Mechanisms¶
- Assimilation Capacity Assay
- It anchors a real regulatory construct: the assimilative capacity behind a Total Maximum Daily Load.
This sourceDefines the regulatory TMDL process as distributing a waterbody’s assimilative capacity among pollution sources and a margin of safety.
- It anchors a real regulatory construct: the assimilative capacity behind a Total Maximum Daily Load.
- Nutrient or Input Load Budget
- Rather than argue source by source, the regulator sets a Total Maximum Daily Load for phosphorus
This sourceDefines a TMDL as allocation within a waterbody's allowable loading capacity, including an explicit margin of safety, and gives a phosphorus example.
- Rather than argue source by source, the regulator sets a Total Maximum Daily Load for phosphorus
- Pollutant Load Reduction Plan
- A Total Maximum Daily Load allocation is the canonical form — a pollutant budget apportioned among sources with a margin of safety so the receiving water stays under its limit
This sourceDefines a TMDL as source-specific load allocations plus a margin of safety, set so receiving waters meet quality standards.
- A Total Maximum Daily Load allocation is the canonical form — a pollutant budget apportioned among sources with a margin of safety so the receiving water stays under its limit
