Scope and Purpose

The charge of the Water Quality Goal Implementation Team (WQGIT) is to evaluate, focus, and accelerate the implementation of practices, policies, programs that will restore water quality in the Chesapeake Bay and its tributaries to conditions that support living resources and protect human health. The Team reports to the Management Board and Principals’ Staff Committee. Functions include:

  • Provide a forum for discussion, exchange of information, and evaluation among federal, state, and local agencies, river basin commissions, industry groups, universities, and other interested parties on water quality goals, data, modeling, authorities, and restoration efforts.
  • Evaluate and promote strategies to reduce nutrient, sediment, and chemical contaminant loads from municipal, industrial and onsite wastewater; agricultural lands and animal operations; urban and suburban stormwater; forested lands; tidal and in-stream sediment; and air emissions.
  • Promote consistent, uniform and transparent processes to model, track, report, and verify water quality restoration efforts.
  • Identify, define, quantify, and incorporate pollutant reduction and conservation practices into the Chesapeake Bay Program decision support system.
  • Provide technical expertise and leadership to support the development, implementation, and tracking of the Chesapeake Bay TMDL, Watershed Implementation Plans, and two-year milestones that support long-term Bay restoration goals.

Projects and Resources

Chesapeake Bay Watershed Data Dashboard

The Watershed Data Dashboard is a visualization tool to consolidate and provide accessibility to Chesapeake Bay watershed monitoring, modeling, trends, projections and explanations for use in watershed management planning and implementation.

Access the WIP Data Dashboard here: https://gis.chesapeakebay.net/wip/dashboard/

Multiple Benefits of Nutrient and Sediment BMPs

Jurisdictions and planners are encouraged to consider additional benefits of BMPs beyond nutrient and sediment load reductions in development and implementation of the Phase III WIPs. The following resources are available in this effort:

A co-benefits scoring report was developed to provide a scoring matrix for additional benefits from BMP implementation. The report and scoring matrix were used in the development of 12 Principles for Phase III WIPs fact sheets describe the co-benefits that are possible when BMPs are selected in a thoughtful manner with site-specific conditions in mind. Each includes contact information for each watershed jurisdiction for more information.

These resources are also available for download through CAST: http://cast.chesapeakebay.net/Documentation/DevelopPlans

Additional resources for the Phase III WIPs are available on the Phase III WIP Tools web page.

Phase III WIP Expectations

On January 18, EPA released its Interim Phase III WIP expectations document which is intended to support the development and implementation of the jurisdictions’ Phase III WIPs and to assist the jurisdictions with stakeholder engagement during WIP development. EPA intends to further modify the sections on accounting for growth, Conowingo Dam, and climate change to incorporate decisions made by the Principals’ Staff Committee at their Spring 2017 retreat.

Phase 6 Scenario Builder Review

Scenario Builder is a data management tool that provides estimates of land use acres, nutrient inputs, cropland attributes, and best management practice (BMP) implementation data to the Chesapeake Bay Program Partnership's Phase 6 Watershed Model. The documentation and initial application rates to crops that are provided in the link below will help inform a full partnership review of the tool's documentation, during which the Agricultural Modeling Subcommittee (AMS) hopes to receive comments that could result in improvements to the tool in the spring and summer of 2016.


June 23, 2016:
The Agriculture Workgroup requested two nutrient spread application procedures be tested in advance of its July 20-21 face-to-face meeting. Nutrient applications from inorganic fertilizer, manure and biosolids from both versions are now available for download at ftp://ftp.chesapeakebay.net/Modeling/Phase6/Ph6Calibration_Beta2/20160401/inputs/ScenarioBuilder/. The two procedures are briefly described below.

  • The first procedure, known as Beta 3a, relies upon an estimate of fertilizer sales across the watershed, and distributes those sales to counties based upon dollars spent by a county, as reported by the Census of Agriculture, and inorganic crop nutrient need after manure and biosolids applications are made. Using this method, the total pounds of inorganic fertilizer applied across the watershed are equal (never above or below) the total pounds of fertilizer sales estimated across the watershed.
  • The second procedure, known as Beta 3b, applies inorganic fertilizer to fulfill crop nutrient need after manure and biosolids applications are made. Using this method, the total pounds of inorganic fertilizer applied across the watershed may exceed or be lower than the estimated fertilizer sales across the watershed. This procedure is similar in method to the current Phase 5.3.2 inorganic fertilizer application procedure.
  • States are encouraged to review the results of each procedure prior to the July 20 meeting. A detailed analysis of the two methods, including areas of disagreement between the two methods, will be provided at the meeting.
  • Please do not hesitate to contact Matt Johnston at mjohnston@chesapeakebay.net or 410-267-5707 if you have any questions.

August 23, 2016:

At its July meeting, the Agriculture Workgroup approved the use of AAPFCO fertilizer sales data to inform applications of inorganic fertilizer by county during the calibration period (1984-2013) of the Phase 6 Watershed Model. The Workgroup approved distributing total pounds of inorganic fertilizer sold across the watershed to counties based solely upon inorganic crop application goals left over after applications of biosolids and manure. The files attached below ('Beta 3a1-XXX.xlsx') provide applications and legume fixation by land use and crop following these new recommendations. Please contact Matt Johnston at 410-267-5707 if you have any questions following review of this information.

To view the new time series data for Beta 3a(1) (also known as Beta 3c) on Tableau, please use the following link: https://public.tableau.com/profile/olivia.devereux#!/vizhome/ChesapeakeBayPhase6WatershedModelInputs/Introduction


Improvements for the April calibration include:
• Inorganic fertilizer was distributed to crops only after all BMPs were simulated that would impact the amount of manure available to crops and the amount of agricultural acres with remaining nutrient application needs.
• Manure mineralization rates, which impact the amount of manure nutrients available to crops, were updated to reflect typical nutrient management mineralization rates by decade.
• Manure recoverability, or the amount of manure generated in a barnyard that can be made available to crops, before and after the implementation of Animal Waste Management Systems was updated to reflect estimates provided in  http://www.nrcs.usda.gov/Internet/FSE_DOCUMENTS/nrcs143_012131.pdf.
• Acres of barnyards or feeding facilities were updated to reflect the Bay Program’s best estimates per animal type.
• Nutrient application goals for the minor crops, emmer, spelt and triticale, were based upon state-recommended applications on a per acre basis as very little yield data was available to vary the application goals by annual yield.

Governance Protocols

The WQGIT Governance Protocols articulate the decision-making procedures and cross-sector communication processes observed by the WQGIT and its Workgroups. The WQGIT Governance Protocols are consistent with the governance decisions made by the Chesapeake Bay Program partnership's Principals' Staff Committee

Water Quality Management Strategy

The Water Quality Management Strategy provides broad, overarching direction for how to monitor, assess and report progress towards reaching the 2017 Watershed Implementation Plan (WIP) Outcome, the 2025 WIP Outcome, and the Water Quality Standards Attainment & Monitoring Outcome from the 2014 Watershed Agreement. The strategy will be further supported by two-year work plans summarizing the specific commitments, short-term actions and resources required for success.

BMP Expert Panels

The seven Chesapeake Bay watershed jurisdictions implement Best Management Practices (BMPs) to achieve the goals set forth in the 2010 Bay TMDL. Through the Protocol for Development, Review, and Approval of Loading and Effectiveness Estimates for Nutrient and Sediment Controls (BMP Protocol), newer practices and technologies are considered and evaluated for inclusion in the Chesapeake Bay Program partnership modeling tools.

Phase III WIP Stakeholder Assessment

In preparation for the development of Phase III WIPs in 2017-2018, the WQGIT has undertaken a stakeholder assessment to identify lessons learned from the Phase I and Phase II WIP processes that should be applied to the Phase III WIPs. The stakeholder assessment should recommend improvements to the WIP development, evaluation, implementation and oversight processes so that the Phase III WIPs create effective blueprints for implementation through 2025.

Chesapeake Bay TMDL 2017 Midpoint Assessment

The December 2010 Chesapeake Bay Total Maximum Daily Load (Bay TMDL) calls for an assessment in 2017 to review our progress toward meeting the nutrient and sediment pollutant load reductions identified in the 2010 Bay TMDL, Phase I and Phase II Watershed Implementation Plans (WIPs) and two-year milestones.
