The private club on State Road has staged shoots since the late 1800s. Animal-rights activists have opposed the activity for decades but have failed to persuade state legislators to ban it.
In the last few years, the Riverkeeper environmental group has taken aim at the shoots from a new angle - water pollution and river safety.
The group and the club have been at odds over the need for a permit from the state Department of Environmental Protection, network lawyer Nicholas Patton said.
"This is a big change in their position," he said.
But the settlement does not require the club to obtain the National Pollutant Discharge Elimination System permit, the club's lawyer said - only to apply for it by Dec. 31.
Patton replied, "It will be up to the Department of Environmental Protection to evaluate the permit and apply Clean Water Act standards."
The network, based in neighboring Bristol Borough, will monitor the club's permit and "undertake efforts to ensure that those who recreate on the river during the club's shooting activities are not injured by the spray of shotgun pellets," Delaware Riverkeeper Maya van Rossum said in a statement.
The club has a three-story cloth screen to keep gunshot out of the river, and posts employees in boats to retrieve dead and injured pigeons, Corr said.
Members use nontoxic shot, which is legal for hunting migratory waterfowl, he said.
