TO TH CITIZENS OF SAN ANONIO:

Since Januai, 1994, the San Antonio City Counci along with the chais of the Plannng Commssion, Zoning Commssion and the San Antonio Water System Board of Trustees have been meeting as a

Commttee of the Whole to discuss water qualty in reference to land use activities over the Edwards Recharge Zone. Our discussion focused on the area withi the City's jurisdiction, which is less than 2% of the total recharge zone. Our review included functional responsibilities related to staf and other agencies as well as explorig practica recmmendations which would update their efforts since the 1987, The Edwards Aquifer: Perspecives for Local and Regional Action report and its resolution on non-degradation of the aquifer. These organitional steps coupled with increasingly stricter guidelies for pollution control and prevention best amplifY the need for continued study of potential contamination and ongoing actions to educate and implement activities for prevention.

The commttee found that its approach must be expanded to include a comprehensive watershed management approach that takes into account federal, state and local requirements. This new approach would allow for prudent, responsible land use activities that with proper enforcement and oversight can occur over the recharge zone, transition zone and drainage areas as well as creeks and streas which flow through Bexar County. This approach coupled with physical programs such as drainage and flood plain management wil ultimately protect water quality for the aquifer and the streams and watercourses that cross Bexar County.

Water quality protection of our creeks and streams, now a national mandate as the stormwater program afects us al wi dimsh the potential for pollution as raiwater and other sudace materials channel throughout the County over sensitive areas.

Therefore, protecon of the Edwards Aquifer is important to al of us. It begins with education about how the system works, an awareness of its unique characteristics and a respect for its greatness.

Sjpcerely, ø j~ l~jJt i~f/ ~Ol~ I 'Mayor

3 DESCRIPTION OF EDWARDS GEOLOGY PHYSICAL CHARCTERISTICS OF THE EDWARS AQUIR

There are' three basic components to the Edwards. Aquifer system:

(1) the Drainage Area of the Edwards Plateau

(2) the Recharge Zone along the Balcones Escarpment, and (3) the. Artesian/Reservoir Area (including Transition Zone) afthe edge of the Gulf Coastal Plain.

Precipitation fallng on the drainage area. is transported by streams to the Balcones Fault Zone, where it penetrates the ground and recharges the aquifer. Tle groundwater then

moves by gravity though the pore spaces in the. limestone fromareas where the water levels

are at higher elevations to areas where the water levels are at lower elevations (toward the

major springs). Water is withdrawn by wells or discharged at the springs. If there were no wells, in the long run the average spring discharges would exactly offset the average annual recharge.

The "aquifer" often refers to the combintion of the recharge zone. and the. artesian zone. These areas total about 3600 square miles. The aquifer spans 180 miles from Brackettile, in Kiney County on the west, to Kyle, in Hays County on the east, and ranges from 5 to 30 miles wide.

Drainage Area

. About 4,400 square miles in 13 counties: Edwards, Real, Bandera, Kerr, Gilespie, Kendall, Blanco, as well as parts of Kiney, Uvalde, Medin, Bexar,Comal and, i Hays Counties. i I I.i . The drainge basin in' ths . area funnel. stormwater run-off into streams that flow across the recharge area. Since most. aquifer recharge occurs .tho~gh streambeds, ths funneling effect is an importt function of the drainge' area. . The Edwards Plateau is composed of Edwards and Glen Rose limestones. Since the Edwards limestone is porous, some of the run-off in ths area is stored temporarily after a rawal. Stream that originte flOm the' drainage area continue to flow for long period .. a.fer raintorms. ,. becausetbe water,storedninJhe limestone slowly migrates out of the rock to sustain the base flow of the streams.

. The land surface on the Edwards Plateau ranges in altitude from 2300' msl in the west to about 100' msl in the east. Vegetation is priarily woodlands' (oak,

mesquite and cedar), with large areas cleared for livestock grazing.

5 PHYSICAL CHARCTERISTICS OF THE EDWARS AQUIR

Recharge Zone

. About 1Soo square miles directlysouth ' of the drainage ~rea, including parts of Kinney, Uvalde, Medina, Bexar, Comaland Hays Counties.

. In this area. many closely. spaced, nearly vertical faults occur along the relatively narrow BalconesFaultZone,exposing. fractured. Edwards .Lime.stone at the land surface. As the streams originating in the Drainage Area cross this zone, much of their, flow percolates though the streambeds into the aquifer. All major streamsín the region except the Guadalupe River lose water to the aquifer. Sinkoles and cavern are common in this area. i' i . During, low-flow periods, virtally all streamflow is reciiarged to the . aquifer. The \

streams in the western part of the plateau. . are thus generally dry when they reach the Gulf Coastal Plain, except during floods when streamflow exceeds the recharge rate.

. The, NuecesRiver Basin accounts for 58% of the aquifer's average total recharge.

The Bexar County portion of the recharge zone (some 175 square miles) accounts for only 10% of annual recharge. Only about 34.S square. miles (2.3 %) . of the recharge zone iswithnthe citylimits ofSah Antonio. Approximately 11.6% of the recharge zone is located in Bexar,. County.

Artesian/Reservoir Area

. The Aresian/Reservoir Area (including the tranition zone) consists of about 2100

square' miles,. directly . south of the rechage zone.. Ths. includes. parts of. Kiney,

Uvalde, Medina, Be~ar, Comal and Hays Counties, and. very small portions of AtascosaandGuadaIupe . Counties.

. In ths area, the Edwards Limestone is buried beneath Del Rio Clay and other confing formations..' . The .. Edwards Formation. averagesaboutSOO. feet. thick in this area, and itslopes down to about 100 feet below the Jandsurface at the southern

edge of th ZOiie.

. Ths area consists of many pore ...spacesand..a complex network.ofsQlutionopenigs,

with a great capacity for storig and moving .water. The groundwater in ths area moves generally east and then norteast, toward the spring openigs.

. The part of ths area with the greatest porespace and' the highest yielding wells is a relatively narrOW band from near San. Antonio. norteastward though the vicinty

of Comal and San Marcos Springs. Wells in ths band commonly yield 600-700 gallons per minute. . A single artesian well in southwest Bexar County, at the Living

Waters catfish farm, produces about 40 milion gallons per day.

6 PHYSICAL CHARCTERISTICS OF THE EDWARS AQUIR

. The . ,transition zone is generally that ..area where geologic formations including portions of the Del Rio Clay, Buda. Limestone, Eagle Ford GrouP,... Austin Chalk,

Pecan Gap Chalk, and Anacacho Limestone crop out in proximity to and soutli and southeast of the. recharge zone and . where. faults, fractures, and Qther geologic features present a possible avenue. for recharge of surface ,water .to the Edwards Aquifer. The transition zone is also idtmtified. as that area designated as such' on official maps. in the offices of the . Texas NaWralResourceConservation Commission

(TNRCC) .and. appropriate....underground water. conservation districts. The.transition zone ....is . primarily used in boundary definition for Petroleum Storage Tank' issues by TNRCC.

. . A groundwater divide in Kinney County separates ths region from another water bearing section of Edwards Limestone which extends though Del Rio (San Felipe

Springs) and into.Mexico. Another groundwater divide in Hays County separates the San Antonio section of the aquifer from the region which supplies Barton Sprigs~ in Austin.

. L The "Knppa Gap", an undergrouiid structure., in. the aquifer in western Medïn County, retards the flow of water from west to. east, but does not separate, the aquifer

into. isolated sections. ..' It causes., the water in the "Uvalde pool" of the aquifer .to i . remain at higher elevations than the .water in the "San Antonio ..pool." edge of tlie resetvoirarea is defmed.by a "bad waterline," which . The southernseparates . high quality waterfrombr:ickish to saline water(:: i,oomg/Lof dissolved solids) to the south.. and at lower elevations. The potential for movement of ths boundary isthesubjeèt of a. long-term study by the. U.S,. Geological . Survey, the Edwards Underground Water District and the San Antonio Water System..

. The quality of water in . the reservoir. surpasses all federal . dring water standards. Gas chlorintion is the only treatment which is required before water is introduced into the. San Antoiiodistrbution system.

. Conventionay ,the water level in the Edwards ismeasured at the "1-17 "well (A Y -68-

37-203) at Fort San Houston in San Antonio. The level in ths well is very closely

. correlate .. with-the rate of discharge at . Cornal.. Sprigs. Historical-data are- -as follows:

Record High (6/14/92): 703.2' msl Record LOw (8/17/56): 612.5' msl Long Term' Average: 663.8'msl

7 . PHYSICAL CHARCTERISTICS OF THE EDWARS AQUIR

Groundwater Flow

Water in the aquifer moves generally south from the recharge zone. to the artesian zone, and then east and norteast toward natural discharges at springs. The rate of movement is

extremely high in comparison with sand aquifers. Estimates at several sites range from 2 to 31 feet per day, 2 but local transmission rates of as . much as 1000 feet per day have also beenhydrology. recorded. 3 The variation in flow velocities reflects the ' aquifer's complex geology and Changes. in aquifer well levels, however, reflect changes in pressure within. the confined zone of the aquifer -- notthe actual movement of water underground. For this reasoh, recharge events raise well levels essentially instantaneously . across a wide . area. Correspondingly, pumpage at 'one site quickly affects well. levels' miles. away. i i, Spring Discharges

Before there was any pumping, the aquifer was held · in a natural balance between recharge and the spring discharges. There are five major sprigs in the region: Leona (in Uvalde), San Antonio and SaiiPedro'(in San Antonio), Comal. (New Braunfels), and San Marcos. Comal and San Marcos Springs are the largest in. Texas. A number. of other. sprigs. also flow intermittently i whenever current recharge raises the level of the aquifer to ,sufficient

elevations. If there were no pumping from the, aquifer, in the long run these spring

discharges would stil (after some time Jag) 'exactly offset the aquifer's recharge.

8 PHYSICAL CHARCTERISTICS OF THE EDW ARS AQUIR

Water in Storage

The total volume of water stored in the aquifer is estimated to be between 25 and 55 milion AF. 4

. This. is more than the total in all of the surface reservoirs in Texas combined.

. However, much of this water iswithin smaH openings in the rock matrix, not in larger openings where most groundwater is produced. Therefore the total. amount which could actually be. pumped is unkown.

. Within the range of historical experience, each! foot decline in the J-17 well is associated with about 40,000 AF of total pumping and spring discharge. 5 This. ratio between water level and water volume is approximately constant down to the recorded minium of 612' msl. Whether it would remain constant below that level is unkown. . Assuming this ratio does remain constant down to the level of San Marcos Springs (575' msl),there would be about 1.8 milionAFavailtlble between the point where Comal Springs go dry and the point where San Marcos Springs' would go dry.6

The Bad Water Line7

II The bad water line" is the boundar between high quality water and brackish to Saline water ()o.1 ,OOmg/L of dissolved solids), at lower levels in the Edwards limestone. This line extends along the southern edge' of the aquifer froin Brackettile to Austin.

. This nonpotable water has beeIl found to. both horizontally and vertically below the

freshwater aresian zone. If the fresh water aquifer level is lowered because of groundwater pumpage or decreased recharge, ths water could. migrate from the

deeper part of the aquifer.

ì . Increases in salinity of well water could result in public water supplies that would not i 1 meet the state Department. of Health water quality standards. Ground water in some wells along the bad water line 'did d~teriorate in the drought of the.. 1950s. Hôwever, good. quality water returned. quickly when the water levels rose again. after the i drought.

. Movement of the bad water line could also jeopardize the quality of the spring flows, i particularly at Comal Springs (which are . less than2 miles fromthis boundary) and

San Marcos Springs (1/2 mile from this line) . Deterioration in the quality of spring

water, .could result. in the loss of aquatic. biota within the. springs and the aquifer. j However, . there are no specific data to describe the impact which water quality

changes. . might . have '.. on . these organisms, and .no . watel' quality changes have'. been i ' observed to date at either location. . J

. Flow' from the bad, water zone to. the. freshwatetzoneise.videncedbya small

increase in sodium and chloride which has been observed at Barton.. Springs in Austin

as spring discharge declines... Although Barton Springs is isolated hydrologically from

the. San " Antonio region of the. aqiiifer, ths suggests . that . a.. similar' mechanism could work at Carnal and Saii.Marcos Springs.

District, and the . The U.S. Geological Survey, The EdwardsUnderground Water San

. Antonio Water System have un4erten ' a long. term study. of the potential for

moveinent . of the, bad water line and its possible effects. Ths study involves a network of monitoring wells in Bexar, Comal and Hays Counti.es. Recharge

. The Edwards. isiiniqueamong groundwater,. aquifers in its . ability to recharge large' quantities

of water quickly. On average, ths recharge is offset by discharges, both from natural springs and by pumping.

. Recharge.comes priary from surface streans flowing over the fractured Edwards

limestone which is exposed atthe surface of the land in the recharge zone. Asinall

amount also comes from the iniltration of rainwater falling directly over the

recharge zone.

. Two-thds of the rechage occurs in the western counties of the aquifer region, about

10% in Bex~.. CoUPty"and . mostoLthe,restu inCoinaIC_Otloty'uThe n Çitygf Sail,.

Antonio includes about 34.5 square miles (0.4%) of the area of the recharge zone.

Percentages of recharge by county and by river basin are in Tables 1 and 2.

the . Data on quality of recharge have been calculated, by U.S. Geological Survey since

1934. The long term average recharge (1934-1991) is approximately 651,7ooAF/YR.

. The average recharge, however, is subject to extreme varation from year to year.

of 43.700 Actual recharge has. ranged from a low acre-feet in 1956 (at the height of acre-feet in 1987. the drought in the 1950s) to over 21 milion

10 PHYSICAL CHARCTERISTICS OF THE EDWARS AQUIFER

. The variation increases the stress on the environment at Comal and San Marcos Springs. Comal Springs dried up completely from June to November, 1956, resulting in a loss of some species until they were reintroduced from San Marcos Springs in 1975.

. A verage annual rainfall in the region ranges from 21. 16 inches in Brackettvile to 33 . 8 inches in San Marcos. Historical data on rainfall in the region is contained in Table 3.

. A verage rainfall over the last two decades has been substantially above the long term average for the region. This has increased the spring discharges and held down the demand for pumping in recent years, thus obscuring a developing imbalance between recharge and total discharges.

. The historical balance between recharge and discharges (springs, pumping, and total) is in table 4.

System with the responsibilty to inspect and evaluate sanitary sewers withi the Edward's

Aquifer Recharge Zone on a 5-yearcontinuing basis. .' The affected area is divided into five

s,ubareas. Each year 20%. of the total area is completed.

The.. inspection and evahiation of the Sanitary .Sewer System begins with a visual inspection and docuiientation,of the manhole condition.,. After visual inspection is completed, a physical

inspection of the integrity of the Sewer lateral,. sewer mains andclean..outsbegin.. . A smoke test

20 WATER POLLUTION ABATEMENT PLANS

The Edwards Aquifer Rules (TAC 313.4) requires that an'application known às a Water Pollution Abatement Plan (wAP) be submitted for new development , on the Edwards Aquif~r Recharge Zone. While initially thes~ reports were usually little more than a few

pages in length, they have expanded into extensive tepons. The type of WPAP to be submitted wilLdepend on the nature 'of the proposed project. The City Council Coinittee in their. report THE EDWARS AOUIFER: PERSPECTIVES FOR LOCAL AND REGIONAL ACTION made recommendations " for increasing,..the role of both the. City ofSanAntonioándthe Edwards Underground W.ater

District in, reviewing new developmentoatheRecharge . Zone. Currently, .. four copies of each 'WPAP . must be submitted tOithe Texas Natural Resource Conservation Commission forr~view..The copiesar~ distributed to both the local Distrct.lJoffce.andtheState office of the Texas Natural Resource Conservation Commssion" the San ,Antonio Water

System, and'the Edwards Undergr()uiid Water Distrct. Both the San Antonio Water System and the Edwards Underground Water Distrct have 30 days to review the WPAP and make comments back to the Texas Natural Resource. Conservation Commission office regarding recommendations,., and concern. . The , Texas, Natural Resource, Conservation Commssion reviews the cOmments made'.by the twoJocal ,authorities." lfthey approve these cOmments, they . wil. be included in, the.

22 EDWARS AQUIR TECHNICAL GUIANCE MANAL

The Texas Natual Resource ,Conservation Commission has developed a Techncal Guidance

Manual to assist the regulated community incompliance with the Edwards Aquifer Regnlationsas detailed in 30 Texas Adminstrat;.ve Code (T AC) Chapter 313, also known -1 as the "Edwards Rules". , Th~ San Antoni() Water System participated ,inthe development I i of this Technical Guidance Manual, as well as, other city agencies and regulatory authorìties

(Le. City of Austin, Baron Springs, Edwards Underground ,Water District,etc.) which are located oii,orhave jurìsdictionoverregulated activities on the Edwards Aquifer Recharge Zone.

Ths Techncal Guidance Manualisexpected to aid the regulated community by providing

design criteria , for non point source 'filtration design and' by providing, recognied alterntives

(Best Mangement Practices) which can be utilized. A large part of the Techncal ,Guidance

Manual is based on requirements from the City of Austin and the Lower Colorado River

Authorìty, as well as, requirements set fort in the U.S. EPA National Pollutat Discharge System Elimination System (NPDES).

It is hoped that the Techncal Guidance Manual wil provide a mean to addresS some of

the problems which arise from lánd use activities on the Edwards Aquifer Recharge Zone and possibly aid in future "Edwards Rules" changes. If successful, ths document may be

adopted as par of the TAC Chapter 313 rules.

23 ZONING REPORTS

On October 2, 1975, City Council established the Edwards Recharge Zone Overlay District. Development with ths District is under tighter restrictions than the Chapter 313 Rules in order to prevent containation to the citizens of San Antonio water supply and to protect the public's health.

Under the rules of the Unified Development Code, if an applicant asks for a change of zonig within the Edwards Recharge Zone District, the San Antonio Water System is responsible for performing a site assessment and providing a report for first, the Zoning Commission's review and secondly the City Council's review. The report provides a site description, identification of potential recharge features, an assessment of their sensitivity, environmental concern associated with the land use, a recommendation whether to approve or disapprove the land use, and specific recommendations that an applicant should follow if the land use is approved. If City Council approves the land use and the recommendations, then the applicant must adhere to each one. Restrctions put into place by the City Council must be at least as strict as the Edwards Aquifer Rules.

DIREXOR OF ENIRONMENTAL MAGaNl 29 PLATS AN PUD PLANS

The San Antonio Water System, Aquifer Studies Division reviews plats to determine if they reflect the Site Specific Water Pollution Abatement Plan the engineer and/or the developer has approved and any special, zonig requirements.

Prior to March 1993, plats were reviewed by the San Antonio Water System. If the plat was found to be in accordance with the Unified Development Code, an approval letter with' a box to indicate approval or disapproval was checked-off. In March '1993, the Plannng

Commission requested the San Antomo Water System to provide a' written report detailng

staff's assessment of the geologic conditions. which exist at the site and to observe any

possible environmental concern. Until recently" the developer was required to have all Water' Pollution Abatement Plans approved before a plat could be approved. Planng staff determined that the wording, of the Unified ,Development Code requires only, a ,Sewer

Collection System Water Pollution AbatenientPlan be required before a plat could be

approved (Unified Development Code IV-51 Section 35-4210). Now, staff determines if the

Sewer Collection System Water Pollution Abatement Plan has been approved by the Texas Natural Resource., Conservation Commission and whether any special conditions were required which, might affect . a plat. A site specific Water Pollution Abatement. Plan which addresses stormwater run-off is frequently completed and approved by the Texas Natural

Resource COnservation' Commission prior to the platting process however, it is only required prior to release of the building permits.

Planed Unit Development (PUD) plans are currently reviewed to determe if any geologic features exist on the 'site. Any significant geologic featues found to exist on the site are deed recorded. prior to approval by the San AntJnio Water System.' Approval of the PUP plan does not include' a written report. Staff reviews the site with a detailed report at a later date when the site is platted. Staff verifies' the incorporation of any Zonig recommendations into 'thePUD plan prior to approval by the ,San Antonio Water System.

In accordance with section 313.5 (c)(9) of the TNRCC Edwards Aquifer Protection Rules, all private service laterals after installation of, prior to covering, and prior to connecting the private service lateral to an organied sewage collection system must be visually inspected along with the connection to the service system.

Responsibilty for inspecting construction of private sewer laterals on the Edwards Recharge Zone is divided by the boundaries of the city limits. Private service laterals located inside the city limits are constrcted according to provisions provided in the City of San Antonio's Plumbing and Building Codes. Inspection of the laterals are made by the Building Inspections Departent.

Private sewer laterals to be constructed outside the city limits but with the Recharge Zone of the Edwards Aquifer must comply with Aricle iv of the Subdivision regulations of the Unified Development Code. Inspection of these laterals into the extraterrtorial jurisdiction are made by the Stormwater Departent of the San Antonio Water .System. Both the City Plumbing Code and the Unified Development Code establish mium bedding requirements, pipe design specifications, backfll requirements, and conformance standards for connecting to an existing sewer main. Once the private service lateral is found to be constructed in conformity with all applicable regulations, a certificate of approval is issued.

1993 IV-73 46 S.B. 1477

Nearly all of S.B.1477addresses water supply and the management of the Edwards Aquifer. There is a brief section of the, bil. which addresse,s the" issues of Water quality.

Under S.B. 1477, section 1.08, the new Edwards Aquifer, Authority would have general powers to police the Edwards., Aquifer. As stated in the bil, the new Edwards Aquifer

Authority would have general powers COnsisting of, "allof the, powers, rightS, and privileges necessary ,to mange, conserve" preserve, and protect the aquifer and to increase the recharge of and 'prevent the waste or pollution of water, in, the aquifer."

The Texas Water Code provides for local governmentS ,to continue to maintain pollution control powers and allow for local control, of water qu~lity.

47 WORK PROGRAM

,/ OVERVIEW OF SAN ANTONIO WATER SYSTEM ENVIRONMNTAL RESPONSffILITIES

Upon merging the City Water Board, Wastewater. Departent,Stormwater activities, Water Resources . Program, and the Alamo Conservation and Reuse, District, many of the enyironmental duties which. were performed by the City, of San ,Antonio carried over to the new San Antonio Water System (SAWS).

SAWS main environmental responsibilities include:

1. Evaluating and monitoring development over t1e Recharge Zone of the Edwards Aquifer.

2. Establishment and continued monitoring of the EPA'smandated stormwater sarpling program..

3. Assess the water quality of San Antonio Water System public supply Wells.

4. Review enviroinental .issues, envirOnmental, regulatiofi, and environmental permit applications to determe their impact on, the ,City of San Antonio's water supply and wastewater program.

,5. Compliance with EPA regulations regarding treatment plant effluent, discharge.

6. Monitoring and testing of industrial discharge . into City of San Antonio sew~r lines.

7 ¡ Response to emergency situations and spils which affect San Antonio Water System utilties.

8. Assist in designating and protecting. environmentally sensitive areas.

The San Antonio Water System',is responsible for monìtorig, and evaluating, development

on the Recharge Zone in order to prevent the degradation of water quality with the Edwards Aquifer. Ths requires workig closely with State and Local agencies along with

developers and. ,engireers .. to see that thsobjeçtive is met The. ,process of monitoring development over, the Recharge Zone of the Edwards Aquifer, includes but is not limited

to the '" fOllQwfug:_

1. Reviewing 'Water Pollution Abatement Plans ,(WPAP).

2. Review of zonig and re-zonig requests.

3. Plat andPUD plan revieW for compliance with WPAPs.

4. Review of Sewer Collection System applications (SCS).

5. Review of Aboveground Storage Tanks/Underground Storage Tanks applications. 49 OVERVIEW ÙFSAN ANTONIO WATER SYSTEM ENVIRONMNTAL RESPONSffILITIES

6. Smoke Testing.

7. Sewer line inspection inside the city limits. and the, extraterritorial jurisdiction 1 (ETJ) . 8. Monitoring th-two (32) water sampling stations in the extraterritorial jurisdiction and within, the, city limits to study the effect of increasing

urbanation over the Edwards recharge zone.

9. Building Permits and Certificates of Occupancy.

The fInal assessment ,and recommendations are put into reports to aid City Council, the Zonig Commission, and the Planng Commission in the decision making process. Recommendations and comments are also made i to the Texas Natural Resource Conservation Commission.

Since the City Council Committee on the Edwards Aquifer met and review~dthe separate

röles ,of the regulatory agencies in 1987 and made their recommendations, there has been

. a. closer working relationship, between the Texas Natural Resource, Conservation

COmmission, the Edwards Underground Water District and SAWS in order to protect the

Edwards Aquifer. While not always in agreement, the. communication has improved

therefore improving .assessments made on land use and in evaluating potentially . significant recharge features. Because' of the increase in development activity" the Texas Natural

Resource, Conservation Conuissia.n has been limited by time in the area of enforcement.

SAWS,. working through Building Inspections with the City of San Antonio, has attempted

to. assist the' Texas Natural Resource Conservation Commission in the area of enforcement.

The City of San Antonio/San Antonio Water System has begun to implement a

comprehensive protection, program. with stringent measures to achieve the goal of preventing degradation, of,.the, groundwater quality. The comprehensive groundwater/watershed protection program must. include the following components:

a. Establisblg a coordinated work effort for groundwater quality protection and

watershed,- -- -- _.- management; and '

b. The assessment of the risks of pollution of the aquifer from all potential

sources and the takg of measures to reduce those risks; and

c. The prevention of pollution of the aquifer through those sensitive areas determined as the drainage area, recharge 'zone and transition zone; and

d. The monitoring of runoff waters to furter reduce the level of any pollutants over the Edwards ,Aquifer in Bexar. County.

50 OVERVIEW OF SAN ANTONIO WATER SYSTEM ENVIRONMNTAL RESPONSmILITIES

In addition, though an interlocal agreement, SAWS has also been working with the Edwards Underground Water District to monitor the effects of development over the recharge zone by setting up sampling stations and testing stormwater quality.

Participation by Bexar County has been limited in the regulation of the Edwards Aquifer. Their role is mainly in the area of regulating septic tanks.

51 ACTIVITIES TO DATE

ì - CURRNT ACTIVITIES:

In 1977, the City of San Antonio established the Edwards Recharge Overlay District, which established at a local level the first steps to place landuse restrictions though Zoning. Since that time, several amendments and changes to the program have been made.

Currently, ,any proposed regulated activity is subjected to an intense review process by the State, with review and comments by the Edwards Underground ,Water., District, and the San Antonio Water. System. In addition, if required,. the proposed land use is also reviewed as

a part of the zonig and platting. processes where even stricter requirements may be placed on the development by the San Antonio Water System.

Once the proposed developments have been approved and constrcted, both the San Antonio Water System and the City of San Antonio Building Inspections Departent wil

inspect construction to inure that the City Codes, the Unified Development Code, and any other requirements approved during the. review process are met.

While the review and inpection, processes' have been amended several times since 1977, ithe monitoring process has developed slowly. Monitoring, by the, Health Departent has

occurred over the past 20 years, however, the range of chemicals tested for has been limited. i. Studies by theU.S.G.S.havealso occurred ona regional basis. In 1988, the. City of San

I Antonio in cooperation with the Edwards Underground Water District,begaiiestablishig

sampling stations on the Recharge Zone whie the ,City placed other stations along creeks

and streams thoughout the rest of the County. The, sampling stations above the recharge

zone monitor stonnwater which is discharged into stream channels and flows over and

recharges the Edwards.Aquifer. Stations below the recharge zone monitor changing'

conditions as the creeks flow downstream. There are currently thirt-two (32) SamPling stations in place to monitor the stormwater quality. flowing across the Recharge Zone.

52 ACTIVITIES TO DATE

ONGOING INITIATIVES:

Before the merger of the different entities, which noW make up the San Antonio Water

System, the review process , for development on the Recharge Zone was fragmented having been performed by different divisions and departents. Since the merger, communication between the different., entities involved in water quality protection has allowed for a more effective review process and therefore a more effective enforcement policy.

Currently, the San Antonio Water System is workig to comply with.the National Pollutant

Discharge Elimination Srstem (NPDES) permit. The Environmental Protection ,Agency

(EPA) has passed regulations ,that require a permit to discharge stormwater, off-site. The dischargedstormwater wil have. to be tested and meet certin requirements under the Clean

Water Act. This means all stormwater run-off wil have to be treated on-site. To meet these new règulations, the. San Antonio Water System" has been workig on. pollution prevention, ordinances, which wil ' be .. enacted. in ,1994' .concurrent with, issuance of San

Antonio's permit by EPA.These' ordinances wil also aid in protecting stormwater quality

' which ,recharges the Edwards Aquifer as well as other sensitive, areas of the county. .

In addition,. ne\\ developments..proposed over the, Recharge Zone are reviewed. to .ensure compliance with current . federal, state, andlocalregulations. San Antonio Water System programs to furter enhance staff continually look for Ilewlyengineered ' technques and protection of the Recharge Zone. It is, the similar goal of abating potential containants from, development, providing for stricter ,development standards and enforcing these measures which has, helped. merge, the, different entities which.make up .the San Antonio

Water System and to not only look to protecting lhe Recharge Zone but to manage entire watersheds.

53 WORK PROGRA

The following work program of recommended po~icy statements ~nd implementation ,provide

the basis for actions to ,betaken by staff to proceed, with a comprehensive water quality program. These .33, recommendations cover regulatory' and techncal.measures to .protect

66 . Excerpt From The Mayor i s Press Conference November 22, i 993 The second anouncement is the convening of City Council into a Committee of the Whole to review aquifer protetion meaures.

. In 1987, I served as a member of Mayor Cisneros' five-member committee on aquifer protection. As a result, a number of major protecaon meaures were underten in the City of San Antonio in the form of local ordinances. Unfortunately, a great dea of misinformation exists concerning ongoing state and local as well as regional effort to monitor and protect the qual~i.y of the City's sole source of water. . - . J . ~ ' . It is time to review those provisions to determine if new actions by the City and the State are required to protect the overal quality of water recharging the Edwards Aquifer.

. Ths Committee of the Whole wil issue a report by May 1 and wil be stafed by . Rebecca Cedilo, Vice President of Planning for the San Antonio Water System. "Becky was our lead staf person on the 1987 committee and the continuity she provides wil make this a very effcient process. The Committee wil reyiew:

. Existing city, Edwards Underground Water Distrct and state laws, regulations .. or ordinancesand.establisbed. policies_addressing recharge quality. protecon

. The status of surface, stonnwater and aquifer water qualty monitoring activities

. The effect, when Senate BUl 1477 is finally cleaed, of this legislation on protection of aquifer water quaty

. Ongoing city initiatives related to water quaty protection

. The relationship between any other city functions, mandates or initiates related to water quality protection

. Any recommendations on area on which this committee should focus regarding water quality issues, revision to city ordinances, subdivision regulations, regional water authority rules or state legislation related to additional protection of aquifer water.

. The Council wil convene as Committee of the Whole in ealy Januar to receive an initial reprt from SAWS staff to begin the review/recommendation process. The Chaien of the Planning and Zoning COI1mission and the SA WS board wil be invited to attend. the f!eetings. u.

. With this report as a guide, aquifer protection and the clea nee for development of additional water resources can go hand in hand to ensure quantity and quality for San Antonio's future water supply.

68 WORK SESSION OF THE CITY COUNCIL, SITTING AS THE CITY COUNCIL COMMITTEE ON AQUIFER QUALITY, THE CITY OF SAN ANTONIO, HELD IN THE COUNCIL CHAMBER, CITY HALL, ON TUESDAY, JANARY 11, 1994. * * * * The meeting was called to order at 3: 15 P.M. by the Presiding Officer, Mayor Nelson W. Wolff, with the fOllowing members present: PEREZ, BILLA BURKE, AVILA, SOLIS, THORNTON, PEAK, LASON, WOLFF. Absent: McCLENDON, AYALA, ROSS. Also present were MS. DIANE RATH, VICE CHAIRPERSON, SAN ANTONIO WATER SYSTEM; OTHER MEMBERS OF THE BOARD OF TRUSTEES OF SAN ANTONIO WATER SYSTEM; MR. PHIL GARY, CHAIRM OF THE PLANING COMMISSION; and MR. MICHAEL McMAHON, CHAIRM OF THE ZONING COMMISSION.

Mayor Wolff provided a brief background on the City Council Committee on Aquifer Quality, the 1987 study on the Edwards Aquifer, and actions taken since that report. He spoke to the committee's work plan to preserve the quality of the Edwards Aquifer water. Ms. Rebecca Q. Cedillo, Vice-President for Planning, San Antonio Water System, provided committee members with a printed handout of overhead-projected topics to be discussed, a copy of which is made a part of the papers of this work session. She briefly addressed the I-- i three main issues to be discussed today: define the issue, establish I i jurisdiction, and develop recommendations. She then addressed the geographic history of water in Texas, especially the 1,500 square miles that make up the western portion of the Edwards Aquifer. She then spoke to the physical details of the aquifer and its Recharge Zone activity. Ms. Cedillo noted that in 1987, the City Council established a policy of non-degradation of the Edwards Aquifer, and she spoke to potential problems on the Recharge Zone included in matters of transportation and development over the Recharge Zone. She noted that some 34.5 square miles of the Edwards Aquifer lies within the city limits of the City of San Antonio. She discussed the Texas Natural Resources Conservation Commission (TNRCC) Edwards Rules and Technical Guidance Manual, and spoke to the impact of the Edwards Underground Water District (EUWD) and various studies that have been made of the Edwards Aquifer. She then spoke to the 1987 Perspectives Report and its various segments and

( 1) 69 ramifications, and the two City Council Resolutions endorsing the concept of Edwards Aquifer non-degradation, and implementing a program to that end. Ms. Cedillo then discussed three applicable City. Council Ordinances, dealing with tertiary containment, private service lateral inspections, and adoption of Water Pollution Abatement Plans (WPAP). She then spoke to the City Code amendments that need to be made, including certain changes to Chapters 34 and 35 of the City Code. She provided committee members with a printed handout on this matter, a copy of which is made a part of the papers of this meeting. Ms. Cedillo outlined the coming stringent restrictions on stormwater abatement, and spoke to Emergency Management plans designed to cope wi th problems over the Edwards Aquifer. She then spoke to future studies that will be needed and coordinations required. Finally, Ms. Cedillo addressed her concept of the next steps that need to be taken, between now and June, and the need for coordination between the various entities involved with zoning and planning activities over the Edwards Aquifer area. A discussion took place concerning possible input into future committee meetings by various groups and individuals. Discussion then ensued concerning the lack of any current firm backup plan to provide potable water to San Antonio, should something happen to the Edwards Aquifer. A discussion took place relative to the importance of Camp Bullis military reservation to the overall Edwards Aquifer protection, and the actions deemed necessary to enact new laws and regulations to protect the Edwards Aquifer within the City of San Antonio's extra-territorial jurisdiction.

Discussion was held on the need to develop methods of cleaning up any contamination of the Edwards Aquifer, during which discussion Mr. Joe Aceves, President and Chief Executive Officer, San Antonio Water System, addressed details of one entity in Germany where underground water is pulled from the aquifer, cleaned up, and re-inserted into the underground aquifer. He spoke to the need to study the costs invol ved in possible rerouting of the transport of hazardous materials away from the aquifer Recharge Zone. Ms. Cedillo addressed the need to develop a partnership between all involved entities in a cost-sharing program to cope with these problems.

Discussion took place concerning how much of the 1987 s~udy has been implemented, and the need for a plan to cope with any accidental contamination of the Edwards Aquifer.

(2 ) 70 Discussion also ensued concerning the possible purchase of critical properties in order to maintain undeveloped open-spaces, in order to protect the Edwards Aquifer, and the need for a complete, multi-jurisdictional master plan to accomplish this. Another discussion took place on the impact of recharge-sensitive areas of the Edwards Aquifer on the City's proposed May bond-issue election, and a report by SAWS on this matter, due within the next 30 days. It was noted that some 80 per cent of Edwards Aquifer recharge is within the 100-year flood-plain. Mayor Wolff spoke to a possible agenda for the scheduled February meeting of this group, assembled today, including the matter of having the group also hear from other entities.

72 WORK SESSION OF THE CITY COUNCIL OF THE CITY OF SAN ANTONIO, SITTING AS THE CITY COUNCIL COMMITTEE ON AQUIFER QUALITY, HELD IN THE COUNCIL CHABER, CITY HALL, ON TUESDAY, FEBRUARY 8, 1994. * * * * The meeting was called to order at 3: 15 P.M. by the Presiding Officer, Mayor Nelson W. Wolff, with the following members present: McCLENDON, BILLA BURKE, AVILA, SOLIS, ROSS, THORNTON, PEAK, WOLFF. Absent: PEREZ, AYALA, LARSON. Ms. Rebecca Q. Cedillo, Vice President, PI~nning, San Antonio Water System,' provided an overview of the status of the Edwards Aquifer and explained the purpose of today's meeting. Mayor Wolff stated that the Texas Natural Resources Conservation Commission (TNRCC) would be cnducting a public hearing on March 30, 1994 for the purposes of updating its regulations, and recommended that City Council members be prepared to vote on their own recommendations at the Council's March 8, 1994 meeting, recommendations which later will be presented to TNRCC .at its March 30th hearing.

A discussion then took place concerning a March 1, 1994 TNRCC deadline. In response to a question 'by Mr. Thornton, Ms. Cedillo noted tha t SAWS would be preparing its own recommendations to be forwarded to TNRCC. Mr. Scott Hal ty, Manager, Aquifer Studies Division, SAWS, provided a current status report on the Edwards Aquifer and land-use activities over the recharge zone, within the city limits of San Antonio~ He noted that some 67 per cent of development over the recharge zone is single-family residential in nature. He then addressed the amount of commercial development over the recharge zone; the 27 known underground, single-walled storage tanks over the zone and related problems; and spoke to the fact that only about five per cent of the land-use above the zone is industrial in nature. He also spoke to a history of regulations by the four affected governmental units: the state, the Edwards Underground Water District, the City of San Antonio, and Bexar County. Mr. Halty then spoke to certain approaching deadlines of various agencies and processes required for' development over the Edwards Aquifer.

(1 ) 73 Mayor Wolff spoke to the need to do something about the single-walled underground storage tanks over the recharge zone. Mr. Mike Albach, representing the Edwards Underground Water District, spoke to the need for better protection of the recharge zone and his agency's responsibilities relating to that protection. He then addressed the effects of urbanization on the recharge zone and noted that EUWD currently is placing some 18 sampling wells over the area of the recharge zone. He then related the increase in urbanization over the zone to aquifer pollution and urged the City Council to take action to protect the Edwards Aquifer, as he spoke to EUWD's non-degradation policies. Mayor Wolff asked for a copy of the EUWD's recommendations that will be presented to TNRCC at the public hearing, so that the City might study them prior to that submission. A discussion took place concerning recharge features in the Edwards Aquifer Recharge Zone, and hydrocarbon problems from underground' storage tanks in a three-county area, including San Antonio. It was noted during the discussion that, of some 250 such tanks over the recharge and transition zones of the Edwards Aquifer in that area, 27 are in the city of San Antonio. Mr. Gene Dawson, Jr., Pape Dawson Engineering, spoke to development requirements over the Edwards Aquifer Recharge Zone, from a development engineer's point of view, and certain recommendations, a copy of which is made a part of the papers of this meeting. He then briefly outlined a history of of development regulations over the aquifer and the current process of that development, through a number of agencies. He addressed recharge features of the recharge zone of interest to a geologic engineer, and spoke to examples of responsible development, in his opinion, both residential and commercial, including the Master Water Pollution Abatement Plan, citing the Rogers property development and development of La Cantera. He then spoke to the City of San Antonio's recommendations for development over the Edwards Aquifer and suggested additional recommendations for consideration. Mr. Richard Garcia, Director of Region XIII, Texas Natural Resources Conservation Commission, spoke to the impact of TNRCC' s regulations over a 21-county area, especially the Edwards Aquifer area, and the efficacy of the staffs of both the Edwards Underground Water District and San Antonio Water System. He noted that some 88 per cent of the Edwards Aquifer falls within TNRCC's Region XIII area, and urged cooperation of all the parties involved. Mr. John Mauser, Field Investigator, TNRCC, addressed a summary of state law on water in Texas, through the Water Code, and spoke to TNRCC' s rules and regulations for development over the recharge zone, including possible changes to those rules' and regulations as a result of the scheduled hearings in the near-future. Mr. Peak posed a series of question to the various presenters on underground storage tanks, present quality of water in the Edwards Aquifer, Edwards Underground Water District recommendations to be

(2 ) 74 presented to TNRCC at the March 30, 1994 public hearing, adversee effects of urbanization on the aquifer, effects of the ' impervious cover' on recharge, and possible delegation of TNRCC authority.

ci ty Council concurred that the public should have the, time to make their own imput during next month's meeting.

City Council recessed its work session at 4: 58 P.M. in order to convene a Special City Council Meeting dealing with the proposed May 1994 bond issue. The work session resumed at 5:02 P.M.

Discussion resumed on the proposed recommendations to TNRCC. Mr. Thornton spoke to the need for growth-controls over areas outside the City of San Antonio, because of future annexation of some of those areas into the city. He expressed his opinion that the Unified Development Code should be changed to extend San Antonio's invol vement into the extra-territorial jurisdiction area (ETJ), including the need for legislative authority to allow this. Mr. Ross noted that, even if the City could increase its involvement in development in the ETJ, San Antonio would still have an impact on only nine per cent of the recharge zone. He stated his belief that TNRCC should take on more regulation of the Edwards Aquifer recharge zone areas, in place of the city of San Antonio and the Edwards Underground Water District. A discussion then . took place concerning TNRCC versus local control of development in any area. Mayor Wolff informed the Council that the next work session on water quality is set for March 8, 1994.

The work session adjourned at 5:17 P.M.

Mayor Wolff stated that, among other things to be undertaken today, the Council will be briefed with a presentation/discussion of the- San Antonio Water System/Edwards Underground Water District recommendations regarding Texas Natural Resource and Conservation Commission Chapter 313, "Edwards Rules". He further noted that the matter will come before City Council at a formal "A" Session prior to TNRCC's scheduled March 30, 1994 public hearing on this matter. . Ms. Rebecca Q. Cedillo, Vice-President for Planning, SAWS, addressed the Council's agenda today, and spoke to an overview of staff , responsibilities. Assistant Fire Chief Joe Candelario spoke to the matter of Emergency Management in San Antonio, and to plans in case of major disaster, such as a hazardous materials spill. He noted that the Ci ty of San Antonio does not have a soil-remediation process yet in place. A discussion took place concerning the possibility of hazardous materials routing and restrictions, and the difficulty of its enforcement, during which Mr. Ross stated his belief that this might be easier to deal with if the restrictions and routing applied only over the Edwards Aquifer area. Ms. Cedillo spoke to a brief history of land-use activities and requirements over the Edwards Aquifer recharge zone, including ERZD zoning requirements and the - use of Wastewater Pollution Abatement Plans. Mr. Scott Halty, Aquifer Studies Division, SAWS, discussed how his office addresses rezoning requests over the recharge zone, and he spoke to the three various stages of stormwater abatement. He then spoke to areas of such regulation, where local regulations often are more stringent than state regulations. He then spoke to close coordination between the San Antonio Water System and both TNRCC and

( 1)

77 EUWD on matters such as development over the recharge zone. Mr. Jay Aldean, Stormwater Department, SAWS, spoke to the stormwater resposibilities of his department, including the 'smoke-testing' of sewer lines over the recharge zone, and sampling procedures at spill-sites, as needed. A discussion then took place concerning the matter of Wastewater Pollution Abatement Plan review within the City of San Antonio's extra-territorial jurisdiction, and the City's possible involvement in controlling ETJ development. It was noted that TNRCC tells the City what it can and cannot do within, the City's ETJ. Mayor Wolff discussed a possible timetable for future committee meetings and City Council formal actions. Mr. Hal ty then made a presentation and led a discussion of the proposed SAWS/EUWD recommendations to be made at the TNRCC public hearing on March 30, 1994. Ms. . Danielle Milam, representing the League of Women Voters, delivered certain comments to the proposed SAWS/EUWD recommendations, including some 10 changes her group is proposing. She asked that the Committee'conservation community' bemeeting given a place on nextagenda. month's Water Quality . Mayor Wolff asked SAWS to review the 10 recommendations made by the League of Women Voters and to provide comments on those recommendations to the League. He then briefly reviewed dates and

possible agendas for future committee meetings. Ms. Cedillo spoke to suggested potential local coordination efforts, and the matter of consideeration of recommended strateegies for augmenting local responsibility and ~ jurisdiction. Ms. Cedillo also discussed the possible agenda for the April committee meeting, the May public hearing, and the City Council formal vote two weeks later. Mr. David Pasley, Director of Planning, discussed certain i tools available to potential entities in controlling development over the Edwards Aquifer reecharze zone, including annexation and 'limited-purpose annexation'.

OVERVIEW OF DRAFT REPORT ON ISSUES & IMPLEMENTATION MEASURES FOR EDWARDS RECHARGE ZONE ACTIVITIES, Ms. Rebecca Q. Cedillo, Vice-President for Planning, San Antonio Water System, reviewed committee actions to date and spoke to the commi ttee' s goal and possible future actions that might be needed in order to protect the Edwards Aquifer Recharge Zone. She reviewed and discussed jurisdictional issues, and spoke to the need to look at comprehensive water protection throughout the area. She then spoke to two 'coming Public Hearings,' the last of which begins the Implementation Program. She addressed the Basic Implementation Strategy and the some 30 recommendations to be addressed. I. REGULATORY REOUIREMENTS Ms. Cedillo discussed proposed changes to Chapter 35 of the City Code, the Unified Development Code, noting that these changes will take perhaps six months to fully implement. They include revision of the "permitted uses" table; plat approval to include all Water Pollution Abatement Plans; high concern recharge features on plats; removal and upgrade of single-wall tanks; requirement for tertiary containment on TZ; green space requirements for the ERZD (Edwards Recharge Zone District); density limits for the ERZD; significant recharge feature buffer zones; floodplain buffer zones; testing of pollution abatement structures; smoke testing; and private sanitary sewer service laterals. During discussion, she noted that the projected life of the single-wall underground tanks is about 20-25 years. She also spoke of the Special Work Group meetings, including Planning Commission, Zoning Commission and San Antonio Water System staff, to take place over the next six months, working on the five "core issues", and the. group's report back to City Council at that time. She also spoke to the

( 1)

80 'time-line' for Chapter 35 requirements. Ms. Cedillo discussed the four issues of the Stormwater Program, including the watershed management approach; revision of development standards/watersheds; pollution prevention ordinance; and clearing and grading ordinance. She spoke to this program as the maj or area of concern for possible pollution to the recharge zone, and addressed the 'time-line' for implementation of the four listed issues. She noted thát SAWS expects to receive its Stormwater Pollution Prevention Permit very soon. Discussing Chapter 34 - Water Code, she spoke to the three issues of concern, those being the well plugging program; the well abandonment program; and extension of the City's jurisdiction into the ETJ (extraterritorial jurisdiction) .

II. ORGANIZATIONAL PLAING Discussing the Texas Natural Resources Conservation Commission (TNRCC), Ms. Cedillo spoke to Chapter 313 - the Edwards Rules; Water Pollution Abatement Plans; the Technical Guidance Manual; and the Edwards Aquifer Drainage Area, including a hydrologic setting map. In the matter of Technical Improvements, Ms. Cedillo discussed five issues, including education and information; SAWS internal coordination; Significant Recharge Feature assessment flowchart evaluation; mapping of Sensitive Recharge Features; and the Global Positioning Satellite system; and a 'time-line' for their implementation. Relative to Emergency Measures, Ms. Cedillo discussed the Emergency Spill Response Plan and the Emergency Operations Plan for Pulic Supply Wells.

III. POTENTIAL ACTIVITIES. Ms. Cedillo spoke in some detail to matters for future study, including the blasting ordinance; determination of pre-development condi tions over the Edwards Aquifer Recharge Zone; and the Septic' Tank Monitoring Program.

Mayor Wolff thanked the SAWS staff for its hard work in support of these committee-of-the-whole meetings on water quality. Ms. Danielle Milam, representing the League of Women Voters and AGUA, spoke to certain recommendations of AGUA relative to the prevention of pollution of the Edwards Aquifer, calling it a health and economic issue, as well as a policy issue. She spoke to the need to preserve the natural recharge system and enforce rules for development over the recharge zone. She stated that she agrees with most of the SAWS regulatory requirements.

(2 ) 81 Ms. Milam spoke to the need for a ban on any more addi tional underground storage tanks over the recharge zone; coordination of revenue and development plans; and against any tax phase-ins for development activities over the recharge zone. She also spoke in support of acquiring of sensitive areas over the recharge zone. Mayor Wolff thanked her group for its professional assistance to SAWS.

Ms. June Kachtik, Chairperson, Open Space Comii ttee, introduced Mr. George Veni, a hydro-geologist. Mr. Veni displayed and narrated a series of slides, showing the effects of pollution on the Edwards Aquifer. He noted that a single gallon of gasoline could contaminate 10 million gallons of aquifer water.' He spoke to the need to strengthen regulations on development over the recharge zone and addressed examples of that development. He stated his belief that the Edwards Aquifer is slowly being degraded, despite good intentions and non-degradation policies. He identified development over the aquifer as the biggest pollution problem.

A discussion took place concerning the possibility that Council members might be able to tour a cave in the recharge zone area. Ms. Kachtik thanked SAWS for its report and hard work on this matter of water quality, and spoke to the need to preserve open spaces as protection for the Edwards Aquifer. She offered her committee's expertise as the Council moves to the decision-making stage.

Mr. Thornton stated his belief that San Antonio needs ' growth incentives' as well as 'growth controls', and spoke to his concern with regulating all land uses over the recharge zone. He then addressed the need to identify types of desirablre land uses over the recharge zone. In response to a question by Mr. Thornton, Ms. Cedillo discussed the Table of Permitted Uses, and identified those uses that are. harmful to water quality in the aquifer. She spoke to the need for i guidance from the City Council on any identification of recommended land uses over the recharge zone. Mr. Thornton also spoke to the need to identify desirable land uses over the recharge zone, and noted that the city of San Antonio needs to be pro-active in guiding those land uses. In response to a question by Mr. Peak, Ms. Cedillo discussed the 10-mile parameters of the "buffer zone". Mr. Peak urged the inclusion of the Open Space Committee on the commi ttee recommended for the work group study of possible actions in this area. A discussion took place concerning quality control in the recharge zone well-testing.

(3 )

82 Mr. George Rice, author of a report on the Edwards Aquifer, stated that he would be willing to work with SAWS on any questions they might have on the report findings. Mr. Ross spoke in support for Mr. Thornton 's pro-acti ve stance on recharge zone land use recommendations, and urged rapid implementation of some of the recommended new rules for development over the recharge zone. He asked SAWS for a list of priori ties for rapid implementation. Mayor Wolff spoke to the upcoming May 10th Public Hearing in the South Banquet Hall of the Convention Center, noting that the hearing will begin at 7:30 P.M. . He also noted that Bexar County Commissioners Court has been invited to join the City Council for this Public Hearing, since tax phase-in policies will be discussed that affect both governmental entities. There being no further business to come before the commi ttee, the work session was adjourned at 4: 54 P.M.

REGULATORY REQUIREMENTS CHAPTER 35 UNIFIED DEVELOPMENT CODE REVISION OF THE "PERMITTED USES" TABLE

ISSUE:

The City Council Committee of the Whole directed that a review and update of the Zoning "Permitted Uses" within the Edwards Recharge Overlay District, Section 35-3261 of the Unified Development Code (UDC) be performed.

BACKGROUN:

The Edwards Recharge Overlay District was established in 1976 in response to concerns by citizens about development on the Edwards Recharge Zone. Within the Edwards Recharge Overlay District certin uses are prohibited while others require specific City Council approval. This is due to the actions associated with the specific use being environmentally harmful in nature. Some of the uses allowed by the State on the Recharge Zone are banned within the City limits on the Recharge Zone. San Antonio's regulations are more stringent in this regard.

POLICY ANALYSIS:

Although the Permitted Uses Table was last amended in 1993, the Section has not been updated in two years. The purpose of the Edwards Recharge Overlay District is to regulate permissible activities on the Recharge Zone. Many of the "Permitted Uses" require City Council (CC) approval before they can be located over the Recharge Zone. The requirement of City Council approval allows City Council the authority to put protective measures in place in order to address site specific environmental concern, essentially adopting a site specific ordinance for each propert under consideration. This also gives City Council the authority to approve or disapprove the use. City Council sets the protective measures and bases their recommendation to approve or disapprove the land use on an environmental assessment based on staff recommendations which include San Antonio Water System.

RECOMMNDATION:

There are a number of Permitted Uses listed that should require City Council approval and others that should be prohibited from existing on the Edwards Recharge Zone that might potentially be environmentally harmfuL. It is recommended that, in order to bring more uniformity to the UDC and after evaluating the nature of the various business', the following should require City Council approval to be located on the Recharge Zone:

Batching Plant Golf course, golf driving range, pitch and Putt Amusement parks Automobile muffler sales & intallation Automobile parking lotI garage (commercial)

93' REVISION OF THE "PERMITTED USES" TABLE

Automobile parts sales Bicycle/lawnmower repair Building specialties, retail Building specialties, wholesale Cabinet or carpenter shop Clothing manufacture Contractor facilty Elevator maintenance, service Farm supplies Feed, seed, fertilizer sales Fix-it shop Freight depot Funeral home or undertaking establishment Golf course and country club Golf driving range Grain miling Lumberyard and building materials Mattress manufacturing, rebuilding Milinery manufacture Milwork and similar wç)Od products manufacture Miniwarehouse Paint and wallpaper store Pet grooming, small anials Racetrack, rodeo, and other equestrian activities Shoe manufacture Sign shop Tamale preparation, wholesale Venetian blind cleaning, fabrication Warehousing

Listed below are businesses that, due to the substances used, endanger the quality of the aquifer. It is recommended that the following land use activities be prohibited on the Recharge Zone:

Insulation manufacture & fabrication Oil well supplies and machinery manufacture Oil well supplies and machiery sales Paper ,products manufacture Poultry processing and live poultry storage completely enclosed Refrigeration equipment manufacture Shoe polish manufacture Tile roofing, water proofing manufacture Vulcaniing, recapping

94 PLAT APPROVAL CONDITIONS TO INCLUDE ALL WATER POLLUTION ABATEMENT PLANS

ISSUE:

As established in the Unified Development Code, the City of San Antonio requires a plat for land use activity within the City of San Antonio and into the extraterritorial jurisdiction. Plats are r~quired in order to insure conformance to the general plan of the City and to promote the public health, safety and general welfare, and in particular, to promote the safe, orderly, and healthfl development of the City. Because of the Water Pollution Abatement Plan's role in regulating land use activity for the protection of the water quality of the Edwards Aquifer, the City's sole source of drinking water, the Water Pollution Abatement Plan plays a role in the public health issue as well as a city development issue requiring its complete incorporation into the platting process. BACKGROUN:

The Site-Specific Water Pollution Abatement Plan which is required by the Texas Natural Resource Conservation Commission for all developments, contains an overview of the project, a geologic assessment, and a section which addresses stormwater abatement which affects drainage. In addition, it describes any potentially significant recharge features and rates them as a high, moderate, low, or no concern feature. Currently, there are four types of Water Pollution Abatement plans, a Site-Specific, Sewage Collection System, Underground Storage Tank, and Aboveground Storage Tank.

POLICY ANALYSIS:

The City Council Committee in its 1987 report 'The Edwards Aquifer: A Perspective For Local and Regional Action" directed staff to increase its involvement in reviewing development on the Edwards Aquifer Recharge Zone. The Committee expanded the task of staff to include platting activity. Language was placed in the Unified Development Code to require state approval when a sewer system is proposed for the Edwards Recharge Zone. Prior to the revision of impact fees, plat applicants were receiving approval for all Water Pollution Abatement Plans submitted before the release of the approval for a plat. Because Water Pollution Abatement Plans are now broken down into four types, one being for sewage collection systems, the Department of Plannng interpreted the language to only require approval of ths specific type of Water Pollution Abatement Plan before approval of a plat can be granted.

Some of the Plannng Commission members have expressed concerns about the omission of this information.

RECOMMNDATION:

Require approval of all Water Pollution Abatement Plans prior to plat approvaL.

95 RECORD HIGH CONCERN RECHARGE FEATURS ONTO PLATS PRIOR TO APPROV AL

ISSUE:

Plats are required in order to insure conformance to the general plan of the city and to promote the public health, safety and general welfare, and in particular, to promote the safe, orderly, and healthful development of the city. Proper development must be insured in order to protect high concern recharge features which can act as a conduit for contaminants to the Edwards reservoir. Whether high concern recharge features should be included on plats is at issue.

BACKGROUND:

The City Council Committee in its 1987 report 'The Edwards Aquifer: A Perspective For Local and Regional Action" directed staff to begin verifying that plats conform to Water Pollution Abatement Plans. From the Committee's report, a flowchart was developed which is used as a guideline in determinng whether a potentially significant recharge feature is a high, medium, low or no concern feature. Currently, Planned Unit Development (PUD) plans allow for the recording of physical features, however, plats currently do not have that requirement.

POLICY ANALYSIS:

Water - Pollution Abatement Plans are a large part of the planng process on the Edwards Recharge Zone. A large part of the process is identifying potentially significant recharge features in order to determine how they can be protected and to also determine if stronger engineering design and specifications should be used in order to protect the feature. The Planng Commission has often questioned the location of high concern recharge features which are reported by the San Antonio Water System staff to the Plannng Commission with respect to the propert. The concern of the Planng Commission are related to the location of utilty easements and development in relation to the features.

RECOMMNDATION:

Once the significant recharge feature assessment sheet is revised (3-6 months), this criteria wil be used in establishig the guidelines for determination for plat notation. Staff wil work with the Plang Commission Land Development Subcommittee to determine feasibilty of this issue.

96 REMOVAL AN UPGRAE OF SINGLE WALL TANKS

ON THE RECHARGE AN TRASITION ZONE

ISSUE:

Cllrrently, tertiary containment for underground storage tanks and double-walled piping is required on the Recharge Zone and double-walled tanks and piping are required on the Transition Zone. Several single wall underground storage tank systems were allowed to remain in place on the Recharge Zone and the Transition Zone because they existed prior to the new requirements. The issue of whether these underground storage tank systems be allowed to remain in place should be addressed.

BACKGROUN:

The Recharge Zone was first established by the State in 1970. In 1986, the Transition Zone was delineated to give added protection to the Edwards Aquifer. A study by the EP A showed that underground storage tank systems constituted a considerable containation problem. In 1989 the Texas Natural Resource Conservation Commission (TNRCC) began the systematic upgrade and removal of underground storage tanks state wide. It was discovered that many of the single wall tanks had leaked due to corrosion. There are approximately 27 underground storage tank sites on the Recharge Zone in Bexar County and 106 underground storage tank sites on the Transition Zone withn the city limits. While not all of these systems contain single wall tas and piping, approximately 66 sites contain single containent systems.

POLICY ANALYSIS:

Removal and upgrade of an underground storage ta system is a costly project. Because of the large number of single wall sites with each designated area, a program to remove and upgrade these systems would have to be phased in over a period of time to allow the owner/operator to prepare for the transition. Because of the potential for contamination to the Edwards Aquifer, as witnessed by the 1984 release of 10,000 gallons of unleaded fuel on the Transition Zone of which an unkown quantity reached the Edwards reservoir, it.is imperative tht some plan be put into place to remove them before deterioration from age takes place and fuel is released to the subsudace.

RECOMMNDATION:

Establish in Chapter 35 of the Unified Development Code the requirement for removal and upgrade of single wall underground storage tank systems on the Recharge and Transition Zones to meet TNRCC standards. A five year grace period would be allowed for systems on the Recharge Zone and a ten year grace period would be allowed for systems on the Transition Zone in order for the ownerloperator to prepare for the cost of the project.

97 REQUIMENT FOR TERTIARY CONTAINNT ON THE TRASITION ZONE

ISSUE:

The purpose of requiring a tertiary containment to underground storage tanks was to insure protection of the Edwards Aquifer in case of a release. The issue of extending the requirement of a tertiary layer of containment or equivalent technology to the Transition Zone is required because the depth to the Edwards Aquifer is shallow in some places in the Transition Zone and structures, such as water wells, can act as avenues of migration to the Edwards Recharge Zone. BACKGROUN:

In 1984 a large release of fuel occurred on what is now the Transition Zone. The fuel migrated to an Edwards well in which the casing was in poor condition. A part of the fuel entered the well through the casing and made its way down to the Edwards Aquifer. A small amount of the fuel was recovered. The Transition Zone was established in 1986 along with the requirement for double-walled tanks. In 1990, the use of pre-stressed vaults brought to light the idea of a third level of protection, including liners as another choice. In December 1991, City Council passed an amendment to the Unified Development Code which requires tertiary containment on the Recharge Zone. This requirement is stricter than the State's requirement of double-walled tanks on the Recharge Zone. The State and the City both have a requirement of only double-walled tanks on the Transition Zone.

POLICY ANALYSIS:

The incident in 1984 showed that contamination from underground storage tanks in the Transition Zone could impact the Edwards Aquifer. Most of the Transition Zone has already been developed. However, the requirement of tertiary containent or equivalent technology would inure the protection of the Edwards Aquifer. While the added cost of a third level of protection to an underground storage tank site that is being upgraded is substantial, it gives the added protection that the Committee deems necessary.

RECOMMNDATION:

Extension of the tertiary containent or equivalent technology should be required for underground storage tank sites that are either new installations or upgrades on the Transition Zone of the Edwards Aquifer. This requirement is deemed necessary to insure protection of the Edwards Aquifer.

98 GREEN SPACE REQUIREMENTS FOR THE EDWARDS RECHARGE OVERLAY DISTRICT

ISSUE:

Requiring a minium percentage of green space area per lot wil protect the quality of water entering the Edwards Aquifer. This measure not only maintains the aquifer quality, it also enhances the aesthetics of the City of San Antonio.

BACKGROUN:

Maintaining a certain amount of green space area to fiter storm water run-off is a relatively new idea with valuable benefits. A green space is a natural area consisting of grasses, trees, or both. Green space should be located in a place where stormwater run-off is prominent, such as stream banks and drainage channels. Water runng over green space area is removed of contaminants much the same way as air is cleaned through an air-fiter.

POLICY ANALYSIS:

Escalating development over the Recharge Zone necessitates the limitation of impervious cover allowable for the building of lots. By increasing the amount of green space area, the total impervious cover is decreased, thus enhancing the aesthetic appeal of the area, while simultaneously fitering stormwater run-off.

RECOMMNDATION:

Protecting the Edwards Aquifer, the sole'source of drinkng water for the City of San Antonio, is of utmost importnce to those who rely daily on the continued high quality of the water. Implementing a required green space area for lots located over the Edwards Aquifer Recharge Zone is a method of preserving the quality of water in the Aquifer.

99 DENSITY LIMITS FOR THE EDWARDS RECHARGE OVERLAY DISTRICT

ISSUE:

At issue for discussion is whether restricting the number of lots per acre permitted on the Recharge Zone of the Edwards Aquifer would provide for less impervious cover. Increasing impervious cover through development is the major point of deliberations related to water quality over the Recharge Zone. By electing to limit the maximum amount of density per acre over the Recharge Zone, the City Council wil aid regulation of development without hindering the city's growth process. The lower the density per acre, the more green space, or less impervious cover, which might be made available to filter stormwater run-off.

BACKGROUN:

Currently there are no specific regulations in place to limit the amount of density per acre over the Recharge Zone. Under the Unified Development Code, Section 35-3351, Table F, the Minum Area in square feet (for house sizes) designates the maximum number of lots possible for each zoning district.

POLICY ANALYSIS:

Information from Water Pollution Abatement Plans on fie indicate that the average subdivision consists of approximately four lots per acre on the Edwards Recharge Zone, while the maximum number of lots allowable is ten. As development over the Recharge Zone occurs, the question of whether limiting the permissible density per lot wil increase greenbelt space. By limiting the density, more green space might be made available' to fiter stormwater run-off. This fitering process is of considerable concern when attempting to maintain the current high quality of the Edwards Aquifer. This could potentially enhance the marketing potential of the propert. The issue needs to be further studied to determine if a correlation between density limits and impervious cover can be drawn.

According to Vernon's Texas Codes, Local Governent Law, a city may not govern land use outside of its city limits. This currently restricts providing density limits on the Edwards Recharge Zone in the extraterritorial jurisdiction.

RECOMMNDATION:

This issue should be studied further to allow staff to determine if restricting density limits would increase the amount of green space. It is necessary for a new Zoning designation that establishes a maximum number of lots allowable per acre over the' Edwards Aquifer Recharge Zone to limit the current density permitted inside the city limits. This zoning designation would only apply to development within the Edwards Recharge Overlay District and would set a specific maximum on the number of lots allowed per acre. It is recommended that staff furter review the issue and come back to the Committee in December, 1994 with further information and a recommendation. Outside the city limits,

100 DENSITY LIMITS FOR THE EDWARS RECHARGE OVERLAY DISTRICT changes would be required to State law governng land use activity through the state legislature. Currently under State Law, the City of San Antonio cannot govern land use outside the City Limits.

101 SIGNIFICANT RECHARGE FEATUR BUFFER ZONES

ISSUE:

Preserve and protect significant recharge areaslfeatures (SRF's) to prevent degradation of recharge water quality resulting from development on the Edwards Aquifer Recharge Zone by use of designated buffer zones around significant recharge areaslfeatures which are not located in 100 year floodplains or creeks with watersheds of greater than 300 acres draining into or across the Edwards Aquifer Recharge Zone. These buffer zones would be restricted to certain uses in addition to requiring them to be left in an unaltered state.

BACKGROUN:

As recommended in the 1987 report "The Edwards Aquifer: Perspectives For Local and Regional Action". an Open Space Policy has been developed by the City of San Antonio (December 1993). One of its goals, is to protect the quality and quantity of groundwater and surface water throughout Bexar County. The use of open space, including buffer zones, is one of the best available technologies for attining this goal.

POLICY ANALYSIS:

The Open Space Policy attempts to fulfil several goals, one of which is the utilization of open space as a means to protect the quálity and quantity of groundwater and surface water throughout Bexar County as well as an alternative means to manage stormwater runoff. This goal has two objectives: 1) Protect sensitive recharge features of the Edwards Aquifer System and 2) Promote alternative stormwater management technques that preserve the natural characteristics of the 100 year floodplain in city flood control projects and encourage the use of these technques in private development. Issues which wil need to be addressed by the implementation of this type of program are listed below:

a) Protection of SRF's to prevent degradation of recharge water quality by

utilization of buffer zones around SRF's which are not located within 100 year floodplain or creeks with watersheds of 300 acres or greater;

b) Possible economic losses incurred by owner due to restrictions placed on the land occupied by the buffer zones;

c) Potential liabilty for point source contamination due to vandalism or environmental cries;

d) Potential maintenance responsibilty for an increasing number of sites;

e) Typically, the limited amount of recharge available does not offset the risk of containation.

102 SIGNIFICANT RECHARGE FEATUR BUFR ZONES

RECOMMNDATION:

The City Council Committee of the Whole on Water Quality realizes the imediate necessity for a SRF buffer zone program. The Committee recommends the following:

~ Buffer zones wil be naturally vegetated areas around the designated SRF and . the size of the buffer zone wil be determined on an individual case by case basis;

~ That SRF'S requiring buffer zones be deed restricted to allow no development or effects of development to impinge on the SRF'S;

~ That should the liabilty of contamination or responsibilty for maintenance of the SRF'S prove to be too risky as to not being able to fully protect the quality of recharge water, then the feature should be sealed using a method which is subject to approval prior to implementation.

103 FLOODPLAIN BUFR ZONES

ISSUE:

Protection of significant recharge areaslfeatures (SRF's) to prevent degradation of recharge water quality by utilzation of vegetated buffer zones along 100 year floodplains and creeks with watersheds of 300 acres or more.

BACKGROUN:

As recommended in the 1987 report "The Edwards Aquifer: Perspectives For Local and Regional Action". an Open Space Policy has been developed by the City of San Antonio (December 1993). One of its goals is the protection of the quality of groundwater and surface water throughout Bexar County. The use of open space, including vegetated buffer zones, is one of the best available technologies for attaining this goal.

POLICY ANALYSIS:

The primary goal of the floodplain buffer zone program is to preserve and protect significant recharge areaslfeatures to prevent degradation of recharge water quality resulting from development on the Edwards Aquifer Recharge Zone by use of designated vegetated buffer zones along 100 year floodplain or creeks with watersheds of greater than 300 acres draining into or across the Edwards Aquifer Recharge Zone. These vegetated buffer zones would be restricted to certain uses requiring them to be left in an unaltered state.

RECOMMNDATION:

The City Council Committee of the Whole on Water Quality realizes the imediate necessity of a floodplain buffer zone program. The Committee recommends the following:

~ That floodplains requiring vegetated buffer zones be defined as: the 100 year floodplain as designated on the FEMA maps or creeks with watersheds of greater than 300 acres which drain into or across the Edwards Aquifer Recharge Zone; ~ That these buffer zones wil be naturally vegetated strips parallel to the floodplain in dimensions which wil be determined on an individual case by case basis;

~ That these buffer zones shall be restricted in use to only backlots of large lot single- family residential developments or designated open space areas as defined in the Open Space Policy.

104 ANALYTICAL TESTING OF APPROVED POLLUTION ABATEMENT STRUCTURS

ISSUE:

"Cumulative Effect" of development's impact on water quality and quantity over the Edwards Aquifer. Recharge Zone is a vital issue and it is imperative that this data be gathered on a timely basis. The issue is to obtain present day data used in determinng the effectiveness of approved pollution abatement structures on the quality of the stormwater run-off.

BACKGROUND:

In the 1987 report 'The Edwards Aquifer: Perspectives For Local and Regional Action". it was recommended the Edwards Underground Water District should establish a monitoring, sampling, and analysis program for approved abatement facilties associated with approved Water Pollution Abatement Plans. However, this program's full potential has not been realized and the opportnity for obtaining a very large amount of data has been lost. The opportnity for data gathering stil exists through the operators of the facilties.

POLICY ANALYSIS:

Analytical sampling and testing can be a costly operational expense. However, the small amount of sampling and testing, in both dollars and man-hours, which would be required by individual businesses or operations, would provide valuable insight on how well we are actually protecting recharge water quality and the effect of development on the Edwards Aquifer.

RECOMMNDATION:

Require the analytical testing of newly installed approved pollution abatement structures by the ownerloperators of the associated activity.

105 SMOKE TESTING

ISSUE:

Testing the Sanitary Sewer Collection System in the Edwards Aquifer Recharge Zone (EARZ) to locate defects and maintain the integrity of the system. BACKGROUN:

In 1987 the City of San Antonio was mandated by Texas Natural Resource Conservation Commission (TNRCC) to implement a program to evaluate the Sanitary Sewer Collection System every five years. The Water Resources Division of the Plannng Department was given this responsibilty. After consolidation of the water entities in May 1992, the newly formed San Antonio Water System's Stormwater Departent continued in this effort.

Two methods of inspection have been considered to accomplish this goal. Each offers some advantages over the other. Television cameras can pick up small or potential ruptures but is an expensive process. Smoke testing offers a unique benefit of testing the lateral connections to the main, as well. as the cost savings over televising. San Antonio Water System (SA WS) has been using the smoke testing method to inspect the existing main sewer lines since the program began.

POLICY ANALYSIS:

In some areas of the region, 30 TAC, Chapter 313 (Edwards Aquifer), is the only form of regulation available to protect the Recharge Zone from potential adverse activities. Consequently, enforcement by SAWS is restricted to the Recharge Zone.

A comprehensive process is needed to insure the sanitary sewer system has not been compromised. Smoke testing of the sewer lines and manholes is currently on a five year on- going inspection process. Smoke testing determines whether structural defects to mains and laterals have occurred. Examples might be off-set or open joints and cracked or crushed lines which could allow exfitration to the EAR. The testing operation does not interfere with sewer system customers. Smoke does not enter the buildings except to pass through roof vents.

When exfitration is identified, the proper agencies are notified and documentation of resolutions are forwarded to TNRCC. Responsible parties are asked to make necessary repairs. RECOMMNDATION:

Smoke testing confirms the integrity of the system. It also tests the private service laterals. It is recommended that SAWS staff work closely with TNRCC to continue the smoke testing program.

106 PRIATE SANITARY SEWER SERVICE LATERALS

ISSUE:

Permitting, Certification, and Inspection of Private Sanitary Sewer Laterals in the Edwards Aquifer Recharge Zone.

BACKGROUND:

The Texas Natural Resources Conservation Commission (formally the Texas Water Commission) authorizes the City of San Antonio to inspect construction of sewer services in the Edwards Aquifer Recharge Zone (EARZ). Inspection of private sanitary sewer laterals is performed in accordance with Chapter 313.5 (c)(9) of Texas Adminstrative Code.

An amendment was approved by the San Antonio City Council March 28, 1991, effective April 7, 1991, authorizing the San Antonio Water System (SAWS) to perform inspections of the EAR outside the City Limits and in Bexar County.

POLICY ANALYSIS:

Chapter 313 is, for some areas of the region, the only form of regulation available to protect the Recharge Zone from potential adverse activities, therefore, enforcement by SAWS is limited.

After acceptance of the Sanitary Sewer Collection System by the San Antonio Water System, the following steps are taken by the Stormwater Departent to insure compliance to Chapter 313.5(c)(9) of the 30 Texas Administrative Code.

1. Registered plumbing contractor submits permit application which is reviewed by the Director of Stormwater.

2. After acceptance and approval of plans, lateral permit is issued allowing connection to the sanitary sewer system.

3. Following completion of work, contractor then notifies SAWS Stormwater Inspector for visual inpection of connection.

4. Inspector examines lateral connection for compliance of constrction to code. Final approval is given by Director of Stormwater that all parameters were met. If lateral connection fails inspection, contractor applies for reinpection and the process is repeated until connection is approved.

Inspection of private sewer laterals confrms that sewer intallation in the EAR is in compliance with the Texas Adminstrative Code. Pollution is prevented from containating the EAR due to faulty lateral connections by contractors.

107 PRIVATE SANITARY SEWER SERVICE LATERAS

On average, 500 lateral connections as well as 250 lineal miles of sanitary sewer mains are inspected each year to insure compliance within the 175 square mile Recharge Zone.

SAWS is not authorized to inspect private sewer laterals in watersheds nort of the EARZ. The watersheds located in Bexar County, which drain to the EARZ, are comprised of 160 square miles. It is possible for contamination to occur to the EAR through these. watersheds.

RECOMMNDATION:

The inspection program adminstered by the San Antonio Water System is effective in monitoring the installation of the sanitary sewer system in the EAR. It is recommended that this program continue.

It is recommended that the program for testing and inspection of sewer laterals be expanded to include the watersheds that drain to the EAR. This opportnity can only come by way of amending the state Edwards Rules. This would insure proper installation of sanitary sewers and avoid pollution entering the EAR caused by improperly installed laterals.

108 STORMWATER COMPREHENSIV WATERSHED MANAGEMENT APPROACH

ISSUE:

The aspect of coordinating the federal, state and local programs and procedures relating to stormwater runoff into a comprehensive watershed management approach is becoming a topic of national interest among municipalities.

BACKGROUND:

Currently, within the City of San Antonio, there are numerous agencies dealing with some aspect of surface water. The City of San Antonio has been tasked at different times by these agencies with the responsibilty of adopting one or more their programs. For example, requirements from TAC §313 are imposed on the City through the Texas Natural Resource Conservation Commission (TNRCC) to cover development over the Edwards Aquifer Recharge Zone. Independent from this, are the federal requirements noted in 40 CFR Parts 122, 123, and 124 that require cities to implement stormwater management plans. In addition, the San Antonio Water System has both state and federal permits to discharge treated wastewater into area surface waters.

POLICY ANALYSIS:

The need for clean rivers and streams is obvious. The abilty to plan for water quality is becoming more important. Social infuences on water quality such as subdivision development regulations, permanent open spaces, contaminated water discharge, and natural infuences such as topography, native plants and anials all affect water quality. Some of these items are permanent and cannot be changed.

National water quality although improving, is stil short of the national clean water standards. A redirection of current efforts may be key to accomplishing this goal. The concept is to organie the stream inventory according to the watersheds that drain to them. Each new construction project can then be evaluated on the basis of the anticipated impact to its specific watershed. Watershed targets wil be established for each watershed and eventually become the standard to which all projects are judged for approvaL. Finally and most importntly, effective plannng can be done which wil establish the proper priority for future effort.

Among the different problems, the most significant to this concept is that neither land owners nor cities organied propert boundaries according to watershed boundaries. This makes the enforcement of any true watershed regulation difficult because of different jurisdictional authorities involved.

110 COMPREHENSIV WATERSHED MANAGEMENT APPROACH

RECOMMENDATION:

REVISE DEVELOPMENT STANDARS AS PART OF A COMPREHENSIV WATERSHED MANAGEMENT APPROACH

It is recommended that the City Council begin efforts toward establishing watershed management within San Antonio. The San Antonio Water System, City staff and other community leaders would begin the necessary study to present to Council, a delineation of each watershed and the following list of watershed targets:

1. Flood Control; 2. Urban nonpoint source control; 3. Urban stream protection; 4. Control of specific nonpoint source pollutants; 5. Identify and protect sensitive areas; 6. Restore degraded urban streams.

i i i REVISE DEVELOPMENT STANARS AS PART OF A COMPREHENSIV WATERSHED MANAGEMENT APPROACH

ISSUE:

The Environmental Protection Agency (EPA) has mandated, pursuant to the National Pollutant Discharge Elimination System (NPDES) regulation for storm water discharges, that municipalities adopt a program to control pollution entering the municipal storm drain system originating from developed land.

BACKGROUN:

Federal requirements noted in 40 CFR Parts 122, 123, and 124 require cities to have stormwater management plans. They specifically require medium and large sized municipalities to apply for an NPDES permit to operate a storm drainage system.

POLICY ANALYSIS:

The permit requires that any permitted city operating a storm drainage system must have as part of the storm water management plan regulations that impose water quality based controls for new development. The regulations, when adopted, wi1limit the amount of pollution that may enter the municipal storm drain system from newly developed or redeveloped property.

EP A studied urban areas thoughout the country. They determined that all of these areas in some way or another contribute to an increase of pollution of our country's river and streams. This increase in pollution is the target EPA is trying to reduce or eliminate.

RECOMMNDATION:

It is recommended that the San Antonio Water System and City staff study and recommend to Council the appropriate measures to undertake to control, and reduce pollution resulting from urbaniation. It is furter recommended that the concept of Comprehensive Watershed Management discussed earlier, be employed to accomplish this task. Implementation of these controls would result in amendments to the Unified Development Code. It is also recommended that staff return in December, 1994 with an update and status on the EPA Stormwater Permit requirements and the feasibilty of this issue.

112 POLLUTION PREVENTION ORDINANCE

ISSUE:

The Environmental Protection Agency (EPA) has mandated, pursuant to the National Pollutant Discharge Elimination System (NPDES) regulation for storm water discharges, that municipalities adopt adequate legal authority to prohibit the pollution of a municipality's storm Preventiondrainage system. In order to comply, the Ordinance.City of San Antonio wil propose a Pollution . BACKGROUN:

Federal requirements noted in 40 CFR Parts 122, 123, and 124 require cities to have stormwater management plans. They specifically require medium and large sized municipalities to apply for an National Pollutant Discharge Elimination System (NPDES) permit to operate a storm drainage system. One of the conditions of the permit is that any permitted city operating a storm drainage system must have or adopt "adequate legal authority" to control discharges to its system.

POLICY ANALYSIS:

The federal code in discussing the "adequate legal authority" falls short of requiring a city to adopt a local permit to control discharges. Therefore, an ordinance that prohibits any discharge of harmful material either to the public health or the environment has been proposed to EP A to meet the minium requirements. This ordinance is known as the Pollution Prevention Ordinance (PPO).

The advantages to this approach are severaL. It should first meet the minium requirement of the permit obligation. The proposed ordinance could also be used as a tool for public education and understanding and it could provide 'a control of the obvious discharge of harmful materials to our future water supply.

Specific local limits have not been established for the discharge of known harmful materials. The City Industrial Waste Ordinance, which deals with pretreatment of the sewer waste stream may in the future act as a model for a revision to the PPO proposed herein.

RECOMMNDATION:

It is recommended that the Pollution Prevention Ordinance be passed by the City Council by summer of this year.

113 CLEARIG AND GRADING ORDINANCE

ISSUE:

The Environmental Protection Agency has mandated, pursuant to the National Pollutant Discharge Elimination System (NPDES) regulation for storm water discharges, that municipalities adopt a program to control erosion and other material discharge from construction sites.

BACKGROUND:

Federal requirements noted in 40 CFR Parts 122, 123, and 124 require cities to have stormwater management plans. They specifically require medium and large sized municipalities to apply for a National Pollutant Discharge Elimination System (NPDES) permit to operate a storm drainage system. One of the conditions of the permit requires any permitted city operating a storm drainage system must have as part of the storm water management plan a program to control erosion from construction sites within the city's jurisdiction.

Construction within San Antonio follows the normal permit process. Each contractor applies for a building permit though the City Building Inspections Dept. prior to construction of actual improvements in the ground. Clearing or grading a site has previously been an unregulated part of this process and is performed by land owners at wil.

POLICY ANALYSIS:

The building permit process closely follows the Uniform Building Code. Modification to this permit to include a clearing or grading specification is not recommended. However, a new clearing and grading ordinance is proposed to fulfil the requirement from the EP A and simplify the transition of ths requirement into the contracting community. The ordinance establishes a local permit be required prior to any clearing or grading activities can occur on any site with the City Limits of San Antonio.

The advantages to ths approach are severaL. First, it meets the minium requirement of the NPDES permit obligation. Second, the proposed Jrdinance wil not require much more than is currently required directly from contractors by the EP A. Contractors are also currently required to apply directly to EP A for a separate permit on new construction. The approach to this ordinance "piggy backs" the EP A requirement for contractors so they are not excessively delayed in start time to begin construction. Third, the ordinance works in conjunction with EP A to make enforcement of the local permit and the EP A's requirement simultaneous. EP A also becomes a backup enforcement mechanism for the permit established by the proposed ordinance.

The major disadvantage of this ordinance is that it wil add to the cost of construction. Required site erosion control plans wil be costly to do and must be done by registered engineers. Inspections and plans checking service fees from the City wil be borne by the owner or contractor, and additional delays in construction wil also result from this new process.

114 CLEARIG AND GRADING ORDINANCE

RECOMMNDATION:

It is recommended that the Clearing and Grading Ordinance be passed by the City CounciL. The timing for this requirement to be in compliance with the NPDES permit is unkown at this time. It is anticipated that the City wil have one year from the time the permit is issued by EP A to the City to be incompliance.

115 CHAPTER 34 -- WATER CODE WELL CLOSUR PROGRA

ISSUE:

The San Antonio Water System (SAWS), Water Quality Division, has been designated to interpret, modify and monitor the operation of a water well program to assist in the protection of the supply of drinking water for the health and welfare of its customers.

BACKGROUN:

The closure of water wells that are of poor construction andlor are abandoned is being emphasized in modern regulations designed to protect ground water supplies. The Safe Drinking Water Act, Well Protection Rule, addresses potential pollution hazards within a five-mile radius of infuence of public water supply wells. Such hazards as underground petroleum storage tanks, industrial and solid waste sites, private sewage facilities and abandoned wells are identified and monitored relative to any real or potential impact on the public water supply.

The San Antonio City Code gives the Water Quality Division authority to identify abandoned water wells and to communicate the requirement to plug such wells to their owners. A second mechanism the Division has to accomplish, in addition to the plugging of abandoned water wells, is to make inspections of propert plats submitted to the City. The plat wil be disapproved until the plugging of any and all abandoned water wells on the platted property is completed.

Another mechanism for closing abandonedl substandard water wells is the internal procedure that utilizes the Water Well Declaration Form, FNOOl-3 (Attachment A). Potential customers for SAWS water service are required to sign this form to declare the presence or absence of a water well on the propert for which they are making application for water service. If the applicant has a well on his property, he is allowed 60 days after receiving water service from SAWS to plug the well.

POLICY:

The San Antonio Water System Board of Trustees and the SAWS Water Quality Division, .as its agent, is designated in the San Antonio City Code as being responsible for monitoring the plugging, repair and constrction of water wells. The code, however, is not specific in providing details for all operations of the well program. For example, abandoned water wells are to be closed "with such materials and in such manner as, in the judgment of the Board, wil prevent the pollution and containation of the City's water supply. . .", Sections 34-74. The water well program currently in operation also adheres to the rules for water well drilers as defined in 31 Texas Administrative Code, Chapter 287 and the Rules and Regulations for Public Water System promulgated in 1992 by the Texas Water Commission (now the Texas Natural Resource Conservation Commission, TNRCC).

117 WELL CLOSUR PROGRA

RECOMMNDATION:

In order to faciltate the closure of substandardl abandoned water wells throughout Bexar County, it is recommended that amendments to Chapter 34-- Water Code be developed to:

1. Approve the Water Well Declaration Form (Attachment A). Designed to establish the presence of a well on the property;

2. Approve the proposed SAWS Customer Service Agreement that is required by TNRCC (Attachment B). This instrument wil faciltate the acceptance of new regulations by the water service applicant by conveying the atmosphere of a partnership for protecting water quality;

3. Approve amendments to Chapter 34 outlnig specific requirements for well.

123. WELL ABANDONMNT PROGRA

ISSUE:

Chapter 34 of the City Code requires land owners within two hundred feet of an established water supply line, to connect to that line. Some land owners are reluctant to discontinue their use of an existing well that does not met standards at the time of connection.

BACKGROUN:

Since 1959, wells that are approved by the Department of Health more than 100 feet deep and meet with all water standards required for health may continue use of that well. All other wells are considered substandard. As the Water System has grown over the decades, some owners are reluctant to give up on their wells even though they are now connected to the system.

POLICY:

If an applicant has a well on his propert, he is allowed 60 days after achieving water service from San Antonio Water System (SAWS) to plug the well. Many applicants have asked for variances to continue use of the well for hardships, non-potable uses and assurances of another source of water for domestic need. Staff has worked with many applicants in this regard and sees the necessity in formalizing the variance process to insure that quality controls to protect the System are in place for the time period that the well is in use. The variance procedure wil require periodic testing and a definite time period for closure.

RECOMMNDATION:

Amend Chapter 34 of the City Code to require well closure upon tie-in to San Antonio Water System lines. Provide a strict variance procedure if warranted for the applicant.

124 EXTENSION OF JUISDICTION INTO EXTRATERRITORIAL JUISDICTION

ISSUE:

With the increases in development that has occurred in recent years, regulating activities over the Recharge Zone has become an important issue. Through ordinances and criteria found in the Unified Development Code, the City of San Antonio has established jurisdiction within the City Limits that allows for protective measures for the Edwards Aquifer. That same level of protection by the City of San Antonio does not occur within the 5 mile area extending past the city limits known as the Extraterritorial Jurisdiction (ETJ).

BACKGROUN:

Of the 1,500 sq. miles of the Edwards Aquifer, approximately 175 sq. miles (11.6 %) lies in Bexar County and accounts for only 10% of the annual recharge. Approximately 34.5 square miles (2.3%) of the recharge zone is within the city limits of San Antonio.

The area 5 miles outside the city limits known as the ETJ allows for future expansion of the City through annexation. The City of San Antonio is limited in their abilty to prevent direct theats to water quality that occur within the ETJ on the Recharge Zone. Zoning, intended to protect the health, safety and welfare of the community by regulating land use, is limited to within the city limits. Subdivision codes, which extend into the ETJ, cannot regulate land use and provide limited protection to the Aquifer. Their purpose is to provide for the orderly division of land and to provide adequate infrastructure in accordance with community standards such as streets, sidewalks, water, sewer, and drainage.

The Texas Water Code §26.177 (Water Pollution Control Duties of Cities) allows for water pollution control and abatement programs for the entire City including the ETJ thus allowing standards set by the City for the protection of the Aquifer to apply to the area within the city limits and the ETJ.

POLICY ANALYSIS:

Current measures used in Chapter 35 to extend Zoning authority into the ETJ and to increase the abilty of the City to protect the Aquifer through land use, annexation would be required. Zonig and subdivision regulations are very restrictive in their application. Strengthening the protective measures on the Recharge Zone could be accomplished by modifying the Subdivision codes to increase standards on drainage improvements, pollution abatement, and floodplains, however, each component could take several years for implementation.

125 EXTENSION OF JUISDICTION INTO EXTRATERRITORIAL JUISDICTION

As an alternative, the Texas Water Code §26 .177 allows the City to extend its authority into the ETJ for water pollution control and abatement programs thus allowing for a standardized program addressing storm sewer discharges and urban runoff from rainwater for areas on and off the Recharge Zone. Protecting the quality of water entering the Aquifer and the water entering the drainageways affecting downstream users provides a realistic goal for the local and regional community.

Adoption of an ordinance to include Texas Water Code §26.177 within the City's regulatory powers would allow for a master plan that would include both the City and the ETJ in addressing the water pollution and abatement issues involving the water quality of the Aquifer.

The time involved for review and approval by the Texas Natural Resource Conservation Commission and the establishment of programs could become a lengthy process.

RECOMMENDATION:

Protection of the Aquifer is a local and regional concern. Adoption of an ordinance to develop and execute a reasonable and realistic plan addressing water pollution control and abatement programs through the Texas Water Code §26.177 would provide an avenue for the City to address the water quality issue on a larger scale.

ORGANIZATIONAL PROGRAMMING . i

1-

TNRCC CHAPTER 313 EDWARDS RULES

ISSUE:

The purpose of the Edwards Rules, Chapter 313, is to regulate activities having the potential for causing pollution of the Edwards Aquifer. The "Rules" address those activities that have direct threats to water quality. This issue requires continued monitoring of the "Rules" to promote strict but fair requirements to insure continued protection of our sole source of water.

BACKGROUN:

The Edwards Rules have been in place since 1970. They have been revised and improved to address specific prohibited activities, wastewater collection, construction, storage tanks, protection of recharge features, and water pollution abatement plans. In addition, the "Rules" have been amended to include definition of a geographic area adjacent to the Recharge Zone, called the Transition Zone, to provide for additional protection against leakage from hydrocarbon and hazardous substance storage facilities.

POLICY ANALYSIS:

The Texas Natural Resource Conservation Commission (TNRCC) is directed by the Texas Water Code (§26.046) to conduct annual public hearings in the Edwards Region, or any other county where requested by the county commissioners. The last public hearing held in 1992, provided many recommendations and changes to the "Rules". The March 30, 1994 public hearing convened 42 speakers with comments related to specific sections of the "Rules" as well as general statements regarding enforcement, pollution control and agency coordination.

By amending the "Rules" to strengthen its protective goal for the Recharge Zone, TNRCC and all involved utilties must coordinate and cooperate on the procedures for implementation. The criteria to be developed should include considerations for timing, abilty to pedorm and provide pedormance standards for specific requirements related to facilties and for infrastructure. The "Rules" should be flexible to consider technological as well as institutional changes that can occur. Chapter 313 should also continue to consider the role of local entities but be mindful of the needs of counties that are without land use regulatory authority.

Chapter 313 is, for some areas of the region, the only form of regulation available to protect the Recharge Zone from potential adverse activities. Enforcement of the "Rules" is in the jurisdiction of the San Antonio office TNRCC staff (two persons) with the assistance of local entities with the Edwards Recharge Zone (ERZ). Because enforcement of Chapter 313 is limited, it is necessary to empower the local TNRCC staff with authority to issue citations for violations. Enforcement is key to the success of the "Rules". Their restrictiveness is limited only to how well they are followed.

129 CHAPTER 313 EDWARDS RULES

RECOMMNDATION:

Continued review of the "Rules" amendment process is necessary to insure regional applicability of standards for protection. This process wil be in the form of communication with both the local and Austin offices. The communication wil provide for monitoring amendments promulgated by TNRCC with review by the City of San Antonio. Amendments designed to strengthen' the "Rules" wil be submitted for public comment by TNRCC prior to adoption.

The City of San Antonio wil remain committed to following though on the recommendations forwarded to TNRCC and provide updates on their status for inclusion in the "Rules".

130 WATER POLLUTION ABATEMENT PLAN

ISSUE:

The Edwards Rules require that a Water Pollution Abatement Plan (WP AP) be submitted for new development on the Edwards Recharge Zone. The WP AP process is the heart of the Edwards Rules. Review and comment on the plans is done by Texas Natural Resource Conservation Commission (TNRCC) staff in cooperation with San Antonio Water System (SAWS) and Edwards District personneL. Coordination of this comment and review system is key to insuring local input to provide the strictest requirements possible for this area.

BACKGROUN:

In 1987, the City Council Committee report recommended an increase in the City of San Antonio's role in reviewing Recharge Zone activities. Since that time, zonig case approval has been conditioned to WPAP adoption. In addition, the City's role in WPAP review and comment has expanded to include field visits, meeting with the applicant, and proposals for modification.

POLICY ANALYSIS:

The WP AP has grown in importance from a report of a few pages to extensive plans based on the nature of the proposed project. Applicants must submit site plans, geologic assessments, construction sequencing, description of the proposed development, wastewater and stormwater volumes, pollution prevention measures and methods of protecting significant features.

Coordinating the review of these documents is crucial to insuring that protective measures within the City of San Antonio's jurisdiction are implemented. Recommendations made during the analysis become part of the special conditions. A cooperative spirit between the reviewing entities has fostered a strong team for dilgent oversight of land use activities. Although they do not always agree, the inter-agency communication has improved land use assessments and recharge feature evaluation.

The physical and budgetary limitations placed on the TNRCC staff is further evidence of the need to continue ths collaboration. SAWS, working through the City of San Antonio's Departent of Building Inspections, has attempted to assist TNRCC in enforcement of building standards related to issuance of Certificates of Occupancy. Final assessments and recommendations are submitted to the Zoning Commission, the Plannng Commission and the City Council in the decision-makg process as conditions for approval. These final statements are then forwarded to the Texas Natural Resource Conservation Commission. ,

131 WATER POLLUTION ABATEMENT PLAN

RECOMMNDATIONS:

Continued cooperation between the City of San Antonio and TNRCC staff in the review of Water Pollution Abatement Plans is key to establishing and protecting environmentally sensitive areas. The process of monitoring development over the Recharge Zone begins with the submittal of the Water Pollution Abatement Plan. The City's input during the assessment of the proposed uses also aids in making further recommendations in the local development process of zoning and subdivision regulation.

132 TECHNICAL GUIANCE MANAL

ISSUE:

The intent of the Edwards Aquifer Protection program is to regulate activities having the potential for causing pollution of the Edwards Aquifer. The Texas Natural Resource Conservation Commission (TNRCC) has developed and distributed a "Techncal Guidance Manual" for use by applicants to help them prepare their material according to Chapter 313 Edwards Rules. As a tool, the "Manual" is a good reference point for establishing regional development standards over the Recharge Zone.

BACKGROUN:

Since 1970, the Edwards Rules have undergone revision and update to meet even stricter standards. As part of that evolution, TNRCC has developed a "how to" users' guide. The Manual provides step-by-step suggestions for compliance in the areas of applications, Water Pollution Abatement Plan (WP AP) requirements, organied sewage collection system criteria, petroleum tanks, temporary sedimentation and erosion control structures and permanent stormwater pollution control requirements.

POLICY ANALYSIS:

By providing a set of examples, the "Techncal Guidance Manual" sets out to educate and inform applicants of the specific requirements in Chapter 313. The document goes a step further by commenting on effectiveness and standards of environmental feature protection.

Protection guidelines in the form of narratives and diagrams ilustrate temporary erosion and sedimentation structures to be used during construction as well as permanent stormwater pollution control requirements. These features are "best management practices" promoted by TNRCC as prudent environmental safeguards. The manual also outlines a resident education program addressing ilegal household and industrial waste discharges into storm sewers. Finally, it clearly delineates residential areas within the Recharge Zone.

The "Techncal Guidance Manual" expands the intent of the Chapter 313 Edwards Rules to assist the regulated communty. The "Manual" is a key first step in establishig a regional approach to pollution education, monitorig and abatement.

RECOMMNDATIONS:

Promotion and use of the "Techncal Guidance Manual" wil establish a means to address some of the concern which arise from development over the Recharge Zone. It can possibly aid in future Edwards Rules changes and, if successful, can be adopted as part of the "Rules". The

"Manual" can also aid local entities to develop their own guidelines for storm water abatement.

133 DRAINAGE AREA

ISSUE:

The Drainage Area is a segment of the Edwards Plateau where rain feeds streams draining toward the aquifer itself. The majority of the streamflows originating in this area and the hil country, as well as runoff from the imediate area, reach the exposed openings of the Recharge Zone and channel into the aquifer. As a conduit for potential recharge, this area must also be protected.

BACKGROUN:

The Drainage Area of the Edwards Aquifer remains a primary concern. It is a vast, large area covering a major portion of the Edwards Plateau. This issue was introduced in the 1987 report "The Edwards Aquifer: Perspectives For Local and Regional Action" report as an area of concern. While activities on the Drainage Area can dramatically infuence the Aquifer, its size renders it beyond the scope of the City to regulate.

POLICY ANALYSIS:

The Texas Natural Conservation Commission (TNRCC), under the authority granted it by the Texas Water Code, is the only entity which can adequately safeguard the Drainage area.

During the TNRCC's annual public hearing held on March 30, 1994 to consider comments on Chapter 313, Edward Rules, the City again requested establishment of a Drainage Zone. This zone would have boundaries similar to the catchment area where most waters from creeks and streams would channel into the Recharge Z"One for replenishment. The Drainage Zone would be governed as the Recharge Zone, especially in the areas of underground storage tanks, sewer main and lateral construction and inspection as well as stormwater abatement.

RECOMMNDATION:

Continue to urge the TNRCC to formally establish the Drainage Zone as part of the Edwards Aquifer system with thee years and with requirements similar to the Recharge Zone.

134 TECHNICAL IMPROVEMENTS EDUCATION AND INFORMATION

ISSUE:

Water is a commodity that is easily taken for granted especially in the Edwards Aquifer Recharge Zone. Education and information about the Edwards Aquifer Recharge Zone should be encouraged among the Homeowner Associations, Commercial Developers, and the general public located on or traveling on the Edwards Aquifer Recharge Zone to insure continued protection of our sole source of water.

BACKGROUN:

Increased awareness and protection of the Edwards Aquifer has evolved since the Texas Legislature recognized the significance and uniqueness of the Edwards Aquifer in 1959. The Edwards Rules, Chapter 313 in place since 1970 and revised and improved upon over the years to address issues relevant to the protection of the Edwards Aquifer requires a Water Pollution Abatement Plan (WP AP) when plannng regulated development over the Edwards Aquifer. The Water Pollution Abatement Plan provides developers with the necessary framework to plan their projects within the guidelines of the Chapter 313 rules and regulations. Annual public hearings are provided for in the rules giving an avenue to update and revise the Chapter 313 Edwards Rules with the most recent hearing being March 30, 1994.

POLICY ANALYSIS:

One in four new housing units built in Bexar County are being built on the Edwards Recharge Zone (ERZ). With increase in development on the ERZ, more of the general public wi1live, work, shop, and drive on the ERZ thus providing an opportnity to educate the public on the importance of protecting the quality of the water in the Aquifer.

The Texas Natural Resource Conservation Commission (TNRCC) has been designated by the Texas Legislature as the regulatory agency for regulating development over the Edwards Recharge Zone. Water Pollution Abatement Plans are required for regulated development over the Recharge Zone. Water Pollution Abatement Plans described in Chapter 313.4 of the Texas Adminstrative Code defines regulated development as "Any residential subdivision or any public or private industral, commercial, or multi-family construction, with the exception of residential subdivisions in which every lot is larger than five (5) acres and no more than one single-family residence is allowed on each lot. Industrial, commercial, or multi-family construction is considered a regulated development regardless or'lot size" . Water Pollution Abatement Plans currently require the applicant to abide by the rules and regulations set forth in Chapter 313.4 when developing a site. To be included in the WPAP is detailed information about the present status of the site, what wil occur during development and a description of the site upon completion of the project. Currently, San Antonio Water System provides educational materials relating to water quantity, quality, and environmental safety.

136 EDUCATION AN INORMATION

The TNRCC is directed by the Texas Water Code (§26.046) to conduct annual public hearings in the Edwards Region, or any other county where requested by the county commissioners for recommendations on changes to the Rules. By including a requirement into the Chapter 313.4 Rules requiring an applicant provide for educational and informational materials, awareness of the Edwards Aquifer and its unique characteristics is amplified. By educating the public who live, work, shop or drive on the Edwards Recharge Zone, they become more aware and conscientious of the need to protect the Aquifer.

RECOMMNDATION:

Recommend to TNRCC that Chapter 313.4 of the Edwards Rules require the applicant to provide educational materials and information on the Edwards Aquifer upon completion of any regulated activity that satisfies the Water Pollution Abatement Plan requirements. A plan for dissemination of materials and information should be included in the WP AP.

San Antonio Water System should continue their educational programs and look for ways to further educate the public on water quality and quantity issues. ..

137 SAN ANTONIO WATER SYSTEM INTERNAL COORDINATION

ISSUE:

The issue of development is further complicated when more than one department within an agency needs to either review, or study the impact of proposed development. At times, there is a need for personnel from the Stormwater Department to review and comment on plans for certain projects.

BACKGROUND:

Part of the EP A Stormwater Management Plan (SMP) requires that new development should proceed in conformity with the local municipality's development and redevelopment standards. These standards wil exist to control and limit the amount of pollutants that may enter the municipal storm drain system. These standards wil ultimately be reviewed and accepted by the Region VI office of EP A as "in conformance with" permit conditions. Their authority over this issue is through the National Pollutant Discharge Elimination System (NPDES) stormwater permit that wil be issued to the City of San Antonio later this year.

POLICY ANALYSIS:

The Texas Natural Resource Conservation Commission (TNRCC) is directed by the Texas Adminstrative Code (§313.4) to approve Water Pollution Abatement Plans (WPAP) submitted for development over the Recharge Zone. This activity is being performed by personnel from the San Antonio Water System (SAWS) Division of Aquifer Studies. The WPAP also essentially addresses the stormwater requirement imposed by the EP A through the City's SMP. So it is conceivable that these same plans when submitted by the developer, wil also include Stormwater review and comment in conformance with the requirements imposed by the SMP.

In addition, certin projects proposed for the Recharge Zone present unique engineering problems. The Division of Aquifer Studies and the Stormwater Departent wil need to consult with one another to allow for additional input to determine the effectiveness of proposed pollution abatement plans.

RECOMMNDATION:

This issue is noted here to identify an internal adjustment to alert applicants when new plans are submitted to SAWS for approval. SAWS wil work to insure that ths internal distribution of plans and reviews do not delay the certification process.

138 SIGNIFICANT RECHARGE FEATUR ASSESSMENT FLOWCHART EVALUATION

ISSUE:

The current significant recharge feature assessment flowchart which was developed and implemented as a result of the 1987 report "The Edwards Aquifer: Perspectives For Local and Regional Action" is in need of revision. There are several situations which arise during geologic assessments where the current flowchart is not flexible enough to provide adequate assessments of potentially significant recharge features which are observed in the field. The issue is to modify the current flowchart so that it be more flexibie and wil provide an assessment which addresses the situation more closely.

BACKGROUN:

In the 1987' report "The Edwards Aquifer: Perspectives For Local And Regional Action", a flowchart was developed to aid in the assessment of significant recharge features. This flowchart has been used in the development of Water Pollution Abatement Plans for the past 7 years. Recently, the Texas Natural Resource Conservation Commission has spearheaded a change in . the application and development of Water Polluticn Abatement Plans and several discrepancies in the flowchart have been discussed. Through these discussions, the need for a revision of the current assessment flowchart has been voiced.

POLICY ANALYSIS:

The current flowchart should be evaluated and modified as warranted by a committee of individuals currently involved in the development and review of Water Pollution Abatement Plans .

RECOMMNDATION:

Require the analysis and development of a new flowchart to adequately address current situations experienced during the preparation and review of Water Pollution Abatement Plans.

139 MAPPING OF SENSITIV RECHARGE FEATURS

ISSUE:

The unavailabilty or lack of accurate and up-to-date data is a problem faced by local and regional decision makers. Continued mapping of sensitive areas in the Recharge Zone to provide an overview andlor pattern of geologic features is essential to the responsible manageme~t of the Edwards Aquifer.

BACKGROUND:

The Edwards Aquifer area is a karst formation with a Recharge Zone extending from Central Hays County to northern Kinney County. Karst aquifers typically have a large number of caves, sinkoles and other features that function as groundwater flow conduits for recharge.

In 1987, the City Council passed Resolution 87-47-72 which endorsed and formalized the City of San Antonio's non-degradation policy toward groundwater protection for the Edwards Aquifer. The resolution recognied that a comprehensive regional and local groundwater program was needed. A complete and accurate map identifying sensitive areas is an important element in developing local andlor regional plans for Aquifer protection.

Currently the Edwards Underground Water District and the San Antonio Water System each maintain and continually update separate databa3es of sensitive recharge features in Bexar County.

POLICY ANALYSIS:

Mapping of significant recharge features is crucial to the knowledge needed to evaluate the recharge zone. A reliable database can be a useful tool to use in implementing policy decisions relating to water quality issues. Development frequently alters or covers up features that could have been identified and put into a useful database. As more data is accumulated, patterns become apparent and give us a better understanding of the network of karst features that are typical of the Edwards Aquifer. This inormation might allow regulating activities to avert potential adverse activities over the Recharge Zone, even in areas where development has taken place and changed the land surface.

The abilty of local and regional officials to make the wisest use of limited funds and staff time in implementing policy issues depends on the availabilty of current accurate water data. One agency needs to be identified as the repository or "clearing house" with each agency submitting data. Methods of gathering data, accuracy standards, and any associated costs need to be agreed upon. A liaison from each agency would interact closely with the lead agency to assure accuracy and usefulness of data. The cost of a cooperative program would depend on the commitment made by each agency.

140 MAPPING OF SENSITIV RECHARGE FEATURS

Non-degradation of the Edwards Aquifer is a combined effort. With each agency sharing an accurate and useful database on the Aquifer sensitive recharge features, informed decisions can be made with assurance.

RECOMMENDATION:

Mapping of significant recharge features of the Edwards Aquifer is an important tool in implementing the City's non-degradation policy on water quality. A central authority with the responsibilty of maintaining a reliable and accurate database, interaction between agencies, agreement on a reliable method of collecting data, and shared administrative costs, is essential to a successful mapping program.

The Edwards Underground Water District currently has a database. However, with limited manpower, changes in management and responsibilties to other counties, their abilty to increase and maintain that database may be diminished.

The San Antonio Water System (SA WS) is continually updating their database on Aquifer sensitive recharge features. By designating the San Antonio Water System as the lead agency, they would bring to the program the stabilty and resources of a utilty, an established network of cooperation with other agencies, an abilty to provide SAWS personnel to the effort, and a centralized location thus making SAWS an excellent choice.

The local community needs to make informed decisions on future water needs. Mapping of sensitive recharge features is an important tool in accomplishing that task.

141 GLOBAL POSITIONING SATELLITE SYSTEM

ISSUE:

The provision for a Global Positioning Satellte system for locating Significant Recharge Features (SRF's) and to map the Edwards Aquifer Recharge Zone and Transition Zone would allow for taking advantage of this information and putting it to good use.

BACKGROUND:

In the 1987 report 'The Edwards Aquifer: Perspectives For Local and Regional Action". the Edwards Underground Water District (EUWD) became the central authority in mapping the Edwards Recharge Zone and locating SRF's. The program has been successful in generating maps of the Edwards Aquifer. Several agencies are involved in gathering substantial knowledge of the Recharge Zone characteristics. These agencies are:

* Unìted States Geological Services (USGS) * The Bureau of Economic Geology, University of Texas at Austin * Edwards Underground Water District (EUWD) * San Antonio Water System

POLICY ANALYSIS:

The Edwards Aquifer is a unique system which requires extensive mapping to aid in understanding its intriGate functions. The increal)ed concern regarding the cumulative effect of development over the Aquifer necessitates not only a good working knowledge of the internal functions of the Aquifer, but adequate mapping of SRF's as welL. The amount of data which is submitted at each site is assessed for development and should be utilized to its fullest potentiaL.

The mapping of Significant Recharge Features is of vital importnce in establishing the exact location and subsequent protection of those SRF's. Mapping wil be used as a guide to implement the Texas Natural Resource Conservation Commission recommendations .or any other agencies' recommendations concernng development over the Recharge Zone. Mapping wil be used in helping to direct the development over the Recharge Zone.

Mapping is the basis for developing the knowledge necessary for land development and management planng to protect the Edwards Aquifer. The technques and methods used are importnt aspects of the mapping process and have to be clearly defined. The methods for identifying, describing and quantifying Significant Recharge Features must be implemented in a manner based on sound geological and engineering practices. Mapping of Significant Recharge Features provides crucial knowledge needed to protect the Edwards Aquifer Recharge Zone.

142 GLOBAL POSITION SATELLITE SYSTEM

RECOMMNDATION:

The use of a Gobal Postioning Satellte System by SAWS wil help in mapping the Edwards Recharge Zone, the Transition Zone, and locate Significant Recharge Features such as caverns, sinkoles, faults, and various structures more accurately. It wil help in the plannng and protection of Significant Recharge Features from development over the Recharge Zone. . It can also be used to locate abandoned wells, underground storage tanks, and sewer lines.

143 EMERGENCY MEASURES EMERGENCY SPILL RESPONSE PLAN

ISSUE:

The primary role of the San Antonio Water System (SA WS) in an emergency is to protect and miniize the impact of an uncontrolled release or spil to the City of San Antonio's water resources and to the various utilties the system oversees or manages. An Emergency Operations. Plan (EOP) which covers procedures for large scale emergencies (ranging from natural disasters to domestic emergencies) is currently in place for the City of San Antonio.

BACKGROUND:

Under the EOP plan, the San Antonio Water System's primary responsibilties wil be the provision of an emergency water supply for all types of emergency situations and the restoration of normal water service with a minial delay following the emergency. It provides for certain actions by the San Antonio Water System to assure the continued supply of water to the maximum extent possible. According to the plan, the San Antonio Water System wil work together with the City of San Antonio to restore essential services to the populace.

In an effort to prepare for an emergency that pertins to a San Antonio Water System contingency , SAWS has adopted an internal Response Plan which addresses imediate response procedures. The SAWS Plan contains specific actions to be taken by the Stormwater Division and the Aquifer Studies Division. The Stormwater Division measures both the imediate impact that the spil has on the water quality and the long term affect on contamination loads and the city's abilty to meet EPA requirements regarding stormwater run-off. The Aquifer Studies Division identifies any features that are sensitive or significant to the recharge of the Edwards Aquifer at the emergency's location, and determines the best method of protecting that feature.

POLICY ANALYSIS:

Containants can reach the aquifer in a myriad of different ways. With the unregulated transportation of hazardous chemicals over the Recharge Zone, and the constant theat of ilegal dumping, there is a need for an imeriiate Emergency Response Program that designates procedures in the event of an uncontrolled release or spil.

RECOMMNDATION:

The San Antonio Water System has designated three key contact persons to be on call on a rotating basis, who, upon being notified of an emergency, wil notify the other appropriate San Antonio Water System divisions or departments based on the nature of the spil and the utilties affected. Upon notification of an uncontrolled release or spil and depending on the specific conditions and areas impacted, the person on call directs the proper sections (Risk Management, Sewer Maintenance, Wastewater Quality Control, Stormwater, Aquifer Studies Division, Water Quality Control) to respond.

145 EMERGENCY OPERATIONS PLAN FOR PUBLIC SUPPLY WELLS

ISSUE:

To provide an Emergency Plan for the San Antonio Water System's (SAWS) Public Supply Wells.

BACKGROUN:

During the years 1949 to 1956 a record drought in Texas brought the water level of the Edwards Aquifer down to a historic low. Some of the water wells experienced a measured increase in the amount of total dissolved solids as the "Bad Water" Line encroached furter to the north. At that time, the City Water Board was unprepared to deal with such an emergency. The San Antonio Water System must not be caught in the same predicament. The San Antonio Water System needs to anticipate potential emergency situations and be equipped to handle them. The transport and bulk storage of chemicals withi the San Antonio region offers a potential for contaminating a public water supply well(s). The City of San Antonio has been fortnate that an incident such as the one in the 50's has not occurred withi city limits.

POLICY ANALYSIS:

As San Antonio strives to prevent the degradation of water in the Aquifer by regulating the activities on the surface, it must also protect the water that is in the process of being distributed to customers. The San Antonio Water System has eighty-nine water wells which are spaced relatively close together. This close proximity places all of the wells at a risk to contamination. If one well becomes containated, there is a possibilty that a well close by wil become contaminated. During a crisis, to be able to provide the level of quality and service that citizens are accustomed to, SAWS must have an Emergency Plan for Supply Wells and be prepared to carr it out should circumstances arise.

The rapidly growing population and the increasing use of the Edwards Aquifer, necessitates the need for a plan of action in the event that a Public Supply Well becomes contaminated.

146 EMERGENCY OPERATIONS PLAN FOR PUBLIC SUPPLY WELLS

RECOMMNDATION:

In the event that the San Antonio Water System must implement an Emergency Spil Plan for Public Supply Wells, the San Antonio Water System shall:

a. notify all customers of the status of the emergency; b. imediately shut down water supplies; c. deduce the nature and origin of contamination; d. devise a plan of action to treat the water; e. provide customers with water through the use of SAWS water trucks or designated water pick-up sites; f. begin recirculation of water program.

* The cost and feasibilty of a Water Treatment Plant should be reviewed as a future means of water purification.

147 III

POTENTIAL ACTMTIES FUTURE STUDY BLASTING ORDINANCE

ISSUE:

The regulating agencies have always questioned whether blasting on the Edwards Recharge Zone has caused undetected damage to underground structures. The main concern is the effect on structures which might be sources or avenues for contamination to the Edwards Aquifer s~ch as sewer lines, underground storage tanks, and water wells.

BACKGROUN:

Currently, the State's Edwards Rules, Chapter 313, require blasting for a sewer line be done in accordance with the National Fire Protection Association. The City of San Antonio makes no special conditions for blasting over the Edwards Recharge Zone. The Edwards Underground Water District funded a study on the effects of blasting on engineered structures. The study results have shown that with the use of responsible blasting technques by the contractor, damage to engineered structures can be avoided. However, there is no mechanism in place to verify that these technques are being used.

POLICY ANALYSIS:

The study performed by the Edwards Underground Water District achieved two objectives. The first, was to determine how blasting degrades the integrity of underground structures and secondly, what criteria might be effective to limit facilty degradation. The study concentrated on the affects of blasting adjacent ~o various structures constructed according to city and state specifications. Some structures tested consisted of a sewer line, an underground storage tank and a water well. This report has established some potential relationships between the blast size, the conditions of the blast, and distance to the structure, which may aid in establishing guidelines for blasting on the Recharge Zone.

The report also indicated that there were good correlations between blast strengths, the blast wave, and depth which could be used for developing prediction technques for vibration control during blasting and would reduce risk to damaging structures which might cause contamination to the aquifer.

RECOMMNDATION:

Provide for mandatory reporting of blasting conditions prior to blast and a record of the blast which could be used to verify responsible blasting. Information to be provided to the San Antonio Water System are the following:

1. Date of blast 2. Location Description

1S0 BLASTING ORDINANCE

3. Blaster's Nanie 4. Contractor 5. Purpose of Blasting 6. Number of shots 7. Depth and Diameter 8. Type of Explosive 9. Amount of Explosive 10. Directional or not 11. Utilty map with distances to shot points 12. Utilties contacted 13. Fire Department contacted 14. Type of monitoring device 15. Include copy of monitoring device printout 16. Significant recharge features in the area including map with distances 17. Any comments or special conditions

In addition, the San Antonio Water System staff shall work with the San Antonio Fire Department to set up guidelines for blasting on the Edwards Recharge Zone.

151 DETERMINATION OF PRE-DEVELOPMENT CONDITIONS OVER THE EDWARS AQUIFR RECHARGE ZONE

ISSUE:

Data used to aid in determining the impact of development on the quality and quantity of water entering the interstream areas of the Edwards Aquifer Recharge Zone within Bexar County must be obtained. However, an undeveloped area must be monitored to determine conditions prior to changes in land use. The "Governent Canyon" area can provide such baseline conditions.

BACKGROUN:

The "1987 The Edwards Aquifer: Perspectives For Local and Regional Action". recommended that the City of San Antonio and the Edwards Underground Water District (EUWD) utilize respective experience and knowledge obtained from the Water Pollution Abatement Plan review and water quality monitoring to make adjustments and corrections to the regulatory process and to assure the prevention of the cumulative effect of pollution. This statement implies that a basic understanding of the pre-development conditions is needed. However, these pre-development conditions are not fully known because of a lack of available data by both the City and the EUWD.

In 1993, the San Antonio Water System in conjunction with the Edwards Underground Water District and the Texas Departent of Parks and Wildlife, purchased a tract of land known as "Governent Canyon". Much of this 4800 acre tract is located over the Edwards Aquifer Recharge Zone and is virally untouched by development. These conditions afford an extremely rare opportnity for scientific study. The data which would be obtained from such studies would be instrumental in the analysis of the potential impact caused by development on the Recharge Zone.

POLICY ANALYSIS:

A comprehensive study must be initiated in order to provide the appropriate agencies with data necessary to analyze the effects of development on water quality with the Edwards Aquifer Recharge Zone. Ths effort should include, but not be limited to, water quality and quantity, pollutant loading, and recharge potential of the watersheds being studied.

RECOMMNDATION:

The City Council Committee of the Whole on Water Quality realizes the necessity of obtaining ths valuable information and recommends the following:

~ That the appropriate actions be taken to determine a scope of work, obtain funding and secure a Consultat to proceed with a comprehensive study of the "Governent Canyon" area.

152 SEPTIC TANK MONITORING PROGRA

ISSUE:

Monitoring of septic tanks is proposed for septic systems in the Edwards Aquifer Recharge Zone.

BACKGROUND:

The City of San Antonio Council Committee on the Edwards Aquifer recommended in their October 1, 1987 report "The Edwards Aquifer: Perspectives for Local and Regional Action". section: Septic Tanks Summary Statements," a Septic Tank Monitoring program be implemented by the Edwards District.

POLICY ANALYSIS:

At this time, there is not a policy in place to address the Septic Tank Monitoring Program. A monitoring program to comply with the Council Committee recommendations is needed. Establishing a Septic Tank Monitoring program for testing ensures identification of contaminates exfiltrating from septic tank systems. The program wil include field inspection of all known septic systems existing over the Edwards Recharge Zone. Mapping then identifies concentrated areas of septic systems. These areas can then be studied further to locate migration of wastes to the Edwards. Observation wells wil be dug to determine the extent, if any, of migrating contaminants. This program involves a two phased approach. The first phase would be performed by the San Antonio Water System staff. They would research records, field verify each system and map the locations of these systems. This effort would require extensive coordination with Bexar County staff. A second phase would continue with enhanced studies of the highly dense areas of septic systems with the help of outside consultants to examine the effects of m1grating septic field wastes to the aquifer.

The advantage to ths program is the added protection afforded to the City's water supply. Significant additional costs are incurred in the second phase for the proposed engineering studies.

RECOMMNDATION:

It is recommended that City Council direct the San Antonio Water System staff to proceed with establishig the proposed Septic Tank Monitoring Program. The first phase wil be accomplished by Stormwater personnel without additional staff. The second phase would be proposed to Council after the extent of the "scope of study" is known. It would be reasonable to seek participation from Bexar County to complete the second phase of this study.

RECOMMNDATION:

Smoke testing confirs the integrity of the Sanitary Sewer System and tests private service lateral connections. It is recommended that San Antonio Water System (SAWS) staff work closely with Texas Natural Resource Conservation Commission (TNRCC) to continue the five year smoke testing program.

POLICY IMPLEMENTATION:

SAWS has a program in place to test the sanitary sewer system in the Edwards Aquifer Recharge Zone (EAR). The current program is in compliance with existing rules. The Edwards Aquifer Techncal Guidance Document proposes smoke testing be increased to a three year rotation.

These changes recommended by TNRCC to 30 TAC Chapter 13 (Edwards Aquifer) Rules, wil require SA WS to adjust the testing time table from a five year rotating basis to a thee year basis; continuous testing wil be. needed to comply with the new policies. STAF: Increase scheduling for testing wil require two additional inpectors; one vehicle and additional operating equipment and materials. TIMTABLE:

- SAWS recommends that no change be made in the five year smoke testing schedule.

178 PRIATE SANITARY SEWER SERVICE LATERAS

RECOMMNDATION:

The permitting, inpection and certification program administered by the San Antonio Water System (SAWS) is effective in monitoring the installation of private service laterals in the Edwards Aquifer Recharge Zone (EARZ).

It is reconiended that the program be expanded to include the watersheds that drain to the EAR. This opportnity can only come by way of amending the Unified Development Code.

POLICY IMPLEMENTATION:

Currently SAWS has a program in place to permit, certify and inspect private sewer laterals in the EAR.

Subsequent to changes to the Unified Development Code, including approval by SAWS Board, and the City of San Antonio, authorizing extension of SAWS inspection authority to the City of San Antonio's Extraterritorial Jurisdiction (ETJ) is needed.

This opportnity may come by way of amending the Unified Development Code. This would inure proper permitting, inpection, and certification of sanitary sewers and avoid pollution entering the EAR. STAF: The increase in area (ETJ) wil require two additional inpectors; one vehicle and additional operating equipment and materials. Approximately 30 man hours per week wil be required for the expansion of ths program.

TIMTABLE:

Amending the Unified Development Code wil tae one year. The expanded program wil be ready to begin as the code is amended to allow such inpections.

STORMWATER COMPRENHENSIV WATERSHED MANAGEMENT APPROACH (inc. DEVELOPMENT STANARS REVISION)

RECOMMNDATION:

It is recommended that the City Council begin efforts toward establishing watershed management within San Antonio. San Antonio Water System (SAWS) and City staff would begin the necessary study to present to Council, a delineation of each watershed and watershed targets.

Part of the efforts of watershed management wil encompass the establishment of criteria for addressing storm water quality emanating form new or redevelopment.

POLICY IMPLEMENTATION:

Ultimately this process would provide the input for any changes to current city ordinnces and the Unified Development Code to control storm water quality. .

1. A Watershed Management Committee comprised of City and SAWS staff to include affected parties wil conveiie to begin analysis of quantity and quality assessments.

2.. The Committee would intialize the process by dividing the City and Extraterritorial Jurisdiction (ETJ) into manageable watersheds. Targets of water quality would be established for each watershed by the committee.

TIMTABLE:

Six months to revise Chapter 34. Inspection program to be ongoing.

188 EXTEND JUISDICTION INTO EXTRATERRTORIAL JUSDICTION

RECOMMNDATION:

Extend the City of San Antonio's authority into the extraterritorial jurisdiction to protect the Edwards Aquifer water quality through adoption of Texas Water Code An. 26.177 and Texas Local Governent Code An. 401.002.

POLICY IMPLEMENTATION:

Policy can be implemented by adoption into Chapter 34 of the City Code and would require the following review and approval process to be required:

Even if the City Council adopts ths as an ordinnce, it must stil be approved by the Texas Natural Resource Conservation Commission (TNRCC) before the plan can be implemented. Timetable for ths is uncertin. According to the Water Policy Deparent of TNRCC, TNRCC is collecting data though 1996 to establish criteria to develop the rules on implementation procedures for ths program. The City of San Antonio might be able to receive approval on an implementation plan in 1996 after TNRCC establishes the rules for ths program.

189 EXTEND JUSDICTION INTO EXTRATERRITORI JUSDICTION

STAF:

The San Antonio Water System would require the addition of one Planner in position to review water quality protection measures for the extraterritorial jurisdiction.

COST:

The salary of the PÌanner in would be an additional $29,000. A fee for reviewing the proposed development could be used to make up for this additional cost. TIMTABLE:

If, City Council Committee of the Whole directs staff to implement this change through City Council adoption of the Committee recommendations, then it wil require approximately 6 months for the formal review and approvals of the various Committee's Commission's, and City Council as outlined above. However, it is uncertin whether TNRCC wil allow implementation of ths program before 1996. Review of the program by TNRCC may tae from 6 months to a year.

197 TECHNICAL IMPROVEMENTS EDUCATION AN INFORMATION

ISSUE:

Provide education and information to the public to encourage continued protection of our sole source of water the Edwards Aquifer.

POLICY IMPLEMENTATION:

Currently the thee regulatory agencies for the Edwards Aquifer are involved in the education process. The San Antonio Water SYStem (SAWS) has two educational programs in place; the Clean Stream program and the Major Rivers program.

Education and awareness of the Edwards Aquifer Recharge Zone should be encouraged among the Homeowners Associations, Commercial Developers, and the general public located on or traveling over the Edwards Aquifer Recharge Zone though the annual Texas Natural Resource Conservation Commission hearing.

In addition, the Texas Natural Resource Conservation Commission has begun to require the posting of signs at the entrances to new subdivisions inorming residents and visitors that they are on the Edwards Recharge Zone.

The Clean Stream program provides information on the abilty of some containants to fiter though the soil and into the Edwards Aquifer, containting our dring water. The program also describes how customers can contribute to the preservation and restoration of our streams and water systems. Information on recycling household hazardous waste such as used oil or standard bathroom cleaners and lawn care chemicals is provided along with tips and guidelines for their safe usage.

The San Antonio Water System maintain a continuing commitment to educating its customers. One of the most effective ways of undertg that education process is by making a long term investment in San Antonio's young people. Accordingly, the San Antonio Water System sponsors the Major Rivers Program in every fourt grade class in Bexar County. Major Rivers is a comprehensive water education curriculum originally developed by the Texas Education Agency and the Lower Colorado River Authority. It addresses the fuctions of Texas river basins and teaches young students about where water comes from, how precious it is, and how they can use it wisely. Major Rivers has been particularly successful and is very popular among elementary school educators.

POTENTIAL ACTIVITIES

. FUTURE STUDY BLASTING ORDINANCE

RECOMMNDATION:

Submit information on blasting conditions on the Edwards Recharge Zone to the San Antonio Water System prior to the issuance of a blasting permit from the San Antonio Fire Departent.

POLICY IMPLEMENTATION:

The San Antonio Fire Departent and the San Antonio Water System have begun a review of the San Antonio Fire Code to determine if ths can be implemented though the current language in the San Antonio Fire Code, Aricle 77. It has been determined that the recommended reporting requirements can be implemented imediately and the San Antonio Fire Marshall wil not issue a blasting permit unless an approval letter is issued by the San Antonio Water System. STAF:

This change alone wil not require an additional staff member, but wil increase the work load of the San Antonio Water System staff by approximately 3 hours weekly.

COST:

Approximately $1000 for trainig costs in blasting procedures and technques. TIMTABLE:

Current language in the Fire Code, Aricle 77 allows for imediate implementation with criteria spelled out for adminstrative procedures. Such procedures can be prepared with a 3-6 month time frame.

212 DETERMINATION OF PRE-DEVELOPMENT OF GOVERNNT CANON OVER THE EDWARS AQUIR RECHARGE ZONE

RECOMMNDATION: The City Council Committee on Water Quality realizes the necessity of obtaining information relating to pre-development areas and recommends the following:

~ That the appropritate actions be taken to determine a scope of work, obtain funding and secure a consultant to proceed with a comprehensive study of the Governent Canyon watershed area.

POLICY IMPLEMENTATION:

The San Antonio Water System and City of San Antonio wil enter into a contractual agreement with a private consultant agreeing to perform the following:.

1. Presentation to City Council on feasibilty (6 months);

2. Development of a scope of work (2 months);

213 SEPTIC TANK MONITORING PROGRA

RECOMMNDATION:

It is recommended that City Council direct the San Antonio Water System (SAWS) staff to proceed with establishing the proposed Septic Tank Monitoring Program. The first phase wil be accomplished by Stormwater personnel without additional staff. The second phase would be proposed to Council after the extent of the "scope of study" is known. It would be reasonable to seek participation from Bexar County to complete the second phase of this study.

POLICY IMPLEMENTATION:

This issue is proposed for two phases: The first phase would involve SAWS staff and Bexar County personnel assistance. This phase would involve researching and field inspecting known septic systems and mapping those that are currently in use. This phase would take approximately 1 year. During this time, discussions with the county would begin to enlist their participation for the detailed studies of phase two.

The second phase would be proposed to City Council in a report and recommendation on further study needs. The concept for ths approach is to study only the dense areas of septic

system users. The second phase studies would be carried out by outside consultants. These more detailed studies would involve soil sampling and testing and ground water sampling and testing. The results would identify areas where the ground water is being affected by septic tank fields. STAF:

It is estimated that twenty hours weekly of all combined staff from the Stormwater Departent wil be dedicated to this project. TIMTABLE:

The results of phase. one wil be complete with one year and ready to present to Council for approval to enter the second phase.

In 1967, the Texas Water Quality Act created the Texas Water Quality Board and gave it

a mandate to protect the quality of the state's waters. In 1970, TWQB issued its first "Board Order" regulating development over the recharge zone of the Edwards Aquifer. The goal was to prevent contamination of the aquifer by pollutants introduced by surface runoff. This was a unique regulation, which had no parallel in any other aquifer in Texas. The Board amended and strengthened this order in 1974.

Meanwhile, the proposed development of "San Antonio Ranch", a federally supported "new town" over the recharge zone in northwest Bexar County, raised public concerns over possible pollution of the aquifer. The Sierra Club and other citizens' groups filed suit to block the federal loan guarantee for the project, but the appeals court upheld HUD' s action in granting this assistance to the developers. i In response to the concern raised in the case, San Antonio Congressman Henr B. Gonzalez introduced an amendment to the Safe Drinking Water Act which provided special protection to an aquifer which is a "sole source" of water in an area. 2 The Edwards was the first aquifer in the to be so designated under this provision.

In October 1975, the San Antonio City Council approved rezonig of a 117 acre site at the intersection of U.S. 281 and Loop 1604 for a regional shopping mall. At the same time, it created an Edwards Recharge Overlay Zone in the city's zonig ordinance and established an Aquifer Protection Office in the city Public Works Departent to review developments proposed over the recharge zone. The controversy over the rezonig, however, resulted in a petition drive to force a referendum on the issue, as authorized by the city charter. By January 1976, the Aquifer Protection Association had secured enough petition signatures to call the referendum. The rezonig ordinance was rejected by the voters overwhelmingly. The developers fied suit, and the Texas 'Supreme Court eventually ruled that zonig changes could not be made the subject of a referendum. 3

Meanwhile, in the wake of the referendum, in May 1976 City Council commissioned a major study by consultants Metcalf & Eddy to determine whether the mall rezonig endangered the aquifer. In November, the study was expanded to consider broader questions of how much development could safely be allowed over the recharge zone. In June 1977, the City Council enacted a moratorium banng all development over the recharge zone, pending the outcome of ths study. Suburban developers imediately fied suit, seekig massive damages for an unconstitutional tag of their propert without compensation. In September, the Council adopted an Interim Development Ordinance which recognied vested rights for previously approved projects and allowed some limited development over the recharge zone, and the lawsuit was dropped.

3 San Pedro North, Ltd., vs. City of San Antonio. 562 S.W. 2d 260 (Tex. Civ. App.-- San Antonio 1978, writ ref'd n.r.e.). 234 The final report of the Metcalf. & Eddy study, in 1979, was generally regarded as inconclusive. It recommended further work to identify the most sensitive areas and features of aquifer recharge. City Council repealed the Interim Development Ordinance and development over the recharge zone resumed. Regional Water Resource Study

In 1982, continuing concerns over the lack of a long range water plan prompted the City Plannng Commission to form an ad hoc committee to study the issue. This committee's report recommended a detailed study of long range water resources in the entire Edwards Aquifer region, guided by a carefully structured Techncal Advisory Committee. In November 1983, the City and Edwards Underground Water District agreed to sponsor this study jointly. They created a Techncal Advisory Committee to define the scope of work and recommend a consulting fir to undertke the study. The firm of CH2M-Hil was selected, and subsequently submitted its thee volume report in April 1986.

In June 1986, the Council and the Edwards District formed a Citizens Advisory Group to help in reaching a consensus on the study's recommendations. In January 1987, the City and the Edwards Board created a Joint Sponsors Committee to recommend legislation which both bodies could support in the 1987 legislative session. In March, the Joint Committee recommended a policy that the aquifer "should not be overdrafted during periods of average rainall" -- that is, that long term average withdrawals from the aquifer should not be allowed to exceed the aquifer's long term average annual recharge. It also recommended that the Edwards District's enabling Act should be amended to require the District to develop and implement a Drought Management Plan.

The legislation mandating a Drought Management Plan was passed in 1987 as HB 1942. The same Act increased Bexar County's representation on the Edwards District's Board to six members, thus providing equal representation to the three major constituencies interested in the aquifer. It also authorized 10% of the voters in any county within the District to petition for a referendum to withdraw from the District. City Council Commttee on the Aquifer

In April 1987, another shopping mall zonig case over the recharge zone reignited the controversy of the 1970s over possible pollution of the aquifer. The San Antonio City Council approved the rezonig of a tract near the intersection of Loop 1604 and NW Miltary Highway. In response to the ensuing controversy, the Mayor appointed a Special Committee on the Aquifer to consider the full range of actions necessary to protect the aquifer.

The Committee met throughout the summer of 1987, hearing from a wide range of techncal experts and from a panel of "intervenors" on both sides of the issue. In September, it presented its report,4 which recommended a policy of "no degradation" in the quality of aquifer water. It proposed a wide range of implementing actions, addressed to thè City,

4 The Edwards Aquifer: Perspectives for Local and Regional Action. September 1987. 235. Bexar County, the Edwards District, and various state agencies. Among these was an amendment to the zoning ordinance providing that a zoning change over the recharge zone would not be considered until the Texas Water Commission had approved a Water Pollution Abatement Plan for the development. The Committee's report was adopted by the Council unaniously. Regional Water Resources Plan

Following the report of the Council Committee, the Joint Committee of City Council and the Edwards Board (now called the Joint Committee on Water Resources) reconvened to continue the development of a long range regional water plan. A representative of the downstream river authorities was added to the Committee to ensure that their interests were also considered.

In July 1988, the Joint Committee presented the San Antonio Regional Water Resources Plan. It contained four principal components, in addition to financing recommendations and an implementation program.

First, it recommended a series of conservation programs designed to reduce total regional water consumption by 10% within 10 years. This translated into a reduction of 16 % in municipal water consumption, while no specific goal was set for agricultural conservation.

Second, it recommended that the City of San Antonio underte an ambitious wastewater reuse program to substitute for 131,000 acre-feet of demand on the aquifer by 2040. This would be financed by the city's sewer ratepayers, although the benefits of the program would accrue to the region as a whole.

Third, it recommended a series of projects to develop surface water supplies. It recommended that the Applewhite project be built imediately, since it was the only project which was already permitted and it was already largely designed. It also recommended that work begin on the process to permit Cibolo reservoir (which had been authorized by Congress in 1974) and Cuero/Lindenau, both of which would be needed before the plan's horizon of 2040.

Finally, it recommended a program of groundwater allocation based on recognition

of historic pumping rights. This would iimit pumping from the aquifer to 450,000

acre-feet per year -- a figure that would 'leave at least 150,000 acre-feet of spring discharge for downstream use on the Guadalupe River under average rainfall conditions. Irrigators would be authorized to pump whatever amount was necessary to grow crops on their historically irigated acreage. New users would have a period of seven years to establish similar historic rights. The Edwards District would establish a market for the sale or lease of aquifer water rights. The Edwards District would establish a market for the sale. or lease of aquifer water rights in which agricultural pumping rights would be quantified at 1.5 acre-feet per irrigated' acre. It would also develop a program to purchase existing rights from wiling sellers in order to retire these rights to meet the 450,000 AF limit, and it would become the broker of bulk regional water supplies. 236 The San Antonio City Council adopted this plan in July 1988. The Edwards Board, including the representatives from Medina and Uvalde Counties, approved the concept of the plan but reserved the right to review the proposed implementing legislation.

Soon after the concept plan was approved, however, a movement began in Medina and Uvalde Counties to repudiate it. Petitions were circulated, and in January 1989 both counties voted overwhelmingly to withdraw from the Edwards District.

237 URAN DEVELOPMENT ON THE EDWARS AQUIFER RECHAGE ZONE A SUMMAY OF THE EUW STAF REPORT

The Edwards Underground Water District (EUW) issued a report in August 1993 in response to the growing concern by District staf that the current mechansms in place to protect the Edwards Aquifer from degradation due to urbaniation are not adequate. The report is not a technical report based on techncal data but a narative of the stafrs concerns, mainly targeting the issue of stormwater ru-off.

District staff states that the Edwards "Board Order" rules concernng the aquifer provide insufficient protection from contamation and that it is withi the power of the Texas Natural Resource Conservation Commssion (TNCC) to requie more stringent measures on water quality protection than are specicaly described in the Edwards Rules. In their report the EUWD staff brig to light varous approaches, in the form of general recommendations, to protecting ground water from contamnation, .

The report states that studies that have been conducted on the effects of urban development on water quality have proven that there is a direct relationship between stormwater pollution and impervous cover, but none of the data is represented. The report goes on to say that as development expands and the amount of impervous cover increases, the amount of infiltration of rainfall into the soil is reduced, causing an increase in stormwater run-off. The increase in the amount of impervous cover reduces recharge to the aquifer and the abilty of contamnated stormwater ru-off to be diluted through natural filtration and adsorption. Currently, no restrictions exist to lit the amount of impervous cover being constructed on the Recharge Zone.

One of the recurring concern through-out the report is the lack of a "cumulative effects" evaluation of the development activities on the Recharge Zone. Due to the rapid pace of development and the current lack of adequate comprehensive standards and regulatory controls, District staff believes that contamation of the aquifer is "iment."

256 COMMENTS BY CITY OF SAN ANTONIO ON CHAPTER 313 CITY OF SAN ANTONIO COMMENTS REGARDING EDWARS AQUIFER RULES 1- SECTION 313

TEXAS NATURAL RESOURCE CONSERVATION COMMISSION

The San Antonio Water System has reviewed the latest edition of the Edwards Chapter 313 rules. San Antonio has long supported water quaity as a primar issue. As reflected in the October, 1987 report The Edwards Aauifer: Perspective for Local and Regional Action. the San Antonio Water System has made great efforts in cooperation with the Texas Natual Resource Conservation Commission (TNRCC) and the Edwards Underground Water Distrct to define problems and solutions for Aquifer protection. These are primarly for mapping, hazdous materials, water pollution abatement plan (WP AP' S) and the drainage area. The following statements have been provided to the San Antonio Water System Board of Trutees and approved by resolution by the City of San Antonio City Council on March 17, 1994. On

behalf of the City of San Antonio City Council, the San Antonio Water System's concern are much in keeping with previous comments. The San Antonio Water System greatly appreciates the opportity on behalf of the San Antonio City Council to submit the following comments for review and consideration by the Texas Natual Resource Conservation Commission. .

RECOMMENDATIONS FOR CHAGES TO THE CHAPTER 313 RULES

The following are recommended changes from the San Antonio Water System to the TAC Chapter 313 rules.

313.4 WATER POLLUTION ABATEMENT PLANS

313.4 (b) (3)

That all residential developments, including single family residential of less than 25 lots, should bePlan. required to provide a geologic . assessment along with a complete Water Pollution Abatement 313.4 (4) (d) (2)

Plans submitted for protection of significant recharge featues discovered durng constrction should be required to be certified by a Texas Registered Professional Engineer.

258 3 13.4 (4) (g)

That Water Pollution Abatement Plans approved prior to 1989 and in which some construction was performed but the development was never completed, must modify their Water Pollution Abatement Plan that was submitted prior to 1989 to address the new requirements of the application.

313.5 ORGANIZED SEWAGE COLLECTION SYSTEMS

. 313.5 (C) (2) (i)

Sewer line PVC pipe required for gravity collection systems should be upgraded to City of San Antonio standards of SDR 26.

313.5 (C) (5)

Immediate emergency measures for detected defects should be implemented to prevent pollution as referenced in Chapter 26 of the Texas Water Code using such methods as deemed necessar to prevent contamination to the water quality of the Edwards Aquifer. Final repairs should be initiated withn 90 days of detection of strctual defects.

313.5 (C) (11)

Plans submitted for protection of significant recharge featues discovered durng trenching and construction of sewer lines should be required to be certified by a Texas Registered Professional Engineer.

313.8 PLUGGING OF ABANDONED WELLS

Plugging requirements should be strengtened (upgrade Chapter 287), for example:

Verification of borehole conditions should be provided by the rung of a wireline log. Ths log can provide information such as tota depth, casing point, casing condition, and formation tops. Ths information can aid in designig an appropriate plugging program.

I t should be required that the uncased portion of the drlled hole be filled with washed gravel from the bottom up to withn 3-5 feet of the bottom of the casing.

259 F or a length of approximately 8-10 feet on top of the gravel a plug should be put in place using pressure cementing or a non-shrink grout.

Once the plug has set-up, the water above the plug is pumped or bailed out to verify the seaL. (V ery Important)

Then the entire casing, from the top of the plug to the surface is to be pressure cemented or a non-shrink grout be. used.

313.9 PROHIBITED ACTIVITIES

313.9 (a) and (b)

All landfills should be prohibited from being placed on the Recharge Zone and Transition Zone which requires a permit from TNRCC.

313.10 STATIC HYDROCARBON AND HAZARDOUS SUBSTANCE STORAGE

313.10 (1)

The addition of tertiar containment for Underground Storage Tans on the Recharge Zone as well as the Transition Zone should be required.

313.10 (Addition)

That the submittal of an Emergency Spil Response Plan should be a condition of the approval of an underground storage ta facilty.

313.10 (Addition)

That a five year timetable be set up to require the upgrade of existing single wall tas and piping on the Recharge Zone and the Transition Zone to be upgraded to at leas double wall tas and double wall piping. If Tertiar requirements are to be extended to the Recharge Zone and the Trasition Zone, then the systems should be upgraded to ths leveL.

That sites containing underground storage tas be required to test ru-off prior to entering permanent stormwater abatement strctues and upon discharge from said abatement strctue. These analytical tests shall be for an approved list of potential containants and shall be performed by an EP A approved laboratory.

260 313.11 STATIC HYDROCARBON STORAGE IN ABOVEGROUND STORAGE TANKS

313.11 (Addition)

That the submittal of an Emergency Spil Response Plan should be a condition of the approval of an aboveground. storage tan- facilty.

313.14 ENFORCEMENT

That the TNRCC staff may be granted more authority to penalize violations in the field and enforcement be expedited for such violations.

Maintenance and upkeep responsibilties of stormwater abatement stctues need to be addressed.

That the manpower be increased for the Edwards Aquifer program in order to provide increased enforcement.

GENERAL COMMENTS

OVERALL POLICY

The City of San Antonio urges the Texas Natual Resource Conservation Commssion stf to begin to develop methodology and criteria for reguating and monitorig cumulative effects of land use activities over the Edwards Recharge Zone. These "cumulative effects" have been occurrng over time and the need to assess water quaity in term of pollutat loading mus be studied. Such studies should be coordinated with appropriate local entities for techncal assistance and provide necessa information.

The TNRCC should estblish formal communcations with the Texas Ralroad Commssion and the Texas Deparent of Transporttion on new constrction, repairs, accidenta spils rromoil and gas pipelines, and tranporttion of hadous materials.

BOUNDARIES

The San Antonio Water System requests the estblishment of a Drainage Zone, similar to the boundaries of the catchment area, to be phased in over the next 3 years with similar regulations that govern the Recharge Zone, especially, in the ar~as of underground storage ta, proper

261 construction and inspectìon of sewer mains and private service laterals, and stonnwater abatement controls.

That buffers be established along 100 year floodplains in the Recharge Zone and a newly established Drainage Zone.

Flòodplaìns would be defined as those desìgnated on the FEMA maps or on creekbeds with watersheds of greater than 300 acres.

INFRASTRUCTURE

That septic tas have a mandatory pumping requirement every 3 years. That new septic ta systems have a monitor well instaled for observatìon and testing puroses every thee years in conjunction with the mandatory pump out of the septic system.

Physical removal and fill operations withn the 100 year floodway should be prohibited unless the project involves the perpendicular crossing of roadway construction, is shown to improve drainage, enhance recharge, or protect water quaity.

The San Antonio Water System is recommending that the Texas Natual Resource Conservation Commission require detaled reporting of conditions surounding blasing on the Recharge Zone. Especially the proximity of a blast to the closest sewer lines, amount of explosive, and monitoring of the blas with a copy of the monitoring device printout. Other items for consideration are the following:

1. Date of blast 2. Location description 3. Blaser's Name 4. Contractor 5. Purose of Blasng 6. Number of shots 7. Depth and diameter 8. Type of explosive 9. Amount of explosive 10. Directiona or not 11. Utilty map with distces to shot points 12. Utilties Contacted 13. Fire Deparent Contacted 14. Type of monitoring-seismic or sound 15. Include copy of monitoring device printout i 6. Signficant recharge featues in the area including map with distances i 7. Any comments or special conditions

262 That Hazardous Material Traps be required in close proximity to sensitive recharge areas, and where highways cross stream chanels based on guidelines set in the "Edwards Aquifer Technical Guidance Manual".

Certification of commercial fertilzer and pesticide applicators operating within the Edwards Aquifer Recharge Zone.

FEE SCHEDULES

That the TNRCC, for the next legislative session, attempt to change the water code to charge larger fees for larger developments and a fee that is to be set on a per underground/aboveground storage ta basis with no maximum. However, to encourage Master Water Pollution Abatement Plans for large developments or a group of smaller developments willng to develop a single Master Water Pollution Abatement Plan, a credit system on the required fees should be implemented.

City of San Antonio agrees that the fee schedule needs redefining and ths redefining should emphasize that collected fees be placed directly back into the program.

EDUCATION

Education and awareness of the Edwards Aquifer Recharge Zone should be encouraged among the Homeowner Associations, Commercial Developers, and the general public located on or traveling over the Edwards Aquifer Recharge Zone.

TECHNICAL GUIDANCE MAUAL

In addition, the new "Edwards Aquifer New Techncal Guidance Document" should be used on a tral basis for a period of one year and evaluated for its effectiveness and amended where needed. If it is determned to be a benefit to regulating development on the Recharge Zone it should be considered for adoption into the Chapter 3 i 3 rues.

The City of San Antonio appreciates the opportty to comment on the Chapter 3 i 3 Edwards Aquifer Rules.

system. New sewer lines and manholes must be tested every five years thereafter in accordance with paragraph (5) of this subsection. (5 ) Testing of existing sewer lines. Owers of sewage .collection .sys-temsmust insut'e that all existing sewer lines having a diameter greater than or equal to six (6) inches, including private service laterals, manholes, and connections, are tested to determine types and locations of structural damage and defects such as offset or open joints, or cracked or crushed lines that would allow exfiltration to occur. Such testing shall commence within one year of the effective date of this chapter, or within one year of the effective date of any former chapter of this title (relating to Edwards Aquifer) (now repealed), and shall be completed within five (5) years of commencement. Every five (5) years thereafter, existing sewer collection systems must be tested to determine types and locations of structural damage and defects such as offset or open joints, or cracked or crushed lines that would allow exfiltration to occur. These test results shall be certified by a Texas Registered Professional Engineer. As soon as possible, but at least within one (1) year of detecting defects, measures to initiate repairs to the sewer collection system must be carried out by the system t s owner. Any necessary repairs must be certified by a Texas Registered Professional Engineer as having been correctly performed. Necessary repairs must be tested within 45 days of completion of the repairs, and the results of such testing must be certified by a Texas Registered Professional Engineer. Both certifications must be submitted to the appropriate district office within 30 days of testing the completed repairs. (6 ) Blasting for sewer line excavation.

The location of such "stub outs" must be marked ontne ground such that the location of such "stub outs" can be easily determined at the time of connection of the extensions. Such "stub outs" must be manufactured wyes or tees that are compatible in size and material with both the sewer line and the extension. At the time of original construction, new "stub-outs" must be constructed sufficiently to extend beyond the edge ( s ) of any street pavement under which they must pass to the property line. All "stub-outs. must be sealed with a manufactured cap to prevent leakage. Extensions that were not anticipated at the time of original construction or that are to be connected to an existing sewer line not furnished with "stub outs. must be connected using a manufactured saddle and in accordance with accepted pluming techniques. (8 ) Locating sewer lines within a five (5) year floodplain. Sewer lines shall not be located within the five (5) year floodplain of a drainageway. In an area where the executive director determines that such location is unavoidable, and the area is subject to inundation and stream velocities which could cause erosion and scouring of backfill, the trench must be capped with concrete to prevent scouring of backfill, or the sewer lines must be concrete encased. All concrete shall have a minimum thickness of six (6) inches. (9 ) Inspection of private service lateral connections. After installation of, prior to covering, and prior to connecting a private service lateral to an organized sewage collection system, the owner of the private service lateral line shall provide that a Texas registered professional engineer, Texas registered sanitarian, or appropriate city inspector must visually inspect the private service lateral and the connection to the collection system, and certify it to have been constructed in conformity with the applicable provisions of this section.
