USPS Awarded Alisto a 5-Year IQ Contract for Environmental Support Services for the Second Time

The United States Postal Service (USPS) Denver Facilities Services Office recently awarded Alisto an indefinite quantity contract to provide a broad range of environmental services to support real estate functions in 17 western and mid-western states, including Alaska. This new IQ contract effective June 2003 is for a base period of two years with an option for 3 one-year extensions for a contract value of $5.0 million. In 1998, the USPS awarded Alisto a similar IQ contract for environmental services, which was extended to the full 5-year term until May 2003.

Environmental Services at Four Upcountry Wastewater Management Facilities of EBMUD

Alisto, as subcontractor to RMC Engineers, is providing environmental services to comply with the waste discharge permits issued by the California Regional Water Quality Control Board at four upcountry wastewater management facilities of the East Bay Municipal Utility District (EBMUD) in Calaveras and Amador Counties. The scope of work includes preparation of work plans for groundwater monitoring of surface impoundments or treatment ponds and investigation of potential pond seepage. After regulatory approval of the work plans, Alisto will install the monitoring network and implement the groundwater monitoring program.

ExxonMobil Signed a 5-Year Continuing Services Agreement with Alisto

In September 2001, Alisto entered into a 5-year continuing services agreement (CSA) with ExxonMobil to provide environmental services throughout the western states. The agreement covers a broad range of services including site investigation and remediation, regulatory compliance monitoring and auditing, and environmental engineering and construction oversight. The CSA is available to all business units of ExxonMobil from exploration and production to refining and retail marketing.

Pollution Prevention and Waste Minimization Study at Hot Zinc Galvanizing Plant in Bulgaria Completed

Under an Ecolinks grant from the US Agency for International Development, Alisto partnered with two Bulgarian companies to conduct a pollution prevention and waste minimization study at one of the largest hot zinc galvanizing plant in Bulgaria. The 8-month long study involved evaluating the existing process and determining alternative to reduce discharge of pollutants, minimize waste generation and demand for raw materials and conserve energy and water resources. After review of available technologies and existing process, Alisto recommended various no or low cost technologies and modifications to minimize or eliminate waste generation and increase material recovery. It was estimated that implementation of the recommended modifications would result in at least 75 percent reduction in water use and wastewater discharge, decrease in energy demand and recovery of almost 90 tons of zinc. The waste reduction would also eliminate the disposal of hazardous waste to landfills and discharge to the municipal wastewater treatment system.

Contract for Monitoring Services at Two Landfills Extended for Three Years

Based on our performance and service in the past three years, both the County of Merced and the Monterey Regional Waste Management District extended Alisto's contract for landfill compliance monitoring for an additional three years. The scope of our services includes quarterly or semi-annual groundwater, leachate and landfill gas monitoring and sampling and preparation of reports for submittal to the regulatory agencies. The report includes statistical analysis of monitoring parameters or constituents of concern to determine potential release from the landfill or non-compliance with regulatory requirements.

Pilot Study of Chromium Remediation Technologies

Alisto completed a research study of alternative methods for remediation and treatment of chromium-contaminated groundwater. The two-year long study identified natural attenuation and in-situ process as the most viable technologies provided that the appropriate geochemical and physical characteristics are present in the subsurface environment.

As a continuation of the initial study, Alisto was then authorized by a major public utility to conduct additional pilot study to assess the applicability of in-situ process for remediation of hexavalent chromium in groundwater at a specific site. The study included both bench and field testing of in-situ Cr(VI) reduction using reactive treatment zone and pilot testing of ion exchange for ex-situ treatment. The results of the study were to be used in the development of a corrective action plan to address the chromium contamination in groundwater at two sites.

 

Final Environmental Assessment for Relocation of USPS WNET-Hub

The expedited mail service (express mail) of the United States Postal Service (USPS) within the western states is managed by Western Network Operation (WNET-Hub), which previously operated out of the Oakland International Airport .  Because of facility limitations, the USPS decided to relocate the WNET-Hub operation to a different airport.  As required under NEPA and by the Federal Aviation Administration (FAA), the USPS had to prepare an environmental assessment (EA) to identify and evaluate potential impact of the WNET operation at a new location.  The two alternative sites considered were the Reno/Tahoe International Airport and the Mather County Airport near Sacramento , California . The primary environmental impact associated with the WNET operation was the increase in noise level above 65 dB in residential areas during nighttime flights. A noise computer modeling was performed for various airplane lift scenarios to determine the increase in noise contour level within sensitive areas near the airports. Alisto completed the final EA in August 2000 including the determination of Finding of No Significant Impact (FONSI).

Alisto's Project Subject of Julia Roberts' Movie, "Erin Brokovich"

Julia Roberts stars in "Erin Brokovich", a movie about chromium contamination of the groundwater supply in the small town of Hinkley , California . Alisto has served as the environmental consultant for this project since 1993 providing a broad scope of services for the ongoing remediation of the groundwater, including operation and maintenance of the groundwater extraction and land treatment system, and compliance monitoring.
