Guidance on Determining High Consequence Areas and on Carrying out Requirements in the Integrity Management Rule
I. Guidance on Determining a High Consequence Area
To determine which segments of an operator's transmission pipeline system are covered for purposes of the integrity management program requirements, an operator must identify the high consequence areas. An operator must use the methods defined in paragraphs (1) or (2) of subdivision (f) of section 255.903 of this Part to identify a high consequence area. An operator may apply one method to its entire pipeline system, or an operator may apply one method to individual portions of the pipeline system. (Refer to Figure 1 below for a diagram of a high consequence area.)

II. Guidance on Assessment Methods and Additional Preventive and Mitigative Measures for Transmission Pipelines
(a) Table 1 below gives guidance to help an operator implement requirements on additional preventive and mitigative measures for addressing time dependent and independent threats for a transmission pipeline operating below 30 percent SMYS not in a High Consequence Area (i.e., outside of potential impact circle) but located within a Class 3 or Class 4 Location.
(b) Table 2 below gives guidance to help an operator implement requirements on assessment methods for addressing time dependent and independent threats for a transmission pipeline in a high consequence area.
(c) Table 3 below gives guidance on preventive and mitigative measures addressing time dependent and independent threats for transmission pipelines that operate below 30 percent SMYS, in high consequence areas.

Results are to be utilized as part of an overall evaluation of the CP system and corrosion threat for the covered segment. Evaluation shall include consideration of leak repair and inspection records, corrosion monitoring records. exposed pipe inspection records, and the pipeline environment. For Unprotected Transmission Pipelines or Cathodicallv Protected pipe where Electrical Surveys are Impracticable: • Conduct Quarterly leak surveys AND • Every 1½ years, determine areas of active corrosion by evaluation of leak repair and inspection records. corrosion monitoring records, exposed pipe inspection records, and the pipeline environment.
