Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is a psychoactive drug, best known as the type of alcohol found in alcoholic beverages and in modern thermometers. Ethanol is one of the oldest recreational drugs. In common usage, it is often referred to simply as alcohol or spirits.

Methanol is mixed with Ethyl Alcohol to make it Ethanol for use as a fuel. Grain Alcohol is just that, simple Ethyl alcohol.

Methanol, also known as methyl alcohol, carbinol, wood alcohol, wood naphtha or wood spirits, is a toxic chemical with chemical formula CH3OH (often abbreviated MeOH). Drinking even small amounts can cause blindness. It is the simplest alcohol, and is a light, volatile, colourless, flammable, toxic liquid with a distinctive odor that is very similar but slightly sweeter than ethanol (drinking alcohol).

In order for Everclear to be classified as Ethanol, it has to contain Methanol. Everclear is a grain alcohol, not Ethanol.�

Alcohols can be used as a beverage (ethanol only), as fuel and for many scientific, medical, and industrial utilities. Ethanol in the form of alcoholic beverages has been consumed by humans since pre-historic times. A 50% v/v solution of ethylene glycol in water is commonly used as an antifreeze.

Some alcohols, mainly ethanol and methanol, can be used as an alcohol fuel.

You are encouraged to review the gasoline volatility regulations Title 40 Code of Federal Regulations Part 80 with your attorney to understand your compliance obligations.

If you or your carrier splash-blend ethanol and gasoline, the RVP regulations provide a 1 psi waiver for ethanol blends provided that:

1. the base gasoline meets the applicable RVP standard;
2. the blend contains between 9 and 10 percent ethanol by volume, excluding the denaturing agent; and
3. no additional alcohol or other additive or component has been added to increase the volatility of the ethanol portion of the blend.

If ethanol-blended gasoline is mixed with straight gasoline during the RVP control season and the ethanol content of the mixture drops below 9 percent, you will lose the 1 psi waiver.. Since it takes less than four percent ethanol to add a full 1 psi to the vapor pressure, the absence of the waiver would cause this product to violate the RVP standard.

Violations of the gasoline RVP regulations are subject to fines under the U.S. Clean Air Act of up to $37,500 per day of violation, plus any economic benefit derived from the violation. If the EPA finds a violation at any point in the gasoline distribution network, there is a regulatory “presumption” of liability for that party and all parties upstream of where the violation was found

Michigan 7.0 RVP (Detroit area)

The state of Michigan has implemented a low vapor pressure program where gasoline with a maximum RVP of 7.0 psi is required from June 1 through September 15. Federal RFG is a complying substitute for the 7.0 RVP under Michigan regulations. The covered area is the Detroit metro area. (See Attachment I.)
