Following the comprehensive plan amendment, the TCAAP Redevelopment Code (TRC) and TCAAP Regulating Plan were updated with the following zoning changes: • 12.9 acres rezoned from NR-4 to NR-3 • 21 acres rezoned from Flex Office to NR-3 • 11.4 acres rezoned from Flex Office to NR-4 The TRC Ordinance amendment to reflect the rezoning was approved on January 8, 2024, and the updated Regulating Plan is included in Attachment A. Both development scenarios would be compatible with the future land uses identified in the 2040 Comprehensive Plan and with the TRC. No mitigation measures are necessary. 4.2.3. Water Resources Wetlands 9P In the 2014 AUAR, 14.4 acres of wetland were identified within the study area. All 14.4 acres were assumed to be jurisdictional. Later in 2014, the US Army Corps of Engineers (USACE) issued an Approved Jurisdictional Determination (AJD) for the site, concluding that only three wetlands within the site are regulated by the USACE. The Rice Creek Watershed District (RCWD) also provided a notice of determination (NOD) under the state Wetland Conservation Act. The AJD and NOD have been extended since the 2019 AUAR: the AJD expires in January 2025 and the NOD expires in November 2025. Permits to be obtained from the USACE and RCWD are included in Table 6. No additional mitigation measures are needed based on this updated information. 4.2.4. Contamination/Hazardous Materials/Solid Wastes On September 23, 2019, the soil and surface water at the TCAAP site were removed from the federal Superfund list (National Priorities List). The TCAAP soil and surface water were removed from the state Superfund list (Permanent List of Priorities) on April 22, 2020. The US Army's cleanup efforts under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) are ongoing, however. Historical releases of hazardous substances from the former TCAAP site into Round Lake, located south of the AUAR study area, resulted in sediment contamination in the lake. An evaluation of impacts to Round Lake sediment concluded in 2021, and a Record of Decision (ROD) for the Proposed Plan for cleanup at Round Lake was finalized in 2022. The US Army is responsible for these cleanup activities. Within the TCAAP site, the US Army also completed optimization of the TCAAP Groundwater Recovery System in 2022.4 In 2023, the US Army completed a preliminary assessment and site inspection on the current or potential historical use of per- and polyfluoroalkyl substances (PFAS) at the TCAAP site in accordance with CERCLA, the National Oil and Hazardous Substances Pollution Contingency Plan, and Army/Department of Defense policy and guidance. PFAS was 4 Additional information on remediation of the broader TCAAP site is available at https://webapp.pca.state.mn.us/cleanup/search/superfund?site Id=47112-AREA0000000014 and https://vvww.tcaar)rab.ora/ TCAAP AUAR Update 8 April 2024
