Change in California Cleanup Goals
State of California Office
of Environmental Health Hazard Assessment (OEHHA) has finalized the new
California Human Health Screening Level (CHHSL) for lead. The revised screening levels are 80 mg/kg for
residential land use, and 320 mg/kg for commercial-industrial land use. The revised CHHSL also immediately supercede
previous Environmental Screening Levels (ESLs) of 260 mg/kg for residential
land use and 750 mg/kg for commercial-industrial land use. This change can dramatically impact the cost
of cleanup at sites with lead contamination in soil.

CEO's Message
Dear Clients, Colleagues and
Friends:
2009 has been a good year so far,
and we appreciate the opportunity to help with the many challenging projects
that you have brought to us. Earlier
this year we added Dr. Adam Love to our team.
Adam brings many talents and experiences that complement the JWI team,
as well as providing new areas of technical expertise for our growth. We also added Kimberly Lake
to our team, and she brings her own extensive training and experience. Both are important additions to the JWI
team. Links to bios for each are in this
newsletter. Please take a moment
to review their bios and get to know them.
In August we moved into a larger
office space, just across the street from our former offices here in Lafayette. We plan on staying in this location for at least
five years, as there are enough additional offices to handle our plan for
moderate growth. Please feel free to
come by whenever you may be in our area.
If you happen to be in the City (which is what locals call San Francisco), you can
travel here easily by the rapid transit system.
This newsletter contains several
articles that highlight some of the key issues we are tracking in the
environmental world. There is an update
on the overall status of the Portland Harbor Superfund Site and preview to upcoming
issues. We provide a summary of the TVA
fly ash release from December 2008 that may lead to potential changes in use,
storage, and remediation of heavy metal containing sludge. Lastly, we provide
updates on the addition of sites to the NPL, and USEPA Superfund spending.
We hope you enjoy and benefit from
this newsletter. It is part of our
commitment to provide you with value that extends beyond the specific projects
we are working on with you. Thanks again
for the opportunity to help.
Warm regards,
Peter

Portland Harbor Superfund Site Update
By John Elliott, P.E.
This article provides a
brief update on the key project activities related to the Portland Harbor
Superfund (PHSF) Site. The PHSF Site is an 11.6-mile reach of the Lower Willamette
River between downtown Portland and the confluence with the Columbia
River. The remedial
investigation of the site is getting close to completion. After approximately 8 years, the draft
remedial investigation (RI) and baseline risk assessment (BLRA) reports are
expected to be submitted to the EPA before the end of 2009 and the feasibility
study (FS) is expected to be completed in 2010.
Tens of millions of dollars have been incurred to complete the field
work for the RI and BLRA. Additional
costs will be incurred to prepare the RI/BLRA report and FS. It was initially expected that a proposed
remedial plan and Record of Decision (ROD) would be issued in 2012, but with
the project's history of delays due to the inherent complexity of the Site, the
ROD may be even
further off.

Environmental Release of Coal Fly Ash Sludge, Tennessee Valley Authority,
Kingston Fossil Plant
By Paul Nuti, P.E., LEED AP
At the end of 2008, the Tennessee
Valley Authority (TVA) experienced an environmental release of historic
proportion. Over a billion gallons of
waste sludge generated at a coal-fueled power plant was discharged onto nearby
land and into nearby waterways, impacting hundreds of acres down stream. This article provides a summary of the event,
subsequent health and environmental concerns, and resulting lawsuits.

CERCLA Update - NPL Sites &
Superfund Spending
By Alborz Wozniak, P.E.
Since 2008, the US
Environmental Protection Agency (USEPA) has added 17 new hazardous waste sites
to the National Priorities List (NPL) and proposed adding 21 other sites to the
list. To date, there have been 1,587
sites listed on the NPL. The USEPA uses
a variety of mechanisms to place a site on the NPL. These mechanisms may include the ranking
system established by EPA's Hazard Ranking System, designation by states or
territories of top-priority sites, or based on an assessment of whether the
site poses a significant health risk to the public.
