SUBJECT: The Armory -- Phase II Environment Assessment Cost
Jim, attached is Morrison Maierle's quote for conducting a Phase II EA on the Armory site. As
the letter states, the estimate is given due to needs identified in the Phase I EA as well as the
anonymous source of historic operations at the site. I did not see this letter until very late in the
day, Friday, April 20, 2006. Since the Hilton Inn is on the agenda for Council Workshop on
Monday, April 24th, I thought you might want to advise the council then as to the need to
proceed with the Phase II study. While Council stated they did not want you to come back to
them for funding any construction costs on the site, I believe this is a totally different situation
and the City will be responsible for conducting the Phase II.
In a previous conversation with Charlie Harball, he indicated that the City would more than
likely look to the National Guard to compensate it for any remediation costs we might have to
expend prior to disposing of the property.

Dear Ms. Moyer:
At your request, the following is a summary of environmental testing proposed at the
Kalispell Armory site to determine whether there has been a release of petroleum
products, chlorinated solvents or heavy metals associated with the historic activities
reported at the site. Based on the Phase I EA performed by Morrison Maierle, Inc. in
March 2006 and the included anonymous source of historic operations at the site, the
following areas of concern and proposed method of testing are identified in the table
below.

As this table indicates, it is proposed that two deep monitoring wells be installed that at
this time to evaluate the potential for chlorinated solvents located in the groundwater
below the site. Since chlorinated solvents like PERC or its daughter products like vinyl
chloride have a specific gravity greater than 1 these constituents can be located below
the water table of the aquifer. In addition to the two deep monitoring wells, four
additional shallow monitoring wells will be installed so they are screened through the
CADocuments and Settings\mbrooke\My Documents\Proposals\106 Moyer.doc

water table for analysis of petroleum hydrocarbons. If contaminated soil is encountered
during drilling, soil samples will be collected from these shallow monitoring well
locations as well. Finally, anecdotal information indicates that battery acid was stored
(and possibly leaked into the soil) in the vicinity of the POL Building. Therefore a limited
surface soil sampling investigation should occur to sample for heavy metals that may
have leached into the soil. At this time no background soil sampling is proposed
because it is believed there should not be significant concentrations of heavy metals at
this location. Therefore in the event significant concentrations of heavy metals are
present in these surface soil samples additional testing will have to be performed to
determine the nature and extent as well as the background heavy metal concentrations.
The proposed costs for this Phase I EA sampling effort are as follows:
Activity Cost
Drilling $8,000
Oversight and Reporting $7,000
Analytical $3,000
Total $18,000
Upon completion of this field work the City of Kalispell will have performed a Phase II of
sufficient scope to reasonably determine whether any of the proposed activities reported
in the Phase I EA have had a material impact at the Armory site. In the event this field
effort determines the presence of regulated compounds in soil or groundwater at the
site, this sampling protocol and installation of monitoring wells will facilitate any
additional determination into the nature and extent of contamination.
Please contact me after you have reviewed this proposal to discuss the schedule to
perform this work.
Sincerely,
MORRISON MAIERLE, INC.
