General The Company will not approve a Residential application for service until the Applicant(s) has established satisfactory credit or otherwise provided sufficient security, as described in this General Rule 2. For purposes of this General Rule, sufficient security is either (a) a cash deposit, or (b) a written surety agreement from a qualifying person, the specifics of each are set forth in General Rule 6 and 6A of this Tariff. The establishment of credit or the Company s acceptance of other security under this General Rule shall not relieve a Residential Applicant or Customer from complying with the Rules and Regulations established by the Commission, including but not limited to, the prompt payment of bills and the Disconnection of Service for nonpayment. For purposes of establishing credit, a builder, contractor, property developer, or property manager shall be considered a Non-Residential Applicant on any application made for gas service to real property for which they are responsible through their business activities, whether the property to which the application for service applies is classified as Residential or Non-Residential. A Residential Applicant that is required to pay a deposit, or that provides a surety agreement in lieu of a deposit, will be deemed to have established credit when they have maintained an active account with the Company for one Year, and during such Year: (a) Customer did not receive more than two final notices of disconnection (also known as a 5-day notice), and (b) Customer was not disconnected for non-payment, theft, diversion of service, or for tampering with utility facilities.

In the event that there are multiple active accounts but no single account has been active for a consecutive 12-month period, then the requirement for 12-months of continuous service may be met by combining the non-duplicative active months across all accounts (i.e. account #1 was active January- May; Account #2 was active April through December). If the consecutive 12-month period cannot be met (i.e. the accounts were all activated less than 12 months and for the same calendar months), then a (continue to Sheet RR-2.1) Issued October 19, 2010 NWN Advice No. OPUC and after November 24, 2010

During the prior 24 months, Applicant did not have service disconnected for nonpayment, for theft or diversion of service, or for tampering with utility facilities; and b. the Company can verify prior utility service either by contact with the former utility or through an authorized letter provided by the former utility on the utility letterhead that states the dates service was provided to Applicant and that the Applicant voluntarily terminated service and timely paid for all services rendered; and c. Applicant does not owe an account balance to the Company or another Oregon energy utility that was not paid in full when service was terminated. 2. Applicant provides proof of ability to pay by providing one of the following: a. Proof of employment during the 12 consecutive months prior to the date of application with not more than two different employers, along with a telephone number(s) to verify employment; or b.

16 Original Sheet RR-2.3 Rule 2. Establishment and Re-establishment of Credit. NON-RESIDENTIAL SERVICE: I. General The Company will not approve a Non-Residential application for service until the Applicant(s) has established satisfactory credit or otherwise provided sufficient security, as set forth in this General Rule 2. The establishment or re-establishment of credit or the Company s acceptance of other security under this General Rule shall not relieve a Non-Residential Applicant or Customer from complying with the Rules and Regulations established by the Commission, including but not limited to, the prompt payment of bills and the Disconnection of Service for nonpayment. If the principals of a corporation, partnership or other Non-Residential enterprise are substantially the same as those of another corporation, partnership or Non-Residential enterprise that either is or has at one time received Natural Gas service from the Company, then they will be deemed to be the same corporation, partnership or Non-Residential enterprise for the purposes of establishing or re-establishing credit standing under this General Rule 2. In order to be considered substantially the same as those of another corporation, partnership or Non-Residential enterprise, seventy-five percent (75%) of the business ownership must be the same. Where there are only two principals, both principals must be the same in order to be considered substantially the same corporation, partnership, or Non-Residential enterprise. For purposes of establishing or re-establishing credit, a builder, contractor, property developer, or property manager shall be considered a Non-Residential Applicant on any application made for gas service to real property for which they are responsible through their business activities, whether the property is classified as Residential or Non-Residential. A Non-Residential Applicant or Customer that is required to pay a deposit will be deemed to have established or re-established credit when they have maintained an active account with the Company for one Year and during such Year: (a) Customer did not receive more than two final notices of disconnection (also known as a 5-day notice), and (b) Customer was not disconnected for nonpayment, theft, diversion of service, or for tampering with utility facilities. If there are multiple active accounts for the same Customer, all such accounts must meet the above requirements.

17 Original Sheet RR-2.4 Rule 2. Establishment and Re-establishment of Credit. NON-RESIDENTIAL SERVICE: II. Establishment of Credit. This section applies to all Non-Residential Applicants, and to any Non-Residential Customer that is required to re-establish credit as set forth in Section III of this General Rule 2. If any Non-Residential Applicant or Customer has multiple active or inactive gas service accounts with the Company for the same class of service, then the account history of all such accounts may be considered in the establishment or re-establishment of credit. If the estimated monthly bill for service under any new application is higher by 50% or more than the average monthly bill of the Applicant s other accounts for the same class of service, then a deposit may be required, irrespective of the credit standing on such Applicant s other gas service accounts. An Applicant with multiple active accounts where no single account has been active for a consecutive 12-month period, may meet the requirement for 12-months of continuous service by combining the nonduplicative active months across all accounts (i.e. account #1 was active January-May; Account #2 was active April through December). If the consecutive 12-month period cannot be met (i.e. the accounts were all activated less than 12 months and for the same calendar months), then a deposit as set forth in General Rule 6B may be required. A Non-Residential Applicant or Customer must meet all of the following conditions to establish or reestablish credit: a. Is licensed to do business in the state of Oregon and has kept current over the past twelve (12) consecutive months on all real estate mortgages or lease agreements, commercial loans, utility bills and trade accounts; and b. Has not been involved in a solvency proceeding, including but not limited to bankruptcy, receivership, liquidation, bulk sale, or financial reorganization, naming the Applicant or any principals of the corporation, partnership, or Non- Residential entity as a debtor party to the filing at any time during the prior thirtysix (36) consecutive months; c. Immediately prior to the date of application, Applicant received twelve (12) consecutive months of service with the Company or another energy utility; and i. Received no more than two final disconnection notices during such 12- month period; and ii. Did not have service disconnected for non-payment, theft, diversion of service, or for tampering with utility facilities during such 12-month period; and iii. Does not owe a past due amount.

18 Original Sheet RR-2.5 Rule 2. Establishment and Re-establishment of Credit. NON-RESIDENTIAL SERVICE: If any one of the above conditions cannot be met, the Non-Residential Applicant or Customer must pay a deposit, and the Company may require the Applicant to provide other security, as set forth in General Rule 6B. The Company may also require additional credit or financial information deemed necessary in its judgment to determine credit worthiness. Customer will have five (5) Business Days from the date of the Company s request to provide the Company with such information. III. Re-establishment of Credit. Any Non-Residential Customer may be required to re-establish credit under this General Rule 2 when the conditions of service or the basis upon which credit was originally established has changed, including: (a) (b) (c) (d) (e) (f) (g) (h) A change in the type of business in use at the service address; A business name change; A change in responsible party(ies); A change in ownership; The expiration or termination of Customer s Oregon business license; Customer was found to have established credit standing based on false or incomplete information; Customer has been approved by the Company to select a different Service Type that results in an expected change to the average monthly bill for such Customer of 50% or more; or Other circumstances which the Company can be reasonably certain may result in Customer s inability to regularly and timely pay for services rendered by the Company or that otherwise may have the potential to adversely affect rates for other ratepayers of the Company. When a Non-Residential Customer is required to re-establish credit, the Customer must then meet all of the conditions set forth in Section II of this General Rule 2 based on the most recent 12 months of service with the Company. If any one of these conditions cannot be met, Customer may be required to pay a deposit, pay an additional deposit, and/or provide other security as set forth in General Rule 6B. The Company may also require additional credit or financial information deemed necessary by the Company to determine credit worthiness. Customer will have five (5) Business Days from the date of the Company s request to provide the Company with such information.

19 Original Sheet RR-3 Rule 3. Written Service Agreements. The Company reserves the right to require any Customer to enter into a written Service Agreement as a condition of service. In all cases, a written Service Agreement will be required as a condition precedent to service when any Rate Schedule or Rule contained in this Tariff specifies that a written Service Agreement is required. All Service Agreements will incorporate the General Rules and Regulations of this Tariff, other applicable Schedules, and the terms and conditions of Customer s Rate Schedule. In the event of a conflict, the terms and conditions of the Rate Schedule shall prevail. The term of a written Service Agreement shall be no less than the term stated in the applicable Rate Schedule or Rule, or a minimum of one Year, if not stated. Termination of a written Service Agreement by a Customer must comply with the provisions of RULE 16, or otherwise comply with the notice provisions stated in the Service Agreement. The interpretation and performance of any Service Agreement shall be in accordance with the laws of the state of Oregon, excluding principles of conflict of law, and the valid laws, orders, rules, and regulations of the authorities having jurisdiction (or the successors of those authorities). Except as required by law, order, rule or regulation, a written Service Agreement may only be amended or modified in writing. Any amendment or modification must be signed by Customer and by the Company. No Service Agreement, or any related rights or obligations, may be assigned by Customer without the prior written consent of the Company, which shall not be unreasonably withheld. If during the term of a written Service Agreement, the Rate Schedule or Rule to which the written Service Agreement applies is cancelled or replaced by order of the Commission, the written Service Agreement shall (a) automatically terminate or (b) if specified in the Commission s order, transfer to successor Rate Schedule or Rule and continue in effect. If the Company waives any one or more defaults by a Customer in the performance of a Service Agreement, the waiver(s) shall not operate or be construed as a waiver of any other future default(s).
