effective dates; manner of preparation; advice and assistance of
attorney general.

     (a) Each agency shall file in the office of the registrar
of rules a certified copy of each rule adopted by it as approved
by the governor. State agencies shall file each rule within
seventy-five (75) days of the date of agency action adopting the
rule or it is not effective. There shall be noted upon the rule
a citation of the authority by which it or any part of it was
adopted. The registrar of rules shall keep a permanent register
of the rules open to public inspection. Not more than ten (10)
days after a state agency files a copy of a rule in the office
of the registrar of rules, the agency shall mail a notice that
the rule has been filed to each person who was sent a notice
under W.S. 16-3-103(a)(i). The notice shall contain a citation
to the rule and the date it was filed. Failure to send the
notice required under this subsection does not affect the
effectiveness of the rule.
     (b) Each rule and any amendment or repeal adopted after
June 1, 1982 is effective after filing in accordance with
subsection (a) of this section and W.S. 28-9-108 except:

          (i) If a later date is required by statute or
specified in the rule, the later date is the effective date;

          (ii) Where the agency finds that an emergency exists
and the finding is concurred in by the governor, a rule or
amendment or repeal may be effective immediately upon filing
with the registrar of rules and if a state agency, also with the
legislative service office. Existing rules remain in effect
unless amended or repealed, subject to this section or W.S.
28-9-105 or 28-9-106.

     (c) Rules shall be prepared in the manner and form
prescribed by the state registrar of rules. The registrar of
rules may refuse to accept for filing any rule that does not
conform to the prescribed form.

     (d) The attorney general shall furnish advice and
assistance to all state agencies in the preparation of their
regulations, and in revising, codifying and editing existing or
new regulations.
