Study and Investigation of Uninstalled Aircraft Engines
Pub. L. 101–549, title II, § 233, Nov. 15, 1990, 104 Stat. 2529, provided that:
“(a) Study.—The Administrator of the Environmental Protection Agency and the Secretary of Transportation, in consultation with the Secretary of Defense, shall commence a study and investigation of the testing of uninstalled aircraft engines in enclosed test cells that shall address at a minimum the following issues and such other issues as they shall deem appropriate—
whether technologies exist to control some or all emissions of oxides of nitrogen from test cells;
the effectiveness of such technologies;
the cost of implementing such technologies;
whether such technologies affect the safety, design, structure, operation, or performance of aircraft engines;
whether such technologies impair the effectiveness and accuracy of aircraft engine safety design, and performance tests conducted in test cells; and
the impact of not controlling such oxides of nitrogen in the applicable nonattainment areas and on other sources, stationary and mobile, on oxides of nitrogen in such areas.
“(b) Report, Authority To Regulate.—
Not later than 24 months after enactment of the Clean Air Act Amendments of 1990
[Nov. 15, 1990
], the Administrator
of the Environmental Protection Agency
and the Secretary of Transportation shall submit to Congress
a report of the study conducted under this section. Following the completion of such study, any of the States
may adopt or enforce any standard for emissions of oxides of nitrogen from test cells only after issuing a public notice stating whether such standards are in accordance with the findings of the study.”
