Attached is a package containing the newly developed training seminar titled "Plan of Action (POA) for Scour Critical Bridges." This POA training seminar is intended for individuals at the Federal, State and local level who are involved in the planning, development, implementation and maintenance of POAs for bridges determined to be scour critical. This seminar was developed thanks to the joint efforts between the FHWA's National Hydraulics Team (NHT) and the National Highway Institute (NHI) and is designated as FHWA- NHI 135085.

The POA training seminar features three lessons:

• Guidance and Regulations -- Provides among other details, an expanded guidance on management and inspection strategies, and components of a POA Standard Template developed by the NHT.
• Riverine Case Study -- Presents a riverine case study overview of a scour critical bridge.
• Details of POA Standard Template and Riverine Case Study POA -- Presents detailed guidance for completing the POA Standard Template with the information provided in the riverine case study.

Other features of the seminar include expanded guidance for each section of POA Standard Template, a monitoring case study, resources (technical references), and a glossary.

We are providing three copies the seminar on CD-ROMs in the attached package. Please distribute them to the appropriate personnel within your corresponding Federal, State and local agencies who are responsible for the planning, development, implementation and maintenance of POAs, which is an important phase of FHWA National Bridge Scour Evaluation Program to ensure safety of the surface traveling public. The POA training seminar is also available online at no cost at http://fhwa.acrobat.com/n135085seminar.

Also, for your information, the NHT is currently planning to host web-conferences to discuss any questions that your bridge engineer and/or his/her corresponding Federal, State and local counterparts may have concerning the content of this seminar. We will be informing you about these web-conferences as soon as they are scheduled.
