Feds tell Duluth to fix sewers
The EPA orders Duluth and the WLSSD to complete a costly
effort to stop sewage overflows.

No more sewage overflows.
That's the order from the U.S. Environmental Protection
Agency to the city of Duluth and the Western Lake Superior
Sanitary District after years of overflows into the St.
Louis River and Lake Superior.
The order, received Monday from the EPA's Region 5 office
in Chicago, will force the city and WLSSD to spend millions
of dollars in coming years to stop rainwater from leaking
into sanitary sewage pipes.
It's rain water and melting snow that overwhelm the sewage
collection system, sending millions of gallons of diluted
but untreated sewage into the environment at manholes
and pump stations.
After public outcry about multiple sewage spills in 2003,
EPA now is demanding that the city hasten its efforts
to solve the problem.
The city and WLSSD "shall immediately take all viable
and practicable actions necessary to cease and desist
all sanitary sewer overflows from points in their sanitary
sewer system," the 14-page order states.
Jo Lynn Traub, EPA Region 5 water resources director,
said sewage overflows are illegal under the federal Clean
Water Act. Under the order, the city and WLSSD have 60
days to craft a plan to stop the overflows and to submit
a work schedule.
"EPA recognizes that the problems with this system
did not arise overnight, and it will take some time to
fully correct them. This action is the first step in a
long-range solution to the problem," Traub said.
The city already has worked for a decade to stop the
overflows by paying to help homeowners disconnect their
footing drains from the sanitary sewage system. But it
became clear during the past year that disconnecting storm
drains, for which the city has already spent $8 million,
won't solve the problem.
Nearly 3,000 of the city's 25,000 homes have seen their
foundation drains disconnected from the sewage system,
but that work alone "will not get us there on the
schedule laid out in the permit," said Mark Winson,
Duluth chief administrative officer.
So the city now is looking at replacing leaky sewer lines
between homes and streets that serve to funnel clean water
into the sanitary system. The city also might construct
giant storage tanks in key areas to collect sewage during
rainstorms, preventing overflows.
Duluth has asked Minnesota legislators for $5 million
in 2004 to help pay for sewage storage tanks at 52nd and
60th avenues east to hold back overflows during rainstorms
-- about half the cost of the projects.
Solving an even more vexing overflow problem along the
city's Lakewalk could cost as much as $40 million to build
And while the city and WLSSD are seeking state and federal
money to help foot the bill, it's clear it will cost more
in coming years to flush a toilet in Duluth.
"We need to decide what's the best mix... of solutions
to minimize what the cost will be to the rate payer,"
Winson said. "But ultimately, the difference is going
to have to be picked up by the residents of Duluth."
Winson said it's too early to give a total price tag
to fix the problem or to estimate how much sewage rates
will increase to stop the overflow problem.
EPA officials declined to say Monday what will happen
if the city fails to meet any agreed-upon deadline, but
options include steep fines and a moratorium on new construction.
"I don't think it's going to get to that point,"
The new EPA order goes beyond the city and WLSSD's current
permit with the Minnesota Pollution Control Agency. It
demands that the city totally eliminate, not just control,
"That isn't a surprise, but it is different than
what we had been dealing with," said Kurt Soderberg,
WLSSD executive director.
The current state permit requires the problem to be effectively
solved by 2007. It's not clear if the EPA will demand
The city operates most of the sewage collection system
while the WLSSD operates a few main lines and the sewage
treatment plant in Lincoln Park/West End. Homeowners are
responsible for fixing any problems from the home to the
Duluth is one of dozens of U.S. cities that have problems
with sewage overflows during storms. But among cities
that have separate sewage and stormwater systems, Duluth
is among the worst offenders. That's because of the city's
topography -- excess water runs down the hill fast --
and the age of the system.
