On October 1, 2015, the United States Environmental Protection Agency (“EPA”) adopted stricter regulation on ozone emissions that will fall heavily on California, and most particularly on the transportation sector, including airlines. The new standard strengthens limits on ground level ozone to 70 parts per billion (“PPB”), down from 75 PPB adopted in 2008. The EPA’s action arises from the mandate of the Clean Air Act (“CAA”), from which the EPA derives its regulatory powers, 42 U.S.C. § 7409(a)(1), and which requires that pollution levels be set so as to protect public health with an “adequate margin of safety. 42 U.S.C. § 7409(b).
Two environmental organizations have again taken the United States Environmental Protection Agency (“EPA”) to task for failing in its mandatory duty to determine whether greenhouse gases from aircraft engines cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare (“Endangerment Finding”), and, if so, to propose and adopt standards to limit those emissions. See Clean Air Act (“CAA”), 42 U.S.C. § 7571(a)(2)(A) (also referred to as “Section 231”).
The Federal Aviation Administration (“FAA”) has added another arrow to its quiver in its ongoing campaign to limit residential and commercial development in even the remotest vicinity of airports. In late April, FAA originally published a “Proposal to Consider the Impact of One Engine Inoperative Procedures in Obstruction Evaluation Aeronautical Studies” (“Proposal”) which seeks to supplement existing procedures for analyzing the obstruction impact of new structures or modifications to existing structures on aircraft operations within certain distances around airports (see 14 C.F.R. Part 77), with consideration of the impact of structures on one engine inoperative (“OEI”) emergency procedures. OEI procedures are not currently included in FAA’s obstruction regulations which advise local land use jurisdictions on appropriate limits to building heights within specified geographic zones around airports to accommodate the takeoff and landing clearance needed by aircraft with their full complement of operating engines. From an aeronautical perspective, FAA’s initiative sounds desirable and long overdue, even though the occurrence of engine loss is rare. From the perspective of local jurisdictions, landowners and developers, however, the proposal is anathema, potentially leading to dramatically lower allowable building heights and concomitantly reduced property values, even far from the airport.
On June 18, 2012, the Environmental Protection Agency (“EPA”) posted in the Federal Register, Vol. 77, No. 117, 36342, its Final Rule adopting several new aircraft engine emission standards for oxides of nitrogen (“NOx”) for aircraft turbofan or turbojet engines with rated thrusts greater than 26.7 kilonewtons (kN), or in common parlance, commercial passenger and freighter aircraft normally used at airports across the United States. The rule applies only to the manufacture of new aircraft engines, not to retrofit of existing aircraft engines.
The EPA’s stated purpose in enacting the new rule is two-fold. First, NOx is strongly correlated with nitrogen dioxide (“NO2”) which is a “criteria pollutant” under the EPA’s National Ambient Air Quality Standards (“NAAQS”), and is an important precursor gas in the formation of ozone and secondary particulate matter (“PM2.5”) which are common air pollutants in urban areas where airports are often located. Second, the new rule will bring United States’ emissions standards into consistency with those established by the International Civil Aviation Organization (“ICAO”), see ICAO Annex 16, Vol. II, 2010 that the U.S. helped to develop and supports as part of the international process.
The rule contains six major provisions.
