The EPA isn't all bad.. because of the EPA we have the Clean Air Act.. because of the Clean Air Act.. we have Cleaner Air thanks in part to Ethanol.  Ever been to Beijing?  Me neither but from reports the Air quality is kind of bad over there..

The human and fiscal cost of air pollution is irrefutable. Since 2013, the World Health Organization (WHO) has tracked air quality to measure its effect on heart disease, strokes, lung cancer, and other respiratory illnesses. China and India each had 1.1 million air pollution-related deaths in 2015, accounting for half of the world’s total air pollution deaths that year.

Chinese leaders face the difficult choice of prioritizing either economic growth or environmental and social welfare. For the past several years, Beijing has a made a concerted effort to reduce high concentrations of air pollution across China.

Countries with a developed or developing industrial sector often face a tradeoff between rapid economic growth – without the constraints of environmental regulations – or public and environmental welfare measures. This challenge is not a recent phenomenon.

After the 1952 “Great Smog of London” was estimated to have killed at least 4,000 people, the UK introduced the Clean Air Act of 1956 to restrict emissions. Due to the lack of consistent data, the extent to which the act directly contributed to air-quality improvements is unknown, but the post-1960 difference was dramatic; urban concentrations of smoke fell by 80 percent and sulfur dioxide by 70 percent within 20 years.

In the United States, the Environmental Protection Agency introduced the Clean Air Act in 1970, with subsequent amendments in 1977 and 1990. The Clean Air Act established national air-quality standards, and has been associated with reductions in sulfur dioxide and other pollutants, leading to an immediate reduction in infant mortality rates. In 1972, an estimated 1,300 infants survived as a consequence of the Clean Air Act. 2 

Many Chinese citizens have expressed frustration with this public health hazard. In February 2015, Chinese reporter Chai Jing’s air-pollution documentary, “Under the Dome,” went viral upon its release. Depicting comparative interviews with environmental officials, industrial business managers, and health officials in China and Los Angeles, it received up to 200 million hits on Chinese websites such as Youku and Tencent before its removal by Internet censors. In March 2015, Peking University academics released a critical evaluation of pollution levels and current policy responses, drawing on recent U.S. Embassy data.

High pollution levels drive the demand for air quality products, including air filters and face masks. Companies such as 3M have seen a boom in air purification sales on the Chinese market since 2013. Recently this demand has pivoted toward high-end air purification units rather than cheaper alternatives. This trend has also fostered a fake goods market. In December 2015, 120,000 counterfeit masks were seized by Shanghai authorities in a raid. These masks offered no air purification, prompting public concerns over the authenticity of air quality products on the market.

So China is implementing many solutions.. including ethanol to "clean up air pollution."

The central government said last year that it plans to roll out the use of gasoline blended with 10 percent added ethanol nationally by 2020, to cut corn stocks and clean up choking smog.
