1987—Pub. L. 100–42 substituted “Coal capability of new electric powerplants; certification of compliance” for “New electric powerplants” in section catchline and amended text generally. Prior to amendment, text read as follows: “Except to such extent as may be authorized under part B—

“(1) natural gas or petroleum shall not be used as a primary energy source in any new electric powerplant; and

“(2) no new electric powerplant may be constructed without the capability to use coal or any other alternate fuel as a primary energy source.”
