In addition to the control measures and effluent limits in Part III, the permittee shall implement the following to minimize pollutant discharges, as applicable:
Employee Training. Employee training shall include the following areas, at a minimum, as topics for applicable personnel:
Procedures for pest control.
Sector Specific Inspection Requirements.
In addition to the inspection requirements in Part IV.A, the permittee shall also inspect the following areas, if they are located at the facility:
Loading and unloading areas for all significant materials;
Storage areas, including associated containment areas;
Waste management units;
Vents and stacks emanating from industrial activities;
Spoiled product and broken product container holding areas;
Animal holding pens;
Staging areas; and
Air pollution control equipment.
Sector Specific Plan Requirements.
