Short Description

The Washington State Department of Ecology is revising the state′s Underground Injection Control (UIC) Program rule, chapter 173-218WAC and the State Waste Discharge Permit Program rule, chapter 173-216WAC. The goal of the UIC Program is to protect ground water by regulating the disposal of fluids into a UIC well. The reason the regulation was open for revision was because the U. S. Environmental Protection Agency (EPA) completed revisions to the federal UIC program in 1999. Washington′s UIC regulation needed to be revised to be consistent with the new federal regulations and to allow Ecology to continue to administer the UIC Program. The federal revisions were added to the regulation. Other revisions were also made to clarify the types of UIC wells allowed in Washington, the types of fluids allowed in UIC wells, and more detail on the best management practices required to protect ground water quality.

Abstract Long Description

The Washington State Department of Ecology is revising the state′s Underground Injection Control (UIC) Program rule, chapter 173-218WAC and the State Waste Discharge Permit Program rule, chapter 173-216WAC. The goal of the UIC Program is to protect ground water by regulating the disposal of fluids into a UIC well. The reason the regulation was open for revision was because the U. S. Environmental Protection Agency (EPA) completed revisions to the federal UIC program in 1999. Washington′s UIC regulation needed to be revised to be consistent with the new federal regulations and to allow Ecology to continue to administer the UIC Program. The federal revisions were added to the regulation. Other revisions were also made to clarify the types of UIC wells allowed in Washington, the types of fluids allowed in UIC wells, and more detail on the best management practices required to protect ground water quality.

The majority of UIC wells in Washington are used to manage stormwater. Staff working on the rule revisions worked closely with Ecology′s stormwater program staff to incorporate the ground water protection best management practices from the stormwater program into the UIC regulation.

One change was made to Chapter 173-216 WAC to allow UIC wells in a state waste discharge permit.
