Ms. Wastler,
Thanks for verifying that you received the information. I have spoken with Gautam Sen, Manager Licensing, this
morning. He will ensure that Bob Hammond loads the data in the NEI spreadsheet. Bob already had the password for
access. Bob is working nights to support our refueling outage, so it may not be updated immediately.
Will you be receiving the information from the Website in the future, or would you like us to send any future positive
sample results to this e-mail address also? We understand that submittal of the information is voluntary and doesn’t
constitute a notification.
Thanks,
Tammy Jensen

Ms. Jensen
Thank you for the information.
For further reference, NEI is now collecting the information on radiation levels at US nuclear plants from
Fukushima. They have developed a password protected database where NPP’s can enter this data at
http://environmental.nei.org. I believe you will need to contact Ralph Anderson at [email protected] to get a
password. Once you have the password, you can enter the information gathered at Wolf Creek into the database. I
would appreciate it if you could pass this information on to the appropriate staff at Wolf Creek.
Again, thank you for contacting us in this regard.

I spoke to Bobby Eid on the phone this afternoon and voluntarily provided the following information. As we discussed,
this activity was verified to be coming from a source outside of Wolf Creek. The environmental air sampling data was
obtained from Bob Hammond who is copied on this e-mail in the event you have further questions. The water sampling
data was obtained by the Chemistry department. I’m the contact for that data. I am still working on the uncertainties. I
chose to send this data that I have now.
Environmental Data:
Lake surface water was sampled on 3/28 non-detectable for 1-131
Air Samples pulled on 3/14 & 3/21 non-detectable.
But on 3/28 had detectable 1-131 on Air Samples:

If there’s anything else we can provide please let Bob or I know.
