Current Site Status

The Anaconda Aluminum Co./Milgo Electronics Corp. site includes the area where electrochemical aluminum coating operations took place from 1957 until 1984. EPA placed the site on the National Priorities List (NPL) in 1990 because of contaminated ground water and soil resulting from facility operations. EPA, the Florida Department of Environmental Protection (FDEP), and Anaconda Aluminum Company and Milgo Electronics Corporation, the site’s potentially responsible parties (PRPs), have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. After PRPs removed all soil contamination, EPA determined that the site no longer threatened people living or working near the site or the environment. EPA did not require further cleanup activities and deleted from the NPL in 1998.

Site Location and Background

The 3-acre site is located at 3630 Northwest 76th Street in an industrial area in Miami, Florida. Electrochemical aluminum coating operations occurred at the site from 1957 until 1983. The site includes a 1-acre area where Anaconda Aluminum Company operated from 1971 until 1983 and a 0.5-acre area where Milgo Electronic Corporation operated from 1961 until 1984. A mobile home park borders the site to the east. Railroad tracks border the site to the south. Industrial and commercial businesses border the site to the north and west. Surrounding land uses include industrial, commercial and residential land uses.  Several other Superfund sites are located within a few miles of the site. In 1990, EPA listed the site on the NPL.

Site Cleanup Plan

In 1994, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan documented EPA’s decision that no cleanup action was required. The plan included quarterly monitoring of on-site ground water for one year to confirm the appropriateness of the no-cleanup action plan.

Summaries of site cleanup approaches are also available online in key site cleanup documents, including the ROD.

Cleanup Progress

In 1993, site PRPs removed all contaminated soils. Follow-up investigations confirmed that the site no longer posed a threat to public health or the environment. PRPs completed required ground water monitoring in 1995. In 1998, EPA determined that the site did not threaten human health or the environment and deleted the site from the NPL.

Enforcement Activities

EPA negotiated legal agreements with the site’s PRPs to investigate and clean up the site. The PRPs funded site cleanup, monitoring and oversight activities.

The ROD online provides additional information on specific legal agreements for the site.
