1.0 EXECUTIVE SUMMARY KAS and Daly Environmental Contracting (Daly) completed the approved Brownfields remediation work at the former Crawford’s Autoland, located at 89 Crawford Autoland Lane in South Royalton, Vermont from October 18 - December 16, 2013. A total of 344 tons of petroleum-contaminated soil were removed from the property. Five areas of shallow soil contamination were capped with a geosynthetic fabric, clean sand, topsoil, seed and mulch. The floor drain drywell system was properly decommissioned and the wastes from this system were drummed and disposed of. A replacement groundwater monitoring well was installed to replace two monitoring wells which were destroyed during soil excavation. One round of groundwater and drinking water well monitoring was conducted and the results were satisfactory. It is believed that this work has achieved the desired outcome of preparing the property for redevelopment. KAS recommends that the property be given a Brownfields certificate of completion. The on-site groundwater monitoring wells will need to be properly abandoned to comply with state requirements.




2.0 INTRODUCTION KAS, Inc. (KAS) and Daly Environmental Contracting (Daly) completed the approved Brownfields remediation work at the former Crawford’s Autoland, located at 89 Crawford Autoland Lane in South Royalton, Vermont from October 18 - December 16, 2013 (“property”; see Site Location Map in Appendix A). This work was conducted by KAS and Daly for the Town of Royalton, Vermont (Town) property owners at the time of the remedial work, in accordance with the following documents:

Professional services agreements between a) KAS and the Town and b) Daly and the Town including Amendment #1 to each dated October 14, 2013;

A corrective action plan (CAP) prepared by ECS dated April 4, 2013, approved by the Vermont Department of Environmental Conservation (DEC) on September 9, 2013; and,

A Site Specific Quality Assurance Project Plan (QAPP) Addendum (RFA#12098) prepared by KAS dated October 23, 2013, revised November 7, 2013, approved by the US Environmental Protection Agency (USEPA) Region 1 on November 7, 2013 and by DEC on November 8, 2013.

The CAP specified the following approved work scope tasks which were included in the Professional Services Agreements referenced above:

Preparation of a Quality Assurance Project Plan Addendum (CAP Task 5.0); Closure of Drywell and Associated Components (AOC#1) (CAP Task 3.2); Excavation and Off-Site Disposal (AOC#1) (CAP Task 3.3); Capping of Shallow Contaminated Soils (CAP Task 3.4); Replacement groundwater monitoring well installation and sampling and testing

of the existing groundwater monitoring well network and the on-site drinking water supply well (CAP Task 4.0);

Preparation of a remediation completion report (CAP Task 7.0); and, Development of a Notice to Land Records regarding residual on-site

contamination (CAP Task 3.5).




3.0 QAPP ADDENDUM PREPARATION KAS prepared a site specific QAPP Addendum for the sample collection and laboratory analysis needed for soil disposal characterization, soil excavation confirmation sampling and groundwater and drinking water supply well testing (Appendix B). The QAPP Addendum and KAS’ approved Generic QAPP (RFA12098) for Brownfields work in the State of Vermont were used for the required sampling.

4.0 CLOSURE OF DRYWELL AND ASSOCIATED COMPONENTS On October 22, 2013, Daly cleaned and closed the internal building floor drain system including the trench drain and the sludge pit. The drain system was closed by manually scraping the solid residuals from the trough drains and drumming them for disposal. The cleaned trough drains were power washed and the wash water was collected and drummed for disposal. Following cleaning, the trough drain and sludge pit were filled with cement level to the surrounding concrete floor. One 55-gallon drum of residuals and cleaning waste was generated for disposal as hazardous waste. On October 30, 2013, Dig-safe ticket #2013-4401289 became effective on the property and for the duration of sub-surface work. On November 11, 2013, Daly and KAS excavated, removed and documented the buried concrete drywell formerly located off the building’s northwest corner. The top of the concrete drywell was encountered at 5’ below ground surface (bgs). Upon cleaning off the top it was determined the drywell had outside dimensions of 4.5’ wide x 8’ long concrete box with 6” thick walls and an 1.5’ round access hole in the top. The top was removed and the drywell was determined to be approximately 75% full of dark grey to black sandy sludge with a strong weathered petroleum odor. No liquids were encountered. The contents were contained in seven, 55-gallon steel drums. Once the contents were removed it was determined that the drywell was a 3’ deep structure with numerous 3” square holes in the sides and no bottom containment. The bottom of the drywell discharged contaminants at approximately 7’ bgs. During excavation, contaminated soils were encountered at 6’ bgs in the immediate vicinity of the concrete drywell. Away from the concrete drywell, contaminated soils were encountered at 9’ bgs. It is surmised that contamination emanating from the drywell either surcharged or diffused from the bottom at 7’ bgs upward to the depth that contamination was first encountered at 6’ bgs.




Once the drywell was emptied and documented it was removed from the ground, pressure washed and broken up for disposal. The drywell concrete was delivered to the Pike Industries Inc. Reclamation Facility located on Depot Road in Hartland, Vermont. Grossly-contaminated soils were encountered immediately beneath the drywell. These were excavated and placed in 5, 55-gallon steel drums. It is believed that the grossly contaminated soils were removed in their entirety for disposal as hazardous waste. These soils are not included in the tonnage of soils removed presented in Section 5.0. A total of 13, 55-gallon drums of hazardous waste were generated during the closure of the drywell and its associated components. The majority of this waste was floor drain and drywell solids and soil. The liquids were generated during cleaning operations. Waste characterization sampling performed by ECS and described in ECS’ Phase II ESA report dated April 2012 were provided to Environmental Products and Services of Vermont, Inc. and were deemed to be acceptable. Therefore, no additional characterization testing was necessary for closure of the drywell and related components. The drummed waste was picked up by Environmental Products and Services of Vermont, Inc. on December 16, 2013. Delivery to the designated disposal facility took place on December 20, 2013. The AOC #1 and Soil Excavation Plan showing the measured location of the buried drywell is included in Appendix A. Photos of the floor drain and drywell closure are included in Appendix D. A copy of the waste manifest is included in Appendix E.

5.0 EXCAVATION AND OFF SITE DISPOSAL

From November 11 to 13, Daly excavated 344.17 tons of contaminated soils from the ground in AOC 1 for temporary stockpiling on-site pending approval for disposal. The soil stockpile was constructed on the southwestern part of the paved parking lot where contaminated soils were temporarily piled on and beneath polyethylene plastic sheeting. Silt fencing was installed along the downhill side of the temporary soil pile. The plastic was secured with tires.




In accordance with CAP Section 3.3, soil exhibiting visual evidence of staining, petroleum or other odors, and/or field screening readings of 10 parts per million or more (as measured with a properly calibrated photoionization detector (PID) were removed. The clean overburden soils (see Section 4.0) were set aside for re-use in backfilling the excavation. The contaminated soils generally exhibited a distinct olive grey color and a pungent oily odor and PID readings up to 287 ppm. The worst contamination was encountered in the immediate vicinity of and below the drywell from a depth of 6’ bgs downward to the final limits of excavation at 15’ bgs. It is believed that the excavation successfully removed all of the contaminated soils above the target thresholds in the CAP, and in most cases, contamination was removed to well below 10 ppm. The limits of soil excavation were measured and they can be found on the AOC #1 and Soil Excavation Plan in Appendix A. Once the limits of excavation were reached, KAS collected six post-excavation soil samples from the excavation bottom and side walls. The confirmation soil sampling was performed on November 14, 2013. The conformation samples included four sidewall samples one bottom sample, and one duplicate sample. The soil samples were collected from the 13’-15’ depth interval for field screening, containerization and documentation. The PID readings for these soils ranged from 0.2-1.5 ppm. The samples were picked up by courier immediately following their collection and containerization and were transported to Eastern Analytical Inc. in Concord, New Hampshire (EAI) for analyses of the following analytes:

Volatile Organic Compounds (VOCs) by EPA Method 8260; Total Petroleum Hydrocarbons (TPH) by EPA Method 8100; Polycyclic aromatic hydrocarbons (PAH) by EPA Method 8270; and, RCRA 8 Metals.

The results of the confirmation soil sampling (Appendix C) indicated that:

No VOCs or TPH were reported in the confirmation samples. No PAH were reported except for a trace of naphthalene in the east wall

sample at a concentration 3 orders of magnitude below the DEC’s industrial soil screening value (SSV).




Concentrations of four of the eight RCRA metals (As, Ba, Cr, Pb) were reported above detection limits. The reported metals concentrations appear to be within normal ranges for Vermont soils and are not believed to be indicative of anthropogenic contamination. The reported arsenic concentration exceeded the industrial SSV in all five confirmation samples.

The remaining four RCRA metals (Cd, Hg, Se, Si) were not reported above detection limits in any of the confirmation soil samples.

Following collection of the post-excavation confirmation soil samples the excavation was backfilled with clean overburden and clean fill obtained from the on-site borrow pit. Backfill was compacted in two-foot intervals. The area was seeded and mulched to replace the surface in kind. Photographs of the excavation during and after the work was completed are in Appendix D. Following completion of the excavation, KAS collected four soil samples for disposal characterization from the soil stockpile. The samples were collected using a hand auger from the completed soil stockpile. Each sample was field screened, documented and containerized and submitted to EAI for the following analyses:

VOCs by EPA Method 8260; TPH by EPA Method 8100; Semi-volatile organic compounds (SVOCs) by EPA Method 8270; Polychlorinated biphenyls (PCBs) by EPA Method 8082 w/Soxhlet extraction; RCRA 8 Metals; Ignitibility, pH, and sulfide/cyanide reactivity.

The results of the characterization soil sampling (Appendix C) indicated:

Petroleum VOCs were reported in three of the four characterization samples at levels above detection limits. The reported concentrations were below the DEC Industrial SSVs.

No non-petroleum VOCs were reported. PAH were reported in three of the four characterization samples at levels above

detection limits. The reported concentrations were below the DEC Industrial SSVs except for benzo(a)pyrene in one sample which equaled the SSV.

Three SVOCs (bis(2- Ethylhexyl)phthalate, Di-n-octylphthalate and dibenzofuran) were reported in one or more characterization soil samples at concentrations




above detection limits. The reported concentrations were below the DEC Industrial SSVs.

Concentrations of four of the eight RCRA metals were reported above detection limits (As, Ba, Cr, Pb). The reported arsenic concentration exceeded the industrial SSV in two of four characterization samples.

The remaining four RCRA metals (Cd, Hg, Se, Si) were not reported above detection limits in any of the characterization soil samples.

TPH was reported in all four characterization samples. The reported TPH concentration exceeded the DEC Industrial SSV in two of four samples.

No PCBs were reported at concentrations above detection limits. The characterization data were submitted to Environmental Soil Management Inc. of Louden, New Hampshire (ESMI) and the soils were found to be acceptable for disposal there. The soils were loaded by Daly into trucks supplied by ESMI on December 5, 2013. Copies of the bills of lading for contaminated soil are in Appendix E. A total of 344.17 tons of contaminated soil were transported and disposed of at ESMI.

6.0 CAPPING OF SHALLOW CONTAMINATED SOILS From October 23-30, 2013, Daly installed five protective soil layers as specified in section 3.4 of the CAP. Prior to installation, each of the five AOCs were staked out in the field utilizing dimensional data derived from the CAP as they related to fixed positions including proximal building corners and groundwater monitoring wells. Prior to installing the fill soils, a layer of Propex Geotex 200ST Woven Geotextile Fabric was spread over the ground surface to the limits of AOCs as defined above. A product summary sheet is included in Appendix E. Daly used on-site sandy soil fill excavated from the on-site borrow pit to construct the five soil caps one in each of AOC 2, 3a, 3b, 3c and 4. Each soil cap is minimum 12” thickness plus topsoil. Each CAP was seeded with Vermont Conservation Mix and hay mulched in preparation for winter and commencement of vegetative growth in 2014. The locations and limits of the soil caps were measured and they can be found on the AOC #2,3,4 Plan in Appendix A. Photographs of the soil caps are in Appendix D.




7.0 MONITORING WELL REPLACEMENT On November 19, 2013, T&K Drilling working for and under the oversight of KAS installed a new, 2” groundwater monitoring well within the limits of the excavated soils in AOC #1. The new well, designated MW-1617R, was located such that it is in a position to detect residual groundwater contamination beneath the removed drywell if such contamination existed. The well was installed through approximately 15’ of sandy backfilled soils to a final depth of 33’ bgs. Soils from the limits of backfill at 15’ bgs to 33’ bgs were a fining-downward sequence of silty fine sand and sandy silt. Groundwater was encountered at an approximate depth of 25’ bgs. Evidence of contamination in the soils beneath the former drywell was not encountered except for one PID reading in the soils from 15-17’ bg where a PID reading of 7.6 ppm was encountered, below the specified threshold of 10 ppm for soil removal. The new monitoring well is finished with a steel locking standpipe. A well completion report is included in Appendix F.

8.0 DRINKING WATER AND GROUNDWATER MONITORING On November 14, 2013, KAS performed drinking water monitoring at the site in accordance with the approved QAPP addendum. The monitoring consisted of collection of a drinking water supply well sample for VOCs via EPA Method 524.2 and sample submittal to EAI, following purging of the system. On December 5, 2013, KAS performed groundwater monitoring at the site in accordance with the approved QAPP addendum. The monitoring consisted of locating, gauging and sampling existing monitoring wells and submittal of the groundwater samples for laboratory testing at EAI. The groundwater monitoring indicated that of the 19 groundwater monitoring wells intended to be sampled, six were dry, one had insufficient water to sample after purging, and one was not located and is presumed to have been destroyed. Consequently, eleven groundwater monitoring wells were sampled and tested for contaminants of concern as spelled out in the CAP.




The results of the monitoring well gauging indicated that depth to groundwater ranged from 12.95’ below top of casing (btoc) at MW-13 (parking lot area), to 45.70’ btoc at MW-19 (gravel pit area). The estimated direction of groundwater flow is toward the east. The hydraulic gradient ranged from 5% to 10 % near the dealership building. No light aqueous phase liquids were measured or observed during monitoring well gauging and sampling. Eleven groundwater samples were submitted under chain of custody procedures to EAI for analysis of VOCs via EPA Method 8260b and for RCRA 8 Metals via EPA Method 6020. No VOCs were reported in either the drinking water sample or in the eleven groundwater samples, and none of the reported metals concentration exceeded VGES in any of the groundwater samples.

9.0 DATA VALIDATION Upon receipt of all laboratory analytical data collected during the remediation work, KAS’ quality assurance officer (QAO) performed data validation as described in the approved QAPP addendum. The validation evaluated the usability of the data generated throughout the investigation. The Data Validation Report is included in Appendix G. QAPP Modifications Representative samples were collected in an appropriate manner. The scope of work and sampling procedures detailed in the QAPP were not modified based upon field conditions encountered. Verification of Sampling Procedures & Chain of Custody As indicated in the data validation report, KAS’ QAO determined that sampling appears to have been performed appropriately and is representative of the field conditions encountered. Data should be accepted based on field sampling procedures documented.

10.0 NOTICE TO LAND RECORDS A draft notice to land records communicating the presence of residual on-site contamination in the AOCs #2, 3a, 3b, 3c and 4 has been prepared and is included in Appendix H.




11.0 CONCLUSIONS AND RECOMMENDATIONS KAS and Daly completed the approved work scope contained in the April 2013 CAP document. Four of the six AOCs addressed in the CAP were remediated. The other two AOCs did not require remediation per the CAP. A total of 344 tons of petroleum-contaminated soil were removed from AOC#1. Five areas of shallow soil contamination (AOC #2, #3a, #3b, #3c, and #4) were capped including geosynthetic membrane, clean sand cap, topsoil, seed and mulch. The floor drain drywell system was properly decommissioned and the wastes from this system were drummed and properly disposed of. A replacement groundwater monitoring well was installed to replace two monitoring wells which were destroyed during soil excavation. One round of groundwater and drinking water well monitoring was conducted and the results were satisfactory. It is believed that this work has achieved the desired outcome of preparing the property for redevelopment. KAS recommends that the property be given a Brownfields certificate of completion. The on-site groundwater monitoring wells will need to be properly abandoned to comply with state requirements.

1.0 INTRODUCTION This site specific Quality Assurance Project Plan addendum (QAPP addendum) was prepared by KAS, Inc. (KAS) for performance of environmental sampling during cleanup at the Former Crawford’s Autoland Inc. property in South Royalton, Vermont (the “property”, see Site Location Map). This site specific QAPP addendum is to be used in conjunction with KAS’ approved generic QAPP #RFA 12098 for Brownfields environmental work in Vermont. Former Crawford’s Autoland has been the subject of several previous environmental assessments, including a Phase I Environmental Site Assessment (ESA), a Brownfields Phase II ESA, and an underground storage tank (UST) removal assessment and investigation. The necessary cleanup work has been laid out in a Corrective Action Plan1

Daly Environmental Contracting of South Royalton, Vermont (Daly) and

(CAP) approved by the Vermont Department of Environmental Conservation (DEC). 1.1. Project Organization

1 Crawford’s Autoland Analysis of Brownfields Cleanup Alternatives and Corrective Action Plan Final, April 4, 2013, ECS.

KAS have prepared this QAPP summary to provide Brownfields cleanup consulting services at the former Crawford Autoland. Daly and KAS will function as an integrated team, providing all necessary cleanup and consulting services outlined in the approved Corrective Action Plan (CAP) dated April 4, 2013. Daly will be the team leader and will provide all excavation, transportation and disposal, and related services. KAS will provide environmental consulting services and field support including monitor well replacement and laboratory work. 1.2. Goals and Objectives The work scope is based on the requirements of the approved CAP. It is designed to provide environmental data concerning the sampled media to assist in the property redevelopment.. 1.3. Work Scope Summary Environmental sampling and laboratory analysis are specified in three discrete aspects of the work:

• Soil waste characterization sampling prior to off-site disposal of excavated soils in the vicinity of a floor drain drywell system;

• Soil confirmation sampling around the excavated drywell



area to gauge the effectiveness of the soil removal;

• Groundwater and drinking water sampling.

This sampling is being performed to determine the overall efficacy of the cleanup as prescribed in the CAP. The specific tasks to be performed are presented in Section 1.3. Previously generated characterization data are being used to characterize the hazardous drywell sludges. The laboratory report levels and regulatory guidance levels for the suspect contaminants of concern are listed in updated Form K which is included as Appendix A. As of the date of this site-specific QAPP Addendum, the current state and/or federal standards have been incorporated into this table and the reporting limits and standards have been reviewed for accuracy. 1.4. QAPP Discussion KAS’ generic QAPP (RFA12098) for Brownfields work in Vermont contains a summary of the KAS standard protocols, laboratory standard operating procedures, and data evaluation requirements common to most brownfields projects. This site specific QAPP addendum includes a description of the unique cleanup sampling requirements for this property. The two documents are

designed to be used together to provide an overall evaluation framework for assessment and verification of data quality. Relevant standards to be utilized in this cleanup include:

• Commercial/industrial soil screening values (SSV) contained in the April 2012 State of Vermont Investigation and Remediation of Contaminated Properties document;

• Groundwater Enforcement Standards (VGES) contained in the 2005 Vermont Groundwater Protection Rule and Strategy with 2007 updates;

• Drinking Water Rules contained in the State of Vermont’s Environmental Protection Rules, Chapter 21, Water Supply Rule, December 1, 2010;

• TSCA Standards for management of PCB contaminated wastes, 40 CFR Part 761; and,

• State of Vermont Hazardous Materials Management Regulations, October 2006.

Specific protocols to be employed during execution of the work described herein are included in table F-1. A compilation of the site specific sampling requirements for the property are as documented in table F-2. A



compilation of the laboratory standard operating procedures (SOPs) to be employed during this work is included in Table F-3.

2.0 SCOPE OF WORK The work scope is based on current ASTM, EPA and DEC requirements and also discussions with project stakeholders. The following specific tasks will be carried out during the Phase II ESA. 2.1. Site Specific QAPP Addendum, HASP and Approvals Site Specific QAPP Addendum KAS will prepare a site specific QAPP addendum (this document) for review and approval by the Town of Royalton, EPA Region 1 and the Vermont DEC. This document is necessary to set forth the conditions associated with collection and testing of environmental samples. The site-specific QAPP addendum will compliment KAS’ approved Generic QAPP (RFA12098) for Brownfields work in the State of Vermont. KAS will respond to comments and will obtain site-specific QAPP addendum approval prior to on-site work involving sample collection and analysis.

Permits/ Notifications/Approvals KAS will research permitting requirements to allow the work elements to take place and will acquire necessary permits. At the present time the following permits, notifications and approvals are known:

• QAPP approval from the DEC and the EPA.

Project Coordination Daly and KAS have contracted with Town of Royalton and will conduct necessary project coordination activities to allow the project to proceed as planned. Daly and KAS will maintain active communications with the involved parties including Town of Royalton, property owner, EPA and DEC. Notice of on-site activities will be given ahead of time to allow for attendance by the involved parties if desired. KAS will conduct necessary coordination/ management activities to initiate and maintain contractual agreements required to allow the work to continue. All project documents including the QAPP and the Brownfields report will be submitted to the Town of Royalton for review before distribution. Health and Safety Plan (HASP) A site-specific HASP will be prepared and implemented to govern the safety aspects of the job in accordance with the Vermont Occupational Safety and Health Administration (VOSHA)



requirements. KAS will appoint one of its 40 hour OSHA 1910.120 trained persons as the Site Safety Officer with a backup also designated. No activities will take place on the site without a Site Safety Officer present. A copy of the HASP will be kept on site and will be available to other parties at any time requested. All HASP requirements will be passed onto subcontractors. 2.2 Designated Field Work Tasks Following is a synopsis of the work that Daly and KAS have contracted with the town to do. This work scope is directly drawn from the approved CAP document and contains additional detail and sequencing information.

Following is a summary of the tasks that this team will fulfill during the work.



SITE PREPARATION Daly will prepare the site for the remediation work. This will include mowing and brush removal, removal of various small structures (an oil tank and a shed), construction of a temporary work road to AOC #1 and staking out the AOCs in preparation for excavation and capping. Removal of the drywell and associated excavations outlined below will require removal of the two underground electric and water lines that serve the two mobile homes. It is understood that these lines do not need to be replaced. Removal of the electric lines will be performed by a licensed electrician. There is an active telephone line overhead of the drywell location which needs to be temporarily decommissioned and then re-installed following completion of the work. CLOSURE OF DRYWELL & ASSOCIATED COMPONENTS (AOC #1) The floor drain system consists of a floor trough across the garage leading to a buried concrete drywell. Once the garage is emptied of its current contents the floor drain system will be cleaned and power washed then capped with concrete. Floor drain sediments/sludge will be drummed for

transport and disposal as hazardous waste. The drywell will be decommissioned by first uncovering it then removing the top. The sediments/sludge within the drywell will be removed with a vacuum truck for off-site disposal. It is assumed this material is hazardous waste. Once the drywell is emptied it will be removed and broken up on-site for off-site disposal as construction & debris (C&D) waste. Grossly contaminated soils around and beneath the drywell, if they exist, will also be containerized either in the vacuum truck or in drums for off-site disposal as hazardous waste. If needed due to discovery of additional grossly contaminated soil beneath and around the drywell, additional characterization samples may be collected as described in this QAPP addendum Table F-2. The quantities of additional samples cannot be predicted at this time but the analytical suite would be the same as for the soil characterization samples. This work will be performed by Daly and documented by KAS. EXCAVATION & OFF-SITE DISPOSAL (AOC #1) Following removal of the drywell, 670 cubic yards (estimated 1,000 tons) of petroleum contaminated soils within the 5-15 foot depth interval will be excavated for off-site disposal. The



contaminated soils will be temporarily stored at an on-site staging area and will be placed on and covered with polyethylene sheeting. A soil berm will be built to control runoff during stockpiling. KAS will field-screen soils during the excavations for visual and olfactory indications of contamination (staining, odors, etc.) and a portable photoionization detector (PID) will be utilized to screen soils. All soils exhibiting obvious presence of contamination and/or PID readings >10 ppm will be removed. Safe set back distances will be maintained from the building and will maintain sloping at a ratio of 1.5 to 1.0. Dewatering is not anticipated as the water table is encountered below 25 feet in this area. During the excavation, KAS will collect five composite soil samples for disposal characterization. The samples will be stored on ice and transported to Eastern Analytical Inc. (EAI) for the following analyses:

• Volatile organic compounds (VOCs) by EPA Method 8260;

• Total Petroleum Hydrocarbons (TPH) by EPA Method 8100;

• Semi-volatile organic compounds (SVOCs) by EPA Method 8270;

• Polychlorinated biphenyls (PCBs) by EPA Method 8082 w/Soxhlet extraction;

• RCRA 8 Metals; • Ignitibility, pH, and

sulfide/cyanide reactivity. Following receipt of the waste characterization data by KAS and approval by the disposal facility, the soils will be loaded into dump trailers and transported to an approved disposal facility under appropriate bill of lading procedures. This work plan assumes the soils will be disposed at either Environmental Soil Management, Inc. (ESMI) of Loudon, NH via thermal desorption, or at Casella Waste Systems, Coventry, Vermont. Should the amount of soil exhibiting obvious presence of contamination and/or PID readings >10 ppm differ from the current estimate of 670 cubic yards/1,000 tons, Daly and KAS will confer with the Town, disposal facility and the DEC. Additional tonnage will require additional characterization sampling while lesser tonnage may allow for fewer characterization samples. When the excavation is complete as determined by lack of soils exhibiting obvious presence of contamination and/or PID readings >10 ppm, KAS will collect post-excavation confirmation soil samples. This will include four sidewall samples and one bottom



sample for a total of five samples. The samples will be stored on ice and transported to EAI for analyses of the following analytes:

• VOCs by EPA Method 8260; • TPH by EPA Method 8100; • PAH by EPA Method 8270; and, • RCRA 8 Metals.

The excavations will be backfilled with a combination of clean overburden (no visual/no olfactory/PID <10 ppm) and delivered clean fill. Backfill will be compacted with a plate compactor or similar equipment via two-foot intervals. The area will be seeded and mulched to replace the surface in kind. CAPPING OF SHALLOW CONTAMINATED SOILS (AOCS #2, 3 AND 4) AOC 2, 3 and 4 will be covered with filter fabric and 12 inches of clean fill. The fill will be material derived from the on-site sand pit and will be suitable for its intended purpose. The fill will be compacted with a plate compactor or similar equipment. A layer of topsoil will be placed and the surfaces will be seeded and mulched to replace in kind. NOTICE TO LAND RECORDS KAS will prepare a draft Notice to the Land Record for approval by the Town and the DEC for areas where

contamination will remain, including AOCs #2 through 6. The notice will include a site map depicting the areas where the soil caps were installed and the UST area where petroleum contamination remains in the ground. MONITORING WELL REPLACEMENT AND TESTING It is anticipated that monitoring wells MW-16 and MW-17 will be destroyed during soil removal in AOC #1. KAS will oversee the installation of one replacement well MW-16R. The well will be installed utilizing a hollow stem auger and will consist of 2-inch PVC well material with a 10 foot screen section set to span the water table. The well will be 30’ deep. The screen section will be surrounded by sand pack and a bentonite seal will be placed above the screen, followed by native backfill. The well will be completed with either a flush mounted road box or a locking standpipe, developed and surveyed relative to the established site reference. Approximately one week following installation, all existing monitoring wells and the replacement monitoring well (21 wells) will be sampled for VOCs by US EPA Method 8260 and total 8 RCRA Metals as above. The monitoring wells will be sampled with bailers. The on-site supply well will also be tested for VOCs by US EPA Method 524.2.



COMPLETION REPORT Following completion of the work Daly and KAS will prepare a completion report documenting the work performed. Specifically the report will include:

• Quantities of waste removed. • Surveyed locations of excavation

(AOC 1) and cap edges (AOC 2, 3 and 4).

• Laboratory testing results. • Bills of lading for off-site soil

disposal. • Hazardous waste manifests

(drummed waste including floor drain and drywell sludge).

• Groundwater maps. The report will be certified by the appropriate environmental professionals and will be submitted to the Town for review before being sent to the DEC for review. 2.3 Laboratory Data Validation/Verification Following receipt of laboratory analytical data and laboratory quality assurance information, KAS’ quality assurance officer (QAO) will perform data verification /validation as described in the QAPP. The verification will evaluate the usability of the data generated during the investigation including soil laboratory

analytical data, and will determine whether data quality objectives (DQO) are met. Parameters to be evaluated will be described in the QAPP. The QAO will prepare a data verification report that notes whether DQOs are met, and will opine as to whether the data generated during the investigation are usable for the intended purposes. 2.4 Report Preparation and Submission A Brownfields Cleanup Completion report will be prepared for review and approval. The report will be approved and signed by an environmental professional. A description of the methodologies and results will be included as will a list of deviations from the approved QAPP document, if any occur. Comparison with appropriate environmental and materials quality standards will be made, as indicated in Section 1.4. Also, the Brownfields report will contain: a site map, sampling locations; laboratory analytical data and data validation report; conclusions; and other recommendations, as applicable.

DATA VALIDATION REPORT

Data Validation Report Former Crawford’s Autoland, South Royalton, Vermont

01/16/2014 KAS Project No. 510130318

Project Description Summary This data validation report applies to subsurface soil vapors at the Former Crawford’s Autoland, South Royalton, Vermont (DEC SMS#2011-4190; Site). Samples were collected using the scope of work according to the approved Brownfields Site Specific Quality Assurance Project Plan (QAPP) Addendum dated October 23, 2013, amended November 7, 2013. Sampling occurred on November 14, 2013 and December 5, 2013. Laboratory analysis of samples was performed by Eastern Analytical, Inc. of Concord, New Hampshire. Please refer to the QAPP addendums for additional details concerning the site background, work scope, and standard operating procedures. The following specific data were validated:

Five soil samples were analyzed for volatile organic compounds (VOCs) via EPA method 8260B, semi-VOCs (SVOCs) via EPA method 8270, RCRA metals via EPA method 6020, and total petroleum hydrocarbons (TPH) via EPA method 8100mod;

Four stockpiled soil samples were analyzed for VOCs via EPA method 8260B, SVOCs via EPA method 8270, total metals via EPA method 6020, TPH via EPA method 8100 mod, polychlorinated biphenyls (PCBs) via EPA method 8082, ignitability via EPA method 1030, pH via EPA method 9045, reactive cyanide via EPA method 7.3.3.2, and reactive sulfide via EPA method 7.3.4.2;

Eleven groundwatersamples were analyzed for VOCs via EPA method 8260B and total RCRA metals via EPA method 6020; and,

One drinking water sample was analyzed for VOCs via EPA method 524.2.

The following is an overview of the various methods by which quality of laboratory data is assessed. These parameters are used to ensure that acceptable criteria of accuracy and precision are met, to ensure that any bias in reporting is below acceptance criteria, and that proper calibration of equipment has been performed.

Sampling Procedures and Protocols Sampling was performed in accordance with the procedures specified in the QAPP. Field data sheets and the field notebooks were

reviewed to ensure proper documentation of the sampling conditions. All entries were made with permanent ink. Entries included the initials of the sampler, sampling location, time, and date. All entries and equipment used were recorded on the daily work report. The chain of custody forms were reviewed to ensure the sample identification, number, type and size of sample containers, preservatives used; and signatures were properly recorded and were in accordance with the requirements of the QAPP. The laboratory was able to analyze these samples in accordance with the standard procedure. All samples arrived at the laboratory and were analyzed within EPA holding times.

Blanks Blanks measure the influence of outside factors on reported results, and field blanks, trip blanks, and method blanks all target specific factors in the sampling process. Field blanks are used to ensure that proper decontamination procedures are followed in the field, and trip blanks are to ensure that no outside contamination resulted during transit to the lab. Method blanks are laboratory prepared blanks of pure water or sand which are analyzed with the batch of samples to ensure that there is no contamination resulting from the laboratory handling of samples or the analysis procedures. All blanks were prepared for all analyses performed and reported no detection of compounds, indicating that there was no contamination of samples.

MS/MSD and LCS/LCSD Matrix spike/ matrix spike duplicate (MS/MSD) and laboratory control samples/ laboratory control sample duplicate (LCS/LCSD) analysis measure accuracy, which is a way to ensure that reported results are close to the actual concentrations of the tested compounds within the sample. To ensure that the matrix of the sample, i.e. soil, is not interfering with results, a matrix spike analysis is conducted. Laboratory instruments are calibrated using solutions of known chemical makeup and concentration, so to test the effectiveness of the particular analytical method on the parent material, a known concentration of the contaminant of interest (or spike) is added to the matrix and analyzed. The laboratory control sample (LCS) is similar in that a known concentration of a chemical is added to a solution, but in this


01/16/2014 KAS Project No. 510130318

instance it is a sample prepared in the laboratory of pure water. This is to test the effectiveness of the analytical method independent of the matrix. LCS for VOCs aqueous drinking water sample was not within laboratory QA/QC limits of 70% - 130%. However, the laboratory results reported non-detect levels of VOC compounds making the data adequate.

RPD One way in which quality of data is measurable is by calculating the relative percent difference (RPD) between the sample and duplicate. RPD values assess the precision of reported values, which is indicated by a high degree of reproducibility of results. The RPD is defined as 100 times the difference between the sample result and the duplicate result, divided by the mean of the sample and duplicate result. RPD values are also calculated to assess the difference between the matrix spike and matrix spike duplicate as well as the laboratory control sample and the laboratory control sample duplicate. All soil analyses included a duplicate. Barium in soil sample Westhad a reported RPD of 81%, higher than acceptable range; however, the reported values were significantly below the designated IROCP standards. The sample results should be included for compounds have the potential to vary between soil samples. All other RPD values were reported below 50% indicating good precision.

Surrogate Recovery Surrogate recovery is measured when a compound of known quantity and concentration is added to the sample and then analyzed using the same standard method and the percentage of the compound recovered is reported. This is a way to test for bias in the analysis. If there is a low percent recovery concentration it can be deduced that other tested compounds may also be reported low, and conversely the same is true if the percent recovery is high. Surrogate recovery was performed for all analyses, excluding groundwater well samples analyses for metals. For all surrogate recovery analyses performed percentages were within the QAPP specified ranges, indicating accuracy in that the reported results are likely representative of the actual concentrations contained within the samples.

Reporting Limits Laboratory reporting limits were compared with applicable Form K criteria for each tested compound to ensure that laboratory analysis is relevant to the concentrations at which contaminants are of concern. For soil VOC analysis the compounds vinyl chloride, 1,2-Dibromoethane, 1,2,3-Trichloropropane, and 1,2-Dibromo-3-chloropropane had detection limits above the IROCP. For aqueous VOC analysis the compounds Bromodichloromethane, cis-1,3-Dichloropropene, trans-1,3-Dichloropropene, Dibromochloromethane, 1,1,2,2-Tetrachloroethane, and 1,2-Dibromo-3-chloropropane had detections limits above the VGES.

Completeness/Deviations The data validated in this report pertains to section 2.2 Designated Field Work Tasks of the Brownfields Site Specific Quality Assurance Project Plan (QAPP) Addendum dated October 23, 2013, amended November 7, 2013. The soil and aqueous samples were collected following procedures outlined in the QAPP and there were two deviations to note.

Ignitability, pH, reactive cyanide and reactive sulfide analysis were performed on the soil for disposal as required per the disposal facility requirements.

Various groundwater monitoring wells were unable to be sampled due to the wells being dry or insufficient water. It appears that the wells that were sampled provide adequate delineation of compounds in the groundwater at the Site.

Conclusion Based on the findings presented above, all data (soil and aqueous) should be accepted without condition.
