Listing of certain unregulated pollutants - (a) **Radioactive pollutants, cadmium, arsenic, and polycyclic organic matter—** Not later than one year after August 7, 1977 (two years for radioactive [pollutants](/usc/42/1397h.md?p=c-4)) and after notice and opportunity for public hearing, the [Administrator](/usc/42/7602.md?p=a) shall review all available relevant information and determine whether or not emissions of radioactive [pollutants](/usc/42/1397h.md?p=c-4) (including [source material](/usc/42/2014.md?p=z), [special nuclear material](/usc/42/2014.md?p=aa), and byproduct material), cadmium, arsenic and polycyclic organic matter into the ambient air will [cause](/usc/42/9908.md?p=c-2), or contribute to, air pollution which may reasonably be anticipated to endanger public health. If the [Administrator](/usc/42/7602.md?p=a) makes an affirmative determination with respect to any such substance, he shall simultaneously with such determination include such substance in the list published under section [7408(a)(1)](/usc/42/7408.md?p=a-1) or [7412(b)(1)(A)](/usc/42/7412.md)[^1] of this title (in the case of a substance which, in the judgment of the [Administrator](/usc/42/7602.md?p=a), [causes](/usc/42/9908.md?p=c-2), or contributes to, air pollution which may reasonably be anticipated to result in an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness), or shall include each [category](/usc/42/1395w–4.md?p=j-1) of [stationary sources](/usc/42/7411.md?p=a-3) emitting such substance in significant amounts in the list published under [section 7411(b)(1)(A) of this title](/usc/42/7411.md?p=b-1-A), or take any combination of such actions. - (b) **Revision authority—** Nothing in [subsection (a)](#a) shall be construed to affect the authority of the [Administrator](/usc/42/7602.md?p=a) to revise any list referred to in [subsection (a)](#a) with respect to any substance (whether or not enumerated in [subsection (a)](#a)). - (c) **Consultation with Nuclear Regulatory Commission; interagency agreement; notice and hearing—** - (1) Before listing any [source material](/usc/42/2014.md?p=z), special nuclear,[^2] or byproduct material (or component or derivative thereof) as provided in [subsection (a)](#a), the [Administrator](/usc/42/7602.md?p=a) shall consult with the Nuclear Regulatory [Commission](/usc/42/2000ff.md?p=1). - (2) Not later than six months after listing any such material (or component or derivative thereof) the [Administrator](/usc/42/7602.md?p=a) and the Nuclear Regulatory [Commission](/usc/42/2000ff.md?p=1) shall enter into an interagency [agreement](/usc/42/1320b–8.md?p=a-3-A) with respect to those sources or [facilities](/usc/42/11049.md?p=4) which are under the jurisdiction of the [Commission](/usc/42/2000ff.md?p=1). This [agreement](/usc/42/1320b–8.md?p=a-3-A) shall, to the maximum extent practicable consistent with this chapter, minimize duplication of effort and conserve administrative resources in the establishment, implementation, and enforcement of [emission limitations](/usc/42/7602.md?p=k), [standards](/usc/42/1320d.md?p=7) of performance, and other requirements and authorities (substantive and procedural) under this chapter respecting the emission of such material (or component or derivative thereof) from such sources or [facilities](/usc/42/11049.md?p=4). - (3) In case of any [standard](/usc/42/1320d.md?p=7) or [emission limitation](/usc/42/7602.md?p=k) promulgated by the [Administrator](/usc/42/7602.md?p=a), under this chapter or by any [State](/usc/42/7602.md?p=d) (or the [Administrator](/usc/42/7602.md?p=a)) under any [applicable implementation plan](/usc/42/7602.md?p=q) under this chapter, if the Nuclear Regulatory [Commission](/usc/42/2000ff.md?p=1) determines, after notice and opportunity for public hearing that the application of such [standard](/usc/42/1320d.md?p=7) or limitation to a source or [facility](/usc/42/11049.md?p=4) within the jurisdiction of the [Commission](/usc/42/2000ff.md?p=1) would endanger public health or safety, such [standard](/usc/42/1320d.md?p=7) or limitation shall not apply to such [facilities](/usc/42/11049.md?p=4) or sources unless the President determines otherwise within ninety days from the date of such finding. ## Footnotes [^1]: See References in Text note below.
