Box 580 Fort Collins, Colorado 80522 Subject: Well Abandonment & Reporting – Change Order Estimate City of Fort Collins - Fleet Services Center 835 Wood Street Fort Collins, Colorado OPS Event ID: 13349 City of Fort Collins PO#9192222 Dear Ms. Henggeler: This correspondence presents CGRS, Inc.’s (CGRS’) scope of work and cost estimate for decommissioning all site monitoring wells. The event is anticipated to achieve Tier-1 Closure following the fourth quarter 2020 monitoring event, and the wells will be decommissioned by the end of the second quarter 2021. The scope of work detailed below will be performed as a change order to the current PO# 9192222, which appears to have enough budget remaining to cover the costs of these activities. The requested change order would include verbiage for the scope of work below, and an expiration extension to June 30, 2021 in order to complete the additional work. Scope of Work The proposed scope of work will include the following:  Mobilize a technician to plug and abandon four monitoring wells (MW-5, MW-7, MW-8 and AS-1) per Colorado State Engineer standards. The wells are circled on the attached Site Map.  Saw-cut the concrete around all four manways, add dowels, and patch concrete over each core to prevent concrete settling.  Prepare and submit Well Abandonment Reports to the Colorado Department of Natural Resources – Division of Water Resources (DWR) as required for all permitted wells.  Prepare and submit a Site Decommissioning Report (SDR) to OPS. Limitations The work will be performed based upon the information provided to CGRS and on our observations made at the time of field activities. Given the inherent limitations of environmental assessment work, CGRS does not guarantee that latent or undiscovered conditions will not become evident in the future. No other warranties, representations, or certifications are made. Petroleum impacts in the subsurface are regulated by Colorado OPS and it is at their sole discretion to regulate, enforce, and interpret petroleum storage tank regulations. CGRS provides consultation services concerning state DocuSign Envelope ID: 472FEA15-CCE9-44AB-9911-5EF6313AD010 and federal regulations and interaction with government agencies but makes no warranties, expressed or implied, concerning decisions and outcomes determined by State or Federal regulatory agencies. Project Compensation Based upon the scope of work described in this proposal, the budget remaining for PO# 9192222 appears to be sufficient for the estimated costs to complete the site decommissioning and reporting. All costs for this proposal were completed according to the Colorado OPS Reasonable Cost Guidelines (RCGs), which are specific rates set by the State. The requested change order would include verbiage for the scope of work detailed above, and an expiration extension to June 30, 2021 in order to complete the additional work. If you have any questions regarding this proposal or details regarding the site or project, please contact Brannan Davis at (970) 218-4072. Sincerely, CGRS, Inc. Tarah Winterfeld, G.I.T.
