Draft dissolved oxygen modeling scenarios updated

From: Laurie Mann

Spokane River Stakeholders,

The attached document contains the updated list of the draft modeling scenarios currently being considered by Ecology, IDEQ, the Spokane Tribe and EPA for assessment of Lake Spokane dissolved oxygen impacts.

These scenarios are being designed to provide quantitative “building block” information that will inform the TMDL and NPDES permitting process. Depending on the information gained from this first round of modeling scenarios, additional scenarios may be developed with your input.

Input will be taken on these scenarios at the February 27th stakeholder meeting. Contact Laurie Mann with comments or questions.

Also attached is the memo outlining policy issues currently considered as part of the “Dual Assessment Point” scenario.
