                      Fact  Sheet
                      Regulatory Determination  Issued
                      For Cement Kiln Dust

                        The Environmental Protection Agency (EPA) has concluded that
                     additional control of cement kiln dust (CKD) is warranted in order to protect
                     human health, and to prevent environmental damage associated with current
                     disposal practices of this waste. The Agency intends to take a "common-
                     sense" approach by developing tailored requirements that work in
                     conjunction with its existing authorities. EPA believes this approach will
                     provide adequate environmental safeguards that impose minimal economic
                     burdens on the cement manufacturing industry.

        Action
          After extensive evaluation and public involvement, EPA has decided
        that cement kiln dust requires stricter management controls.
        Consequently, the Agency plans to develop specific controls that: (1)
        prevent damage to ground and potable water and (2) reduce health
        risks associated with breathing and ingesting dust from cement kilns.
        As appropriate, EPA will use a combination of authorities to manage
        CKD. Protection against potential releases to ground water and air will
        be provided through tailor-made requirements using the Resource
        Conservation and Recovery Act (RCRA) and the Clean Air Act. The
        Agency believes that existing requirements  under the Clean Water Act
        already provide adequate control over releases to surface water.
          Until EPA promulgates new regulatory controls, cement kiln dust
        remains exempt from RCRA hazardous waste management
        requirements. This action does not affect cement kiln clinker or other
        products of cement production. Cement facilities that burn RCRA
        hazardous waste in their kilns still must test their dust to  see that it
        remains unaffected by the combustion of hazardous  waste. Dust that is
        affected by combustion must be managed according  to appropriate
        RCRA regulations.

        Background
         When Congress developed legislation governing the disposal of
        hazardous waste, it identified six categories of wastes that  were
       believed to pose less risk to human health and the environment. These

-------
"special" wastes— known as Bevill wastes—were exempt from RCRA
Subtitle C requirements, pending studies and regulatory
determinations by the Agency. One of the Bevill wastes, cement kiln
dust is very fine particulate material that is carried out by gases exiting
the cement kiln during burning, and collected in air pollution control
devices. This action on CKD is the last regulatory determination
required for the special Bevill wastes.
