Electrical Equipment Manufacture or Refurbishment

Final Rule: Subpart SS, Mandatory Reporting of Greenhouse Gases

What Must Be Monitored for Each Manufacturer or Refurbisher of Electric Power
Transmission and Distribution Equipment Insulated with Sulfur Hexafluoride (SF6) and/or
Perfluorocarbons (PFCs) ?

                 Measure or estimate these parameters annually
                              (unless otherwise noted)
 D  SF6 and PFC bulk purchases
    (pounds)

 D  SF6 and PFCs sent off-site for
    destruction (pounds)

 D  SF6 and PFCs sent off-site to be
    recycled (pounds)

 D  SF6 and PFCs returned from off-site
    after recycling (pounds)

 D  SF6 and PFCs returned by
    equipment users with or inside
    equipment (pounds)
D  SF6 and PFCs stored in containers at the
   beginning and end of the year (pounds)

D  SF6 and PFCs inside new equipment
   delivered to customers (pounds)

D  SF6 and PFCs in containers delivered to
   customers (pounds)

D  SF6 and PFCs returned to suppliers
   (pounds)

D  The nameplate capacity of the equipment
   delivered to customers with SF6 or PFCs
   inside, if different from the quantity of SF6
   and PFCs inside equipment delivered to
   customers (pounds)
 To determine losses during disbursement of SF6 or PFCs from containers to equipment or
 cylinder being filled:	
 D  The mass of contents of the
    containers used to fill equipment or
    cylinders at the beginning and
    ending of each filling

 D  The mass of the SF6 or PFC that has
    flowed through the flow meter
    during the filling event

 D  The mass of the SF6 or PFC emitted
    downstream of the flow meter
    (emissions from hoses or other flow
    lines that connect the container to
    the equipment that is being filled)
D  The emission factor values for each hose
   and valve combination and the associated
   valve fitting sizes and hose diameter

D  The total number of fill operations for each
   hose and valve combination

D  SF6 or PFC emissions that occur as a result
   of unexpected events or accidental losses,
   such as a malfunctioning hose or leak in the
   flow line, during the filling of equipment or
   containers for disbursement (pounds)

 If using the assumption that the mass SF6 or the PFC disbursed to customers in new equipment
 is equal to the equipment's nameplate capacity (or partial shipping charge):	
 D  The mean nameplate capacity for
    each make, model, and group of
    conditions (every five years)
    (pounds)

 D  The upper and lower bounds on the
    95 percent confidence interval for
    each make, model, and group of
    conditions (every five years)
    (pounds)
D   The total number of samples taken for each
    make, model, and group of conditions
    (every five years)
 To determine installation losses:
 D  SF6 and PFCs used to fill equipment
    at off-site electric power
    transmission or distribution facilities
    (pounds)

 D  SF6 and PFCs used to charge the
    equipment prior to leaving the
    electrical equipment manufacturer
    facility (pounds)
D   The nameplate capacity of the equipment
    installed at off-site electric power
    transmission or distribution facilities
    (pounds)
