1*You can never have enough 5 gallon buckets stashed around.
It's surprising what all they can be used for.
2*Looks like the EPA would be after them for that if they knew about it.
Sadly yes, but its one of those things, cost of doing business and the nature of the beast.
Think about the next time your swimming in your favorite lake. Think of how many 2 stroke outboards are run in it. NOw assume everyone mixed at 50:1 and never richer, that one gallon of oil for every 50 gallons of gas. At my lake you could easilly say 10,000 gallons of fuel are burned a year on it, no idea how to guess this and this is totally a guess. That is 200 gallons of oil that comes out as carbon and the unburned parts that are not burnt in combustion. Or lets take oil based paints used for timber marking. EPA will not let you pour out gallons of it a day, but in a 6 hour day i could squirt out 1-2 gallons of the stuff, most of which is rubbed off on the way to the loading area or oversprayed on the bushes and ground to begin with, as well as knocked off by the loader while being merchandised and loaded, end result lets say 75 % gets knocked off in the woods the other 25% makes it to the mill. That is lets say a 100 acre marked timber sale that used lets say i can mark 7 acres a day (not to heavy of a stand) if i use 1.5 gallons of paint a day thats 22 gallons rounded up to account for boundry line marking as well. so 75% of that is 16.5 gallons of paint that end up on the ground in the woods anyway. The other 5.5 gallons either fall off on the road, are sold to mulch places to go in consumers flowerbeds or are burned as boiler fuel at the mill (where the bark goes after it is debarked from a tree). All this being said i think the EPA would frown upon me taking 16.5 gallons of paint and walking through the woods pouring it out, but done the corect way its acceptable as a use for the product. This is just the way it is till things formulations change and we have to deal with it and accept it. I recycle my oil, bottles and cardboard, i dont try to pollute in anything i do, but this is just the way it is. A hose that leaks sprays preasureized fluid out over say a quarter mile while driving back to the dock you cant get that up. No logers use the veggie based things as its to expensive.
Another example is prescribed fire, where i use to work on a good day we could use 150 gallons of tourch fuel. Torch fuel is either 50/50 deisel gas or 60/40 deisel gas, depending on conditions and who mixes it. Is is ok to just tourch off 100 gallons of this stuff to watch it burn, no. Use it in an approved forestry manner , yes. Also there is a percentage of the stuff that does not burn, i would put it into the 1% area unless your in a lot of hardwoods where the fire just creeps and does not total burn, so you have several gallons that go unburned and just spilled on the ground.
