You’ve decided to get your hazardous waste tanks certified. That’s the right call. Here’s what to expect and how you can be ready so the process runs smoothly.
Preparation mostly comes down to access and information. We bring all the testing equipment and documentation tools. Your job is to give us clear access to the tanks and let us know what we’re dealing with.
Before We Arrive: What to Have Ready
Know Your Tanks
Have a list ready that shows:
- How many tanks you have
- Where each one is located (building/area)
- What waste each tank holds
- Approximate size of each tank
- How long each tank has been in use
You don’t need exact technical specs, just enough detail so we know what we’re looking at.
Gather Existing Documentation
If you have any of the following, have them available:
- Previous tank certification reports (if applicable)
- Tank purchase records or installation documentation
- Any CUPA (often the fire department) inspection reports or notices your facility has received
- Maintenance logs or records of any tank repairs
If you don’t have any of these, no problem, we’ll create everything from scratch.
Clear Access
This is the single most important thing. We need to see all sides of each tank, measure anchoring systems, check the secondary containment area, and take photographs. Before we arrive:
- Remove or move any stored materials blocking access to tanks
- Clear the area around each tank so we can walk around it fully
- If tanks are in a confined space, make sure the space is accessible
- Arrange for anyone who needs access credentials (badge, escort) to be available during the visit
The clearer the access, the faster we move through the assessment.

Print this checklist and walk through it before your scheduled visit. It covers everything listed above in a one-page format you can hand to your facility manager or maintenance lead.
What We’ll Be Assessing During the Visit
Here’s what our assessment covers. If you notice any of these items before we arrive, just mention them when we schedule, it helps us plan and may save time.
Seismic Anchoring Systems
This is the most common area where facilities need attention. We check whether tanks are properly bolted or cabled to the floor or structure. We look for:
- Anchor bolts in place and properly tightened
- No visible corrosion or deterioration of anchors
- Correct anchor spacing and configuration per California standards
- Solid attachment to the foundation (no loose or missing bolts)
If your anchors show wear or are loose, mention it. We’ll assess and advise on what needs to be tightened, replaced, or upgraded.
Secondary Containment Condition
Secondary containment is the system designed to catch spills. We assess:
- Protective coating or lining integrity, any cracks, peeling, or bare spots
- Berm or curb structural condition
- Drainage function (cleared of standing water or accumulated debris)
- Capacity (must hold at least the volume of the largest tank)
- Proper slope for drainage if applicable
If you notice water pooling, cracks in concrete, or deteriorated coating, let us know upfront. It helps us understand what attention may be needed.
Tank Condition and Material Integrity
We visually inspect the tank itself for:
- Visible corrosion, rust, or discoloration
- Staining around fittings or seams
- Deteriorated gaskets or seals
- Signs of leaks or seepage
Surface-level corrosion doesn’t always mean failure, but we document it and advise on whether the tank material can safely continue holding the waste.
Material Compatibility
Different tank materials (steel, polyethylene, fiberglass, etc.) are compatible with different waste streams. For example, polyethylene tanks can fail when exposed to certain solvents. We verify that the tank material is appropriate for the hazardous waste it holds.
Piping Systems
If piping runs from or through the tanks, especially if it passes through walls, goes underground, or connects to treatment systems, we assess:
- Condition and material appropriateness
- Whether separate piping certification may be needed
- Proper support and securement
Sometimes piping requires its own certification or inspection separate from the tank itself.
What You Don’t Need to Worry About
We bring everything:
- All testing and measurement equipment
- Digital tools for documentation and photography
- Checklists and forms
- Safety gear if needed
You don’t need to arrange inspections with outside agencies or handle any technical testing yourself. We coordinate with your CUPA if needed. Your job is just to let us in and give us clear access to the tanks.
After the Visit: What Happens Next
Once we complete the assessment, we compile our findings into a comprehensive report. If the tanks meet California standards, the report documents that. If we identify any areas needing attention, we tell you exactly what and what your options are for resolution.
Most facilities certify without major issues. For those that do identify needed attention, we make the path forward clear, no surprises, no ambiguity.

Frequently Asked Questions
Do I need to empty my tanks before the assessment?
No. We assess tanks in their normal operating condition. Emptying tanks is not required and is usually impractical for facilities that are actively using them.
What if I can’t find my original tank specifications?
We can work without them. While manufacturer data sheets and original engineering drawings are helpful, we are able to assess tanks based on field measurements, visual inspection, and material identification. Missing documentation adds some time to the process but does not prevent certification.
Should I fix known issues before the inspection?
If you are aware of obvious problems (cracked containment, missing labels, broken anchoring), addressing them before the visit can streamline the process. But you do not need to fix everything in advance. Part of the assessment is identifying what needs attention.
How far in advance should I schedule the assessment?
As soon as you receive a CUPA notice or know your certification is approaching expiration. We typically schedule site visits within a few weeks, but earlier scheduling gives you more flexibility, especially if corrections are needed before the certification deadline.
