Tricon America, Inc.

No further Superfund environmental response actions are required on this former aluminum and zinc smelting and casting facility in Crowley, Tarrant County.

Site Background

The Tricon America, Inc. site (the site) occupies approximately 5 acres at 101 East Hampton Road within the city limits of Crowley. The site is bordered by the Northern Burlington and Santa Fe Railroad tracks and a manufacturing facility to the west, Hampton Road to the south, and Deer Creek, a small creek in the watershed of Lake Arlington, is within 150 feet of the northern boundary of the site. The east side of the site abuts a city of Crowley maintenance yard and some private residences. From 1978 to 1984, the property had been used as an aluminum and zinc smelting and casting facility. An ash pile from the smelting and casting operation is the area of concern. Tricon America, Inc., purchased the property in 1985 and manufactured prefab concrete walls, and assembled fiberglass buildings on the site until a bankruptcy filing in 1989. Batch ends and off-spec batches of concrete were dumped on top of the ash pile. The pile is approximately 300 feet by 80 feet on the top side and 24 feet high. It was estimated the pile contained about 21,000 cubic yards of ash.

Superfund Actions Taken to Date

  • In 1989, the Texas Water Commission (predecessor agency to TNRCC) conducted a removal action of contaminated soil from adjacent residential lots.
  • In April, 1990, the EPA conducted an emergency action to consolidate the majority of ash on the edge of a cliff on the north of the facility. It contained approximately 21,000 cubic yards of material. The pile was stabilized with a tar-like sealant.
  • November 1990, the EPA acted to further limit dangers that contaminants may have posed by capping the ash pile with a 40 mil plastic liner and covering it with Triloc blocks. EPA also fenced the site to limit unauthorized access.
  • January 1991, the EPA decided no further federal Superfund action would be needed.
  • July 26, 1991, a legal notice was published in the Texas Register (16 TexReg 4102- 4103) describing the site, proposing the site to the state Superfund registry, and announcing that a public meeting to receive citizen comments would be held at the H.F. Stevens Middle School in Crowley on September 26, 1991.
  • July 1991, the site perimeter fence was upgraded and signs were posted every 100 feet warning of contamination.
  • July 15, 1993, emergency removal of 2,000 cubic yards of lead-contaminated soil from a residential backyard adjacent to the site was completed.
  • September 1, 1993, effective date of the creation of the Texas Natural Resource Conservation Commission from the joining of the Texas Water Commission and the Texas Air Control Board and a portion of the Texas Department of Health.
  • April 1994, remedial investigation under way
  • January 1995, a community relations plan was prepared for the Tricon America, Inc., Superfund site.
  • March 9, 1997, the final report was approved, marking completion of the remedial investigation phase.
  • September 1998, a focused feasibility study identified and evaluated remedial alternatives for the site.
  • December 1998, additional sampling was performed to define the extent of contamination in surface and shallow subsurface soils on the Tricon America, Inc. facility and Deer Creek floodplain. No contaminated soil was found in the Deer Creek floodplain.
  • March 25, 1999, TNRCC estimated approximately 180 cubic yards of contaminated soil remained outside of the Triloc cap.
  • April 2, 1999, a geotechnical investigation of the Triloc cap showed minor repairs were needed to restore full integrity. The stability of the slope was satisfactory.
  • July 22, 1999, a legal notice was published in the Crowley Star Review announcing a public meeting was to be held August 26, 1999, at the Crowley City Hall to present to the community the best choice among cleanup remedies and to receive citizen comments to be considered in the recommended remedy, which was repair of the contaminant cell cap and installation of a French drain.
  • July 23, 1999, a legal notice was published in the Texas Register (24 TexReg 5798-5799) announcing a public meeting was to be held August 26, 1999, at the Crowley City Hall to present to the community the best choice among cleanup remedies and to receive citizen comments to be considered in the recommended remedy, which was repair of the contaminant cell cap and installation of a French drain.

The revised remedy would be to excavate the Tri-Loc cap area waste and dispose of it off-site, which would eliminate the need for engineering controls and monitoring, since all contaminated material above the action level would be removed.
  • January 6, 2000, a proposed remedial action document was prepared for the Tricon America, Inc. site.
