Fact Sheet

Engineering Evaluation/Cost Analysis Released for Comment, 12th Avenue Solvents Superfund Site, Ava, Missouri


EPA Region 7 is hosting a public meeting from 7 p.m. to 9 p.m. on Thursday, March 5, 2009, at Ava Middle School Cafeteria to present the Engineering Evaluation/Cost Analysis (EE/CA) proposed for the 12th Avenue Solvents Site. The EE/CA describes recommended removal actions to address source material contamination at the site. EPA, Missouri Department of Natural Resources (MDNR) and company representatives will be available to provide details about the proposed EE/CA and to answer questions from the public.


The 12th Avenue Solvents Site includes the former Rawlings facility, a portion of the Douglas County Department of Health property, a portion of the Sentinel Wood treating property and all of the former Emerson Motor Company (EMC) facility. In September 2001, EPA, MDNR and Emerson Electric Co. (Emerson) signed an agreement which required Emerson to conduct investigations and cleanup actions at the site. By the end of 2008, over 25 million gallons of ground water have been treated and over 4,300 pounds of contaminants have been removed through Emerson-funded treatment systems at the site.


You are invited to attend a public meeting to learn more about the proposed EE/CA for the 12th Avenue Solvents Site. The meeting is scheduled: 

Thursday, March 5, 2009
7 p.m. to 9 p.m.
Ava Middle School Cafeteria
507 NE 3rd Street
Ava, Missouri


The EE/CA was conducted to identify and evaluate potential non-time critical removal actions for addressing remaining source material contamination at the site. During the EE/CA study, the following removal action alternatives were evaluated for the site:

Each of these alternatives was evaluated using the criteria of effectiveness, implementability, and cost. Based on this comparative analysis, EPA, MDNR and Emerson recommend Alternative 6 for addressing contamination at the site.


Alternative 6 was determined to be the most effective removal alternative because it will result in permanent and significant reduction of the total mass of contaminants of concern in ground water and control further migration of affected ground water. This alternative also protects utility and construction worker exposure to contaminants of concern during any utility trench evacuation by placement of institutional controls.


EPA has compiled the administrative record for the site. The administrative record contains the proposed EE/CA and may be reviewed during normal business hours at the following locations:

Douglas County Public Library
301 S.W. 3rd Avenue
Ava, Missouri

EPA Region 7

Please submit your comments by mail or electronically to Dianna Whitaker at the address shown below no later than April 6, 2009.
