PURPOSE: This rule describes the format for the personal seal of a registered geologist and explains in detail where and how the seal shall be used.

1. (1) Each registered geologist shall, at his/her own expense, secure a seal or rubber stamp, one and three-quarters inches (1 3/4") in diameter. The seal shall consist of concentric circles between which shall appear in capital letters “STATE OF MISSOURI” on the upper part of the seal, and “REGISTERED GEOLOGIST” on the lower part of the seal. Within the inner circle of the seal shall appear the name of the registered geologist in printed letters and his/her certificate number preceded by the capital letters “RG.”
2. (2) The seal may be in the form of an embossing seal, a rubber stamp, or a computer-generated image, identical in size or design and content with the provisions of section (1) of this rule.

3. (3) In addition to the personal seal, the registered geologist shall also affix his/her signature on or through his/her seal, and place the date of the signature under the seal on each sheet in a set of plans, drawings, specifications, maps, reports, and other documents which are prepared by the registered geologist or under the registered geologist’s immediate personal supervision.

   1. (A) When there are multiple page plans, reports, maps, drawings, or other documents or instruments, the registered geologist may sign, seal, and date only the title or index page, providing the signed sheet clearly identifies all of the other pages comprising the bound volume were prepared by him/her or under their immediate personal supervision.
   2. (B) When revisions are made, the registered geologist who made the revisions or under whose personal supervision the revisions were made shall place his/her signature on the same line next to the revision date and give an explanation of the revisions.
   3. (C) If a set of multiple page plans, reports, maps, drawings, or other documents or instruments (“documents”) contains the seals of more than one (1) licensed or registered professional, the registered geologist should certify, on the title or index page, that his/her seal only relates to the portions of the documents that involve the practice of geology, as defined in section 256.453(7), RSMo. The registered geologist should identify, on the title page or index, the geologic portions of the documents that he/she, or someone under his/her immediate personal supervision, prepared. The registered geologist may identify those portions of the documents that neither he/ she nor someone under the registered geologist’s immediate personal supervision prepared.
4. (4) If two (2) or more registered geologists provide reports, plans, drawings, maps, or other documents, each registrant shall date, sign and seal those documents using the appropriate disclaimer identifying each registrant’s responsibility.
5. (5) Any documents not prepared by the registered geologist or under his/her personal supervision shall not be signed or sealed by the registered geologist.
6. (6) Any registered geologist who does not have a current license in this state is prohibited from using his/her seal on any documents until the license is renewed or otherwise reinstated.
