Dam Safety & Security

Disaster resilience exercises performed in Washington State

Dozens of participants recently completed a series of exercises designed to develop a strategy to improve disaster resilience and preparedness in the Tri-Cities area of Washington State (Kennewick, Pasco, and Richland). Participants expect that this exercise-based approach can serve as an effective vehicle for developing integrated disaster resilience strategies for other regions in the U.S., says the U.S. Department of Homeland Security's (DHS).

The exercise is part of the 2009 Dams Sector Exercise Series – Columbia River Basin (DSES-09). Participants include the Pacific Northwest Economic Region, DHS, U.S. Army Corps of Engineers, and regional stakeholders.

DSES-09 efforts are based on a severe rain-on-snow scenario that affects a large portion of the Columbia River Basin and leads to significant flooding along the river. The flooding event leads to overtopping and subsequent breaching of levees in the Tri-Cities area. This poses emergency management and public safety challenges and affects several other critical infrastructure sectors, such as transportation and energy, DHS says.

The DSES-09 effort is organized into five tracks: modeling and mapping, pre-disaster operational response, state and local preparedness and emergency response, long-term restoration and economic resilience, and integrated regional strategy. Each track was conducted separately. The events follow the Homeland Security Exercise and Evaluation Program, maintained by DHS. This is a performance-based exercise program that provides a standardized methodology and terminology for exercise design, development, conduct, evaluation, and improvement planning. The events include a concept and objectives meeting, a pre-exercise seminar, a tabletop exercise, and a follow-up after-action/strategy workshop.

In July 2009, participants held a state and local emergency preparedness/emergency response tabletop exercise in Pasco, Wash. More than 80 people representing 25 federal, state, and local government agencies, as well as the private sector, participated in the tabletop exercise. This exercise identified disaster management challenges in many areas, including emergency management organizational structure and decision-making process, public information, energy effects, transportation effects, and infrastructure interdependency-related effects on essential services.

In September 2009, participants held a long-term restoration/economic resilience tabletop exercise in Pasco. A total of 60 participants, including representatives of DHS, the Federal Emergency Management Agency, the Corps, and other agencies, discussed long-term effects from a flood event in the Tri-Cities area. Participants also discussed actions to recover and restore infrastructure and essential services; transitioning from incident response to long-term regional restoration; federal, state, and private sector assistance; and potential prevention and mitigation measures.

The overall DSES-09 effort will culminate with the development of a regional disaster resilience and preparedness strategy for the Columbia River Basin.

Awards of merit

This year's National Award of Merit was presented to the Federal Energy Regulatory Commission (FERC) Division of Dam Safety. In presenting the award, ASDSO cited FERC's mission as a regulatory body and the high level of excellence exhibited by the dam safety team at FERC headquarters and FERC regional offices in carrying out this national regulatory program. In addition to honoring Dan Mahoney, director of the Division of Dam Safety, ASDSO recognized Frank Calcagno, senior engineering geologist; Bill Allerton, deputy director; and regional representatives Charles Wagner (Atlanta), Peggy Harding (Chicago), Peter Valeri (New York), Patrick Regan (Portland), and Ron Adhya (San Francisco).

Several regional awards of merit also were presented at the banquet.

The Ute Water Conservancy District in Grand Junction, Colo., received the West Region Award of Merit. ASDSO cited the conservancy district's proactive maintenance of its dams to the highest standards and the completion of several dam safety projects in 2008 and 2009.

The Mississippi Soil and Water Conservation Commission in Jackson, Miss., received the Southwest Region Award of Merit for its creation of the Mississippi Watershed Repair and Rehabilitation Cost Share. This state program provides funds for repairing and rehabilitating watershed dams and for matching funding from the U.S. Department of Agriculture's Natural Resources Conservation Service.

Pennsylvania American Water in Mechanicsburg, Pa., received the Northeast Region Award of Merit. When the company assumed ownership of 64 dams and reservoirs that supply water to more than 2 million customers, 29 of these dams were classified as high hazard. Pennsylvania American Water immediately conducted detailed surveys of all the dams, including risk assessments and rehabilitation prioritizations of the high-hazard dams. The company has embarked on an aggressive program to upgrade its high-hazard dams.

Mia P. Kannik, P.E., with the Ohio Department of Natural Resources in Columbus received the Midwest Region Award of Merit. ASDSO's Journal of Dam Safety annually publishes an article from each of the four regions. Kannik has coordinated the effort of promoting and writing technical articles from the Midwest region since the program's inception.

Rehabilitation project of the year

ASDSO selected Lake Burnt Mills Dam, a high-hazard earth embankment dam built in 1942, as its 2009 rehabilitation project of the year. The city of Norfolk, Va., owns the dam, which impounds 10.300 acre-feet of water for Norfolk and adjacent communities. Hydrologic/hydraulic, geotechnical, and structural investigations and analyses identified several dam safety deficiencies. The most urgent deficiencies included the inability to safely pass the probable maximum flood, inadequate safety factor of the intake tower and training walls, severe deterioration of concrete below the waterline, and improper design for the spillway crest.

Remedial measures undertaken starting in 2006 included spillway and embankment modifications and low-level outlet replacement. The design and construction of these remedial measures successfully addressed the dam deficiencies and the requirement to maintain the use of the reservoir and to maintain dam safety during construction.

Special recognition

This year, the ASDSO board of directors unanimously agreed to formally recognize the work of the National Committee on Levee Safety. This committee is mandated by the National Levee Safety Act and led by the U.S. Army Corps of Engineers. In late 2008 and early 2009, the committee created the 104-page Report to Congress on Recommendations for a National Levee Safety Program.

Other awards

Darrel Temple, a national and international authority on the hydraulics of vegetated open channels, spillways, and earthen embankments, was awarded the Terry L. Hampton Medal. ASDSO's Affiliate Member Advisory Committee established this medal in 2007 to recognize outstanding achievements in the field of hydrology and hydraulics.

Finally, the President's Award was given to Michele Lemieux, P.E. This award is given to an individual or group who has assisted the president during his or her term in office. Lemieux, a civil engineer with the Montana Department of Natural Resources and Conservation, serves on ASDSO's Conference Planning Committee, Technical Training Committee, and Editorial Committee of the Journal of Dam Safety.

Corps to perform seismic mitigation work at Bonneville

The U.S. Army Corps of Engineers is preparing to perform seismic mitigation work on the Ambursen Section of 1,076.6-MW Bonneville Lock and Dam on the Columbia River in Oregon. This work is needed to reduce the risk of failure of this section of the dam during design seismic loading.

The work to be performed entails filling the north wall of the old navigation lock, referred to as the Ambursen Section, with concrete. Monoliths 20-25 of the old lock north wall are hollow sections. They are to be filled with concrete to form new gravity dam sections.

The work, which is valued at $5 million to $10 million, involves foundation preparation, concrete and gravel placement, control and treatment of seepage water, anchoring, and grouting.
