What is the main purpose of the OQ regulation?

The main purpose of the OQ regulation, which stands for Operator Qualifications, is to ensure operator competency and safety in the operation and maintenance of natural gas systems. This regulation mandates that individuals responsible for operating these systems are adequately trained and assessed for their knowledge and skills. The focus is on verifying that operators understand the safety protocols, emergency procedures, and overall functioning of the gas systems they manage. Compliance with OQ regulations helps to minimize the risk of accidents and ensures that operations are conducted safely and efficiently.

Other options, while relevant in various contexts, do not reflect the primary intent of the OQ regulation. Enhancing customer relations, prescribing installation methods, and monitoring environmental impacts are important aspects of the broader gas industry but are outside the direct scope of operator qualification. The emphasis on operator competency and safety is crucial for protecting both the workers involved and the public, making it the correct answer.
