What is the purpose of reserve capacity in a TMDL?

Reserve capacity in a TMDL acts as a margin of safety within the total allowable pollutant load. It is set aside to account for future growth and uncertainties in measurements, models, and pollution sources. As populations expand, land use changes occur, and predictions drift, this reserved portion helps keep water quality protections intact without having to rewrite the TMDL every time conditions change. It provides flexibility to absorb unexpected increases in load while staying within the overall limit. It isn’t about letting more pollution through or boosting treatment directly, and it doesn’t aim to eliminate all loadings. It’s simply a buffer to maintain protection over time as circumstances evolve.
