A written response to a unit clarification petition must be filed with the Board within 15 calendar days of the date the Board provided the respondent with a copy of the petition. The respondent shall file with the Board a written response indicating whether it agrees with the modification proposed in the petition and the basis of any objection. A copy of the response must be simultaneously served on the petitioner. If no response is filed by a respondent within the 15-day response period, or within an extension of time allowed by the executive director, the respondent will be deemed to have agreed to the modification.
