CASE SUZ-W-21-01
FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF
Preparer/Sponsoring Witness: C. Cooper IN. Crofts
REQUEST NO. 1:
Regarding the non-potable lines encountered during Western's excavation for the
Hangar 0 project:
a) What is the purpose of these lines and whom do they serve?
b) Who installed these lines?
c) Were these lines installed before or after the Suez main on Boeing?
d) Please provide a drawing showing the location of these lines. Are they above or
below the Suez main?
RESPONSE NO. 1:
The non-potable line addressed here is a new fire supply line from Western's existing
fire flow tank to the new and existing Hangar buildings. Please see attachment "PR 1
Exhibit A.pdf' for a map showing the new fire supply line and the areas of concern
related to potable water lines.
a) The new fire supply line serves Western Aircraft and supplies their fire suppression
systems in both the existing hangar and the new hangar. The former fire supply line
that served just the existing hangar (which SUEZ understands has been abandoned) is
also shown on Exhibit A for information purposes.
b) Western Aircraft installed the new fire supply line.
c) The new fire supply line was installed after the SUEZ main on Boeing. The SUEZ 8"
PVC line south of the existing Western Aircraft hangar was installed in 1990. The new
fire supply line was installed by Western Aircraft in 2020.
d) Please see the attached exhibit "PR 1 Exhibit A.pdf' for horizontal locations of the
new fire supply line. Known areas with separation distance issues include the
following.
Location 1 -An existing potable water main from the SUEZ water main in Kennedy
Street that is used to fill the existing Western Aircraft Fire Flow Tank now has the new
fire supply line installed next to it. These two lines do not meet the potable / non­
potable separation requirements of the Idaho Department of Environmental Quality
(IDEQ) (6' minimum separation, with the water line at least 18" above the non-potable
line). Potential Fix -A backflow prevention device installed on the existing potable
water main immediately adjacent to the connection to Kennedy would make it so both
the existing potable water main and the new fire supply line are both considered non­
potable, and then no separation distance would be required. Alternatively, the
separation distance could be fixed to meet IDEQ requirements.
Location 2 -There appears to be 7' separation between the new fire supply line and
the existing SUEZ potable water main in the old Boeing Street right of way. This meets
the minimum 6'IDEQ horizontal separation distance requirement. It is not clear if the
fire supply line was also installed at least 18" lower than the SUEZ water main (another
IDEQ requirement when there is not a minimum 10' separation distance).
The separation distance requirements are shown in the following figure from the Idaho
Standards for Public Works Construction.

FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF

REQUEST NO. 2:
Regarding the sewer line encountered during Western's excavation for the Hangar 0
project:
a) Whom does this sewer line serve?
b) Who installed these lines?
c) Were these lines installed before or after the Suez main on Boeing?
d) Please provide a drawing showing the location of this line. Is it above or below
the Suez main?
RESPONSE NO. 2:
SUEZ is not aware of an existing sewer line that was encountered during Western's
excavation. Please see the attached "PR 2 Exhibit B.pdf' that shows the new sewer
lines installed by Western.
a) The two new sewer lines installed by Western Aircraft serve the new Hangar 0
and the existing Western Aircraft Hangar.
b) Western Aircraft installed the two new sewer lines.
c) The two new sewer lines were installed after the Suez water main in Boeing. The
SUEZ water main was installed in 1990, the two new sewer lines were installed
in 2020.
d) Please see the attached "PR 2 Exhibit B.pdf' and "PR 2 Exhibit C.pdf'.
Location 1 -The new sewer lines are below the water main, but are not the
minimum 18" below the existing water main required by IDEQ, nor are they
constructed of water class pipe. Please refer to the separation distance diagram
from ISPWC included in the response to Discovery Request No. 1.
Location 2 -The horizontal separation distance between the new sewer line and
the existing SUEZ water main in Cessna Street (installed in 1978) does not appear
to meet IDEQ requirements.
