RE: Proposal for Phase I Environmental Site Assessment
Turner/Griffin, L Street, Mill, Parks, Henderson, Turner II, Bridger View Parcels
Approximately 76 Acres in Bozeman, Montana
Dear Mr Diekmann:
Tetra Tech, Inc. (Tetra Tech) is pleased to submit this proposal to conduct a Phase I Environmental Site
Assessment (ESA) at the above referenced properties, seven parcels of land referred to herein as the
‘site’. This proposal outlines our understanding of the project, our proposed scope of work, the
estimated cost, and time schedule for completion of the project.
Tetra Tech 's approach to performing environmental assessments is consistent with generally accepted
and established practices (Standard E1527-05) as promulgated by the American Society of Testing and
Materials (ASTM) to comply with requirements of Standards and Practices for All Appropriate Inquiries;
Final Rule, as published by the U.S. Environmental Protection Agency on November 1, 2005. Phase I
involves review of the public record and reconnaissance of the site to identify evidence that hazardous
waste or hazardous materials may exist on the site. Phase II is comprised of collecting environmental
samples for laboratory analysis to confirm or deny the presence of soil and/or groundwater
contamination on the site. The details of any proposed Phase II work would be presented in our Phase I
report; such work would only be performed with your prior concurrence and approval.
The All Appropriate Inquires final rule requires that the user of the Phase I ESA provide specific
information on their knowledge of the site. Upon acceptance of this proposal, we will provide you with
a questionnaire to complete that will comply with requirements in the new ASTM standard.
Scope of Work
The following scope of work, and associated costs and schedule address Phase I ESA work only. For this
Phase I ESA Tetra Tech will:
1. Review the history of the site and surrounding area to identify possible previous activities that might
have introduced hazardous materials or petroleum products to the property using the following
resources: Sanborn Fire Insurance Maps, Polk City Directories, County appraisal records, ownership
records, a historical sequence of aerial photographs, and, interviews with past owners/occupants.

2. Review environmental information regarding the project site and surrounding area for ASTM
established search, using the following resources:
U.S. Environmental Protection Agency (EPA) databases, including National Priorities List (NPL);
Comprehensive Environmental Response, Compensation, and Liability Index System (CERCLIS)
and CERCLIS No Further Remedial Action Planned (NFRAP); Resource Conservation and Recovery
Act (RCRA) facilities under Corrective Action (CORRACTS); RCRA Non-CORRACTS for Treatment,
Storage, and Disposal (TSD) Facilities; RCRA Database for Generator and Transporter Facilities;
and, Emergency Response Notification System (ERNS).
Montana Department of Environmental Quality (MDEQ) databases including Comprehensive
Environmental Clean-up Responsibility Act (CECRA - State Superfund), Voluntary Cleanup and
Redevelopment Act (VCRA) Registry; Brownfields Registry; Water Quality Act (WQA) Database;
Solid Waste Registration (Landfills), Underground Storage Tanks (UST) and Leaking Underground
Storage Tanks (LUST).
Interview appropriate local, state, and/or federal officials to determine if there is knowledge of
hazardous materials or other contaminants on the site or within the immediate vicinity.
3. Interview the site owners for information on the history of the property and current conditions.
4. Obtain physical data to evaluate contaminant movement at the site using the following criteria:
hydrogeologic setting, flood plain information, surface water, nearby well locations, subsurface
geological characterization, and soil survey characterization.
5. Inspect the site for visual evidence of contamination. These include subsidence, stressed
vegetation, surface anomalies, unusual soil discoloration, and evidence of chemical usage, spills, and
underground storage tanks. The inspection will include an evaluation of surface drainage patterns
on or immediately adjacent to the site to note possible areas of concern, transformers, and on-site
chemical use. Photographs of the site will be taken to document pertinent features, such as those
listed above.
6. After completing our review of the public record and site reconnaissance, Tetra Tech will complete a
written report documenting our evaluation. The Phase I report would reflect our evaluation of the
site and will include a description of the evaluation methods, discussion of results, conclusions, and
recommendations. Three copies of the project report will be provided and an electronic version on
CD.
Estimated Cost and Schedule for Completion
Tetra Tech will complete the Phase I ESA, according to the scope of work presented above, for a lump
sum fee of $10,000. If additional work is required, such that this estimate would be exceeded, we would
contact you to discuss our recommendations and receive your authorization before proceeding.

We anticipate submitting the written Phase I report eight weeks of receipt of a signed contract. Please
note that our ability to complete the review of available public information within the anticipated time
frame is dependent upon the availability of certain resources, including records and government
personnel. If we have difficulties in this regard, we will inform you at the earliest possible time. We will
obtain your concurrence on extending the evaluation time frame, or terminate that aspect of our
evaluation and report the findings without the benefit of that information.
Limitations
It should be understood that the findings and conclusions of the Phase I ESA will not be scientific
certainties, but rather opinions based on our professional judgment concerning the significance of the
data gathered during the course of the site assessment. Tetra Tech will not be able to represent that
the site contains no hazardous waste or materials, petroleum products, or other latent conditions
beyond that detected or observed by Tetra Tech personnel during the site assessment.
Tetra Tech would sincerely appreciate the opportunity to work with you on this project. If you have any
questions regarding our proposed scope of work, please contact us at 406-443-5210.
Sincerely,
Daphne Digrindakis
ESA Program Manager
