<br />STEP 2: SIGNIFICANCE OF THE RESOURCE
<br />
<br />660-023-0180 (2) (6) local Governments shall apply the criteria in section (3) or (4) of this rule,
<br />. whichever is applicable, rather than OAR 660-023-0030(4), in determining whether an aggregate
<br />'. resource site ;s significan~~' ' , ".
<br />, The criteria in ,section (3) of -this OAR is applicable to this P~A application.
<br />
<br />OAR 660-023';'180 (3): An aggregate resource site shall be considered significant ifat/equate information .
<br />. regarding the. quantity, quality, and location of the resource demonstrates that the site meets anyone of
<br />. the criteria in subsections (a) through (c) of this section, except as provided in subsection. (d) of this
<br />secdon: ' ,
<br />
<br />. .
<br />
<br />(II) A representative set of samples of aggregate materia/in the deposit 0" the site meets the applicable
<br />Oregon Department of Transportation (ODOT) .specifications for base.' rock fo~ air degradation; . .
<br />abrasi~n, and soundness, ~nd the estimated amount' of material is more than 2,000, 00f) tons in th~ "
<br />:Willamette Valley, or more than 500,000 tons ouui~e the Wlllametle'Valley,.
<br />
<br />This criterion. requires review of two ch8racteristics of the resOuree: quantity. and quality. The
<br />. estimated quantity of the resource must exceed 2 million tons. The applicant's report concludes that
<br />there is over. 8 million cubic toDS of material present beneath the site, an amount well in excess of the 2
<br />, million cubic ton req~ent. . .
<br />
<br />The:quality of the reso~ must,meet OJ?<)T s~d specifi'?8tioDS for highway conStruction. .The.
