Following the completion of the Utah Transit Authority's north-south running light-rail corridor (TRAX) in the Salt Lake Valley, land developers seized the opportunity to redevelop neighborhoods around commuter and light-rail stations. During this time, IHI worked closely with a number of these companies to redevelop properties around the Murray North Station from a former industrial area to a multi-use residential and commercial transit-oriented development. Before redevelopment of the area could begin, several environmental issues needed to be addressed. Historical industrial uses around the Murray North Station included a steel fabrication facility, a former lead smelter that operated between 1874 and 1902, and a mining equipment salvage and refurbishing company.
Impacted Properties: Environmental impacts associated with these industrial operations included the following:
- Metals-impacted surface and near-surface soils
- Low-level radioactive ores from historical tailings in the area and from ores falling off mining equipment
- Polychlorinated biphenyl-impacted surface soils from old transformers stored on the mining equipment property
- Metals-impacted sediments in the north-adjoining Big Cottonwood Creek
- Petroleum-impacted soils and groundwater caused by leaking equipment and underground storage tank systems
IHI conducted multiple investigations on each property to identify and delineate the extent and degree of the environmental impacts. IHI collected samples of surface and subsurface soils;
surface water and groundwater; and sediments from Big Cottonwood Creek. As a precautionary measure during remediation construction activities, IHI also performed community air monitoring for impacted fugitive dust. Testing included direct-reading field measurements using an X-ray Fluorescence Analyzer (XRF) for metals-impacted soils, a photoionization detector for petroleum hydrocarbon-impacted soils, and a Geiger counter for the evaluation of radiation levels. IHI also used several types of analyses for the samples collected during these environmental investigations. Laboratory analyses included speciation of the lead in soils to characterize the contaminant and streamline remediation efforts; the use of local analytical laboratories for the metals and hydrocarbons; and utilization of a specialized out-of-state analytical laboratory for the low-level radioactive waste analyses.
All three of the properties around the Murray North Station were remediated under Utah's Voluntary Cleanup Program (VCP), which required the preparation of specific plans related to remediation activities.
These planning requirements included the following:
- Sampling and Analysis Plans
- Quality Assurance Project Plans
- Site Remediation Work Plans
- Post-Remediation Site Management Plans
A portion of the former steel fabrication property was also regulated by Utah's Leaking Underground Storage Tank Program, which was specifically carved out of the VCP project. All three properties have received Certificates of Completion, which document successful remediation of the properties to the specifications outlined in the work plans for the intended future land uses.
Redevelopment activities were initiated on one of the three properties, while the other two parcels were delayed because of the economic downturn of 2008. Developers are currently in the process of initiating construction activities on the remaining two parcels.
As a key stakeholder in the redevelopment of this area, Murray City has provided some financial assistance to the remediation efforts and has worked closely with the developers to help facilitate successful projects.
