potential setback for the beleaguered natural
gas pipeline.
A permit for the 303-mile (488-km) proposed
pipeline was opposed by environmentalist
groups after the West Virginia Department of
Environmental Protection (WVDEP) found 100
water-quality and sediment violations.
During arguments at the 4th U.S. Circuit Court
of Appeals, one judge from the panel asked
WVDEP to explain how further construction
guidelines address the pollution concerns.
" There's no question you have new
conditions, what you don't have is an
explanation as to why those conditions are
specifi cally tailored to address past problems, "
Judge James Wynn said.
In previous challenges, the 4th Circuit
Court had vacated key approvals from federal
agencies needed for the pipeline to cross a
national forest.
US Justice Department Sues
Idaho City over Water Pollution
The federal government is suing a small
Idaho town near Grand Teton National Park
for dumping toxic waste from its sewage
treatment plant into a stream that feeds
several scenic rivers in the region.
The U.S. Department of Justice fi led
the lawsuit in Idaho's U.S. District Court,
contending the city of Driggs violated the
Clean Water Act by dumping effl uent with
too much e. coli and ammonia or otherwise
violated wastewater permit rules more than
2,600 times over the last seven years.
The effl uent was released into Woods Creek,
which fl ows into the Teton River, Henry's Fork,
the Snake and Columbia Rivers on its way to the
Pacifi c Ocean. The Teton River and Henry's Fork
are renowned fl y-fi shing locations, drawing
anglers from around the world. The violations, if
proven, could put the city of about 2,100 people
on the hook for more than $160 million in fi nes.
In written statement, the city of Driggs said
the lawsuit was a positive development because
it will allow the EPA and city offi cials to work
together to come up with solutions.
" Although it seems scary to be sued by
the Department of Justice, it's actually an
opportunity to receive support and resources, "
from the federal government, Driggs Mayor
August Christensen wrote in the statement.
Enbridge Approves Expansion of
Southern B.C. Pipeline System
Enbridge sanctioned an expansion of the
southern segment of its British Columbia (B.C.)
pipeline system, a project that would cost up
to US$2.65 billion (C$3.6 billion), after strong
demand from crude oil producers.
In a separate move, the company launched
an open season on the northern segment of
the B.C. line. Interest in the open season would
determine whether Enbridge launches a $1.4
billion (C$1.9 billion) expansion of that line.
Enbridge said the T-South expansion of its
B.C. pipeline system, which runs from near
Chetwynd and extends south to the CanadaU.S.
border at Huntingdon-Sumas, will add 300
MMcf/d (8.5 MMcm/d) of capacity.
The expansion of the T-North segment
would boost capacity by about 500 MMcf/d
(14 MMcm/d). T-North connects the Fort
Nelson area to the T-South segment and to
interconnecting pipelines at the B.C.-Alberta
border on the east.
Enbridge expects the T-South expansion will
be in service in 2028, while open season for
T-North is expected to end Jan. 10, 2023. UC
