Changes to Regulation I, Section 6.03 (Notice of Construction):

Article 6 amendments provide a technical clarification in the Notice of Construction (NOC) exemption list found in Section 6.03(c) regarding metal cutting.  The amendments move the exemption criteria that relate to thermal cutting to the metallurgy section of the exemptions and amend the material handling section for mechanical processes (e.g. cutting, sanding, etc.).  The change requires thermal cutting of stainless steel installed after November 1, 2013 to be subject to NOC review.  The change exempts thermal cutting of metal alloys that are not classified as stainless steel.  It also exempts thermal cutting of any metal (including stainless) if it is incidental to plant maintenance activities.
