How long before construction must CNG Form 1500 be submitted?

The correct timeframe for submitting CNG Form 1500 is 30 days before construction begins. This requirement ensures that all regulatory and safety checks can be completed in a timely manner before the construction starts. The form acts as an application for constructing a CNG facility and allows the relevant authorities to review the proposed plans, assess compliance with safety standards, and address any potential environmental concerns. Submitting it too close to the construction date could hinder important evaluations and approvals, leading to delays or compliance issues. It is crucial to adhere to this 30-day notice to ensure a smooth and lawful construction process.
