Description
The State of Illinois, Environmental Protection Agency, is soliciting a change order notice for the TMDL Tetra Tech project. The project involves adding additional funding to address fecal coliform impairments in four additional watersheds in the Spoon River watershed. Tetra Tech proposes to provide technical support for TMDL and implementation plan development. The key aspects of the project include:
• TMDL and IP development for four additional watersheds
• Addressing fecal coliform impai... | Title: CHANGE ORDER NOTICE-TMDL Tetra Tech, Agency: Illinois EPA - Environmental Protection Agency, State: Illinois, Open Date: 3/5/2026, Close Date: 3/19/2026, Last Updated Date: 3/19/2026

BidPulsar Analysis
A practical, capture-style breakdown of fit, requirements, risks, and next steps.
The Illinois Environmental Protection Agency (State of Illinois) is issuing a change order notice for the existing “TMDL Tetra Tech” project. The change adds funding to address fecal coliform impairments in four additional watersheds within the Spoon River watershed. Tetra Tech proposes to provide technical support for Total Maximum Daily Load (TMDL) and Implementation Plan (IP) development for these additional watersheds. This appears to be a contract modification scenario (not a new competitive procurement), open 3/5/2026 and closing 3/19/2026 per the notice text.
Increase scope/funding under the existing TMDL effort to cover fecal coliform impairments by developing TMDLs and associated implementation plans for four additional watersheds in the Spoon River watershed, using Tetra Tech for technical support.
- Likely only the incumbent prime (Tetra Tech) if Illinois EPA is processing a contract change order/modification rather than a competed solicitation
- Develop TMDLs for fecal coliform impairments for four additional watersheds in the Spoon River watershed
- Develop Implementation Plans (IPs) tied to the new TMDLs for the four additional watersheds
- Provide technical support to Illinois EPA for TMDL and IP development activities under the change order
- Written confirmation of understanding of the added scope: TMDL + Implementation Plan development for four additional watersheds (Spoon River watershed) focused on fecal coliform impairments
- Technical approach describing how fecal coliform impairments will be analyzed and translated into TMDL and implementation plan deliverables for four watersheds
- Staffing plan identifying the technical support team for TMDL/IP development
- Cost/price proposal for the additional funding requested under the change order (as applicable to the contracting mechanism)
More BidPulsar strategy notesCompliance, pricing, teaming, risks, questions, and coverage notes
- Notice is explicitly described as a “change order notice” for the “TMDL Tetra Tech project,” indicating a modification context rather than a new open competition
- Open and close dates appear in the description text: Open Date 3/5/2026 and Close Date 3/19/2026
- Structure pricing around incremental scope only (the four additional watersheds and fecal coliform impairment work) to align with a change-order/modification intent
- Ensure price narrative clearly ties added funding to discrete deliverables: four watershed TMDLs and four implementation plans, plus defined technical support tasks
- If allowed under the existing contract vehicle, consider specialized local watershed or monitoring SMEs to strengthen fecal coliform source characterization inputs to the TMDL/IP work
- High likelihood this is non-competitive (incumbent-only) as a change order notice; non-incumbents may waste bid resources unless Illinois EPA confirms competition is intended
- Scope details are truncated in the notice text (ends mid-sentence), creating risk of missing required methods/deliverables unless the full notice/attachments are obtained
- No place of performance, period of performance, or deliverable schedule provided in the brief, which can materially affect cost and resourcing
- Is this notice strictly a contract change order/modification to an existing Tetra Tech contract, or is Illinois EPA seeking competitive responses?
- What are the names/IDs of the four additional watersheds in the Spoon River watershed being added?
- What specific deliverables are required for each watershed (e.g., TMDL report, modeling files, stakeholder materials) and in what formats?
- What is the period of performance for the added scope and are there interim milestones tied to the 3/19/2026 close date?
- What is the not-to-exceed amount or additional funding ceiling contemplated for this change order?
- Are any new data collection/monitoring activities required for fecal coliform, or is the TMDL/IP development based on existing datasets?
Some notices publish limited source detail. Confirm these points before final bid/no-bid decisions.
- Whether this change order notice is open for competitive bidding or is incumbent-only
- Identity/names of the four additional watersheds included in the added scope
- Full untruncated scope statement and required deliverables for TMDL/IP development
- Contract vehicle details and instructions for submitting a response (if any)
- Period of performance and milestone schedule for the added work
- Budget/not-to-exceed amount or pricing structure for the additional funding
- Place of performance and stakeholder engagement expectations (if applicable)
