Superfund Site Profile
The 48-acre Cedar Chemical Corporation site is located in West Helena, Arkansas. The site is within Helena-West Helena Industrial Park and includes six former production units, support facilities and an office. Operations began at the site in 1970 and included dinoseb production. From 1971 to 2002, manufacturing of agricultural and organic chemicals under various owners and operators took place. Operations contaminated soil, sediment, surface water and groundwater. EPA is working to identify potentially responsible parties (PRPs) for the site. Site investigations are ongoing.
The Environmental Protection Agency (EPA) is in the process of conducting enforcement actions, to identify and notify Potentially Responsible Parties (PRPs) of their obligation to perform cleanup investigations and activities. Notice letters were sent to all liable and viable PRPs on December 31, 2013.
More PRPs have subsequently been identified; therefore, additional notice letters were submitted during the spring 2014. All PRPs have indicated a willingness to cooperate with the EPA. A meeting is tentatively planned for March 2015 with the PRPs to negotiate a consent order to conduct the RI/FS.
