"This Plan is submitted pursuant to ATC No. special condition 18. A-815, special condition 18. The Plan covers abatement procedures that will be employed during the drilling testing of True/Mid-Pacific Geothermal Well A1-1 and subsequent wells. Operations will be employed to treat and maintain H2S emissions below 8.5 lbs/hr in compliance with the ATC. Abatement practices presented in this plan have been adopted from existing plans commonly utilized in The Geysers Geothermal Field in California. SPE Paper 7882 is the primary reference for the abatement theory. Caustic (sodium hydroxide, NaOH) will be used to treat the H2S produced from the geothermal well because caustic has a high affinity for hydrogen sulfide. Brewer Chemical Company has been contacted, and they have provided assurance that caustic is available on the Big Island in the necessary quantities. Brewer has a bulk terminal in Hilo with approximately 100,000 gallons of storage capacity. Brewer will deliver caustic to the drill site in a 50% solution in 3500 gallon tanker trucks. In addition to caustic, hydrogen peroxide is sometimes used to convert the sodium sulfide into sodium sulfate. Hydrogen peroxide does not react directly with H2S, rather it tranforms the treated compound to a more stable form. Peroxide will not be used unless it becomes necessary. Brewer Chemical will also supply the peroxide if it is needed."
