Thank you for your submittal, together with the other northeast states, of the Northeast Regional Mercury Total Maximum Daily Load (TMDL). The TMDL addresses all freshwater segments in the State of Connecticut, except for 11 segments listed in the TMDL as excluded due to the presence of local sources. The statewide application of the TMDL is based on the inclusion on Connecticut’s 2006 303(d) l...

The Total Maximum Daily Load (TMDL) program, established by U.S. federal law, drives U.S. water quality policy and management today. Mathematical models, in combination with field monitoring data, are widely used when developing TMDLs since they can potentially save time, reduce cost, and minimize the need for experimentally evaluating management alternatives. This article introduces the collec...

Systematic consideration of uncertainty in data, model structure, and other factors is generally unaddressed in most Total Maximum Daily Load (TMDL) calculations. Our previous studies developed the Management Objectives Constrained Analysis of Uncertainty (MOCAU) approach as an uncertainty analysis technique specifically for watershed water quality models, based on a synthetic case. In this stu...

An expert panel was convened to explore the use of adaptive implementation in the TMDL program, following a 2001 National Research Council report recommendation. This paper summarizes the panel’s report suggesting an adaptive implementation process for water quality management. In current practice, what the panel calls standard implementation, a plan for reducing pollutant loads to meet water q...

The establishment of a total maximum daily load (TMDL) is part of management process that results in the institution of watershed-based controls of otherwise unregulated sources of pollution. In California (USA), the implementation of a TMDL is driven forward in a process where watershed stakeholders are expected to cooperate on actions needed to improve ecosystem health. In the TMDL process, m...

Ecological restoration of the Chesapeake through the Chesapeake Bay total maximum daily load (TMDL) requires the reduction of nitrogen, phosphorus, and sediment loads in the Chesapeake watershed because of the tidal water quality impairments and damage to living resources they cause. Within the Chesapeake watershed, the Conowingo Reservoir has been filling in with sediment for almost a century ...
