Prior to the issuance of any bonds to finance the cost of an economic development project that will be repaid in whole or part from apportionments under this chapter, the municipality or industrial development corporation issuing such bonds shall submit a proposed debt amortization schedule for such bonds to the commissioner for approval. Such schedule shall show the anticipated contribution to be made to the annual debt service for such bonds from the apportionment of sales and use taxes pursuant to this chapter and all other sources. After the date of issuance of such bonds, the municipality shall continue to contribute each year thereafter until such bonds are retired or a sufficient sinking fund has been established for their retirement.
