EPA RCRA ID: MDD981041601
The Resource Conservation and Recovery Act (RCRA) is the public law that creates the framework for the proper management of hazardous and non-hazardous solid waste. Corrective action is a requirement under RCRA that facilities that treat, store or dispose of hazardous wastes, or did so in the past, investigate and clean up hazardous releases into soil, groundwater, surface water and air. For more information, and for more information on RCRA-specific terms used on this page, please visit EPA’s umbrella RCRA web page or EPA’s RCRA Corrective Action page.

Cleanup Activities
The State Highway Administration (SHA) Rosedale Landscape Depot site is located in Rosedale, Baltimore County, Maryland. During past activities at the facility, twenty-two drums of herbicide/pesticide residue were stored on the property. Over time, these drums deteriorated and, when discovered later in 1984, the partially buried drums had released dioxin contamination (specifically 2,3,7,8-tetrachlorodibenzo-p-dioxin or 2,3,7,8-TCDD) over approximately one third of an acre. The dioxin contamination found in the soils was generated as an unwanted by-product during the herbicide manufacturing process. The contaminated soil and remaining drums were removed, confirmation soil samples were taken and a protective, multi-layer cap was placed over the former disposal area to prevent any exposure from residual contamination. Approximately 500 tons of soil and solid materials were removed from the area.
At the time of the excavation, there was not an approved method for disposing of the dioxin- contaminated materials. Therefore, the drums of waste needed to be stored on-site until an alternative could be found. From 1984 to 1988, the drums were stored in temporary containers. SHA determined that a more permanent storage facility was needed for the potential long-term storage of the drums of waste. As a result, a 7,200 square foot storage building with secondary containment was constructed at the facility to more safely house the waste. The SHA received a Maryland state permit to store the hazardous waste in the containment building and performed weekly inspections of the area to ensure no contaminants were being released to the environment. In November 1994, an approved disposal facility for dioxin was located and all dioxin wastes were transported to the company for proper treatment and disposal. SHA proceeded with the clean-closure of the Hazardous Waste Storage building and received approval from the Maryland Department of the Environment in 1995. The building is now used as a maintenance shop and storage.
In the fall of 2000, EPA and SHA reconfirmed that no unacceptable releases have occurred at the facility by taking additional groundwater samples around the former disposal area. Based on this information and the past removal activities, EPA issued a final Agency determination of Corrective Action Complete with Controls. This determination documents that no further corrective action activities are necessary at this time, as long as SHA continues to maintain and annually inspect the existing multilayer cap. EPA and SHA negotiated an agreement (referred to as a Corrective Measures Implementation Agreement) in March 2003, to implement these remaining requirements and ensure long term protection of human health and the environment. SHA submits an Annual Certification report to EPA to document that the existing cap remains in place. As an added measure of long term protectiveness, SHA has placed a notice in the deed for the property that informs any future potential buyers of the residual subsurface contamination. The recording reference for the Deed Notice is 19712/173. It was recorded on March 9, 2004.
EPA requested comments from the public on the proposed Agency determination of Corrective Action Complete with Controls. The public comment period lasted forty-five calendar days. Only one comment was received from SHA with minor changes to the proposal.
On August 11, 2015, the EPA conducted a Long Term Stewardship assessment to assess whether the remedy was implemented and protective of human health and the environment. EPA determined that the remedy institutional and engineering controls have been fully implemented and no control deficiencies were identified.
Cleanup Actions or environmental indicators characterizing the entire facility are shown below. This listing, and all the data on this page, come from EPA’s RCRAInfo and are refreshed nightly to this page. For this table, a blank in the Status column could mean the action either has not occurred or has not been reported in RCRAInfo.

Facility Description
Link to a larger, interactive view of the map.
The Maryland State Highway Administration, Rosedale Landscape Depot facility is located in Rosedale, Maryland, approximately 3,000 feet west of the Route 40 and I-695 interchange outside of Baltimore. The Landscape Depot site is approximately 3.5 acres, while the previously contaminated area of interest occupies one third of an acre of that space. The land use in the area is mixed residential, agricultural and light commercial.
In the past, the main contaminant in the soil was dioxin or 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD). SHA has completed extensive excavation to remove the contaminated soil in 1984, and the area has been covered with a multi-layer cap.
Institutional and Engineering Controls at this Facility
SHA has placed a notice in the deed for the property that informs any future potential buyers of the residual subsurface contamination. The recording reference for the Deed Notice is 19712/173. It was recorded on March 9, 2004.
Institutional and Engineering Controls help ensure human exposure and groundwater migration are under control at a cleanup facility. Where control types have been reported by states and EPA in EPA’s RCRAInfo, they are shown below. Not all control types are needed at all facilities, and some facilities do not require any controls. Where there are blanks, the control types may not be needed, may not be in place, or may not be reported in RCRAInfo.
