Our discussion of alternatives and mitigation are reflected in the subject diary note. The proposed rock drilling should take place using only ethyl alcohol as the antifreeze agent. I do not sanction use of any other antifreeze agent, at this time. In addition, there must be no rock drilling or use of antifreeze agents at Linneaus Terrace, Wright Valley (Site of Special Scientific Interest No. 19). Entry to this site requires a permit. No such permit has been approved for this award. The Program Manager should attach a copy of this memorandum to the grant jacket for future reference. Please advise the Principal Investigator about these decisions as soon as possible. Sidney Draggan
