MOTION TO INTERVENE OF STEWARDS OF THE LOWER SUSQUEHANNA, THE
LOWER SUSEQUEHANNA RIVERKEEPER, AND WATERKEEPERS CHESAPEAKE
Pursuant to 18 C.F.R. § 385.214(a)(3), Stewards of the Lower Susquehanna, Inc.,
(“SOLS”), the Lower Susquehanna Riverkeeper (“Riverkeeper”), and Waterkeepers Chesapeake
move to intervene in this proceeding, which addresses the relicensing of Exelon Generation
Company, LLC’s Conowingo Hydroelectric Project. The Conowingo Hydroelectric Project
(“Conowingo Dam”) dams the Susquehanna River about 10 miles upstream of the river’s outlet
to the Chesapeake Bay. As discussed below, Movants both have and represent interests that may
be directly affected by the outcome of this proceeding, and their participation is in the public
interest.1 Movants support relicensing of the Dam so long as the final license includes adequate
plans to mitigate the environmental and recreational impacts caused by the Dam.
DESCRIPTION OF INTERVENORS
SOLS is a non-profit environmental advocacy organization headquartered in
Wrightsville, Pennsylvania. Established in 2005, SOLS has more than 100 individual and
organization members, and its mission is to protect and improve the ecological and aesthetic
integrity of the Lower Susquehanna Watershed and Chesapeake Bay. The Lower Susquehanna
Riverkeeper leads SOLS’ work in advocating for strong environmental standards and policies 1 SOLS previously moved to intervene in this proceeding by motion filed September 7, 2012. No one filed an opposition. Under FERC’s regulations, SOLS is thus already a party. 18 C.F.R. § 385.214(c)(1). SOLS files this motion both as a precautionary measure in light of FERC’s Federal Register notice announcing the project and soliciting motions to intervene, 78 Fed. Reg. 26,343 (May 6, 2013), and to add new contacts to the service list.
that protect and serve the public interest. Both SOLS and the Riverkeeper participated actively in
earlier phases of the Dam’s relicensing process, including by filing comments. E.g.

Accession No. 20120321-5173, Mar. 20, 2012).
Waterkeepers Chesapeake is a coalition of 18 independent Waterkeeper programs
operating throughout the Chesapeake and Delmarva Coastal Bays Watersheds.2 The coalition
works to protect and improve the health of the Chesapeake Bay and the waterways in the region,
including the Lower Susquehanna. Waterkeepers Chesapeake aims to amplify the voices of the
individual Waterkeeper groups, and to work together on campaigns to stop pollution throughout
SOLS and the Lower Susquehanna Riverkeeper’s geographic focus begins at the
Susquehanna River’s confluence with the West Branch at Sunbury, Pennsylvania, and reaches
downstream to the Chesapeake Bay at Havre de Grace, Maryland. In total, the territory
stewarded by SOLS and the Riverkeeper encompasses over 140 miles of the Susquehanna River
and approximately 9,200 square miles in the Lower Susquehanna sub-basin, including the area
immediately around the Dam. Waterkeepers Chesapeake’s geographic sweep includes the Lower
Susquehanna River watershed, as well as the Chesapeake and Coastal Bays and their tributaries

The following people should be added to the service list for this proceeding:
GROUNDS FOR INTERVENTION
SOLS members and the Riverkeeper use the Lower Susquehanna watershed for fishing,
hunting, boating, domestic uses, and for its scenic and historic value. Many of SOLS’ more than
100 members live, work, and recreate along the Susquehanna River and its tributaries in
Lancaster, York, and Dauphin counties in Pennsylvania, and in Cecil and Harford counties, in
Maryland. The Riverkeeper and SOLS members who use watershed resources of the Lower
Susquehanna north of the Dam have an interest in protecting themselves from inappropriate,
irresponsible, or adverse conditions adopted in a final Dam license that affect those resources. So
too do the Riverkeeper and members residing and utilizing watershed resources in Cecil and
Harford counties, the area directly adjacent to the Dam. In addition, because this relicensing
proceeding affects the Chesapeake Bay, as described below, Waterkeepers Chesapeake’s
interests and its members’ interests will be directly affected by it.
Conowingo Dam has impacts that are of particular interest to Movants and their members
in three areas. First, this proceeding is vital for determining what will be done about the Dam’s
impoundment and release of large amounts of pollutants—especially sediment—that affect
Movants’ recreational and aesthetic interests. Sediment is a water pollutant that both carries other
pollutants, like phosphorous and nitrogen, and reduces the clarity of the water in the Chesapeake
Bay, thus degrading water quality and vegetation in the Bay. See
EPA, Chesapeake Bay Total
Maximum Daily Load for Nitrogen, Phosphorous and Sediment
2-7 (Dec. 29, 2010), available at
3_final.pdf. The Susquehanna is the largest source of sediment to the Chesapeake Bay. Id.
to -4 & fig.4-5, available at
At present, the Dam traps sediment present within the water column in Conowingo Pond,
thus typically limiting average annual loading of sediment to the Bay. Although Conowingo
Pond still has some sediment-trapping capacity left, it is quite near—and continues to
approach—a state of “equilibrium,” under which the average annual amount of sediment passing
the Dam generally will equal the amount trapped by the Dam. Robert M. Hirsch, U.S. Geological
Survey, Scientific Investigations Report 2012-5185, Flux of Nitrogen, Phosphorus, and
Suspended Sediment from the Susquehanna River Basin to the Chesapeake Bay during Tropical
Storm Lee, September 2011, as an Indicator of the Effects of Reservoir Sedimentation on Water

(explaining that other dams and upper portion of Conowingo Pond have reached equilibrium and
that deposition in rest of Conowingo Pond “is asymptotically approaching” Pond’s capacity). As
it approaches equilibrium, the Dam traps less and less sediment. Id.
at 12. Further, during major
storms, a portion of this previously trapped sediment is “scoured” to create individual pollution
events that carry higher quantities of sediment, phosphorus, and nitrogen into the Bay than would
have occurred if the Dam were not present. See id.
at 13 (“The concentrations of total nitrogen,
total phosphorus, and suspended sediment measured in samples collected at discharges greater
than about 100,000 or 200,000 cubic feet per second currently (2012) are substantially higher
Exelon seeks a new license that will last until 2060, which is well after equilibrium will
be reached at Conowingo Dam, to say nothing of the changes that have already occurred and will
only worsen. See
Exelon Generation Company, LLC’s Final License Application for the
Conowingo Hydroelectric Project and Request for Waiver of the Requirement to Include a Draft
Biological Assessment 1, 28-29, 32 (FERC Accession No. 20120830-5174, Aug. 30, 2012);
, at 13 (“the predicted changes are not just a theoretical issue for future
consideration, but are already underway.”). Thus, it is important to address in this relicensing
proceeding the long-term ecological consequences and impacts on human uses of the affected
water bodies caused by sediment impoundment and discharge by Conowingo Dam. Because of
the importance of this proceeding for water quality in the Susquehanna and the Chesapeake Bay,
which Movants and their members use and enjoy, Movants intend to press strongly on FERC and
Exelon to implement meaningful remediation and/or mitigation conditions concerning sediment
impoundment and discharge from Conowingo Dam.
Second, Conowingo Dam has a powerful, negative effect on the American eel population
the Susquehanna, in which Movants have interests. A catadromous fish, the American eel spends
key periods of its life in rivers. Historically, the Susquehanna was one of those rivers, but the
Dam effectively reduces historic eel range to just the lower 10 miles of the Susquehanna River.

numbers to the Susquehanna is important for the eel and the Susquehanna River’s ecosystem.

Hydroelectric and other projects upstream.”); Steven P. Minkkinen et al.

Also, reviving the largely extirpated American eel population in a large section of the
Susquehanna is likely to improve water quality in the Susquehanna watershed, and will thus
doubly enhance the integrity and sustainability of the ecological systems. The American eel is
the best host species for the glochidia—the larvae—of the Eastern elliptio freshwater mussel,
historically abundant in the Susquehanna. William A. Lellis et al.
, Newly Documented Host
Fishes for the Eastern Elliptio Mussel
Elliptio complanata, 4 J. Fish & Wildlife Mgmt. 75, 79
(2013). These mussels are effective natural filters of river water. Minkkinen, supra
, at 3. They
are prevalent in other rivers that are not dammed, like the Delaware, but they are not nearly as
common in the Susquehanna. Id.
The presence of more American eel, and in turn more elliptio
mussels, in the Susquehanna equates to better water quality in the Susquehanna watershed.
SOLS members and the Riverkeeper live, work, and recreate along the Susquehanna, and have
aesthetic and recreational interests in a fully functional, cleaner Susquehanna River ecosystem
that includes historical levels of American eel.
Finally, Conowingo Dam has a catwalk that historically was accessible to the public for
recreational fishing. In the name of security, access to the catwalk was cut off after September
11, 2001, an arbitrary decision considering that several other comparable “security risks” remain
apparently unaddressed. These include trucks driving on the Dam, which forms part of U.S.
Highway 1, and the fact that other FERC projects on the Lower Susquehanna River still allow
for access similar to what the catwalk used to afford the public. Fishing from the catwalk
provides an experience different from—and in key respects better than— the alternatives now
provided. SOLS members would like to regain access to the catwalk so they can recreationally
fish from it as originally promised by the Dam’s builders and operators to the public decades
ago. Movants will press FERC to require Exelon to identify options for addressing security while
Movants and their members use the Lower Susquehanna and have recreational and
aesthetic interests in it. As described above, those interests will be directly affected in this
proceeding. Movants thus satisfy FERC’s requirements for intervention. 18 C.F.R.
Further, as well as being justified based on their direct interests, Movants’ intervention
should be granted because their participation serves the public interest. Movants are neither
governmental actors nor private businesses, but are, or are composed of, individual citizens with
strong interests in environmental issues affected by the Dam’s relicensing. They will bring a new
perspective to this proceeding because their interests and goals for this project are different from
those of governmental actors and private businesses, which are the only types of parties on the
service list addressing the issues described above. Thus, intervention should also be granted
because Movants’ participation will serve the public interest by providing a new perspective,
enhancing FERC’s decision-making. Id.
For the foregoing reasons, FERC should grant this motion to intervene.
