Good Afternoon,

I apologize for having contacted UMA directly, hopefully this hasn't
caused undo complications.

I have performed a review of the Fox-5, Broughton Island DEW Line site
water license application.  Based on my experience with contaminated
site management and clean-up, including having worked at a Pole Vault
site, I feel that the document is thorough and complete in all respects.

The only concerns to be expressed are very minor.  These are:

1.  Road Construction and Maintenance

Often, when mobilizing operations and when performing preliminary road
maintenance, it is customary to dig drainage ditches adjacent to
roads--this particularly being the case when the early summer thaw
occurs. Drainage is normally to natural watersheds.   Could the engineer
ensure that run-off from contaminated zones is prevented from  mixing
with this flow.

Note:  I believe that Section 4-3 of the document partially addresses
this concern.

2.    PCB Contaminated Paint Landfilling

I understand that PCB contaminated paint is to be landfilled and that
amendments to the EPA will enable this.

I would presume that such landfills would be closely monitored to
determine if they are "secure" relative to
preventing the migration of PCB leachate.

3.    Resident Engineer

Sometimes (although I'm not suggesting that this would be the case at
Fox-5), maintenance workcrews are mobilized early in the season to
perform camp set-up, and are not accompanied by an "environmental
specialist".  To ensure that all work is carried-out in accordance with
the plan, I think that we'd agree that an environmental specialist
should be on site at all times.

I thank you for having provided the opportunity to review this excellent
and informative document.  In my opinion, and assuming that this plan is
followed without significant deviation, a more detailed review is not
warranted.

Please contact me if you have any questions.
