Washington Post Article Highlights Wildlife Contribution to Bacteria Impairment
The following article was published in the Washington Post last Fall. It highlights the problems of wildlife bacteria contributions to urban waterways. In many cases, wildlife contributions prevent the attainment of bacteria standards established to protect public recreation. While some states have sought to ignore wildlife contributions and focus on bacteria of human origin, EPA’s latest guidance strongly recommends that bacteria from wildlife be counted along with that from livestock and human sources. The reason for this is that bacteria from wildlife present many of the same illness risks as from human sources.
This article is a classic example of why we need to refine recreational use designations to better address natural, wet weather, and other bacteria realities in urban waters.
Nutrient Trading Update: Pennsylvania Nutrient Credit Trading Underway . Red Barn, the first entity to have credits certified for trading by the Pennsylvania Department of the Environment, has initiated the first sale of nutrient credits in the state as well. The transaction will take place over a five-year period to developer Daniel Maisano, Dunn Lake LLC, for a Susquehanna County development. The development will use the credits toward permitting a package sewage treatment plant for a residential development. Under the Pennsylvania trading system, DEP must approve all credit proposals before the credits can be traded. More information about this program can be found here.

Red Barn Trading Company proposes one type of credit generating Best Management Practice (BMPs) on an existing poultry broiler farm in Union. The proposed BMP is manure exportation from the home farm. The home farm would export the manure that was previously applied to the cropland to be used on land outside the Chesapeake Bay Watershed. The new destination for manure that is exported is several nutrient deficient areas outside of the Chesapeake Bay watershed and in some cases outside of Pennsylvania. Nutrient Balance Plans will be developed as required for all importing farms/lands located outside the Chesapeake Bay watershed prior to land application and all manure application will be in accordance with all applicable state laws and regulations.
