Asset Renewal Program (ARP)

Starting in 2009, the SLSDC began its Asset Renewal Program (ARP) for its navigation infrastructure and associated facilities and equipment.  The projects and equipment included in the ARP address various needs for the two U.S. Seaway locks, the Seaway International Bridge, maintenance dredging, operational systems, and Corporation facilities and equipment in Massena, N.Y.  None of the ARP investments result in increases to the authorized depth or width of the navigation channel or to the size of the two locks.

The SLSDC obligated $109 million on 48 separate projects during the ARP’s first seven years (FYs 2009-2015). These projects included maintenance dredging in the U.S. portion of the Seaway navigation channel, lock culvert valve machinery upgrade to hydraulic operation, structural rehabilitation and corrosion prevention work on the Seaway International Bridge, gatelifter upgrades, and miter gate rehabilitation, as well as various other structural and equipment repairs and/or replacement.

For the FY 2017-2021 period, the Seaway ARP/Capital Investment Plan (CIP) includes 60 separate ARP projects and equipment estimated at $98.3 million with total funding for each year of the plan constrained to funding targets for those years as approved by the Secretary and subject to annual appropriations. Projects and estimates included in the current ARP five-year plan are detailed on pages 10-23 and 26-27.  It is important to note that dollar amounts for ARP projects are “project feasibility” estimates that can vary by an industry-recognized standard of 20-30 percent.  Project estimates and schedules may fluctuate at various points in the lifespan of the ARP and will be revised as needed and on a continuing basis throughout the length of the ARP.

The SLSDC’s ARP is resulting in not only modernized infrastructure and new equipment to ensure the long-term reliability of the St. Lawrence Seaway, but it is also having a positive and significant impact on the Upstate New York economy.  In fact, approximately $60 million of ARP funds obligated during the program’s first seven years were awarded within the Upstate New York region.  In addition to these contracts, the ARP generates, on average, $2 million in additional economic benefits to the region (local permanent and temporary hires, local spending on supplies and equipment, lodging, meals, etc.) each year.
