2 General Information When and Where: This three-day technical course will be held on Tuesday, Wednesday, and Thursday, November 13-15, 2012 at the Marriott Atlanta Gwinnett Place in Duluth, Georgia. Duluth is located in Gwinnett County, just about 25 miles northeast of metro Atlanta. Registration is limited to the fi rst 60 individuals who apply. Please send in your registration form (or register on-line) early to reserve a spot. Course Overview and Objectives: This seminar provides comprehensive instruction in inspection and evaluation techniques for dams. Although the content has been tailored to focus on NRCS dams emphasizing NRCS policies and requirements, the principles, concepts and procedures taught will be readily adaptable to any organization conducting dam inspections and evaluating their compliance with current design standards. The target audience is NRCS personnel and state dam safety offi cials, however, dam owners, engineers and personnel responsible for the operation and maintenance of dams will fi nd the course relevant. Participants will be familiarized with a variety of dam types and their appurtenances, instructed in the function of typical dam features, and become aware of common dam failure modes and the conditions that can lead to these failure modes. Actual dam failure cases will be presented so that participants will grasp the seriousness and responsibilities associated with performing dam inspections, and know what to look for and be able to identify potential defi ciencies at dams before they become a problem. Public safety, security, and liability will also be discussed along with approaches to responding to dam incidents. Acceptable standards for the condition and operation and maintenance of dams will be presented. The importance of reviewing pertinent records, conducting visual examinations, and monitoring instrumentation will be emphasized. Participants will be introduced to specialized inspection techniques, including confi ned space entry, conduit inspections using remotely operated vehicles (ROVs), and underwater diving inspection. The seminar includes a visit to two local dams to practice inspection techniques, observe a conduit inspection using an ROV, observe the proper operation of water control gates, and collect dam instrumentation readings. The importance of identifying hazard creep as part of the inspection process will also be discussed. There are no specifi c education or experience prerequisites for this course, although some knowledge/experience in dam safety would be benefi cial. Course Manual: Course materials will be produced on DVD. The Workshop DVD will include copies of the presentation slides, plus many helpful references some of which include: FEMA Technical Manual for Dam Owners Impacts of Animals on Earthen Dams FEMA Technical Manual for Dam Owners Impacts of Plants on Earthen Dams FEMA Technical Manual - Conduits Through Embankment Dams, Best Practices for Design, Construction, Problem Identifi cation and Evaluation, Inspection, Maintenance, Renovation, and Repair FEMA Technical Manual Filters for Embankment Dams FEMA P-919 Summary of Existing Guidelines for Hydrologic Safety of Dams Owner and dam safety references Internet URLs for sites where additional information can be found.

Seminar Agenda Day One: All workshop participants will spend the fi rst day in a Safety Evaluations 101 format with learning goals relevant to both engineers and dam owner/operators. The primary goal of the fi rst day is to familiarize participants with a variety of dam types, understand the function of typical dam features, and become aware of common dam failure modes and the conditions that can led to these failure modes. Actual dam failure cases will be presented so that participants will grasp the seriousness and responsibilities associated with performing dam inspections, and know what to look for and be able to identify potential defi ciencies at dams before they become a problem. Public safety, security, and liability will also be discussed along with approaches to responding to dam incidents. Day Two: Participants will focus on the more technical learning goals; on acceptable standards for the condition of dams, and on performing dam inspections. Day two includes techniques for inspecting embankment dams, outlet conduits, drains, relief wells, spillways, instrumentations and concrete dams. The importance of identifying hazard creep as part of the inspection process will also be discussed. Day Three: All participants will attend a fi eld exercise to practice inspection techniques they have learned in the classroom. The exercise will include a video inspection of a conduit, reading instruments, identifying common problems and repairs to gates, valves, conduits and deteriorated concrete, and discussions on methods of addressing animal damage and uncontrolled vegetation.
