Development of a Model Monitoring Program for a DOT
Research Idea Scope
Many NPDES Permits require DOTs to monitor receiving waters to
characterize runoff from DOT facilities, assess the effectiveness of BMPs, and
for compliance with TMDLs. Monitoring programs require considerable time and resources
to implement. The objectives of DOT monitoring programs may not be well
defined, and the data may not be used fully to provide feedback to improve the
performance of the stormwater program.
A primary purpose of this research is to develop monitoring program
study questions. The study questions should define the most important data gaps
and data needs to improve the performance of the DOTs stormwater program. There
is also a need to examine sampling protocols to determine the most appropriate
approach for DOTs, as well as to establish a consistent recommendation
nationally to ensure that data across the US is comparable.
Task 1 – Literature
Review, Compilation of Data and Survey of State Practices and Experience
The literature review and the data compilation will focus on the
Current DOT monitoring programs;
Study questions for DOT monitoring programs;
Protocols for BMP effectiveness testing;
Sampling protocols by constituent.
Task 2 – Develop Model
Program Study Questions
Work under this task will develop study questions that are appropriate
for a DOT stormwater program. This task will also explore the conditions under
which (if any) a DOT should participate in receiving water sampling and
analysis. The study questions should ensure that the data provided by the
monitoring program is of value to the DOT in improving the performance of the
overall stormwater program. Study questions for DOT participation in TMDLs
should also be provided.
Task 3 – Develop Model
This task will develop a framework for a standard monitoring program.
The framework will include sampling site selection, sampling protocol,
appropriate detection limits (for example, is the same level of sensitivity of
analysis appropriate for answering the study question), and suggested
constituents for a baseline program. The framework will also define feedback
loops for the monitoring data to evaluate the potential for changes in the DOTs
