LONGVIEW — Eight Southwest Washington lawmakers are urging U.S. Rep. Jaime Herrera Beutler, R-Battle Ground, to represent Norpac at a trade hearing next month on controversial tariffs levied against Canadian papermakers. The hearing is related to a trade petition filed by Norpac with the U.S. Department of Commerce last August, which has roiled the market for uncoated groundwood paper — the same product used to produce newspapers, books and printed mailers. A sudden spike in the cost of newsprint has thrust the Longview paper mill into the national spotlight and into a conflict with the newspaper industry, which consumes millions of tons of newsprint, its second-biggest cost after payroll. Local state lawmakers sent a letter to Herrera Beutler on Monday asking her to advocate for Norpac in a July 17 trade hearing, noting that Norpac has hired 50 new employees and restarted a paper machine that was idled last fall.
