|(a) The purpose of the Professional Geoscientist's
seal is to show that professional geoscience services were performed
by a qualified licensed Professional Geoscientist and to identify
the Professional Geoscientist who performed the geoscience services.
(b) The Professional Geoscientist seal shall be of
the design shown in this subsection. Physical seals of two different
sizes will be acceptable: a pocket seal (the size commercially designated
as 1-5/8-inch seal) or desk seal (commercially designated as a two-inch
seal). Computer-applied seals may be of a reduced size provided that
the Professional Geoscientist's full name and license number are clearly
legible. The Professional Geoscientist's name on the seal shall be
the same name on the license certificate issued by the TBPG.
(c) A Professional Geoscientist shall seal only documents
that contain geoscience services performed by or under the Professional
Geoscientist's direct supervision. Upon sealing, the Professional
Geoscientist takes full professional responsibility for geoscience
services that are provided through the sealed document.
(d) It shall be misconduct to knowingly sign or seal
any geoscience document if its use or implementation may endanger
the public health, safety, and welfare.
(e) It shall be unlawful for a license holder whose
license has been revoked, suspended, or has expired to sign or affix
a seal on any document.
(f) All seals utilized by a license holder shall be
capable of leaving a permanent ink or impression on the document.
(g) Electronically conveyed geoscience documents requiring
a seal must contain an electronic seal and electronic signature. Such
seals should conform to the design requirements set forth in this
(1) A Professional Geoscientist must employ reasonable
security measures to make the document unalterable. The Professional
Geoscientist shall maintain the security of his/her electronic seal
and electronic signature. The following methods are allowed:
(A) The Professional Geoscientist may electronically
copy the original hard copy of the document that bears his/her seal,
original signature, and date and transmit this document in a secure
(B) The Professional Geoscientist may create an electronic
seal and electronic signature for use in transmitting geoscientific
documents by making a secure electronic graphic of the Professional
Geoscientist's original seal and signature.
(2) The use of an electronically-generated signature
is not allowed by changing the word processing font from a "normal
text" to a signature/handwriting font.
(A) Shown below is a sample of an unauthorized electronically-generated
signature using the Lucida Handwriting font.
(B) Shown below is a sample of a digital image of a
geoscientist's seal and original signature saved as a digital image
(JPEG Format, for example).
(h) Preprinting of blank forms with a Professional
Geoscientist's seal is prohibited.
(i) Signature reproductions, including but not limited
to, rubber stamps, decals or other replicas, and electronically-generated
signatures shall not be used in lieu of the Professional Geoscientist's
actual signature or a true digital graphic copy of the actual signature.
(j) A Professional Geoscientist shall take reasonable
steps to ensure the security of the Professional Geoscientist's physical
or electronically-generated seals at all times. In the event of loss
of a seal, the Professional Geoscientist will immediately give written
notification of the facts concerning the loss to the Executive Director.
(k) Professional Geoscientists shall affix an unobscured
seal, original signature, and date of signature to the originals of
all documents containing the final version of any geoscience document
as outlined in subsection (l) of this section before such document
is released from their control.
(l) Preliminary documents released from a P.G.'s control
shall identify the purpose of the document, the Professional Geoscientist(s)
of record and the Professional Geoscientist license number(s), and
the release date by placing the following text or similar wording
instead of a seal: "This document is released for the purpose of (Examples:
interim review, mark-up, drafting) under the authority of (Example:
Leslie H. Doe, P.G. 0112) on (date). It is not to be used for (Examples:
construction, bidding, permit) purposes."
(m) The Professional Geoscientist shall sign, seal,
and date the original title sheet or a signature page of geoscience
documents, specifications, details, calculations, or estimates, and
each sheet of maps, drawings, cross sections, or other figures representing
geoscientific services carried out under the supervision of the geoscientist,
regardless of size or binding.
(n) All unbound geoscience documents, including but
not limited to, research reports, opinions, recommendations, evaluations,
addenda, and geoscience software shall bear the Professional Geoscientist's
printed name, date, signature, and the designation "P.G." or other
terms allowed under §1002.251 of the Act, unless the geoscience
service is exempt under §1002.252 of the Texas Occupations Code.
Electronic correspondence of this type shall include an electronic
signature as described in subsection (f) of this section or be followed
by a hard copy containing the Professional Geoscientist's printed
name, date, signature, and the designation "P.G." or other terms allowed
under §1002.251 of the Act.
(o) Geoscience services performed by more than one
Professional Geoscientist shall be sealed in a manner such that all
geoscience can be clearly attributed to the responsible Professional
Geoscientist(s). When sealing plans or documents on which two or more
Professional Geoscientists have worked, the seal of each Professional
Geoscientist shall be placed on the plan or document with a notation
describing the geoscience services done under each Professional Geoscientist's
(p) Licensed employees of the state, its political
subdivisions, or other public entities are responsible for sealing
their original geoscience documents; however, such licensed employees
engaged in review and evaluation for compliance with applicable law
or regulation of documents containing geoscience services submitted
by others, or in the preparation of general planning documents, a
proposal for decision in a contested case or any similar position
statement resulting from a compliance review, need not seal the review
reports, planning documents, proposals for decision, or position statements.
(q) When a Professional Geoscientist elects to use
standards or general guideline specifications, those items shall be
clearly labeled as such, shall bear the identity of the publishing
entity, and shall be:
(1) Individually sealed by the Professional Geoscientist;
(2) Specified on an integral design/title/contents
sheet that bears the Professional Geoscientist's seal, signature,
and date with a statement authorizing its use.
(r) Alteration of a sealed document without proper
notification to the responsible Professional Geoscientist is misconduct
or an offense under the Act.
(s) A license holder is not required to use a seal
for a document for which the license holder is not required to hold
a license under Texas Occupations Code, Chapter 1002.
(t) All geoscience documents released, issued, or submitted
by a licensee shall clearly indicate the Geoscience Firm name and
registration number by which the Professional Geoscientist is employed.
If the Professional Geoscientist is employed by a local, State, or
Federal Government agency or a firm that is exempt from the requirement
of registration under Texas Occupations Code, Chapter 1002, Subchapter
H, then only the name of the agency or firm shall be required.
(u) TBPG also considers a document to meet the sealing
requirement if a reader or user of the document can determine that
the original document is complete and unaltered from that which was
subsequently placed under seal.
