If gross production tax is paid to the commissioner and the reports accompanying such tax are insufficient to enable the commissioner to determine the source, by county, from which it is produced, the state treasurer shall allocate those revenues under this section. In the first distribution to counties under section 57-51-15 which occurs after June gross production tax revenues are received by the state treasurer for allocation, the revenue under this section must be allocated among counties in the same proportions that revenue was allocated among counties that received distributions under section 57-51-15 during the year ended June thirtieth. Revenue received by the county under this section must be allocated within the county as provided in section 57-51-15.
