Premise: The benefits to be gained in air quality were calculated by EPA for the first six years (including the interim program) to be reductions of 125,000 tons of hydrocarbons, 2,388,000 tons of carbon monoxide and 450,000 tons of nitrogen oxide.

Hypothesis: The EPA have calculated that there will be no benefits for air quality because the number of hydrocarbons will increase.
Relation: contradiction
