1. PLANNING AND ORGANIZATION 1.1 Introduction
The Ernest A. Love Field/Prescott Municipal Airport (the Airport) is eligible to be covered under the Arizona Department of Environmental Quality (ADEQ) Arizona Pollutant Discharge Elimination System General Permit for Stormwater Discharges Associated with Industrial Activity from Non-Mining Facilities to Waters of the United States (herein referred to as the “General Permit”). The General Permit became effective on February 1, 2011, and expires on January 31, 2016. The General Permit authorizes stormwater discharges associated with ADEQ‐defined industrial activities. Under the General Permit, the Airport is categorized as an “Other Eligible Discharger”. That is, a facility that is in operation prior to the effective date of the General Permit, but did not obtain coverage under the MSGP 2000 or another AZPDES permit. As such, the Airport must develop a Storm Water Pollution Prevention Plan (SWPPP) document to comply with the General Permit and apply for coverage. Coverage will begin upon ADEQ issuance of an Authorization to Discharge. A SWPPP is designed to identify structural and non‐structural controls that will be put in place as means to minimize negative impacts to the environment that may be caused by storm water discharges from the subject property. The SWPPP establishes procedures for minimizing the potential for pollutants to be carried away in storm water discharges. These procedures emphasize the use of Best Management Practices (BMPs) to provide the flexibility to address varying sources of pollutants at different categories of industrial facilities (in this case, a public use airport). Preparation of the Ernest A. Love Field/Prescott Municipal Airport SWPPP was based upon the existing conditions at the airport in September, 2011 with reference to existing available mapping and documents that were provided by the Airport, as well as site investigations and interviews with Airport personnel and tenants. Work was accomplished in accordance with the requirements of FAA Advisory Circular AC 150/5320‐15A, dated September 8, 2008.
1.2 Governing Law In 1972, Congress passed the Clean Water Act (CWA). The CWA seeks to protect and improve the quality of the nation's waters. Toward this end, the Clean Water Act prohibits the discharge of any pollutants to waters of the United States unless that discharge is authorized by a National Pollutant Discharge Elimination System (NPDES) permit. Initial efforts under the NPDES program focused on reducing pollutants in discharges of industrial process wastewater and municipal sewage. As pollution control measures were implemented, it became evident that there were other sources contributing to the degradation of water quality. In 1990, the U.S. Environmental Protection Agency (EPA) published regulations governing storm water discharges under the NPDES program. These regulations established
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)
2
requirements for permitting storm water discharges from industrial facilities, construction sites, and municipal storm sewer systems (not affiliated with the Airport system). In December 2002, EPA delegated the State’s NPDES storm water program to the Arizona Department of Environmental Quality (ADEQ). At that time, the storm water program was renamed the Arizona Pollutant Discharge Elimination System (AZPDES). Polluted storm water runoff is a leading cause of lowered water quality in our State. In response to this problem, the ADEQ established requirements to control storm water discharges that could harm the quality of waterways and washes in Arizona.
1.3 Objectives The objectives of the Ernest A. Love Field/Prescott Municipal Airport SWPPP are as follows: a. Identify potential sources of storm water and non-storm water contamination to the
storm water drainage system; b. Identify and prescribe appropriate "source area control" best management practices
(BMPs) designed to prevent storm water contamination; c. Identify and prescribe "storm water treatment" BMPs to reduce pollutants in
contaminated storm water prior to off-airport discharge (if applicable); d. Prescribe actions needed either to bring non-storm water discharges under applicable
permit or to remove these discharges from the storm drainage system; e. Prescribe an implementation schedule so as to ensure that the storm water
management actions prescribed in the SWPPP are carried out and evaluated on a regular basis.
1.4 Consistency with Other Plans
The SWPPP has been prepared in conformance with the ADEQ General Permit, in accordance with the requirements of FAA Advisory Circular AC 150/5320‐15A, dated September 8, 2008.

3. SITE ASSESSMENT 3.1 General Description of the Airport Site
Ernest A. Love Field/Prescott Municipal Airport is situated on approximately 760 acres of land approximately 7 miles north of the City of Prescott. The Airport is classified by the FAA as a Class II Commercial Service public use airport. The Airport is owned by the City of Prescott, and serves both the commercial and general aviation needs for the City of Prescott, greater Yavapai County and residents of the local Yavapai Reservation. There are approximately 243,000 annual operations (aircraft departures and arrivals) at the Airport, including approximately 3,600 airline operations (with about 5,400 annual passenger enplanements), and about 126,000 training operations. There are currently approximately 345 aircraft based at the Airport. The Airport dispenses approximately 397,000 gallons of 100 Low Lead aviation fuel, and 305,000 gallons of Jet‐A annually. Airfield improvements include three paved and lighted runways, paved taxiways, extensive hangar areas, and commercial development. The Airport’s surveyed elevation is 5,045 feet above Mean Sea Level (MSL). Major businesses located on the Airport property include the following:
Embry‐Riddle Aeronautical University – flight training, charter, aircraft rental
Legend Aviation – Aircraft fueling, FBO services
Northaire – flight training, charter, aircraft rental
Guidance Helicopters – flight training, charter, aircraft rental
Arizona Air Craftsman/Wing Nuts – Aircraft maintenance
Granite Mountain Aviation Services – Aircraft maintenance
Mile High Avionics – Avionics service
Nostalgaire – Aircraft maintenance
Prescott Aircraft – Aircraft maintenance
Rittaire – Aircraft storage hangars and commercial facilities
Arizona Aviation Supplies – Pilot supplies
Monarch Aviation – Aircraft storage hangars
Suzy’s Skyway Restaurant – Restaurant/catering
Hertz – Rental cars The U.S. Forest Service maintains an air tanker firefighting base at the Airport that is operated seasonally from May through July, although some fire seasons dictate opening as early as mid‐April and closing as late as October. Adjacent commercial and industrial uses include the Sturm Ruger firearms plant, and the Yavapai College diesel mechanic training facility, both located northwest of and immediately adjacent to the airport. The Antelope Hills Golf Course equipment and vehicle maintenance facility is located immediately south of the Airport.

The Airport property is drained by a storm drainage system consisting of a network of drainage ditches and subsurface storm sewers. Drainage is generally towards the northeast. Ultimate receiving waterway is Granite Creek, which is classified as an EPA Impaired Water.
3.2 Allowable Non‐Stormwater Discharges
Section 1.1.3 of the ADEQ General Permit identifies the non‐stormwater discharges that are allowed under the current permit. Discharges from emergency fire‐fighting activities are an allowable non‐stormwater discharge activity without regard to the receiving water. Other discharges are allowed provided that they are ancillary to the permitted use (in this case, ancillary to the operation of the Airport). These other allowable uses are as follows: 1. Fire fighting system testing and maintenance, including hydrant flushings; 2. Discharges related to installation and maintenance of potable water supply systems,
including disinfection and flushing activities, discharges resulting from pressure releases or overflows, and discharges from wells approved by ADEQ for drinking water use;
3. Uncontaminated condensate from air conditioners, evaporative coolers, and other compressors and from the outside storage of refrigerated gases or liquids;
4. Irrigation drainage and irrigation line flushing; 5. Landscape watering provided all pesticides, herbicides, and fertilizer have been applied
in accordance with the approved labeling; 6. Pavement wash waters where no detergents are used and no spills or leaks of toxic or
hazardous materials have occurred (unless all spilled material has been removed); 7. Routine external building washdown that does not use detergents; 8. Water used to control dust, provided effluent or other wastewaters are not used; 9. Uncontaminated groundwater or spring water; 10. Foundation or footing drains where flows are not contaminated with process materials
such as solvents; 11. Incidental windblown mist from cooling towers that collects on rooftops or adjacent
portions of the facility, but not intentional discharges from the cooling tower (e.g., “piped” cooling tower blowdown or drains);
12. Hydrostatic testing of new pipes, tanks or vessels using potable water, surface water, or uncontaminated groundwater;
13. Discharges of water associated with drilling, rehabilitation and maintenance of potable or non‐potable water wells and peizometers, or water supply or water quality evaluations including:
a. Discharges from any borehole not fully developed; b. Well purging; c. Well/aquifer pump tests not associated with groundwater remediation activities; d. Backflushing of injection wells provided the discharge meets applicable water quality
standards; and 14. For airports where a single permittee, or a combination of permitted facilities use more
than 100,000 gallons of glycol‐based deicing chemicals and/or 100 tons or more of urea on an average annual basis, the airport must monitor Biochemical Oxygen demand (BOD5), Chemical Oxygen demand (COD), Ammonia, and pH in those outfalls that collect runoff from areas where deicing activities occur.
The ADEQ General Permit does not authorize the discharge of aircraft, ground vehicle, runway and equipment wash waters; or the dry weather discharge of deicing chemicals.
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)

Such discharges must be covered by separate AZPDES permits. (Note that a discharge resulting from snowmelt is not considered to be a dry weather discharge).
3.3 Identification of Potential Pollution Sources
The following have been identified as potential sources of storm water pollution. The noted Map Location Indices refer to Exhibit 3 in the Appendix. Each specific potential source is also depicted on a drawing (Figures A through N) at the end of this section. A Self‐Serve Aviation Fueling Facility (Map Location Index A and Figure A)
This installation is a stand‐alone card reader storage tank and delivery system that has the capacity to store 6,000 gallons of 100 Low Lead Aviation Fuel. Delivery to aircraft is performed by the aircraft operators. The tank is double walled and monitored, but it is not located in a spill containment sump. No spill kits were found at the fueling facility location during the SWPPP site investigations. In the event of a spill, drainage will be to the east over the paved aircraft apron toward the infield subsurface storm drainage system. Potential contaminants: 100‐octane Low‐Lead Aviation Fuel
B Legend Aviation Fuel Farm Installation (Map Location Index B and Figure B) This is the primary fuel storage site for the Airport. The equipment is owned and operated by Legend Aviation on land leased from the Airport. There are a total of four double walled aviation fuel tanks at the site with a total storage capacity of 80,000 gallons. Two tanks store 20,000 gallons each of Jet‐A and two store 20,000 gallons each of 100LL Avgas. The four tanks are located in a concrete containment sump. A 2,000 gallon Airport‐owned double walled split fuel tank is located adjacent to the main tanks, but is not within the containment sump. This tank stores 1,000 gallons of auto gas and 1,000 gallons of diesel fuel. The Airport has plans to relocate this tank in the future to a site adjacent to the administration building in the northwest corner of the airport. The concrete containment sump may be drained by a manually operated valve that drains the sump to the Airport’s surface drainage system. The valve is always in the closed position unless manually opened after a visual inspection to determine if any petroleum sheen is present. If petroleum is present, effluent is pumped and properly disposed of off‐site. Potential contaminants: 100‐octane Low‐Lead Aviation Fuel; Jet‐A Aviation Fuel; Automotive grade gasoline; Diesel fuel

C Aircraft Fueling from Trucks and Carts, and Fuel Truck Storage (Map Location Index C and Figure C) Legend Aviation provides on‐ramp aircraft fueling from three fuel trucks that are filled at the Fuel Farm Installation. These trucks are stored (parked) in an open concrete containment area within Legend’s lease holding area. The containment parking area can accommodate five trucks. After a storm event, the containment sump is inspected by Legend Aviation personnel and then drained by pumper trucks through a manually‐actuated valve and pumper connection. Trucks are available to fuel aircraft on any of the Airport’s parking aprons and hangar areas, as well as the U.S. Forest Service firefighting base operations area. Legend also has three fuel carts. One cart contains 100LL at Guidance Helicopters which is manned by Guidance personnel under the training and auspices of Legend. The second cart contains Jet‐A, and is located at Embry Riddle Aeronautic University ramp. It is manned by Legend employees. The third cart also contains Jet‐A. It is located at Legend Aviation, and is manned by Legend and Native Aire personnel under the training and auspices of Legend. Guidance Aviation performs self fueling of its own aircraft using a pickup truck mounted tank and pump dispensing auto gas. Capacity is less than 55 gallons on the tank. Fueling takes place on the Guidance Aviation ramp. Areas where on‐ramp aircraft fueling takes place are indicated by Location Index O on Exhibit 3 – multiple locations. Potential contaminants: 100‐octane Low‐Lead Aviation Fuel; Jet‐A Aviation Fuel; automotive grade gasoline
D Commercial Service Aircraft De‐Icing Activities and Storage (Map Location Index D and Figure D) Commercial service (airline) aircraft are de‐iced on the air carrier apron, located adjacent to the Terminal Building. This apron area drains to three catch basins into the Airport’s subsurface drainage system, terminating at the Detention Basin at the northeast end of the Airport property (Map Location Index N and Figure N). Propylene glycol de‐icing fluid is stored on the apron at the location shown in Figure D. Airline personnel perform their own deicing service. The estimated annual quantity of glycol deicing fluid used by the airlines is less than 350 gallons. Legend Aviation also provides de‐icing service on an as needed basis to General Aviation aircraft. The estimated annual quantity of glycol deicing fluid used by Legend is less than 150 gallons. Areas where on‐ramp aircraft de‐icing takes place are indicated by Location Index O on Exhibit 3 – multiple locations.
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)

The de‐icing season may run from mid‐November through mid‐April. Potential contaminants: Propylene Glycol de‐icing fluid
E Embry Riddle Aeronautical University (ERAU) De‐Icing and Aircraft Washdown Activities (Map Location Index E and Figure E) ERAU de‐ices its fleet of general aviation training aircraft on its ramp using portable trailer mounted equipment. The ERAU ramp drains to a catch basin at the north end of their ramp, and into the Airport subsurface drainage system, terminating at the Detention Basin at the northeast end of the Airport property. ERAU stores its de‐icing chemicals (propylene glycol) on the trailer mounted equipment, parked on its ramp. The estimated annual quantity of glycol deicing fluid used by ERAU is less than 150 gallons. ERAU aircraft are fueled by truck on the ramp by Legend Aviation (see paragraph C, above). Aircraft are washed in a hangar at the north end of the ERAU lease holding. Wash water drains to a hangar floor drain that is routed to an oil/water separator. The waste water then drains to the sanitary sewer system. The oil/water separator is inspected and cleaned out every six months. Potential contaminants: Propylene Glycol de‐icing fluid; Jet‐A Aviation Fuel (potential for spills during truck refueling in this area); petroleum product residue from aircraft washing.
F U.S. Forest Service Fire Retardant Storage, Loading and Disposal (Map Location Index F and Figure F) The U.S. Forest Service facilities include two aircraft fire retardant loading ramps (“pits”), fire retardant chemical storage tanks, a water storage tank, and a fire retardant evaporative lagoon. When the facility is in fire season operation, aircraft arrive and depart on a quick turn‐around basis, and are loaded with chemical retardant and refueled at the loading pits. The two concrete‐paved loading pits drain to catch basin inlets that flow to the retardant evaporative lagoon via an underground pipeline. Aircraft are washed down during the reloading operations, and chemical retardant residue drains to the catch basin inlets and to the evaporative lagoon. The evaporative lagoon is double lined with a plastic membrane, and is equipped with a leak monitoring system. The evaporative lagoon primarily uses evaporation to keep from reaching capacity but can be pumped out using pumper trucks. The lagoon has no gravity flow outlet. The USFS aircraft are fueled by trucks operated by Legend Aviation. The fire season is generally from July through October.
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)

During the off‐season, drainage from the loading pits is diverted to a drainage ditch north of the fire base by a manually operated valve (see Figure F). During recent site inspections, ADEQ expressed concern regarding the visible retardant chemical residue (red iron oxide) present in the drainage ditch just north of the pipe outlet. Since that time, the Forest Service has instituted a policy of thoroughly flushing the drain lines to the evaporative lagoon prior to diverting pit drainage to the drainage ditch. The retardant used by the Forest Service is Phos‐Chek LC‐95A, manufactured by ICL Performance Products LP. The product is delivered and applied as a water‐borne slurry. The chemical makeup (by weight) of the retardant material is 85% Ammonium Polyphosphate, less than 5% Attapulgus Clay, less than 5% Iron Oxide, and less than 8% performance additives. ICL Performance Products LP is withholding the specific chemical identity of the performance additives under provision of the OSHA Hazard Communication Rule ‐ Trade Secrets (1910.1200(i)(1)). ICL Performance Products provides safety and handling information for their Phos‐Chek material. They recommend spill containment as follows: “Contain large spills with dikes and transfer the material to appropriate containers for reclamation or disposal. Absorb remaining material or small spills with an inert material and then place in a chemical waste container. Flush residual spill area with water.” ICL Performance Products adds the following regarding discarding Phos‐Chek material: “This product when discarded is a hazardous waste due to one or more hazardous characteristics (D004, D006, D007) as that term is defined by the Resource, Conservation and Recovery Act (RCRA), 40 CFR 261. Certain recycling activities may qualify for an exemption from RCRA. Consult your attorney or appropriate regulatory official for information on disposal and on the recycling exemption. Recycle or dispose of in accordance with local, state, provincial, and federal regulations.” (all quotes from ICL Performance Products LP Safety Data Sheet for Phos‐Chek LC‐95A, December 3, 2010). The chemical retardant is stored in three 10,000 gallon tanks on the mixing pad adjacent to the operations building. Actual volume of LC‐95A retardant in the tanks varies over the year. A fourth tank on the mixing pad, that has a 5,000 gallon capacity, is used as an offload tank in the event that mixed slurry needs to be unloaded from an aircraft and stored for a short time. The offload tank is normally empty. A fifth tank, with a 5,000 gallon capacity, is a water storage surge tank that is used to store water for mixing with the retardant as it is being delivered to load aircraft. The fire retardant is piped underground from the mixing pad storage tanks to the aircraft loading pits. Potential contaminants: Phos‐Chek LC‐95A Ammonium Phosphate based chemical fire retardant; Aviation Fuels (potential for spills during aircraft refueling by truck in this area); petroleum product residue and detergents from aircraft washing.

G Northaire General Aviation Fuel System (Map Location Index G and Figure G) A 12,500 gallon 100 Low Lead aircraft fuel storage and dispensing system is located adjacent to the Northaire hangar. The storage tank and pump are encompassed by concrete‐filled pipe bollards, but are not located within a containment sump. The fueling area drains to the northeast on the parking apron, and into the Airport’s subsurface storm drainage system. Northaire’s fuel system is only operated by Northaire personnel. Potential contaminants: 100‐octane Low‐Lead Aviation Fuel
H Aircraft Wash Area (Map Location Index H and Figure H)
Based aircraft are washed on the apron west of the Terminal and hangar area. Wash water drains across the apron and into catch basins that drain to the existing Detention Basin via the Airport’s subsurface storm drainage system. In addition to the designated aircraft wash area, some of the hangars have water service and external hose bibs. Currently the Airport does not restrict where aircraft washing can occur. Potential contaminants: Petroleum product residue from aircraft washing; detergent in waste wash water; degreasing compounds in waste wash water.
I West End Apron Detention Basins (Map Location Index I and Figure I) The Airport has installed rock‐lined detention basins along the west edge of the aircraft parking apron at the west end of the airfield. These basins are used for snow removal storage and also function as interceptors for overland drainage from a portion of the Runway 3R safety area, as well as overflow drainage from a small portion of the adjacent golf course during high intensity storm events. Any contaminants that enter the detention basins will drain into the soil beneath the rock lining. Potential contaminants: Roadway petroleum product residue; propylene glycol deicing residue from snow storage.
J Emergency Generator Fuel Storage (Primary Airport Electrical Vault) (Map Location Index J and Figure J) The Airport’s primary electrical vault has a double walled 250 gallon diesel fuel storage tank for necessary back up power in the case of an electrical blackout at the airport. This tank is not located within a containment sump. A spill from this tank would result in fuel draining into the soil. Potential contaminants: Diesel fuel
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)
11
K Emergency Generator Fuel Storage (Secondary Airport Electrical Vault) (Map Location Index K and Figure K) The Airport’s secondary electrical vault has a double walled 145 gallon diesel fuel storage tank that is located within the generator’s weatherproof enclosure. The generator enclosure is installed on a concrete pad, but it is not located within a containment sump. A spill or puncture of this tank would result in the loss of fuel directly into the surrounding soil. Potential contaminants: Diesel fuel
L U.S. Forest Service Operations Facility Service Ramp (Map Location Index L and Figure L)
The U.S. Forest Service (USFS) facility’s concrete service ramp surface drains to a single catch basin that drains via a pipe culvert to a drainage ditch to the north of the USFS facility, toward the fire retardant evaporative lagoon. Storm water from this facility ultimately drains to the Airport’s main detention basin at the northeast end of the airfield. The concrete area is mainly used to clean and re‐package items before they are restocked in the adjacent warehouse. Vehicle washdown does not take place in this area and petroleum products are not stored or used in this area. Stocked items are pressure washed and hose rinsed on the concrete area. Potential contaminants: Potential undetermined contaminants/detergent in wash water (NOTE: In their review of the Draft version of this document on 3/26/2012, the USFS has stated that “The potential for undetermined contaminants/detergents is none to very slight. In 20 years of operation, no chemicals or contaminants have been used in the area which drains to the catch basin and outfall discussed here.”)
M Emergency Generator Fuel Storage (FAA) (Map Location Index M and Figure M) The FAA emergency generator is located adjacent to the Air Traffic Control Tower. The generator is fueled by a double walled 1,000 gallon diesel fuel tank. The tank is not located within a containment sump. A spill from this tank would result in fuel draining into the soil. Potential contaminants: Diesel fuel
N Storage of Hazardous Materials in Hangars (Map Location Index P – multiple locations) Although the current hangar leases do not specifically limit what can be stored in leased aircraft storage hangars, the fire code does specify limits and restrictions. In accordance with the fire code, hazardous materials are not permitted to be stored in hangars (with the exception of fuel in the stored aircraft’s tanks). The Airport has the authority to inspect all hangars, and inspections are carried out semi‐annually. No fueling of aircraft is allowed in hangars.
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)

4. BEST MANAGEMENT PRACTICES (ACTION PLAN) 4.1 Best Management Practices Baseline Narrative (Current BMPs in Place)
This section contains a summary of the Airport’s current documented Best Management Practices (BMPs). A Good Housekeeping
Vehicle and aircraft maintenance and storage areas are cleaned frequently and minor spills of fuel and oil products are cleaned immediately. Discarded shipping materials are either recycled or disposed in dumpsters that are emptied weekly.
B Preventive Maintenance
Catch basins and oil/water separators are inspected and cleaned every six months or after every spill. All manual valves on airport property are inspected and verified to be closed every month. Fuel handling trucks and equipment are visually inspected daily for leaks by the owner tenants. Equipment valves and connections are routinely tested according to the manufacturer’s recommendations. Tenants inspect their own deicing equipment on a seasonal schedule. Fuel, oil, and deicing chemical storage facilities are routinely inspected for leaks.
C Visual Inspections
The Airport Manager is responsible for maintaining qualified inspection and maintenance personnel. The Airport Manager receives all inspection and maintenance reports and keeps a log of follow‐up activities.
D Spill Prevention and Response
Spills that may impact storm water quality would primarily involve the fuel handling, oil storage, deicing/anti‐icing activities, U.S. Forest Service chemical fire retardant operations, and vehicle/aircraft maintenance operations. Exhibit 3 in the Appendix shows the locations of these activities, and they are described in Section3, Site Assessment, above. Major spills would ultimately drain to the Airport’s storm drainage system that discharges into the main detention basin at the northeast end of the airfield (see Figure N in the Site Assessment section). The discharge point for the detention basin is also referenced on the site map (Exhibit 3). The Airport’s current fueling procedure guidelines for secondary containment and spill remediation require that secondary containment be provided for all stationary tanks and during bulk fuel transfer operations as defined in IFC 2006. Secondary containment is not required during dispensing operations. Spill remediation is conducted by the tenants/responsible party in accordance with industry standards and includes but is not limited to the following:
1) Secure the source of the spill,
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)
21
2) Place spill containment, 3) Notify Airport Operations (for spills over one gallon) 4) Notify the Prescott Fire Department (for spills over 5 gallons), 5) Remove contaminated materials, 6) Provide documentation to the Airport Department via the Airport’s standard
spill report form for all spills (this form is included in the Forms section of this document, following the Appendix)
Tenants are responsible for their activities and associated remediation/collection. The Airport does maintain a small quantity (approximately five 5 gallon buckets) of spill absorbent and some oil mats. Supplemental materials are provided by Fire Department response and/or the tenant. The Airport currently has no specific protocol for deicing chemical spill response and excess overspray collection. Tenants are responsible for their activities. The City of Prescott has a vacuum truck that can be used for collecting excess propylene glycol deicer (a Tymco 600 Regen Air Vac Sweeper). The U.S. Forest Service currently does not have a written retardant spill control action plan. Small retardant spills (50 gallons or less) are expected as part of normal mixing and loading operations and are cleaned up by washing them to the drains and the evaporative lagoon. Moderate spills (more than 50 gallons, less than 2,000 gallons) can be contained on the loading and mixing pads and can be handled with washdown procedures and drainage facilities on site. Larger spills would overwhelm the USFS’s ability to handle them and would trigger a response by a spill cleanup team, probably a HAZMAT contractor who is likely to be equipped to handle liquid spills.
E Sediment and Erosion Control
Silt fencing is used in unpaved drainage ditches during minor site work and pavement repairs. When construction activities involve five acres or more of land disturbance, a NOI is filed for coverage under the NPDES General Permit for storm water discharge associated with construction activities. For this case, a separate "construction activity" SWPPP is developed by the contractors to address the requirements.
F Management of Runoff
The Airport property primarily drains to the Airport Detention Basin located at the northeastern end of the property (see Figure N in the Site Assessment section). Storm water runoff is directed to the Detention Basin via a system of storm sewer and drainage ditches. The Detention Basin outfalls into a wash via a 36” outlet pipe, and ultimately to the receiving water, Granite Creek. A portion of the hangar areas along the north edge of the Airport property drain to the north with outfalls to Bottleneck Wash. This wash runs adjacent to the Airport’s northwestern property line, also ultimately draining into Granite Creek.
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)

4.2 Source Specific Maintenance BMPs and System Improvements This section contains the Airport’s selected Best Management Practices (BMPs), as implemented in this SWPPP. The following BMPs are presented as minimum guidelines that must be followed by the Airport and Tenant facility owners/operators. Each facility owner/operator is responsible for developing and maintaining a Spill Prevention Control and Countermeasures Plan that is specific to their operations. In addition to the BMPs that are currently in place, the following source specific maintenance and system improvements will be implemented: A Fuel Spill Containment at Storage and Tank‐to‐Aircraft Delivery Locations
The Airport will require the construction and/or use of impermeable fuel spill containment systems at all existing and new fuel storage tanks and fixed delivery system facilities in conformance with applicable codes, rules and regulations, as may be amended, including but not limited to the City Fire Code as it relates to Bulk Transfers. Examples of acceptable methods of compliance for fuel spill containment systems include but are not limited to the following or a combination of thereof: 1. Permanently constructed facilities designed to contain a spill of the volumes
specified in the applicable codes, rules, and regulations through the use of liquid‐tight sloped or recessed floors with liquid‐tight raised or recessed sills or dikes AND the use of sumps and collection systems
2. Use of temporary or portable containment sumps designed and capable of containing within its boundaries the entire vessel utilized in the bulk transfer operation as well as containing a spill of the volumes specified in the applicable codes, rules, and regulations provided that the second vessel utilized in the bulk transfer operation meets one of the examples contained herein, any bulk transfer is immediately attended by a qualified person, and a spill kit capable of recovery of no less than 100 gallons of the material being transferred is easily accessible and readily available during the bulk transfer operation.
3. Other approved engineered systems designed and capable of containing a spill of
the volumes specified in the applicable codes, rules, and regulations which must be approved and accepted by the City Fire Marshal, Chief Building Inspector, Airport Manager, and the City Risk Manager.
All permanent containment sumps at fuel storage and delivery facilities will be equipped with auto close manual valves for sump drainage pump connections. At tank‐to‐aircraft delivery locations, a spill kit capable of recovery of no less than 100 gallons of the material being dispensed is easily accessible and readily available during the dispensing operation.
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)
23
Containment improvements for existing facilities may be constructed as a phased program, with the containment improvements to be completed no later than July 1, 2017. In the interim, the facility owners/operators will make easily accessible fuel spill kits available at each fuel storage and delivery location. The spill kits shall be located within 25 feet of all stationary fueling stations, fuel transfer stations, and mobile fueling units. At a minimum, spill kits shall include:
Oil absorbents capable of absorbing 15 gallons of fuel
A storm drain plug or cover kit
A non‐water containment boom, a minimum of 10 feet in length with a 12 gallon absorbent capacity
A non‐metallic shovel
Two five‐gallon buckets with lids B Aircraft and Vehicle Washing
The Airport will restrict the use of non‐biodegradable products for all aircraft, vehicle, hangar and shop floor washdown on the airport property. This will be accomplished by modification of existing tenant leases, and addition of new requirements and restrictions in new leases. When able, the Airport will facilitate construction of an Aircraft Wash Facility with a concrete sump that drains to an oil/water separator before passing rinse water to the storm drainage system. All aircraft and vehicle washing will be restricted to this facility.
C Aircraft Fueling From Trucks and Carts Tenants engaging in on‐ramp fueling of aircraft from trucks or carts will be required to have Airport approved spill kits on hand at the fueling location during all fueling operations (see Section 4.2, paragraph A for a description of the minimum spill kit contents). Tenants engaging in on‐ramp fueling activities will also be responsible for providing (constructing and/or maintaining) appropriate containment parking for trucks and fueling carts. Fuel trucks and carts will be parked only in the containment structures except when fueling operations are in progress. As airfield/facility improvements are made, oil/water separators and depressed invert sumps will be installed downstream of all storm drain inlets (catch basins) that could intercept fuel spills from on‐ramp fueling operations.
D Aircraft De‐Icing
Tenants engaging in on‐ramp de‐icing of aircraft from trucks or carts will be required to have Airport approved spill kits on hand at the de‐icing location during all de‐icing operations. (see Section 4.2, paragraph A for a description of the minimum spill kit contents).
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)
24
At de‐icing locations where aprons drain directly to catch basins (such as the airline terminal apron and the ERAU apron), catch basins will be modified to include installation of downstream oil/water separators and depressed invert sumps.
E U.S. Forest Service Fire Base Operations At the end of the fire season, the USFS will power wash the paved aircraft loading areas, and retardant lines will be flushed with water until they run clean. During these operations, the diversion valve will be positioned such that drainage is directed to the retardant evaporative lagoon. At the conclusion of cleanup activities, the diversion valve will be positioned such that drainage is directed to the surface flow diversion ditch. A depressed apron should be installed at the end of the pipe culvert that drains the operations area into the surface flow diversion ditch. The depressed apron should be filled with rip‐rap to the flow line.
F U.S. Forest Service Operations Facility Service Ramp Pressure washing and hose rinsing of warehoused items on the USFS service ramp and at the U.S. Forest Service facility will require installation of an oil/water separator after, and depressed invert sump in, the catch basin at the concrete service ramp. A depressed outfall headwall will be installed at the end of the pipe culvert that drains the service ramp into the surface flow drainage ditch.
4.3 Spill Incident Response In order to facilitate rapid response to spill incidents, the facility owners/operators will post signs in a clearly visible location which provide the telephone numbers of the fire department and appropriate emergency response organizations, and the locations of fire extinguishers, spill control equipment, and fire alarms which are in the immediate vicinity of potential spill locations. A Fuel Spill on Asphalt Pavement
Fuel spills resulting from incidents on asphalt paved areas will be mitigated as follows (immediate response mobilization is required): 1. Responsible party will notify the Airport Manager immediately. 2. Airport Manager will notify the Fire Department if necessary (if spill may be 5
gallons or more). 3. Install silt logs immediately downstream of the spill along the edge of pavement (on
pavement surface) and in drainage ditches downstream of the spill area. 4. Install barricades and markings to identify the spill area as hazardous. 5. Lay down absorbent pads and/or material as appropriate to the extent and volume
of the spill (continue until all visible fuel is absorbed). 6. Inspect downstream storm drainage structures to determine if contamination has
taken place. If contamination is found, inspection will continue progressively downstream until no further evidence of contamination is found.
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)
25
7. Clean out any contamination in storm drainage structures. 8. Inspect the pavement surface to determine the extent of fuel permeation into
subsurface soils. 9. If, in the sole opinion of the City, pavement surface damage indicates the probability
of permeation into subsurface soils, coring will be performed by the party responsible for the spill at the direction of the Airport Manager in order to determine the vertical and horizontal plume extent of soil contamination.
10. If coring determines that there has been subsurface soil contamination, pavement will be removed, all contaminated soil will be removed by excavation and disposed of in accordance with ADEQ policy, and repairs will be made.
B Fuel Spill on Concrete Pavement
Fuel spills resulting from incidents on concrete paved areas will be mitigated as follows (immediate response mobilization is required): 1. Responsible party will notify the Airport Manager immediately. 2. Airport Manager will notify the Fire Department if necessary (if spill may be 5
gallons or more). 3. Install silt logs immediately downstream of the spill along the edge of pavement (on
pavement surface) and in drainage ditches downstream of the spill area. 4. Install barricades and markings to identify the spill area as hazardous. 5. Lay down absorbent pads and/or material as appropriate to the extent and volume
of the spill (continue until all visible fuel is absorbed). 6. Inspect downstream storm drainage structures to determine if contamination has
taken place. If contamination is found, inspection will continue progressively downstream until no further evidence of contamination is found.
7. Clean out any contamination in storm drainage structures. 8. Inspect the panel joints to determine the extent of fuel permeation into subsurface
soils. 9. If, in the sole opinion of the City, joint damage or other indicators indicate the
probability of permeation into subsurface soils, coring will be performed by the party responsible for the spill at the direction of the Airport Manager in order to determine the vertical and horizontal plume extent of soil contamination.
10. If coring determines that there has been subsurface soil contamination, pavement will be removed, all contaminated soil will be removed by excavation and disposed of in accordance with ADEQ policy, and repairs will be made.
C Fuel Spill into Unpaved Areas or Drainage Ditches
Fuel spills resulting from incidents on paved areas that are not mitigated before draining into unpaved areas, or spills that occur directly into unpaved areas, will be mitigated as follows (immediate response mobilization is required): 1.

4.4 Record Keeping and Reporting A Past Spills
There were no known past spills on record at the time of preparation of this SWPPP. B Reporting of Spills
The Airport has developed an Airport Spill Report form. This form is included in the Forms section of this document, following the Appendix. The form will be completed and signed by the person reporting the spill after notifying the Airport Manager of a spill incident and initiation of the appropriate spill response actions. The form will be submitted to the Airport Manager within 5 days of the spill incident. The Airport Manager will maintain a record of all spill incidents and spill reports, along with descriptions of the corrective actions taken.
4.5 Employee Training Programs
The Airport will initiate scheduled employee training programs for all Airport employees. This training will be made mandatory for all persons employed on the Airport premises. Tenant Owner/Operators shall develop and be responsible for providing and documenting training programs for their employees. The employee training program will be designed such that each plan component and goal will address the "how" and "why" tasks which are to be implemented. This conveys to the employees an understanding of potential pollutant problems and how their involvement directly affects the effectiveness of the plan. At a minimum, training will address the major topics contained in the SWPPP plan, such as spill prevention and response, good housekeeping, and material management practices. Given the chemical characteristics for certain spilled chemicals, training will address relevant OSHA training requirements for employees responding to spills. Teaching strategies will focus on how employees can prevent spills, respond safely and effectively to an accidental spill, and recognize potential situations which could lead to storm water contamination. Specialized training programs may also be implemented to cover specific topics, such as runway deicing/anti‐icing applications and follow‐up cleanup procedures.
4.6 SWPPP Compliance and Effectiveness Evaluations
The Airport will conduct tri‐annual site evaluations in order to evaluate the effectiveness of the BMPs that are implemented by the SWPPP. These evaluations may warrant revision of plans to provide more effective BMPs or addition and/or deletion of BMPs for new and/or discontinued activities which can generate pollutants. A modified version of the EPA SWPPP Inspection Report, Version 1.0 (January 9, 2007) is included in the Forms section of this document, following the Appendix. The form will be completed and signed by the person who completes the inspection.
Ernest A. Love Field / Prescott Municipal Airport Storm Water Pollution Prevention Plan (SWPPP)
29
The Airport will perform the following inspections at least annually:
Visually inspect storm water drainage areas for evidence of pollutants entering the drainage system;
Look for changes in physical site conditions, onsite activities, and material handling and storage practices;
Evaluate the effectiveness of implemented BMP measures to reduce pollutant loadings and whether additional control measures are needed;
Observe structural storm water management measures, sediment and erosion control measures, and other structural pollution prevention measures to ensure proper operation (e.g., determine maintenance of structural measures); and
Inspect any equipment needed to implement the plan, such as spill response equipment.
Based on the results of the compliance inspection, the SWPPP will be revised as appropriate and any necessary changes to the plan (measures and controls) will be implemented as necessary. Compliance inspection reports will be retained for at least two (2) years after the certification date of the inspection. The report should include inspection results and follow up actions, the date of inspection and the qualified employee who conducted the inspection, and any incidents of noncompliance (or a signed certification that the facility is in compliance with the plan and the permit). All incidents of noncompliance should be documented in the compliance inspection report. Where there are no incidents of noncompliance, the inspection report should contain a certification that the facility is in compliance with the plan. The signed report should be in accordance with the general permit, and kept with the SWPPP.

Instructions
This sample inspection report has been developed as a helpful tool to aid you in completing your
site inspections. This sample inspection report was created consistent with EPA’s Developing
Your Stormwater Pollution Prevention Plan. You can find both the guide and the sample
inspection report (formatted in Microsoft Word) at www.epa.gov/npdes/swpppguide
This inspection report is provided in Microsoft Word format to allow you to easily customize it
for your use and the conditions at your site. You should also customize this form to help you
meet the requirements in your construction general permit related to inspections. If your
permitting authority provides you with an inspection report, please use that form.
For more information on inspections, please see Developing Your Stormwater Pollution Plan
Chapters 6 and 8.
Using the Inspection Report
This inspection report is designed to be customized according to the BMPs and conditions at
your site. For ease of use, you should take a copy of your site plan and number all of the
stormwater BMPs and areas of your site that will be inspected. A brief description of the BMP
or area should then be listed in the site-specific section of the inspection report. For example,
specific structural BMPs such as construction site entrances, sediment ponds, or specific areas
with silt fence (e.g., silt fence along Main Street; silt fence along slope in NW corner, etc.)
should be numbered and listed. You should also number specific non-structural BMPs or areas
that will be inspected (such as trash areas, material storage areas, temporary sanitary waste areas,
etc).
You can complete the items in the “General Information” section that will remain constant, such
as the project name, NPDES tracking number, and inspector (if you only use one inspector).
Print out multiple copies of this customized inspection report to use during your inspections.
When conducting the inspection, walk the site by following your site map and numbered
BMPs/areas for inspection. Also note whether the overall site issues have been addressed
(customize this list according to the conditions at your site). Note any required corrective actions
and the date and responsible person for the correction.
