CLF Sues Barnstable Over Pollution in Lewis Bay HYANNIS — The Conservation Law Foundation (CLF) filed suit recently in federal court in Boston against the town of Barnstable, saying the Barnstable Water Pollution Control Facility is in violation of the federal Clean Water Act and is polluting Lewis Bay.
I
n the suit, CLF contends the levels of nitrogen discharged into groundwater by the plant are too high, and that the nitrogen and other nutrients travel underground to nearby Lewis Bay, where the discharge has elevated nutrient levels that feed large algae blooms. The blooms degrade water quality, lower oxygen levels and harm plant and marine animal life. If the foundation wins the lawsuit, the town's wastewater plant would then be operated under a more rigorous federal permit under the Clean Water Act. Christopher Kilian, director of CLF’s Clean Water and Healthy Forests initiative, said the town’s Comprehensive Wastewater Management Plan proposal to upgrade the plant lacks specificity on two key points. It does not specify how the plant will be modernized and it does not identify where two proposed discharge areas will be located or how much they will add to the volume of wastewater treated at the plant and discharged. The plan should have already identified and permitted the two proposed additional discharge areas, he said, adding that the 30-year rollout of the wastewater plan is too slow. “You can’t have a plan dragged out for 30 years with no specificity or commitment to real action,” he said. “That’s what we’re looking for, getting past empty promises and loopholes.” One alleged loophole is the reliance on a state discharge permit that allows higher levels of nu-

trients on the assumption that nitrogen and other contaminants will be filtered out of the treated water on its trip to coastal water bodies. But Kilian said that is not happening and that groundwater is actually acting more like a pipe than a filter. That direct connection from wastewater discharge to the ocean via groundwater was recently affirmed in a Supreme Court decision concerning discharge in Maui. It was the basis for two other successful CLF lawsuits in recent years at two resorts in Harwich. The Wychmere Beach Club and the Wequassett Inn reached settlement agreements with CLF to reduce nitrogen levels flowing into marine water from their treatment plants as a result of the lawsuits. continued on page 61
