E.1. Good Housekeeping BMP Sweep or vacuum shops floor frequently. Use mopping as an alternative to hosing down work areas. Spot clean any spilled oil or fluids using absorbents or rags. Use dry cleanup methods: Sweep the floor using absorbents. Mop and discharge mop water to the sanitary sewer. Do not pour mop water into the parking lot, street, gutter or storm drains. Remove unnecessary hoses to discourage washing down floors and outside paved areas. Regularly sweep parking lots and areas around facility instead of washing them down with water. Dispose the sweeping in the trash. E-3 For Official Use Only
E.2. Changing Oil and Other Fluids BMP Whenever possible, conduct machinery and equipment fluids indoors. If fluid changes must be conducted outdoors, avoid performing the operations when it is raining or snowing, and perform the work only on concrete or cement covered grounds. Avoid working on asphalt pavements and unpaved grounds. Conduct all liquid cleaning at a centralized station to contain residues in one area. Avoid hosing down work areas; clean up leaks, drips, and other spills using rags or mops for small spills and dry absorbent for larger spills. Keep a drip pan under the vehicle while parts are being removed or serviced. If experience indicate high splash or spill potential during fluid draining, place additional containment measures such as a larger drip plan or absorbent pads on plastic sheeting under the container (drain pan, tub, bucket, etc.) that will receive the fluid. Additional containment measures are required when working outdoors. Designate a special area to drain and replace motor oil, coolant, and other fluids where there are no connections to the storm drain or the sanitary sewer and drips and spills can be easily cleaned up. Transfer drained fluids to a designated waste storage area as soon as possible. Drain pans and other open containers of fluids should not be left unattended unless they are covered and provided with secondary containment (a larger container, bermed area). Store waste fluid containers indoors or under overhead cover to protect from weather with secondary containment or on containment pallets. Antifreeze and waste oil should be stored separately and recycled, or disposed of as hazardous waste. Never pour machinery or equipment fluids or other hazardous wastes into sinks, toilets, floor drains, outside storm drains, or in the garbage. These materials should only be stored in designated storage areas until recycled or disposal as hazardous waste. E-4 For Official Use Only
E.3. Parts Cleaning and Degreasing BMP Conduct parts cleaning and degreasing in dedicated areas indoors. Do not wash, rinse, clean or degrease parts outdoors. Replace organic cleaning and degreasing chemicals with aqueous solution if feasible (same or better performance, cost effective). Collect and reuse the parts cleaning or degreasing solutions to the extent practicable. Use cleaning agents that can be recycled. Dispose spent cleaner or degreaser as hazardous waste unless sampling and analysis is performed, and the waste is determined to be non-hazardous. Never pour spent cleaning or degreasing solutions into sinks, toilets or floor drains. Wastewater generated from steam cleaning need to be collected and managed as oily water and processed through an oil/water separator, or managed as potential hazardous waste. A determination must be made based on potential contaminants or sampling and analysis. Never discharge wastewater from steam cleaning or parts cleaning or degreasing solution on the ground, to a street, gutter or storm drain. E-5 For Official Use Only
E.4. Used Batteries, Break Pads and Other Worn Parts Store used lead-acid batteries in dedicated rooms or cabinets if available until recycling or disposal. Store in secondary containment or on containment pallets. Used dry cell batteries may contain a variety of metals, including cadmium, nickel, lithium, magnesium and zinc. Store used dry batteries in dedicated containers until recycling or disposal. Break pads may contain heavy metals and asbestos. Collect brake pads and all dust from brake pads separately and dispose of the waste properly. Do not dispose as trash. Collect all metal filings, dust, and paint chips from grinding, shaving, and sanding, and dispose by double bagging using heavy-duty trash bags. Large pieces of metals may be recyclable. Paint chips containing lead may require disposal as hazardous waste. Do not dump the material out doors. Never discharge these wastes to the storm drain or sanitary sewer. E-6 For Official Use Only
E.5. Aircraft and Runway Deicing BMPs All of the BMPs are predicated on conformance with applicable Technical Orders and approval by the proper authority (Single Manager). Schedule/prioritize sorties to reduce the number of aircraft exposed to icing conditions. Orient aircraft to take advantage of solar warming and minimize engine icing due to winds. Use mechanical means (plows, blowers) to remove ice and snow from the runway as much as possible. Conduct aircraft deicing in areas where runoff can be captured or retained; avoid areas where runoff enters directly into storm water drains. E-7 For Official Use Only
E.6. Corrosion Control and Outdoor Painting/Paint Removal Operations BMPs Conduct aircraft paint removal indoors if practicable. Avoid physical paint removal operations and spray-painting outdoors during windy conditions. Enclose outdoor painting or paint removal operations with barriers such as tarps or plastic sheeting. Place drop cloth or plastic sheeting on the ground to capture removed paint and during painting. Use vacuums to remove paint chip and dust. Minimize paint and thinner wastes by carefully calculating paint needs. If applicable, collect water used to control over-spray or dust in the paint booth and recycle or dispose properly. Clean high-volume, low-pressure spray guns in a self-contained unit. Recycle or properly dispose the cleaning solution. Wash paint brushes used to apply latex paint with water. Drain wash water to the sanitary sewer. Paint brushes used with oil-based paints and thinners should be contained and placed in a drum for disposal. E-8 For Official Use Only
E.7. Hazardous Material and Waste Storage BMPs Label all hazardous materials and hazardous waste containers. For hazardous waste containers, include storage start date. Centralize storage and distribution of hazardous materials and hazardous waste. Provide roof cover and curbing for centralized storage facilities to prevent storm water run-on and run-off. Store hazardous materials and wastes in areas that can be secured. Store hazardous materials in purpose built lockers that provide secondary containment or on containment pallets. Provide spill kits compatible with the materials stored. E-9 For Official Use Only
