UNDS Phase II Batch One: National Consistency Determination

The National Consistency Determination for the Uniform National Discharge Standards (UNDS) Batch One rulemaking is prepared in compliance with the Federal Coastal Zone Management Act (CZMA) of 1972, Section 307 (Title 16, United State Code (U.S.C.) Section 1456(c)), which states that federal actions must be consistent with approved state coastal management programs to the maximum extent practicable. A National Consistency Determination is the appropriate mechanism to address coastal effects and concerns because UNDS is a national rulemaking that could have an effect on numerous coastal zones. Based on the data presented in the National Consistency Determination, the EPA and the Department of Defense have concluded that the proposed UNDS Phase II Batch One performance standards are consistent to the maximum extent practicable with the enforceable policies of each of the 35 federally-approved state and territory coastal management programs.
