Nutrient credit trading could significantly trim the cost of cleaning up the Chesapeake Bay, according to a new study released by the Chesapeake Bay Commission.
Nutrient credit trading is a system that enables one pollution source to meet its pollution reduction goals by purchasing those reductions from another source.
The economic analysis showed that nutrient credit trading could save 20 percent to as much as 80 percent of costs to meet pollution reduction goals called for in the Chesapeake Bay TMDL, the federal “pollution diet” to clean up the Bay. State and local governments must reduce nitrogen and phosphorus pollution from farms, wastewater treatment plants, stormwater systems and other sources to meet these goals by 2025.
The study recommends that governments define trading rules and protocols, provide information and technical assistance, and ensure compliance and enforcement to maximize cost benefits and guarantee trading programs actually deliver pollution reductions.
To date, four Chesapeake Bay watershed states – Maryland, Pennsylvania, Virginia and West Virginia – have initiated water quality trading programs.

By the 1760s, the Chesapeake Bay watershed’s first settlers were pushing farther west; they negotiated new lands and redrew the lines between European and Native American territories. But when surveyors visited one of the newly acquired regions – Lycoming County, Pennsylvania – they met a European settler named Larry Burt. Disregarding the “territories” concept, Larry had lived in the area for several years, trading with the Native Americans and marrying a Native American woman. The stream became known “Larrys Creek,” and is the only creek in the county whose Native American name remains unknown.

For the next few years, this 23-mile-long tributary to the West Branch of the Susquehanna River would become a disputed border between colonial and Native American lands. Settlers living in the area were considered “Fair Play Men.” These residents were not governed or protected by the colonial government of Pennsylvania, and even made their own Declaration of Independence.
The first fork of Larrys Creek begins in northern Lycoming County in Cogan House Township, just south of a stretch of Appalachian Mountains known as Steam Valley.
Flowing southwest, the creek runs through the village of Cogan House and under the Cogan House Covered Bridge. The oldest of Lycoming County’s three covered bridges, the Cogan House Covered Bridge has survived massive floods and storms since its construction in 1877.

Larrys Creek then winds through Pennsylvania State Game Lands Number 114, where a rough trail follows the stream for a few miles. It meets the second (westernmost) fork of Larrys Creek at Salladasburg, and flows south into the mouth of the Susquehanna River at the town of Larrys Creek.
If you travel to Larrys Creek today, you may find it to be a rather remote destination. But just over a hundred years ago, the creek and its watershed were home to 53 sawmills, making Larrys Creek a bustling industrial center. A 1903 newspaper article claimed, “No other stream in the country had so many mills in so small a territory.” As a result, much of the land was clear cut and virtually devoid of forests.
Today, more than 80 percent of the watershed is forested and nearly 9,000 acres of second-growth forest are protected for hunting and trout fishing.
