INTRODUCTION The North Elmore Chevron facility is located at 1200 Alabama Highway 14 in Elmore, Alabama.

Topographically the site is an area of moderate relief in southwestern Elmore County. The site is

in the northeast ¼ of the southeastern ¼ of the southwestern ¼ of Section 12, Township 18 North,

Range 17 East. The geographical coordinates are Latitude 32° 33’ 26.42” North, Longitude 86°

19’ 8.21” West (Figures, Appendix B).

SITE HISTORY The North Elmore Chevron has served as a convenience store and filling station in Elmore,

Alabama since its construction in 1969. The site contains two 6,000 gallon and two 4,000 gallon

Underground Storage Tanks (USTs). Interstate Oil Company is the owner of the USTs and is the

responsible party for the release incident number UST11-06-10.

In May 2011, Interstate Oil Company, Inc. had a Limited Phase II Environmental Site Assessment

(ESA) performed at the North Elmore Chevron as required for a pending real estate transaction. The soil and groundwater samples collected during the Limited Phase II ESA indicated soil and

groundwater constituent concentrations that were above ADEM’s Initial Screening Levels (ISLs).

ADEM was notified of the findings from the Limited Phase II Environmental Site Assessment. On

July 19, 2011, ADEM responded with a letter requiring Interstate Oil Company to Conduct

Investigative and Corrective Actions. In a second letter, ADEM stated that the North Elmore Chevron was eligible under the Alabama Tank Trust Fund (ATTF). In a third letter, ADEM issued

a Pre-approval for a Preliminary Investigation activity requiring that a Preliminary Investigation

be conducted at the site.

SUMMARY OF PREVIOUS SITE ACTIVITIES The Preliminary, Secondary, and Supplemental Secondary Investigations, and Well Installations

have included installing a network of nineteen Type II monitoring wells, one Type III vertical

delineation well, and three 4” recovery wells. An ARBCA Tier I/Tier II Evaluation was prepared

and submitted to ADEM in October 2012 and was approved by ADEM on December 5, 2012. A

Corrective Action Plan (CAP) was prepared in June 2013 for Remediation by Natural Attenuation

(RNA) with MEME events and was approved by ADEM on February 11, 2013.

2

To date, twenty groundwater monitoring events have been conducted at the site between

August 2011 and October 2017. Additionally, three 24-hour Mobile Enhanced Multiphase

Extraction (MEME) events were conducted between April 2013 and October 2013 and thirty-six

8-hour MEME events were conducted between February 2014 and September 2017.

The effectiveness of the MEME events at the North Elmore Chevron site was discussed during a

meeting with ADEM on September 6, 2017. Due to the accumulating costs and disruptions to

the business, CDG recommended that an available Multi-phase Extraction (MPE) system,

currently in operation at an Interstate Oil Company, Inc. ATTF site in Montgomery, be relocated

to the North Elmore site. The MPE system owned by Interstate Oil Company, Inc. was recently

shut down at their Atlanta Highway site (UST11-06-11). This system could be relocated to the

North Elmore site at a significant cost savings as compared to purchasing a new one. The benefits of a dedicated system include increased remediation effort, less impact to the site’s business,

and significant long-term cost benefits.

Upon review, ADEM requested that a Modified CAP be completed for the relocation and

installation the dedicated MPE system at the North Elmore Chevron site.

PURPOSE The purpose of this report is to modify the existing CAP to enhance the remedial efforts at the site. As discussed in a meeting with ADEM on September 6, 2017, a more aggressive remediation

approach is warranted due to the persistence of COC concentrations at the site. The general

objectives of this modified corrective action plan and the proposed remedial efforts for the facility are as follows:

• Ensure that the health and safety of all project personnel is maintained during

remediation activities.

• Enhance the reduction of absorbed phase petroleum hydrocarbons from soils within the

vadose and saturated zone to below the accepted SSTLs.

• Enhance the reduction of dissolved phase petroleum hydrocarbons from groundwater to

below the accepted SSTLs.

• Accomplish these objectives within the proposed period of operation.

3

REMEDIATION RECOMMENDATION PLAN The proposed corrective action includes:

• The installation of four additional recovery wells that will be used in conjunction with the

existing recovery wells for full time MPE recovery efforts;

• A MPE system that is currently in present at the Interstate Oil Company ATTF site, Atlanta

Highway (UST11-06-11), which will be relocated to the North Elmore Chevron site;

• All recovery wells will be connected to the MPE system via underground piping;

• Application for NPDES permit and Air permit.

Well Installation CDG recommends installing four recovery wells. The borings will be completed with a truck

mounted drill rig using hollow stem auger drilling and sampling techniques to depths of approximately 25 feet bgl. As the borings are advanced, soil samples will be collected using

continuous sampling techniques to accurately describe the encountered sediments. The borings

will be sampled using 5-foot split spoon samplers advanced through the augers. The samplers

and augers will be decontaminated between borings.

Based on field head space screening, using a Photo Ionization Detector (PID), two (2) soil samples

will be selected from each boring and placed in two 4 oz. jars with Teflon lids, packed on ice, and shipped under chain-of-custody protocol, to an analytical laboratory for

BTEX/MTBE/Naphthalene analysis using EPA Method 8260B.

The soil borings will be completed as Recovery wells RW-4 through RW-7 as shown in the Figures

in Appendix B. The Type II recovery wells will be emplaced to a depth of approximately 25 feet

bgl. The wells will be constructed of 4-inch PVC pipe with 15 feet of 0.020-inch slotted PVC screen. Graded filter sand (10/20) will be emplaced around the screen, and a bentonite pellet

seal will be emplaced above the sand pack. The remainder of the annulus will be sealed with a

cement grout mixture. A locking watertight cap will be placed in the top of each well, and a

protective casing with a bolt down cover will be installed over the casing in a flush mounted

concrete pad. A typical Type II recovery well construction is shown in the figures (Appendix B).

Following completion, each of the newly installed recovery wells will be developed using a new,

clean plastic bailer until clear, silt free water was being produced. Purge water will be placed into

4

the MPE system for treatment and discharged under the NPDES permit. The proposed locations

of the wells are shown in the figures (Appendix B).

System Detail and Installation The proposed MPE system will utilize a single 40-HP oil-sealed liquid ring vacuum pump (LRVP)

to produce high vacuums and airflows in an effort to remove petroleum constituents from the

impacted subsurface. The LRVP will be connected to a total of six recovery wells (RW-1, RW-2,

RW-4, RW-5, RW-6, and RW-7). All system components, excluding air treatment operations, will

be enclosed in an insulated building with removable panels. Above ground system components

will be enclosed in a wooden privacy fence complete with locking gates in an effort to prevent

unauthorized personnel from entering the immediate area. The fence will be placarded with a

sign listing CDG’s emergency contact information.

Extracted fluids will travel from the extraction wells to a primary Air/Water Separator (AWS),

utilized to separate vapors and groundwater. Vapors will subsequently pass through the LRVP to

two 1,000-pound granular activated carbon vessels, connected in series. Groundwater will flow

from the AWS through an oil-water separator (OWS) to an air stripper (AS) for treatment. The AS is capable of decreasing hydrocarbon concentrations to below permit requirements at flows up

to thirty gallons per minute (gpm). The treated effluent will be discharged under the terms of the

general National Pollutant Discharge Elimination System (NPDES) permit to the surface drainage along Highway 143. A 2-inch diameter discharge line will be installed from the system compound

to the discharge point. The discharge will be sampled monthly and the discharge monitoring

reports (DMRs) submitted to ADEM in accordance with the permit requirements.

An illustration of the locations of the recovery wells, flow lines, effluent discharge and proposed

system location is shown in the figures (Appendix B). Equipment specifications and cut sheets

are provided in Appendix D.

Additionally, the system will be outfitted with an intrinsically safe alarm sensor such that should

an alarm condition occur, the system will automatically shut down until the alarm can be relieved

and the system reset. These sensors are included in an effort to maintain effective operation of

the system and reduce the potential for untreated discharges. The alarms will be integrated with

a telemetry system to notify CDG of a system fault, so that it can be restarted as soon as possible.

The telemetry system will allow CDG to remotely restart the system, depending on the type of

5

alarm. In addition, remote shut down capabilities will be available. A run time (hour) meter will

be installed on the system and the system will be equipped with applicable gauges and meters

to allow for measurements as required for monthly and/or quarterly reporting.

Each recovery well will be connected to the DPE system via underground piping consisting of 2-

inch ID Schedule 40 PVC pipe. A one-inch diameter flexible Spiralite® drop tube, extending to

approximately one foot below the static groundwater level, will be installed in each extraction

well to accomplish soil vapor and groundwater recovery. A dedicated flow line will be

constructed to each well and will be terminated at the system within a well control gallery

consisting of a ball-valve, vacuum gage, and site glass to allow for control and monitoring of the

flow from each well. The proposed recovery well locations and piping network, along with a

typical recovery well detail and an illustration of the well control gallery construction is shown in the Figures (Appendix B).

Local Permitting CDG and any subcontractors engaged to work on this project will obtain all necessary permits

from the City of Elmore for the required construction activities. The anticipated cost for obtaining these permits has been factored into the proposed cost for the system installation phase of this

project.

Groundwater Monitoring Groundwater samples will continue to be collected quarterly from all site monitoring wells. The

groundwater samples will be collected from the monitoring wells using new clean plastic bailers

and transferred to 40 milliliter (mL) glass volatile organic analysis (VOA) vials preserved with

hydrochloric acid (HCl) for BTEX, MTBE, and Naphthalene analysis using EPA Method 8260B.

During each groundwater sampling event, all monitoring wells will also be monitored for natural

attenuation parameters (DO, pH, and ORP).

PROPOSED REPORTING REQUIREMENTS CDG will submit reports in accordance with ADEM requirements. These reports will include the

following:

6

System Installation Report - This report will include the recovery well installation details, system

installation details, and application/approval of the NPDES permit.

Reporting of Quarterly Operation and Maintenance Events Effectiveness - CDG proposes to

submit quarterly CASEMR reports, which will summarize system and field activities and the

progress of site groundwater constituent concentrations towards achieving approved corrective

action levels. The following data will be included in each report: field activities performed,

groundwater elevations, groundwater analytical results as compared to target levels,

potentiometric surface maps, BTEX/MTBE contour maps, pounds of hydrocarbons removed in

the vapor and liquid phase, and gallons of water treated. The reports will also include

remediation effectiveness and recommendations concerning additional measures deemed

necessary.

Request for Closure Evaluation of Corrective Action - This report will include data that

demonstrates that remediation goals have been achieved and will request a status of No Further Action (NFA) for the site. Methods for abandonment of monitoring and recovery wells will be
