From Aspects to Impacts
EPA Regions 9 & 10
and
The Federal Network for Sustainability
2
Objectives
After this discussion, you should be able to:
• Define an environmental impact
• Give examples of impacts from your facility
3
Overview
• Definition
• Examples
• Building an Inventory
4
Definition
An environmental impact is a change to the
environment, either adverse or beneficial,
wholly or partially resulting from an
organization’s activities, products, or
services.
5
Another Definition
The environment is the surroundings in which
an organization operates: including air,
water, land, natural resources, flora, fauna,
humans and their interactions.
(scale goes from within an organization
to the global system)
6
Environmental Impacts
• Measurable
• Regulated or below regulatory thresholds
• Removed from source
• Some are focus of current environmental
programs
• Others – no current program
7
Examples of Aspects & Impacts
• Vehicles emit exhaust
• Water leaks
• Fueling spills occur
• Containers not closed
• Noise from engine runup
• Lights, computers left on
at night
• Paper bleached w/ Cl
• Bicycles don’t emit
exhaust
• Sulfur oxides released
• Water resource depleted
• Stormwater contaminated
• Chemical may be spilled
• Hearing, sleep impaired
• Increased CO2, coal-fired
power plant emissions
• Dioxins created in W/W
• Air pollution reduced

EMS and Impacts
• Use the aspects register to identify impacts
• Environmental policy dictates which
aspects are significant
• EMS addresses significant aspects
• Document your process for identifying
aspects and impacts – look at your NEPA or
PPOA process
16
Impacts from Your Facility
• Prepare summary of environmental impacts
– Graphs make large amounts of data easy to
understand
– Document where the data came from
– Use to help build support for EMS
• If you don’t have the data, start collecting!
17
Summary
• Identification of environmental aspects and
impacts is a key part of an EMS
• Aspects and impacts arise from activities,
products, and services
• An EMS includes procedures for
identification and updating of aspects and
impacts

Editor's Notes

  1. Example of impact not typically part of an environmental program – paper consumption
  2. Examples of regulated, unregulated impacts Example of natural resource impact Examples of actual and potential impacts Example of human impacts Example of offsite impacts due to products used Example of positive environmental impact
