Dye Trace Registration

Who Needs One?

Anyone performing a dye trace study in streams or groundwater systems of the state should complete the registration form.

What Information Must I Provide?

Applicants must submit the "Tennessee Department of Environment and Conservation Dye Trace Registration" form (Form CN-1112) 2 weeks prior to the planned trace study. Applicants provide information about the owner/operator of the facility necessitating the trace, person/company performing the trace, the reason for the trace, injection/receptor locations, and the types and amounts of dyes to be used.

Form Description Form Number
Dye Trace Registration CN-1112

How Will My Application Be Processed?

Completed application forms should be submitted through the online Form CN-1112. The information in the registration will be shared with the TDEC Division of Water Resources staff and the TDEC Public Information Officer so that these staff are informed about the dye trace project and can answer potential inquiries from the public that may be received.

What Fees Are Required?

There are no fees for Dye Trace Registration.

What Do I Do After the Registration is Submitted?

The applicant may proceed with dye tracing activities after two weeks have passed from the form submission date. The Division encourages persons conducting dye tracing to implement best practices to minimize concentrations of dyes to the extent practical by using appropriate receptor methods (e.g., charcoal receptors, field fluorometers, etc.) and avoiding visual detection of dyes. Higher concentrations of dyes that are visually detectable in streams can cause concern from the general public.

The applicant is also responsible for sending the Division a copy of the dye trace results. The form submission is valid for the dye trace project that was registered; additional studies require the completion of an additional application form online.

Dye trace results reports and any questions can be directed to Brian.Ham@TN.gov

What Are the Division’s Rights and Responsibilities?

The Division of Water Resources is responsible for protecting the state’s drinking water quality. The Division may observe the requested dye trace if it is considered a critical trace or has potential to impact drinking water supplies. Any person who violates or fails to comply with the rules, regulations, or any state and federal water quality standards may be subject to civil penalties.
