municipalauthorities.org | 61 Conclusion: The Paxton Creek Cooperative collaboration allowed each participant to achieve their individual municipal PRP sediment load reduction requirements while allowing BMP’s to be implemented in locations that best address the source of the sedimentation occurring throughout the impaired watershed. This approach eliminates the need for municipalities to install BMPs in locations that may not be sources of pollution to satisfy theoretically prescribed regulatory load reduction goals. Not only is the integrated approach the most cost-effective approach for the municipalities involved to meet their permit requirements, but it’s also the most beneficial to the water quality of the local streams, as well as the Susquehanna River and Chesapeake Bay. The total original cost estimate was $12,795,000 dollars. With this collaboration, the total cost to the Cooperative was approximately $4,000,000 dollars, resulting in the reduction of anticipated cost by more than 70%. Future Collaborations: The Paxton Creek Coopartive will continue to collaborate to achieve future MS4 Permit requirements. The PADEP has published new draft criteria that changes focus to the reduction of runoff volume that will require municipalities to prepare a Volume Management Plan (VMP) and a final Volume Management Objective (VMO) to achieve 2% volume reductions per year over a 50-year period. The VMP and VMO are determined by using the PADEP Maximum Extent Practicable (MEP) Calculator. Projects may include Stream Restoration with Floodplain Restoration components, Infiltration/ET, Rate/Flood Control Retrofits and other Volume Management SCMs. If this new criterion is adopted, a cooperative approach will be needed to select the most cost-effective approach for the municipalities to meet these new requirements.
