Hastings NE 2nd Street Subsite OU12 – Excavation, Treatment, and Disposal of MGP Wastes

PRUDENT was selected for the excavation and medium temperature thermal desorption (MTTD) of more than 6,000 tons of former manufactured gas plant wastes and contaminated soils. PRUDENT constructed and operated on-site treatment of over 70,000 gal of contaminated groundwater from excavation operations and storm water management of up to 0.14 mgd. This $3.7M FFP contract included nearly 300 ft of shoring up to 20 ft bgs and stabilization of an electric utility substation as well as a municipal fleet maintenance facility. PRUDENT’s subcontractor mobilized a MTTD unit (up to 500 tons/day) which was sited and permitted under a NDEQ air quality variance in less than two weeks. PRUDENT’s approach saved over $1M as well as reduced truck emissions and transportation of wastes by over 3M ton-miles.
