Monday, August 17, 2009 - Noon - DOUBLETREE HOTEL, Second Floor (
"Progress Report on the
A new navigation lock is being built by the U.S. Army Corps
of Engineers just below the Chickamauga Dam on the Tennessee River about seven
miles upstream from Chattanooga. The new lock was needed because the existing
lock developed structural deficiencies resulting from physical expansion of its
concrete structure. The phenomenon of concrete growth was observed soon
after the locks initial operation in 1940. Despite costly aggressive
maintenance procedures, the continued concrete expansion threatened the
structural integrity of the lock and limited its life. Engineering
reliability studies suggested that the probability of an event with
unacceptable and possibly catastrophic results would increase significantly
after 2010. Construction of the new lock began in 2004. It is 110’ wide
by 600’ long – almost dwarfing the existing 60’ x 360 dam
that is located along side of it.
Wayne Huddleston will describe the concrete growth issues at
the existing lock, as well as the status of the new lock construction. He
will discuss the project schedule, budget, and the ongoing cofferdam
contract. Mr. Huddleston is with the Nashville District, U.S. Army Corps
of Engineers where he is the Manager for Chickamauga Lock Replacement Project.
FUTURE MEETINGS________________________

MEETING_______________________
Rob Ellis, Geologist and Greenhouse
Gas Program Manager at Advanced Waste Management Systems (AWMS) said his
company was founded in 1985 to verify, as a third party, an
organization’s greenhouse gas emissions. The six greenhouse gases
covered are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O),
hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride
(SF6). Accurate accounting of emissions is used to project changes in the
concentration of GHGs in the atmosphere and to determine emission contributions
from specific sources. Conflict of interest is managed on a per-program
basis.
Over the past few years, states and
regions have established policies to qualify and measure GHGs. Rob
discussed The Climate Registry, which compiles information on annual emissions
from each member of the registry. Participation in The Climate Registry is
voluntary, and The Registry has members throughout
Rob also mentioned the
Waxman-Markley comprehensive energy bill, which includes a cap-and-trade
greenhouse gas reduction plan designed to reduce economy-wide greenhouse gas
emissions 17 percent by 2020. Other provisions include new renewable
requirements for utilities, studies and incentives regarding new carbon capture
and sequestration technologies, energy efficiency incentives for homes and
buildings, and grants for green jobs, among other things.
Rob said that The Environmental Protection Agency draft rule
mandates a national inventory of greenhouse gas emissions in excess of 25,000
tons/year.
