0 Input for making land use decisions (i. e,, designing long term active and passive institutional controls for the site).

Groundwater exists both above and below the WIPP repository, but no hydrologic continuity exists between the repository and the groundwater. Groundwater below the repository occurring in the sandstones of the Delaware Mountain Group (Powers, et al., 1978) is isolated by bedded salt deposits in the lower part of the Salado Formation and in the underlying Castile Formation. Groundwater below the repository is not being monitored as part of this program.

Groundwater above the repository is being monitored. Groundwater exists in both the Dewey Lake Formation and the Rustler Formation. Zones monitored for background characterization within the Rustler are the Culebra and the Magenta members. These zones appear to be dolomite units isolated from one another by impermeable units. With the exception of excavated shafts at WIPP, these zones are isolated from the repository excavations by bedded salt deposits in the upper two thirds of the Salado Formation.

Postbackground surveillance is focused on the Culebra because it is the primary flow path within the Rustler formation. Databases are maintained for the Magenta so that if the need arises surveillance of the Magenta can be resumed.

The Culebra is areally persistent, but quantity and quality of water va; y considerably from place to place. The dolomite is vuggy, fractured, and commonly associated with anhydride (Lambert and Mercer, 1977). The Culebra has a low hydraulic conductivity. It is a fractured unit that is best modeled as a dual porosity media. Water yields are small and saline (Powers et al., 1978).

The Magenta is finely crystalline and dense. Like the Culebra, the Magenta has a low hydraulic conductivity through fractures and contains limited amounts of poor quality water (Powers et al., 1978).

The Dewey Lake Redbeds consist of orange red silt stone, mud stone, and some 11 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN sandstone. The Dewey Lake Redbeds do not form an aquifer, but some permeable sand lenses are present and those yield limited quantities of fresh water to a few private wells in the area around the WIPP site (Powers et al., 1978). One such sand lens has been identified within the WlPP boundary and is scheduled for surveillance as part of the WQSP.

5.2 Surveillance Well Construction Many of the WIPP surveillance wells were drilled and completed prior to 1980. As the WIPP Project progressed, additional monitoring wells were completed in the vicinity of the site. Drilling of the bulk of WlPP surveillance wells began in 1976 and continued into 1988.

In general, all of these wells were drilled as part of the geologic site characterization and resource evaluation programs. Most WlPP surveillance wells were drilled and completed using oil field techniques. Surveillance wells at the site have been completed, generally, using two types of installations. One installation requires drilling the well to some depth below the base of the Culebra and then casing the well to the bottom of the hole. The interval of the Culebra or Magenta is then perforated to allow access to the formation for testing or sampling purposes. The second type of installation consists of drilling the hole to a depth just above the top of the Culebra, installing well casing to the bottom of the drilled hole, and coring or drilling through the Culebra interval, leaving the Culebra interval open to the formation.

These types of well completions presented problems in collecting undisturbed and representative samples from the water bearing units. The open hole completions have, in some cases, resulted in sediments below the CuIebra being exposed in the sampling interval. In some cases, these sediments are rich in halite or other evaporite minerals, causing the water chemistry in the well bore and the water bearing unit surrounding the well to be altered. Often, during drilling and completion of surveillance wells, fluids containing fresh water, saturated brine, and drilling fluids containing petroleum products have been introduced into the well bore. In some cases, these fluids were left standing in the well bore for extended periods of time, resulting in contamination of the surrounding formation (Crawley 1988).

Standard oil field steel well casings have been used during completion of the WlPP surveillance wells. This type of casing is easily corroded by the brackish to brine water found in the WlPP area. Based on serial sampling results, it appears that the products of well casing corrosion migrate from the well bore into the formation, resulting in a halo or plume of groundwater with altered chemistry surrounding the surveillance wells. Obtaining a representative sample has required that the surveillance wells be pumped for long periods of time to remove the contamination.

Well drilling and completion techniques such as those described above are usually not used for installation of monitoring wells employed in RCRA or sther groundwater 12 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN sampling programs, due to the likelihood of aquifer contamination. These practices required that the WQSP use extensive groundwater pumping in order to obtain uncontaminated water samples.

The difficulty in obtaining representative groundwater samples, due to the design of the wells used by the WQSP, necessitated the use of a serial sampling technique. Serial sampling and the associated equipment are discussed later in this section.

Seven observation wells were completed after the baseline was established using EPA recommended drilling methods and casing materials that have the potentiar to meet RCRA monitoring standards. Six of the wells were completed in the Culebra; one well in the Dewey Lake formation. Two years of sampling are scheduled prior to the anticipated receipt of waste. The data gathered from these wells will be compared to the existing database and the existing background data will be appended as appropriate.

The configuration of the seven new observation wells may well preclude the necessity to perform serial sampling. However, sampling of a portion of the older surveillance wells may be necessary in years to come. Therefore, a discussion of serial sampling techniques is included in this document.

5.3 Samdina Proaram Descrbtion The WQSP has employed two types of sampling procedures at the WIPP: serial sampling and final sampling.

5.3.1 Serial Sampling Serial sampling is the collection of sequential samples for the purpose of determining when the water chemistry stabilizes or reaches a steady state. Ideally, when the water chemistry stabilizes, it is assumed that the chemistry is representative of the native formation fluid, and a final sample is collected. However, in reality, serial sampling leads to the collection of water samples with reproducible chemistries which may or may not be representative of the undisturbed groundwater. The water samples may still be impacted by well construction practices and effects from the installation of downhole pumping and sampling equipment.

During the background characterization phase of the WQSP serial sample, field parameters were monitored on a daily basis. After completion of the background characterization phase, monitoring of serial sample parameters was modified by pumping each well for 48 hours prior to the start of serial sampling then comparing the serial sampling analysis results to the average last day serial sample results for previous sampling rounds. A 95 percent confidence interval was established for com pa riso n standards.

13 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN The field analytical parameters found to be the most useful in identifying a steady state condition of the water chemistry include chloride, divalent cations (hardness), and alkalinity, which are analyzed by classic wet chemistry bench methods (titration). Totai iron has also been found to be a useful indicator and is analyzed using spectrophotometric methods. Other serial sampling parameters analyzed in the field include measurement of pH, Eh, temperature, specific conductance, and specific gravity. Procedures for collection and analysis of serial samples are processed, approved, and maintained by the site documentation process.

5.3.2 Final Samples Final groundwater samples are collected once evidence from serial sampling indicates that the pumped groundwater has reached a chemical steady state. Final samples are forwarded to a contract analytical laboratory for analysis.

Final samples are collected in the appropriate type of container for the specific analysis to be performed, For each parameter analyzed, a sufficient volume of sample is collected to satisfy the volume requirements of the analytical laboratory. This includes an additional volume of sample water necessary for maintaining quality control standards. All final samples are treated, handled, and preserved as required for the specific type of analysis to be performed. Details about sample collection, preservation, and volumes required for individual types of analyses are found in the applicable procedures generated, approved, and maintained by the site documentation process.

Splits of the final sample are provided to oversight agencies and WIPP stakeholders as requested by the DOE. A split of the sample is also placed in storage within the ES& H Environmental Sample storage area and held until final reports from the contract analytical laboratory have been evaluated and approved. When the final laboratory report has been approved the samples are removed from storage and destroyed.

Detailed protocols, in the form of procedures, assure that samples are collected in a consistent and repeatable fashion. Procedures applicabie to water quality sampling are generated, approved, and maintained by the site documentation process.

The serial sampling process will probably not be needed with the wells completed specifically for water quality sampling. However, during the first two years of sampling, the wells will be serially sampled using an abbreviated method. It is anticipated that changes in the water chemistry from stagnated to representative will occur within the first 24 hours of the purging process. Whereas, this change usually occurred over a seven day period with the old wells.

During the first two or three years of sampling, these wells will be serially sampled with the first sample being analyzed as soon as possible after the pump is turned on and daily there after for a period of four days or until the field parameters (chloride, divalent 14 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN cations, alkalinity and iron) stabilize. Eh, pH, and conductance will be monitored continuously by using a flow cell with ion specific electrodes and a real time readout. After two years of sampling data have been accumulated, a decision will be made to determine if the serial sampling process can be eliminated. If serial sampling is removed from the water quality sampling well protocol, the decision to collect samples will be based on the number of well bore volumes purged and the results of continuous monitoring of temperature Eh, pH, and conductance.

5.4 Groundwater PumDina and SarnDlina Svstems The water bearing units at the WlPP are highly variable in their ability to yield water to surveillance wells. The Culebra, the most transmissive hydrologic unit in the WlPP area, exhibits transmissivities that range many orders of magnitude across the site area and has been the primary focus of the GSP. The Magenta has a lower transmissivity and yields very small quantities of water to wells. Because the water yielding characteristics of the hydrologic units at the WlPP are variable, different types of pumping equipment are used during water quality sampling activities.

The groundwater pumping and sampling systems used to collect a groundwater sample are designed to provide continuous and adequate production of water so that a representative groundwater sample can be obtained. The wells used for water quality sampling vary in yield, depth, and pumping lift. These factors affect the duration of pumping as well as the equipment required at each well. Based upon expected yields, the wells monitored at WlPP can be divided into three categories according to flow rate: (1 ) high flow rate of 10 to 25 gallons per minute (gpm); (2) medium flow rate or 1 to 10 gpm; and (3) low flow rate of less than 1 gpm.

The high and medium flow rate wells may use a submersible pump packer assembly. The low volume wells may require a gas driven piston pump packer assembly. A discussion of the different pump packer equipment is provided below.

The type of pumping and sampling system to be used in a wet1 depends primarily on the aquifer characteristics and well construction. For example, if well construction is such that it yields contamination to the aquifer (i. e., metal casing) a packer is normally recommended to minimize purging time, If the aquifer yields adequate water to the well to be classified a high or medium production well, a submersible electric pump may be used. However, if the well is completed with the water bearing unit uncased, a gas piston pump may be needed to minimize stress to the formation walls to prevent collapse of the formation.

Wells that are completed to water quality standards are cased and screened through the production interval with materials that do not yield contamination to the aquifer or allow the production interval to collapse under stress. An electric, submersible pump installation without the use of a packer is an acceptable installation in this instance. WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN The largest amount of discharge from the submersible pump takes place from a discharge pipe. In addition to this main discharge pipe a dedicated nylon sample line, running parallel to the discharge pipe, is also used. Flow through the pipe is regulated on the surface by a flow control valve andlor variable speed drive controller. Cumulative flow is measured using a totalizing flow meter. Flow from the discharge pipe is routed to a discharge tank for disposal.

The dedicated nylon sampling line is used to collect the water sample that will undergo analysis. By using a dedicated nylon sample line, the water is not contaminated by the metal discharge pipe. The sample line branches from the main discharge pipe a few inches above the pump. Flow from the sample line is routed into the sample collection area. Flow through the sample collection line is regulated by a flow control valve. The sample line is insulated at the surface to minimize temperature fluctuations.

A gas driven pump and sampling system can be used on any volume well. When used, the pump intake is set at a predetermined depth near or in the production zone. The pumping rate is adjusted to maintain the water level in the well above the pump intake.

The flow rate for gas driven pumps is controlled by regulating the air pressure on the pump intake or by a flow control valve. Water is continuously discharged into a water storage tank. Detailed protocol for assembling, installing, and controlling pumping and sampling systems is found in the procedures generated, approved, and maintained by the site documentation process 5.5 Pressure Monitorina Svstems Regardless of which pump is used when sampling a well that was drilled for the geologic site characterization and resource evaluation program, a packer is used to isolate the pump intake from contaminated well bore fluid that exists in the well above the sampling zone. If the packer seal is not good, contaminated water from above the packer can leak into the formation water being sampled and bias analytical results. If the packer has a good seal the pressure above the inflated packer should remain con st ant.

Pressure above the packer is monitored using transducers and/ or bubblers to verify that the seal on the packer is good. Pressure below the packer is monitored to ensure that water levels do not fall below the pump intake. Periodic checks of the pressures are conducted during field sampling to verify packer seal integrity. These field checks are recorded on Field Activity Log Forms.

Wells drilled to water quality specifications do not require the installation of a packer because sample biases due to well construction deficiencies are not present. However, pressures will be monitored in the formation to maintain water level above the pump intake. Procedures governing the installation and use of pressure monitoring devices are generated, approved, and maintained by the site documentation process.

16 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN 5.6 Sample Analvsis The mobile field laboratory provides a work place for conducting field sampling and analyses. The laboratory is positioned near the wellhead, is climate controlled, and contains the necessary equipment, reagents, glassware, and deionized water for conducting the various analyses.

Two types of water samples are collected: serial samples and final samples. Serial samples are taken at regular intervals and analyzed in the mobile laboratory for various physical and chemical parameters (called field parameters). The serial sample data are used to determine the chemical steady state conditions of the groundwater, as a direct function of the volume of the water being pumped from the well. Interpretation of the serial sampling data enables the TL to make a determination of when steady state conditions are attained in the pumped groundwater.

Final samples are collected when the serially sampled field parameters have achieved a steady state. If one or more of the field parameters do not stabilize, and there is reason to believe it will not, the TL may choose to collect the final sample regardless of this instability in the field parameter( s).

The objective of the serial sampling effort is to obtain representative water samples in a reproducible manner. By definition, a representative groundwater sample is a sample of undisturbed groundwater. A groundwater sample is considered to be representative of the undisturbed groundwater only if it is chemically identical to the undisturbed groundwater (i, e., completely unaltered by the effects of drilling, postdrilling processes and reactions, and sampling procedures). Obtaining a representative groundwater sample is a theoretical ideal. For example, the redox potential of the aquifer groundwater, Eh, is likely to change as a result of pressure decreases (gas loss) and contamination by atmospheric oxygen that occurs during the sampling process. The ratios between the different oxidation states of a multivariant element may change, and the total concentration of that element may also change during sampling due to precipitation.

To determine how close the pumped groundwater is to being representative, a comparison is made by monitoring the same selected field parameters whiz5 were used to initially define the background characteristics of the water. When these parameters appear stable, then the determination is made that the water sample is representative. Stability is usually defined as * 5 percent of the average of preceding parameter measurements made on the final day of sampling for previous rounds.

When stability has been determined, a final sample is collected. The final sample is considered to be as representative a sample of the undisturbed groundwater as can possibly be obtained considering the analytical and technical means at hand.

17 WP 02 1 Rev. 3 G RO U N DWATER SU RVEl LLAN CE PROGRAM PLAN 5.6.1 Serial Samples Serial samples are collected and analyzed in the mobile laboratory to detect and monitor the chemical variation of the groundwater as a function of the volume of water pumped. The purpose of implementing this rigorous serial sampling and analysis program is to ascertain when the pumped groundwater has reached a chemical steady state. Once serial sampling begins, the frequency at which serial samples are collected and analyzed is left to the discretion of the TL. The serial sampling frequency is based upon the site specific conditions existing at each well, but usually is performed a minimum of three times during a sampling round.

The three field parameters of temperature, Eh, and pH are determined by either an "in line" technique, using a self contained flow cell, or an "off line" technique, in which the samples are collected from a nylon sample line at atmospheric pressure. The iron, divalent cation, chloride, alkalinity, specific conductance, and specific gravity samples are collected from the nylon sample line at atmospheric pressure.

New polyethylene containers are used to collect the serial samples from the nylon sample line. Serial sampling water collected for solute and specific conductance determinations is filtered through a 0.45 pm filter membrane using a stainless steel, in line filter holder. Filtered water is used to rinse the sample bottle prior to serial sample collection. Unfiltered groundwater is used when determining temperature, pH, Eh, and specific gravity. Sample bottles are properly identified and labeled.

The filtered sample collected for solute analyses is immediately analyzed for iron and alkalinity, as these two solution parameters are extremely sensitive to changes in the ambient water sample pressure and temperature. The sample aliquot needed for the other chemical parameter analyses may be taken from a second filtered sample bottle. Temperature, pH, and Eh, when not measured in a flow cell, are measured at the approximate time of serial sample collection; these samples are collected from the unfiltered sample line.

Experience gained from the serial sampling of wells has shown that samples to be analyzed for chloride and divalent cations can be stored for one week prior to analysis with confidence that the analytical results will not be altered.

Upon completion of the collection of the final sample suite, the serial sample bottles accrued throughout the duration of the pumping of the well are discarded. No serial sample bottles will be reused for sampling purposes of any sort. However, serial samples may be archived for a period of time depending upon the need. Procedures for sample collection and analysis are generated, approved, and maintained by the site documentation process.

5.6.2 Final Samples 18 WP 02 1 Rev. 3 G RO U N DWATER S U RVEl LLANC E PROGRAM PLAN The final sample is collected once the pumped groundwater has achieved a chemically steady state. A serial sample is also collected and analyzed for each day of final sampling. Sample preservation, handling, and transportation methods are designed to maintain the integrity and representativeness of the final samples.

Prior to collecting the final samples, the collection team must consider the analyses to be performed so that proper shipping or storage containers can be assembled.

Final samples are sent to contract laboratories and analyzed for general chemistry, radionuclides, metals, and selected volatile organic compounds that are specific to the waste anticipated to arrive at WIPP. Gases and redox couples were analyzed during the baseline study, but these data are not needed for environmental monitoring and are no longer obtained on a routine basis.

Water samples are collected at atmospheric pressure using either the filtered or unfiltered nylon sampling lines branching from the main sample line. The samples are collected in new and unused glass and plastic containers.

Before the final sample is taken, all plastic and glass containers are rinsed with the pumped groundwater, either filtered or unfiltered, dependent upon analysis protocol. When the rinsing procedure is completed, the final sample is collected.

5.7 Sample Preservation, Trackina. Packaaina and Transoortation Many of the chemical constituents that are measured are not chemically stable and need to be preserved. Samples requiring acidification are treated with either high purity hydrochloric acid, nitric acid, or sulfuric acid (ULTREX or equivalent), depending upon the standard method of treatment required for the particular parameter suite.

The procedure used by the contract laboratory to which the samples are being sent prescribes the type and amount of preservative which should be used. This information is recorded on the Final Sample Checklist for use by field personnel when final samples are being collected.

The sample tracking system at WlPP uses uniquely numbered Chain of Custody Forms and Request for Analysis Forms. The primary consideration for storage or transportation is that samples must be analyzed within the prescribed holding times for the parameters of interest. Procedures for sample tracking and preservation are generated, approved, and maintained by the site documentation process.

The prescribed transport temperature for the organic samples is four degrees Celsius. This temperature must be maintained until the sample reaches the contracted laboratory.

Insulated shipping containers packaged with reusable blue ice are used to keep the 19 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN samples cool during transport to the contract laboratory. Hold times for specific analytical parameters require samples to be shipped by express air freight. The coolers are packaged to meet Department of Transportation and International Air Transportation Association commercial carrier regulations.

5.8 Qualitv Assurance. Records Manaaernent and Document Control All aspects of quality assurance, records management, and control of documents generated as a result of WQSP are governed by the QAPD; WP 15 PR, Records Management Plan; and implementing procedures generated, approved, and maintained by the site documentation process.

A chemistry laboratory notebook is maintained in the mobile laboratory to record the overall conditions at the well, the analytical difficulties or problems experienced, and any information which may be pertinent to future interpretation and scientific use of the field data. The original notebook is kept in the field laboratory. A copy of the notes made for each sampling round is kept in a fire resistant file cabinet.

All field data collected are organized into a data book. The typical field data book contains the following:

Data collected as a result of WQSP activities are summarized and reported on an annual basis in the Site Environmental Report. Raw data are stored in fireproof cabinets in the EM Section for a period of two years and then turned over to PRS for storage in accordance with the RIDS.

5.9 Calibration Requirements The equipment used to collect data for the WQSP is to be calibrated in accordance with WP 1 0 AD, WIPP Maintenance Administrative Procedures Manual. The metrology laboratory is responsible for calibrating needed equipment on schedule, in accordance with written procedures. The EM Section is responsible for maintaining current calibration records for each piece of equipment.

6.0 WATER LEVEL MONITORING PLAN 6.1 Scoee This section of the WlPP GSP serves as the controlling document for the WLMP. The WLMP is a subprogram of the GSP. The quality assurance activities of the WLMP are in strict accordance with the QAPD and the quality assurance implementing procedures specific to environmental monitoring are found in WP 02 3, Environmental Monitoring Procedures Manual.

Water level monitoring will continue through the postoperational phase of the WIPP. This plan addresses the activities of the WLMP during the preoperational and operational phases of the WIPP. Postoperational activity plans will be formulated at a later date and will address the objectives of water level monitoring as required at the time of decommissioning. .

6.2 Introduction This program will continue the collection and documentation of water level data initiated by the U. S. Geological Survey (Richey, 1987) and SNL (Stensrud et al., 1988) as part 21 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN of the WlPP Site Characterization Program.

As currently planned, water level measurements will be conducted using hydrologic test wells that were constructed for the site characterization and WQSP. These test wells are distributed geographically both within and surrounding the WlPP site. The frequency of measurement is subjectively defined by the need to record the dynamic nature of the potentiometric surface through time.

On October 1, 1988, the ES& H Department assumed responsibility for Groundwater Level Monitoring Activities. At that time a WLMP plan was still being developed. In June of 1989, an initial plan was finalized entitled WP 07 2, WIPP Water Level Monitoring Program Plan, IT Corp. (June 1989). WP 07 2 was subsequently replaced in 1990 by WP 02 1 , Groundwater Monitoring Program Plan and Procedures Manual.

Collection of groundwater level data assists the DOE in meeting performance assessment, regulatory compliance, and permitting requirements. These data also provide:

U 0 0 U 0 0 6.3 Data collection as required by the Environmental Monitoring Plan.

A means to fulfill commitments made in the FEIS.

A means to comply with future groundwater inventory and monitoring regulations.

Input for making land use decisions, (i. e., designing long term active and passive institutional controls for the site).

Assistance in understanding any changes to readings from the water pressure transducers installed in each of the shafts to monitor water conditions behind the liners.

An understanding of whether or not the horizontal and vertical gradients of flow are changing over time.

0 biective The objective of the WLMP is to extend the documented record of water level fluctuations in the Culebra and Magenta members of the Rustler Formation in the vicinity of the WlPP facility. Water level data will also be collected from wells completed in other water bearing zones overlying and underlying the WlPP repository horizon when access to those zones is possible. This includes, but is not limited to, the Bell Canyon Formation, the Forty Niner member of the Rustler, the contact zone between the Rustler and Salado Formations, and the Dewey Lake Red Beds, when access to these zones is possible.

22 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN The scope of the program is subject to change depending upon the following:

a Data trends 0 Performance assessment program needs 0 Environmental Monitoring Program needs 0 Regulatory compliance needs Water level measurements will be taken monthly in at least one accessible completed interval at each available well pad. At well pads with two or more wells completed in the same interval, quarterly measurements will be taken in the redundant wells.

Water level monitoring will continue through the life of the WlPP Project. It may be deemed necessary to temporarily increase the frequency of monitoring to effectively document naturally occurring or artificial perturbations that may be imposed on the hydrologic systems at any point in time. This will be conducted in selected key wells by increasing the frequency of the manual water level measurements or by monitoring water pressures with the aid of electronic pressure transducers and remote data logging systems.

One of the postulated contaminate pathways to the biosphere in the event of a release is believed to be in the water bearing zones of the Rustler Formation, more specifically, the Magenta and Culebra members. The Culebra is believed to be the more conductive of the two (Mercer, 1983) and has received the most attention in site characterization studies. Other water bearing zones in the vicinity of the WlPP site, in which a limited number of hydrologic test wells have been completed, include the Dewey Lake Red Beds, the RustlerlSalado Contact, the Forty Niner Member of the Rustler, and the Bell Canyon Formation. All of the above listed zones will be monitored as part of this program plan, subject to availability.

Water level fluctuations of confined water bearing units may result from a variety of hydrologic phenomena (Freeze and Cherry, 1979) and (Davis and DeWeist, 1966). These include:

1 Changes in groundwater storage (ems., groundwater recharge)

0 Changes in atmospheric pressure 0 Deformation of the water bearing zone (e. g., earthquakes and earth tides)

0 Disturbances within or adjacent to a well (e. g., groundwater pumping and shaft construction)

23 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN Interpretation of water level measurements and corresponding fluctuations over time is complicated at the WlPP by spatial variation in fluid density both vertically in well bores and areally from well to well. To monitor the hydraulic gradients of the hydrologic flow systems at the WlPP accurately, actual water level measurements and the densities of the fluids in the well bores must be known. When both of these parameters are known, equivalent freshwater heads can be calculated. The concept of freshwater head is discussed in Lusczynski (1 961) where the following definition is provided:

Fresh water head at a given point in groundwater of variable density is defined as the water level in a well filled with fresh water from that point to a level high enough to balance the existing pressure at that point. Fresh water heads . define hydraulic gradients along a horizontal.

A discussion explaining the calculation of freshwater heads from midformation depth at WlPP can be found in Haug, et ai. (1987).

A Pressure Density Survey Program (PDSP) has been conducted to determine the actual variation in density gradients existing in the test wells. The PDSP measured the actual midformation pressures of the Culebra. Data from this program have identified those wells in which some adjustment to measured water level values must be accounted for in order to calculate the measured water levels accurately in terms of equivalent freshwater heads.

6.4 Field Methods Po obtain an accurate groundwater level measurement, a calibrated water level measuring device is lowered into a test well and the depth to water is recorded from a known reference point. When using an electrical conductance probe, the depth to water can be determined by reading the appropriate measurement markings on the embossed measuring tape when the alarm is activated at the surface. Specific procedures regarding the specific activities governing the Water Level Monitoring Program are generated, approved, and maintained by the site documentation process.

6.5 Records and Document Control All incoming data will be processed in a timely manner to assure data integrity. The data management process for water level measurements begins with completion of the field data sheets. Date, time, tape measurement, equipment identification number, calibration due date, initial of the field personnel, and equipmenffcomments are recorded on the field data sheets. If, for some unexpected reason, a measurement is not possible (Le., a test is under way that blocks entry to the well bore), then a notation as to why the measurement was not taken is recorded in the comment column. Personnel also use the comment column to report any security observations (Le., well lock missing).

24 WP 02 1 Rev. 3 GROUNDWATER SURVEILLANCE PROGRAM PLAN Data recorded on the field data sheets and submitted by field personnel are subject to guidelines outlined in WP 02 3, Environmental Procedures Manual. The data are entered onto a computerized worksheet. The worksheet calculates water level in both feet and meters relative to the top of casing and also relative to mean sea level.

A check print is made of the worksheet printout. The check print is used to verify that data taken in the field is properly reported on the database printout. A minimum of I O percent of the spreadsheet calculations are randomly verified on the check print to ensure that calculations are being performed correctly. If errors are found, the worksheet is corrected. The data contained on the computerized worksheet are translated into a database file. A printout is made of the database file. The data each month are then compiled into report format and transmitted to the appropriate agencies as requested by the DOE.

A computerized database file is maintained for all groundwater level data. Monthfy and quarterly data are appended into a yearly file. Upon verification that the yearly database is free of errors, it is appended into the project database file. A printed copy of the project database is maintained in the ES& H EM fire resistant storage area current through December of the preceding year.

6.6 ReDortinq Data collected from this program are reported in the Annual Site Environmental Report (ASER). The ASER includes all applicable information that may affect the comparison of water level data through time. This information will include but is not limited to:

1 Well configuration changes that may have occurred from the time of the last measurement (i. e., plug installation and removal, packer removal and reinstallation, or both; and the type and quantity of fluids that may have been introduced into the test wells).

0 Any pumping activities that may have taken place since publication of the last annual report (i. e., water quality sampling, hydraulic testing, and shaft installation or grouting activities).

6.7 Calibration Requirements The equipment used in taking groundwater level measurements is to be calibrated in accordance with WP 10 AD, WlPP Maintenance Administrative Procedures Manual. The WID metrology laboratory is responsible for calibrating needed equipment on schedule, in accordance with written procedures. The EM Section is responsible for maintaining current calibration records for each piece of equipment.

B 1 a ii 1997 Annual Site Environmental Report DOWJPP 98 2225 CHAPTER 7 GROUNDWATER PROTECTION Current groundwater monitoring activities at WIPP are outlined in the Groundwater Monitoring Program Plan and Procedure Manual (WP 02 1, Revision 3). The plan is a QA document that contains program plans for each of the activities performed by ground water monitoring personnel. In addition, WP 02 1 provides detailed pr dures for performing specific activities such as pumping system installations, fiqfjfparameter analyses and documentation, and QA records manage ment. Groundwater monitoring activities are also defined in the EMP.

The objective of the groundwater monitoring program is to determine the physical and chemical characteristics of groundwater; maintain surveillance of groundwater levels surrounding the WiPP facility, both before and throughout the operational lifetime of the facility; and futfili the requirements of the RCRA Part B permit application and DOE Order 5400.1.

Background water quality data were collected from 1985 through the 1990 sampling period to futfill the requirements of DOE Order 5400. A as reported in DOENVIPP 92 013, "Background Water Quality Characterization Report for the Waste Isolation Pilot Plant" In the latter part of 1994 seven new wells were drilled (Figures 7.5 through 7.11) in anticipation of the RCRA permitting process. Background data were collected from these wells from 1995 through 1997 and reported in DOUWIPP 98 2285, Waste isolation Pilot Plant RCRA Background Groundwater Quality Baseline Report." This background data will be compared to water quality data collected throughout the opera tional life of the facility. Preoperational data gathered in the interim period will be used to strengthen the background data, to evaluate the need to make adjustments to comparison criteria, and to determine future regulatory needs and land use decisions.

The data obtained by the WQSP in 1997 supported two major programs at WIPP: (1) the Groundwater Monitoring Program. in compliance with 40 CFR Q 264 and (2) perfQrmance assessment in compliance with 4f& FR § 'IS% Each of these programs requiresa' unique set of analyses and data. Particular sample needs are defined by each pr m. In addition to the characterization of grounhater, the WQSP supported radio nuclide monitoring for the WID Environmental Analysis and Compliance Section. Results of radionuclide sampling are discussed in Chapter 5. Representatives from the EEG were on hand at selected sampling events to collect samples for independent evaluation.

The WIPP site lies within the Pews Valley section of the Southern Great Plains physiographic province (Powers et at., 1978). Geologic and lithologic descn'ptions of the area surrounding the site can be found in documents such as the EMP, the Groundwater Protection Management Program Plan (DOENVIPP 96 2162), and USGS 83 4016 (Mercer, 1983). 'Industries in the vicinity that could potentially contribute to the pollution of the groundwater are potash mining, oil and gas explorationlproduction, and agriculture.

The Culebra is the most significant water bearing unit within the vicinity of WIPP. No known hydrologic connection exists between the repository horizon and the Culebra. Surveillance of hydrological characteristics in the Culebra provides data that can be used to detect changes in water characterization. It also provides additional data for use in hydra logic models designed to predict long term performance of the repository.

Groundwater surface elevation data is gathered from 77 well bores; five of which are equipped with production inflated packers to allow groundwater level surveillance of more than one producing zone through the same well bore (Figure 7.2).

Groundwater quality data were gathered from six wells completed in the Culebra member o f the Rustler formation and one well completed in the Dewey Lake formation (Figure 7.1). The 1997 Annual Site Environmental Report DOEMliPP 98 2225 water quality sampling process has been developed using logistics from groundwater wells originally constwcted for characterization, not intended for groundwater monitoring activities.

Seven wells were drilled in the latter part of 1994 constructed for the explicit purpose of gathering water quality data. Thesgwells are constructed with fiberglass casing and screens that will not bias sample collection. Similar sampling protocols to those used in the past for wells drilled for resource evaluation and site geologic characterization were used through CY 1997. More effiaent sampling methods are being evaluated and should be phased in during CY 1998.

Sampling episodes are referred to as a "sampling round." Each sampling round con sists of the collection of two types of samples: (1) serial samples and (2) final samples. Serial samples are taken periodically while the well is being purged. Key physical and chemical parameters (known as field parameters) are analyzed and compared with past serial sampling data, when available, until a chemical steady state has been reached. A chemical steady state is defined as f 5 percent of the average of the three to five preceding para meter measurements made on the final day of serial sampling from preceding sampling rounds. Stabilition of these field parameters is a function of purging and is used as an indi cator to determine if the groundwater is representative of the zona, bdng sampled. A %a1 sample is collected when it has been determined that the pumped groundwater has achieved a representative state. The sample is then sent off site to a contract laboratory for analysis.

Groundwater monitoring activities during CY 1997 included Groundwater Quality Sampling and Groundwater Level Surveillance.

Groundwater Qualitv SamDling Sampling for groundwater quality was performed semiannually at seven well sites during CY 1997 (Figure 7.1). The wells were 7 2 serially sampled as soon as possible after the pump was turned on to better observe early chemical reactions to pumping. Field analysis for Eh, pH, specific gravity, specific conduc tance, alkalinity, chloride, divalent cations, and total iron were performed on a periodic basis during the serial sampling. These field para meters were used as indicators, during the purging process to better determine when the fonation water being pumped had reached a representative state. Normally this process & quired four to seven days to complete. Following the field analysis of the final serial sample, samples were cokcted and shipped to an independent, contracted, laboratory for analysis. Parameters of art. alysis by the contracted laboratory include the groundwater monitoring list in Appendix IX of 40 CFR Q 264 and those indicator parameters wmrnon to the Culebra member of the Rustler as listed in Table 7.1.

WlPP has not received waste; thekfore no hazardous constituent has been introduced to the environment as a result of WIPP opera tions. Data collected provide background information.

The total gallons of water removed from the Culebra as a resutt of groundwater surveillance activity was approximately 44,318 gallons throughout the year. During the same period 10,962 gallons of water were removed from the Dewey lake formation. Water quality of the Culebra sampled near WlPP is naturally poor and is not suitable for human consumption or for agricultural purposes. The groundwater of the Culebra is considered to be class Ill waters by €PA guidelines. The water contains naturally high concentrations of total dissolved solids and mineral constituents primarily of chloride, calcium, magnesium, sodium and potassium (Mercer, 1983). The high total of dissolved solids concentration has historically posed problems for laboratories performing analysis because the water interferes with the normal operation of standard laboratory equip ment such as Atomic Absorption or Inductively Coupled Plasma, causing estimated quantitation limits to be inconsistent. 1997 Annual Site Environmental Report DOEMIIPP 98 2225 Water quality measurements performed in the Dewey Lake fotmation indicate that the waters are considerably fresher. Samples collected from the Dewey Lake formation are suitable for livestock consumption having TDS values below 10,000 mg/ L. These waters are classi fied as Class II waters according to €PA Guidance. Saturation of the Dewey Lake Formation in the area of WlPP is discontinuous and no hydrologic connection has been established that would indicate that WIPP activities would have an Impact on the Dewey Lake.

Sampling during calendar year 1997 marked the end of data collection for baseline purposes for the RCRA permitting process. A detailed baseline report entitled 'Waste Isolation Pilot Plant RCRA Background Groundwater Quality Report" was issued just prior to the Issuance of the 1997 ASER.

To summarize; this report contains calculated background concentrations for groundwater quality parameters from seven monitoring wells that are located within the boundaries of the WlPP site. From 1995 to 1997, the GMP collected groundwater samples from the Culebra and Dewey Lake water bearing zones in the area of the WIPP site. The GMP has sampled 7 WlPP monitoring wells five separate times. Groundwater was sampled during the GMP from the Culebra Dolomite Member of the Rustler Formation and the Dewey Lake. The GMP focused primarily on the characteriation of Culebra Dolomite groundwater, since the Culebra is the first continuous water bearing zone above the waste repository horizon and is the most transmissive hydrologic unit in the WlPP area.

Because Culebra groundwater chemistry is extremely variable across the WIPP site, areawide background values for groundwater constituents could not be established. Instead, background groundwater quality was defined for each individual well. A minimum of four separate rounds of data from a well was required to establish the background ground water quality at that well. Preliminary analysis categorized GMP data into three groups based on the frequency of detection and the proximity of detections to MDLs. The three groups are as follows:

Major Cations and Anions. Constituents that collectively make up greater than 99 percent of the dissolved solids. These constituents are generatly detected at concentrations that are well above the MOL.

Minor Cations, Trace Metals, Anions, and Indicator Parameters. Constituents with concentrations that are generally less than 10 mglL in groundwater. A substantial amount of the data are below the MDL, and those detected concentrations are generally close to the MDL.

Organic Compounds. Include VOCs, SVOCs, pesticides, and PCBs (all of the parameters induded in 40 CFR 5 264, Appendix IX). Very few detections of these compounds were observed in GMP data.

Given the three data groups defined above, background concentrations were determined and reported in the following manner:

A 95th UTL or 95th percentile confidence interval based on the distribution type was computed for every major constituent from each well. Thus, the expected background concentration for a major constituent at a given well is represented by a 95 percent confidence intewal.

The 95th UTL for most minor constituents could not be calculated due to the large number of NDs; thus, the background concentration range for a minor constituent at a given well is represented by the observed 95th percentile concentration range based on MDLs for that parameter at that well.

Prior to the determination of background concentration values, the GMP data were evaluated for trends. Trend analysis was necessary to determine if any concentrations 7 3 1997 Annual Site Environmental Report DOEMllPP 98 2225 were changing with time due to natural (or non WlPP related) causes. The procedure used to determine background water quality is depen dent on, or somewhat controlled by, the natura of the concentration/ time relationship. In general, temporal trends in concentrations were not found in #$ e GMP data, and the procedure used to establish background water quality reflected this finding. I Additional sampling rounds at each GMP well may provide more insight into potentiat trends in water quality.

The GMP data were also evaluated for potential outliers. Potential outliers were evaiuated through visual examination only. If a value appeared to be an outlier by visual examination, an additional observation was performed to estimate if that value was within G O percent of its nearest neighbor or if it was due to routine analytical uncertainty. Only four values were actually excluded from the major and minor constituent data set prior to the establishment of background concentration summary statistics and box and whisker plots {Figures 7.12 through 7.72).

The following are the specific findings and conclusions of the baseline study:

Some constituents at several wells, including WQSP 1, WQSP 2, WQSP 3, WQSP 5, WQ8P 6, and WQSP GA show potential concentration trends However, in almost every case the trend is within the range of expected analytical uncertainty, or the trend is not supported by charge balance considerations or by similar trends in other constituents, such as TDS.

9 Wells WQSP 4, WQSP 5, and WQSP 6 exhibit concentrations of several para meters that decrease significantly from the first to the second or later sampling rounds. This may indicate that the first sample is not representative, possibly due to incomplete well development and that the wells are "cleaning up" from the initial well installation process. Background groundwater quality was successfully defined for seven wells. Back ground concentrations for major and minor cations, anions, and indicator parameters were e@ blished for Culebra Dolomite and Dewey Lake groundwater. Although the background concentrations of many minor constituents are uncertain, the baseline report documents the "expected" values for these constituents, if similar analytical tech niques are used in future sampling efforts.

Hazardous organic compounds are not present in groundwater in the vicinity of the WlPP site. Detections of these compounds are very infrequent, and the majority of detected compounds are typical laboratory contaminants as defined by the EPA. Some of the occurrences may also be related to well installation or sampling practices.

Specific details on statistical methods and formulas used to reach these conclusions can be found in DOEMllPP 98 2285, "Waste Isolation Pilot Plant RCRA Background Groundwater Quality Base line Report."

Groundwater Level Surveillance In October 1988, WlPP was tasked with conducting a groundwater level surveillance program. Seventy seven well bores are used to perform surveillance of seven water bearing zones in the WlPP area. The two zones of primary interest are the Culebra and Magenta members of the Rustler formation. Fifty nine measurements are taken in the Culebra; and ten, in the Magenta. Three measurements each are taken in the Dewey Lake and Santa Rosa formations. Two measurements are taken in the Rustler/ Salado contact. One measurement each is taken in Bell Canyon, Forty niner, and an unnamed lower member. Locatiort& of groundwater level surveillance sites arszictured in Figure 7.2.

Five well bores are configured to allow monitor ing of more than one formation. These are H 01 CulebralMagenta, H 03d Dewey Lake/ Forty niner, H 16 Dewey Lakehnnamed lower 7 4 1997 Annual Site Environmental Report DOElWtPP 98 2225 member, WIPP 25 CulebralMagenta, and WIPP 27 CulebralMagenta.

Groundwater surface elevations in the vicinity of WlPP may be influenced by site activities such as pumping tests for site characterization, water quality sampling, or shaft sealing. Other influences on groundwater surface elevations may be caused by natural groundwater level fluctuations and industrial influences from agriculture, mining, and resource exploration.

Groundwater elevation measurements in the Culebra indicate that the generalized directional flow of groundwater is north to south in the vicinity of WIPP (Figure 7.3). Regional groundwater levels taken ' in 43 Culebra observation wells with more than four data points for the year show increases in water levels occurred in 26 wells and 17 wells showed a decrease in water levels over the period of January 1997 through December 1997. During this period 23 wells had net water level increases or decreases of less than one foot Total fluctuation of more than one foot in groundwater levels occurred in 33 of the wells. Nine wells with fluctuations of more than one foot (WQSP 1 through WQSP 6, H 19b0, H 18, and H 14) may have been influenced by groundwater quality sampling activities. Four wells (ERDA [United States Energy Research and Development Administration] 9, WIPP 18, WIPP 19, WIPP 21, and WIPP 22) may have been influenced by site activities.

Water level increases originating to the south of the site in the H 9 area and extending up gradient toward the site are currently unexplained. Studies are currently being conducted to try and explain the anomalies.

Groundwater flow directions in' the Magenta appear to be generally from an east to west direction across the WIPP site (Figure 7.4). Regional groundwater level measurements taken in the Magenta dolomite indicate that water levels are increasing in wells located near the center of the site, while water levels near or outside the WlPP boundary appear to be relatively stable. One well H 01 has had anomalus water level increases and appears to be influencing the wells in the immediate vicinity (H 2bl and H 3bl). The cause is as yet undetermined.

The WWlS is specified and required by the Compliance Certification Application for the Waste Isolation Pilot Plant (DOEKAO 1996 21 84, Title 40, Code of Federal Regulations [CFR], Section 191 ); the Transuranic Waste Characterization Quality Assurance Program Plan (CAO 94 1 01 0); the WIPP Resource Conservation and Recovery Act (RCRA) Part B Permit Application, Chapter C, Waste Analysis Plan (DOEMIPP 91 005); and the Waste Acceptance Criteria for the WlPP (DO ENVl PP 069).

2.0 SCOPE This WWlS Program addresses the entire range of activities performed by the WWIS. Data received by the WIPP for waste acceptance purposes is used to determine compliance with t h e RCRA Part B Permit Application and 40 CFR 0194 requirements. Since no physical analysis of waste will take place at WIPP, the data management, review, and approval processes are critical to ensure WIPP's regulatory compliance.

The W l S is an on line database system used to:

Record waste container characterization and certification data supplied by the transuranic (TRU) waste generators, as required by the WIPP Waste Acceptance Criteria (WAC), to gain acceptance for disposal at WlPP Print a Summary Report that provides a listing of waste container characterization data for use in review of Waste Stream Profile Forms (WSPF) associated with the container characterization data Provide computerized hold and approval points for the WlPP data administrator regarding WlPP acceptance of container characterization and certification data Communicate the approval/ rejection status of characterization and certification data to the generatorkhipper Record proposed shipment configuration details from the generatorkhipper for containers that have received WIPP approval of characterization data Provide a hold and approval point for the WlPP data administrator to approve or reject the proposed shipment 1 WlPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 Communicate the approvaI/ rejection status of proposed shipments to the g eneratorlsh i p per Provide a Shipment Report for WlPP personnel to verify the "as received" shipment against the information listed on the manifest accompanying the shipment, and to verify that containers received are those approved by WlPP for shipment Record the disposal location of the containers when they are placed in the underground disposal area Record (automatically) any changes made to WWIS data, record changes, and provide a Change Log Report to identify changes that have been made Provide required reports, which are entered into the facility operating record and kept as a quality record for the lifetime of the facility The above functions require the interaction of several groups within Waste Operations, and with generatodshipper sites and others, such as internal and external review/ oversight groups. his program defines the responsibilities and activities for each group of WWlS users at WIPP.

3.0 RESPONSIBILITIES 3.1 Waste Operations The Waste Operations Section is the organization with cognizance over the waste acceptance and emplacement process at WIPP. The review and approval of waste data is coordinated by Waste Operations and all records generated by the review and approval process are controlled by Waste Operations until transferred to Project Records Services.

The WWlS data administrator is responsible for establishing access authorization to the WWlS for generatodshipper sites; approving user characterization data, certification data, proposed shipping data, and maintenance of Administrative Reference Tables used in WWlS operation; deleting generator data records when requested by the generator (the WWIS Change Log Records record deletions archived as a part of the overall database process); and assisting users with problems associated with the application.

2 WIPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 The data administrator is also responsible for the following activities regarding WWIS operation:

D D *

I D Determine the need for access, assign user identifications and enter them into the W l S Determine acceptability of waste container data submitted by the generator in the WWlS Characterization Module for WSPF approval Designate approved WSPF numbers in the WWlS Administration Tables Determine acceptability of waste container data submitted by the generator in the WWlS Certification Module Enter needed data into €he Reference Data Tables of the WWlS Process WSPF( s) to the requirements of the Waste Stream Profile Form Review and Approval Program (WP 05 WA. 03)

Produce reports from the WWlS Enter approved changes to the W I S data Assist generators with data entry problems Serve as the contact point at WlPP for the generator sites regarding data transmittal and submittal Hazardous Waste Operations is responsible for:

Initially receiving the TRUPACT II shipment Signing the manifest Reviewing WWlS data to determine if it agrees with information on the Shipment Manifest Notifying the Waste Handling engineer of the manifest review results Resolving manifest discrepancies by working with the WWlS data administrator and the generatodshipper 3 WlPP Waste information System Program WP 05 WA. 02, Rev. 0, Chg. 2 The Waste Handling engineer is responsible for two primary entry inputs to the WWIS:

Recording acceptance of the shipment in the WWlS after verifying that the correct containers were received, based on shipment information in the WWIS and Shipment Manifest information Recording off loaded container information and container disposal locations ' 3.2 Resource Conservation and Recovery Act Permittinq The RCRA Permitting Section reviews each WSPF and the associated Characterization Data Summary Report, then completes a checklist to document that review per WP 05 WA. 03. A specific focus of this review is to ensure that the requirements of the WlPP Waste Analysis Plan are properly implemented. RCRA Permitting also performs periodic reviews (on a selected or "as necessary" basis) of generator waste container characterization data entered into the WWIS. Cognizant R C W Permitting personnel have access to the WWIS database for use in review of administrative information, waste characterization data, certification data, decay analysis, change log, inventory, and regulatory reporting.

3.3 Qualitv and Recrulatorv Assurance Quality and Regulatory Assurance (Q& RA) participates in the review and approval activities for the WSPF to verify that the submittal is complete and properly signed. On a selective basis, Q& RA will review waste container data submitted to WIPP through the WWlS by the generatorkhipper sites to determine if the generator data entered into the WWIS is complete.

3.4 Proiect Record Services Project Record Services is responsible for t h e retention of records generated by the WlPP waste acceptance process. Some of the records generated by this process will be retained at the facility as a part of the operational record until closure of the facility. Other records will be sent to records storage. Criteria to define the record retention times are listed in the approved Records Inventory and Disposition Schedule and the implementing procedures for each document.

4 WlPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 3.5 Information Svstems DeveloDment Information Systems Development (ISD) is the support organization for the VWVIS. ISD is responsible for keeping the WWlS functional and facilitating electronic communications between WlPP and the generator sites. ISD also provides a secure area for the WWlS server; performs nightly, quarterly, and annual backups of system records; and maintains network communications.

3.6 Technical Traininq The Human Resources Technical Training Section is responsible for controlling and maintaining the W I S Qualification Card. The qualification cards are used as part of the WlPP qualification program and will be maintained, controlled, and retained per the implementing procedures. The Waste Operations data administrator (the Subject Matter Expert) will aid Technical Training personnel in the development of the WWlS Qualification Card.

3.7 TRU Waste Proarams The Engineering TRU Waste Programs Section provides the cognizant engineer (configuration manager) for the WWlS Program. The cognizant engineer is responsible for providing design and configuration management for the WWlS database and represents the primary source of engineering interface for the WWIS. Configuration management is addressed in approved Waste Isolation Division (WID) management procedures.

3.8 Department of EnerclvlCarlsbad Area Office The Carlsbad Area Office manager is responsible for granting, or suspending, a site's authority to certify TRU waste to the WAC (certification authority) and to use the TRUPACT II and Remote Handled TRU 72€ 3 Cask (transportation authority) based upon an assessment of their documented TRU waste program and its implementation. After approving the required generatorkhipper plans, the CAO, together with the managing and operating contractor, will perform certification audits of the generator/ shipper sites to assess the implementation of, and compliance with, the approved plans. Based upon acceptable results of the certification audit, the CAO will grant TRU waste certification authority and transportation authority to the site.

The CAO is also responsible for review and approvalldenial of generatorlshipper site requests for exceptions (variances) to the WlPP operations and safety requirements. The CAO cannot approve exceptions to requirements that are confrored by others, such as the Nuclear Regulatory Commission WRC), for transportation or the Environmental Protection Agency (EPA) and ine New Mexico Environment Department (NMED) for the RCRA component of TRU mixed waste, without first obtaining changes to the controlling permits.

5 WlPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 4.0 WWlS ACCESS The hardware for the W l S system is located in a controlled access area within the WlPP facility. Computer access to the W l S database is controlled by means of user identifications and passwords assigned to users having a need to use the waste information system. A user must obtain authorization from the WlPP data administrator before being allowed to log onto the electronic system. Prior to granting user access, the data administrator will instruct potential users in the proper use of the WWIS. When the authorization is granted, read/ write access restrictions are also imposed on the user to ensure that the integrity of the data within the database is maintained.

4.1 User Access The WWlS data administrator receives requests for system access from users on the WWIS Access Request Form (Attachment I).

Generatorkhipper sites must be certified by the CAOWIPP prior to entering waste data into the W l S for review by the WIPP. The data administrator reviews the WWlS Access Request Form and approves or disapproves the requested authorization reason for access (designated in Attachment 2), signs the WWlS Access Request Fom, and forwards the request to the Waste Operations manager for final approval.

After obtaining the approval of the Waste Operations manager, the data administrator provides instruction to the requestor on the proper use of the WWIS, enters the access type onto the WWlS Access Request Form, and makes the necessary entries into the WWIS Administration Reference Tables to allow the user access to the WWIS. Access restrictions are imposed as defined in the Software Requirements Specification and the Software Design Description, and are documented on the approved WWlS Access Request Form.

The data administrator will advise the user when the approved access to the WWlS has been established by providing the user with a copy of the signed WWlS Access Request Form. The signed W l S Access Request Form will be transmitted to the user as an attachment to the W l S Access Notification Form (Attachment 3). The data administrator will file a copy of the WWlS Access Notification Form and attached W I S Access Request Form in the WWlS project files.

The data administrator will revoke any access privileges at the request of the user or Waste Operations manager by accessing the Administrative Reference Tables and inserting an access termination date equal to the date of revocation.

6 WIPP Waste information System Program WP 05 WA. 02, Rev. 0, Chg. 2 5.0 WlS COMPONENTS The W I S database is a complex, multifaceted database system designed to perform functions ranging from retaining simple data; providing a platform for the review/ approval of generator/ shipper sites waste information; tracking of waste containers by categories; combining containers into packages and shipments; and to verify emplacement location of the containers in the repository. To fulfill the variety of tasks assigned to the W I S , the database system is divided into several modules. These modules, other components, and organizationallindividual responsibilities are described below.

5.1 Administration 5.1.1 Administrative Tables The WWIS has an extensive library of Administration Tables. These tables, used by the data administrator, contain complexwide requirements specified in DOENVIPP 069 and CAO 94 1010. Also included in the tables are site specific information listed in CAO approved generatorlshipper site Quality Assurance Project Plans, Certification Plans, TRUPACT II Authorized Methods for Payload Control (TRAMPAC), and data supplied to WlPP regarding individual containers, waste streams, and shipping informat ion.

5.1.2 User Administration The user administration function is the responsibility of the Waste Operations data administrator. The data administrator is responsible for maintaining WWlS data pertaining to individual users of the system. This includes updating user data files (information about the users), setting up access for new users to the application, instructing personnel in the proper use of the W I S , assisting users with problems associated with the application, defining the extent of use of the system for each user, and deleting users from the application.

5.1.3 Data Administration The data administrator is responsible for determining user access to the data, administering Reference Tables used systemwide, producing reports from the Reference Tables, and logging changes. The WWlS is capable of producing several standardized and specialized reports concerning the waste data supplied by the generatorkhipper site. Internal and external requests for these reports will be processed by the data administrator on the basis of the nature of the request, the availability of resources to perform the request, and the approval of Waste Operations management. The data administrator updates tables containing limit and reference data and provides change information to the Change Log.

7 WlPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 5.1.4 Security The Waste Operations data administrator controls access to the databases and data through passwords, and controls access to the data at the record level. AIf data transmitted between the W l S server located at the WlPP and the WWlS and elsewhere will be via the limited access Departmen1 of Enerav Business Network /DOE BN). Users are assigned access authorization levels as listed in Attachment 2. Users are only allowed to view data pertaining to their access authorization level and/ or site.

5.2 Characterization Module The Characterization Module allows the generatodshipper to enter specific container information to be used to validate the characterization activities of the generator site for the data summary on the WSPF submitted for WlPP approval. Approval of the WSPF will be required before waste containers associated with the waste stream can be approved and accepted.

Required information fields for the characterization data input are indicated by a shaded entry box on the interactive input screen for manual input. For electronic data input, data information is defined in data structure tables included in the WWlS User's Guide.

After the data passes the limit and edit checks and is reviewed by the W l S data administrator, it is considered "acknowledged" data. An entry is made by the WlPP data administrator, making the data available for viewing to the generator only through the Certification Module pull down screen. The generatodshipper is denied any further write access to the information fields of the Characterization Module at this point.

This module has provisions to generate a WWlS Waste Characterization Data Report, which contains a listing of the characterization data for the containers covered by a WSPF. A copy of this report will be attached to the WSPF to support the review of the information.

Container data not accepted by W l S in this module will not be retained by the WVVIS. A Bad Data Report will be created and will explain the reason( s) for rejection. Rejected data will require resubmittal to WlPP prior to further consideration.

5.3 Certification Module The Certification Module allows for generator transmittal and WlPP data administrator verification of submitted WAC data. All modifications to the data will be tracked in a Change Log. In this module, the data administrator will accept or reject certification 8 WIPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 data and provide verification reports. After acceptance of the submitted data, the WWlS will automatically generate an Acceptance Report. If the submitted Certification Module data is rejected, the data administrator will generate a Rejection Report and notify the generatorlshipper site.

Required information fields for certification data input are indicated by a shaded entry box on the interactive input screen for manual input. For electronic data input, data information is defined in data tables included in the WWlS User's Guide.

After the data passes the limit and edit checks and a review by the W l S data administrator, it is considered "acknowledged" data and an entry is made by the WIPP data administrator. The generatorkhipper is denied any further write access to the information fields of the Certification Module at this point.

5.4 Shitminu Module The Shipping Module allows the generatorlshipper to propose a shipment configuration for WIPP approval. The proposed shipment information is entered into the WWlS and subjected to data limit checks to determine if the shipping requirements of the TRAMPAC and WIPP WAC are met by the proposed shipment.

After passing these electronic data checks, the shipping information is reviewed by WIPP operating personnel. If everything is in order, the shipment data is approved and the generatorlshipper may proceed with the shipment.

This module generates the Shipment Summary Report used by Waste Operations to verify that the correct containers have been shipped.

5.5 lnventorv Module The inventory Data Module is designed for WIPP to record what containers have been received, the receipt date, and the disposal locations for those containers.

This module generates the Container Emplacement Report, which will be kept as part of the facility operating record. The Inventory Data Module also generates other reports concerning the disposed waste inventory, including reports on nuclides, container data, headspace gas, and biennial information.

6.0 USING THE WWlS Each module and component described above requires input from several users, such as the generatorkhipper, data administrator, and others. From these modules and Administrative Tables, the WWIS has the capability of generating various reports to track the input from t h e generator/ shipper sites. These reports are listed and described 9 WIPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 in WP 05 WA. 01, WlPP TRU Waste Data Management Plan. The methods to be employed in the completion of each module of the WWlS database are described and defined below.

6.1 Electronic Data Entry  Characterization Module Prior to review of generatorlshipper characterization data, the data administrator will ensure that the DOE/ CAO has granted certification and transportation authority to the generatorjshipper site as stated in Section 3.8.

Generatorskhippers must notify the WWlS data administrator of new WSPF numbers prior to inputting Characterization Module container data associated with that profile number. After notification of the new numbers, the data administrator will enter the proposed WSPF numbers in the WWlS Administration Reference files, but will leave the approval date blank (indicating that the WSPF is not yet approved). No generatorlshipper site waste data will be accepted by the WWlS database until the data administrator has updated the Administrative Reference Tables to include the WSPF number.

Electronic transfer of characterization data is granted to sites that have an electronic waste information system. The data from the user system must be formatted to be consistent with the WWlS data structures as listed in the WWlS User's Manual (SP WO WlS 002). Before data is transmitted, the user system formatting wit1 be verified to ensure integrity. The WWlS data administrator will transmit the system format and assist the user with the setup of the data structure. The WWlS system performs edit and range checks on the characterization data and identifies all errors by waste container identification number. After electronic transmittal of characterization data to the W I S , the generators/ shippers are only allowed to view their packages and/ or print error reports. After the characterization data has passed alf range and edit checks and has been approved by the Waste Operations data administrator, the shipper will receive a message to that effect.

6.2 WWlS Database Use in Amrovinu the WSPF The review and approval of WSPFs are governed by WlPP approved procedures. After receipt of the WSPF from the generator/ shipper site, Waste Operations routes a copy of each WSPF and associated WWlS Characterization Data Summary Reports from the WWlS to RCRA Permitting and Q& RA. The Summary Report provides reviewers with a listing of waste container characterization data associated with the WSPF. These organizations review the form against requirements of the WlPP Waste Analysis Plan, the Quality Assurance Program Plan, and the WlPP Quality Assurance Program Description.

After the reviewers have completed their reviews, a meeting may be called by Waste Operations if any profile deficiencies are noted. Waste Operations interfaces with the 10 WlPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 generatodshipper to resolve any noted deficiencies. After all WlPP reviewers concur that the WSPF is acceptable, Waste Operations notifies the generatorlshipper of the WSPF approval. The WlPP data administrator makes an approved date entry into the WWlS data Reference Tables, causing the program to recognize the approved profile number. This entry is necessary for the data to be accepted into the WWIS Certification Module.

When the WSPF is routed for review, it is tracked by a routing slip and is recorded into a log of the WSPFs received by the WlPP in accordance with WP 05 WA. 03.

A critical part of waste stream approval is the WlPP RCRA Specific Generator Site Waste Screening and Acceptance Audit Program Plan, (WP 02 PC. 01). After the initial audit and approval, annual audits are performed for sites shipping waste to WIPP. The data administrator ensures that the waste generator has successfully passed the scheduled CAO certification and WlPP RCRA specific audits and resolved any significant deficiencies before approving a WSPF from that site.

6.3 Manual Data Entrv  Characterization Module Manual characterization data entry access is granted to generatodshipper sites that have limited or small quantities of TRU waste, or that do not have an electronic information system but do have access to the WWlS database capabilities. Manual data entry allows a generatorlshipper site without an electronic waste information system to enter waste data directly into the various blocks of the characterization data entry screens. Although the manually entered data process is much slower than that of electronic data transfer, the entered waste data receives the same editllimit checks and reviews as electronic data transfers.

Generatordshippers must notify the W l S data administrator of new WSPF numbers prior to inputting Certification Module container data associated with that profile number. After notification of the new WSPF numbers, the data administrator will enter the proposed numbers in the WWlS Administration Reference fifes, but will leave the approval date blank (indicating that the profile is not yet approved). No generatodshipper site waste data will be accepted by the WWlS database until the data admini strator has updat ed the Admin ist rat iv Refer ence Table S. e 11 WlPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 6.4 Review and ADDroval of Characterization Data Entries The data administrator periodically reviews container Characterization Module data that have passed the WWlS datallimit checks. The review requirements are at the discretion of the data administrator but are primarily performed for consistencv with the Waste Stream Profile Form.

After review of the data, the data administrator will indicate acceptance or rejection of each container characterization record on the acceptheject screen feature in the WWIS. If the record is rejected, the data administrator will input the reason for the rejection into the WWlS and notify the generator/ shipper of the reason for rejection.

6.5 Electronic Data Entrv  Certification Module The electronic transfer of certification data is granted to sites that have electronic waste information system capabilities. To use the WWlS electronic data option, the data from the user system must be formatted to be consistent with the WWlS data structures. Before data are transmitted, the user system formatting will be verified by acceptance testing of the generatorishipper electronic data system to ensure integrity and compatibility with the WlPP WWlS server.

The WWlS system performs edit and range checks on the data and identifies errors by waste container identification number. After electronic transmittal of certification data to the WVVIS, generators/ shippers can only view their certification packages and/ or print error reports. After the data have passed all range and edit checks and received approval from the Waste Operations data administrator, the generator will receive an electronic message to document the approval.

6.6 Manual Data Entrv  Certification Module Manual certification data entry access is granted to generator/ shipper sites which have limited or small quantities of TRU waste or which do not have an electronic information system but do have WWIS database capabilities. Manual data entry allows a generator/ shipper site without access to an electronic waste information system to enter waste data directly into the various blocks of the WWlS Certification Module data entry screens. Although the manually entered data process is much slower than that of electronic data transfer, the entered waste data receives the same edit/ limit checks and reviews as electronic data transfers.

This module is structured to accept only data that pertains to accepted waste stream profiles. This allows the generatorkhipper to enter waste container data for approval of the individual containers. The data will be screened by the WWlS to perform limit checks for each data entry. Data outside the range limits of the WAC will be rejected 12 WIPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 by the database.

6.7 Review and Approval of Certification Data Entries The data administrator will periodically review container Certification Module data that have passed the WWlS datallimit checks. The reviews are at the discretion of the data administrator but are primarily performed for consistencv with the Waste Stream Profile A Form After review of the data, the data administrator will indicate acceptance or rejection of each container characterization record on the accepffreject screen feature in the WWIS. If the record is rejected, the data administrator will input the reason of the rejection into the WWIS. The W I S automatically notifies the generatorlshipper site of the rejection.

6.8 Electronic Data Entrv  ShbDina Module The electronic transfer of shipping data will be granted to sites that have an electronic waste information system. The data from the user system must be formatted to be consistent with the WWlS data structures. Before data are transmitted, the user system formatting will be verified by acceptance testing of the generator electronic data system to ensure integrity and compatibility with the WlPP WWIS server. Edit and range checks are performed by the W I S . The data entered are descriptors by waste container or dunnage container and include shipment, packaging, and assembly information.

6.9 Manual Data Entrv  ShipDina Module Manual shipping data entry access is granted to generatorkhipper sites which have limited or small quantities of TRU waste or which do not have access to an electronic information system but do have WWlS database capabilities. Manual data entry allows a generatorkhipper site without an electronic waste information system to enter waste data directly into the fields of the WWlS Shipping Module data entry screen. Although the manually entered waste data process is much slower than that of electronic data transfer, the entered waste data receives the same edifflimit checks and reviews as electronic data transfers.

6.10 Review and ApDroval of ShiDDina Data Entries After the generatorlshipper site has entered the required Shipping Module entries, the WlPP data administrator will review the data to ensure that it is complete and passes the WWlS electronic data checks. The data administrator will additionally verify and document on Attachment 4, ushipping Review of Cellulose, Plastics and Rubber 13 WlPP Waste information System Program WP 05 WA. 02, Rev. 0, Chg. 2 (CPR), n that the amount of the material parameters contained in the shipment will not cause the WlPP repository inventory of cellulose, plastics and rubber to exceed the limit of 2x107 kgs. After these checks have been completed, the data administrator approves the generatorkhipper site shipping data entries by selecting the "accept" field on the WWlS "ReviewlApprove Shipment Information" screen. This approval allows the generatorkhipper site to proceed with preparing the proposed shipment for transport to WIPP.

6.11 Shioment ReceiDt Data Prior to bringing a TRUPACT II shipment into the Waste Handling Building, the Waste Handling engineer will print a Shipment Summary Report for use in preparing for the shipment unloading. This report is used by the Waste Handling engineer and Hazardous Waste Operations to provide a summary of parameters important to waste receipt and planning considerations.

6.12 Barcode Data Check of Shioment  Received Containers The following information will normally be gathered using a programmed WWIS interface for downloading information to the barcode scanner, but the information can be manually recorded and compared to the information in the Shipment Summary Report. Data input to the WWlS can be accomplished by keyboard input of container barcode numbers and disposal/ storage locations. The W l S contains screens which allow manual input of the inventory and location information if the barcoding equipment is not available.

The Waste Handling engineer will place the barcode scanner in the connect cradle and downtoad shipment information to the scanner.

The Waste Handling technician will scan a container barcode from each assembly after it is removed from the TRUPACT II. (The WWlS program will associate the barcoded container with the seven pack assembly number and any of the remaining drums of the assembly.) The programmed scanner will indicate if the scanned container is listed in the approved shipment information. (After matching the scanned container number with the number in the WWIS, shipment approval may proceed.)

If the scanner identifies the container number as incorrect, the container will be scanned again. If the number is not recognized in the second scanning, the Waste Handling engineer will be notified.

The Waste Handling engineer will notify the Waste Operations manager and Hazardous Waste Operations that the shipment container number does not agree with the shipment summary information. It is the responsibility of Hazardous Waste Operations to resolve any manifest discrepancies by working with the W l S data 14 WlPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 administrator and the generatorkhipper.

6.13 ShiDment Approval The Waste Handling engiileer will notify Hazardous Waste Operations if the w c d d container( s) agree with the WWlS Shipment Summary and obtain their recommendation for approval or disapproval of shipment, based on agreement with manifest *formation.

After ysrifying agreement between the WWlS Shipment Summary and the Hazardous Was6 Manifest from Hazardous Waste Operations, the Waste Handling engineer will indicate acceptance of the shipment by selecting the shipment "accept" screen festure of the WWIS. I f the WWIS Shipment Summary and the Hazardous Waste Manifest are not in agreement, the Waste Handling engineer will notify the Waste Operations manager before making a shipment rejection entry into the WWlS (this is expected to be a rare event).

6.14 Recordina Overpack Information If Waste Handling Operations finds it necessary to overpack waste containers (Le., loading corroded, damaged, or contaminated containers into a larger container), the Waste Handling engineer will access the WWlS Overpacked Container input screen and record the overpacked container (i. e., drum or Standard Waste Box [SWS]) configuration information.

Disposal location information will be recorded, using the same procedures used for non overpacked containers.

6.15 Barcode Data Entrv  Location of DrumlAssemblies The Waste Handling engineer can establish valid storage locations (room and panel) by updating the pull down screen in the Inventory Module of the WWlS prior to disposal.

Waste containers may not be taken underground for disposal until the Waste Handling engineer has accepted the shipment, as indicated by the Shipment Approval in the WWIS. _.

6.16 Container DisRosal Data The Waste Handling engineer will place the underground barcode scanner in the connect cradle and download shipment information to the scanner. The Waste Handling technician can enter the disposal location, including panel and room, into the barcode scanner for each assembly.

15 WIPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 After disposal locations for assemblies of the shipment are recorded in the barcode scanner, the Waste Handling engineer will upload the location information from the barcode scanner to the WWIS. Data errors in the module are listed in the "Bad Location" screen of the WWIS.

After uploading the location information, the Waste Handling engineer will review the bad location screen of the WWIS, if necessary, and correct any locations that were found to be incorrect.

The data administrator will print a Waste Container Emplacement Report weekly to document updated emplacements performed during the reporting period. This report is added by the data administrator to the WWlS Operational Log and retained at WlPP for the operational life of the facility.

7.0 SETTING UP OTHER SITES TO USE THE WWlS The Waste Operations data administrator provides the generatorlshipper sites with several levels of assistance in setting up generator/ shipper sites with the WWlS database. Services provided to the generatorlshipper sites include:

a a a a e e 8.0 Providing users' computers with the necessary W l S client files Making appropriate entries in the WlPP W l S to establish identifications for the designated sites and users Providing data structure tables for sites to populate with site waste data (for electronic data entry)

Providing WWlS database user training (on the job training) for generatorlshipper site data entry personnel Providing the generator/ shipper sites with a user's manual Providing site support visits by the data administrator and programming support personnel Providing telephone support each workday during work hours Providing the site with an acceptance test to qualify the site system in the transmittal of data from the site to the WlPP WWlS EXCEPTIONS AND UNRESOLVED SAFETY QUESTION DETERMINATIONS 16 WIPP Waste Information System Program WP 05 WA. 02, Rev. 0, Chg. 2 Requests for exceptions (variances) to the WlPP operations and safety requirements must be formally submitted to the CAO for approval. The CAO cannot approve exceptions (variances) to requirements that are controlled by others, such as the NRC for transportation, or the EPA and the NMED for the RCRA component of TRU mixed waste, without first obtaining changes to the controlling permits. An exception may be allowable since the stated limit is an average based on the average concentration in a room divided by the number of containers emplaced in the room. The typical drum Volatile Organic Compound (VOC) concentration will be well below the established maximum average concentration. An evaluation can be performed at the time of the generatots request for the exception to ensure that the addition of a drum with a VOC concentration greater than the maximum average will not cause the concentration in the room to exceed the maximum average limit.

Unreviewed Safety Question Determinations are performed by WID per WP 12 ARlOOI. Unreviewed Safety Question Determinations are conducted to determine the impact of proposed waste data that is outside the current limits of the WAC and compares the impact to the margin of safety in the WlPP Safety Analysis Report.

The data administrator, upon written notification of a CAO approved Exception Request and receipt of an acceptance of the proposed change by Environment, Safety, and Health, will update the WWlS WAC Exception Table with the WAC exception number, package identification, and the new limits for the field allowed in the exception.

9.0 DATA CHANGE CONTROL The data administrator is responsible for WWlS data management and change control. The W I S has several methods of identifying, documenting, and controlling the changing of generator/ shipper site waste data. These methods include:

Rejecting container data not accepted by WWlS in the Characterization Module or Certification Module (a Bad Data Report will be created, explaining the reason for reject ion)

Resubmitting rejected data will require correction and resubmittal to the WlPP prior to further consideration a ?hanging the approval status after completion of each review and approval stage, defining which module can be used to gain access to the data Deleting a record, if a record change is required by the generatorkhipper after the approval process has begun (the WIPP data administrator deletes the record after recording the reason for the deletion in the Change Log and places a copy of the deleted record in the database Change Log for future reference)
