Watershed Implementation Plans (WIPs) include detailed, specific steps each of the seven Bay watershed jurisdictions will take to meet the pollution reduction goals of the Chesapeake Bay Total Maximum Daily Load (TMDL) by 2025. These plans consider such things as ecological restoration and sustainability while allowing for greater transparency and accountability for improved performance.
What are WIPs?
The Chesapeake Bay TMDL requires reductions of nitrogen, phosphorus and sediment. This federal effort is intended to obtain water quality standards for each of the Bay’s tidal segments, tributaries and embayments listed as impaired under 303(d) of the Clean Water Act. Each watershed jurisdiction has created a Watershed Implementation Plan, often called a WIP, that documents how the jurisdiction will partner with federal and local governments to achieve and maintain water quality standards.
There are three phases of WIPs:
- Phase I and Phase II WIPs were developed and submitted to EPA in 2010 and 2012, respectively. Both Phase I and Phase II WIPs describe actions and controls to be implemented by 2017 and 2025 to achieve applicable water quality standards.
- Phase III WIPs will be developed by jurisdictions based on a midpoint assessment of progress and scientific analyses that is currently underway through 2017. Phase III WIPs will provide information on actions the Bay jurisdictions intend to implement between 2018 and 2025 to meet the Bay restoration goals.
