Title 42 › Chapter CHAPTER 85— - AIR POLLUTION PREVENTION AND CONTROL › Subchapter SUBCHAPTER I— - PROGRAMS AND ACTIVITIES › Part Part A— - Air Quality and Emission Limitations › § 7419
Lets owners or operators of certain primary nonferrous smelters ask for a special EPA order that can delay a sulfur‑oxide emission limit when three things are true: the smelter existed on August 7, 1977; the rule being delayed is a sulfur‑oxide limit meant to meet national air quality standards; and the smelter cannot meet the rule by the deadline because no control method has been shown to be reasonably available (the EPA decides this after looking at cost, health and environmental effects not related to air, and energy issues). The EPA Administrator or the state where the smelter is located can issue the order, but a state order won’t take effect until the EPA finds it was issued properly. A smelter cannot have both this special order and an enforcement order under section 7413(d). If someone applies for a second order, they must give the EPA or state a written statement with supporting documents, make that public for 30 days before any hearing, and the decision must include a short statement of the findings. No smelter may get more than two of these orders. The first order cannot delay the requirement past January 1, 1983, and the second cannot delay it past January 1, 1988. A second order must include a schedule of steps and deadlines to reach compliance as quickly as possible and to buy, install, and run needed controls once EPA finds they are reasonably available. While an order is in effect, the smelter must use interim measures to protect air quality. Those interim rules must include monitoring and reporting, steps to prevent an imminent danger to health, and usually continuous emission‑reduction technology unless the state or EPA grants a waiver after a public hearing showing the cost would force prolonged or permanent shutdown (the EPA must be notified and hold a hearing within 90 days). If the EPA finds the conditions for the order no longer exist, it can end the order after a public hearing, with limited delay if ending it would cause undue hardship but not beyond the dates above. If a smelter breaks the order’s requirements, the EPA may enforce the rules, revoke the order and force compliance, start noncompliance actions under section 7420, or use a mix of these options.
