Section 366.303  B2 Factor (Water Quality)

B2 is a factor that evaluates the existing quality of the receiving stream in accordance with the procedure outlined in A2, and modifies that ranking so as not to encourage additional waste load to high quality streams.  The B2 factor is calculated by multiplying the Water Quality Factor as calculated in A2 by the high quality water factor for the stream class (see Appendix A):

0.60 for A streams (Unique Aquatic Resource);

0.75 for B streams (Highly Valued Aquatic Resource);

1.00 for C streams (Moderate Aquatic Resource);

1.00 for D Streams (Limited Aquatic Resource);

1.00 for E streams (Restricted Aquatic Resource).
