Task Assignment Summary

HW684 TA DC012C

Operations & Maintenance (O&M)

GHD Services, Inc. (GHD) will conduct 12 months of O&M. Specific subtasks are detailed below:

Subtask 1: Project Management Project Management is calculated at 13% of the direct labor.

Subtask 2: O&M (April 2023 through September 2023) During monthly site visits, the SVE system operations will be verified. The system operational conditions will be recorded. These conditions include the current status of each SVE well (open/closed), vacuum readings at wellheads, flow readings (total and well), hour meter readings, and water accumulation. During monthly site visits, the SVE operations will be modified (as directed by the Engineer) in order to optimize mass recovery. Verification of radius of influence may also be conducted. During quarterly site visits, field screening measurements will be recorded for each SVE well. Sampling will be conducted at effluent ports for laboratory analysis. All vapor samples will be analyzed for the presence of volatile organics by Method TO-15 and air phase hydrocarbons by MADEP APH Method. After six months of operation and receipt of analytical data, an email summary will be prepared including recommendations for additional operations and/or modifications. The email summary will include update remedial action tables and any additional groundwater sampling information.

Subtask 3: Utilities (April 2023 through September 2023) Subtask 3 includes six (6) months of utility (electrical) service. The utility service was obtained through TECO and GHD will submit invoices for reimbursement.

Subtask 4: O&M (October 2023 through March 2024) During monthly site visits, the SVE system operations will be verified. The system operational conditions will be recorded. These conditions include the current status of each SVE well (open/closed), vacuum readings at wellheads, flow readings (total and well), hour meter readings, and water accumulation. During monthly site visits, the SVE operations will be modified (as directed by the Engineer) in order to optimize mass recovery. Verification of radius of influence may also be conducted. During quarterly site visits, field screening measurements will be recorded for each SVE well. Sampling will be conducted at effluent ports for laboratory analysis. All vapor samples will be analyzed for the presence of volatile organics by Method TO-15 and air phase hydrocarbons by MADEP APH Method. After the 12th month of operation and receipt of analytical data, a Remedial Action Status Report (RASR) will be prepared including recommendations for additional operations and/or modifications. The RASR will include updated remedial action summary tables and will also summarize any additional groundwater sampling results obtained as part of the RAP implementation.

Subtask 3: Utilities (October 2023 through March 2024) Subtask 3 includes six (6) months of utility (electrical) service. The utility service was obtained through TECO and GHD will submit invoices for reimbursement.

GHD and the FDEP confirmed on April 10, 2023, that an Access Agreement with the current real property owner of the aforementioned site has been executed.

Documentation of the costs is included in the attached CEF, Level-of-Effort sheets, and the GHD proposal submitted on April 3, 2023. Specific. The final deliverable due date is May 17, 2024, and the completion date for the task assignment is August 18, 2024.

The final cost total for Task Assignment DC012C is $30,955.52.

COST PROPOSAL FOR TASK DC012C

<Nu Way Cleaners, Inc./FDEP #ERIC_4701>

< Operations & Maintenance (Twelve Months)> (April 2023 through March 2024)

1. INTRODUCTION: <DISCUSS SCOPE OF WORK, DATES >

GHD submitted a Site Assessment Report/Interim Source Removal Plan (SAR/ISRP) for the Nu-Way Cleaners, Inc. site located in Plant City, Hillsborough County, in July 2015. The SAR/ISRP was approved and the soil vapor extraction (SVE) system was installed in April 2016. Startup of the SVE system occurred on May 20, 2016. Although the system has likely removed the majority of available mass in the vadose zone, additional operations are recommended as part of the recently approved RAP in order to mitigate and potential vapors generated during enhanced groundwater bioremediation.

Task DC012C includes twelve (12) additional months of operation of the SVE system (April 2023 through March 2024). O&M will include monthly site visits and quarterly air sampling.

During monthly O&M site visits, the remedial system operation will be verified and performance monitoring will be conducted. Performance monitoring will include determining and adjusting operating conditions to maximize mass recovery.

Subtask 1: Project Management Subtask 1 includes all tasks associated with management of six (6) months of O&M, sampling, and reporting at the Nu-Way Cleaner site.

Subtask 2: O&M (April 2023 through September 2023) During the operational period, GHD will conduct monthly Operations and Maintenance (O&M) site visits. During monthly site visits, the SVE system operations will be verified. The system operational conditions will be recorded. These conditions include the current status of each SVE well (open/closed), vacuum readings at wellheads, flow readings (total and well), hour meter readings, and water accumulation. During monthly site visits, the SVE operations will be modified (as directed by the Engineer) in order to optimize mass recovery. Verification of radius of influence may also be conducted. During quarterly site visits, field screening measurements will be recorded for each SVE well. Sampling will be conducted at effluent ports for laboratory analysis. All vapor samples will be analyzed for the presence of volatile organics by Method TO-15 and air phase hydrocarbons by MADEP APH Method.

After six months of operation and receipt of analytical data, an email summary will be prepared including recommendations for additional operations and/or modifications. The email summary will include update remedial action tables and any additional groundwater sampling information.

Subtask 3: Utilities (April 2023 through September 2023) Subtask 3 includes six (6) months of utility (electrical) service. The utility service was obtained through TECO and GHD will submit invoices for reimbursement.

Subtask 4: O&M (October 2023 through March 2024) During the operational period, GHD will conduct monthly Operations and Maintenance (O&M) site visits. During monthly site visits, the SVE system operations will be verified. The system operational conditions will be recorded. These conditions include the current status of each SVE well (open/closed), vacuum readings at wellheads, flow readings (total and well), hour meter readings, and water accumulation. During monthly site visits, the SVE operations will be modified (as directed by the Engineer) in order to optimize mass recovery. Verification of radius of influence may also be conducted. During quarterly site visits, field screening measurements will be recorded for each SVE well. Sampling will be conducted at effluent ports for laboratory analysis. All vapor samples will be analyzed for the presence of volatile organics by Method TO-15 and air phase hydrocarbons by MADEP APH Method.

After the 12th month of operation and receipt of analytical data, a Remedial Action Status Report (RASR) will be prepared including recommendations for additional operations and/or modifications. The RASR will include updated remedial action summary tables and will also summarize any additional groundwater sampling results obtained as part of the RAP implementation.
