An amount of $7,389 has bccn �vithheld since Ma,y, 1999. The proposed contract changes and prices wil[ be effec#ive 511/02, applied retroactively, and are contu�gent upou renewal and extension of the axisting r.�ntract. I�vould like to suggest some tatidfill priciiag clianges I believe will benefrt the Coiant,y. • Iucrease t�ie sales price of fopsoil frotn $ I�.50 to $19.�a.
