The commission may allow tariff filings to become effective with less notice than is shown in WAC 480-70-262 and 480-70-271 when there is an emergency or when merit is shown. This process is known as "less than statutory notice" (LSN) handling. A company filing for LSN handling may use an LSN form supplied by the commission, or a letter containing at least the following information:

(1) Company identification information:

(a) Name and registered trade name;

(b) Certificate number;

(c) Address;

(d) Telephone number, email address, and telefacsimile number; and

(e) Name and telephone number of a person to contact regarding the filing;

(2) Tariff identification information:

(a) Number of the tariff being amended;

(b) Identifying number and title of the tariff item(s) being amended; and

(c) Number of the tariff page being amended;

(3) Concise description of the provisions being proposed;

(4) Reason(s) for requesting LSN handling; and

(5) Effective date requested.
