4 Pa. Code § 6.3
Until the interagency agreement is executed, existing law and memoranda of understanding shall serve as the basis for determining and effecting any responsibilities that the departments named in the memoranda of understanding may have for providing services to children with disabilities. If there is a disagreement regarding the responsibility for providing early intervention, special education, related services or transition services, or that the memoranda of understanding do not include an agency that may have responsibility for the services, it is the responsibility of the Interagency Committee to Coordinate Services Provided to Individuals with Disabilities (Committee) to arrange for the modification of the existing memoranda of understanding, or the development of a new memoranda of understanding to include other agencies, which shall be contingent upon review and approval by the Office of General Counsel. If disputes cannot be resolved by the Committee, the issue shall be submitted to the Office of General Counsel for final resolution. No moneys for services may be encumbered by another agency unless those services are authorized by the existing memoranda of understanding, an interim memoranda of understanding, a duly executed modification thereof or pursuant to direction by the Office of General Counsel.
