California Code, Public Resources Code - PRC § 42773

If a consumer of newsprint is unable to obtain sufficient amounts of recycled-content newsprint within any reporting period because recycled-content newsprint was not available at a comparable price to that for virgin material, failed to meet the quality standards established pursuant to Section 42775, or was not available within a reasonable period of time, the consumer of newsprint shall so certify to the board and shall provide the board with the specific reason for failing to use recycled-content newsprint.  In order to make that certification in good faith, the newsprint consumer shall have contacted, for the purpose of obtaining recycled-content newsprint, every producer of recycled-content newsprint that offered to sell recycled-content newsprint to the consumer of newsprint within the last 12 months.  The name of each person contacted, the corporate name, if any, and address and telephone number shall accompany each filing with the board.
