“And then the meat-and-potatoes is the actual mitigation,”
said Lee. “Once you’ve identified impacts – even if they’re
perceived as relatively innocuous – you may need to look at
developing mitigation strategies.”
These might include “refuelling procedures, concrete
management and spill procedures or salvage requirements
to remove fish from the work area before construction commences.
And then there are usually some ancillary plans that
accompany the EMP,” he said. These take in such areas as
construction material and equipment management, waste
management, spill prevention, emergency response, erosion
and sediment control, noise and air quality.
“Something becoming more of a central issue in the overarching
EMP is the invasive species management plan;
occasionally, there’s also a species-at-risk management plan.
It would have to be monitored appropriately,” said Lee. “That
leads to the last condition of the EMP: the environmental monitoring
and reporting.”
If this sounds daunting, it can be outsourced to a specializing
firm.
“If there are environmental concerns, we’ll hire an environmental
consultant and do an EMP,” said Kaufmann. “There’s
always a concern that there may be something we don’t know,
so we will outsource our environmental management to a
Qualified Environmental Professional (QEP).”
Similarly, Flatiron contracted Spencer Environmental
Management Services Ltd. on the Northeast Anthony Henday
project to manage the EMP.

COVER STORY
“The money spent on an environmental company is well
worth it, as they’re the experts who know what the government
requires for compliance and audit protocols,” said Hodge. “As
regulations change and new species come on the protected list
– and this project is in the middle of a migratory bird flyway –
for a contractor to be knowledgeable of the many regulations
and licenses required would require a substantial amount of
time and research.”
Practical measures
Many companies practice voluntary environmental measures,
such as using biodegradable hydraulic oil or replacing parts
that could potentially cause a spill.
“We put our hydraulic hoses on a timed rotation,” said
Stirling Larwill, health, safety and environment manager
for Force Pile Driving. “They’re replaced every 8,000 hours,
whether they’re showing signs of wear or not.”
The company also uses Finnish-made Junttan machines.
“They are hydraulically driven, so there’s no spewing of
diesel. The engines are smaller; they’re compact and efficient.
We can put in a pile two-thirds faster than what a diesel
hammer can,” Larwill said.
There are several different environmental concerns that
contractors can make themselves aware of.
“One of the things that people should be aware off is that if
your piles have a coating and they have to be ground or sandblasted
off, there are fairly strict requirements that you have to
follow,” said Kaufmann.
