- Q627. Is the electrical transmission equipment that is located within the plant boundary of a power plant included with the other transmission and distribution equipment that has a common owner and is between the power plant(s) and the customer?
- Q628. At what point during the year does the 17,820 pound threshold for the nameplate capacity of SF6- and PFC-containing equipment apply? Does equipment that has been sent offsite for reconditioning count toward the threshold?
- Q629. To what extent does a subpart DD facility include potential subpart C sources located in the same physical structure? Would it include sources using natural gas for comfort heating in warehouses and office complexes on the electric power system?
- Q630. If company A owns the substations 1, 3 and 5 and company B owns substations 2 and 4 located in ascending order in the same transmission line, how would the subpart DD facilities for companies A and B be configured?
- Q631. Should servicing inventory, such as pressurized cylinders and gas carts, be included in determining the applicablity of subpart DD with respect to the 17,820 pound threshold for the nameplate capacity of SF6- and PFC-containing equipment?
- Q632. Can an electricity generating and distribution company with 100-150 substations subject to subpart DD report SF6 emissions under one facility location? The company's power plants have been registered separately.
- Q641. Our utility owns power plants that are subject to Part 98 subpart D and 100-150 substations. Do we report SF6 and PFC emissions under subpart DD as a separate facility or together?
- 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?
- Q643. Should we report the SF6 and PFC emissions from a substation located at a power plant subject to subpart D under subpart DD? If so, would the SF6 and PFC emissions be reported under the same report as the subpart D emissions or as a separate report?
- Q644. At what point during the year does the reporting threshold apply for subpart DD?
- Q646. Our facility has SF6 gas cylinders. Do we include those in reporting under subpart DD?
- Q649. Do we include the quantity of SF6 contained in hermetically sealed equipment when determining applicability under subpart DD?
- Q831. Can "hermetically sealed-pressure switchgear" under Subpart DD in 40 CFR Part 98 be interpreted consistently with the definitions of "hermetically sealed gas-insulated switchgear" adopted by the Massachusetts and the California?
- Q852. What equipment should be included as new or retired equipment each year for Subpart DD?
