equipped with an operable marine sanitation device certified pursuant to section 312 of the Act.
(c) Letters of authorization issued
under this section are valid for 5 years,
unless sooner suspended, withdrawn, or
terminated and may be reissued upon
written request of the manufacturer to
whom the letter was issued.
(d) The Coast Guard, in accordance
with the procedure in 46 CFR 2.75, may
suspend, withdraw, or terminate any
letter of authorization issued under

the manufacture of devices labeled
under this part that are not in all material respects substantially the same
as a test device certified pursuant to
this part.

original test device.
(c) After notice under paragraph (a)
of this section, the Coast Guard notifies the manufacturer and the recognized facility in writing of any tests
that must be made for certification of
the device or for any change in the letter of authorization. The manufacturer
