Attachment 10-Air Quality and Odour Assessment · MCU23/0078

 Impact risk/odour control level                                                      Odour control
                                                                                      requirement
 3.   A filter comprising activated carbon where odorous components adhere to the
      carbon surface.
 4.   Counteractant and neutralising agents are incorporated into the air stream.
      Neutralising agents react with odorous molecules rendering it non-odorous.
      Counteracting agents reduce response to the odour by the human nose by
      reducing the perceived intensity.
 5.   UV converts oxygen in ambient air to the highly reactive ozone which oxidises
      odorous compounds.



◼     Stage 3: Monitoring and Control
The purpose of establishing a monitoring and control program is to maintain updated information about the
status of the air and odour control measures. It evaluates the actual performance of these measures against
the objective of preventing, reducing, and controlling emissions, and thereby providing insights for updating
any actions. The following are the suggested contents of the monitoring and control program:
         Description of the control measures taken and location of these control points
         Definition of compliance indicators against which odour control measures will be assessed for
          adequacy
         Documentation of control and monitoring procedures
         Training and competencies of team roles
         Assignment of responsibility for monitoring and control
The following are the proposed methodologies for monitoring and control:
         Determine restaurants that are significant sources of emissions by evaluating emission characteristics
         Verify and control compliance with good operational practices by evaluating standard operating
          procedures and maintenance plans of restaurants
         Evaluate operational emission reduction or removal processes of control equipment through
          operational parameters and procedures, removal efficiencies, and maintenance plans
         If required and complaints arise, investigate sources, and monitor concentrations, impacts, and
          exposure in receptors
At a minimum, monitoring and control should include the following components:
         Procedure for the monitoring of undesirable emissions and odour levels
         Review of control measures and efficiency of odour control equipment
         Proposed actions to address potential issues


◼     Stage 4: Contingency Program
The last stage is the contingency program which describes a course of action to be taken under unexpected
scenarios.
         Define possible origin of potential and exceptional issues such as operational failures
         Define the scope of the contingency program which includes the goals, responsible team for
          complying and executing the program, timeframes to comply with the contingency measures,
          communication channels among others
         Identify risk factors in odour control measures, its consequences or impacts, and alternative solutions
         Define contingency measures to be implemented for appropriate and/or immediate actions
