Department of Environmental Protection Waste Cleanup Program ATTN: Ms. Ginger Shirah MS #4535 Bob Martinez Center 2600 Blair Stone Road Tallahassee, Florida 32399-2400

Reference: Florida Department of Environmental Protection (DEP) Waste Cleanup Programs Consolidated Contract HW560

Subject: Updated Cost Proposal – Site Inspection at Pronto Circuit Technologies, Pompano Beach, Broward County, Florida

Dear Ms. Shirah:

Tetra Tech Inc., (Tetra Tech) is pleased to submit to the Florida Department of Environmental Protection (FDEP) this cost proposal to conduct the Site Inspection (SI) at the Former Pronto Circuit Technologies Site located at 3000-5 NW 25th Avenue, in Pompano Beach, Broward County, Florida. Services provided in this proposal will be completed as four subtasks including: Subtask 1, Project Management; Subtask 2, Work Plan and Health and Safety Plan (HASP); Subtask 3, Fieldwork including Monitoring Well Installation and Groundwater Sampling; and Subtask 4, Report. These subtasks will include the following activities:

Subtask 1 - Project Management: Project Management includes managing the project scope, schedule, and budget; and procurement of subcontractors. The level of effort is based on the HW560 Contract requirements and assumes 8 hours for Task 1.

Subtask 2 - Work Plan & HASP: This task includes completion of a Work Plan and Health and Safety Plan for the sampling event and to coordinate utility location activities. The level of effort assumes 1 hour for a Scientist V (Gerry Walker [GW]), 4 hours for a Scientist V (Rick Hicks [RH]), 16 hours for an Engineer II (Misty Quandt [MQ]), and 2 hours for figure preparation (James Madden

[JM]).

Subtask 3 – Well Installation and Groundwater Sampling: This subtask includes monitoring well installation, groundwater sampling, and other field activities conducted by a Scientist IV (Shawn Ouellette [SO]) and a Scientist II (Jessica Endicott [JE]). The field activities and level of effort summary are described below, and the level of effort, subcontractor, equipment, travel, and supplies needed for this subtask are described in the cost estimate worksheets. Proposed monitoring well locations are shown in Figure 1.

Monitoring well installation and abandonment. Based on groundwater flow data from the Preliminary Assessment (PA), local groundwater flow is assumed to be to the southeast.

Three temporary monitoring wells will be installed at the site to evaluate upgradient (from

Tel 850.385.9899 Fax 850.385.9860 www.tetratech.com the west) and site-affected groundwater quality to the south and east of the former business location. Prior to the monitoring well intrusive activities, Tetra Tech will have the boring locations surveyed for buried utilities by a utility locator service (Site Lines, see attached quote). The monitoring wells will be installed as small diameter (micro) PVC wells installed by a direct-push drilling contractor (selected contractor is Preferred Drilling; see attached quotes). Each well will be completed to an approximate depth of 10 to 12 feet below land surface (bls). Actual well depths and screen placement will be determined based on lithology and depth to groundwater encountered in a continuous core hole advanced at each well location. Screens will be placed so that the upper 1/3 of the screen is above the water table, if allowable by the water table. The estimated depth to groundwater reported in the PA was less than 1-foot bls. Each well will be constructed of 1-inch-diameter PVC casing with a 10-foot-long pre-packed well screen, with a fine sand seal above the well screen. Clean bagged sand will be used to fill the annular space above the seal. As soon as the wells are installed, they will be developed by pumping and then purged for sampling.

After Tetra Tech completes sampling and a top-of-casing/water level survey, the wells will be abandoned in place by grouting using the tremie method, with the well casings pulled or cut off bls, and the surface restored to the pre-existing condition. By using this method for well installation, there will be no drill cuttings to collect as investigation-derived waste (IDW). Development and purge water will be allowed to infiltrate into the soil at the well sites. Based on time estimates from the drilling contractors, it is estimated that the soil boring, monitoring well installation, and well development work will be completed in one day. Abandonment of the wells will occur after the groundwater samples are collected, the wells are surveyed and the depths to groundwater are measured. Tetra Tech will request a change order to reduce drilling cost if actual invoiced amount is different than the amount included in this cost proposal.

Groundwater sampling. The three temporary wells will be sampled during the site inspection shortly after they have been developed, with no specific waiting period between development and sampling. Each well will be purged with a peristaltic pump and Teflon tubing using low-flow sampling procedures and samples will be collected for laboratory analysis of 22 Target Analyte List of metals per Method 6010D plus Mercury (Hg) per Method 9470A; Target Compound List Volatile Organic Compounds (VOCs, per Method 8260D); and Cyanide (Method 9012B). In addition, Quality Control (QC) samples are included in the cost proposal for your consideration. These include one field duplicate and one equipment rinsate blank (for all analytical methods identified above), and one trip blank (for VOCs only). FDEP guidance (FC1000 in https://floridadep.gov/dear/quality-assurance/content/dep-sops) defers to programs on selection and number of field duplicate samples needed for a given project, although equipment and trip blanks are required. Temperature blanks will be carried in all coolers. A CLP-Like Level IV analytical data package will be provided by the subcontracted analytical services laboratory (TestAmerica) for their deliverable. There is no additional cost to FDEP for the Level IV deliverable.

Other field activities. A hand-held global positioning system (GPS) will be used by Tetra Tech staff to survey latitude and longitude coordinates of the sampling stations. In addition, all monitoring well tops of casings will be surveyed by Tetra Tech staff to a common onsite datum and depth-to-groundwater measurements will be taken during the study to document groundwater flow direction.

The field personnel will mobilize from Tetra Tech’s Stuart, Florida office, arriving on site to conduct a reconnaissance and locate buried utilities the day before other field work begins.

Tel 850.385.9899 Fax 850.385.9860 www.tetratech.com

The proposed hours for this subtask include 2 hours for a Scientist V (RH, for coordination and deliverable review), 20 hours for the Scientist IV (SO) and 18 hours for a Scientist II (JE) based in Stuart Florida (for mobilization and field work) and 2 hours for the Engineer II (MQ, for the field task deliverable preparation). The staff in Tetra Tech’s Stuart office are dedicated to work on FDEP’s Consolidated Contract and have extensive experience in CERCLA and Brownfields assessment work. Their office is also located within 1.5 hour drive of the site.

The field work is anticipated to be completed in a two-day period, which includes mobilization and a site walkover to establish the sampling stations and locate utilities on the first day; and monitoring well installation, sampling and demobilization on the second day.

Subtask 4 - Report:

The level of effort assumes 2 hours for a Scientist V (GW), 4 hours for a Scientist V (RH), 32 hours for an Engineer II (MQ), and 4 hours for figure preparation (JM). Report tasks include preparation of draft and final reports documenting the field activities, site conditions, and results of the sampling effort. The report will adhere to the recently developed template for streamlined CERCLA Site Inspection Reports and will include information on site background and observations and findings of the SI. The document will include a site location map, sampling location map, a map showing direction of groundwater flow, and maps showing contaminant concentrations in groundwater. The report will also contain tables of summary information for the groundwater samples collected, monitoring well construction, depths to and relative elevations of groundwater, summary data from the laboratory analyses, and comparisons of analytical results to background concentrations; Florida Groundwater Cleanup Target Levels; and U.S.

Environmental Protection Agency (USEPA) Maximum Contaminant Levels. Appendices will also be provided that include the laboratory analytical data sheets, copies of field notes, groundwater sampling forms, field equipment calibration sheets, chain of custody forms, and site photographs.

Tetra Tech’s cost proposal is based on the following assumptions:

Site access to enter the property or adjacent locations and complete the indicated fieldwork will be obtained by FDEP. If Tetra Tech needs to obtain right of way access and permits for well installation on public rights of way, there may be additional cost.

The samples will be analyzed by TestAmerica using rates in Contract HW560. There is no additional cost for a Level IV deliverable package. Tetra Tech will coordinate the laboratory’s reservation and analysis.

Electronic copies of all reports and field information (field notes, well installation logs, groundwater sampling forms, etc.) and laboratory results will be submitted to FDEP. Paper copies of reports and project deliverables will not be submitted.

The field activities will be scheduled once the project work plan is approved by FDEP and

USEPA.

The selected subcontractors will provide the well installation and utility location services.

IDW will not be containerized.

Tetra Tech is prepared to begin work on this project following receipt of a signed FDEP task order.

A signed task order will reflect the approval of this proposal and authorize use of associated funding

Tel 850.385.9899 Fax 850.385.9860 www.tetratech.com required to commence project activities. The total fixed price cost to complete the activities described above is $19,749.66.

Please find a cost summary attached that provides details concerning this cost proposal and competitive bids obtained for drilling and utility locate services. Tetra Tech anticipates completion of this project on a fixed price basis and will invoice costs incurred at 100% completion based on approval of deliverables and in accordance with deliverable due dates.

COST QUOTE FOR

DIRECT PUSH WELL INSTALLATION SUPPORT

FDEP CERCLA Site Screening Site

Former Pronto Circuit Technologies

3000-5 NW 25th Avenue

Pompano Beach, Broward County, FL

Tetra Tech is requesting a cost quote for providing direct push services for an FDEP site in Pompano

Beach, Broward County, FL. This is a private property in an industrial setting with all probe sites on private property or public rights of way with permits in place. Level D health and safety protocol. Tetra

Tech representative will be on site to coordinate. All site access will be obtained, and all utilities will be located via One Call by Tetra Tech in advance of probing. All probe sites are accessible to a track-mounted direct push rig. Asphalt may need to be penetrated. All work is shallow, with water table expected to be 1 foot or less below land surface.

SCOPE OF WORK

1- Post hole or auger each hole for well installation to confirm utility clearance.

2- Decontaminate casing and rods before and between probe locations using liquinox and clean potable quality water. A source for decon water may not be available on site.

3- Advance 3 soil core holes, collecting soil samples continuously from land surfact to 10 feet below land surface for description by Tetra Tech rep. Put cores back into hole.

4- Install 3 temporary wells using 1-inch micro wells (or equivalent) and 10-foot-long prepacked well screens. Each well will be an estimated 12 feet total depth. Use clean sand to fill annular space around and above screens and top off with fine sealer sand. Add no water. Cut off casings at just above surface and install well caps. No well protectors or vaults needed.

5- Investigation derived waste does not need to be drummed. Put soil cores back into hole.

Decontamination site will be on porous ground and rinsate can be allowed to soak into the ground. Remove all trash generated from your activities.

6- Wells will be developed/purged and sampled by Tetra Tech shortly after they are installed.

Abandon the wells by tremie grouting in accordance with WMD/Broward County requirements after they are sampled. Crew will need to wait until wells are purged and sampled before abandoning them.

7- Obtain all permits for temporary well construction/abandonment as appropriate.

8- Include mobilization and per diem costs as appropriate.

9- Drill crew members must have current health and safety training and medical monitoring.

10- Anticipated schedule for doing the work is mid-January, 2021.

SITE LINES LLC PROPOSAL

SITE LOCATION

Pronto Circuits Site – 3000 NW 25th Avenue, Pompano Beach, FL

PROPOSED SCOPE OF WORK

Site Lines (“Company”) will use Ground Penetrating Radar (GPR) and conventional electromagnetic (EM) pipe and cable locators to determine the location of underground utilities at the site identified by Tetra Tech (“Client”). Of specific concern is the utilities within the area of approximately 3 proposed monitoring well locations. A map of the locations was provided and is attached to the back of this document.

RESULTS OF THE INVESTIGATION

The estimated depth and location of utilities identified during the investigation will be marked on the ground surface using spray paint or other method to be agreed upon by the parties. Designated utilities will also be documented on a field sketch.

The American Public Works Association Uniform Color Codes for the marking of underground utilities will be used.

PROJECT FEE

The fee to complete the project as described within this proposal is: Six Hundred Dollars [$600.00].

Client shall pay Company in full within thirty (30) days of the invoice date, unless the parties have agreed to another payment arrangement in writing. If during the investigation, Company determines that the goals of the project cannot be achieved with the resources available to Company, Company will notify Client as soon as reasonably possible. Under such circumstances, Company will charge Client only for time expended and materials used to date.

CLIENT REQUIREMENTS

Client is responsible for all site access, maintenance of traffic (MOT), site clearing and/or any other logistical considerations necessary to conduct the utility locate.

Client will also provide all pertinent maps of the project site, including those that show the boundaries of the utility locate, pertinent landmarks, and known utilities (if available). Company is not a substitute for Chapter 556, Florida Statutes.

Accordingly, Client is responsible for calling Sunshine State One Call of Florida

(811) before undertaking any invasive activities, whether through Company, any other entity, or on its own.

DESCRIPTION OF COMPANY INVESTIGATION AND LIMITATIONS

A GSSI SIR-4000 GPR system will be used with a 900, 400, or 270 megahertz antenna configuration depending on site conditions and desired targets. The GPR will assist in locating nonmetallic and metallic utilities. Physical surface conditions, subsurface conditions and technical limitations effect the ability of GPR to resolve targeted utilities and/or subsurface structures. Depth and/or diameter of the utility, soil type, moisture/ionic content of the soil, and electrical properties of the soil compared to that of the utility can prevent the GPR from identifying utilities at the site. The diameter of a utility cannot be determined by GPR data. Estimated depths of utilities are directly affected by soil conditions and the material of the utility. A margin of error of +/- 20-25% in depth should be expected when performing invasive activities.

An RD 8000 will be used for the EM survey. Electromagnetic induction which transmits a signal directly into the desired target and passive power detection which locates naturally occurring magnetic fields in energized lines will be identified by detecting and following the signals with a receiver. The EM survey will assist in finding only metallic utilities. The magnetic field and/or induced signal should emanate from the target in a circular geometry. When this occurs, the receiver will receive its peak signal directly above the target. However, when metallic utilities are running near each other, or there is environmental interference from fences, cars or overhead power lines, the signal can become distorted and the peak no longer can be directly over the utility. Care must be taken when doing any invasive work around the utilities. A margin of error of +/- 20-25% in depth should be expected when performing invasive activities. Company’s personnel are highly experienced and certified operators of GPR and EM pipe and cable locators.

Due to the limitations described above, when Client is working around indicated utilities, a minimum of two (2)-feet clearance from either side of the marked utility will be maintained. For absolute confirmation, Client is responsible for exposing any indicated underground utility.

Company will conduct utility investigations in accordance with the level of care and generally accepted professional practices as ordinarily exercised by members of the same profession practicing in the same locality under similar conditions.

REPRESENTATIONS AND WARRANTIES

Neither Company nor its employees or agents are licensed surveyors under Florida law, nor do they represent themselves as such. Accordingly, the work Company is to perform is not a substitute for work typically completed by a licensed surveyor.

Company specifically and expressly disclaims any liability for any type of property damage or personal injury, including but not limited to death, arising from client’s failure to determine that the services of a licensed surveyor are necessary or to retain a licensed surveyor to perform necessary services.

Limitations in technology, complexity of the physical characteristics of the subsurface conditions, and circumstances beyond Company’s control may limit the performance of Company’s utility investigation. For these reasons, Company expresses no guarantee that all utilities and underground structures will be identified and located during this project.

Company is responsible only for locating underground utilities, the presence of which is both known and indicated on site maps to be provided by Client to Company before Company performs the utility locate. Company will use its best efforts to locate both known and unknown utilities within the project boundaries.
