Community involvement and public participation are an essential part of EGLE’s mission, vision, and values.
SARA Title III establishes requirements regarding emergency planning and "Community Right-to-Know" reporting on hazardous and toxic chemicals for federal, state, local, and tribal governments, as well as regulated facilities.
Resources and information on utilizing RRD's data exchange and the Inventory of Facilities.
An interactive map displaying contaminated sites throughout Michigan regulated under Parts 213, 201, and 211.
The Michigan Department of Environment, Great Lakes, and Energy’s (EGLE) Water Well Viewer (WWV), is an interactive mapping system that displays water wells along with other information, such as wellhead protection areas, underground storage tanks, and sites of environmental contamination. Water well locations have been identified by address matching, the use of global positioning systems (GPS), and by legal descriptions.
This system allows water well drilling and pump installation contractors to submit water well records.
EGLE's interactive calendar is designed to provide timely information on decisions before the Director, proposed settlements of contested cases, administrative rules promulgation, public hearings, meetings and comment deadlines, and environmental conferences, workshops and training programs.
Anyone wishing to formally serve legal documents upon the Department of Environment, Great Lakes, and Energy (EGLE), or its officers or employees, may do so by the following methods.

Union Street Dam in Traverse City. Michigan is home to more than 2,500 dams, many of which were originally built in the late 1800s and early 1900s to power mills and generate hydropower. Today, most of these structures no longer serve their original purpose and are primarily used for recreation. As these dams age, they present growing risks. Recent flooding, high water levels, and more extreme weather conditions have placed additional strain on dams across the state, reinforcing how critical ongoing maintenance, investment, and oversight have become to protecting public safety.
In recent years, Michigan has taken significant steps to address those risks. Since 2021, the state has invested $44.5 million into the Dam Risk Reduction Program, supporting 56 projects including dam removals, rehabilitation efforts, and engineering studies. That funding has allowed the Michigan Department of Environment, Great Lakes, and Energy (EGLE) and its partners to take action on some of the state’s highest-risk dams.
As funding runs dry, the need continues to grow with an estimated $1 billion required to address necessary dam infrastructure upgrades across the state. State leaders are now looking toward new solutions to sustain this work, including proposed legislation that would strengthen both funding and oversight.
House Bill 5485, introduced by Rep. Bill Schuette (R-Midland), would modernize Michigan’s dam safety system while expanding the tools needed to address aging infrastructure. The legislation would strengthen oversight, increase accountability for dam owners, and establish new funding mechanisms, including expanded grant support and a dedicated emergency response fund to help address risks before they escalate.
EGLE Director Phil Roos joined federal, state, local, and tribal leaders in Traverse City for a tour and roundtable discussion focused on dam safety program upgrades, infrastructure challenges, and proposed legislation. To highlight the progress made and the work ahead, EGLE Director Phil Roos joined federal, state, local, and tribal leaders in Traverse City for a tour and roundtable discussion focused on dam safety program upgrades, infrastructure challenges, and proposed legislation.
“Under Governor Whitmer’s leadership, we’ve made historic investments to repair and remove aging dams, helping protect communities and reduce long-term risk.” said EGLE Director Phil Roos. “We have a solid foundation in place, and now we need to strengthen our tools that support dam safety. Proposed legislation builds on that progress by modernizing oversight, increasing accountability to ensure we can better safeguard people, infrastructure and our natural resources.”
Leaders toured the Union Street Dam site along the Boardman River, the final piece of the broader Boardman-Ottaway river restoration project. Over the course of more than a decade, partners, including the Grand Traverse Band of Ottawa and Chippewa Indians, state and federal agencies, and local communities, removed three aging dams, reconnecting more than 160 miles of river and tributaries that had been fragmented for over a century. The project demonstrates how proactive investment can reduce long-term risk, improve environmental outcomes and enhance quality of life for surrounding communities
“This is an exciting project for both the Boardman/Ottaway River and the greater Traverse City community,” said Dan Zielinski, principal engineer, Great Lakes Fishery Commission. “Restoring natural fish passage while blocking invasive species will strengthen the ecosystem and fish community, making the river more vibrant and sustainable for all who depend on it.”
To wrap up the broader project, a new FishPass system will replace the Union Street Dam with a modern barrier designed to improve safety, reduce the risk of failure, and restore the river’s natural function while allowing fish to pass and preventing invasive species from moving upstream. EGLE supported the project through $1 million in funding, regulatory oversight, and technical expertise, helping ensure the aging structure was safely replaced.
“The Union Street Dam site truly gives our community a place to connect” said Benjamin Marentette, city manager for Traverse City. “Whether that’s fishing, kayaking or simply enjoying time along the river, this project creates new opportunities for people to experience and appreciate this space. At the same time, it reduces long-term risk, helping protect residents and build a more resilient community for the future.”
