Two federal rules are coming for small gas systems. The clock starts the day the first one is final.

When a PHMSA rule is published, operators typically get 12 to 18 months to comply. That sounds like time. For a system with two people in the gas department, it isn't — and every other small operator in the state is on the same clock.

Day 0
Final rule published in the Federal Register. Effective date set.
Months 1–6
Everyone reads it. Consultants book up. Vendors quote against demand.
Months 6–12
Plans get rewritten. Records get hunted. Equipment gets ordered — and back-ordered.
Months 12–18
Compliance date. Inspectors start asking for what the rule requires.

What's coming

Both rules come out of the PIPES Act of 2020. One is moving through the final stages now. The other was finalized, pulled back before publication, and is still owed under the statute.

Moving — final rule pending

The Distribution Rule

PHMSA's response to the 2018 Merrimack Valley overpressurization. The advisory committee worked through it in May 2026; a final rule is the next step.

What it asks of a distribution operator:

Records for regulator stations and overpressure-protection equipment — attributes documented and available, not "somewhere in a truck."
Updated distribution integrity management (DIMP) content, with PHMSA naming the threats it expects evaluated: cast iron and other piping with known issues, overpressurization of low-pressure systems, and extreme weather and other geohazards — including the effect of age on each.
Procedures for overpressure protection, construction oversight, and emergency-response notification.
Reporting changes that follow the new requirements.

Docket: Safety of Gas Distribution Pipelines and Other Pipeline Safety Initiatives. Advisory bulletin ADB 26-06 on DIMP risk evaluation already issued.

Withdrawn — still mandated

Leak Detection & Repair

Finalized in January 2025, withdrawn from the Federal Register before publication, consistent with the January 20, 2025 regulatory freeze memorandum. The Section 113 mandate remains, so a version of it returns. When it does, it is the largest change to day-to-day gas operations in decades.

What the withdrawn rule required:

Advanced leak detection equipment meeting performance standards — surveys by human senses alone no longer sufficient.
More frequent leak surveys, especially in Class 3 and 4 locations, and surveys extended to valves, meters, regulators, and tie-ins.
Every leak graded 1, 2 or 3, each grade with a mandatory repair clock.
Blowdown emission mitigation, pressure-relief device requirements, and expanded reporting.

Docket PHMSA-2021-0039. Timing of the reissued rule is unknown; the obligations are known.

What happens when a rule goes final

It's the same pattern every time — the transmission integrity rules, the valve rule, the gathering rule. The operators who wait pay more and get less.

Experts book out

There are only so many people in Oklahoma who can write a compliant OQ program or DIMP plan. Twelve months out, they're booked. Six months out, you get whoever is left.

Prices follow demand

Leak-survey equipment, contractor crews, consultant day rates — all of them are quoted against a deadline the seller can see as clearly as you can.

Records don't appear on schedule

The regulator-station records the Distribution Rule wants take field visits to rebuild. That's a season of work, not a week — and it can't be rushed in winter.

The inspector doesn't grade on a curve

A compliance date is a date. "We hired someone in month fourteen" is not a finding the OCC can write down as anything other than a finding.

Get in front of it

Nothing in either rule is a surprise. The proposed text has been public since 2023. Most of the work is the same regardless of the final wording — and it's work you should be doing anyway.

Item	Start now	Wait for the final rule
Regulator-station records	Rebuilt opportunistically on routine visits over the next year. No extra trips.	Dedicated field campaign under deadline, at overtime, in whatever season it lands.
DIMP plan	Reviewed against ADB 26-06 now; the Distribution Rule changes get layered in when final.	Rewritten from scratch against the clock alongside everything else.
Leak survey program	Grading and repair timelines adopted now as practice; equipment evaluated without a deadline.	Equipment ordered into a national backlog; procedures written in a hurry.
OQ covered tasks	Leak-survey and detection tasks added to the program as you go.	Requalification wave for every field employee at once.
Calendar	Every recurring obligation already on one calendar with an owner. New rules add lines, not a system.	Building the calendar and meeting the new deadlines at the same time.

A compliance review now costs less than a compliance scramble later.

We'll go through your system, your plans, and your records against today's rules and the two that are coming, and hand you a written list: what's in place, what's missing, what to do first. Then we keep the calendar so you don't have to.
