Working together, the NMMA and the ABYC have
proposed an industry specification for installing carbon
canisters and pressure relief systems, which the EPA and
CARB have accepted. The actual, detailed ABYC
specification is in development. Builders will be asked to
demonstrate that their products are built in accordance
with these specifications in order to obtain NMMA
certification. This will demonstrate to the EPA & CARB
that a boat is in compliance. Representatives from boat
& engine builders, tank, fill, valve and canister
manufacturers, test labs and the U.S. Coast Guard are
among the authors of the new specifications.
Refueling vapors bypass canister and vent through a vented
fill to the fuel pump. This line is then closed with a sealed cap
after refueling and diurnal vapors are forced through the
canister. This approach provides the least restriction during
refueling.
