DEVELOPING TRIBUTARY STRATEGIES FOR RESTORING CHESAPEAKE BAY AND RIVER WATER QUALITY Menu of Actions/Analyses/Support Activities the Chesapeake Bay Program Office Can Provide to the Watershed States and Their Tributary Strategy Teams Watershed Model Scenarios Time series of progress scenarios since 1985 "What if we.." type of BMP implementation/treatment upgrades scenarios Actual hydrology scenarios Further exploration and analysis of watershed specific issues/questions (forested loads, reduction capacity, anthropogenic vs. natural loads, etc.) Sources and Loadings Analysis Development of watershed specific nutrient/sediment budgets More in-depth graphical and tabular displays of nutrient/sediment sources, edge of stream loads, delivered loads to tidal waters Analysis and graphical displays of directly monitored and model simulated sources of nitrogen, phosphorus and sediment Water Quality Model Scenarios Running water quality model scenarios to evaluate Bay tidal water quality response to different levels of BMP implementation/treatment upgrades Evaluation of the relative impacts on other basins' water quality of different levels/geographical placement of BMP implementation/treatment upgrades USGS SPARROW Model Analysis Presentation and in-depth analysis of watershed specific edge of stream and delivered nitrogen and phosphorus loads by different sources Analysis of the geographic significance of local areas as principal sources of nitrogen and/or phosphorus within a small watershed and to downstream tidal waters Water Quality Analysis Trends in water quality S Free flowing rivers and streams (concentration and load trends) S River input (concentration and load trends) S Tidal tributaries and Bay mainstem Criteria attainment assessment S Volume of dissolved oxygen criteria attainment S Surface area of chlorophyll a criteria attainment S Surface area of water clarity criteria attainment S Acreages of underwater bay grasses compared with restoration goal acreage S Current status (2000-2002) and long term trends (1985-2002) in criteria attainment Diagnostics of Bay criteria non-attainment ------- Causes of reduced water clarity Causes of excessive algal growth Cause of low dissolved oxygen Cost Effectiveness Analysis (Planning to build analysis capability within the CBPO this summer) Presentation Material Generation Power point slides generation Generation of tributary basin/state specific graphics on a range of topics Production of briefing materials Making Presentations to Partner Specified Audiences Technical groups Tributary Strategy Teams Community watershed organizations/business groups etc. Public audiences Public Communication Assistance with press contacts/information/publication Production of general or targeted audience "backgrounders" Ensuring Access to Wide Array of Data/Information/Publications Watershed profiles (on the Chesapeake Bay Program web site) to enable partners to generate tributary strategy basin specific profiles on-line Forging linkages to partners data/information management systems to make data readily accessible Menu of Actions/Analyses/Support Activities the Chesapeake Bay Program Office Can Provide to MD, VA, DE and DC During Their Bay Water Quality Standards Adoption Economic Analysis Support for State Use Attainability Analysis Providing access to economic analysis contractor support Assistance with Responding to Public Comments Providing support in responding to technical comments and criteria implementation issues Participation in Public Forums Making presentations; lining up EPA/other expert "witnesses" Participation on Convened Special Technical Stakeholder Groups Providing access to economic analysis contractor support Ensuring EPA Region/Headquarters is Engaged When/Where Needed Getting EPA input early on and up-front throughout the adoption process Updated: June 10, 2003 ------- |
