## Northern Natural Gas Overview

***Northern’s Pipeline System:***
- Approximately 15,700 miles of high pressure, natural gas transmission pipeline operating in portions of eleven Midwestern states.
- Steel pipe sizes range from 2” to 36” in diameter
- Maximum operating pressure ranges from 50 to 1,600 psig
- The system is divided into four operating regions
- Each region is managed by one director and several operations managers

## Northern’s Pipeline System

##  1162 Clearinghouse Review

*Review results and actions*
- The clearinghouse review results indicated the need for Northern to clarify the supplemental enhancement section.
- Northern partnered with our local PHMSA/CATS representative to discuss ideas, options, expectations and deadlines.
- Northern submitted the adjustments to the CATS representative and received approval to move forward with a new supplemental enhancement table that will be added to our procedures.

##  Supplemental Enhancement Table

| Factors | Action Level Examples | Enhancement Response Options |  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
|  |  | Expanded Corridor For Brochure Delivery  | Brochure Message Enhancement | Media Campaign | Additional Mailings | Increased Surveillance | Door Hangers | Personal Contact | Extra Signs |
| Land Development | New Construction |  |  |  |  |  |  |  |  |
| Farming Activity Deeper Than Typical Farming Practices | Discovery of Terracing, Waterways, Drain tile. |  |  |  |  |  |  |  |  |
| Third Party Damages | Incident Increase |  |  |  |  |  |  |  |  |

**Notes:**
Northern’s procedure lists 15 factors, most of which come directly from 1162 but pipeline operators are allowed to add factors that address specific conditions on their pipeline.

## Supplemental Enhancement Process

- As I mentioned earlier, Northern’s field locations are supervised by operations managers
- Each operations manager will take part in a review of their public awareness activity. The review will be completed at least annually or upon discovery of a new or changed condition
- The review helps to document actions taken, new conditions discovered, suggestions for improvement and a discussion of each of the supplemental enhancement factors
- If a supplemental enhancement factor and an action level are taking place in the operations manager’s area of responsibility they report current response actions or determine if additional actions are required
- Their responses are marked with an “X” in the appropriate Enhancement Response Option column

##  Example – Land Development 

- Operations managers understand that whenever a factor is discovered, action must be taken
- Case in point, during a one-call response an employee is alerted to the beginning phases of a new building that will be constructed near Northern's pipeline
- The operations manager works with the field employees to determine the next steps
- The enhancement response options provide the template for action
- For example, the operations manager will more than likely decide that several boxes need to be checked. Which translates to several actions that will take place
- In this case, it makes good sense to include increased surveillance activity, personal contact and extra signs
- Northern’s overall program already includes an expanded corridor for public awareness brochure delivery so this box could be checked also
