EGLE Process for Obtaining Authorization to Use Tracer Dyes

In compliance with the provisions R323.1097 of Part 31, Water Resources Protection, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (Act 451), EGLE has regulatory jurisdiction over projects involving the direct or indirect application of tracer dyes to surface waters of the state.

An entity is authorized to apply tracer dyes to surface waters of the state by following the provisions under the appropriate certification.  The certifications are as follows:

For applications or discharges of tracer dyes appearing on the Acceptable Michigan Tracer Dye List to surface waters of the state, coverage under the General Rule 97 Certification of Approval Authorizing Tracer Dyes in Surface Waters is necessary.  This process is initiated by submittal of a Notification of Intent (NOI PDF fill-in form or NOI DOCX fill-in form) by the applicant.  Upon acknowledgement from EGLE that a Notification of Intent has been received, the applicant is authorized to commence tracer dye study in compliance with the certification.  Acknowledgement of receipt of the Notification of Intent can be determined at Tracer Dyes information, or by contacting Ms. Susan Ashcraft at 517-284-6660 or by e-mail at AshcraftS@michigan.gov.

For any application or discharge of tracer dyes to waters of the state that is not authorized by Certifications R97-18/001, an Individual Rule 97 Certification of Approval is necessary.  Upon receipt of approval by EGLE, the applicant is authorized to commence treatment under the individual Rule 97 approval.
