Only contractors who are NMACC III Pool 1 awardees are eligible to participate in this restricted competition. Evaluation will focus on environmental compliance factors including CERCLA requirements and construction permits, schedule and phasing capabilities, and price, with price being weighted more heavily than non-price factors.
