For most hydro plant O&M teams, FERC Part 12 audit prep isn't a process — it's a scramble. Maintenance logs live in spreadsheets. Inspection records are scattered across email folders. Spillway PM histories, gate lubrication schedules, and instrumentation drift logs each exist in a different system — or no system at all. When the independent consultant shows up for the five-year periodic inspection, someone spends weeks digging, printing, and organizing evidence that should have been a one-click export. One mid-size run-of-river hydro plant eliminated that scramble entirely. This is how they cut FERC Part 12 audit prep from 18 days of manual effort down to 6 hours — using Oxmaint's pre-built FERC evidence packages and structured compliance workflows.

THE CHALLENGE
Why FERC Part 12 Audit Prep Was Breaking the Team
FERC's 18 CFR Part 12 independent consultant inspection program requires licensed hydropower projects to undergo comprehensive safety assessments on five-year cycles — with formal evidence packages covering dam safety surveillance, instrumentation monitoring, spillway maintenance, gate operation records, and corrective action completion. The regulation is not lenient: findings that go unremediated within FERC's directed timeline create license risk. For this plant, meeting the inspection standard wasn't the problem. Documenting it was.
01
Records Across 4 Disconnected Systems
Gate lubrication logs in Excel. Instrumentation drift readings in a shared drive. Spillway PM records in a paper binder. Corrective actions tracked in email. No single source of truth.
02
18 Elapsed Days of Staff Time Per Cycle
Two senior maintenance staff members spent the equivalent of three and a half work weeks each audit cycle pulling, formatting, verifying, and organizing evidence — time pulled directly from active plant operations.
03
No Audit Trail for Completed Corrective Actions
When the previous cycle's findings had been remediated, records were incomplete. The team knew the work had been done — but couldn't prove it with the timestamped, signed-off evidence an independent consultant requires.
04
Surveillance Gaps Not Caught Until Inspection
Three instrumentation monitoring gaps — missed piezometer readings over a 14-month window — were only discovered during evidence compilation, not when they occurred. The consultant flagged them as a surveillance program weakness.

Is Your Plant Ready for Its Next FERC Periodic Inspection?
Oxmaint's pre-built FERC Part 12 evidence packages, structured surveillance workflows, and one-click audit exports are live for hydro plants today.
THE SOLUTION
How Oxmaint Was Deployed in 3 Weeks
The plant's maintenance coordinator used Oxmaint's hydro-specific asset templates to stand up the system in 21 days — migrating historical records, building the FERC Part 12 surveillance schedule, and configuring the pre-built compliance evidence package. No IT project. No consultant. No 18-month implementation.
Week 1
Asset Structure & Historical Migration
All dam structures, gates, turbines, and instrumentation points mapped into Oxmaint. 3 years of prior maintenance history imported from Excel. FERC project license number linked to asset records.
Week 2
Surveillance Schedule & PM Configuration
Part 12 surveillance program built into Oxmaint PM scheduler — piezometer readings, seepage monitoring, gate operation tests, and spillway condition rounds all auto-generating work orders on required intervals.
Week 3
Evidence Package Configuration & Team Training
FERC Part 12 evidence package template configured — mapping each required documentation category to its Oxmaint data source. Maintenance team trained on mobile work order completion with compliance fields.
THE RESULTS
What Changed When the Next Inspection Arrived
Fourteen months after deployment, the FERC-appointed independent consultant arrived for the periodic inspection. The difference was immediate and measurable.
Audit Evidence Package Generated in 6 Hours
What previously took two staff members 18 elapsed days — pulling records, chasing sign-offs, formatting evidence binders — was generated from Oxmaint in a single morning. One click exported the pre-structured FERC Part 12 package with every required documentation category populated.
0
Findings Issued
The consultant issued zero corrective action findings — the first clean inspection in the project's 12-year licensed history.
100%
Surveillance Coverage Documented
Every scheduled instrumentation reading and surveillance round had a timestamped, technician-signed completion record in Oxmaint.
$0
Overtime Cost for Audit Prep
Prior cycles required $14,000–$18,000 in overtime labor to complete the evidence package on time. The Oxmaint cycle needed none.
"The consultant asked for our gate operation test records for the past five years. I pulled the Oxmaint export in about 90 seconds. He said it was the most complete records package he'd seen from a plant this size."

HOW IT WORKS
Oxmaint's FERC Part 12 Compliance Capabilities
Oxmaint's hydro plant CMMS is built around the documentation categories that FERC Part 12 independent consultant inspections actually require — not generic asset management fields that need to be adapted.

FREQUENTLY ASKED
Hydro Plant FERC Compliance with Oxmaint
What FERC Part 12 records does Oxmaint generate and store?
Oxmaint tracks all standard Part 12 documentation categories: dam surveillance rounds, instrumentation monitoring readings, gate and spillway maintenance records, corrective action completion chains, and emergency action plan drill history. Each record is timestamped and signed off by the completing technician. Learn more at
app.oxmaint.ai.
How long does it take to deploy Oxmaint at a hydro plant?
Most single-structure hydro projects are fully operational in 2–4 weeks. Multi-dam projects with complex asset hierarchies typically complete deployment in 4–6 weeks. Implementation requires no dedicated IT team — the O&M coordinator handles setup with Oxmaint onboarding support.
Can we import our existing Excel maintenance records into Oxmaint?
Yes. Oxmaint supports bulk import of historical work orders and asset records from Excel and CSV formats. Most plants migrate 2–5 years of prior history during the first week of deployment to ensure the audit package covers the full inspection cycle window.
Does Oxmaint work for multi-unit or multi-dam projects?
Yes. Oxmaint's asset hierarchy supports complex hydro project structures — multiple dam structures, powerhouses, unit-level maintenance tracking, and project-level compliance reporting all within a single account.

What does Oxmaint cost for a hydro plant?
Oxmaint is available at accessible subscription pricing built for O&M-scale teams — significantly below the cost of legacy CMMS platforms or custom compliance software.
