Over the last decade, phase one of the Clean Air Act’s regional haze program cost companies (primarily electric generating companies) hundreds of millions of dollars in compliance costs and caused the early closure of a number of facilities. The program is just now entering the initial stages of its second planning period, with major implementation activities expected over the next few years. Unsuspecting companies are finding themselves the targets of the program’s requirements for the first time. In states that have taken early action—Arizona, New Mexico, North Dakota, Oregon and Washington—there has been a shift in attention from older power plants to oil and gas operations and manufacturing facilities in the pulp and paper, cement, and minerals sectors, among others. Even companies that have been through this regulatory process before are facing difficult new questions due to major rule changes enacted in 2017, changes to guidance and key technical documents, and a new focus on statutory provisions addressing “reasonable progress” that were not often used in the past. Hunton Andrews Kurth LLP partner Aaron Flynn has assisted numerous clients in dealing with regional haze issues. In this video, partner Allison Wood interviews Aaron regarding the recent developments in the regional haze program and regarding how companies can best position themselves as states and EPA decide on the next round of emission control requirements.
