Not sure if anything will come of it but we are pushing back
aggressively about the casual way this requirement came about (look
for my comment when the ROC is published). Instead of ignoring the
fact that the methodology is anything but academically pure, we say
assign a reduced factor (or an AF multiplier) to reflect an averaged
reasonable difference and stay with the good ole Hazen-Williams
equation. Otherwise we are simply picking the fly sh.. out of the
pepper!!!
IN case the angry mob finds me, does anyone have a painless way for
removing tar and feathers?
