Can Ethanol (Ethyl Alcohol) Industrial wastestream discharges to the collection system be controled with a BOD limit or will a separate Ethanol limit need to be established?

Also can Methanol (Methyl Alcohol), a hazardous waste when discharged to the sanitary sewer, be discharged at any level without negatively impacting the wastewater treatment plant?

Quote from the Methanol Institute: Product grade methanol, when disposed, is a listed hazardous waste. Waste methanol, or water contaminated with methanol, is considered a hazardous waste and must never be discharged directly into sewers or surface waters.
