(b) In calculating the three-day average price paid by recyclers within the specified distance of a recycler alleged to have engaged in predatory pricing, as required by subdivision (a), the department shall only survey those recyclers who did not receive handling fees in three or more of the 12 whole months immediately preceding the date of the allegation of predatory pricing.
(c) For purposes of this chapter, “rural region” means a nonurban area identified by the department on an annual basis using the loan eligibility criteria of the Rural Housing Service of the United States Department of Agriculture, Rural Development Administration, or its successor agency.
