Dear Mr. Noland:

ENV. MANAGEMENT
FAYETTEVILLE PEG, OFFICI
This letter documents the telephone call I made to Tommy
Stevens early yesterday afternoon concerning aspill of an
aqueous inorganic solution which occurred Yesterday morning from
Fayetteville Works of DuPont.
At approximately 1.0 AM, a nipple on a Kathobar
humidification control unit on the roof of our Butacite@
Manufacturing Building broke off due to corrosion. This resulted
in the loss of the inventory of that unit --70 gallons of 35%
Lithium Chloride and less than 0.5 gallons of 35% Lithium
Chromate corrosion inhibitor to the cooling water/stormwater
discharge (002). On a dry weight basis, this is equivalent to a
discharge of 244# Lithium Chloride and less than 2# Lithium
Chromate.
Lithium Chloride is not a CERCLA reportable material.
Lithium Chromate is a CERCLA material but with a reportable
quantity of 10#; so no CERCLA report was necessary or
appropriate. The material is completely soluble in water and
should have been totally undetectable and inconsequential to
river quality. We reported to your office in accord with our
policy and implied permit requirement to report whenever we
discharge any non -declared material in a significant quantity
regardless of toxicity or impact. For approximately one hour, our
outfall should have been characterized by the following
abnormalities: 12 ppm lithium ion, 60 ppm additional chloride ion
and less than 0.2 ppm chromium VI.
Followup involves additional inspection, preventive
maintenance and evaluating the feasibility of localize& conta nment
Please call me if additional information is req
