These rules are contained in Chapter 220-660 WAC and become effective July 1, 2015. They replace the old rules found in Chapter 220-110 WAC. Prior to these changes, the last comprehensive update to these rules was in 1994. The new rules establish new standards for HPAs, which set the conditions for specific projects in state waters.
Most HPA permittees will not notice any significant changes in how they apply for HPAs, or the requirements imposed in the HPA on how they conduct their project. Most of the rule changes reflect how WDFW already was processing HPA applications based on current science. The old rules simply had not caught up with where WDFW was in processing applications.
Any HPAs issued to you under the old rules will still be valid and can be used to conduct hydraulic projects. If, however, you need to modify or renew those HPAs, the new rules would apply and a new HPA would reflect those requirements.
