(i) Best Conventional Pollutant Control Technology (BCT).
(ii) Best Available Technology Economically Achievable (BAT).
(iii) Standards of performance for new sources.
(b) A greater degree of treatment will be required to the waters where one of the following exists:
(1) The water quality of the receiving water has or is expected to improve significantly.
(2) The minimum degree of treatment required would cause pollution in downstream waters, so that designated stream uses in these downstream waters would not be achievable.
