## Document text

6.1 Each GDC shall submit annually a proposed rolling 5-year Infrastructure, Safety, and Reliability Plan ("ISR") identifying proposed capital spending necessary to maintain the Reliability and quality of its Natural Gas Distribution Services. The proposed ISR shall be submitted no later than April 30, 2021 or 90 days following the effective date of this regulation, whichever is later, and no later than April 30th every year thereafter. The initial report shall address 2021, and subsequent reports will address the current year in which it is submitted and four subsequent years. The proposed ISR shall be structured under the following major spending categories:

6.1.1 Mandatory

6.1.1.1 New business - Customer requirements

6.1.1.2 Facility relocations

6.1.1.3 Required Statutory and Regulatory Requirements

6.1.1.4 Reliability - emergency failures/system improvements

6.1.1.5 Infrastructure Replacement Programs

6.1.2 Non-Mandatory

6.1.2.1 Supply/Capacity/Load/System Pressure

6.1.2.2 Asset Condition

6.1.2.3 Other Reliability (LNG, regulator station upgrades)

6.2 Mandatory spending shall include investments required to comply with customer requests, facility relocations, statutory and regulatory requirements, to repair failed equipment and for infrastructure replacement programs. The proposed budgets may be for a combination of discrete projects and projects that are funded but whose specific scope has not yet been defined ("blanket projects").

6.3 Non-Mandatory spending shall include projects, programs, or other investments necessary to maintain or improve Natural Gas Distribution Services that are not included in the mandatory spending category. Projects or groups of Related Projects shall be supported with project authorization documents, including detailed cost estimates. Infrastructure replacement and Reliability-based programs shall be supported by guidelines or program documents. The proposed budgets may be for a combination of discrete projects and blanket projects.

6.4 To support each proposed annual budget, the proposed ISR shall describe:

6.4.1 How the GDC developed the spending plan and levels;

6.4.2 The justification, scope, system planning and modeling outputs; and

6.4.3 Estimated cost for each planned project of $1,000,000 or more.

6.5 The proposed ISR shall include the GDC's estimated cost of plant in service and cost of removal for each year of the five-year term.
