1.0 INTRODUCTION Roux Associates, Inc. (Roux Associates) has prepared the following report for ExxonMobil

Refining and Supply Company (ExxonMobil) to summarize the results of the Phase II Soil

Vapor Extraction (SVE) Pilot Study for the intersection of Norman Avenue, Bridgewater Street,

Apollo Street, and Van Dam Street (Pilot Study Area) in Greenpoint, Brooklyn, New York

(Site). The Pilot Study Area is located within a Commercial/Industrial Area, as shown on

Figure 1. The phase II pilot study was performed in accordance with the “Scope of Work for the

Phase II Soil Vapor Extraction Pilot Study” (Phase II Pilot Study Work Plan [Roux Associates,

2007]) dated March 22, 2007, approved by the New York State Department of Environmental

Conservation (NYSDEC) in a letter dated April 24, 2007.

The first phase of the SVE pilot study, which was conducted in November/December 2006,

indicated that vertical SVE wells could potentially be effective for mitigation of the

concentrations of methane and other volatile organic compounds (VOCs) in the shallow soil

vapor (i.e., less than 8 feet depth below the land surface) beneath the Pilot Study Area. The

results of the first phase SVE pilot study was presented in the report dated January 31, 2007,

titled “Soil Vapor Extraction/Bioventing Pilot Study Summary Report” (Roux Associates, 2007).

The purpose of the phase II SVE pilot study was to provide additional information necessary to

proceed with a full-scale design of a SVE system for mitigation of methane and VOCs in the

shallow soil vapor (i.e., less than 8 feet depth below the land surface). Specifically, the phase II

SVE pilot study was conducted over a longer duration involving multiple SVE wells to address

the following issues:

• Confirm that the radius of influence (ROI) of 75 feet, observed during the first phase, can be achieved at other locations;

• Evaluate optimal SVE well screen interval depth;

• Further evaluate the potential effect of street utilities and existing building foundation on the required spacing of the SVE wells; and

• Determine the appropriate off-gas treatment technology and efficiency during long-term operation of the SVE system.

This report describes the scope of work for phase II SVE pilot testing, presents the results of the

phase II SVE pilot testing, provides the rationale and objectives for a vapor mitigation system, a

conceptual SVE system design, and preliminary schedule for implementation of a full-scale SVE

system. Background information regarding the soil vapor investigations previously completed

within the area is provided in the report dated September 29, 2006, titled “Phase IV Soil Vapor

Investigation Report” (Roux Associates, 2006a), as well as the report dated March 30, 2007,

titled “Biannual Soil Vapor Sampling – First Quarter 2007” (Roux Associates, 2007b).


2.0 PHASE II PILOT STUDY SCOPE OF WORK The Phase II SVE Pilot Study consisted of the following activities:

• Installation of Pilot Study Wells and Monitoring Points; and

• SVE Pilot Testing and Performance Monitoring.

A description of each activity is provided below.

2.1 Installation of Phase II Pilot Study Wells Three SVE wells (SVE-4, SVE-5, SVE-6) and seven sets of nested soil vapor monitoring points

(MP-SVE-4 through MP-SVE-10) were installed for the phase II pilot study. The phase II pilot

study also utilized existing SVE well (SVE-3), paired vapor monitoring points (MP-1, MP-2,

MP-5, MP-6, MP-7, MP-9, MP-10, and MP-11), and nested vapor monitoring points

(MP-SVE-1, MP-SVE-2, and MP-SVE-3). The location of the phase II pilot study SVE wells

and monitoring points are shown on Figure 2.

In accordance with ExxonMobil pre-drilling protocols, soils were excavated at all proposed

locations from land surface to 5 feet below land surface (ft bls) using an air knife before intrusive

activities began. The SVE wells were installed using a hollow-stem auger drill rig by Aquifer

Drilling and Testing, Inc. under the oversight of Roux Associates. Each well is constructed of

4-inch diameter Schedule 40 polyvinyl chloride (PVC). The SVE wells have the following

screened intervals: SVE-5 is screened from 7 to 12 ft bls; both SVE-4 and SVE-6 are screened

from approximately 13 to 18 ft bls. The existing well SVE-3 was screened from 13 to 18 ft bls.

The construction details of the SVE wells are shown on Figure 3.

The nested soil vapor monitoring points MP-SVE-4 through MP-SVE-10 each consist of three

points (shallow, intermediate, and deep) installed at depth intervals of 2 to 3, 7 to 8, and 14 to

15 ft bls, respectively. The nested soil vapor monitoring points were installed using a

Geoprobe™ rig following the same techniques and methods used during the first phase of the

pilot study. The construction details of the soil vapor monitoring points are shown on Figure 4.

The existing paired soil vapor monitoring points MP-1, MP-2, MP-5, MP-6, MP-7, MP-9,

MP-10, MP-11 were previously installed as part of the offsite soil vapor investigation and consist


of a shallow and deep point at each location. The shallow and deep monitoring points at each

location are spaced about 4 feet from one another. The shallow points (e.g., MP-1S) were

installed to a depth of 2 to 3 ft bls and the deep points (e.g., MP-1D) were installed to a depth of

7 to 8 ft bls. The paired deep points (e.g., MP-1D) were installed at the same depth interval as

that of the intermediate points of the nested vapor monitoring points (e.g., MP-SVE-4I). The

construction details of the existing soil vapor monitoring points are shown on Figure 5.

2.2 Phase II SVE Pilot Testing Methodology In accordance with the Phase II Pilot Study Work Plan (Roux Associates, 2007), the pilot testing

was conducted over a five-week period from May 18, 2007 to June 21, 2007. Each week an

SVE test was conducted on one of the four extractions wells for approximately 72 hours, with

associated soil vapor sampling and monitoring to evaluate subsurface response at surrounding

locations. During the phase II SVE pilot testing, an internal combustion engine (ICE) was used

as both a vacuum blower and as off-gas treatment for the methane and other VOCs in the

extracted soil vapor. The ICE engines used during the phase II pilot study were provided by

Brilliant Lewis Environmental Services, LLC, located in Lakewood, New Jersey. Each ICE

engine was equipped with an automatic controller, an emission control system, and a catalytic

converter and was sized to handle 150 standard cubic feet per minute (scfm) at a vacuum of

20 inches of mercury. The ICE engines are designed to favor methane and other VOCs extracted

from the SVE wells as the primary fuel source, and automatically adjust the supplemental fuel

(liquid propane) to extracted vapor ratio to compensate changing influent hydrocarbon

concentrations and maintain the optimal air/fuel ratio and keep the temperature of the catalytic

converter at or slightly below 1,200 degrees Fahrenheit. The liquid propane was supplied in

100-pound cylinders. The ICE and propane cylinders were kept under constant 24-hour around

the clock surveillance during the course of each test to ensure security and prevent tampering

with the equipment.

2.2.1 Soil Vapor Screening and Monitoring During the pilot study, soil vapor samples were collected for laboratory analysis prior to

(i.e., baseline) and at the conclusion (i.e., endpoint) of each 72-hour testing period. In general,

the baseline samples of each test were collected from existing vapor monitoring points (MP-1,

MP-2, MP-5, MP-6, MP-7, MP-9, MP-10, MP-11, MP-SVE-1, MP-SVE-2, and MP-SVE-3) and

newly-installed nested vapor monitoring points (MP-SVE-4 through MP-SVE-10). The endpoint

samples of each test were collected from selected vapor monitoring points located within the

radius of influence of the test as estimated from the real time monitoring results. With the

exception of the last test at SVE-3, the soil vapor air samples were collected and submitted for

VOC analysis using United States Environmental Protection Agency (USEPA) Method TO-15

and for methane analysis using USEPA Method TO-3. Following receipt of the samples,

Accutest initially screened the samples. Specially, those samples that contain benzene

concentrations greater than 10,000 parts per billion by volume (ppbv) would be analyzed by

Method TO-3 (in order to avoid fouling the more sensitive TO-15 instruments), while those

samples that contain benzene concentrations less than 10,000 ppbv would continue to be

analyzed by TO-15. The baseline vapor samples collected on June 18, 2007 and endpoint

samples collected on June 21, 2007 for the test on SVE-3 were analyzed for VOCs using a

reduced TO-3 list, focusing on benzene, toluene, ethylbenzene and xylene (BTEX) and methane

only. The laboratory, AccuTest in Dayton, New Jersey was utilized for all the sample analysis.

The results of the soil vapor sampling are summarized in Table 1. The laboratory analytical

results for the soil vapor sampling are provided in Appendix A.

The vacuum response, lower explosive limit (LEL), oxygen, and VOC concentrations (i.e., PID

readings) were monitored at the soil vapor monitoring points on an ongoing basis during each

testing phase using a digital gas pressure manometer or magnehelic vacuum gauges, and multi-

gas meters (MultiRAE Plus). The multi-gas meters were calibrated every eight hours or at least

daily. LEL was measured as a percentage of the lower explosion limit for methane (where 100%

LEL equals 50,000 parts per million volume [ppmv] methane). Oxygen was measured as percent

volume, and VOC concentrations were measured as ppmv. Field readings were recorded on

forms that have been compiled and included in Appendix B.

2.2.2 ICE Engine Performance Field Monitoring During the pilot study, ICE engine performance was monitored on a continuous basis with

parameters recorded on data sheets every two hours. The monitoring of the ICE engine consisted

of periodic readings of the information provided by the automatic controller, including calculated

wellhead vacuum, extracted air flowrate from the SVE well, total flowrate (extracted air,

supplemental fuel, and engine dilution air), the British thermal unit (BTU)/hour levels that is


entering the ICE from the SVE well, methane equivalent of extracted vapor (ppmv), and

supplemental fuel valve ratio status. VOC concentrations of ICE influent and effluent (stack

offgas) were monitored every two hours using a multigas meter (MultiRAE Plus). Field readings

of the system parameters were included in Appendix C.

2.2.3 Community Air Monitoring and Utility Manhole Screening During the pilot study, VOC concentrations (i.e., PID readings) were monitored using a multi-

gas meter on an ongoing basis at upwind and downwind locations, approximately 20 to 30 ft

away from the ICE engine(s). The community air monitoring results are provided in

Appendix D.

In addition, five utility manholes (MH-1, MH-2, MH-3, MH-4, and MH-5) in the pilot study area

were screened for the presence of VOCs, oxygen, and percent LEL. The approximate locations

of the utility manholes are shown on Figure 2. The summary of the utility manhole screening

data is provided in Appendix E.

2.3 SVE Test Summary The phase II SVE pilot test phase consisted of the following five separate tests conducted

sequentially:

• SVE-5 test (May 18, 2007 – May 24, 2007);

• SVE-4 first test (May 29, 2007 – June 1, 2007);

• SVE-4 second test (June 5, 2007 – June 8, 2007);

• SVE-6 test (June 11, 2007 – June 14, 2007); and

• SVE-3 test (June 18, 2007 – June 21, 2007).

SVE-5 is the only well with a shallower screen interval (7-12 ft bls), compared to a deeper screen

interval (13-18 ft bls) for other wells (SVE-3, SVE-4, and SVE-6). The ICE engine is designed

to automatically adjust the well valve opening status and wellhead vacuum levels to prevent the

temperature of the catalytic converter from exceeding 1,200 degrees Fahrenheit, based on the

subsurface soil vapor VOC concentrations. Thus, the actual wellhead vacuum that could be

achieved would be dependent on the subsurface soil permeability and the VOC concentration in

the extracted soil vapor. Initially, the tests on SVE-5 and SVE-4 utilized a single ICE engine. In

order to expand the radius of influence and increase vacuum and extracted air flowrates, the

second test on SVE-4 and the tests on SVE-6 and SVE-3 utilized two ICE engines operating in

parallel. Each test was conducted for approximately 72 hours or until a near steady-state

condition with respect to subsurface radius of influence has reached. A minimum of three days

was allotted between SVE tests in order to assess the rebound in soil vapor concentrations and to

allow conditions to stabilize prior to conducting the next test.

As discussed above, the 100-pound liquid propane gas cylinders were used as makeup fuel

during the engine startup and operation periods. Whenever the propane gas cylinder was empty,

the ICE would shut off automatically, and then the propane tank would be changed out and the

engine restarted. The estimated time between change-out of the propane gas cylinders was

recorded to calculate the makeup propane usage rate (lbs/hour). Typically, it took approximately

between 45 minutes to 1 hour for the wellhead vacuum and air flowrates to reach steady

conditions after the initial startup or restart of the ICE engines.


3.0 PILOT STUDY RESULTS The following section discusses the results of the phase II SVE pilot study. A summary of phase

II SVE pilot study results is presented in Table 2. The radius of influence (ROI) calculations for

each test, using the 0.1 inch water column (in. w.c.) “rule of thumb” as the minimum vacuum

response, are presented in Figures 6 through 10. The methane concentrations in both 2-3 ft bls

and 7-8 ft bls depths prior to and following each individual SVE test are presented in Figures 11

through 15. These figures also delineate the areas where, prior to each test, the methane

concentrations exceeded 12,500 ppmv at the 2 to 3 ft bls and 50,000 ppmv at the 7 to 8 ft bls;

and the area where by the conclusion of each test the concentrations had been reduced to below

these thresholds. In general, the highest levels of soil vapor methane concentrations are from

MP-SVE-10, which is adjacent to the BP Amoco Terminal. Benzene and methane

concentrations at 2-3 ft bls and 7-8 ft bls are presented in Plates 1 and 2, respectively. Detailed

discussion for each test is presented below.

3.1 SVE-5 Test Results The baseline soil vapor sampling for the SVE-5 test occurred on May 18, 2007. The test was

started on May 21, 2007 and completed on May 24, 2007, with a single ICE engine used for the

test. Approximately one hour after the engine startup, the wellhead vacuum stabilized at an

average of 3 in. w.c. with a flow rate of approximately 16 cfm. Overall, the methane equivalent

of the extracted vapor showed a slight decline trend, with an average of 25,580 ppmv. The

average of influent VOC concentrations (i.e., PID readings) was 222 ppmv. The SVE-5 test

removed an estimated average of 1.04 pounds per hour (lbs/hour) of methane and 0.06 lbs/hour

of VOCs. Based on the vacuum response at the soil gas monitoring points, the ROI for SVE-5

was estimated to be approximately 25 ft at 2-3 ft bls and 56 ft at 7-8 ft bls (Figure 6).

As shown in Figure 11, the pilot test at SVE-5 (screened from 7 to 12 ft bls) resulted in a

significant decrease of methane concentrations at 2-3 ft bls at two monitoring points

(MP-SVE-6S and MP-6S). The SVE-5 test was less effective in reducing the methane

concentrations at 7-8 ft bls (Figure 11). While the methane concentration soil gas monitoring

point MP-SVE-6I (located approximately 35 ft northwest from SVE-5) was reduced from

75,500 ppmv to 1,310 ppmv; the methane concentration at MP-6D (located approximately 35 ft

southeast from SVE-5) increased from 118,000 to 137,000 ppmv. The reduced level of

effectiveness at the 7 to 8 ft bls interval is believed to be attributable to the shallower screened

interval of SVE-5.

At the depth of 2-3 ft bls, the baseline benzene concentration at MP-SVE-1S (located

approximately 120 ft away and across Apollo Street from SVE-5) was 201,000 ppbv May 18,

2007. At the end of the test on SVE-5, benzene concentration at MP-SVE-1S decreased to

86,900 ppbv on May 24, 2007.

3.2 SVE-4 Test 1 Results The first test on SVE-4 (SVE-4 Test 1) was performed using a single ICE engine from May 29,

2007 to June 1, 2007. The subsurface methane concentrations remained at similar levels at

2-3 ft bls prior to the SVE-4 test (Figure 12), compared to that of the post SVE-5 test, even after

5 days of shut-down period. This indicated a slower rebound in shallow vapor concentrations

following mitigation. However, after the 5 day shut-down period the methane concentration at

7-8 ft bls had fully rebounded to pre-SVE-5 test levels. The quicker rebound at the 7 to 8 ft bls

interval is likely attributable to the greater depth and closer proximity to the free product.

The average wellhead vacuum of the test on SVE-4 was approximately 8 in. w.c. with a flow rate

of approximately 15 cfm. Overall, the methane equivalent of extracted vapor showed a slight

decline trend during the test, with an average of 54,048 ppmv. The average influent PID

readings was 154 ppmv. The SVE-4 test removed an average of 2.05 lbs/hour of methane and

0.04 lbs/hour of VOCs. The ROI for SVE-4 was estimated to be approximately 28 ft at 2-3 ft bls

and 58 ft at 7-8 ft bls (Figure 7).

As shown in Figure 12, the pilot test at SVE-4 resulted in a slight reduction in the methane

concentrations at 2-3 ft bls within the vicinity of SVE-4. However, all of these points were

already at concentrations less than 12,500 prior to the test. At 7-8 ft bls, there was reduction in

methane concentrations at several nearby monitoring points, including MP-SVE-3I, MP-SVE-4I,

MP-SVE-5I, MP-SVE-6I, and MP-11D. Based upon these reductions it was possible to infer the

mitigation area for 7 to 8 ft bls interval as shown in Figure 12.


At 2-3 ft bls, the benzene concentration in soil monitoring point MP-SVE-1S (located

approximately 100 feet and across Apollo Street from SVE-4) had a benzene concentration of

230,000 ppbv measured on May 29, 2007. At the end of SVE-4 test, benzene concentration at

MP-SVE-1S decreased to 34,300 ppbv on June 1, 2007.

3.3 SVE-4 Test 2 Results In order to improve the wellhead vacuum and air flowrate, a second test on SVE-4 (SVE-4

Test 2) was performed using two ICE engines from June 5, 2007 to June 8, 2007. The average

wellhead vacuum during the second test on SVE-4 was increased from 8 to 17 in. w.c. with a

flow rate of approximately 26 cfm (Table 2). Overall, the methane equivalent of extracted vapor

showed a slight decline trend during the test, with an average of 54,414 ppmv (Table 2). The

average influent PID readings were 287 ppmv. The second SVE-4 removed an average of

3.58 lbs/hour of methane and 0.12 lbs/hour of VOCs (Table 2). The ROI for the second SVE-4

test was estimated to be approximately 76 ft at 2-3 ft bls and 92 ft at 7-8 ft bls (Figure 8). Due to

the two ICE engines, the second SVE-4 test achieved a much higher ROI as well as VOC and

methane mass removal rate compared to first test on SVE-4.

As shown in Figure 13, the second test on SVE-4 resulted in reducing the methane

concentrations at 2-3 ft bls at soil gas monitoring points adjacent to SVE-4, including

MP-SVE-4S, MP-SVE-5S, MP-SVE-6S, and MP-10S. At 7-8 ft bls, the methane concentrations

adjacent to the SVE-4 well were also reduced, including MP-SVE-3I, MP-SVE-4I, MP-SVE-5I,

MP-SVE-6I, and MP-11D. Based upon the pre and post test concentrations it was possible to

delineate an area of mitigation at both the 2 to 3 ft bls and 7 to 8 ft bls depth intervals

(Figure 13). While the extent of this area is not equidistant in all directions, in some directions it

is greater than the ROI as estimated from the vacuum response data alone. The results of the

second test on SVE-4 also indicated that the ROI extended to monitoring points across the street

and under the adjacent existing building, which suggests that street utilities and existing building

foundation did not have a significant adverse effect on the ROI.

At depth of 2-3 ft bls, the benzene concentration at MP-SVE-6S (located approximately 90 feet

and on the other side of the adjacent building) decreased from 188,000 ppbv on June 5, 2007 to

97.9 ppbv on June 8, 2007.


3.4 SVE-6 Test Results The test on SVE-6 was performed using two ICE engines from June 11, 2007 to June 14, 2007.

In general, the SVE-6 test results are fairly similar to that of the second test on SVE-4. The

average wellhead vacuum of SVE-6 test was 17 in. w.c., with a flow rate of approximately

26 cfm (Table 3). Overall, the methane equivalent of extracted vapor showed a slight decline

trend during the test, with an average of 51,880 ppmv (Table 2). The influent PID readings were

219 ppmv. The SVE-6 Test removed an average of 3.41 lbs/hour of methane and 0.09 lbs/hour

of VOCs (Table 2). The ROI for SVE-6 was estimated to be approximately 56 ft at 2-3 ft bls and

108 ft at 7-8 ft bls (Figure 9).

As shown in Figure 14, the test on SVE-6 resulted in reducing the methane concentrations at

2-3 ft bls at soil gas monitoring points adjacent to SVE-6. At 7-8 ft bls, the methane

concentrations adjacent to the SVE-6 well were reduced significantly, including MP-SVE-6I,

MP-SVE-7I, MP-SVE-9I, and MP-6D (Figure 14). At both depth intervals it was possible to

delineate an area of mitigation. The extent of this area is generally slightly greater than the ROI

as estimated from the vacuum response data alone.

The test on SVE-6 also resulted in a decrease of benzene concentrations at depths 2-3 ft bls and

7-8 ft bls for most soil gas monitoring points located within the ROI (Plates 1 and 2).

3.5 SVE-3 Test Results The test on SVE-3 was performed using two ICE engines from June 18, 2007 to June 21, 2007.

Compared to the tests on SVE 4 and SVE-6, the test on SVE-3 exhibited a slightly lower

wellhead vacuum but at slightly higher air flowrates, most likely due to more permeable

subsurface formation conditions at the SVE-3 location. The more permeable subsurface is

consistent with the field observations and results noted during the first phase of the SVE pilot

study. The average wellhead vacuum during the test on SVE-3 was 14 in. w.c., with a flow rate

of approximately 35 cfm (Table 3). Overall, the methane equivalent of extracted vapor showed a

slight decline trend during the test, with an average of 41,399 ppmv (Table 2). The average

influent PID readings were 462 ppmv. The test on SVE-3 removed an average of 3.67 lbs/hour

of methane and 0.26 lbs/hour of VOCs (Table 2). The ROI for the SVE-3 test was estimated to

be approximately 88 ft at 2-3 ft bls and 120 ft at 7-8 ft bls (Figure 10).


As shown in Figure 15, the test on SVE-3 resulted in a reduction of the methane concentrations

at 2-3 ft bls at most soil gas monitoring points adjacent to SVE-3 with the exception of

MP-SVE-10S. At 7-8 ft bls, the methane concentrations adjacent to the SVE-3 were also

reduced significantly. At both depth intervals, it was possible to delineate an area of mitigation.

The extent of this area is generally slightly greater than the ROI as estimated from the vacuum

response data alone.

The test on SVE-3 test also resulted in a decrease of benzene concentrations at depth 2-3 ft bls

and 7-8 ft bls for most soil gas monitoring points located within the ROI (Plates 1 and 2).

3.6 ICE Performance Data In addition to the SVE well wellhead vacuums and flowrates, the hourly and cumulative makeup

propane usage was calculated and plotted on Figure 16 for the ICE engines. Regression

equations are also presented on Figure 16 for estimation of makeup fuel usage during long-term

operation of SVE operation. The results are summarized below:

• During the test on SVE-5, the total propane usage was approximately 550 pounds, corresponding to 9 lbs/hour of propane usage;

• During the first test on SVE-4, the total propane usage was approximately 310 pounds, corresponding to 4.5 lbs/hour of propane usage; and

• During second test on SVE-4, test on SVE-6 and SVE-3, the total propane usage was approximately 950 pounds per test, corresponding to 22 lbs/hour of propane usage (for two ICE engines).

During each individual SVE test, SVE influent and effluent samples were taken from the

sampling ports of ICE influent and effluent (stack off-gas). One SVE influent sample was taken

two hours after the startup of each SVE test. At the end of each SVE test, one SVE influent and

one SVE effluent sample were taken from the ICE engine. Samples were sent to AccuTest for

analysis of VOCs using United States Environmental Protection Agency (USEPA) Method

TO-15 and for methane using USEPA Method TO-3. A summary of influent and effluent

concentrations for SVE Tests is presented in Table 3. In addition, the VOC concentrations of

ICE effluent (stack offgas) were monitored every two hours using a multigas meter (MultiRAE

Plus). As summarized in Table 2, the PID readings were zero for each ICE engine during the

pilot study.


Based upon the influent and effluent analytical results, the average methane destruction and

removal efficiency (DRE) was approximately 98.6 percent and the average benzene DRE was

approximately 99.6 percent.


5.0 CONCEPTUAL VAPOR MITIGATION PLAN This section discusses the rationale and objectives for the vapor mitigation plan, the conceptual

design, and schedule for implementation.

5.1 Rationale and Objectives The results of the previous soil vapor investigations identified that the shallow soil vapor

(i.e., less than 8 ft bls) at and near the intersection of Apollo Street, Bridgewater Street and

Norman Avenue contains methane and benzene at concentrations exceeding site-specific soil

vapor screening criteria. Supplemental soil vapor sampling, ambient air sampling, screening of

utility manholes and screening and sampling of indoor air have been conducted throughout this

area. The results of this work have continued to show that the soil vapor conditions attributable

to the free product plume are not impacting indoor air and subsurface utilities.

In conjunction with the supplement investigation work described above, a pilot-testing program

was also undertaken to evaluate the feasibility of using SVE and bioventing as possible

mitigation options. The results of the pilot testing indicate that that SVE can be effective for

mitigation of the soil vapor concentrations in this area, and sufficient data information has been

collected to proceed with design of a full-scale system. While the results of the investigation

work have continued to show that the soil vapor conditions attributable to the free product plume

are not impacting indoor air and subsurface utility manholes, it is still recommended to proceed

with design and implementation of a full-scale mitigation system as a proactive and protective

measure.

The goal of the mitigation system will be to reduce methane concentrations in the 2 to 3 ft bls

interval to less than 12,500 ppm and to reduce concentrations in the 7 – 8 ft bls interval to less

than 50,000 ppm. In addition, the goal is to reduce benzene to below 170,000 ppb in both the

2 to 3 and 7 to 8 ft bls intervals. As shown in the Figures 11 through 15, and Plate 1, this level of

mitigation has been achievable in the vicinity of the individual pilot test SVE wells during the

conduct of 72-hour tests at each well.

5.2 Proposed SVE System The SVE wells for the full-scale SVE system will be sized to achieve a wellhead vacuum of

approximately 16 in. w.c. with a flowrate of 30 cfm using a screen interval of 13-18 ft bls.

Based on the results of the first and second phases of the SVE pilot study and to achieve the

remedial goals, the conceptual layout of the full-scale system will consist of seven SVE wells

screened from 13 to 18 ft bls (four new SVE wells [SVE-7 to SVE-10] and three existing SVE

wells SVE-3, SVE-4 and SVE-6). The location of the proposed and existing SVE wells is shown

on Figure 17.

Each SVE well will be designed for a flow rate of 30 cfm and 16 in. w.c. for a total flow rate of

210 cfm. Based upon the vacuum response observed in the pilot test results, a minimum radius

of influence of approximately 90 to 120 feet is expected for each well as shown in Figure 17.

Also shown are the approximate areas where methane exceeds the mitigation goal at the 2 to 3

and 7 to 8 ft bls intervals. As described in the pilot test results, the effective radius of influence

(the area where the SVE resulted in reduced vapor concentrations) typically extended beyond

the 90 to 120 foot range. When operating in concert, it is anticipated that the effective radius

influence will be further enhanced such that the network of SVE wells shown in Figure 17 will

provide effective mitigation of soil vapor in the target area.

The SVE wells will be manifolded together to a common header that is routed to a centralized

vapor extraction and treatment system. A subsurface pre-cast concrete well vault will be

installed at each SVE well location. The well vault will house vacuum gauges, valve, sample

port and flow meter. The full-scale design process is currently underway. A design package is

being prepared for submission to the NYSDEC as well as for the New York City Department of

Transportation (NYCDOT).

The proposed location of the treatment system compound for blowers, piping, controls, and

associated off-gas treatment is being investigated and is dependent on property access issues and

space. Although the ICE achieved DREs of up to 99%, the thermal off-gas treatment alternatives

(ICE and thermal oxidation) are being further evaluated in the design process based upon the

completed pilot test results to ensure that the off-gas treatment satisfies the Division of Air

Resources (DAR-1) permissible discharge limits and is cost effective for long term operation.

5.3 Preliminary Implementation Schedule The following implementation schedule has been developed:

• Soil Vapor Mitigation Design – Ongoing through November 2007;

• Property Access and Permitting Process with NYC Agencies and NYSDEC – September 2007 through February 2008;

• Equipment Procurement – December 2007 through February 2008;

• Construction – February 2008 through June 2008;

• System Startup – August 2008.

The above schedule is preliminary and contingent upon property access and regulatory

approvals. If property access and regulatory approvals are obtained quicker it may possible

expedite the above process. In addition, once the SVE wells and piping are installed within the

public right of way and routed to the treatment location, it may be possible to expedite the startup

schedule by using a temporary ICE treatment system until construction the of final treatment

system compound is complete.

4.0 PHASE II PILOT TEST CONCLUSIONS As discussed in Section 1.0, the second phase of the pilot study addressed the design issues from

the first phase of the pilot study. The following conclusions were determined based upon an

evaluation of the data generated during the SVE pilot study.

• The vacuum response data indicates that a ROI of between 55 and 88 feet at 2-3 ft bls as well as between 92 and 120 feet at 7-8 ft bls can be achieved consistently under a wellhead vacuum of 14 to 17 in. w.c. and SVE flow rates of 26 to 35 cfm.

• The pre- and post-test soil vapor sampling results indicate the effective area of mitigation will not be equidistant in all directions. The extent of the mitigation area may extend slightly beyond the ROI as estimated solely from the vacuum response data.

• The pilot study results indicated that street utilities and existing building foundation had only a minimal short-circuiting impact on the effective ROI of the SVE wells that are screened at depth from 13 to 18 feet bls. The screen depth of 13 to 18 ft bls was confirmed to be more effective than a shallow screen interval of 7 to 8 ft bls.

• The average methane DRE was approximately 98.6 percent. The average benzene DRE was approximately 99.6 percent.

• While running two ICEs in parallel, the SVE wells removed an average of 3.5 lbs/hour of methane and 0.15 lbs/hour of VOCs.

• When running the two ICEs in parallel, the influent concentrations did decline significantly following test startup but then appeared to approach steady-state conditions by the end of the 72-hour testing period. Methane concentrations in the extracted vapor at startup and conclusion of the three two-engine tests were: 60,700 versus 19,900 ppmv at SVE-4; 173,000 versus 32,600 ppmV at SVE-6; and 151,000 versus 54,300 ppmV at SVE-3.

• Along with the reduction in the influent methane concentrations there was an increase in the make-up propane usage required to run the ICEs. The amount of propane usage in each test appeared to stabilize at approximately 22 lbs/hour by the end of each 72-hour two engine test.
