The comptroller of the treasury or the comptroller's designee shall require such periodic information from a unit operating under this chapter and make such audits as the comptroller of the treasury or the comptroller's designee deems necessary, to the end that it may be ascertained that the budget of the unit is kept balanced during the life of bonds issued under this chapter. The annual budget of each unit operating under this chapter shall be submitted to the comptroller of the treasury or the comptroller's designee at least three (3) weeks prior to its adoption. The comptroller of the treasury or the comptroller's designee must thereupon determine whether or not the budget will be in balance in accordance with this chapter. If the budget does not comply with this chapter, the comptroller of the treasury or the comptroller's designee shall have the power and authority to direct the governing body of the unit to adjust its estimates or to make additional tax levies sufficient to comply with this chapter. No budget shall be adopted by the governing body of a unit which shall have issued bonds under this chapter until it shall have been approved by the comptroller of the treasury or the comptroller's designee. The comptroller of the treasury or the comptroller's designee shall approve the budget only when the comptroller of the treasury or the comptroller's designee is satisfied that it complies with this chapter.
