WHEREAS, the City Council by Resolution No. D-5646 autho- rized execution of an Agreement with Hall Engineering Associ- ates to conduct research, analysis, design, and reporting for the City of Yakima Downtown Transfer Center; and WHEREAS, the City wishes Hall Engineering Associates to perform additional work not included in the original Agree- ment; and WHEREAS, the City Council deems it to be in the best interest of the City that an amendment to the aforementioned contract be executed, now, therefore, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF YAKIMA: The City Manager and the City Clerk are hereby authorized and directed to execute "Amendment No. 6 to the Contract" with Hall Engineering Associates, for the purpose mentioned above, a copy of which Agreement is attached hereto and by reference made part hereof. ADOPTED BY THE CITY COUNCIL this 25th day of June 1991. ATTEST: jLZ Ci it.trAue.A.,1D y Clerk (res/profserv.1) &e4 Mayor 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. 1 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. 2 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. 3 Task Order 5, pg. 4 Engineer's fee for Part C will be a fixed fee of $7,000.00.
