SUPPLEMENTARY INFORMATION: The FR/SEIS includes a water supply storage
reallocation study evaluating a March 30, 2018, request by the State of
Georgia and the Cobb County-Marietta Water Authority for increased
water supply use at Allatoona Lake; a State of Georgia recommended
storage accounting method; updated operating criteria and guidelines
for managing the water storage and release actions of Federal water
managers; Alabama Power Company's (APC) proposed raising of winter pool
levels for recreation and lowering the upper limit of the induced
surcharge operational pools at Weiss Dam and Lake (Reservoir); and
Logan Martin Dam and Lake (Reservoir). USACE will also update the Water
Control Manuals (WCMs) for Allatoona Lake and APC's Weiss and Logan
Martin Reservoirs, and the Alabama-Coosa-Tallapoosa (ACT) River Basin
Master Manual.
A final array of alternatives was considered in detail during the
plan formulation process. USACE identified Alternative 11 as the
Recommended Plan in the FR/SEIS; however, Alternative 12 was chosen as
the Selected Plan and will be implemented. Alternative 11 would have
reallocated 33,872 acre-feet (ac-ft) of storage in Allatoona Lake
(11,670 ac-ft from flood storage and 22,202 ac-ft from conservation
storage) and would have utilized the USACE storage accounting method.
The USACE storage accounting method charges all water supply
withdrawals to the respective water supply account and credits all
inflows, including return flows directly to Allatoona Lake or additive
flows released from Hickory Log Creek Reservoir, to all accounts
according to their proportion of project yield. Alternative 11 would
have also modified flood control storage to the APC projects Weiss Lake
and Logan Martin Lake. The Selected Plan (Alternative 12) would
reallocate 14,159 ac-ft from conservation storage at Allatoona Lake for
water supply storage and utilizes the Georgia preferred storage
accounting method in which 100 percent of return flows from Cobb
County's water treatment facilities at Allatoona Lake and releases from
the upstream Hickory Log Creek Reservoir would be credited to water
supply storage accounts. The Selected Plan also includes modified flood
control storage to the APC projects' Weiss and Logan Martin Reservoirs
(unchanged from Alternative 11).
A summary of environmental consequences for the final array of
alternatives is provided in the FR/SEIS. Three of the alternatives (in
addition to the no action alternative) were selected for detailed
analysis of impacts in accordance with the National Environmental
Policy Act; they are Alternative 11 (the Recommended Plan), Alternative
10, and Alternative 3. The other alternatives are variations of these
three alternatives, and they would involve similar impacts as one of
these three alternatives. The Selected Plan (Alternative 12) is similar
to Alternative 10, except that Alternative 12 includes the use of the
Georgia preferred storage accounting method. The anticipated
environmental consequences of the Selected Plan (Alternative 12) are
not significantly different from those anticipated for Alternatives 10
or 11.
The ROD documents why the USACE has chosen to implement Alternative
12 instead of Alternative 11, as described in the FR/SEIS.
