Spring Valley Partners Straying Off US Army Corps Reservation

Paul Chrowstowsi, Ph.D. QEP

P. Chrostowski mentioned that AU feels that in the event of an arsenic trichloride release within the ECS, substantial arsenic trichloride concentrations may remain airborne ... AU recommended specific air monitoring enhancements and an additional air monitoring system to address this concern.

Chrostowski described the AU administration’s position on future work conducted at the Pit 3 property. A comprehensive plan should be developed to address all possible AUES-related property findings, including removal of the house, ancillary excavation underneath the house footprint, and specific recommendations for the next high-probability investigation phase. Removal of the entire structure appears to be the only acceptable course of action, due to uncertainties about the amount of AUES-related items and contamination remaining on the property.

Veolia Environmental Services (Port Arthur)

EPA expressed the need for further discussion and analysis of waste disposal alternatives. Although AUES-related waste is currently shipped to a licensed facility in Port Arthur, Texas, the surrounding area is an environmental justice showcase community where residents and EPA have expressed concerns about waste disposal and overall pollution. Future planning should include a public meeting in Port Arthur with significant input from community members and stakeholders.

Dr. Peter deFur

Peter deFur inquired about EPA’s progress in obtaining information from the builder of the Pit 3 property. EPA explained that a letter was sent to pursue information on AUES-related discoveries during house construction. The builder’s lawyer responded in February 2010 and claimed business confidentiality based on attorney-client privileges ... DDOE replied that DC Councilmember Mary Cheh suggested issuing a subpoena.
