Publication Summary

The Department of Ecology (Ecology) is proposing a new Chapter 173-565 WAC and amendments to Chapters 173-531A and 173-563 WAC. The purpose of Mainstem Columbia River Water Management Program (Chapter 173-565 WAC) is to implement a state water management program for the Mainstem Columbia River to facilitate water allocation decisions by the state. The purpose of the program is to: • Provide a framework for authorizing new and reliable uses of water from the Columbia mainstem in support of population growth and economic development; and • Reduce the risks to fish by dedicating water to instream uses and releasing such water into the river at times and in ways that maximize the benefits to fish. This Small Business Economic Impact Statement (SBEIS) is provided consistent with the requirements of RCW 19.85, the Regulatory Fairness Act. If the rule has its intended effect, Ecology expects that this proposal will result in benefits to most affected businesses. However, under RCW 19.85 Ecology must review business costs associated with this proposal, regardless of the gain to businesses, to determine whether costs are disproportionately higher for small businesses in comparison to large businesses.
