MEMORANDUM
DATE: March 21, 2008
TO: CEC Board of Directors
FROM: Clay Koplin, CEO
RE: HBC Removal of Intake Structure
The FERC requires CEC to remove the damaged intake structure from the bed of
I3umpback Creek for safety and stability reasons. Furthermore, the structure needs to be
removed as soon as possible to let gravel and cobbles flush down the river and reduce the
excavation required for the new structure. Snow melt in mid to late April will increase
flows in the creek, making the task more difficult and costly, and jeopardizes the Army
Corp permit (to be issued this week) which is based on low flows. Due to the
bentonite/clay seal inside the structure, an erosion and sediment control system of silt
fencing and gabions needs to be installed, and plans filed with the FERC for their
approval. After the intake is removed, this system will be maintained in place to manage
sediment and erosion during construction of the new intake structure. I am striving to
assure that removal of the structure can commence before the next regular board meeting
and am seeking approval now to avoid another special meeting of the Board on short
notice. The work will be competitively bid per CEC policy to local contractors; and
awarded to the successful bidder. It is estimated that the structure removal including
permitting, engineering, and construction tasks is $504,141.
I recommend the board of directors approve removal of the BBC damaged intake
structure for a not to exceed cost of $505,000. This task will be considered as a portion
of the total project cost.
I feel that this task, if pursued immediately and aggressively, can be completed for well
tinder the approved amount, It also sends the necessary message that CEC is proceeding
-_. with our "emergency repairs", and familiarizes the local contractors with the site and
logistics which will help with costs and timelines on the road and new intake structure
work I believe that if accomplished for well under the estimated amount, it will give the
board more confidence in the project process and progress. I would caution the board not
to share approved numbers outside of the board room as it may influence the competitive
bid process by local or outside contactors. This number includes engineering,
-- administration, and agency permitting, so the actual construction component is only a
portion of the total amount. Cost control will be a team effort on this project.

RE: Humpback Creek Proposal of Work
Time & Materials Proposal
We propose to use a landing craft to land on the south side beach at Humpback Creek
with a Hitachi EX270 & make our way up the old cat road until we hit the survey center
line of the new proposed road grade. At this point we will follow the survey line until we
reach the top staging area.
We will utilize helicopters for fuel, hand tools & small equipment.
Crews will get the John Deere running & build gabion weirs.
2 — 6" will be rented from CMI if required by CEC engineers as talked about at meeting.
Demolition of the intake will begin with the EX270 & 4 man crew. When bentonite.level
is reached diversion can be built using 48" HDPE culvert if needed.
CEC project engineers will make the call.
Bentonite will be excavated & placed in super sacks. Demolition can then be finished and
diversion removed and project site cleaned up. Helicopter will fly all misc. tools &
equipment out and excavator will be walked to beach for demob on landing craft back to
town.
