SUBJECT: Negotiation Summary – SRP18 Grant Task Assignment (TA) Change Order #1 – TA BF01BC1 Former Biscayne Chemical – Site ID # BF139801015 Additional Groundwater Assessment

This Task Assignment Change Order (TACO) is for additional costs associated with transport and disposal of investigation derived waste (IDW) drums and for the preparation of a groundwater monitoring report. This work was conducted at the Former Biscayne Chemical site, located at 690 NW 13th Street, Miami, Miami-Dade County. The services under this task are being conducted using federal funds from the State & Tribal Response Program (SRP) cooperative agreement that is administered by the Department on behalf of the U.S. Environmental Protection Agency (EPA).

Subtask 1: Project Management The additional labor hours expended for the IDW Management and Groundwater Monitoring Report produced an increase in Project Management. This change resulted in a cost actual increase of $2,066.55.

Subtask 2: Additional Groundwater Assessment No cost changes were associated with this Subtask.

Subtask 3: IDW Management For this subtask, Geosyntec will prepare an IDW waste characterization profile, an IDW manifest, and coordinate the transport and disposal for 10 drums of purge/development water and six drums of drill cuttings, for a total of 16 drums. This change resulted in a cost increase of $2,166.74.

Subtask 4: Groundwater Monitoring Report For this subtask, Geosyntec will compile the data collected and prepare a groundwater monitoring report which will document the field activities and laboratory analytical results.

This groundwater monitoring report will include a review and interpretation of the 2022 groundwater analytical results, plume maps, water table map, and geologic/hydrogeologic data. This change resulted in a cost increase of $15,665.75.

Subject: Proposal and Level of Effort/Cost Estimate Form Additional Groundwater Assessment Former Biscayne Chemical 690 NW 13th Street Miami, Florida 33032 FDEP Brownfield Site ID# BF139801015 FDEP Task Assignment No. BF01B (TACO-1)

Dear Ms. Johnson:

We are pleased to submit this attached Cost Estimate Form and proposed Level of Effort (CEF/LOE) to conduct additional groundwater assessment activities in accordance with the approved 28 September 2022 Additional Groundwater Assessment Workplan Quality Assurance Project Plan (QAPP). The Former Biscayne Chemical Site (Site) is in a critical redevelopment stage and the purpose of this project is to conduct additional site assessment activities to help support site closure for groundwater impacts to the property being redeveloped under a BSRA into affordable housing. The purpose of the additional groundwater assessment is to provide data for vertical and horizontal delineation of CVOCs, iron, and manganese and for the background study.

This work is being conducted so that portions of the property may be redeveloped by KTLC Biscayne, LLC for the conditional closure of the property with allowance for future residential use. Work will be conducted under the State and Tribal Response Program (SRP) grant administered by FDEP. The associated scope of work consists of the following tasks.

Changes to the SOW under this task assignment change order (TACO) 1 are shown in red text.

TACO-1 adds the cost for the transportation and disposal (T&D) of 16 Investigation Derived Waste (IDW) drums and the preparation of a Groundwater Monitoring Report.

Ms. Johnson

Former Biscayne Chemical ASA Fieldwork and ISRP Work Plan Addendum

Subtask 1 – Project Management

Subtask 2 – Additional Groundwater Assessment

The scope of work for conducting the additional groundwater assessment will include the abandonment of 23 monitoring wells, installation of 16 monitoring wells, and groundwater sampling and analyses of 38 monitoring wells. Monitoring well details including depths and screen intervals are provided in tabular form in the QAPP.

The 16 monitoring wells will be installed on-Site in the approximate locations shown in Attachment 1 of the QAPP. Monitoring wells will be installed as clusters within the same boreholes, where applicable, using a rotosonic drill rig. Monitoring wells located in clusters PMW- 1, PMW-2, PMW-5, PMW-6, and PMW-7 will be installed inside an 8-inch diameter borehole.

Monitoring wells located in clusters PMW-3 and PMW-4 will installed inside a 10-inch diameter borehole. The site lithology will be documented by evaluation of soil cores from the sonic rig from land surface to the final borehole depth at each well cluster location. Each well will be constructed of 1-inch-diameter polyvinyl chloride (PVC) with a 0.006-inch slotted, PVC screen. A 30-65 grade sand filter pack will be installed from the bottom of each well screen to a height of 2 foot above the top of the screen. Annular space located vertically between filter pack materials for individual well screen intervals will be constructed with bentonite chips. Bentonite will be allowed to hydrate to its expansion volume prior to installing the next well screen and filter pack interval. Filter pack sand and bentonite will be added via tremie pipe. Remaining annular space will be grouted to surface. Cluster wells will be completed in 8” steel manholes set in 2’ x 2’ concrete pads. Shortly after each well is installed, it will be developed until the water produced is sediment free. The top-of-casing elevations on the new wells will be surveyed by a professional land surveyor (PLS) and static depth to water will be measured in each new well and each of the other wells scheduled for sampling to determine the groundwater flow direction at the time of the field investigation.

Groundwater samples will be collected from the newly installed monitoring wells after installation (at least 24 hours after installation and development) and select existing on-Site and off-Site monitoring wells. Multiple QAQC samples will also be collected. The approximate locations of existing on-Site and off-Site monitoring wells are illustrated in Attachment 2 of the QAPP. The monitoring wells will be purged using a peristaltic pump until all field parameters have stabilized within the acceptable ranges as stated in the FDEP Standard Operating Procedures (SOPs) and turbidity is below 20 Nephelometric Turbidity Units (NTU). If the turbidity goal cannot be attained, then five well volumes will be purged prior to sampling.

Groundwater samples and QA/QC samples will be analyzed for CVOCs, Manganese, and/or Iron in accordance with Table 2 of the QAPP. Development and purge water from investigation activities will be containerized as investigation derived waste (IDW) in 55-gallon steel drums and staged on-Site.

We obtained 3 drilling quotes from Cascade, Earth Tech Drilling, and Groundwater Protection.

We have attached the 3 drilling quotes with this proposal. The second lowest bid (Earth Tech Drilling) will be used and the cost has been included in the level of effort spreadsheet. The lowest bid (Groundwater Protection) will not be used because they do not have availability to meet our field schedule which is being driven by the Site redevelopment schedule. We also received 3 bids for the monitoring well survey and the low bidder was Pulice Land Surveyors. The low bidder (Pulice) will be used and the cost has been included in the level of effort spreadsheet. We received 2 bids for utility locate and the low bidder was GeoTek. We attempted but were unable to obtain a 3rd utility locate bid from Southeastern Surveying. The low bidder (GeoTek) will be used and the cost has been included in the level of effort spreadsheet.

Subtask 3 – IDW Management

Geosyntec will prepare an IDW waste characterization profile, an IDW manifest, and coordinate disposal for 10 drums of purge/development water and 6 drums of drill cuttings (16 drums total) generated during the 2022 groundwater assessment activities.

Subtask 4 – Groundwater Monitoring Report

Geosyntec will compile the data collected and prepare a groundwater monitoring report which will document the field activities and laboratory analytical results. This groundwater monitoring report will include a review and interpretation of the 2022 groundwater analytical results, plume maps, water table map, and geologic/hydrogeologic data.

Invoice and Deliverable Schedule:

TACO-1 increases the task assignment budget by $19,899.04.
