\~ater<;iuality data before. and after BPT ~nd \VQ limitations
are. iml?oscd. This infornl<ition 'will bep;articularly important
as we near the 1977 mid-course correctiO[n since a key part of
the judgment on the desirability of more! stringent water
quality goals for 1983 and 1985 will be the observed results
of 1977-level effluent limitations.

0.' 2. Approach
303 Plans

Step 1 - States should classify all river segments
as either water quality limited or effluent guidelines limited.
An effluent guidelines limited segment would meet water quality
standards after the application of best practicable control
technology for industry and secondary treatment for municipal
plants. 1\.11 other segments are water quality limited. If
there is uncertainty on the classification of a segment, it .
should be cateqorize,d as water quality limited. Appendix A .
,provides more detailed criteria .for making the classifications'
using existing data.

plans should be submitted no later than June 3D, 1973;

Step 3 - On water quality limited segments for which
adequate data is not available to make load allocations, States
should identify resources"'and time schedules fOF obtaining the
necessary data and completing 303 plans. .
