Army: Waste to be treated on site
By Frank Lockwood

HERMISTON - The Department of Environmental Quality will seek
permit
modifications "dovetailing" with the Army's reassurances
that a liquid
hazardous waste, called brine, will be treated on site at the
depot - not
shipped to Washington or elsewhere, a DEQ spokesman says.
Critics have long worried that the incineration of chemical
weapons at
Umatilla would create amounts of liquid waste too great or too
toxic to be
processed using BRA, or the Brine Reduction Area systems, and
that Umatilla,
like Tooele, Utah, would abandon plans for using BRA technology,
in favor of
shipping the material to hazardous waste sites, leaving a legacy
of
contamination.
But plans to operate the Brine Reduction Area have not changed
for Umatilla
Chemical Agent Disposal Facility, regardless of what may be done
at other
chemical agent disposal sites around the country, Umatilla Chemical
Disposal
Facility Project Manager Don Barclay said at Thursday evening's
meeting of
the Citizens Advisory Commission.
"Each site is an individual site with individual needs,"
said depot
spokeswoman Mary Binder.
Mid-August news articles had suggested the Army might renege
on its plan for
handling waste water on site at Umatilla, instead trucking it
off site,
perhaps through Tri-Cities en route to Kent, Wash. Presently,
UMCDF is
temporarily sending brine to Kent, during surrogate testing, because
the BRA
is not yet up and running.
As early as May, environmental groups said they feared that
the
transportation of liquid wastes would not stop with the end of
surrogate
burn trials at the depot, and that the Brine Reduction Area technology
would
be left idle.
Joseph Keating, on behalf of the group, GASP, testified during
a July 26
hearing before the Environmental Quality Commission, saying, "We
agree with
the Umatilla Tribes' concern about the Army plan to eliminate
the Brine
Reduction Area."
The Brine Reduction Area was built to process liquid wastes
generated by
incineration at UMCDF. The BRA reduces wastes to a salt-like substance.
According to GASP, the Army has known about BRA "problems"
since testing and
operations at Johnston Atoll and Tooele, Utah incinerators. If
the Army did
discontinue use of the the BRA, it would be the second major part
of the
Umatilla incinerator to be abandoned, the first being the dunnage
incinerators.
Dunnage incinerators were originally planned for disposing
of such things as
wooden pallets, but the Army later reported a plan to modify other
incinerators to handle that waste. Army spokesmen say they found
better ways
to treat the dunnage. Detractors claim the "DUN" was
simply "inoperable."
Be that as it may, Wayne Thomas, DEQ program administrator, said
Thursday
that his agency will seek a permit modification to make it clear
that the
liquid brine waste is to be treated on site, not shipped away,
and PMCD's
site project manager Don Barclay said the Army had already hired
the crews
to operate the facility.
Confusion may have arisen because of BRA decisions at other
chemical weapons
disposal sites, Barclay said, but those decisions do not change
the plan for
UMCDF.
Concerns increased when Barclay could not "absolutely
promise" that no
liquid brine would ever be shipped off site at UMCDF once surrogate
burns
were complete and real agent incineration had begun.
Unforeseen events could eventually dictate off-site disposal,
Barclay
admitted, but that is neither the plan nor the intent.
If the incinerators generate more waste than can be stored
and treated at
the depot, however, under the present permits the incinerator
operators
might, indeed, be able to seek another alternative. In Tooele,
the Army
made the decision to ship brine water off site, because using
the BRA system
was considered ineffective and costly.
Binder said that some wastewater has been processed at Johnston
Atoll,
however and that this is not new technology, a claim that critics
dispute.
The Umatilla facility does have double the storage capability
of Johnston
Atoll - four 40,000-gallon tanks to JA's two, and three BRA driers
compared
with JA's two.
"Based on all that we know, we believe that we will be
able to" process on
site all of the waste water brine that UMCDF generates, by using
the BRA
facility, Binder said.
