Abandoned and inactive mine and mill sites document a heritage rich in mineral extraction in Montana, Idaho, and surrounding states. These sites also present a variety of challenges, including physical and environmental hazardous mine openings, dangerous highwalls, and dilapidated structures. Environmental hazards include heavy metal impacts to soil, surface water, sediment, and groundwater.

Olympus’ team of engineers, geologists, and field service staff is ideally suited to undertake mine reclamation projects. We provide assessment services for the characterization of mine waste sites and use the characterization data in the preparation of feasibility studies and remedial options for our clients in Montana, Idaho, North Dakota, South Dakota, Washington, Oregon, and surrounding states. Our engineers and geologists use the selected remedial option to design the reclamation project, with construction completed by our field services staff or qualified subcontractors.

"We initially met Olympus Technical Services when they were working as a subcontractor on an EPA TBA. We needed some work done quickly (it was under our bid threshold) and Preston Chase made it clear that Olympus could and would perform that work immediately and at an advantaged rate.

We hired them and the work was done quickly and professionally. Later, Olympus won a major demolition bid with FCEDA. The bid was fair and the work was started right on time and finished in advance of our deadline. It was a difficult job with several unknowns that caused delays, change orders, and equipment breakdowns. Throughout, Preston and his team were professional, flexible, and made sound recommendations. They were great partners on a difficult project. In spite of these setbacks, never once were there complaints, excuses, or delays that weren’t overcome. Because of this project, we have highly recommended Olympus Technical Services to many of our partners.

FCEDA has gone on to have additional engagements with Preston and Olympus resulting in the same solid partnership. They are always willing to engage, provide feedback, complete the job on time and on budget (or under in some cases). It has been a pleasure to work with such a professional and talented group!"

"The company motto for Olympus Technical Services, Inc. should be “we are here to do whatever it takes to get the job done.” The team of professional personnel at Olympus are each highly qualified, responsive, and innovative. Their problem-solving methods and can-do attitudes create results.

Consistently, Olympus meets all three aspects of the Project Management triangle: quality, schedule,and budget.

Olympus offers so much more than operating yellow iron. For a complex, web-based, GIS project in East Helena, Olympus responded to numerous revisions with accuracy and offered creative resolutions to complex challenges for the data presentation.

At remote project locations around Montana, Olympus comes prepared with necessary resources and anticipates needs, resulting in efficient execution of the scope of work with minimal down time.

The heavy equipment operators at Olympus are skilled, safe, and meticulous. Olympus’ commitment to safety and quality is unparalleled by most companies.

At a large Superfund site in Billings involving many stakeholders and numerous other subcontractors, Olympus flawlessly managed unexpected complications in the field and responded with flexibility to schedule changes as a result of others. Olympus excavated and managed the ex-situ treatment of ________ cubic yards of soil and constructed a soil vapor extraction system, including a treatment shed with doors customized by one of their team. Once the system was up and running, Olympus provided technical expertise by conducting monthly maintenance checks and performance monitoring reliably and accurately.

Olympus also supported periodic groundwater monitoring; again, anticipating field needs and providing experienced personnel with the appropriate quantity and types of equipment and supplies.

Olympus consistently provides quality technical expertise and work products satisfying client needs while meeting schedules and within budgets. They are flexible and creative to meet project needs."
