U.S. EPA Seeks Comments
On Proposed Sewer Plan
Lower Mill Creek Sewer Overflow Proposed Remedy
Hamilton County and Cincinnati, Ohio	January 2013
The U.S. Environmental Protection Agency is seeking public comments on
a proposed plan to reduce sewer overflows to Lower Mill Creek. Hamilton
County commissioners and the city of Cincinnati submitted a document in
December called the Revised Original Lower Mill Creek Partial Remedy
to federal, state and local environmental regulators. The proposal lists a
number of measures to reduce the amount of stormwater that currently
enters the Lower Mill Creek sewer system. The proposed plan includes
innovative "green" infrastructure techniques to reduce sewer flows without
the need for expensive water control structures. Supporters say the plan
would substantially reduce raw sewage discharges from locations in the
sewer system called "combined sewer overflows" or CSOs.
U.S. EPA, Ohio EPA and the Ohio River Valley Water Sanitation
Commission (ORSANCO) will consider the revised plan. U.S. EPA
invites public comments on the proposal. A 30-day comment period will
open Jan. 10 and run to Feb. 10. A decision on the proposed alternative
sewer plan will likely be made by regulators this spring. See the left-hand
box on ways you can participate in the decision-making process.
Legal history
The revised Lower Mill Creek water plan was originally prompted by two
court orders to reduce sewer overflows in the area served by the
Metropolitan Sewer District of Greater Cincinnati (MSDGC). In 2010, the
U.S. District Court entered an amendment to those orders. The amendment
requires Hamilton County and the city of Cincinnati to implement what
was originally a $3.3 billion remedy that was referred to as the "Wet
Weather Improvement Program" or WWIP. The WWIP will address
billions of gallons of untreated overflows discharging to local water
bodies and the Ohio River each year.
In the legal amendment, U.S. EPA agreed to a phased-in schedule because
of the high cost of the cleanup measures and the financial burden in the
form of higher water rates it will put on area businesses and residents. The
amendments also allowed the county and city to propose a money-saving
alternative approach to deal with overflows in the Lower Mill Creek
portion of the sewer district's service area. This alternative approach is
now being released for public comment. Regulators will approve the plan
if it meets the requirements of the original WWIP.
Revised plan
The alternative plan now under consideration was formulated during 2010-
2012 when the Metropolitan Sewer District updated its CSO system model
and conducted extensive engineering and cost analyses.

Beginning in the summer of 2012, MSDGC held
weekly phone calls with staff from U.S. EPA, Ohio
EPA, and ORSANCO. Public outreach and public
participation efforts were also carried out by MSDGC
and Hamilton County to solicit public input on the
potential alternative remedy for Lower Mill Creek.
In December 2012, MSDGC, on behalf of the county
and the city, submitted the revised plan to U.S. EPA,
Ohio EPA and ORSANCO.
The revised plan proposes to employ a strategic
separation approach implemented on a watershed-by-
watershed basis. In selected watersheds, stormwater
would be removed from the wastewater collection
system through a combination of green infrastructure
and conventional methods. Green infrastructure can
involve the use of greenways, rain gardens, swales,
native landscaping and porous pavement to reduce
runoff and flooding and improve water quality.
Around one stream called Lick Run, a new green
corridor is proposed in the alternative plan that would
expose a long-buried stream and allow for overland
flow of stormwater. The Lick Run green corridor could
potentially provide valuable community benefits to
distressed community areas, in addition to serving as a
significant component of the wet weather control
program.
One requirement of the original wet weather
improvement program was for Hamilton County and
Cincinnati to construct a deep tunnel structure to store
and channel excess stormwater. Officials hope the
proposed revised plan will eliminate the need for this
very expensive tunnel project.
