469.1. The parties to an agreement contemplated in this subsection and in subparagraph b of paragraph 10 of section 413 may provide therein that any other municipality may join the agreement.
An agreement which provides that it may be joined must determine, or provide a mechanism for determining, all or part of the conditions of joining. Such conditions are effective notwithstanding any inconsistent provision of any general or special Act.
A municipality, by resolution of its council, may join an agreement which provides therefor, on the conditions determined by or pursuant to the agreement.
A municipality which joins an agreement must transmit, for approval, a copy of the resolution and, where such is the case, a statement of the conditions not determined in the agreement, to the Minister of Municipal Affairs and to any other minister or any body that must approve the agreement.
Not less than thirty days before sending the documents provided for in the fourth paragraph, the municipality must send the same documents to each party to the agreement.
The municipality becomes a party to the agreement once the resolution and, where such is the case, the conditions of joining not determined in the agreement have received every required approval. The agreement is then deemed amended accordingly and the Minister of Municipal Affairs may, if necessary, amend the order establishing the management board which he issued in accordance with section 468.11.
