A. The Board shall develop a general permit for the regulation of low hazard potential impounding structures in accordance with § 10.1-605.
e. A certification from the owner that the impounding structure (i) is classified as low hazard pursuant to a determination by the Department or the owner’s professional engineer in accordance with § 10.1-604.1; (ii) is, to the best of his knowledge, properly and safely constructed and currently has no observable deficiencies; and (iii) shall be maintained and operated in accordance with the provisions of the general permit.
2. A spillway design flood requirement of the 100-year flood. When appropriate, the spillway design flood requirement may be reduced to the 50-year flood in accordance with an incremental damage analysis.
4. An annual inspection of the impounding structure by the owner. No inspection of the impounding structure by a licensed professional engineer shall be required if the owner certifies at the time of general permit coverage renewal that conditions at the impounding structure and downstream are unchanged.
6. A six-year term of coverage under the general permit after which time the owner shall reapply for coverage by filing a new registration statement. The Board may, by regulation, establish a fee for the processing of registration statements.
C. The owner shall notify the Department immediately of any change in circumstances that would cause the impounding structure to no longer qualify for coverage under the general permit. In the event of a failure or an imminent failure at the impounding structure, the owner shall immediately notify the local emergency services coordinator, the Department of Emergency Management, and the Department. The Department shall take actions in accordance with § 10.1-608 or 10.1-609, depending on the degree of hazard and the imminence of failure caused by the unsafe condition.
E. In order to qualify for the provisions of § 10.1-606.3, a dam owner eligible for a general permit shall file a dam break inundation map with the Department and with the offices with plat and plan approval authority or zoning responsibilities as designated by the locality for each locality in which the dam break inundation zone resides in accordance with § 10.1-606.2.
F. If the failure of a low hazard potential impounding structure is not expected to cause loss of human life or economic damage to any property except property owned by the owner, the owner may follow the special criteria established for certain low hazard impounding structures in the Impounding Structure Regulations (4 VAC 50-20) in lieu of coverage under the general permit.
