The U.S. DOT pprpriatins ct fr FFY 2006 requires the peratrs f all airprts certificated under 14 CFR Part 139 t cmply with F regulatry requirements fr s by FFY The ct als requires the F t reprt annually n its prgress tward achieving cmpliance. F C 150/ prvides dimensinal requirements fr s based n the physical and perating characteristics f the design aircraft perating at an airprt. Based n the characteristics f aircraft perating n Runway 1-19 at the irprt, the current standard dimensins are: 500 feet wide and centered n the centerline f the runway; 1,000 feet beynd the departure runway end; and 600 feet prir t the landing threshld. Prir t September 30, 2004, the standard dimensins prir t the end f the runway and beynd the end f the runway fr the type f aircraft perating n Runway 1-19 were the same: 1,000 feet. F C 150/ , Change 8, reduced the dimensin prir t the landing threshld frm 1,000 feet t 600 feet. Exhibit II-3 depicts the standard verlaid nt existing Runway 1-19, illustrating the shift in dimensins at the runway ends depending n the directin in which the aircraft perates. Fr example, when aircraft arrive n and depart frm Runway 1 (i.e., perate in a nrth flw), the dimensinal requirements fr the wuld be 600 feet prir t the Runway 1 threshld and 1,000 feet beynd the end f the runway (i.e., the nrth end f the runway). Cnversely, in suth flw cnditins with arrivals n and departures frm the Runway 19 end, the dimensinal requirements fr an wuld be 600 feet prir t the Runway 19 threshld and 1,000 feet beynd the end f the runway (i.e., the suth end f the runway). Within the, the F requires surface cnditins t be: Cleared, graded, and withut ptentially hazardus ruts, humps, depressins, r ther surface variatins; Drained by grading r strm sewers t prevent water accumulatin; Capable, under dry cnditins, f supprting snw remval equipment, aircraft rescue and fire fighting equipment, and the ccasinal passage f an aircraft withut causing structural damage t the aircraft; and Free f bjects, except fr bjects that need t be lcated in the because f their functin. 5 Federal viatin dministratin Order , Financial Feasibility and Equivalency f Runway Safety rea Imprvements and Engineered Material rresting Systems, Sectin 1.

The existing nnstandard is shwn n Exhibit II Runway 1 Hld prn Functin and Design Standards ircraft departures frm airprts can be affected by weather, airspace, and perating cnditins at the destinatin airprts. On ccasin, infrmatin n the cnditins at the destinatin airprts may becme available t a flight crew nly after an aircraft leaves a terminal gate r remte parking aprn and the aircraft is taxiing t the runway fr its anticipated scheduled departure. Departure hld aprns are intended t: prvide a standing space fr aircraft awaiting final air traffic cntrl (TC) clearance t take ff, permit thse aircraft cleared fr take-ff t mve t their runway take-ff psitins, and enhance maneuverability fr hlding aircraft while als permitting bypass peratins. The mst advantageus psitin fr a hld aprn is adjacent t the taxiway serving the runway end 7 t avid cngestin in the terminal area and t reduce taxiing times t the runway end when the aircraft receives clearance fr takeff. Develping and maintaining the apprpriate number f runway hld aprns f the apprpriate sizes at an airprt are essential t maintaining airprt departures at a level that reflects the TCT departure rate. F C 150/ establishes the grading and gemetry design standards fr hld aprns and the taxilanes and taxiways assciated with hld aprns. The dimensinal design standards vary accrding t the number and size f aircraft that perate at an airprt and the anticipated number f such aircraft that may need t be held at any ne time n the hld aprn prir t take-ff Existing Cnditins Depending n the size f aircraft, the Runway 1 Hld prn can accmmdate up t three aircraft. In cnsultatin with TCT staff, it was determined that the Runway 1 Hld prn has insufficient capacity. The size f the aircraft perating at the irprt has increased ver the years, and the size f the Runway 1 Hld prn des nt prvide sufficient clearance fr the largest aircraft t bypass the hld aprn t mve t its Runway 1 take-ff psitin. Therefre, the functin f the Runway 1 Hld prn is limited t the queuing f aircraft awaiting departure. irfield cngestin is cmmn during summer thunderstrms.

15 Rnald Reagan Washingtn Natinal irprt deterirating depends n several factrs, including cnstructin type and quality, pavement use, climate, and maintenance. The uthrity uses a Pavement Management System at the irprt t evaluate the present cnditin f the pavement, and als t predict its future cnditin thrugh the use f a pavement cnditin indicatr. By prjecting the rate f deteriratin, the uthrity can analyze life-cycle csts fr varius alternatives. This analysis helps t determine the ptimal time fr pavement imprvements. 8 The Runway 1-19 pavement was last verlaid in 1990 and, at that time, the uthrity predicted that anther verlay wuld be needed in apprximately 12 years. It has been 18 years since the last verlay and the cnditin f the runway surface has deterirated t the pint that an verlay will be needed within the next several years. 2.2 Purpse and Need Statement The Prblem (Need) The F has determined that the Runway 19 extends beynd the nrthern end f Runway 19 by 750 feet, which falls shrt f the 1,000-ft F design standard. 9 s the peratr f the irprt, a federally bligated airprt certificated under 14 CFR Part 139, the uthrity is bligated by F Order and the U.S. DOT pprpriatins ct fr FFY 2006 t cmply with F regulatry requirements fr s by The size f the current Runway 1 Hld prn des nt prvide fr the largest aircraft perating at the irprt t bypass aircraft n the hld aprn, thereby limiting the functin f the hld aprn t the queuing f aircraft awaiting departure. Further, as nted in Sectin 2.3, the uthrity s prpsed slutin t the Runway 1-19 cmpliance issue wuld require using a prtin f the Runway 1 Hld prn fr the extensin f Taxiway J. Insufficient Runway 1 Hld prn capacity exacerbates delays at the irprt and thrughut the Natinal irspace System. The uthrity s Pavement Management System and inspectins f the cnditin f the surface f Runway 1-19 pavement indicated that an verlay will be needed within the next several years The uthrity s Slutin (Purpse) F Order identifies the alternatives that must be analyzed when an des nt cmply with applicable F C 150/ standards. 10 Thse alternatives are t: Cnstruct a standard ; Relcate, shift, and/r realign the runway; Reduce the length f the runway; Implement a cmbinatin f relcating, shifting, and/r realigning the runway and reducing runway length; Use declared distances; r Federal viatin dministratin, dvisry Circular 150/5380-7, irprt Pavement Management Prgram, 3.0 a.

16 Rnald Reagan Washingtn Natinal irprt Use Engineered Material rresting Systems. The critical design aircraft fr Runway 1-19 is identified n the LP as the Being t a standard day temperature f 59 degrees Fahrenheit and an elevatin at sea level, 12 the Being 757 requires a runway length between 6,500 and 9,900 feet at its maximum take-ff weight, depending n the engine and mdel type. 13 The uthrity believes that it is imprtant t maintain the existing length f Runway 1-19 at 6,869 feet. Declared distances are the distances an airprt wner declares available fr an aircraft s take-ff run, take-ff distance, accelerate-stp distance, and landing distance requirements. 14 EMS uses materials f clsely cntrlled strength and density placed at the end f a runway t stp r greatly slw an aircraft that verruns the runway. The best material fund t date is a lightweight, crushable cncrete. When an aircraft rlls int an EMS arrestr bed, the tires f the aircraft sink int the lightweight cncrete and the aircraft is decelerated by having t rll thrugh the material. 15 F C 150/ establishes the design criteria fr s and hld aprns. Within the cntext f the requirements f F Order and F C 150/ , the uthrity has cnducted a number f studies addressing enhancements t the Runway 1-19 and the Runway 1 Hld prn.

The uthrity s Pavement Management System and inspectins f the cnditin f the surface f Runway 1-19 pavement indicated that an verlay will be needed within the next several years. Cnstructing a standard wuld enable the uthrity t bring the Runway 1-19 int cmpliance with F Order and F C 150/ Expansin f the Runway 1 Hld prn wuld allw the largest aircraft perating at the irprt t bypass ther aircraft n the hld aprn. Resurfacing Runway 1-19 wuld extend the useful life f the Runway 1-19 pavement. 2.3 Prpsed ctin The uthrity s Prpsed ctin includes the key elements described belw. Except fr the recnfiguratin f the apprach lights, as described belw, all cnstructin wuld take place n irprt prperty. Extensin f the Runway 1-19 pavement 300 feet t the suth.
