Population shall be based on the most recent census. 2. (a) (1) Notwithstanding any other provisions of law to the contrary, any school district of this state, acting through its local legislative body, is hereby authorized and empowered to adopt a resolution imposing in any such school district an annual assessment of not more than two per centum of the gross receipts of any commercial hazardous waste facility which is located in such school district and may make provisions for the collection thereof.

The distribution of annual assessment revenues among the school districts located in the town or city where the facility is located shall be done on a proportionate basis, based upon the number of students of each school district residing in the town or city where the facility is located.
(4) The distribution from the school district collecting the annual assessment revenue to any other district entitled to a proportionate basis shall be made within sixty days of receipt of the annual assessment revenues.
