Inspection Summary:
This particular Kenametal facility manufactures dry metal powder that is shipped to other Kenametal facilities for the
production of hardened cutting tools like those used for mining or in road excavators. All manufacturing and industrial
processes takes place within the facility. All products, wastes, etc. are either stored within warehouses or in secondary
containment. The silos in the photos contain liquid hydrogen, argon and heptane. The heptane is contained within the silo
that has the secondary containment pit. All internal drains flow to the sanitary sewer.
David is not aware of why the facility was required to apply for an individual permit originally, but he provided a detailed
SWPPP and we reviewed multiple years of stormwater samples during the inspection. The samples values all appeared to
read well below the benchmarks on average. They have been sampling for cobalt, but there is not currently a benchmark. I
do not know if the average value from the samples is of any significance or not. It does appear that there is some detection.
David performs facility inspections monthly. It was visible that housekeeping regualry occurrs in the outdoor areas.
No issues were observed.
The facility produces about 180 thousand kilos of hardened metal powders annually.
