Press Release: Harris County Attorney Vince Ryan is urging the Environmental Protection Agency to require the complete removal of toxic dioxin wastes at a Superfund site on the San Jacinto River.  Waste pits at the site contain a dangerous type of pollutant known as 2,3,7,8-TCDD dioxin, one of the most toxic pollutants in existence making fishing and recreation near the site unsafe.  County Attorney Ryan filed comments on behalf of Harris County and its residents in a letter to the EPA. The letter was released to the public today. In 2008, at the urging of Harris County and others, the site, located in and on the banks of the San Jacinto River near the IH-10 East Bridge in east Harris County, was made a Superfund Site by the EPA. The pits were at one time used to store chemical by-products of paper production. Since that time, by order of the EPA, the responsible parties placed layers of rock and a plastic tarp over the location as a temporary solution to control the leakage.  The parties responsible for the pollution, International Paper, Inc. and MIMC (a subsidiary of Waste Management, Inc.), are proposing a scaled-down remediation plan that would leave toxic and hazardous materials in the environment by simply leaving the “cap” of rock and plastic where it is now.   In his letter, Ryan told the EPA that anything less than complete removal of the toxins would leave the site vulnerable to damage from hurricanes and other severe weather conditions that regularly impact the Texas Gulf Coast.  Despite efforts to educate the public of the contamination dangers, including posted warning signs, the area remains a popular place for fishing and family recreation.  “The Waste Pits are located in an area of the San Jacinto River that is the locale of boating, swimming, camping, commercial and recreational fishing,” County Attorney Ryan said. “Removal of the source material from the Waste Pits and the river sediment is the only way” to ensure that humans and wildlife are no longer exposed to 2,3,7,8-TCDD.
