Gas Line Repair in Conowingo, MD
Tank propane heats 24% of homes in Conowingo. There is no service line here in the federal sense, which sounds like a technicality and is actually the whole difference.
Read this first
24% of households in Conowingo use bottled or tank gas, which puts the supply on the property rather than under the street. There is no utility service line and no meter boundary: the tank, the regulator and the line to the house belong to the owner or the gas supplier by contract.
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 Conowingo is supplied
A tank, a regulator, and buried line between them and the house. All of it is the property owner’s, and none of it sits under the federal service line definition that governs a mains connection.
That makes the buried run private buried line — which is exactly the sort a standard locate may not mark before somebody digs.

| Utility (mains) gas | 4% |

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 Maryland as a whole, 45% of households are on mains gas and 3% on tank propane. Conowingo sits 41 points below the state on mains and 21 points above it on propane. The state number would tell you something true about the state and very little about here, which is why it is not the number above.
Before anyone digs on the property
Excavation damage remains the leading cause of pipeline incidents according to PHMSA. That is not a fact about pipelines so much as a fact about gardening, and the prevention is one free call to 8-1-1 before the first spade goes in.

What to ask whoever quotes it
Ask them to describe the fault before they price it. "The line needs replacing" is not a diagnosis, and on a buried run the difference between one damaged point and a line at the end of its life is most of the cost.

Checking a plumber in Maryland
Maryland licenses are issued by the Maryland State Board of Plumbing, Department of Labor, 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. Other Conowingo requests are covered by the same line.
