he defendant established Total Maximum Daily Load (TMDL) limits on nitrogen, phosphorus and sediment entering in the Chesapeake Bay and associated rivers and streams annually. The impacted states also developed individual plans as to how they would achieve the regulatory limits along with establishing two-year milestones for achieving regulatory compliance. The plaintiffs challenged the defendant's regulatory limits as exceeding the defendant's authority, but the trial court upheld the limits. On appeal, the court affirmed on the basis that the limits did not eliminate state flexibility to make cleanup decisions and how to reach pollution reduction targets.
