Sludge Watch ==> Milwaukee continues to stuggle with PCB contamination into Milorganite

While the Milwaukee Municipal Sewerage District brags that they can sell
their dried sewage sludge as "Milorganite", the Milwaukee auditors found
that turning Milwaukee's sewage sludge into this 'fertilizer' is the most
expensive disposal method on their list of possible management venues.
Imagine just how much more "Milorganite" is going to cost the taxpayers of
Milwaukee as the lawsuits start and the clean up gets underway.
Meanwhile, the lawyers at Milorganite are lobbying the Canadian government
to relax the Fertilizer Act to give sludge fertilizers easier passage into
this country. With the massive contamination of Milwaukee sewers with PCBs
and the closure of countless parks and school fields with contaminated
Milorganite, you'd think that Milorganite people would acknowledge the
danger posed by their sludge 'product' rather than trying to strip away
regulations that protect the public.
The PCB contents in the land spread Milorganite material went undetected
until after spreading. Who know what other toxins continue to be found in
the sewerage that goes into Milorganite?
In the public interest, and in the name of taxpayer liability, isn't it time
to close down Milorganite?

MMSD may require cities to test pipes for PCBs
Contaminant threatens fertilizer operation

To protect public health and a late-1980s investment of more than $200
million in public funds to upgrade its Milorganite fertilizer production
plant, the Milwaukee Metropolitan Sewerage District might require itself and
each of the 28 communities it serves to test sewers in older industrial or
commercial areas for possible PCB contamination before the communities clean
the pipes.
Sewers in residential-only neighborhoods or sewers built after 1980 - a year
after use of PCBs was banned in the United States - would be exempted from
the testing requirements of an emergency sewer cleaning rule to be
considered this month by the district's policy-setting commission, officials
said.
The rule, if approved, would be imposed for 120 days to allow time for the
district to hold a public hearing on a permanent mandate and prepare
guidelines for cleaning sewers in industrial areas, MMSD Executive Director
Kevin Shafer said. The rule would apply to the district's 300 miles of large
pipes, called interceptors, which collect sewage from the communities. It is
not known what percentage of the 3,000 miles of municipal sewers would be
covered by the regulation.
Milwaukee and most of the communities already have suspended sewer cleaning
in industrial areas in response to the proposed rule, officials said.
Sewer cleaning crews in Milwaukee earlier this summer likely dislodged
sediment contaminated with PCBs from the bottom of two sewers, and that was
probably the source of the chemicals that subsequently contaminated sewage
sludge at Jones Island, a preliminary investigation found.
Sludge removed from the Jones Island treatment plant is dried to produce a
variety of fertilizer products, including Milorganite. No Milorganite stocks
were contaminated, however, because production of the brand-name fertilizer
had been suspended in early June because nitrogen levels in the sludge were
too low.
Dried sludge fertilizer that did not meet Milorganite specifications and was
tainted with the chemicals was spread this summer on 30 public recreational
areas. The district must clean up three Milwaukee Public Schools' sites by
removing the top several inches of soil. The work could begin Monday or
Tuesday.
Sewage sludge produced daily at Jones Island continues to be contaminated
with excessive concentrations of PCBs, preventing MMSD from resuming
fertilizer production. More than 1,600 tons of the dried sludge made since
late June is tainted with so much of the chemicals - more than 50 parts per
million of PCBs - that it will have to be disposed of at a special
toxic-waste landfill near Detroit.
The district expects to begin trucking the sludge to Michigan beginning
Sunday or Monday.
The ongoing PCBs problem will cost district taxpayers more than $1.25
million before it is resolved this fall.
"We need to minimize the risk of this occurring in the future," Shafer said
in explaining the need for the emergency rule.
Banned in the U.S.
Use of PCBs in the U.S. was banned in 1979. The compounds had been used as
insulators in electrical equipment and mixed in lubricants, adhesives, inks,
carbonless copy paper, asphalt and other products.
Mike Pertmer, West Allis director of public works, said that his city's
sewers do not pose much of a chemical risk to MMSD because they have been
cleaned regularly since the early 1980s.
"We clean our sanitary sewers every 12 to 16 months," Pertmer said.
"Whatever might have been in the sewers 20 years ago or longer would have
been removed long ago."
West Allis also videotapes its sewers at least once every decade and would
know if sediment or other debris had accumulated in any pipe, he said.
Wauwatosa has a two-year cycle for cleaning all sewers and likely is not a
risk to MMSD, city engineer Bill Wehrley said.
Even so, Wauwatosa and West Allis plan to comply with the rule, the
officials said. Both have delayed cleaning sewers in industrial
neighborhoods for now.
The two cities also are preparing maps required by the rule to show the
location of pre-1980s industries that might have used equipment or products
containing PCBs, as well as businesses that might have recycled chemical
waste or equipment contaminated with PCBs in recent years.
Milwaukee, too, is at work on such a map, city engineer Jeff Polenske said.
There is no estimate at this time of the number of miles of city sewers in
which testing will be required before cleaning, he said.
Milwaukee and MMSD lag behind the other municipalities in cleaning their
sewers, however. Before the district's deep tunnel wastewater storage system
was built, it was not possible to shut down most of the city's combined
sewers or the district's regional collector sewers for cleaning, officials
have said.
Attempts to clean out two neglected, aging sewers this summer unwittingly
released a cascade of PCBs that continue to cause problems at Jones Island.
One is a Milwaukee combined sewer along N. 31st St., between W. Auer Ave.
and W. Townsend St. The other is a large MMSD interceptor sewer that runs
along W. Hampton Ave. to the Milwaukee River and down Humboldt Blvd.
Crews were cleaning both sewers in mid-June, and the concentration of PCBs
in sewage sludge on Jones Island increased to unhealthful levels within
days.
Cleaning of those two sewers has been suspended indefinitely.
