Environmental Impact Assessment Process for Changes to Aircraft Operations 

Purpose 
The purpose of this National Operating Standard (NOS) is to prescribe an 
environmental impact assessment process (the Assessment) that must be undertaken 
by Airservices, prior to the implementation of changes to aircraft operations.  
The main goals of the Assessment are to: 
• 
meet Airservices’ Legislative obligations to: 
◦ 
minimise significant environmental impacts resulting from any action, and 
ensure appropriate environmental assessments are undertaken, as 
required under the Environmental Protection and Biodiversity Conservation 
Act 1999
 (EPBC Act) 
◦ 
ensure air traffic management practices are conducted in a manner that  
protects the environment, as far as is practicable, as required under the 
Airservices Act 1995. 
• 
minimise Airservices business risks by maintaining effective stakeholder 
engagement and sound corporate citizenship in aircraft noise management 
• 
provide a standardised and rigorous approach to assessing the impacts of 
changes to aircraft operations, as a demonstration of organisational due diligence 
in environmental management. 
The overall outcome of the Assessment will be a defined environmental risk level and 
risk mitigation strategies for the proposed change, which must be either accepted or 
rejected by the ATC manager accountable for the change (such as the Executive 
General Manager, Service Delivery Line Manager or ATC Line Manager) and the 
manager who is implementing this change (e.g. Project Manager). Consequently, it is 
not the role of Environmental Specialists to accept or reject a proposal. The decision 
ultimately rests with the Change Manager, who is informed by the Assessment and the 
resulting risk determination  

Scope 
The Assessment applies to all Airservices proposed changes to air traffic management 
practices (Proposals) that may involve a change to aircraft operations. 
Proposals include, but are not limited to, the following changes: 
• 
A new, or amendment to an existing, instrument approach 
• 
A new, or amendment to an existing, flight path or air route 
• 
Re-classification of airspace 
• 
Change to preferred runways 
• 
Change in time of day of operation (e.g. amendments to tower hours of operation 
by Airservices Australia pursuant to the Freedom of Information Act 1982 (Cth)
– the time of day that a tower operates may alter the flight path used by aircraft) 
• 
A change that allows use of a flight path/airspace by a different type or number of 
aircraft. 
Note: 
A tactical decision of an air traffic controller to alter the track of an individual 
Released 
aircraft does not constitute a Proposal.

Environmental Impact Assessment Process for Changes to Aircraft Operations 

Principles 
4.1 
Proposals with ‘potential significant impact’ 
Any proposal that results in an EPBC assessment finding of ‘potential significant 
impact
1, shall be referred, by the EGM SE&A, to the Commonwealth environment 
portfolio Minister (the Environment Minister) for advice, (unless the Proponent decides 
not to proceed with the proposal).  
Once advice is received from the Environment Minister: 
• 
the Environment Minister’s advice shall be considered by the CEO and 
• 
the action taken (e.g. in relation to implementation of the proposal) shall be 
recorded, and if the Minister’s advice was not given effect, the reasons why, shall 
be documented and forwarded to the Environment Minister, by the CEO, in 
accordance with the EPBC Act. 
4.2 
All proposals 
All proposed changes to Airservices’ air traffic management practices that may affect 
aircraft operations shall: 
• 
be undertaken in accordance with this National Operating Standard (NOS) and 
associated documentation 
• 
be recorded in CIRRIS2 and Airservices National Request for Change (NRFC) 
register by the Change Manager3 
• 
be reassessed prior to implementation, if the proposal has already been impact 
assessed in accordance with this NOS and: 
◦ 
has subsequently been modified or  
◦ 
over twelve months has elapsed since the initial assessment process. 
by Airservices Australia pursuant to the Freedom of Information Act 1982 (Cth)
                                                 
1 It is Airservices position that an Airservices EPBC noise assessment should rarely result in a finding of ‘significant 
impact’ (as defined under the EPBC Act) as this is a decision that only the Environment Minister can make following their 
formal assessment of the proposal, and any Airservices noise impacts can be readily mitigated and are non permanent. 
The highest level of impact determined through the Airservices assessment should be a finding of ‘potential significant 
Released 
impact’. The final decision on actual significance (under the EPBC Act) will rest with the Environment Minister after 
formal advice is sought, and any required assessments are undertaken. 
2 CIRRIS replaced the ARMs database in 2012 
3 Throughout the document, where accountabilities are assigned to the Change Manager, these activities can be 
undertaken by delegates (such as a Change Coordinator), however the accountability to completion remains with the 
Change Manager.

Environmental Impact Assessment Process for Changes to Aircraft Operations 

Impact assessment process 
The Assessment is a staged process with defined ‘gates’ that must be passed through 
prior to Proposal implementation. There are three main elements of the Assessment as 
follows: 
• 
Initial Environmental Screening, Risk Assessment and Planning 
• 
EPBC Assessment and Referral Process 
• 
Environmental Business Risk Assessment and Management. 
This section describes key attributes of the above Assessment elements (including the 
basis for each assessment stage, key actions, responsibilities, and outcomes). This 
section should be read with reference to the Overall Assessment Process Flow 
Diagram (Appendix A) although key process flows are also included within the text 
where relevant. Relevant attributes of the Assessment stages are also summarised in 
Appendix B. 
5.1 
Initial environmental screening, risk assessment and planning 
These Assessment stages provide for an initial environmental impact screening by the 
Proponent on behalf of the Change Manager, the formation of the environmental 
change team involved in the change, and a draft risk assessment (to identify changes 
with an unacceptable level of risk and to assist in planning the level of work required in 
later stages). 
Key steps in this stage are further described in the following subsections. 
Refer to Figure 1 for a flow diagram of the Initial Environmental Screening, Risk 
Assessment and Planning Element.

Environmental Impact Assessment Process for Changes to Aircraft Operations 
5.1.1.2 Assessment 
basis 
Screening must be undertaken for all changes within the scope of this standard and is 
the first step in the Assessment.  
Screening considers a range of pre defined criteria that relate primarily to aircraft flight 
patterns (including location, altitude and communities over-flown). The screening 
criteria is included in Appendix C. As part of the screening an Initial Risk Assessment is 
also conducted. 
If the Screening result is:  
• 
TRUE for any criteria then further environmental assessment is not required. 
• 
FALSE for all criteria then further environmental assessments are required as 
documented in this standard.  
Screening is undertaken in CIRRIS and the outcome will determine whether the 
change can proceed or if further environmental assessment must be conducted as part 
of the change. 
The Environmental Services branch perform a quality assurance review of findings 
requiring no further environmental assessment, however the change can be 
implemented without this QA review being completed. If, during QA review, the 
assessment is believed to be incorrect, the change should not proceed without 
rescreening. If the change has already been implemented, then the Accountable ATC 
Manager (or delegate) will be informed and will determine if the associated risk level is 
acceptable (or if further assessments and/or changes are required). 
5.1.1.3 Required 
Actions 
The Proponent shall: 
• 
enter the proposal into CIRRIS and the Airservices’ NRFC register 
• 
undertake the Screening for Environmental Impact (using the environmental 
impact screening criteria – Appendix C) for all proposals in CIRRIS  
• 
once reviewed by the Change Manager, record in the NRFC (and where 
appropriate ARP), the screening result (including whether further Environmental 
Assessment is required). 
The Change Manager shall: 
• 
review the Screening for Environmental Impact in CIRRIS 
• 
inform Environmental Services (through CIRRIS) of the outcome 
• 
where required, seek advice from Environmental Services Branch about the 
screening process. 
The Environment Services Branch shall: 
by Airservices Australia pursuant to the Freedom of Information Act 1982 (Cth)
• 
for outcomes where no further environmental assessment is required: 
◦ 
conduct a quality assurance review of the Proponent’s determination 
against the Screening criteria (Appendix C) and any known environmental 
sensitivities (without detailed analysis at this stage) 
Released 
◦ 
notify the Change Manager where the screening outcome is not supported.

Outcomes of Initial ATS change screening stage 
• 
A screening result as to whether further environmental assessment is required. 
• 
If no further environmental assessment is required then the change can continue 
without any other assessment defined in this standard. 
• 
If further environmental assessment is required, then the ‘Environmental 
Assessment and Planning’ stage must be conducted. 
5.1.2 
Environmental assessment planning 
5.1.2.1 Purpose 
The purpose of the Environmental Assessment Planning stage is to: 
• 
form the Environmental Change Team who will be involved in the change (and 
will work together throughout further stages of the environmental assessment 
process) 
• 
conduct a risk assessment to identify changes with an unacceptable level of risk 
and assist in determining the level of work that needs to be undertaken in 
environmental analysis and environmental risk mitigation 
• 
plan the remaining assessment activity 
Refer to Figure 1 for a flow diagram of the Environmental Assessment and Planning 
process. 
5.1.2.2 Assessment 
Basis 
The Change Manager (or delegate) shall contact Environmental Services branch and 
Community Relations branch to identify representatives to be part of the Environmental 
Change Team which as a minimum shall be comprised of: 
• 
The Change Manager 
• 
Representatives from Environmental Services and  
• 
Representatives from Community Relations. 
The team may also involve other Subject Matter Experts as necessary. 
On formation of the environmental change team, the Proposal, required assessment 
and community engagement will be discussed and planned (including defining and 
assigning key roles, scheduling progress meetings, and setting milestones and 
deliverable dates). Regular meetings should be conducted throughout the Assessment 
to track progress against milestones. 
As part of planning, a draft risk assessment shall be conducted by the team to 
determine if the change constitutes a ‘Class A’ risk which cannot be mitigated and to 
assess the amount of risk mitigation work required for other risks. 
by Airservices Australia pursuant to the Freedom of Information Act 1982 (Cth)
The risk assessment will consider the following key areas: 
• Community 
Noise 
Impact 
• Aircraft 
Emissions 
Released 
• 
Other environmental impacts (including impacts to wildlife species/communities 
and habitats, and social and heritage considerations).

The risk assessment will be based on high level considerations of known risk factors 
only (e.g. sensitivities described in existing Airport Noise Risk Assessments, fuel use 
thresholds, listed endangered habitats overflown, etc) and will be undertaken in 
accordance with the Environmental Risk Management Standard. Only limited (non 
technical) risk analysis is undertaken at this stage with no detailed environmental 
analysis being undertaken. 
Changes deemed to constitute a Class A risk which cannot be mitigated shall not 
proceed5 and will be diverted from the Assessment process for reconsideration of 
scope. The planned level of environmental analysis and environmental risk mitigation 
should take in to account the risk level of the change. 
Prior to proceeding to further stages of the Assessment, the draft environmental risk 
assessment should be reviewed by the Accountable ATC Manager (or delegate). Risk 
acceptance does not occur at this phase of the Assessment. 
5.1.2.3 Required 
Actions 
The Change Manager (or delegate) shall: 
• 
contact Environment Services Branch6 and Community Relations Branch to 
establish the Environmental Change Team 
• 
clarify the relevant proposal change details (where known), including proposed 
flight path, estimated flight numbers, deadline for implementation of proposed 
change etc7 
• 
not proceed with proposals deemed to have a Class ‘A’ Risk which cannot be 
mitigated (unless the change is redesigned and reassessed or authorised by the 
CEO) 
• 
facilitate review of the draft environmental risk assessment by the Accountable 
ATC Manager 
• 
ensure the Accountable ATC Manager’s comments are captured within the draft 
environmental risk assessment. 
The Environmental Change Team shall: 
• 
agree the composition of the environmental change team  
• 
agree the assessment process (including key roles, progress meeting schedule, 
milestones and deliverable dates) 
• 
throughout the entire process, adhere to the change schedule and defined 
milestones and advise other parties in the environmental change team well in 
advance if delays to agreed deliverables are likely 
• 
throughout the entire process, attend planning meetings and participate in the 
risk assessment process 
• 
agree risk assessment findings.

5.2 
EPBC assessment and referral process 
Under the EPBC Act, actions that have, or are likely to have, a significant impact on a 
matter of National Environmental Significance (NES) require approval from the 
Australian Government Minister for the Environment (the Environment Minister). 
In addition to the above, Section 160 of the EPBC Act, requires Commonwealth 
by Airservices Australia pursuant to the Freedom of Information Act 1982 (Cth)
agencies (such as Airservices) to seek the Environment Minister's advice8  for the 
adoption or implementation of a plan for aviation airspace management involving 
aircraft operations that have, will have, or are likely to have a significant impact on the 
environment in general (i.e. not just impacts to matters of NES).

5.2.1 
Internal EPBC assessment for potential significance 
5.2.1.1 Purpose 
This assessment stage determines whether the change has the potential to cause 
significant impact to the environment, and if it therefore warrants advice from the 
Environment Minister through a referral process in accordance with the EPBC Act. 
5.2.1.2 
Basis of the assessment 
The internal EPBC impact assessment will be undertaken by the Environmental 
Services Branch who will assess the change based on defined assessment criteria.  
For all changes, the internal EPBC assessment criteria for potential significance shall 
be endorsed by the EGM Environment prior to commencement of the assessment. 
Airservices internal EPBC assessment criteria shall: 
• 
define standardised significant impact measures and thresholds which, if 
reached, result in a finding of ‘potentially significant’9. Use of standardised 
measures and thresholds shall minimise the potential for subjectivity within the 
EPBC assessment process; 
• 
considers noise impacts on communities as well as impacts to a range of 
environmental values and is aligned with the ‘Actions on, or impacting upon, 
Commonwealth land, and actions by Commonwealth Agencies, Significant 
Impact Guideline 1.2’ (Commonwealth of Australia 2010). 
A Proposal must be redesigned, or referred for assessment under the EPBC Act, any 
change assessed as having ‘potential significant impact’. 
5.2.1.3 Required 
Actions 
The Change Manager (or delegate) shall: 
• 
Provide all relevant Proposal details (including flight paths, flight frequencies, 
flight numbers, aircraft types etc), required to make the assessment, in 
accordance with agreed project timelines 
• 
accept that when a decision of ‘potential significant impact’ is reached, then the 
Proposal cannot proceed as planned without being referred to the Environment 
Minister 
• 
in consultation with the Accountable ATC Manager, make a decision on whether 
to proceed with the Proposal as planned, or whether to redesign and reassess 
the Proposal (based on the Assessment findings).

9 Note that the assessment should rarely result in a finding of ‘significant impact’ as it is Airservices position that this is a 
determination that only the Federal Environment Minister can make through advice sought by Airservices and following 
formal assessment under the EPBC Act. Further, the reversible nature of Aircraft operations is not consistent with the 
notion of ‘significant impact’.

◦ 
Continuation of the Environmental Business Risk Assessment and 
Management stages (informed by the EPBC Assessment result). 
• 
If the Proposal is deemed ‘potentially significant’ by Airservices: 
◦ 
A decision from the Change Manager (in consultation with the Accountable 
ATC Manager) on whether to proceed with the Proposal as planned (i.e. 
whether to submit a referral under the EPBC Act) 
◦ 
Progression to the EPBC Referral and Assessment stage if the Proponent 
decides to proceed with the Proposal as planned. 
5.2.2 
EPBC referral and assessment under the EPBC Act 
5.2.2.1 Purpose 
The purpose of this stage is to seek advice (through a referral) from the Minister 
regarding whether a Proposal constitutes ‘significant impact’ under the EPBC Act, and 
if so, to have the Proposal formally assessed. 
This is required for all Proposals which have met the criteria for ‘potential significant 
impact’ under the Assessment, and where the Proponent has decided to proceed with 
the Proposal as planned. 
by Airservices Australia pursuant to the Freedom of Information Act 1982 (Cth)
5 2.2.2 Assessment 
basis 
Proposals determined to have ‘potential significant impact’ are ‘referred’ to the 
Environment Minister for advice as to whether the Proposal warrants formal 
assessment under the EPBC Act. This is known as an ‘EPBC Referral’.  
Released 
EPBC Referrals must describe the Proposal (including Proposal details, existing 
environment and potential impacts) and are required to be submitted in the approved 
form (a template is provided on the Department of Environment website). The

Environmental Impact Assessment Process for Changes to Aircraft Operations 
Environment Minister must assess the referral and provide advice within 20 business 
days. 
Following assessment of a referral, the Minister can make one of three decisions as 
follows: 
• 
Controlled action – Action is subject to the assessment and approval 
process
 under the EPBC Act, as the Proposal is deemed likely to cause 
significant impact 
• 
Not controlled action (‘particular manner’) - approval is not required if the 
action is taken in accordance with the manner specified 
• 
Not controlled action – Approval is not required if the action is taken in 
accordance with the Referral. 
If the Minister decides that the Proposal is likely to result in ‘significant impact’ to the 
Environment (i.e. it constitutes a ‘controlled action’) then formal assessment under the 
EPBC Act is required. Formal assessment may be undertaken under a range of 
processes defined in the EPBC Act (as directed by the Minister) which are not 
described in this document. 
5.2.2.3 Required 
Actions 
The Environmental Change Team shall: 
• 
attend regular Proposal meetings and Proposal definition activities as required 
(including workshops and meetings with external government departments) 
• 
review all required information, draft reports and correspondence, and provide 
any required feedback in accordance with agreed project timelines. 
The Change Manager (or delegate) shall: 
• 
provide all relevant Proposal details (including flight paths, flight frequencies, 
flight numbers, aircraft types etc), required to prepare required assessment 
documentation, in a timely manner on behalf of the Proponent. 
Environmental Services shall: 
• 
prepare, or manage preparation of, an EPBC Referral on behalf of the Change 
Manager 
• 
prepare, or manage preparation of, any environmental analysis documentation 
required to support formal assessment under the EPBC Act (if required) 
•

Environmental Business Risk Assessment and Management 
These Assessment stages provide for identification, assessment and management of 
environmental business risks to Airservices resulting from implementation of a 
Proposal. Environmental business risks are those that may not trigger Airservices 
EPBC Assessment criteria, but may still represent environmental, financial and 
reputational business risks for Airservices.  
The Environmental Business Risk Assessment provides an additional tier of impact 
assessment, which complementary to regulatory requirements and further 
demonstrates due diligence in environmental management.  
These Assessment stages incorporate environmental analysis of noise impacts, risk 
analysis, and development of a Community Engagement Plan.   
Key steps in this Assessment stage are further outlined below. While activities are 
identified in a staged order, they are necessarily inter-related and iterative in nature.

5.2.4 
Community Engagement Planning 
5.2.4.1 Purpose 
The purpose of this stage is to: 
• 
inform the level of, and guide the approach to, further environmental impact 
analyses and change design 
• 
commence development of the Community Engagement Plan (CEP) which is a 
significant mitigator for community noise impact. 
5.2.4.2 
Content and approach 
Community Engagement Planning will commence following the definition of change 
environmental risks (following the draft Environmental Risk Assessment, described in 
Section 5.1). It is an iterative process that will continue through subsequent stages of 
environmental analysis and risk assessment. Although drafting may commence, the 
CEP will only be finalised on completion of all Stages of the Environmental Business 
Risk Assessment (and prior to change implementation).  
The CEP guides engagement and consultation with the community in line with 
Airservices Communication and Consultation Protocol.  The CEP will also document 
the process for the Post Implementation Review (PIR) of the environmental impact of 
the change. 
Following the initial Environmental Risk Assessment, and based on the identified risk 
levels, the level of required community engagement and consultation will be 
determined. For example, more in depth community engagement will be necessary for 
identified community noise impacts with a class B risk, than for those with a Class C or 
D risk. 
The required environmental analyses to support this community engagement will also 
be based upon the necessary level of community engagement. For example, more 
detailed noise impact analyses will be recommended for identified community noise 
impacts with a class B risk, than for those with a class C or D.  
The recommended level of community engagement, and environmental analyses to 
support the planning, will be discussed and agreed with the Environmental Change 
Team, prior to Community Relations and Environmental Services developing the 
associated plans and conducting the analyses. 
5.2.4.3 Required 
Actions 
The Environment Change Team shall: 
• 
agree the recommendations of the Community Engagement Planning stage. 
The Change Manager (or delegate): 
by Airservices Australia pursuant to the Freedom of Information Act 1982 (Cth)
• 
Review and provide comment on the draft and final version of the CEP; 
• 
Accept the recommendations of the Communication and Engagement Planning 
stage.

Community Relations shall: 
• 
manage the community engagement planning phase 
• 
recommend the level of Community Noise Impact Analysis to be undertaken to 
support preparation of the CEP 
• 
ensure appropriate involvement (and where necessary signoff) from subject 
matter experts (including Government and Industry Affairs) and alignment with 
other stakeholder engagement plans. 
5.2.4.4 Outcomes 
• 
Commencement of drafting of the CEP 
• 
A defined focus and level of Community Noise Impact Analyses to be undertaken 
to support preparation of the CEP 
• 
An agreed level and focus of community engagement and consultation (as 
documented in the CEP). 
5.2.5 
Environmental Analysis  
5.2.5.1 Purpose 
The purpose of this stage is to identify and analyse potential environmental, financial 
and reputational business impacts and benefits of the change.   
5.2.5.2 
Assessment Basis  
The Environmental Analysis stage provides additional information about the proposed 
change with respect to the three key areas of potential environmental impacts (and 
benefit) as follows: 
• Community 
Noise 
Impact 
• Emissions 
• 
Other environmental issues (including impacts to wildlife species/communities 
and habitats, and social and heritage considerations). 
There must be an agreement within the Environmental Change Team on the purpose 
for conducting individual analyses. These may include: 
• 
to support refinement or optimisation of the design (including alignment with, and 
incorporation of EBD principles wherever possible) 
• 
to support community engagement and consultation planning  
• 
to define potential noise or emissions benefits 
• 
to support an EPBC Referral (after a potential need for referral has been 
identified through the EPBC Assessment Process ) 
• 
to assist in communication or engagement with other stakeholders (e.g. Industry) 
by Airservices Australia pursuant to the Freedom of Information Act 1982 (Cth)
Environmental Services will lead the analyses where appropriate but will work closely 
with the Environmental Change Team throughout the process. 
The level and focus of analyses will be determined by the drivers for conducting the 
Released 
analysis.  For example, electoral boundary analysis may be conducted to support 
stakeholder engagement planning where risks associated with particular demographics 
or interest groups have been identified.

5.2.6.2 Process 
description 
Risk review and acceptance 
Following environmental analysis and communication planning, the environmental 
business risks are updated (by Environmental Services Branch) and need to be 
reviewed and accepted (or rejected) by the Accountable ATC Manager (or delegate). 
Risk review at this stage will also consider any Ministerial advice or assessment 
findings following any EPBC Referral or assessment processes undertaken in 
accordance with the EPBC Act (as described in Section 5.2.2).  
Upon risk acceptance, the proposal can proceed to the CEP implementation stage.  If 
the risk is not accepted the proposal must be redesigned or not pursued further. Risk 
acceptance recorded in CIRRIS  
Following implementation of the CEP, a further risk review and update is undertaken 
based on the findings of the community engagement and consultation process.  This 
process captures the feedback received from the community and ensures that the risk 
assessment reflects this information. On acceptance of the resulting risk, the Proposal 
can be implemented (if not accepted it must be redesigned). 
CEP Implementation  
The CEP is implemented in accordance with the methodology it describes. 
Implementation methodology will vary for each CEP (targeted to the particular 
Proposal) but is likely to include: 
• 
a presentation to relevant community groups and bodies (e.g. Airport Community 
Aviation Consultation Groups – CACGs) where the proposed change is 
communicated, (including timeframes for implementation, flight paths, and likely 
noise levels/associated impacts) 
• 
publication on the Airservices website 
• 
participation in other activities required by other stakeholder engagement plans 
(e.g. Communication to politicians) where necessary 
• 
a request for comments on the intended Proposal to be provided by a specified 
date. 
5.2.6.3 Required 
Actions 
The Environment Change Team shall: 
• 
agree the updated risk level (pre and post CEP implementation) 
• 
collaborate to implement the CEP as required 
• 
discuss outcomes of the CEP implementation (and consultation process) and 
agree any required changes to risk assessments and/or Change design 
by Airservices Australia pursuant to the Freedom of Information Act 1982 (Cth)
• 
agree any further environmental actions that must undertaken taken as follows: 
◦ 
prior to implementation of the Proposal (if final risk accepted) 
◦ 
with respect to redesign or re-assessment (if final risk is not accepted)

Explanatory notes: 
1.  A change is any Airservices initiated variation to air traffic management 
practices that may involve a change to aircraft operations. Changes include, but 
are not limited to: 
  A new, or amendment to an existing, instrument approach 
  A new, or amendment to an existing, flight path or air route 
  Re-classification of airspace 
  Change to preferred runways 
  Change in time of day of operation (e.g. amendments to tower hours of 
operation – the time of day that a tower operates may alter the flight 
path used by aircraft) 
  A change that allows use of a flight path/airspace by a different type or 
number of aircraft. 
2.  A tactical decision of an air traffic controller to alter the track of an individual 
aircraft does not constitute a Proposal. 
3.  Residential areas are identified through analysis of aerial photographs and/or 
satellite imagery. 
4.  Screening criteria are designed to fast-track proposals with impacts far below 
the thresholds for significance applied to full assessments. 
5.  After a proposal is self-assessed as “not requiring further environmental 
assessment”, the findings are reviewed by the Environmental Services Branch. 
6.  Screening criteria may only be applied by proponents who have undergone 
appropriate training in the use of, and basis for, the criteria. 
7.  Average traffic levels may be applicable at locations where there is little 
variation in movements throughout the year unless specifically excluded in the 
table above. Also specifically excluded are those locations that host special 
events attracting additional movements such as air shows.
