(2) The purpose of a permit is to provide notice to the Division that an employer will undertake permit-required activity and to allow the Division an effective means of ensuring that the proposed permit-required activity will be performed safely.
(3) There are two types of permits: Project Permits and Annual Permits. Both types are defined below in subsection (b) and explained in subsections (c), (d), and (e).
(4) The Permit application process is explained in section 341.1.

(3) “Conduct permit-required activity” means either:
