If you exam the certifications on the EPA website (open to public), you'd see that the EPA did retest a significant number of results from manufactures (Lucid included).
Notice that manufacturers have option of keeping their number, or the EPA number, whichever LOWER.
Moreover, I believe most manufacturer do not conduct the EPA test themselves, majority of them sent out the work to an independent contractor/facility in Arizona.
Simply entering the manufacture info (and model) into this link. The results are quite comprehensive.
