"The Environmental Protection Agency is expected to make a final decision next month on whether cities should be allowed to release partially treated sewage during heavy rainfalls despite concerns the policy would increase the incidence of waterborne disease. The policy change, called "sewage blending," was proposed by EPA more than a year ago and has attracted nearly 100,000 written comments from industry, state and local officials, interest groups and the public.
Local sewerage agencies have lobbied heavily for the change, saying they need an affordable solution to the problem of treatment plants that become overwhelmed by heavy flows during rainstorms and snowmelts. The alternatives, sewage treatment operators say, is to either release the excess sewage entirely untreated or spend billions of dollars upgrading treatment plants and sewerage systems across the country.
"What we are fighting for is to preserve what we view as a management practice to (achieve) as much treatment as possible in an extreme wet weather event," said Alexandra Dunn, general counsel for the Association of Metropolitan Sewerage Agencies. The policy change is also expected to benefit builders and developers, allowing local governments in fast growing areas to lower impact fees or to lift moratoriums on new sewer hookups.
However, environmentalists, scientists and some states have criticized the proposal as a rollback of environmental and public health protections. "We think EPA should enforce the law to protect public health, not change the law to protect the poor practices that are threatening public health," said Nancy Stoner, an expert on water policy with the Natural Resources Defense Council. "If this policy is finalized, more Americans will get sick from waterborne diseases, which are life threatening for small children, the elderly, cancer patients, and others who are already weakened by illness," Stoner said. The Washington State Department of Ecology called the proposed policy change "environmental backsliding" in comments filed with EPA. The Florida Department of Environmental Protection said the policy will undermine the state's efforts to get waste treatment operators to upgrade their facilities and may not provide "sufficient protection against discharges of pathogenic organisms."
