I was getting what I wanted; i.e., the two rules that spanned the textwidth' of the page.

I tried your \noindent advice and that made no difference --- no difference in the sense that the PDF seems unchanged and the warning' command remains as noted above. Here is my wild guess as to what is going on!

The document class line is

\documentclass [11pt, fleqn, leqno] {book}

and shortly is followed by

\usepackage[parfill]{parskip}  % Begin paragraphs without indent of the first word

So, it seems that "my paragraph indent" should be zero!

Also, the geometry' package has been used to changed the text area as follows:

\usepackage{geometry}       % See geometry.pdf (\$:texdoc geometry)to learn the layout options.
\geometry{letterpaper}        % Set paper size to 8.5''x11''. This is the default for <book>
\geometry{includeheadfoot}	% include header & footer as part of body (text area)
\geometry{top=0.75in, bottom=0.5in}	% textheight = 11 - .75 - .5 = 9.75 in
\geometry{inner=1in, outer=1.5in}	% textwidth = 8.5 - 1 - 1.5 = 6 in

So is it possible that the warning about the rules being "(30.0pt too wide)" is based on the default values for {book} and not the ones that I've changed with \geometry ??? Just guessing! 30pt off is a large error!
