The Applicant has committed to sampling the mineralized Crusher Fines for Acid Base Accounting <br /> (ABA)and Synthetic Precipitation Leachate Procedure(SPLP). The Applicant has also committed <br /> to submitting the results to the Division through a revision to the permit to direct how the Fines <br /> will be handled and disposed. In addition to the proposed tests above, the Applicant will need to <br /> include sampling for TAL metals.
