Section 255.552 - Notification requirements

(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).
