Issues related to a diesel fuel release that occurred on the mine property in 2001 were addressed in TR-003. That revision contained statements prepared by Scott Rutherford, Paragon Consulting Group, that soil abatement activity beyond that which had already been completed was not warranted, however the parameters of TR-003 anticipated additional extraction activity adjacent to the abatement area which would provide for excavation of any remaining contaminated soil. Extraction activity at the 83'~ Joint Venture site was recently completed without additional mining adjacent to the abatement area because it was determined that aggregate reserves in that area are not economically recoverable. As Paragon's original assessment and further evaluation indicate that the Division's groundwater quality goals have been achieved for this site without the necessity of additional extraction adjacent to the abatement area, Aggregate Industries requests release from any requirement to excavate in accordance with TR-003 and that the site be released from further assessment or abatement activity related to the matter of the 2001 fuel release. Paragon's additional evaluation of the potential effect of the remaining soil contamination on goundwater quality, originally submitted to the Division on March 11, 2003, is resubmitted herewith in support of this request. We appreciate your consideration of this technical revision request. Enclosed is an additional copy of this letter request together with a check for the technical revision processing fee. Please contact me at (970) 336-6526 if you have any questions or need additional information. The Division's response should be addressed to my attention as follows: Connie N.
