Transportation (ODOT) specifications for base rock for air <br />degradation, abrasion, and sodium sulfate soundness, and the <br />estimated amount of material is more than 2,000,000 tons in the <br />Willamette Valley <br /> <br />EGR has been retained by the applicant to evaluate the aggregate material reserves in the <br />proposed expansion area. EGR is a long-standing engineering firm in Eugene, Oregon, with <br />licensed and experienced engineers. EGR is a legitimate technical resource that has the expertise <br />and experience to conduct evaluations of aggregate material deposits in Lane County, Oregon. <br /> <br />EGR published the results of its evaluation in the document titled “Evaluation of <br />Aggregate Resources: Delta Sand and Gravel Expansion Area, dated June 2005, and a copy of <br />the EGR report is attached as an exhibit to the application. In that report, EGR determined that <br />coarse aggregate samples obtained during its field exploration of the expansion area met ODOT <br />base rock specifications. The report contains laboratory data demonstrating that the coarse <br />aggregate (gravel) fraction present at the expansion site meets the base rock specifications <br />required by ODOT and Goal 5. Similarly, the report demonstrates that all of the coarse <br />aggregate samples meet the ODOT soundness requirements for Portland Cement Concrete. <br />Furthermore, EGR concluded that the estimated volume of aggregate available within the <br />proposed expansion area is 9,082,260 tons (more than four times the volume required by rule). <br />That information demonstrates that the expansion area meets the criteria of OAR 660-023- <br />0180(3)(a). <br /> <br />Opponents of the application testified that they believed that EGR’s methodology for <br />sampling should be challenged and that EGR’s sampling and conclusions regarding the quantity, <br />quality and location of the aggregate resource existing within the expansion area should be <br />independently verified. In testimony following the joint planning commission public hearing, <br />EGR effectively rebutted the arguments of opponents regarding the quantity, quality and location <br />of the aggregate resource. Furthermore, in testimony during the joint elected officials’ public <br />hearing, the applicant provided evidence to support its methodology and conclusions in the form <br />of correspondence from ODOT and DOGAMI. ODOT’s correspondence confirmed EGR’s <br />conclusion that material sampled from the aggregate deposit on the subject property met ODOT <br />specifications for base rock (ODOT tested representative samples from the EGR borings to reach <br />its conclusion). DOGAMI’s correspondence confirmed that the sampling and conclusions by <br />EGR and ODOT were correct and result in a finding that the subject expansion area contains a <br />significant deposit of aggregate material and that the site is a significant aggregate site that meets <br />the criteria of OAR 660-023-0180(3)(a). <br /> <br />We also note, for purposes of providing supporting reasoning for these findings, that the <br />expansion area is proposed as an extension of an existing significant resource site that has been <br />mined by the applicant for more than 80 years. We find it reasonable to expect that land <br />immediately adjacent to an existing significant resource site will also contain a significant <br />deposit of aggregate material similar to that of the existing site. <br /> <br />Based upon the applicant’s testimony, ODOT and DOGAMI confirmation of the <br />conclusions contained in that testimony and the fact that the applicant is proposing to expand an <br />existing aggregate site containing a significant deposit of aggregate material, we find that the <br />subject property is a significant aggregate site as defined by the Goal 5 administrative rule. <br /> <br /> (d)Notwithstanding subsections (a) through (c) of this <br />section, except for an expansion area of an existing site if the <br />operator of the existing site on March 1, 1996 had an <br />enforceable property interest in the expansion area on that date, <br />Page 9 – FINDINGS OF FACT <br /> <br />
