Industry Rule 3. Serving Advice Letters (see General Rules 4.3, 7.2)

On or before the date an advice letter is submitted for filing, in addition to serving the advice letter as required by General Rule 7.2, the Utility shall serve the advice letter as follows:

(1) If the advice letter requests approval of a Contract or other deviation, serve all parties to the Contract or other deviation.

(2) If the advice letter requests approval of rates for an oil pipeline not previously in Utility service, serve all current or potential customers of the oil pipeline.

(3) If the advice letter requests approval of a rate change for an oil pipeline already in Utility service, serve all shippers and submit to the Energy Division Filings Room at least 30 days before the requested effective date.

(4) Except for an advice letter described in (3) of this Industry Rule, if the advice letter requests a change that would cause an increase in a rate or charge, reduction in service, discontinuance of a program, closing a rate schedule to new customers, canceling a rate schedule, or abandoning service to an area, serve all affected customers.

(5) If the advice letter proposes a new product or service, serve all Utilities and other providers that may compete within the area to be served.
