These plans were subsequently approved by the City, and I provided you with the record copy of all of the signed mitigation measures forms, along with all supporting documentation. The permit for the HVI Site Improvements project, however, was not issued. To reduce the construction impact (including reducing the construction duration) on the site and to our patients, revisions were made to the vehicular bridge to the parking structure. Further, the paving revisions to the existing site that were initially contemplated were also scaled back. Plans for the revised HVI Site Improvements project were submitted to the City on January 23, 2012 (under Plan Check 1459-2012). Since that time, comments from that initial plan check were responded to, and the plans were resubmitted to the City on March 14, 2012. You completed your plan check for the revised HVI Site Improvements project with no comments, except that you requested that a review of mitigation measures compliance be undertaken and that, based upon that review, revised/amended documentation in support of the revised HVI Site Improvements project be submitted for approval. On February 14, Peri Muretta and I met with you to discuss the required information to be provided to document mitigation measures' compliance for the HVI Site Improvements project, as revised. The underlying plans, which include notes documenting compliance with some of the mitigation measures have not changed, nor have the plans themselves (including civil, erosion control, landscape, etc.). changed in a manner that would alter the determination of compliance that was completed for the original HVI Site Improvements project. Finally, most of the base technical studies, including traffic, hydrology, geology, soils corrosivity, etc., did not require amendment to reflect the revised HVI Site Improvements project. Therefore, the existing mitigation measures signoffs are valid. However, amendments were required to the approved Storm Water Pollution Prevention Plan and the approved Water Quality Management Plan to reflect the HIV Site Improvements project, as revised. A detailed discussion of the revisions to those documents is provided below. In addition to the information provided below, the accompanying plans/documents are also provided.

MM 62: A study of the concentration of potential hazardous constituents shall be conducted prior to initiation of the project to characterize the wastewater and any risk it may pose to human health prior to development. A stormwater pollution prevention plan shall be developed to reduce the risk of the transport of hazardous constituents from the site. The Hospital shall apply for coverage under the State Water Resources Control Board's General Permit for Storm Water Discharges Associated with Construction Activity and shall comply with all the provisions of the permit, including, but not limited to, the development of the SWPPP, the development and implementation of Best Management Practices, implementation of erosion control measures, the monitoring program requirements, and post construction monitoring of the system. Compliance: Halladay & Mim Mack prepared a Storm Water Pollution Prevention Plan documenting compliance with Mitigation Measure # 62. The SWPPP was approved by the City during the initial plan check process. Based on the revised HVl Site Improvements project, the previously approved SWPPP has been amended. Minor amendments to the SWPPP were necessitated based on the revised site plan for the HVI Site Improvements project. Additionally, amendments to the SWPPP were made to respond to requirements contained in the new RWQCB's General Construction Permit. While there are several changes that have been made to the SWPPP, these amendments are technical in nature, and do not substantively affect the SWPPP. A section -by -section summary of the amendments to the SWPPP is provided below: • Section 100 - SWPPP Certification and Approval - Reassignment of QSD and LRP - Addition of Section to provide Permit Registration Documents - Addition of Section on SWPPP Availability and Implementation • Section 200 - SWPPP Amendments Update to SWPPP Amendment Certification and Approval and Amendment Log sections (with corresponding Appendices provided) Provision of new sections to several components of Section 200 (including: Retention of Records, Required Non -Compliance Reporting, Annual Report, Changes to Permit Report and Notice of Termination) • Section 300 - Introduction and Project Description - Revision to project description Update to construction site estimates Revision to project schedule/water pollution control schedule Provision of new sections to several components of Section 300 (including: Soils, Slopes, Vegetation and Current Drainage Patterns; Stormwater Run-on from Offsite Areas; and Findings of the Construction Site Risk Determination) • Section 400 - References (provision of references to new General Construction Permit) Page 2 • • • Rosalinh Ung March 28, 2012 • Section 500 - Body of SWPPP - Update of various subsections to reflect new General Construction Permit (including: Water Pollution Control Plans, Operation/Maintenance after Project Completion and Other Plans/Permits) - Addition of new component to subsection "Construction BMP Maintenance, Inspection, Repair" to add "...and Rain Event Action Plan (REAP)" • Section 600 - Monitoring Program and Reports (provision of references to new Genera Construction Permit added to Section 600) • SWPPP Appendices Revision to existing Appendices to reflect SWPPP document changes, General Construction Permit updates and HVI Site Improvements revisions (Appendices A,G,FJand K) Provision of new Appendices to reflect new General Construction Permit (including: Appendix Q [SWPPP Amendments: Amendment Descriptions Certifications and Amendment Log]; Appendix R [Site Specific Rain Event Action Plan (REAP); and, Appendix S [Annual Reports]) 2. MM 12: Upon completion of final building construction plans, and prior to the issuance of a grading permit for each phase of development, the Project Sponsor shall ensure that site hydrological analyses are conducted to verify that existing drainage facilities are adequate. The applicant shall submit a report to the City of Newport Beach Building Department for approval, verifying the adequacy of the proposed facilities and documenting measures for the control of siltation and of erosive runoff velocities. Compliance: Halladay & Mim Mack prepared a Preliminary Hydrology Study and documenting compliance with Mitigation Measure # 12. Halladay & Mim Mack also prepared a WQMP for the project. The Hydrology Study did not require amendment, as the changes to the HVI Site Improvements project did not affect the overall drainage pattern of the site and resulted in very minor changes to the project's drainage areas (0.02 acres). There are, however, several revisions that have been made to the approved WQMP. These changes are minor in nature and were necessitated by the revisions to the HVI Site Improvements project's site plan. The complete revised WQMP is enclosed for your records, and the specific revisions are identified as follows: • Addition of a paragraph to the Owner's Certification page describing the reason for the amendment • Revision to project description in Section II • Revision to construction site estimates in Section III • Addition of cut sheets and filtration media description (for Kleenspout Filtration Vault) in Section VI • Revision to Attachment A (Notice of Transfer) to be specific to project Page 3 • • Rosalinh Ung March 28, 2012 • Revision to WQMP Site Plan based on current construction layout • Revisions to page numbers and WQMP document date Please let me know if you have any comments or questions on Hoag Hospital's compliance with the documentation submitted in support of the revised HVI Site Improvements project for satisfaction of the mitigation measures identified above.

Based on the permitting of separate components of the project, and its review by the Office of Statewide Health Planning and Development (OSHPD), the overall applicability matrix was amended (and subsequently approved by you on December 6, 2010) to reflect two separate OSHPD submittals for mitigation compliance review by the City of Newport Beach, as well as one submittal to the City of Newport Beach for permitting and mitigation compliance review. The first of the OHSPD submittals, OSHPD Package One, included a hybrid OR, staff area, pre-op/PACU and Cath Labs. Documentation was submitted to (and subsequently approved by) the City for compliance with OSHPD Package One, which was permitted by OSHPD on May 31, 2011. The second OSHPD submittal, OSHPD Package Two, was submitted to OSHPD for initial plan check on July 8, 2011, and is currently still under review by OSHPD. The OSHPD Package Two project includes upgrades to the One South interior. Mitigation measure compliance documentation is being submitted separately to the City for the OSHPD Package Two project. When the December 6, 2011 matrix was approved, it included minor building facade improvements, in addition to site improvements, as, part of the City submittal.

Mitigation Measure 110: The Project Sponsor shall ensure that low emission mobile and stationary equipment is utilized during construction, and low sulfur fuel is utilized in stationary equipment, when available. Evidence of this fact shall be provided to the City of Newport Beach prior to issuance of any grading or building permit. Mitigation Measure 3.3-1: During construction of the Project, the Applicant and its Contractors shall be required to comply with regional rules established by the South Coast Air Quality Management District (SCAQMD), which assist in reducing short-term air pollutant emissions. The SCAQMD's Rule 403 requires that fugitive dust be controlled with best available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. Two options are presented in Rule 403: monitoring of particulate concentrations or active control. Monitoring involves a sampling network around the project with no additional control measures unless specified concentrations are exceeded. The active control option does not require any monitoring, but requires that a list of measures be implemented starting with the first day of construction. Rule 403 requires that "No person shall conduct active operations without utilizing the best available control measures included in Table 1 of this Rule to minimize fugitive dust emissions from each fugitive dust source type within the active operation." The measures from Table 1 of Rule 403 are presented in this SEIR as Table A. It is required that all applicable and feasible measures in Table A are implemented. At this time, specific construction projects are not specified so it is unknown which measures will be applicable. All applicable and feasible control measures for each source category used during construction shall be implemented. Prior to permit issuance, the Applicant shall submit a list of applicable measures that will be implemented along with a list of inapplicable measures that will not be implemented for the specific construction project. Rule 403 requires that "Large Projects" implement additional measures. A Large Project is defined as "any active operations on property which contains 50 or more acres of disturbed surface area, or any earthmoving operation with a daily earthmoving or throughput volume of 5,000 cubic yards for more than three times during the most recent 365 day period." Grading of the project is not considered a Large Project under Rule 403. However, the project shall implement all applicable and feasible measures specified in Table 2 (presented in this SEIR as Table B) to the greatest extent possible. This results in a higher reduction of fugitive dust emissions than would be achieved through complying solely with Table A. At this time, specific construction projects are not specified so it is unknown which measures will be feasible. Prior to permit issuance, the Applicant shall submit a list of applicable measures that will be implemented for the specific construction project along with justification for the infeasibility finding. Rule 403 also requires that the construction activities "shall not cause or allow PM10 levels to exceed 50 micrograms per cubic meter when determined by simultaneous sampling, as the difference between upwind and downwind sample." Projects that cannot meet this performance standard are required to implement the applicable actions specified in Table 3 of Rule 403 (presented in this SEIR as Table C). Rule 403 requires that that the project shall not "allow track -out to extend 25 feet or more in cumulative length from the point of origin from an active operation." All track -out from an active Page 5 • • Hoag Memorial Hospital Presbyterian Master Plan Update Final Supplemental Environmental Impact Report Mitigation Measures, Cont. operation is required to be removed at the conclusion of each workday or evening shift. Any active operation with a disturbed surface area of five or more acres or with a daily import or export of 100 cubic yards or more of bulk materials must use at least one of the measures listed in Table D at each vehicle egress from the site to a paved public road.

The SCAQMD's Rule 403 requires that fugitive dust be controlled with best available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. Two options are presented in Rule 403: monitoring of particulate concentrations or active control. Monitoring involves a sampling network around the project with no additional control measures unless specified concentrations are exceeded. The active control option does not require any monitoring, but requires that a list of measures be implemented starting with the first day of construction. Rule 403 requires that "No person shall conduct active operations without utilizing the best available control measures included in Table 1 of this Rule to minimize fugitive dust emissions from each fugitive dust source type within the active operation." The measures from Table 1 of Rule 403 are presented in this SEIR as Table A. It is required that all applicable and feasible measures in Table A are implemented. At this time, specific construction projects are not specified so it is unknown which measures will be applicable. All applicable and feasible control measures for each source category used during construction shall be implemented. Prior to permit issuance, the Applicant shall submit a list of applicable measures that will be implemented along with a list of inapplicable measures that will not be implemented for the specific construction project. Rule 403 requires that "Large Projects" implement additional measures. A Large Project is defined as "any active operations on property which contains 50 or more acres of disturbed surface area, or any earthmoving operation with a daily earthmoving or throughput volume of 5,000 cubic yards for more than three times during the most recent 365 day period." Grading of the project is not considered a Large Project under Rule 403. However, the project shall implement all applicable and feasible measures specified in Table 2 (presented in this SEIR as Table B) to the greatest extent possible. This results in a higher reduction of fugitive dust emissions than would be achieved through complying solely with Table A. At this time, specific construction projects are not specified so it is unknown which measures will be feasible. Prior to permit issuance, the Applicant shall submit a list of applicable measures that will be implemented for the specific construction project along with justification for the infeasibility finding. Rule 403 also requires that the construction activities "shall not cause or allow PM10 levels to exceed 50 micrograms per cubic meter when determined by simultaneous sampling, as the difference between upwind and downwind sample." Projects that cannot meet this "performance standard are required to implement the applicable actions specified in Table 3 of Rule 403 (presented in this SEIR as Table C). Rule 403 requires that that the project shall not "allow track -out to extend 25 feet or more in cumulative length from the point of origin from an active operation." All track -out from an active operation is required to be removed at the conclusion of each workday or evening shift. Any active operation with a disturbed surface area of five or more acres or with a daily import or export of 100 cubic yards or more of bulk materials must use at least one of the measures listed in Table D at each vehicle egress from the site to a paved public road.

(GeoTek) is pleased to present herein our response to review comments dated July 27, 2011 by the City of Newport Beach reviewer, Mr. Ken Bagahi. Review comments were provided to GeoTek by the project architect. For clarity and ease of review, each of the reviewer's comments is reiterated below and is followed by this firm's response. Item No. I "Page 2. Report is based on previous findings by Crandall and MACTEC. Please provide relevant portions of the previous reports utilized in this study including boring locations, logs and relevant lab data." Response Relevant portions of the referenced reports are included in Appendix A of this response report. Item No. 2 "Page 5. Passive earth pressures and coefficient of friction exceed code values. Please provide supporting computations." GEOTECHNICAL I ENVIRONMENTAL I MATERIALS • • • HOAG MEMORIAL HOSPITAL PRESBYTERIAN Project No. 0775-CR3 Response to City Geotechnical Review Comments September 13, 2011 Hoag Hospital HVI Entry Improvements, Newport Beach, Orange County, California Page 2 Response Based on the information from the referenced reports (LeRoy Crandall, 1971; MACTEC, 2006) a friction angle of 29 degrees and a moist unit weight of 105 pcf were selected to represent the on -site formational materials. Using those values the following can be calculated: Rankine passive coefficient (Kp) = 2.882; Passive resistance = (2.882) x (105) = 302.6 psf/ft, USE 250; Maximum passive resistance = 15 x 250 = 3,750 psf/ft; Coefficient of Friction = tan-1(29)/1.5 = 0.37, USE 0.35. Item No.3 "Pages 6 and 7. Please provide computations for recommended earthquake forces for active and restrained cases. Please note that Section 1601.1 deals with static loading. Seismic loading is discussed in Section 1803.5.12." Response The earthquake forces were computed for the active condition using the Mononobe- Okabe/Seed-Whitman procedure using Kh=0.15. Therefore, the additional seismic increment, iPae, equals 0.75 x (Kh) x (y) x H2 = 0.75 x (0.15) x (105) x H2 = 11.8 H2, use 12 H2. Similarly, using Wood (1973) for restrained condition, APae, equals (Kh) x (y) x H2 = (0.15) x (105) x H2 = 16.5 H2, use 17 H2. Note this value was incorrectly reported as 32H2 in the referenced report by GeoTek (20 I I ). Item No. 4 "Page 6. Wall backfill. Please provide separation fabric between crushed rock and on -site soil backfill." Response The first paragraph under the heading "Wall Backfill and Drainage" on page 6 of the referenced report (GeoTek, 201 I) has been revised as indicated below. The added text relevant to the reviewer's request is underlined. The onsite soils characterized as having "very low" to "low" expansion potential may be used for backfill provided they are screened of greater than 3-inch size gravels. Wall backfill should include a minimum one foot wide section of 3/4 to I -inch clean crushed rock (or approved equivalent). The rock should be placed immediately adjacent to the back of wall and extend up from the back drain to within approximately 12 inches of finish grade. A geotextile fabric, such as Mirafi 140N (or approved equivalent), should be placed between the crushed rock and the backfill materials. The upper 12 inches should consist of compacted onsite materials. Presence of other materials might necessitate revision to the parameters provided and modification of GEOTEK • • • HOAG MEMORIAL HOSPITAL PRESBYTERIAN Project No. 0775-CR3 Response to City Geotechnical Review Comments September 13, 2011 Hoag Hospital HVI Entry Improvements, Newport Beach, Orange County, California Page 3 wall designs. The backfill materials should be placed in lifts no greater than 8-inches in thickness and compacted to a minimum of 90% relative compaction in accordance with ASTM Test Method D 1557. Proper surface drainage needs to be provided and maintained. Item No. 5 "Page 7. Caisson Design. Please review Structural Plans Sheets S-2.01 and S3.02 and supporting computations for conformance with your recommendations and in particular provide (a) passive earth pressure for caissons in close proximity of the basement wall and resulting surcharge loading and its distribution on the wall (b) in caisson supported footings, provide footing surcharge (vertical and lateral) on caissons below (c) vertical and lateral bearing for footings located in the active failure plane behind the caissons (d) provide computations for the axial capacity of the belled caissons (e) expected differential settlement between the wall supported on caissons and wall supported on footings and (f) provide subsurface profile on a typical section. Response GeoTek's responses to the reviewer's comments 5(a) through 5(f) are presented below. (a) It is this firm's understanding that the passive resistance for those caissons near the wall (i.e. Details L 13, A I , A5 and Al 3 on Sheet S3.02 of the structural plans) will be provided by the concrete keyways depicted on the details. (b) In situations where two rows of caissons are utilized (i.e. Section L I on Sheet 3.02), GeoTek suggests deepening the upper caisson below a 45 degree projected from the bottom portion of the caisson bell located furthest away from the wall in order to reduce the surcharge on the lower, adjacent caisson. (c) Since the lateral resistance is being provided by the keyway on the conventional footing, it is not anticipated that an active failure plane will develop behind the caissons. (d) See attached computations for the axial capacity of caissons in Appendix B. (e) Assuming an allowable bearing of 6000 psf for the caissons and 2000 psf for the continuous footings, a differential settlement of approximately I -inch over 40 horizontal feet has been estimated. (f) The subsurface materials anticipated to be encountered at the site consist primarily of Pleistocene -aged Terrace Deposits and possibly some fill materials. The Terrace Deposits are generally massive and have a typical near -surface weathered profile (approximately 2-3 feet thick). Detail AS from Sheet S3.02 of the structural plans has been modified to depict the anticipated subsurface profile on a typical section. See below.

Please provide recommendations for caisson installation including caving, temporary shoring maximum diameter of the bell, minimum embedment required, and bell clean out and inspection. Response The diameter of the caisson bell should not exceed three and one-half (3 V2) times that of the caisson. The caisson excavation bottoms should be cleared of loose soil at the completion of drilling and reaming. Temporary casing of the shafts and shoring of the bells must be provided to allow for personnel to clean and observe the excavations. Prior to concrete or steel placement, the caisson excavations should be observed a by GeoTek representative to confirm the anticipated geologic conditions, depth, and loose soil removal. Caissons should be embedded a minimum of two (2) feet into dense formational material. Concrete placed for the caissons should not be allowed to fall more than four (4) feet. A tremie tube should be used to place concrete deeper than four (4) feet. Excavations should be free of loose soil at the time of concrete placement. Item No. 7 "Page 7. Sulfate. Please revise to read Type V cement." Response The paragraph under the heading "Sulfate and Corrosion Testing" on page 9 of the referenced report (GeoTek, 201 1) has been revised as indicated below. The revised wording relevant to the reviewer's request is underlined. G EOTEK • HOAG MEMORIAL HOSPITAL PRESBYTERIAN Project No. 0775-CR3 Response to City Geotechnical Review Comments September 13, 201 1 Hoag Hospital HVI Entry Improvements, Newport Beach, Orange County, California Page 5 Concrete utilizing Type V cement with a maximum water to cement ratio of 0.45 and minimum strength of 4,500 psi is recommended for the site, due to the site's proximity to the ocean and industry standards used in the area. The MACTEC (2006) report includes a "Soil Corrosivity Study" performed by M.J. Schiff and Associates, Inc. The project design team should incorporate the recommendations presented in the "Soil Corrosivity Study" into the proposed improvements, as appropriate. Item No. 8 "Please provide a statement that the proposed construction is feasible and would not adversely impact adjoining improvements." Response Provided that the recommendations presented herein and this firm's referenced report are incorporated into the design and construction, it is our opinion that the proposed construction is feasible and is not anticipated to adversely impact adjoining improvements. Geotechnical observation and testing should be performed during construction. If field conditions differ from those anticipated based on the referenced field investigative work and laboratory test results, additional recommendations may be necessary. Item No. 9 "Review. Please review and comment upon the geotechnical aspects of the grading and foundation plans and verify that the plans are in conformance with the geotechnical recommendations in the referenced report. Please include a copy of the plans with your response." Response GeoTek has reviewed the civil plans titled "HVI Entry Improvements" by Halladay and Mimmack, Inc. and the structural plans by TMAD Taylor Gaines, both with latest revision dates of September 13, 201 1, and found them to be in general conformance with the geotechnical recommendations presented in this and the referenced report (GeoTek, 201 1). It is this firm's understanding that the project architect will submit copies of the plans with this response.

(GeoTek) is providing this Supplemental Geotechnical Report for currently proposed improvements at the subject site. This report presents 2010 CBC seismic design parameters, foundation, flatwork and pavement design recommendations, and earthwork considerations. The referenced reports by LeRoy Crandall and Associates (1971) and MACTEC (2006) provide preliminary geotechnical information for the site area completed by their respective firms and are the primary basis for this firm's recommendations. This report presents a statement of geotechnical consultant of record for the currently proposed improvements. Upon review of the referenced reports, GeoTek generally concurs with the findings, conclusions and recommendations provided. The recommendations provided are considered suitable from a geotechnical perspective, unless otherwise superseded herein or in future reports by this firm. GeoTek herein assumes the responsibility as geotechnical consultant of record henceforth for the subject improvements. SITE DESCRIPTION EXISTING CONDITIONS The project site, Hoag Hospital — Heart and Vascular Institute (HVI), is located at One Hoag Drive in the City of Newport Beach, Orange County, California. The area of currently proposed site improvements is located within and adjacent to an existing driveway area between an existing multi -story parking structure to the south, and an existing hospital building *Revised 7/20/201 I to correct a typographical error on page 10. GEOTECHNICAL I ENVIRONMENTAL MATERIALS HbAG MEMORIAL HOSPITAL PRESBYTERIAN Supplemental Geotechnical Evaluation, Hoag Hospital HVI Entry Improvements Newport Beach, Orange County. California Project No. 0775-CR3 June 14, 201 1 * Page 2 structure (HVl) to the north. It is not precisely known the age of the existing site improvements, but the parking. structure and related improvements were likely constructed in the early 1970's, and the existing HVI building is on the order of roughly 20± years old. Based on review of the referenced reports by LeRoy Crandall & Associates (1971) and MACTEC (2006), and our recent site reconnaissance, the area of currently proposed improvements is likely underlain by some engineered fill and/or Pleistocene age marine terrace deposits. Based on the descriptions of materials presented in the boring logs in the referenced reports, the terrace deposits are predominantly comprised of silty sand materials, with some silty clay interbeds. No report of previous grading activities for the area of currently proposed improvements was provided or reviewed by this firm. However, based on field observations and our review of the referenced reports, the existing site fills are likely relatively shallow (pre-existing and existing site grades are similar, and previously described site conditions did not appear to necessitate deep over -excavations prior to site development). No obvious signs of settlement, distress, or slope instabilities were noted during our site reconnaissance, nor have such occurrences been reported to us for the subject site area. CURRENTLY PROPOSED DEVELOPMENT Currently proposed improvements include the widening and realigning of a portion of the existing site driveway, associated landscape and hardscape improvements. The proposed driveway widening will require the construction of a retaining wall along an existing 5-20± foot high I'/:1 (h:v) gradient slope that descends from the HVI drive area to the existing parking structure. The proposed retaining wall is on the order of roughly 150 lineal feet and is understood to range from approximately 2 to 12± feet in height. Based on conversations with the project team, and review of preliminary site plans, it is our understanding that the proposed retaining wall will be partially founded on caissons in order to avoid surcharging the existing subterranean parking garage wall. The entry drive will likely be reconstructed with Portland cement concrete (PCC). EARTHWORK CONSIDERATIONS Earthwork associated with the currently proposed site improvements will likely include foundation excavations, retaining wall backfill, and pavement and flatwork subgrade preparation. All earthwork should be performed in accordance with the applicable grading ordinances of the City of Newport Beach, County of Orange, the 2010 California Building Code (CBC), and recommendations contained in this report. *Revised 7/20/20I I to correct a typographical error on page 10 ..-Cr"--, GEOTEK HbAG MEMORIAL HOSPITAL PRESBYTERIAN Supplemental Geotechnical Evaluation, Hoag Hospital HVI Entry Improvements Newport Beach, Orange County, California Site Clearing Project No. 0775-CR3 June 14, 2011* Page 3 Proposed site improvement areas should be cleared of existing improvements, vegetation, roots, trash, and debris prior to earthwork activities. These materials should be properly disposed of offsite. Grading Based the information in the referenced reports and our recent site observations, we recommend that the existing site area be scarified to a minimum depth of 12 inches, moisture conditioned to at or above optimum moisture content, and then re -compacted to at least 90% relative compaction (as determined per ASTM D 1557) subsequent to removals of any existing site improvements. Reprocessing should extend to a depth where soils are sufficiently compacted and have moisture contents of optimum or above. The depth of reprocessing may need to be increased beyond a depth of 12 inches based on the results of the field density testing, moisture content testing, or observations of the soils during the construction process. Also, additional removals beyond the 12 inch scarification depth may be required in the locally weathered areas in order to expose dense/firm engineered fill soils or competent native materials, prior to placement of additional engineered fill materials. Street, parking, driveway and flatwork areas will need to be similarly reprocessed prior to placement of additional fill materials. Engineered fill materials should be evenly spread, moisture conditioned, processed and compacted in thin lifts, six (6) to eight (8) inches in compacted thickness, to obtain a uniformly dense layer. The fill should be placed and compacted on a nearly horizontal plane, unless otherwise found acceptable by our representative. A representative of GeoTek should perform observation and testing services during the grading procedures. If import soils are proposed for use as engineered fill, GeoTek should observe, test and approve prior to importing in order to confirm that these materials are suitable for the subject site. Underground Utility Construction Utility trench excavations should be shored or laid back in accordance with applicable CAUOSHA standards. All utility trench and/or irrigation line backfill should be compacted to at least 90% relative compaction (as determined per ASTM D 1557). Under -slab trenches should also be *Revised 7/20/2011 to correct a typographical error on page 10 GEOTEK HbAG MEMORIAL HOSPITAL PRESBYTERIAN Supplemental Geotechnical Evaluation, Hoag Hospital HVI Entry Improvements Newport Beach, Orange County, California Project No. 0775-CR3 June 14, 201 1 * Page 4 compacted to project specifications. On -site materials may not be suitable for use as bedding material, but should be suitable as backfill provided it is placed in accordance with recommendations provided herein. Compaction should be achieved with a mechanical compaction device. Jetting of native soils will not be acceptable. If backfill soils have dried out, they should be thoroughly moisture conditioned prior to placement in trenches. SEISMIC DESIGN CONSIDERATIONS 2010 CBC Criteria The site is located at approximately 33.6236 Latitude and - 117.929199 Longitude. Site spectral accelerations (Ss and Si), for 0.2 and 1.0 second periods for a Class "D" site, were determined from the USGS Website, Earthquake Hazards Program, Interpolated Probabilistic Ground Motion for the Conterminous 48 States by Latitude/Longitude, 2009 Data. The results are presented in the following table: SITE SEISMIC PARAMETERS Mapped 0.2 sec Period Spectral Acceleration, Ss 1.827 Mapped 1.0 sec Period Spectral Acceleration, S I 0.684g Site Coefficient for Site Class "D", Fa 1.0 Site Coefficient for Site Class "D", Fv 1.5 Maximum Considered Earthquake Spectral Response Acceleration Parameter at 0.2 Second, SMS 1827g Maximum Considered Earthquake Spectral Response Acceleration Parameter at I second, SM I 1,026g Design Spectral Response Acceleration for Parameter for 0.2 Second, SDS 1218g Design Spectral Response Acceleration for Parameter 1.0 Second, SD I 0.684g RETAINING WALL DESIGN AND CONSTRUCTION Foundation design criteria for a conventionally reinforced foundation system, in general conformance with the 2010 CBC, are presented below. These are typical design criteria and are not intended to supersede the design by the structural engineer. Based on the test results of Expansion Index testing and descriptions presented in the referenced reports the onsite soils near subgrade may generally be classified having potential expansion ranging from "very low" to "low" in general accordance with ASTM D 4829. *Revised 7/20/2011 to correct a typographical error on page 10 GEOTEK HOAG MEMORIAL HOSPITAL PRESBYTERIAN Supplemental Geotechnical Evaluation, Hoag Hospital HVI Entry Improvements Newport Beach, Orange County, California Project No. 0775-CR3 June 14, 2011* Page 5 The following criteria for design of foundations should be implemented into design. General Design Criteria Recommendations presented herein apply to typical masonry or concrete vertical retaining walls to a maximum height of up to 13 feet. Additional review and recommendations should be requested for higher walls. These are typical design criteria and are not intended to supersede the design by the structural engineer Retaining wall foundations embedded a minimum of 24 inches into engineered fill or dense formational materials should be designed using an allowable bearing capacity of 2,000 psf (minimum two feet embedment below lowest adjacent grade). The passive earth pressure may be computed as an equivalent fluid having a density of 250 psf per foot of depth, to a maximum earth pressure of 3,750 psf. A coefficient of friction between soil and concrete of 0.35 may be used. The upper one foot of soil below the adjacent grade should not be used in calculating passive pressure. Passive pressure and frictional resistance may be combined as allowed by code. Passive resistance for sloping conditions should be reduced by 50 percent for those elements near the slope face. The above values may be increased as allowed by Code to resist short-term transient loads (e.g. seismic and wind loads). Continuous footings should have a minimum reinforcement consisting of four (4) No. 4 reinforcing bars, two (2) top and two (2) bottom. Structural concerns may govern and are under the purview of the structural engineer. Cantilevered Walls The recommendations presented below are for cantilevered retaining walls up to 13 feet high. Active earth pressure may be used for retaining wall design, provided the top of the wall is not restrained from minor deflections. An equivalent fluid pressure approach may be used to compute the horizontal pressure against the wall. Appropriate fluid unit weights are given below for specific slope gradients of the retained material. These do not include other superimposed loading conditions such as traffic, structures, seismic events, or adverse geologic conditions. *Revised 7/20/2011 to correct a typographical error on page 10 „CT_.

Backfill zone includes area between back of wall to plane (I: I, h:v) up from back of wall foundation to ground surface. Additional lateral forces can be induced on retaining walls during an earthquake. For level backfill and a Site Class "D", the minimum earthquake -induced force (Feq) should be 12H2 (Ibs/linear foot of wall). This force can be assumed to act at a distance of 0.6H above the base of the wall, where "H" is the height of the retaining wall measured from the base of the footing (in feet). Wall Backfill and Drainage The onsite soils characterized as having "very low" to "low" expansion potential may be used for backfill provided they are screened of greater than 3-inch size gravels. Wall backfill should include a minimum one foot wide section of 3/4 to 1-inch clean crushed rock (or approved equivalent). The rock should be placed immediately adjacent to the back of wall and extend up from the back drain to within approximately 12 inches of finish grade. The upper 12 inches should consist of compacted onsite materials. Presence of other materials might necessitate revision to the parameters provided and modification of wall designs. The backfill materials should be placed in lifts no greater than 8-inches in thickness and compacted to a minimum of 90% relative compaction in accordance with ASTM Test Method D 1557. Proper surface drainage needs to be provided and maintained. Retaining walls should be provided with an adequate pipe and gravel back drain system to prevent build up of hydrostatic pressures. Backdrains should consist of a 4-inch diameter perforated collector pipe embedded in a minimum of one cubic foot per lineal foot of 3/4 to one inch clean crushed rock or equivalent, wrapped in filter fabric. The drain system should be connected to a suitable outlet. A minimum of two outlets should be provided for each drain section. Spacing between drain outlets should not exceed 100 feet. Waterproofing of site walls should be performed where moisture migration through the wall is undesirable. *Revised 7/20/201 I to correct a typographical error on page 10 „C-T, GEOTEK HOAG MEMORIAL HOSPITAL PRESBYTERIAN Supplemental Geotechnical Evaluation, Hoag Hospital HVI Entry Improvements Newport Beach, Orange County, California Restrained Retaining Walls Project No. 0775-CR3 June 14, 201 1* Page 7 Retaining walls that will be restrained prior to placing and compacting backfill material or that have reentrant or male corners, should be designed for an at -rest equivalent fluid pressure of 65 pcf, plus any applicable surcharge loading. For areas of male or reentrant corners, the restrained wall design should extend a minimum distance of twice the height of the wall laterally from the corner. Additional lateral forces can be induced on restrained walls during an earthquake. If required by Section 1610.1 of 2010 CBC, for level backfill and a Site Class "D", the minimum earthquake -induced force (Feq) should be 32H2 (lbs/linear foot of wall). This force can be assumed to act at a distance of 0.6H above the base of the wall, where "H" is the height of the retaining wall measured from the base of the footing(in feet). CAISSON DESIGN PARAMETERS GeoTek understands that caissons will be used to support the proposed retaining wall located near the existing parking structure, in order to not surcharge the existing structure. Design parameters for such a system are presented below. Proposed caissons can be designed to resist passive pressures of 500 psf per foot of depth to a maximum of 6,000 psf (dead plus live load), plus 1/3 increase for seismic (at least four feet embedment into competent natural ground). The per foot depth passive resistance values should be reduced by 50 percent for caissons founded on slope faces or near top of slopes. Passive pressures should be ignored in the upper five (5) feet for caissons located on slope faces or near the top of slopes or within the upper one (I) foot for caissons located on level areas. If caissons extend to depths below the toe of slope, no reduction in passive resistance is necessary for that portion of the caisson embedded below the toe of slope. The passive values presented incorporate "3-dimensional" effects. Thus, passive values should not be increased to account for an "effective width" beyond the actual width of the caissons. The 500 psf passive resistance and 6000 psf lateral capacity is applicable for caissons located a minimum distance of 8 diameters from the existing retaining wall. Caissons located a distance of 5 diameters from the wall should use 50 percent of those values; values for intermediate locations may be interpolated. In order to reduce the potential imposition of additional lateral loads on the wall, placement of caissons (that are subject to lateral loads) closer than 5 times the caisson diameter should be avoided. If passive resistance of the caissons and the wall key are combined, then the passive resistance of the caisson at the same elevations as the key should be ignored. *Revised 7/20/2011 to correct a typographical error on page 10 GEATEK HOAG MEMORIAL HOSPITAL PRESBYTERIAN Supplemental Geotechnical Evaluation, Hoag Hospital HVI Entry Improvements Newport Beach, Orange County, California Project No. 0775-CR3 June 14, 2011* Page 8 Caissons should not be spaced closer than 3 diameters, center -to -center. Caissons should be connected with a grade beam designed by the structural engineer. Friction along the bottom of the grade beam may be considered when evaluating lateral resisting forces. A coefficient of friction between soil and concrete of 0.35 may be used. Depth of fixity for caissons on the order of 2 to 3 feet in diameter can be approximated as 5 times the caisson diameter. Axial load capacity versus depth plots for 2 and 3 foot diameter caissons are attached as Plates I through 4. Other Design Considerations • Retaining wall foundation elements should be designed in accordance with building code setback requirements. • Passive earth pressure coefficients used in the design of retaining walls should consider descending slope conditions. Passive pressures should be reduced by one-half in the case of descending 2:1 (h:v) gradient slopes. • Retaining wall design should consider the additional surcharge loads from superjacent slopes and/or footings, where appropriate. • No backfill should be placed against concrete until minimum design strengths are evidenced by compression tests of cylinders. • The retaining wall footing excavations, backcuts, and backfill materials should by approved the project geotechnical engineer or their authorized representative. SULFATE AND CORROSION TESTING Type 5 concrete with a maximum water to cement ratio of 0.45 and minimum strength of 4,500 psi is recommended for the site, due to the site's proximity to the ocean and industry standards used in the area. The MACTEC (2006) report includes a "Soil Corrosivity Study" performed by M.). Schiff and Associates, Inc. The project design team should incorporate the recommendations presented in the "Soil Corrosivity Study" into the proposed improvements, as appropriate. *Revised 7/20/20I I to correct a typographical error on page 10 ,G.

The removal bottom should be scarified a minimum of 12 inches after over -excavation, and then re -compacted to project standards (see below). The subgrade soils may need to be allowed to dry out if overly moist or pumping. The recommended concrete pavement section provided below is based on the known site use (driveway area, with potential for heavy traffic loads). Performance of this pavement section will ultimately be based largely on construction methods and traffic loading, and subgrade performance. Asphaltic Concrete Pavement The recommended pavement section provided below is based on the laboratory testing of the subgrade soils and the resulting R-Value (41) by MACTEC (2006). Performance of this pavement section will ultimately be based largely on construction methods and traffic loading, and subgrade performance. The traffic index assumed for pavement design should be reviewed by a traffic/civil engineer. Additional testing may be necessary depending on exposed conditions during earthwork construction.

RESERVES THE RIGHT TO REVIEW SUCH CONDITIONS AND TO MODIFY, AS APPROPRIATE, THE ASSESSMENTS AND ANY CONCLUSIONS PROVIDED IN THIS REPORT. • • EXECUTIVE SIJMMARY At the request of Hoag Memorial Hospital Presbyterian ("Client"), GeoScience Analytical, Inc. has evaluated soil corrosivity on property proposed on property proposed for Site Development (Upper Campus) located immediately west of Hoag Drive and within the main campus of Hoag Memorial Hospital Presbyterian (see Figure 1). The subject report addresses the requirements of Mitigation Measures 6, 7 & 8 (Appendix III) of the Hoag Upper Campus HVI Entry Improvements Project as adopted by the City of Newport Beach. SI1 E HISTORY While the Lower Campus property has been known to contain methane and hydrogen sulfide in the near surface soils for several decades, the Upper Campus is void of these contaminants. Groundwater seepage on a part of the Lower Campus north of the intersection of Hoag Drive and West Coast Highway also occurs. The source of the water is thought to be groundwater seepage along the contact between the terrace materials which overlie the Monterey Formation bedrock. The Monterey Formation is most likely the source of the methane and hydrogen sulfide gases which are being produced from various sand horizons. Hydrogen sulfide is acidic and in the presence of oxygen may be converted to sulfuric acid. In 1976, three gas extraction wells were installed along West Coast Highway on the Lower Campus. The gas from these wells currently is extracted with a suction pump system and flows through a series of pipes into a burner or to a gas fired boiler. In 1989, two of the extraction wells were relocated to allow for the widening of West Coast Highway. The existing gas extraction system serves as partial mitigation to a potentially hazardous situation for the subject property and, to a much larger extent, the surrounding • • • public and private properties offsite. In the absence of the gas extraction system, potentially hazardous and noxious concentrations of hydrogen sulfide and methane would vent naturally into the atmosphere and structures. The chemically reactive hydrogen sulfide could additionally create elevated concentrations of corrosive chemical agents which may negatively impact site development. No evidence has been found for the presence of hazardous substances with respect to corrosive soils (pH<2 or >12.5: Title 22 of the California Administrative Code). Soils do not require design mitigation to prevent deleterious effects to construction materials (see Mitigation Measure 7). Soil corrosivity (pH) ranged from 8.48 to 8.70. With respect to soil corrosivity, no limitations exist which will render the site unsuitable for development with adequate mitigation for construction materials. • • SUMMARY At the request of Hoag Memorial Hospital Presbyterian, GeoScience Analytical, Inc. has conducted a Phase II Environmental Audit on property proposed for Site Development (Upper Campus) located immediately west of Hoag Drive on the main campus of Hoag Memorial Hospital Presbyterian (see Figure 1). This study has been undertaken to satisfy mitigation measures 6, 7 and 8 (see Appendix III) for the Upper Campus HVI Entry Improvements Project which require the completion of a soil sampling and monitoring program which shall address the presence of corrosive soils. Conditions imposed by mitigation measures 6, 7 and 8 have been addressed and no hazardous substances have been identified based on corrosivity. A review of appropriate construction materials is not required based on the corrosivity assessment. A previous study, "Preliminary Geochemical Site Evaluation of Existing Relief Wells, Gaseous Flare, Soil, Water and Air on a Portion of Hoag Memorial Hospital Presbyterian Property Newport Beach, California (22 April 1992)" which contains related information and pertinent data is attached hereto as Appendix II. Mitigation measure 8 does not apply based on the degree of corrosivity identified. One (1) soil boring was advanced to a depth of twenty (20') feet below existing grade in the developed portion of the Upper Campus on property proposed for Site Development (Upper Campus) located immediately west of Hoag Drive on the main campus of Hoag Memorial Hospital Presbyterian (see Figure 2). The subject report addresses the requirements of Mitigation Measures 6, 7 & 8 (Appendix III) for the Upper Campus HVI Entry Improvements Project as adopted by the City of Newport Beach. Soil samples were collected at depths of 10.0' and 20.0'. Hoag Memorial Hospital Presbyterian, as Client, placed no constraints on the Contractor, nor did it suggest any interpretation of the data which were generated prior to completion of this report. The pH of soil samples ranged from a low of 8.48 to a high of 8.70. Corrosivity at the subject site does not, therefore, classify the soil as containing hazardous materials or excess residual hazardous substances. o • 10 • • FINDINGS GeoScience Analytical, Inc. has conducted a Phase II evaluation of a portion of the Upper Campus of Hoag Memorial Hospital Presbyterian. The property evaluated is proposed for Site Development (Upper Campus) located immediately west of Hoag Drive within the main campus of Hoag Memorial Hospital Presbyterian (see Figure 1). One (1) boring was advanced to a depth of twenty (20') feet below existing grade and soil samples were taken for geochemical characterization of the site with respect to corrosivity. There was no evidence found for the presence of corrosive soils (pH<2 or>12.5) as defined by Title 22 of the California Administrative Code. No hazardous materials or excess residual hazardous substances have been identified under the scope of the subject investigation. 11 o • • ANALYTICAL PROTOCOL Laboratory Analyses Corrosivity of Soil (pH) EPA method 9045C was used to quantify the pH (corrosivity) of soil samples. 12 • • • RESULTS AND DISCUSSION A previous geochemical investigation has been completed by GeoScience Analytical, Inc. covering the undeveloped area of the Lower Campus of Hoag Memorial Hospital Presbyterian and in close proximity to the subject site. The results are reported in "Preliminary Geochemical Site Evaluation of Existing Relief Wells, Gaseous Flare, Soil, Water and Air on a Portion of Hoag memorial Hospital Presbyterian Property Newport Beach, California" dated 22 April 1992. That investigation found noncorrosive soils in the upper one foot. The current study reports on soil corrosivity to depths as great as twenty (20') feet. One (1) soil boring has been advanced to a depth of twenty (20') feet below existing grade (FIG. 2). The borehole location was chosen to cover the site under those limitations imposed by the topography and existing underground utilities. Chain -of - Custody (Appendix I) was maintained throughout the investigation. Soil samples were analyzed for corrosivity (pH) and were found within the range of 8.48 — 8.70 or nearly neutral (TAB. 2). The soils sampled are therefore not classified as a hazardous substance. No hazardous materials or excess residual hazardous substances have been identified under the scope of the subject investigation. 13 • • MITIGATION No soils were encountered that require mitigation for corrosivity with respect to site grading. The study required by Mitigation Measure 7 relating to construction material compatibility with subject soils is needed and not made a part of the subject investigation. This report did not include a construction compatibility report. The scope of the subject report has been limited to testing for corrosivity as it relates to California Code of Regulations' Title 22 definition of hazardous substances for disposal purposes. • • FIGURE 9 GEOSCIENCE ANALYTICAL, INC. 608 Halley Court Simi Valley, CA 93065 TEL.

Part of that Master Plan addresses future development of the "Lower Campus": a parcel of land immediately to the north of West Coast Highway, east of Superior Avenue and below the Newport Bluffs which is the site of Villa Balboa and Sea Faire Condominiums. Concerns have been raised about possible adverse affects soil gas conditions on the.Lower Campus may have during construction of new facilities and further into the future. In order to address those concerns GeoScience Analytical, Inc. was retained by LSA Associates, Inc. to undertake a preliminary soil, surface water and atmospheric gases sampling and analytical program. Neither LSA Associates, Inc. as Client, nor Hoag Hospital, as property owner, placed any constraints on the Contractor, nor did they suggest any interpretation of the data which were generated prior to completion of this report. On account of the preliminary nature of this study and the limited number of locations sampled hereunder, individual results may vary due to wind velocity, wind direction, barometric pressure, air temperature, and other variables. Three gas extraction wells currently exist on the Lower Campus • • site which are removing approximately 5,000 MCF of subterranean gas per month from well depths as great as 100 feet below grade (Ninyo & Moore, "Assessment of Hydrogen Sulfide and Methane Gas Hoag Hospital Master Plan", January 14, 1992). Currently this gas is being flared. Before combustion, the gas contains approximately 4,000 ppm (v/v) of hydrogen sulfide and is 46.0% by volume methane along with carbon dioxide (14.0%), nitrogen and oxygen. The nitrogen and oxygen are thought to be derived from ambient air. The oxygen concentration has been significantly depleted as a result of bacterial methane oxidation. The gas was extremely "dry" in that it contained only trace levels of heavier homologues of methane indicative of an early diagenetic production and/or in situ biodegradation. After flaring, preliminary results indicate that the methane is reduced to background levels and hydrogen sulfide is below the limits of detection in the air (0.1 ppm v/v). The combustion product of hydrogen sulfide, sulfur dioxide, is also beneath the limits of detection (0.1 ppm v/v) in all samples analyzed. Air samples collected from both the building interiors and roof vents of subterranean vent systems beneath the Child Care and Cancer Centers contained only background concentrations of methane with hydrogen sulfide below the limits of detection. Soil gas samples collected from the area of the wetlands and surrounding near surface soils contained methane concentrations from 8.1 ppm to 3,360 ppm or 6.3% of the lower explosive limit. • • Prior to the installation of gas remediation systems along West Coast Highway and within the Newport Beach Townhomes, this same area of the wetlands and surrounding soils contained concentrations of methane as high as 536,000 ppm (GeoScience Analytical, Inc., "Geochemical Investigation of near Surface Hydrocarbon Gas Accumulatlions in Soil on a Portion of Newport Beach Townhomes and 43rd and 44th Streets", March 22, 1990). With installation of two passive gas extraction systems, however, the surficial combustible gas concentrations have been reduced by more than 99.0% from 536,000 ppm to a high of 4,762 ppm. Carbon dioxide (CO2) concentrations within the Child Care Center and Cancer Center interior air spaces and outside in the open atmosphere were determined. Within the Child Care Center and Cancer Center the carbon dioxide concentration ranged from 1,800 to 3,000 ppm v/v and outside ambient air at 4' above ground level was 1,200 ppm. Samples recovered from the roof elevations downwind of the flare contained approximately 6,000 ppm v/v of carbon dioxide. Interior carbon dioxide concentrations were below levels of concern according to applicable Federal governmental standards (Occupational Safety & Health Administration, "Limits for Air Contaminants", July 1989, Table Z-1-A) . Measurements were made for the presence of benzene, toluene, ethylbenzene and xylenes in samples recovered from within the Child Care Center and Cancer Center as well as ambient air • • and subslab vents. In all cases concentrations were less than the limit of detection of 0.5 ppm v/v. Flare feedstock was also analyzed for these aromatic hydrocarbons. Feedstock gas contained less than the detection limits of benzene, toluene and ethylbenzene. Xylenes were present at less than 2.0 ppm v/v in the feedstock gas. The absence of these compounds is in agreement with an immature shallow source for the gas which is produced by early diagenetic reactions at low temperature. Samples collected from the wetlands contained no aromatic hydrocarbons above the limits of detection. Soil and water.corrosivities were determined on samples taken from the wetlands. All pH measurements were within the neutral range being neither acidic nor basic. A comprehensive Health and Safety Plan, attached herewith as Appendix B, assured all aspects of site safety during all sampling activities. Anticipated elevated levels of hydrogen sulfide and methane were of primary importance. • • 3.0 FIELD SAMPLING PROCEDURES Applicable EPA protocol was adhered to during all phases of the sampling activities (U.S. Environmental Protection Agency, "Test Methods for Evaluating Solid Wastes", Third Addition, 1986, SW-846; California Dept. of Health Services, "California Site Mitigation Decision Tree Manual", 1986). Chain -of -Custody records were maintained and are included herewith as Appendix C. A comprehensive Health and Safety Plan, attached herewith as Appendix B, assured all aspects of site safety during all sampling activities. Anticipated elevated levels of hydrogen sulfide and methane were of primary importance. Gaseous samples were of two types: those collected in 1 liter Tedlar bags and those collected in 250 cc glass containers sealed with inert teflon stoppers. Tedlar bags (SKC Type 232-01 equipped with a polypropylene valve) were filled with an oiless Dayton Speedaire pump model 2Z866. Connections between the pump and the Tedlar bag were made with 1/8" O.D. teflon tubing type TD2-03420. For sampling in remote areas such as roof vents, teflon tubing was used for the intake. For air sampling in accessible spaces such as rooms, ground level atmosphere or open space on roofs the pump intake was directly open to the atmosphere. All Tedlar bag samples, once collected, were stored in the dark. Glass sampling vessels were filled with distilled water and • • stoppered with a teflon septum leaving no headspace gas. Gas sampling was accomplished with a gas tight syringe and samples were stored in the glass vessels by water displacement. No atmospheric contamination or outgassing of the teflon occurs with this method. In some cases, ambient atmosphere was sampled by opening the vessel and draining the water. The container was then stoppered with a sample of ambient air within. Soil gas samples were collected by driving a four (4) foot probe into the soil with a slide hammer. A 1/8" teflon tube, described above, attached to a thin stainless steel rod was then lowered 4' into the probe hole. An air tight 60cc syringe was affixed to the uphole end of the tubing and one sample withdrawn to flush the tubing. Samples were withdrawn and injected into glass containers described previously. Soil samples were collected for pH measurements by removing the top 6" of soil with a spade. The soil was further disaggregated with a spatula and approximately 400 grams of soil removed with a teflon spatula and placed in a precleaned jar. The jar was sealed with a teflon lined lid and stored at ten (10) degrees Celsius in a cooler. Water samples were collected in 200cc precleaned containers by simple submergence, and were also stored at ten (10) degrees Celsius. Extraction well gas is pumped at a pressure higher than atmospheric. Therefore gas well samples required no use of secondary pumping. For tedlar bag samples, a 1/8" teflon tube was utilized to connect the well valve on the high pressure side • • of the pump to the polypropylene valve on the tedlar bag. The well pump valve was "cracked" open to flush the teflon tubing of atmospheric contamination and then the inlet of the polypropylene valve on the tedlar bag was affixed to the teflon tubing and opened, allowing the bag to fill. The valve was then closed and the tedlar bag stored in the dark. The glass containers were inverted over the teflon tubing and the incoming gas simply displaced the water. The tubing was then removed and the containers stoppered. A composite sample of all the wells was obtained in this fashion. Individual wells were sampled by isolating two (2) wells and letting the in line compressor operate for five (5) minutes to flush all composite gas from the lines. Samples were then taken as described above. Temperature measurements of the flare and thermal plume were also taken. Since the flame is approximately 20' above ground surface, the thermocouple was attached to, but insulated from, a 20' long metal pole. The thermocouple was moved to various locations within the flame and plume. At each position of a desired temperature measurement, the thermocouple was held in place until the voltage measurement stabilized. • • 4.0 ANALYTICAL METHODS Samples were analyzed by Certified Testing Laboratories, an independent testing laboratory certified by numerous California governmental agencies in addition to the Environmental Protection Agency. Chain -of -Custody forms were maintained during all aspects of the program and are made a part of the record as Appendix C, attached. Analyses were performed according to applicable EPA protocol (U.S. Environmental Protection Agency, "Test Methods for Evaluating Solid Wastes", Third Addition, 1986, SW-846) or ASTM Methods where no EPA protocol has been established. Hydrogen Sulfide/Sulfur Dioxide Tedlar bag samples were analyzed for their H2S and/or SO2 content with a gas chromatograph equipped with a Hall detector according to EPA Method 15(mod.). All samples were analyzed within 72 hours of collection. Results are reported as parts -per -million (ppm) volume/volume. Applicable QA/QC protocol was followed including standardization, blanks and replicate analyses. Benzene/Toluene.Ethylbenzene/Xvlenes (BTXE) Tedlar bag samples were analyzed for their applicable aromatic hydrocarbon content by gas chromatography using a photo - ionization detector according to EPA Method 8020. Results are reported as parts -per -million (ppm) volume/volume. Applicable • • QA/QC protocol was followed including standardization, blanks and replicate analyses. Corrosivity (PH) The corrosivity of the soil and water samples was measured according to EPA Method 9040 using a calibrated electrode. Results are reported as standard pH units. Applicable QA/QC protocol was followed including standardization, blanks and replicate analyses. Carbon Dioxide, Oxygen and Nitrogen Samples were analyzed according to ASTM Method D1946. Gas container samples were analyzed for their CO2, 02 and N2 content using a Carle Model 8700 gas chromatograph equipped with a thermal conductivity detector. The carrier gas is helium at a flow rate of 30 cc/min. Two stainless steel 1/8" 0.D. packed columns in tandem are used for the separation: an 8.0' 50/80 mesh mixture of 80% PPN/20% PPQ porapack followed by a 6.0' molecular sieve 5A 60/80 mesh. Quantitation is with an HP Model 3390A electronic integrator. Results are reported as parts -per -million (ppm) volume/volume. Applicable QA/QC protocol was followed including standardization, blanks and replicate analyses. Cl-C7 Hydrocarbons Glass container samples were analyzed for their methane, ethane, • • ethylene, propane, propylene, isobutane, n-butane, isopentane, n-pentane, isohexane, n-hexane, isoheptane and n-heptane content using a model 2400 dual column Varian gas chromatograph equipped with flame ionization detectors. The separation is achieved with an 8.0' stainless steel 1/8" O.D. column packed with 100/120 mesh alumina. Temperature programming occurs from 70 - 240 degrees Celsius at 15 degrees per minute. Quantitation is with an HP 3390A electronic integrator. Results are reported as parts -per -million (ppm) volume/volume. Applicable QA/QC protocol was followed including standardization, blanks and replicate analyses. Flame Temperature The flame and thermal gradient plume was measured with an Omega Engineering Inc. Type K nickel -chromium alloy/ nickel -aluminum alloy thermocouple (Cromel-Alumel) affixed to a 20' steel tube. The voltage output was measured with a Model 9176 Varian strip chart recorder set at 50 mV full scale deflection. Power for the recorder was supplied by a 3500 watt generator. Results are reported as degrees Celsius. Calibration was performed before, during, and following field measurments. • 5.0 RESULTS AND DISCUSSION Hoag Memorial Hospital Presbyterian (Hoag Hospital) has submitted.a Master Plan development application which is the subject of a Draft Environmental Impact Report dated October 1991 that is currently undergoing review by the City of Newport Beach. Part of that Master Plan addresses future development of the "Lower Campus", a parcel of land immediately to the north of West Coast Highway, east of Superior Avenue and below the Newport Bluffs which is the site of Villa Balboa and Sea Faire Condominiums. Seventy-three (73) samples were collected from the soil and air of the subject property as part of the current study. Sample types and locations are identified in Table 1. The gas being supplied to the existing flare contains 46.0% methane (TAB. 2) and approximately 4,000 ppm of hydrogen sulfide (TAB. 5). These values, measured on four (4) distinct samples of flare feedstock, are in good agreement with previous studies of the well gas. The flare is currently combusting approximately 50 lbs. of sulfur, as hydrogen sulfide, per day from the production of the shallow gas extraction wells. This effluent is not creating any detectable levels of hydrogen sulfide or sulfur dioxide in the ambient air. Anticipated scrubbing of the feedstock to remove hydrogen sulfide will reduce the possibility of future atmospheric pollution due to sulfur from the extraction wells. • • • Air samples taken at the Child Care Center and the Cancer Center, as well as samples from throughout the site did not detect hydrogen sulfide or sulfur dioxide above the limits of detection (TAB. 5). Only trace levels of methane are present on the subject site, except for the area of the wetlands and in decaying surface vegetation. Four (4) samples taken from the roof and interior of the Child Care Center and Cancer Center were analyzed for an expected combustion product of methane, carbon dioxide, and a hydrogen sulfide combustion product, sulfur dioxide, and aromatic hydrocarbons. The background concentration of carbon dioxide in the atmosphere is approximately 350 ppm v/v in pristine environments ("Handbook of Chemistry & Physics", 53rd Addition, CRC Press). Automobiles, power plants and sewage decay are known large producers of carbon dioxide. Five (5) air samples taken at an elevation of approximately 15 - 35 feet above grade contained carbon dioxide concentrations of approximately 5,500 ppm v/v (TAB. 4). The existing flare effluent was calculated to contain roughly 600,000 ppm v/v of carbon dioxide which is apparently undergoing dilution by a factor of 100 in the ambient air downwind of the flare. Nine (9) samples were analyzed for sulfur dioxide and did not contain SO2 above the level of detection of 0.1 ppm v/v which suggests that the SO2 reacted by conversion to sulfate (TAB. 5). Five (5) air samples which were collected from subsiab vents did not contain levels of methane or other hydrocarbons above • • background. Carbon dioxide concentrations were similar to that found in the surrounding air. No sulfur dioxide or hydrogen sulfide were detected in the vent gases above the limit of detection of 0.1 ppm v/v (TAB. 5). The maximum temperature of the flare was measured at approximately 600 degrees Celsius (FIG. 2) which means that the gas density is about one half its normal atmospheric value. Therefore,• the flare plume rises very quickly thereby mitigating any negative adverse impact on neighboring on -site buildings. The relatively low combustion temperature of the flare is caused by the very low BTU content of the gas (less than 500 BTU) which means that the formation of oxides of nitrogen is highly unlikely. The thermal gradient has been measured and is schematically represented in Figure 2. Sixteen (16) gas samples were collected at ground level throughout the Upper and Lower Campus areas and contained carbon dioxide concentrations ranging as high as 1,800 ppm v/v in a few cases during periods of reduced sea breezes (TAB. 4). These levels are the probable result of automobile exhaust and other combustion processes and do not pose a health risk. Existing governmental standards identify threshholds of 5,000 - 20,000 ppm v/v as levels of concern over extended periods of time within enclosed spaces. Five (5) representative gas samples were collected at shallow depths throughout the wetlands and surrounding areas. No samples contained hydrogen sulfide and/or sulfur dioxide at - 19 - • • levels above the detection limit of 0.1 ppm v/v. Methane in the air samples was less than 10.0 ppm v/v and methane in soil samples was less than 100 ppm v/v in most cases. At the far west end of the wetlands near the toe of the bluff a concentration of 3,360 ppm v/v methane was observed in the shallow soil gas and in the median of West Coast Highway across from the east gate of Newport Beach Townhomes a concentration of 4,762 ppm v/v of methane was observed. Two years ago, shallow methane soil gas concentrations in this area were found to be 536,000 ppm by volume. At that time two methane mitigation systems were installed that have reduced the soil gas concentrations of methane by more than 99.0%. Both systems were financed as the result of funds appropriated through the actions of. State Senator Marian Bergeson. One system was installed on the north side of West Coast Highway by Merrill Wright and the other system by GeoScience Analytical, Inc. on property owned by Newport Beach Townhomes. One gas sample was taken in a pile of composting grass clippings• and contained 2,317.0 ppm v/v of methane (TAB. 2). Carbon dioxide was present at a concentration of almost 81,000 ppm v/v (TAB. 4). .The grass pile was noticably warm and emitted an organic odor typically associated with composting vegetation. Decaying vegetation is a potent source of methane and carbon dioxide found in and around the wetlands. It is possible that the wetlands contribute substantially to near surface methane found in the surficial soils and atmosphere. - 20 - • • • Carbon dioxide concentration of the wetlands airspace, measured at seven (7) locations, was somewhat elevated over background levels of 350 ppm v/v. The carbon dioxide in the -grass clippings would indicate that some comes from decaying vegetation in the wetlands. The balance may be from urban activities such as automobile exhaust, home heating, commercial heating, etc. as suggested by the elevated levels along West Coast Highway and within parking lots of the Upper Campus (TAB. 4). Of seven (7) locations sampled, no ambient air samples or shallow soil gas samples contained benzene, toluene, ethylbenzene or xylenes at levels greater than the detection limit (TAB. 7). The flare feedstock was also void of these compounds with the exception of trace levels of xylene far below levels of concern: OSHA standards for xylene in the work place are from 100.0 - 150.0 ppm v/v while the flare feedstock contains less than 2.0 ppm v/v. Hydrocarbons are all flammable and are consumed by the flare. There is no detectable release of aromatic hydrocarbons on the site nor has a source been identified. The pH of three (3) soil and four (4) water samples recovered from the wetlands was measured (TAB. 6). Soil samples were retrieved from a depth of 6" below grade and water was taken from the surface. All samples were. neutral. In no case was an acidic or alkaline soil or water identified on the subject site. • APPENDIX A DATA TABLES AND FIGURES • • • FIGURE 1 SITE PLAN SAMPLING LOCATIONS O AIR SAMPLE A SOIL SAMPLE.

The purpose of this plan is to identify procedures for avoiding unknown hazards, avoiding personnel injury from equipment present on site, monitoring possible exposures, and responding to serious exposure or accident. The safety rules given in this plan cannot cover every eventuality. It is expected, therefore, that all workers involved will exercise good judgment in all safety matters, even though not specifically mentioned. Site Information The site is located in Newport Beach, California, as shown in Figure 1. The site covers approximately 10 acres and is comprised of two (2) buildings and vacant land. Site History The site geochemistry has been studied by GeoScience Analytical, Inc. and most recently presented in a Draft Environmental Impact Report prepared by LSA Associates Inc. Chemicals of Concern Preliminary assessment of the chemicals potentially on site has found them to be light hydrocarbons, carbon dioxide, H2S, SO2 and primarily related to a flare, vent wells and a leaking shallow subsurface sand. Methane and heavier hydrocarbons are known to exist in the surficial soils of the site with methane concentrations exceeding the Lower Explosive Limits (5.0%). Non -methane hydrocarbons are in low concentration. Hydrogen sulfide concentration has been found to be approximately 4,000 ppm in near surface soils and flare feedstock gas. WORK ACTIVITIES • GeoScience Analytical, Inc. (GSA) is contracted by LSA Associates Inc. to drill boreholes and collect soil and air samples for chemical analyses as well as to sample existing wells and the associated flare. The sampling operations will begin immediately with only shallow 4' soil probes conducted at this time in lieu of deeper borings. • • • • • HAZARD ASSESSMENT Chemical Hazards At this time, the chemical hazard onsite has not been adequately identifed. However, the chemicals found in the soil and the past and present use of the site clearly indicate that caution is necessary. Inhalation Hazard Inhalation hazards are unknown in terms of nature and extent. The Site Health and Safety Officer will ensure that monitoring of the breathing zone be conducted during the drilling operations. If the measurements exceed 20% LEL (methane) in the breathing zone, all personnel will be required to wear respirators. If the measurements exceed 25% LEL in the breathing zone, work will be stopped and the site will be evacuated. If hydrogen sulfide concentration is found to exceed 100ppm in the breathing zone within the work zone, work will be stopped and the site will be evacuated until the concentration is reduced. If hydrogen sulfide odor becomes noxious to nearby residents who are within their homes, the residents will be advised to leave the area and the Newport Beach Fire Department will be notified. If hydrogen sulfide readings exceed 100ppm in the breathing zone within the work area, all personnel are to evacuate the work area and notify the Corporate Health and Safety Officer. Hydrogen sulfide concentration will be monitored in the work zone. In the event hydrogen sulfide concentration exceeds 100ppm in the breathing zone of the work area, the Fire Department will be notified and the area subjected to evacuation. All trenches will be immediately filled with suitable material and capped with bentonite hole plug. The existing ventilation systems will be kept on during all operations. An additional exhaust blower will be utilized during boring or trenching operations and will be ducted to the atmosphere. Dermal Exposure Hazard Protective neoprene gloves shall be worn during the • • • handling of the soil or soil contaminated tools in the event soil contamination is encountered. No dermal hazards are expected on -site. Protective goggles must be worn if contaminated soils are identified by visual observations. Saranex coveralls must be worn when drilling in wet conditions. If unexpected liquids are encountered, drilling must be halted while personnel change into Saranex coveralls. Further splash protection will be augmented by taping the cuff of the pant legs to the boot and likewise the sleeve to the wrist. Uncoated Tyvek will be used only during dry conditions. Heat Stress Due to the coastal conditions in which drilling activities will take place, heat stress will not be a concern. Water will be made available near the drilling rig so workers can conveniently consume fluids. Heat stress can result when protective clothing decreases natural body ventilation. If temperatures on -site exceed 85 degrees F while protective coveralls are being worn, then heat stress monitoring may be required. Noise Hearing protection should be worn by personnel within the 25' exclusion zone when the drill rig or backhoe is operating. • • • SAFETY GUIDELINES FOR DRILLING Drill rig and backhoe maintenance and safety is the responsibility of the drill rig and backhoe operators, respectively. The following information is provided as general guidelines for safe practices onsite. Off -Road Movement of Drill Rigs and Backhoes The following safety guidelines relate to off -road movement: Before moving a drill rig and backhoe, first walk the route of travel, inspecting for depressions, slumps, gulleys, ruts and similar obstacles. "None of these are expected on the subject site." Always check the brakes of a drill rig or backhoe carrier before traveling, particularly on rough, uneven or hilly ground. Discharge all passengers before moving a drill rig and backhoe on rough or hilly terrain. Engage the front axle when traveling off highway on hilly terrain. Use caution when traveling side -hill. Conservatively evaluate side -hill capability of Drill Rigs and Backhoes, because the arbitrary addition of drilling tools may raise the center of mass. When possible, travel directly uphill or downhill. Attempt to cross obstacles such as small logs and small erosion channels or ditches squarely, not at an angle. Use the assistance of someone on the ground as a guide when lateral or overhead clearance is close. After the drilling rig has been moved to a new driliz._g site, set all brakes and/or locks. When grades are steep, block the wheels. Never travel off -road with the mast (derrick) of the drill rig in the raised or partially raised position. Tie down loads on the drill rig and backhoe and support trucks during transport. • • • Overhead and Buried Utilities The use of a drill rig or backhoe near electrical power lines and other utilities requires that special precautions be taken by both supervisors and members of the exploration crew. Electricity can shock, it can burn and it can cause death. Overhead and buried utilities should be located, noted and emphasized on all boring location plans and boring assignment sheets. When overhead electrical power lines exist at or near a drilling site or project, consider all wires to be live and dangerous. Watch for sagging power lines before entering a site. Do not lift power lines to gain entrance. Call the utility and ask them to lift or raise the lines and deenergize. Before raising the drill rig mast on a site in the vicinity of power lines, walk completely around the drill rig. Determine what the minimum distance from any point on the drill rig to the nearest power line will be when the mast is raised and/or being raised. Do not raise the mast or operate the drill rig if this distance is less than 20 ft. Keep in mind that both hoist lines and overhead power lines can be moved toward each other by the wind. If there are any questions whatsoever concerning the safety of drilling on sites in the vicinity of overhead power lines, call the power company. The power company will provide expert advice at the drilling site as a public service and at no cost. Underground electricity is as dangerous as overhead electricity. Be aware and always suspect the existence of underground utilities such as electrical power, gas, petroleum, telephone, sewer and water. Always contact the owners of utility lines or the nearest undergound utility location service before drilling. The utility personnel should determine the location of underground lines, mark and flag the locations, and determine jointly with utility personnel what specific precautions must be taken to assure safety. If a sign warning of underground utilities is located on a site boundary, do not assume that underground utilities are located on or near the boundary or property line under the sign. Call the utility and check it out. The underground utilities may be a considerable distance away from the warning sign. • • Clearing the Work Area Prior to drilling or digging, adequate site cleaning and leveling should be performed to accommodate the drill rig or backhoe and supplies and provide a safe working area. Drilling should not be commenced when tree limbs, unstable ground or site obstructions cause unsafe tool handling conditions. Note: In coordination with the Drilling Crew, the Site Health and Safety Officer will review the precautions taken to insure that the drill rig or backhoe is leveled and stabilized. Housekeeping On and Around the Drill Rig or Backhoe The first requirement for safe field operations is that the Site Safety Officer understands and fulfills the responsibility for maintenance and "housekeeping" on and around the drill rig or backhoe. Suitable storage locations should be provided for all tools, materials and supplies so that they can be conveniently and safely handled without hitting or falling on a member of the drill crew or a visitor. Avoid storing or transporting tools, materials or supplies within or on the mast of the drill rig or backhoe. Pipe, drill rods, bits casing, augers and similar drilling tools should be neatly stacked on racks or sills to prevent spreading, rolling or sliding. Penetration or other driving hammers should be placed at a safe location on the ground or be secured to prevent movement when not in use. Work areas, platforms, walkways, scaffolding and other access ways should be kept free of materials, obstructions and substances such as ice, excess grease, or oil that could cause a surface to become slick or otherwise hazardous. Keep all controls, control linkages, warning and operation lights and lenses free of oil, grease and/or ice. Do not store gasoline in any portable container other than a non -sparking, red container with a flame arrester in the fill spout and having the word "gasoline" easily visible. • • • Safe Use of Hand Tools There are almost an infinite number of hand tools that can be used on or around a drill rig or backhoe. "Use the tool for its intended purpose" is the most important rule. The following are a few specific and some general suggestions which apply to safe use of several hand tools that are often used on and around Drill Rigs and Backhoes. * When a tool becomes damaged, either repair it before using it again or get rid of it. * When using a hammer, any kind of hammer for any purpose, wear safety glasses and require all others near you to wear safety glasses. * When using a chisel, any kind of chisel, for any purpose, wear safety glasses and require all others around you to wear safety glasses. * Keep all tools cleaned and orderly stored when not in use. * Replace hook and heel jaws when they become visibly worn. * When breaking tool joints on the ground or on a drilling platform, position your hands so that your fingers will not be smashed between the wrench handle and the ground or the platform, should the wrench slip or the joint suddenly let go. Safe Use of Wire Line Hoists, Wire Rope and Hoisting Hardware The use of wire line hoists, wire rope, and hoisting hardware should be as stipulated by the American Iron and Steel Institute's Wire Rope Users Manual. All wire ropes and fittings should be visually inspected during use and thoroughly inspected at least once a week for abrasion, broken wires, wear, reduction in rope diameter, reduction in wire diameter, fatigue, corrosion, damage from heat, improper weaving, jamming, crushing, bird caging, kinking, core protrusion and damage to lifting hardware and any other feature that would lead to failure. Wire ropes should be replaced when inspection indicates excessive damage according to the wire rope users manual. If a ball -bearing type hoisting swivel is used to hoist • • drill rods, swivel bearings should be inspected and lubricated daily to assure that the swivel freely rotates under load. If a rod slipping device is used to hoist drill rods, do not drill through or rotate drill rods through the slipping device, do not hoist more than 1 foot of the drill rod column above the top of the mast, do not hoist a rod column with loose tool joints and do not make up, tighten or loosen tool joints while the rod column is being supported by a slipping device. If drill rods should slip back into the borehole, do not attempt to brake the fall of the rods with your hands. Most sheaves on drill rigs are stationary with a single part line. The number of parts of line should not ever be increased without first consulting with the manufacturer of the drill rig. Wire ropes must be properly matched with each sheave. The following procedures and precautions must be understood and implemented for safe use of wire ropes and rigging hardware. Use tool handling hoists only for vertical lifting of tools. Do not use tool handling hoists to pull on objects away from the drill rig or backhoe; however, drills may be moved using the main hoist as the wire rope is spooled through proper sheaves according to the manufacturer's recommendations. When stuck tools or similar loads cannot be raised with a hoist, disconnect the hoist line and connect the stuck tools directly to the feed mechanism of the drill. Do not use hydraulic leveling jacks for added pull to the hoist line or the feed mechanism of the drill. When attempting to pull out a mired down vehicle or drill rig or backhoe carrier, only use a winch on the front or rear of the vehicle or drill rig or backhoe carrier and stay as far away as possible from the wire rope. Do not attempt to use tool hoists to pull out a mired down vehicle or drill rig or backhoe carrier. Minimize shock loading of a wire rope - apply loads smoothly and steadily. * Protect wire rope from sharp corners or edges. * Replace faulty guides and rollers. * Replace worn sheaves or worn sheave bearings. * Replace damaged safety latches on safety hooks before using. • • * Know the safe working load of the equipment and tackle being used. Never exceed this limit. * Clutches and brakes of hoists should be periodically inspected and tested. * Know and do not exceed the rated capacity of hooks, rings, links, swivels, shackles and other lifting aids. * Always wear gloves when handling wire ropes. * Do not guide wire ropes on hoist drums with your hands. * Following the installation of a new wire rope, first lift a light load to allow the wire rope to adjust. * Never carry out any hoisting operations when the weather conditions are such that hazards to personnel, the public or property are created. * Never leave a load suspended in the air when the hoist is unattended. * Keep your hands away from hoists, wire rope, hoisting hooks, sheaves and pinch points as slack is being taken up and when the load is being hoisted. * Never hoist the load over the head, body or feet of any personnel. Safe Use of Augers The following general procedures should be used when advancing a boring with continuous flight or hollow -stem augers: * Prepare to start an auger boring with the drill rig level, the clutch or hydraulic rotation control disengaged, the transmission in low gear and the engine running at low RPM. * The operator and tool handler must establish a system of responsibility for the series of various activities required for auger • Start Up drilling, such as connecting and disconnecting auger sections, and inserting and removing the auger fork. The operator must assure that the tool handler is well away from the auger column and that the auger fork is removed before starting rotation. * Only use the manufacturer's recommended method of securing the auger to the power coupling. Do not touch the coupling or the auger with your hands, a wrench or any other tools during rotation. * Whenever possible, use tool hoists to handle auger sections. * Never place hands or fingers under the bottom of an auger section when hoisting the auger over the top of the auger section in the ground or other hard surfaces such as the drill rig platform. * Never allow feet to get under the auger section that is being hoisted. * When rotating augers, stay clear of the rotating auger and other rotating components of the drill rig. Never reach behind around a rotating auger for any reason whatever. * Never use your hands or feet to move cuttings away from the auger. * Augers should be cleaned only when the drill rig is in neutral and the augers are stopped from rotating. All drill rig or backhoe personnel and visitors should be instructed to "stand clear" of the drill rig or backhoe immediately prior to and during starting of an engine. Make sure all gear boxes are in neutral, all hoist levers are disengaged, all hydraulic levers are in the correct nonactuating positions and the cathead rope is not on the cathead before starting a drill rig or backhoe engine. • • • Safety During Drilling and Backhoe Operations Safety requires the attention and cooperation of every worker and site visitor. Do not drive the drill rig or backhoe from hole to hole with the mast in the raised position. Before raising the mast look up to check for overhead obstructions. Before raising the mast, all drill rig personnel and visitors should be cleared from the areas immediately to the rear and the sides of the mast. All drill rig personnel and visitors should be informed that the mast is being raised prior to raising it. Before the mast of a drill rig is raised and drilling is commenced, the drill rig must be first leveled and stabilized with leveling jacks and/or solid cribbing. The drill rig should be releveled if it settles after initial set up. Lower the mast only when leveling jacks are down and do not raise the leveling jack pads until the mast is lowered completely. Before starting drilling operations, secure and/or lock the mast if required according to the drill manufacturer's recommendations. The operator of a drill rig or backhoe should only operate a drill rig or backhoe from the position of the controls. The operator should shut down the drill engine before leaving the vicinity of the drill. Do not consume alcoholic beverages or other depressants or chemical stimulants prior to starting work on a drill rig or backhoe or while on the job. Watch for slippery ground when mounting/dismounting from the platform. All unattended boreholes and trenches must be adequately covered or otherwise protected to prevent drill rig or backhoe personnel, site visitors or animals from stepping or falling into the hole. All open boreholes should be covered, protected, or backfilled adequately and according to local or state regulations on completion of the drilling project. "Horsing around" within the vicinity of the drill rig or backhoe and tool and supply storage areas should never be allowed, even when the drill rig or backhoe is shut down. Before lifting a relatively heavy object, approach the object by bending at the knees, keeping your back vertical and • • • unarched while obtaining a firm footing. Grasp the object firmly with both hands and stand slowly and squarely while keeping your back vertical and unarched. In other words, perform the lifting with the muscles in your legs, not with the muscles in your lower back. A flame ionization gas chromatograph will operate real time during the entire drilling operation. Prior to concrete cutting, excavation or welding operations, free soil gas combustible hydrocarbons will be vented or diluted to a concentration less than 25% LEL. The Project Manager will stop all remediation activities in the event free soil gas gas combustible hydrocarbons exceed 25% LEL. • • GENERAL HEALTH AND SAFETY REQUIREMENTS Physical Examinations and Site Training All GeoScience Analytical, Inc. (GSA) personnel are required to have undergone a complete physical examination where the examining physician has declared them physically able to work on a hazardous waste site and to participate in all activities required of them in that position. All GSA personnel are also required to have completed a basic hazardous waste training class wherein they are fit tested for a respirator. Site Safety Meeting Site safety orientation/training meetings must be convened a) before the field team begins work at the site, b) when there are modifications to the site safety plan that are applicable to the field personnel, and c) when additional staff of subcontractors begin field work. Meetings will be attended by personnel involved in carrying out the project and presided over by the Site Health and Safety Officer. A list of attendees will be provided to the Project Health and Safety Officer. At a minimum, the meeting agenda must include: a. a review of the Site Safety Plan; b. distribution of Site Safety Plan modifications; c. attendee signatures, acknowledging receipt and understanding of the plan and agreement to comply. • • • The Site Safety Officer The Site Health and Safety Officer is responsible for carrying out the health and safety requirements detailed in this plan and has the authority to halt work or dismiss people from the site if they do not adhere to the plan. The Site Health and Safety Officer should maintain a list of addresses and telephone numbers of emergency assistance units (ambulance services, police, hospitals, etc.) and inform other members of the drill crew of the existence and location of this list. He will maintain a copy of the Health and Safety Plan on site. Safety Completion Reports The Site Health and Safety Officer will prepare a Safety Completion Report to be submitted at the end of the project to the Project Health and Safety Officer. These reports will include a documented list of meter readings, protection decisions, actions, etc. as required by HS-509. Visitor Clearances Maximum efforts will be made to restrict unauthorized personnel from entering within 25 feet of the work area unless they comply with the safety requirements of this plan. • • SITE SPECIFIC HEALTH AND SAFETY REQUIREMENTS Drilling and Digging Operations A section of this health and safety plan has outlined general safety guidelines for drilling which should be followed. Further requirements are as follows. Where necessary, level pads must be constructed to ensure that the rig is in no danger of tipping over during operation. A work area will also be defined around the drilling rig with barricades (25 foot radius) and no one will be allowed inside without appropriate protective gear. During drilling operations personnel within the work zone (25 feet) must wear steel -toed rubber boots, Tyvek coveralls, butyl -neoprene gloves, hard hat, and safety goggles or glasses. The Site Health and Safety Officer must be present at the rig during drilling and will have monitored the work areas with a combustible gas meter. If sustained readings exceed 20% LEL methane in the breathing zone, respirators (half face) must be worn if drilling is to continue. If readings exceed 25% LEL methane the area must be evacuated until vapor levels dissipate. If liquids are encountered, drilling must be halted while personnel change into coated Saranex coveralls. Uncoated Tyvek will be used only during dry conditions. A flame ionization gas chromatograph will operate real time during the entire drilling operation. Prior to concrete cutting, excavation or welding operations, free soil gas combustible hydrocarbons will be vented or diluted to a concentration less than 25% LEL. The Project Manager will stop all remediation activities in the event free soil gas gas combustible hydrocarbons exceed 25% LEL. Air Duality and Personnel Exposure Monitoring The Site Health and Safety Officer (or his designee) will be required to monitor the initial work areas with a combustible gas meter. If the readings exceed 20% LEL methane in the breathing zone, half -face respirators must be worn to continue the exploration. If readings exceed 25% LEL in the breathing zone, all personnel are to evacuate the work area and notify the Corporate Health and Safety Officer. If hydrogen sulfide readings exceed 100ppm in the breathing zone within the work area, all personnel are to • • evacuate the work area and notify the Corporate Health and Safety Officer. Hydrogen sulfide concentration will be monitored within the work zone. In the event hydrogen sulfide concentration exceeds 100ppm in the breathing zone, the Fire Department will be notified and the area subjected to evacuation. All trenches will be immediately filled with suitable material and capped with bentonite hole plug. Heat Stress Due to the Southern California climate, heat stress may be a concern. Commercially available water and GatorAde will be made available. Heat stress can result when protective clothing decreases natural body ventilation. If temperatures on -site exceed 85 degrees F while protective coveralls are being worn, then heat stress monitoring will be required. Noise Hearing protection must be worn by the drill rig or backhoe operator and helper and all others within the work zone of the rig while the rig is in operation. Personnel and Equipment Decontamination A decontamination station and procedure will be established by the Site Health and Safety Officer during site mobilization. This will consist of a liquid soap and warm water wash for boots, gloves, respirators, and hard hat. Tyvek will be placed in a plastic bag and then disposed of. Prior to eating or drinking, the hands and face will be washed with soap and water. Traffic When a work site encroaches upon public streets, the possibility of an individual being injured or struck by vehicular traffic must be considered. At all times, personnel must be aware when moving from a protected area. Barricades and devices must be used to warn traffic. • • • EMERGENCY RESPONSE PROCEDURES In the event of fire, explosion, injury, or accident, contact the appropriate site emergency response group from the list below: Fire Department: Hospital: Ambulance: Paramedics: Poison Control: GeoScience Analytical, Inc. 911 (714) 645-8600 911 911 (714) 634-5988 (805) 526-6532 Directions to the Nearest Hospital The nearest hospital to the site is: Hoag Memorial Hospital 301 Newport Blvd. Newport Beach, CA Directions to the hospital from the site are as follows: Enter hospital directly from work area by going north on Newport Blvd. from West Coast Highway. • Position APPROVAL/DISTRIBUTION OF HEALTH AND SAFETY PLAN Name Signature Project Manager: Fleet E.

This evaluation shall be conducted by an expert in the field of corrosivity. The site evaluation shall be designed to address soils to at least the depth to which excavation is planned At a minimum, at least one sample from each soil type should be evaluated. Appropriate personnel protection should be worn by field personnel during the field evaluation. In the event soils are found to be corrosive, the source and extent of the corrosive soils should be determined and fully understood This is important for the development of mitigation measures to control the potential impact of corrosive soils over time." "Based on the corrosion assessment and source determination, a soils and construction material compatibility evaluation should also be undertaken, concluding with the appropriate mitigation measures and design criteria. Corrosion resistant construction materials are commonly available and should be used where design specifications require protection. For example, there are many elastomers and plastics, like PVC, which are resistant to corrosion by up to 70 percent acid at 140 degrees Fahrenheit." Should the soil be identified as hazardous due to the severeness of their corrosivity (i.e., a pH less than 2.5), on -site remediation by neutralization should be undertaken prior to construction. Appropriate regulatory agency approvals and permits should also be obtained" • • • Hoag Hospital Project: Heart and Vascular Institute Projects Mitigation Measure: 7 Based on the corrosion assessment and source determination, a soils and construction material compatibility evaluation shall be undertaken, concluding with the appropriate mitigation measures and design criteria. Corrosion resistant construction materials are commonly available and shall be used where the evaluation/assessment concludes that corrosive soils conditions could adversely impact normal construction materials or the materials used for the mitigation of subsurface gas conditions. For example, there are many elastomers and plastics, like PVC, which are resistant to corrosion by up to 70 percent sulfuric acid at 140 degrees Fahrenheit.

Also included is soil corrosivity test data from this site that we tested in 1995 for Hoag Hospital. The purpose of these tests was to determine if the soils may have deleterious effects on underground utilities, hydraulic elevator cylinders, and concrete foundations. • The scope of this study is limited to a determination of soil corrosivity and general corrosion control recomrhendations for materials likely to be used for construction.. If the architects and/or engineers desire more spedfie information, designs, specifications, or review of design, we will be happy to work with them as a separate phase of this project. TEST PROCEDURES The electrical resistivity of each sample was measured in a soil box per ASTM 057 in its as - received condition and appin after saturation with distilled water. Resistivities arc at about their lowest value when the soil is saturated, The•pH. of the saturated samples was measured. A 5:1 water:soil extraet from, each sample was chemically analyzed for the major anions and cations. Test results are shown on Table 1.

The electrical resistivity of a soil is a measure of its resistance to the :low of electrical current. Corrosion of buried metal is an electrochemical process in which the amount of metal loss due to corrosion is directly -proportional to the flow of electrical current (DC) from the metal into the soil. Corrosion currents, following Ohm's Law, are inversely proportional to soil resistivity. Lower electrical resistivities result from higher moisture and chemical contents and indicate corrosive soil. A correlation between electrical resistivity and corrosivity toward ferrous metals.is: Soil Resistivity in ohm -centimeters Corrosivity Category .over 10,000 mildly corrosive 2,000 to 10,000 moderately corrosive 1,000 to 2,000 corrosive below 1,000 severely corrosive Other soil characteristics that may influence corrosivity towards metals are pH, chemical content, soil types, aeration, anaerobic conditions, and site drainage, Electrical resistivities were in moderately to severely corrosive categories with as -received moisture and at saturation. Soil pH values varied from 6.5 to 7.5. This range is slightly acidic to mildly alkaline and does not particularly enhance corrosivity. The chemical content of the sarnples was low. Tests were not made for sulfide or negative bxidation-reduction (redox) potentials because they would not exist in these aerated samples. This soil is classified as severely corrosive to ferrous metals. CORROSION CONTROL The life of buried materials depends on thickness, strength, loads, construction details, soil moistures etc., in addition to soil corrosivity, and is, therefore, difficult to predict. Of more practical value are corrosion control methods.that will increase the life of materials that would be subject to significant corrosion, • • LAW/CRANDALL MJS&A #97185 June 25, 1997 Page 3 • Steel Pipe Abrasive blast underground steel utilities and apply a high quality dielectric coating such as extruded polyethylene, a tape coating system, hot applied coal tar enamel, or fusion bonded epoxy. Bond underground steel pipe with rubber gasketed, mechanical, grooved end, or other nonconductive type joints for electrical continuity. Electrical continuity is necessary for corrosion monitoring and cathodic protection. Electrically insulate each buried steel pipeline from dissimilar metals, cement -mortar coated and • concrete encased steel, and•above ground steel pipe to prevent dissimilar metal corrosion cells and to facilitate the application of cathodic protection. Apply cathodic protection to steel piping asper NACE International RP-0169-92. As an alternative to dielectric coating and cathodic protection, apply a 3/4 inch cement mortar coaling or encase in cement -slurry or concrete 3 inches thick, using any type of cement. Hydraulic Elovator Coat hydraulic elevator cylinders as described .above. Electrically insulate each cylinder from building metals by installing dielectric material between the piston platen and car, insulating the bolts, and' installing an insulated joint in the oil line. Apply cathodic protection to hydraulic cylinders as per NACE International RP-0169-92. As an alterative to electrical insulation and cathodic protection, place each cylinder in a plastic casing with a plastic watertight seal at the bottom. The elevator oil line should be placed above ground if possible but, if underground, should be protected es described above for steel utilities. Iron Pipe Encase ductile .iron water piping in 8 mil thick low -density polyethylene or 4 mil thick high - density, cross -laminated polyethylene plastic tubes or wraps per AWWA Standard CI05 or coat with a high quality dielectric coating such as polyurethane or coal tar epoxy. As an alternative, encase iron piping with cement slurry or concrete at least 3 inches thick surrounding the pipe, using any type of cement. Bond all nonconductive type joints for electrical continuity. Electrically insulate underground iron pipe from dissimilar metals' and above ground iron pipe with insulated joints. Encase cast iron drain lines in 8 mil thick low -density polyethylene or 4 mil thick high -density, cross -laminated polyethylene plastic tubes or wraps per AWWA Standard C105. As an alternative, encase iron piping with cement slurry or concrete at least 3 inches thick' surrounding the pipe, using any type of cement. Electrically insulate underground iron pipe 'from dissimilar metals and above ground iron pipe with insulated joints. . • • LAW/CRANDALL MJS&A 497185 June 25, 1997 Page 4 - Copper Tube Bare copper tubing for cold water should be bedded and backf lied in the silty sand at Ieast 2 inches thick surrounding the copper. Hot water tubing may be subject to a higher corrosion rate. The best corrosion control measure would be to place the hot copper tubing above ground. If buried, encase in plastic pipe to prevent soil contact or apply cathodic protection. Plastic and Vitrified Clay Pipe No special precautions are required for plastic and vitrified clay piping placed underground from a corrosion viewpoint. Protect any iron valves and fittings with a double polyethylene wrap per AWWA C105 or as described below for bare steel appurtenances. Where concrete thrust blocks are to be placed against iron, use a single polyethylene wrap to prevent concrete/iron contact and to eliminate the slipperiness of a double wrap. All Pipe On all pipe, coat bare steel appurtenances such as.bolts, joint harnesses, or flexible couplings with a coal tar or elastomer based mastic, coal tar epoxy, moldable sealant, wax tape, or equivalent after assembly. Where metallic pipelines penetrate concrete structures such. as building floors or walls, use plastic sleeves, rubber seals, or other dielectric material to prevent pipe contact with the concrete and reinforcing steel. Concrete Any type of cement and standard concrete cover over reinforcing steel may be used for concrete structures and pipe in contact with these soils. Please call if you have any questions.
