~D Rule .0265, Stormwater Management for New Development This rule would require ail local governments in the Jordan watershed to develop and implement programs to require Stormwater controls on new development activities to meet subwatershed nutrient loading rate targets. Developers would control nutrient export to minimum levels onsite, and could meet remaining reduction needs through in-lieu fee payment to EEP, or to local governments with aDivision-approved local offset plan. Control of flows for stream protection would also be required. Development in existing water supply watersheds would also be required to comply with density-related treatment thresholds and density caps designed to protect local water supplies where they are more stringent. Within one year of effective date, the Division would submit a model local program to the Commission for approval. Within another six months, local governments would submit programs for Division review and subsequent Commission approval. Within two and a half years after the effective date, local programs would be implemented. Annual reports would be required. • Includes acreage thresholds for new development (Item (3)). • Incorporates nonpoint source loading rate targets to make them specific to this rule and consistent with methods used to date, and includes clarifying explanatory language that may allow refinements during implementation. • Includes offsite loading rate thresholds for consistency with other programs, to provide for reasonable onsite measures, and to avoid overtaxing EEP. • Includes offsite options. • Incorporates BMP design criteria, including water supply requirements that remain applicable. Rule .0266, Stormwater Management for Existing Development This rule would require all local governments to implement loading reduction measures on existing developed lands toward long-term load reduction targets for those lands. They would conduct feasibility studies, and then submit program proposals for Division and Commission approval within three years after effective date. Programs would propose implementation rate, nature and overall timeframes envisioned. Programs would be implemented within four years of rule effective date. Programs for public education and illegal discharge detection and elimination are to be implemented within two and a half years. Annual reports would be required. • Counties would be subject. • Explicitly credits BMPs implemented post-baseline as reductions • Explicitly counts load increases from post-baseline development in reduction needs. • Includes explanation of types of activities that could be credited as load-reducing. • Includes criteria for content of local program submittals to provide an understanding of expecfiations.
