Map including surface and ground water monitoring locations
The Annual Air Emission Monitoring Report (AAEMR) is prepared and submitted each year with the Annual Return. The AAEMR includes tabulated and graphical results of all periodic and continuous monitoring data form the reporting period. Data is trended and compared against results from the previous four years. The AAEMR demonstrates that the air emissions and monitoring is representative of typical operating conditions at the Mt Piper Power Station. It demonstrates compliance with the Continuous Emission Monitoring System (CEMS) Quality Assurance and Control Procedures and summarises the total consumption of coal.
The Coal Ash Monitoring Report (CAMR) has been prepared in accordance with EPL 13007, Condition R4.4 and details the information required under Condition M9.1. The CAMR is included in Section 1.2 and Section 5 of the AAEMR.
