Section 187-C. Biofuel production credit

A taxpayer shall be allowed a
  credit to be computed  as  provided  in  section  twenty-eight  of  this
  chapter,  against  the  tax  imposed by this article. Provided, however,
  that the amount of such  credit  allowed  against  the  tax  imposed  by
  section  one  hundred eighty-four of this article shall be the excess of
  the amount of such credit over the amount of any credit allowed by  this
  section  against  the tax imposed by section one hundred eighty-three of
  this article. In no event shall the credit under this section be allowed
  in an amount which  will  reduce  the  tax  payable  to  less  than  the
  applicable  minimum tax fixed by section one hundred eighty-three or one
  hundred eighty-five of this article. If,  however,  the  amount  of  the
  credit  allowed  under this section for any taxable year reduces the tax
  to such amount, the excess shall be treated as an overpayment of tax  to
  be credited or refunded in accordance with the provisions of section six
  hundred eighty-six of this chapter. Provided, however, the provisions of
  subsection  (c)  of  section  one  thousand eighty-eight of this chapter
  notwithstanding, no interest shall be paid thereon.
