The field investigation and reporting will include: • A site reconnaissance • Surface and subsurface soil investigation (at eight locations) • Description of sampling procedures and analytical results • A report-of-findings Report Preparation Analytical results of the samples will be reviewed and summarized in a report. Three copies of the report will be provided for your review and use. The report will include the following information: • Date(s) that the field activities were conducted; • Description of current site conditions and field activities; • Description of site-specific soil conditions; • Summary of sample type, location, media, and rationale; • Summary of decontamination procedures and handling of investigative derived waste; • Summary of quality assurance/quality control procedures; • Site map(s) showing sample locations; • Tabular summary of rele�ant data compared to applicable standards. Fee - $5,335.00 PHASE 200, TASK 202 — Drilling Services Utilizing the services of a certified subsurtace driller, OLSSON will collect soil samples from eight (8) locations within the Tank Farm limits. Two (2) samples will be collected per location for soils analysis (one surface and one subsurFace). The investigation is intended to confirm the presence of contamination associated with the historical use of the assessment property. Drilling services for this investigation include: • A GEOPROBE� 6620 Track Unit will be used to collect soil samples to groundwater level or probe refusal, whichever occurs first. Maximum drilling depth for each location is 20 feet below ground surface. Decontamination of drilli�g equipment will be completed between each boring location. • Soil samples will be collected for the purposes of logging and laboratory analysis. Continuous samples will be collected using Macro-Core� 2"-Soil Sampling Liners in five-foot increments. Onsite analysis for volatile organic compounds will be measured by a photo ionization detector (PID). PID analysis will be performed to identify the five-foot subsurFace sample with the highest volatile organic compound index, and the sample with the highest index will be sent to the laboratory for analysis. • After completion of soil sampling activities, boring location will be backfilled with bentonite. Fee - $2,500.00 PHASE 200, TASK 203 — Laboratory Analysis Soil samples will be packed on ice, stored in coolers, and sent to a certified laboratory for analysis. Selection of analytical parameters was determined by historical use of the assessment property.

Hennen, Olsson Associa� Re: Environmental Testing (Horizons) Attached, please find a detailed proposal in the amount of $10,685.00 for the field testing and reporting of the abandoned tank farm located in the Horizons development area. This area (now designated as Horizons) once hosted an active oil field that included wells and a limited amount of on-site oil storage. Oil pumped from the wells was transferred via above- ground piping into a temporary storage facility referred to as `the tank farm'. The existence of the tank farm was noted in the environmental due diligence studies generated for the property. Our proposed testing and reporting is the next step in the environmental process and will seek to confirm and identify any remaining ground contaminants. The proposed scope of work includes subsurface investigation (eight borings), laboratory analysis, testing of remaining piping for contaminants, and a published report in accordance with acceptable regulatory standards. In the event that contaminants are located at the site, Olsson will immediately advise the city on the proper course of action. We will be available at the Board meeting to answer any questions or we may be contacted in advance at 816.442.6002.
