In July 2014 the EPA issued a ruling that RNG produced from landfills would qualify as D3 RIN qualifying fuel under RFS2. In one month’s time, D3 RIN generation soared from the 4,000 recorded for July to 3.49 million for August 2014. As can be seen by the 4,000 D3 RIN credits issued in July 2014, industry had made little progress at developing an economically viable D3 fuel prior to the EPAs ruling that RNG from landfills would qualify as a D3 fuel.
