ARMY EXPECTS NO SIGNIFICANT IMPACTS FROM TRANSPORTING WASTE


Transporting liquid waste from a chemical weapons neutralization facility in Indiana to a commercial waste treatment plant in New Jersey will have no significant adverse environmental impacts, according to an Army draft
revised finding of no significant impact (FONSI).

The document updates a 2002 environmental assessment and specifically addresses transportation from the Newport Chemical Depot to the DuPont Chambers Works Plant because the New Jersey facility has now been identified as a potential treatment, storage and disposal facility (TSDF) for the liquid effluent, or hydrolysate, from the neutralization of VX nerve agent at Newport. Earlier plans to ship the waste to an Ohio site were aborted following a community uproar over the project.

"Evaluation of transportation routes show that there is not expected to be an increased risk to the public or environment from transporting the hydrolysate from Newport, Indiana to Deepwater, New Jersey, and DuPont has the necessary permits to transport and dispose of the liquid effluent," the draft revised FONSI says. Relevant documents are available on InsideEPA. com. Seepage 2 for details.

At issue is the treatment of secondary waste from the neutralization of more than 1,200 tons of VX agent, which are currently stored at Newport. The Army originally planned to treat the effluent on site, but after the Sept.11 terrorist attacks, the Army moved to explore off-site treatment options. Local officials in Ohio last year thwarted a plan to send the hydrolysate for treatment at a Dayton, OH, facility, in large part because of vocal opposition from residents near the treatment plant (Defense Environment Alert, Oct. 21, 2003, p5).

Now the Army is considering sending the hydrolysate for treatment at the New Jersey DuPont facility, the world's largest commercial and industrial wastewater treatment plant.
Late last year, the Army announced it is changing the formula for VX neutralization, in order to eliminate problems in meeting agent destruction levels. But the formula change - starting with only 8 percent VX by weight instead of 33 percent - will also increase the amount of secondary waste produced by the neutralization facility and could prolong the weapons disposal process (Defense Environment Alert, Dec. 30, 2003, p8).

The 33 percent formula would produce approximately 900,000 gallons of effluent, while an 8 percent formula would create about 3.6 million gallons of hydrolysate, according to the transportation analysis accompanying the draft revised FONSI. Assuming that each tanker truck load required for transporting the liquid effluent to an off-site TSDF will contain 4,000 gallons, the resulting waste from the 33 percent formula would require 225 trips, while the effluent from the 8 percent formula would require 900 trips, the analysis says.

Effluent from the 33 percent processing would be considered a corrosive and ignitable waste under the Resource Conservation & Recovery Act. But the 8 percent hydrolysate would have a lower organic content and thus only be considered corrosive, the analysis says.

The analysis considered two routes, both on Interstate or other major highways. The first route is shorter, but the second route goes through less populated areas.

The public connnent period on the draft revised FONSI ends in the middle of this month.
