RE: Application of 1/2 FAV Calculation to the Subject
Sites
Joe has revised Maximum Daily Load effluent limits for only those parameters where
values increased (i.e. became less stringent) applying the latest 1/2 FAV calculations (see
Sue Wilson's memo dated January 2, 2000). Because this was "a minor mod at the
request of the permittee for revision of cyanide only," parameter values that would have
become more stringent, were not upgraded (per Dave Goodrich).
Therefore upon renewal of these permits, the next permit writer must
upgrade the other Daily Maximum parameters to the latest calculations.
