EPA: YEAH, BETTER CLEAN OUT THE DIOXIN PITS FROM THE SAN JACINTO RIVER NOW THAT THEY’VE LEAKED A bit later than had been urged by those alarmed by the longterm presence of pits full of toxic waste sealed only with a tarp on top hanging out in the San Jacinto River, the EPA has now approved a plan to remove most of the dioxin stored within them. “As exemplified today, EPA is prioritizing Superfund clean-up by making decisions in a decisive, timely manner,” reads a statement from administrator Scott Pruitt released this afternoon. “The San Jacinto Waste Pits site was added to the National Priority List nearly a decade ago.” What’s the rush? As predicted by EPA studies and many a casual observer, the pits appeared to have leaked extensively after Hurricane Harvey flooding. Under the new $115 million plan, cofferdams will be installed around the pits and almost 212,000 cubic yards of dioxin-contaminated material will be excavated — leaving just enough behind that the agency can, it says, ensure controls that will “prevent access, eliminate off-site migration, and monitor the natural recovery into the future.” [EPA; more info; Houston Chronicle; previously on Swamplot] Video of waste pits after Harvey flooding: Greg Moss

HOW TO PREPARE SAN JAC RIVER STEW What’s the local recipe for that San Jacinto River fishin’ favorite, toxic redfish? “The dioxins come from submerged waste pits north of the Interstate 10 bridge. McGinnes Industrial Maintenance Corp., which is no longer in business, owned and operated the pits in the 1960s, filling a 20-acre site on dry land with waste from a now-closed paper mill near the Washburn Tunnel. In the bleaching process, paper mills generated large amounts of dioxins, a family of compounds so toxic that scientists measure them in trillionths of a gram. The EPA says there is no safe level of exposure to the chemicals, which are known to cause cancer and disrupt immune and reproductive systems. The San Jacinto River began to run through the waste pits by the early 1970s because of subsidence — the sinking of soft soils as water is pumped from underground. With the McGinnes pits under water, the dioxins spread into the river and worked their way through the ecosystem, becoming more concentrated at each step in the food chain. For more than a decade, the Texas Department of Health has warned that fish and crab caught along this stretch of water, north of the Lynchburg Ferry, are tainted with cancer-causing dioxin, pesticides and PCBs. . . . In July, the EPA identified the International Paper Co. and McGinnes, which became part of Waste Management through a series of mergers and acquisitions, as the firms responsible for the dioxins problem. Under the Superfund law, the two companies will be required to evaluate and clean up the contamination. They paid about $65,000 for the fencing and roughly 50 warning signs in English, Spanish and Vietnamese, a McGinnes spokesman said.” [Houston Chronicle]
