Waters of the United States

The Obama administration’s “Clean Water Rule” was designed to control pollution in approximately 60% of the country’s bodies of water. The Rule primarily extended current federal regulations to smaller bodies of water, requiring that pollution of rivers and wetlands be held to the same environmental penalties as larger bodies of water. However, the Trump administration has suspended enforcement of the regulation for two years. During that time, they will re-consider the definition of “waters of the United States.” The Trump administration intends to release a new version this year.

Once In, Always In

The Environmental Protection Agency (“EPA”) recently issued a guidance memorandum withdrawing the decades-old “once in, always in” policy. The policy prohibited facilities once considered to be major sources of emissions of hazardous air pollutants to be later reclassified. These facilities are always subject to the class Maximum Achievable Control Technology (“MACT”) standards, regardless of any newly implemented processes or controls that reduce emissions.

However, the EPA found that the policy was established upon an incorrect interpretation of the Clean Air Act. Facilities may now be reclassified as “area sources” if their emissions fall below the threshold and will be subject to less strict standards.

Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium-Duty and Heavy-Duty Vehicles

Under the Obama Administration, the EPA passed Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium-Duty and Heavy-Duty Vehicles. The regulation aimed to reduce climate change-causing emissions from the transportation sector, particularly the pollution caused by trucks. However, following the voiced concerns of stakeholders in the glider and trailer industry, the Trump Administration has issued a notice of repeal of emission requirements for glider vehicles, glider engines, and glider kits.

The EPA’s Smart Sectors Program

In October 2017, the Environmental Protection Agency (“EPA”) launched the Smart Sectors Program, a program that creates a collaborative partnership between the EPA and regulated sectors such as the automotive, agriculture, and mining industries. The program provides a platform for the EPA and regulated sectors to collectively develop approaches to protect the environment, public health, and the economy.

Coal Ash Regulation

Power plants generate a residue after burning coal called coal ash, more formally known as coal combustion residuals (CCRs). In October 2015, the Environmental Protection Agency (EPA) established national guidelines to address the environmental dangers and health risks of coal ash. In May, nearly two years after the rule regulating the disposal of CCRs from electric utilities came into effect, industry officials petitioned the EPA to reconsider the rule, claiming adverse effects.
