by industry groups, including INGAA,
claimed, " It is impracticable and
unrealistic for PHMSA to prescribe that
distribution service line piping begins at

Among the potential unintended
consequences of the provision, the
commenters pointed out that the
transmission operator would be required
to odorize the small amount of piping
between the first regulator and the
custody transfer point.
" Where farm tap piping is already being
odorized downstream, installing upstream
odorization adds no safety benefits and
creates practical challenges associated
with installing the new equipment and
ensuring the correct level of odorant, "
