Managing Uncertainties during Hydropower Dam Removals
Peter E. Haug, Ayres Associates Inc.
3:30 p.m. - 5:30 p.m.
Mine operators and power plant owners have used a variety of methods to assess
and rank the risk associated with operating impoundments for tailings and
combustion ash. Company management frequently employ tools ranging from
audits to risk screenings, performed within their regulatory compliance,
environmental, dam safety or risk management departments, to assess potential
exposure to release from impoundments as well as environmental impact. Are the
risks adequately understood, and the pathways for potential release of tailings or
combustion ash sufficiently recognized to support risk assessment? Are
procedures for screening and analyzing risk capable of providing guidance in risk
management programs? As impoundments are closed either because of service
life exhaustion or regulatory decree, can risk assessment continue to be of
service?

encountered, and practicing engineers working to maintain or close these
structures.

Concurrent Workshop 2: Paths to Success —

8:00 a.m. - 12:00 noon
Concurrent Workshop 4: Current Uses of
Roller-Compacted Concrete in Dams
Organized by the USSD Committee on Environment and Sustainability
Organized by the USSD Committee on Concrete Dams
Moderators — Blaine Dwyer, HDR; and Denise Bunte-Bisnette, Santee Cooper
Moderator — Michael F. Rogers, MWH
Throughout the U.S., public agencies and utilities are endeavoring to develop
additional water storage as well as better use existing water storage to improve
water supply reliability, enhance supply diversification and meet future demands.
These processes are bringing forth important new strategies for addressing
complex federal, state and local regulatory requirements, environmental needs,
and diverse stakeholder and public interests. Owners are facing daunting
challenges meeting the requirements of the laws and policies administered by
resource and regulatory agencies that often result in lengthy and costly planning
and permitting processes. Using examples from across the country, the speakers
and panelists will compare and contrast key elements for successful project
development including strategic engagement of stakeholders and the general
public including impact avoidance and minimization, up-front mitigation
implementation, adaptive management approaches, and alternative dispute
resolution mechanisms to demonstrate how careful planning supports successful
permitting.
The USSD Committee on Concrete Dams is currently engaged in a collaborative
effort with ICOLD to publish an update to ICOLD Bulletin 126 – Roller
Compacted Concrete for Dams. USSD will be leading the technical updates to
three chapters in the RCC Bulletin: Construction; Performance; and Appurtenant
Uses. This Workshop will present a general discussion of Bulletin 126 as well as
the proposed updates. The Committee is soliciting USSD members and others
with interest and experience in RCC to attend this Workshop and discuss the
proposed updates. It is hoped that the Workshop leaders and participants will
identify key aspects of these RCC design features that could be included in the
updated Bulletin. The current version of Bulletin 126 can be downloaded from
the ICOLD website.

Concurrent Workshop 5: Underwater
Investigation and Construction
Concurrent Workshop 3: Dams on Karstic
Moderator — Frank Immel, Global Diving & Salvage, Inc.
Organized by the USSD Committee on Foundations
This Workshop will educate participants about what can and cannot be done
underwater. The idea for this Workshop developed from a conversation about the
kinds of work the commercial diving/marine construction community is doing.
Members of the engineering community are often surprised to learn that most
work that can be performed on the surface can also be performed underwater. It
may cost a bit more and take a bit longer, but it can be done. A relatively recent
development is the ability to ‘see’ underwater using remote sensing technology
to collect and present detailed information about an existing structure. This
Workshop will use presentations and case studies to discuss:
Moderator — Troy O’Neal, Corps of Engineers
Numerous dams in the U.S. have been constructed on sites underlain by bedrock
prone to varying degrees of solutioning. The solutioning process is normally
more pronounced in areas with increased water flow such as along joints and
bedding planes. Initially, insoluble material in the form of residual soil remains.
Over time the soft soil is eroded, and a network of open and soil filled voids are
left in the rock. The term “karst” is typically used to characterize rock that is
known to have solution features.
1) Setting the stage: why underwater work may be needed, as well as potential
challenges, including financial and environmental obstacles.
This Workshop will explain how karst is formed, (both in carbonate and
evaporite rocks) and where it is found in the U.S. Attendees will be given an
overview of poor performance of dams founded on karstic rock, investigative
techniques and alternatives measures for these foundation conditions.
Additionally, several case histories will be presented and will be followed by a
panel discussion.
2) Defining what you have: recent advances in technology that make it possible
to “take a “picture” of a structure and its components.
3) The broad range of work that can be performed underwater.
