Each of the utilities involved in the formation of ATC contributed its own methods and standards of how work in the field was accomplished. ATC Business Practices describe how ATC and its interconnected customers deal with costs, roles and responsibilities for specific technical or business-related issues. They are created by soliciting input from internal and external stakeholders, while balancing the needs and concerns of ATC and its customers. They provide clear and consistent guidelines to allow ATC to provide timely, cost-effective and comparable service to all customers.
