In Waukegan, Illinois, about 40 miles north of Chicago, Dulce Ortiz is celebrating with her children.

Ortiz is a co-founder of the local environmental justice organisation Clean Power Lake County. She has been organising for years to get coal ash waste cleaned up from the site of the retired coal power plant in her town.

The historic suite of power plant pollution standards announced last week by the Environmental Protection Agency (EPA) includes a rule that will finally force power plant owners to clean up their coal ash pollution.

This is good news for Dulce Ortiz’s family and countless others, including the 30 million people who get their drinking water from the Great Lakes. Coal ash contains toxic pollutants like mercury, arsenic, and cancer-causing polychlorinated biphenyls (PCBs) that leach into groundwater. And there are more than 100 coal ash waste sites along the shores of the Great Lakes. This includes legacy sites from retired plants like the one in Waukegan, which left two coal ash ponds and another coal ash deposit.

Ortiz says, “My vision for my family and my community is a lakefront where I can take my children swimming in the waters of Lake Michigan without worrying about toxic pollution; where we can go fishing without worrying about mercury and PCB contamination of the fish we catch; where I can go running along the shores of Lake Michigan without worrying about air pollution triggering my asthma. I want to see a clean energy future for Waukegan and all communities that have borne the burden of coal and industrial plant pollution for decades.”

Waukegan has borne a particularly heavy burden. The predominantly black and brown residents share their town with five of Illinois’ 11 Superfund hazardous waste sites. That does not include the coal ash deposits.

Toxic waste from coal and industrial plants has been a plague for many American communities like Waukegan. One of my mentors, a legendary community organiser in Pittsburgh, once showed me an uncovered coal ash pit there. I asked him where all that waste went when there was a heavy rain. I still remember his response: “Nowhere good.”

In addition to addressing coal ash, the new EPA rules also include vital new standards for carbon and other toxic pollutants pumped into our air and water by coal- and gas-burning power plants. The impact of these rules in cutting carbon dioxide (CO2) from power plants — one of the top greenhouse gas contributors — will be to accelerate the decline of carbon emissions and our transition to clean energy. And, of course, these pollution standards mark a tremendous stride for public health that will save lives and prevent chronic illnesses.

The rules will remove economic barriers for some American communities that need it the most.

The new suite of EPA rules is a critical moment in the fight for a clean energy future and the result of years of advocacy. These common sense safeguards mark the beginning of our next chapter in the fight to transition to a 100 per cent clean energy economy. And, remarkably, they are the latest in a string of groundbreaking actions by the Joe Biden- Kamala Harris Administration announced throughout April, which is Earth Month.

The Bureau of Land Management issued a new federal rule making conservation a priority on our majestic public lands. The Department of the Interior announced new protections for 13 million acres of land in the Western Arctica from oil drilling. That is just to name a couple. What a way to celebrate Earth Month!

We all deserve a cleaner, healthier future. And the Biden-Harris Administration just delivered in a way that is going to help get us there faster.
