Wash. Rev. Code § 78.52.140
The use of gas from a well producing gas only, or from a well which is primarily a gas well, for the manufacture of carbon black or similar products predominantly carbon, is declared to constitute waste prima facie, and such gas well shall not be used for any such purpose unless it is clearly shown, at a public hearing to be held by the department, on application of the person desiring to use such gas, that waste would not take place by the use of such gas for the purpose or purposes applied for, and that gas which would otherwise be lost is not available for such purpose or purposes, and that the gas to be used cannot be used for a more beneficial purpose, such as for light or fuel purposes, except at prohibitive cost, and that it would be in the public interest to grant such permit. If the department finds that the applicant has clearly shown a right to use such gas for the purpose or purposes applied for, it shall issue a permit upon such terms and conditions as may be found necessary in order to permit the use of the gas, and at the same time require compliance with the intent of this section.
