EPA OK's DOW SOIL DISPOSAL REQUEST

U.S. Environmental Protection Agency (EPA) Region 5 has approved a request by
Dow Chemical Co. to dispose of contaminated soils from its Midland, MI, facility at
the company's Salzburg hazardous waste landfill near the Midland plant.

The soils will come from excavations to replace part of an aging 13,600 ft tile system
that protects the Tittabawassee River by collecting contaminated ground water and
routing it to Dow's wastewater plant, where it is treated before being discharged into
the river. 

Some 100,000 cubic yards of soil contaminated with dioxins and furans will be
removed.  These chemicals are byproducts or impurities formed during the
manufacture of chlorinated phenolic products, such as 2,4,5-trichlorophenol (2,4,5-T)
and pentachlorophenol herbicide.

Soils with dioxin concentrations greater than 1 part per billion (ppb) but less than 50
ppb will go to the landfill.  But soils with dioxin concentrations greater than 50 ppb will
be treated at one of Dow's on-site hazardous waste incinerators.

EPA has approved the Dow request because:

* It will speed-up replacement of the ground water collection tile system that
protects the Tittabawassee River.

* It will provide extra environmental protection by allowing more flexibility in
construction methods and materials, thus making the collection system more
durable and effective.

* It will eliminate the need for long-term storage of contaminated soils at Dow, as
well as the need to incinerate large amounts of low-level  contaminated soil.

* Disposal at Salzburg Landfill will protect human health and the environment.
