Client Challenge
A former refinery site had been dormant for decades when the owner, a global oil company, sought to prepare the property for sale. The property had widespread elevated concentrations of lead in surface soil resulting from historic oil-treatment processes. The potential presence of the Texas horned lizard, a threatened species, posed a significant risk to escalated remediation costs.
Client Challenge
While refinery operations have been idled at this 1,700-acre petroleum processing facility, a facility-wide environmental remediation/compliance program has continued under the US EPA Region 2 RCRA program. The facility requires a wide range of environmental activities to maintain compliance and to protect the refinery infrastructure for future revitalization.
Client Challenge
This active refining facility, located on the bluffs of the Mississippi River, is comprised of thousands of acres and integrated facilities used to produce, store, and transport gasoline, diesel, jet fuel, aviation fuel, lubricating oils, and waxes. The environmental impacts from decades of operation are addressed with an understanding of compliance needs as well as an insight into how to best minimize costs and avoid disruption of round-the-clock operations.
Client Challenge
A national power company is progressing in its long-term strategy for the decommissioning, remediation, and restoration of a former coal-fired power plant that served thousands of customers in the Washington, DC metro area. Petroleum impacts were noted to soil and groundwater following the closure of two 25,000-gallon underground heating-oil storage tanks centrally located within the power plant complex.
Client Challenge
A multinational gas and electric company with significant presence in the Northeast is responsible for the environmental management of former manufactured gas plant (MGP) sites inherited through business transactions. A portfolio of 21 MGP sites across upstate New York is managed under a long-term remediation program for greater cost effectiveness and quality assurance. Long-term operation, maintenance, and monitoring (OM&M) of engineering and institutional controls is required for regulatory compliance.
Client Challenge
The construction of new natural gas pipelines is an important component of this energy company’s strategy to improve service for its customers across the southeastern US. A planned interstate natural gas pipeline would stretch 550 linear miles and intersect thousands of land parcels. Support properties along the route would be used to stage and store pipe sections, equipment, vehicles, and construction materials.
Client Challenge
Over time, it can be challenging to maintain accurate and current records of every single company asset. When the 2014 West Virginia Storage Tank Act was promulgated, new requirements were placed for aboveground storage tank (AST) registration, spill prevention plans, and certified inspections, with a tight compliance timeframe. This spurred a power company to rapidly evaluate and document over 500 ASTs located at natural gas wellhead gathering facilities, compressor stations, and fractionation plants across the statewide natural gas pipeline system.
Client Challenge
An aerospace leader is managing the groundwater monitoring and sampling program within a section of a large, longstanding Superfund site, with remaining chlorinated solvent plumes. The facility owner, a leader in the aerospace industry, requested both professional hydrogeological consulting support and technical field services to achieve greater efficiencies in managing the monitoring program and optimizing remediation approaches.
Client Challenge
A global technology leader manages a multi-million-dollar remediation program across the US. These sites reflect diverse historic and current business operations with a wide range of regulatory governance, contaminant risks, and life-cycle maturity. The company has a formal program to ensure that operation, maintenance, and monitoring (OM&M) activities across this portfolio are carried out with adherence to a consistent strategy that combines continuous improvement and a focus on key performance indicators to evaluate ongoing program and project success.
Client Challenge
Elevated concentrations of chlorinated volatile organic compounds (CVOCs) in soil remained in a former perchloroethylene (PCE) and trichloroethylene (TCE) storage area at a former chemical manufacturing plant. Achieving regulatory closure for this area of concern (AOC) under the RCRA Corrective Action program, with no further action determination in this AOC, required a targeted soil cleanup. GES was retained to evaluate potential remedial solutions and to implement a technical and cost-effective alternative.
