Development of Nutrient Endpoints for Allegheny Plateau and Ridge and Valley Ecoregions of Pennsylvania: TMDL Application
Addendum to a report entitled "Development of Nutrient Endpoints for the Northern Piedmont Ecoregion of Pennsylvania: TMDL Application" dated November 30, 2007 which described the process to establish appropriate and scientifically defensible nutrient endpoints that are protective of aquatic life for use in nutrient TMDLs in the piedmont ecoregion. It described the process that was applied in detail, the results of those analyses, and the final recommended TP and TN endpoints. This addendum applies the same methodology to the development of nutrient endpoints for streams of the Ridge and Valley and Allegheny Plateau ecoregions of Pennsylvania.
