After July 1, 1980, a state agency which sponsors, in whole or in part, a meeting or conference for the public or for state employees shall ensure that a physically disabled participant who gives reasonable advance notice to the agency will receive the auxiliary aids necessary for effective participation. Auxiliary aids may include taped or Brailled materials, interpreters or other effective means of making orally delivered material available to participants who are deaf, deafblind, and hard-of-hearing, and equipment adaptable for use by participants with manual impairments and other similar services and action; however, nothing in this section shall (1) require a state agency to provide attendants, individually prescribed devices, or other devices or services of a personal nature or (2) apply to the Minnesota State Colleges and Universities or the University of Minnesota with respect to classes, seminars or training programs which are offered by them. When sign language interpreters are provided, they shall be provided in a manner so that participants who are deaf, deafblind, and hard-of-hearing will be able to see their signing clearly. For the purposes of this section, "physically disabled" has the meaning given in section 326B.103, subdivision 10. For the purposes of this section, "agency" means any state officer, employee, board, commission, authority, department or other agency or the executive branch of state government.
