Part 3702 - Construction and Maintenance of Dams
The Division issues permits for the construction, operation and maintenance of new dams and the modification, operation and maintenance of existing dams. Dams are classified by the Division based on hazard potential into one of three hazard classifications. All dams in the two higher classifications are required to have a permit under these rules. Dams in the lower hazard classification require a permit for construction or modification if they meet certain size criteria.
Permits are also required for removing dams and transferring ownership of dams. Anyone proposing to construct a new dam is encouraged to submit a preliminary design report to the Division for a provisional hazard classification.
