Solicit input from agencies and the public •
Identify significant environmental issues to be analyzed • in greater depth
Eliminate from detailed study issues that are insignificant • or have been covered by prior environmental review
Set temporal and geographic boundaries for impact analysis•
Identify available technical information and additional • reasonable alternatives, if any
Identify necessary permits, licenses, approvals, authorizations •
Clarify areas of special expertise•

Runway Safety Area (RSA) EnhancementsRunway 1-19
In order to comply with Federal Aviation Administration (FAA) Order 5200.8 and FAA Advisory Circular 150/5300-13, the Authority is examining the configuration of the Runway 1-19 Runway Safety Area (RSA) at Ronald Reagan Washington National Airport.
The proposed enhancements to the Runway 1-19 RSA will bring the RSA into compliance by the 2015 FAA deadline.
Preliminary Purpose & Need
Runway Safety Area Enhancements
Ronald Reagan Washington National Airport
PUBLIC INFORMATION WORKSHOP ENVIRONMENTAL ASSESSMENT SCOPING JULY 30, 2008
Runway Safety Area (RSA) EnhancementsRunway 1-19
Definition: A defined surface surrounding the runway intended to provide a measure of safety in the event of an aircraft’s excursion from the runway by significantly reducing the extent of personal injury and aircraft damage during overruns, undershoots, and veer-offs.
Standard RSA Dimensions for Aircraft Using DCA 500 feet wide•
600 feet prior to the landing threshold•
1,000 feet beyond the runway end •
Compliance Deadline is 2015 (2006 Transportation Appropriations Act)•
Congress and Department of Transportation (DOT) Office of Inspector General • continually monitor FAA and airport progress

DNL = Day-Night Average Sound Level - A metric used todescribe the existing and predicted cumulative noise exposurefor communities surrounding the Airport. DNL is expressed inA-weighted decibels (dBA) and represents the average noiselevel over a 24-hour period. In calculating DNL, the averagesound level for each hour during the nighttime period(10:00 p.m. to 7:00 a.m.) is increased by a 10-decibel weightingpenalty.
