Hazardous Waste Storage Permit September 2008
Email Notification to Mr. Jeff Vandel January 08, 2010
Dear Mr.Downs:
On January 8, 2010 notification was given by email to Mr. Jeff Vandel of a spill containing
perchlorate. Our Hazardous Waste Storage Permit in Module I, I.T.5. requires that a report be
submitted within 15 days.
During the month of December, a culinary water line and a fire suppression line containing
culinary water, fi-oze and broke in a building that is currently not in use. The onsite fire
department responded to the alarm and shutoff the water. The water had spilled onto the floor
and then flowed into a sump. A small amount of water flowed out ofthe door onto the
asphalt forming a small pool of frozen ice. This frozen pool was sampled and found to
contain a perchlorate level of 24.6 mg/L. Judging from the size ofthe frozen pool on the
asphalt it did not appear to be a large quantity of water released.
Following the notification on January 8^*^ a soil sample was collected and analyzed from a
drainage ditch located just off of the asphalt pad. This sample reported a perchlorate level of
2.2 mg/Kg. This level is below the residential Regional Screening Level (RSL) of 55 mg/Kg.
It does not appear that the water released from the building resulted in a large quantity of
water released to the environment. This small pool of ice is still frozen and efforts will be
made to chip it up and remove the contamination and then treat it at our M-705 facility.
Please contact me if you have any questions concerning this report. My telephone number is
[phone] or you can contact Blair Palmer at [phone].
Sincerely
