By Liz Kirkwood, Executive Director, Flow Water Advocates
Michigan has lost one of its most valiant defenders and stewards.
Stanley “Skip” Pruss, husband, father, grandfather, friend, environmental attorney, clean energy expert and champion, and a cherished member of the team here at Flow Water Advocates since 2013 as senior advisor and former board chair, has passed away from cancer.
We are heartbroken to lose Skip. We send our most profound condolences to his wife Brigid, daughter Kalen, and son Emmet, grandchildren, friends, neighbors, and others who knew, loved, and benefited from their acquaintance with Skip.
Skip had a remarkable career as a public servant and public interest advocate for over 40 years. Like all of us, he endured setbacks, but he never lost hope or faith in a better outcome next time. This earnestness, Skip’s belief that facts would carry the day, and his persistence in the face of opposition, endeared him to us and inspired us.
Skip left so many lasting gifts to Michiganders, in the form of environmental victories. Here are just a few:
As an assistant attorney general, he helped negotiate the historic $172 million settlement of the Ludington Pumped Storage litigation against Consumers Energy and DTE in 1994. Through its turbine blades, the pumped storage facility was destroying 181 million fish per year, causing millions of dollars of damage to the fishery. One of the claims settled was based on the public trust doctrine. The state, led by Skip, argued that the owners of the plant should compensate the people of Michigan for damages to public trust resources.
The settlement established the Great Lakes Fishery Trust, which turned 60 miles of waterfront property owned by the utilities over to the state, and provided for public access at all DTE and Consumers Energy power plants on the Great Lakes. It also required seasonal barrier nets to minimize fish losses.
He helped then-State Senator Lana Pollack craft the 1990 “polluter pay” law, which captured more than $100 million in payments from parties that contaminated Michigan’s environment.
He was part of a successful defense of Michigan’s nationally celebrated Wetland Protection Act in 1998. He argued for the state, successfully validating the law as a tool for protection of millions of acres of wetlands.
At Flow Water Advocates, Skip was our trusted board chair, and then close advisor and colleague on clean energy, the need to shut down Enbridge Line 5 at the Straits of Mackinac, septic and water infrastructure legislation, and the value of the public trust doctrine.
In fact, in what turned out to be the culmination of his career, Skip helped put together the arguments that persuaded the Michigan Supreme Court on July 31, by a 6-1 vote, to uphold both the public trust doctrine and the Michigan Environmental Protection Act as tools in defense of the Straits and Michigan’s environment in general.
It was the public trust doctrine that provided the common ground for him and Flow. Skip firmly believed that the doctrine and the Michigan Environmental Protection Act were not just policy statements that could be ignored by private parties and state agencies at their discretion. Instead, he viewed the doctrine as a bedrock principle that imposes mandatory duties on the government to act as trustees of natural resources for the public.
In government, Skip served in many roles. Under former Governor Jennifer Granholm, he was a cabinet member and director of the Michigan Department of Energy, Labor, and Economic Growth, as well as the chief energy officer for the State of Michigan. There, he was responsible for designing and implementing Michigan’s clean energy economy and diversification efforts.
Earlier in his career, Skip served as Deputy Director of the Michigan Department of Environmental Quality. Skip was also a co-founder of 5 Lakes Energy LLC, a clean energy technology consultancy.
We gently teased Skip about his use of words like “cognate” and “internecine.” As the DNR-DEQ-EGLE retirees said in a tribute to Skip, “He was famous for working the word ‘prophylactic into many of his filings!!” As always, Skip was a good sport, laughing along with us.
Skip was also so much more:
He was a quick study on any topic, even when it waded into economics, maritime law, or oscillating wave dynamics.
He was brilliant, commanding a broad and deep understanding of law, policy, and economics.
He was encyclopedic about every subject matter he mastered. He knew statistics on renewable energy and the shift to EV cars like no one else.
He was an extraordinary mentor to us all. He was generous with his time and patient in his teachings. We all looked up to Skip for guidance, wisdom, and comfort.
Family was an even bigger part of his life. He was so proud of his kids, Kalen and Emmet. He loved his wife Brigid, a community and political leader in her own right.
Skip believed in passing the torch to young people. Through him, Flow connected with the University of Michigan School for Environment and Sustainability. He gave generously of his time and enthusiasm to counsel the students with whom Flow partnered. It delighted him when the student team produced professional-level work this year.
We are deeply saddened to say goodbye to Skip. We hope all who knew him will remember his example of courage, integrity, principle, kindness, and intelligence. If so, Skip’s light will never go out.
Friends and colleagues remember Skip Pruss.
“When I think of Skip, the words integrity, acute intelligence, kindness, loyalty and dedication come to mind. I knew him as a friend and colleague for more than 30 years. He was undaunted in pursuit of healthier policies and a healthier planet. Losing him hurts deeply. No one can replace him.”
Dave Dempsey, author and senior advisor to Flow Water Advocates
“I remember the untold hours I spent listening and learning with Skip in the run up to the polluter pay legislation. I had a sense of both purpose and privilege whenever I was working with him.”
Lana Pollack, former state senator and former US chair of the International Joint Commission
“Skip was a wonderful human being. I saw Skip champion people and the environment when I first met him in the polluter pay bill negotiations in 1990 and I’ve seen that unflagging commitment and skill in his many roles since. I was especially lucky to be able to work with him these past five years in the fight against Line 5. It is rare that someone who had such a broad influence on so many — through his leadership of government agencies, nonprofits, and lawyers — was so warm, kind and big-hearted. Skip led a life of impact, passion and humor. His passing leaves a hole in the universe and in our hearts.”
Andy Buchsbaum, former director of NWF’s Great Lakes office and co-conspirator on the Line 5 fight
“I remember meeting Skip first when he was with the Graham Administration at DELEG, with Liesl as his deputy as well as when he was at DNRE under Steve Chester and I was on the External Advisory Board (when such things existed and mattered). I was also impressed with his heart and intellect as well as strategic savvy. Working with him post-retirement with the students was a pleasure, and I’ve kept the students informed, who are also heartbroken as they could see how much he cared.”
Mike Shriberg, Director, University of Michigan Water Center
“What a breath of fresh air he was after years of management that was actively hostile to resource protection. I always appreciated Skip’s respect and deference to staff expertise. Skip was also just a pleasure to be around.”
Cathie Ballard, Chief of the Michigan Coastal Zone Management (CZM) Program
“Skip was a tenacious defender of the Great Lakes and the public trust. He took on the state’s biggest utilities to protect the Lake Michigan fishery from the Ludington Pumped Storage Plant and, later, to meet the threat posed by the Line 5 pipeline running under the Straits of Mackinac. Michigan will miss his fierce voice and unwavering devotion.”
Mark Van Putten, former President and CEO of the National Wildlife Federation and the Wege Foundation
“I was first introduced to Skip through Mark Van Putten, who handed his lawsuits over to me as he moved up the chain of command at the National Wildlife Federation’s Great Lakes office. And, as a new lawyer, one of the first environmental attorneys I met was Skip. That an assistant attorney general would meet with me, let alone coach me from time to time, was pretty humbling. But it said a lot about Skip: how committed to the public interest he was and how dedicated he was to shepherding the next generation of public interest advocates along.
In 2012, when I worked for President Obama, we organized a gathering at the White House press room about energy and the Great Lakes. I made sure Skip was on the invitation list because of his dedication, and because I knew he’d take back what he learned and apply it. Michigan and the Great Lakes are better off because of Skip.”
Cam Davis, former Obama Administration Great Lakes Sr. Advisor (2009-2017) and Commissioner, Metropolitan Water Reclamation District of Greater Chicago (2018-present)
“Saddened for the loss of Skip but buoyed by the forty years our lives interacted through his care for people, environment, and the planet. Skip was a beacon for the right thing to do. Skip’s integrity, vision, intellect and knowledge sought goodness always, and because of him we are better people, and the legal and policy principles to protect the environment, water, health, and natural resources are stronger. He lived and breathed goodness toward all and every endeavor and his goodness will continue to bless us.”
Jim Olson, environmental attorney, author, and founder of FLOW
“Personally, I feel lucky that I met Skip. I have been deeply grateful that Skip shared his political savvy and deep expertise to advance the Line 5 fight. He did so with incredible dedication and generosity of his time and knowledge.”
Debbie Chizewer, Managing Attorney at Earthjustice
