For having unity between the charge manager and the person charged to submit:

- There should be clear and specific regulations on the conversion ratio between units of measurement of minerals to be charged for each type of mineral.

- There should be agreement on the collection rates of all localities in the whole country: For the same types of mines, minerals, mining process and technological chain, the level of pollution the same environment. Therefore, it is not possible for two mines to be located in the same geographic location but because in different locations the different charge rates are unreasonable.

If the charge rates are considered "unloading", then at each specific time, it is necessary to stipulate that a fee for each mineral ore at that time shall be fixed for the whole country.
