Featured Site-Specific Profile *Update*

The environmental footprint of cleanup activities at the Aerojet-General NPL site in Rancho Cordova, California, has been reduced through a strategy involving generation of electricity from onsite renewable energy sources, reclaiming treated water for non-potable uses, and preserving ecosystem services across the 5,900-acre site. About 30 percent of the grid electricity used to operate multiple groundwater extraction and treatment systems is now offset by an operating solar farm, and about 700,000 gallons of the water treated each day are used for ongoing site activities. Land use plans for portions of the site include a municipal open space and park near the lower American River, a state- and nationally-designated recreational river with high biodiversity.

Greener Cleanup Bulletins
Travis Air Force Base

A subgrade biogeochemical reactor at Travis Air Force Base in California contains waste cooking oil serving as a carbon-rich food source for contaminant-degrading microorganisms.

Continental Steel Corp.

Operation of wind turbines at the Continental Steel Corp. site in Kokomo, Indiana, offsets up to 60% of the grid electricity used to extract contaminated groundwater from 16 wells.

Altus Air Force Base

Use of a continuous one-pass trencher for remedy construction at the Altus Air Force Base in Altus, Oklahoma, reduced fuel consumption while minimizing disturbance to ground surfaces and vegetation.

Re-Solve Inc.

Integration of a bioreactor to degrade contaminants in groundwater at the Re-Solve Inc. site in North Dartmouth, Massachusetts, resulted in an 86 percent reduction in processed chemical usage.

Lawrence Aviation Industries

A groundwater treatment building for the Lawrence Aviation Industries site in Port Jefferson Station, New York, was built to meet selected LEED criteria for green building.

St. Croix Alumina Plant

Onsite solar energy is used to power skimming pumps that recover hydrocarbons from groundwater at the former St. Croix Alumina Plant in Kingshill, U.S. Virgin Islands.

De Sale Restoration Area

About 500,000 tons of byproduct from a local industrial plant was used to stabilize 85 acres of mine-impacted lands at the De Sale Restoration Area in Butler County, Pennsylvania.

Pemaco Superfund site

Restoration of the Pemaco Superfund site in Mayfield, California, included establishing greenspace that promotes rainwater infiltration and minimizes stormwater runoff.

The Policies & Strategies
    Executive Order 14008: Tackling the Climate Crisis at Home and Abroad *New*
    This January 27, 2021, E.O. sets forth policy and initiatives to advance our transition to clean energy and reduction in greenhouse gas emissions. Use of greener cleanup strategies in the U.S. EPA's Superfund and other site cleanup programs helps meet the policy goals by integrating renewable energy, deploying clean fuel and emission technologies, protecting water, sequestering carbon, conserving land, protecting critical ecosystems and biodiversity, and using nature-based solutions.

Learn about footprint assessment tools and view comprehensive reports on footprint evaluations conducted at sites undergoing cleanup. EPA's universal greener cleanup metrics provide a uniform and transparent approach to quantifying the environmental footprint associated with materials, wastes, water or energy that are used or generated during a cleanup. EPA's Spreadsheets for Environmental Footprint Analysis (SEFA) tool is available to help evaluate the environmental footprint of a cleanup project at a detailed level. *Update*
