(ii) A list of the affected sources or equipment for which the deviation occurred and the cause of the deviation, as reported under §63.5180(h) and (i).

(iii) An estimate of the quantity of each regulated pollutant emitted over any applicable emission limit in §63.5120 to this subpart or any applicable operating limit established according to §63.5121 to this subpart, and a description of the method used to calculate the estimate, as reported under §63.5180(h) and (i).
