Project Profile
Background
The Crater Lake tunnel plug has leaked since its construction (1989). The first
substantial leaks developed shortly after construction in cracks and seams at the plug's
downstream interface. APA hired a contractor to drill several arrays ofholes in the plug
and grout it with cement grout. This procedure stopped most of the leaks.
In 1994, a small leak developed from under the sill of the tunnel plug bulkhead door.
This leak gradually worsened until it was spraying water up against the ceiling of the plug
access. AP A tried to make minor repairs, but were not successful in stopping the leak.
Flow from this leak was estimated at around 60 gpm.
In 1995, a leak appeared from the 5 inch conduit carrying the two 4160 volt power cables
through the plug. This conduit travels approximately 200 feet up the plug to a stainless
steel pull box. The box is filled with and asphaltic filler compound and encased in
unreinforced concrete. This leak worsened in 1996, when pieces of asphalt were ejected
out the end of the conduit. Flow from this leak increased until it was spraying 20 feet
from the end of the conduit at an estimated 300 gpm.
Repair
Revisions to the original repair plans were made when the sill plate and pull box were
accessible after dewatering. The final plan is described below and is shown in the
enclosed drawings.
Access to the plug was minimal because water flowing from the leaks had washed away
large quantities of gravel from the tunnel floor. The project required the mobilization of
several pieces of equipment to the tunnel plug. So, the invert of the access adit had to be
filled and graded prior to the repair work.
At the door sill, five 3 inch holes were cut into the top of the sill plate with a Y2 inch vent
hole upstream and downstream of each 3 inch hole. A fairly large void (up to 6 inches
deep and 8 inches long) was found under each 3 inch hole. All silt, debris, and loose
concrete was removed from each void, and threaded 3 inch couplers were tack welded on
the holes. The grouting operation consisted of screwing a 3 foot PVC standpipe to each
hole and pouring in the grout. The grout was allowed to set before the couplers were
removed and steel plate was welded over the holes. The grout used was Master Builders
Ceilcote 648 Plus. This is a two-part epoxy with a fine aggregate added. It flows into
small cracks better than concrete, adheres to steel and concrete (and everything else),
does not shrink like concrete, and has compressive strengths of approximately 15,000 psi.
The original plan was to cut the lid off the pull box, repair the suspected damaged
communication cable and fill the box full of the same grout used in the sill plate.
However, after dewatering, the integrity of the pull box was found to be a lot worse than
suspected. The concrete cover had been broken, the box completely crushed, the
communications cable severed in two places, and both power cables damaged. This
necessitated a new plan.
The power cables showed damaged to the outside plastic sheath, and a deformation and
cracking of the copper armor. A megger test and de hi-pot test were performed to
determine that the conductors and insulation were intact. The power cables were then
wrapped with high-voltage tape. The communication cable was spliced with two 3M
Scotchcast splice kits. These kits were selected because they embed the splice in a two-
part protective epoxy.
· Both splices in the communication cable, as well as the damaged area of the power
cables, were covered with schedule 40 stainless pipe. The ends of the pipe were plugged
with OZ-Gedney mechanical rubber plugs. Each of the three pipes were then filled with
high-voltage asphalt fill compound. The pipes were then covered with the same epoxy
grout used in the sill plate, and finally, the whole installation was covered with
reinforced concrete.
Results
Inspection after watering up the tunnel showed that the results of this grouting job were
very good. There is a small trickle of water coming from the power cable conduit. It is
estimated to be much less than one gallon per minute (about drinking fountain flow). It is
uncertain where this flow is coming form, but with the excellent seal on the end of the
conduit leads to the possibility that the conduit is cracked in another spot. A possibility
is that the conduit was nicked by the drilling done in the tunnel plug shortly after the
original construction.
The leak at the sill plate was greatly reduced. The only leak remaining in this area is a
small stream of water squirting up at fairly low pressure. The flow is estimated at one
gallon per minute, and is low enough that it may be possible to tap oakum or lead wool
into the leak to reduce or even stop the leak completely.
Interesting effects of sealing the leak at the door sill is how other leaks have appeared in
the plug. Small leaks which were sealed in the original grouting effort have started
leaking again. Water pressure has pushed out the plugs of grout in at least two of the
holes where a urethane grout had been placed.
2
Recommendations
An attempt will be made to plug the remaining leak at the door sill by tapping in oakum
or lead wool. Even if the leak is not stopped completely, slowing it down will reduce
further erosion of the concrete.
The rate of leakage from under the sill will be monitored to ensure stability of the area. A
baseline measurement will come from timing how long it takes for the leakage to fill a
five gallon bucket. Then monthly timings would follow to be able to measure any
changes and determine whether additional grouting is necessary.

Daily Journals
Wednesday, July 9, 1997
Scott Willis, Eric Eriksen, and Sherman Johnson, mobilize to Snett. The Snett
crew had worked the weekend to repair the road in the access adit and station the
compressor and welder there.
Spent the day cutting out the crushed pull box. Were able to finish most of it.
The power cable has been damaged somewhat. One cable shows a "pinch" that
has penetrated the outer PVC jacket and the copper armor. We can't tell if the
underlying layers are damaged. The other cable has the outer jacket worn away
over an approximate 4 foot length, and the copper armor tom away for a 4 inch
length. There is no visible damage to the underlying layer. Our plan is to megger
the cable to see if we can detect any damage to the conductor.
The communications cable is completely severed at both ends of the box. Our
present plan is to add a length of cable to the junction box downstream of the
tunnel plug. Make one of the splices outside the plug, and pull 6 feet of cable
through so that we only have to make one splice in the tunnel itself.
Thursday, July 10, 1997
the megger we rented form Neubauer arrived at the Project. Tom and Ron worked
on meggering the cables. The results of this test were inconclusive. We don't
think the megger was charging the full length of the cable. On the other hand we
didn't detect a ground or short in the first portion of the cable either.
We finished cutting out the pull box. We left the upstream and downstream ends
in case we needed to weld to them. There is still a plug of asphaltic filler
compound in the communications conduit. We need to remove this to pull
enough cable through to make a splice.
Now that we can finally see what the condition of the cables is, we can develop a
plan. If the cables still have their electrical integrity, we will protect the damaged
areas, encase it in steel conduit, fill it with an asphaltic compound, encase that in
grout, and pour reinforced concrete over it alL At the communications cable we
will us in-line splice kits, and protect them with steel conduit filled with asphalt.
Eric and Sherm moved to the sill plate and began cutting holes and cleaning them
out. On cutting in to the sill plate, we found that there is void there. The void is
not quite as large as expected and there are places where it is over 6 inches deep.
There is some loose material in the holes that we are cleaning out.

Scott spent the day showing an insurance guy around the Project.
Friday, July 11,1997
In our final plans we don't need the upstream plate, so we cut it out. We covered
the sill plate so that the Bobcat could run across it without dropping debris into
the holes. We cleaned up in preparation to pull off for the weekend. We also
mixed up the sample of grout to see how it works. The grout is relatively thick,
but it does flow through small holes and cracks.
We made plans to hi-pot the cables Monday. If they pass the hi-pot test, we will
protect the damaged areas and seal them up. If they don't we will have to cut out
the damaged portion and splice in a new section.
Snett personnel will work the weekend to muck out the rock trap in the tunnel.
Monday, July 14, 1997
the rock trap was mucked out this weekend. Sherm, Eric, and Scott returned to
the Project. The weather was foggy, so we didn't get in until10:00 a.m. or so.
Brian, from Gastineau contractors also came out to begin the work on the Long
Lake road. Joe Smith, the other person from Gastineau Contractors will be flying
his own plane out in the afternoon.
The line crew that was supposed to come out and hi-pot the cable in the morning
were weathered out of Snett that morning.
Tuesday, July 15,1997
Hi-potted the cable to 15 Kv. Both cables looked good.
Gastineau Contractors finished clearing the road to Long Lake.
All left the project that afternoon.
Friday, July 18,1997
Scott and four carpenters on site. Carpenters mobilize materials and equipment to
Long Lake. All left that afternoon.
Monday, July 21, 1997
Five carpenters on site. Start working on Long Lake dam.

Tuesday, July 22, 1997
Scott, Eric, and Sherm arrive. Cut back 4" conduit. Weld split pipe on 5"
conduit. Made 4" protection sleeves for splices on communications cable.
Received plugs and asphalt.
Discovered that the piezometer line to surge tank had been damaged. Received
unions to repair it. Repaired that evening.
Carpenters continue working on Long Lake darn.
Wednesday, July 23, 1997
Made splices in communications cable. Covered both splices with 4 inch
schedule 40 stainless steel pipe. For the downstream splice the pipe was welded
to the existing conduit. Plugged the ends with OZ Gedney conduit sealing
bushings. Poured the asphaltic filler compound into each of the three conduits.
Carpenters continue working on Long Lake darn.
Thursday, July 24, 19970 ..
