Background

Current Status

The EPA is currently monitoring the ground water (i.e., monitored natural attenuation) at the Site according to the ROD for Operable Unit 1 and an agreement with the purchaser of the Site.  On February 4, 2010, a contractor for the purchaser of the Site, requested that the EPA delete the soils and the 8-acre western ground water portion of Operable Unit 1 in order to facilitate the redevelopment of the 35-acre Site.  The Federal Register Notices, announcing the proposed partial deletion of the Site, were published in the Federal Register on June 15, 2010.  These notices announced a thirty-day public comment period which began on June 15, 2010 and ended on July 15, 2010.  The partial deletion became effective on August 16, 2010, since the EPA received no adverse comments from the public before the end of the public comment period.  This partial Site deletion does not preclude future actions under Superfund.  The agreement with the purchaser of the Site is discussed in more detail in the “Record of Decision” section of this summary.  Additionally, the “First Five-Year Review (FYR) Report” for the Site has been completed. The purpose of the FYR is to ensure that the final remedy for the Site remains protective of human health and the environment.  The EPA is currently implementing the recommendations in the FYR Report. 

Site Background

The Many Diversified Interests, Inc. site is located in Houston, Texas. The area includes a 35-acre tract of land that was a former foundry from 1926 to 1992, residential yards and High Access Areas. EPA believes that air emissions from the former foundry may have contaminated soils on and off site. Following cleanup, EPA took part of the site off the Superfund program’s National Priorities List (NPL) in 2010. Following construction of the site’s remedy, groundwater monitoring is ongoing.

National Priorities Listing (NPL) History
Proposal Date: September 29, 1998.
Final Listing Date: January 15, 1999.
Population: According to Census data from the year 2000, there were 3,952 persons living within ½ mile of the MDI Site, with a minority percentage of 98.9%.

What Is Being Done to Clean Up the Site?

The site is being addressed through federal, state and potentially responsible party (PRP) actions.

EPA has conducted several five-year reviews of the site’s remedy. These reviews ensure that the remedies put in place protect public health and the environment, and function as intended by site decision documents. The most recent review concluded that response actions at the site are in accordance with the remedy selected by EPA and that the remedy continues to be protective of human health and the environment.

What Is the Current Site Status?

The site’s long-term remedy included excavation and disposal of contaminated debris and soils, and implementation of institutional controls to prevent exposure to contaminated soil and groundwater. The remedial action for the soils involved removing lead-contaminated soils from 155 residential yards and finished in 2008. EPA is monitoring groundwater.

Following cleanup, EPA took part of the site off the NPL in 2010.

EPA’s Involvement at the Site

In 1926, Texas Electric Steel Casting Company (TESCO) began operating a metal casting foundry at the site. TESCO built a second foundry on the eastern portion of the site in 1970. TESCO primarily manufactured specialty molded parts such as large wheels, tracks and mining equipment.

Emergency Response and Removal

Cleanup has also included removal actions, or short-term cleanups, to address immediate threats to human health and the environment. A removal action in 1998 removed contaminated soil from 89 residential yards. Another removal action in 2003 removed contaminated soils from 57 residential areas.
