SUBJECT: Negotiation Summary – BIL22 Task Assignment (TA) Change Order #4 – TA BIL02AC4 Broward County School Board Property – Site ID # ERIC_18360 Supplemental Site Assessment Activities

This Task Assignment Change Order (TACO) is for the reduction of costs in relation to Terracon using lower tier and/or local staff for Subtasks 7 and 8, and associated Project Management (Subtask 1) reductions. Specific changes are detailed below:

Subtask 1: Project Management The change in costs associated with this subtask is calculated automatically at 13% of the change in the direct labor costs of the remaining subtasks. This resulted in a cost actual decrease of ($360.16).

Subtask 7: IDW Management Changes to this subtask resulted in a cost actual decrease of ($712.66).

Subtask 8: Additional Supplemental Site Assessment Activities Changes to this subtask resulted in a cost actual decrease of ($2,305.27).

Summary The Department’s BIL Contract Manager and Terracon’s Contract Manager have both agreed to the above changes. All changes noted above represent a total overall cost decrease of ($3,378.09), as shown in the Delta and Cost Actual CEF/LOE. The changes were noted in the TACO Request received from Terracon on September 10, 2024. The final cost associated with this TA decreased from $154,128.37 to $150,750.28.

Documentation of the changes is included in the attached TACO Request, the Delta LOE spreadsheet and the Cost Actual LOE spreadsheet, and the TACO form for BIL02AC4 prepared by the Department.

Proposal for Supplemental Site Assessment and Preparation of Report SBOBC Plantation Site Plantation, FL September 10, 2024 Terracon Project No. 34237223

1.0 PROJECT INFORMATION

The School Board of Broward County - Plantation site is an approximate 13.06-acre parcel of land located at the SE Corner of south Hiatus Rd and west Broward Blvd, Plantation, Broward County, Florida (hereinafter, referred to as the site). The site is comprised of two land parcels identified as Broward County Property Appraiser’s office (BCPAO) parcel identification numbers 5041-07-15-0020 (11.87 acres southern portion) and 5041-10-70-0140, (1.19-acre northern portion) The site is located in Section 7, Township 50 South, and Range 41 East. The approximate latitude/longitude coordinates of the site are N: 26° 7' 10.68" / W: -80° 17' 43.61".

The site is currently vacant land and is present as a cleared maintained grassed field with 2-to-3-foot undulations observed in certain areas.

Historically, the site was part of a larger agricultural area that was utilized to cultivate row crops from approximately 1968 to 1999. The site also contained a maintenance/equipment storage/staging area in its northwestern portion and a drainage canal previously transected the entire northern parcel along its frontage with west Broward Blvd.

The review of historical reports and analytical data indicate the presence of arsenic and toxaphene at concentrations in soil above the SCTLs and arsenic concentrations in groundwater above the GCTL.

The extents of soil and groundwater impacts have yet to be satisfactorily delineated. The identified areas are believed to be related to the former row crop agricultural operations and an associated maintenance structure formerly located in the northwest portion of the site. This proposal is based on the EPA and FDEP signed and approved QAPP for the project site received September 13, 2023.

2.0 SCOPE OF SERVICES

Based on prior discussions via phone and email, the proposed scope of services consists of five subtasks involving Project Management, background soil sampling, soil boring and monitoring well installation, groundwater sampling, IDW management and producing a Supplemental Site Assessment Report:

Removed

September 10, 2024 Terracon Project No. 34237223

Subtask Description

Subtask 3. Soil Boring Installation, Monitoring Well Installation, Groundwater Sampling and Analysis

This is the work completed, invoiced

Install (11) soil borings to a depth of 4 feet bls and collect soil samples at 0-0.5-, 0.5-2- and 2–4-foot depth bgs. Analyze for Organochlorine pesticides (OCP) by EPA Method 8081 and EPA Method 6020 for arsenic.

Supervise installation of Seven shallow monitoring wells to 13 ft bgs constructed of 1-inch dia. PVC riser with 10 ft of 0.006-inch slotted screen and 30/65 grade sand filter pack. Additionally, install one deeper surficial zone monitoring well to 21 ft bgs constructed of 1-inch dia. PVC riser with 5 ft of 0.006-inch slotted screen with a 30/65 grade sand filter pack. Four of the nine monitoring well locations will have soil analytical samples collected at three depth intervals (0-0.5, 0.5-2 and 2-4), for OCP by EPA method 8081 and arsenic by EPA method 6020.

Redevelop four existing stickup temporary wells and complete with a 2’x2’ pad and a 4”x5’ aluminum stickup.

Collect 11 groundwater samples for laboratory analysis by EPA method 6020 for arsenic and EPA Method 8081 for OCP. The analysis will be performed using a NELAC approved laboratory.

Subtask 4. IDW Management This scope of work completed Coordinate the collection and disposal of up to 4 drums investigation derived waste (IDW)

Subtask 5. Supplemental Site Assessment Report

Prepare a Supplemental Site Assessment Report with site history, methodology, conclusions, recommendations, tables, sample locations and concentration exhibits, sealed by a Professional Geologist. Extra time is allotted to compile the historical data into figures for inclusion in the SSA. Amended Task 5 to add additional data from proposed Subtask 6 and 7, and to include time for progress meetings with the School Board and their Legal Counsel, and with Broward County.

September 10, 2024 Terracon Project No. 34237223

Subtask Description

Subtask 6. Soil Boring Installation, Monitoring Well Installation, Groundwater Sampling and Analysis

This is the work completed, Invoiced.

Initially Resample newly installed and existing monitoring wells DMW-1, TMW-1 and GP-2 to confirm November sampling results. In addition, gauge all site monitoring wells to generate an updated groundwater flow interpretation.

Install (19) soil borings to a depth of 4 feet bls and collect soil samples at 0-0.5-, 0.5-2- and 2–4-foot depth bgs. Install 3 deeper soil borings at previous soil borings and new shallow well locations and analyze 4-6, 6-8 and 8-10 foot bgs(to account for topography undulations) depth intervals for Organochlorine pesticides (OCP) by EPA Method 8081 and EPA Method 6020 for arsenic.

Supervise installation of seven shallow monitoring wells to 13 ft bgs constructed of 1-inch dia. PVC riser with 10 ft of 0.006-inch slotted screen and 30/65 grade sand filter pack. Additionally, install four deeper surficial zone monitoring well to 21 ft bgs constructed of 1-inch dia. PVC riser with 5 ft of 0.006-inch slotted screen with a 30/65 grade sand filter pack. Three of eight shallow monitoring well locations will have soil analytical samples collected at three depth intervals 4-6, 6-8 and 8-10 ft bgs (to account for topography undulations), laboratory analysis for OCP by EPA method 8081 and arsenic by EPA method 6020.

Complete wells with a 2’x2’ pad and a 4”x5’ aluminum stickup.

Supervise a Specific Purpose survey and onsite topographic study to support the site assessment.

The proposed deeper vertical extent well could not be installed due to a hard formation and limited penetration of the compact drilling equipment
