The U.S. Environmental Protection Agency (EPA) has started its fifth Five-Year Review for the Hassayampa Landfill Superfund site cleanup plan. The 10-acre site is about 10 miles west of Buckeye, Arizona. Maricopa County formerly used the site for hazardous waste disposal. In 1992, EPA issued its cleanup plan for the site. Cleanup work began in 1994.
Federal law requires EPA to review its cleanup plans every five years if:
- a cleanup takes more than five years to complete; or
- hazardous waste is still on-site
The Five-Year Review will show if the cleanup plan continues to work as designed. EPA did the last such review in 2016 and the next one is due by Sept. 30, 2021.
What does the review include?
The 2021 Five-Year Review includes:
- an inspection of the site and its cleanup technologies;
- a review of site data and maintenance records; and
- a review of any new laws or requirements that could affect the cleanup.
