Seattle will be the first city to test the new integrated framework.

At a U.S. House of Representatives subcommittee hearing on July 25, a panel of water managers and local government officials said that the U.S. Environmental Protection Agency’s new framework for stormwater and sewage projects is a necessary reform, but it does not go far enough in limiting costs for communities that are struggling financially.
“The only substantive relief provided by the framework is scheduling,” said David Berger, mayor of Lima, Ohio. “It allows cities to prioritize cost-effective actions, but low-priority, low-benefit actions appear still to be mandated at a later date.”
Nearly two decades ago, the EPA introduced a policy for controlling municipal sewer overflows from pipes that carry both stormwater and sewage. The policy has proven to be chokingly expensive for cities, utilities, and their ratepayers. Many utilities have spent billions of dollars to build pipelines and subterranean holding tanks, as well as to expand treatment capacity.
Last summer, for instance, the Metropolitan St. Louis Sewer District signed a record $US 4.7 billion Clean Water Act settlement to reduce the amount of raw sewage and polluted surface runoff entering local waterways. Since 1998, more than 40 communities have signed similar agreements with the EPA.
But because of the cost of these agreements — and the realization that other pollution-control projects might result in greater benefits — last fall, the EPA began taking public comments on a new strategy, called an integrated planning framework.
In June, the agency released the final version of the strategy, which seeks to give communities more flexibility in meeting water-quality goals. The voluntary process also encourages use of green infrastructure, or natural water-absorbing systems such as wetlands and grass roofs that could cut compliance costs in the long run.
The water-quality requirements of the Clean Water Act are still paramount, but the integrated framework allows a city choose the sequence in which it will take on projects.
“This is the administration’s way for communities to take a broader look at clean water, said Katherine Baer, director of the Clean Water Program for American Rivers, a conservation group, in a phone interview with Circle of Blue. “This is about finding smarter, more cost-effective ways to meet existing standards.”
This Or That? Or Both?
The cause of all this fuss is the “combined” sewer. Roughly 772 communities are served by these combined systems, in which stormwater and sewage flow into the same pipes. Heavy rains will periodically overwhelm a combined system’s flow capacity and force a utility to dump raw sewage along with surface runoff that can be laced with oils, grime, and chemicals into water bodies.
The EPA press office did not respond to Circle of Blue’s request for an interview on how the integrated planning framework was developed and how it would be implemented; rather, the press office provided a statement that basically re-stated the framework’s main points. People working for local water agencies, however, were willing to discuss the framework’s strengths and weaknesses.
Mark Pestrella, the assistant director of the Los Angeles County Department of Public Works, told Circle of Blue that the EPA is making a good attempt at recognizing that water is managed by many agencies, but the framework falls short of truly integrated water resources management.
“The EPA is saying, ‘You can take an integrated approach, but only to look at the two regulatory areas that we deal with,’” said Pestrella, who is also the stormwater committee co-chair for the National Association of Flood and Stormwater Management Agencies. Pestrella explained that a good case in point is water supply, which is a bigger problem for cities in Southern California and the Southwest, and which is not included in the new guidance.
Because the framework is written with such general language, Pestrella said that taking on the challenge of developing an integrated plan might prove too daunting for small communities which do not have the money, the technical expertise, or the political will that big cities do.
Baer, of American Rivers, echoed this latter point, as did George Hawkins, the general manager of the District of Columbia Water and Sewer Authority, who was a witness at the House hearing last week.
“There are many jurisdictions that do not have the capability even to get to the negotiating table,” Hawkins said, because of the level of research and analysis that is necessary to evaluate an integrated plan. His agency spent $US 2 million on preparatory work before even sitting down with the EPA.

Many water managers, both at the hearing and in conversations with Circle of Blue, said that the framework does little to control costs, especially if all the framework does is shuffle the construction line-up.
Nancy Stoner, the EPA’s top water official, told the House subcommittee that the new guidance is not as rigid as is commonly assumed.
“Certainly needs are great,” she said. “But we think we have the flexibility now, under the framework, to address [cost concerns] as best as we can, in partnership with state and local communities using the resources available.”
Seattle, however, does have those resources. The largest U.S. city in the Pacific Northwest is one of the few large American cities without a consent agreement with the EPA for combined sewer overflows. Because those negotiations are now underway, Seattle will be the first U.S. city to find out how the new policy works in practice.
In May, Seattle officials announced a proposed agreement with federal and state regulators that will allow sewage and stormwater projects to be managed in tandem. The city, which expects to spend $US 500 million on capital infrastructure to implement the agreement, will submit a draft integrated plan by the end of 2014.
Since 1968, Seattle has spent $US 524 million (measured in 2009 dollars) to control overflows from combined sewers. This has reduced the annual polluted discharge by 75 billion liters (20 billion gallons), yet the city is still not in compliance. Nancy Ahern, a deputy director at Seattle Public Utilities, told Circle of Blue that the utility is trying to find the highest-priority stormwater projects to swap places in the timetable with combined sewer projects.

“We’re not talking marginally better projects,” Ahern said. “We’re talking 20, 30, or 40 times the pollutant removal, compared to the combined sewers.”
Even though the city will still have to meet the state standard of one sewer overflow per outfall per year by 2025, delaying the less beneficial projects is a smart move, says Ben Grumbles, who was an EPA assistant administrator for water from 2003 to 2008. He is now the president of the non-profit Clean Water America Alliance.
“It may turn out,” Grumbles told Circle of Blue, “that more cost-effective solutions are developed over time. Those less important requirements may be easier to meet down the road.”
Meanwhile, many eyes will turn to the Pacific Northwest, to see what an integrated plan looks like, how it is implemented, and whether it can deliver the benefits promised.
