1. WATER QUALITY exceeds levels necessary to support public health, welfare, and the environment.
1.1 Existing water quality is not degraded.
1.2 Agricultural discharges or runoff do not harm water quality.
- Surface water quality monitoring is sufficient to characterize water quality in the MS River basin.
- Designated uses include existing and achievable uses.
- Ag discharges or runoff meet water quality criteria (numeric when possible) that protects designated uses in downstream surface waters.
- Maximum pollutant load allocations allow achievement of water quality criteria in downstream surface waters.
- Pollution loads are allocated to agricultural sources appropriately.
- Restoration plans are developed to reduce pollution from agricultural sources to a level at or under load allocations.
1.3 Point source discharges do not harm water quality.
- Surface water quality monitoring is sufficient to characterize water quality in the MS River basin.
- Designated uses include existing and achievable uses.
- Point source discharges meet water quality criteria (numeric when possible) that protects designated uses in downstream surface waters.
- Point sources do not discharge pollutants at levels which degrade existing high levels of water quality.
- Technology-based effluent limits are updated and expanded.
- Maximum pollutant loads are set and appropriately allocated to ensure water quality standards in downstream surface waters are met.
- Permit limits ensure water quality standards in downstream surface waters. (Permits reflect maximum pollutant loads and are met and enforced.)
1.4 Urban runoff pollution does not harm water quality needed to support public health, welfare, and the environment.
- Surface water quality monitoring is sufficient to characterize water quality in the MS River basin.
- Designated uses include existing and achievable uses.
- Urban runoff meets water quality criteria (numeric when possible) that protects designated uses in downstream surface waters.
- Maximum pollutant loads allow achievement of water quality criteria in downstream surface waters.
- Maximum pollutant loads are set and allocated to achieve/meet water quality standards in downstream surface waters.
- Best management practices for controlling urban runoff are implemented.
- Permit conditions include best management practices.
- Permit enforcement ensures permit conditions are met.
- Urban stormwater infrastructure is properly maintained.
