Attachment SC <br /> G3. Parcel Selection Meeting: Meet with City staff to present and review the available land parcels. <br /> Determine up to three (3) parcels for more critical feasibility study. <br /> G4. Review Receiving Stream Permitting Considerations: Using available data where applicable from <br /> previous WWTP siting evaluation, assess Texas Surface Water Quality Standards forthe San Marcos <br /> River and the TCEQ's Integrated Report to determine potential effluent limits. Consult TCEQ's Total <br /> Dissolved Solids (TDS) screening tool to evaluate TDS effluent limits necessary to maintain water <br /> quality standards. Based on this evaluation and FNI's knowledge of regulatory trends, establish an <br /> assumed discharge limit set for each site for us in subsequent WWTP evaluation tasks <br /> G5. Conceptual Sizing of WWTPs: Perform a high-level conceptual design for the WWTPs using logical <br /> incremental expansions to define the required unit processes, capacities and physical dimensions <br /> for the facility sized for the buildout capacity.A generalized site plan will be developed for each site <br /> based on build-out capacity. Conceptual level cost estimates for the initial phase of the generalized <br /> treatment process will be developed using planning level,capital cost estimating methodology. <br /> G6. High Level Assessment of Proposed WWTP Site:Perform a brief suitability(fatal flaw)analysis of the <br /> selected WWTP sites proposed by considering engineering and environmental constraints, <br /> including: <br /> • Compatibility with existing land use plan <br /> • Wastewater(watershed)service area(s) <br /> • Proximity to flood plain <br /> • TPDES Discharge Permit limits and general assessment of potential for obtaining a <br /> discharge permit <br /> • Terrain (2 to 5%slope preferred) <br /> • Proximity to near and long-term development and buffer zone requirement <br /> • Presence of federally-listed species habitat, including Federally-Designated Critical <br /> Habitat,subject to Endangered Species Act regulations <br /> • Presence of federally-regulated waters,subject to US Army Corps of Engineers jurisdiction <br /> and permit requirements <br /> • Presence of previously-recorded cultural resources (e.g., historic structures or <br /> archeological sites) <br /> • Conveyance infrastructure requirements compared to conveyance to the existing WWTP. <br /> • Site access <br /> • Access to electrical power supply <br /> • Geological and soil assessment(impacts on construction costs) <br /> G7. Progress Meeting #5: Attend and facilitate a meeting with City to review wastewater treatment <br /> plant siting evaluation. <br /> G8. WWTP Siting Evaluation Technical Memorandum: Prepare a Technical Memorandum detailing the <br /> wastewater treatment plant siting and feasibility analysis. An electronic PDF file of the Technical <br /> Memorandum will be submitted to the City. Comments or edits to the memorandum will be <br /> incorporated into the Master Plan report. <br /> Page 6 of 8 <br />
