Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	(7) Goodwill The Nitrogen Fertilizer Partnership evaluates the carrying value of goodwill annually as of November 1 and between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. The Nitrogen Fertilizer Partnership's goodwill reporting unit is the Coffeyville Facility. During the second quarter of 2017, there was a sustained decrease in the Nitrogen Fertilizer Partnership’s unit price and continued uncertainty of fertilizer pricing. The Nitrogen Fertilizer Partnership evaluated both positive and negative indicators, including fertilizer pricing market data, to evaluate if a goodwill impairment triggering event occurred during the second quarter of 2017. After assessing the totality of events and circumstances, it was determined a triggering event did not occur and it was not necessary to perform a goodwill impairment analysis as of June 30, 2017. The nitrogen fertilizer business is exposed to seasonal fluctuations in demand, and the second half of each calendar year is typically referred to as the fill season. As of June 30, 2017, the Nitrogen Fertilizer Partnership had not received significant orders for the fill season. If actual pricing is below current market estimates, this could be a trigger for a subsequent goodwill impairment test. If such a triggering event is identified in subsequent quarters, a goodwill impairment may occur.
