The investigation is being performed at the request of the United States Environmental Protection Agency (USEPA). The investigation will consist of three main tasks: • groundwater screening using direct push technology (DPT); • monitoring well installation, if warranted, based on the results of the DPT investigation to enhance the monitoring well networks in the area of F-55 and/or K-28; and • monitoring well installation between F-55 and the inner tier well network. Additionally, quarterly groundwater sampling events will be performed during 2006 on selected wells to obtain natural attenuation data and to comply with USEPA Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) sampling requirements for the site. The remainder of this Work Plan details the procedures and methodologies that will be used to assure the quality of the data collected during the investigation. 1,1 OBJECTIVES The objectives of the investigation are as follows: Direct Push Technology (DPT) Installation • To delineate the horizontal extent of ethylene glycol in groundwater downgradient (east- southeast) of monitoring well F-55 that is located along the eastern perimeter of the plant production area. • To evaluate if existing downgradient wells are adequate to monitor increasing concentrations of ethylene glycol in monitoring well K-28 that is located north of the northernmost emergency pond. • To support future remedial efforts focusing on monitored natural attenuation (MNA). Monitoring Well Installation • Based on the results of the DPT installation, additional monitoring wells may be installed to complete delineation of the downgradient extent of the ethylene glycol plumes in the areas described above. • Additional monitoring wells will be installed between monitoring well F-55 and the inner- tier well network to ensure the adequacy of the monitoring well network. • The new monitoring wells will be used to support future remedial efforts focusing on MNA.

The DPT borings will be installed to • delineate the extent of ethylene glycol in groundwater • evaluate the adequacy of existing wells to monitor the ethylene glycol plumes in these areas. A map showing the proposed DPT locations is provided as Figure 1. The DPT borings will be completed and will be collected at depths of approximately: • 50 to 75 feet below ground surface (bgs) in the area of monitoring well F-55. • 20 to 40 feet bgs in the area of monitoring well K-28. 3.1 DPT GROUNDWATER SAMPLING PROCEDURES Groundwater samples will be collected approximately 5 feet below the top of the groundwater surface and at approximately 15-foot intervals thereafter to either probe refusal or a maximum depth of either 40 or 75 feet bgs, as described in Section 3.0 above. During DPT groundwater sampling, the field geologist will document the sample collection in a field notebook. The samples will be collected through the DPT rods using small-diameter, bailers or a peristaltic pump, if appropriate. The DPT groundwater sampling procedures are described in Appendix B. 3.2 DPT GROUNDWATER SAMPLE ANALYSIS DPT groundwater screening samples will be analyzed for ethylene glycol. In addition, DPT groundwater samples collected from the F-55 area will be analyzed for tetrahydrafuran (THF) and 1,4-butanediol, if sufficient sample volume can be obtained. The THF and 1,4-butanediol are indicators of specific plant operations and will be used to help identify the source of the ethylene glycol. A summary of the groundwater sampling methods, holdings times, sample preservation, and sample volume for the required method is presented in Table 1. 3.3 GROUNDWATER SAMPLE QUALITY CONTROL (QC) SAMPLES DPT groundwater QC samples will include equipment blanks, trip blanks, and duplicates. Duplicate samples will be collected at a rate of 5% of the total sample volume. A trip blank will be included with each shipment to the laboratory. One equipment blank will be collected per day of field operations.

The wells will be installed in areas identified by the DPT that require additional monitoring, or further evaluation for MNA. In addition, monitoring wells will be installed between monitoring well F-55 and the inner-lier monitoring wells The exact locations for monitoring wells will be established based on the results of the DPT investigation. 4.1 MONITORING WELL INSTALLATION AND CONSTRUCTION The monitoring wells will be installed using hollow stem auger drilling methods. The borings for the monitoring wells will be a minimum of 6 inches in diameter and will be installed to an approximate depth of 30 to 60 feet bgs. The wells will be constructed of 2-inch, schedule 40, PVC casing, and 0.01-inch slotted, schedule 40, PVC, well screen. The field geologist will document the well construction on the Well Construction Summary form that is included in Appendix A and in a field notebook. During well construction, water level measurements will be collected using an electronic interface probe that is capable of detecting both water and free product. Water level measurement procedures are described in Appendix D. The monitoring well installation and construction procedures are detailed in Appendix E. 4.2 MONITORING WELL DEVELOPMENT The drilling contractor will develop the monitoring wells by surging and pumping with an electrical submersible pump. Earth Tech personnel will be present during development to collect groundwater quality parameters. Documentation of the well development will be recorded on the Well Development Form that is included in Appendix A, and in a field notebook. The well development procedures are detailed in Appendix E. 4.3 MONITORING WELL SAMPLING The details of the monitoring well sampling are included in Section 6.0.

The stream gauge installation procedures are: • At each station, using a slide hammer and temporary, 5-foot, steel fence post or similar post, drive the post to a point where it is either difficult to drive or can no longer be driven with a slide hammer. The 5-foot posts should be a minimum of 30 inches above ground surface upon completion. o Please note the stream stations may be moved if it is not practical to install them in the proposed locations due to shallow rock or if future access will be difficult. If a location is moved more than 50 feet, the Project Manager should be notified. • Using a hack saw blade, cut a small notch near the top of on of the posts that will be surveyed and used as a reference point. • Paint the top 12 inches of the fence post with high visibility, yellow paint. To make a stream level measurement use the following procedure • Tie one end of a string onto the post with the surveyed referenced point as near the reference point as practical. • Using a line level, tie off the other end of the string to the post on the opposite bank taking care to make sure that the line is level and tight. • Using a water level meter or other measuring device, measure from the string to the top of the stream surface. Record the measurement to the nearest 0.01 feet in the field logbook.

PART 2 SAMPLE COLLECTION AND ANALYSIS 2.1 Pre-sampling Activities Before initiating DPT installation, the following items will be completed: • Each location will be field checked for accessibility. • All proposed sampling locations will be staked or marked. • Utility clearance will be completed on each location. 2.2 Sampling Procedures • Groundwater samples will be collected using a DPT screen-point sampler. The screen- point groundwater sampler consists of a screen encased in a stainless steel sleeve. The screen section remains enclosed in a sheath until it is pushed out into the formation at the desired depth. • Groundwater samples will be collected approximately 5 feet below the groundwater surface and at 15 foot intervals thereafter to either probe refusal or a maximum depth of 75 feet bgs. intervals • Groundwater samples will be collected using bailers. Bailers will be gently lowered into the well to minimize disturbance of the water column. If water is encountered at sufficiently shallow depth a peristaltic pump will be used to further minimize disturbance to the water column. Samples collected using a peristaltic pump will be gathered as described below: 1. Attach and secure the flexible tubing and the polyethylene tubing to the pump. 2. The tubing will be lowered SLOWLY into the well to the appropriate depth. 3. Start the pump and set at the lowest pumping rate that will maintain a constant flow being careful to avoid surging. Precautions will be taken to avoid pump suction loss or air entrainment. 4. Reduce the pumping rate, if needed, to avoid pumping the well dry. 5. If practical, allow the well to purge before sampling. The duration of the purge will depend on aquifer conditions and will be determined by the field geologist. 6. After purging, samples will be collected directly into pre-preserved sample containers. 7. Sample containers will be filled by allowing the pump discharge to flow gently down the inside of the container with minimal turbulence. 8. Dispose of the pump tubing after sample collection. • The samples will be labeled and placed into a cooler on ice. • The samples will be logged onto the chain-of-custody form. B-1 I I I I I I I I I I I I I I I I I I I • Groundwater sampling will be documented in the field logbook for each sampling location including at a minimum, sampling ID, a descriptive site location, sample time, sample analytes, number of bottles collected, problems encountered during sample collection, and any modifications to the sampling procedures, with justification. • Field equipment will be decontaminated in accordance with the procedures provided in Appendix F. Equipment used for groundwater sampling will be decontaminated between each DPT location. Disposable equipment will be discarded after one use. After sample collection, dispose of the pump tubing/bailers and secure the well. 2.3 Groundwater Sample Analysis Groundwater samples will be collected for for the analytical parameters specified in Table 2. 2.4 Plugging and Abandonment After sampling, DPT boreholes will be plugged and abandoned using the following methods. • Any portion of the saturated zone that remains open after pulling the DPT rods will be filled with bentonite chips or pellets upon completion. Due to difficulties associated with placement of bentonite chips or pellets using a tremie, they may be placed by pouring directly into the borehole. However, they must be placed slowly and the depth to the top of the bentonite must be continuously monitored to assure that bridging does not occur. • The unsaturated portion of the boring will be completed with a 3% bentonite/cement grout. • Due to difficulties associated with placement of bentonite chips or pellets using a tremie, they may be placed by pouring directly into the borehole. However, they must be placed slowly and the depth to the top of the bentonite must be continuously monitored to assure that bridging does not occur. • To expedite DPT installation, the unsaturated portion of the borehole may be grouted at the end of the workday. • With few exceptions, (weather, request of plant personnel to leave an area) all DPT borings will be plugged and abandoned the same day they are installed. ***END OF SECTION*** B-2 I I I I I I I I I I I I I I I I I I I APPENDIX C LABORATORY METHODS AND REQUIREMENTS PART 1 GENERAL 1.0 Analytical Test Methods Sample analysis will be conducted using USEPA approved methods.

C-2 I I I I I I I I I I I I I I I I I I I 1.0 Groundwater Sampling APPENDIX D GROUNDWATER SAMPLING The objectives of the groundwater sampling procedures are: • To collect samples representative of groundwater in the formation. • To reduce the potential bias caused by the sampling equipment used to obtain the sample. Sampling procedures will follow the USEPA Region IV protocols. In general, sampling procedures for wells, where applicable, will be as follows: 2.0 1. Calibrate field equipment. 2. Decontaminate sampling equipment: a. water level indicator b. bailer C. PURGE PUMPS 3. Measure water level, record on sample collection record 4. Sound total depth of well, or refer to well construction logs. 5. Calculate well volume, if applicable. 6. Purge well with the appropriate purging device. 7. Record hydrogen ion concentration (pH), specific specific conductance, temperature, oxidation reduction potential (ORP), dissolved oxygen (DO), and turbidity following each purge volume, using Horiba U-22 and record in field notebook and on the appropriate form; 8. Collect groundwater sample. 9. Place water sample into bottles provided by laboratory. 10. Properly label sample bottles with an indelible marker, pack securely in cooler and add ice. 11. Collect quality control samples as required by the project. 12. Complete all necessary field documentation and notebook entry. Equipment Decontamination Field equipment will be decontaminated in accordance to the procedures provided in Appendix F. All equipment used for groundwater purging and sampling will be decontaminated between monitoring wells. Disposable bailers will be discarded after one use. 3.0 Water Level Measurement Groundwater levels will be measured in wells to be sampled. The water levels will be measured from the mark on the top of the well to the nearest 0.01 foot. If there is not a mark on the well casing, a mark will be placed on the casing on the side of the well casing nearest the lock hasp, or if there is not a lock hasp (i.e., flush-mount well), on the north side of the casing. Depth to water for the production wells will be measured at the appropriate opening on the sanitary well seal. Measurements will be recorded on both the field logbook and appropriate field forms. Note on the data sheets/logbook if the well is pumping at the time of measurement. If a well is not accessible, damaged, or covered, it will be documented in the field notebook and appropriate field forms. D-1 I I I I I I I I I I I I I I I I I I I 3.1 Water Level Tape Normalization When multiple water level indicators are used to collect groundwater levels, measuring tapes will be compared, or normalized, for measurement accuracy. Normalization is accomplished by first measuring the water level in a test well with the reference measuring tape, followed by the remaining tapes. The test well should have a depth to water that is average for the site. The tapes should read to within 0.02 feet of each other. Differences outside this error margin should be recorded in the field log and water levels adjusted prior to office use. The normalization procedure will be documented in the field notebook or on an appropriate field form. The brand and serial number on the water level tapes will also be documented in the field notebook with the appropriate water level measurements. 3.2 Water level Measurements Water level data will be collected using the following procedures. 1. 2. 3. 4. 5. 4.0 Remove well cap. If well is not vented and under pressure, it may be necessary to allow the water level to equilibrate. If this is necessary, a field test will be performed to determine the time required for equilibration. Lower the probe into the well until the sounding device is activated by contact with the water. Adjust sensitivity (if available), if needed. Align the measuring tape with the measuring point (MP) and read the water level to the nearest 0.01-foot. This is the depth to water (DTW) measurement that is logged into the field book. Note conditions that may effect water level in the well such as if the well is pumping or a nearby service well is in operation. Pertinent data will be documented in the field notebook with time and date. Measurement of Field Water Quality Data Prior to sampling, monitoring wells will be purged to remove stagnant water from the sampling interval. During purging, water quality parameters will be measured to assess the effectiveness of the well purge. In addition, selected field water quality parameters will be measured to assess natural attenuation at the site. The procedures for collection of the field water quality data are described in the following sections. 4.1 Groundwater Purging Stabilization Parameters During purging of the monitoring wells, dissolved oxygen, pH, ORP, specific conductance, temperature and turbidity will be measured to assess the effectiveness of the well purge.Water quality parameter measurements will be collected using a Horiba U-22 Water Quality Monitor and a flow through cell. The Horiba U-22 must be properly maintained and operated in accordance with the manufacturer's instructions. The meter will be calibrated, at a minimum, before each day's use and the calibration information will be recorded in the field notebook. The flow through cell must be properly maintained to assure that all connections remain tight. DO, ORP, and pH are affected by aeration of the samples. Therefore, when the Horiba U-22 is connected to the flow through cell, special care must be taken to assure that the connections are airtight. 0-2 I I I I I I I I I I I I I I I I I I I 4.1.1 Dissolved Oxygen Dissolved oxygen measurements will be collected with a Horiba U-22 water quality monitor. After use, the probe will be decontaminated in accordance with Appendix F. Prior to field use, the membrane of the DO meter will be inspected for air bubbles and/or holes. If air bubbles or holes exist, the membrane will be replaced. Refer to manufacturer's instructions for replacement of the membrane. In addition, the membrane will be checked for dryness. If the membrane is dry, it will be replaced and soaked in analyte-free water prior to calibration of the meter. 4.1.2 Oxidation-Reduction Potential (ORP) Groundwater ORP measurements will be collected using a Horiba U-22 water quality monitor with a flow through cell. As with all ORP measuring devices, the ORP sensor on the Horiba U- 22 can be tested for accuracy, but cannot be adjusted. The meter will be compared against a Zobell solution with known ORP concentration in accordance with the manufacturer's instructions prior to each day's field use. Before using the Horiba U-22, the monitor will be allowed to equilibrate. ORP readings should be within plus or minus 5 percent of the reference values of the Zobell solution for the instrument to be acceptable for field use. The instrument verification data will be recorded in the field notebook. After each use, the Horiba U-22 will be decontaminated in accordance with Appendix F. 4.1.3 pH Groundwater pH measurements will be collected using a Horiba U-22 water quality monitor and a flow through cell. Prior to each day's field use, the monitor will be calibrated against a reference solution in accordance with the manufacturer's instructions. The instrument calibration data will be recorded in the field notebook. After use, the probe will be decontaminated in accordance with Appendix F. Units of pH are Standard Units (SU) and will be read and recorded to the nearest 0.01 SU. 4.1.4 Specific Conductance Specific conductance measurements will be collected using a Horiba U-22 water quality monitor. Prior to each day's field use, the specific conductance sensor will be calibrated against a reference solution in accordance with the manufacturer's instructions. The instrument calibration data will be recorded in the field notebook. Specific conductance will be measured in microsiemens per centimeter (mS/cm). Results will be reported to the nearest one unit for readings below 1,000 mS/cm and to the nearest 10 units for readings above 1,000 mS/cm. 4.1.5 Temperature Groundwater temperature measurements will be collected using a Horiba U-22 water quality monitor. Temperature will be measured in degrees Centigrade. Results will be reported to the nearest tenth of one degree. Units of ORP are millivolts. 0.1 millivolt. Results will be read and recorded to the nearest (positive/negative)) D-3 I I I I I I I I I I I I I I I I I I I 4.1.6 Turbidity Turbidity measurements will be collected with a Horiba U-22 water quality monitor. Prior to each day's field use, the turbidity sensor on the Horiba U-22 monitor will be calibrated against a reference solution in accordance with the manufacturer's instructions. The turbidity values of the reference should be within 1 NTU. The instrument calibration data will be recorded in the field notebook. After use, the probe will be decontaminated in accordance with Appendix F. Turbidity readings are time sensitive due to 1) biodegradation, settling, or sorption of particles in the solution, and 2) precipitation of humic acids and minerals due to pH changes. Therefore, measurement of turbidity must not be delayed. In addition, turbidity readings may be biased by scratches, fingerprints, or dirt on the surface of sample cells. Therefore, the sampie cells will be marked to indicate their orientation. The marks will be lined for each measurement so that the light passes through the cell at the same orientation. Turbidity measurements will be recorded to the nearest 1 NTU. 4.1.7 Ferrous Iron Field measurements of dissolved ferrous iron will be made using a HACH Model 1 R-18C test kit and a HACH Model DR/2010 data logging spectrophotometer. The test kit and spectrophotometer are capable of measuring ferrous iron concentrations ranging from 0.1 mg/I to 10 mg/L. 5.0 Well Purging and Sampling -Laboratory Analysis Selected groundwater monitoring wells will be purged and sampled during the quarterly sampling event. The procedures to be used are described in the following sections. 5.1 Low-Flow Purging Techniques for Groundwater Monitoring Wells Stagnant water will be removed by purging, immediately prior to sampling. The well purge will be performed using a low-flow (minimal drawdown) method described in the Draft Recommended Procedure for Low-flow Purging and Sampling of Groundwater Monitoring Wells (Bulletin QAD023, June 16, 1999) as described below. 5.1.1 Sampling Equipment The following equipment will be required for the low-flow purging procedure. Pump Low-flow-rate electrical submersible pumps will be used for low-flow purging because (1) they are not as prone to cyclical flow/arrest as other pumps and therefore, are not as likely to mobilize fine-grained material, and (2) they are typically easier to use, thereby reducing potential operator error. The pump will be capable of operating reliably at lower flow rates (0.1 to 0.5 liters per minute). Tubing Tubing used for purging and sampling will be disposed of after each use. Raising or lowering the pump in the well must be avoided. Therefore, the same tubing will be used for both purging and sampling. Polyethylene tubing will be used to collect samples at this site. 0-4 I I I I I I I I I I I I I I I I I I I Other equipment required for this procedure is outlined below. • polyethylene sheeting; • appropriate PPE as defined in the HASP; • water level indicator accurate to 0.01 feet; • flow measurement supplies (e.g., graduated cylinder and stopwatch); • electrical generator (the generator will not be oversized for the pump); • in-line flow through cell with sampling ports for monitoring sensors for pH, turbidity, specific conductance, temperature, ORP, and DO. The flow through cell will have a by-pass for sample collection; • decontamination supplies (see Appendix F); • field notebook; • sample bottles (pre-preserved); • sample labels, chain-of-custody; • monitoring well construction data, location map, field data from last sampling event; and • approved HASP. 5.1.2 Preliminary Site Activities Where applicable, the following activities will be performed in advance of the purging and sampling to minimize turbidity of the groundwater sample. 1. Check the condition of the monitoring well. 2. Place polyethylene sheeting, as needed, in the work area to maintain a clean work area for monitoring and sampling equipment and supplies. 3. Measure and record the depth to water (to 0.01 feet) in all wells to be sampled before well purging and sampling. Care will be taken to minimize disturbance to the water column and to any particulate attached to the sides or at the bottom of the well. The total depth of a well should be measured well in advance (one to two weeks) of purging and sampling or after sampling is completed. Additionally, the depth to bottom of well may be obtained from well construction logs. Significant differences between the measured depth of the well and the well construction details should be investigated. 5.1.3 Low-flow Purging and Sampling Procedures The following section describes the procedure to be used for low-flow purging and sampling. Wells will generally be sampled in the order of least contaminated to most contaminated. 1. Attach and secure the polyethylene tubing to the pump. The tubing and safety cable will be secured to the pump using nylon stay-ties. 2. Pump, safety cable, tubing and electrical lines will be lowered SLOWLY into the well to a depth corresponding to the center of the saturated screen section of the well, or to a depth determined to be either a preferential flow path or zone where contamination is present. The pump intake will be as far above the bottom of the well, as practical, to minimize disturbance of sediment in the well. 3. Measure the water level with the pump in the well before starting the purge. Allow the water level to return to static conditions before starting the pump. 4. Start the pump at the lowest flow rate possible while continuously measuring the drawdown. The pumping rate can only be increased if there is no drawdown. Be careful to avoid surging. The pumping rate should cause little or no water level drawdown in the well (less than 0.2 ft) and the water level should stabilize. Water level measurements 0-5 I I I I I I I I 5.2 will be made as continuously as practical. Precautions will be taken to avoid pump suction loss or air entrainment. Pumping rates will be reduced. if needed, to the minimum capabilities of the pump to avoid pumping the well dry and ensure stabilization of indicator parameters. The purge water will be stored in a drum for transport to the facility wastewater treatment plant as described in Appendix G. 5. During purging, water quality parameters will be monitored including turbidity, specific conductance, pH, DO, temperature, and ORP. Readings will be collected every three to five minutes until the parameters have stabilized. Stabilization is achieved when three successive readings are within ±0.1 for pH, ±3% for specific conductance and temperature, ±10mv for redox potential (Eh), and ±10% for turbidity and DO. Minimum subsets of these parameters that can be used to determine stabilization are pH, specific specific conductance, and turbidity or DO. Turbidity and DO are typically the last parameters to stabilize. If the parameters have stabilized, but the turbidity is not less than 10 NTUs, the purge will be continued. The field geologist and the Project Manager will determine the duration of the additional purge time. 6. The samples will be labeled and placed into a cooler on ice. 7. After sample collection, dispose of the pump tubing. 8. Measure and record well total depth. 9. Secure the well. Sample Preservation I Sample bottles will be pre-preserved by the laboratory.

Cleaning procedures in this Appendix are intended for use by field personnel for field cleaning of sampling and other equipment. Deviations from these procedures must be approved by the Project Manager and documented in the field notebook. 1.1 Specifications for Cleaning Materials Specifications for standard cleaning materials referred to in this Appendix are as follows: • Soap shall be a standard brand of phosphate-free laboratory detergent such as Liquinox®. • Tap water may be used from a potable source at the plant or from a municipal treatment system. Plant process water will not be used as a decontamination water source. • Analyte free water (deionized water) is tap water that has been treated by passing through a standard deionizing resin column. Deionized water can be purchased through a local retailer. Solvents, laboratory detergent, and rinse waters used to clean equipment shall not be reused. 1.2 Handling and Containers for Cleaning Solutions Improperly handled cleaning solutions may easily become contaminated. Storage and application containers must be constructed of the proper materials to ensure their integrity. Following are acceptable materials used for containing the specified cleaning solutions: • Soap must be kept in clean plastic, metal, or glass containers until used. It will be poured directly from the container during use. • Solvent must be stored in the unopened original containers until used. They may be applied using squeeze bottles. • Tap water may be kept in clean tanks, hand pressure sprayers, squeeze bottles, or applied directly from a hose. • Analyte free (deionized) water must be stored in the original container until used, or in clean glass, stainless steel, or plastic containers that can be closed before use. It can be applied from plastic squeeze bottles. Note: Hand pump sprayers generally are not acceptable storage or application containers for the above materials (with the exception of tap water). This also applies to stainless steel sprayers. All hand pump sprayers have internal oil coated gaskets and black rubber seals that may contaminate the solutions. F-1 I I I I I I I I I I I I I I I I I I I 1.3 Disposal of Solvent Cleaning Solutions Procedures for the safe handling and disposition of investigation derived waste (IDW), including used wash water, rinse water, and spent solvents are included in Appendix G. 1.4 Safety Procedures for Field Cleaning Operations Some of the materials used to implement the cleaning procedures outlined in this Appendix can be harmful if used improperly. All field personnel will exercise caution and all applicable safety procedures will be followed when handling cleaning materials. At a minimum, the following precautions will be taken in the field during these cleaning operations: • Safety glasses with splash shields or goggles, and nitrite gloves will be worn during all cleaning operations. • Solvent rinsing operations will be conducted in the open (never in a closed room). • No eating, smoking, drinking, chewing, or any hand to mouth contact will be permitted during cleaning operations. 1.5 Handling of Cleaned Equipment After field cleaning, only personnel wearing clean gloves to prevent re-contamination will handle equipment. In addition, the equipment will be moved away (preferably upwind) from the cleaning area to prevent re-contamination. If the equipment is not to be immediately re-used it will be covered with plastic sheeting or wrapped in aluminum foil to prevent re-contamination. The area where the equipment is kept before re-use must be free of contaminants. 2.0 Specifications for Decontamination Pads Decontamination pads constructed for field cleaning of sampling and drilling equipment will meet the following minimum specifications: • The pad will be constructed in an area known or believed to be free of surface contamination. • To the maximum practical extent, the pad will not leak. • If possible, the pad will be constructed on a flat, sloped, paved surface to facilitate removal of wastewater. This may be accomplished by either constructing the pad with one corner lower than the rest, or by creating a sump or pit in one corner or along one side. Any sump or pit will also be lined. • Sawhorses or racks constructed to hold equipment while cleaning will be high enough above ground to prevent equipment from being splashed. • Water will be removed from the decontamination pad frequently. • A temporary pad will be lined with a water impermeable, seamless, material. This material will be either easily replaced (disposable) or repairable. At the completion of site activities, the decontamination pad will be deactivated. The pit or sump will be backfilled, if applicable, with an appropriate material designated by the site manager, but only after all waste/rinse water have been pumped into containers for disposal. No solvent rinsates will be placed in the pit. Solvent rinsates should be collected in separate containers for proper disposal. F-2 I I I I I I I I I I I I I I I I I I I 3.0 Field Equipment Cleaning Procedures The following procedures are to be utilized when equipment must be cleaned in the field. • Field Cleaning Procedure for the Collection of Trace Organic and Inorganic Compounds 1. Clean with tap water and soap using a brush if necessary to remove particulate matter and surface films. Equipment may be steam cleaned (soap and high pressure hot water) as an alternative to brushing. Sampling equipment that is steam cleaned will be placed on racks or saw horses at least two feet above the floor of the decontamination pad. Special care will be taken when steam cleaning PVC or plastic items. 2. Rinse thoroughly with tap water. 3. Rinse thoroughly with analyte free water. 4. Rinse thoroughly with solvent (isopropyl alcohol). This step is required only for wells in areas where known free phase liquids have been encountered. The decision not to use the solvent rinse will be approved by the Project Manager and documented in a field notebook. 5. Rinse thoroughly with analyte free water. Allow equipment to dry completely before use. 6. Remove the equipment from the decontamination area and wrap with aluminum foil. • Water Level Meters or Tapes 1. Wash with soap and tap water; 2. Rinse with tap water; and 3. Rinse with analyte free water. • If the water level meter has contacted a free phase product. the procedures in Section F3.1 will be followed. 3.3 Pumps The pumps will be cleaned before use and between each monitoring well. The following procedure is required: CAUTION -Make sure the electrical receptacle is in a well-drained area. 1. Using a steam cleaner, clean the exterior of the pump, electrical cord and discharge hose with soap and tap water. Do not wet the electrical plug. 2. Fill and appropriately sized container with soap and tap water. Place the pump in the container and pump until soapy water can be seen flowing from the discharge hose. 3. Fill and appropriately sized container with tap water. Place the pump in the container and pump until clear water can be seen flowing from the discharge hose. 4. Fill and appropriately sized container with analyte free water. Place the pump in the container and pump a sufficient volume to purge the tap water from the system. 5. Place the equipment in a clean plastic bag. F-3 I I I I I I I I I I I I I I I I I I I 3.4 Downhole Drilling Equipment These procedures are to be used for drilling activities involving the collection of soil and groundwater samples for trace organic and inorganic constituent analyses, and for the construction of monitoring wells to be used for the collection of groundwater samples for trace organic and inorganic constituent analyses. Cleaning and decontamination of all · equipment will occur at a designated area (decontamination pad) on the site. The decontamination pad will meet the specifications of Section .2.0. Tap water (potable) brought on the site for drilling and cleaning purposes will be contained in a pre-cleaned tank of sufficient size so that drilling activities can proceed without having to stop and obtain additional water. A steam cleaner and/or high pressure hot water washer capable of generating a pressure of at least 2500 PSI and producing hot water and/or steam (200'F plus), with a soap compartment, will be used. 3.4.1 Preliminary Cleaning and Inspection The drill rig will be clean before being brought to the site to minimize the potential for cross- contamination. Further, the drill rig itself should not serve as a source of contaminants. In addition, associated drilling and decontamination equipment, well construction materials, and equipment handling procedures will meet these minimum specified criteria: • All downhole drilling, and sampling equipment should be sandblasted before use if painted, and/or there is a buildup of rust, hard or caked matter, etc., that cannot be removed by steam cleaning (soap and high pressure hot water), or wire brushing. Sandblasting should be performed before arrival on site, or well away from the decontamination pad and areas to be sampled. • Any portion of the drill rig that is over the borehole {kelly bar or mast, drilling platform, hoist or chain pulldowns, spindles, cathead, etc.) will be steam cleaned (soap and high pressure hot water) and wire brushed (as needed) to remove rust, soil, and other material which may have come from other hazardous waste sites before being brought on site. • Printing and/or writing on well casing, tremie tubing, etc. will be removed before use. Emery cloth or sandpaper can be used to remove the printing and/or writing. Most well material suppliers can supply materials without the printing and/or writing if specified when ordered. • The drill rig and other equipment associated with the drilling and sampling activities will be inspected to insure that all oils, greases, hydraulic fluids, etc., have been removed, and all seals and gaskets are intact with no fluid leaks. • PVC or plastic materials such as tremie tubes will be inspected. Items that cannot be cleaned are not acceptable and will be discarded. F-4 I I I I I I I I I I I I I I I I I I I 3.4.2 Drill Rig Field Cleaning Procedure Any portion of the drill rig, backhoe. etc., that is over the borehole (kelly bar or mast, backhoe buckets, drilling platform, hoist or chain pulldowns, spindles, cathead, etc.) will be steam cleaned (soap and high pressure hot water) between boreholes. 3.4.3 Field Cleaning Procedure for Drilling Equipment The following is the standard procedure for field cleaning augers, drill stems, rods, tools, and associated equipment. This procedure does not apply to well casings, well screens. or split- spoon samplers used to obtain samples for chemical analyses, which will be cleaned as outlined in Section F.3.1. 1. Clean with tap water and soap, using a brush if necessary, to remove particulate matter and surface films. Steam cleaning {high-pressure hot water with soap) may be necessary to remove matter that is difficult to remove with the brush. Drilling equipment that is steam cleaned will be placed on racks or saw horses at least 2 feet above the floor of the decontamination pad. Hollow-stem augers drill rods, etc., that are hollow or have holes that transmit water or drilling fluids, will be cleaned on the inside. 2. Rinse thoroughly with tap water. 3. Remove from the decontamination pad and cover and store in a clean portion of the site. F-5 I I I I I I I I I I I I I I I I I I I APPENDIX G INVESTIGATION DERIVED WASTE (IDW) 1.0 Types of IDW Materials that may become IDW are: • Personnel protective equipment (PPE) --This includes disposable coveralls, gloves, booties, respirator canisters, splash suits, etc; • Disposable equipment --This includes plastic ground and equipment covers, aluminum foil, conduit pipe, tubing, broken or unused sample containers, sample container boxes, tape, etc; • Soil cuttings from drilling or hand augering; • Ground water obtained through well development or well purging; • Cleaning fluids and washwater; and • Packing and shipping materials. 2.0 Management of Non-Hazardous IDW Non-hazardous IDW in the form of trash and debris will be disposed onsite in the facility dumpsters. Soils generated during monitoring well installation will be drummed and properly labeled pending disposal. A composite sample of the drums will be collected at the completion of the installations for waste characterization. Storage of the drums will be coordinated with facility personnel. Groundwater generated during well development, purging and sampling will be collected in drums and processed through the plant wastewater treatment system at the completion of each day's activities. The discharge point will be established with plant personnel at the beginning of each workday, if possible. The quantity of water placed into the system will be entered into the field notebook. 3.0 Management of Hazardous IDW No hazardous IDW is expected to be generated. However, if a waste is determined to be hazardous waste, it may be stored on the site for a maximum of 90 days before it must be manifested and shipped to a permitted treatment or disposal facility. Generation of hazardous IDW must be anticipated, if possible, to permit arrangements for proper containerization, labeling, transportation, and disposal/treatment in accordance with EPA regulations.
