HAVRE DE GRACE, Md. — As environmental groups and policy analysts in the Mississippi River basin seek solutions to shrink a massive “dead zone” that forms off the coast of Louisiana each year, they have looked to a regional clean-up program in the Chesapeake Bay as a model.

A key component of that effort, known as the Chesapeake Bay Program, is regulation.

For nearly 15 years, it’s included a legally enforceable, multi-state pollution quota — one of a select few in the nation. This “total maximum daily load” aims to reduce the amount of nutrients, like phosphorus and nitrogen, that run off into the Bay’s waters.
