Nutrient Framework to Reduce Phosphorus and Nitrogen Pollution

Contact: Ryan Baldwin 517-290-9012

Introduction

Nutrient pollution of our nation's surface waters has been implicated as one of the top causes of water quality impairment.  In a March 16, 2011 memo the United States Environmental Protection Agency (EPA) stated its commitment to working with states and other stakeholders to accelerate the reduction of nitrogen and phosphorus loadings to our nation's waters.  Working in partnership with the EPA, EGLE is presenting the steps that have been and will be taken in Michigan to protect surface waters from excessive nitrogen and phosphorus pollution.  EGLE intends to work with the EPA to set load-reduction goals for prioritized watersheds and reduce nutrient loadings through a combination of point-source and nonpoint source reduction activities.
