Air quality compliance improvements through operational management of air resources (OMAR)

Geothermal well fields and power plants require operational and emergency atmospheric venting. Venting activities are monitored for compliance with regulations which limit air pollutant emissions and Ambient Air Quality Standards (AAQS). Continuous compliance monitoring data which includes hydrogen sulfide (H2S) levels and meteorological conditions is only available moths after being compiled. In this paper an automated computerized system called OMAR is described in the following which checks data and allows users access to real-time and near real-time data reports. The data can then be used for managing necessary venting or other real-time data needs. The OMAR system hardware and software is descried and is in use at The Geysers and at the Coso KGRA geothermal developments in California. The system has been designed to assist developers, engineers, scientists, and the local air districts in their goal of maintaining ambient air quality within Federal, State and Local standards
