OAR 340-258-0120
Oxygenated Gasoline: Sampling and Testing for Oxygen Content

(1)

To determine compliance with the requirements of OAR 340-258-0110 (Oxygenated Gasoline: Purpose and General Requirements) through 340-258-0310 (Oxygenated Gasoline: Contingency Provision for Carbon Monoxide Nonattainment Areas), the oxygen content of gasoline must be determined by:

(a)

Sampling, using the sampling methods specified in 40 CFR 80, Appendix D, as amended through July 1, 1991, the provisions of which are incorporated by reference in this rule, to obtain a representative sample of the gasoline to be tested;

(b)

Testing, using the test method specified in ASTM 4815-89 or other test methods determined by the Department and EPA as being equivalent, to determine the mass concentration of each oxygenate in the gasoline sampled; and

(c)

Oxygen content calculations that are made as follows: Calculate the oxygen content of the gasoline sampled by multiplying the volume concentration of each oxygenate in the gasoline sampled by the oxygen molecular weight contribution of the oxygenate set forth in section (2) of this rule, with volume measurements adjusted to 60 degrees F.

(2)

The oxygen molecular weight contributions of an oxygenate approved for use under OAR 340-258-0110 (Oxygenated Gasoline: Purpose and General Requirements) through 340-258-0310 (Oxygenated Gasoline: Contingency Provision for Carbon Monoxide Nonattainment Areas) are set out in Table A.
