STEP 2: SIGNIFICANCE OF THE RESOURCE 660-023-0180 (2) (b) Local Governments shall apply the criteria in section (3) or (4) of this rule, whichever is applicable, rather than OAR 660-023-0030(4), in determining whether an aggregate resource site is significant. The criteria in section (3) of this OAR is applicable to this PAPA application. OAR 660-023-180 (3): An aggregate resource site shall be considered significant if adequate information regarding the quantity, quality, and location of the resource demonstrates that the site meets any one of the criteria in subsections (a) through (c) of this section, except as provided in subsection (d) of this section: (a) A representative set of samples of aggregate material in the deposit on the site meets the applicable Oregon Department of Transportation (ODOT) specifications for base rock for air degradation, abrasion, and soundness, and the estimated amount of material is more than 2,000,000 tons in the Willamette Valley, or more than 500,000 tons outside the Willamette Valley; This criterion requires review of two characteristics of the resource: quantity and quality. The estimated quantity of the resource must exceed 2 million tons. The applicant’s report concludes that there is over 8 million cubic tons of material present beneath the site, an amount well in excess of the 2 million cubic ton requirement. The quality of the resource must meet ODOT standard specifications for highway construction. The original sampling methodology is described in Exhibit 1, Evaluation of Aggregate Resources: Delta Sand and Gravel Expansion Area, by EGR & Associates. Issues raised under the quality criterion include: adequacy of methodology used to test the material ? adequacy of bore hole coverage ? adequacy of the data recorded from the samples taken ? Elaboration of the issues are found in the following submittals: Exhibit 1 -- Evaluation of Aggregate Resources: Delta Sand and Gravel Expansion Area, by EGR & Associates, Inc. in the original application. File Record No. 18 – Memo from Shane Hughes, PE, EGR & Associates, Inc. Exhibit 19 – Letter from Mark H. Reed, Mineral Resource Geologist. Exhibit 33a -- Testimony of Concerned Santa Clara Residents Organization (SCRO) on Delta Mining Expansion Proposal – Mark H. Reed testimony in response to EGR analysis (ASTM Standard Practice for Sampling Aggregates) Exhibit 46 – Letter from Karen Reed Exhibit 47 – Letter from Ralph Christensen, Senior Geologist, EGR & Associates, Inc. (ASTM Standard Practice for Sampling Aggregates) Exhibit 50 – letter from Steve Cornacchia Exhibit 62 – Letter from Mark Reed The record contains expert geologic testimony on both sides of this issue. The applicant’s analysis by EGR and Associates was reviewed by another certified geologist, and the SCRO resource geologist also reviewed the data and submitted comments. The AASHTO ASTM Standard Practice for Sampling Aggregates language describes the sampling protocol for roadside or bank run sand and gravel deposits under Appendix D75, section X2.3.2. (b) The material meets local government standards establishing a lower threshold for significance than subsection (a) of this section; or Board/Council Hearing – Ordinance No. PA 1238 Delta Sand & Gravel Expansion Agenda Cover Memo Page 7 of 23
