On Feb. 26, the Environmental Quality Board (EQB) took another meaningful step toward finalizing Pennsylvania’s first state-established maximum contaminant levels (MCLs) for regulating contaminants in drinking water. On that date, the EQB published a proposed rule to amend 25 Pa. Code Ch. 109 (Safe Drinking Water) to establish MCLs for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), two of the most common PFAS. PFOA and PFOS are just two of a group of thousands of PFAS, manmade chemicals used in various consumer, commercial and industrial manufacturing processes since the 1940s. PFAS have commonly been used to imbue products with water-, stain-, and heat-resistant properties and as ingredients in aqueous film forming foams (AFFF) used to extinguish flammable liquid fires (e.g., those that might occur on airports or military bases). PFAS do not break down naturally in the environment and have thus been called “forever chemicals.” Due to these properties and their ubiquitous nature, PFAS have been found in various environmental media, such as groundwater (including drinking water), plants, animals, and in humans, and evidence suggests that PFAS exposure can lead to adverse health effects. In the absence of definitive federal action to regulate PFAS, many states, including Pennsylvania, have in recent years taken steps to investigate, understand, and regulate PFAS.
Pennsylvania’s proposed rule is the result of years of investigation and evaluation. In 2018, Gov. Tom Wolf established by executive order (2018-08) Pennsylvania’s PFAS action team, which he tasked with the broad functions of, among other things, ensuring safe drinking water and managing environmental PFAS contamination. In June 2019, the Pennsylvania Department of Environmental Protection (PADEP) began sampling public drinking water systems within a half mile of potential PFAS sources such as manufacturing, fire training and military facilities. …
While long term goals of lowering greenhouse gas emissions and employing sustainable energy sources have gained momentum across all industries, Chevron Corp., through its New Energies division, has stated it has shorter term goals as well – it says its planned growth in renewable fuels, hydrogen and carbon capture is expected to enable about 30 million tones of annual CO2 equivalent emission reductions by 2028. Technology adoption, policy and consumer behavior will drive energy choices, says a top sustainability executive, as companies focus on carbon management along the path to net zero. All three factor into whether one form of energy or another is sought to supply demand created by income and population growth, according to Bruce Niemeyer, vice president of strategy and sustainability for Chevron Corp. “Keeping supply and demand balanced through the transition is important so the transition works for all and doesn’t become a negative event for those most vulnerable,” Niemeyer said earlier this month during UT Energy Week. He added, “We’re going to need many forms of energy, which means we need to work on reducing the carbon intensity of all of them.” Chevron is among the many companies working to lower its emissions amid a heightened focus on global warming and future energy supplies. Like the smartphone, technologies with features that meet consumers’ needs or low-cost technologies will gain market share, he said, noting consumer preference is a strong factor. Take, for example, the automotive sector. EVs are expected to play a key role in the energy transition, giving their lower emissions, compared to vehicles with internal combustion engines. However, “last year, our best estimate is there were 6.6 million electric vehicles sold. At the same time, there were 35 million SUVs.
