Reduction of nutrient impairments to our nation’s waters is a top priority for states and interstates. As discussed in detail in the Executive Summary & Overview below, ACWA has a long history of working with the U.S. Environmental Protection Agency (“EPA”) on strategies to reduce nitrogen and phosphorus loadings to waterbodies. EPA has continued to emphasize the importance of state adoption of numeric nutrient criteria (“NNC”) as the most effective mechanism for ensuring accountable and verifiable reductions.
However, states have long advanced that reductions also are being achieved via a rich mosaic of approaches that vary by state, pollutant of concern, sources, and collaborators. This report provides a high level summary of each state’s current approach to nutrient reduction. This report’s methodology, which was conducted in phases of survey, narrative drafting, and state review, is described below.
We are pleased that this report consists of responses from every state and the District of Columbia.
