motor fuel sold or offered for sale in this state to the most

recently adopted or amended petroleum standards on the date of the

sale by ASTM International.

(b)

The commission shall adopt rules to ensure that, except

as provided by Section 2310.2031, gasoline or gasoline blended with

ethanol that is sold or offered for sale in this state meets the

standard specification requirements applicable to the period and

region, as described in the most recent edition of ASTM

International's publication D4814, "Standard Specification for

Automotive Spark-Ignition Engine Fuel."

SECTION 4. The heading to Section 2310.203, Occupations

Code, are amended to read as follows:

(a) The department or an authorized representative of the

] standards
described
[
required
] by Section
2310.2016

[
2310.202
].

(c-1) The commission shall adopt rules regulating the

EXCEPTIONS TO MOTOR FUEL QUALITY STANDARDS.

(a)

Gasoline or gasoline blended with ethanol that is sold or

offered for sale in this state during periods when areas within this

state on either side of the meridian of 99° 00' west longitude line

on opposite sides of the line have different volatility classes

under the most recently adopted Schedule of U.S. Seasonal and

Geographic Volatility Classes in ASTM International's publication

D4814, "Standard Specification for Automotive Spark-Ignition

Engine Fuel," conforms with this chapter and commission rules if it

complies with the volatility class for either area.

(b)

Gasoline sold or offered for sale in this state conforms

with the Driveability Index provided in the Vapor Pressure and

Distillation Class Requirements in the most recently adopted

version of ASTM International's publication D4814, "Standard

Specification for Automotive Spark-Ignition Engine Fuel," if it

meets or exceeds vapor pressure and distillation class AAA, AA, or

A.

(c)

Gasoline blended with up to 15 volume percent ethanol is

granted a vapor pressure tolerance waiver of 1.0 pound per square

inch except for gasoline blends sold or offered for sale beginning

May 1 and ending October 1 each year in counties required to comply

with low emissions motor fuel standards.

(d)

Seasonal specifications for vapor pressure may be

extended for a maximum period of 15 days to allow for the

distribution of existing stocks. New stocks of a higher volatility

classification may not be offered for retail sale in this state

before the effective date of the higher volatility classification.

(e)

The vapor-to-liquid ratio specification under this

section does not apply to gasoline or gasoline ethanol blends.

(f)

This section may not be construed to interfere with

regulations for low emissions motor fuels adopted by this state to

comply with federal law.

SECTION 7. Section 2310.202, Occupations Code, is repealed.

SECTION 8. The changes in law made by this Act apply only to

a violation committed on or after the effective date of this Act. A

violation committed before the effective date of this Act is

governed by the law in effect when the violation was committed, and

the former law is continued in effect for that purpose. For

purposes of this section, a violation was committed before the

effective date of this Act if any element of the violation was

committed before that date.

SECTION 9. This Act takes effect immediately if it receives

a vote of two-thirds of all the members elected to each house, as

provided by Section 39, Article III, Texas Constitution. If this
