RACM Exercise
Scenario: A local manufacturing plant is facing pressure from environmental regulators to reduce the amount of mercury being released into the surrounding water. The plant currently uses a process that releases a significant amount of mercury into wastewater.
Task:
- Identify two potential "RACM" that the plant could implement to reduce mercury discharge.
- Explain how each RACM would work and what its potential benefits and challenges might be.
- For each RACM, briefly consider the economic feasibility.
Exercice Correction
Here are two potential RACM's and their considerations:
RACM 1: Installing a Mercury Removal System
- How it works: A specialized filtration system would be installed to capture and remove mercury from the wastewater before it is discharged.
- Benefits: Significantly reduces mercury release into the environment, potentially meeting regulatory requirements.
- Challenges: High initial installation costs, potential for maintenance and operational costs.
- Economic Feasibility: The plant would need to weigh the cost of the system against potential fines for non-compliance, as well as the long-term environmental benefits.
RACM 2: Modifying the Production Process
- How it works: The plant could switch to a different production method or modify the existing process to minimize mercury use or release.
- Benefits: Could offer a long-term solution by reducing mercury generation at the source.
- Challenges: May require significant investment in research and development, potentially disrupting current operations.
- Economic Feasibility: The cost of process modification would need to be evaluated against the potential savings from reduced mercury use and avoidance of fines.
