Industrial Road/Industrial Metals
The Industrial Road/Industrial Metals site (the site) at 3000 Agnes Street, occupies an 8 acre tract in a residential, light industrial, and commercial area of Corpus Christi. The site began operation in 1937, and operated as a metal salvage company, dealing mainly in cracked lead acid batteries and copper coils removed from electrical transformers, under a series of owners until lead battery operations were stopped in mid-1980. During operations, cracked battery cases would be stored on the property and used for fill on the northern portion of the site. Salvaged copper coils from transformers would be burned to remove the insulation; polychlorinated biphenyl (PCB) oil from the transformers would be poured onto the ground, spread on the road to control dust, saved to wash parts, or burned for fuel in the winter. A Corpus Christi-Nueces County Department of Public Health and Welfare inspection of the site in early 1981 revealed piles of cracked batteries, whole batteries and lead stored in piles in an area one to two acres in size. At that time, the county health department recommended that the old acid neutralization pit be covered or drained, battery cases removed and the site sampled for heavy metals. The sampling revealed high levels of both lead and PCBs impacting approximately 1500 cubic yards of soils. A closure plan was approved by the State of Texas that called for excavation and removal of contaminated soil. The transportation and disposal of PCB and lead contaminated soil was completed in 1990. The site is currently inactive.
Superfund Actions Taken to Date
- June 2002, a hazard ranking system (HRS) documentation record was prepared for the Industrial Road/Industrial Metals site.
- January 23, 2004, a legal notice was published in the Texas Register (29 TexReg 676-677) describing the site and proposing the site for listing on the state Superfund registry. A public meeting to receive citizen comments is scheduled for February 26, 2004, at Miller High School.
- January 2004, TCEQ began mailing out requests for good faith offers from potentially responsible parties, asking them to enter into an agreed order to fund or perform a remedial investigation and feasibility study at the site. The deadline to respond was April 26, 2004.
- February 10, 2004, a community relations plan was prepared for the Industrial Road/Industrial Metals site.
- February 26, 2004, a public meeting was held at Miller High School to receive community comments on the proposal to list the Industrial Road/Industrial Metals site on the Superfund registry and to propose commercial/industrial land use specifications for remediation of the site contamination. Land use designation may impact the remedial action proposed for the site.
- April 26, 2004, no good-faith offers were received from potentially responsible parties by the deadline to enter into an agreed order to fund or perform a remedial investigation and feasibility study.
- June 21, 2004, TCEQ issued a work order to its contractor to finalize and implement the field sampling plan that has been prepared by the project manager. The order begins the remedial investigation at the site.
- July 20-21, 2004, the TCEQ contractor conducted field sampling as specified in the field sampling plan.
- August 2004, the site was cleared of brush and mowed. The site clearing generated much more debris than had been anticipated.
- September 2004, analytical results from the additional sampling done in July were
received and accepted.
- December 2004, the TCEQ project manager visited the site to survey possible locations for installation of new monitoring wells.
- June 2006, groundwater samples were collected from all monitor wells. Analysis results indicate that arsenic, cadmium, lead, and manganese exceed protective concentration levels in monitor well No. 4A and monitor well No. 2A. Arsenic and manganese exceed protective concentration levels in monitor well No. 3A. In monitor well 4A, 1,2-dichloroethane exceeds the protective concentration level. It was decided to begin coordinating with the contractor to install additional wells to identify the limits of groundwater contamination.
- November 2006, groundwater samples were collected from the onsite wells.
- December 1, 2006, two damaged areas of the perimeter fence were repaired.
- February 2007, site was mowed and contamination warning signs were replaced around the perimeter of the property where necessary.
- March 2007, groundwater samples were collected from all onsite monitoring wells.
- May 23, 2007, results from the March groundwater sampling indicate arsenic exceeds protective concentration levels in monitor wells 5A, 2A and 3A; cadmium exceeds protective concentration levels in monitor well 2A: lead exceeds protective concentration levels in monitor well 2A, and 1.2 dichloroethane exceeds protective concentration levels in monitor well 4A.
- August 2007, results from the June groundwater monitoring event indicate exceedance of the protective concentration level of manganese in monitor well 5A, an exceedance of arsenic and lead in monitor well 2A, and an exceedance of arsenic in monitor well 3A.
- April 23, 2010, A site inspection was conducted by TCEQ.
- July 2011, the on-site building was demolished and removed, the clay capped area was mowed and cleared of trees and brush, and the security fence was repaired. Additional investigation work is planned at the site in fiscal year 2012.
- July 2012, On-site mowing, cap maintenance and fence repair was completed.
- August 2012, Installation of two offsite background monitoring wells and routine sampling of the on-site monitoring wells was completed.
- September 2012, development of a Remedial Investigation work plan is in progress to address off-site lead concentrations in the soil adjacent to the southern boundary of the site.
- December 2012, a Remedial Investigation work plan has been completed to address off-site lead concentrations in the soil adjacent to the southern boundary of the site.
- February 2013, a Remedial Investigation Technical Memorandum was completed which determined that the uppermost groundwater bearing zone under the site is a Class 3 aquifer.
