(d) Each month a specific gravity correction shall be applied to measured volumes

based upon the specific gravity determined or sampled during that month. The

specific gravity to be used for such correction shall be determined at an

appropriate location from a continuous sampling device, by a gravitometer,

chromatograph or other device of standard manufacture and shall be either (1)

recorded using digital recorders or other mutually agreeable recording device in

which case an arithmetic average (to be determined during the period of time

during which flow was occurring at the location of the specific gravity recorder)

of such record shall be the specific gravity of the gas being measured, or (2)

used for flow computations in electronic flow computers in which case the value

of the specific gravity being measured will be used as appropriate in such

computations. If a continuous specific gravity measuring device is not installed

or available at an appropriate location, then specific gravity shall be determined

monthly from a continuous sampling device or by a mutually agreeable method.

(e) Each month a gross heating value correction shall be applied to measured

volumes based upon the gross heating value determined or sampled during that

month. The gross heating value shall be determined at an appropriate location

from a continuous sampling device, by a calorimeter, chromatograph or other

device of standard manufacture and shall be either (1) recorded using digital

recorders or other mutually agreeable recording device in which case arithmetic

average (to be determined during the period of time during which flow was

occurring at the location of the gross heating value recorder) of such record shall

be the gross heating value of the gas being measured, or (2) entered as an input

to electronic flow computers in which case the gross heating value being

measured will be used in the computation of the Btu content of the gas. If a

gross heating value measuring device is not installed or available at an

appropriate location, then the gross heating value shall be determined monthly

from a continuous sampling device or by a mutually agreeable method.
