Submission of Responses

• Submit the Response by the due date and time on the Cover Page using FTPS, as specified under Submission Procedures section. TCEQ will not consider Responses submitted via any other method.

• If the Response lacks required information or does not follow these instructions, the Response may be considered non-responsive and disqualified. TCEQ is not responsible for documents that cannot be read. Unreadable Responses may be, at TCEQ’s discretion, rejected as non-compliant.

https://www.comptroller.texas.gov/purchasing/vendor/hub/forms.php

• Responses cannot be altered, amended, or withdrawn after the Due Date and Time. To withdraw a Response prior to the Due Date and Time, the Responder must submit the request to: leslie.delvige@tceq.texas.gov.

Due Date/Late Responses

It is Responder’s responsibility to ensure timely delivery of the Response to TCEQ by the date and time on the Cover Page of this Solicitation. Except under extreme circumstances beyond the control of the Responder, late Responses will not be considered. TCEQ will not be responsible for the failure of email services.

TCEQ’s Acceptance of Responses

TCEQ may reject Responses that do not comply with requirements in the Solicitation and state and federal laws. TCEQ may accept or reject all or any part of any Response, waive procedures for submitting Responses, waive formalities and/or minor technicalities, and award by item or groups of items, whichever best serves the interests of TCEQ. TCEQ may also cancel this procurement and withdraw this Solicitation at any time before a contract is signed by TCEQ. TCEQ shall have sole discretion of what is in the best interests of TCEQ.

Evaluation

The pricing and all terms and conditions of Responses are fixed for 120 days from receipt by TCEQ. Best and Final Offers (BAFOs), if requested by TCEQ, are fixed for 60 days. To determine the most advantageous Response, in addition to price, TCEQ may consider other relevant criteria, which are described more fully in Section 2, Evaluation Criteria. TCEQ may use information regarding the Responder’s performance on past TCEQ contracts in the evaluation of qualifications. In addition, TCEQ will use the information contained in the Texas Comptroller of Public Account’s vendor performance tracking system in the evaluation of qualifications.

Selection

Depending on the applicable procurement method and solicitation type, in order to secure the best value for the State, TCEQ may take one or more of the following actions in the selection process:

• Accept the highest scoring Response without changes.

• Request clarifications, assurances, and corrections.

• Modify the selection criteria and apply it to BAFOs, provided that the modifications do not materially affect initial applicant eligibility or invitation to submit a BAFO.

Conduct discussions on Responses scoring within a competitive range and request Best and Final Offers (BAFOs).

• Select the highest scoring BAFO and accept it without changes or negotiate acceptable terms.

• Award one or more contracts based on the amount of work that TCEQ foresees needing performed.

• Award contracts to other contractors at a later date under this Solicitation or through another appropriate method, including another solicitation.

• In the case of a tie that cannot be resolved by application of one or more statutory preferences, make a selection, in the best interest of the State, by drawing lots, mailto:leslie.delvige@tceq.texas.gov tossing a coin, or drawing names with two witnesses to oversee the tiebreaking activity.

Certification of Interested Parties

Section 2252.908 of the Texas Government Code states that a state agency may not enter into certain contracts with a business entity unless the business entity submits a disclosure of interested parties (Form 1295) to the state agency at the time the business entity submits the signed contract to the state agency. The contract is voidable if the business entity fails to provide the disclosure of interested parties as required by statute.

Form 1295 must be filed electronically through the Texas Ethics Commission at https://www.ethics.state.tx.us/filinginfo/1295/ . The web site includes a list of Frequently Asked Questions.

The selected vendor(s) for a contract that meet the requirements to provide a Certification of Interested Parties will be given instructions at the time of award on how to submit the certification form.

Protest Procedures

An actual or prospective Responder or Contractor who is aggrieved in connection with the Solicitation, evaluation, or award of a contract by TCEQ may formally protest to the TCEQ Manager of Procurements and Contracts. TCEQ Protest Procedures can be found at 30 Texas Administrative Code Part 1, Chapter 11, Subchapter B, § 11.2.
