Summary

What it does: S. Res. 673 expresses the Senate’s support for National Safe Digging Month and encourages homeowners and excavators to contact 811 before digging. It passed the Senate by unanimous consent on April 15, 2026, and, as a simple resolution, does not create binding law or funding. Expected impacts therefore flow through awareness and behavior rather than direct mandates. (govinfo.gov)

Signal vs. noise: Because the measure is symbolic, any measured change will likely appear in medium-run safety and reliability indicators (e.g., DIRT root causes, PHMSA excavation-damage metrics), not in immediate economic aggregates. The evidence base indicates that failing to notify 811 remains the leading root cause of damages; raising awareness plausibly targets that high-frequency failure mode.

Economic Effects

Pathways: avoided strike costs; outage/productivity impacts; locating workload and scheduling; insurance/liability risk. Evidence below emphasizes orders of magnitude and causal channels rather than precise fiscal scores, given the resolution’s nonbinding nature.

  • Avoided direct and indirect costs: Excavation-related utility damages impose roughly $30 billion annually in societal costs (repairs, property damage, medical expenses, lost commerce). Campaigns that raise 811 use target the largest single root cause (no locate request), so even modest behavior changes can yield outsized savings. (commongroundalliance.com)
  • Reliability and market productivity: Strikes to electric, gas, telecom, and water/sewer assets create service interruptions that propagate to businesses and households; reducing frequency lowers downtime and mitigates knock-on losses to output. CGA data attribute nearly a quarter of 2024 damages to lack of notification, a changeable behavior via outreach. (dirt.commongroundalliance.com)
  • Operational costs and capacity constraints: Increased 811 contacts during April can raise ticket volume and locating workload, occasionally delaying project starts. CGA analysis of eight centers found excavators had, on average, a 38% chance of being unable to start on time due to incomplete responses—indicating that spikes without capacity planning can create short-run inefficiencies. (dirt.commongroundalliance.com)
  • Public and private budgets: While the resolution adds no appropriations, PHMSA and states already fund one-call/damage-prevention programs; awareness months can shift near-term resource allocation toward outreach and locates. Federal pipeline safety statutes (e.g., 2011 Act) authorize grants for one-call and state damage-prevention programs, framing the longer-run fiscal backdrop. (congress.gov)

Social Effects

Primary channels: injury/fatality risk reduction; community safety; equity across homeowners/small contractors; emergency services load.

  • Safety outcomes: PHMSA’s April 21, 2026 advisory notes over 875 excavation-related pipeline incidents since 2005, resulting in 40 fatalities, 166 serious injuries, and about $322 million in property damage—underscoring the public-safety stakes. Awareness that prompts more 811 notifications can reduce high-severity, low-frequency events. (govinfo.gov)
  • Community resilience: Preventing strikes reduces outages to critical services (e.g., telecom 911 access, heating/cooking gas, water/sewer), buffering vulnerable populations who are disproportionately harmed by service disruptions. (phmsa.dot.gov)
  • Household-level clarity: 811 is free to callers nationwide and routes to state one-call centers; clearer messaging lowers barriers for homeowners and small contractors to engage with the system. (call811.com)

Environmental Effects

Mechanisms: fewer releases of natural gas (methane) and hazardous liquids from third-party excavation damage; lower ancillary spill remediation and ecosystem disruption.

  • Reduced release risk: Excavation damage is a persistent contributor to pipeline incidents; fewer strikes mean fewer unintentional releases with soil/water impacts (liquids) and methane emissions (gas). PHMSA maintains incident datasets that quantify volumes released and causes. (phmsa.dot.gov)
  • GHG context: EPA’s Greenhouse Gas Inventory tracks methane from natural gas systems; preventing distribution-line strikes curbs episodic emissions that add to sector totals. While the resolution itself is not a climate policy, its safety focus aligns with incremental emissions avoidance. (epa.gov)
  • Regulatory alignment: PHMSA’s 2026 advisory explicitly ties Safe Digging Month to preventing excavation damage during infrastructure expansion—framing environmental risk reduction as a co-benefit of stronger damage-prevention practices. (govinfo.gov)

Temporal Analysis

Short-run versus long-run effects, with attention to leading indicators and lags.

  1. Immediate (April–June 2026): Higher public messaging may increase 811 ticket volumes and locator workload, with some projects facing start delays when responses are incomplete. Expect little measurable change in macro indicators this quarter. (dirt.commongroundalliance.com)
  2. Medium term (6–24 months): If awareness persists, expect incremental declines in “no locate request” damages (currently 24.54% of 2024 cases) and associated outage incidents. Monitor CGA’s DIRT dashboard and PHMSA excavation-damage metrics for trend confirmation. (dirt.commongroundalliance.com)
  3. Long term (2–5 years): Sustained improvements in call-before-you-dig compliance can compound into lower social costs and fewer high-severity incidents, with benefits accruing across safety, reliability, and environmental outcomes. Historical estimates place the societal cost baseline near $30 billion/year; even small percentage reductions have large payoffs. (commongroundalliance.com)

Unintended Consequences and Risk Factors

Documented or credible secondary effects to watch, with mitigation levers.

  • Process inefficiencies and waste: Independent analyses highlight systemic inefficiencies in some state 811 implementations, estimating tens of billions in annual waste on top of direct damage costs. Awareness campaigns should be paired with process improvements (e.g., positive response, mapping upgrades) to realize net benefits. (ipcweb.org)
  • Locate accuracy and records quality: Even with 811 contact, some damages stem from inaccurate or incomplete facility records and locator error—reinforcing the need for utility mapping and QA, not just notification volume. (dirt.commongroundalliance.com)
  • Equity of compliance burdens: Small contractors and homeowners may face scheduling delays; clear timelines and self-service online ticketing can reduce friction. Federal/State guidance emphasizes timely locating and coordination. (phmsa.dot.gov)

Assessment (Analytical, not advocacy)

Integrating the evidence on likely net effects.

Overall stance: Neutral-to-modestly favorable. The resolution itself is symbolic and imposes no direct costs, but it plausibly nudges behavior on the dominant root cause of damages (“no locate request”). Expected benefits are concentrated in safety, reliability, and environmental risk mitigation; short-run trade-offs are operational (locating capacity, scheduling). The balance of evidence suggests that pairing awareness with process improvements (timely/accurate locates, positive response, better mapping) maximizes net gains. (congress.gov)
