ACWA Comments On Revised Definition of “Waters of the United States”
As the agencies proceed with this process to revise WOTUS and work to create a durable rule the states remind the agencies of several foundational principles that must be adhered to. (1) respect the role of the states as co-regulators and provide early, continuous, and meaningful opportunities for dialogue and input as any new rule is developed; (2) respect and follow the science though balanced within the limitations of statute and judicial precedent; (3) recognize the geographic, geologic, climatic, hydrologic, and leadership diversity among states and craft a definition that provides clarity but also flexibility for state implementers; (4) prepare to provide the states, well in advance, with technical assistance, tools, and trainings to assist with implementation of any revised definition; and (5) consider a delayed effective date dependent on the significance and scope of the final rule to give state partners adequate time to revise state regulations and/or to develop new state policy to cover any changes in coverage as a result of the revised jurisdictional definition.
