If a district is required to collect an impact fee for another political subdivision which has complied with the procedures set out in the Local Government Code, Chapter 395, then the district is not required to seek further approval from the commission of the same fee. A test for applying this section shall be that the district does not retain any portion of said impact fee for its own use, but that it passes all such fees through to the political subdivision which has adopted said impact fee.
