The Charles Macon Lagoon and Drum Storage site, also known as the Macon Dockery site, operated as a waste oil recycling and antifreeze manufacturing facility. From 1979 through 1981, Mr. Charles Macon operated the site as a waste oil disposal and recycling plant, and an antifreeze manufacturing facility. In May 1981, Mr. Macon leased the recycling plant to C & M Oil Distributors which operated the site until March 1982. The site is comprised of two non-contiguous, independently owned parcels of land: a 40-acre tract owned by relatives of Charles Macon and a 1-acre tract owned by the Dockery family.
Waste oils from facility operations were collected in 11 unlined lagoons, nine above ground tanks, and two tankers on the property and in one unlined lagoon on the Dockery property. Drums containing waste paints, solvents, acids and bases were also received and stored on the Macon and Dockery properties. Operations at the site were terminated following the death of Mr. Macon in 1982.
A 1980 inspection of the site found that waste oil was being stored in 12 unlined and partially lined surface impoundments or lagoons. The lagoons were overflowing and contaminating the surrounding ground. Inspectors also discovered 175 55-gallon drums in various stages of deterioration.
The current land use of the site and surrounding area is primarily agricultural with limited residential use. In addition to residential usage, the site is also used for recreational purposes such as hunting and fishing.
Ground water was found to contain volatile organic compounds (VOCs), notably tetrachloroethene (PCE), trichloroethene, benzene, and vinyl chloride. PCE and polyaromatic hydrocarbons (PAHs) were found in the soil.
Site Cleanup Plan
The Record of Decision (ROD) for the site was issued in 1991. Major cleanup elements for the site included:
- Soil vapor extraction (SVE) of soils in Lagoon 7.
- Bioremediation for Lagoon 10.
- Ground water extraction and treatment via air stripping and ion exchange.
- Off-site disposal of vessel (tanks, tankers, vats, etc) contents and dismantling of the vessels.
Based on treatability study results and additional information regarding the nature of the waste obtained from sampling efforts within Lagoon 10, EPA amended the ROD in June 1994 from bioremediation to excavation and off-site disposal of Lagoon 10 waste materials.
In December 2009, EPA issued an Explanation of Significant Differences to document a final decision to include institutional controls in the form of groundwater use restrictions as part of the groundwater remedy for the Site.
EPA initiated a removal at the Macon site in November 1983. A total of 3,123 tons of waste and 137,000 gallons of oil were removed from the site. Removal operations on the Dockery property began in January 1984. All lagoons were excavated and backfilled with the exception of Lagoon 10. Removal activities at both properties were completed in January 1984.
Remedial activities at Lagoon 10 began in June 1994 and were completed in November 1994.
Construction of the SVE system and the ground water pump-and-treat systems were completed in January 1996. Soil samples collected in 2000 indicated that PCE concentrations were below the cleanup goals for the site, and the SVE system was decommissioned in 2000. The ground water treatment is expected to last approximately 30 years.
Three Five-Year Reviews (FYRs) have been completed for the site, in 2000, 2005, and 2010. The 2010 FYR found that the remedy protects human health and the environment in the short-term, but that institutional controls need to be implemented.
Site cleanup activities have been undertaken primarily by potentially responsible parties (PRPs) with EPA oversight.
On April 14, 1988, EPA entered into an Administrative Order on Consent (AOC) with two PRPs (Clark Equipment Company and Crown, Cork, and Seal Company) responsible for over 50 percent of the volume of waste at the site. The AOC outlined the terms under which EPA would allow the PRPs to conduct the Remedial Investigation/Feasibility Study.
EPA issued a Unilateral Administrative Order in 1992 for long-term Operation and Maintenance (O&M) activities at the site.
EPA has conducted a range of community involvement activities at the Macon Dockery site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process. Outreach activities have included public notices, interviews, and public meetings on cleanup activities and updates.
O&M and ground water treatment at the site continues.
The next FYR will be completed by September 2010.
