Declaration of policy It is declared that, because safe and high-quality drinking water is a precious resource,the general welfare requires that the water resources available to the city be put to the maximum beneficial use, and that the waste or unreasonable use of water be prevented, and the conservation of water is to be encouraged with a view to its reasonable and beneficial use in the interests of the people of the city and for the public health, safety and welfare.The city council has determined that an aggressive water conservation and drought contingency program will protect the integrity of water supply facilities, prolong the life of existing water sources, and minimize the impacts of water supply shortages, and therefore adopts the following regulations and restrictions on the delivery and consumption of water. Water uses regulated or prohibited under this plan are considered nonessential and continuation of such uses during time of water shortage or other emergency water supply conditions are deemed to constitute a waste of water which may subject the offender to penalties. The city council has also determined that it is its policy that water customers are encouraged to voluntarily limit the use of water for nonessential purposes and to practice water conservation. Dedicatory instruments may not impose rules that contradict this plan, nor require the use of more water when customers are being asked to reduce. 2. Public Involvement and Education Opportunity for the public to provide input into the continued development of the drought contingency plan, or any modifications, is accepted by attending City Council meetings, held the second and fourth Thursday of each month or contacting City water conservation staff. The city will provide the public with information about water use, including information about the conditions under which each Stage of this article is to be initiated or terminated and the drought response measures to be implemented in each Stage. Drought and water conservation information will be provided by public meetings, press releases, utility bill inserts, the city's website, electronic media notification, and/or direct mailouts or emails. 3. Coordination with Regional Water Planning Groups The service area of the City of Round Rock is located with the G Regional Water Planning Area. City of Round Rock will provide a copy of this Plan to the Region G group, along with our wholesale water suppliers: the Brazos River Authority, and the Lower Colorado River Authority. 4. Wholesale providers The city contracts for raw water in Lake Georgetown and Lake Stillhouse Hollow from the Brazos River Authority and Lake Travis from the Lower Colorado River Authority and the Brazos River Authority.The city will comply with and implement any drought contingency requirements that may be set forth in any contracts with these river authorities. Because of the diverse water sources Round Rock utilizes, the city may opt to reduce consumption from one source to meet the requirements of a provider, rather than enact a drought stage. 5. Wholesale customers Page 2 of 20 The city sells wholesales water to eleven MUDs. These are Aqua Tex, Fern Bluff, Paloma Lake MUD 1 & 21 Williamson County MUD 10 & 11, Vista Oaks, Walsh Ranch, Round Rock Ranch PUD, Blessing Mobile Home Park, and Tera Vista. (a)All wholesale water contracts require compliance with the city's drought contingency and water conservation plans. Each contract specifies that the water supplied to the wholesale customer may be reasonably limited by the city on the same basis and to the same extent as the supply of water to any other customers within the city. (b) All wholesale contracts entered into, renewed or extended after the adoption of this plan will include provisions for distributing water to the wholesale customer in accordance with V.T.C.A., Water Code § 11.039. 6. Implementation and Authorization The city manager is hereby authorized and directed to implement the applicable conservation Stages upon his determination that the implementation is necessary to protect the public health, safety and welfare.The city manager shall have the authority to initiate or terminate drought or other water supply emergency response measures as described in this article. 7. Application The provisions of this article shall apply to all persons, customers, and owners of property who use or allow the use of city water, wherever situated.The terms person and customer, as used in this article, include individuals, corporations, partnerships, associations and all other legal entities.

[Note: this includes Old Settlers parks fields, all ISD sports fields,YMCA fields, and the youth soccer field near Success HS] 13. Stage I Reduction Target Stage I restrictions are intended to achieve a 10 percent reduction in daily water consumption. Page 8 of 20 The formula for determining our reduction goal is calculated by taking the previous three year's same month average use and calculating the % reduction. For example, if reductions in July 2024 were necessary, average monthly use from each of July 2021, 2022, and 2023 use would be averaged together, and the 10% reduction goal taken from that average. 14. Stage II Triggers (a) Stage II shall be implemented when any of the following triggers occur: (1) Supply-based trigger for implementation of Stage II is as follows: a. Lake Georgetown Reservoir elevation is below 770 feet above mean sea level (msl) for three consecutive days or b.

The formula for determining our reduction goal is calculated by taking the previous three year's same month average use and calculating the % reduction. For example, if reductions in July 2024 were necessary, average monthly use from each of July 2021, 2022, and 2023 use would be averaged together, and the 30% reduction goal taken from that average. 21. Pro-Rata Curtailment In the event of historical drought, or dire emergency,the city's water suppliers may enact pro-rata curtailment. Those triggers are outlined below: (a) BRA DCP Stage IV trigger: (1) combined storage drops below 92,986 acre-feet (2)As deemed appropriate by the BRA due to disruption in WCRWWL pumping operations. (b) LCRA DCP Stage IV trigger: (1) combined storage drops below 600,000 acre-feet (2) LCRA Board declares "Drought Worse Than Drought of Record" Page 15 of 20 (3) 20% mandatory pro rata curtailment for firm customers (4) Prohibition on irrigation of ornamental turf, may allow handheld hose watering of foundations,trees, and vegetable gardens (5) Reduction target of 30% (c) Termination of Stage IV (1) BRA may terminate Stage IV when any of the reasons for initiation have ceased to exist for a period of 60 consecutive days or other relevant factors determined by the BRA. Upon termination of Stage IV, Stage I-III may become operative depending on conditions at the time. (2) LCRA Board sets criteria to exit Stage IV, or increase mandatory pro rata curtailment percentage if conditions worsen 22. Powers of the city manager In the event of unusual operational events, catastrophic occurrences, severe weather events, or other public emergencies,the city manager may implement mandatory water restrictions in addition to those set out in this article.The city manager may implement these mandatory restrictions by public announcement and the restrictions are effective immediately upon the making of such public announcement.The implementation of additional restrictions pursuant to this section 44-236 shall expire 15 days thereafter unless the city council adopts a resolution ratifying such determination and implementation within such 15-day period. 23. Procedures for the implementation and termination of mandatory restrictions. (a) Stages I, II, and III may be implemented or terminated at any time by resolution adopted by the city council. (b) When the triggers for implementation of Stages I, II, and III are met,the city manager shall implement the respective mandatory restrictions by issuing a written public announcement stating at a minimum the following information: (1) The date restrictions will begin; and (2) The circumstances and/or reasons that triggered the restrictions. (c) Notice of the implementation and termination of mandatory restrictions will be given through press releases, cable television announcements, postings in public areas, on the city's web page and/or other electronic means.The notifications for implementation will contain, at a minimum, the following information: (1) The date restrictions will begin; (2) The circumstances that triggered the restrictions; (3) The Stages of response and explanation of the restrictions to be implemented; (4) An explanation of the consequences for violations. Page 16 of 20 (d) When the triggers for implementation of Stages I, II, and III are no longer in effect, or the city manager determines that it is in the best interest of the city to terminate the restrictions, the city manager may do so by issuing a written order terminating the restrictions. This termination notice will be promoted on the city's website, customer portal, and other social media outlets. 24. Variance;alternative compliance (a) The director may grant any customer a temporary variance from the restrictions when failure to grant such variance would cause an emergency condition adversely affecting the public health, welfare or safety, and if one of the following conditions is met: (1) Compliance with this article cannot be technically accomplished during the duration of the water supply shortage or other condition for which the restrictions in effect; or (2) Alternative methods can be implemented which will achieve the same or better level of reduction in water use. (b) The director shall inform the customer in writing concerning the granting or denial of such variance and any conditions that may accompany such variance, including any timetables for compliance with the restrictions.The city will treat all customers equally concerning variances, and shall not discriminate in granting variances. No variance shall be retroactive or otherwise justify any violation of restrictions occurring prior to the issuance of the variance. (c) Customers requesting a variance shall file a petition for variance with the director.All petitions shall include the following information: (1) Name, address and contact information of the petitioner; (2) Purpose of water use; (3) Specific provisions of the restrictions from which the petition is requesting relief; (4) Detailed statement as to how the specific restriction(s) adversely affects the petitioner or what damage or harm will occur to the petitioner or others if petitioner complies with the restriction(s); (5) Description of the relief requested; (6) Period of time for which the variance is sought; (7) Alternative water use restrictions or other measures the petitioner is taking or proposes to take to meet the intent of this article and the compliance date; (8) Other pertinent information.

Declaration of Policy, Purpose, and Intent In order to conserve the available water supply and/or protect the integrity of the Brazos River Authority (BRA)water supply system, the BRA adopts this Drought Contingency Plan (Plan). The BRA water supply system includes eleven (11) reservoirs: Lakes Possum Kingdom, Granbury, Limestone, Whitney, Belton, Proctor, Somerville, Stillhouse Hollow, Granger, Georgetown and Aquilla, the Williamson County Regional Raw Water Line (WCRRWL) connecting Lake Stillhouse Hollow to Lake Georgetown, and the East Williamson County Regional Water System (EWCRWS) - Public Water System Identification Number: 2460155. The Plan is developed in conformance with the rules governing drought contingency plans for wholesale water providers set forth by the Texas Commission on Environmental Quality (TCEQ) in Texas Administrative Code Title 30, Part 1, Rule § 288.22, Drought Contingency Plans for Wholesale Water Suppliers. Appendix A includes a copy of the TCEQ rules governing drought contingency plans for wholesale water providers. This Plan, dated May 20, 2024, supersedes the previous Plan dated April 29, 2019. Any reference to statutes, rules and/or regulations in this Plan shall mean and be a reference to such statutes, rules and/or regulations as written on the effective date of this Plan or as they are subsequently amended, modified or restated from time to time. In the event any provision or part of this Plan is found to be inconsistent with applicable statutes, rules and/or regulations, that particular provision or part will be deemed inoperative. 2. Provisions to Actively Inform the Public and Provide Opportunity for Input The BRA has taken the following steps to actively inform the public and affirmatively provide an opportunity for public input in the preparation of the Plan's adoption and to inform wholesale customers about the Plan: • Placing a draft of the Plan on the BRA's website at www.brazos.org and inviting comments on the draft Plan. • Sending a letter to all wholesale water customers and Regional Water Planning Groups detailing updates to the draft Plan, directing them to where the draft could be found on the BRA's website, offering hard copies to those who did not wish to access the draft Plan on the website, and soliciting comments (Appendix B includes a copy of the letter sent to wholesale customers and Appendix C includes a copy of the letter sent to Regional Water Planning Groups). • Providing written notice to the public concerning the draft Plan and inviting their comments (written notice is provided by posting with the Secretary of State's office and on the BRA official website). 3. Coordination with Regional Water Planning Groups The BRA has a statutory responsibility for conserving and developing the water resources of the Brazos River Basin in Texas and making such resources available for beneficial use. The Brazos River Basin covers approximately 47,000 square miles, with 44,440 square miles in Texas (all or part of 70 counties) and slightly over 2,500 in New Mexico. The BRA's service area encompasses the enitre Brazos River Basin in Texas. The BRA also supplies water outside of the Brazos River Basin to the San Jacinto-Brazos Coastal Basin and a small part of the Trinity Basin. Brazos River Authority Drought Contingency Plan TEXT May 2024 Page 1 of 14 The BRA has directed each of the Regional Water Planning Groups located within its service area (Region B, Region C, Region F, Region G, Region H, Region K, and Region 0) to the draft Plan located on the BRA official website. Appendix C includes an example of the letter sent to the Regional Water Planning Groups. 4. Information to be Monitored and Criteria for the Initiation and Termination of Drought Response Stages The BRA's General Manager/Chief Executive Officer (GM/CEO) or designee shall monitor water supply and demand conditions. The triggering criteria described below are based on hydrologic analyses and reservoir operations experience, including lessons learned from previous droughts. Individual lake elevation triggers apply to Lakes Aquilla, Belton, Granger, Limestone, Proctor, and Somerville. For the Lake Possum Kingdom-Granbury-Whitney sub-system, the Lake Stillhouse Hollow-Georgetown sub-system, and the BRA water supply system of all eleven (11) reservoirs, drought stage trigger levels are based on their respective combined volumes. Additional triggers associated with the Palmer Hydrologic Drought Index (PHDI) apply to all reservoirs individually, and the transfer of water from Lake Stillhouse Hollow to Lake Georgetown apply to Lake Georgetown. Reservoir levels are continuously monitored by the BRA. The BRA, its customers, and other interested parties are all responsible for determining when lake levels approach important elevations associated with specific water supply intake structures. A table of critical elevations for customer water supply intake structures is contained in Appendix D. The BRA also monitors the seasonal rainfall forecasts provided by the Texas Water Development Board (TWDB), and uses such forecasts as an informational source for developing drought conditions. The forecasts are issued from January through the end of April and are located at the following website: https://waterdatafortexas.org/dight/rainfall-forecast. Four levels of drought severity, as shown in Table 1, have been identified at which specific actions will be conducted. Each of the four levels include recommendations for specific drought response actions that may be tailored to conditions as they exist at the time. Details on each of the four drought stages are also discussed. Elevation-Capacity Tables based on estimated 2030 sedimentation conditions are contained in Appendix E. House Bill 1437, passed by the Texas Legislature in 1999, allows the BRA to contract with the Lower Colorado River Authority (LCRA) for up to 25,000 acre-feet of water from the Colorado River Basin (LCRA water) for use in Williamson County. For the LCRA water, drought stage trigger levels are based on the combined conservation storage of Lakes Buchanan and Travis, as stipulated in the LCRA Firm Customer Drought Contingency Plan (LCRA Plan), as contained in Appendix F of LCRA's Water Management Plan dated May 20, 2015. The BRA will comply with the LCRA Plan for water used under the LCRA contract. LCRA wholesale customers, including each successive wholesale customers shall be required to develop and implement a drought contingency plan using the applicable elements in the LCRA Rules. Such plan is required to be in compliance with LCRA's rules and regulations for customer drought contingency plans. See Appendix H for more details regarding LCRA's Plan. The BRA also owns and operates the EWCRWS adjacent to Lake Granger, which supplies wholesale treated water. Customers of the EWCRWS include the City of Taylor, Jonah Water Special Utility District, and Lone Star Regional Water Authority. Criteria specific for initiation and termination of Drought Stages of the EWCRWS are contained within this Plan.

Triggers were derived using a water availability tool specifically developed to simulate the BRA water supply system. 2. Elevation-Capacity Tables are contained in Appendix E. 3. In deriving the triggers, balancing factors established in the Possum Kingdom-Granbury Water Management Study were incorporated. 4. Surface elevation and reservoir drawdown are not applicable because reservoirs are operated as a system. Their combined storage is a better drought indicator than individual elevations because elevations in each reservoir can be influenced by other reservoirs within the system. For example,water can be transferred from Lake Stillhouse Hollow to Lake Georgetown through a pipeline that connects the two lakes. Stillhouse Hollow could be completely full while Lake Georgetown was 15 feet low, or Georgetown could be completely full with Stillhouse Hollow being 2.5 feet low, and in both cases, the collective capacity of the reservoirs is 94% full. Using combined storage instead of individual reservoir elevations for the trigger levels allows the operation of the pipeline to be taken into account. 5. Storages shown are for the combined conservation pool storage volume of Lakes Possum Kingdom, Granbury, and Whitney; BRA storage in Lake Whitney is limited to 51,987 acre-feet. 6. Storages shown are for the combined conservation pool storage volume of Lakes Stillhouse Hollow and Georgetown.

Procedures to be Followed for Initiation and Termination of Drought Response Stages Initiation of a Drought Response Stage The BRA's GM/CEO or his/her designee may order the implementation of a Drought Response Stage when the trigger conditions for that stage are met. The following actions will be taken when a drought stage is initiated: The public will be notified through the appropriate media and the BRA Web site. Potentially impacted customers will be notified by telephone with a follow-up letter or e- mail. Meetings will be held with customers as appropriate. The Executive Director of the TCEQ will be notified within five (5) business days. Brazos River Authority Drought Contingency Plan TEXT May 2024 Page 8 of 14 • For LCRA water, the LCRA General Manager will also be notified in writing within five (5) business days. The BRA's GM/CEO or his/her designee may decide not to order the implementation of a Drought Response Stage even though the trigger criteria for the stage are met. Factors which could influence such a decision include, but are not limited to; the time of year, weather conditions, the anticipation of replenished water supplies, or the anticipation that additional facilities will become available to meet needs. The reason for this decision should be documented. Additional documentation is not required if a Drought Response Stage is in effect due to an alternate triggering criteria. Termination of a Drought Response Stage The BRA's GM/CEO or his/her designee may order the termination of a drought response stage when the conditions for termination are met or at his/her discretion. The following actions will be taken when a drought stage is terminated: • The public will be notified through local media and the BRA Web site. • Wholesale customers will be notified by telephone with a follow-up letter/fax or e-mail. • The Executive Director of the TCEQ will be notified within five (5) business days. The BRA's GM/CEO or his/her designee may decide not to order the termination of a drought response stage even though the conditions for termination of the stage are met. Factors which could influence such a decision include, but are not limited to; the time of year, weather conditions, or the anticipation of potential changed conditions that warrant the continuation of the drought stage. The reason for this decision should be documented. Additional documentation is not required if a Drought Response Stage remains in effect due to an alternate triggering criteria. 6. Drought Response Stages, Measures to be Implemented, and Goals for Use Reduction The BRA will notify the Executive Director of the TCEQ within five (5) business days when any Drought Stage is declared under this plan. In turn and in compliance with Title 30, Texas Administrative Code, Chapter 288, Subchapter B, Rule § 288.22(b) (included in Appendix A), the BRA's customers are required to notify the Executive Director of the TCEQ within five (5) business days of any mandatory actions that are subsequently implemented under their respective drought contingency plans. In order to demonstrate compliance with requested water use reductions, BRA may require documentation of specific actions taken to reduce water use from customers that have irregular water use patterns that restrict the ability to establish a baseline amount to which water use restrictions will be applied. Stage 1 — Drought Watch Condition The Stage 1 Drought Watch condition is intended to raise customer and public awareness of potential drought problems. For water supplied from the Brazos River System, there is a voluntary Brazos River Authority Drought Contingency Plan TEXT May 2024 Page 9 of 14 target reduction goal of five (5) percent of the use that would have occurred in the absence of drought contingency measures. For LCRA water, there is a target reduction goal of ten (10) percent, as indicated in LCRA's Plan. The BRA's GM/CEO or his/her designee may perform or request implementation of any of the actions listed below, as deemed necessary: Inform customers of the Drought Watch Condition and request them to inform their customers, if any. Notify customers of actions being taken and urge activation by customers of appropriate water conservation measures to achieve the target water use reduction goal. Meet with customers to discuss current drought and possible measures to be taken if the drought intensifies. Initiate Stage 1 or equivalent of customer drought contingency plans, if available. Intensify efforts on leak detection and repair. Reduce nonessential water use. Initiate voluntary landscape watering schedules. Verify the location, depth, and operational requirements of intake structures. Increase public education efforts on ways to reduce water use. Investigate alternative ways to supply needs that could be implemented if the drought intensifies. In cooperation with customers, initiate the preparation of a specific drought response plan tailored to conditions as they exist at the time. Implement appropriate provisions of the specific drought response plan. For LCRA firm water, any requirements specified in the LCRA Drought Contingency Plan and associated Rules. Contact the TCEQ, United States Geological Survey (USGS), and U.S. Army Corps of Engineers. Inform them of the situation and request appropriate actions from each, such as closer monitoring to protect releases, more frequent gage inspections to reflect actual flow conditions more accurately, or a greater effort to meet exact release requests. • Other actions, as deemed appropriate, for the given situation. Stage 2— Drought Warninq Condition For water supplied from the Brazos River System, the goal for water use reduction under a Stage 2, Drought Warning Condition, is a ten (10) percent reduction of the use that would have occurred in the absence of drought contingency measures. If circumstances warrant, the BRA's GM/CEO Brazos River Authority Drought Contingency Plan TEXT May 2024 Page 10 of 14 or his/her designee may modify this goal. For LCRA water, the target reduction goal is twenty (20) percent, as indicated in LCRA's Plan. The BRA's GM/CEO or his/her designee may perform or request implementation of any of the actions listed below, as deemed necessary: • Inform customers of the Drought Warning Condition and request that they inform their customers, if any. • Notify customers of actions being taken and urge activation by customers of appropriate water conservation measures to achieve the target water use reduction goal. • Meet with customers to discuss the current drought and possible measures to be taken. • Initiate Stage 2 or equivalent of customer drought contingency plans, if available. • Encourage the public to wait until the current drought has passed before establishing new landscaping. • Initiate mandatory landscape and outdoor water use restrictions needed to achieve the water use reduction goal. • Initiate engineering studies to evaluate alternative actions if conditions worsen. • Further accelerate public education efforts on ways to reduce water use. • In cooperation with BRA customers, develop or update the specific drought response plan tailored to conditions as they exist at the time. • Implement appropriate provisions of the specific drought response plan. • For LCRA firm water, any requirements specified in the LCRA Drought Contingency Plan and associated Rules. • For EWCRWS, initiate preparations for the implementation of pro-rata curtailment of water diversion and/or deliveries. • Implement other measures identified by the BRA and its customers. Stage 3— Drought Emergency Condition For water supplied from the Brazos River System, the goal for water use reduction under a Stage 3 Drought Emergency Condition is a total reduction of twenty (20) percent in the use that would have occurred in the absence of any drought contingency measures. If circumstances warrant, the BRA's GM/CEO or his/her designee may modify this goal. For LCRA water, the target reduction goal is twenty-five (25) percent, as indicated in LCRA's Plan. If the combined storage of Lakes Buchanan and Travis continues to drop below 600,000 acre-feet, the mandatory pro- rata curtailment percentage may be increased as determined by the LCRA Board of Directors. The BRA's GM/CEO or his/her designee may perform or request implementation of any of the actions listed below, as deemed necessary: Brazos River Authority Drought Contingency Plan TEXT May 2024 Page 11 of 14 • Continue actions commenced under Stages 1 and 2. Inform customers of the Drought Emergency Condition and request that they inform their customers, if any. Notify customers of actions being taken and urge activation by customers of appropriate water conservation measures to achieve the target water use reduction goal. Require BRA customers to cease diversion and use of water under Interruptible Water Availability Agreements. • Cease the sale of water by the BRA under Interruptible Water Availability Agreements. Limit or restrict the temporary assignment of water by BRA customers to third parties in accordance with the terms of the underlying contracts. In cooperation with BRA customers, develop or update the specific drought response plan tailored to conditions as they exist at the time. Implement appropriate provisions of the specific drought response plan. Meet with customers to discuss the current drought and measures to be taken. Initiate the drought emergency or equivalent stage in customer drought contingency plans as necessary to meet the target water use reduction goal. Initiate mandatory water use restrictions such as prohibiting hosing of paved areas, buildings or windows, prohibiting operation of ornamental fountains, prohibiting washing or rinsing of vehicle(s) by hose, and prohibiting water use in such a manner as to allow runoff or other waste. Limit landscape watering at each service address. Prohibit draining and filling of existing swimming pools and filing of new swimming pools (pools may add water to replace losses during normal use). Prohibit establishment of new landscaping. Prohibit all outdoor watering, including hand held hoses. Implement viable alternative water supply strategies (this may require prior approval from TCEQ). • Coordinate with customers regarding the pro-rata curtailment process in the event that drought conditions persist or intensify and a Pro-Rata Curtailment Condition is initiated. For LCRA firm water, any requirements specified in the LCRA Drought Contingency Plan and associated Rules. Brazos River Authority Drought Contingency Plan TEXT May 2024 Page 12 of 14 • For EWCRWS, initiate mandatory measures to reduce non-essential water use and initiate pro-rata curtailment measures, pursuant to Texas Water Code § 11.039. Stage 4— Pro-Rata Curtailment Condition Under Stage 4 Pro-Rata Curtailment Condition the BRA's customers will be required to implement a mandatory pro-rata curtailment, pursuant to Texas Water Code § 11.039. All uses of water under Interruptible Water Availability Agreements in the affected part of the system will be suspended prior to and during any mandatory pro-rata curtailment of water use under long-term contracts. For LCRA Water, LCRA will curtail and distribute the available supply of firm water among its firm water customers and firm environmental flow commitments on a pro rata basis according to the amount of firm water to which they are legally entitled consistent with the Pro-Rata Plan for Firm Water Demands approved by TCEQ. For additional information regarding LCRA firm water see Appendix H. If conditions change while Pro-Rata curtailment is in effect, meetings with affected customers may be necessary in order to adjust the curtailment percentage. In the event that the BRA implements Pro-Rata curtailment under Stage 4 of this Plan, the GM/CEO will establish conditions under which the curtailment will be rescinded. 7. Required Provision on Distribution of Water in Case of Shortage in BRA Contracts The BRA water contracts shall include a provision that allows water curtailment in accordance with the provisions of Texas Water Code § 11.039 during water shortages. 8. Procedures for Granting Variances The BRA's GM/CEO or his/her designee may grant a temporary variance to the pro-rata water allocation policies provided by this Plan if it is determined that failure to grant such variance would cause an emergency condition adversely affecting the public health, welfare, or safety and if one or more of the following conditions are met: • Compliance with this Plan cannot be technically accomplished during the duration of the water supply shortage or other condition for which the Plan is in effect; or • Alternative methods can be implemented which will achieve the same level of reduction in water use. Variances shall be granted or denied at the discretion of the BRA's GM/CEO or his/her designee. All petitions for variances should be in writing and should include the following information: • Name and address of the petitioner(s). • Purpose of water use. Brazos River Authority Drought Contingency Plan TEXT May 2024 Page 13 of 14 • Specific provisions from which relief is requested. Detailed statement of the adverse effect of the provision from which relief is requested. Description of the relief requested. Period of time for which the variance is sought. Alternative measures that will be taken to reduce water use. • Other pertinent information. For LCRA water, LCRA may consider a temporary variance to the pro-rata water allocation requirement in accordance with LCRA's Plan. No variance shall be retroactive or otherwise justify any violation of this Plan occurring prior to the issuance of the variance. 9. Procedures for Implementation and Enforcement Appendix F is a copy of the BRA's Board resolution approving this Plan. Compliance with this Plan, as amended from time to time, is a condition in the BRA's water supply agreements. Failure to comply with the Plan is a violation of the water supply agreement provision and will be treated as such. For the EWCRWS, during any period when pro-rata allocation of available water supplies is in effect, wholesale customer(s) shall pay the Excess Water Fee for all water taken that exceeds the customer's pro-rata allocation. The Excess Water Fee is determined within customer's contract with BRA. 10. Review and Update The BRA shall review this Plan at least every five (5)years and shall update as appropriate based on new or updated information.

One of LCRA's primary responsibilities is to conserve and protect the soil and water resources of the Colorado River basin within LCRA's statutory district. The LCRA Board policy on Water Conservation directs LCRA staff and management to exercise leadership in promoting and, where appropriate, requiring the conservation of ground and surface waters within LCRA's water service area. The drought contingency rules are promulgated pursuant to LCRA policy and in compliance with the requirements of Texas Administrative Code,Title 30,Environmental Quality,Chapter 288, Subchapter B: Drought Contingency Plans. LCRA Board Approved March 26,2024 1 CHAPTER 1: PURPOSE AND AUTHORITY 1.1. Purpose The purpose of these rules is to extend existing surface and groundwater supplies through conservation and beneficial reuse and to help assure an adequate supply of clean water within the LCRA water service area. These rules apply to all LCRA water sale contracts except those expressly excluded below. These rules do not apply to water sale contracts for uses other than municipal use that have a Maximum Annual Quantity(MAQ)often (10)acre-feet per year or less and a term of three(3)years or less,to domestic use contracts often(10) acre- feet per year or less, or to landscape, irrigation and recreation contracts with a MAQ of up to 30 acre-feet per year to the extent those customers are covered by a drought contingency plan. 1.2. Authority These rules are promulgated in accordance with Chapters 11 and 152 of the Texas Water Code; Chapter 8503 of the Texas Special District Local Laws Code; Title 30, Chapter 288 of the Texas Administrative Code; LCRA Board Policy 501 —Water Resources; and the LCRA Water Management Plan. CHAPTER 2: DEFINITIONS Terms used in these Drought Contingency Plan Rules shall have the same meaning as the terms defined in LCRA's Water Contract Rules. Additional terms are defined as follows: 2.1. LCRA Water Management Plan A plan required in specific water rights held by LCRA and approved by the TCEQ that defines LCRA's reservoir operations, water management program, and policies under those water rights. 2.2. Municipal Per Capita Water Use The sum total of water diverted into a water supply system for residential, commercial,public and institutional uses divided by actual population served. 2.3. Municipal Use in Gallons Per Capita Per Day The total average daily amount of water diverted or pumped for treatment for potable use by a public water supply system. The calculation is made by dividing the water diverted or pumped for treatment for potable use by population served. Direct reuse volumes shall be credited against total diversion volumes for the purpose of calculating gallons per capita per day for targets and goals. 2.4. Ornamental Landscaping Irrigated turfgrass and other landscaping that is not regularly used for active and programmed recreational purposes such as sports fields, golf course areas used directly for sport(greens, tees, fairways, and practice areas), areas used for food production, maintaining cemeteries, maintaining the integrity of foundations, and preserving trees. 2.5. Ornamental Turf Grass Irrigated turf grass that is not regularly used for active and LCRA Board Approved March 26,2024 2 programmed recreational purposes such as sports fields, golf course areas used directly for sport (greens, tees, fairways, and practice areas), cemetery maintenance, and foundation maintenance. 2.6. Regional Water Planning Group Group created and supported by the Texas Water Development Board consisting of regional and local leaders of different backgrounds and various social, environmental and economic interests responsible for developing and adopting a regional water plan for its planning area. 2.7. Retail Public Water Supplier An individual or entity that supplies water to the public for human consumption. 2.8. Wholesale Public Water Supplier An individual or entity that for compensation supplies water to another for resale to the public for human consumption. The term does not include an individual or entity that supplies water to itself or its employees or tenants as an incident of that employee service or tenancy when that water is not resold to or used by others, or an individual or entity that conveys water to another individual or entity,but does not own the right to the water which is conveyed, whether or not for a delivery fee. CHAPTER 3: MUNICIPAL WATER USE BY RETAIL PUBLIC WATER SUPPLIERS 3.1. Minimum Requirements All LCRA customers with water sale contracts for this type of use shall develop, adopt and update in accordance with these rules a drought contingency plan that shall include at least the following minimum requirements: 1) Public Involvement Provision shall be made to actively inform the public and affirmatively provide opportunity for public input into the preparation of the retail public water supplier's drought contingency plan. Such acts may include,but are not limited to, having a public meeting at a time and location convenient to the public and providing written notice to the public concerning the proposed drought contingency plan and meeting. 2) Public Education Provision shall be made for a program of continuing public education and information. This information should include basic information about water conservation, effective conservation strategies, as well as information relating to drought, drought restrictions and other related issues. 3) Regional Planning Group. The plan must document coordination with the regional planning groups for the service area of the customer to ensure consistency with the appropriate approved regional water plans. 4) Specific Criteria. The drought contingency plan must include a description of the information to be monitored by the water supplier and the specific criteria, including supply-side and demand-side criteria, for the initiation and termination of drought response stages,accompanied by an explanation of the rationale for such triggering criteria. 5) Stages. The drought contingency plan must include a minimum of four drought or LCRA Board Approved March 26,2024 3 emergency response stages,providing for the implementation of measures in response to at least the following situations: 1) Drought response stages corresponding to LCRA's Drought Contingency Plan for Firm Water Customers. 2) Reduction in available water supply from LORA after a declaration of a Drought Worse than Drought of Record by the LCRA Board of Directors or other shortage resulting from emergency; 3) Water production or distribution system limitations; 4) Supply source contamination; and 5) System outage due to the failure or damage of major water system components (e.g., pumps). 6) Specific Goals. The drought contingency plan must include specific, quantified targets for water use reductions to be achieved during periods of water shortage and drought. Until mandatory curtailment is implemented by LCRA, implementation of measures to achieve these targets will be encouraged so as to further extend the supply available during drought. The customer shall establish the targets,which must be consistent with those in the LORA Drought Contingency Plan for Firm Water Customers (DCP). 7) Water Supply or Water Demand Management Measures. The drought contingency plan must include specific water supply or water demand management measures to be implemented during each stage of the drought contingency plan including, but not limited to, the following: a) Curtailment of non-essential water uses. Non-essential uses can include ornamental landscape irrigation, filling of pools and fountains, or any other water uses determined by the customer to be non-essential. In accordance with Stage 4 of the LCRA DCP, prohibition on irrigation of ornamental turfgrass and prohibition on the use of automatic sprinkler irrigation systems and hose-end sprinklers must be included as measures to curtail non-essential water use. b) Landscape watering schedules. The drought contingency plan must have a landscape watering schedule that restricts daytime outdoor water use and does not allow the irrigation of ornamental landscaping to occur more than twice a week on a permanent year-round basis. The plan must include a no more than once-per-week watering schedule for ornamental landscaping that is implemented at or before the initiation of Stage 2 of the LCRA DCP, a watering schedule limited to no more than 6 hours per week that is implemented at or before the initiation of Stage 3 of the LCRA DCP and eliminating operation of ornamental fountains in Stage 3. In Stage 4, the plan may allow irrigation of areas not defined as ornamental landscaping only with hand-held hoses with a working on/off nozzle,bucket, drip irrigation or soaker hoses for no more than 6 hours one day per week. c) Use of alternative water sources and/or alternative delivery mechanisms with the prior approval of TCEQ or other appropriate governing body with jurisdiction (e.g., interconnection with another water system, temporary use of a non- municipal water supply, use of reclaimed water for non-potable water, etc.). d) Additional measures. In preparing the plan, customer shall consider inclusion of LCRA- recommended measures for various stages, including those included in relevant template DCPs. LCRA Board Approved March 26,2024 4 8) Notification Procedures.The drought contingency plan must include procedures to be followed for the initiation or termination of each drought response stage, including procedures for notification of the public. 9) Variances. The drought contingency plan must include procedures for granting variances tot e plan. 10) Compliance with LCRA Drought Contingency Plan for Firm Water Customers.The customer's drought contingency plan will be used when the customer is asked to comply with LCRA's DCP. A statement shall be included in customers' plan that states they will comply with the LCRA DCP. 3.2. Recommended Minimum Drought Contingency Measures Under Pro Rata Curtailment. Recommended minimum drought contingency measures to implement under pro rata curtailment are found in Attachment A of these Rules. 3.3. Notification to LCRA and TCEQ. The customer shall notify the LCRA General Manager and the TCEQ Executive Director in writing within five (5) business days of the implementation of any mandatory provisions of its drought contingency plan. 3.4. Wholesale Customer Requirement. Customers shall include a provision in their drought contingency plans that every wholesale water supply contract entered into, extended or renewed after official adoption of the customer's drought contingency plan shall require each successive wholesale customer to develop and implement a drought contingency plan using the applicable elements in these Rules. If the customer's wholesale customer intends to resell the water, the contract between the initial supplier and wholesale customer must provide that the contract for the resale of the water must have drought contingency plan requirements so that each successive customer in the resale of the water will be required to implement measures in accordance with these Rules. Any retail public water supplier that receives all or a portion of its water supply from a customer shall consult with the customer and shall include in its drought contingency plan appropriate provisions for responding to reductions in that water supply. In the event the customer provides water to a retail public water supplier, if the retail public water supplier obtained less than 25 percent of its water supply in the prior calendar year from the Colorado River basin, demand measures in Section 3.1(g) that would restrict outdoor watering in Stages 2 and 3 are recommended, rather than required in the retail public water supplier's drought contingency plan. 3.5. Implementation and Enforcement. The drought contingency plan must include procedures for the enforcement of any mandatory water use restrictions, including specification of enforcement mechanisms (e.g., fines, water rate surcharges, discontinuation of service) for violations of such restrictions. A means of implementation and enforcement shall be evidenced by: 1) A copy of the ordinance, resolution or tariff, indicating official adoption of the drought contingency plan by the customer; and, 2) An employee or entity must be designated to oversee implementation of this plan. LCRA Board Approved March 26,2024 5 In a shortage of water not covered by the LCRA Water Management Plan or other conservation plan approved by TCEQ applicable to LCRA's firm water supply, a water sale contract customer who fails to implement its applicable drought contingency plan is subject to curtailment of firm water supply by LCRA based on the customer's pro rata share less the amount of water the customer would have saved if the customer had operated its water system in compliance with the drought contingency plan. 3.6. Other Approved Drought Contingency Plans.A drought contingency plan prepared and approved in the last five (5)years by LCRA or TCEQ and substantially meeting the requirements of these rules may be substituted for development of a plan to meet the LCRA rules. A determination that other approved drought contingency plans substantially meet the requirements of these rules shall be at the sole discretion of LCRA. If a water customer fails to develop, adopt, or update its drought contingency plan, then the customer shall adopt and implement any template drought contingency plan for this type of water use that may be developed by LCRA. CHAPTER 4: MUNICIPAL USE BY WHOLESALE PUBLIC WATER SUPPLIERS 4.1. Minimum Requirements.All LCRA customers with water sale contracts for this type of use shall develop, adopt and update in accordance with these rules a drought contingency plan that shall include at least the following minimum requirements: 1) Public Involvement. Provision shall be made to actively inform the public and affirmatively provide opportunity for public input into the preparation of the drought contingency plan and for informing wholesale customers about the plan. Such acts may include,but are not limited to, having a public meeting at a time and location convenient to the public and providing written notice to the public concerning the proposed drought contingency plan and meeting. 2) Public Education. Provision shall be made for a program of continuing public education and information. This information should include basic information about water conservation, as well as information relating to drought, drought restrictions and other related issues. 3) Regional Planning Group.The plan must document coordination with the regional planning groups for the service area of the customer to ensure consistency with the appropriate approved regional water plans. 4) Specific Criteria. The plan must include a description of the information to be monitored by the wholesale public water supplier,and the specific criteria for the initiation and termination of drought response stages, accompanied by an explanation of the rationale for such triggering criteria. 5) Stages. The plan must include a minimum of four drought or emergency response stages, providing for the implementation of measures in response to at least the following situations: drought response stages corresponding to LCRA DCP,reduction in available water supply from LCRA after declaration of a Drought Worse than Drought of Record by the LCRA Board or other shortage resulting from emergency. 6) Specific Goals. The plan must include specific, quantified targets for water use LCRA Board Approved March 26,2024 6 reductions to be achieved during periods of water shortage and drought.
