Dear Ms. Rauh: |

Re: Haney Main No. 3 - Stage II
Pitt River Crossing

We write regarding the subject project with particular reference to our upcoming marsh
restoration program scheduled to be completed by District forces and our environmental
consultants. Specifically, we seek your formal approval for the use of “scare cannons” iogether
with the noise levels associated with this proposed marsh protection scheme.

As part of the overall FREMP approval to construct the subject project within code red
habitat, this District was obligated to enter into a legally binding Habitat Compensation Agreement
with the Department of Fisheries and Oceans. This agreement states that this Disuict is
responsible for complete and expedient recovery of the marsh area and long term monitoring. We
have already invested considerable capital and resources to fulfil our legal commitment and we
must take all reasonable precautions to ensure that the specified recovery of marsh plants will be
achieved.

Part of the restoration work mentioned above includes spreading of previously stripped
original marsh sediments on bota foreshores of the Pit River and subsequent selective planting
of seeds and cultured marsh seedlings to best achieve original plant densities. In order to increase
the chance of sccessful marsh restoration, ferra Lotic Resources Ltd. has recommended that
“scare cannons” be placed on each foreshore to protect the rhizomes. seeds and new plant material
from being destroyed by various predators. purticularly geese. Past experience by our consustcnts
in arcas where this form of protection was int used indicates that rapid and complete destruction
of the restored areas has resulted.

Specific detail with respect to our proposed use of “scare canrons" i: summarized on page
