FAA Order 8260.19C, "Flight Procedures and Airspace," Paragraph 852(d)
(1):

(1) Fix altitudes established on ILS for
LOC-only use should be coincident with the glide slope
when possible. Where the fix altitude is not within
feet of the glide slope, annotate it for LOC use as
follows:

MIN ALT CAROL 1600*
*LOC only

NOTE: This notation is not used when the
nonprecision FAF altitude is the same as GS
intercept altitude.


should read "not within 20 feet..."

This is the current criteria as clarified by change 1 in 1998. It was
different before then.
