Task Assignment HW687 CSS03B Terracon Proposal No. PEQ257126

Dear Ms. Field:

Terracon Consultants, Inc. (Terracon) appreciates the opportunity to submit this proposal to the Florida Department of Environmental Program (FDEP) CERCLA Site Screening Section to prepare a perform site investigation (SI) activities and prepare a Site Inspection Report (SIR) pursuant to the approved Field Sampling Plan for the Former Cal-Spray Chemica Co. (ERIC_18464) facility located at 1715 Silver Star Road, Orlando, Orange County, Florida.

Scope of Services

Review the approved Field Sampling Plan (FSP) and Health and Safety Plan

Field preparation and oversite of geophysical investigation.

Mobilize to site and advance 8 soil borings with soil sampling and the installation of six shallow temporary monitoring wells to a depth of 12 feet below ground surface (bgs).

Collect soil samples 0-1, and 1-2 feet bgs from each soil boring and submit for laboratory analysis for volatile organic compounds (VOCs), organochlorine pesticides (OCPs), insecticides/herbicides and 8-RCRA metals

Perform groundwater sampling at the six temporary monitoring wells and the three existing monitoring wells for laboratory analysis of VOCs, OCPs, insecticide/herbicide and 8-RCRA metals, survey elevation of top of casings, and document water levels from the six temporary monitoring wells: MW001, MW002, MW003, MW004, MW005 and MW006 and the three permanent monitoring wells (MW012, MW011 and MW016). The temporary monitoring wells will be abandoned after groundwater activities are completed.

Proposal for Site Investigation and Reporting Former Cal-Spray Chemical Co., ERIC_18464 Orlando, FL March 20, 2025 Terracon Proposal No. PEQ257126

The investigative derived waste (soil and groundwater) will be containerized in 55-gallon drums and sampled for characterization once sampling is complete.

Review data and prepare the Site Inspection Report (SIR).

See attached LOE for details

Schedule

Deliverable of field notes, lithological logs, well installation logs, photolog, and chain-of-custody documentation within 5 business day of completion of field work.

Deliverable of SIR within 20 business days following receipt of laboratory results.

Compensation See attached CEF for details.

SCOPE OF SERVICES

Subtask 1: Project Management This scope is provided for in the template worksheets for project management.

Subtask 2: Site Investigation Terracon will coordinate a pre-drilling meeting with owner, drillers, geophysical survey subcontractor, and the FDEP.

Oversight of geophysical survey subcontractor Geoview for private utility locates.

Collection of soil samples at eight locations with sampling intervals of 0 to 1 feet below ground surface (bgs) and 1 to 2 feet bgs. Samples are to be submitted to the FDEP Laboratory for analysis for volatile organic compounds (VOCs) by EPA Method 8260, organochlorine pesticides (OCPs) by EPA Method 8081, insecticides/herbicides by EPA Method 8321B and 8- RCRA metals by EPA Method 6020/7471.

Supervise the installation of six temporary shallow monitoring wells at the soil boring locations; the temporary wells are constructed to 14 feet bgs, with 10 feet of 0.006-slotted prepacked screen and 30/65 silica sand.

Drilling services are provided by JAEE using direct push technology and hollow stem auger installation.

Terracon will create an arbitrary datum to survey the temporary monitoring well and the permanent monitoring well top of casings to provide groundwater elevation data and to assess groundwater flow direction.

Collection of depth to groundwater at the six temporary monitoring wells and 3 permanent monitoring wells to provide groundwater elevation data and evaluate shallow groundwater flow direction.

Collection of 6 groundwater samples from the temporary monitoring wells and an additional 3 groundwater samples from the three permanent monitoring wells for VOCs by EPA Method 8260, OCPs by EPA Method 8081, insecticides/herbicides by EPA Method 8321B and 8-RCRA metals by EPA Method 6020/7471. Groundwater sampling will occur a minimum of 24 hours after the temporary monitoring wells installation. The groundwater samples will be submitted to the FDEP Laboratory for analysis.

IDW generated from drilling and groundwater sampling activities will be collected and staged onsite in FDOT approved 55-gallond drums. Once field sampling is complete, samples will be collected from the IDW drums for waste characterization.

Proposal for Site Investigation and Reporting Former Cal-Spray Chemical Co., ERIC_18464 Orlando, FL March 20, 2025 Terracon Proposal No. PEQ257126

Once the IDW waste characterization laboratory results are received, and assessed whether hazardous or non-hazardous, then Terracon will solicit bids for IDW disposal.

Subtask 4: Prepare Site Inspection Report (SIR) Preparation of a SIR to include an evaluation of soil and groundwater data, establish site-specific background screening concentrations for soil and groundwater under investigation and compare environmental sample data results to USEPA and FDEP Cleanup Target Levels (CTLs).

SCHEDULE

Deliverable of field notes, lithological logs, well installation logs, groundwater sampling logs, photolog, and chain-of-custody documentation within 5 business days of completion of field work.

Deliverable of SIR within 20 business days following receipt of laboratory results.

CLOSING REMARKS

Terracon services will be conducted in accordance with the terms and conditions, contained within DEP Waste Cleanup Program (WCP) Contract No. HW687, executed January 5, 2022. It is understood that a Task Assignment will be issued to authorize us to perform this work.

We appreciate the opportunity to provide this proposal and look forward to working with you on this project. If you should have any questions or comments regarding this proposal, please contact either of the undersigned at (904) 470-2233 and (904) 479-7415.

Low Bid: Action Environmental

General Information: Terracon is soliciting quotes from three (3) Florida licensed well contractors, on behalf of the FDEP , for the following scope of services. The driller will be responsible for all necessary permits, public utility locates, equipment and personnel to complete this scope of work. The driller should be aware that changes in scope may occur once the work has begun.

Scope of Work: Installation of six (6) soil borings/TMW advanced to 14 feet bgs using DPT installation. Soil samples collected from two intervals (0–1 foot bgs and 1-2 feet bgs).

TMW will be installed at each location with 10 feet of 0.006-inch slotted, prepacked screen and 30/65 silica sand.

Decontamination: All downhole tools will be decontaminated prior to and between each sample interval location (i.e. every foot during hand auger advancement and every five feet during macrocore advancement). Specific decontamination procedures include alconox scrub and steam wash applies for all drilling equipment and downhole tools (e.g., tremie pipe, hoses). Decontamination fluids and solids will be containerized separately. Offeror’s equipment shall arrive clean and free of soil or dirt from its previous work location.

Investigation Derived Waste (IDW) and Trash: Soil cuttings, decontamination water and solids, and development water (IDW) generated during well installation will be drummed. The Driller will supply a sufficient number of FDOT-approved 55-gallon steel drums to contain all IDW generated during site activities.

The Offeror will be required to consolidate the IDW drums into one central location.

Drilling Conditions: The site is not an active facility. Some vagrant activity in the area. It should be assumed that potable water and electricity are not available.

The depth to water is estimated at 6.0 feet bgs.

Health and Safety: Work is expected to be performed in Level D personal protective equipment. The primary contaminants of concern at the site are organochlorine pesticides. Proper safety procedures to minimize contact with contaminated site media is required. Site personnel are required to be 40-hour OSHA trained.

Line items will be invoiced based upon actual quantities/depths completed in the field.
