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)

[-] SF6 and PFC bulk purchases (pounds)

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

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

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

~	SF6 and PFCs returned by equipment
users with or inside equipment (pounds)

|—| SF6 and PFCs stored in containers at the
beginning and end of the year (pounds).

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

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

~	SF6 and PFCs returned to suppliers (pounds)

~	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:

~	The mass of contents of the containers used
to fill equipment or cylinders at the
beginning and ending of each filling

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

~	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)

~	The emission factor values for each hose
and valve combination and the associated
valve fitting sizes and hose diameter

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

~	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):

~	The mean nameplate capacity for each	~ The total number of samples taken for
make, model, and group of conditions each make, model, and group of
(every five years) (pounds) conditions (every five years)

~	The upper and lower bounds on the 95
percent confidence interval for each
make, model, and group of conditions
(every five years) (pounds)

To determine installation losses:

~ SF6 and PFCs used to fill equipment at off-
site electric power transmission or
distribution facilities (pounds)

~ SF6 and PFCs used to charge the

equipment prior to leaving the electrical
equipment manufacturer facility (pounds)

~ The nameplate capacity of the equipment
installed at off-site electric power
transmission or distribution facilities
(pounds)
