Oklahoma regulations adopt by reference the federal regulation that exempts CCBs (including fly ash, bottom ash, slag, and flue gas emission control waste generated primarily from the combustion of coal) from classification as hazardous waste. Reuse of CCBs is not specifically authorized under Oklahoma law. CCBs are exempt from solid waste regulations if constructively reutilized in approved mine applications. Note: Fly ash and bottom ash generated outside the state must be constructively reutilized or disposed only in active or inactive mining operations subject to state laws and regulations.

Detailed Review of CCB Regulations:
Oklahoma regulations adopt by reference the federal regulation which exempts CCPs from classification as hazardous waste. Exempt from hazardous waste regulation are fly ash, bottom ash, slag and flue gas emission control waste generated primarily from the combustion of coal. OAK. REG. 252:205-3-2(c); 40 CFR 261.4.

According to a February 29, 2000, CCP Policy Statement, the Oklahoma Department of Environmental Quality currently allows the following uses of CCPs without prior approval when used according to the applicable standard (generally ASTM): cementious material production, daily landfill cover (with permit modification), as manufactured product, road base, road surfacing material, solidification/chemical fixation, deicing, soil stabilization, subgrade treatment, engineering applications and mine reclamation. Records of reuse and disposal of CCPs must be kept and storage shall be in an environmentally appropriate manner to prevent releases to the environment.

Note: Fly ash and bottom ash over 200 tons and generated outside the state must be constructively reutilized or disposed only in active or inactive mining operations subject to state laws and regulations. OKLA. STAT. 27A §2-10-801(F). CCPs are exempt from solid waste regulations if constructively reutilized in approved mine applications. OKLA. STAT. 45-12- §940.
