(2006) Corridor Resources BJ Services radioactive frac fluid spill - Penobsquis, NB (article below)
In 2006 there was a Frack spill in Penobsquis, with radio active tracer. The following links will connect you to the PDF’s of the document that Corridor Resources put in the mailboxes of local Landowners and concerned Community members:

a few key quotes from the company documents linked above:
"On August 23, 2006, Corridor had an accidental release of frac fluid (water, methanol, and small amounts of various environmentally friendly chemicals) and sand that included trace amounts of low level, short half-life radioactive material...."
"...the Protechnics engineer who works with this radioactive material for a living is exposed to less radiation than an individual who smokes 11/2 packs of cigarettes per day. It is also important to note that the engineer requires no additional protection clothing...."
"...there is no chance of contamination of any fluids, including groundwater." - in my view, that is mighty arrogant, and impossible for anyone to truthfully claim, even a frac'er
"The BJ Services frac'ing equipment was in the final stages of the stimulation operation when a washout of a segment of the frac iron occurred (piping between the pump trucks and the wellhead - see attached pictures)."
"There were no RA tracer beads found outside the lease area." - ah, but did they look, and if they did, how did they look? the radioactive material is tiny, and would not be easy to find. did the company use looking techniques to ensure not finding any? That seems to be the Frac'ing Way.
"It was estimated that 2-4 m3 of frac fluid and 600 - 1200 kg (200 - 400 litres) frac sand was released...." - estimated, and by the company no less.
"The main cause for the incident was the erosion of the "Y" on the frac iron at the point of high velocity and a change in direction of the sand laden fluid stream. The root cause for the failure of this piece of equipment was the frequency of inspection on this equipment."

HANDLING OF RADIOACTIVE FRAC SAND REGULATIONS
The Canadian Nuclear Safety Commission regulations for disposal of sand labeled with a radioactive prescribed substance are as follows:
“Contaminated sand to be buried at the worksite under at least 30 centimeters of soil provided that the specific activity is less than 370 kBq per kilogram of sand.”
“Any other waste disposal method will require specific written approval to the Canadian Nuclear Safety Commission.”
INTERPRETATION
The above regulation refers to “370 kBq of activity” which is the equivalent of 10 microcuries (uCi) of Iridium 192, Scandium 46 and Antimony 124 per kilogram of frac sand. This amount translates into 10 millicuries per tonne of sand which is considerably higher than the amount injected per tonne (1 mCi/Tonne).
CONTAMINATION MONITORING
Returned sand can be assumed to be contaminated and buried as per instructions below under “Burial of Sand”
R.A. Tracer will return to the location to monitor returned frac sand, prepare a contamination survey report and provide instructions on the steps that must be followed to safely satisfy regulation requirements. An additional fee will apply for this service.
All monitoring performed by R,A, Tracer will be with the use of a Ludlum pancake monitor. The following calculations have been made for this specific instrument to correspond with necessary actions that need to be taken. The recorded level and action required are as follows:
LEVEL RECORDED ACTION REQUIRED
0-200 counts per minute Normal disposal method
200-15000 counts per minute Burial of sand on lease
Over 15000 counts per minute R. A. Tracer will contact C.N.S.C. for instructions
BURIAL OF SAND
Once the sand has been recovered in it’s entirety, the oil company must request that R.A. Tracer monitor the returns to establish the level of contamination and supervise the cleanup to satisfy CNSC regulations.
The following actions should be taken to limit the amount of hydrocarbons in the sand to be buried:
Pump a sufficient amount of water into the tank to displace the hydrocarbons out of the sand.
With the use of a vacuum truck , skim the hydrocarbons out of the tank. Care should be taken to ensure that none of the sand is inadvertently picked up.
Dispose of the hydrocarbons in normal fashion.
The sand/water mixture can now be removed from the tank and buried on the lease. The pit for burial should be excavated first and be deep enough to allow a minimum of 30 cm. of soil cover. The sand can be removed with the use of a vacuum truck or manually shovelled into a pit. The following safety tips should be adhered to during this operation:
During clean-out:
Wear protective clothing (gloves, coveralls and boots).
Cover all open skin, abrasions and cuts.
Keep hands away from mouth and nose (no smoking/eating).
Avoid spreading contaminated sand around lease.
Following clean-out:
a. Rinse tools used in clean-out with water.
b. Dispose of gloves used in clean-out.
c. Wash hands in warm soapy water.
(2006) UNDER NO CIRCUMSTANCES CAN THE CONTAMINATED SAND BE TAKEN TO A RECYCLING FACILITY.

QUOTE: “A spokesman for the commission said the company stated that it had disposed of the substance properly, but it hasn't verified this claim by visiting the site.”
A resource company says it has cleaned up 3,000 litres of material containing a low-level radioactive substance it spilled while drilling for natural gas in the Sussex area in August.
The material that Corridor spilled is called frac sand and is used to fill rock fissures when drilling for natural gas. Frac sand contains some low-level radioactive isotopes.
The spill occurred Aug. 23 at a drill site on land belonging to a family in Penobsquis, said Corridor president Norm Miller.
"It was cleaned up immediately under strict supervision by the Environment Department and no risk of any significance to any personnel," said Miller.
The company buried the material temporarily on another landowner's property, he said.
According to federal regulations, the frac sand must be buried under at least 30 centimetres of soil to be neutralized.
Woman says waste dumped in open pit
However, Beth Nixon, who lives nearby, said the company didn't dispose of the frac sand properly, and instead threw it into an existing open pit. "It's not buried because I've never seen this pit any deeper," she said. "There is a little bit more sand in it at one end than there had been previously, but I can't see that there's been any substantial change."
An official with the Department of Environment said it has never had to deal with a radioactive spill before. It has handed the case over to the Canadian Nuclear Safety Commission.
A spokesman for the commission said the company stated that it had disposed of the substance properly, but it hasn't verified this claim by visiting the site.
