National Emergencies Act
>Congress has delegated at least 136 distinct statutory emergency powers to the President upon the declaration of an emergency. Only 13 require a declaration from Congress; the remaining 123 are invoked by an executive declaration with no Congressional input.[2]
>Emergency presidential powers are dramatic, and range from suspending all laws regulating chemical and biological weapons, including the ban on human testing (50 U.S.C. § 1515, passed 1969); to suspending any Clean Air Act implementation plan or excess emissions penalty upon petition of a state governor (42 U.S.C. (f) § 7410 (f), passed 1977); to authorizing and constructing military construction projects (10 U.S.C. (a) § 2808 (a), passed 1982) using any existing defense appropriations for such military constructions ($10.4 billion in FY2018[18]); to drafting any retired Coast Guard officers (14 U.S.C. § 331, passed 1963) or enlisted members (14 U.S.C. § 359, passed 1949) into active duty.
