EPA Unveils Its PFAS Action Plan: What You Need to Know

EPA Unveils Its PFAS Action Plan: What You Need to KnowThe EPA recently launched its Action Plan for per- and polyfluoroalkyl substances (PFAS). PFAS are a large class of manufactured chemicals that are very effective in several industrial applications, but have also posed risks to human health through drinking water sources around the United States.

The Action Plan mainly uses the Safe Drinking Water Act (SDWA) to address the dangers of PFAS. The agency said it considered 120,000 public comments on what the Action Plan should include and how it should be implemented.

“It took groundbreaking efforts to develop this plan,” EPA Acting Administrator Andrew Wheeler said. “This is the first time we have utilized all of our program offices to deal with an emerging chemical of concern. It is the first time we have put together a multi-media, multi-program national research and risk communication plan to address a challenge like PFAS.”

The EPA said it will also start researching whether at least some of these chemicals should be regulated under other laws, such as the Toxic Substances Control Act (TSCA), Superfund, and the Emergency Planning and Community Right-to-Know Act (EPCRA).

The Risks of PFAS

PFAS were introduced in the 1940s and have several applications, including providing fabrics with stain and water resistance and giving nonstick properties to cookware. The durability of PFAS that has made it a desirable chemical contributes to its abundance in the environment and human body. Two PFAS, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), can cause cancer and reproductive, developmental, kidney, liver and immunological effects (PFOA) and thyroid hormone disruption (PFOS) in laboratory animals.

Although it can occur in multiple ways, including through soil and food consumption, the biggest concern of PFAS is its presence in drinking water. That’s why the primary goal of the Action Plan is to “initiate steps to evaluate the need for maximum contaminant levels (MCLs) for PFOA and PFOS.”

Implementing the PFAS Action Plan

The finalization of MCLs for PFOA and PFOS can take from five to 10 years. It could be several years after that before drinking water systems would be mandated to meet the MCL.

Some U.S. manufacturers voluntarily phased out production of PFOA and PFOS starting in 2000.

Other long-term actions under the EPA’s plan, which will take more than two years to implement, include:

  • Taking steps to propose classifying PFOA and PFOS as hazardous substances through federal statutory mechanisms, such as the Conservation and Recovery Act (RCRA), TSCA and EPCRA.
  • Establishing groundwater cleanup recommendations for PFOA and PFOS at contaminated sites.
  • Creating toxicity values or oral reference doses (RfDs) for GenX chemicals (hexafluoropropylene oxide (HFPO) dimer acid and its ammonium salt) and perfluorobutane sulfonic acid (PFBS).

Short-term actions under the plan include:

  • Establishing analytical methods and tools for understanding and controlling PFAS risk.
  • Developing Significant New Use Rules (SNURs) under TSCA, which require EPA notification before chemicals are utilized in new ways that could result in human health and ecological concerns.
  • Taking enforcement steps to help manage PFAS risk.

Reactions From the Industry

The industry is generally optimistic about the EPA’s new Action Plan. 3M, which introduced PFOS chemicals in the 1940s and took part in the phaseout in 2000, said that it welcomed the plan.

“We support regulation rooted in the best-available science and believe that this plan may help prevent a patchwork of state standards that could increase confusion,” 3M said in a statement.

However, some environmental groups think the Action Plan provides little action and is mainly for show.

“EPA has been promising to address the serious public health threat posed by PFAS chemical exposures for almost twenty years,” Rob Bilott, an attorney who has represented clients with PFAS claims, said in a statement released by the Environmental Working Group. “The last ‘action plan’ was released a decade ago—in 2009. Unfortunately, despite the promising public relations messaging released in connection with EPA’s latest PFAS ‘Action Plan,’ EPA is still not actually taking any concrete action on PFAS.”
