SUMMARY:811 Day is August 11, 2026: What Oil and Gas Contractors Need to Know Before Digging
DESCRIPTION:August 11 reinforces the nationwide call-before-you-dig system, with a state-by-state directory for pipeline, facility and industrial excavation planning.\nPublished by Allstream Insiders.\nAllstream Insiders Summary\n811 Day is observed on August 11 — 8/11 — as a nationwide reminder to contact 811 before starting an excavation. A locate request alerts participating underground-facility owners and operators so they can respond and identify facilities that may conflict with the planned work.\nFor the oil and gas industry, the process applies far beyond mainline pipeline construction. It can affect excavation around gathering systems, well pads, compressor and processing facilities, terminals, refineries, LNG facilities, tank farms, utility crossings and rights-of-way.\nThe Pipeline and Hazardous Materials Safety Administration says excavation damage remains the leading cause of pipeline incidents across the nation’s 3.3 million miles of pipeline. PHMSA also reports that research shows contacting 811 before digging provides a 99% chance of avoiding an incident, injury, environmental harm or death.\nThe number is national, but the rules are not identical in every state. Required notice periods, ticket life, tolerance zones, positive-response procedures and emergency requirements vary. The state-by-state directory below provides each jurisdiction’s official one-call center, direct phone number and website.\nWhat Is 811 Day?\n811 Day uses August 11 to reinforce the three-digit number contractors, utilities and property owners use before excavation. The observance is supported by PHMSA, the Common Ground Alliance and state one-call centers as part of the broader effort to prevent damage to underground infrastructure.\nCalling 811 or submitting a request through a state center’s website does not send a federal inspector or a single nationwide locating crew. The one-call center creates a ticket and notifies participating facility owners or operators whose registered service areas overlap the proposed excavation. Those companies then respond, typically by marking their facilities or issuing a positive response that no conflict exists.\nThe locate-request service is generally free to the excavator. However, private or nonmember facilities may not be included. Industrial sites, refineries, terminals, plants, well pads and other privately operated properties may therefore require additional operator coordination, site drawings and a private utility locator.\nWhy 811 Matters to the Oil and Gas Industry\nExcavation damage can affect the pipe itself and the systems that protect or operate it. PHMSA’s federal excavation rules define damage broadly enough to include impacts requiring repair or replacement of pipe, protective coating, supports, cathodic-protection components or related facilities.\nOil and gas work that may require a locate request includes:\n\nPipeline trenching, replacements, tie-ins and integrity digs.\nRoad, railroad, utility and foreign-pipeline crossings.\nWell-pad, gathering-line and produced-water construction.\nCompressor-station, gas-processing and fractionation work.\nTerminal, tank-farm, refinery, petrochemical and LNG excavation.\nFoundations, grading, fencing, drainage and access-road work.\nBoring, drilling, piling, vacuum excavation and soil sampling.\nMaintenance work near buried electrical, fiber, water, sewer, instrument-air or control systems.\n\nAn unplanned strike can injure workers, release natural gas or hazardous liquids, damage coatings, interrupt production and trigger emergency response. It can also create a latent integrity concern even when there is no immediate leak. For that reason, PHMSA requires pipeline damage to be reported to the operator at the earliest practical moment, whether or not a release occurs. If excavation damage causes a release, the excavator must also call 911.\nHow the 811 Process Works Before Excavation\nA valid ticket begins the damage-prevention process; it does not by itself authorize excavation. Contractors should also satisfy the applicable permit, right-of-way, operator, facility and job-safety requirements.\n\nDefine the work area. Identify the excavation limits, scope, method and expected start date. White-line or electronically map the proposed area when required or useful.\nContact the correct state center. Dial 811 from the state where the work will occur or use that center’s online ticket system. For multistate projects, create the required tickets in each jurisdiction.\nWait the state-required period. Do not use a generic 48- or 72-hour assumption. Follow the timing shown by the applicable state center and account for weekends and holidays.\nConfirm every response. Check the ticket’s positive-response record and verify that each notified facility owner has marked, cleared or otherwise responded to the request.\nReview the site before digging. Compare the field markings with visible facilities, records and the planned work. Stop and seek a re-notification or operator response if something does not match.\nExpose and excavate carefully. Follow the state’s tolerance-zone requirements and the facility owner’s procedures. Marks identify an approximate horizontal location and should not be treated as proof of depth.\nProtect the marks and ticket. Preserve markings, monitor ticket expiration and request a remark or update when the work continues beyond the allowed period or marks are no longer usable.\nReport any contact. Notify the facility owner promptly about a scrape, dent, coating disturbance, cathodic-protection contact or other damage, even without a leak. Move to a safe location and call 911 when a release or immediate hazard exists.\n\nNo crew should assume that another contractor’s ticket, a previous project ticket or an operator’s internal drawing automatically covers its company, excavation limits, method and schedule. Coverage and ticket-transfer rules are state-specific.\nUnderground Utility Marking Colors\nYellow is the principal marking color for gas, oil, steam, petroleum and other gaseous materials. The Common Ground Alliance’s Best Practices guide lists the APWA uniform color code used nationwide, subject to any different state requirement.\n\n\n\nMarking color\nTypical meaning\n\n\n\n\nWhite\nProposed excavation\n\n\nPink\nTemporary survey markings\n\n\nRed\nElectric power lines, cables, conduit and lighting cables\n\n\nYellow\nGas, oil, steam, petroleum or gaseous materials\n\n\nOrange\nCommunications, alarm or signal lines, cables or conduit\n\n\nBlue\nPotable water\n\n\nPurple\nReclaimed water, irrigation and slurry lines\n\n\nGreen\nSewers and drain lines\n\n\n\nState-by-State 811 Contact Directory\nDial 811 from the state where the excavation will occur.

A locate request does not replace a right-of-way agreement, crossing permit, facility work authorization, pipeline-operator representative, job safety analysis or the requirements for working near a regulated pipeline.\nBefore releasing an excavation crew, project teams should be able to answer:\n\nDoes the ticket match the excavator, work area, method and schedule?\nHas every notified operator issued a positive response?\nAre the markings consistent with site records and visible facilities?\nCould private, abandoned or nonmember lines be present?\nWhat state tolerance-zone and exposure rules apply?\nDoes the facility owner require a representative, standby or crossing procedure?\nIs the ticket current, and are the marks protected and visible?\nDoes the crew know whom to call for a damage, suspected contact or release?\n\nAllstream Perspective\n811 Day gives operators, contractors and facility owners a useful date for reinforcing a year-round responsibility. The practical value is not the awareness campaign alone; it is the discipline of making the locate request early, confirming every response and resolving discrepancies before equipment enters the ground.\nThat discipline is especially important in congested oil and gas corridors where transmission pipelines, gathering systems, terminal lines, electrical feeds, fiber, water and third-party utilities may occupy the same right-of-way or industrial site. The 811 ticket creates the notification record, but safe execution depends on the field team carrying that information into planning, potholing, operator coordination and stop-work decisions.\n
