Current Site Status
The Chevron Chemical Company (Ortho Division) site includes approximately 4 acres of industrial property. EPA placed the site on the National Priorities List (NPL) in 1994 because of contaminated soil and ground water resulting from past operations. EPA, the Florida Department of Environmental Protection (FDEP) and Chevron, the site’s potentially responsible party (PRP), 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. Nearby residents and businesses use the public water system for drinking purposes. Fencing prevents access to the site. By conducting ongoing ground water monitoring and required Five-Year Reviews, EPA, FDEP and the site’s PRP continue to protect people and the environment from site contamination.
Site Location and Background
The 4.39-acre site is located at 3100 North Orange Blossom Trail (U.S. Highway 441) in Orlando, Florida. The site is cleared, vegetated with grass, fenced and unoccupied. Light industrial land uses are located south and west of the site. Lake Fairview Commerce Center is located directly across Orange Blossom Trail to the east. The nearest residential property is a trailer park, located across North Orange Blossom Trail to the northeast. In addition, one resident now lives in a building located on the former Armstrong Trailer Park property immediately north of the site.
Between 1950 and 1976, a pesticide formulation plant operated at the site. A truck repair business operated at the site from 1978 to 1986. In 1994, EPA listed the site on the NPL.
Site investigations identified contamination in soil and ground water that could potentially harm people in the area. Soil and ground water contamination resulted from waste handling practices at the site. Contaminants of concern identified include pesticides, volatile organic compounds such as xylene and metals.
The site is unoccupied and fenced to restrict access. A land use restriction on the site property prohibits placement of ground water wells. Residents do not use ground water in the upper-level aquifer as a source of drinking water. All properties located downhill from the site connect to the public water system. Based on a well survey conducted in 2008, the nearest residence that relies upon well water is located approximately one mile northeast of the site. No private wells are currently located in the area of ground water contamination.
Investigation and Cleanup Responsibility / Oversight
The PRP leads site investigation and cleanup activities, with oversight provided by EPA and FDEP.
Site Cleanup Plan
In 1996, EPA issued a cleanup plan (a Record of Decision, or ROD) for the site. The plan included the following activities:
- Using institutional controls to prevent use of contaminated ground water.
- Conducting site maintenance such as fence upkeep and grass mowing.
- Using monitored natural attenuation.
- Using a different ground water cleanup plan in case natural processes do not successfully break down contamination.
The ROD also determined that additional soil cleanup was not necessary.
In 2010, EPA issued an Explanation of Significant Differences (ESD) after implementing the contingency cleanup plan.
Parties have taken several cleanup actions at the site. Between 1991 and 1992, the PRP demolished and removed all site structures during short-term cleanup actions. The PRP excavated, or dug up, and shipped off site almost 18,000 tons of pesticide-contaminated soil for proper disposal. The PRP treated ground water encountered during the excavation on site.
In 1994, the PRP excavated and shipped off site approximately 230 tons of pesticide-contaminated soil for proper disposal.
In 1997, the PRP completed installation of ground water monitoring wells.
In 2004, the PRP found site contaminants in monitoring wells uphill from Lake Fairview. As a result, the PRP implemented the contingency cleanup plan described in the ROD. The PRP increased the frequency of ground water monitoring in existing wells from annual to quarterly monitoring and installed more monitoring wells. EPA undertook a ground water cleanup pilot study using permeable reactive barriers. The PRP evaluated the amount of remaining contamination in site soils.
EPA documented these actions in the ESD in September 2010. EPA installed over 10 permeable reactive barriers as part of the ground water cleanup pilot study. The PRP continues to study the movement of ground water contamination, as there is evidence that ground water contamination has not yet been fully contained. In addition, the PRP will remove over 3,000 cubic yards of contaminated soil remaining on site. This will address the primary source of site contamination.
EPA negotiated legal agreements with the site PRP, Chevron, to investigate and clean up the site. The PRP continues to fund site cleanup, monitoring and oversight activities.
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 information meetings on cleanup progress and activities. In 2010, EPA made the ESD available for public comment.
A ground water cleanup pilot study is underway.
Ground water monitoring is ongoing.
EPA completed the last Five-Year Review in 2008 and plans to complete the next Five-Year Review in 2013.
EPA keeps additional site documents and information in a site information repository at the location below. EPA also posts site documents, when available, on EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office.
