(1) Time periods for acts required by these rules will exclude the first day and include the last day, unless the last day falls on a Saturday, Sunday, or legal holiday. In that event, the period runs until the end of the next regular workday, which is not a Saturday, Sunday, or legal holiday. 

(2) All claims, complaints, requests, responses, and documents required or allowed to be submitted to the department: 

(a) may be submitted in person, by regular mail, electronically (e-mail), by facsimile (fax), or via online portal when available; and

(b) are considered filed with the department on the date the department receives them.

(3) Submissions received after 11:59 p.m. mountain time will have a filing date of the next regular workday.

(4) Parties must ensure that submissions are timely received by the department. Failure, malfunction, or unavailability of electronic equipment does not excuse a party from the requirements of timely filing.

(5) Only one copy of an e-mail or fax submission must be filed even if multiple copies otherwise would be required.
