Best Management Practices Analysis of Best Management Practices (BMPs) for Piedmont Triad Airport Authority (PTAA) and NPDES Co-Permittee operations is conducted annually in order to minimize the risk of stormwater pollution at the Airport. The structural BMPs listed in the North Carolina Department of Environment and Natural Resources (NCDENR) BMP Toolbox for Public Airports and the procedural BMPs listed in the United States Environmental Protection Agency (EPA) Industrial Stormwater Fact Sheet Series "Sector S: Vehicle Maintenance Areas, Equipment Cleanine Areas, or Deicine Areas Located at Air Transportation Facilities" are being considered in whole or in part for current operations and future development. Pertinent aspects of applicable regulations including Jordan Water Supply Nutrient Strategy rules, Randleman Lake Water Supply Watershed rules, and the PTAA Water Supply Watershed Management and Protection Rules require application of appropriate stormwater BMPs. In addition, major aspects of PTAA's current development program are subject to the conditions of issued Section 401 (of the Federal Clean Water Act) Water Quality Certifications from the NCDENR Division of Water Resources (DWR), which specify BMPs for stormwater discharge. The need for additional BMPs will be based on the assessment of potential sources to contribute significant quantities of pollutants to stormwater discharges and the data collected through the stormwater monitoring programs. The status of structural BMPs potentially applicable to existing and future development at PTIA are summarized in Table 4.1. Each PTIA co-permittee is requested to complete the SPPP Annual Compliance and Exposure Reduction Feasibility Survey by January 31st every year. This survey requires review of the technical and economic feasibility of changing method(s) of operation(s) and/or storage practices to eliminate or reduce exposure of materials and processes to stormwater. Procedural BMPs in place and/or for potential consideration at PTIA are listed by pollutant source in Table 4.2 Table 4.1 Airport Structural BMPs Airport BMP PTIA Status Sheet flow, Level Spreaders, and Vegetative Filter Strip Constructed and in use at PTIA Grassed Swale Constructed and in use at PTIA Bioretention Not currently in use at PTIA Infiltration Devices (Infiltration Basin and/or Trench) Soil types and earthwork compaction requirements have precluded this practice at PTIA to -date.

Significant Changes Changes in design, construction, operation, or maintenance at the Piedmont Triad International Airport (PTIA) that have a significant effect on the potential for the discharge of pollutants to surface waters require amendment of the Stormwater Pollution Prevention Plan (SPPP) during annual review. Annual SPPP revisions have included: • Lists of significant spills or leaks of pollutants for the previous three years, or the notation that no spills have occurred. • Re -certification that active Stormwater Discharge Outfalls (SDOs) have been evaluated for the presence of non-Stormwater discharges. • Re-evaluation of the effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management Plan - completed Annual Compliance Surveys and Semi -Annual Facility Inspection Surveys document preventative maintenance and good housekeeping and the facility inspections. • Tiered Monitoring Responses include documentation of atypical conditions noted during qualitative monitoring and tiered responses to benchmark exceedances recorded during routine and deicing event analytical monitoring. • Employee SPPP Training. • Annual certification that PTIA is in compliance with 40 CFR Part 449.10(a) by not using airfield deicing products that contain Urea. The following changes in industrial activities at PTIA with potential to affect stormwater runoff have occurred since July 1, 2010: • Construction projects (no change in NPDES criteria) - o New Runway 5L/23R o Taxiway E o Honda Production Facility o Taxiway K Extension o Taxiway E Extension o Taxiway D Extension o Aircraft Rescue and Fire Fighting (ARFF) Station o Timco Apron Widening o Honda Maintenance Repair and Overhaul (MRO) Facility o Honda Connector Road o Taxiway M Extension • Completion of the New Runway 5L/23R and the Fed Ex and Honda facilities resulted in compliance monitoring adjustments (NCDENR concurred 06/25/2012) - o SDO 021 outfall (and monitoring) eliminated, stormwater rerouted to SDO 020 o SDO 022 outfall (and monitoring) eliminated, stormwater rerouted to SOO 023 o Fed Ex Pond 2 Inlet 34 monitoring discontinued due to non-SDO status o Fed Ex Pond 3 Inlets 35 and 37 monitoring discontinued due to non-SDO status o Honda Pond 1 Inlet 39 monitoring discontinued due to non-SDO status o SDO 040 monitoring added at completion of Honda Production facility o SDO 062 monitoring added at completion of New Runway 5L/23R o SDO 003 moved approximately 200 feet downslope at completion of Honda MRO facility • Repair and downstream stabilization of SDO's 023, 030, and 033 recommended by NCDENR based on monitored turbidity benchmark exceedances (NCDENR concurred 09/08/2014) Piedmont Triad International Airport NCS000508 NPDES Permit Renewal Application Page 1 of 2 1112612014 Supplemental Information Required for Renewal of Individual NPDES Stormwater Permit Significant Changes (continued) Updates to the 2010 Tenants (NCDENR notified 12/05/2011) result in potential Co-Permittee changes (see Table 5.1 for list of suggested 2015 Co-Permittees) - o DynamicAirways and JBTAeroTech are new (since 2010) PTIA tenants o Alamo/National Car Rental and Enterprise Rental Car share facilities; Carolina Aircraft and Koury Aviation share facilities; Delta Airlines, Frontier Airlines, and Delta Global Services share facilities; Allegiant Air industrial activity is the responsibility of Quontem Aviation Services; Jetstream Ground Services is responsibility of Envoy, Piedmont Triad ARFF Station/Command Ctr. is the responsibility of Piedmont Triad Airport Authority (PTAA); Avis Rent A Car merged with Budget Rent a Car, Continental Airlines merged with United Airlines; US Airways merged with American Eagle and are now Envoy; Cessna is now Textron Atlantic Aero has been acquired by Landmark; and Timco is now Haeco Airframe Services. o Chotouqua Airlines (now Republic Airlines), Sondhill Delivery Service, TAA Flight Training, Triad Transportation, and Worldwide Flight Services present no exposure potential.

Impractical due to space constraints and cost to construct. PTIA is considering designating dedicated locations to deice aircraft on the existing aprons to minimize exposure Apply anti-icer to aircraft that will be parked overnight to make it easier to remove accumulated snow and ice in the morning. Apply anti-icer to aircraft immediately after deicing to provide extended hold -over time prior to take -off. Ensure that stormwater inlets are blocked when deicing/anti-icingcleicing/anti-icing during dry weather. Use mechanical vacuum systems or other devices to collect aircraft deicing runoff from the apron surface for proper disposal. Dispose collected aircraft deicing runoff to sanitary sewage facility (if allowed by sewer authority), on -site treatment or recycle resell or reuse). Use portable tanks, retention and detention ponds for temporary storage of collected deicing runoff. Currently in place at FedEx facility. Commercial and GA aprons would require significant upfit to facilitate this operation Collect contaminated runoff in a wet pond for biochemical decomposition (be aware of attracting wildlife that may rove hazardous to flight operations). Inconsistent with FAA AC 150/5200-33B due to potential for wet pond to attract wildlife Recover and recycle/dispose of unused deicing fluids in deicing trucks. Recover deicing materials when applied during non -precipitation events (e.g., covering storm sewer inlets, using booms, installing absorptive interceptors in the drains, etc.) to prevent materials from later contaminating stormwater. Deicing/anti-icing Evaluate and optimize present chemical application rates runways and Use sand where possible to enhance friction. Using sand or salt as deicers and anti-icers in airports can cause damage to aircraft surfaces and mechanical parts Plow and broom runways prior to application of deicing chemicals.
