__________ |
Note a: The maximum denaturant content
limit is changed from 4.76 v% to 5.00 v% to be consistent with ASTM
4806-06c |
Note b: The modification of ASTM D
512-89(1999), Procedure C consists of using 5 ml of sample diluted with 20 ml
of water in place of the 25 ml sample specified in the standard procedure. The
water shall meet ASTM D 1193-99, Type II. The volume of the sample prepared by
this modification will be slightly larger than 25 ml. To allow for the dilution
factor, report the chloride ion present in the fuel ethanol sample as the
chloride ion present in the diluted sample multiplied by five. |
Note c: The modification of ASTM D
1688-95, Test Method A (atomic absorption) consists of mixing reagent grade
ethanol (which may be denatured according to the U.S. Bureau of Alcohol,
Tobacco, and Firearms (BATF) of the U.S. Treasury Department Formula 3A or 30,
as set forth in 27 CFR
sections 21.35 and
21.57, as in effect April 1, 2001)
in place of water as the solvent or diluent for the preparation of reagents and
standard solutions. However, this must not be done to prepare the stock copper
solution described in 11.1 of ASTM D 1688-95. Because a violent reaction may
occur between the acid and the ethanol, use water, as specified, in the acid
solution part of the procedure to prepare the stock copper solution. Use
ethanol for the rinse and dilution only. |
(2)
Exemption.
(A)
Inapplicability of basic
standards. The standards in section (a)(1)(A) do not apply to a
quantity of denatured ethanol sold, offered for sale, supplied, or offered for
supply by a person who demonstrates as an affirmative defense that:
1. The person has complied with section
(c)(1)(B); and
2. He or she has
taken reasonably prudent precautions to assure that the denatured ethanol will
only be added to CARBOB which has been designed to be lawfully oxygenated with
denatured ethanol having the properties identified in the document provided
pursuant to section (c)(1)(B).
(B)
Substitute standards.
Starting December 31, 2003, no person shall sell, offer for sale, supply or
offer for supply denatured ethanol that is intended for blending with CARBOB or
California gasoline and is exempt pursuant to section (a)(2)(A), if the
denatured ethanol fails to comply with any of the properties identified in the
document provided pursuant to section (c)(1)(B).
(3)
Standards for products
represented as appropriate for use as a denaturant in ethanol.
(A) Except as otherwise provided in section
(a)(3)(B), starting December 31, 2003, no person shall sell, offer for sale,
supply or offer for supply a product represented as appropriate for use as a
denaturant in ethanol intended for blending with CARBOB or California gasoline,
if the denaturant has:
1. A benzene content
exceeding 1.10 percent by volume; or
2. An olefins content exceeding 10.0 percent
by volume; or
3. An aromatic
hydrocarbon content exceeding 35.0 percent by volume.
(B) A person may sell, offer for sale, supply
or offer for supply a product that is represented as only suitable for use as
an ethanol denaturant in ethanol intended for blending with CARBOB or
California gasoline if the denatured ethanol contains no more than a specified
percentage of the denaturant that is less than 5.00 percent. In this case, the
product must be prominently labeled as only lawful for use as a denaturant
where the denatured ethanol contains no more than the specified percentage of
the denaturant, and the seller, supplier or offeror must take reasonably
prudent precautions to assure that the denaturant will not be used in
concentrations greater than the specified percentage in ethanol intended for
blending with CARBOB or California gasoline. If these conditions are met, the
standards in section (a)(3)(A) for the denaturant will be adjusted by
multiplying the stated values by (5.00 / max.%), where "max.%" is the maximum
percentage by volume of denaturant specified for the denatured
ethanol.
(b)
Test Methods.
(1) In
determining compliance with the denatured ethanol standards in section
(a)(1)(A):
(A) The sulfur content of denatured
ethanol shall be determined by ASTM D 5453-93, which is incorporated herein by
reference.
(B) The aromatic
hydrocarbon, benzene and olefins content of denatured ethanol shall be
determined by sampling the denaturant and using the methods specified in
section 2263 to determine the content of
those compounds in the denaturant. The result will then be multiplied by
0.0500, except that where it is demonstrated that the denatured ethanol
contains less than 5.00 percent denaturant, the result will be multiplied by
the decimal fraction representing the percent denaturant; or
(C) Starting February 16, 2014, the aromatic
hydrocarbon and benzene content of denatured ethanol shall be determined by
ASTM D7576-10 (2010), which is incorporated herein by reference. Starting
February 16, 2014, the olefin content of denatured ethanol shall be determined
by ASTM D7347-07e1 (2007), which is incorporated herein by reference.
(D) In the event of any discrepancy between
results obtained by using sections
2262.9(b)(1)(B)
and 2262.9(b)(1)(C),
the results obtained by using section
2262.9(b)(1)(C)
shall take precedence.
(2) In determining compliance with the
denaturant standards in section (a)(3), the aromatic hydrocarbon, benzene and
olefins content of the denaturant shall be determined by the methods specified
in section
2263 for determining the content
of those compounds in gasoline.
(c)
Documentation required for the
transfer of denatured ethanol intended for use as a blend component in
California gasoline.
(1)
(A) Starting December 31, 2003, and except as
provided in section (c)(1)(B), on each occasion that any person transfers
custody or title of denatured ethanol intended for use as a blend component in
California gasoline, the transferor shall provide the transferee a document
that prominently states that the denatured ethanol complies with the standards
for denatured ethanol intended for use as a blend component in California
gasoline.
(B) Starting December 31,
2003, on each occasion that any person transfers custody or title of denatured
ethanol that is intended to be added to CARBOB designated for blending with
denatured ethanol exceeding any of the standards in section (a)(1)(A), the
transferor shall provide the transferee a document that prominently identifies
the maximum sulfur, benzene, olefin and aromatic hydrocarbon content of the
denatured ethanol, and states that the denatured ethanol may only be lawfully
added to CARBOB that is designated for blending with denatured ethanol having
such properties.
(2)
Starting December 31, 2003, any person who sells or supplies denatured ethanol
intended for use as a blend component in California gasoline from the
California facility at which it was imported or produced shall provide the
purchaser or recipient a document that identifies:
(A) The name and address of the person
selling or supplying the denatured ethanol, and identification of the person as
the producer or importer of the denatured ethanol; and
(B) With respect to imported denatured
ethanol, the name, location and operator of the facility(ies) at which the
ethanol was produced and at which the denaturant was added to the ethanol. As
an alternative, the document provided to the purchaser or recipient may
identify the date and time the ethanol was supplied from its import or
production facility, and state that the person selling or supplying the
denatured ethanol from the California facility at which it was imported or
produced maintains at the facility a list of the name, location, and operator
of all of the facilit(ies) at which the ethanol was produced and at which the
denaturant was added to the ethanol. In this case, the person shall for at
least two years maintain such information, and records identifying the entities
that produced the ethanol and added the denaturant in each batch of denatured
ethanol imported to the facility; during that two year period, the person shall
make the information and records, available to the Executive Officer within
five days after a request for the material.
