Balance the Load 

It’s time to move forward with plans to clean up the Spokane River.

A series of meetings began Aug. 23 to discuss how to put into action the water quality improvement plan for the Spokane River and Lake Spokane. Many interests are at the table — community leaders, environmental agency leaders, environmental advocacy groups, representatives of municipalities and industries that discharge wastewater into the Spokane River.

A testament to how important these discussions are for our environment and our economy is the participation by state Department of Ecology Director Ted Sturdevant, U.S. Environmental Protection Agency Region 10 Administrator Dennis McLerran and Idaho Department of Environmental Quality Director Tony Hardesty.

Ecology developed a plan to clean up the river and lake, called the “Spokane River, Lake Spokane Dissolved Oxygen Water Quality Improvement Report.” The EPA approved the plan in May.

The river cleanup plan (known as TMDL, or a Total Maximum Daily Load report) specifies how much pollution each facility may discharge into the river and still protect water quality standards. The plan also takes into account indirect sources of pollution, such as pollution in groundwater and runoff from urban, residential and farmland.

The goal of the river cleanup plan is to improve oxygen levels in the river and lake by reducing pollutants like phosphorus. Too much phosphorus causes algae to grow at excessive rates. When the algae decomposes, it uses up oxygen, robbing fish of the oxygen they need to breathe.

Several stories this summer have reported on concerns coming from cities in Idaho that the plan is unfair because it holds them to stricter pollution discharge limits than Washington and does not allow for growth in Idaho. The city of Post Falls filed a lawsuit against the EPA for approving the plan.

The plan assigns the same monthly average phosphorus limit of 50 parts per billion to each facility; we believe this is fair. Facilities that discharge into the river will need to comply with a March-to-October phosphorus limit. This number varies depending on how often a facility tests its wastewater. In Washington, Inland Empire Paper and Liberty Lake sample less frequently, so we have less confidence in the data. The plan assigns those facilities, plus those in Idaho, with a slightly lower seasonal limit to make up for the lack of data.

The EPA issues water quality permits in Idaho, but the Clean Water Act prohibits the EPA from issuing water quality permits to dischargers in an upstream state that contribute to a violation of water quality standards in a downstream state. That’s why Idaho was an integral part of discussions about Washington’s plan to clean up the river and Lake Spokane.

In the end, there is a maximum amount of pollution the river can accept and continue to be the river we all want it to be. It’s a very small amount to divvy-up, and increasing the amount anyone is allowed means reducing the amount someone else is allowed. We feel that a rebalancing of pollution loads, if appropriate, can be addressed as we implement the plan to clean up the river and the lake.

Many of the concerns raised by Idaho dischargers will be addressed as the plan is implemented over the next 10 years. Different types of adjustments can be made along the way to help facilities meet their new limits. For example, Ecology and the EPA are working on guidelines to give facilities credit toward meeting their discharge limits by reducing pollution from off-site sources when that makes economic sense. This “trading” of credits could be allowed under some circumstances — as long as the net effect gets us where we need to be — in compliance with state and federal standards.

Ecology stands behind the river cleanup plan.

It is technically sound, reasonable and fair to all that discharge into the river, whether they are in Idaho or Washington. We will continue to work towards putting the plan in action. The sooner we begin, the sooner we’ll see a river and a lake with cleaner, clearer water. That’s where we need to direct our energy — not toward litigation.

Kelly Susewind is the water quality program manager for the Washington State Department of Ecology.
