Best Management Practices This project implements Best Management Practices (BMPs) to address the Pollutants of Concern that may potentially be generated from the use of the project site. These BMPs have been selected and implemented to comply with the Section 3.5 of the WQMP and consist of Site Design, Source Control and, if/where necessary, Treatment Control BMPs as described herein. V.1 SITE DESIGN AND TREATMENT CONTROL BMPS Local Jurisdiction Requires On-Site Retention of Urban Runoff: Yes The project will be required to retain urban runoff onsite in conformance with local ordinance (See Table 6, Permittees Requiring Onsite Retention of Stormwater, of the Whitewater River Region WQMP). Section V.1 does not need to be completed. No Section V.1 must be completed. This section of the Project-Specific WQMP documents the Site Design BMPs and, if/where necessary the Treatment Control BMPs that will be implemented on the Project to meet the requirements within Section 3.5.1 of the WQMP. Section 3.5.1, includes requirements to implement Site Design Concepts and BMPs, and includes requirements to address the project’s Pollutants of Concern with BMPs. Further sub-section 3.5.1.1 specifically requires that the projects Pollutants of Concern be addressed with Site Design BMPs to the extent feasible. This project incorporates Site Design BMPs to fully address the Pollutants of Concern where and to the extent feasible. If and where it has been acceptably demonstrated to the Permittee that it is infeasible to fully meet this requirement with Site Design BMPs, this section includes a description of the conventional Treatment Control BMPs that will be substituted to meet the same requirements. In addressing pollutants of concern, BMPs are selected using Table 2 below. Whitewater River Region WQMP Palm Springs Apron Reconstruction DATE 1-9 Table 2.

Whitewater River Region WQMP Palm Springs Apron Reconstruction DATE 1-10 V.1.A SITE DESIGN BMPS This section documents the Site Design BMPs that will be implemented on this project to comply with the requirements in Section 3.5.1 of the WQMP. x Table 3 herein documents the implementation of the Site Design Concepts described in sub-sections 3.5.1.3 and 3.5.1.4. x Table 4 herein documents the extent to which this project has implemented the goals described in sub-section 3.5.1.1. Whitewater River Region WQMP Palm Springs Apron Reconstruction DATE 1-11 Table 3. Implementation of Site Design Concepts Included Brief Reason for BMPs Indicated as No or N/A Design Concept Technique Specific BMP Yes No N/A Site Design Concept 1 Minimize Urban Runoff, Minimize Impervious Footprint, and Conserve Natural Areas (See WQMP Section 3.5.1.3) Conserve natural areas by concentrating or cluster development on the lease environmentally sensitive portions of a site while leaving the remaining land in a natural, undisturbed condition. There are no sensitive portions of the project. The site is fully developed. Conserve natural areas by incorporating the goals of the Multi-Species Habitat Conservation Plan or other natural resource plans. The site has not increased the pavement footprint Preserve natural drainage features and natural depressional storage areas on the site. Unpaved taxiway islands and natural channels are preserved for this project Maximize canopy interception and water conservation by preserving existing native trees and shrubs, and planting additional native or drought tolerant trees and large shrubs. No grubbing/vegetation removal is occurring for this project Use natural drainage systems. All existing natural drainage systems are protected in place. Increase the building floor area ratio (i.e., number of stories above or below ground). No structure work Construct streets, sidewalks and parking lot aisles to minimum widths necessary, provided that public safety and a walkable environment for pedestrians is not compromised. Taxiways are constructed to design minimums. Reduce widths of streets where off-street parking is available. Does not apply to airfields. Design driveways with shared access, flared (single lane at street), or wheel strips (paving only under the tires). Does not apply to airfields. Minimize the use of impervious surfaces, such as decorative concrete, in the landscape design. Does not apply to airfields. Other comparable and equally effective Site Design BMP (or BMPs) as approved by the Permittee (Note: Additional narrative required to describe BMP and how it addresses site design concept). Whitewater River Region WQMP Palm Springs Apron Reconstruction DATE 1-12 Table 3. Site Design BMPs (continued) Included Brief Reason for Each BMP Indicated as No or N/A Design Concept Technique Specific BMP Yes No N/A Site Design Concept 2 Minimize Directly Connected Impervious Area (See WQMP Section 3.5.1.4) Residential and commercial sites must be designed to contain and infiltrate roof runoff, or direct roof runoff to vegetative swales or buffer areas. Most apron drainage flows through natural swales. Ultimately, stormwater flows end at retention basin. Drain impervious sidewalks, walkways, trails, and patios into adjacent landscaping. Most apron drainage flows through natural swales. Ultimately, stormwater flows end at retention basin. Incorporate landscaped buffer areas between sidewalks and streets. No streets in this project. Uncovered temporary or guest parking on residential lots paved with a permeable surface, or designed to drain into landscaping. No guest/residential parking in this project. Rural swale system: street sheet flows to vegetated swale or gravel shoulder, curbs used at street corners, and culverts used under driveways and street crossings. Most apron drainage flows through natural swales. Ultimately, stormwater flows end at retention basin. Urban curb/swale system: street slopes to curb; periodic swale inlets drain to vegetated swale or biofilter. Sheet flows from apron directly enter natural swales, no curbs installed. Dual drainage system: first flush captured in street catch basins and discharged to adjacent vegetated swale or gravel shoulder; high flows connect directly to MS4s. No collected curb flows Maximize the permeable area by constructing walkways, trails, patios, overflow parking, alleys, driveways, low-traffic streets, and other low- traffic areas with open-jointed paving materials or permeable surfaces such as pervious concrete, porous asphalt, unit pavers, and granular materials. No low-traffic areas Use vegetated drainage swales in lieu of underground piping or imperviously lined swales. Natural swales have been protected in place Incorporate parking area landscaping into the drainage design. No parking areas Where soil conditions are suitable, use perforated pipe or gravel filtration pits for low flow infiltration. No storm drain pipe being constructed Whitewater River Region WQMP Palm Springs Apron Reconstruction DATE 1-13 Included Brief Reason for Each BMP Indicated as No or N/A Design Concept Technique Specific BMP Yes No N/A Construct onsite infiltration BMPs such as dry wells, infiltration trenches, and infiltration basins consistent with vector control objectives. Open air infiltration basin draws down in less than 24 hours, no other infiltration BMPs required Construct onsite ponding areas or detention facilities to increase opportunities for infiltration consistent with vector control objectives. Island areas between taxiway and apron are sumped to allow for capture and infiltration of runoff. Whitewater River Region WQMP Palm Springs Apron Reconstruction DATE 1-14 Table 3. Site Design BMPs (continued) Included Brief Reason for Each BMP Indicated as No or N/A Design Concept Technique Specific BMP Yes No N/A Site Design Concept 2 (cont’d) Minimize Directly Connected Impervious Area (See WQMP Section 3.5.1.4) Direct roof runoff into cisterns or rain barrels for reuse. No building/architectural construction is occurring. Additionally, existing roof drains are hard-piped to grade, but they eventually drain to infiltration basin. Use vegetated drainage swales in lieu of underground piping or imperviously lined swales. All natural earth islands between taxiway and apron are being protected in place and utilized for drainage. Incorporate tree well filters, flow-through planters, and/or bioretention areas into landscaping and drainage plans. No landscaping design or trees in project Other comparable and equally effective Site Design BMP (or BMPs) as approved by the Permittee (Note: Additional narrative required describing BMP and how it addresses site design concept). Whitewater River Region WQMP Palm Springs Apron Reconstruction DATE 1-15 Project Site Design BMPs: The majority of the Apron area sheet flows to native yet maintained islands between the apron and Taxiway ‘W’. The natural channel flowlines provide an increased time of concentration and increased infiltration rate, when compared to direct piping and full pavement. Flows ultimately collect into a master storm drain system that passes through and existing oil-grit separator. The separator has a maximum oil storage capacity of 850 gallons, and half-full sediment capacity of 95 cubic-feet. The system is maintained yearly with full removal of oil and sediments. Roughly 600 feet downstream of the separator, the airport has installed a 244,000 cubic-foot stormwater retention basin. There is no low-flow outlet, meaning the entire 4 foot storage depth is infiltrated. Alternative Project Site Design BMPs: Industrial Permit Sampling (# 7 33I001282) requires the Airport to sample water quality in any qualifying discharge rain event. This is a method to verify the effectiveness of the Design and Operational BMPs Whitewater River Region WQMP Palm Springs Apron Reconstruction DATE 1-16 Table 4.

Whitewater River Region WQMP Palm Springs Apron Reconstruction DATE 1-22 Following is a brief narrative describing how each included Source Control BMP will be implemented. -Education for property owners will be provided with standard City, County, and CASQA flyers in Appendix D. Also included is an excerpt of the Airports Desk Reference document for Water Quality on airports and CASQA post-construction BMPs indicating proper maintenance techniques for the in-place BMPs. -Activities on this project are limited to SIC 4581 - Airports, Flying Fields, and Airport Terminal Services Establishments primarily engaged in operating and maintaining airports and flying fields; in servicing, repairing (except on a factory basis), maintaining, and storing aircraft; and in furnishing coordinated handling services for airfreight or passengers at airports. This industry also includes private establishments primarily engaged in air traffic control operations. Government air traffic control operations are classified in Public Administration, Industry 9621. These activities include: Aircraft cleaning and janitorial service, Aircraft servicing and repairing (except on a factory basis), Aircraft storage at airports, Aircraft upholstery repair, Airfreight handling at airports, Airport hangar rental, Airport leasing (if operating airport), Airport terminal services, Airports, Hangar operation. -Common area litter control is maintained through several programs. First and foremost, Advisory Circular 150/5200-18C Airport Safety Inspection mandates an Airport Foreign Object Debris (FOD) Management plan, per AC 150/5210-24, that keeps any and all trash, rocks, sand, etc. from posing a threat to aircraft via ingestion and/or blowing. A rigorous program of immediate removal of any trash is the cornerstone of this system and a requirement for airport certification by the FAA. The Safety Inspection and the FOD plan ensure minimal large contaminates effect the site. Trash cans underneath the terminal exist for use by airport staff. A large industrial trash bin exists north of the Bono concourse next to the Terminal. http://www.faa.gov/regulations_policies/advisory_circulars/index.cfm/go/document.information/documen tID/23179 http://www.faa.gov/regulations_policies/advisory_circulars/index.cfm/go/document.information/documen tID/391902 -A street sweeping program is part of the FOD management plan and is required on a quarterly basis.

Whyisstormwaterrunoff aproblem? Theeffectsofpollution Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater from naturally soaking into the ground. Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing, and providing drinking water. Polluted stormwater runoff can have many adverse effects on plants, fish, animals, and people. Sediment can cloud the water and make it difficult or impossible for aquatic plants to grow. Sediment also can .destroy aquatic habitats Excess nutrients can cause algae blooms. When algae die, they sink to the bottom and decompose in a process that removes oxygen from the water. Fish and other aquatic organisms can’t exist in water with low dissolved oxygen levels. Bacteria and other pathogens can wash into swimming areas and create health hazards, often making beach closures necessary. Debris—plastic bags, six-pack rings, bottles, and cigarette butts—washed into waterbodies can choke, suffocate, or disable aquatic life like ducks, fish, turtles, and birds. Household hazardous wastes like insecticides, pesticides, paint, solvents, used motor oil, and other auto fluids can poison aquatic life. Land animals and people can become sick or die from eating diseased fish and shellfish or ingesting polluted water. Polluted stormwater often affects drinking water sources. This, in turn, can affect human health and increase drinking water treatment costs.AftertheStormEPA 833-B-03-002January 2003For more information contact:or visitwww.epa.gov/npdes/stormwaterwww.epa.gov/npsACitizen’sGuidetoUnderstandingStormwaterWHEN IT RAINSIT DRAINSWHEN IT RAINSIT DRAINSInternet Address (URL) HTTP://www.epa.govRecycled/Recyclable Printed With VegetableOil Based Inks on 100% Postconsumer,Process Chlorine Free Recycled Paper●● Auto care Washing your car and degreasing auto parts at home can send detergents and other contaminants through the storm sewer system. Dumping automotive fluids into storm drains has the same result as dumping the materials directly into a waterbody. Pet waste Pet waste can be a major source of bacteria and excess nutrients in local waters. When walking your pet, remember to pick up the waste and dispose of it properly. Flushing pet waste is the best disposal method. Leaving pet waste on the ground increases public health risks by allowing harmful bacteria and nutrients to wash into the storm drain and eventually into local waterbodies. Septic systems Leaking and poorly maintained septic systems release nutrients and pathogens (bacteria and viruses) that can be picked up by stormwater and discharged into nearby waterbodies. Pathogens can cause public health problems and environmental concerns. Lawn care Excess fertilizers and pesticides applied to lawns and gardens wash off and pollute streams. In addition, yard clippings and leaves can wash into storm drains and contribute nutrients and organic matter to streams. Education is essential to changing people's behavior. Signs and markers near storm drains warn residents that pollutants entering the drains will be carried untreated into a local waterbody.Recycle or properly dispose of household products that contain chemicals, such as insecticides, pesticides, paint, solvents, and used motor oil and other auto fluids. Don’t pour them onto the ground or into storm drains. Use a commercial car wash that treats or recycles its wastewater, or wash your car on your yard so the water infiltrates into the ground. Repair leaks and dispose of used auto fluids and batteries at designated drop-off or recycling locations. Don’t overwater your lawn. Consider using a soaker hose instead of a sprinkler. Use pesticides and fertilizers sparingly. When use is necessary, use these chemicals in the recommended amounts. Use organic mulch or safer pest control methods whenever possible. Compost or mulch yard waste. Don’t leave it in the street or sweep it into storm drains or streams. Cover piles of dirt or mulch being used in landscaping projects. Inspect your system every 3 years and pump your tank as necessary (every 3 to 5 years). Don't dispose of household hazardous waste in sinks or toilets. Dirt, oil, and debris that collect in parking lots and paved areas can be washed into the storm sewer system and eventually enter local waterbodies. Sweep up litter and debris from sidewalks, driveways and parking lots, especially around storm drains. Cover grease storage and dumpsters and keep them clean to avoid leaks. Report any chemical spill to the local hazardous waste cleanup team. They’ll know the best way to keep spills from harming the environment. Erosion controls that aren’t maintained can cause excessive amounts of sediment and debris to be carried into the stormwater system. Construction vehicles can leak fuel, oil, and other harmful fluids that can be picked up by stormwater and deposited into local waterbodies. Divert stormwater away from disturbed or exposed areas of the construction site. Install silt fences, vehicle mud removal areas, vegetative cover, and other sediment and erosion controls and properly maintain them, especially after rainstorms. Prevent soil erosion by minimizing disturbed areas during construction projects, and seed and mulch bare areas as soon as possible. Uncovered fueling stations allow spills to be washed into storm drains. Cars waiting to be repaired can leak fuel, oil, and other harmful fluids that can be picked up by stormwater. Clean up spills immediately and properly dispose of cleanup materials. Provide cover over fueling stations and design or retrofit facilities for spill containment. Properly maintain fleet vehicles to prevent oil, gas, and other discharges from being washed into local waterbodies. Install and maintain oil/water separators. Lack of vegetation on streambanks can lead to erosion. Overgrazed pastures can also contribute excessive amounts of sediment to local waterbodies. Excess fertilizers and pesticides can poison aquatic animals and lead to destructive algae blooms. Livestock in streams can contaminate waterways with bacteria, making them unsafe for human contact. Keep livestock away from streambanks and provide them a water source away from waterbodies. Store and apply manure away from waterbodies and in accordance with a nutrient management plan. Vegetate riparian areas along waterways. Rotate animal grazing to prevent soil erosion in fields. Apply fertilizers and pesticides according to label instructions to save money and minimize pollution. Permeable Pavement Rain Barrels Rain Gardens and Grassy Swales Vegetated Filter Strips —Traditional concrete and asphalt don’t allow water to soak into the ground. Instead these surfaces rely on storm drains to divert unwanted water. Permeable pavement systems allow rain and snowmelt to soak through, decreasing stormwater runoff. —You can collect rainwater from rooftops in mosquito- proof containers. The water can be used later on lawn or garden areas. —Specially designed areas planted with native plants can provide natural places for rainwater to collect and soak into the ground. Rain from rooftop areas or paved areas can be diverted into these areas rather than into storm drains. —Filter strips are areas of native grass or plants created along roadways or streams. They trap the pollutants stormwater picks up as it flows across driveways and streets. Residential landscaping Improperly managed logging operations can result in erosion and sedimentation. Conduct preharvest planning to prevent erosion and lower costs. Use logging methods and equipment that minimize soil disturbance. Plan and design skid trails, yard areas, and truck access roads to minimize stream crossings and avoid disturbing the forest floor. Construct stream crossings so that they minimize erosion and physical changes to streams. Expedite revegetation of cleared areas.

General. Many of the nation’s airports are located near waterways. This is because years ago when many airports were built, the cheapest, flattest, and most desirable lands suitable for airports were located near waterways. As a consequence, today’s airport activities may cause water quality impacts due to their proximity to waterways. In particular, construction activities or seasonal airport anti-icing/deicing activities are major concerns. Construction often causes sediment-laden runoff to enter waterways. Biological and chemical breakdown of deicing chemicals in airport runoff can cause severe dissolved oxygen demands on receiving waters. Operations or maintenance are other activities that may affect water quality. Airport-related water quality impacts can occur from both point and non-point sources at airports. If not properly controlled, the resultant water quality impacts may adversely affect animal, plant, or human populations. Therefore, FAA must evaluate project-related discharges, especially those having the potential to affect navigable waterways, municipal drinking water supplies, important sole-source aquifers, or protected groundwater supplies. b. Point sources. These are stormwater or other types of discharges from wastewater treatment plants, sanitary sewer systems, collection basins, or other water collection devices that flow through a conveyance (pipe) and discharge to a waterway. The states and the U.S. Environmental Protection Agency (EPA) issue National Pollutant Discharge Elimination System (NPDES) permits authorizing point source discharges into navigable waters of the United States under Section 402 of the Clean Water Act (CWA) (33 USC Section 1342). c. Non-point sources. These include stormwater runoff from runways, taxiways, aprons, outdoor storage areas, or construction areas that do not flow through conveyance systems. Federal permits are not necessary for non-point source discharges. d. Runoff pollutants. Point source and non-point source runoff may contain pollutants such as metals, oils, greases, hazardous materials, solids, hydrocarbons, pesticides, and herbicides. During dry weather, pollutants can accumulate on impermeable surfaces, but during storms they are washed into creeks, streams, lakes, or other waters causing potential water quality impacts. 2. APPLICABLE STATUTES AND IMPLEMENTING REGULATIONS. a. General. The principal statutory framework for considering water quality in Federal decisions is contained in the CWA. The following chart provides information on this and other important laws that protect surface water, groundwater, and aquatic systems: Chap. 20 Page 1 AIRPORTS DESK REFERENCE WATER QUALITY APPLICABLE STATUTES AND IMPLEMENTING REGULATIONS SUMMARY DESCRIPTION OVERSIGHT AGENCY Federal Water Pollution Control Act, as amended by the Clean Water Floodplains and Floodways Act of 1977 (CWA), 33 USC Chapter 26 Chapter 26 provides Congress’ mandate for developing comprehensive solutions to prevent, reduce, or remove pollution in waters of the United States. Section 401 of the Clean Water Act, 33 USC Section 1341, addresses state issuance of water quality certificates. Section 402 of the Clean Water Act, 33 USC Section 1342, addresses issuance of NDPES permits, while Section 404 of the Act, 33 USC Section 1344, focuses on dredge and fill permits in navigable waterways including wetlands. EPA or State or tribal water quality agencies CWA, Section 311, as amended by the Oil Pollution Act of 1990, 33 USC Section 1252 et seq. Requires owners or operators of above ground facilities storing oil or oil-based products to prepare spill response plans. EPA Safe Drinking Water Act, as amended (SDWA), 42 USC Section 300.f, et seq., also known as the Public Health Service Act Prohibits Federal agencies from funding actions that would contaminate a sole source aquifer or its recharge area. EPA 40 CFR Parts 142 and 149 Part 142 provides regulations addressing national primary drinking water supplies. Part 149 provides regulations addressing sole source aquifers. EPA Fish and Wildlife Coordination Act of 1980, 16 USC Section 661, et seq. Requires Federal agencies to consult with the Fish and Wildlife Service (FWS) for any action that would alter (impound, divert, drain, or control) a stream or other body of water. FWS 3. APPLICABILITY TO AIRPORT DEVELOPMENT PROJECTS. Building airport facilities may temporarily or permanently affect surface waters, groundwater, or drinking water supplies. As a result, when an airport sponsor requests FAA action to support an airport development project, FAA must evaluate the proposed project’s potential water quality impacts. Examples of airside airfield development projects that may cause water quality impacts include building or expanding terminals or hangars, building new or extended runways and taxiways, and installing navigational aids (NAVAIDS). Landside development that may alter water quality includes building or moving airport access roads, remote parking facilities, and rental car lots. Chap. 20 Page 2 AIRPORTS DESK REFERENCE WATER QUALITY 4. PERMITS, CERTIFICATIONS, AND APPROVALS. a. General. There are various water quality permits, certifications, and approvals that may be required to build and operate airport projects. The responsible FAA official must ensure the water quality chapter of the environmental document discloses any known problems in obtaining them. b. Water quality certificates (WQC). Airport sponsors needing the authorizations or permits noted in subsections 4.b(1) and (2) below must obtain a water quality certificate (WQC). The responsible FAA official must ensure the environmental document prepared for any action involving those authorizations or permits contains information about the status of, and any known problems in obtaining, the WQC. That information is an indicator of potential concerns about WQC issuance that may require further airport sponsor and/or FAA effort to mitigate adverse water quality effects to obtain the certificate. A WQC is required for: (1) An airport sponsor seeking an NPDES permit from the EPA or a state under Section 402 of the CWA; and (2) An airport sponsor seeking a permit under Section 404 of the CWA from the U.S. Army Corps of Engineers (Corps) or a state authorized to issue this permit for filling or dredging navigable waters, including jurisdictional wetlands (See Chapter 21 of this Desk Reference. c. NPDES permits. The environmental document prepared for any proposed airport action having a point source discharge to a navigable waterway or that would disturb at least 1 acre should include information on the status of the NPDES permit needed for that action, as described above in section 4.a of this chapter. It should also include any comments the permit-issuing agency provides. A copy of the NPDES permit is not needed for FAA’s approval of an airport layout plan or grant, but the environmental document prepared for the action should discuss any difficulties the issuing agency may have noted about permit issuance. An appendix to the environmental document should contain a copy of the letter from the permit agency or a copy of the permit, if the permit is issued before the document is completed. Note: 40 CFR Sections 122 through 124 provide more details on NPDES stormwater permits. See Chapter 6, of this Desk Reference (Construction Impacts) for a discussion on stormwater permits and construction activity. d. Agency opinions on safe drinking water supplies. An airport action has the potential to affect a public drinking water supply, a sole source aquifer, or a Comprehensive State Groundwater Protection Program (CSGWPP). To comply with Section 1424(e) of the Safe Drinking Water Act, the approving FAA official may not approve funds for any action if the EPA Administrator determines the action would contaminate a sole source aquifer. As a result, the environmental document should summarize important opinions from EPA and the state, local, or tribal water quality agencies regarding these impacts and cross-reference the appendix containing the correspondence the agencies or tribe provide. Chap. 20 Page 3 AIRPORTS DESK REFERENCE WATER QUALITY e. Oil response plan. Environmental documents addressing airport actions having above ground facilities to store or handle oil or oil-based products should include information on the status of an oil recovery response plan. See Section 112(a)(2) of the Oil Pollution Act) for more information, if needed. f. Other information. The environmental document should contain information from agencies having expertise on water quality issues. This includes comments on the adequacy of proposed mitigation measures, best available technologies (BATs), and best management practices (BMPs). The environmental document should summarize important information these letters contain and cross-reference the appendix and pages where the letters discussing the particular information may be found. Note: BATs and BMPs typically are parts of the NPDES permit process. BATs refer to the best technology available to minimize water quality impacts resulting from point source discharges. Bacterial decomposition of glycol in stormwater runoff is an example of a BAT. BMPs are schedules of activities, maintenance procedures, and management practices implemented to minimize point source discharge impacts. Examples include using good housekeeping procedures, training personnel in the proper use and handling of chemicals, or using high- pressure water to remove paint from an aircraft instead of solvent-based paint removers. 5. PROCEDURES FOR COMPLIANCE WITH STATUTORY, REGULATORY AND OTHER REQUIREMENTS -ENVIRONMENTAL ANALYSIS. a. Required consultation. Congress has delegated to each state the primary responsibility for protecting and managing water quality within a state’s legal boundaries. Early consultation concerning the topics noted below will improve FAA’s evaluation of an action's water quality impacts and identify any additional information necessary to make judgments about the significance of impacts. It will also ensure the environmental document addresses agency concerns and avoid delays due to the lack of that information. The environmental document’s water quality chapter shall reflect the results of consultation with regulating and permitting agencies and with agencies that must review permit applications, such as the FWS, which may have specific concerns. It should also summarize and appropriately address agency concerns or comments and cross reference pertinent material in the appendix. (1) Water quality standard concerns. Contact the state agency having the authority to enforce water quality standards and/or issue WQCs. (2) NPDES permit concerns. When an airport action would involve a point source discharge, a point source stormwater discharge, or disturb at least 1 acre, contact the state agency or EPA regional office responsible for issuing NPDES permits. (3) Groundwater protection. When an action may affect a sole source aquifer, contact the state, tribal and local government agencies responsible for developing and managing a Comprehensive State Groundwater Protection Program (CSGWPP) and the EPA regional office responsible for reviewing that program. (4) Aquatic populations or communities. When an action would affect fish, shellfish, or wildlife populations, contact the FWS and the respective state fishery or wildlife agency. Chap. 20 Page 4 AIRPORTS DESK REFERENCE WATER QUALITY Note: Consult the National Marine Fisheries Service (NMFS) regional office for actions that may affect anadromous fish or marine mammals. Anadromous fish are fish that live in the ocean but spawn in freshwater (e.g., salmon, shad). 6. DETERMINING IMPACTS. a. General. Determine if building, operating, or maintaining the proposed airport development action would affect project area surface water, groundwater, or drinking water sources. The responsible FAA official should pay particular attention to potential physical (e.g., temperature changes, siltation, and turbidity) and chemical (e.g., changes in oxygen or nitrogen levels, pH, etc.) impacts associated with the proposed action. b. Potential impacts. Actions, such as aircraft and runway deicing/anti-icing, storage tank operation, or firefighting training activities have the potential to chemically affect the project area’s water quality. As needed, describe impacts addressing the following issues: (1) violations of conditions or terms contained in an existing WQC or existing NPDES permit; (2) adverse effects on the water quality of sensitive aquatic habitats, including but not limited to, wetlands or critical habitats for Federally or state-protected species; (3) threats to the integrity of public drinking water supplies; and (4) other areas of concern that water quality agencies identify. 7. DETERMINING IMPACT SIGNIFICANCE. a. General. After completing the analysis discussed in earlier paragraphs, use the findings to determine the proposed action’s degree of impact. For most airport actions, significant impacts can be avoided by design considerations, controls during construction, and other mitigation measures. When the environmental document and appropriate consultation demonstrate that water quality standards can be met, no special water quality problem exists, and no difficulty is anticipated in obtaining permits, it may be assumed that there would be no significant impact on water quality. The responsible FAA official should consider the following factors in consultation with agencies having jurisdiction or special expertise on water quality effects. ORDER 1050.1E THRESHOLD FACTORS TO CONSIDER When an action has the potential to exceed water quality standards, there are water quality problems that cannot be avoided or satisfactorily mitigated, or there would be difficulty in obtaining a permit or authorization, there may be a significant impact. The responsible FAA official should also consider if a proposed action or a reasonable alternative would adversely affect a public drinking water supply, sole source aquifer, or waters of national significance (e.g., wild and scenic rivers, national refuges, etc.). From: Table 7-1, FAA Order 5050.4B. Chap. 20 Page 5 AIRPORTS DESK REFERENCE WATER QUALITY b. Mitigation. During the environmental review process, Federal, state, tribal, or local agencies having permitting or regulatory authority over water quality issues sometimes provide letters addressing those issues. Those letters include measures recommended to mitigate water quality effects for purposes of NEPA that are not required for the certificate or permit. The environmental document should summarize the most important information in those letters and accurately cross-reference the appendix and pages in that appendix for further information. If the FAA of the sponsor does not adopt any recommended mitigation, the environmental document should clearly explain why. In addition, the environmental document should clearly describe the measures the sponsor will carry out to: (1) meet WQC terms or the conditions of any applicable NPDES permits; (2) protect public drinking water supplies or comply with applicable CSGWPPs; (3) develop oil response plans designed to contain any potential spills of oil or oil- based products associated with the proposed action; (4) meet any other substantial water quality concerns that water quality agencies identify; or (5) use BMPs or BATs. Note: 40 CFR Section 112 and 40 CFR Section 112.20(h) present regulations for oil pollution prevention and the contents of a facility response plan, respectively. 8. ENVIRONMENTAL IMPACT STATEMENT CONTENT. a. General. FAA must prepare an EIS if mitigation will not reduce water quality impacts below the significance impact threshold in paragraph 7 above. In addition to the information discussed above, to the extent possible the EIS should contain the following information. (1) The results of added, project-specific, water quality studies FAA and Federal, state, or local water quality agencies agree on during EIS scoping or during the EIS process. (2) A Memorandum of Agreement (MOA) between the Department of Transportation (DOT) and the Department of the Army (Army) contains a provision for elevating disputes concerning dredge and fill permit applications (“Section 404 permit applications”) with the Army. Use of this provision typically occurs when an Army District Engineer is considering denial of a Section 404 permit or requiring conditions that would cause substantial, unacceptable conditions to DOT agencies (e.g., habitat attractive to wildlife hazardous to aviation). Therefore, if an airport action involves a Section 404 permit process that requires the responsible FAA official to elevate permit decisions to Army headquarters, contact the Airport Planning and Environmental Division (APP-400). APP-400 will help the responsible FAA official comply with the provisions of the MOA. APP-400 will also provide the follow-up actions that may be needed at the Washington, D.C., headquarters level to resolve differences. The EIS should contain the results of any dispute resolution process. Chap. 20 Page 6 AIRPORTS DESK REFERENCE WATER QUALITY b. Mitigation. The EIS should identify and describe any mitigation measures that Federal, state, tribal, or local agencies having permitting or regulatory authority over water quality issues recommend for purposes of NEPA in addition to those required as a condition on any water quality permit or license. FAA and the airport sponsor should fully consider the recommended mitigation and balance its benefits against those of the proposed action. The document should explain why the sponsor or FAA has not adopted any mitigation agencies have recommended. If feasible, the EIS should include an estimated schedule for the airport sponsor to undertake accepted mitigation.
