## PURPOSE and SCOPE OF WORK

The Bureau of Land and Waste Management Underground Storage Tank (UST)
Program of the South Carolina Department of Health and Environmental
Control (DHEC) is seeking services to perform active corrective action
of a petroleum release from a regulated underground storage tank site in
accordance with defined remediation goals. The objective is to remove
free product AND/OR reduce the levels of chemicals of concern (CoC) in
the ground water to or below defined site-specific target levels
(SSTLs). All offerors must be South Carolina Certified Class I Site
Rehabilitation Contractors. The scope of work defined in this
solicitation is to be implemented at \_\_\_\_\_\_\_\_\_\_ (UST Permit \#
\_\_\_\_\_\_), \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ \_\_\_\_\_,
\_\_\_\_\_\_\_\_\_\_, South Carolina for the release reported on
\_\_\_\_\_\_\_\_\_\_\_\_.

**SPECIAL CONDITIONS**

1.  CONTRACT PERIOD: The contract will be effective from date of award
    until the corrective action is complete as described in this
    contract.

2.  This contract is for active corrective action in addition to natural
    attenuation at only one (1) site in South Carolina. Compensation
    from the SUPERB Account is not considered a state contract for
    purposes of procurement or subject to state bid requirements in
    accordance with Section 44-2-130(D) of the SUPERB Act.

3.  AWARD: Award will be made to a South Carolina Certified UST Site
    Rehabilitation Contractor based on the total cost, method(s), and
    estimated time for active corrective action to SSTLs and removal or
    abandonment of assessment and rehabilitation items, provided the
    proposed implementation schedule to achieve the remediation goals,
    the removal of all equipment and abandonment of wells, (including
    pre-existing wells), trenches, etc. installed by the contractor, and
    the proposed remediation technology(ies) or method(s) are protective
    of public health and the environment and are eligible for permitting
    by DHEC. The total cost, methods, and estimated time to complete the
    contract must be advantageous to the State of South Carolina.

4.  REASONABLE COST: DHEC reserves the right to reject any and all bids
    that appear to be above the customary and reasonable cost for the
    same scope of work in a similar geologic setting, that propose a
    technology that cannot be permitted in the State of South Carolina,
    or that propose an estimated time frame for cleanup that is not
    protective of human health or the environment.

5.  Contractor must agree to make positive efforts to use women- and
    minority-owned businesses.

6.  AMENDMENTS: All amendments to this solicitation will be in writing
    from the DHEC Procurement Officer indicated on page one of this
    solicitation. DHEC will not be legally bound by any amendment or
    interpretation that is not in writing.

7.  QUESTIONS: Questions or requests for information must be submitted
    in writing and received by [5:00 P.M.]{.underline}, . After this
    date, no further questions will be addressed. A written response
    will be mailed to all requestors of the solicitation. The questions
    may be faxed to Henry Wigfall, fax number (803) 898-3505.

8.  **NOTE . . . THE ONLY OFFICIAL CONTACT PERSON AT DHEC DURING THE
    SOLICITATION AND AWARDING PROCESS IS THE PROCUREMENT OFFICER
    INDICATED ON PAGE ONE OF THIS SOLICITATION. OFFERORS ARE NOT TO
    CONTACT DHEC PERSONNEL LOCATED OUTSIDE THE BUREAU OF BUSINESS
    MANAGEMENT.**

9.  The contractor will be required to treat the area where the
    dissolved petroleum chemicals of concern are above site-specific
    target levels (see figure #2). Verification that interim corrective
    action goals have been met will be based upon ground-water quality
    samples collected from monitoring wells MW-\_, MW-\_, MW-\_\_,
    MW-\_\_, and MW-\_\_. Verification that final corrective goals have
    been met will be based upon ground-water quality samples collected
    from all existing monitoring wells, and additional verification
    wells to be installed at locations designated by SCDHEC (see
    specification #10 for more detail).

10. REPORTS: Deliver the reports to: SCDHEC, Bureau of Land and Waste
    Management, UST Program, ATTN: **PM**, 2600 Bull Street, Columbia,
    SC 29201. A minimum of two (2) copies of each plan and two (2)
    copies of each report must be delivered to the above address. Based
    on permitting and other requirements, an engineering report, UIC
    permits, air modeling forms or NPDES Permits may be required. Please
    contact the Department for the exact number of copies of each
    document to be submitted.

11. INVOICING: Invoices will be submitted to: SCDHEC, Bureau of Land and
    Waste Management, UST Program, ATTN: Financial Section, 2600 Bull
    Street, Columbia, SC 29201, using the Department's Corrective Action
    (CA) Invoice form. The initial invoice must be received at the above
    address within four months of CAP approval or funds will be
    uncommitted as required by the Section 44-2-40(B) of the SUPERB Act.

    funding is available. **Payment will only be made for achieving the
    corrective action goals as specified in this contract. No interim or
    partial payments will be made once corrective action is initiated,
    except as outlined in Specification #2.** Payment to the contractor
    will be a pay for performance system as follows:

A. Payment of forty percent (40%) of the total corrective action price
will be made within 90 days of operation of the remediation system or
implementation of corrective action as described in the approved
corrective action plan (CAP), subject to the limitations of Section
44-2-40 of the SUPERB Act. The implementation should be documented in
the first corrective action monitoring report.

B.  Payment of thirty-five percent (35%) of the total corrective action
    price will be made based on removal of free product to .01 foot as
    verified in monitoring wells **COPY 9** and achieving interim CoC
    mass reduction goals at the site as verified in monitoring wells
    **COPY 9.** Payment will be made for interim goals of 25, 50, and 75

\* CoC mass may change due to seasonal fluctuations in the groundwater.

(1) 25 percent total mass reduction will be achieved when free product
    has been removed to .01 foot from **COPY 9** and one-quarter of the
    initial BTEX, MTBE, and Naphthalene mass from monitoring wells
    **COPY 9 is** removed as compared to the SSTLs. The following
    formula will be used to calculate the percent total mass reduction:
    total mass above SSTLs from initial sampling [less]{.underline}
    total mass above SSTLs from subsequent sampling [divided
    by]{.underline} total mass above SSTLs from initial sampling.
    Payment of 10 percent (10%) of the total bid price will be made upon
    verification (see Specifications item 10 for the method of
    verification) of at least one-quarter of the total CoC mass above
    SSTLs is removed.

# Notes: If subsequent sampling indicates a CoC concentration at or below the SSTL and/or a CoC concentration at BDL but the reporting limit is at/or below the SSTL value for any constituent, the value for the mass reduction will be 0 (no negative numbers).

If subsequent sampling indicates a CoC concentration at BDL but the
reporting limit is above the SSTL, the value for any constituent will be
the analytical reporting limit.

C. **The final 25 percent (25%) of the total corrective action price
will be paid upon: 1) verification that the thickness of free product
does not exceed .01 foot and the levels of CoC do not exceed the
site-specific target levels (SSTLs) defined in item 11.C. at any point
in the area of concern (see figure #2). Verification that the SSTLs have
been met will be based upon ground-water quality samples collected from
all existing monitoring wells, and additional verification wells to be
installed at locations designated by DHEC (see specification #10 for
more detail); and 2) all remediation and assessment items installed by
the contractor (e.g., wells \[including preexisting wells\], trenches,
etc.) are removed from the site or properly abandoned.** The SSTLs are
as follows:

12. NOTIFICATION FOR FAILURE TO PERFORM: If the contractor fails to meet
    any specification of corrective action as outlined in this document,
    DHEC will notify the contractor by certified letter of the
    deficiency (ies). If the contractor does not correct the
    deficiency(ies) within 30 days, the contractor will be in breach of
    contract and the corrective action award may be voided by DHEC. DHEC
    will notify the contractor by certified letter that the bid award is
    void and any invoices are payable upon review and approval of DHEC.
    If the contractor corrects the deficiency(ies) within 30 days, the
    corrective action award will continue. Please note contractor-owned
    items used on-site for the contract that are destroyed by acts of
    nature, improper maintenance or handling, theft or vandalism will
    not be replaced or reimbursed by the SUPERB Account. [The accepted
    corrective action cost bid will be final and will not be increased
    or cancelled for any reason (e.g., unanticipated iron fouling of a
    system, wells clogging because of biological activity or sediments,
    increased subcontractor costs, loss of utilities, modification to
    the system to meet the remediation goals, etc.) with the exception
    of unforeseen geologic circumstances or identification of additional
    CoC from another release]{.underline}. **Payment will only be made
    for achieving the corrective action goals as specified in this
    contract. No interim or partial payments will be made once
    corrective action is initiated, except as outlined in Specification
    #2.**

13. SITE SPECIFIC DETAILS: A brief technical summary of the release,
    including a location map and specifics of existing wells, is
    attached. The detailed technical file will be available for review
    through the Freedom of Information (FOI) Office located on the third
    floor of the Sims Building, 2600 Bull Street, Columbia, SC. **Review
    of the detailed technical file is not mandatory; however, offerors
    are strongly encouraged to review the file to ensure a complete
    understanding of the contract requirements. The successful bidder
    will be responsible for all information included in the technical
    file.** Appointments to view the technical file may be scheduled on
    weekdays between the hours of 8:30 A.M. to 5:00 P.M. by calling the
    SCDHEC Freedom of Information Office at (803) 898-3882. Please
    request file #\_\_\_\_\_\_. ***NOTE: Free phase product may be
    present at this site. No free phase product was detected in the
    baseline-sampling event; however, application of corrective action
    technologies can result in the mobilization and possible appearance
    of free phase product or elevated CoC concentrations in the
    monitoring wells.*** The following facilities adjacent to the site
    have regulated USTs (operating/abandoned) registered with DHEC:
    \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, Permit ID#, (#O**/**#A),
    \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, Permit ID#, (#O/#A),

14. **The contractor will submit a Corrective Action Plan (CAP) within
    30 days of from the date the Purchase Order is issued from the
    Bureau of Business Management in accordance with Specification item
    2.** The implementation of the CAP will be initiated immediately
    upon Departmental approval of the CAP and all associated permit(s),
    and in accordance with the schedule presented in the CAP. A
    performance bond or irrevocable standby letter of credit, equal to
    the award price, will be required by DHEC. The issuing institution
    for an irrevocable standby letter of credit must be an entity that
    has the authority to issue letters of credit in South Carolina and
    whose letter-of-credit operations are regulated and examined by a
    federal or state agency. The original performance bond or
    irrevocable standby letter of credit will be submitted to the Bureau
    of Land and Waste Management, UST Program, Attn: Pat Holland, within
    30 days of award. The performance bond or irrevocable standby letter
    of credit will specify that the SUPERB Account will be the recipient
    of any forfeiture. Since DHEC is responsible for the disbursement of
    funds from the SUPERB Account, the financial responsibility
    mechanism (i.e., bond or letter of credit) will be held by the
    Bureau of Land and Waste Management, UST Program until the work is
    successfully completed.

15. **MINIMUM REQUIREMENTS: Corrective action will be considered
    complete once the levels of CoC in the area of concern (see figure
    #2) are verified to be at or below the SSTLs listed in item 11.C.,
    and removal or abandonment of all remediation and assessment items
    installed by the contractor (e.g., wells \[including preexisting
    wells\], trenches, etc.). See Specification #10 for the method of

> incurred (e.g., CAP preparation, obtaining performance bond, business
> license). The contract will be canceled and the performance bond or
> irrevocable letter of credit will be returned to the company. If the
> total CoC concentration in all wells listed in Special Condition 11.B.
> decreases more than 50 percent based on this initial sampling the DHEC
> may cancel the award. If the corrective action system is started or
> treatment is performed, the contractor will be required to complete
> the contract unless geological conditions change or another release is
> confirmed. See special condition 12. If the contract is canceled by
> DHEC, the contractor will be notified by certified letter and an
> invoice for the above outlined items shall be submitted within 20 days
> from the date of the certified letter canceling the contract.

2.  Complete and submit all applications for permits (injection, NPDES,
    BAQC modeling form, thermal treatment, construction, etc.; 3 copies)
    and an engineering report (ER; 4 copies) with the CAP. Any required
    permit changes or corrections will be submitted within 15 days of
    notification by DHEC. The ER and any ER amendments and
    modifications, must be sealed by a Professional Engineer registered
    in the State of South Carolina. After review of the CAP and all
    permit applications by DHEC, the Bureau of Land and Waste
    Management, UST Program will issue a notice to proceed with CAP
    implementation.

> Implementation of the corrective action plan before the completion of
> the public notice process and approval of all permits by DHEC is not
> authorized. If premature implementation occurs, the Department will
> not reimburse those costs from the SUPERB Account, and the bid award
> will be reduced by that amount. If the Department agrees with early
> implementation to better protect human health in an emergency and
> provides approval in writing, early implementation without any
> reduction to the bid amount will be authorized.

3.  Implement the CAP within 30 days of receipt of notice to proceed and
    any required permit to construct. Disruption to the owner/operator's
    normal business will be kept to a minimum. The contractor will
    repair the site to the condition as it existed prior to installation
    of the corrective action system (e.g., asphalt paved areas will be
    repaved with asphalt, concrete areas will be replaced with concrete,
    grass areas will have soil replaced to the original grade and
    reseeded or sodded with grass, etc.) Upon completion of any required
    construction, DHEC will inspect the system and issue a permit to
    operate. The contractor will, at all times, keep the site free from
    waste materials and rubbish related to the corrective action. Until
    completion of the corrective action, the contractor will keep the
    premises in a clean, neat and workmanlike condition satisfactory to
    DHEC. All generated soil and wastewater will be removed from the
    site promptly. Manifests documenting the proper disposal of the soil
    and wastewater must be included in the appropriate report.

4.  Gain access to the adjacent property to sample monitoring wells and
    to install any corrective action equipment, as required. The
    contractor will repair the site to the condition as it existed prior
    to installation of the corrective action system (e.g., asphalt paved
    areas will be repaved with asphalt, concrete areas will be replaced
    with concrete, grass areas will have soil replaced to the original
    grade and reseeded or sodded with grass, etc.)

16. Initiate system startup within 15 days of receipt of the permit to
    operate. Remediation as defined in the CAP and ER will begin upon
    system startup. **If any problem with CAP implementation occurs, the
    contractor will contact the UST project manager within 24 hours of
    problem identification and will submit written documentation within
    five days of notification. *NOTE: Free phase product may be present
    at this site. No free phase product was detected in the
    baseline-sampling event; however, application of corrective action
    technologies can result in the mobilization and possible appearance
    of free phase product or elevated CoC concentrations in the
    monitoring wells. ***The following facilities adjacent to the site
    have regulated USTs (operating/abandoned) registered with DHEC:
    \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, Permit ID#, (#O**/**#A);

7.  Properly dispose of all contaminated soil and ground water generated
    during the implementation of the CAP and installation of
    verification wells. DHEC must approve the disposal facility selected
    for treatment and disposal of the free product and contaminated soil
    and ground water. The owner/operator of the facility is considered
    the generator for any contaminated soil and ground water. The
    contractor must document all disposal of free product and
    contaminated soil and ground water in the quarterly corrective
    action monitoring report.

8.  Verification for the removal of free product will be conducted by
    SCDHEC personnel with an interface probe. If the remediation
    technology is in-situ (e.g., pump and treat, air sparging, vapor
    extraction): suspend operation of the system once the remediation
    goals for all CoC have been maintained for a period of 30 days.
    Samples are to be taken after one (1) quarter or after all CoC
    levels have reached equilibrium and again after a second quarter.
    Along with the parameters listed in Specification #8, the
    ground-water samples should also be sampled for the following
    parameters:

> \*or EPA equivalent method that can achieve the same reporting level

If sample results indicate that the remediation goals are not sustained,
the contractor must submit a corrective action status report (3 copies)
that outlines the deficiency(ies) and offers recommendations for
achieving the remediation goals with a revised timetable. Modifying and
restarting of the system may be directed by DHEC. All remediation goals
must be again maintained for a minimum of 30 days. Corrective action
will then be suspended again and samples taken to verify that
remediation goals are sustained. This cycle of activity, including
status reports, will be repeated until all CoC levels remain below SSTLs
for all wells listed in Special Conditions item 11 C for two (2)
consecutive quarters. **(#\_\_\_\_\_\_\_)** Verification wells may be
installed at locations designated by DHEC. Costs for verification well
installation are considered part of this bid price. Each well will be
sampled in accordance with Specifications item 8. and the analyses
compared to the calculated SSTLs for the CoC at that well location. If
the laboratory analyses are at or below the SSTLs, corrective action
will be considered complete. If any analysis is above the SSTL, the
corrective action will not be considered complete, and the activity
cycle described above must be repeated until all CoC levels remain below
SSTLs for those wells listed in Special Conditions item 11 C. Split or
duplicate samples may be collected by DHEC (or its subcontractors) to
verify achievement of remediation goals. In addition to the ground water
collected from the monitoring wells, the UST Program may provide up to
three standards or prepared blanks for the contractor's laboratory to
analyze. The laboratory analysis from the contractor's and the UST
Program's laboratory will be compared. In the event of substantial
variance (more than 15%), a second sampling event with field and trip
blanks will be sent to a SC certified laboratory by the UST Program for
analysis. The contractor will be notified when the wells will be
resampled, can observe this second sampling event, and will be provided
analytical results for comment. DHEC Laboratory Certification will be
provided copies of all sample data sets with all relevant quality
assurance/quality control data to assist the UST program in determining
the cause of a laboratory variation. The Director of the Assessment and
Corrective Action Division will make the final decision on which
analytical values will be the basis for payment or closure based on the
recommendation of the site rehabilitation contractor, DHEC Laboratory
Certification, the UST Section Manager, and the UST Project Manager. The
site rehabilitation contractor will be provided a written record of any
decision. **At least two weeks notice will be provided to the UST
Project Manager prior to mobilizing to the site for sampling to verify
attainment of remediation goals.** Costs for transportation and analysis
of split or duplicate samples will be paid by DHEC.

9.  Disassemble and remove the remediation system and all associated
    remediation items including utilities from the site within 60 days
    of notification by DHEC that the remediation goal for the release
    associated with the UST(s) at the site has been achieved. Disruption
    to the owner/operator's normal business will be kept to a minimum.

10. Properly abandon all monitoring, recovery, and/or injection wells
    (including preexisting wells), borings, trenches, and piping/utility
    runs installed by the contractor as part of corrective action within
    60 days of notification by DHEC that the remediation goal for the
    release associated with the UST(s) at the site has been achieved.
    The abandonment will be in accordance with South Carolina Well
    Standards and Regulations R. 61-71 and accepted industry standards
    for abandonment of trenches and piping/utility runs. Disruption to
    the property owner's normal business will be kept to a minimum. The
    contractor must notify DHEC of the method of well abandonment and
    final disposal of any free product and contaminated soil or ground
    water. The contractor will return the site to the condition prior to
    corrective action (e.g., asphalt paved areas will be repaved with
    asphalt, concrete areas will be replaced with concrete, grass areas
    will have soil replaced to the original grade and reseeded or sodded
    with grass, etc.).
