The governing body of any municipal corporation establishing an environmental advisory council may appropriate funds for the expenses incurred by the council. Appropriations may be expended for those administrative, clerical, printing and legal services as may be required and as shall be within the limit of funds appropriated to the council. The whole or any part of any funds so appropriated in any year may be placed in a conservation fund and allowed to accumulate from year to year or may be expended in any year.
