The POTW shall, for all pollutants of concern, obtain sufficient data to allow the POTW authority to evaluate the need for local limits and shall set local limits if they are needed. Monitoring shall be done at a sensitivity adequate to evaluate the need for local limits and set local limits if needed.
Each POTW authority shall periodically re-evaluate its local limits and the need for local limits. The re-evaluation shall be done at least once every five years unless otherwise provided in the POTW's national pollutant discharge elimination system permit.
