Independent Review Completed of
Asquith Storage Project Water Management
TransGas today welcomed the public
release of an independent review into water management
at the Asquith Natural Gas Storage Development Project,
located west of Saskatoon. The review, conducted by Harm
Maathuis of the Saskatchewan Research Council (SRC), was
contracted by the Saskatchewan Watershed Authority (SWA),
in consultation with a local citizens' committee.
To enable the study, TransGas advanced a
three-month planned shut down of cavern-washing
operations at the Asquith Storage Project on December
13, 2004. Since that time, water levels at the TransGas
source wells for the project have recovered more than 11
metres. Water level monitoring continues at 30 measuring
points in various locations in and around the pumping
area. Near-surface, Tessier, and Tyner Valley aquifer
measurement data continues to be collected from
electronic data loggers by TransGas and shared with the
Watershed Authority, the Saskatchewan Research Council,
and the local community.
"We welcome the completion and public
release of the SRC Report," said Daryl Posehn, Senior
Vice President, TransGas. "We will need time to fully
study the recommendations contained within the document,
however, it appears the independent review confirms our
own analysis that there is sufficient water in the Tyner
Valley Aquifer to sustain this project, and that
TransGas pumping is not contaminating water."
The Saskatchewan Research Council Report
identifies and concludes the following:
There is no evidence that TransGas
pumping has changed groundwater quality in the Tyner
There is no evidence that water levels
in near-surface aquifers in the Dunfermline area
have been affected by pumping associated with the
TransGas may resume pumping for the
Asquith Project at the licensed rate, provided the
water levels in monitoring wells located in the
Tyner Valley and Tessier aquifers do not drop below
the top of both aquifers.
As per the terms of its water-use
licence, TransGas should perform mitigation work for
private wells adversely impacted by pumping
associated with the storage cavern-washing process.
"We look forward to the final decision
by the regulator, the Saskatchewan Watershed Authority,
on TransGas continuing work on this project under the
terms of our water-use licence," Posehn concluded.
The Asquith Storage Project was
initiated in 2003 and is critical to meet growing
Saskatoon area winter natural gas requirements.
