§ 80.82 Butane blending.
A refiner for any refinery that produces gasoline by blending butane with conventional gasoline or reformulated gasoline or RBOB may meet the sampling and testing requirements of subparts D and E of this part as follows:
(a) Any refinery that blends butane for which the refinery has documents from the butane supplier which demonstrate that the butane is commercial grade, as defined in paragraph (c) of this section, may demonstrate compliance with the standards in subparts D and E of this part based on the properties specified in paragraph (c) of this section, or the properties specified by the butane supplier.
(b)
(1) Any refiner that blends butane for which the refiner has documents from the butane supplier which demonstrate that the butane is non-commercial grade, as defined in paragraph (d) of this section, may demonstrate compliance with the standards in subparts D and E of this part based on the properties specified in paragraph (d) of this section, or the properties specified by the butane supplier, provided that the refinery:
(i) Conducts a quality assurance program of sampling and testing the butane obtained from each separate butane supplier which demonstrates that the butane has the properties specified in paragraph (d) of this section; and
(ii) The frequency of sampling and testing for the butane received from each butane supplier must be one sample for every 500,000 gallons of butane received, or one sample every three months, whichever is more frequent.
(2) Where test results indicate the butane does not meet the requirements in paragraph (b)(1) of this section, the refiner may:
(i) Blend the butane with conventional gasoline, or reformulated gasoline that has been downgraded to conventional gasoline, provided that the equivalent emissions performance of the butane batch, as determined using the provisions in § 80.101(g)(3), meets the refinery's standards under § 80.101;
(ii) Blend the butane with reformulated gasoline or RBOB, provided that the final batch of butane blended with reformulated gasoline or RBOB meets the per-gallon standards in § 80.41, as determined using the test methods in § 80.46.
(c) Commercial grade butane is defined as butane for which test results demonstrate that the butane is 95% pure and has the following properties:
olefins≤1.0 vol%
aromatics≤2.0 vol%
benzene≤0.03 vol%
sulfur≤140 ppm until December 31, 2003; ≤120 ppm in 2004; ≤30 ppm beginning January 1, 2005 and thereafter
(d) Non-commercial grade butane is defined as butane for which test results demonstrate the butane has the following properties:
olefins≤10.0 vol%
aromatics≤2.0 vol%
benzene≤0.03 vol%
sulfur≤140 ppm until December 31, 2003; ≤120 ppm in 2004; ≤30 ppm beginning January 1, 2005 and thereafter
(e)
(1) When butane is blended with conventional gasoline under this section during the period May 1 through September 15, the refiner shall demonstrate through sampling and testing, using the test method for Reid vapor pressure in § 80.46, that each batch of conventional gasoline blended with butane meets the volatility standards specified in § 80.27.
(2) Butane may not be blended with any reformulated gasoline or RBOB during the period April 1 through September 30, or with any reformulated gasoline or RBOB designated as VOC-controlled, under this section.
(f) When butane is blended with conventional gasoline or reformulated gasoline or RBOB under this section, product transfer documents which accompany the gasoline blended with butane must comply with all of the requirements of § 80.77 or § 80.106, as appropriate.
(g) Butane blended with reformulated gasoline or RBOB or conventional gasoline during a period of up to one month may be included in a single batch for purposes of reporting to EPA, however, commercial grade butane and non-commercial grade butane must be reported as separate batches.
(h) Where a refiner chooses to include butane blended with gasoline in the refinery's annual average compliance calculations:
(1) In the case of butane blended with conventional gasoline, the equivalent emissions performance of the butane must be calculated in accordance with the provisions of § 80.101(g)(3). For purposes of this paragraph (i)(1), the property values in § 80.82(c) or (d), as appropriate, may be used;
(2) In the case of butane blended with reformulated gasoline or RBOB, compliance with the reformulated gasoline standards may not be demonstrated using the provisions of this section;
(3) All butane blended into gasoline during the annual averaging period must be included in annual average compliance calculations for the refinery.
