Understanding and Identifying Environmental Aspects and Impacts
What is Environmental Aspect
An
environmental aspect is any part of an
organization’s activities that can interact with the
environment, either positively or negatively. Or, simply put, the way a company’s activity, service,
or product impacts the environment.
This could be chemicals that are emitted into
the air from a vent during processes, or chemicals that could be expelled in wastewater. For example, presence of cleaning agent in wastewater from a dry-cleaning
service provider for big pharma which has a potential to contaminate water and
soil. The cleaning agent in wastewater is the environmental
aspect as the potential for water or soil pollution is the impact of the aspect
to the environment.
Also, consider
the use of resources that a
company’s processes utilize like water, electricity, fuels and other raw
materials, or the environmental effect of the amount of
waste/ waste streams they
dispose of or generate respectively.
Categories of Environmental
Aspects
The major
categories of environmental aspects
could include (but are not limited to):
· Emissions to air e.g., stack emissions, fume releases, powder/dust generation
· Wastes management (encompasses both hazardous and non-hazardous wastes from their generation to final disposal)
· Contamination of land from discharges to land e.g., material spillages or use of fertilizers, sludges etc.
· Consumption of natural resources and raw materials like water, energy, fossil fuels (oils, diesel, petrol etc)
· Releases to water like wastewater/effluent discharges to wetlands, water bodies or to land seeping to groundwater reservoirs, fuel tankers bursting during transportation on water etc.
· Other environmental issues particular to the locality and community (noise, odours, heat/radiation and biodiversity)
By reviewing the processes against each of these
categories, it becomes much easier to visualize how processes of an organization can
affect the environment, and this is what the environmental aspects are.
How to identify
Environmental Aspects
The following steps
should help in identifying an organization’s environmental aspects
1. Define the scope of Environment Management System (EMS)
Firstly, lets define management
system. A management system is the way in which an organization manages the
inter-related parts of its business in order to achieve its objectives. Therefore,
an EMS scope refers to the spatial, functional and organizational company
boundaries to which the EMS shall apply.
To define the EMS scope,
the following should be considered
· Organizational unit(s), function(s), and physical boundaries like departments and sections.
· Relevant internal and external issues that significantly influence intended outcomes - external issues include proximity to protected areas, wetlands or swamps and waterbodies, parks, forests or community around the establishment.
· Legal and other obligations derived from the expectations of interested parties must be taken into consideration when you identify environmental aspects and impacts.
2. Identify the activities, services and products of the
organization
Identify all
activities, services, and products that fall within the units and functions
identified above keeping in mind those that are outsourced externally.
Being able to
understand the main terms is key to identifying them.
· An activity is a part of the core business (e.g., production process steps)
· Service means an auxiliary service that supports core activities (e.g., boilers, heating & cooling, maintenance)
· A product is the goods you offer for market. An environmental aspect of the product could be, e.g., excessive packaging of the product, or level of recyclability of the product at the end of its lifecycle.
3. Identify the environmental aspects associated with the
above activities, service and products
Aspects can be divided
into direct and indirect.
Direct
environmental aspects are
associated with activities, products, and services of the organization itself,
over which it has direct management control e.g., how wastes are managed on the
site or the organization’s premises.
Indirect
environmental aspects are
associated with activities that an organization has no direct control over or
outsourced services. e.g., how subcontractor manages waste on the organization’s
site, chain-controlled aspects, customer-controlled aspects. This especially
useful for non-industrial organizations.
As discussed above, environmental
aspects for a specified activity/product/ service must include:
· Associated activity/sub-activity with the product/ process
· Contribution to the process (raw material, energy resources, other utilities, etc.)
· Process output (product, waste, heat/radiation/ illumination, etc.)
· Emissions into the atmosphere (flue gases, fumes, particulate, noise, fugitive emissions, VOC, etc.)
· Waste generation and disposal, land contamination, and outfall (Effluent) releases (liquid waste, chemical spillage, leakage, oil spills, etc.)
· Aspect resulting from the process/activity
· The consequences of the aspects (air, water, land, noise pollution, resource depletion).
· Operation condition (Normal, Abnormal, emergency)
4. Assess the risks presented to the environment by
aspects
This step helps identify the impacts/effects an aspect will have on the environment for example;
· Direct impacts occurring through direct interaction of an activity with an environmental, social, or economic component e., a discharge of any industry or an effluent from the Effluent Treatment Plant (ETP) into a river may lead to a decline in water quality in terms of high biological oxygen demand (BOD) or dissolved oxygen (DO) or rise of water toxins.
· Indirect impacts often produced away from or as a result of a complex impact pathway. The indirect impacts are also known as secondary or even third level impacts. For example, ambient air SO2 rise due to stack emissions may deposit on land as SO4 and cause acidic soils. Another example of indirect impact is the decline in water quality due to rise in temperature of water bodies receiving cooling water discharge from the nearby industry.
5. Evaluate the significant environmental aspects
From these activities,
products or services, and their impacts, identify those with significant
environmental aspects.
The purpose of the
evaluation of environmental aspects is focusing on what matters the most. Significant
environmental aspects are the focus of an organization’s environmental
management system.
Depending on type,
nature, and complexity of an organization, there are many techniques available
for conducting an evaluation to determine the significance of environmental
aspects. In assessing the significance, consider:
· Potential to cause environmental harm
· Size and frequency of the aspect
· Importance to the stakeholders of the organization
· Requirements of relevant environmental legislation
Establish criteria for
significance based on a systematic review of the organization’s environmental
aspects and their actual and potential impacts.
6. Manage/control significant environmental aspects and
their impacts
Every significant
aspect should be brought under control by establishing one or more of the
following controls:
· Identify the current or existing controls to reduce the risk or impact.
· Responsible person. Decide what further action is needed to control the residual risks, who needs to carry out the action, and when the action should be completed.
· Training plan or procedure, checklist and/or maintenance schedule.
The Level of control should
be appropriate to the nature and risk of the significant aspect.
7. Record the significant findings
Findings can be recorded
in an environmental aspect/impact register.

Conclusion
Identification and
evaluation of environmental aspects is the foundation for an environment
management system and helps make a better understanding of how an organization
interacts with environment.
