(Appendix K). The report consisted of an updated inspection of parcel 37 and the <br />primary and secondary access roads to supplement the previous archaeological inventory <br />survey of parcel 36 completed in 1992. The report also updated the previous cultural <br />impact assessment of parcel 36 completed in 1992 with the addition of parcel 37 and the <br />access roads. Four quarry sites consisting of seven component features, all pahoehoe <br />excavations, were identified but no subsurface test excavations were conducted since <br />there were no cultural deposits of any kind within the identified features. DLNR-SHPD <br />determined that no further work or preservation was recommended for any of the sites. <br />The study confirmed that the project site has been extensively modified and developed for <br />the operation of the applicant's Keahole Generating Station and Airport Substation. The <br />study also concluded that the proposed action will not significantly affect or adversely <br />impact any historic properties or archaeological resources, and no mitigation measures are <br />necessary. <br />26. Cultural Resources: No evidence of any potentially significant traditional native <br />Hawaiian cultural properties, natural resources, practices, or beliefs were identified <br />during either the 1992 inventory survey or the updated assessment conducted in 2003. <br />The Archaeological and Cultural Impact Assessment Study by Paul H. Rosendahl, Ph.D., <br />Inc., conducted in February 2004 (Appendix K) concluded that "based on the absence of <br />any evidence that the project site is currently being used for any legitimate traditional <br />cultural purposes by either native Hawaiian cultural practitioners or individuals of any <br />other cultural affiliation, it can be concluded that the HELCO KeahoIe Generating Station <br />Project should have no significant effects - much less any adverse impacts - upon any <br />cultural resources, and that no mitigation measures of any kind are needed." <br />27. Noise Impacts: As noise may affect surrounding properties, mitigation measures such as <br />constructed barriers and landscaping are proposed to ameliorate potential adverse <br />impacts. HFP Acoustical Consultants Inc. prepared a study titled, Noise Study for DEIS <br />in October 13, 2004 (Appendix H). Noise sources in the vicinity of the Keahale <br />Generating Station include various diesel generators and combustion turbines, vehicular <br />traffic on Queen Kaahumanu Highway, and aircraft at the Kona International Airport at <br />10 <br />
