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 standards1.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 requirements2. Corrective Action PlanComponents 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:Introduction The CAPintroduction should include a discussion of the following topics:The facility identification number, release site number and location or address of the release siteThe purpose and objectives of the corrective actionA brief description of the work completed at the site Project timeframes and milestonesCorrective 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.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 detailsDesign criteria and supporting manufactures specificationsCalculationsfor sizing equipmentOperations and maintenance specifications and scheduleSafety and security measuresA sampling and monitoring scheduleAn emergency response planEstimated efficiency of the system and the expected durationAny other technical specificationsSoil aeration or disposal details (refer toGuidelines for Disposition and Treatment of Petroleum Contaminated Soils from Underground Storage Tank SitesPermitting 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. 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. 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 necessaryduring 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. 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 closeout. 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 5.
