Hi Matthew,
Currently, Colowyo is proposing to incorporate wells POC-2 and POC-10. These wells are pre-existing and under TR-148,
Colowyo is not proposing to construct or install new wells. With that said, there is potential that locations may change
during the TR-148 adequacy process. However, this is unlikely as the Division and the Colowyo Mine have been in
preliminary meetings and discussions regarding the proposed well locations and monitoring plan. If any changes
regarding location or the construction of new wells, the Division will ensure this information is passed along to the
necessary parties for review.
Sincerely,

Hi Zach,
Thank you for providing the information. Just to confirm, TR-148 does not propose installing new wells and will only
use POC 2 and POC 10 for a well monitoring program? The documentation in your system suggests that the applicant
will construct two new wells near the previously constructed POC 2 and 10 wells. Is this the case?
Regards,

Mr. Marques,
Currently the Division does not have any aerial images of the proposed well areas. The proposed wells are outside of
the currently approved permit boundary. With that said, they are pre-existing wells that have already been
constructed and just being proposed to be incorporated into the permit as part of their groundwater monitoring plan in
the Colowyo Mine permit. As part of the Division's adequacy review process, the Division will request any photo
documentation that is available by the Colowyo Mine. Additionally, the Division can forward documentation of the
area from future inspections.
Please see the attached Figure showing the location of the proposed wells (POC-2 and POC-10) as well as the
construction reports which have the associated coordinates. If you have any questions, feel free to contact me.
Sincerely,

Hi Zach,
started to review the submission for TR-148. I was wondering if you could provide a close-up aerial image of the
proposed well locations or at least coordinates for the proposed well locations. This will help me understand the
area of potential effects.
Thank you,
