These products and materials shall be labeled, listed on an inventory, and stored in the AS portion of the equipment building.

PART 3 EXECUTION 3.01 GENERAL CONDITIONS

PGW anticipates operation parameters will vary over a wide range during operation. The Pilot Test has determined that vapor-phase contaminant concentrations will be extremely high during initial startup and early operation (see reference). Concentrations are expected to decrease with extended operation


10800-4

and stabilize at significantly lower levels. The groundwater flux through the treatment zone is low (0.072 ft/day). Consequently, once the high vapor-phase concentrations are removed from the AS/SVE zone, recharge of contamination is expected to decrease.

PGW anticipates that initial gas treatment shall require a Thermal Oxidizer for destruction of VOCs. The Contractor may propose alternative methods for PGW consideration. As high VOC concentrations decrease with extended operation other methods should become more cost effective (i.e., Catalytic Oxidation and Granulated Activated Carbon Absorption).

3.02 INITIAL SYSTEM STARTUP AND TESTING A. For health and safety and environmental protection reasons, initial systems

startup and operation shall begin with a stepped-rate test of the SVE system. The purpose of the stepped-rate test is to establish individual SVE well flow rates and vapor quality. The following is a general outline of the testing. The Contractor shall present a more detailed procedure in the O&M Plan. The procedures outlined below may require modification based on actual measure parameters and safety criteria in accordance with the end points and parameters of the approved O&M Plan.

B. Qualified Contractor and AS/SVE mechanical system and thermal oxidizer supplier personnel shall be present for initial startup and testing. If operational parameters become a concern at any time during the test, personnel shall shut the systems down for evaluation, adjustment, and/or repair.

C. An LEL/Methane/O2 meter and a PID shall be used to measure extracted gas levels and to compare and correlate with the internal LEL meter in the Thermal Oxidizer unit and laboratory analyses.

D. A barometer and thermometer shall be used to record pressures and temperatures at regular intervals during initial system startup and testing.

E. The thermal oxidizer shall be started and adjusted with ambient air and natural gas. Operational parameters shall be recorded.

F. The SVE well closest to the AS/SVE equipment building shall be operated and the vacuum at the well head adjusted to 10 i.w.

G. Following system stabilization, all applicable parameters shall be measured and recorded (i.e., vacuums, flows, temperatures, quality with LEL/Methane and PID, pressures, etc.). Vacuums at SVE wells on either side of the operated well shall be measured and recorded.

H. The vacuum shall be stepped-up in 10 i.w. increments and the parameters measured and recorded until the flow exceeds the design flow of 110 scfm or the wellhead vacuum exceeds 40 i.w. The vacuum may be increased up to 60 i.w. at some SVE wells if required based on test conditions.

I. The AS wells associated with the each SVE well shall be tested to check for proper operation. During the last step of SVE operation the AS wells associated with the SVE well being tested shall be opened and the AS


10800-5

compressor started and adjusted to the design pressure. The manifold flow and pressures and individual well head pressures shall be measured and results recorded. The AS wells shall only be operated for a limited time period to allow measurements to be made.

J. During testing, the flow to the TO unit shall be evaluated and dilution adjusted to prevent the concentration from exceeding 80% of the LEL.

K. Once the stepped-rate test is complete at a given well, turn off the blower and allow the system to stabilize back to a level where initial background conditions are observed (i.e., zero vacuum measured at the test well).

L. Repeat the stepped-rate testing at next closest SVE well beginning with Step D above.

M. Following the testing of all 9 SVE wells, the collected data shall be reviewed by field personnel with the Engineer and three SVE wells chosen for air sampling. The system shall be operated and a sample collected in a Tedlar bag for VOC analyses via TO-3 from the sample port of the chosen SVE well manifold legs.

N. Initial testing data shall be evaluated to establish routine operation parameters.

O. As part of construction phase, prior to initiating unattended operation of the system, all components of the system are required to be operated together (synchronously) for a continuous attended period of 5-working days, 8-hours per day. After the successful completion of the abovementioned operation, attended synchronous operation shall continue for all components of the system for a continuous period of 48 hours.

3.03 ROUTINE OPERATION A. Routine operation shall begin following evaluation of the initial startup testing

outlined in Part 3.02 above.

B. Routine operation shall include operation of one or more SVE wells and associated AS wells. Well operating frequencies and durations shall vary based on initial testing results, but at a minimum each AS/SVE well group shall be operated for 2.5 hours each day.

C. The PLC in the AS/SVE Control Panel shall control timers for AS and SVE wells (on/off solenoid valves) at preset intervals. Intervals shall be adjusted to optimize the system.

D. Well groups shall be operated to minimize natural gas usage in the thermal oxidizer for treatment of the extracted vapor prior to air discharge.

E. As approved by the Engineer, extracted vapors shall be sampled and submitted for laboratory analyses. At a minimum, the three well configurations showing the highest LEL/methane and PID reading shall be sampled monthly for volatile organic analyses by EPA Method TO-15 for the first three months of operation. For comparison purposes, duplicate samples shall be collected and submitted for analysis using EPA Method TO-3 for


10800-6

benzene, toluene ethylbenzene, and xylenes (BTEX) as well as diesel range Total Petroleum Hydrocarbons (THP) and gasoline range TPH analyses. Additional sampling subsequent to the first three months shall be as determined by the Engineer and PGW.

F. At a minimum, routine O&M shall require two visits per week for the first year of operation and maintenance with each visit lasting a minimum of 4-hours on-site..

G. All applicable parameters shall be measured and recorded (i.e., vacuums, flows, temperatures, quality with LEL/Methane and PID, pressures, etc.). Vacuums at SVE wells on either side of the operated well shall be measured and recorded.

H. Operation of the AS/SVE groups shall be staggered during the visits to assure measurement of applicable parameters for all groups at least three times.

I. Any problems or concerns identified by the Contractor shall be immediately communicated with the Engineer or PGW.

3.04 ROUTINE MAINTENANCE A. The Contractor shall perform all routine maintenance work at the frequencies

identified herein and in the approved Operation and Maintenance Plan for the system.

B The Contractor shall perform all scheduled maintenance and minor work needed to keep all equipment in operational condition.

C The Contractor shall respond to emergency and alarm conditions as part of routine maintenance.

D Custodial Services shall be provided as-needed. The plant equipment and general premises shall be maintained neat and clean.

2.0 WELL INSTALLATION

From September 24 through September 26, 2014 and on October 6, 2014, two (2) AS wells (AS-4S and AS-10S), two (2) SVE wells (SVE-4S and SVE-10S, one (1) EAB injection well (EAB-10S) and 10 vapor monitoring points (MP-4S-1 through MP-4S-5 and MP-10S-1 through MP-10S-5) were installed for the pilot testing activities at monitoring wells MW-4S and MW-10S. The AS wells, AS-4S and AS-10S, were installed to depths of 35 feet and 32 feet, respectively. The SVE wells SVE-4S and SVE-10S were installed to a depth of 22 feet. The vapor monitoring points were installed at varying depths such that the bottom of each well screen was at the top of the water table to a depth of approximately 25 feet. The locations of all the test wells are presented on Figure 3.

Prior to beginning drilling activities, both public and private utility mark-outs were completed. Additionally, before drilling, each location was hand cleared to a depth of approximately five (5) feet below surface grade (bsg) to ensure that no subsurface utilities or other obstructions were present. It was noted that during hand-clearing activities, subsurface piping was uncovered. It was determined that the piping was not in service where uncovered and was avoided during well installation. The wells were installed using hallow stem auger drilling methodology. The AS wells and SVE wells were constructed with 5-feet of 2-inch 0.020-slot schedule 40 polyvinyl chloride (PVC) screen followed by solid PVC riser to grade. The EAB well was constructed with 15-feet of 2-inch 0.020-slot schedule 40 PVC screen followed by solid PVC riser to grade. The monitoring points were constructed with 10-feet of 1-inch 0.020-slot schedule 40 PVC screen followed by solid PVC riser to grade. A No. 1 silica sand pack was placed to approximately two feet above the well screen, followed by a 2-foot bentonite seal and a bentonite-cement grout mixture to the surface. The wells were completed as flush-mounts, and a watertight, flush-mount manhole was placed at the surface with a lockable cap. Well construction logs are provided in Appendix A.

Split spoon samples were collected from selected borings and interval depths to visually classify soils. Following installation of all wells, each well was developed using a surge and purge methodology. Development was continued for a minimum of one hour, until the water was free of fine-grained material to the extent practical.

Soil cuttings and purge water from well installation activities were containerized in 55-gallon steel drums and appropriately labeled and staged in the designated drum storage area for subsequent analysis and disposal.


3.0 GROUNDWATER SAMPLING

Groundwater samples from the installed air sparge and select monitoring wells were collected prior to and following the completion of pilot test activities to evaluate the dissolved-phase VOC concentration reduction in each well following the AS/SVE testing. Baseline (pre-test) groundwater samples were collected in air sparge wells AS-4S and AS-10S, and monitoring well MW-10S. Prior to collecting the baseline groundwater sample in air sparge well AS-10S, a sorbent sock was deployed in the well for approximately one day to remove the sheen (<0.01 inch) of light non-aqueous phase liquid (LNAPL) measured in well. Following the baseline sampling a new sorbent sock was deployed in AS-10S to continue passive LNAPL recovery. The sorbent sock then was temporarily removed during the AS testing and post-test groundwater sampling. Groundwater samples were collected from air sparge wells AS-4S and AS-10S, and monitoring wells MW-4S and MW-10S after the completion of each AS/SVE test.

Each sample well was purged and sampled utilizing a modified low-flow methodology in accordance with the EPA Groundwater Sampling Guidelines. Groundwater chemistry parameters (DO, temperature, ORP, conductivity, turbidity, and pH) were recorded at regular intervals during purging at each well location. Upon stabilization of the parameter readings, the groundwater sample was collected into pre-preserved, laboratory-prepared bottle-ware, and placed in a cooler on ice. Appropriate chain of custody documentation accompanied the samples submitted to Chemtech Consulting Group, Inc. (Chemtech), a City of Philadelphia certified Disadvantaged Business Enterprise, for analysis of VOCs by United States Environmental Protection Agency (EPA) Method 8260 and other select analyses. All laboratory data is included as Appendix B; a summary of analytical results for the groundwater samples collected during pilot testing are presented in Table 1. Monitoring well purge logs completed during sampling of the monitoring wells are presented in Appendix C.


4.0 PILOT TEST OBJECTIVES & METHODOLOGY

4.1 OVERVIEW

The pilot test was performed in accordance with the September 2014 Work Plan. Details regarding the remediation pilot testing objectives and methodologies are discussed below.

4.2 PILOT TEST OBJECTIVES

The primary objective of the remediation pilot testing was to collect data that will subsequently be used to determine the most appropriate remediation technology for the Site and to gather data to support a full-scale system design. Additionally, there were several specific data collection objectives to be accomplished through pilot testing. The data obtained during pilot testing included the following:

• vapor flow rates during SVE testing;

• vapor-phase VOC concentrations during SVE and AS/SVE;

• AS pressure and flow rates;

• changes in groundwater dissolved oxygen concentrations during AS; and,

• groundwater mounding during AS and AS/SVE tests.

The data obtained during pilot testing was interpreted and used in conjunction with laboratory sample data and hydrocarbon recovery calculations to evaluate the following:

• feasibility of SVE and AS/SVE to address adsorbed and dissolved-phase hydrocarbon impact;

• feasibility of AS/SVE to mitigate migration of the dissolved plume;

• vapor extraction ROI;

• vacuum versus vapor flow relationships for individual extraction wells; and,

• estimated AS ROI.

4.3 PILOT TEST METHODOLOGY

TRC completed on-site remediation technology pilot testing on October 28 and October 29, 2014 at two locations to evaluate the effectiveness of AS/SVE as a barrier to mitigate off-site migration of dissolved VOCs in groundwater. Pilot testing activities were performed using Groundwater & Environmental Services’ Data Acquisition and Processing Laboratory (DAPL). The DAPL unit is a self-contained platform that provides computerized real-time data acquisition and processing evaluation. The DAPL unit is equipped with pumps, sensors, and hardware needed to perform SVE and AS tests. On-board sensors monitor and continuously log system operating conditions and field responses, including vacuum/pressure responses, vapor flow rates, and groundwater levels. The on-board computer manages and integrates the incoming data and performs real-time calculations and analyses to allow for the immediate evaluation of test conditions. This allows for flexibility in customizing the pilot test to site conditions.


The pilot testing activities progressed in the following manner:

• SVE test at extraction well SVE-4S;

• AS tests air sparge well AS-4S;

• AS/SVE tests concurrently at air sparge well AS-4S and extraction well SVE-4S.

• SVE test at monitoring well SVE-10S;

• AS test air sparge well AS-10S; and

• AS/SVE tests concurrently at air sparge well AS-10S and extraction well SVE-10S.

Recovered soil vapors were treated via two vapor-phase granular activated carbon (GAC) units, plumbed in series, prior to discharging to the atmosphere. An authorization to discharge treated soil vapors in lieu of a permit was granted by the City of Philadelphia Department of Public Health Air Management Services on October 10, 2014, and is included in Appendix D.

4.3.1 Data Collection Techniques

Prior to the start of test activities, static measurements of groundwater levels, well casing atmosphere headspace readings, and dissolved oxygen (DO) concentrations were recorded from each monitoring well. These measurements were recorded to provide base-line data to compare to subsequent readings. A summary of the groundwater levels, headspace readings, and DO concentrations are included in Table 3.

During SVE, AS, and AS/SVE tests, the resulting vacuum or pressure influence was periodically measured at surrounding observation wells using Magnehelic differential pressure gauges connected to sample ports on the sealed observation wells. Manual groundwater level measurements were also periodically measured at surrounding observation wells.

During testing, the influent vapor stream was periodically screened for VOCs using a photoionization detector (PID). Vapor samples were also periodically screened in the field for percent oxygen, carbon monoxide, carbon dioxide, methane, and lower explosive limit (LEL) with either a landfill gas meter or multi-gas meter. Pre-treatment recovered vapor samples were collected for laboratory analysis to determine the vapor-phase hydrocarbon recovery concentrations and to calculate the recovery rates at each test location. The influent vapor samples were collected and submitted by TRC to Accutest Laboratories, Inc. (Accutest) and Chemtech for analysis of VOCs by EPA Methods TO-3 and TO-15, respectively. All laboratory data is included as Appendix B; a summary of analytical results for vapor samples collected during pilot testing are presented in Table 2.

4.3.2 Soil Vapor Extraction Test Methodology

SVE tests were performed at extraction wells SVE-4S and SVE-10S. During the SVE tests, vacuum was applied to the extraction wells in various increments. Groundwater mounding was monitored at the extraction well; vacuum response and groundwater upwelling (mounding) were monitored at nearby monitoring wells to observe vacuum influence under testing conditions.


4.3.3 Air Sparge Test Methodology

Air sparge only tests were performed at air sparge wells AS-4S and AS-10S to determine the AS radius-of-influence (ROI) based on measured pressure influences, DO increases, VOC vapor headspace concentration increases, and groundwater mounding at surrounding observation wells. This was accomplished by injecting compressed air into the sparge point until the breakout pressure was reached and sparge flow was observed.

DO measurements were obtained from select observation wells before and after AS testing. This was accomplished by submerging the sonde of a calibrated water quality measurement device (YSI 550A) in the observation wells. The data were collected to evaluate changes in dissolved oxygen concentration as a result of the injection of compressed air and the saturation of oxygen into the groundwater.

4.3.4 Air Sparge/Soil Vapor Extraction Test Methodology

Two AS/SVE tests were performed utilizing AS wells AS-4S and AS-10S in conjunction with SVE at extraction wells SVE-4S and SVE-10S, respectively. The AS/SVE tests were performed to verify the AS ROI and to identify increases, if any, in the hydrocarbon recovery rate at soil vapor recovery wells due to the addition of AS at the corresponding sparge wells. After the AS only test data was obtained, the optimal vacuum determined from the SVE only testing was applied at the extraction well.


5.0 PILOT TEST RESULTS

Pilot testing activities were performed October 28 and October 29 to evaluate the feasibility of AS/SVE as a remediation technology to address subsurface contamination at the Site. The following is a summary of the individual tests and subsequent results. A summary of the pilot testing data is included in Table 3 through Table 5. A summary of the pilot test field notes is presented as Appendix E. The pilot test vapor extraction VOC concentration and flow rate verses vacuum results and vacuum extraction ROI are presented as Appendix F and Appendix G, respectively.

6.0 PILOT TEST SUMMARY & CONCLUSIONS

Results from the testing activities completed in October 2014, indicate that AS/SVE could be implemented to mitigate the migration of dissolved-phase hydrocarbon impacts at the Site. A summary of the results and conclusions for the tested technologies are discussed in the following sections.

6.1 SUMMARY OF RESULTS

Results from the AS, SVE, and AS/SVE testing completed in October 2014 indicate air sparge radii-of-influence ranged from 13 feet (AS-10S) to 18 feet (AS-4S) at pressures of approximately 15.5 to 16.5 psig and flow rates of 11.2 to 14.8 scfm. During AS/SVE testing, vapor flow rates ranged from 57.8 scfm to 109.8 scfm at vacuums ranging from 63 i.w. to 40 i.w.

Based on the groundwater mounding (0.1 feet minimum), pressure influence observations (0.10 i.w. minimum), VOC vapor headspace concentration, and DO concentration data collected at observation wells during the testing, ROI calculations were performed for each AS testing location. The calculated ROI during each test was 13 feet for AS-10S and 18 feet for AS-4S. The average ROI calculated for the AS tests was 15 feet. The design ROI calculated for the AS tests was 11 feet by using a design factor of 1.25. A summary of air sparge data summary and estimated radius-of-influence is presented in Table 5.

A general increase in DO concentration was observed following AS and AS/SVE testing activities conducted at wells AS-4S/SVE-4S and AS-10S/SVE-10S. Under static conditions, DO measurements ranged from 0.13 mg/L to 0.44 mg/L. Following AS testing at both AS-4S and AS-10S, DO measurements at surrounding observation wells ranged from 0.14 mg/L to 10.28 mg/L.

Recovered vapor flow rates during SVE testing ranged from approximately 23.5 scfm to 111.0 scfm at vacuums ranging from approximately 20 i.w. to 63 i.w. The vacuum ROI during SVE testing at extraction well SVE-4S was 68 feet, 88 feet, and 92 feet based on the three vacuum test steps of 24 i.w., 47 i.w., and 63 i.w., respectively. It should be noted that the SVE testing at well SVE-4S resulted in non-uniform vacuum influence readings that is likely due to the heterogeneous characteristics of the subsurface geology local to monitoring point MP-4S-3, where relatively little pressure/vacuum influence was observed in comparison to other monitoring points. The vacuum ROI during SVE testing at extraction well SVE-10S was 58 feet, 60 feet, and 64 feet based on the three vacuum test steps of 20 i.w., 30 i.w., and 40 i.w., respectively, assuming a minimal effective vacuum of 0.10 i.w.

The highest vapor-phase mass recovery rates calculated during SVE testing (15.2 lbs/day of BTEX, 543 lbs/day of C1-C4, and 89.2 lbs/day of >C4-C10 hydrocarbons) were calculated from extraction well SVE-10S. The highest vapor-phase mass recovery rates during AS/SVE testing were also observed at extraction well SVE-10S (16.0 lbs/day of BTEX, 529 lbs/day of C1-C4, and 89.2 lbs/day of >C4-C10 hydrocarbons). Lower hydrocarbon recovery rates were calculated during SVE and AS/SVE testing at SVE-4S (up to 1.3 lbs/day of BTEX, 198 lbs/day of C1-C4, and 19.4 lbs/day of >C4-C10 hydrocarbons), though the recovery was less in comparison to the results observed at extraction well SVE-10S. The laboratory data and field measurements indicate that vapor-phase hydrocarbon recovery rates generally remained stable with the initiation of AS activities.


6.2 CONCLUSIONS

6.2.1 Soil Vapor Extraction

Results of pilot testing indicate that while SVE, as a stand-alone technology, would mitigate unsaturated adsorbed-phase hydrocarbons, it would not comprehensively address the dissolved-phase hydrocarbon impact or comprehensively mitigate the migration of the dissolved-phase hydrocarbons. TRC considers SVE to be an adequate method for remediating the adsorbed-phase hydrocarbons present in the subsurface but would need to be coupled with another remediation technology (e.g., air sparge, EAB) to fully address the remediation goals of the Site.

The pilot test results also indicate that bioventing may be an applicable technology to reduce the adsorbed-phase hydrocarbons in the unsaturated zone of the subsurface. Bioventing enhances the activity of the indigenous bacteria by inducing air (i.e., oxygen) flow into the unsaturated zone and, if necessary, by adding nutrients. Bioventing is similar to SVE, but instead of recovering contaminants through volatilization, bioventing enhances biodegradation rates of constituents and minimizes volatilization through the application of a lower air flow rate than SVE. The elevated concentrations of CH4 and CO2, which are generated during the natural biodegradation process, measured during the pilot test activities are also indicators that bioventing may be an applicable technology which can further promote the biodegradation process of the hydrocarbon impacts. However, it should be noted, that like SVE, bioventing would need to be coupled with another remediation technology to fully address the Site remediation goals.

6.2.2 Air Sparge/Soil Vapor Extraction

Based on the results of the testing, AS/SVE is recommended as a remedial approach to address adsorbed- and dissolved-phase hydrocarbon impacts and to mitigate the migration of dissolved-phase hydrocarbons. A combination AS/SVE system appears to be an effective approach to address the dissolved and adsorbed phase hydrocarbon impact within the test area at the Site due to the moderate to highly permeable unsaturated and saturated soils which were a contributing factor to the magnitude of influence exhibited in the observation wells from the SVE and AS testing. Field screening measurements collected during testing activities generally indicated that there is adsorbed- and dissolved-phase hydrocarbon impact as elevated VOC vapor concentration increases were measured in the observation well headspaces before the SVE tests and following both AS only tests.

Additionally, dissolved-phase BTEX concentration reductions of 66% and 30% were measured in air sparge wells AS-4S and AS-10S pre- and post-test groundwater samples. A negligible reduction of 1% was measured in monitoring well MW-4S when comparing the post-test sampling results to the May 2014 groundwater sampling data. A concentration increase of 22% was measured in monitoring well MW-10S, which was likely from the dispersion of the detected residual LNAPL in air sparge well AS-10S that was not passively recovered with the sorbent sock prior to the pilot test activities. However, it is anticipated that with continued operation of an AS/SVE system, the dissolved-phased VOC concentrations measured in monitoring well MW-10S will decrease. These measurements further indicate that simultaneous SVE and AS may be an appropriate remediation technique to mitigate the off-Site migration of dissolved-phase VOC impacts.


7.0 FUTURE SITE ACTIVITIES

As described in the September 2014 Work Plan the EAB pilot test will be completed following the AS/SVE pilot test. The EAB pilot test injection is scheduled for November 2014. The results of the EAB pilot test will be evaluated in comparison to the AS/SVE test results to determine an effective remediation technology for the Site and following the receipt of the post EAB pilot test groundwater sampling results. The results and analysis of the EAB pilot test and comparison to the results of the AS/SVE testing will be submitted to PGW under a separate cover.

NOTES:The oxygen gas levels within the observation well headspaces were measured using a multi-gas meter and a landfill gas meter.The landfill gas meter was not available for use on October 28, 2014, therefore no measurements were reported for methane, carbon dioxide, and oxygen.The Post-AS water depths for wells MW-4S, MP-4S-3, MW-10S, EAB-10S, SVE-10S, and MP-10S-3 were calculated by adding the measured level change from the transducer deployed in each well during testing to the measured baseline depth.The post-AS/SVE depth to water was unable to be measured in wells AS-4S, MP-4S-2, and MP-4S-3 due to equipment malfunction.

NOTES:1 - Maximum pressure established during testing.2 - Flow established at maximum pressure during test.3 - Effective groundwater table mounding (in feet) recorded due to air sparging effects. Mininal effective groundwater influence was assumed to be 0.1 feet.4 - Effective pressure (in inches of water column) recorded due to air sparging effects. Minimal effective pressure influence was assumed to be 0.1 inches of water.5 - Difference in recorded dissolved oxygen readings (in milligrams per liter) from pre-test to post-test conditions is assumed to be a 50% increase.6 - Minimal significant increase in recorded PID headspace from pre-test conditions (in parts per million) is assumed to be 200%.7 - Determined by averaging the maximum distances to observed significant influences from each of the air sparge tests.8 - Based on engineering best preactices, the design radius-of-influence was determined by applying a design factor of 1.25 to the average maximum influence. The design factor is subject to revision during the system design.

of 13


3.0 PREPARATION FOR PRESSURE TEST OF PIPING AND EQUIPMENT (Cont'd)

3.10 Precautions shall be taken, by opening vents or by other means, to

prevent building up excessive pressure in equipment adjacent to portions of the piping system under test when slip or blind flanges are not used to isolate the equipment.

3.11 All hand-operated valves within a test loop shall be temporarily tagged

with large red "CAUTION" tags or a similar identification to avoid accidental operation during filling or testing. These will also help in identifying the test system.

3.12 Temporary pipe supports shall be added and spring hangers shall be

blocked where necessary before the addition of test water. This shall prevent overstressing of the pipe to be tested.

3.13 Testing of expansion joints will require review by the Company

Representative prior to testing. The instructions and/or recommendations of the manufacturer shall be observed.

3.14 The Contractor shall provide a time/pressure chart recorder for the

test. The Company shall have the option to provide the recorder to be used on all pressure tests. All completed charts shall be turned over to the Company for permanent record.

4.0 PRESSURE TEST OF VESSELS

The pressure test performed on field fabricated vessels shall be in accordance with the provisions of the latest edition of the ASME Boiler and Pressure Vessel Code, Section VIII, as applicable.

4.1 All field fabricated vessels shall receive a hydrostatic test where supports,

foundations and subsoil permit, or where the static head of test fluid does not impose unreasonable thickness requirements. Project documents will specify exact testing requirements.

4.2 Where field fabrication is performed, the field pressure tests shall be

made by the sub-contractor. When a straight hydrostatic test cannot be performed, a combined pneumatic/hydrostatic test shall be performed upon Company approval.

5.0 PRESSURE TEST OF PIPING AND EQUIPMENT

5.1 Testing of the piping and equipment installation shall be performed on all interconnected lines of the same nominal flange rating. The breaking of joints to insert blanks for hydrostatic testing shall be avoided whenever possible.

5.2 The hydrostatic test pressure of a system shall be determined as follows:

5.2.1 The hydrostatic test pressure shall be 1.5 times the design pressure of the weakest component multiplied by the ratio of the allowable stress at test temperature to the allowable stress at the design temperature. For a design temperature above the test temperature, the minimum hydrostatic test pressure shall be as follows:

PT = 1.5P* (ST/S) if TT < TD, where PT = Hydrostatic test pressure, PSIG

P = Design pressure, PSIG

of 13


5.0 PRESSURE TEST OF PIPING AND EQUIPMENT (Cont’d)

ST = Allowable stress at test temperature, PSIG

S = Allowable stress at design temperature, PSIG TT = Test Temperature, °F TD = Design Temperature, °F

5.2.2 The hydrostatic test pressure for the entire system shall be the highest permissible pressure for the weakest component in the system as defined by Section 5.2.1 above.

5.2.3 Under certain design conditions, the stress resulting from the test

pressure (PT) as defined above could exceed the specified yield strength at test temperature. A check shall be made to determine if this condition exists. In such cases the test pressure shall be reduced to the maximum pressure that does not exceed the specified yield strength at test temperature.

5.2.4 A closed valve may be used as the system limit only upon

Company approval. The test pressure may not exceed that used in its actual seat test. If the system test pressure is to be higher, it is recommended that the valve be opened and blanked, or removed to allow blanking of the flange.

5.3 Units or sections of piping where moisture cannot be tolerated due

to process considerations shall be tested pneumatically. Nitrogen shall be used unless the Company specifies another test medium.

of 13



5.3.1 The following shall be pneumatically tested at 110% of design pressure:

5.3.2 Vacuum lines shall be pneumatically tested at 50 PSIG.

5.4 The following procedures shall be followed during pressure testing:

5.4.1 Piping and equipment shall be thoroughly vented of air during filling. 5.4.2 The liquid used for hydrostatic testing shall be inserted at 60° F minimum. Below this temperature approval shall be obtained from the Company. The test pressure shall be applied after the metal and its contents stabilize at about the same temperature. Metal temperature shall not be allowed to fall below 35° F while the metal is under stress. If the temperature is below 35° F, the temperature of the test water shall be monitored. 5.4.3 If it is proposed that the hydrostatic test fluid be other than water

or that a chemical be added to the water, the Company shall be consulted and approval granted in writing before proceeding with the testing operation.

of 13



5.4.4 In freezing weather, the Company shall be consulted as to whether an anti-freeze be thoroughly mixed with the test water or the test be postponed until warmer weather. If the

hydrostatic test is performed in freezing weather, all lines shall be thoroughly drained of water, and all used anti- freeze shall be properly disposed after testing.

5.4.5 Water with a high chloride content shall not be used for testing Austenitic stainless steel piping and equipment.

Water of moderate chloride content, 50-100 PPM, may be used provided 2% to 4% sodium nitrate is added.

5.4.6 Exchanger or vessels previously shop or field pressure

tested may, at the option of the Company, be included in the test simultaneously with the connecting piping. During such a retest, the test pressure shall not exceed the lowest test pressure of any exchanger or vessel included in the test.

5.4.7 Where an exchanger or vessel has been blanked-off during

pressure test of the piping, it shall not be necessary to pressure test the joint after the blank is removed. This joint shall be observed at startup.

5.4.8 Pumps, turbines, blowers, compressors and control valves

shall not be subjected to pressure test. 5.4.9 Test pressure readings may be taken at a low point in a

system provided static head is subtracted from the pressure reading to ensure the proper test pressure is obtained.

5.4.10 The system under test shall be held at full test pressure until

all joints are examined. The duration of the pressure tests shall be as required below. The Project Specification may require a pressure test of longer duration.

Station systems (49 CFR Part 192 systems) shall be a minimum of eight (8) hours in duration.

5.4.10.2 Pressure tests conducted in the Richmond and Passyunk

Plant facilities (49 CFR Part 192 systems) in which the piping is to operate at a hoop stress that is 30% or more of SMYS shall be a minimum of eight (8) hours in duration.


Plant facilities (49 CFR Part 192 systems) in which the piping is to operate at a hoop stress that is less than 30% of SMYS shall be a minimum of one (1) hour in duration.


Plant facilities (NFPA 59A - LNG systems) shall be a minimum of one (1) hour in duration.

5.4.10.5 Systems that do not fall under the jurisdiction of 49 CFR

Part192 or NFPA 59A (LNG) shall adhere to the pressure testing requirements of ASME B31.3 and the pressure tests shall be a minimum of one (1) hour in duration.

5.4.11 If the testing medium is subject to thermal expansion during the

period of test, provisions shall be made for the relief of the excess pressure.

5.4.12 Sewers and non-pressure drains shall be filled with water to grade,

but no pressure other than the static head shall be applied. All joints will be visually examined for leakage.

of 13


6.0 SPECIAL REQUIREMENTS OF PNEUMATIC TESTING

6.1 If the piping is tested pneumatically, the test pressure shall be 110%

of the design pressure. Pneumatic testing involves a hazard due to possible release of energy stored in compressed gas. Every precaution shall be taken before and during pneumatic testing to assure the safety of personnel. Personnel not involved in the testing shall be excluded from the area. Particular care must be taken to minimize the chance of brittle failure of metals and thermoplastics. The test temperature is important in this regard and must be considered when the choice of material is made in the original design. The pressure shall be increased gradually in steps providing sufficient time to allow the piping to equalize strains during test and to check for leaks.

6.2 A pressure relief device shall be provided, having a set pressure not

higher than the test pressure plus the lesser of 50 psi or 10% of the test pressure.

6.3 All joints, welds and connections shall be swabbed with soap solution to

facilitate the detection of leaks.

6.4 If the pneumatic test pressure exceeds 20 PSIG, the pressure shall be held at 20 PSIG until all joints have been inspected for leaks with soap solution. If no leaks are found, the pressure shall be increased in increments of 15 PSIG until final test pressure is reached. Swabbing and inspection shall be repeated at each 15 PSIG increment as well as for the final test pressure. Time at full test pressure shall not be less than one hour.

6.5 Pneumatic test pressures in excess of 50 PSIG must be approved by the

Company.

6.6 Masking tape shall be applied across flanged joints, with a small hole for detecting leakage.

of 13


6.0 SPECIAL REQUIREMENTS OF PNEUMATIC TESTING (Cont’d)

6.7 When testing instrument air lines and other small systems, a

“bubbler” apparatus at the fill point may be used as a check on air leakage.

6.8 Tested systems shall be vented immediately upon successful

completion of the test. 7.0 HYDROSTATIC TESTING OF EXTERNALLY PRESSURED PIPING Lines in external pressure services shall be subjected to an internal

pressure test of ½ of the differential design pressure, but not less than a gauge pressure of 15 PSIG.

5.0 FABRICATION, PLACING AND SPACING OF REINFORCEMENT

5.1 All reinforcement shall be accurately located and mechanically secured against displacement by using iron tying wires at intersection and shall

be inspected and approved by the Authorized Representative before concrete is deposited.


Reinforced Concrete Standard 5.0 FABRICATION, PLACING AND SPACING OF REINFORCEMENT (Cont'd)

5.2 A concrete pour release slip is to be signed by the Authorized Representative before pour is made.

5.3 Where metal reinforcement is placed in the forms, it shall be free from

excessive amounts of mill and rust scale and of coatings of any character that will destroy or reduce the bond. Reinforcement appreciably reduced in cross sections will be rejected. Where there is a delay in disposition of concrete, reinforcement shall be inspected again, where necessary, and cleaned as directed by the Authorized Representative.

5.4 Reinforcement shall be formed to the dimensions indicated on the

drawings or called for in the specifications. Metal reinforcement shall not be bent or straightened in a manner that will injure the material. Bars with kinks or bends not shown on the Contract drawings will be rejected; all bars shall be bent cold.

5.5 The Contractor shall be responsible for the proper alignment of reinforcing

steel (including, but not limited to, rods, dowels, mats or mesh) and shall take steps to assure the proper alignment of any reinforcing steel which has become displaced subsequent to its initial installation. The provisions of the latest issue of the Concrete Reinforcing Steel Institute’s recommended practice for placing reinforcing bars shall be complied with by the Contractor. Supports for reinforcing will be as specified and will maintain the reinforcing in proper position within the concrete form.

6.0 ANCHORS, SLEEVES AND BUILT IN WORK

6.1 All the hangers, sleeves, anchors, inserts, wall castings, etc. shall be set and furnished by the Contractor. The Contractor shall take every precaution to ensure that they are not displaced when pouring concrete. Care shall be taken to see that sleeves and inserts are installed at the proper elevation.


Reinforced Concrete Standard 7.0 TESTS

7.1 Compression tests of the structural concrete shall be made in accordance with ASTM C-39 and ACI-318 requirements. The Contractor shall be responsible for the payment and performance of these tests.

7.2 The Authorized Representative shall have unrestricted access to plants at all times, and to materials, records and all other data pertaining to mixing, transferring, use and inspection of the ready mixed concrete.

7.3 It shall be the Contractor’s responsibility to prepare, identify and store specimens until picked up by the testing Company Representative. The preparation of the cylinders shall conform to the Making and Curing of Concrete Compressive and Flexural Test Specimens in Field Test, ASTM C-31. 7.4 Representative samples of test specimens shall be taken in accordance with Method of Sampling Fresh Concrete ASTM C-172. Three test

specimens shall be taken from each truckload. One each at the beginning, middle and end of the pour.

8.0 PLACING CONCRETE

8.1 Before placing concrete, all debris shall be removed from the spaces to be occupied by concrete, and forms thoroughly oiled or wetted. Free fall

of concrete shall be limited to prevent segregation of the aggregate.

8.2 Water shall be removed from excavations before concrete is deposited. Any flow of water into the excavation shall be diverted through proper side drains to a sump, or be removed by other approved methods. Drain pipes used for this purpose, on completion of pouring, shall be filled solid. Removal of water by pumping shall be continued for at least 4 hours after depositing concrete. For pits and similar spaces where tightness is required, removal of water shall be continued for 24 hours after placing.

8.3 Concrete placed in one separation shall be essentially level all around. Temporary bulkheads when necessary shall be located in general at points of minimum sheer.


Reinforced Concrete Standard 8.0 PLACING CONCRETE (Cont'd)

8.4 All construction joints shall be keyed and doweled; location of construction joints shall be determined in the field and approved by the Authorized Representative. Before placing concrete, adjoining construction joints shall be picked, brushed clean, and given a coat of neat cement grout. Provide additional reinforcement at joint if so required by the Authorized Representative.

8.5 All structural concrete shall be placed with the aid of mechanical vibrators.

The vibrators shall be of a type and design approved by the Authorized Representative and shall be capable of transmitting to the concrete not less than 3,000 impulses per minute. Enough vibrators shall be used to cause all the concrete to flow or settle readily into place.

8.6 The vibrators shall be of the internal type, applied directly to the concrete and not through the forms, except in sections too thin to permit

the insertion of the internal type, in which case form vibration may be employed at the discretion of the Authorized Representative. Methods of use of vibrators shall be such as to secure an even, dense surface, free from aggregate pockets or honeycombs. Vibration shall be supplemented by forking or spading by hand in the corners and angles of forms and along form surfaces while the concrete is plastic under vibratory actions.

8.7 In freezing weather, a suitable means shall be provided for maintaining a temperature not less than 50o F for not less than 72 hours, after placing. Methods of heating shall be approved by the Authorized Representative

and as recommended in ACI-306.

8.8 Hot weather work shall be in accordance with ACI-605. All concrete shall be protected against rapid drying and shall be given a spray coat of an approved liquid curing compounds per ASTM A-309 as soon as possible. All concrete shall be cured as per latest recommendations of the ACI.

8.9 All freshly placed concrete shall be protected from the elements and from

all defacement due to construction operations.


Reinforced Concrete Standard 8.0 PLACING CONCRETE (Cont'd)

8.10 Concrete shall be deposited as nearly as practicable in its final position to avoid segregation due to re-handling of flowing. The concreting shall be carried on at such a rate that the concrete is at all times plastic and flows readily into spaces between the bars. No concrete that has partially hardened or been contaminated by foreign materials shall be deposited on the work, nor shall re-tampered concrete be used.

8.11 Precaution shall be taken to keep all concrete moist for a period of 7 days after being deposited. This shall be done by covering of wet sand immediately after setting and thoroughly wet twice a day, or by frequent sprinkling with a hose to keep it moist, or other approved methods.

9.0 FINISHING OF CONCRETE SURFACES

9.1 Concrete slabs and topping fills which are to remain exposed shall be finished monolithically as follows:

9.1.1 After concrete has been placed and thoroughly compacted by

vibration, the surface shall be struck off at the proper elevation by means of previously set screeds.

9.1.2 Fines shall be brought to the surfaces and coarse aggregate pressed down by means of a darby.

9.1.3 No floating or troweling shall be done on floor slabs while the material is wet or sloppy. Finishing operations shall be delayed until all surface water has disappeared.
