Memo - The BMRI File
Selection of Third Party Contractor & Lab
page 2
Dr. Harry Posey of our DMG staff and Andre' J. Douchane, representig BMRI,
participated in the approximately 1 and 1/2 hour interviews. Both ~f the
nominees, RCG/Hagler, Bailly, Inc. and Waste, Water & Land, Inc., 5 bmitted
written proposals following their interviews. My final decision was based
upon a consideration of all written submittals, the oral interview experience,
and discussion with Dr. Posey.
Selection of an Analytical Laboratory
The fee schedules of Analytical Technologies, Inc. and Core Laborato tes, Inc.
are similar, so cost did not appear to be a discriminate factor. Bo h
laboratories are EPA certified, and have extensive analytical experi nce in
mining related situations. Each laboratory is capable of performingthe
procedures specified within the TR-006 analytical protocols, however
Analytical Technologies has never performed weak acid dissociable (W A.D.)
cyanide analyses. ATI's routine cyanide analytical services include "Free",
"Total" and "Cyanide Amenable to Chlorination". They do possess the equipment
necessary for W.A.D. cyanide analysis and are receptive to providing the
services.
At my request, Dr. Posey, an experienced geochemist, conducted in de th
telephone interviews with both laboratories. Harry has also been ch efly
responsible for the geochemical opinions rendered by DMG throughout he past
six months analysis of the BMRI violation abatement. It is Dr. Pose 's
recommendation that the Division designate Core Laboratories, Inc. a the
analytical laboratory to perform the analytical determinations for t e "third
party monitoring" at BMRI's San Luis mine. Harry cites the start up time
required for ATI to perfect W.A.D. techniques, the extensive experie ce of
Core Laboratories in W.A.D. analysis, and Core's demonstrated willin Hess and
ability to perfect their techniques to achieve the required QA/QC pe formance
in analyzing BMRI samples, as justification for his recommendation. I concur
with Dr. Posey's recommendation and designate Core Laboratories as the
analytical laboratory for the third party monitoring sample analysis.
Selection of the "Third Party Sampler"
Ann S. Maest, PhD., participated in the interview and prepared the written
proposal for RCG/Hagler, Bailly, Inc. Dr. Maest is an experienced ge chemist,
with experience in environmental impact related geochemical project a pects.
Dr. Maest is also qualified and experienced in water quality, water r source
evaluation, and sedimentology. She has significant first hand experi nce in
water quality sampling and geochemical analytical procedures. Dr. Ma st
proposes to conduct the water quality sampling and report preparation
personally. Dr. Maest proposes to complete a pre-sampling evaluation of the
approved sampling and analytical protocols established for BMRI throw h
TR-006. She proposes to complete the required sampling oversite, sam le
preparation and delivery to the laboratory, and to review the analyti al
