Maryland’s 2016 Triennial Review of Water Quality Standards

On March 14, 2018, the Secretary of the Environment adopted amendments to the water quality standards regulations. Final action on the regulations was published in the March 30, 2018 edition of the Maryland Register Online. EPA approved Maryland’s amendments and Triennial Review of Water Quality Standards on July 11, 2018.
As part of the public review process, MDE published a notice of proposed action in the May 26, 2017 issue of the Maryland Register. This marked the beginning of the public comment period that ended on July 10, 2017 (please note that the public comment period was extended). During this public comment period MDE also held a public hearing on June 13, 2017 in Baltimore.
