Yesterday, New York City Mayor Michael Bloomberg announced the city’s 10-year Waterfront Vision and Action Agenda.  New England cities should take note of this forward-thinking plan, which knits together a dizzying array of restoration activities to ensure that NYC’s rivers, harbors and 500-mile waterfront remain world class amenities for its residents and visitors.

The waterfront plan incorporates key elements of NYC’s Green Infrastructure Plan, released last September.

Among other things, NYC plans to invest over $4 billion over the next 20 years in modernizing infrastructure to control pollution to the city’s waterways.  Recognizing it would need to invest huge sums to protect and enhance its critically valuable waterfront, the city did its homework.  Experts found that using green infrastructure approaches to reduce sewer overflows over the 20 years would result in cost savings of $1.5 billion.  NYC’s vision for restoring water quality now includes a mix of strategic investments in some “grey” or hard piped infrastructure – the sort cities have employed for the past century – along with a hefty proportion of green technologies.  In addition, the plan includes $900 million in private investment.

One inch at a time

Green stormwater management techniques, often referred to as “Low Impact Development,” model nature’s way of handling runoff from paved areas during storms – the runoff is cleansed by soil and plants in vegetated areas, then evaporates or is filtered back into the ground.  Wetlands, green roofs and even specially designed rain gardens and street trees can serve this function.  Dumping polluted stormwater runoff into natural wetlands isn’t on its own an acceptable solution, so green infrastructure approaches add new vegetated areas where the treatment occurs.

The status quo is that street runoff co-mingles with human wastewater in the sanitary sewer system, overwhelming the pipes and treatment plants.  Instead, the city plans to send street runoff into new green treatment areas designed to manage stormwater.  NYC has set its sights on diverting runoff from the first inch of rainfall from 10% of paved area. Keeping this quantity of runoff out of the combined sewer system, experts predict, will have dramatic water quality benefits.

Everybody pays, everybody wins

NYC’s waterfront vision is an impressive example of coordination across a tangle of city and state agencies, public and private entities.  The city’s action plan to cut back sewer overflows relies on public and private entities to restore water quality over the next 20 years.  The city will soon require new development to include state-of-the-art stormwater management, recognizing that private property owners will benefit from the improved waterfront and the public goals cannot be accomplished without their contributions.  If all goes as planned, many more New Yorkers will enjoy views of blue harbors from atop green roofs…

It’s difficult to imagine a day like today in Boston without the aid of salt to make our roads safe to use. For those of us in the snowier parts of the country, road salt is a necessary and accepted part of our winter. It’s cheap, effective and it allows commuters, motorists and emergency vehicles to safely reach their destinations in harsh conditions. According to the Salt Institute, Americans used 22 million tons of road salt in 2008. In a different study by the National Research Council, Massachusetts tops the list of of states with the highest road salt-use at, 19.94 tons per lane-mile each year, surpassing even New York, with 16.6 tons per lane-mile. Under MassDOT salt policy, salt or sodium chloride is applied at 240 pounds per lane-mile. In other words, trucks in Massachusetts are dumping more than a ton of salt every 10 lane-miles in a single application! Salt does not evaporate or otherwise get removed, so one has to ask: what is the fate of all this salt that is dumped on our roads?

Unfortunately, most of it is washed off of roadways by rain runoff and snow melt and enters our rivers and streams or percolates through the soil into our drinking water supplies. That’s the situation that Cambridge, MA has been combating for years. This densely-populated city gets its water from two reservoirs, both located next to Route 128, making it particularly susceptible to salt contamination. Another town suffering from the same issue is Boxford, MA. The town launched a suit against the state highway department, MassHighway, to close its salt storage shed, contending that it was responsible for contaminating at least 30 local wells. Aside from the ecological damage of excess salt, there are also health and financial burdens associated with high salt levels in public and private water supplies. High salt levels can result in skin and eye irritation and pose a danger for individuals with sodium-restricted diets, according to the New England Interstate Water Pollution Control Commission.

MassHighway is already under court order to manage stormwater runoff after CLF’s successful suit in 2008. Hopefully this effort will divert some of the salt from our waters and, in turn, lead to better health for both the environment and the MA residents who live in it.

Today, the U.S. EPA announced that it will join CLF’s lawsuit against the Boston Water and Sewer Commission (BWSC) for violations of the Clean Water Act. The suit, filled by CLF in U.S. District Court in February 2010, states that BWSC has failed to control polluted discharges from its storm water system, allowing it to carry raw sewage and excessive levels of bacterial, copper and zinc into Boston’s waterways, threatening the health and well-being of the surrounding communities.

BOSTON, MA  December 22, 2010 – The Conservation Law Foundation (CLF) has issued the following statement in response to the motion filed today by the U.S. Environmental Protection Agency (EPA) stating that it will join CLF’s lawsuit against the Boston Water and Sewer Commission (BWSC) for violations of the Clean Water Act:

“The complaint against the Boston Water and Sewer Commission documents serious failures in the system that are allowing ongoing unlawful pollution of Boston’s waterways, including the Charles, Mystic and Neponset Rivers, in some the city’s most economically-challenged communities,” said Christopher Kilian, director of CLF’s Clean Water and Healthy Forests program. “The federal government’s entry into this case is a clear indication of the urgency of the matter and the priority EPA places on it. BWSC’s inability to maintain a system that ensures clean water is a violation of the law and an affront to the people of Boston. The United States agrees with CLF that BWSC must make a major commitment now to improve water quality, as other cities have done, and restore these resources to health for everyone’s benefit.” More>>

In an effort to clean up the Charles River—and as the result of years of CLF advocacy—residents in Bellingham, Franklin, and Milford, MA may soon be obligated to comply with a proposed EPA mandate to reduce phosphorus runoff by 65 percent. As with most important initiatives to restore our environment, implementing this program will cost money, and there are constituencies opposed.  This Milford Daily News article chronicles some of the factors at stake and how residents have reacted to the news.

What’s most exciting about the public dialogue is to see that the discussions have advanced to real thinking about HOW to finance cleanups through stormwater utilities and other fee structures for reducing polluted runoff.  In Massachusetts, polluted runoff is the number one cause of water pollution.  Conversations about how to secure dedicated funding to solve the problem have generally only happened in a few communities under enforcement orders. They had to sort out issues of what’s fair, what’s practical, and what’s most palatable to residents in order to finance the fixes.  Now we’re seeing similar discussions in more communities where new stormwater regulations are proposed. These communities can serve as a model of forward-thinking investment in the clean waters that are critical to a thriving New England.

The Massachusetts’ Water Resource Authority’s decision to release 15 million gallons of untreated sewage into Boston Harbor’s Quincy Bay during last weekend’s storm felt to many like a giant step backward in the decades-long fight to clean up Boston Harbor. The good news is that there are actions that can be taken today that could have kept MWRA officials from having to make that decision in the future—implementing green stormwater infrastructure to reduce the burden on our sewer pipes, reduce flooding and make communities more resilient to climate change.

Many of our state’s aging sewer systems become overwhelmed with a mix of rainwater and sewage during large storms. That’s why MWRA officials were stuck between a rock and a hard place, forced to choose between quietly releasing 15 million gallons of untreated sewage into Quincy Bay or letting the water flood the station and release that sewage into basements, but sparing the Harbor. The problem runs deeper than this one incident—during last week’s storm, there were equally damaging releases of raw sewage into neighborhoods and into the Mystic and Charles Rivers as well. (See video footage here).

Massachusetts can stop these incidents by investing in green stormwater management techniques to enable communities to better prevent sewer overflows and save money over the long term. Some of these techniques include the use of permeable pavement, green roofs, rain barrels, even gravel—anything that will absorb stormwater and diminish runoff from hard surfaces. These actions can be taken by homeowners in and around their homes, at the city scale by greening streets, parking lots, and alleys, and at the state level, by greening state highways and universities.  Massachusetts residents can urge their towns to adopt bylaws requiring green stormwater and green building techniques to be used in all new construction or infrastructure projects. Cities like Philadelphia, Chicago, and New York are already rolling out these techniques and finding that they are both cost-effective and environmentally sustainable.

Fortunately, we have a chance RIGHT NOW to tell the state of Massachusetts how important it is to us to keep stormwater in check. The U.S. EPA is currently working on a stormwater permit that will govern the stormwater management of communities across Massachusetts for the next five years.

Help Massachusetts prepare for the next storm before it happens. Tell our government that we need a stronger stormwater permit to govern Massachusetts waterways and keep our communities pollution-free.
