(a) The
					 maximum allowable operating pressure of any transmission line, or main
					 operating at a pressure of 125 psig (862 kPa) or above, shall not be raised or
					 lowered without submitting a letter of intent at least 60 days prior to any
					 proposed change of said certified operating pressure. Where the letter of
					 intent indicates a decrease in the maximum allowable operating pressure, a
					 statement of explanation is to be included. All procedures involved in the
					 recertification project shall be in accordance with these requirements. In the
					 event of an emergency, verbal permission may be obtained, but the written
					 application must be filed promptly.
(b) In addition, any operator proposing to
					 increase the maximum allowable operating pressure of a pipeline which was
					 originally constructed to operate at a pressure of less than 125 psig (862 kPa)
					 to a pressure of 125 psig (862 kPa) or more shall comply with the reporting
					 requirement of subdivision (a) of this section. If the increase in pressure is
					 proposed within three years of the initial operation of a pipeline which, at
					 the higher pressure proposed, would fall within the definition of major utility
					 transmission facility as set forth in section 120 (2)  of the Public
					 Service Law, a hearing will be held on the proposed increase, unless such
					 hearing is waived by the commission on the application of staff of the
					 department. In addition with respect to any such increase, the operator shall,
					 in addition to the reporting requirements set forth above, provide in writing
					 to staff the basis of the need for the increase, a discussion of how the
					 increase will serve the public interest, convenience and necessity, and such
					 assurance as staff may require, including documentation, that no undue hazard
					 will result from operation of the line at the higher pressure.
(c) At least 60 days prior to increasing the
					 maximum allowable operating pressure of a distribution system above the limits
					 set below, the operator shall submit a letter of intent. In the event of an
					 emergency, verbal permission may be obtained, but the written notification must
					 be filed promptly.
(1) If the maximum
					 allowable operating pressure is between 1/2 psig (3.4 kPa) and 60 psig (414
					 kPa), notice is required for an increase in pressure greater than six psig
					 (41.4 kPa).
(2) If the maximum
					 allowable operating pressure is between 60 psig (414 kPa) and 124 psig (855
					 kPa), notice is required for an increase in pressure greater than 10 percent of
					 the maximum allowable operating pressure.
(3) Converting a low pressure distribution
					 system to a high-pressure system not to exceed 124 psig (855 kPa).

(a) The
					 pressure must be increased gradually, at a rate that can be
					 controlled.
(b) Prior to the first
					 pressure increase and at the end of each incremental increase, the pressure
					 must be held constant while the entire segment of the pipeline that is affected
					 is leakage surveyed.
(c) Each
					 hazardous leak detected must be repaired before a further pressure increase is
					 made. All leaks must be repaired as soon as possible following completion of
					 the upgrading.
(d) Each operator
					 who upgrades a segment of pipeline shall retain for the life of the segment a
					 record of each investigation required by this Part, of all work performed, and
					 of each pressure test conducted, in connection with the upgrading.
(e) Each operator who upgrades a segment of
					 pipeline shall establish a written procedure that will ensure compliance with
					 each applicable requirement of this Part.
(f) Except as provided in section
					 255.555(c) 
					 of this Part, the new maximum allowable operating pressure may not exceed the
					 maximum that would be allowed under sections
					 255.619
					 and
					 255.621 
					 of this Part for a new segment of pipeline constructed of the same materials in
					 the same location. However, when uprating a steel pipeline, if any variable
					 necessary to determine the design pressure under the design formula (section
					 255.105 
					 of this Part) is unknown, the MAOP may be increased as provided in section
					 255.619(a)(1) 
					 of this Part.
