Regulatory improvement at Ecology is about continually improving our regulatory standards and decision-making processes.

Current Spills Rule-Making Activity

Ecology is beginning a new rulemaking for Chapter 173-182 WAC Oil Spill Contingency Plan Rule. The rule requirements were last updated for pipelines in 2006. At that time the pipeline planning standards were developed to align with the marine terminal standards. In Washington pipelines exist in both marine and inland areas. After several years of implementing the rule, we have identified the need to update our standards to ensure that required oil spill response equipment is appropriate for the pipeline risks and operating environments (marine and inland). We also feel the need to better incorporate and embrace available technology and geo-referenced data in our planning requirements.
