Section 3 - Site Description
This section describes facility activities and the airport setting. The MSGP-2010 (Part
5.1.2.3) also requires the SWPPP to identify the nearest receiving water(s) that may
receive discharges from the facility.
3.1 Facility Activities
This section describes industrial activities conducted at PHX as required by MSGP-2010
Part 5.1.2.
PHX is primarily a commercial service airport. There are some private GA tenants and
commercial FBOs providing storage and aircraft maintenance services. PHX is also the
location of the 161st Air Refueling Wing of the Arizona Air National Guard. The airport
was built in 1928 and has been operated by the City of Phoenix since 1935. PHX has
undergone several expansions since 1935. In 2012, PHX averaged approximately 1,200
flight operations daily on three existing runways.
Approximately 75 percent of the PHX facility is covered by impervious surfaces such as
buildings, runways, taxiways and parking lots. The pervious surfaces comprising the
remainder of the PHX facility are concentrated in the southern portion of the airport,
along the Salt River. Land use in the surrounding area consists of predominantly
industrial and commercial property.
Industrial activities at this facility include:
• Aircraft, Ground Vehicle and Equipment Maintenance
• Aircraft, Ground Vehicle and Equipment Cleaning
• Aircraft, Ground Vehicle and Equipment Storage
• Material Storage Areas
• Airport Fuel System and Fueling Areas
• Building and Grounds Maintenance
• Aircraft Deicing
3.2 General Location
PHX is located in south central Arizona, approximately two miles east of the central
business district of the City of Phoenix. The airport is situated north of the Salt River and
encompasses approximately 2,450 acres. Figure 1 is the General Location Map for PHX.
The map shows the location of the facility and the receiving waters within one mile of
the facility (MSGP-2010 Part 5.1.2.3).
Stormwater at PHX drains through a series of storm sewers to 18 outfalls to the Salt
River. Some of the storm sewers are continuations of the City of Phoenix municipal
