SCOPE OF WORK

Department of Technology, Management and Budget

2025 TANK AND SOIL REMOVAL ISID RFP

A. PROJECT OBJECTIVES

The Department of Great Lakes, Environment Energy (EGLE) is seeking proposals to retain services to assist with the removal of tanks and sources of contamination associated with releases from former underground storage tank (UST) systems and other contaminant sources at multiple sites across the State. The actual number of sites is unknown, but it is anticipated that there will be several sites within the geographic boundaries of each of the following ten EGLE Remediation and Redevelopment Division (RRD) District/Field offices; Upper Peninsula District, Gaylord Field Office, Cadillac District Office, Bay City District Office, Lansing District Office, Detroit District Office, Warren District Office, Kalamazoo District Office, Jackson District Office, and Grand Rapids District Office.

The Upper Peninsula District Office will be split into an eastern and western area. All counties west of Delta and Alger counties will be considered the western upper peninsula for assignments and bidding purposes.

A list of the EGLE district offices and counties within each district boundary can be found at: EGLE District Boundaries and Office Locations.

The objectives are to remove sources of contamination (e.g. contaminated soil, USTs, pipes, pump islands etc.)

from the environment and sample soil/groundwater/soil vapor to determine the effectiveness of the source removal actions.

Work will only be performed where EGLE has signed access. No work will be conducted in road rights-of-way, easements, utility corridors, etc., unless the contractor or EGLE has obtained signed access and/or any required permits. Copies of all signed access agreements and permits, if applicable, will be supplied to the contractor. If the contractor obtains access and/or permit, a copy will be supplied to EGLE.

The State currently does not anticipate that the tank removal or excavations will be implemented on operating UST systems. There may be sites that have been redeveloped into operating facilities with abandoned USTs and the State of Michigan may utilize this contract on those types of sites.

Site photographs along with the documentation will be required at each site and must include photographs before, during and after on-site work and when the site restoration is complete and will be included as part of the Construction/Removal Report.

The following describes the required elements and services at each site in more detail.

Installation of a Soil Gas Probe/Vapor Monitoring Point

1.0 SCOPE AND APPLICATION

This SOP describes the MDEQ’s procedure for installing a Soil Gas Probe/Vapor Monitoring Point. Please note that this procedure is written for use by MDEQ staff and their contractors. Its use is optional for all others.

Soil gas samples collected less than five feet below ground surface must be referenced as shallow soil gas samples. Though these samples may provide beneficial information to support various lines of evidence, the effects due to barometric pressure, temperature, and the potential breakthrough of ambient air from the surface have the potential to cause these samples to be less reliable than soil gas samples collected at depths greater than five feet below the surface.

This SOP does not cover, nor is it intended to provide, a justification or rationale for where a sampling point is installed. It is assumed by using this SOP that site conditions have been fully evaluated and that the sampling location and depth meet the objectives outlined in the work plan or scope of work. For example, considerations must be given to the types of chemicals of concern, lithology encountered, surrounding buildings and underground structures, and the depth of the vapor source. Samples collected deeper than any potential source of vapors may not fully characterize the potential risk and sampling points should never be installed or collected within the zone of saturation.

2.0 SAMPLING POINT INSTALLATION

Prior to selecting sample locations, an underground utility search is required. Miss Dig and, if necessary, the local utility companies must be contacted and requested to mark the locations of their underground lines. Each sample location should also be screened in the field with a metal detector or magnetometer to verify that no underground utilities or structures exist.

2.1 Boring Advancement

There are many methods to advance a boring intended to install a soil gas sampling point. It is highly recommended that the methodology utilized have the following characteristics:

• Nominal in diameter (less than three inches is recommended)

• Provide minimal disturbance to the surrounding soil

• Does not inject air or water fluids

• Provides a soil core that can be screened, visibly classified, and if necessary collected for chemical analysis

A hydraulic probe is often utilized to advance a boring utilizing two different sampling devices. Those are:

• Open-tube sampling device – A direct push sampler for collecting continuous core samples of stable, unconsolidated materials.

Although other lengths are available, a standard macro-core sampler (MC5) available from Geoprobe® is available in lengths between 48 and 60 inches with an outside diameter of 2.25 inches (Figure 1). Soil is collected inside a removable liner. Macro-core

Figure 1. Example of an open-tube sampling device

2.2 Soil Gas Well Materials (General List of Materials)

Tubing – Sample probe tubing should be of a small diameter (1/8 to 1/4 inch) and made of materials that will not react or interact with target compounds. The size should also correspond to the size and construction of the sample point. Suggested materials are nylon, Teflon®, polyethylene, copper, polyvinyl chloride (PVC), or stainless steel. The choice of tubing type depends on site-specific considerations, but in general, nylon tubing is preferred as it exhibits lower adsorption rates and is more flexible and easier to work with than stainless steel

Soil Gas Well Screen – Screens must be less than six inches in length and configured to allow soil gas to enter along the entire length (Figure 3). This typically results in a fine mesh or screen being utilized to prevent dirt or other debris from entering into the sample tubing.

Sand Pack – The grain size of the sand pack should be sized appropriately (i.e., no smaller than the adjacent formation) and installed in a manner to minimize disruption of airflow to the sampling tip.

Bentonite – Bentonite is utilized to form a chemically resilient, low-permeability, flexible seal from above the well screen to the ground surface. In single vapor point well construction, granular bentonite or bentonite crumbles can be utilized. If multiple well screens are to be utilized, then a coated and compressed bentonite pellet or “tablet” must be utilized (1/4 inch) to prevent any bentonite dust from sealing portions

Figure 3. Vapor point examples

Standard Operating Procedure

Date: February 1, 2013

Installation of a Soil Gas Probe/Vapor Monitoring Point samplers are readily available and easy to use in most unsaturated soil conditions to at least ten feet below ground surface.

• Dual-tube sampling system – Dual-tube sampling systems are efficient methods of collecting continuous soil cores with the added benefit of a cased hole. Dual-tube sampling is beneficial in loose or unstable soils as a casing is advanced that prevents soil samples from falling into the boring (Figure 2).

Other methods for advancing boring include the use of hand augers, slab bars, and electric hammers. Each methodology has benefits and drawbacks and should be evaluated before a specific use is decided upon. The hydraulic probe methods identified above can be deployed in a wide variety of site conditions that allows the probe to be driven past some dense stratigraphic horizons.

Figure 2. Example of a dual-tube sampling device of the borehole. It must be noted that adequately sealing soil gas sampling probes is very important to minimize the exchange of atmospheric air with the soil gas and to maximize the representativeness of the sample.

2.3 Soil Gas Well Installation

The following procedure does not account for the advancement of the boring due to the number of available methodologies available; however, it is imperative that for each boring a soil boring log is competed that provides details on the soil conditions and potential contamination encountered. The procedure below starts after the boring has been advanced and may need to be modified based on the boring methodology utilized. Construction details for each point must be documented in a field log.

A. Inspect the borehole to ensure that it has remained open and is free of water to the depth were the well screen is to be placed.

B. Place four to six inches of sand pack on the bottom of the boring.

C. Pre-assemble screen and tubing and lower into borehole in an upright position on top of the sand pack. If the boring is deep and narrow, adding a small inert weight (e.g., nut) may be utilized to facilitate the tube reaching the bottom.

D. Cut the tubing and temporarily terminate the surface end with a Swagelok cap or other fitting to prevent debris from entering into the line.

E. Mark tubing using tape and a ball-point pen to identify the probe location and depth. All marks should be on tags attached to the tubing and not on the tubing itself. Note: Permanent markers must not be used.

F. Place sand pack around the screen and extend the sand pack to six inches above the top of the screen.

G. Confirm the depth to the top of the sand pack.

H. Record all measurements on the field log.

I. Place one foot of dry granular bentonite or bentonite pellets on top of the sand pack.

J. Avoid lateral movement between the tubing and the bentonite as much as possible once a point has been installed.

K. Install bentonite pellets until six inches below the next screen interval and then hydrate with minimal water or one foot from the ground surface ensuring that the bentonite does not bridge during the placement. If an additional vapor point in the same boring is to be installed, return to Step A and repeat.

L. Ensure that the final bentonite seal is at least 2.5 feet thick.

M. Cut the protruding lengths of tubing successively shorter so the deepest sample tube is the longest length and the others progressively shorter. This is helpful if the labels on each tube are lost or illegible upon resampling.

N. Terminate surface ends of tubes with Swagelok caps, valves, or other desired terminations.

O. Complete all required field documentation.

P. Unless soil gas points are to be abandoned the same day they are installed, probes must be properly secured, capped, and completed to prevent infiltration of water or ambient air into the subsurface. For surface completions, the following components may be installed, as necessary:

1. Fitting for connection to above ground sampling equipment

2. Protective flush-mounted or above ground well vaults; and/or

3. Guard posts

Examples of a single depth soil gas probe and a multi-depth or “nested” soil gas probe are shown in Figure

4. Figure 5 shows example pictures of surface completion.

Figure 5. Examples of various surface completions for vapor wells. (Hartman, 2004)

2.4 Soil Gas Well Abandonment

All vapor monitoring wells, including those used for soil gas monitoring, must be abandoned upon completion of site activities.

Vapor wells constructed in the manner identified above and that are less than 20 feet in depth may be abandoned by removing any tubing and all surface protective covers. The boring annulus can then be backfilled with uncontaminated native material or grout and returned as close as possible to original site conditions.

If the tubing cannot be removed, the tubing should be filled with liquid grout and cut off at least one foot below the ground surface. All surface protective covers must be removed and the boring annulus backfilled with uncontaminated native material or grout and returned to as close as possible to original site conditions.
