      "title": "Air Pollution: Legal Perspectives on the \u201cRoutine Maintenance\u201d Exception to New Source Review",
      "summary": "A major Clean Air Act issue is the extent to which an existing power plant or factory may be altered without effecting a \u201cmodification.\u201d A \u201cmodification\u201d of an existing air pollution source is subject to the act\u2019s stringent air pollution control requirements for new sources. The topic of this report is a widely used exemption to \u201cmodification\u201d allowing changes that constitute \u201croutine maintenance, repair, and replacement\u201d without triggering such stringent requirements. The report surveys the original legal landscape surrounding this exemption\u2014in the contexts of determining applicability of New Source Performance Standards, and New Source Review in Prevention of Significant Deterioration and nonattainment areas. It then summarizes the many significant developments during the current Bush Administration, both in the Federal Register and in the courts. This report will be updated as events warrant.",
