THE
SUSQUEHANNA RIVER BASIN
The Susquehanna River spans 444 miles in length and drains approximately
27,500 square miles through three states, New York, Pennsylvania,
and Maryland. The Susquehanna River Basin is the second largest
east of the Mississippi River and the largest on the Atlantic
Seaboard. In the headwaters, there are two major branches of
the Susquehanna River; the North and West Branch. The North
Branch begins at Otsego Lake in Cooperstown, New York and meanders
through the Southern Tier and into Pennsylvania. The West Branch
originates in the hills of the Allegheny Mountains, flows through
the central region of Pennsylvania until the two branches converge
in Sunbury, Pennsylvania. In New York State, the Susquehanna
River Basin encompasses 14 counties with over 8,185 miles of
rivers and streams and 130 significant lakes (>6.4 acres),
and reservoirs. 1
The Susquehanna River is an important water body because it
contributes nearly one-half of the Chesapeake Bay's freshwater
supply. As such, a significant portion of the phosphorus, nitrogen,
and sediment pollution in the Chesapeake Bay originates within
the Susquehanna River Basin. 1
THE
CHESAPEAKE BAY
The Chesapeake Bay is the largest estuary in the United States
spanning 200 miles in length with over 11,684 miles of shoreline.
The Bay's width ranges from 3.4 miles near Aberdeen, Maryland
to 35 miles adjacent to the mouth of the Potomac River. The
average depth of the Bay, including all the tidal tributaries,
is relatively shallow at 21 feet. The surface area of the Chesapeake
and its tidal tributaries is about 4,480 square miles.
2
As an estuary, fresh water and salt water mix to become part
of an extremely productive and complex ecosystem. The Bay supplies
millions of pounds of seafood, provides natural habitat for
wildlife, offers a variety of recreational activities, and is
a major center for shipping and commerce. Oysters and blue crabs
are two major delicacies that are fished from the Bay. In 2001,
the value of commercial shellfish and finfish harvests totaled
to almost $175 million. The Bay also provides habitat to thousands
of plant and animal species. Waterfowl and other migratory birds
find food and shelter in the Bay area while some winter in the
Bay itself. The tidal freshwater tributaries provide spawning
and nursery sites for several fish species include the white
and yellow perch, striped bass, herring and shad. During the
warmer months, marine fish, including the bluefish, weakfish,
croaker, menhaden, flounder, and spot enter the Bay area to
feed on its rich food supply. 2
POLLUTION PROBLEMS
Data collected from the Susquehanna River
and the Chesapeake Bay show that it has poor water quality,
degraded habitats and fish and shellfish populations are decreasing.
The Bay and the rivers that contribute to the bay have high
levels of nitrogen, phosphorus and sediment. These pollutants
cause cloudy water, algal blooms, low oxygen levels and decreased
aquatic grasses. These all lead to poor fish habitat, places
restrictions on recreational usages and fish consumption, and
lessens the quality of drinking water supplies. The suspected
sources of these pollutants are from agricultural runoff, urban
and suburban runoff, municipal sewage, and airborne contaminants.
THE
SUSQUEHANNA RIVER BASIN COMPACT
The Susquehanna River Basin Compact was developed to address
the pollution problems its impacts on the Chesapeake Bay. The
compact was signed into law, by the States of New York, Pennsylvania,
Maryland, and the federal government on December 24, 1970. The
compact resulted in the creation of the Susquehanna River Basin
Commission (SRBC) and established its multi-state authority.
The SRBC is an agency that coordinates management efforts and
oversight of the river basin between the federal government
and each state with the basin. The members of Commission include
a federal representative, which is appointed by the President
of the United States and a designee of the governor from each
member state.
The SRBC acts in planning efforts and management of the water
resources of the Susquehanna River Basin. "The Commission
acts to reduce damages caused by floods, provide for the reasonable
and sustained development and use of surface and ground water
for municipal, agricultural, recreations, commercial and industrial
purposes; protect and restore fisheries, wetlands, and aquatic
habitat; protect water quality and in stream uses; and ensure
availability of flows to the Chesapeake bay."3
TOTAL
MAXIMUM DAILY LOAD (TMDL)
A TMDL is the amount of a specific pollutant A total maximum
daily load is an allowable amount of a pollutant that can enter
a waterbody, from both point and non-point sources, while still
maintaining good water quality standards. The TMDL is based
on the premise that each water resource (lake, stream, river,
etc.) can assimilate a certain amout of pollutants and keep
functioning in a healthy manner. The Clean Water Act, enforced
by the Environmental Protection Agency (EPA), requires all states
and territories to list impaired and threatened waters and develop
a TMDL to improve water quality of a specific watershed. The
process in developing a TMDL relies upon the collection of reliable
data to indentify pollution sources and then determine their
pollution loads. Based upon the data collected, allocations
and limits on discharges can be made for each pollution source.4
These allocations, which are based upon localized watersheds,
may affect municipal sewage treatment facilities, the agricultural
community, residential and urban property, and other industrial
facilities.

Utilizing a complex computer model, the Environmental Protection
Agency (EPA) through the Chesapeake Bay Program developed a
total annual load allocation for nitrogen (N), phosphorus (P)
and sediment, by state, that it considers to be the maximum
quantities that the Chesapeake Bay can receive and meet water
quality standards. This is called a Total Maximum Daily Load
or "TMDL". It is like a pollution diet for the Bay.
In mid-December, 2010 EPA officials accepted the state's Watershed
Implementation Plan (Plan) to reduce nutrients in agricultural
runoff, urban stormwater, and sewage treatment plant effluent
in New York's portion of the Chesapeake Bay watershed as shown
in the above table. New York's final Phase I Plan will result
in loads that are 14% under, and 5% and 2% over the EPA's sediment,
N and P allocations, respectively. The EPA accepted New York's
plans for addressing agricultural runoff and the state's current
permitting system for urban sewer systems. However, the EPA
closed the gaps between New York's Plan and EPA allocations
with an aggregate backstop for permitted waste treatment facilities.
Under the final plan, EPA calculated waste load allocations
using the N and P performance levels that New York committed
to, but assumes that significant wastewater treatment plants
are at current flow rather than design flow. The New York State
Department of Environmental Conservation (NYSDEC) will have
to review the treatment plants' permits during the next phase
of the TMDL and may have to make adjustments depending on how
the plants meet their individual pollution limits. Regardless
of sector, the EPA will regularly monitor the state's programs
to make sure they implement the pollution control plans, remain
on schedule for meeting water quality goals and achieve two-year
milestones. This oversight will include program review, objecting
to permits, and targeting compliance and enforcement actions
as necessary to meet water quality goals.
New York will be required to submit Phase II of the Plan in
June of 2011. In the second phase, the EPA has suggested nutrient
and sediment allocations be set at the county or small watershed
scale. The Upper Susquehanna Coalition of Conservation Districts
(USC) will be making the case to the NYSDEC and EPA that a robust
Plan can be developed without having to subject each county
to an allocation. Instead we propose a basin-wide approach,
with watershed teams, cooperation between counties, and targeting
the best projects in the optimal locations to minimize costs
while maximizing reductions to the Bay. This is the approach
that has been used successfully over the past decade.
In the short term, the USC, NYSDEC and other agencies will
begin implementing the Plan, tracking progress and reporting
to EPA. Results over the next few years will determine if there
needs to be changes in the Plan to meet the TMDL. If you have
any questions please feel free to contact your local Soil and
Water Conservation District or visit www.u-s-c.org

THE CHESAPEAKE BAY
TMDL: AFFECT ON THE CHENANGO COUNTY SWCD AND THE NRCS FIELD
OFFICE
The Soil and Water Conservation District and Natural Resources
Conservation Service (NRCS) have been implementing best management
practices since it's inception to limit agricultural runoff
and pollution from entering nearby waterways and major rivers.
The District continues to work with farmers to implement practices
and find funding to collect, store, and treat agricultural wastes
and by-products, assist farmers to establish grazing systems,
assist landowners in stabilizing stream bank erosion, as well
as implement many other conservation practices to lessen the
amount of agricultural nutrient pollution from entering the
watershed.
Because of the TMDL, more funding sources, on both the State
and federal level, will become available to the SWCD and NRCS,
as well as other agencies and individuals. The Natural Resources
Conservation Service (NRCS), through the 2008 Farm Bill, instituted
the Chesapeake Bay Watershed Initiative (CBWI), as a component
of the Environmental Quality Incentive Program (EQIP) to provide
assistance to producers in priority areas of the Upper Susquehanna
Watershed. The focus is to implement conservation practices
for livestock waste, cropland and grazing land resource concerns.
The National Fish and Wildlife Foundation (NFWF), in partnership
with the EPA and the Chesapeake Bay Program (CBP) has announced
a request for proposals for Innovative Nutrient and Sediment
Reduction projects to support approaches to expand the knowledge
on the most cost effective and sustainable approaches to reduce
or eliminate nutrient and sediment pollution to the Chesapeake
Bay and its tributaries.
