Private Brownfields
- Downtown Prineville Historic Building : Disentanglement & Redevelopment; Prineville, Oregon
Main street bunkhouse supplied much needed lodging for out of town Facebook data center construction workers.
EzraTerra recently completed a renovation of a downtown historic building; the building was disentangled from a regional gasoline groundwater plume. The lower floor is currently leased as retail space. The second floor was developed into an extended stay hotel for Facebook, and Apple data farm construction workers. The Main Street Bunkhouse house brings high wage earners to the downtown core of Prineville.
Brownfield Portfolio; Klamath Falls, Oregon
Patrick acquired four brownfield properties in Klamath Falls, Oregon. The properties consisted of one service station, two bulk plants and a former meat packing plant and had been investigated and managed by consultants for decades with no results. These properties were formerly owned by Unocal, Texaco, Chevron and Regal Stations. Soil and ground water were impacted at all the properties. Soil was excavated and treated with Evaporative Desorption. The sites were all closed in less than one year under Oregon Department of Environmental Quality Oversight. The projects were toured by the Oregon Environmental Quality Commissioners (Governor Appointees). The success of the projects led to a Chevron contract to perform soil treatment services.
P&A Wrecking Yard; Clackamas, Oregon
The P&A Auto Wrecking yard was a long standing blighted area ridden with crime. The property consisted of 12.5 acres of prime industrial land. There were 3,500 wrecked automobiles on the site and thousands of tons of other related debris. The site was located adjacent to a Superfund site and five other contaminated properties. The groundwater had commingled plumes from multiple sources.
The property was purchased under a Prospective Purchasers Agreement with the State of Oregon. The site was cleaned up and redeveloped into an industrial park. The development created 500 family wage jobs and was a catalyst for nearby developments.
Industrial Park was developed in place of the wrecking yard. Created hundreds of family wage jobs. Surrounding properties were subsequently redeveloped creating more jobs.
I-5 Truck Stop; Canyonville, Oregon
The Fat Harvey’s Truck Stop in Canyonville was contaminated with gasoline and diesel from leaking underground tanks and a historical bulk plant. Soil was excavated and treated onsite. A new $12 Million truck stop was developed in its place creating hundreds of jobs.
Remedial Excavation removing hydrocarbon contaminated soil for onsite treatment
The new $12 million Truck stop, which produce hundreds of jobs. Nearby properties were redeveloped following remediation.
Private Clients
Togiak Fisheries; Togiak, Alaska
Togiak Fisheries is located in a remote Alaska in northern Bristol Bay. The site is only accessed by sea or air; no roads. 
Togiak Fisheries historically used diesel and gasoline to fuel electrical generators for their freeze plant and camp operations. Gasoline was sold to the native skiff fishermen. The large storage tanks and associated piping resulted in large scale contamination of soil, groundwater, sediment and surface water. The beaches caught fire as petroleum seeped out of the sand. Patrick excavated and treated 70,000 tons of soil and sediment using the Permeation Bed Technology. Soil and sediment was primarily excavated from LNAPL areas. The sediment was excavated during the winter months when the ocean was frozen; sea ice was pushed away from the excavation areas to make way for excavation. Frozen sediment was placed in storage cells for later treatment in the summer months. All treated soil was sampled by third parties and met ADEC Method B cleanup standards. The facility was also licensed to accept off site soils under a ADEC Class C permit. The third party consultant estimated the cost for the project to be $12M; the project was completed with the Permeation Bed technology for $4M.
Confidential Client; Fullerton, California
Confidential Client company manufactured medical devices at the Fullerton Plant since the 1950s. Chlorinated hydrocarbons were detected in soil and groundwater during a RCRA closure investigation. The site was overseen by the California Department of Toxics Substance Control (DTSC). The consultant of record expected the remedy to take decades to complete. Soil was initially excavated and treated with Evaporative Desorption under a pilot testing program. South Coast Air Quality Management District issued air permits to operate. The DTSC authorized continued pilot testing operations until 100,000 tons were treated to non detectable concentrations in soil matrix and soil vapor. The site was closed before the Corrective Measure Study was completed by the consultants. The project was completed in less than one year.
100,000 tons of soil containing chlorinated solvents, at RCRA hazardous waste levels, were excavated and successfully treated to non-detectable levels in soil matrix and soil vapor.
The mapping capabilities assisted the consultant of record to close the site, identify the location of the groundwater source area and find an off-site source that was previously unknown. The project was completed using the Corrective Action Management Unit rules. The site is now under development for commercial and residential use. Hundreds of jobs were produced as a result of the timely remediation efforts.
Iron Partners Property; Vancouver, Washington
Ezraterra staff completed a site investigation and complete remediation of a historic landfill containing hazardous waste adjacent to the Columbia River using a unique technology centered approach.
1943 WWII Landfill containing Hazardous Waste
At the onset of WWII, the United States granted Kaiser Shipyards a contract to rapidly build liberty ships to support the war effort. The Kaiser Shipyard in Vancouver, Washington was located on the Columbia River. During manufacturing, debris and hazardous wastes were deposited in a landfill adjacent to the Columbia River.
The landfill was contaminated with hydrocarbons, PAHs, PCBs and lead; TCLP lead was detected up to 325 mg/l in the landfill soils. Soils were excavated, screened and chemically stabilized with the Apatite process.
The most contaminated soils (approximately 5,000 tons) were stabilized and transported as a non-hazardous waste to the Waste Management Hillsboro Landfill for disposal. Other soils were stabilized and were approved to leave on site. The historic debris was investigated by certified archaeologists. The site received an unconditional No Further Action letter from the Washington Department of Ecology.
Contaminated soil and debris
Debris from the WWI Landfill. These soils contained hazardous waste levels of lead. Hydrocarbons, PAHs and PCBs were also present in the soil. The debris had been burned prior to burial.
Rose City Plating; Portland, Oregon
The Rose City Plating property was contaminated with plating fluids, heavy metals, PAHs and hydrocarbons. The site was located in the middle of the historic Sellwood District of Portland. The property was a blight on the community, which prevented new businesses from entering the area. We complete building decontamination and demolition. We removed impacted soil and various underground tanks located during remedial activities. The site was returned to value and now hosts the County Library and high end town homes on the upper floors of the development.
Site demolition and remediation took place in the middle of a densely populate urban area.
The site went from a blighted hazard in the community to the center of the community.
Pro Bono
Senn’s Dairy Park Pro Bono; Portland, Oregon
Patrick donated site remediation and consulting services to bring a Portland Brownfield site to closure. All remediation costs were born by Patrick. The remediation and demolition waste was transported to the Waste Management Hillsboro Landfill. The site became a community Park and community garden.
Senn’s Dairy sat abandoned for decades in the middle of a neighborhood. Patrick completed site remediation at no charge to facilitate development of the City Park.
