DAMAGED TROXLER MOISTURE DENSITY GAUGE
"Based on discussion between field personnel (authorized nuclear gauge user) and [the licensee], the rubber-tire wheels of a piece of construction equipment ran over [a Troxler] gauge. [The licensee] personnel, with assistance from the contractor, immediately cordoned off the area so that the appropriate steps could be taken to access the situation.
"Based on the pictures that were sent to [the licensee] and conversations with the field personnel, [the licensee] does not believe that the gauge was damaged severely enough to cause a radiation leak from the gauge.
"The source rod was inside the inner protective housing (i.e. shield) when it was damaged. It appears that only the outer plastic casing was cracked and the index rod was snapped. The inner protective housing (i.e. shield) protecting the CS-137 source and the Americium 241 source protective cover appear to still be intact. The source rod was not bent. The sliding block at the bottom of the gauge is fully closed.
"Since the index rod locks the source rod in place, [the licensee] instructed field personnel how to temporarily restrain the index rod and therefore keep the source rod inside the protective shield. After properly securing the source rod, [the licensee] had field personnel place the damaged gauge inside the yellow DOT transport box. The transport box / gauge was then properly secured inside a large steel container (dedicated to [the licensee]) at the construction site. Only [licensee] personnel have access to the steel container.
"[The licensee] sent down a radiation meter to field personnel via FedEx overnight. The radiation meter only showed that the radiation level immediately next to the gauge was 4 mrem. The measured radiation level several feet away from the gauge was about 0.12 mrem. No radiation was measured outside of the steel container.
"[The licensee has] scheduled for the gauge to be picked up on Thursday by [licensee's] repair service firm. The repair service will perform their own leak test in the field prior to transporting the gauge back to their shop.
"Gauge Make/Model: Troxler 3440
Gauge Serial Number: 28929
Langan Gauge No.: #22
Nuclide (Serial No.): AM-241:BE (47-25121), CS-137 (750-3218)"
Typical Troxler gauges of this series contain a 8 mCi Cs-137 source and a 40 mCi Am/Be source.

OFFSITE NOTIFICATION DUE TO POSSIBLE RELEASE OF FUEL OIL TO THE ENVIRONMENT
"A notification to the Tennessee Department of Environment and Conservation (Chattanooga Field Office) was made at 1134 [EDT], 29 June 2009, pursuant to a failed pressure test on an underground section of diesel generator fuel oil transfer piping. This section of piping is not required for operability of the emergency diesel generators. The section of piping has been isolated. Efforts are in progress to determine if fuel oil was released to the environment."
The licensee notified the NRC Resident Inspector.
* * * UPDATE AT 1642 EDT ON 07/23/09 FROM CALVIN FIELDS TO S. SANDIN * * *
During work to remediate the above concern, an offsite notification was required as described below:
"A notification to Hamilton County Air Pollution Control Bureau was made on July 23, 2009 at 1505 in accordance with the Site's Annual Asbestos Removal Notification . Work was being performed on buried piping when the pipe wrapping was determined to contain asbestos. Work was stopped and the work area controlled by site work documents."
The licensee informed the NRC Resident Inspector. Notified R2DO (Vias).
