Ethanol and Clean Air: The "Reg-Neg" Controversy and Subsequent Events

Description: The Clean Air Act Amendments (CAAA), enacted in 1990, called for cleaner automotive fuels in order to upgrade air quality. This appeared to provide new market potential for ethanol, which is obtained from corn grown in the midwestern United States, and which is already in large-scale use in a blend of ten percent ethanol to ninety percent gasoline. The CAAA left specific details of the clean fuels program to be worked out by the Environmental Protection Agency (EPA), in consultation with the interested parties.

EPA's Tier 2 Proposal for Stricter Vehicle Emission Standards: A Fact Sheet

Description: The Clean Air Act Amendments of 1990 established "Tier 1" standards to limit tailpipe emissions from new motor vehicles, and the Environmental Protection Agency (EPA) is required to determine if more stringent requirements are needed to attain or maintain National Ambient Air Quality Standards. EPA also must assess the availability and cost-effectiveness of technologies necessary to control emissions. In a report submitted to Congress in August 1998, EPA concluded that tougher standards are necessary and that essential technologies are available and cost-effective

Methane and Other Air Pollution Issues in Natural Gas Systems

Description: This report discusses the natural gas supply chain that contributes to air pollution in several ways, including (1) the leaking, venting, and combustion of natural gas in the course of production operations; and (2) the combustion of other fossil fuel resources or other emissions during associated operations.

EPA Proposes to Repeal the Clean Power Act

Description: This report discusses the EPA's proposal to repeal the Obama Administration's 2015 rule "Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Utility Generating Units (EGUs)" commonly known as the Clean Power Plan (CPP). It includes information about the legal basis for the repeal, process, possible challenges and impacts, as well as actions that Congress might take.

Methane and Other Air Pollution Issues in Natural Gas Systems

Description: This report provides information on the natural gas industry and the types and sources of air pollutants in the sector. It examines the role of the federal government in regulating these emissions, including the provisions in the Clean Air Act and other statutes, and EPA's and other agencies' regulatory activities. It concludes with a brief discussion of a number of issues under debate, including: defining the roles of industry and local, state, and federal governments; establishing comprehensive emissions data; determining the proper control of pollutants and sources; understanding the human health and environmental impacts of emissions; and estimating the costs of pollution abatement.

Reid Vapor Pressure Requirements for Ethanol

Description: This report discusses legislation (H.R. 1311, S. 517) regarding providing a waiver for ethanol-fuel blends containing greater than 10% ethanol (E15) from the Clean Air Act's (CAA) strict requirements on volatility of gasoline. This requirement currently prevents E15 gas from being sold during the summer. Major points of the legislation, various types of waivers and current rules under the CAA for gasoline and possible options for Congress are discussed.
