Today the Department of Ecology issued its draft revisions of the stormwater permits for large and medium-sized cities. The stormwater permits set standards for using green infrastructure (or Low Impact Development) solutions for new development and redevelopment projects in order to prevent stormwater pollution coming from streets and paved development. Collectively, these permits are the primary statewide regulatory tool to protect public waterways, including streams, lakes, rivers and marine waters from polluted runoff.

“These new permits are our biggest chance to make real progress in the restoration of Puget Sound,” said Chris Wilke, Executive Director of Puget Soundkeeper Alliance. “Unfortunately, the current drafts fail to deliver on proven solutions to reduce toxic runoff.”

In 2008, a state hearings board issued a landmark decision in favor of Puget Soundkeeper Alliance requiring that cities and counties around Puget Sound take more aggressive steps to reduce polluted runoff. Urban and suburban areas are required to have a stormwater permit under the federal Clean Water Act, because their storm sewers discharge polluted runoff into creeks, lakes, rivers and marine waters such as Puget Sound. This runoff is now the single largest source of toxic pollution entering Puget Sound, and plays a major role in destroying salmon runs, closing shellfish beds and swimming beaches and contributing to sewage overflows.

Green infrastructure technologies are engineered solutions that slow down and filter polluted runoff by mimicking the filtration provided by natural systems. These techniques have been shown to stop pollution effectively, and at a lower cost than traditional stormwater infrastructure.

“The state has been talking for a long time about how big this pollution problem is. Now is our chance to see some actual results,” said Bruce Wishart, speaking for People for Puget Sound. “We’d like to see developments adopt proven, commonsense building techniques, so we can clean up Puget Sound, reduce flooding risks, while at the same time supporting our green building industries. The current draft versions of the permits simply don’t get us there.”

“We know that when they’re well-designed, Low Impact Development (LID) strategies work.  They slow runoff and improve the quality of water entering receiving bodies like Puget Sound.  They also can provide beautiful amenities that increase property resale values,” said Joel Sisolak, outreach and advocacy director for the Cascadia Green Building Council.

One area of concern is the lack of clear parameters that would prevent a developer from paving over existing green space entirely. The coalition of advocates seeks a balanced ratio of green space to pavement, to prevent excessive polluted runoff from sites that impairs the health of public waterways. This fix would allow development to proceed while preserving effective natural filtration capabilities onsite.

Another opportunity for improvement is to minimize the amount of loopholes that allow developers to continue to use conventional polluting technologies when greener alternatives are available. For example, the new permit drafts allow multiple exemptions from green infrastructure requirements, making it easy for developers to opt out of needed clean water solutions.

Ecology has worked for more than two years with science and policy advisory groups on the municipal stormwater permit redrafting and issuing. People for Puget Sound and Puget Soundkeeper Alliance participated in those advisory groups.

The state has acknowledged that polluted runoff remains the single largest source of toxic pollution for Puget Sound and set a goal for cleaning up Puget Sound by 2020.

The Department of Ecology has started its public comment period to the draft permit, which will run until Feb. 3. Ecology will hold workshops and public hearings starting in December. Members of the public may submit comments online.
