CO HB1110

Eliminates the special fuel tax exemption for liquefied petroleum gas (LPG) and natural gas vehicles that previously paid only annual decal fees, replacing it with graduated excise tax rates from 2014-2019 that are lower than the previous 20.5 cents per gallon rate.

Establishes new excise tax rates for compressed natural gas (3¢-18.3¢ per gallon), liquefied natural gas (3¢-12¢ per gallon), and liquefied petroleum gas (3¢-13.5¢ per gallon) over the 2014-2019 period to reflect differences in fuel energy content.

Imposes a $50 annual registration fee on plug-in electric vehicles beginning January 1, 2014, with $30 directed to the Highway Users Tax Fund and $20 to the Electric Vehicle Grant Fund.

Requires the Division of Oil and Public Safety to promulgate rules for natural gas safety standards by January 1, 2014, covering inspections, specifications, labeling, and measurement requirements.

Mandates a joint report by January 1, 2017 evaluating the bill's effectiveness, analyzing alternative fuel impacts on roads and tax collection, and recommending a comprehensive fuel tax system.
