A: Yes. Commercial operation is expected to commence in the autumn of 2017.
A: Dublin Waste to Energy Facility is a state-of-the-art plant with thousands of automated systems and processes. In order to ensure reliable operations, the facility will undergo extensive testing of all systems during the commissioning phase. These include:
- Start-up and testing of line 1
- Turbine generator start-up and synchronization to the grid
- Start-up and testing line 2
- Resync turbine
- 48 hour pre test
- 30 day demonstration test
A: After a thorough investigation, it was determined that a gasket was installed improperly on doors leading to the fabric filter baghouse. This led to the release of lime-ash (mainly calcium hydroxide) through a small opening in the door seals which was contained inside the flue gas treatment area.
The contactor responsible for construction and commissioning, Hitachi Zosen Inova (HZI), has installed new parts and corrected the issue. The door and gasket also underwent further testing to ensure it is properly installed prior to restart.
This was a one-time event that was discovered during the commissioning and testing of the Dublin Waste to Energy Facility. The EPA has confirmed that there was no environmental impact and that there is no danger to the public as a result of this event.
A: The material was largely calcium hydroxide, also known as hydrated lime. It is used in the emissions control system to neutralize acid gases from the combustion process.
Calcium hydroxide is also commonly used in the making of many everyday products, including in food preparation.
As a precaution, since calcium hydroxide may have short term impacts such as irritation to the skin and respiratory tract, 10 contractors that were working in the area were driven to a nearby hospital for medical evaluation. They have all been released.
A: We are working closely with the EPA to ensure that the Dublin Waste to Energy Facility will operate to the highest international standards and to ensure the absolute safety of its workers and contractors on site. The matters that are the subject of the EPA action occurred during the early stages of commissioning, and EPA has since given its approval to resume commissioning activity.
We look forward to reaching a formal resolution with EPA in due course.
