Current Status

The St. Augustine Gas Company site includes the area where St. Augustine Gas Company operated a manufactured gas facility from 1885 until the late 1950s. EPA did not list the site on the National Priorities List (NPL) of contaminated sites but considers it an NPL-caliber site and is addressing it through the Superfund Alternative Approach. EPA, the Florida Department of Environmental Protection (FDEP), and Atlanta Gas Light Company and the City of St. Augustine, 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. Site contamination does not currently threaten people living and working near the site. A water line connects residences and businesses near the site to the public water supply. By monitoring ground water, EPA, FDEP and the site’s PRPs continue to protect people and the environment from site contamination.

Site Location and Background

The 10-acre site is located in downtown St. Augustine, Florida.acant land makes up the majority of the site. The San Sebastian River borders the site to the west and residences and commercial businesses border the site to the north, south and east. Commercial, light industrial and residential land uses surround the site. The site includes the area where St. Augustine Gas Light Company operated a manufactured gas plant from 1885 until the late 1950s. Plant operations contaminated the site with coal tar, a byproduct of the gas production process. The nearest public water supply well, located 1.5 miles from the site, has not been impacted by site contamination. The current owner of the site, REDUS Florida Commercial, LLC, anticipates redeveloping the site into a marina with residential and commercial land uses.

Threats and Contaminants

Site investigations found contamination in ground water, soil and sediment that could potentially harm people in the area. Ground water, soil and sediment contamination resulted from waste handling practices at the site. Contaminants of concern include volatile organic compounds (VOCs), metals, inorganics and polycyclic aromatic hydrocarbons (PAHs). Soil contamination also included dioxins, which were not associated with former site operations.

Plant operations left coal tar, a byproduct of the gas production process, at the site. Contamination at the site extended to a depth of approximately 10 feet in the former plant area and to 30 feet beneath the former gas plant engine room. Sediment contamination extended to depths of one to three feet.

Site Cleanup Plan

In 2000, site PRPs completed an analysis of options for removal and cleanup. EPA recommended a cleanup plan based on the analysis that included the following activities:

Cleanup Progress

Site PRPs dug up approximately 85,000 tons of contaminated soil and sediment and disposed of it off site. PRPs then backfilled and reseeded the area. The PRPs installed a ground water monitoring system and completed cleanup activities in 2002. Monitored natural attenuation and sampling of ground water monitoring wells began in 2003 and is ongoing. The site now supports commercial and residential land uses.

Site redevelopment into a marina complex began in 2005 but stopped in 2008 due to limited financial resources. The site owner completed dredging of the new marina entrance channel and filling the entrance with water in 2007.

Enforcement Activities

EPA negotiated legal agreements with the PRPs to investigate and clean up the site. Site PRPs continue to fund site cleanup, monitoring and oversight activities.

Community Involvement

EPA has worked with the community and its state partner to develop a long-term cleanup approach for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.

EPA has conducted a range of community involvement activities at the site to solicit community input and to make sure that the public remains informed about site activities throughout the cleanup process. Outreach efforts have included public notices, interviews and public meetings on cleanup activities and updates.

Future Work

PRPs completed soil and sediment cleanup activities in 2002. PRPs will continue to monitor ground water. The site owner plans to continue with the site’s redevelopment when funding becomes available.
