Phase 3 WIP BMP Information
BMP information for each Bay jurisdiction in Phase 3 WIPs were synthesized into charts to assess BMP effectiveness, BMP cost-effectiveness, and overall costs. The charts are available at the link below. View the most effective nitrogen and phosphorus BMPs in the WIP3 as measured by percent of total reduction in the BMP Effectiveness charts. Determine the most cost-effective nitrogen and phosphorus BMPs in the WIP3 as measured by cost/year to reduce a pound of each nutrient in the BMP Cost-Effectiveness charts. Costs of all BMPs for the most recent annual progress year and WIP3 by state and sector are presented in the Overall Costs charts.
The Chesapeake Bay Program and its partners compiled tributary basin summaries for 12 major tributaries or tributary groups in the Chesapeake Bay Watershed. These documents summarize the following in one place: 1) How tidal water quality changes over time; 2) How factors that drive those changes change over time; and, 3) Current state of the science on connecting change in aquatic conditions to its drivers.

Scientists calculate flow-adjusted trends in nitrogen, phosphorus and sediment levels to better determine whether pollution has changed over time. You can download the data for nitrogen, phosphorus and sediment from 1990 forward. The data above the River Input Monitoring (RIM) stations has been adjusted for variations in flow by USGS using the Weighted Regressions on Time, Discharge, and Season (WRTDS) model (Moyer and Blomquist, 2018).
Reports, maps, and other explanatory information is available to show the changes in water quality measured at the sampling stations in the non-tidal network. USGS's primary findings are:
- For nitrogen loads: 41 percent of the NTN stations are improving, whereas 40 percent are degrading, and the remaining 19 percent have no trend.
- For phosphorus loads: 44 percent of the NTN stations are improving, whereas one-third are degrading, and the remainder are showing no trend.
- For suspended-sediment loads: 20 percent of the NTN stations are improving, whereas 42 percent are degrading, and the remainder are showing no trend.
As of December 2010, all BMP information submitted to the Chesapeake Bay Program Office must be in a format compatible with the National Environmental Information Exchange Network (NEIEN) protocols that dictate the use of BMP-specific fields and units. Such information is utilized by CAST for the estimation of nutrient and sediment loads generated by different source areas within the Chesapeake Bay watershed.
National Environmental Exchange Network (NEIEN)
BMP information is submitted by the major jurisdictions to the Chesapeake Bay Program Office using NEIEN. NEIEN protocols dictate the use of BMP-specific fields and units. Such information is utilized by CAST for the estimation of nutrient and sediment loads generated by different source areas within the Chesapeake Bay watershed.
The 2010 Chesapeake Bay TMDL for Nitrogen, Phosphorus and Sediment set allocations for the Bay. Major jurisdictions create Watershed Implementation Plans for how to achieve the allocations. The Phase III W atershed Implementation Plans are under development and Interim Expectations have been established. BMPs are expected to be verified. Information on verification is below.

Federal Facility User Guide for Frequently Asked Questions
This simple “How To” document will walk you through seven commonly-asked questions that can be used to determine what information is in CAST for your federal agency and help you build an effective and efficient implementation plan.
Annual Progress Reporting Templates
Federal facilities reporting BMP implementation toward meeting the Chesapeake Bay TMDL are encouraged to use the template specific to each state when reporting. Data are reported to each state, who then merges data from federal facilities and multiple other sources for reporting to the Chesapeake Bay Program.
Any questions on annual progress reporting should be directed to Vanessa Van Note at VanNote.Vanessa@epa.gov or 239-910-1801 or the state representatives listed here: Tracking and Reporting Leads and Contact Information by Jurisdiction. Please verify with the state representative that the template below is current.
Templates (updated 9/1/2020):
- District of Columbia
- New York
- Virginia: All reporting organizations first need to have an authorized user register with the DEQ BMP Warehouse and have their role established. At that time, they can download the urban-suburban general upload template. It is the same template for all entities who need to report BMP data to VA. Please do so before you wish to upload anything because DEQ makes updates to the template and publishes new ones to the application. Contact William Keeling, DEQ, for more information.
- West Virginia
Milestones for 2016 to 2017
A Protocol was established for the 2016 to 2017 Milestones. While not applicable to the Phase III WIPs or future milestones, that information is below for archival purposes.
