Dear Dam Owners, Engineers and Stakeholders:
The Soil and Water Conservation Board has approved a change affecting the Virginia Administrative Code, Title 4. Conservation And Natural Resources, Agency 50. Virginia Soil And Water Conservation Board, Chapter 20. Impounding Structure Regulations, Part I. General, 4VAC50-20-20. General Provisions. Item F. of this section was updated to include the mandatory use of the Dam Safety Inventory System (DSIS) for all required submissions. Item F. states the following:
F. The owner shall ensure all information required to be submitted under this chapter be provided to the department via the electronic Dam Safety System (DSIS), unless prior approval for an alternative method of submission is granted by the department.
This requirement is effective May 1, 2021 and regulatory language is attached for your convenience. The required use of DSIS furthers the efforts of the department to build and maintain the most up-to-date dam safety data management system possible.
Thank you,
Virginia Department of Conservation and Recreation
Division of Dam Safety and Floodplain Management
