ORDER

Respondents-Intervenors Aaska Railroad Corporation and Matanuska-Susitna Borough’s motion to lift this court s October 1, 2012, order granting a stay of the Surface Transportation Board’s (STB’s) November 21, 2011, order is GRANTED. Leiva-Perez v. Holder, 640 F.3d 962, 964, 966 (9th Cir.2011) (stating the relevant standard); Alliance for the Wild Rockies v. Cottrell, 632 F.3d 1127, 1131-32, 1135 (9th Cir.2011) (same). Additionally, the petition for review of the STB’s order is DENIED. An opinion on the merits of denial of the petition for review will follow in due course. However, we think it appropriate to comment briefly now on our reasoning for lifting the stay.

Based on the merits briefing and the oral argument held before us, we conclude that Petitioners no longer satisfy the standard for issuance of a stay. See United States v. Houser, 804 F.2d 565, 568 (9th Cir.1986) (discussing a merits panel’s authority to reconsider a motions panel’s decision). This court initially determined that Petitioners raised a “serious question” regarding whether the STB complied with the National Environmental Policy Act (NEPA) in determining the “purpose and need” of the proposed rail line and that the balance of hardships tipped sharply in Petitioners’ favor. Order, Alaska Survival v. Surface Transp. Bd., No. 12-70218 (9th Cir. Oct. 1, 2012). After further review of the record, we have concluded that the STB’s “purpose and need” statement complied with NEPA and that Petitioners no longer raise “serious questions” on this point.

Moreover, the balance of hardships no longer tips sharply in the Petitioners’ favor. Further delay of this project will prevent the award of construction contracts, postpone the hiring of construction employees, and significantly increase costs. See Earth Island Inst. v. Carlton, 626 F.3d 462, 475 (9th Cir.2010) (noting that economic harm may be a factor in considering the balance of hardships). Because this project is funded largely with taxpayer dollars, these increased costs of construction, which the Respondents-Intervenors in moving to lift the stay estimated at $10-12 million, will burden the public upon continued delay. By contrast, the weight to be given Petitioners’ assertions of hardship because of environmental harm is weakened by this court’s decision to deny the petition for review, which will allow the project to move forward. Because we have concluded that the agency acted in accord with law and that its decision is not arbitrary and capricious, it is for the STB and not for our court to balance the justifications of planned economic progress in improved rail service against the possibilities of environmental harm from building and operating the rail line.

The time to file a petition for rehearing or a petition for rehearing en banc of this court’s denial of the petition for review will begin to run when the subsequent opinion is filed. The time to file a petition for rehearing or a petition for rehearing en banc of the court’s decision to grant the motion to lift the stay will run as of the date of this order.
