Provided at Bob’s request this morning:
FY20 I4 Milestones for West Lake Landfill
EPA entered into two separate Interagency Agreements with the US Army Corps of Engineers:
one to obtain their assistance with design and construction oversight for the subsurface barrier
intended to separate the subsurface oxidation event in OU2 from the radiologically impacted
material in OU I; and the other to provide independent technical reviews of the deliverables the
PRPs will generate under the Supplemental SFS. USACE provided EPA its evaluation of the
engineering considerations with the three potential barrier alignments that have been considered
to date. EPA continued to coordinate with the US Geological Survey under another IA as they
prepared a comprehensive evaluation of groundwater hydrology and background concentrations
and sources of radionuclides at the site. EPA issued a Pre-Construction Order to the PRPs that
directed them to begin preparing the site for the eventual construction of the subsurface barrier
and provide other technical documents on bird mitigation and air monitoring that will support
this construction. EPA installed a network of five off-site air monitor stations in the surrounding
community to begin collecting a background baseline data set to help evaluate air sampling data
to be collected during the eventual construction of the subsurface barrier. EPA’s Office of
Research and Development evaluated the PRP’s report on the possible effects the OU2
subsurface oxidation event might have on the RIM in OUI should the SSE migrate into OUI in
the future. ORD has also been tracking the monthly reports on the SSE extent and gas and
temperature data provided by the PRPs to the Missouri DNR to provide an independent
assessment of SSE behavior. EPA responded to community concerns about possible radiological
contamination at the Bridgeton Municipal Athletic Complex and conducted a thorough
investigation of the area which determined that there was no radiological contamination there.
EPA has coordinated extensively with the community through attendance of the monthly
Community Advisory Group meetings and issuance of weekly “West Lake Update” newsletters.

Principles and integrity are expensive, but they are among the very few things worth having.
