With the initial “placed-in-service” requirements having been met during 2011 for 26 new RC facilities, ADA expects several of these to begin routine operations in 2012. Once the final utility site and tax equity partner have been determined, it takes an average of approximately six months to obtain permits for full-time operation, secure necessary approvals from Public Utility Commissions and negotiate and complete all necessary contracts. We currently have received $15 million from one financial institution as initial deposits on 15 million tons of RC, which reserves its right to negotiate for specific RC facilities. We are currently in discussions with other major financial institutions and corporate investors to reserve the right to negotiate on a number of the remaining facilities.
