TEAM has provided multi-faceted environmental support to Mammoth Mountain Ski Area (MMSA) on numerous properties and clean-up sites. Environmental consulting services to MMSA have included underground fuel storage tank (UST) site investigations and clean-up, air quality permitting, soil sampling, hazardous waste disposal, wastewater treatment evaluation, Phase I and Phase II Environmental Site Assessments, subsurface investigations, groundwater supply assessments, and National Environmental Policy Act (NEPA) document preparation in conjunction with the Inyo National Forest.

In 1999, when a 7,000-gallon fuel spill occurred at MMSA’s industrial maintenance facility, TEAM hydrogeologists, geologists, and environmental scientists responded immediately with steps to contain, investigate, and remediate the fuel release. The rapid response included start-up of a large-scale vapor extraction system, and the design and implementation of a bio-enhanced groundwater remediation system which TEAM operated for over 10 years.

These efforts proved successful at containing and recovering the fuel spill in a manner that protected the groundwater resources of the Town of Mammoth Lakes. TEAM worked with multiple regulatory agencies and provided incident reenactment and litigation support that resulted in significant savings to MMSA. Clean-up and reporting requirements by the California Regional Water Quality Control Board were successfully completed, obtaining site closure for MMSA in 2011 in a manner that was protective of crucial groundwater resources in the Mammoth Lakes area.
