Even with added exceptions for high-;ow dispensers and
cold weather states, vocal industry associations stood ;rm against
the proposal. Upstream suppliers, retailers said, send to them
inventory with little or no ;ltration, leading to water or particulate contamination. Retailers also said the proposed change from
a 30-micron to 10-micron ;lter would be an economic burden
placed solely on endpoint retailers. The subsequent discussion
on techniques for fuel cleanliness turned argumentative. A few
regulators sided with station operators and requested their states
be added to the winter-exclusion list.
As for the vote, the larger delegate group voted overwhelmingly in favor of 10-micron ;lters. State representatives, however,
split evenly. To have passed the measure, both groups would had
to have approved it.
The retailers won this time, but the issue isn’t dead.
“Failing to pass,” according to the NCWM voting process, is
different than a defeat. As a result, the diesel dispenser ;lter
item may return to the 2017 agenda for another vote if it is not
withdrawn in January during the NCWM Interim Meeting in
Two-minute warning. NCWM delegates passed
another rule that could affect anyone dealing with retail
dispensers that accept credit card authorizations.
The rule requires a retail dispenser to reset within
two minutes of authorization if the dispenser also has
not been activated. The idea is to prevent fraud should
someone swipe his or her payment card but subsequently
not fuel up.
The rule prompts a theoretical conundrum. A procedure used by the National Type Evaluation Program
(NTEP) allows up to three minutes for a dispenser to
reset. On Jan. 1, retail motor fuel dispensers in operation
could be NTEP-certi;ed yet noncompliant with the new
Water in storage tanks. Numerous reports link water
contamination to microbial growth in ultralow-sulfur diesel (ULSD). As sulfur content in the U.S. diesel supply has
dropped steadily, preventing water in tanks has become
more critical. Corrosion connected to water contamination damages delivery and storage systems, and it leads to
particulate contamination that wreaks havoc on the ;nely
tuned injection systems of modern vehicles.
As a response, the NCWM 2017 agenda will feature
a suggested change to the amount of water allowed in
retail motor fuel storage tanks. The current code in NIST
Handbook 130 speci;es two rules regarding water in
motor fuel storage tanks, depending on the fuel being
stored. The current code states that straight gasoline
or diesel may have up to 1 inch of water, and gasoline
blended with ethanol, biodiesel or aviation fuels may contain up to one-fourth inch of water in tanks. The NCWM
proposal being discussed would streamline the regulation
and limit all retail motor fuel storage tanks to one-fourth
inch of water, regardless of fuel composition.
PEI will continue to report on these issues, NCWM
voting results and any new business that might be of interest to PEI members.
