Q642. Our facility owns SF6- or PFC-containing equipment, but we are not an electric power transmission or distribution entity as defined in 98.308. Are we required to report emissions under subpart DD?

 

A642. It is possible that you would be required to report emissions under subpart DD, but the criteria that must be satisfied significantly limit the number of situations where anyone other than an electric power transmission or transmission distribution entity will be required to report subpart DD emissions. If you are not an electric power transmission or transmission distribution entity, then subpart DD applies only if the total nameplate capacity of SF6 and PFC equipment at your facility (as facility is defined in 98.6) exceeds 17,820 pounds. For example, an iron and steel producer subject to subpart Q is required to report emissions under subpart DD only if the total nameplate capacity of SF6- and PFC-containing equipment that is owned by the iron and steel producer and that is located at that site exceeds 17,820 pounds. If subpart DD applies, then the iron and steel producer must register and report the DD equipment as a separate facility from the subpart Q facility and submit separate reports for each facility.
