The state risk manager may extend such period if the risk manager finds that such local government entity or entities are making a good faith effort and taking all necessary steps to comply with this chapter; however, in no event may the risk manager extend the period required for compliance more than ninety days after the expiration of the initial one hundred eighty-day period.
