Natural Gas Distribution Infrastructure Safety and Modernization (NGDISM) Grant Program
The Natural Gas Distribution Infrastructure Safety and Modernization (NGDISM) Grant Program is a federal funding opportunity administered by the U.S. Department of Transportation. With $98 million available, the program supports efforts to repair, rehabilitate, and replace aging natural gas distribution infrastructure across the country. If your municipality, gas utility, or local government operates leak-prone pipelines or outdated distribution systems, this grant could provide the funding needed to modernize your infrastructure and protect public safety.
What Is the NGDISM Grant Program?
The NGDISM program was established to address the significant safety and environmental risks posed by aging natural gas distribution pipelines. Many communities across the United States rely on gas distribution networks that were installed decades ago using materials now considered leak-prone, such as cast iron and bare steel. These older systems are more susceptible to leaks, corrosion, and failure, posing risks to public safety and contributing to methane emissions.
Through this grant program, the Department of Transportation aims to accelerate the replacement and modernization of these aging systems. The program prioritizes projects that reduce safety hazards, lower methane emissions, and improve the overall reliability of natural gas distribution networks.

Key Program Details
- Federal Agency: U.S. Department of Transportation
- Total Funding Available: $98,000,000
- Award Range: $10,000 to $98,000,000
- Posted Date: March 23, 2026
- Application Deadline: May 22, 2026
The wide award range means this program can support both small-scale pipe replacement projects and large, system-wide modernization efforts. Whether you need to replace a few blocks of cast iron pipe or overhaul an entire distribution network, NGDISM funding may be able to help.
Who Is Eligible to Apply?
The NGDISM Grant Program is designed to serve the entities that own and operate natural gas distribution systems. Eligible applicants typically include:
- Municipal gas utilities: City- or town-owned gas distribution systems
- Local governments and municipalities: Jurisdictions that own or operate gas distribution infrastructure
- Community-owned natural gas distribution companies: Cooperatives and other community-owned utilities
- State and local government entities: State agencies and political subdivisions involved in gas infrastructure
The program is particularly relevant for smaller, publicly owned gas utilities that may lack the capital resources to fund large-scale infrastructure replacement on their own. These systems often serve rural or underserved communities where aging pipelines represent the greatest risk.
What Can the Funding Be Used For?
NGDISM grants support a range of activities focused on improving the safety and reliability of natural gas distribution infrastructure. Eligible uses of funding include:
Replacing Leak-Prone Pipelines
The primary focus of the program is replacing outdated pipeline materials that are prone to leaks and failures. This includes removing and replacing cast iron pipes, bare steel pipes, unprotected steel pipes, and other legacy materials with modern, safer alternatives such as plastic or coated and cathodically protected steel pipe.
Rehabilitating Existing Infrastructure
For systems where full replacement may not be immediately feasible, the program supports rehabilitation work that extends the useful life of existing infrastructure and reduces leak risk. This can include adding cathodic protection, installing pipe linings, and other repair techniques.
Safety Improvements
Funding can be directed toward broader safety improvements to gas distribution systems, including upgrading pressure regulation equipment, installing excess flow valves, improving leak detection capabilities, and enhancing emergency shut-off systems.
Reducing Methane Emissions
Because aging gas infrastructure is a significant source of methane emissions, projects that reduce leaks also deliver environmental benefits. The program supports work that measurably reduces methane emissions from distribution systems, aligning with broader federal climate goals.
Key Dates and Timeline
- Posted: March 23, 2026
- Application Deadline: May 22, 2026
With less than two months between the posting date and the application deadline, applicants should begin preparing their submissions as soon as possible. Gathering the required documentation, developing project budgets, and securing any necessary local matching commitments takes time.
How to Apply
Applications for the NGDISM Grant Program are submitted through Grants.gov. Before you can apply, your organization must be registered on both Grants.gov and SAM.gov. If you have not already completed these registrations, start immediately, as the process can take several weeks. Our SAM.gov registration guide walks through the steps.
To prepare a strong application, consider the following steps:
- Review the full Notice of Funding Opportunity (NOFO): Download and carefully read the complete NOFO from Grants.gov to understand all requirements, evaluation criteria, and submission instructions.
- Assess your infrastructure needs: Conduct a thorough inventory of your gas distribution system to identify the highest-priority segments for replacement or rehabilitation.
- Develop a detailed project plan: Include a clear scope of work, project timeline, estimated costs, and expected safety and environmental outcomes.
- Demonstrate community impact: Quantify the safety risks posed by your current infrastructure and explain how the proposed project will benefit your community.
- Prepare your budget: Provide a detailed budget that clearly shows how NGDISM funds will be used and identify any cost-sharing or matching contributions.
- Gather supporting documentation: Collect relevant permits, engineering assessments, letters of support, and any other materials that strengthen your application.
Tips for a Competitive Application
Given the broad award range and limited total funding, competition for NGDISM grants is expected to be strong. Here are strategies to make your application stand out:
- Prioritize safety impact: Clearly document the safety risks associated with your current infrastructure, including leak history, pipeline age, and material type.
- Quantify environmental benefits: Estimate the methane emission reductions your project will achieve. Data-driven environmental claims strengthen your case.
- Show readiness: Demonstrate that your project is ready to proceed. Applications with completed engineering designs, secured permits, and committed local funding are more competitive.
- Address equity considerations: If your project serves low-income, rural, or historically underserved communities, highlight this in your application.
- Align with federal priorities: Connect your project goals to broader DOT objectives around infrastructure safety, climate action, and equitable service delivery.
