Club Forum: Fish Impacts by the Delaware City Refinery, July 9, 2012
Join us for a discussion of the topic of fish impingement at the Delaware City Refinery. The once-through cooling system infrastructure has significant impacts on the Delaware River and Bay's fish populations.

The Delaware City Refinery utilizes water withdrawn from the Delaware River as part of its once-through cooling system. As part of this process, enormous quantities of fish are killed as they are impinged and entrained against the intake screens which are more than fifty years old and have not been updated with advanced technology that represents the industry standard of best practice. The refinery also releases heated water back into the river, which changes the thermal characteristics of the river ecosystem, impacting the health and vitality of the Delaware River’s aquatic environment. Complicating the environmental and economic impacts of fish impingement, entrainment and thermal pollution, the Delaware City Refinery is operating under a permit that expired in 2002.
The commercial and recreational fisheries of the Delaware River and Bay are managed by state agencies that have placed harvest limits and moratoriums on numerous river species for commercial and recreational fishing. Recreational fishing limits include the following:
American shad, limit 10
Atlantic sturgeon, moratorium
Black drum, limit 3
Black sea bass, limits 15-25 depending upon season
Blue crabs, limit 1 bushel
Bluefish, limit 10
Clams, 50 for residents, 100 for non-residents
Red drum, limit 5
River Herring (alewife and blueback herring), moratorium
Spanish mackerel, limit 10
Striped bass. limit 2, except for catch and release only on spawning grounds in spawning season
Summer flounder, limit 4
Tautog, limit 3-5, depending upon season
Winter flounder, limit 2
The Delaware City Refinery’s fish impacts therefore not only impact the river and its ecosystem, but also recreational value of the Delaware River and Bay and the livelihoods of commercial fishermen.
The Delaware Chapter of the Sierra Club invites you to participate in this Club Forum, which will help us to better understand the impacts of the Delaware City Refinery on the Delaware River, Delaware Bay, and surrounding communities, as well as opportunities for improvements to the refinery to mitigate these impacts on our fisheries.
