Introduced by: Kathy J. Byron | all patrons    ...    notes | add to my profiles | history

SUMMARY AS PASSED:

Update of the Probable Maximum Precipitation level. Directs the Department of Conservation and Recreation to utilize a storm-based approach to calculate the Probable Maximum Precipitation (PMP) for various locations in or affecting Virginia. The methodology for a storm-based approach shall be completed by December 1, 2015. Owners of impounding structures with spillway design inadequacies who maintain coverage under the conditional certificate are not required to rehabilitate the spillway until the PMP analysis is completed and reviewed by the Virginia Soil and Water Conservation Board. The bill requires the Board to consider the results of the PMP analysis in its decision of whether to authorize replacement of the current PMP values. The Department of Conservation and Recreation is authorized to expend up to $500,000 in unobligated balances from two agency funds to finance the analysis. The bill contains an emergency clause. This bill is identical to SB 582.

SUMMARY AS INTRODUCED:

Update of the Probable Maximum Precipitation level. Directs the Department of Conservation and Recreation to utilize a storm-based approach in order to derive the Probable Maximum Precipitation (PMP) level for locations in the Commonwealth. By updating the PMP, it is anticipated that dam owners will have significant cost savings in spillway construction and remediation efforts. The bill contains a contingency clause indicating that it will not take effect unless funding is available to carry out the purpose of the legislation. The bill also allows owners of impoundment structures regulated under Virginia's Impounding Structure Regulations (4VAC50-20) to apply for a provisional license from the Department of Conservation and Recreation that shall allow impoundment structures to continue to function with no upgrades until the storm-based analysis has been completed.
