Gas Line Repair in Longmont, CO
78% of households in Longmont take mains gas. Two things follow: there is a buried line on the property, and somebody other than you is responsible for part of it.
Read this first
A buried service line and a meter sit on most properties in Longmont, where 78% of homes are on mains gas. Federal rules end the utility's service line at the meter outlet, so everything downstream of the meter is the owner's to maintain and repair.
Source: US Census Bureau, American Community Survey table B25040; the service line boundary is 49 CFR § 192.3.
If you smell gas right now
Leave the building on foot. Do not use a phone or a light switch inside. Call 911 and your gas utility from somewhere else, and do not call us — we are a referral service, not an emergency line. The full list, in order.
How Longmont is supplied
A buried run from the street to a meter, and piping onward through the property. Federal rules end the service line at the meter outlet; what comes after is customer piping.
The piping people forget they own is the buried run from the meter to a detached garage, a grill or a pool heater. That is theirs, and it may not be marked when somebody comes to locate lines.

B25040 is a fuel count, not an infrastructure count. It tells you what burns in these houses, from which the arrangement follows — but it is an inference, not a meter reading. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Colorado as a whole, 68% of households are on mains gas and 3% on tank propane. Longmont sits 9 points above the state on mains and 1 point below it on propane. That spread is what a state average hides, and it is why this page carries the town’s own figures rather than inheriting them.
Before anyone digs on the property
The single most dangerous thing most people will ever do to a gas line is put a spade through it. PHMSA calls excavation damage the leading cause of pipeline incidents; 8-1-1 is a nationwide toll-free number to call before any excavation, and calling it gives a 99 percent chance of avoiding an incident.

What to ask whoever quotes it
Ask which side of the meter the work is on before anything else. On the utility side it may not be a contractor job at all, and a quote that has not established that has not established whose problem it is.

Checking a plumber in Colorado
Colorado licenses are issued by the Colorado State Plumbing Board, Division of Professions and Occupations, which publishes a public search you can use before work begins.
Gas work is separately permitted and separately licensed in most jurisdictions, so ask specifically about gas rather than plumbing in general.
For repair work, not for a suspected leak.If you can smell gas, leave and call 911 or your utility from outside; this is the wrong number for that. For everything else — a line, a meter, an appliance connection — we will route you to a contractor covering your area, free of charge to you. Non-emergency work in Longmont goes through this number as well.
