OTHER OCCUPATIONAL PERMISSIBLE LEVELS
       In the Federal Republic of Germany (FRG) as well as in
       Switzerland and Yugoslavia the TLV-TWA is 0.5 ppm (1.5 mg/cu m)
       ... In the FRG the emission of chlorine from industrial sources
       has been limited to 5 mg/cu m of waste gas. ... a WHO task
       group recommended that ambient levels of chlorine be kept below
       0.1 mg/cu m. [Seiler, H.G., H. Sigel and A. Sigel (eds.).

       Designated as a hazardous substance under section 311(b)(2)(A)
       of the Federal Water Pollution Control Act and further
       regulated by the Clean Water Act Amendments of 1977 and 1978.

CLEAN WATER ACT REQUIREMENTS
       The ambient water quality criterion for chlorine based on a
       daily water consumption of 2 l to protect human health is
       recommended to be 10.0 mg/l. [USEPA; Ambient Water Quality

CLEAN WATER ACT REQUIREMENTS
       Freshwater aquatic organisms and their uses should not be
       affected unacceptably if the 4 day average concn of total
       residual chlorine does not exceed 11 ug/l more than once every
       3 years on the average concn does not exceed 19 ug/l more than
       once every 3 years on the average. [USEPA/OWRS; Quality
