The temps here at night are getting down into the 30's, so yesterday as I was checking the strength of the antifreeze in the tractors and I started wondering when blended diesel fuel becomes available at the pumps? Anyone know what the trigger is to resume selling winter blend?

In the United States the states do not have legislation on a fixed time frame when winter diesel must meet a specific temperature characteristic. The ASTM D 975 standard does not specify the cold flow requirements of diesel fuel. Instead, it suggests that the cloud point be no more than 6°C higher than the 10th percentile minimum ambient temperature for the month the fuel will be used. The 10th percentile temperature corresponds to the minimum temperature that would be reached no more than 3 days out of 30 for the month (decile). The ASTM D 975 contains overview maps that show the expected tenth percentile temperature for every month for each state.[34]
Using these guidelines gas stations offer "winter ready diesel" for sale to the Motorist - there are two ways to achieve this:
winter blend - the gas station has blended the No.2 diesel with No.1(kerosene) by some percentage.
winterized diesel - the No.2 diesel has been treated with additives by the diesel supplier.
As the treatment with additives (1:40000[35]) is a cheaper way to enhance No.2 fuel in winter, most stations offer winterized diesel in cold weather conditions. In regions with colder weather, most gas stations offer No.1 fuel at the same pump allowing drivers to decide for themselves on a winter blend.
Europe requires winter blend from Dec thru Feb.

There is no government standard but this is what one major retailer of diesel does with their tanks.
They have 2 kinds of store.
If your location is on the Cold weather stores list they start treatment when the temperature falls to +15 and continue no matter what the temperature is till March 1.
If your location is not on the list they only treat if the temperature is expected to be or is +15 or lower.
For +15 to 0 they put one 2.5 gallon jug of additive in tank for every trailer load delivered.
For 0 to -10 they use two jugs additive
Below -10 they use 2 jugs additive in 80% #2 diesel and 20% #1 diesel or kerosene.

Unfortunately I don't think there is one and for those of us that buy more fuel than we burn during seasonal changes it can be an issue. I do what 504 suggested and add a little gas to it. Never had a problem on cold days. Just don't get carried away with it. I stay around 10%.

Here in SE Michigan, our heating oil supplier tells us they switch over to winter grade the first of November. Of course heating oil is typically stored much longer than road fuel, so I wouldn't be surprised if they wait until December before reformulating.

Pretty sure 10% gas to a new style injector isn't a good idea. Pumps around here have a stick on them stating when they switch. Usually some time in Oct. or Nov. You can always be safe and add your own Powerservice or similar additive.
