- September 28, 2016 – EPA Press Release on Proposed Plan for Cleanup & Public Comment Period
The Galveston Bay Foundation wants you to be informed about the cleanup of the San Jacinto River Waste Pits Superfund Site (SJRWP) and learn how you can have a voice in the process!
In 2011, GBF received a grant from the U.S. EPA to hire scientists from the Houston Advanced Research Center (HARC) to serve as the independent technical advisors and review site cleanup process reports, provide expert input, and communicate their findings to the public. These findings will be posted on this webpage and communicated to the public via e-mail, meetings, and print materials.
In the mid-1960s, the pits north of I-10 received wastes from the former Champion Paper mill located in Pasadena, Texas. The paper mill wastes contained dioxins, which are extremely toxic and can cause increased risk of cancer and other threats to human health such as liver damage and birth defects. The abandoned pits, like the rest of the surrounding area subsided (the sinking of land as the result of groundwater pumping) and the dioxin-laden wastes have been exposed to the waters and sediments of the San Jacinto River for decades. The pits are now partially submerged in the river and are often completely inundated by high river flows or high tide events.
The SJRWP was added to the National Priorities List of hazardous waste sites in 2008. As a result the U.S. Environmental Protection Agency (EPA) began overseeing the Superfund process cleanup of the pits, which is being performed by International Paper (IP) and McGinnis Industrial Maintenance Corporation (MIMC), the potentially responsible parties (PRPs) for the pollution at the site. Given the immediate threat to human and environmental health, EPA directed the PRPs to install a temporary armored cap on the pits north of I-10. The cap was completed in July 2011.
Two other critical exposure paths have been characterized at this site. Before the pits were temporarily capped, people recreating, fishing, or crabbing at the site could come into direct contact with the dioxins through dermal absorption (absorption of dioxin through the skin) as their bare skin came into contact with the wastes or through accidental ingestion of contaminated sediments, e.g. children on the site placing their hands contaminated with the waste into their mouths.
Given the chemical nature of dioxins, including its relative insolubility in water, and the characteristics of the SJRWP, people are not expected to be exposed to contaminants from airborne dust, groundwater, or surface water. For more information on the routes of exposure to SJRWP dioxins, see the Public Health Assessment – Final Version that was prepared by the Texas Department of State Health Services.
|Activity||Description||Start Date||Completion Date|
|Discovery the Site||Texas Parks and Wildlife Department became aware of information suggesting the presence of waste pits in and adjacent to the San Jacinto River and notified the Texas Commission on Environmental Quality.||April 2005||n/a|
|Placement on National Priorities List||The U.S. EPA’s listing of the site on the NPL made it a “Superfund” site, eligible for further investigation and action.||March 2008||n/a|
|Time Critical Removal Action (TCRA)||A short-term stabilization/capping of the waste pits by the responsible parties. In this case, an armored cap was placed over the waste pits to temporarily address the release of dioxin into the San Jacinto River.||April 2010||July 2011|
|Remedial Investigation / Feasibility Study (RI/FS)||The process of data collection and analyses of the site problem, identification of cleanup alternatives, and the recommendation of a clean-up remedy (see links to these documents under Key Cleanup Documents and Our Technical Reviews/Summaries below).||December 2009||September 2016|
|EPA Proposed Plan for Cleanup Public Comment Period||On September 28, 2016, U.S. EPA announced their Proposed Plan for Cleanup (see link to this document under Key Cleanup Documents and Our Technical Reviews/Summaries below). The official public comment period began on September 29, 2016. The EPA has extended the public comment period until January 12, 2017. See the EPA press release near the top of this webpage for details on how you can submit comments.||September 29, 2016||January 12, 2017|
|EPA Record of Decision (ROD)||The U.S. EPA’s public document that explains which cleanup alternative(s) will be used at the site. The ROD is based on information and technical analysis generated during the RI/FS and consideration of public comments and community concerns.||January 13, 2017||Late 2017 (tentative)|
