(contamination),Toxic Substances (worker exposure, product use),Product Output,Location Mgmt. (odors, noise, aesthetics),,Environmental Outputs,Inputs,,Recyclables,ACTIVITY, PRODUCT OR SERVICE,21Nov24,78,STEP 3 – EVALUATE ASPECTS,The next step is evaluating and prioritizing aspects based on their actual or potential environmental impact This can be accomplished through “instincts”, risk matrices, etc. The key is to define what key items to consider in evaluating aspects and factor them into the decision process The result are your Significant Aspects,21Nov24,79,STEP 3 – EVALUATE ASPECTS,“Impact Factors” that many companies consider include: Severity of environmental impact Likelihood of environmental impact Potential for employee exposure Potential Liability Legal Concerns Etc.,21Nov24,80,STEP 3 – EVALUATE ASPECTS,Once you have identified, inventoried and evaluated your aspects, you can assign significance Aspects that do or may have a significant environmental impact, based on your impact factors should be considered significant Aspects that do not have a significant environmental impact are not significant Once again, some companies set numerical thresholds, some companies use their instincts,21Nov24,81,STEP 4 – PRIORITIZE ASPECTS,Significant aspects should be prioritized Priorities can be assigned based on: Impact scoring Risk Technological, operational and financial limitations Community good will Etc.,21Nov24,82,STEP 5 – UPDATE ASPECTS,Update your aspects Integrate aspects identification/evaluation into new process/chemical reviews Update aspects periodically to reflect site changes Review aspects at least annually to ensure that your results continue to reflect site conditions,21Nov24,83,A Sample Aspect and Impact Assessment Format,The Important “Step 1” Prepare the Process Flow of all activities taking into account input of material and output that associate with environmental aspect. Output (environmental aspects) shall be considered under: Normal condition: Operations are performed in accordance to plan or within the operation conditions. Abnormal condition: When there is deviation from plan or operating conditions. Emergency condition: Unusual conditions and hazardous situation which if not corrected or prevented could lead to significant environment impacts. Emergencies may result from natural or human causes.,21Nov24,84,A Sample Aspect and Impact Assessment Format,,Operating Condition (Normal, Abnormal or Emergency),21Nov24,85,A Sample Aspect and Impact Assessment Format,The environmental impact(s) arising from each of the aspect is determined based on (but not limited to) the following categories: Air pollution Water pollution Land pollution Resources depletion Noise pollution Global warming,21Nov24,86,A Sample Aspect and Impact Assessment Format,,21Nov24,87,A Sample Aspect and Impact Assessment Format,21Nov24,88,A Sample Aspect and Impact Assessment Format,Severity x Frequency x Detection/Controllability,Risk Priority Number (RPN) score of 8 or more denote significant environmental aspect amp。 impact.,If there are any legal regulations governing the environmental aspect amp。 impact, it automatically becomes significant.,Objectives and Target Setting should be prioritized for those Significant Aspects with Management Program implemention to reduce those Impacts to the environment.,21Nov24,89,A Sample Aspect and Impact Assessment Format,Formulating of the Significant Aspects and Impacts Register,An example from SG,21Nov24,90,Practice Make Perfect,Write down the work processes in your Department/ Area Use one process you identify and conduct the Risk Assessment and Environmental Aspect and Impact Assessment We will discuss…
