Document:
If a new P.G. does not expect to use a physical ink or embossed seal in the P.G.’s professional practice (he or she expects to place an electronically generated seal on all documents that require a seal and physically sign the document), he or she may choose to meet the requirement of submitting a seal to the TBPG by generating an electronic seal and printing it on the appropriate P.G. Seal Submission Form (Form X-PG Seal Submission) in the appropriate place. If a new P.G. does plan to purchase an ink stamp (or an embosser), then the new P.G. should use the ink stamp/embosser to provide the seal to the TBPG on Form X.
A P.G. may use any vendor to produce a physical seal. A vendor who provides this service may be located by online searches. Also, most major office supply chains perform this service.
TBPG recommends that ink seals be purchased in lieu of embossed seals because they are easier to decipher and unlike embossed seals, will be easily visible on a copy made of a sealed document.
The TBPG guidance for use and application of the P.G. Seal states that distributing published geoscientific data to the public does not necessarily require a seal on the work product. What is considered “published geoscientific data”?
What reports must be sealed?
Unless exempted by TOC 1002.252, all geoscientific reports required by municipal or county ordinance, state or federal law, state agency rule, or federal regulation, and all other reports provided to the public must be sealed.
What documents, drawings, etc. within a report must be sealed?
TAC §851.156(l): The Professional Geoscientist shall sign, seal and date the original title sheet or 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. 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.
Must all pages of forms used for reporting information to state agencies be sealed and signed?
In order to comply with TBPG rules, a P.G. must seal in accordance with TAC §851.156 (k) and §851.156 (l) (see the FAQ response above). However, a P.G. must also seal documents in compliance with governmental agency rules, when such are more stringent than TBPG’s rules.
If geology is added to a base map prepared by others must the map be sealed?
Yes. However, it is recommended that the source of the base map be made clear and the additions made clear in a note added to the map in the vicinity of the placement of the seal.
Must boring logs contain a seal and a signature?
Yes, if the boring log is prepared by a Professional Geoscientist.
Can a certification page be used that lists each of the people that were significantly involved in a project along with their areas of responsibility to identify the persons sealing a document?
Do Phase I, II, or III Environmental Site Assessments (ESAs) require a seal?
The American Society for Testing and Materials (ASTM) has published standards for Environmental Site Assessments. Often, reports generated by industry professionals are generated that do not fully meet the definition of ASTM’s guidelines for the type of Environmental Site Assessment (Phase I, II, or III) that the report is labeled to be. For example, a firm may call an environmental site assessment a “limited Phase II ESA.” A Phase II ESA that is completed fully in compliance with ASTM Guidelines does involve an assessment or interpretation of the subsurface (which is the public practice of geoscience). If a report is generated called a “”limited Phase II ESA” and the report is “limited” in that it does not involve an assessment of or the interpretation of the subsurface, then the report would not be required to be sealed.
By the same token, if a report is called a “Phase I ESA,” but the report does involve an assessment of or the interpretation of the subsurface, then the report must be sealed.
In general, all geoscience reports or any other reports containing new or original geoscience must be sealed unless otherwise exempt under Sec. 1002.252 of the Act. Anyone that reports geoscience information taken from the literature should reference the source for any geoscience reported.
Is a license as a Professional Geoscientist required for a Groundwater Conservation District employee to take responsible charge of a groundwater availability report that is required by state law?
