My intent in providing these…

My intent in providing these comments is not to oppose development in principle, but to ensure that the application before the Ministry is complete, technically defensible, and sufficiently protective of the receiving environment, particularly under conservative and worst-case conditions. Given the ecological importance of the Goulais River and its role within the broader watershed, a high standard of review is warranted.

Based on my review of the Design Brief and referenced supporting materials, I respectfully submit the following comments for the Ministry’s consideration.

1) Application Completeness and Internal Consistency:

The Design Brief contains internal errors, incomplete cross-references, and reliance on studies and appendices that are identified as *in progress* or *to be provided when available* (e.g., Sections 4.1.4, 4.2.2, and Appendices related to the updated EIS and archaeological assessments).

In addition, formatting and referencing errors (e.g., broken bookmarks and inconsistent section numbering) reduce confidence that the submission represents a finalized, quality-assured record.

Why this matters:

An ECA decision relies on a complete and internally consistent evidentiary record. Where conclusions depend on studies that are not yet finalized or appended, it becomes difficult for regulators or the public to meaningfully assess risk, mitigation effectiveness, or cumulative impacts.

I respectfully request that the Ministry confirm the application is administratively complete and require submission of all finalized studies and corrected materials prior to any approval decision.

2. Reliance on the Assimilative Capacity Study (ACS) Without Demonstrated Worst-Case Analysis

The Design Brief repeatedly relies on the Assimilative Capacity Study (ACS) to conclude that the Goulais River can safely receive treated effluent (e.g., Sections 4.1.5, 4.1.6, and 5.4.3). However, the materials provided do not clearly demonstrate that the ACS evaluates **worst-case receiving water conditions**, including:

- critical low-flow periods,
- warm-season water temperatures,
- coincident peak effluent discharge (up to 360 m³/d, Section 5.3), and
- reasonable treatment upset or operational variability.

The ACS appears to rely primarily on steady-state or average conditions rather than conservative scenarios.

Why this matters:

Assimilative capacity is lowest when rivers are under the greatest natural stress. Without explicit evaluation of low-flow and warm-temperature conditions, it is difficult to verify that modeled compliance translates into real-world environmental protection, particularly for sensitive aquatic species.

I respectfully request that the Ministry require clarification or an ACS addendum demonstrating that effluent limits remain protective under worst-case seasonal and hydrologic conditions.

Water-Taking / Withdrawal Not Clearly Integrated into the ACS

The Design Brief does not clearly demonstrate that authorized or operational water withdrawals by the Resort have been incorporated into the assimilative capacity analysis.

Water withdrawals can reduce instream flow during critical periods, directly affecting dilution capacity, thermal resilience, and ecological thresholds. This is particularly relevant where water is withdrawn from, and effluent is discharged to, the same watershed.

Why this matters:

Assimilative capacity is fundamentally a flow-dependent calculation. Excluding or under-representing water withdrawals risks overstating the receiving environment’s capacity and underestimating cumulative stress.

I respectfully request that the Ministry require explicit integration of water-taking volumes, timing, and seasonal effects into the ACS, including a clear water balance analysis for low-flow conditions.

Planning Timeline and Compliance Assurance:

The submission references prior engagement with regulatory agencies regarding wastewater capacity (notably discussions occurring around 2020), as well as the issuance of an MECP Order related to site operations. This suggests that development and operational pressures may have preceded the establishment of approved treatment capacity.

While this does not preclude approval of a properly designed system, it highlights the importance of **strong compliance assurance and growth controls** moving forward.

Why this matters:

Where wastewater infrastructure is constructed after capacity constraints are already present, approvals should include safeguards to ensure that future loading does not outpace verified treatment performance.

I respectfully request that the Ministry consider enforceable ECA conditions that link treatment capacity, monitoring results, and compliance performance to any future increases in use or occupancy

Monitoring, Transparency, and Adaptive Management

Given the sensitivity of the Goulais River and the reliance on modeled outcomes, I request that any approval include:

- enhanced effluent and receiving-water monitoring requirements, including during low-flow and warm-season periods;
- transparent public reporting of monitoring results; and
- clearly defined response actions should exceedances or system failures occur.

Why this matters:

Monitoring and transparency are essential to confirm that predicted performance aligns with real-world conditions and to maintain public confidence in the approval process.

Closing:

In summary, I respectfully request that the Ministry ensure this application is:

- complete and internally consistent,
- supported by conservative, worst-case environmental analysis,
- inclusive of all relevant watershed pressures (including water withdrawals), and
- subject to enforceable conditions that protect the Goulais River over the long term.

These comments are offered in good faith to strengthen the integrity of the review process and support informed, evidence-based decision-making.

Thank you for the opportunity to provide input.
