All existing park elements, including 2 metal playscapes w/ wood borders, wood pavilion, concrete basketball court, and sand playground surfacing, are approximately 25 years old and will be demolished and hauled off. The existing asphalt tennis court, multi-purpose playfield, and 1/10 mile concrete sidewalk will remain. Additional improvements in the project will include picnic tables, benches, relocation of a drinking fountain, trash receptacles, and park sign. The park is bisected by the boundary between the Edwards Aquifer Recharge Zone and the Transition Zone. Most of the development proposed in this plan occurs near this boundary or in the Transition Zone with the final discharge point of all stormwater occurring in the Transition Zone. In more detail, the project will involve removing approximately 1,395 sf of impervious cover consisting of existing concrete slabs and railroad tie borders, and installing approximately 9,458 sf of new impervious cover consisting of concrete sidewalks, slabs, and curbs. The current pervious area on-site is approximately 106,947 sf which will be only slightly reduced to 98,774 sf, or a change of 8,173 sf or 6.92%. The planned maximum depth of disturbance for the construction is to be less than two (2') feet. In general, finished grading of the site will be very similar to what exists today, and therefore drainage will remain as it exists today. Currently, approximately 98% of the site sheet flows southeast across a vegetated area into a grass lined drainage swale at the southern end of the site. The other 2% of the site drains east to a concrete drainage channel. The grass lined drainage swale drains into the concrete drainage ditch at the far southeast corner of the property. The design proposes to keep the same drainage pattern and to utilize the existing vegetative buffer strips. Due to the facts that the project will create a small net increase in impervious cover, that the depth of the construction excavation will be minimal, and that the majority of the storm water that falls on the completed project will sheet flow across vegetated surfaces, an exception from the requirements of filing a Water Pollution Abatement Plan (WPAP), performing a Geologic Assessment, and providing permanent water quality controls for the project is being requested. TCEQ-0587 Permanent Stormwater Section for Regulated Activities on the Edwards Aquifer Recharge Zone and Relating to 30 TAC §213.5(b)(4)(C), (D)(li), (E), and (5), Effective June 1, 1999 REGULATED ENTITY NAME: Stella Park Improvement Protect Permanent best management practices (BMPs) and measures that will be used during and after construction is completed. 1. X Permanent BMPs and measures must be implemented to control the discharge of pollution from regulated activities after the completion of construction. X These practices and measures have been designed, and will be constructed, operated, and maintained to insure that 80% of the incremental increase in the annual mass loading of total suspended solids (TSS) from the site caused by the regulated activity is removed. These quantities have been calculated in accordance with technical guidance prepared or accepted by the executive director. X The TCEQ Technical Guidance Manual (TGM) was used to design permanent BMPs and measures for this site. A technical guidance other than the TCEQ TGM was used to design permanent BMPs and measures for this site. The complete citation for the technical guidance that was used is provided below: 3. X Owners must insure that permanent BMPs and measures are constructed and function as designed. A Texas Licensed Professional Engineer must certify in writing that the permanent BMPs or measures were constructed as designed. The certification letter must be submitted to the appropriate regional office within 30 days of site completion. 4. NIA Where a site is used for low density single-family residential development and has 20 % or less impervious cover, other permanent BMPs are not required. This exemption from permanent BMPs must be recorded in the county deed records, with a notice that if the percent impervious cover increases above 20% or land use changes, the exemption for the whole site as described in the property boundaries required by 30 TAC §213.4(g) (relating to Application Processing and Approval), may no longer apply and the property owner must notify the appropriate regional office of these changes. This site will be used for low density single-family residential development and has 20% or less impervious cover. This site will be used for low density single-family residential development but has more than 20% impervious cover. This site will not be used for low density single-family residential development. 5. N/A The executive director may waive the requirement for other permanent BMPs for multi- family residential developments, schools, or small business sites where 20% or less impervious cover is used at the site. This exemption from permanent BMPs must be recorded in the county deed records, with a notice that if the percent impervious cover increases above 20% or land use changes, the exemption for the whole site as described in the property boundaries required by 30 TAC §213.4(g) (relating to Application Processing and Approval), may no longer apply and the property owner must notify the appropriate regional office of these changes. TCEC-0600 (Rev. 10/01/04) N/A ATTACHMENT A - 20%, or Less Impervious Cover Waiver. This site will be used for multi -family residential developments, schools, or small business sites and has 20% or less impervious cover. A request to waive the requirements for other permanent BMPs and measures is found at the end of this form. This site will be used for multi -family residential developments, schools, or small business sites but has more than 20% impervious cover. This site will not be used for multi -family residential developments, schools, or small business sites. ATTACHMENT B - BMPs for Upgradient Stormwater A description of the BMPs and measures that will be used to prevent pollution of surface water, groundwater, or stormwater that originates upgradient from the site and flows across the site is identified as ATTACHMENT B at the end of this form. X If no surface water, groundwater or stormwater originates upgradient from the site and flows across the site, an explanation is provided as ATTACHMENT B at the end of this form. If permanent BMPs or measures are not required to prevent pollution of surface water, groundwater, or stormwater that originates upgradient from the site and flows across the site, an explanation is provided as ATTACHMENT B at the end of this form. ATTACHMENT C - BMPs for On-site Stormwater X A description of the BMPs and measures that will be used to prevent pollution of surface water or groundwater that originates on-site or flows off the site, including pollution caused by contaminated stormwater runoff from the site is identified as ATTACHMENT C at the end of this form. If permanent BMPs or measures are not required to prevent pollution of surface water or groundwater that originates on-site or flows off the site, including pollution caused by contaminated stormwater runoff, an explanation is provided as ATTACHMENT C at the end of this form. 8. NIA ATTACHMENT D - BMPs for Surface Streams. A description of the BMPs and measures that prevent pollutants from entering surface streams, sensitive features, or the aquifer is provided at the end of this form. Each feature identified in the Geologic Assessment as "sensitive" has been addressed. 9. N/A The applicant understands that to the extent practicable, BMPs and measures must maintain flow to naturally occurring sensitive features identified in either the geologic assessment, executive director review, or during excavation, blasting, or construction. The permanent sealing of or diversion of flow from a naturally -occurring "sensitive" or "possibly sensitive" feature that accepts recharge to the Edwards Aquifer as a permanent pollution abatement measure has not been proposed for any naturally -occurring "sensitive" or "possibly sensitive" features on this site. ATTACHMENT E - Request to Seal Features. A request to seal a naturally - occurring "sensitive" or "possibly sensitive" feature, that includes a justification as to why no reasonable and practicable alternative exists, is found at the end of this form. A request and justification has been provided for each feature. 10. NIA ATTACHMENT F - Construction Plans. Construction plans and design calculations for the proposed permanent BMPs and measures have been prepared by or under the direct supervision of a Texas Licensed Professional Engineer. All construction plans and design information have been signed, sealed, and dated by the Texas Licensed Professional Engineer. Construction plans for the proposed permanent BMPs and measures are provided at the end of this form. Design Calculations, TCEQ TCEQ-0600 (Rev. 10/01/0/) Construction Notes, all man-made or naturally occurring geologic features, all proposed structural measures, and appropriate details must be shown on the construction plans. 11. X ATTACHMENT G - Inspection, Maintenance, Repair and Retrofit Plan. A plan for the inspection, maintenance, repair, and, if necessary, retrofit of the permanent BMPs and measures is provided at the end of this form. The plan has been prepared and certified by the engineer designing the permanent BMPs and measures. The plan has been signed by the owner or responsible party. The plan includes procedures for documenting inspections, maintenance, repairs, and, if necessary, retrofits as well as a discussion of record keeping procedures. 12. X The TCEQ Technical Guidance Manual (TGM) was used to design permanent BMPs and measures for this site. Pilot -scale field testing (including water quality monitoring) may be required for BMPs that are not contained in technical guidance recognized by or prepared by the executive director. ATTACHMENT H - Pilot -Scale Field Testing Plan. A plan for pilot -scale field testing is provided at the end of this form. 13. NIA ATTACHMENT I -Measures for Minimizing Surface Stream Contamination. A description of the measures that will be used to avoid or minimize surface stream contamination and changes in the way in which water enters a stream as a result of the construction and development is provided at the end of this form. The measures address increased stream flashing, the creation of stronger flows and in -stream velocities, and other in -stream effects caused by the regulated activity which increase erosion that results in water quality degradation. Responsibility for maintenance of permanent BMPs and measures after construction is complete. 14. X The applicant is responsible for maintaining the permanent BMPs after construction until such time as the maintenance obligation is either assumed in writing by another entity having ownership or control of the property (such as without limitation, an owner's association, a new property owner or lessee, a district, or municipality) or the ownership of the property is transferred to the entity. Such entity shall then be responsible for maintenance until another entity assumes such obligations in writing or ownership is transferred. 15. N/A A copy of the transfer of responsibility must be filed with the executive director at the appropriate regional office within 30 days of the transfer if the site is for use as a multiple single-family residential development, a multi -family residential development, or a non-residential development such as commercial, industrial, institutional, schools, and other sites where regulated activities occur. To the best of my knowledge, the responses to this form accurately reflect all information requested concerning the proposed regulated activities and methods to protect the Edwards Aquifer. This PERMANENT STORMWATER SECTION is hereby submitted for TCEQ review and executive director approval. The application was prepared by: Aileen Dryden Print Name of Customer/Agent q"�v'� �� Signa ur o tomer/Agent Date TCEQ-0600 (Rev. 10/01/04) ATTACHMENT B - BMPs for Uaeradient Starmwater Limited surface water, groundwater, or stormwater originates upgradient from the site and Flows across the site. To the northwest, there is an existing roadway with concrete curb and gutter. The roadway catches all upgradient stormwater prior to it entering the site and diverts it around the project site. To the south of the site, residential properties will contribute a small amount of stormwater that will flow across the site. A silt fence will be installed at the southern -most edge of the property line to filter any surface water or stormwater that originates on the residential properties before it reaches the project site. Once on the site, the stormwater will flow through the vegetated Swale allowing any impurities to be filtered out before reaching the point of discharge at the drainage channel. TCEQ-0600 ATTACHMENT C - BMPs for On-site Stormwater Permanent soil stabilization practices will be used in all disturbed areas, including the use of sod and/or hydro -seed to establish permanent vegetation. Water falling directly on or flowing across the site will travel over mostly vegetated area, and through the vegetated swales to purify the water before leaving the site. The majority of the stormwater flowing across the site will flow across a vegetated (natural) filter strip at least 50' in length before flowing across a small section of impervious surface. It will then continue on to the vegetated swale that is approximately 425' in length before reaching the culvert headwall. Once the stormwater enters the culvert, it will discharge into an existing drainage channel which runs another +/- 1,700' before entering the City's storm drain system and ultimately Brushy Creek. The site is a gently sloping site (generally less than 2%), located above the 2 - year storm elevation of the adjacent drainage, and will be maintained as a City - owned neighborhood park. It is our opinion that the site meets the criteria for natural vegetated filter strip, as identified in the Technical Guidance on Best Management Practices, and will provide sufficient load removal to handle the minimal new impervious cover created by the project.

Seasonal Mowing: The vegetative filter strip (turf area) will be mowed if it exceeds 18 inches in height using a mulching mower or if using a non - mulching mower the grass clippings will be removed from the vegetative filter strip area. All accumulation of trash and debris will be removed prior to mowing. Debris and Litter: Trash and litter accumulated in the vegetative filter strip will be kept clean on a regular basis. Sediment: Excess sediment that may build along the edge of the sidewalk or trail and the vegetative filter area will be removed to allow positive drainage and uniform overland flow. Excess sediment will be removed by hand or with a flat bottomed shovel. Lawn Care: A healthy dense stand of Bermuda grass will be maintained on the vegetative filter strip. Regular turf maintenance and mowing will occur on a 14-21 day cycle. Repairs/Retrofit: If any eroded areas should develop, they will be filled, compacted and re -seeded so that the final grade is level. Grass damaged during the sediment removal process will be re -seeded to establish vegetative cover. Bare spots that are identified will be restored by re -seeding those areas.

This TEMPORARY STORMWATER SECTION is hereby submitted for TCEQ review and executive director approval. The application was prepared by: Aileen Dryden Print Name of Customer/Agent Z 1�Prz,1.l_-a4n� S - ignatutg of Customer/Agent Date TCEQ-0602 (Rev. 10/01104) ATTACHMENT A — SPILL RESPONSE ACTIONS Material storage areas should be maintained to keep on-site material limited to only that needed for the job at hand. Liquid containers will be kept closed when fluids are not being used and drip pans will be under any containers with valves or spigots attached. All spills of any size will be immediately contained and all contaminated material placed into a proper container designed for transporting the hazardous materials. Containers will be sent to an approved hazardous materials site for proper disposal. There is a City fire station less than two (2) miles from the site with hazmat trained personnel on duty. The TCEQ will be contacted immediately as to the type and nature of all significant hazardous materials spills. The TCEQ will be notified as to the destination and travel days of any contaminated material. Contact information for spill response (see Section 1.4.16 Spill Prevention and Control for proper communication of spills): Round Rock Hazardous Materials Team: 512-218-5590 Williamson County Hazardous Materials Team: 512-943-1389 TCEQ Environmental Release Hotline: 1-800-832-8224 National Response Center: 1-800-424-8802 Contractor shall be required to comply with all spill prevention and control requirements of the Edwards Aquifer Rules: Technical Guidance on Best Management Practices (Section 1.4.16). 1.4.16 Spill Prevention and Control The objective of this section is to describe measures to prevent or reduce the discharge of pollutants to drainage systems or watercourses from leaks and spills by reducing the chance for spills, stopping the source of spills, containing and cleaning up spills, properly disposing of spill materials, and training employees. The following steps will help reduce the stormwater impacts of leaks and spills: Education (1) Be aware that different materials pollute in different amounts. Make sure that each employee knows what a "significant spill' is for each material they use, and what is the appropriate response for "significant' and "insignificant' spills. Employees should also be aware of when spill must be reported to the TCEQ. Information available in 30 TAC 327.4 and 40 CFR 302.4. (2) Educate employees and subcontractors on potential dangers to humans and the environment from spills and leaks. (3) Hold regular meetings to discuss and reinforce appropriate disposal procedures (incorporate into regular safety meetings). TCEQ-0602 (4) Establish a continuing education program to indoctrinate new employees. (5) Have contractor's superintendent or representative oversee and enforce proper spill prevention and control measures. General Measures (1) To the extent that the work can be accomplished safely, spills of oil, petroleum products, substances listed under 40 CFR parts 110,117, and 302, and sanitary and septic wastes should be contained and cleaned up immediately. (2) Store hazardous materials and wastes in covered containers and protect from vandalism. (3) Place a stockpile of spill cleanup materials where it will be readily accessible. (4) Train employees in spill prevention and cleanup. (5) Designate responsible individuals to oversee and enforce control measures. (6) Spills should be covered and protected from stormwater runon during rainfall to the extent that it doesn't compromise clean up activities. (7) Do not bury or wash spills with water. (8) Store and dispose of used clean up materials, contaminated materials, and recovered spill material that is no longer suitable for the intended purpose in conformance with the provisions in applicable BMPs. (9) Do not allow water used for cleaning and decontamination to enter storm drains or watercourses. Collect and dispose of contaminated water in accordance with applicable regulations. (10) Contain water overflow or minor water spillage and do not allow it to discharge into drainage facilities or watercourses. (11) Place Material Safety Data Sheets (MSDS), as well as proper storage, cleanup, and spill reporting instructions for hazardous materials stored or used on the project site in an open, conspicuous, and accessible location. (12) Keep waste storage areas clean, well organized, and equipped with ample cleanup supplies as appropriate for the materials being stored. Perimeter controls, containment structures, covers, and liners should be repaired or replaced as needed to maintain proper function. Cleanup (1) Clean up leaks and spills immediately. (2) Use a rag for small spills on paved surfaces, a damp mop for general cleanup, and absorbent material for larger spills. If the spilled material is hazardous, then the used cleanup materials are also hazardous and must be disposed of as hazardous waste. TCEQ-0602 (3) Never hose down or bury dry material spills. Clean up as much of the material as possible and dispose of properly. See the waste management BMPs in this section for specific information. Minor Spills (1) Minor spills typically involve small quantities of oil, gasoline, paint, etc. which can be controlled by the first responder at the discovery of the spill. (2) Use absorbent materials on small spills rather than hosing down or burying the spill. (3) Absorbent materials should be promptly removed and disposed of properly. (4) Follow the practice below for a minor spill: (5) Contain the spread of the spill. (6) Recover spilled materials. (7) Clean the contaminated area and properly dispose of contaminated materials. Semi -Significant Spills Semi -significant spills still can be controlled by the first responder along with the aid of other personnel such as laborers and the foreman, etc. This response may require the cessation of all other activities. Spills should be cleaned up immediately: (1) Contain spread of the spill. (2) Notify the project foreman immediately. (3) If the spill occurs on paved or impermeable surfaces, clean up using "dry" methods (absorbent materials, cat litter and/or rags). Contain the spill by encircling with absorbent materials and do not let the spill spread widely. (4) If the spill occurs in dirt areas, immediately contain the spill by constructing an earthen dike. Dig up and properly dispose of contaminated soil. (5) If the spill occurs during rain, cover spill with tarps or other material to prevent contaminating runoff. Signiflcant/Hazardous Spills For significant or hazardous spills that are in reportable quantities: (1) Notify the TCEQ by telephone as soon as possible and within 24 hours at 512-339-2929 (Austin) or 210-490-3096 (San Antonio) between 8 AM and 5 PM. After hours, contact the Environmental Release Hotline at 1-800-832-8224. It is the contractor's responsibility to have all emergency phone numbers at the construction site. TCEQ-0602 (2) For spills of federal reportable quantities, in conformance with the requirements in 40 CFR parts 110,119, and 302, the contractor should notify the National Response Center at (800) 424-8802. (3) Notification should first be made by telephone and followed up with a written report. (4) The services of a spills contractor or a Haz-Mat team should be obtained immediately. Construction personnel should not attempt to clean up until the appropriate and qualified staffs have arrived at the job site. (5) Other agencies which may need to be consulted include, but are not limited to, the City Police Department, County Sheriff Office, Fire Departments, etc. More information on spill rules and appropriate responses is available on the TCEQ website at: hftp://www.tnrcc.state.tx.us/enforcement/ememency response html Vehicle and Equipment Maintenance (1) If maintenance must occur onsite, use a designated area and a secondary containment, located away from drainage courses, to prevent the runon of stormwater and the runoff of spills. (2) Regularly inspect onsite vehicles and equipment for leaks and repair immediately (3) Check incoming vehicles and equipment (including delivery trucks, and employee and subcontractor vehicles) for leaking oil and fluids. Do not allow leaking vehicles or equipment onsite. (4) Always use secondary containment, such as a drain pan or drop cloth, to catch spills or leaks when removing or changing fluids. (5) Place drip pans or absorbent materials under paving equipment when not in use. (6) Use absorbent materials on small spills rather than hosing down or burying the spill. Remove the absorbent materials promptly and dispose of properly. (7) Promptly transfer used fluids to the proper waste or recycling drums. Don't leave full drip pans or other open containers lying around. (8) Oil filters disposed of in trashcans or dumpsters can leak oil and pollute stormwater. Place the oil filter in a funnel over a waste oil -recycling drum to drain excess oil before disposal. Oil filters can also be recycled. Ask the oil supplier or recycler about recycling oil filters. (9) Store cracked batteries in a non- leaking secondary container. Do this with all cracked batteries even if you think all the acid has drained out. If you drop a battery, treat it as if it is cracked. Put it into the containment area until you are sure it is not leaking. Vehicle and Equipment Fueling TCEQ-0602 (1) If fueling must occur on site, use designated areas, located away from drainage courses, to prevent the runon of stormwater and the runoff of spills. (2) Discourage "topping off' of fuel tanks. (3) Always use secondary containment, such as a drain pan, when fueling to catch spills/ leaks.

This RECHARGE AND TRANSITION ZONE EXCEPTION REQUEST FORM application is hereby submitted for TCEQ review and executive director approval. The request was prepared by: Aileen Dryden Print Name of Customer/Agent z -.Y gignatu4 of Customer/Agent Date TCEQ-0628 (Rev. 10-01-10) ATTACHMENT A - NATURE OF EXCEPTION FOR RECHARGE AND TRANSITION ZONE EXCEPTION REQUEST FORM (TCEO-0628) We request an exception from filing a Water Pollution Abatement Plan (WPAP) providing permanent water quality controls due to a small increase in new impervious cover and an exception to the Geologic Assessment due to the small area and depth of proposed soil disturbance. The exception request will allow the City to redevelop approximately 2.62 acres of parkland with a new playscape, pavilion, half -court basketball court, and approximately 1/6 mile of 5' wide concrete trail with other park amenities, including benches and picnic tables. The total amount of planned impervious cover will be approximately 19,320 square feet, which is a change of 8,173 sf from the existing impervious cover. The approximate flow length across vegetated area from the new impervious cover to the discharge point is approximately 50+ feet. The project is small enough that the construction time will be short (3 months). It is our opinion that the large vegetated area will have sufficient load removal to handle the minimal new impervious cover created by this project. TCE"628 ATTACHMENT B— DOCUMENTATION OF EQUIVALENT WATER QUALITY PROTECTION Equivalent water quality protection for this construction will be achieved with the existence of the vegetated area to where the new impervious cover will be graded. The construction will produce a small net increase in impervious cover (8,173 sf). The vegetated area on the project site and downstream of the project site provide a vegetative buffer/filtration strip of approximately 50+ feet which will have sufficient load removal to handle the minimal, new impervious cover created by this project.
