If the storm water discharge benchmarks specified in the 1200-COLS permit are not achieved, the Port will undertake the following actions: Review the SWPCP and determine if it is being followed within 30 days of receiving the sampling results in accordance with Schedule A.10(a). Identify any additional site controls or corrective actions that are needed. This step may also include a site inspection of facilities and common areas to review industrial activities and determine if any changes have occurred. Document the inspection and the SWPCP review and retain a copy of the documentation in the Port s files. If the review and inspection determines that new site controls are needed, the SWPCP will be updated. Revisions to the SWPCP will only be made to the specific components of the plan that need to be updated. The Port will submit written notification to the DEQ within 30 days for SWPCP revisions in accordance with Schedule A.10 of the 1200-COLS permit. Co-permittees are required to review the SWPCP at least annually as part of the annual verification for compliance with the storm water permit. Permittees must submit any changes or corrections to the SWPCP to the Port within two weeks of identified revisions. Portland International Airport COLS DEQ File No

8 III. Definitions The following provides definitions of pertinent terms and phrases used throughout this document. Benchmarks are guideline concentrations ( levels of concern ) not limitations. They are designed to assist the permittee in determining if the implementation of their SWPCP is reducing pollutant concentrations to below the levels of concern. For facilities that are subject to federal limitations, benchmarks apply to only those pollutants that are not limited by the federal regulations. Best Management Practices (BMPs) refers to secondary containment, structural controls for oil and grease, proper management and disposal of waste chemicals and materials, erosion and sediment control, debris control, storm water diversion away from industrial activities, covering activities, housekeeping practices, and other structural and non-structural controls and practices intended to prevent or reduce pollutants in storm water. Co-permittees are Port of Portland tenants with Standard Industrial Codes (SIC) that require NPDES permit coverage or that have industrial activities, as deemed by the Port, that impact storm water. Discharge outfall or point source refers to any discernible, confined, and discrete conveyance, including, but not limited to any pipe, ditch, channel, tunnel, conduit, well, or discreet fissure from which pollutants are or may be discharged. Impervious surface refers to surfaces that will not allow storm water runoff to infiltrate into the natural ground. Significant materials include, but are not limited to: raw materials; fuels; materials such as solvents, detergents, and plastic pellets; finished materials such as metallic products; deicing and anti-icing chemicals; raw materials used in food processing or production; hazardous substances designated under Section 101(14) of CERCLA; any chemical the facility is required to report pursuant to Section 313 of Title III of SARA; fertilizers; pesticides; and waste products such as ashes, slag and sludge that have the potential to be released with storm water discharges. Site controls include best management practices, spill prevention and response procedures, preventative maintenance, and employee education. The purpose of site controls is to eliminate or minimize the exposure of pollutants to storm water. Spill Prevention Control and Countermeasures (SPCC) regulations (40 CFR 112) establish the procedures, methods, and equipment to prevent the discharge of oil from non-transportation related oil processors and handlers. The objectives of the SPCC plan are to prevent spills from occurring at the facility, prepare for a possible spill, and to respond if a spill does occur. The three basic principles that the Plan encompasses are: 1) the practices devoted to the prevention of oil spills; 2) the plan of containment should a spill occur; and 3) the plan for removal and disposal of spilled oil. The SPCC plan is required for facilities that store petroleum products with a combined storage capacity of greater than 1,320 gallons. Portland International Airport COLS DEQ File No

9 Spill Prevention and Response Procedures (Spill Plan) are methods to prevent spills along with clean-up and notification procedures. These methods and procedures shall be made available to appropriate personnel. The required clean-up material shall be on-site and readily available. Spill prevention plans required by other regulations may be substituted for this provision providing that storm water management concerns are adequately addressed. Storm water runoff means water discharged as a result of rain, snow, or other precipitation. Total Maximum Daily Load (TMDL) is the sum of the individual Waste Load Allocations (WLAs) for point sources and Load Allocations (LAs) for nonpoint sources and background. If receiving water has only one point source discharger, the TMDL is the sum of that point source WLA plus the LAs for any nonpoint sources of pollution and natural background sources, tributaries, or adjacent segments. TMDLs can be expressed in terms of either mass per time, toxicity, or other appropriate measure. Water quality limited means that the body of water does not meet applicable water quality standards.

10 IV. Co-permittees Responsibilities PDX tenants who are a Co-permittee on the PDX 1200-COLS National Pollutant Discharge Elimination System (NPDES) Storm Water Discharge Permit (Appendix A) are listed in Appendix B. Each Co-permittee will comply with the permit and the PDX (SWPCP). PDX tenants within the 1200-COLS permit boundary with industrial activities impacting storm water must become Co-permittees by submitting an application to the Port of Portland (Port). The application form is included in Appendix B. Each Co-permittee is responsible for ensuring that all of its activities are in compliance with the permit, and for complying with all of the following requirements: Implement planned control measures and best management practices identified in the SWPCP. Conduct and document monthly inspections of industrial areas and activities exposed to storm water, storm water control measures, structures, catch basins, and treatment facilities including oil-water separators and catch basin filters in accordance with Schedule B.7. Perform any necessary preventative maintenance of storm water control structures and facilities on leasehold. Submit information related to the Co-permittee s operations and participate in benchmark exceedance investigations if requested by the Port or DEQ. Retain copies of inspection forms, preventative maintenance and repair documentation for a minimum of three years and provide copies to the Port or DEQ upon request. Maintain a written schedule for regular pick-up and disposal of waste materials. Develop and implement a Spill Prevention and Response Plan (Spill Plan). The plan must include methods to prevent spills along with clean-up and notification procedures. Maintain a copy of the Spill Plan and adequate spill clean-up materials on-site at all times. Conduct and document an employee education program to inform personnel of the components and goals of the SWPCP and the Spill Plan consistent with 1200-COLS permit requirements. The education and training should occur at the time of hire and annually thereafter. Review the SWPCP whenever facility operations change. o Ensure activities are adequately represented in the SWPCP for compliance and accuracy. o Submit any revisions or updates within two weeks to the Port s Aviation Environmental Department. Submit a completed and signed annual verification form to the Port certifying that the Co-permittee has performed the required inspections, preventative maintenance, and best management practices and has prevented illicit discharges. Verification forms are sent out to Co-permittees by the Port each year. Portland International Airport COLS DEQ File No

11 V. Introduction A. Background Section 402 of the Clean Water Act (CWA) establishes a program for NPDES Permits. The CWA identifies Standard Industrial Classification (SIC) codes and industrial activities that trigger a requirement for permit coverage under the NPDES program. The Oregon Department of Environmental Quality (DEQ) has created general NPDES permits for many industrial activities; the 1200-COLS permit is one type of general permit issued by the DEQ. The 1200-COLS permit is specific to industries discharging to the Columbia Slough, and incorporates the Total Maximum Daily Loads (TMDLs) for the Columbia Slough. The DEQ has issued the following TMDLs for the Columbia Slough: dissolved oxygen (DO), ph, nutrients (chlorophyll and phosphorus), bacteria, and toxics (organics and lead). Implementation of this SWPCP and compliance with this permit constitute compliance with the TMDL for industrial storm water discharges. The DEQ issued the revised 1200-COLS NPDES Permit on October 1, The permit covers storm water associated with industrial activity occurring on Port of Portland property. Schedule A of the 1200-COLS permit requires the preparation and implementation of a (SWPCP). This document has been updated to meet the new Permit requirements for the Port and Co-permittees. Storm water, process water, and other waste water discharges from PDX are regulated under various other permits. The permits that regulate storm water or other discharges from PDX to the storm water system are listed in Table 1. The permits listed are issued to the Port of Portland or the Port of Portland at PDX and Co-permittees. Portland International Airport COLS DEQ File No

13 B. Purpose This SWPCP is a general guidance document for use by Port personnel and Copermittees to reduce pollutant exposure to storm water. The SWPCP is intended to guide the Port and Co-permittees in evaluating storm water pollution control strategies, maintaining existing storm water collection, diversion or containment structures, and developing and implementing, when appropriate, additional storm water pollution controls. This SWPCP addresses all regulated industrial activities at PDX that are conducted by the Port and Co-permittees. It does not address industrial activities of the Oregon Air National Guard (ORANG), which has its own 1200-COLS permit, although storm water from the ORANG discharges into the Port s storm system. The SWPCP also does not address deicing activities which are regulated under Anti-icing/Deicing Waste Discharge NPDES Permit No (Issued to: Port of Portland at PDX and Copermittees). The control measures outlined in the PDX SWPCP are intended to meet the requirements of Schedule A of the 1200-COLS permit and to address the following requirements of the Port s MS4 permit: pesticide; herbicide and fertilizer use; and illicit discharge detection. If storm water analysis detects pollutant concentrations that exceed 1200-COLS permit benchmark concentrations, an investigation of the source of pollution will be conducted, corrective action will be taken if appropriate, and site controls will be added or changed as necessary, as described in Section II of this plan (Review and Revision Schedule). The SWPCP will be revised to include these changes and submitted to the DEQ in accordance with Schedule A.8 of the 1200-COLS permit. Portland International Airport COLS DEQ File No

14 VI. Site Description PDX occupies approximately 3,246 acres of land and is located in northeast Portland on the south shore of the Columbia River (Figure 1). PDX is owned and operated by the Port. The Port leases space at PDX to many private companies including airlines, cargo carriers, car rental companies, a fueling consortium, and support service providers. A. Location PDX is located at Latitude 45º 35' 21" North and Longitude 122º 35' 46" West. The airport is bordered to the north by the Columbia River, to the south by the Columbia Slough, to the east by Interstate 205, and to the west by NE 33 rd Avenue, as shown in Figure 1. The area is used primarily for aviation related industrial and public airport uses. To the north of PDX are the Columbia River and the City of Vancouver, Washington. The Columbia River shoreline in Vancouver has a mix of single and multi-family residential, commercial, office, and industrial land uses. The south shore of the Columbia includes Marine Drive and a public pedestrian and bicycle trail along the river. To the east of the airport is the Columbia Shore District, industrial/commercial parks and open space. To the southeast are the predominantly residential communities of Maywood Park, Parkrose, Wood Village, and Fairview. To the south of PDX is the Columbia Slough. Between the Slough and Columbia Boulevard, existing land uses include a variety of industries, commercial uses, and open space. Land uses to the west of PDX are predominantly open space and golf courses. To the southwest are a mixture of industries and commercial businesses, as well as a golf course. B. Facility Details Storm water from PDX either discharges directly into the Columbia Slough or into a tributary of the Slough. About 42% of the airport property is covered by impervious roofs, runways, roads, parking lots and other paved areas. The topography at PDX is flat, with the majority of pervious areas covered with grass or other landscaping. There are nine major drainage basins at PDX; three discharge into detention ponds prior to discharging to receiving waters. Domestic water at PDX is provided by the City of Portland. The majority of the airport s domestic waste water discharges to the City of Portland s Columbia Boulevard Waste Water Treatment Plant via the sanitary sewer. However, there are two active septic systems at PDX. The septic system drain fields serve the Ameriflight and BPA facilities are located approximately as follows: (1) on the west side of the airport, southeast of the Ameriflight hangar, east of Elrod Road; and (2) on the west side of the airport, east of the BPA hangar, just northeast of Elrod Road. C. Site Map An airport facility map showing the location of the Port s major industrial activities and tenants is included on Figure 2. Figures 2, 3, and 4 also contain information about: Drainage patterns Drainage and discharge structures Outline of the drainage area for each storm water outfall Portland International Airport COLS DEQ File No

15 Paved areas, equipment, tanks and buildings within each drainage area Areas used for outdoor manufacturing, treatment, storage, and/or disposal of significant materials Existing structural control measures for reducing pollutants in storm water runoff (see Figure 3) Storm water features to reduce flow or minimize impervious surfaces Material loading and access areas Used oil, hazardous waste treatment, storage, and disposal facilities Location of wells including waste injection wells, seepage pits, dry wells, etc. (see Figure 4. The Port does not have any waste injection wells, seepage pits, or dry wells at PDX) Location of springs, wetlands and other surface water bodies, and Location of spill kits (there are also a number of mobile spill kits) Location of sampling points and outfalls Location of spill prevention and clean up materials (mention mobile spill kits and drain covers) D. Drainage Area Descriptions PDX s drainage system is divided into nine drainage areas (see Figure 2). Each drainage area has one major discharge outfall where storm water leaves PDX property. Detailed descriptions of each area including a summary of the Port s and Co-permittee industrial activities within each basin are provided below. Summary information on each drainage area is provided in Table 3. Impervious areas: the total acreage owned by the Port is approximately 3,246 acres. The total drainage area discharged through the Port s outfalls is approximately 3,865 acres, which includes runoff from areas not owned nor managed by the Port. Examples of areas not owned or managed by the Port include public roadways and privately owned parcels. Not all of the acreage owned by the Port is included within the airport s permit boundary. For example, the Oregon Air National Guard leases land from the Port, and tenants with isolated drainage basins located on Alderwood Road have their own 1200-COLS permit. The total acreage within the permit boundary is approximately 2,781 acres; of this acreage, the total impervious area within the permit boundary is 43.0% or 1,163 acres and includes buildings, runways, parking lots, or structures operated or occupied by the Port or its tenants. Table 2 provides a description of each drainage area and identifies the estimated impervious area within the permit boundaries for each drainage area. Note that drainage area estimates are limited to pervious and impervious surfaces within the boundaries of the PDX permit because in some instances the drainage basin boundary extends to areas not owned or controlled by the Port or Co-permittees.

19 E. Receiving Waters Storm water at PDX is collected through a series of drainage ditches and storm water pipes that discharge into the middle reach of the Columbia Slough or its tributaries. The waters of the Slough are pumped or gravity flow to the lower Slough via the Drainage District (MCDD) pump station #1. The lower Slough, which is tidally influenced, flows into the Willamette River near its confluence with the Columbia River. In addition, PDX has one outfall to the Columbia River for discharging deicing storm water runoff. This outfall is permitted under Anti-icing/Deicing Permit # and is not addressed in this SWPCP. A set of Total Maximum Daily Loads (TMDLs) has been established for the Columbia Slough. The parameters of concern in the TMDL include dissolved oxygen (DO), ph, nutrients (chlorophyll and phosphorus), bacteria and toxics (organics and lead). The DEQ has incorporated benchmarks for specific pollutants based on TMDL load allocations into the 1200-COLS permit. Under the Lower Willamette sub-basin TMDL, the Port is also named as a Designated Management Agency for temperature on the Columbia Slough. Portland International Airport COLS DEQ File No

20 VII. Underground Injection Control Rules and Regulations The Oregon Administrative Rules (OAR) regulate the discharge of waste, including storm water discharges, into underground injection control (UIC) systems. The 1200-COLS permit requires that all permittees comply with these regulations. It is the Port s policy that no new UICs be created when there are other means of disposal available (i.e. storm water system, sanitary system, off-site disposal). If a UIC is the only option, it must be approved in writing by the Port, and it shall be constructed, registered and operated in accordance with the UIC rules and regulations to protect groundwater. There are currently no known UICs at PDX. Portland International Airport COLS DEQ File No

21 VIII. Schedule E Sector Specific Requirements The primary industrial activity at PDX is classified under SIC codes This classification requires compliance with additional technology-based effluent limits in Schedule E Sector S Air Transportation Facilities of the 1200-COLS NPDES permit. Good Housekeeping Measures E.S through E.S and Additional SWPCP Requirements E.S.2.1 through E.S.2.3 are addressed under Section X Site Controls. Sections E.S through E.S.1.2, E.S.2.4 and E.S.3 apply to deicing and anti-icing activities. Deicing and anti-icing operations at PDX are regulated under NPDES permit number and therefore, are not addressed in this SWPCP. Portland International Airport COLS DEQ File No

22 IX. Industrial Activities The Port and Co-permittee regulated activities at PDX have been divided into the following 10 categories: 1. Fueling (Co-permittee) 2. Aircraft, Equipment, Vehicle and Building Maintenance (Co-permittee) 3. Airport Maintenance and Operations (Port) 4. Material Storage and Handling (Port and Co-permittee) 5. Food Services (Co-permittee) 6. Garbage and Recycling Storage (Port and Co-permittee) 7. Fire Station Operations and Training (Port) 8. Aircraft, Vehicle, and Equipment Washing (Port and Co-permittee) 9. Rental Car Fueling, Maintenance, and Washing (Co-permittee) 10. Aircraft and Ground Service Equipment Painting (Co-permittee) The 10 categories of activities or practices that occur at PDX and the type of potential pollutants generated are discussed below. The types of industrial activities conducted by PDX tenants who are Co-permittees under the Port s 1200-COLS permit are listed in Table Fueling (Co-permittee) Jet-A fuel is pumped to the PDX fuel farm via an underground pipeline, owned and operated by Kinder Morgan, from the Willbridge Terminal located in North Portland. PDX s fueling distribution system, including the fuel farm, is owned by Portland Fueling Facilities Corporation (PFFC) and operated by Aircraft Services International Group (ASIG). ASIG conducts fueling operations for all carriers at PDX with the few exceptions noted below. The fuel farm is located at the northwest corner of the airport and consists of three aboveground storage tanks (ASTs) with a total capacity of 3,400,000 gallons of jet fuel. Two tanks have a capacity of approximately 860,000 gallons each; the third tank has a capacity of about 1,680,000 gallons. Generally, at any given time, one tank receives fuel, one is full but idle, and the other is used to provide fuel to the distribution system. Underground pipelines are used to distribute fuel to the terminal gates. All airport gates at Concourses B, C, D, and E, except the A Gates and Gate E6, have a fuel hydrant system installed on-site. ASIG performs fueling and metering operations between the hydrant system and the aircraft. Aircraft at Concourse A Gates and Gate E6 are fueled by ASIG mobile fuel trucks. ASIG also conducts fueling operations using mobile fuel trucks for Boeing, ATI, and the cargo airlines at Airtrans facilities, UPS, Fedex and DHL, Ameriflight, Evergreen EAGLE, Atlantic, and 533 MA LLC conduct fueling from storage tanks that they own and operate. There are two jet fuel islands owned by PFFC and operated by ASIG at PDX. One fuel island is located adjacent to the Ground Run-up Enclosure, west of Taxiway J. The second fuel island is located on the east end of Concourse E and drains to an oil-water Portland International Airport COLS DEQ File No

23 separator with an emergency shut off valve. The fuel islands provide jet fuel to mobile fueling trucks. PFFC also owns two remote gasoline stations for fueling ground service equipment (GSE), one on the north side and one on the south side of the airport. The north GSE fuel station is located at the east end of the E concourse and the south GSE fuel station is located to the west of the United States Post Office. The concrete drive pads adjacent to the both gasoline dispensers drain to an oil-water separator. Several tenants have separate aboveground storage tanks (ASTs) or underground storage tanks (USTs) to store fuel such as aviation gasoline or diesel. These fuel storage tanks are supplied by truck deliveries and dispensed by mobile fuel trucks. Potential pollutants from fueling include diesel, gasoline, jet fuel, and metals. Each Co-permittee is responsible for determining whether their operations trigger Spill Prevention Control and Countermeasure (SPCC) Plan requirements. The development and implementation of an SPCC Plan, if required, is also the responsibility of the Copermittee. However, every Co-permittee is responsible for the development and implementation of a spill response plan specific to their operations as required by the 1200-COLS permit. 2. Aircraft, Equipment, Vehicle, and Building Maintenance (Co-permittee) Routine aircraft maintenance is generally performed outdoors on the ramps. However, a few tenants have their own aircraft maintenance facilities located at PDX; these tenants include Atlantic, Horizon, Skywest (d.b.a. United Express), Bonneville Power Administration (BPA), and Ameriflight. In addition, materials and equipment may be stored inside or outside undercover. These materials include, but are not limited to, drums, tanks (containing hydraulic fluid, and fuel), and electrical transformers. Building maintenance includes floor sweeping and washing activities. The sanitary wastes from aircraft holding tanks are disposed of into the sanitary sewer system in specially designated locations. However, there is the potential for contamination from spills that occur while handling sanitary wastes during aircraft offloading and transport. Ground Service Equipment (GSE) maintenance is performed by a number of Copermittees. GSE may include vehicles, bag carts, tugs, belt loaders, or other equipment used in aircraft operations. Maintenance occurs both outdoors and indoors. The following Co-permittees have their own equipment maintenance facilities: United, Horizon, SkyWest, BPA, Aircraft Terminal Services, American Airlines, and EAGLE. Other Co-permittees may contract with one of these companies or hire an outside company to conduct equipment maintenance either on-site or off-site. Potential pollutants from aircraft, vehicle, equipment and building maintenance include fuel, new and used oil, antifreeze, solvents, hydraulic fluid, brake fluid, paints, metals, degreasers and solid wastes. Potential contaminants from sanitary waste spills include bacteria, ammonia, phosphorus, biochemical oxygen demand (BOD) and nitrogen. Portland International Airport COLS DEQ File No

24 3. Airport Maintenance and Operations (Port) PDX maintenance staff is responsible for maintaining the airport infrastructure. Maintenance activities include painting, significant materials storage, materials handling, hazardous waste storage and handling, and fueling and fuel transfers. PDX currently operates three maintenance facilities at PDX: the Maintenance Compound, the Maintenance Annex, and the Central Utility Plant (CUP). PDX MX is also responsible for maintaining emergency generators for the terminal and deicing plant. The following narrative provides descriptions of the industrial activities conducted at these sites. PDX deicing staff operates the Deicing Treatment Plant. All chemicals associated with the treatment process are stored inside the treatment plant with secondary containment. Vehicle fueling: there is one vehicle fueling area for facility vehicles and equipment. The fuel island is located northwest of Building Number 7111 and is partially covered. The fuel island is drained by strip drains on the north and east sides which direct flow to an oil-water separator then to the storm water system. The oil-water separator has an emergency shut off valve so that if a large fuel spill were to occur, it would be contained within the separator. Storage Tanks: o Fuel Island - One 6,000-gallon unleaded gasoline UST, one 6,000-gallon diesel UST and one10,000 -gallon diesel UST. All USTs are equipped with spill protection, leak detection, corrosion protection, overfill alarm and shutoff system. o Vehicle Maintenance Building - A double-walled 500-gallon aboveground used oil storage tank is located outside on the southeast side of the vehicle maintenance building. Used oil, brake, and hydraulic fluid from the vehicles are collected and poured into a drain, inside the building, leading to the used oil tank. The used oil is recycled. A 500-gallon motor oil AST is located inside the vehicle maintenance building. o Maintenance Compound Emergency Generator - A 500-gallon double-walled AST containing diesel for the emergency generator is located to the east of the loading dock area of Building o Central Utility Plant (CUP) - Two 30,000-gallon USTs containing fuel oil are located within a fenced area on the north side of the CUP. There is also a 6,000- gallon UST containing diesel fuel located on the west side of the building. The fuel oil tanks are used only in emergencies when the natural gas lines are out of service. The USTs feed small ASTs within the building (known as Day Tanks) associated with the generators. UST refueling occurs outside and this is the only activity with the potential to impact storm water. The Port performs line tests and tests of the cathodic protection system, where applicable, for these USTs annually. o Deicing Treatment Plant - An emergency generator located on the east side of the treatment plant includes an internal 980-gallon diesel storage tank. o Concourse C - A 500-gallon diesel emergency generator located at gate C-4. Process and waste water: vehicles and equipment are washed in one of two covered areas at the PDX Maintenance Facility: 1) the wash bay, or 2) the re-circulating wash rack. Portland International Airport COLS DEQ File No

25 Both of these areas drain through oil-water separators into the sanitary system. Pressure washing of engines is also conducted in the wash bay. Other waste waters, such as latex paint rinse water and asphalt tack rinse water are discharged to the sanitary system via the wash bay. Solids containment area: sweeper and vactor trucks unload solid waste material into a designated solids containment area, located in the southwest corner of the PDX Maintenance Facility. Residual liquids in the solids are allowed to drain to the sanitary system. The solids are profiled and permitted for disposal at a licensed landfill. Potential pollutants generated from airport maintenance activities at PDX include fuel, oil, paint, detergents, solid wastes, bacteria, metals and sediment. 4. Material Storage and Handling (Port and Co-permittee) There are several locations throughout the airport where fuel, oil, and wastes are stored in ASTs or USTs. The largest ASTs at PDX are used for storing aviation fuel and are owned by PFFC. The Port owns a number of ASTs, 10 of which are located outside. The remaining ASTs shown on Figure 2 are tenant-owned. Port-owned ASTs that are located indoors with containment are not shown on the figure. The ASTs contain a variety of compounds, including oil, propane, fuel, transmission fluid, hydraulic fluid, and firefighting foam. A list of ASTs, including location, content, and size of each AST, is included in Appendix C. There are also Port- and tenant-owned active USTs located at PDX. Because the USTs are below ground, they do not represent a significant source of potential storm water pollutants. However, overfilling and spilling when the USTs are refilled can lead to storm water contamination. Potential pollutants from these activities include fuel, oil and grease, and firefighting foam. 5. Food Services (Co-permittee) There is one in-flight catering company, Sky Chef s, located at PDX that serves the airlines. Several airlines, such as Horizon, provide their own food. Sky Chef s has a food preparation facility located at PDX. Food wastes are contained in carts or sealed plastic bags during aircraft off-loading. The food wastes are then transported to food services companies by trucks and stored in compactors before they are picked up and disposed off-site by licensed contractors. Potential pollutants related to food processing activities include fuel, oil and grease, nutrients, bacteria, BOD, and ph. 6. Garbage and Recycling Storage (Port and Co-permittee) The Port is responsible for garbage storage and disposal at the terminal building, Central Utility Plant, the PDX Maintenance Facility, some tenant facilities, PDX Cargo Center, and the parking and taxi holding areas. The storage containers are all fully enclosed, covered, or stored undercover where feasible. Tenants not serviced by the Port are responsible for their own waste storage and disposal. Tenants and Port staff are discouraged from placing ice in garbage and recycling containers. The preferred method is to let the ice melt in a sink, on grass, or directly over Portland International Airport COLS DEQ File No

26 a sanitary drain to minimize any pollutants that may be picked up by the ice melt. There is potential pollutant exposure to storm water from uncovered garbage. Garbage can contain materials which could contribute to storm water pollution, such as oil and grease, nutrients, BOD, heavy metals, bacteria, and other significant materials disposed of improperly in garbage receptacles. 7. Fire Station Operations and Training (Port) The PDX fire station is located in the northwest corner of the airport. A 2,000-gallon diesel double-walled AST is located at this site. Storm water from the vicinity of the tank flows through an oil-water separator prior to discharge to the storm system. All other significant materials are stored inside the garage and work area and are not exposed to precipitation. Washing of equipment and vehicles is conducted inside the garage where the water drains through an oil-water separator to the sanitary system. In addition to the fire station, a live Fire Training Facility (FTF) is located near the northwest corner of the airport. The FTF consists of a live fire burn area, two 2,000-gallon JP-4 fuel ASTs, one 400-gallon JP-4 and water AST, sprinkler system, control system, an oil-water separator, and two 20,000-gallon ASTs. One of the 2,000-gallon ASTs is owned and operated by the ORANG. The ASTs are surrounded by a concrete secondary containment structure. A sump inside the containment structure drains any spilled fuel into the adjacent oil-water separator. The burn area is a lined, gravel-filled depression approximately 100 feet in diameter that contains several fuel sprinklers, and a drain box. Fuel for the burn pit is provided by two ASTs (used for jet fuel fire practice). A second, propane fired system is also present and is used more frequently than the jet fuel system. When training exercises occur, the burn pit is first partially filled with water. Fuel from the ASTs or propane system is pumped to the burn pit and ignited. When the exercise is complete, the fuel supply is cut off and the water in the burn pit is drained into the adjacent oil-water separator. Residual fuel from the oilwater separator is collected in a 400-gallon AST and re-burned in the pit. Water collected in the oil-water separator is pumped to one of the two 20,000-gallon ASTs and stored for reuse in the next exercise. This is a closed loop system. Other activities that may result in potential pollutants to the storm system include the infrequent discharge of firefighting foam. The firefighters are required to test the composition of the firefighting foam discharged by the fire vehicle turrets on an annual basis. When this occurs, a limited amount of the 3% foam mixture is sprayed onto a grassy area. 8. Aircraft, Vehicle and Equipment Washing (Co-permittee) Alaska Airlines utilizes a collection system to collect aircraft wash water. Horizon Air and Atlantic both have aircraft wash pads which drain to the sanitary system utilizing a valve to divert flow from the storm system. United Airlines and the car rental facilities have individual vehicle and equipment wash pads or wash racks which drain to the sanitary system. Other tenants utilize a collection method to wash equipment, vehicles or aircraft. The ORANG maintains a DEQ issued1700-a wash water permit. Waste water from Portland International Airport COLS DEQ File No

27 ORANG washing operations are discharged into PDX drainage basin Rental Car Fueling, Maintenance and Washing (Co-permittee) Five rental car operators (Avis, Budget, Dollar, Hertz, and Enterprise) are located on-site to serve PDX. The Quick Turn Around (QTA) area is located on the south side of the airport parking garage. The QTA is used by all five of the rental car agencies who operate independently out of the five-bay facility. The majority of refueling and car washing is conducted at the QTA. The fueling area is covered and the washing facilities drain to the sanitary system. Rental car maintenance, detailing, and some washing in wash racks are conducted at each operator s individual facility located on NE Airport Way. Each of the rental car operators also has an AST at their individual facilities. The maintenance activities are performed indoors or undercover. Each rental car company owns and operates a gasoline UST at the QTA. Potential pollutants include petroleum products, detergent, antifreeze, metals, and solid waste. 10. Aircraft and Ground Service Equipment Painting (Co-permittee) Aircraft painting is performed at the AMC Maintenance Hangar (4635 NE Cornfoot Road) by Boeing. The work is performed inside the hangar and waste materials are collected, stored in aboveground tanks inside the hangar, and shipped off-site for disposal or disposed of into the sanitary sewer under permit. Several Co-permittees (Horizon and United) perform aircraft parts and GSE painting at PDX. This activity is required by the Port to be performed indoors, and associated waste materials are collected and disposed of properly. The waste containers for this activity are stored inside or outside undercover. Portland International Airport COLS DEQ File No

28 X. Site Controls Due to the nature of airport operations, conventional storm water controls may not be feasible in all situations. In addition, the Federal Aviation Administration (FAA) rules and regulations prohibit the use or construction of certain structures within an active aircraft movement area. Controls that are appropriate, safe, and feasible are used. A. Storm Water Best Management Practices Storm water controls used by the Port and its Co-permittees are described in the following sections. Existing control facilities and practices will remain in place or in effect during the permit period. Additional controls will be implemented, if necessary, based on the storm water sample results, inspections, and a review of this SWPCP. Minimizing Exposure & Containment The types of containment used at PDX to prevent the discharge of contaminants to the storm water drainage system from storage tanks include: (1) berms or curbs around ASTs, (2) double-walled ASTs, (3) water quality improvement ponds at the downstream end of drainage areas, and (4) oil-water separators and shut-off valves to provide containment for spills. The largest ASTs at PDX are used for storing aviation fuel and are owned by PFFC and operated by ASIG. The PFFC tank farm consists of three double-walled ASTs with a total capacity of 3,400,000 gallons that are contained within concrete berms. The drainage pipe exiting the catch basin located inside the concrete berms is equipped with a valve which is normally in the closed position. After storm events the valve is opened and clean storm water, free of odor and sheen, drains through an oil-water separator to a drainage ditch west of the tank farm. Secondary containment will also prevent the escape of the AST contents in the event of a catastrophic tank failure. All Port-owned ASTs are located indoors or have secondary containment, with the exception of propane tanks. There are also Port- and tenant-owned active USTs located at PDX. Since the USTs are below ground, they do not represent a significant source of potential storm water pollutants from catastrophic failure or leaking tanks. However, overfilling and spilling during the use of the USTs can lead to storm water contamination. All Port-owned, regulated USTs have spill and overfill protection. The Port and Co-permittees with USTs are required to have a spill response plan and to comply with state and federal regulations requiring spill and overfill protection for regulated USTs. Smaller amounts of significant materials are typically stored in 55-gallon drums. All Portowned drums containing liquid or solid significant materials are stored indoors at the PDX maintenance facility compound and labeled with the content. Tenants store drums of significant materials either indoors or outside undercover. Solid significant materials are typically stored indoors or undercover to prevent potential contact with storm water. Storm water collected in secondary containment is inspected prior to discharge. If the water is clean and there is no evidence of contamination, the water may be discharged to the storm water system. This inspection should be documented by each Co-permittee for their Portland International Airport COLS DEQ File No

29 individual tanks. If there is evidence of contamination, the water must be disposed of properly. Quiescent water quality improvement ponds located at the downstream end of Drainage Areas 2, 4, and 6 provide additional treatment and also serve as containment for contaminated storm water and spills (see site map, Figure 2). Each quiescent pond is equipped with a valve which is normally in the open position. Storm water from the drainage area enters the pond and is detained for hours or days, depending on flow conditions, before exiting to the Columbia Slough. Absorbent and hard booms are employed in each pond to remove oil and grease and prevent other floatable materials from leaving the pond. Drainage Areas 2 and 6 are equipped with detention ponds as well as quiescent water quality improvement ponds. Although the primary purpose of the detention ponds is to provide flood water storage, temporary containment and treatment of storm water also occurs. Drainage Area 7 drains to McBride Slough before discharge to the Columbia Slough. Absorbent booms installed at the outfall and within the basin limit the discharge of oil and grease or other floatable materials to the channel. Drainage area 7 has a large 44 cartridge storm filter installed about 435 feet from the outfall at the PMF. Minimizing Exposure & Oil and Grease Existing control measures include both source control and structural/treatment BMPs. The source control BMPs consist of spill prevention and control measures. Copermittees conduct vehicle and equipment maintenance indoors when possible to eliminate storm water exposure to pollutants from these activities. Due to the size and nature of aircraft and some associated equipment, maintenance cannot always be conducted indoors. When feasible, Co-permittees use drip pans, absorbents or other means of spill prevention, when conducting maintenance outdoors to minimize potential for oil and grease to be released onto paved surfaces. This minimizes storm water exposure to potential pollutants. Fluids are drained from vehicles and equipment that are no longer in service and need to be stored for a short time before being moved off-site for disposal or recycling. Many locations at PDX have catch basins with an invert pipe designed to capture oil and grease. This helps to minimize oil and grease that enters the storm water system. Each Co-permittee is responsible for identifying and inspecting catch basins in industrial activity areas on their leaseholds. Catch basins located in industrial areas are inspected monthly by the responsible Co-permittee. Some Co-permittees are responsible for the cleaning and maintenance of the catch basins on their leaseholds. Responsibilities are outlined in each tenants individual lease agreement. Structural/Treatment BMPs include oil-water separators, quiescent water quality improvement ponds, water quality manholes, water quality treatment vaults and vegetated swales. Parking lots are not a regulated activity under the 1200-COLS permit; however, vegetated storm water swales are utilized by the Port for storm water treatment of the discharge from the PDX Employee Parking Lot which drains to outfalls 8 and 9. Quiescent water quality improvement ponds at the downstream ends of Drainage Areas 2, 4 and 6 provide additional storm water treatment and containment of and potential spills. Each quiescent pond is equipped with a valve which is normally in the open position. Storm Portland International Airport COLS DEQ File No

30 water from the drainage area enters the pond and is detained for hours or days, based on flow, before discharging to the Columbia Slough. Each pond has absorbent and hard booms that remove oil and prevent other floatable materials from leaving the pond. If a serious spill occurs in the drainage area the spilled material would be recovered from the pond. The six drainage areas which do not have quiescent ponds have regularly maintained absorbent booms located just upstream of the outfall, or at the outfall. The preference is given to a location upstream of the outfall, but not all areas are conducive to this approach. Therefore, in some drainage areas the boom is placed at the outfall. The fuel island at the PDX Maintenance Facility is partially covered. Storm water from this area is routed through strip drains to an oil-water separator before being discharged to the storm water system. This minimizes the discharge of oil and grease in storm water due to leaks and spills during operation of the fuel island. In addition, Port Aviation Environmental personnel conduct monthly inspections of the fuel island and oil-water separator. Catch basin filters are installed in all catch basins where industrial activity occurs at the PDX Maintenance Facility. Catch basin filters are replaced annually by PDX Maintenance staff, or more frequently as needed. Oil-water separator inspections and catch basin maintenance are documented and kept on file in Aviation Environmental. The Port conducts cleaning of their mowers, sweeper trucks, Neal seal machine, and other equipment in the wash bay area of the PDX Maintenance Facility. This area is covered and drains to an oil-water separator connected to the sanitary sewer system. This eliminates the potential discharge of oil and grease to the storm water drainage system during cleaning of this equipment. In addition, the catch basins outside the vehicle wash rack discharge to an oil-water separator and then to the sanitary sewer system. These sanitary catch basins are used to discharge non-hazardous waste, such as latex paint rinse water and rinse water from the Tack Machine, and wash water created in the daily maintenance activities. The 2000-gallon AST at the Port fire station is equipped with double walls to serve as a secondary containment structure. The oil-water separator collects runoff from the fueling pad and surrounding area minimizing the discharge of oil and grease in storm water due to leaks and spills. In addition, the two JP-4 fuel ASTs at the fire training facility (one of which is owned and operated by the ORANG), are surrounded by a concrete secondary containment structure. A sump inside the containment structure allows any spilled fuel and storm water to drain into the adjacent oil-water separator to minimize discharge of oil and grease. The water from the separator is disposed of to the sanitary system under batch discharge requests authorized by the City of Portland. The PFFC fuel station located adjacent to the Ground Run-up Enclosure, west of Taxiway J is fully covered and drains to an oil- water separator and then to a containment tank. The PFFC fuel station located on the east end of Concourse E is not covered, but an oil-water separator is installed on-site to minimize the discharge of oil and grease in storm water due to leaks and spills. PFFC owns both fuel islands and they are operated by ASIG. PFFC also owns two regular unleaded gasoline fuel stations for ground service equipment, which are operated by ASIG. Both of these fuel stations drain through an oil-water separator to the storm system. Portland International Airport COLS DEQ File No

31 Co-permittees are required to have a spill response plan per requirements in the 1200-COLS permit. Waste Chemicals and Material Disposal Waste chemicals are produced by the Port and its Co-permittees from industrial activities conducted at PDX. Each entity is responsible for managing its own waste. Used motor oils, hydraulic fluid, solvents, and paints typify the majority of waste chemicals generated at PDX. Currently, waste chemicals generated by the Port or its Co-permittees are recycled or disposed off-site by a licensed contractor. Prior to disposal or recycling, these materials are typically stored in dumpsters or labeled 55-gallon drums or other appropriate labeled containers. All Port-operated waste bins and dumpsters are covered to prevent exposure of the waste to storm water. Port hazardous and special wastes are stored inside the Port s Hazardous Material Building. The Port maintains a double-walled, 500-gallon AST at its vehicle maintenance shop for the storage of used oil. Sweeper debris is stored in a designated containment area at the PDX Maintenance Facility (PMF) which drains to the sanitary system. The sweeper debris is re-profiled as necessary for permitted disposal at a licensed landfill. The Aviation Environmental and Safety Department staff maintains records of the sweeper debris profiles and disposal. Catch basin filters are utilized by the Port at the PMF. These are maintained by Port Maintenance and are changed out annually or more frequently if needed, and disposed of as non-hazardous waste. Erosion and Sediment Control Several drainage basins have vegetated drainage ditches and swales that convey storm water. The vegetation can provide a removal mechanism for storm water pollutants, including TSS. The three detention ponds also provide control of sediment discharges. Bioswales are used at the PDX Employee Parking Lot, grassy swales are used on the west side of the overpass on Airport Way, and rocky swales are used on the site surrounding the Deicing Treatment Plant. A sediment fence has been installed on the south side of the compost pile located at the PMF because the south side of the pile is adjacent to McBride Slough. This prevents any compost material from leaving the site and entering the storm water system. The remaining area to the north and west of the mulch pile is pervious and does not have any storm drains in the vicinity. All Port construction contractors are required to comply with the Port s DEQ-issued NPDES General Construction Storm Water Permit 1200-CA or to obtain and comply with their own 1200-C permit. The Port implements construction specifications for Required Environmental Practices for Construction in order to minimize environmental risk at PDX and the Port s General Aviation Airports. Contractors are required to follow the construction specifications pertaining to the Port s permit conditions. The Port prepares a project-specific erosion control plan and the contractor supplies some additional information for the plan. The Port s engineering and environmental staff review the plans. In addition, all construction projects that require a City of Portland building permit of any kind are done in compliance with the most current edition of the City of Portland s Erosion Control Manual. Tenant construction contractors must also comply with the various storm water Portland International Airport COLS DEQ File No

32 regulations by obtaining their own 1200-C permits from DEQ and building permits from the City. Any construction dewatering that occurs on PDX property is required to comply with the Port s NPDES Waste Water Permit for discharge of treated excavation waste water and the 1200-CA for uncontaminated groundwater. Port construction contractors are required to follow dewatering guidelines in the contract specifications and tenant construction contractors are required to comply with a given set of permit criteria which must be met prior to any construction discharges to either the land or storm water system. Both Port and Tenant construction contractors must submit a dewatering plan which is reviewed by Port engineering and environmental staff. All Port construction inspectors are trained annually on appropriate construction dewatering and erosion control measures to assist in the enforcement of mandatory erosion control measures. Dust and Debris Control To minimize the presence and buildup of debris on impervious areas within the security fence, the Port and its tenants inspect outdoor areas on a daily basis. Foreign Object Debris (FOD) can damage aircraft and is therefore monitored and removed. The prevention and removal of FOD greatly reduces the amount of debris that reaches catch basins on PDX property. As part of a FOD prevention program, the Port operates sweeper trucks a minimum of 8 hours per day. Depending on the function of the impervious surface, the area may be swept as many as three times per week. Parking structures and main parking lot travel areas are swept every two weeks. Construction contractors are required to provide a sweeper for all projects to remove any FOD resulting from the construction activity. These sweepers are operated during construction hours. Maintenance crews are utilized for trash and debris collection on both landside and airside areas every two weeks. These crews collect litter and debris along Marine Drive, inside the airport security fence, and at various other locations. Debris control is also provided by the booms in each drainage area and detention ponds in Drainage Areas 2, 4, 6, and 7. Drainage Areas 2, 4, and 6 have booms located in the quiescent ponds. Additional debris control in drainage areas 2 and 6 are provided by the detention ponds. In Drainage Area 7, a boom and trash gate is located at the outfall on McBride to minimize discharge of debris. The booms are replaced on a regular basis. Drainage Area 6 has a trash rack located in front of the outfall at Pump Station 6. Debris control in Drainage Area 7 is also provided by catch basins and catch basin filters in place at the maintenance facility. Covering of Potential Contaminant Sources Covering materials and source areas prevents exposure of uncontaminated storm water to potential pollutants. However, due to the nature and size of aircraft and FAA regulations, covering of facilities associated with aircraft is not always feasible. Portland International Airport COLS DEQ File No

33 The jet fuel island, located on the south side of Taxiway F next to the GRE, provides jet fuel to trucks which fuel aircraft parked at the nearby areas. This fuel island, which is operated by ASIG, is covered to prevent the exposure of storm water to fuel transfer operations. The Port operates a fueling area at the PMF compound. The pump islands and most of the surrounding concrete pads are covered. All Port vehicle maintenance is conducted indoors with the exception of maintenance on large mowers that cannot physically fit inside the maintenance bay. Horizon, Ameriflight, Bonneville Power Administration and SkyWest are the only Copermittees with facilities to conduct aircraft maintenance indoors. All airline Copermittees or their respective contractors conduct routine maintenance of their aircraft at the gate or on the ramp areas. Delta, United, Horizon, SkyWest, Bonneville Power Administration, Aircraft Terminal Services, American Airlines, Evergreen Aviation and a number of other Co-permittees and tenants have indoor equipment and vehicle maintenance facilities. The significant materials associated with the maintenance activities are stored inside these facilities. Co-permittees utilize cabinets, or other types of containment for the storage of significant materials outdoors. In the gate areas, cabinets are used to store new oil and other maintenance supplies. Some tenants utilize cabinets for the storage of used oil. During construction projects, if contaminated soil is encountered it is placed on an impervious surface, a berm is placed around the material and it is covered with plastic to prevent contact with storm water prior to disposal. Housekeeping Good housekeeping can reduce pollutants at the source to prevent the pollution of storm water runoff discharged from the site. Port staff performs monthly inspections of outdoor areas at the PDX including: Maintenance Facility compound and fuel island, vehicle wash rack, and fuel storage area, the Fire Training Facility, the Central Utility Plant, and the Fire Station. These areas are continually being monitored by Port staff, and every effort is made to keep all Port facilities clean. Co-permittees have established routine inspection programs for their industrial activities. PFFC and ASIG perform daily inspections of the fuel tank farm and fuel islands. Other Co-permittees typically inspect their fuel islands, outdoor storage areas, and maintenance areas on a daily or weekly basis. The Port operates sweeper trucks a minimum of 8 hours per day. Depending on the function of the impervious surface, the area may be swept as many as 3 times per week. Parking structures and main parking lot travel areas are swept every 2 weeks. Standard Parking, the Port s contracted parking management company, conducts daily inspections of the storm water drains during the rainy season and conduct weekly debris pick-up in all Port parking lots. If a problem with a drain is discovered, Standard will remove the debris on top of the drain, or have Port maintenance clean the drain out completely. Port maintenance removes leaves and debris from the storm system in the Economy parking lots every year. Portland International Airport COLS DEQ File No

34 Co-permittees conducting maintenance activities outdoors have spill equipment on hand and promptly clean up spills from maintenance activities. B. Spill Prevention and Response Procedures (Spill Plan) Schedule A.7.(c).ii requires that methods to prevent spills along with clean-up and notification procedures shall be included in the SWPCP. An Emergency Spill Response Plan has been developed by the Port for spills at PDX. The plan sets forth roles and responsibilities of emergency responders and procedures related to the release of oil or hazardous materials at PDX. The main objective of the plan is to identify emergency response procedures designed to minimize hazards to human health and the environment in the event that an emergency should occur. For small spills which do not require emergency response, procedures consist of containment, absorption, clean up and disposal. Spill cleanup kits are available and deployed throughout airport facilities and on fuel tankers. Small spills are addressed immediately. The following two documents should be referred to for more information on Port spill prevention and response procedures: Spill Prevention Control and Countermeasure Plan (PDX SPCC Plan) and Portland International Airport Spill Response Procedures. These documents are available from the Port of Portland Aviation Environmental Department. Co-permittees are each required to prepare a spill plan applicable to their operations. The spill plan must include methods to prevent spills along with clean-up and regulatory agency and Port notification procedures. These methods and procedures shall be made available to appropriate personnel. The required clean-up material shall be on-site or readily available. Spill prevention plans required by other regulations may be substituted for this provision providing that storm water management concerns are adequately addressed. In addition, Co-permittees who own or operate underground or aboveground petroleum storage tanks may be required to prepare a Spill Prevention Control and Countermeasure (SPCC) plan under the federal Oil Pollution Prevention Regulation (40 Code of Federal Regulations Part 112) to address spill prevention to navigable waters of the United States. It is the responsibility of Co-permittees who own and operate storage tanks to assess their operations and determine if an SPCC plan is required. More information may be obtained at the U.S. Environmental Protection Agency (EPA) website Regulations allow the spill plan and SPCC plan to be combined into a single document. C. Preventative Maintenance Schedule A.7.(c).iii requires implementation of a preventative maintenance program. Routine preventative maintenance by the Port and Co-permittees has an important role in reducing the discharge of pollutants in storm water from PDX. The preventative maintenance program ensures the proper operation of all storm water BMPs. The key elements of the preventative maintenance program include: Monthly inspections of areas where potential spills of significant materials or industrial activities that could impact storm water runoff occur. Monthly inspections of storm water control measures, structures, catch basins, and treatment facilities. Portland International Airport COLS DEQ File No

35 Cleaning, maintenance and/or repair of all materials handling and storage areas as well as storm water control measures, structures, catch basins, and treatment facilities in areas which drain industrial activity areas. The frequency of this program will depend on whether the benchmarks are being met within that drainage area. Cleaning, maintenance and/or repair of septic systems. The DEQ guidelines for cleaning and maintenance of septic systems should be followed to ensure the proper operation of the system. Preventative maintenance on all Port vehicles and industrial equipment. Regular pick-up of and disposal of landfill waste and recyclable materials. Immediate follow up to correct problems encountered during inspections and complete documentation of the corrective measures 1. Inspection of Areas with Significant Materials and Industrial Activities Port staff performs and documents monthly inspections of Port industrial areas (See Appendix C PDX Storm Water Inspection Forms and Procedures). These include the PMF compound, Central Utility Plant, Fire Training Facility, Fire Station, and Deicing Treatment Plant. The general condition of each area is inspected as well as the condition of any storm water controls such as catch basin filters, oil-water separators, AST tank integrity, and secondary containment. All areas used for fueling, washing or other industrial activities are inspected, which includes the fuel system pumps and tanks. Other areas that are inspected include but are not limited to ASTs, USTs, and solid waste containers. Runways and taxiways are inspected by the Airfield Supervisor three times each 24-hour period to identify and remove any debris. These inspections are not documented as part of the industrial activities inspections since these areas are not regulated. Non-regulated areas such as parking lots, roadways, and grassy areas are not required to be inspected; however, Standard Parking inspects the Port s public parking lots daily. These areas are also indirectly inspected for pollutants via the monthly outfall inspections. Co-permittees are required to establish routine inspection programs for their industrial activities. PFFC and ASIG perform daily inspections of the fuel tank farm and fuel islands. Other Co-permittees typically inspect their fuel islands, outdoor storage areas, and maintenance areas on a daily or weekly basis. Each Co-permittee is responsible for their leasehold area, equipment, storage areas, storage tanks, and any other areas. Co-permittees are required to do the following: Follow procedures for and document monthly inspections of terminal ramps and aircraft maintenance areas. Identify and correct any spills or releases of petroleum products or other potential storm water contaminants. Perform and document regular inspections of all equipment and vehicles to minimize leaks of oil and grease, hydraulic fluids, and fuel and perform preventative maintenance Portland International Airport COLS DEQ File No

36 where applicable. Inspections must be documented and records maintained for a minimum of three years. Follow procedures for and document monthly inspections of all regulated industrial activities including storage tanks, fueling areas, chemical storage areas, and materials handling areas (loading docks) in accordance with schedule B Inspection of Storm Water Controls Port maintenance and environmental staff perform regular inspections of storm water control structures, catch basins, and treatment facilities at PDX as described below. Catch Basins: There are approximately 3,000 catch basins, inlets and manholes at PDX. All catch basins and storm water lines at PDX are cleaned and inspected on a 5 year rotating schedule. Catch basins in Port industrial areas are inspected on a monthly basis and are cleaned out annually. Ponds: The three quiescent ponds at the downstream end of Drainage areas 2, 4, and 6 are inspected monthly. The ponds are on a three-year rotating schedule for cleaning. Swales: The swales are periodically inspected and maintained by PDX Maintenance. Outfalls: The Port has developed an illicit discharge detection and removal program to comply with the MS4 permit which involves inspections of PDX s nine major outfalls, during the wet and dry season which is discussed in more detail in Section F. Port environmental staff visually inspects PDX s nine primary outfalls monthly and documents observations of odor, discoloration, turbidity, floating solids and petroleum sheen. Oil-water Separators: Port Environmental staff conducts monthly inspections of Port oilwater separators which drain industrial areas. Port oil-water separators which drain industrial areas are on an annual cleaning program. Oil-water separators that drain parking lots and the parking garage are inspected annually and cleaned on an as-needed basis. Absorbent Booms, Catch Basin Filters, and Hard Booms: The Port inspects and maintains absorbent and hard booms in its three quiescent ponds, and outfalls on a monthly basis. Catch basin filters at the PDX Maintenance Facility are also inspected on a monthly basis. Co-permittees are required to perform and document monthly inspections of storm water controls on their leaseholds. 3. Cleaning, Maintenance and/or Repair Catch Basins. Catch basins that drain industrial areas are cleaned on an annual basis by the Port. Catch basins that do not drain industrial areas are cleaned by the Port on an average of once every three to five years at PDX. The structural condition of the catch basin is recorded and any needed repairs are conducted in a timely manner. Materials removed from catch basins are stored in a cubic yard drop box in the solids containment area at the PMF.

Employee Education Each Co-permittee is responsible for the training of its employees. The 1200-COLS permit requires each Co-permittee to develop an employee orientation and education program that informs personnel of the components and goals of the SWPCP. The Port provides training to all of its employees within thirty days of the time of initial hire. Port employees who work in areas where storm water is exposed to industrial activities are given annual training. The Port s training program addresses best management practices and spill prevention and response procedures. The training program also provides training to employees on documentation requirements, how to complete inspection forms, what to look for during an inspection, and the appropriate follow up to storm water issues. Co-permittees are required to provide a similar level and frequency of training for their employees. Storm water markers have been applied to many of the storm drain inlets at PDX. Storm drain labels help to raise PDX s community awareness with regards to industrial activities and the storm water drainage system. Posted signs and storm water inlet markers in many areas at PDX also help to increase employees storm water awareness. Each Co-permittee is responsible for (1) developing and implementing storm water awareness, and spill prevention training of their staff; and (2) maintaining documentation that the training has been performed. Portland International Airport COLS DEQ File No

39 E. Record Keeping and Internal Reporting Procedures Port staff document and maintain the following information at the PDX environmental office, Port Fire Department, or on the maintenance database for a minimum of three years: A copy of the SWPCP and any revisions, corrective action reports, and monthly inspection reports. Port incidents of spills or leaks of materials or other concern which may impact storm water quality, along with corrective actions, surface water discharge. Inspection, maintenance, repair and education activities Co-permittees are responsible for maintaining records at their respective facilities for a minimum of three years. In addition analytical data is maintained in hard copies and in a water quality database, which is used to track water quality monitoring and discharges. F. Non-stormwater Discharges Under the Port s MS4 permit (see section XII MS4 Permit Activities) the Port is required to have an illicit detection and elimination program for all non-stormwater discharges not authorized by one of the Port s NPDES permits. The Port will eliminate any non-stormwater discharges not authorized if detected during routine inspections or upon discovering evidence of a discharge. Portland International Airport COLS DEQ File No

40 XI. Monitoring Locations In accordance with Schedule A and B of the 1200-COLS permit, storm water discharged from PDX must be visually monitored and sampled for water quality analysis. The sample parameters and frequency are summarized in Table 6. The Port samples eight of the nine major drainage basins at PDX (see Figure 2) according to the criteria specified in the COLS permit. The storm water runoff from PDX industrial activities is represented by the analysis of samples collected at ten designated outfalls. Samples are not collected from Outfall 9 because this area does not drain industrial activities covered by the 1200-COLS permit. Samples are not collected from the Columbia River outfall because this outfall is regulated under permit # All nine of PDX s major outfalls to the Columbia Slough are visually monitored once each month for flow, water clarity, water color, odor, foam, floating solids, and oil and grease sheen. Grab or composite sampling of the eight basins are conducted at ten designated monitoring points (see Figure 2 and Table 5) four times per permit reporting year (July 1 June 30) within 12 hours of storm water discharge. Two samples are collected prior to December 31, at least 14 days apart and two samples are taken after December 31, also at least 14 days apart after a previous sampling event. Both sets of samples are analyzed for the constituents listed in Schedule B of the general permit and presented in Table 6. Table 6 also lists the benchmarks for these constituents. The storm water monitoring period is July 1 through June 30. The Port tabulates and submits the data to the DEQ s Northwest Regional Office by July 31 of each year. All the sampling data and annual reports are retained by the Port for a minimum of 5 years. Each Co-permittee is responsible for retaining the records for their inspections and BMP implementation.

43 XII. Municipal Separate Storm Sewer System (MS4) Permit Activities Storm water at PDX discharges to the Port s municipal separate storm sewer system (MS4). The Port is a Co-permittee with the City of Portland on the NPDES MS4 Permit Number (MS4 Permit), issued in The MS4 Permit requires the Port to develop and implement a Storm Water Management Plan (SWMP). The primary component of the Port of Portland SWMP is a program of Best Management Practices (BMPs) to minimize pollutant discharge into surface waters to the maximum extent practicable. The BMP components outlined in this SWPCP also meet the requirements of the Port s MS4 Permit with respect to PDX. Although not required by the PDX 1200-COLS permit, the MS4 Permit requires the Port to implement illicit discharge detection and elimination program and a program to minimize pollutants related to pesticide and fertilizer activities for all Port facilities, including PDX. These two additional MS4 Permit requirements are implemented as outlined by the Port s Illicit Discharge Detection and Elimination Procedure Manual and the Program Description for Pesticide and Fertilizer Use on Port Property.
