Named technical authority for your NDT program in Baytown

What 'of record' means when the auditor arrives

A written practice is not a policy document. It is a set of promises about how one specific company qualifies specific people to do specific work, and both SNT-TC-1A and CP-189 anchor those promises to a Level III. Somebody with demonstrated technical competence in the method has to decide what the training covers, what the examinations ask, what a passing practical looks like, and whether a procedure is fit for the material and geometry it will be used on. When that person is named, currently certified and reachable, the practice holds together. When the name is a formality, everything downstream of it is unsupported.

The failure is rarely dramatic. A contractor buys a written practice template, has a Level III sign the cover page during mobilization, then runs for four years while that Level III retires, lets a method lapse, or moves to a competitor. Certificates issued in year three cite an approval authority that no longer existed in the form the practice claims. An owner's contractor audit finds it in twenty minutes by laying certificate issue dates alongside the Level III's own certification expiry, and the finding is not a paperwork nit — it puts the qualification of every technician on that job in question.

A Level III of record engagement is aimed at the continuity problem specifically. The same certified individual stays attached to your practice, reviews procedures when a code edition changes or the work changes, prepares and grades examinations, and appears — in person or on the call — when a client audits you. The deliverable is not a document. It is a defensible chain from the code, through the practice, through the procedure, to the technician who put the probe on the steel.

Baytown's industrial base and who is actually auditing you

Baytown is not a generic Gulf Coast town with a plant in it. The ExxonMobil Baytown complex is one of the largest integrated refining and petrochemical sites in the United States, combining refinery, olefins and chemical operations on the Houston Ship Channel, with announced low-carbon hydrogen and advanced recycling investment on top of it. Chevron Phillips Chemical runs the Cedar Bayou plant. Covestro operates the Baytown Industrial Park producing polyurethane and polycarbonate feedstocks. JSW Steel USA runs a plate and pipe mill in Baytown. Around all of that sits a dense band of tank terminals, barge docks, machine shops and fabrication yards that live or die on channel turnaround work.

That mix decides what your NDT program has to survive. Owner contractor-qualification audits along the channel routinely ask for the written practice, a sample of technician files, the procedure that produced a specific report, and evidence that the person who approved that procedure was qualified to. Because these are covered processes, mechanical integrity under OSHA 29 CFR 1910.119(j) drags NDT into the PSM audit trail: inspection and testing has to follow recognized and generally accepted good engineering practice, and the NDT procedure is where that claim is made concrete.

There is a second, less-discussed regulator. Texas is an NRC Agreement State, so industrial radiography licensing sits with the Texas Department of State Health Services rather than the NRC, under 25 TAC Chapter 289. That license carries radiographer certification, RSO, utilization log and survey obligations that interlock with your written practice — the same technician file has to satisfy both the state license conditions and SNT-TC-1A. Programs written in another state and dropped into Baytown are the ones that get caught.

What the written practice must actually say

Most practices fail on specificity rather than length. The practice must name the methods and, within those methods, the techniques you perform — not "UT" but straight beam thickness, angle beam weld examination, corrosion mapping, high-temperature scanning. It must state the education, training and experience combinations you will accept, the examination structure and passing criteria, the vision requirements and frequency, the recertification interval, and the treatment of interrupted service. It must identify the Level III by name and by certification, and it must state which edition of SNT-TC-1A or CP-189 it implements.

The edition question is the one that quietly bites. ASME Section V Article 1 points personnel qualification at SNT-TC-1A or CP-189, and a purchase order or owner specification will frequently invoke a specific edition. A practice implementing the 2016 edition while the customer specification calls out 2020 is not automatically wrong, but somebody has to have reconciled the two and written down the reconciliation. Nobody ever has. The Level III of record's first pass usually produces this document before anything else.

The other frequent gap is CP-189 versus SNT-TC-1A confusion. SNT-TC-1A is a recommended practice — it gives you guidelines you tailor in your own written practice. CP-189 is a requirements standard: its criteria are mandatory and it requires the Level III to hold ASNT Level III certification. Companies write "in accordance with SNT-TC-1A and CP-189" into a title block without noticing they have just bound themselves to the stricter of the two on every clause.

Certification arithmetic that fails audits

Examination scoring is where files come apart. The common structure is a general, a specific and a practical examination, each of which must reach a minimum, with a composite that must reach a higher minimum. Take a candidate scoring 88 general, 76 specific and 72 practical: every individual score clears a 70 percent floor, but the composite is 78.7 — below an 80 percent composite requirement. Files get signed on the strength of "all three passed" more often than anyone admits, and a composite recalculated by an auditor is the fastest way to invalidate a certificate.

Training hours and experience are the second arithmetic trap. The recommended hours in SNT-TC-1A are indexed to the candidate's education, and the common error is applying the row for a graduate engineer to a candidate whose degree is unrelated, or applying the high-school row to someone with two years of engineering technology and quietly awarding credit twice. Experience hours must be in the method and documented; time on site in a different method does not count, and hours from a previous employer need substantiation, not assertion.

Vision records are the cheapest finding an auditor can write. Near-vision acuity on a Jaeger #2 or equivalent chart at not less than twelve inches, checked at the interval the practice specifies, plus color-contrast differentiation where the method demands it. The document must show the chart used, the distance, the examiner and the date. A photocopied optician's note that says "vision satisfactory" satisfies nothing, and it is on file in more companies than not.

Procedure approval as a continuing duty, not a one-time signature

A signature on a procedure is a technical claim: that this technique, at this sensitivity, on this material and thickness range, will find what the job needs found. That claim expires when any of the inputs move. A new circuit runs hotter. A customer changes from ASME Section VIII to a client specification with tighter acceptance. The shop buys a different instrument and the old linearity records no longer apply. A weld configuration appears that the procedure's coverage sketch never contemplated.

In practice, the procedures needing the most attention in Baytown are the ones written for one turnaround and then reused for a decade. Corrosion-under-insulation scopes, injection point and deadleg circuits under API 570, and tank shell and critical zone work under API 653 all accumulate technique decisions that were made verbally on a job and never written down: where the scan grid starts, how many readings define a CML, what happens when the backwall is lost, who decides to re-scan. The Level III's continuing duty is to force those into the document.

There is also a coverage question that only a Level III will ask. If the procedure produces a thickness value at a corrosion monitoring location, what fraction of the circuit is actually interrogated, and does the damage mechanism produce localized loss that a spot grid will step over? That is a technical question with a corrosion-rate consequence, and it belongs in the procedure — not in an engineer's head.

Where the Level III stops

Atlantis supplies NDT technical authority. It does not act as your API 510, 570 or 653 inspector of record, it does not sign in-service inspections, and it is not a PSM auditor. Those are separate roles with separate accountability, and any consultant who blurs them is creating a problem for you rather than solving one.

The distinction that matters on a Baytown unit is a three-way one, and it is conflated constantly. The API 510, 570 or 653 inspector authorizes and signs the in-service inspection, and owns the judgment about continued service. The NDT technician is certified under the employer's written practice, to SNT-TC-1A or CP-189, to acquire data using a specified method and technique. The ASNT Level III approves the procedure that technician works to, and the practice under which the technician was certified. Three roles, three sets of evidence, three different failure modes.

Within its boundary the scope is broad: written practice authorship and revision, procedure development and qualification, personnel training, examination and certification recommendation, technical representation during client and regulatory audits, and independent review of inspection data where a report needs a second set of eyes before it goes to an owner.

Outside agency versus a staff Level III

A staff Level III makes sense when volume justifies it — a company running several methods across multiple crews every week, with enough procedure churn to keep the person occupied. Below that, a full-time Level III is an expensive way to buy signatures, and the role degrades into administration while the technical judgment goes stale for lack of exposure.

The outside-agency route trades presence for currency. A consulting Level III who reviews procedures for a dozen operators sees more failure modes in a quarter than a staff Level III sees in three years, and carries the audit experience of every one of them into your program. The risk to manage is the opposite one: an outside Level III who has never seen your equipment, never met your technicians and cannot describe your scope is a liability in an audit room. Continuity, site familiarity and availability are the things to contract for, not headcount.

A hybrid arrangement works well for growing contractors. The outside Level III of record carries the methods where you lack in-house depth while your own Level II staff develop toward Level III examination in the method you run most. The written practice is drafted so the transition changes a name, not a structure.

What an engagement looks like

The first stage is a review, not a rewrite. Atlantis reads your existing written practice, procedures, technician files and the customer specifications that bind you, then returns a gap list organized by risk: findings that would invalidate certificates, findings that would fail a contractor audit, and housekeeping. Companies routinely discover that the fixable problems are in the record-keeping rather than in the technical work their crews actually do.

The second stage is remediation and adoption. Practice reconciled to the edition your customers invoke; procedures revised or written where they do not exist; examination material prepared; technicians re-examined where the record cannot be defended; vision and experience records reconstructed with evidence rather than assertion. Where a procedure needs a qualification demonstration, that is scheduled and documented rather than asserted.

The third stage is the standing relationship: named in the practice, available for procedure approvals and technical questions, present for audits, and reviewing the program on a fixed cycle so the code edition and the customer specifications never drift away from what you actually do.
