Your safety is our priority. The Customer-Owned Yard Line Program (COYL), available to eligible customers in Arizona, is part of that commitment to safety.
The COYL inspection and replacement program allows us to:
Not everyone has a COYL, but if you do, and you own a home or business in Arizona, Southwest Gas has a program you can take advantage of today!
The Arizona Corporation Commission, the state agency that regulates Southwest Gas, approved a program that enables us to inspect COYLs for leaks, with the customer’s permission. If a leak is found, we'll offer to relocate the meter as close as possible to the building, and will replace the primary COYL at no direct cost to you*.
*Exceptions may apply. Please contact Southwest Gas at 800-654-2765.
Southwest Gas will inspect and/or relocate the gas meter, replacing your primary COYL with facilities owned and operated by Southwest Gas.
In some cases, a COYL inspection must be conducted to determine if your COYL is eligible for replacement through the COYL program. The inspection process is free and generally takes less than an hour. Whenever possible, we try to conduct the inspection via an external leak investigation, which only requires access to the yard. Occasionally, we may need to do a pressure test, which requires entry into your home or business. A pressure test is typically required if landscaping, patios, pools, or other obstacles prevent the inspector from walking the route of the gas line. It’s easy to give your permission for the inspection by calling our Energy Specialists at 800-654-2765.
A Southwest Gas employee or contractor with proper identification will perform the COYL inspection.
If no COYL leak is found: Southwest Gas will let you know in person or we’ll leave a tag on your door. This is an ongoing program, so we’ll be back periodically to inspect your line again. And of course, should you suspect a leak, even if your line has been recently checked, call 911 and Southwest Gas immediately at 877-860-6020. For more natural gas safety information, click here .
If a COYL leak is found: Your gas service will be shut off immediately. To verify a leak, Southwest Gas or its contractor will need to enter your home or business. Southwest Gas representatives will discuss your options for restoring gas service as soon as possible, including replacing the primary COYL as part of this program.
