4 Environmental Study Process What is Environmental Filtering?Low level data assessment of a potential for environmental impactFocuses on information and data collectionWhat is Environmental Prescreening?Low level data assessment in the risk for a potential environmental impactFocuses on data assessment and various low level tests based on operational, procedural, and lateral changesWhat is Environmental Screening?Low fidelity data modeling which must be constructed with low risk of false-negative resultsDramatic simplification of the of a detailed noise analysisWhat is Environmental Analysis?High fidelity data modeling used to determine the potential environmental impacts for multiple scenariosDetailed noise/environmental impact evaluation
6 Environmental Study Process Goals Consistent and streamlined process for investigating environmental impactsFollow National Environmental Policy Act (NEPA) requirementsCapture key environmental issues early to prepare schedules and budgets accordinglyDetermine if procedure request can be CATEXed early in assessment processExercise very low risk of false-negative impact resultsE.g. Actions which exceed noise change thresholds deemed as no/low level of impact

9 Environmental Filtering - Overview Environmental PrescreeningEnvironmental ScreeningEnvironmental AnalysisTool: Environmental Screening FilterThe Environmental Screening Filter provides a standard streamlined audit process for stepping through the logic of the environmental process for a proposed procedure change.Purpose:The purpose of environmental filtering is to collect enough environmental information for the application of a categorical exclusion for a requested procedure approval.Expected Time Investment: MinimalPossible Outcomes:CATEXEnvironmental Prescreening (further review)
10 Environmental Filtering – Information Gathering Environmental PrescreeningEnvironmental ScreeningEnvironmental AnalysisThe environmental filtering process requires the following information to be collected in order to properly assess the impact of a proposed action:Involves an Instrument Flight Procedure (IFP) service provider?Involves new or an existing Procedure?Involves procedure change(s) covered under 311k or 311i?Involves change(s) over major thoroughfare?Average daily helicopter operation countInvolves change(s) over noise sensitive areas?E.g. park, wilderness, residential, educational, etc.Involves a procedure update?E.g. name change, increase in altitude, lines of minimumLowest altitude in procedure requestAverage annual prop and jet operation counts
12 Environmental Prescreening - Overview Environmental FilteringEnvironmental PrescreeningEnvironmental ScreeningEnvironmental AnalysisTool: NST – Prescreening Guidance WizardProvides a standard streamlined audit process for determining if a proposed action poses a risk of exceeding a noise threshold.Requires acquisition of a minimal amount of data to analyze small degrees of changeDetermines if noise screening is needed through a series of questions and look up tablesSupporting Documentation:MITRE – Guidance for Noise Screening Air ActionsExpected Time Investment:MinimalPossible Outcomes:CATEXEnvironmental Screening (further review)NST Prescreening Guidance Wizard
14 Prescreening – Lateral Test Environmental FilteringEnvironmental PrescreeningEnvironmental ScreeningEnvironmental AnalysisRequired Information:Change in Lateral DistanceMinimum Aircraft Procedure AltitudePurpose:Does the action move jet traffic far enough to potentially exceed a screening threshold? This test is only for actions where a route is moving laterally and there are no changes in the number of jet traffic operations or altitudes along the route?
15 Prescreening – Altitude / Operations Test Environmental FilteringEnvironmental PrescreeningEnvironmental ScreeningEnvironmental AnalysisRequired Information:Change in Daily Jet Traffic OperationsChange in Minimum Altitude of Jet TrafficPurpose:Does the action change the altitudes and/or amount of jet traffic on an existing route enough to potentially cause a 3 dB increase in noise exposure?

20 Environmental Analysis - Overview Environmental FilteringEnvironmental PrescreeningEnvironmental ScreeningEnvironmental AnalysisWhat is Environmental Analysis?High fidelity data modeling process used to determine the potential environmental impacts for multiple scenariosEnvironmental analysis is the final stage of evaluation process for a proposed procedure request.When a proposed request cannot be CATEXed in any of the previous steps and has the potential risk of an environmental impact, a detailed analysis is requiredAfter the in depth analysis is complete, a record of decision is prepared stating the final decision of the review and identifies all alternatives considered in the decisionTools:Aviation Environmental Design Tool (AEDT)Integrated Noise Model (INM)Emissions and Dispersion Modeling System (EDMS)Legacy Tools:Noise Integrated Route System (NIRS)Expected Time Investment: SignificantPossible Outcome:EA / EISAviation Environmental Design Tool (AEDT)
21 Aircraft Procedure Request Environmental Process The result will be one of two outcomes: identification of a possible CATEX or the need for additional environmental review. In both cases, the filter will create a summary of the proponent information entered. When the filter identifies a CATEX, it will also produce an unofficial CATEX Declaration.
22 Aircraft Procedure Environmental Pre-screening Filter After entering information concerning a proposed procedure into the filter, proponents will know whether a CATEX is identified and implemented, or whether further environmental review will be required.

24 Aircraft Procedure Environmental Pre-screening Filter The filter outputs will be ed to the FAA for review. The FAA will determine whether the filter information is complete and complies with FAA Order E paragraph 303C. If the filter information is not complete, it will be returned to the proponent for review.Perform Additional Environmental ReviewComplete/ Update Procedure Action DesignPublish or Implement ProcedureComplete Environmental Pre-screening FilterReview Environmental SubmissionDevelop ProcedureNeed for New/Updated Aircraft ProcedureYESNOPassed Environmental Review?No Changes or Changes within Environmental Parameters?New/Updated Procedure Published or ImplementedReceive FAA Responsible Federal Official (RFO) Approval
25 Review of the Filter Results After the filter identifies a CATEX or the need for additional environmental review, the results will be sent via to the FAA specialist coordinating the proposed procedure for review. The will include the following attachments:A PDF of the questions and responses entered into the Filter by the proponent, and eitheran unofficial CATEX Declaration, orinstructions for additional environmental review,Electronic satellite (such as Google) or land use map (if the proposed procedure directs traffic over a noise-sensitive area)

27 Operations Support Group (OSG) Flight Procedures Team (FPT) The OSG FPT will review the filter results, verify information and ensure the results comply with FAA Order E paragraph 303C. The expected outcomes are to:Produce an approved CATEX declaration to be included in the procedure packageSend a completed procedure package to AeroNav Products for development if the conditions for a CATEX are met, orForward the procedure package to the OSG Environmental Specialist (ES) if a CATEX can not be appliedReturn the filter results to the proponent to determine next steps if information submitted is incomplete
28 OSG Environmental Specialists An OSG ES will use the filter results to verify whether the proposed procedure meets the conditions for:A CATEX declaration,An environmental assessment (EA), orAn environmental impact statement (EIS).The OSG ES will send the results of the additional environmental review to OSG FPT for final processing.
29 OSG Environmental Specialists If the filter results indicate that additional environmental review is required, an OSG ES will conduct the review using the filter results as a starting point to determine the appropriate level of environmental documentation required for the action:CATEX,Environmental assessment (EA), orEnvironmental impact statement (EIS).
30 OSG Environmental Specialists Third Party Special IFPsAn OSG ES will also review filter results for AFS third party IFP submittalsThird party applications will be processed the same as othersIf further environmental review is required the OSG ES will conduct the reviewIf further information is required to complete the environmental review the OSG ES will send the information request back to AFS to work with the applicantThe OSG environmental specialist will send the results of the additional environmental review to AFS for final processing
32 OverviewHowever, the filter will never be used as a substitute for human expertise in the review process. In fact, human expertise will be essential in reviewing the output(s) of the filter. The FAA personnel who have been responsible for environmental review in the past will retain their roles as reviewers.
