Under Maine regulations, fly ash, bottom ash, slag, and flue gas emission control waste generated solely from the combustion of coal, other fossil fuels, or from the combustion of coal and other fossil fuels and wood are exempt from regulation as hazardous waste so longs as the CCBs do not exhibit any characteristic for ignitability, corrosivity, reactivity, or toxicity. Under Maine regulations, coal ash is regulated as a special waste, and as such requires special handling, transportation, and disposal procedures. Reuse of CCBs is not specifically authorized under Maine law or regulations. Ash or ash-derived products may be used as a raw material substitute in concrete block manufacturing under specified circumstances.

The permit by rule requirements include maintaining records which identify the origin of the CCPs, the quantities accepted, dates of acceptance, dates of processing, and dates and locations of final disposition. The CCPs must be stored and handled in enclosed buildings or other covered areas. The beneficial use may not result in contamination to water, land or air. Notification forms must be submitted to the department at least 18 days before receiving any shipment of CCPs. Code Me. R. §6-096-409-6.
