(1) Where to file communications with the board. Except as provided elsewhere in this section all written communications shall be filed with the board at its headquarters in Olympia, Washington. With written permission of the industrial appeals judge assigned to an appeal, depositions, witness confirmations, motions (other than motions for stay filed pursuant to RCW 51.52.050), briefs, stipulations, agreements, and general correspondence may be filed in the appropriate regional board facilities located in Tacoma, Spokane, or Seattle.

(2) Methods of filing. Unless otherwise provided by statute or these rules any written communication may be filed with the board by using one of four methods: Personally, by mail, by telephone facsimile, or by electronic filing. Failure of a party to comply with the filing methods selected by the party for use under this section, or as otherwise set forth in these rules or statute for filing written communications may prevent consideration of a document.

(a) Filing personally. The filing of a written communication with the board personally is accomplished by delivering the written communication to an employee of the board at the board's headquarters in Olympia during customary office hours.

(b) Filing by mail. The filing of a written communication with the board is accomplished by mail when the written communication is deposited in the United States mail, properly addressed to the board's headquarters in Olympia and with postage prepaid. Where a statute or rule imposes a time limitation for filing the written communication, the party filing the same should include a certification demonstrating the date filing was perfected as provided under this subsection. Unless evidence is presented to the contrary, the date of the United States postal service postmark shall be presumed to be the date the written communication was mailed to the board.

(c) Filing by telephone facsimile.

(i) The filing of a written communication with the board by telephone facsimile is accomplished when a legible copy of the written communication is reproduced on the board's telephone facsimile equipment during the board's customary office hours. All facsimile communications must be filed with the board via fax numbers listed on the board's website.

(ii) The hours of staffing of the board's telephone facsimile equipment are the board's customary office hours. Documents sent by facsimile communication comments outside of the board's customary office hours will be deemed filed on the board's next business day.

A separate transmission must be used for each appeal. Transmissions containing more than one docket number will be rejected and filing will not be accomplished, unless the multiple docket numbers have been previously consolidated by the board.

(iv) The party attempting to file a written communication by telephone facsimile bears the risk that the written communication will not be received or legibly printed on the board's telephone facsimile equipment due to error in the operation or failure of the equipment being utilized by either the party or the board.

(v) The board may require a party to file an original of any document previously filed by telephone facsimile.

(d) Electronic filing. Electronic filing is accomplished by using the electronic filing link on the board's website. Communication sent by email will not constitute or accomplish filing. Communication filed using the board's website outside of the board's customary office hours will be deemed filed on the board's next business day. A separate transmission must be used for each appeal. Transmissions containing more than one docket number will be rejected and filing will not be accomplished, unless the multiple docket numbers have been previously consolidated by the board.

(3) Electronic filing of a notice of appeal. A notice of appeal may be filed electronically when using the appropriate form for electronic filing of appeals as provided on the board's website. An electronic notice of appeal is filed when it is received by the board's designated computer during the board's customary office hours pursuant to WAC 263-12-015. Appeals received via the board's website outside of the board's customary office hours will be deemed filed on the board's next business day. The board will issue confirmation to the filing party that an electronic notice of appeal has been received. The board may reject a notice of appeal that fails to comply with the board's filing requirements. The board will notify the filing party of the rejection.

(4) Electronic filing of application for approval of claim resolution settlement agreement. An application for approval of claim resolution settlement agreement must be filed electronically using the form for electronic filing of applications for approval of claim resolution settlement agreement as provided on the board's website.

The board will reject an application for approval of claim resolution settlement agreement that fails to comply with the board's filing requirements. The board will notify the filing party of the rejection.

(5) Sending written communication. All correspondence or written communication filed with the board pertaining to a particular case, before the entry of a proposed decision and order, should be sent to the attention of the industrial appeals judge assigned to the case. Interlocutory appeals should be sent to the attention of the chief industrial appeals judge. In all other instances, written communications shall be directed to the chief legal officer of the board.
