476.4 - TARIFFS FILED.

        476.4  TARIFFS FILED.         Every public utility shall file with the board tariffs showing the      rates and charges for its public utility services and the rules and      regulations under which such services were furnished, on April 1,      1963, which rates and charges shall be subject to investigation by      the board as provided in section 476.3, and upon such investigation      the burden of establishing the reasonableness of such rates and      charges shall be upon the public utility filing the same.  These      filings shall be made under such rules as the board may prescribe      within such time and in such form as the board may designate.  In      prescribing rules and regulations with respect to the form of      tariffs, the board shall, in the case of public utilities subject to      regulation by any federal agency, give due regard to any      corresponding rules and regulations of such federal agency, to the      end that unnecessary duplication of effort and expense may be avoided      so far as reasonably possible.  Each public utility shall keep copies      of its tariffs open to public inspection under such rules as the      board may prescribe.         Every rate, charge, rule and regulation contained in any filing      made with the commission on or prior to July 4, 1963, shall be      effective as of such date, subject, however, to investigation as      herein provided.  If any such filing is made prior to the time the      commission prescribes rules as aforesaid, and if such filing does not      comply as to form or substance with such rules, then the public      utility which filed the same shall within a reasonable time after the      adoption of such rules make a new filing or filings complying with      such rules, which new filing or filings shall be deemed effective as      of July 4, 1963.
