PENNVEST Nutrient Credit Trading Program

The Pennsylvania Infrastructure Investment Authority (PENNVEST), working in conjunction with the Department of Environmental Protection (DEP), is hosting auctions for the sale and purchase of nutrient credits in the Susquehanna and Potomac watersheds.

PENNVEST's Nutrient Credit Trading program provides a cost-effective means for regulated public and private waste water treatment plants and other parties to purchase credits to meet their nitrogen and phosphorus discharge limits for the compliance year.

IHS Markit is providing enrollment and eligibility, auctions and registry services to PENNVEST to facilitate these auctions.

PENNVEST will serve as central counterparty and clearinghouse for auction transactions. Credit buyers and sellers will be contracting with PENNVEST thereby reducing risk for buyers and sellers, which in turn should help create a stable nutrient credit trading market in Pennsylvania.
