MEMORANDUM TO: Linda Guerrero, Chair, Environmental Commission FROM: Pamela Abee-Taulli, Environmental Review, DSD DATE: October 21, 2020 SUBJECT: Albert H. Ullrich Water Treatment Plant, Revision 2 Variances Dear Chair Guerrero, Ullrich Water Treatment Plant, operated by Austin Water Utility, is critical to providing the City with safe drinking water. The site plan under review is a revision to the original site plan, which was approved in 2003. The plan includes multiple projects and will require seven Environmental variances, largely due to the site’s location in an environmentally sensitive area with numerous environmental constraints. Because of the unusually high number of variances, I have taken the uncommon step of providing a single set of findings for all the variances, rather than one set of findings for each variance. Additionally, I am including this memo to introduce the list of proposed projects. The overall purpose of the plan revision under review is to improve operator and environmental safety by eliminating potential hazards and to upgrade miscellaneous plant processes to ensure the plant can reliably deliver drinking water. The sludge change-over structure replaces existing structures that require confined space entry. Other improvements provide safety washdown areas and a looped, potable water supply to the facility. The spill containment structure will contain fugitive spills that may enter the existing storm drain system from chemical delivery areas and will prevent their discharge into Little Bee Creek. The Low Service Pump Station Electrical Feed Renewal project includes construction of a new electrical building, retaining walls, electrical and mechanical equipment, parking areas, access road, and duct bank routing. Thank you for your consideration.

Via Electronic Filing Founded by Congress, Republic of Texas, 1839 Watershed Protection Department P.O. Box 1088, Austin, Texas 78767 May 20, 2019 Ms. Bridget C. Bohac Office of the Chief Clerk (MC-105) Texas Commission on Environmental Quality (TCEQ) RE: City of Austin Comments on Application No. WQ0015594001 (Sawyer-Cleveland) Dear Ms. Bohac: I write to provide supplementary comments on the Sawyer-Cleveland Partnership application for a Texas Pollutant Discharge Elimination System Permit (No. WQ0015594001). The application requests approval for a discharge up to 92,000 gallons per day to the Long Branch Tributary of Barton Creek. The City of Austin hopes that TCEQ staff will consider and utilize these comments during the technical review of the proposed permit application. The City reserves the right to amend and supplement these comments. As it concerns this permit application, the City of Austin (“City”) is an affected party. The City requests, as an affected party, notice of subsequent correspondence, proceedings, draft permits, or contested case hearings on this permit. Barton Creek provides recharge to the Edwards Aquifer. Barton Creek currently exceeds fishable/swimmable quality. One of the City’s interests is to prevent degradation of the water quality of Barton Creek and the Barton Springs Segment of the Edwards Aquifer. The City holds a 1,675.7 acre conservation easement in the Barton Creek Watershed downstream of the proposed discharge location, purchased in 1999 using $5,864,950 in voter-approved bond funding. This property has been preserved in perpetuity to protect the integrity of Barton Creek and regional groundwater resources. Additionally, the City is a participant in the Texas Clean Rivers Program and provides water quality monitoring data from Barton Creek to the TCEQ. Attached please find water quality modeling performed by the City of the proposed discharge permit application. The City utilized a Water Quality Analysis Simulation Program (WASP) model to evaluate the water quality impacts of proposed discharge on the Long Branch Tributary to Barton Creek, including the detention ponds within the route of the proposed discharge in the Polo Club neighborhood northeast of the intersection of Polo Club Drive and Pemberton Way (Richter 2018). The WASP modeling predicts that total nitrogen and total phosphorus concentrations downstream of the detention ponds in the Long Branch Tributary will be similar to concentrations exiting the proposed wastewater treatment plant during the majority of the year, and phytoplankton chlorophyll concentrations will be hypereutrophic during algal blooms. a The City of Austin is committed …
Water Quality Impacts from a Proposed Wastewater Discharge to Barton Creek ABEL PORRAS, PE ENVIRONMENTAL RESOURCE MANAGEMENT DIVISION WATERSHED PROTECTION DEPARTMENT OCT 21, 2020 The Proposed TPDES Permit The Sawyer-Cleveland Partnership applied for a TPDES permit The permit would allow treated wastewater effluent to be discharged to a tributary of Barton Creek in the Contributing Zone of the Barton Springs Segment of the Edwards Aquifer Environmental Resource Management Division has modeled this discharge and assessed its impact on the water quality in Barton Creek. The Location of the Discharge The Location of the Discharge The Location of the Discharge The Proposed TPDES Permit The Sawyer-Cleveland Partnership are proposing that their permit: Would authorize a discharge of treated wastewater not to exceed a daily average flow of 92,000 gallons/day; Estimated effluent concentrations of ~22mg/L of Nitrogen and ~4 mg/L of Phosphorus Dripping Springs TPDES permit allowed discharge of treated wastewater not to exceed a daily average flow of 995,000 gallons/day Estimated effluent concentrations of ~6mg/L of Nitrogen and ~0.5 mg/L of Phosphorus The Model We’re interested mostly in the impact on the stream from algae due to N and P. Algae changes the trophic status (or the clarity of the stream).

Within six months from Council approval of an ordinance, develop best management practices for the WUI Code that shall be added to the City’s technical manual through the rules process. Include the public in several working group meetings prior to the standard rules meeting. AFD has begun drafting rules and will include public where appropriate. Timing is contingent on City rules adoption schedule. Emergency rules are expected to be used on January 1, 2021 while permanent rules are adopted with the Development Services Department rules adoption schedule for Quarter 1. 2. Establish a proactive Firewise process where AFD assesses the fire risk on site for new construction or remodels, prior to doing any tree or vegetation work in defensible space. Do not allow tree or vegetation removal to create defensible space or creation of shaded fuel breaks without prior AFD Firewise assessment. AFD will consider this process during administrative rules development. Existing regulations for vegetation clearing and tree removal will apply. 3. Require hardening new or remodeled buildings and structures before removing trees or vegetation in the defensible space. AFD adopted this approach with support from stakeholders including the Environmental Commission. pg. 1 10/07/2020 WUI Code Environmental Commission Conditions 4.

WUI Code Defensible Space Rule Overview Section 601 rule describes how fire protection requirements, mainly defensible space, could be required: 101.2, Scope, allows use or occupancy to continue if it was legal at time of adoption of the code and does not constitute a distinct hazard. o Code official can require fire protection requirements, including defensible space, for illegal use or distinct hazard. o Distinct hazard also linked by definition to table 502.1, Fire Hazard Severity, and Appendix C, Fire Hazard Severity Form. 101.4, Retroactivity, says code applies to conditions arising on and after the effective date. 107.2.1, Permits Required, describes conditions that would not allow a permit to be issued. A property owner would therefor need to correct at least one of the conditions to be able to obtain a permit; reduce hazard severity, or provide conforming access, water supply or defensible space. o o If defensible space is chosen then Chapter 6 requirements would apply. If reduction of fire hazard severity is chosen then either a vegetation management plan per 502.2 could be provided or Appendix C could be used to reduce the rating score to below 75. Chapter 6 requirements would apply to both a vegetation management plan as well as the defensible space component of Appendix C if it is used to reduce points. 401.3 references general safety precautions and triggers Appendix A by direct reference. Appendix A covers things that are mostly covered by other City regulations but gives the Fire Marshall added authority for certain activities and uses including provision of defensible space: o Vegetation control for Roadways, 10’ clear either side Electrical transmission and distribution lines o Obstruction of access or defensible space o Clearance requirements for ignition source control o Storage of hazardous materials o Protection of pumps and water supply storage facilities o Land use limitations for temporary uses Section 603, Defensible Space and 604, Maintenance of defensible space: When required or allowed shall be not less than 30’ or to property line and may be increased or decreased by the Fire Marshall based on site specific analysis. Fuel modification distances in table 603.2 are available for increases or decreases but not directly linked since table 503.1 for ignition resistant construction was deleted. Deletion of table 503.1 means defensible space would not be an option to avoid ignition resistant construction. Defensible space …
