Everything You Need to Know About the EPA and DEF

Regulations put in place by the EPA are an important part of Victory Blue’s establishment as a company. This means that the EPA, including its history and current actions, is extremely important to us. We’d like to share with you the history of the EPA as well as why they are vital to the protection of the environment. The United States Environmental Protection Agency (EPA) is an agency of the U.S. federal government, which was created to protect human health and the environment by writing and enforcing regulations based on laws passed by Congress. The EPA was proposed by President Richard Nixon and began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its Administrator, who is appointed by the president and approved by Congress.



The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, tribal, and local governments. It delegates some permitting, monitoring, and enforcement responsibility to U.S. states and Native American tribes. EPA enforcement powers include fines, sanctions, and other measures. The agency also works with industries and all levels of government in a wide variety of voluntary pollution prevention programs and energy conservation efforts.

The statute that ultimately addressed this issue was the National Environmental Policy Act of 1969. Senator Henry M. Jackson proposed and helped write S 1075, the bill that eventually became the National Environmental Policy Act. President Nixon signed the law on January 1, 1970. NEPA was the first of several major environmental laws passed in the 1970s. It declared a national policy to protect the environment and created a Council on Environmental Quality (CEQ) in the Executive Office of the President. To implement the national policy, NEPA required that a detailed statement of environmental impacts be prepared for all major federal actions significantly affecting the environment. The detailed statement would ultimately be referred to as an environmental impact statement (EIS).

In 1970, President Richard Nixon proposed an executive reorganization that would consolidate many of the federal government’s environmental responsibilities under one agency, a new Environmental Protection Agency. That reorganization proposal was reviewed and passed by the House and Senate.

The EPA began regulating greenhouse gases (GHGs) from mobile and stationary sources of air pollution under the Clean Air Act (CAA) for the first time on January 2, 2011. Standards for mobile sources have been established pursuant to Section 202 of the CAA, and GHGs from stationary sources are controlled under the authority of Part C of Title I of the Act.

Manufacturers selling automobiles in the USA are required to provide EPA fuel economy test results for their vehicles and the manufacturers are not allowed to provide results from alternate sources. The fuel economy is calculated using the emissions data collected during two of the vehicle’s Clean Air Act certification tests by measuring the total volume of carbon captured from the exhaust during the tests.

Beginning with diesel engines manufactured on or after January 1, 2010, the engines are required to meet lowered NOx standards for the US market.

All of the heavy-duty engine (Class 7-8 trucks) manufacturers except for Navistar International and Caterpillar Inc. continuing to manufacture engines after this date have chosen to use Selective Catalytic Reduction technology. This Includes Detroit Diesel (DD13, DD15, and DD16 models), Cummins (ISX, ISL9, ISB6.7, and ISC8.3 line), PACCAR, and Volvo/Mack. These engines require the periodical addition of Diesel Exhaust Fluid (DEF, a urea solution) to enable the process. DEF is available in a bottle from most truck stops, and some have put in bulk DEF dispensers near the Diesel Fuel pumps. Caterpillar and Navistar had initially chosen to use Enhanced Exhaust gas recirculation (EEGR) to comply with the Environmental Protection Agency (EPA) standards, but in July 2012 Navistar announced it would be pursuing SCR technology for its engines, except on the MaxxForce 15, which was to be discontinued.

As you can see, the EPA has a large effect on environmental regulations which can lead to new technologies and businesses.
