Commission Memorandum
REPORT TO: Honorable Mayor and City Commission
FROM: Rick Hixson, City Engineer SUBJECT: Environmental Consulting Services East Gallatin Landfill Professional Services Agreement
AGENDA ITEM TYPE: Consent MEETING DATE: December 18, 2017
RECOMMENDATION: Authorize the City Manager to execute a Professional Services Agreement (PSA) with Water and Environmental Technologies, Inc., to provide environmental consulting services pertinent to the East Gallatin Landfill. BACKGROUND: The East Gallatin Landfill, located north of Griffin Drive in Bozeman, is an inactive, approximately 30-acre municipal landfill which operated from 1962 to 1970. The city now leases the site to Montana Department of Fish, Wildlife & Parks as part of the East Gallatin Recreation Area (commonly known as Glen Lake).
A 1983 CERCLA preliminary assessment by Montana Department of Health and Environmental Services(MDHES) (now the Montana Department of Environmental Quality (DEQ)) summarized the contamination potential from landfill leachate and indicated a site investigation was warranted. EPA consultants sampled soils, groundwater from nearby domestic wells, and sediments and surface water from Glen Lake and the East Gallatin River. None of the
contaminant levels found were considered significant and based on investigation and health risk assessment results, EPA declared the facility "No Further Action" under CERCLA. The facility is currently listed as a low priority facility on DEQ's CECRA priority list. The area near the old landfill is now seeing increasing development pressure. In recent years,
Gallatin Park Subdivision and Subdivision 154A have been platted and are in the process of developing. In addition to Glen Lake, the East Gallatin River, a cold water fishery, flows along the east boundary of the landfill. The recreation area is heavily used in summers for swimming, boating and other water activities.

The purpose of this PSA is to provide the necessary professional environmental consulting
