5 To clarify the Aircraft Operations process, several subprocesses are listed: Fluids replacement/purging Buildup/parts replacement Parts repair Weapons system cleaning Check your manual for greater detail on how to apply pollution prevention OKR_ Unit 2 - Section 3 - Slide No. 5

6 Pollution Prevention Solutions Let s look at how to examine your activities to: identify pollution prevention solutions achieve the Air Force goals promote a healthy work environment OKR_ Unit 2 - Section 3 - Slide No. 6

7 INPUTS: Applying the Source Reduction Principle What input materials do you use to do your job? Which of those input materials are: hazardous to your health? hazardous to the environment? result in a waste? OKR_ Unit 2 - Section 3 - Slide No. 7

8 INPUTS: Applying the Source Reduction Principle Are some of your input materials more hazardous than others? Which hazardous input material do you use most? Which hazardous input material generates the most hazardous waste? OKR_ Unit 2 - Section 3 - Slide No. 8

9 CAUTION HAZARDOUS MATERIAL Who can help you determine whether the products you use are hazardous? HMP is responsible for purchasing all hazardous input materials If you use hazardous input materials in your shop, they must be supplied through HMP BE is responsible for approving the use of all hazardous input materials BE looks at the health effects Environmental Flight is responsible for managing environmental compliance They can help you identify suitable substitute input materials for your shop that are non-hazardous OKR_ Unit 2 - Section 3 - Slide No. 9

10 To protect your health and our environment, you want to eliminate or substitute input materials that contain EPA 17, EPCRA, and ODS goal area chemicals OKR_ Unit 2 - Section 3 - Slide No. 10

11 EPA 17 and EPCRA chemicals are health hazards, and they tend to result in hazardous waste or air pollution These chemicals are in widespread use ODSs also are strictly regulated and controlled because they are believed to harm the environment OKR_ Unit 2 - Section 3 - Slide No. 11

12 EPA 17s The EPA 17 chemicals make up a large part of the EPCRA chemicals and air emissions normally found on Base Targeting these chemicals for your reduction efforts is the key to meeting the Air Force pollution prevention goal OKR_ Unit 2 - Section 3 - Slide No. 12

13 Source Reduction Options for Your Process Group Using bulk oil dispensing systems to reduce MSW and raw input material costs Using longer-lived synthetic oils instead of petroleumbased oils Using a rag to wipe up small oil/fuel drips or spills instead of absorbent; this eliminates the waste absorbent and the unsaturated rag can be washed Directing all painting to Corrosion Control and eliminating the purchase of spray paint OKR_ Unit 2 - Section 3 - Slide No. 13

14 Summary of Categories, Products, and Affected Goal Areas for AETC Aircraft Operations Category Product Goal Area Constituent Solvents/Cleaners Sealing Compound CS 3300 Lead Cleaner 1,1,1-Trichloroethane Solvent, Stripper Freedom 11 Methylene Chloride Formic Acid Toluene Lubricants Lubricant, AD Per Mil-L23389 Methyl Ethyl Ketone (Assem Lube) Toluene Freon 113 Break-Free CLP, Liquid 1,1,1-Trichloroethane Phenol Penetrating Oil 597D Lead Lubricant, Perma-Slick Xylene Sealants Sealant, Locking Compound 1,1,1-Trichloroethane 40 Chromium Compounds Sealant, Corrosion Resistant Ethylbenzene 4150 Sealer Xylene Adhesives Adhesive, Acrylic Carbon Tetrachloride Superbonder 499 Thermal Hydroquinone Cycling Resin Contact Cement, MA-162 Scotch-grip 847-L Rubber & Gasket Adhesive Toluene Toluerne Goal Area Affected EPA 17, EPCRA ODS, EPA 17, EPCRA EPA 17, EPCRA EPCRA EPA 17, EPCRA EPA 17, EPCRA EPA 17, EPCRA ODS, EPCRA ODS, EPA 17, EPCRA EPCRA EPA 17, EPCRA EPA 17, EPCRA ODS, EPA 17, EPCRA EPA 17, EPCRA EPCRA EPA 17, EPCRA EPA 17., EPCRA EPCRA EPA 17, EPCRA EPA 17, EPCRA OKR_ Unit 2 - Section 3 - Slide No. 14

15 Things to Remember You can substitute or eliminate input materials within the boundaries set by your TOs You can initiate the TO change process and have your idea reviewed by the appropriate people (see Unit 4, Generating New Options) OKR_ Unit 2 - Section 3 - Slide No. 15

16 Let s look at the pie charts in Section 10 Aircraft Operations contributes: 2% to EPA 17 chemical usage 2% to ODSs chemical usage 8% to EPCRA chemical usage Even though your process group is not a major contributor: You still need to make every effort to reduce the use of hazardous chemicals Your activities will have a major impact on whether your Base meets, or even exceeds, the Air Force pollution prevention goals OKR_ Unit 2 - Section 3 - Slide No. 16

17 Some Final Areas to Consider under Inputs Store your input materials correctly Improper storage or failure to use products before their expiration dates can produce health hazards, fire hazards, or unnecessary hazardous waste Input materials kept on hand past their expiration dates can account for as much as 15% of a Base s hazardous waste stream Exp. 8/94 Exp. 6/92 This end up Exp. 2/96 An operational HMP can reduce or eliminate problems with material expiration It s your responsibility to avoid storing excess or expired products OKR_ Unit 2 - Section 3 - Slide No. 17

18 PROCESS: Applying the Process Modification Principle Shop Flightline Maintenance Phase Docks Life Support Process Prepares the aircraft for flight, performs minor maintenance, and conducts post-flight inspections Assembles, disassembles and performs minor maintenance associated with scheduled and unscheduled maintenance Maintains the helmets and oxygen units issued OKR_ Unit 2 - Section 3 - Slide No. 18

19 Remember: Aircraft Operations (continued) Tasks are the most basic unit of activity that can be used to identify and communicate potential hazards or impacts on the environment Tasks are the building blocks for describing processes Examples include: lubricating a part binding a part with adhesive soldering cleaning a specific part purging a fluid OKR_ Unit 2 - Section 3 - Slide No. 19

20 PROCESS: Applying the Process Modification Principle (continued) To evaluate your processes, start by evaluating basic tasks. Ask yourself: Do I need to do this task? Is there a better way to do this? Can this task be changed to save time, prevent pollution, reduce health risks? Can I modify this process to eliminate or reduce the waste generated? Think about what you do, why you do it, and how you do it OKR_ Unit 2 - Section 3 - Slide No. 20

21 PROCESS: Applying the Process Modification Principle (continued) Some of the solutions used or considered by your process group include: Wiping on a chemical instead of spraying it Using a rag more than once before throwing it away Testing fluids and basing changeout on need rather than schedule Using reusable sorbent pads and wringers to reduce sorbent waste Using a jet washer instead of a solvent dip tank system Schedule Coordinating with a shop that has a jet washer and arranging to use its equipment for cleaning OKR_ Unit 2 - Section 3 - Slide No. 21

22 As you consider your proposed modification, be sure you are truly eliminating pollution and not just transferring the pollution to a different medium Burning your trash would reduce the volume of waste going to the landfill, but open burning also can create an air pollution problem Consider all the effects your change could have Everything you do affects the process, your health, and your environment OKR_ Unit 2 - Section 3 - Slide No. 22

23 OUTPUTS: Applying the Recycling, Treatment, and Disposal Principles At this point, you have: considered all the source reduction possibilities already substituted non-hazardous materials to replace hazardous ones investigated process modification to reduce or eliminate your waste If you still have waste: consider the pollution prevention principle of recycling OKR_ Unit 2 - Section 3 - Slide No. 23

24 OUTPUTS: Applying the Recycling, Treatment, and Disposal Principles (continued) Recycling and recovery extend the life of your materials Recycling is the process by which materials are transformed into new products Examples of materials that can be recycled include: Cardboard boxes Spent batteries Plastics Wooden crates Precious metals Glass Scrap metal Oil filters Paper OKR_ Unit 2 - Section 3 - Slide No. 24

25 OUTPUTS: Applying the Recycling, Treatment, and Disposal Principles (continued) Empty containers such as 30- and 55-gal drums also can be reused numerous times before disposal as scrap metal Reusing empty containers depends on what chemical was stored in the container; check with HMP or Environmental Flight to ensure safe reuse Remember: Recycling markets change all the time; what is not recyclable today, may be recyclable tomorrow OKR_ Unit 2 - Section 3 - Slide No. 25

26 OUTPUTS: Applying the Recycling, Treatment, and Disposal Principles (continued) Recycling and recovery (continued) Recovery is the process of obtaining materials or energy resources from solid waste Examples of materials that can be recovered include: Used, unsaturated rags Purged oil Purged hydraulic fluid Purged fuels Parts washer solvents OKR_ Unit 2 - Section 3 - Slide No. 26

27 OUTPUTS: Applying the Recycling, Treatment, and Disposal Principles (continued) If the waste cannot be recycled or recovered: pollution prevention has not been achieved the waste you have created must be disposed of in an environmentally safe manner However, there are ways to treat your wastes to make them less hazardous and/or reduce their volume Treatment is not pollution prevention, but it can reduce the cost of waste disposal Your process group is successfully using volume reduction techniques with Basic Post Flight (BPO) wastewater generated from armament cleaning OKR_ Unit 2 - Section 3 - Slide No. 27

28 OUTPUTS: Applying the Recycling, Treatment, and Disposal Principles (continued) Aircraft Operations Top 5 Waste Streams The process flow diagram provides a list of the hazardous and non-hazardous wastes produced by your process group. It also identifies the inputs responsible for generating air emissions. The top five waste streams for your process group are: Purged JP-8 Purged Oil Purged Hydraulic Fluid Spent Batteries Rags and Absorbents Your goal should be to find ways to eliminate or reduce these waste streams. OKR_ Unit 2 - Section 3 - Slide No. 28

29 OUTPUTS: Applying the Recycling, Treatment, and Disposal Principles (continued) Check the pie charts in Section 10 and see how much hazardous waste this process group is responsible for generating within the Command OKR_ Unit 2 - Section 3 - Slide No. 29

30 Some Final Areas to Consider under Outputs Keep hazardous waste away from non-hazardous waste Remember the mixture rule: Anything that comes in contact with a hazardous waste becomes a hazardous waste itself Waste containers that are kept outside must be water-tight If rain gets in your waste container, it becomes hazardous waste and increases the volume you have to dispose of, increasing costs Mismanagement of waste can create health risks, increase pollution, and significantly raise waste disposal cost OKR_ Unit 2 - Section 3 - Slide No. 30

31 Most Applicable Regulations Requirements of RCRA, EPCRA, PPA, and CAA all will significantly affect the activities of your process group Your process group accounts for only about 1% of the hazardous waste generated by AETC But RCRA s requirements for handling and storage are cumbersome, so it is to your advantage to eliminate as much waste as possible PPA applies to all users of hazardous input materials and generators of pollution You need to apply pollution prevention principles to reduce hazardous input material usage and pollution generation OKR_ Unit 2 - Section 3 - Slide No. 31

32 Most Applicable Regulations Requirements of RCRA, EPCRA, PPA, and CAA (continued) Approximately 8% of the EPCRA chemicals purchased by the Command are for your process group EPCRA chemicals are predominantly contained in solvents, cleaners, lubricants, and sealants; these products should be a main targets for your source reduction efforts CAA is not a major concern since your process group is responsible for only about 1% of the VOCs in the Command You may be required to modify some of your processes or maintain certain records OKR_ Unit 2 - Section 3 - Slide No. 32
