A687.

...

If

the

coal

mine

and

the

are

separate

facilities

under

“facility” definition

in

CFR

98.6

the

meets

the

threshold,

as

defined

in

CFR

...

98.2,

...

then

...

the

mine

must

(1)

calculate

and

report

methane

liberation

according

to

FF-1

through

(2)

methane

and

CO2

emissions

according

to

equations

FF–7 and

FF-8,

...

respectively.

...

If

...

the

gas

is

transported

off–site for

destruction,

then

the

should

FF–5. Note that if the mine owns and operates any stationary combustion devices at the mine, the mine would report emissions from these combustion devices under Subpart C. However, the mine would not report emissions from stationary combustion devices located at a separate off–site facility that combusts gas from the mine.
