In December, Congress passed a law which will impact the Savannah River Basin. The Water Infrastructure Improvements for the Nation Act, known as the WIIN Act, became public law Dec. 16, 2016. A specific section of this law directly affects the Savannah River just below Augusta.
What the Law Says
The WIIN Act calls for changes to the New Savannah Bluff Lock and Dam (NSBL&D) – changes that would improve an environmental mitigation feature associated with the Savannah Harbor Expansion Project.
The NSBL&D was authorized in the 1930s by the Rivers and Harbors Act to facilitate commercial navigation on the Savannah River. The federal purpose for the structure was to enable commerce by water up to Augusta, and federal tax dollars were appropriated annually to operate and maintain the project.
Commercial navigation ceased in 1979 and over time the integrity of NSBL&D has gradually degraded. Although we have sought funds for rehabilitation, none has been appropriated. As such, the structure has fallen into a state of disrepair and poses a safety hazard to the public.
The WIIN Act acknowledges this and formally deauthorizes the navigation structure. Deauthorization is the official classification when the federal government determines a project no longer has a federal requirement for its original purpose, in this case, commercial navigation.
By deauthorizing NSBL&D, the WIIN Act supersedes a section of law from the Water Resources and Development Act of 2000, which directed the Corps to rehabilitate the structure and turn it over to the care of North Augusta or some other local entity.
Yet the NSBL&D presents another challenge.
By its mere presence it acts as an impassable barrier to endangered Atlantic sturgeon, shortnose sturgeon and other fish, denying access to their historic spawning grounds. In response to this, the SHEP environmental approvals required construction of a fish passage around this federal barrier.
The WIIN Act offers two alternatives made possible through deauthorization. One of the alternatives must be implemented; both eliminate the need for a separate fish passage around the structure. Both alternatives would enable fish to migrate upstream in the river, avoiding the need to dig a separate channel around the NSBL&D.
One alternative calls for repair of the lock wall and modification of the structure to serve two purposes: 1) “to allow safe passage over the structure to historic spawning grounds” of Atlantic and shortnose sturgeon, in a way that enables the structure to 2) “maintain the pool for navigation upstream, water supply, and recreational activities.”
The other alternative calls for removal of the NSBL&D after constructing a water damming structure (or weir) “at an appropriate location” in the river, that would “maintain the pool for water supply and recreational activities” for communities upstream of the current structure. This weir would continue to provide an upstream pool but also permit fish to pass upstream to historic spawning grounds.
Impacts to Communities
The entire section of the WIIN Act related to NSBL&D is less than 600 words. The language is written in such a way that it allows reasonable freedom to engineer a solution that considers our stakeholders, threatened and endangered species and the American taxpayer.
Based on the flexibility allowed for design, it is too early to speculate about what the final solution will look like, or estimate a final cost.
Since the law was only recently enacted, it is important to emphasize the Corps requires reasonable time for analysis. The timeline of this analysis is difficult to predict, but it will involve additional studies before a final solution is determined.
The bottom line is that we intend to propose a cost-effective solution that addresses and balances the needs of all stakeholders, from local public to endangered species – and taxpayers in general.
Until then, there is additional analysis needed of the alternatives to determine how to best meet the intent of the law. This is a responsibility the Corps takes very seriously.
We have already been consulting with a number of stakeholders to include the Augusta Consortium, the Augusta Metro Chamber of Commerce, the Augusta mayor and other industrial and municipal partners. We will continue meeting with stakeholders and those from the community as we evaluate possible solutions. And we welcome input from anyone who has interest in the process.
One thing we can assure is this: The final product will be designed with the interests and safety of the stakeholders in mind, and will also be executed in the most cost-effective, environmentally sustainable manner.
We will provide updates to this process on this blog as they become available.
