Intent To Prepare an Environmental Impact Statement for the Upper
Ohio Navigation Study, PA, in Allegheny and Beaver Counties
AGENCY: Department of the Army, U.S. Army Corps of Engineers, DoD.
ACTION: Notice of intent.
-----------------------------------------------------------------------
SUMMARY: Pursuant to the National Environmental Policy Act (NEPA), the
Pittsburgh District of the U.S. Army Corps of Engineers (Corps) is
seeking public comment on the environmental scope of an upcoming study,
named the ``Upper Ohio Navigation Study, Pennsylvania.'' This study
will consider and evaluate the feasibility of alternatives for
maintaining commercial navigation on the Pennsylvania portion of the
Ohio River, and also consider and evaluate the feasibility of ecosystem
restoration opportunities.
The focus of the upper Ohio River navigation feasibility study is
to develop the best plan for maintaining safe, environmentally
sustainable, and reliable navigation on the upper 40 miles of the Ohio
River in Pennsylvania. Navigation is currently provided through three
old lock and dam facilities--Emsworth, Dashields and Montgomery locks
and dams--dating from the 1920s. The study will consider a 60-year
period from 2010 to 2070. Navigation alternatives will consider
facility operation and maintenance, rehabilitation, and new
construction needs and opportunities.
In order to facilitate early public involvement in the planning
process, the Corps will be conducting two environmental scoping
meetings open to the public in the study area. The public is invited to
attend these meetings to hear an overview of the study, and assist in
the identification of significant issues to be considered during the
study process. (See DATES).
DATES: Public scoping meetings will be held on:
1. October 24, 2006, 7 p.m. to 9 p.m., Monaca, PA.
2. October 25, 2006, 7 p.m. to 9 p.m., Coraopolis, PA.
ADDRESSES: The meeting locations are:
1. Monaca, PA--Community College of Beaver County, Library Resource
Center, Conference Room 103, One Campus Drive, Monaca, PA 15061.
2. Coraopolis, PA--Holiday Inn, 8256 University Boulevard,
Coraopolis, PA 15108.
FOR FURTHER INFORMATION CONTACT: The Corps' point-of-contact for
questions or comments on the study and the environmental impact
statement is Mr. Conrad Weiser, U.S. Army Corps of Engineers,

SUPPLEMENTARY INFORMATION:
1. Authority: The proposed action is being conducted under the
authority of United States Senate, Committee on Public Works resolution
dated May 16, 1955; and United States House of Representatives, Committee
on Public Works and Transportation resolution dated March 11, 1982.
2. Background: a. The Corps is initiating a study to identify and
evaluate feasible alternatives to maintain environmentally sustainable
commercial river navigation on the upper 40 miles of the Ohio River in
Pennsylvania. Existing locks and dams to be considered in this study
are the Emsworth, Dashields, and Montgomery (EDM) locks and dams. The
EDM facilities are the uppermost three of the 19 facilities forming the
Ohio River Navigation System. This system provides navigable depths the
full 981-mile length of the river between its origin at the ``Point''
in Pittsburgh, PA, to its mouth at Cairo, IL.
b. Emsworth is the oldest operating facility of the Ohio River
system. Its locks date from 1921, while its original fixed crest dams
were replaced in 1938 with higher gated structures. Dashields and
Montgomery locks and dams were placed into operation in 1929 and 1936,
respectively. Locks and Dams 52 and 53 near the river's mouth are the
only other pre-World War II facilities on the Ohio River system, and
these are in the process of being replaced by a single facility,
Olmsted Locks and Dam.
c. Emsworth, Dashields, and Montgomery each have two lock chambers,
a main chamber measuring 110' x 600'± and an auxiliary
chamber measuring 56' x 360'. Compared to the 110' x 1,200' main lock
chambers at the modern Ohio River facilities, they are the lowest
capacity locks on the river. They form a bottleneck between the modern
downstream Ohio River navigation structures and the tributary
Monongahela River locks with their 720-foot chambers. The disparity in
capacity is magnified during main chamber closures when all traffic
must use the small 56' x 360' chambers. These small chambers can only
process one barge at a time, necessitating multiple lockages for
typical tows of as many as 15 barges, more or less. This study will
[[Page 57488]]
consider the potential benefits of larger main lock chambers at EDM.
d. Additional concerns at EDM involve the structural integrity of
the aged concrete lock walls. Internal cracks throughout the concrete
lock walls may eventually propagate through entire wall sections and
lead to significant movements of wall sections. A major cause of
cracking is concrete deterioration. Because these three locks and dams
were constructed prior to the advent of air-entrainment in concrete,
the concrete has been particularly susceptible to weathering and
freeze-thaw damage. Another source of concern is that concrete
construction practices of the 1920's and 1930's, including mix-design,
placement, consolidation, curing, and cold/hot weather protection, were
much less stringent compared to the quality control tolerances required
for a similar project constructed today. Still another contributing
factor is the raising of the Emsworth Dams and pool in 1938, which
increased the head between the upper and lower pools and increased
structural loads on the concrete lock walls.
e. Major rehabilitations on the EDM lock and approach walls
undertaken in the 1980s addressed short-term issues, but there remains
a concern about their long-term effectiveness. Prior to these major
rehabilitation efforts, lock wall surfaces were in advanced stages of
deterioration and there were concerns about the stability of various
wall sections. Degraded concrete surfaces were removed, and a 12-inch
overlay of new concrete was provided in an attempt to retard
deterioration rates by preventing water from reaching the interior
concrete. However, despite these efforts, water is apparently still
reaching the interior concrete and causing it to become saturated and
susceptible to additional deterioration.
f. Following years of different attempts at estimating concrete
structural reliability, including the possible development of
analytical models and expert opinion, it was decided that a condition
assessment of these three projects and expert opinion were the
appropriate tools to complete this essential task. In September of 2000
a five-person panel of experts was assembled to estimate the current
and future reliability of the structures on the upper Ohio River. This
panel of experts established probabilities of failures, the potential
consequences for various failure modes and estimated the impacts to the
expected service life of several repair or replacement options for
concrete wall sections.
g. The U.S. Army Corps of Engineers, Great Lakes and Ohio River
Division, is nearing completion of a system-wide study of Ohio river
navigation projects. The study was initiated in 1995 and is referred to
as the Ohio River Mainstem System Study (ORMSS). ORMSS is being
conducted by a team of specialists from the Corps' Louisville,
Huntington, Nashville, and Pittsburgh districts. The product of this
study is a ``System Investment Plan,'' which will be the strategic
``roadmap for reinvestment'' establishing priorities for expenditure of
federal funds on the navigation system and recommending site-specific
feasibility studies.
h. The ORMSS ``System Investment Plan'' identifies the need for new
main locks at the EDM facilities. The Upper Ohio River navigation
feasibility study of EDM is the site-specific feasibility study that
could lead to project authorization in a future Water Resources
Development Act.
i. The ORMSS Report combines plan formulation with a programmatic
environmental impact statement in a main report and a series of
appendices. The ORMSS Environmental Appendix includes environmental
documentation and a system-wide Cumulative Effects Assessment (CEA).
The CEA evaluates past environmental impacts, current conditions, and
reasonably foreseeable future actions by the Government and others that
may impact ``Valued Environmental Components'' or resources within and
adjacent to the Ohio River.
j. In accordance with the National Environmental Policy Act (NEPA)
of 1969, the anticipated environmental scope and complexity of the
Upper Ohio River navigation feasibility study in Pennsylvania will
warrant that the NEPA document be a tiered environmental impact
statement (EIS) referencing the ORMSS Programmatic EIS while
anticipating future site-specific, supplemental NEPA documents for each
recommended project component.
3. Public Participation. a. The Corps will conduct public meetings
to gain input from interested agencies, organizations, and the general
public concerning the scope and content of the EIS, alternatives that
should be analyzed, and related issues and impacts to be addressed in
the EIS (see DATES).
b. The Corps invites full public participation to promote open
communication and better decision-making. All persons and organizations
that have an interest in the Upper Ohio Navigation Study, Pennsylvania,
are urged to participate in this NEPA evaluation process.
c. Public comments are welcomed anytime throughout the study
process. Formal opportunities for public and agency participation
include: (1) Public meetings; (2) correspondence, telephone or e-mail
at any time throughout the NEPA process; (3) review and comment on the
draft EIS; and (4) review of the final EIS. Schedules and locations for
formal review periods will be announced through the study's mailing
list and in local news media. Anyone who wishes to be included on the
mailing list for public distribution of meeting announcements and
documents should contact Mr. Conrad Weiser.
4. Schedule: The draft EIS is anticipated to be released for public
review and comment in May 2012. The final report and final EIS are
scheduled to be completed in October 2012.
