(a) The articles of an authority may at any time and from time to time be amended in the manner provided in this section. The board shall first adopt a resolution proposing an amendment to the articles, which amendment shall be set forth in full in the resolution and which may include any matters that might have been included in the original articles.
(b) After the adoption by the board of a resolution proposing an amendment to the articles, the chair and the secretary of the authority shall sign and file with the governing bodies of the county of incorporation, and each municipality whose corporate limits lie in whole or in part within the operational area of the authority, a written application in the name and on behalf of the authority, under its seal, requesting that such governing body or bodies adopt a resolution approving the proposed amendment, and accompanied by a copy of the resolution adopted by the board proposing the amendment to the articles. As promptly as may be practicable after the filing of the application, the governing body or bodies shall review the application and shall adopt a resolution either denying the application or approving and authorizing the proposed amendment. Such resolution need not be published or posted and need not be offered for more than one reading.
(c) Following the adoption of a resolution approving the proposed amendment by the governing body or bodies with which an application was filed pursuant to this section, the chair and the secretary of the authority shall sign and file for record in the office of the judge of probate of the county of incorporation a certificate in the name and on behalf of the authority, under its seal, reciting the adoption of resolutions by the board and by the governing body or bodies setting forth the proposed amendment. The judge of probate shall thereupon record the certificate in an appropriate book in his or her office. When the certificate has been so filed and recorded, the amendment shall become effective, and the articles shall thereupon be amended to the extent provided in the amendment.
(d) The failure of the governing body of the county of incorporation or any municipality whose corporate limits lie in whole or in part within the operational area of the authority receiving an application filed pursuant to this section to approve an application made pursuant to this section shall invalidate such application.
