the vessel is provisionally certified providing the department does not invalidate the certification
by issuing disapproval within 45 days after receipt of the results.
(5) There must be no visible liquid leaks from the vessel or collection system, except when the
disconnection of dry breaks in liquid lines produces a few drops of liquid.

Leaks must be detected by a combustible gas detector using the test procedure described in R

(8) There must be no visible leaks, except from the disconnection of bottom loading dry breaks

and location of the test, test procedures, the type of equipment used, and the results of the test must
be submitted to the department within 60 days following the last date of the test. If the time or
location of the test changes for any reason, then the owner or operator shall notify the department
as soon as practical.
