Natural Gas Leak
& Corrosion Survey

In order to ensure the safe delivery of natural gas to your home or business, YCNGA conducts over 40,000 safety inspections each year.  These atmospheric corrosion and meter inspections are part of our routine safety practices and required by the Department of Transportation to be completed every three to five years on your property, or yearly if in a business district as defined by the Authority.

What is a Leak Survey?

A typical leak survey is performed by a technician who uses a leak detecting device and walks the area between the gas main, located in the street or alley, to your gas meter. The technician will require access to a portion of your yard depending on the distance and location of the service line and meter.  A typical survey does not require digging and will last just a few minutes.

Are utility representatives allowed on my property without my permission?

As a utility, our tariff states that authorized YCNGA employees or contractors have “full and free access to the premises of the customer at all reasonable hours.” Our contractors and employees have been instructed to knock on your door and ask for permission if they must enter your property through a gate before doing an inspection. If there is no answer, our representative will leave a notice and attempt to complete the survey at a later date.  For your safety and for regulatory compliance reasons, YCNGA will follow-up with a phone call, email, or letter to coordinate a time to complete this important inspection.

When are Inspections Held?

If you are an existing customer in our system, or have natural gas located on your property we will inspect your property every 3-5 years, or yearly if you are in a business district (as defined by the Authority).

YCNGA has contracted with Surview Field Services to complete the leak surveys and meter inspections.

Our employees and contractors carry identification and drive vehicles equipped with a YCNGA logo or contractor magnet with a YCNGA logo. Don’t hesitate to ask for identification if you see a technician on your property.

How can you help?

The survey is completed outside your home or business and will likely occur during normal business hours between 8am and 5pm. The technician completing the inspection will never ask to enter your home, but may knock on your door if the gas meter is located behind your home or in a gated area.

Please ensure that your meter is not blocked by shrubs or other debris.

If you receive notice that our inspector needs access to a gated area, please respond immediately so that we can complete the survey in a timely manner.  When the technician arrives, please leave gates unlocked and keep dogs away. Safety is a priority and these routine inspections help us maintain a safe and reliable source of energy for our customers.
