REVISOR'S NOTE: This section is new language derived without substantive
change from former Art. 48, § 171.

In the introductory language of subsection (a)(1) of this section, the former
phrase "at any time after twelve (12) months from the date upon which the
first rules and regulations under this subtitle pertaining to new
construction and installation shall have become effective" is deleted as
obsolete because the referenced date has passed. The first regulations were
adopted October 15, 1975.

In subsections (a)(1)(i) and (2)(ii) and (c)(1) of this section, the former
reference to "rules" is deleted as included in the reference to "regulations".
See General Revisor's Note to article.

In the introductory language of subsection (c) of this section, the reference
to an "existing" boiler or pressure vessel is substituted for the former
