Current Site Status

The Sanford Gasification Plant (SGP) site includes an area where water gas and carbureted water gas manufacturing took place from the 1880s until 1951. EPA did not list the site on the National Priorities List (NPL) but considers it an NPL-caliber site and is addressing it through EPA’s Superfund Alternative Approach. EPA, the Florida Department of Environmental Protection (FDEP) and the site’s potentially responsible parties (PRPs), the Sanford PRP Group, 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 nearby residents and businesses to the public water supply. By monitoring ground water, working to place institutional controls on the site property and planning to undertake Five-Year Reviews, EPA, FDEP and the site’s PRPs continue to protect people and the environment from site contamination.

Site Location and Background

The site is located in Sanford, 25 miles northeast of Orlando, in Seminole County, Florida. The site includes the former SGP facility, an unnamed tributary and Cloud Branch Creek from the unnamed tributary to where the creek discharges into Lake Monroe. Residences and commercial businesses border the site.

From the 1880s until 1951, manufacturing of water gas and carbureted water gas took place at the site. Manufacturing operations included carbonization or destructive distillation of bituminous coal and coke. Operations generated waste, including tars and condensates, and stored the waste in gas holder tanks on site. The Florida Public Utilities Company (FPUC) currently owns most of the site. FPUC  maintained an office and natural/propane gas distribution facility at that property until 2002 FPUC relocated its operations. EPA did not list the site on the NPL but considers it an NPL-caliber site and is addressing it through the Superfund Alternative Approach. Currently, the site is not in use.

Threats and Contaminants

Site investigations found contamination in ground water, soil and sediment that could potentially harm people in the area. Contamination resulted from waste handling practices at the site. The primary contaminant of concern is polycyclic aromatic hydrocarbons (PAHs).

EPA and the site’s PRPs have addressed soil and sediment contamination.

EPA is working to place institutional controls on the site property to restrict digging and ground water well installation.

The PRPs continue to monitor ground water contamination at the site. EPA does not consider ground water a threat because people do not access ground water for any purpose and, the area will be designated as a Groud water Use Advisory Zone to prevent future drinking water wells from being installed before the ground water has been restored.

EPA considered children’s health issues as part of the site’s risk assessment.

Investigation and Cleanup Responsibility / Oversight

The site’s PRPs lead site investigation and cleanup activities, with oversight provided by EPA and FDEP.

Site Cleanup Plan

Site investigations and cleanup activities have focused on three areas, which EPA refers to as operable units, or OUs. These areas include OU-1: contaminated soil; OU-2: ground water; and OU-3: sediments in Cloud Branch Creek and the Lake Monroe delta.

In 2000, EPA issued a cleanup plan (a Record of Decision, or ROD) for OU-1. While preparing to implement the cleanup plan, the site’s PRPs identified additional soil contamination. As a result, EPA issued an amendment to the cleanup plan (a ROD Amendment) in 2006 to update the cleanup plan. The amended plan included the following activities: 

In 2001, EPA issued a cleanup plan (a ROD) for OU-2. The plan included the following activities:

In 2006, EPA issued a cleanup plan (a ROD) for OU-3. The plan included the following activities:

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

Cleanup Progress

In 2009, the site’s PRPs began cleanup activities. The PRPs stabilized 142,000 cubic yards of soil, removed and disposed of contaminated surface soil, collected and treated water in contact with waste, and restored 2,300 feet of creek bed.

The water collection and treatment system operated from 2010 until 2011. The system treated 17.6 million gallons of water and discharged it to the sanitary sewer system.

In 2011, the PRPs completed cleanup activities at the site. The PRPs also completed construction of permanent wells in 2011 and installed a ground water monitoring system. The PRPs also began monitored natural attenuation.

EPA, the PRPs, the remedial oversight contractor and the remedial construction contractor adopted and implemented green best management practices that reduced the environmental carbon footprint of cleanup activities.

In 2012, the PRP group submitted the Remedial Action Report and Construction Completion report for the site and it was approved in August 2012. Currently OU1 AND OU3 have certificates of completion, and OU2 will be monitored until all the remedial goals of the ROD have been met and it too will qualify for a certificate of completion. The first Five-Year Review is scheduled for completion in December 2014. By undertaking Five Year Reviews EPA, FDEP and the site's PRP continue to protect people and the environment from the site contamination.

Enforcement Activities

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

RODs and the ROD Amendment online provide information on specific legal agreements for the site.

Community Involvement

EPA has worked with the community and its state partner to develop a long-term cleanup plan 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 to solicit community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts have included public notices and public meetings.

Future Work

Ground water monitoring is ongoing.

EPA is working to place institutional controls on the site property to restrict digging and ground water well installation.

EPA plans to complete the first Five-Year Review for the site in 2013.
