AMENDMENT NO. 6
TASK ORDER NO. 5 Contamination & Asbestos Assessment
Of the contract for the provision of professional services between City of Yakima,
hereinafter called "City", and Hall Engineering Associates, hereinafter called
"Engineer" dated October 18, 1989, and
WHEREAS City wishes to investigate the potential for contamination of the soils
resulting from significant releases of hazardous substances and the potential presence
of asbestos in the buildings at the proposed transit center located on the east side of
South Fourth Street between East Chestnut and Walnut Streets and the vacant lot on
the northwest corner of Walnut Street and Naches Avenue, hereinafter called "the
site".
Then the parties agree as follows:
Scope of Services
PART A: Phase 1 Environmental Site Assessment
Scope of Work: The scope of work for a Phase 1 Environmental Site Assessment is
designed to assess the potential for site contamination based on present and past site
usage, by reviewing available data. No sampling will be conducted for this phase.
The scope of work for the Phase 1 study will include the following:
(1.) Review the history of site usage, available property records, historical property
maps, city directories, and other available information.
(2.) Review commercially available aerial photographs, which may provide visual
information on the historic development and usage of the site.
(3.) Review available subsurface studies previously performed at the site to
evaluate the subsurface conditions encountered.
(4.) Review reasonably obtainable records from federal, state, and local agencies
to evaluate compliance with regulations concerning the generation, storage,
treatment and disposal of hazardous materials or wastes at the site. Records
of spills and other disposal activities or permit violations which could result in
site contamination will also be researched.

Task Order 5, pg. 2
(5.)
(6.)
Conduct a site visit to observe the property and adjacent land for current use
and indications of potential soil and groundwater contamination. This may
include soil staining, distressed vegetation, evidence of underground storage
tanks, trash and debris, and use of hazardous materials or petroleum products.
Prepare a final report which presents the data and findings of the assessment
and conclusions concerning the potential for subsurface contamination as the
result of previous or current site activities. Evaluation will also be presented
regarding the extent of sampling required and recommendations for further
work, if necessary, at the site. Copies of relevant documents obtained during
the study will be included in the report.
Fee: Engineer's fee for Part A will be a fixed fee of $8,000.00.
Schedule: Engineer will begin work promptly upon written notification to proceed, and
will provide a written report to you in approximately six weeks from receipt of
authorization to proceed. Receipt of written responses from governmental agencies
and aerial photographs sometimes are not received within this time frame, but will be
furnished when available.
PART B: Phase II Environmental Site Assessment
Scope of Work: The scope of work for a Phase I1 Environmental Site Assessment
is designed to assess the potential for site contamination based on present and past
site usage. Based on the information obtained during the Phase I assessment,
appropriate locations for subsurface investigation will be selected.
The scope of work for the Phase II environmental assessment will include the
following:
Subsurface Investigation - Up to two exploration borings will be drilled at each
of the parcels selected for investigations. The exact locations of the borings
will be determined by our field engineer during the field investigation. Based
on expected field conditions, the borings will be extended to a depth of 15 to
25 feet. Engineer's representative will maintain a lithologic log using the
Unified Soil Classification System (ASTM D2487) during drilling activities.
Drilling equipment will be decontaminated prior to beginning the drilling
operation and between each hole. City will provide water for decontamination
of drilling equipment at no cost to Engineer. The drilling is expected to be
somewhat difficult, and it is anticipated that cable tool or rotary drilling
methods will be required.

Task Order 5, pg. 3
(2.)
Laboratory Analysis - In order to assess subsurface conditions at the site, soil
and groundwater samples will be collected from each boring for laboratory
analysis. Selected samples will be tested for total petroleum hydrocarbons
(EPA Method 418.1), volatile organic constituents (Methods 8020, soil;
Method 602, water), and solvents (Method 8010).
(3.) A report will be prepared summarizing the data obtained and presenting
observations and conclusions relating to the apparent subsurface conditions as
the result of previous or current site activities. The report will contain the
analytical laboratory results and an opinion with regard to the presence of
hazardous materials or petroleum products in the subsurface soil or
groundwater at the sites.
Fee: Engineer will provide Part B scope of services outlined for a lump sum fee of
$7,500.00 per parcel determined in Phase I Enviromental Site Assessment to require
Phase II investigation.
Schedule: As previously noted, completion of the Phase I site assessment is expected
to take approximately four weeks after receipt of notice to proceed. During the Phase
I investigation, the scope of work for the Phase II study can be refined, if necessary.
After the work scope has been finalized, we can begin mobilizing and drilling activities
upon contract rig availability.
The findings and conclusions from Engineer's Phase I and II Site Assessments will not
be scientific certainties, but rather opinion based on or professional judgement
concerning the significance of the data gathered during the course of the site
assessment and its indications of abnormal site activities relative to similar sites and
usage. We will not be able to represent that sites contain no hazardous materials,
petroleum products or other latent conditions beyond that detected or observed during
the site assessments.
PART C: Asbestos Survey
Engineer will survey existing buildings on the site for asbestos containing materials to
identify and sample suspect building materials for laboratory analysis. Materials
sampled will include but not be limited to: Floor coverings, wall materials, ceiling tiles,
textured ceiling materials, exterior stucco materials, roofing, piping insulation, and
equipment isolation pads.
