Everett Director ERRL-0119-25 March 21, 2025 CERTIFIED MAIL RETURN RECEIPT REQUESTED Harpreet Happy Singh RAMDAS JI Hyrum, LLC 580 West 3600 South Nibley, Utah 84321 Raghunandan Singh RAMDAS JI Hyrum, LLC 11327 South Pervenche Lane South Jordan, Utah 84095 Re: Abatement, Subsurface Investigation and Corrective Action Plan Requirements Former Manning Short Stop Amoco, located at 325 West Main Street, Hyrum, Utah Facility Identification No. 0100519, Release Site ONA Dear Messrs. Singh: A release of petroleum from a petroleum storage tank (PST) at the above-referenced site was reported on March 14, 2025, to the Division of Environmental Response and Remediation (DERR) based on petroleum odors and sheen on waters within the Hyrum City storm drain system and traced back to the gas station fuel tanks. According to Utah Administrative Code R311-202, as the property owner and Responsible Party, you are required to report, control, abate, and characterize the release by defining the extent and degree of petroleum contamination and remediate (clean up) the release. These regulations require that you prepare specific reports addressing the release and submit them to the DERR within specified time frames following the release. The DERR project manager has reviewed the release report information and has recommended that continued abatement and further investigation and cleanup work is required. The project manager relied on the information provided and did not conduct an independent investigation of the facility. In conjunction with Utah PST rules, the DERR is requesting: 1. Continued abatement of the impacted storm drain system and surface waters; 2. Secure the out-of-use PST so future fuel delivery errors or releases cannot occur; 3. Abate impacted soils and/or free product at the aboveground PST compound; 4. Stop the continued leaching of petroleum from the soils at the PST compound into the groundwater and surface waters; Facility ID# 0100519 Page 2 5. Submit a Closure Plan and get approval from the DERR prior to the removal of the three older aboveground PSTs for the removal of impacted soil, product and groundwater beneath the tanks; 6. Investigate and delineate the nature and extent of petroleum impacts to the soil and groundwater outside the current aboveground PST compound; 7. Comply with any additional requirements of the Division of Water Quality (initial email, dated March 18, 2025, is attached); and, 8. Prepare and submit a Corrective Action Plan to remediate any residual petroleum impacts to soil, groundwater, or surface waters/storm drains that may remain following steps 1 through 7 above. If you hire a consultant to perform work related to this release, they must be a Certified PST Consultant (Utah Admin. Code R311-201-2). All environmental samples must be collected by a Certified Groundwater and Soil Sampler. Lists of currently certified persons are attached. Cleanup levels for your site will be established using the criteria and standards required by Utah Admin. Code R311-211, and as described in the DERR guidance. An Abatement Report covering items 1 through 4 above should be submitted to the DERR within 30 days of completing those activities. A detailed description of the abatement activities should be presented in the report, including the results (volumes of product recovered from various methods, volumes of water or soil removed, any confirmation sample data, lab reports, photos, contractor’s daily logs, etc.). The tank Closure Plan (item 5) should be submitted as soon as possible for the DERR approval. Closure approval allows for the removal of up to 50 cubic yards of impacted soil. A written request for authorization to remove more than 50 cubic yards must be submitted and approved bytheDERR before additional impacted soils can be excavated and removed. This request must include an estimate of the additional amount of soil to be removed. Copies of the Closure Plan form and the follow-up Closure Notice form are attached. The final Closure Notice must be submitted to the DERR within 90 days after the tank removal. The intent of performing the investigation (item 6) is to define the extent and degree of any remaining subsurface petroleum contamination and evaluate the potential risks to human health and the environment. A Subsurface Investigation Report (SIR) outlining the results of the investigation must be submitted to the DERR within 120 days of your receipt of this letter. Additionally, as outlined in Utah Admin. Code R311-202, Sections 280.66 and 280.67, a Corrective Action Plan (CAP) may be necessary to clean up any residual contamination at your site (item 8). After the previously mentioned reports have been received and reviewed, the DERR will evaluate if a CAP, or other work, is necessary for this release. The DERR will review any CAP for approval based upon an evaluation of the cleanup plans for the protection of human health and the environment, cost effectiveness, and use of appropriate cleanup technology. Requirements and guidance for an SIR and for a CAP can be found in the DERR guidance documents attached to this letter. All environmental samples must be analyzed for gasoline and diesel compounds, as outlined in the Analytical Methods table in the SIR Guide. Facility ID# 0100519 Page 3 Section 19-6-420(10)(a) of the Underground Storage Tank Act was amended to allow the DERR to recover certain expenses incurred by the DERR for petroleum releases not covered by the PST Fund. The DERR’s expenses for managing and overseeing the abatement, investigation or corrective action can be billed on a quarterly basis to the responsible party. These expenses will be billed at a rate set by the Utah Legislature for oversight and review, which is currently $125.00 per hour. Payment will be due within 30 days from the billing. Certain factors may be considered by the Division Director when determining whether to recover these management and oversight costs. If the Responsible Party can demonstrate an inability to pay, the Division Director may grant an exemption from paying these expenses. You may contact us to request an application for exemption, if needed. If you have any questions regarding this matter, please contact Eileen Brennan, the DERR project manager, at (801) 536-4100. Please keep the DERR project manager informed, in advance, of field activities and other critical tasks. Sincerely, Brent H.

May 2014 A petroleum release has been confirmed at your facility, and screening levels have been exceeded. You are therefore required to investigate and remediate the release. This publication will guide you through the process of preparing the Subsurface Investigation Report as required under the state-established compliance schedule( s) for releases of petroleum products from underground storage tank (UST) systems. A subsurface investigation, to define the extent and degree of contamination, is required in order to establish site-specific clean-up levels prior to consideration of closing the release site. This Subsurface Investigation Report replaces the former versions known as the "Abatement and Initial Site Characterization Report" and the "Subsurface Investigation Report", formally required under the "Phase I" and "Phase II Reporting and Remediation Schedules". The "Corrective Action Plan Report" has been replaced by the "Corrective Action Plan Guide." The former reporting formats should be discontinued immediately.

Page 2 The answer to these questions can help get you started Subsurface Investigation and Clean-up Checklist The following checklist will provide you with a summary of the steps between discovery of a petroleum release, investigation and remediation (clean-up) of your release and final site closure. It is designed to help you understand the steps involved, to graphically track your progress, and show how near to completion of the process you are. X Important Steps to Remember Report the release within 24 hours of discovery to the Division of Environmental Response and Remediation (DERR). Stop the source of the release and prevent the spread of further contamination. If the leak or release occurred from a tank that is covered by the Utah Petroleum Storage Tank Trust Fund (FUND)*, submit an Eligibility Application for reimbursement of investigation and clean-up costs. Refer to the DERR's publication "Petroleum Storage Tank Fund Claims Packet" for complete eligibility and reimbursement information. Prepare and submit a "Subsurface Investigation Report" within 90 days of notification from the DERR. Use this guide for preparing the report.** If free product is found, prepare a "Free Product Removal Report" and include it with your Subsurface Investigation report. Use this guide for preparing your Free Product Removal Report (page 9). Refer to the APermitting Requirements List; contained in this guide (page 10) for any applicable reporting or permitting requirements by other regulatory agencies for the release at your facility. Submit a "Corrective Action Plan", as requested by the DERR, to clean up contamination to established or recommended clean-up levels, or conduct a risk assessment to establish site-specific clean-up levels. Once work or clean-up at the site is completed as determined by the DERR, request site closure in the form of a "no further action" letter from the DERR. Frequently Asked Questions Why do I have to submit a Subsurface Investigation Report? There are two reasons why you must submit this report to the Utah Division of Environmental Response and Remediation (DERR). First, you are required by Utah law to report, control, abate and characterize the release by defining the extent and degree of contamination, and conduct remediation (clean-up) if necessary. And second, it will enable the DERR to help guide you through the investigation and clean-up process to make it as timely, site-specific and cost effective as possible. If information regarding your release site indicates relatively high levels of petroleum contamination, further investigation will help determine if there are risks of contaminating drinking water, indoor air, surface water, sensitive wildlife habitats or other sensitive receptors. This report provides information to help determine these potential risks. *Even if the tank is not currently on the Fund, the release may be covered by the Fund if the release occurred while the tank was on the Fund and if the tank was on the Fund within the last six (6) months (or one year in some circumstances). If there is any possibility that the release is covered, the eligibility application should be submitted immediately because the claim will be ineligible ifit is not submitted on time. See Utah Code §19-6-424. **Depending on the results of your subsurface investigation, more work may be needed at the release site. This additional work may consist of conducting groundwater monitoring, abatement or cleanup activities, additional investigations or other related Subsurface Investigation Report Guide Page 3 work. Should I hire a consultant? Utah law requires that starting on January 1, 1996, contractors or environmental consultants must be certified as a "Certified UST Consultant" to perform work at any UST release site. You will need to hire the services of a trained and experienced environmental consultant or contractor to assist you with necessary abatement, investigation and clean-up work and associated reports. Environmental professionals with experience in leaking underground storage tank (LUST) site investigations and clean-ups are available to help you with this work in a timely and cost effective manner. It is in your best interest to get several competitive bids before beginning the work. The DERR has a list of contractors and certified consultants available upon request. The State of Utah does not endorse any consultant or company, but maintains this list of contractors who have indicated an ability to perform the required work for your benefit. When do I submit the report? A Subsurface Investigation Report is due 90 days after receiving this guide from the DERR. Please contact your project manager with any questions regarding your release site or the required report. How do I file the report? Submit your Subsurface Investigation Report to your DERR project manager at: Utah Department of Environmental Quality Division of Environmental Response and Remediation Leaking Underground Storage Tank (LUST) Section 195 North 1950 West P.O. Box 144840 Salt Lake City, Utah 84114-4840 (801) 536-4100 You can deliver or submit the report in person to this address or you may send it by mail. What information should the report contain? The remainder of this guide contains the information necessary for putting together the Subsurface Investigation Report. If you use this guide and include the specific information detailed in it, your report will be complete and will minimize the DERR's review and response time. Also, a complete report will help minimize any additional expense or time on your part for the collection of additional data and information. Subsurface Investigation Report Guide Depending on the scope of work to be done at your release site, you may need to use a state-certified environmental consultant. Page 4 Create an at-a- glance summary of your report. A table of contents can work as a checklist assuring the report is complete. Your introduction should include general information about the site. A picture is worth a thousand words. Prepare a good site map! COMPONENTS OF THE SUBSURFACE INVESTIGATION REPORT Executive Summary The Executive Summary is a brief summary of this report.

Be sure to include depth ( feet below grade) of sample collection. • Location of soil stockpiles, aeration piles, etc. • Land features surrounding the site including; lakes, rivers, streams, irrigation canals, wetlands, slope of local land surface, etc. Identify all sample locations shown on your site map. Make sure your sample numbers and locations are consistent with the identification labels used on the chain-of-custody forms and the laboratory analytical reports. If the site map becomes cluttered or confusing due to a large number of sample identification labels, you may wish to use more than one sampling map, or use other techniques to identify the sample locations. You may also include additional site maps showing contaminant iso- concentration contours, geologic cross sections and groundwater elevation contours. You should also present the sampling results in a table format so sample data can be easily referenced to the sample locations marked on the site map. 3 Tier 1 Criteria This section "Tier 1 Criteria", describes the environmental features and possible risks to human health or the environment at the release site. These features help to determine risks presented by your release site and its classification status. Site classification is a dynamic process for prioritizing release sites according to the seriousness of the release. The corresponding response action needed is based on the current and potential degree and severity of hazards to human health or the environment. This process is evaluated on a case- by-case basis and ensures that when maximum contaminant limits are exceeded, appropriate response actions are taken to protect human health and the environment. Site classification is based on the most recent data and reflects current site conditions. Since the risks posed by contamination at any given release site are expected to change as more information is learned about a site, a site may be re-classified. Please provide the following information: • • • • Describe the current land use at, and surrounding the release site. It is considered residential if a residence is located on, or adjacent to your site in any direction. Describe the naturally occurring soil type and the depth and location where the samples were obtained. Unified soil classification (USC) is preferred; however, a geologic field description is acceptable ( e.g., gravel, sand, silt, clay, etc.), if done by a qualified person. Indicate if you encountered groundwater at your site during UST closure, investigation activities, or obtained groundwater information from other sources. If so, indicate the groundwater depth (in feet) below the ground surface at or near your site. Groundwater flow direction can be determined if you have at least three (3) groundwater monitoring wells properly installed at your site. You may also be able to determine groundwater flow direction from other wells installed at a nearby LUST release site. Describe which method you used to determine groundwater flow direction. Subsurface Investigation Report Guide Tier 1 Criteria affects the clean- up level and subsequent closure of your site. Be as accurate as possible. Your site classification will help determine if immediate response actions are needed. Page 6 Site classification is a dynamic process and can change as more information is obtained. Identify the product released and describe where the leak occurred. Have you stopped the release to minimize future problems? On-or off-site soil treatment such as aeration or land farming needs approval from more than one regulatory agency. Don't forget to take corifirmation samples! 4 • • • Indicate the distance and estimated depth (in feet) below grade from the source area of petroleum contamination to the following buried utilities; water line, sanitary sewer, natural gas, storm drain, telephone, electrical, other (specify). Indicate the distance (in feet) from the source area of petroleum contamination to property lines and buildings (indicate type of building; residential, commercial, industrial, etc.). If available, document the water well survey ( e.g., Points of Diversion Information) conducted at the release site. Nature of the Release and Abatement Measures In this section, you provide details about the release, including age, condition and contents of the UST. You are also required to perform and report abatement measures to stop the source of contamination and to prevent further releases of contamination. Describe the following: • • • • • Age and condition of the UST system, including piping and tanks, corrosion holes, soil staining or odor, sheen on surface of groundwater or surface water. Types and amount ofproduct(s) stored in the USTs, and the type and estimated amount of product released into the environment. Cause and location of the release such as the tank, dispenser island, piping, overfills and spills, etc. The method(s) used for detecting contamination . The location of where the contaminated soil or groundwater was either properly disposed of, or is currently being stockpiled or stored. All stockpiled or aerated soils should be managed in accordance with the DERR'S "Guidelines for Disposition and Treatment of Petroleum-Contaminated Soils". Prior to aeration, approval must be obtained from the local health department, the Utah Division of Air Quality and the DERR. Contact your DERR project manager for assistance with these aeration requirements. • If contaminated soils are overexcavated, or if groundwater is removed from the release site, confirmation soil or groundwater samples must be taken to confirm that the levels of contamination remaining in-place are at or below established clean-up levels. • Determine the total volume, contaminant type(s) and concentration(s) of the removed groundwater or soil, and any soil or groundwater contamination remaining in-place. • Determine the volume, concentration and disposal method or location used for well development or purge water, groundwater, excavation water or other waste water, etc. • Collect representative environmental samples (soil, groundwater, etc.) to define the nature, extent and degree of the contamination at the site. Information regarding the results of the investigation and plans for future work, if any, should be included in the "Conclusions and Recommendations" section of the report. • Consult with your DERR project manager or your environmental consultant prior to any confirmation sampling. There may be site-specific requirements necessary for site close-out. See "Sampling Procedures and Requirements" (page 11) for general descriptions of analytical testing requirements for various types of petroleum contamination. IMPORTANT: You must IMMEDIATELY begin removal of any free petroleum product in excess of 1/8 inch thick. Refer to the enclosed Free Product Removal Report (page 9) for more ieformation. Subsurface Investigation Report Guide Page J 5 Methodology This section describes the methods and procedures used to conduct the investigation and should include the following: • • • • • Document that all the proper agencies have been contacted and that all necessary permits or approvals have been obtained. Refer to the list of agencies in the "Permitting Requirements List" (page 10) to determine if you need their involvement or approval. Describe all methods of investigation used to define the extent and degree of soil and groundwater contamination. This may include on-or off-site soil borings by drilling or direct-push methods, groundwater monitoring wells, soil vapor surveys, overexcavation, test pits, etc. Describe each of the following for all groundwater monitoring well installations: Method of drilling or other types of placement of wells ( such as digging, backfilling or direct-push techniques).

Describe method used for purging wells, and how many well casing volumes (total number of gallons) were purged from the well(s). Describe how the SWL measurement was determined. Explain how purge, development or rinsate water generated from wells was disposed. These descriptions, methods and rationale are generally referred to as your "standard operating procedures" (SOP's). If your SO P's don't substantially change between different sampling events and reports to the DERR, you don't need to describe them again. Simply refer to the previous report. Subsurface Investigation Report Guide Do you need to notify any other regulatory agencies? Refer to the Permitting Requirements List to see if you do. You may need to obtain off-site access agreements to determine the fall extent and degree of soil and groundwater contamination. Describe how the subsuiface investigation was conducted You may need to conduct quarterly monitoring for a year or so to determine trends in flow direction, contamination levels and depth to groundwater. Page 8 Describe the results obtained from your subsurface investigation which should define the extent and degree of soil and groundwater contamination. Refer to "Sampling Procedures and Requirements" in the Additional Information and Resources section at the end of this guide.

NOTE: The sample preparation method and any modification(s) to a certified method must be reported by the laboratory. Page 13 Subsurface Investigation Report Guide Be sure to check with your DERR project manager or your environmental consultant if you have any questions regarding your sampling program or corrective action plan requirements. Some suggestions or ideas to consider when developing your sampling, operation or maintenance plan may include: Take both types of samples ( e.g., soil and groundwater) if groundwater was encountered during the course of soil sampling. Take two or more soil samples in selected locations to better define the vertical extent of contamination. This data will aid in clean-up or closure evaluations. Conduct continuous sampling of soil boring(s) or collect multiple samples per location to better define the native soil type, contaminated interval or vertical profile, geological features and related items. Upgrade your analytical method(s) to get more complete information during the initial sampling events and minimize re-sampling events. Have enough budget set aside to be flexible in the number of actual samples submitted for laboratory analyses, or the number of soil borings or groundwater monitoring wells drilled, etc. Check with other regulatory agencies to ensure sampling meets with their requirements for waste disposal or other related items. Obtain any necessary off-site access agreements or highway easements for potential work outside your property boundaries in determining the extent and degree of subsurface soil and groundwater contamination. For vapor, air, or any other type of environmental sampling, determine the appropriate analytical method and sampling procedures prior to field collection.

A separate guide is used for PST funded sites. Cleanup levels (Attachment A) for LUST sites will be established using the criteria and standards required by Utah Admin. Code R311-211, in order to protect human health and the environment at the release site, and other impacted areas. Depending on site conditions, initial screening levels (ISLs), Tier 1 Screening Levels, or site-specific cleanup levels are used for appropriate cleanup standards. A CAP describes the cleanup method selected to cleanup a LUST site to the established cleanup levels. After the nature and extent of a release has been defined, the Division of Environmental Response and Remediation (DERR) will require a CAP. The CAP must be approved by the DERR prior to implementation. The DERR evaluates a CAP based on: • A discussion and comparison of all applicable and appropriate cleanup methods • The technical and economic feasibility of each method • The ability of the cleanup method selected to achieve cleanup standards 1. Corrective Action Plan Meeting A CAP meeting with the LUST project manager (PM), Responsible Party (RP), Certified UST Consultant, and property owner is recommended prior to preparing a CAP to discuss: • Cleanup standards • Cleanup options (including monitored natural attenuation (MNA), risk assessment, pilot testing, site controls) • Confirmation sampling • Cost effectiveness • Public notification requirements • Technical specifications requirements and construction requirements • Project timeframes and milestones • Operation and maintenance requirements • Reporting requirements UTAH DEPARTMENT of ENVIRONMENTAL QUALITY ENVIRONMENTAL RESPONSE & REMEDIATION NON-PST CAP Guide MAY 2017 Page 2 2. Corrective Action Plan Components A CAP should be submitted that details the requirements discussed in the meeting. The items bulleted in the CAP Meeting Section should be considered when developing the CAP, if a CAP meeting was not conducted. The remainder of this guide contains the information necessary for putting together the CAP. Use of this guide will ensure the CAP is complete and will minimize the DERR's review time. The following components should be included in the CAP: a) Introduction The CAP introduction should include a discussion of the following topics: • The facility identification number, release site number and location or address of the release site • The purpose and objectives of the corrective action • A brief description of the work completed at the site • Project timeframes and milestones b) Corrective Action Comparison and Selection This section should summarize the cleanup options being considered. The feasibility and cost-effectiveness of the selected technology should be discussed in detail based on soil type, depth to groundwater, extent of contamination, contaminant characteristics, hydraulic conductivity, and current and future land use. c) Corrective Action Design and Construction Details This section should contain design and construction details of the selected corrective action technology and may include the following: • Appropriately scaled drawings of system components, showing locations and details • Design criteria and supporting manufactures specifications • Calculations for sizing equipment • Operations and maintenance specifications and schedule • Safety and security measures • A sampling and monitoring schedule • An emergency response plan • Estimated efficiency of the system and the expected duration • Any other technical specifications • Soil aeration or disposal details (refer to Guidelines for Disposition and Treatment of Petroleum Contaminated Soils from Underground Storage Tank Sites UTAH DEPARTMENT of ENVIRONMENTAL QUALITY ENVIRONMENTAL RESPONSE & REMEDIATION NON-PST CAP Guide MAY 2017 Page 3 d) Permitting Requirements Various regulatory agencies may need to be notified during the course of remediating petroleum releases. Refer to Permitting and Other Approvals information in Attachment C for more information. e) Public Notification Prior to implementing any corrective action, the potentially affected public must be notified of the corrective action. Public notification is required by a means designed to reach the segment of the public who may be directly affected by the release or the corrective action process. These methods may include personal contact or notice, notice in newspapers or flyers, or other appropriate methods. Planned public notice distribution details should be included. If significant concerns are raised by impacted individuals and/or businesses, a public meeting may be necessary. Attachment B provides a template for public notice, which should be submitted with the CAP. The public notice should include all requirements outlined in the Public Notice Template. f) Sampling Plan and Monitoring Schedule This section should include the sampling plan and/or a monitoring and maintenance schedule during the cleanup process. Remediation progress reports may be necessary during cleanup activities and should be included. This section and plan should include the sampling methodology and laboratory analytical methods. The type, location/depth, frequency and rationale for all samples should also be included. 3. Corrective Action Plan Approval The LUST PM reviews the CAP for completeness. If the CAP does not meet the specified requirements, the DERR issues a ‘Corrective Action Plan Comments’ letter detailing the deficiencies. Once the CAP addresses all applicable items, the DERR issues a ‘Notice of Approval to Proceed with the Public Notification Process.’ The RP or consultant then proceeds with the public notification process as outlined in the approval letter. UTAH DEPARTMENT of ENVIRONMENTAL QUALITY ENVIRONMENTAL RESPONSE & REMEDIATION NON-PST CAP Guide MAY 2017 Page 4 Verification of the public notification must be provided to the LUST PM. This verification may consist of newspaper documentation, certified mail receipts, or a list of the households and businesses which are potentially affected and who have been notified. If significant concerns are raised by impacted individuals and/or businesses, a public meeting may be necessary. After the public notification process is complete, the DERR issues a ‘Corrective Action Plan Approval’ Letter. Implementation should be initiated as outlined in the CAP approval letter. 4. Corrective Action Reporting After the CAP has been implemented, a corrective action report must be submitted that documents the work completed. A final report, including confirmation sampling results, will be required after the corrective action is complete and the site is ready for close-out. This report verifies the effectiveness of the corrective action and documents that cleanup levels have been achieved. Depending on the corrective action selected, the report may include the following: • Summary of field activities • As-built drawings and construction details • Tabulated analytical data and laboratory reports • Soil boring logs and/or well construction details • Scaled maps showing all environmental sample locations and receptors • Groundwater gradient maps • Soil and groundwater iso-concentration maps • Other agency permits or approval letters • Photographs and other supporting information • Volumes of soil and groundwater removed and/or treated • Estimated residual contamination volumes • Waste disposal methods, location, and documentation (waste manifests) • Information regarding the results/effectiveness of the corrective action • Proposed modifications to the approved CAP • Plans for future work • Ongoing reporting schedule and details UTAH DEPARTMENT of ENVIRONMENTAL QUALITY ENVIRONMENTAL RESPONSE & REMEDIATION NON-PST CAP Guide MAY 2017 Page 5 5.
