PART 192--HEALTH AND ENVIRONMENTAL PROTECTION STANDARDS FOR URANIUM AND THORIUM 
MILL TAILINGS--Table of Contents
 
 Subpart A--Standards for the Control of Residual Radioactive Materials 
                 from Inactive Uranium Processing Sites
 
Sec. 192.01  Definitions.

    (a) Residual radioactive material means:
    (1) Waste (which the Secretary determines to be radioactive) in the 
form of tailings resulting from the processing of ores for the 
extraction of uranium and other valuable constituents of the ores; and
    (2) Other wastes (which the Secretary determines to be radioactive) 
at a processing site which relate to such processing, including any 
residual stock of unprocessed ores or low-grade materials.
    (b) Remedial action means any action performed under section 108 of 
the Act.
    (c) Control means any remedial action intended to stabilize, inhibit 
future misuse of, or reduce emissions or effluents from residual 
radioactive materials.
    (d) Disposal site means the region within the smallest perimeter of 
residual radioactive material (excluding cover materials) following 
completion of control activities.
    (e) Depository site means a site (other than a processing site) 
selected under Section 104(b) or 105(b) of the Act.
    (f) Curie (Ci) means the amount of radioactive material that 
produces 37 billion nuclear transformation per second. One picocurie 
(pCi) = 10 -12 Ci.
    (g) Act means the Uranium Mill Tailings Radiation Control Act of 
1978, as amended.
    (h) Administrator means the Administrator of the Environmental 
Protection Agency.
    (i) Secretary means the Secretary of Energy.
    (j) Commission means the Nuclear Regulatory Commission.

    (2) Any other real property or improvement thereon which is in the 
vicinity of such site, and is determined by the Secretary, in 
consultation with the Commission, to be contaminated with residual 
radioactive materials derived from such site.
    (m) Tailings means the remaining portion of a metal-bearing ore 
after some or all of such metal, such as uranium, has been extracted.
    (n) Disposal period means the period of time beginning March 7, 1983 
and ending with the completion of all subpart A requirements specified 
under a plan for remedial action except those specified in Sec. 192.03 
and Sec. 192.04.
    (o) Plan for remedial action means a written plan (or plans) for 
disposal and cleanup of residual radioactive materials associated with a 
processing site that incorporates the results of site characterization 
studies, environmental assessments or impact statements, and engineering 
assessments so as to satisfy the requirements of subparts A and B of 
this part. The plan(s) shall be developed in accordance with the 
provisions of Section 108(a) of the Act with the concurrence of the 
Commission and in consultation, as appropriate, with the Indian Tribe 
and the Secretary of Interior.
    (p) Post-disposal period means the period of time beginning 
immediately after the disposal period and ending at

termination of the monitoring period established under Sec. 192.03.
    (q) Groundwater means water below the ground surface in a zone of 
saturation.
    (r) Underground source of drinking water means an aquifer or its 
portion:
    (1)(i) Which supplies any public water system as defined in 
Sec. 141.2 of this chapter; or
    (ii) Which contains a sufficient quantity of groundwater to supply a 
public water system; and
    (A) Currently supplies drinking water for human consumption; or
    (B) Contains fewer than 10,000 mg/l total dissolved solids; and
    (2) Which is not an exempted aquifer as defined in Sec. 144.7 of 
this chapter.
