Baldwin Waste Oil Company

This former waste oil processing facility in Robstown, Nueces County is currently in the Operation and Maintenance phase of the Superfund Program.

Site Background

The Baldwin Waste Oil site (the site) is located on County Road 44, approximately 0.1 mile west of its intersection with FM 1889, in Robstown, Nueces County, Texas. The property was leased for use as a waste oil processing facility. The site was inspected by the Texas Water Commission in November 1986, and found to be abandoned. The site currently consists of a benzene groundwater plume that is being monitored for natural attenuation.

Superfund Actions Taken to Date

  • October 16, 1987, a legal notice was published in the Texas Register (12 TexReg 3858-3859) proposing the site to the state Superfund registry and announcing that a public meeting to receive citizen comments would be held at the Nueces County Memorial Agricultural Center in Robstown on November 12, 1987.
  • November 1987-July 1992, attempts were made to negotiate funding for the remedial investigation and for removal of contaminated materials from the site.

  • In July 1992, the EPA conducted a removal action. Waste from the tanks and sludge was removed to an off-site incineration facility. The tanks were cut up and removed off site as scrap metal and a pilot-scale bioremediation cell was constructed in the former tank farm area.

  • April 23, 1999, a legal notice was published in the Texas Register (24 TexReg 3245- 3246) announcing a public meeting would be held May 25, 1999, at the Nueces County Auditorium in Robstown to present to the community the best choice among cleanup remedies and to receive citizen comments to be considered in the final recommended remedy.
  • May 25, 1999, a public meeting was held at the Nueces County Auditorium in Robstown to receive comments on the cleanup remedy proposal to monitor the groundwater twice yearly for three years and then once yearly to see if natural attenuation was taking place.
  • June 8, 1999, good-faith offer request letters were sent to potentially responsible parties which asked them to respond with an offer to fund the groundwater monitoring. Responses were due by August 16, 1999.
  • June 29, 1999, TNRCC responded to citizen comments from the May 25, 1999, public meeting.
  • February 29, 2000, TNRCC issued an administrative order setting out the final responsibilities of the potentially responsible party to finish the cleanup. The order set cleanup levels, selected the remedy for cleanup, and established rules, responsibilities and enforcement options for remedial design/remedial action under state Superfund process. TNRCC would be responsible for groundwater monitoring after the cleanup was complete.
  • March 10, 2000, effective date of a TNRCC administrative order. As of the order date, the soil remediation was complete. In the operation and maintenance phase, the groundwater was to be monitored by TNRCC for the effectiveness of natural attenuation.
  • July 3, 2000, the operation and maintenance sampling and analysis plan was approved.
  • July 5, 2000, the operation and maintenance quality assurance project plan was approved.
  • July 13, 2000, monitoring was under way with the first round of groundwater sampling.
  • August 29, 2000, a report was received on results of the first year of natural attenuation of the groundwater to ensure that the concentration of contaminants was being reduced through natural processes.
  • July 17, 2001, groundwater was sampled at the monitor wells to track the natural attenuation of contaminants.
  • December 20, 2001, groundwater was sampled at the monitor wells to track the natural attenuation of contaminants.
  • April 15, 2002, the report was received on results of the second year of natural attenuation of the groundwater to ensure that the concentration of contaminants was being reduced through natural processes.
  • July 30, 2002, groundwater was sampled at the monitor wells to track the natural attenuation of contaminants.
  • September 1, 2002, effective date of the name change from Texas Natural Resource Conservation Commission (TNRCC) to Texas Commission on Environmental Quality (TCEQ).
  • January 9-10, 2003, groundwater was sampled at the monitor wells to track the natural attenuation of contaminants. In addition, an oxygen-releasing compound was added to monitor well 9 to attempt to increase the rate of natural attenuation by increasing the amount of oxygen available in the groundwater.
  • May 29, 2003, semiannual sampling of groundwater was completed.
  • August 19, 2003, TCEQ approved the annual report for the operation and maintenance sampling results.
  • January 30, 2004, groundwater was sampled at the monitor wells to track the natural attenuation of contaminants.

  • September 9, 2008: Monitored natural attenuation of the groundwater is ongoing. Semi-annual sampling indicates that despite some fluctuation benzene levels in the plume are decreasing, particularly in response to the addition of oxygen-releasing compounds. The plume is stable and decreasing in size.
  • April 30, 2009, Monitored natural attenuation of the groundwater is ongoing. Semi-annual sampling indicates benzene levels in the plume are decreasing, particularly in response to the addition of oxygen-releasing compounds. The plume is stable and decreasing in size.
  • October 27, 2009, the second semi-annual groundwater monitoring event was conducted. Previous sampling events indicate benzene levels in the plume are decreasing, particularly in response to the addition of oxygen-releasing compounds. Monitored natural attenuation of the groundwater is ongoing.The plume is stable and decreasing in size
  • May 25, 2011, TCEQ received 2010 Annual Groundwater Monitoring Report (AGMR).
  • June 13, 2011, TCEQ approved the 2010 AGMR. Monitored natural attenuation of the groundwater is ongoing. The 2010 Annual Groundwater Sampling Report indicates benzene levels in the plume are still above the protective concentration level of 5 parts per billion (ppb). The groundwater contaminant plume appears stable and the annual groundwater monitoring will continue.
  • April 13, 2013, the TCEQ sent a letter to the Brownsville Navigation District regarding their AGMRs.
