The parties to this Agreement agree to a new procedure for resolving jurisdictional disputes under Regional Instruction 399 (hereafter RI-399). The new procedures will be implemented sixty (60) calendar days after the effective date of this Agreement. Effective with the signing of this Agreement, no new disputes will be initiated at the local level by either union challenging jurisdictional work assignments in any operations as they currently exist. Except as otherwise specifically provided in the New or Consolidated Facilities, New Work, or Operational Change sections contained in this memorandum, all local craft jurisdictional assignments which are not already the subject of a pending locally initiated grievance will be deemed as a proper assignment for that facility.
