Licence conditions for pollution studies and reduction programs

Summary
 
Licence number: 12003
Title: EIP 8 - Gas Well Instrumentation Improvement Program
Start date: 12 Feb 2016
 
Licence Condition
Background Leak Detection and Repair Monitoring identified a number low level gas leaks from control instrumentation components at different gas wells. AGL use methane from the gas well to operate this equipment.  As some of these components are designed to reduce pressure, there can be small releases of methane to atmosphere.   During 2015 AGL undertook a trial using alternate technology at a number of well sites in the Camden Gas well field. A 12 volt battery powered air compressor was installed at these gas wells. Compressed air replaced the use of methane to operate the instrumentation equipment. The trial proved successful and AGL will install this technology across all production well sites during 2016.   The EPA considers this a positive outcome as air compressors to supply instrument air eliminates the need for AGL to use methane from the wells, and will contribute towards reducing fugitive emissions from wells. Program AGL proposes to install 12 volt air compressors according to the following schedule:
Whilst this schedule is implemented AGL will continue to operate its internal Leak Detection and Repair Program Survey for all operational and suspended wells. Completion Date: 31 December 2016
