Underground Storage Tank (UST) Services in Portland

Providing Free UST Consults Across the Portland Metro Area


Decommission methods include abandonment in place or complete removal. Abandonment in place is a strategy in which the tank is legally decommissioned without requiring complete removal. This is the most common method of closing a tank case. In the event of a complete removal, the tank is pulled out of the ground and hauled to the recycling center. This is usually called for when a structure is to be developed over the tank area or when a site is to be repurposed and causes up to seven tons of soil displacement. READ MORE...


If a UST release is discovered a working strategy will be developed to meet regulatory standards while managing financial impact to the responsible party. Environmental Works is made up of a team of experts highly skilled in the use of progressive investigation strategies for evaluating free product, groundwater, soil and soil gas.


Implementing the response to a release takes heavy machinery and the transport of soil by the ton. When it’s time to remediate, our Environmental Remediation Teams gets to work. The first step is to develop a site model that justifies the optimum Risk Based Corrective Action approach. From a cost perspective, the preferable approach is Monitored Natural Attenuation (MNA). If site conditions aren’t favorable to MNA we work with you to define priorities such as time, cost, cash flow and / or regulatory buy-in, for corrective action then identify and apply optimum methods & techniques.
