Support the City's review of a pre -public notice courtesy copy of Ecology's draft NPDES permit, prior to public notice of the formal Draft Penult, with technical analysis of Ecology's approach. Once Ecology put the permit out for public comment, provide a draft comment letter on the permit and fact sheet for the City's review. Nitrogen Optimization and Management Concept Planning. Ecology's focus on Puget Sound Nitrogen management will result in new planning requirements being included in either individual NPDES permit renewals, or the new Nitrogen General Permit, or both The requirements will include near-teim Optimization Planning and longer -tetra Nitrogen Removal Planning The specifics of these permit requirements are evolving with Ecology. It is important to note that these will be planning requirements, and not implementation requirements The City will be required to develop plans and submit them for review to Ecology. Implementation of changes will be based on many factors, including the limited availability of options for the City to reduce nitrogen in the existing treatment process, as well as many other factors that the City must consider in balancing all of the investments required to comply will all regulatory and performance requirements, maintain City assets, and provide for affordable Compliance Schedules. The purpose of this task is to assist the City in conceptualizing plans that will satisfy Ecology's requirements but also provide the City with avenues to practical, technically feasible, and affordable approaches that can be implemented over time in ways that address the City's priorities. This information will be used to support the City's dialog with Ecology on current and future discharge permitting.
