Wayne Perry, Inc. has served as one of Shell Oil Products US’s primary consultants for environmental project management and consulting services at over 600 locations throughout the Western U.S. Wayne Perry, Inc. is currently the primary environmental consultant on 220 Shell stations in California and Nevada. In this capacity, Wayne Perry, Inc. manages all aspects of each project, including budgeting, subcontractor qualification and selection, environmental assessment services (Phase I and II environmental site investigations) as well as the design, construction installation, and operation/maintenance of soil and groundwater treatment systems.

We designed, constructed, installed, operated, and maintained remedial systems with all in-house personnel. Types of these systems include soil vapor extraction, dual phase extraction, and multi-phase extraction systems that use a variety of contaminant vapor treatment technology, such as catalytic and thermal oxidizers, internal combustion engines, and activated carbon.

Groundwater remediation installations have included air sparging, carbon adsorption, air stripping, oxygenation, bioremediation, and ozone/hydrogen peroxide systems. We have also included in-site chemical oxidation at numerous sites, using a variety of oxidizing agents (e.g., potassium permanganate, hydrogen peroxide, Fenton’s Reagent, etc.) to effectively reduce a variety of soil and groundwater contaminants to concentrations that are acceptable for regulatory approved closure. We are currently operating remediation systems at approximately 100 sites.

The Wayne Perry, Inc.’s feasibility/treatability analysis generally includes consideration of green remedial methods (like monitored natural attenuation) that significantly reduce factors such as site visit requirements or utility usage. These remedial methods reduce the overall environmental impact created by conventional remedial activities.

As part of this program, Wayne Perry, Inc. is responsible for profiling, transporting, and disposing of both hazardous and non-hazardous waste. A Wayne Perry, Inc. waste coordinator oversees the disposition of over 235 separate source events per year. Types of waste vary from a single drum of groundwater to 3,000 tons of impacted soil. Disposal options are evaluated with a special emphasis placed on recycling. Where the waste is destroyed, the residual soil and water is reused.

We also provide environmental oversight for construction at Shell’s fueling facilities. Wayne Perry, Inc. has monitored air quality to ensure compliance with South Coast AQMD Rule 1166. During construction projects, soil samples are obtained most commonly from below former UST and piping locations at the discretion and direction of the governing agency.

Soil samples are also routinely obtained from soil stockpiles for disposal profiling. All analyses are conducted by an independent California-certified analytic laboratory. Construction activities and analytical results are documented in a report reviewed, signed, and stamped by a California professional engineer or geologist. These reports are submitted to the appropriate agency on behalf of Shell.
