are about 30 people at the<br />
Agency and their dedication to this project is phenomenal. We<br />
also work with various levels of government and consultants,<br />
contractors, and construction firms. The Tar Ponds clean up<br />
has been a real community effort with local firms, including a<br />
high level of Aboriginal participation, working on the project in<br />
various capacities.”<br />
The South Pond, which accounts for 50 per cent of the Tar Ponds<br />
site, is now complete and will soon have public access. Using a technology<br />
proven in other parts of the world, but never used in Canada,<br />
a pumping station was built on site and dewatered the tar pond<br />
sludge. The sludge was then mixed with cement in the South Pond.<br />
The mixture is covered with clay and other materials, which seal the<br />
cement mixture. Because of this process the once toxic sludge is now<br />
safely entombed, where ground water and rainfall can’t reach it or<br />
become contaminated. The South Pond site will become a green<br />
community space for all residents of the CBRM.<br />
“It’s amazing to see this kind of technology used right in my home<br />
province. This technology came to Cape Breton when a local firm<br />
was able to partner with a company in the US who were experts in<br />
this solidification/stabilization process. As a result, we now have<br />
our own experts in this process, the only ones in Canada.”<br />
Outside the STPA MacDonald keeps busy, with his heart always<br />
in Cape Breton. His family is still based in new Waterford and<br />
he enjoys summers at his cottage on the Mira River.
