Louisiana Geologist seal requirements: proper sizing, signing and sealing of documents
As of
Louisiana licenses geoscientists rather than geologists, so a geologist practising publicly here holds a Professional Geoscientist licence from the Louisiana Board of Professional Geoscientists. R.S. 37:711.22(A) requires a seal of a design established by the board bearing the license holder's name, the license number, and the words "licensed geoscientist" or "professional geoscientist" — the statute offers those two wordings as alternatives. No diameter is set by statute or by LAC 46:LXII.1501; the board issues its approved seal design to the licensee on licensure.
The 1½-to-2-inch range quoted for Louisiana matches no provision of §2701; the rule gives two discrete sizes, 1-5/8 inch and 2 inch. The endorsement legend at §2701.A.2.a.v was added by the April 2025 amendment, LR 51:553. The board is placed in the Office of the Governor and was created by Acts 2010, No. 974, effective January 1, 2011. LAC 46:LXII.1501 was promulgated at LR 41:2348 (November 2015) and amended at LR 45:1469 (October 2019); the current text was read in the state-certified LAC compilation of Title 46, Part LXII published by the Division of Administration, Office of the State Register. The board also publishes a "Louisiana Professional Geoscientist Seal Use Policy" that adds placement guidance — seal on the signature page directly behind the cover for multi-page reports, on the right side across from the signature in a letter, on each page for individually submitted maps and logs — and states that the seal must follow the board's template with the licensee's name at the top and the license number at the bottom. That document is board policy supplementing LAC 46:LXII.1501, not a promulgated rule.

Louisiana Geologist seal
- Seal requirements
- R.S. 37:711.22 (Seal); LAC 46:LXII.1501 (Use of Seals)
- Legend (any one)
- “licensed geoscientist” · “professional geoscientist”
- Diameter
- No diameter is prescribed. R.S. 37:711.22(A) fixes the seal's three elements but states no dimension, and LAC 46:LXII.1501, the rule the statute delegates to, governs only seal possession, responsibility, use and electronic transmission — it prescribes no size and reproduces no design.
- Expiration date
- R.S. 37:711.22(A) lists exactly three elements — name, license number and the prescribed words — and LAC 46:LXII.1501 adds no seal contents at all. Nothing puts an expiry date on the seal.(R.S. 37:711.22(A); LAC 46:LXII.1501)
- Signature date
- A licensee shall affix an unobscured seal, original signature, and date of signature to the original documents in the final version of any geoscience document; seal, signature and date together constitute the certification.(LAC 46:LXII.1501.B.2.a, B.3.a)
- City on seal
- The statute's element list is name, license number and the prescribed words; no place of business or parish appears.(R.S. 37:711.22(A))
- Upon issuance of a license, the license holder shall obtain a seal of a design established by the board bearing: (1) the license holder's name; (2) the license number; (3) the words "licensed geoscientist" or "professional geoscientist".(R.S. 37:711.22(A))
- A geoscientific report, document, or other record, as defined by the board, that is offered to the public and prepared or issued by or under the supervision of a licensed geoscientist must include the full name, signature, and license number of the license holder who prepared it or under whose supervision it was prepared, and bear an impression of the license holder's seal.(R.S. 37:711.22(B))
- Each professional geoscientist, upon licensure, shall obtain an official seal.(LAC 46:LXII.1501.B.1.a)

- A licensee shall affix an unobscured seal, original signature, and date of signature to the original documents contained in the final version of any geoscience document. Each sheet of maps, cross sections, drawings, descriptions, charts, graphs, reports, documents or other records of geoscientific practice shall be signed, sealed, and dated by the licensee who prepares it, supervises its preparation, or reviews it in sufficient depth to fully coordinate and assume responsibility for it.(LAC 46:LXII.1501.B.3.a.i)
- Where multiple sheets are bound together in one volume representing a singular geoscience document, the responsible licensee shall sign, seal, and date a sheet that clearly identifies all of the other sheets included as part of the bound volume.(LAC 46:LXII.1501.B.3.a.ii)
- The rule defines what counts as a geoscientific report requiring the seal, including cross sections displaying geoscience data, contoured drawings such as potentiometric surface and isopleth maps, aquifer test analyses, groundwater modeling, geoscientific components of groundwater management plans, soil boring logs and well logs, soil, lithology and geophysical maps, interpretation of geophysical surveys, and interpretations, conclusions and recommendations based on those data.(LAC 46:LXII.1501.B.3.b)
- Preliminary or draft documents do not require a PG stamp; however, each sheet or page of a preliminary or draft document shall be clearly and prominently marked "preliminary" or "draft".(LAC 46:LXII.1501.B.3.c)
- Phase I environmental site assessments do not require a PG stamp unless one or more geoscientific documents, findings, or conclusions is incorporated into the Phase I ESA; Phase II and Phase III ESAs require a PG stamp.(LAC 46:LXII.1501.B.3.d)
- Documents which require a seal may be transmitted electronically provided the seal, signature and date of the licensee are transmitted in a secure mode that precludes them being produced or modified.(LAC 46:LXII.1501.B.4.a)

This document should not be considered a certified document."(LAC 46:LXII.1501.B.4.b)
Louisiana geologist seal questions
Does Louisiana license "professional geologists"?▾
No. Louisiana licenses professional geoscientists under the Louisiana Professional Geoscience Practice Act, and the seal statute prescribes the words "licensed geoscientist" or "professional geoscientist" — not "geologist". Geology is treated as a discipline within geoscience, and the qualifying examination is the ASBOG fundamentals and practice of geology exam. (R.S. 37:711.1; R.S. 37:711.22(A)(3); LAC 46:LXII.301 (definitions))
Which of the two statutory wordings goes on a Louisiana seal?▾
R.S. 37:711.22(A)(3) permits either "licensed geoscientist" or "professional geoscientist", but the same subsection requires a design established by the board — so the choice is exercised by the board's approved template, which it supplies to the licensee upon licensure, not freely by the licensee. (R.S. 37:711.22(A))
Does a Phase I environmental site assessment need a Louisiana PG stamp?▾
Not by itself. Phase I ESAs are exempt unless one or more geoscientific documents, findings or conclusions is incorporated into them; Phase II and Phase III ESAs always require the stamp. (LAC 46:LXII.1501.B.3.d)
Is one seal on the cover of a Louisiana report enough?▾
For a bound volume, yes — but only on a sheet that clearly identifies all of the other sheets included in the volume. Loose maps, cross sections, charts, logs and drawings submitted individually must each be signed, sealed and dated. (LAC 46:LXII.1501.B.3.a.i-ii)
