[Hint:  To locate an individual final rule, open the appropriate

ERC book and see the Historical Note at the end of each Section to find the month and year of a change.  Then go to the Monthly Regulation Changes page and look for the year and then month that corresponds with the Historical Note.  Look for the word "final" in the Status column.  (Final "OS" rules on or before October 20, 2006, may include final rules in your search.  The "MM" rules include multiple Parts of the ERC and may include a final rule in your search.)  The ERC Quarterly Supplements contain final rules that do not include strikeout/underline formatting and are appropriate for printing a clean copy of the entire final rule.  Final rules are published in the Louisiana Register.  For assistance, call the Regulation Development Section at (225) 219-3981.]
