1.0 INTRODUCTION

This document describes the Initial Testing Program (ITP) to beundertaken for the purpose of testing and documenting the performanceof the Air Stripper System recently installed at the Ponderosa Well, locatedin Vega Alta, Puerto Rico. This Initial Testing Program Plan has beendeveloped to present the operation plans, sampling procedures, andquality assurance measures that will be used during the ITP. Theobjective of the ITP is to confirm that the ground water treatment systemat the former Puerto Rico Aqueduct and Sewer Authority (PRASA)production well reduces Volatile Organic Compounds (VOC) in thetreated effluent to the levels specified in the Order and provided inTable 1. The treated water will be discharged to Honda Creek during thisthree week test period. The ITP Plan also includes health and safetyissues, a listing of the personnel to be involved in the FTP, and adescription of the FTP Report to be prepared at the conclusion of the FTP.The FTP field activities are expected to be completed in three weeks.

The FTP Program will be performed by Environmental ResourcesManagement, Inc. (ERM), with the Construction Contractor, JaferConstruction, available on call in the event any mechanical or electricaldifficulties arise.

1.1 System Description

For a complete description of the Ponderosa Air Stripper System, thereader is referred to the Plans and Specifications contained in the FinalRemedial Design documents approved by the US EPA, dated 17 January1992. A brief description of the system is provided here for convenience:

The Ponderosa Air Stripper System consists of a submersible well pump,chemical pretreatment to reduce scaling, a packed air stripper column, an ^air supply blower, and a stripper bottoms pump. All equipment and opiping are housed in an insulated steel building for purposes of site ~'"5

security and noise attenuation. The upper portion of the stripper column ^protrudes through the roof of this building. The design capacity of thesystem is 600 gpm. The treated water can be discharged to either HondaCreek or to the water distribution system of the Puerto Rico Aqueduct andSewer Authority (PRASA). Provisions are included for the future

3.0 SAMPLING AND ANALYSIS

The sampling and analysis tasks proposed to accomplish the ITPOperating Plan are as follows:• The Site Engineer will collect influent and effluent samples from the

Ponderosa air stripper at varying flow rates (50%, 75%, and 100%)over a three week sampling period;

• A qualified laboratory will perform and report the sample analyses;• ERM will review and evaluate the data; and• ERM will prepare an ITP Report.

3.1 Influent/Effluent Sampling Procedures

The duration of the FTP will be completed within three weeks unless theanalytical results of the samples collected at the 50%, 75%, or 100% feedrates indicate that the system effluent does not meet the effluent limitationset forth in Table 1. The Site Engineer will be available to trouble-shootany problems which may arise in the field during operations. Table 3summarizes the number of samples to be collected at the various flowrates and other pertinent sampling and analysis information.

The ITP operations will commence with a system startup at 50% of thedesign water feed rate (300 gpm). Samples will be collected by the SiteEngineer from both the pre (influent) and post (effluent) treatment spigotson a daily basis for three consecutive days and analyzed for the TargetCompound List (TCL) Volatile Organic Compounds (VOCs) whichincludes the constituents listed in Table 1. Samples will be collected justprior to express shipping pickup and air-expressed to the laboratory on a24-hour turnaround time (TAT) basis.

If the analytical results from the 50% feed rate show that the specificconstituent effluent limitations presented in Table 1 have not beenexceeded, the feed rate will be increased to 75% of the design (450 gpm).

A Q . I n f l u e n t and effluent samples will be collected on a daily basis just before-* express shipping pickup for another three days at the 75% feed rate.

Samples will be collected for TCL VOCs and submitted to the laboratoryon a 24-hour TAT.

Based upon the results of the 75% feed rate samples, the rate will beincreased to 100% of the design flow (600 gpm). Daily sampling of theinfluent and effluent sample locations will be performed for another threedays to ensure that the required discharge limitations are not exceeded.

Samples collected at 100% of the feed rate for the initial three day periodwill be submitted to the laboratory on a 24-hour TAT. Sampling will bereduced to every other day for the remaining 12 days of the Program andsubmitted to the laboratory on a regular TAT.

In order to procure representative samples from the influent and effluentlocations, the sample taps will be purged for one minute prior to samplecollection to flush the sample port After the sample tap is purged, theflow rate will be decreased to a low velocity so that samples can becollected without introducing air into the sample. Sample vials will becarefully filled to ensure that no air bubbles remain when capped. Theinfluent sample will be collected first, followed by the effluent sample.

To limit the potential for cross-contamination between samples, samplingpersonnel will wear clean, disposable surgical gloves for the collection ofeach sample. The samples will be placed in the laboratory-suppliedsample vials which will be preserved in the field with HC1, after samplecollection, in accordance with USEPA Region II CERCLA qualityassurance guidelines. The samples will then be labeled, logged on aChain-of-Custody Form, and placed in a cooler at 4°C for daily shipmentto Lancaster Laboratories, Inc., located in Lancaster, Pennsylvania.

Analytical results will be facsimiled to the ERM Sampling Coordinator inExton, Pennsylvania within two days of the sampling. The preliminaryresults will be reviewed and transmitted to the Site Engineer via afacsimile and/or telephone the same day that the results are received. TheSite Engineer will continue the ITP, as specified in Section 2, based uponthe expedited analytical results.

QA/QC Samples

Travel blanks will be submitted to the laboratory at a frequency of oneaqueous travel blank per shipment. A travel blank for ground waterconsists of sample bottles filled with laboratory demonstrated analy te-freewater. The purpose of collecting a quality control travel blank is to checkfor cross-contamination within sample shipment containers and forchanges occurring during shipping and the laboratory storage process.Travel blanks will be handled, transported, and analyzed in the samefashion as the regular samples, except that the travel blanks are notopened in the field. Travel blanks are designed to accompany the samplesto the laboratory and to be analyzed for TCL VOCs.

Blind duplicate samples will be collected to allow determination ofanalytical precision for the 50%, 75%, and 100% design capacity. Oneduplicate sample will be collected for every 20 samples. The duplicate

10233 2THE ERM CROUP 8 THEWESTCOMPAVY-EC334.00JI-10/'22/93

samples will be collected from the effluent of the treatment system andsubmitted to the laboratory for TCL VOC analysis.

Matrix spike/matrix spike duplicates (MS/MSD) will be submitted at afrequency of one per twenty samples or one in 14 days, whichever comesfirst. Triplicate sample volume will be collected from the influent samplelocation for the MS/MSD samples. The Site Engineer will designate theMS/MSD sample for quality control proposes and indicate thisinformation on the chain-of-custody sheet.

Samples collected during the various well water feed rates and submittedfor TCL VOCs will require a CLP data package to ensure accuracy andprecision of the sample results and to provide documentation for usabilityand qualification of the data.

3.3 Sample Custody

The primary objective of sample custody procedures is to create anaccurate written record which can be used to trace the possession andhandling of all samples from the moment of their collection, throughanalysis, until their final disposition.

Immediately after sample collection, sample bottles will be sealed inindividual plastic bags. Samples will then be placed immediately into aninsulated cooler for shipment to the laboratory. Chain-of-Custody recordswill accompany the samples inside the cooler for shipment to thelaboratory. Each cooler will contain sufficient ice and/or ice packs toensure that the temperature is properly maintained at 4°C and will bepacked in a manner to prevent damage to sample containers. Custody

; seals will be placed on the sample coolers to ensure sample integrityduring shipping. Samples will be shipped daily to the laboratory using anovernight delivery service.

3.4 Health and Safety Plan

A Health and Safety Plan (HASP), dated 11 May 1989, was included as anattachment to the approved Sampling, Analysis, and Monitoring Plan

1 C' 1 Q i o (SAMp) dated 19 February 1990 for the site. This HASP was developed as1 J «. o J u guidance for the level of protection required for site personnel conducting

field investigations at the site and will be used as part of the ITP. TheHASP is site-specific and is based on data collected during previousinvestigations and knowledge of the site. The HASP specifies the action

f, — N. levels that dictate the required level of safety apparel and workingprocedures appropriate for particular site conditions. Occupational Safetyand Health Administration (OSHA) 1910.120 regulations were followed in

PROCEDURE OUTLINEMECHANICAL CHECKOUT &

SYSTEM STARTUP PROCEDURESPONDEROSA AIR STRIPPERVEGA ALTA REMEDIATION

22 October 1993

The following procedures will be used to perform the mechanicalcheckout and the startup of the Air Stripper System at the PonderosaWell in Vega Alta. The Mechanical Checkout (Part 1) will be performedjust prior to the start of the Initial Testing Program (ITP) to ensure thatall components of the System are in proper working order for the ITP.The System Startup Procedure (Part 2) will be used during theMechanical Checkout as well as during the operations phase of the ITP.

1 MECHANICAL CHECKOUTThe purpose of the Mechanical Checkout is to check the operation ofthe mechanical equipment, to confirm the calibration of the flow meter,and to verify that the shutdown interlocks and alarms work. Use thefollowing step-by step instructions for this test.1.1 Start the air blower by turning the Hand-Off-Auto (HOA) switch.

located on the face of the motor control center (MCC), to theHand position. There are two switches for each of the 480-voltmotors, an HOA switch on the MCC, and an Off-Auto Switch on theface of the Control Panel. The motor will always run in the Handposition of the MCC HOA switch, will not run in the Off position,and will be controlled by the Control Panel switch in the Autoposition of the MCC HOA Switch. Additionally, when the MCC HOASwitch is in the Auto position, the Off-Auto Switch on the ControlPanel will not permit the motor to run in the Off position, and willpermit the PLC program to decide if the motor runs in the Autoposition.Observe proper operation of Blower B-l and pressure gage PI-47on blower discharge. PI-47 should read about 1 inch WC with anew, clean packing bed in the Stripper. Allow the blower to runfor a minimum of 10 minutes, then stop it by turning the B-l MCCHOA switch to Off.

102319Appendix A - 1

1.2 Open the following valves:V-l, V-2, V-3, V-4, V-8, and V-10

1.3 Close the following valves:V-5, V-6, V-7. V-ll. and V-l 2The system valves are now properly set up to charge the stripperwith well water and to recirculate water from the bottom of thestripper to the top of the stripper with no net water flow throughthe system. During this initial filling of the system, the calibrationof Well Water Flow Meter FIT-39 will be checked for accuracy.This will be accomplished by manually setting Well Water FlowValve FV-39 to 40% open, starting Well Pump P-13. observing thetime it takes to raise the level in the sump three feet, andcomparing the calculated flowrate value to the observed flowratevalue indicated on Well Water Flow Indicator FI-39. Details of thisprocedure follow:

1.4 Place the MCC HOA Switch in Auto, and the Off-Auto SelectorSwitches on the Control Panel to Auto for Well Pump P-13 andBlower B-l. Place both switches for Stripper Effluent Pump P-5 inOff. to k^ep this pump from running.

1.5 Turn Valve FV-39 Manual-Auto Selector Switch to Manual, andregulate the output on the adjacent FV-39 Positioner Knob to 40%open.

1.6 Similarly, set Sump Level Control Valve LV-51 to 40% open, withits Manual-Auto Selector Switch in Manual.

1 . 7 Manually Start Chemical Agitator AG- 1 . Confirm that it has started .1.8 Set Well Pump P-13 Shutdown Delay to 2 minutes, by turning the

Timer Setting Knob and observing the proper reading on the WellPump Delay Timer Indicator.

1.9 Similarly set the Blower B-l Shutdown Delay to 5 minutes, usingthe Timer Setting Knob and the Delay Timer Indicator for theblower.

1.10 Set Chemical Feed Pump Speed Indicator to 30% by adjusting theChemical Pump Speed Setting Knob and observing the properreading on the Speed Indicator. Turn Chemical Pump wall switchto On and its variable frequency drive fVFD) to Auto. Hiis will linkthe rate of chemical addition to the well water flow rate.

Appendix A - 2

1.11 Press the Yellow PLC Alarm/Reset Light to reset the PLC. Thisstep will start Well Pump P-13, Metering Pump P-9, and Blower B-1. As the system fills with well water, observe the water level inthe level glass in the sump of the Stripper, and time its rate of risefrom a "zero" point near the bottom of the glass to a point 3'-0"higher. At the same time, observe the reading, in gallons perminute (gpm) on Well Water Flow Indicator FI-39. Record bothobservations in the log. The 3"-0" rise in level is equivalent to 634gallons. Calculate the average gpm by dividing the 634 gallonsvolume by the observed filling time, in minutes. This calculatedrate should be within 5 percent of the reading observed on FI-39.

1.12 Confirm that Well Pump P-13 stops when the water level reacheshigh-high level switch (LSHH-50) in the Stripper Sump.

1.13 After confirming that the blower was running during this initialfilling Step 1.11, open V-5 and allow the treated water in thesump to drain by gravity to Honda Creek. When the sump level hasstabilized, close V-5.

1.14 Place both the MCC HOA Switch and the Off-Auto Selector Switch/*"""•*•• for Stripper Effluent Pump P-5 in Auto. Restart the System by

pressing the yellow PLC Alarm/Reset Light, starting P-13, P-9, andBlower B-l.

1.15 Confirm that Stripper Bottoms Pump P-5 starts when the sumpwater level rises above high level switch LSH-49. Water will berecirculating from the bottom of the stripper to the water inlet.with Blower B- 1 running at this time, ensuring that the water isbeing stripped of volatile organic compounds (VOCs) by the airfrom Blower B-l.

1.16 Confirm that Metering Pump P-9 starts with Well Pump P-13 andstops when P-13 stops.

1.17 Stop Well Pump P-13 when the sump level reaches approximately24. inches. Confirm that Blower B-l stops 5 minutes later.

1.18 Approximately 3 minutes after F-13 has stopped, but 2 minutesbefore Blower B-l is set to stop, slowly open Manual Valve V-5,permitting the stripped water to leave the system and dischargeto Honda Creek. Manually regulate the % open of LV-51, ifnecessary, by using the valve controls on the Control Panel, if it isdetected that the discharge rate is too low or too high. Observethat P-5 stops at low sump level LSL-43 set point. Prevent BlowerTimer from timing out before this test is complete by increasingBlower Tinier Delay setting, if necessary.

2 SYSTEM STARTUPThis test Is to confirm that the System performs properly during a

' normal startup of the System, as will be performed normally by theSystem Operator. This same procedure will be used during thestartup and normal operation portion of the FTP. Use thefollowing step-by-step instructions for this portion of the test.

2.1 Place all MCC HOA switches to Auto and all Control Panel MotorOff-Auto Selector Switches to Off.

2.2 Open the following valves:V-l. V-2, V-3, V-5. V-8, and V-10.

2.3 Close the following valves:V-4, V-6, V-7, V-ll, and V-12.The valve positions listed in 2.2 and 2.3 will result in discharge ofthe treated water to Honda Creek.

2.4 Set Well Water Flow Controller FIC-39 to 300 gpm. To change the_^ setpoint, if it is presently set at a flow value different than 300

gpm, use the following procedure:2.4.1 Push "SEL" key until SV (setpoint variable) is indicated on

the display.2.4.2 Push "DATA" key once.2.4.3 Use the A key to select which of the three digits are to be

changed (i.e., front of panel - left to right A A A).A A A 100 digit keyA A A 10 digit keyA A A i digit key

The appropriate digit will flash when selected.The A key for each position increases the value for thatposition, the v key decreases the value for each of the A

digit positions.2.4.4 Repeat as necessary until desired set point value is

displayed.2.4.5 Push "ENT" (enter) key to store the new set point value.

102322Appendix A - 4

2.5 Set Stripper Sump Level Controller LIC-51 to 18 inches, which isapproximately the mid-point of the level glass mounted on thestripper sump, using the same procedure outlined above in Part2.4 for FIC-39. At this time, the Valve Manual-Auto SelectorSwitches for both FV-39 and LV-51 should remain in Manualposition, with the output to each valve set at 40% open.

2.6 Set Well Pump P-13 Shutdown Delay to 2 minutes, by turning theTimer Setting Knob and observing the proper reading on the WellPump Delay Timer Indicator.

2.7 Similarly set the Blower B-l Shutdown Delay to 5 minutes, usingthe Timer Setting Knob and the Delay Timer Indicator for theblower.

2.8 Place the PLC Selector Switch to Auto position. Confirm that theyellow light goes out.

2.9 Set Chemical Feed Pump Speed Indicator to 30% by adjusting theChemical Pump Speed Setting Knob and observing the properreading on the Speed Indicator. Set the variable displacement dialon the pump to 10. Turn Chemical Pump wall switch to On and itsvariable frequency drive (VFD) to Auto. This will link the rate ofchemical addition to the well water flow rate.

2.10 Manually Start Chemical Agitator AG-1.2.11 Place the Off-Auto Switches on the Control Panel in Auto for P-13,

P-5. and B-l.2.12 Press the Yellow PLC Alarm/Reset Light to reset the PLC. This

step will start Well Pump P-13, Metering Pump P-9, and Blower B-1. As the system fills with well water, observe the water levelincrease in the level glass in the sump of the Stripper. StripperBottoms Pump P-5 will start at the LSH-49 set point. Read theactual water level, in inches, on the process variable display of LIC-51 (red indicator), and adjust the water level manually, using theLV-51 Positioner Knob, until the Process Variable (red indicator)is equal to the Set Point (green indicator). At this point, quicklytransfer the LV-51 Manual-Auto Selector Switch from Manual toAuto, for a "bumpless transfer".

2.13 Read the actual flow, in gpm, on the process variable display ofFIC-39. Adjust the actual flow, using the FV-39 Positioner Knob,until the Process Variable is equal to the Set Point (initially 300gpm). At this point, quickly transfer the FV-39 Manual-AutoSelector Switch from Manual to Auto, for a "bumpless transfer".

Appendix A - 5 182323

2.14 At this point, the System is on-line, processing 300 gpm of wellwater. Check all equipment for proper operation, examining forunusual noises, vibrations, leaks, etc. Confirm that the feedflowrate and level control are maintaining their chosen setpoints.Confirm that Metering Pump P-9 is dosing chemical reagent at aspeed of 15 %. Allow the system to run for a minimum of 1/2hour during this system check.

2.15 To change the well water flow rate, use the following procedure:2.15.1 Change FV-39 Manual-Auto Selector Switch from Auto to

Manual. This will retain the well water flow rate at itsprevious rate.

2.15.2 Push "SEL" key until SV (setpoint variable) is indicated onthe display.

2.15.3 Push "DATA" key once.2.15.4 Use the A key to select which of the three digits are to be

2.16 Confirm that Metering Pump P-9 speed has changed in proportionto the well water flow rate.

2.17 During the initial startup and checkout of the System, but notnecessarily on subsequent startups, confirm that the followingactions occur:2.17.1 If P-9 stops. Well Pump P-13 stops after time delay of 2

minutes. (P-9 failure can be simulated by turning the P-9switch to Off)

2.17.2 PSL-22 stops Well Pump P-13 on low pressure. (Can besimulated by stopping Blower B-1 (putting B-1 MCC HOA inOff), or by disconnecting leads on PSL-22)

2.17.3 Demonstrate proper operation of PCV-8 by closing V-10and observing that Sump level is maintained at its set pointduring a well water feed rate of 600 gpm. Confirm that thepressure reading on PI-15 during this operation is 110psig.

2.17 A After treated water is being accepted by The Puerto RicoAqueduct and Sewer Authority (PRASA), confirm that FI-40indicates the identical flow rate as Well Water Flow MeterFI-39, and that FQI-40 accurately shows the accumulativetotal gallons to date.

2.17.5 Measure and record the current draw per phase for WellPump P-13, Blower B-l, and Stripper Bottoms Pump P-5.These values should be approximately 50. 10, and 80 amps,respectively.

2.18 To shutdown the entire system at any time, turn either the MCCHOA or the Off-Auto Switch for Well Pump P-13 to "Off andobserve that all motors stop after the appropriate time delays.
