8 8 Federal Aviation Administration Environmental Study Process Overview June 26, 2013 Step 1 Environmental Filtering

9 9 Federal Aviation Administration Environmental Study Process Overview June 26, 2013 Tool: Environmental Screening Filter –The 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: Minimal Possible Outcomes: –CATEX –Environmental Prescreening (further review) Environmental Filtering - Overview

10 10 Federal Aviation Administration Environmental Study Process Overview June 26, 2013 Environmental Filtering – Information Gathering The 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 count –Involves 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 minimum –Lowest altitude in procedure request –Average annual prop and jet operation counts

20 20 Federal Aviation Administration Environmental Study Process Overview June 26, 2013 What is Environmental Analysis? –High fidelity data modeling process used to determine the potential environmental impacts for multiple scenarios –Environmental 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 required –After 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 decision Tools : –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: Significant Possible Outcome: –EA / EIS Aviation Environmental Design Tool (AEDT) Environmental Analysis - Overview

21 21 Federal Aviation Administration Environmental Study Process Overview June 26, 2013 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. Aircraft Procedure Request Environmental Process

22 22 Federal Aviation Administration Environmental Study Process Overview June 26, 2013 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.
