Environmental impact
assessment, EMS
Environmental assessment (EA) is the assessment of
the environmental consequences (positive and negative) of a plan, policy,
program, or actual projects prior to the decision to move forward with the proposed
action. In this context, the term "environmental
impact assessment" (EIA)
is usually used when applied to actual projects by individuals or companies and
the term "strategic environmental assessment" (SEA) applies to
policies, plans and programmes most often proposed by organs of
state. Environmental assessments may be governed by rules
of administrative procedure regarding public participation and
documentation of decision making, and may be subject to judicial review.
The purpose of the assessment is to ensure that
decision makers consider the environmental impacts when deciding whether or not
to proceed with a project. The International Association for Impact Assessment
(IAIA) defines an environmental impact assessment as "the process of identifying,
predicting, evaluating and mitigating the biophysical, social, and other
relevant effects of development proposals prior to major decisions being taken
and commitments made". EIAs are unique in that they do not require
adherence to a predetermined environmental outcome, but rather they require
decision makers to account for environmental values in their
decisions and to justify those decisions in light of detailed environmental
studies and public comments on the potential environmental impacts
Environmental impact assessments
commenced in the 1960s, as part of increasing environmental awareness. EIAs
involved a technical evaluation intended to contribute to more objective
decision making. In the United States, environmental impact assessments
obtained formal status in 1969, with enactment of the National
Environmental Policy Act. EIAs have been used increasingly around the world.
The number of "Environmental Assessments" filed every year "has
vastly overtaken the number of more rigorous Environmental Impact
Statements (EIS)." An Environmental Assessment is a
"mini-EIS designed to provide sufficient information to allow the agency
to decide whether the preparation of a full-blown Environmental Impact
Statement (EIS) is necessary." EIA is an activity that is done to find out
the impact that would be done before development will occur.
General and industry specific
assessment methods are available including:
·
Industrial products –
Product environmental life cycle analysis (LCA) is used for
identifying and measuring the impact of industrial products on the environment.
These EIAs consider activities related to extraction of raw materials,
ancillary materials, equipment; production, use, disposal and ancillary
equipment.
·
Genetically modified plants –
Specific methods available to perform EIAs of genetically modified
organisms include GMP-RAM and INOVA.
·
Fuzzy logic – EIA methods need
measurement data to estimate values of impact indicators. However, many of the
environment impacts cannot be quantified, e.g. landscape quality, lifestyle
quality and social acceptance. Instead information from similar EIAs, expert
judgment and community sentiment are employed. Approximate reasoning methods
known as fuzzy logic can be used. A fuzzy arithmetic approach has also
been proposed and implemented using a software tool (TDEIA).
Follow-up
At the end of the project, an
audit evaluates the accuracy of the EIA by comparing actual to predicted
impacts. The objective is to make future EIAs more valid and effective. Two
primary considerations are:
·
Scientific – to examine the accuracy
of predictions and explain errors
·
Management – to assess the success of
mitigation in reducing impacts
Audits can be performed either as
a rigorous assessment of the null hypothesis or with a simpler
approach comparing what actually occurred against the predictions in the EIA
document.
After an EIA, the precautionary and polluter
pays principles may be applied to decide whether to reject, modify or
require strict liability or insurance coverage to a project, based on
predicted harms.
The Hydropower
Sustainability Assessment Protocol is a sector specific method for
checking the quality of Environmental and Social assessments and management
plans.
The Ministry of Environment, Forests and
Climate Change (MoEFCC) of India has been in a great effort in
Environmental Impact Assessment in India.
The main laws in action are the Water Act(1974),
the Indian Wildlife (Protection) Act (1972), the Air (Prevention and
Control of Pollution) Act (1981) and the Environment (Protection) Act
(1986),Biological Diversity Act(2002). The responsible body for this is
the Central Pollution Control Board. Environmental Impact Assessment (EIA)
studies need a significant amount of primary and secondary environmental data.
Primary data are those collected in the field to define the status of the
environment (like air quality data, water quality data etc.). Secondary data
are those collected over the years that can be used to understand the existing
environmental scenario of the study area. The environmental impact assessment
(EIA) studies are conducted over a short period of time and therefore the
understanding of the environmental trends, based on a few months of primary
data, has limitations. Ideally, the primary data must be considered along with
the secondary data for complete understanding of the existing environmental
status of the area. In many EIA studies, the secondary data needs could be as
high as 80% of the total data requirement. EIC is the repository of one stop
secondary data source for environmental impact assessment in India.
The Environmental Impact Assessment (EIA)
experience in India indicates that the lack of timely availability of reliable
and authentic environmental data has been a major bottle neck in achieving the
full benefits of EIA. The environment being a multi-disciplinary subject, a
multitude of agencies are involved in collection of environmental data.
However, no single organization in India tracks available data from these
agencies and makes it available in one place in a form required by
environmental impact assessment practitioners. Further, environmental data is
not available in enhanced forms that improve the quality of the EIA. This makes
it harder and more time-consuming to generate environmental impact assessments
and receive timely environmental clearances from regulators. With this
background, the Environmental Information Centre (EIC) has been set up to serve
as a professionally managed clearing house of environmental information that
can be used by MoEF, project proponents, consultants, NGOs and other
stakeholders involved in the process of environmental impact assessment in
India. EIC caters to the need of creating and disseminating of organized
environmental data for various developmental initiatives all over the country.
EIC stores data in GIS format and makes it
available to all environmental impact assessment studies and to EIA
stakeholders in a cost effective and timely manner. So that we can manage that
in different proportions such as remedy measures etc.
The National Environmental Policy Act of
1969 (NEPA), enacted in 1970, established a policy of environmental impact
assessment for federal agency actions, federally funded activities or federally
permitted/licensed activities that in the U. S. is termed "environmental
review" or simply "the NEPA process." The law also created
the Council on Environmental Quality, which promulgated regulations to
codify the law's requirements. Under United States environmental
law an Environmental Assessment (EA) is compiled to determine the need for
an Environmental Impact Statement (EIS). Federal or
federalized actions expected to subject or be subject to significant
environmental impacts will publish a Notice of Intent to Prepare an EIS as soon
as significance is known. Certain actions
of federal agencies must be preceded by the NEPA process.
Contrary to a widespread misconception, NEPA does not prohibit the federal
government or its licensees/permittees from harming the environment, nor does
it specify any penalty if an environmental impact assessment turns out to be
inaccurate, intentionally or otherwise. NEPA requires that plausible statements
as to the prospective impacts be disclosed in advance. The purpose of NEPA
process is to ensure that the decision maker is fully informed of the
environmental aspects and consequences prior to making the final decision.
Environmental assessment
An environmental
assessment (EA) is an environmental analysis prepared pursuant to
the National Environmental Policy Act to determine whether a federal action
would significantly affect the environment and thus require a more
detailed Environmental Impact Statement (EIS). The certified
release of an Environmental Assessment results in either a Finding of
No Significant Impact (FONSI) or an EIS.
The Council on Environmental
Quality (CEQ), which oversees the administration of NEPA, issued
regulations for implementing the NEPA in 1979. Eccleston reports that the NEPA
regulations barely mention preparation of EAs. This is because the EA was
originally intended to be a simple document used in relatively rare instances
where an agency was not sure if the potential significance of an action would
be sufficient to trigger preparation of an EIS. But today, because EISs are so
much longer and complicated to prepare, federal agencies are going to great
effort to avoid preparing EISs by using EAs, even in cases where the use of EAs
may be inappropriate. The ratio of EAs that are being issued compared to EISs
is about 100 to 1.
Likewise, even the preparation of an accurate EA is
viewed today as an onerous burden by many entities responsible for the
environmental review of a proposal. Federal agencies have responded by
streamlining their regulations that implement NEPA environmental review, by defining
categories of projects that by their well understood nature may be safely
excluded from review under NEPA, and by drawing up lists of project types that
have negligible material impact upon the environment and can thus be exempted.
Content
The Environmental Assessment is a concise public
document prepared by the federal action agency that serves to:
1. briefly provide sufficient evidence and analysis
for determining whether to prepare an EIS or a Finding of No Significant Impact
(FONSI)
2. Demonstrate compliance with the act when no EIS is
required
3. facilitate the preparation of an EIS when a FONSI
cannot be demonstrated
The Environmental Assessment includes a brief
discussion of the purpose and need of the proposal and of its alternatives as
required by NEPA 102(2)(E), and of the human environmental impacts resulting
from and occurring to the proposed actions and alternatives considered
practicable, plus a listing of studies conducted and agencies and stakeholders
consulted to reach these conclusions. The action agency must approve an EA
before it is made available to the public. The EA is made public through
notices of availability by local, state, or regional clearing houses, often
triggered by the purchase of a public notice advertisement in a newspaper of
general circulation in the proposed activity area.

Procedure
The EA becomes a draft public document when notice
of it is published, usually in a newspaper of general circulation in the area
affected by the proposal. There is a 15-day review period required for an
Environmental Assessment (30 days if exceptional circumstances) while the
document is made available for public commentary, and a similar time for any
objection to improper process. Commenting on the Draft EA is typically done in
writing or email, submitted to the lead action agency as published in the
notice of availability. An EA does not require a public hearing for verbal
comments. Following the mandated public comment period, the lead action agency
responds to any comments, and certifies either a FONSI or a Notice of Intent
(NOI) to prepare an EIS in its public environmental review record. The
preparation of an EIS then generates a similar but more lengthy, involved and
expensive process.
Environmental impact statement
The adequacy of an environmental impact statement
(EIS) can be challenged in federal court. Major proposed projects have
been blocked because of an agency's failure to prepare an acceptable EIS. One
prominent example was the Westway landfill and highway development in
and along the Hudson Riverin New York City. Another prominent
case involved the Sierra Club suing the Nevada Department of
Transportation over its denial of the club's request to issue a
supplemental EIS addressing air emissions of particulate matter and
hazardous air pollutants in the case of widening U.S. Route
95 through Las Vegas. The case reached the United States
Court of Appeals for the Ninth Circuit, which led to construction on the
highway being halted until the court's final decision. The case was settled
prior to the court's final decision.
Several state governments that have
adopted "little NEPAs," state laws imposing EIS requirements for
particular state actions. Some of those state laws such as the California
Environmental Quality Act refer to the required environmental impact study
as an environmental impact report.
This variety of state requirements produces
voluminous data not just upon impacts of individual projects, but also in
insufficiently researched scientific domains. For example, in a seemingly
routine Environmental Impact Report for the city of Monterey,
California, information came to light that led to the official federal
endangered species listing of Hickman's potentilla, a rare
coastal wildflower.
Transboundary
application
Environmental threats do not respect national
borders. International pollution can have detrimental effects on the
atmosphere, oceans, rivers, aquifers, farmland, the weather and
biodiversity. Global climate change is transnational. Specific pollution threats
include acid rain, radioactive contamination, debris in outer
space, stratospheric ozone depletion and toxic oil spills.
The Chernobyl disaster, precipitated by a nuclear accident on
April 26, 1986, is a stark reminder of the devastating effects of transboundary
nuclear pollution.
Environmental protection is inherently a
cross-border issue and has led to the creation of transnational regulation via
multilateral and bilateral treaties. The United Nations Conference on the
Human Environment (UNCHE or Stockholm Conference) held
in Stockholm in 1972 and the United Nations Conference on the
Environment and Development (UNCED or Rio Summit, Rio Conference, or Earth
Summit) held in Rio de Janeiro in 1992 were key in the creation of
about 1,000 international instruments that include at least some provisions
related to the environment and its protection.
The United Nations Economic Commission for
Europe's Convention on Environmental Impact Assessment in a Transboundary
Context was negotiated to provide an international legal framework for
transboundary EIA.
However, as there is no universal legislature or
administration with a comprehensive mandate, most international treaties exist
parallel to one another and are further developed without the benefit of
consideration being given to potential conflicts with other agreements. There
is also the issue of international enforcement. This has led to
duplications and failures, in part due to an inability to enforce agreements.
An example is the failure of many international fisheries regimes to restrict
harvesting practises. Application shall be achieved by the willing of
counties authorities. / Aphro10
Criticism
EIA is used
as a decision aiding tool rather than decision making tool. There is growing
dissent about them as their influence on decisions is limited. Improved
training for practitioners, guidance on best practice and continuing research
have all been proposed.
EIAs have been criticized for excessively limiting
their scope in space and time. No accepted procedure exists for determining
such boundaries. The boundary refers to ‘the spatial and temporal boundary of
the proposal’s effects’. This boundary is determined by the applicant and the
lead assessor, but in practice, almost all EIAs address only direct and immediate
on-site effects.
Development causes both direct and indirect
effects. Consumption of goods and services, production, use and disposal of
building materials and machinery, additional land use for activities of
manufacturing and services, mining and refining, etc., all have environmental
impacts. The indirect effects of development can be much higher than the direct
effects examined by an EIA. Proposals such
as airports or shipyards cause wide-ranging national and
international effects, which should be covered in EIAs.
Broadening the scope of EIA can benefit the
conservation of threatened species. Instead of concentrating on the project
site, some EIAs employed a habitat-based approach that focused on much
broader relationships among humans and the environment. As a result,
alternatives that reduce the negative effects to the population of whole
species, rather than local subpopulations, can be assessed.
Little attention is given to the systematic
identification and assessment of uncertainties in environmental studies which
is critical in situations where uncertainty cannot be easily reduced by doing
more research.
Need to consider uncertainty at all stages of the
decision-making process. In such a way decisions can be made with confidence or
known uncertainty. These proposals are justified on data that shows that
environmental assessments fail to predict accurately the impacts observed.
Eevidence of the intrinsic uncertainty attached to
EIAs predictions from a number of case studies worldwide. The gathered evidence
consisted of comparisons between predictions in EIAs and the impacts measured
during, or following project implementation. In explaining this trend, Highlighted
major causes are project changes, modelling errors, errors in data and
assumptions taken and bias introduced by people in the projects analyzed.
Environmental management system (EMS)
Environmental management
system (EMS) refers to the
management of an organization's environmental programs in a
comprehensive, systematic, planned and documented manner. It includes the
organizational structure, planning and resources for developing, implementing
and maintaining policy for environmental protection.
More formally, EMS is "a system and database
which integrates procedures and processes for training of personnel,
monitoring, summarizing, and reporting of specialized environmental performance
information to internal and external stakeholders of a firm".
The most widely used standard on which an EMS is
based is International Organization for Standardization (ISO)
2004. Alternatives include the EMAS.
An environmental management information system
(EMIS) or Environmental Data Management System (EDMS) is an information
technology solution for tracking environmental data for a
company as part of their overall environmental management system.
Goals
The goals of EMS are to increase compliance and
reduce waste:
·
Compliance is the act of reaching and
maintaining minimal legal standards. By not being compliant, companies may face
fines, government intervention or may not be able to operate.
·
Waste reduction goes beyond compliance to
reduce environmental impact. The EMS helps to develop, implement, manage,
coordinate and monitor environmental policies. Waste reduction begins at the
design phase through pollution prevention and waste minimization. At the end of
the life cycle, waste is reduced by recycling.
To meet these goals, the selection of environmental
management systems is typically subject to a certain set of criteria: a proven
capability to handle high frequency data, high performance indicators,
transparent handling and processing of data, powerful calculation engine,
customised factor handling, multiple integration capabilities, automation of
workflows and QA processes and in-depth, flexible reporting.
Features
An environmental management system (EMS):
·
Serves as a tool, or process, to improve
environmental performance and information mainly "design, pollution
control and waste minimization, training, reporting to top management, and the
setting of goals"
·
Provides a systematic way of managing an
organization’s environmental affairs
·
Is the aspect of the organization’s overall
management structure that addresses immediate and long-term impacts of its
products, services and processes on the environment. EMS assists with planning,
controlling and monitoring policies in an organization.
·
Gives order and consistency for organizations to
address environmental concerns through the allocation of resources, assignment
of responsibility and ongoing evaluation of practices, procedures and processes
·
Creates environmental buy-in from management and
employees and assigns accountability and responsibility.
·
Sets framework for training to achieve objectives
and desired performance.
·
Helps understand legislative requirements to better
determine a product or service's impact, significance, priorities and
objectives.
·
Focuses on continual improvement of the system and
a way to implement policies and objectives to meet a desired result. This also
helps with reviewing and auditing the EMS to find future opportunities.
·
Encourages contractors and suppliers to establish
their own EMS.
·
Facilitates e-reporting to federal, state and
provincial government environmental agencies through direct upload.
EMS Model
The PDCA cycle
An EMS follows
a Plan-Do-Check-Act, or PDCA, Cycle. The diagram shows the process of
first developing an environmental policy, planning the EMS, and then
implementing it. The process also includes checking the system and acting on
it. The model is continuous because an EMS is a process of continual
improvement in which an organization is constantly reviewing and revising the
system.
This is a model that can be used
by a wide range of organizations — from manufacturing facilities to service
industries to government agencies.
Accreditation
Environmental Data Management Systems (EDMS) can be
accredited under the UK Environment Agency's Monitoring Certification
Scheme (MCERTS) for Performance standards and test procedures.
Other
meanings
An EMS
can also be classified as
·
a system which monitors, tracks and reports
emissions information, particularly with respect to
the oil and gas industry. EMSs are
becoming web-based in response to the EPA's
mandated greenhouse gas (GHG) reporting rule, which allows for
reporting GHG emissions information via the internet.
·
a centrally controlled and often automated network
of devices (now frequently wireless
using z-wave and zigbee technologies) used to control the
internal environment of a building. Such a system namely acts as an interface
between end user and energy (gas/electricity) consumption.
