2012 IOAP Modification

On June 19, 2014, MSD received approval of the 2012 IOAP Modification from the Kentucky Department for Environmental Protection and the United States Environmental Protection Agency Region 4. The project and program modifications proposed within this submittal resulted from MSD’s adaptive management approach to overflow abatement implementation – permitting adjustments resulting from ongoing system monitoring, hydraulic modeling and best professional judgement. The modifications will result in a higher level of overflow control to be completed faster than originally proposed for approximately the same overall budget.

The 2012 IOAP Modification Volume 1, 2 and 3 submitted for approval in May 2014, can be found in the library. Additional interim submittals that led to this approval will soon be posted for public access as well.
