The Oklahoma Conservation Commission (OCC) is required to “[a]dminister the Blue Thumb Program,” Okla. Stat. tit. 27a, § 3-2-106(A)(29), which is a “nonpoint source educational program emphasizing water quality education, including volunteer monitoring[.]”  Okla. Stat. tit. 27a, § 3-1-103(18).


“The primary goal of this program is to educate Oklahoma[ns] . . . about [non-point source] pollution, pollution prevention, and stream health.”  Okla. Admin.

Collection of Information:

Ag-Gag Law:

     6. Enter or remain on an animal facility when the person has notice that entry is forbidden by any of the following:

          a. written or oral communication with the owner or a person with apparent authority to act for the owner,

          b. fencing or other enclosure obviously designed to exclude intruders or contain animals, or

          c. a sign or signs posted on the property or at the entrance to the building” Okla. Stat. tit. 21, § 1680.2.

Trespass Laws:

Criminal Liability for Trespass Despite Lack of Notice:

No.  In order for entry upon property to constitute criminal trespass, such entry must have been “expressly forbidden[,]” or made “without permission by the owner or lawful occupant . . . when such property [was] posted” with signs forbidding entry.  Okla. Stat. tit. 21, § 1835.  “Property that is fenced or not fenced must have such signs placed conspicuously and at all places where entry to the property is normally expected.”  Id.

Other Provisions:

Trespass against “private land of another that is primarily devoted to farming, ranching, or forestry” carries a heightened penalty.  Okla. Stat. tit. 21, § 1835.2.


See supra “Ag-Gag Law.”

Stalking Laws:

“Any person who willfully, maliciously, and repeatedly follows or harasses another person in a manner that:

    1. Would cause a reasonable person or a member of the immediate family of that person as defined in subsection F of this section to feel frightened, intimidated, threatened, harassed, or molested; and

Use of Information:

Although our research is incomplete, these provisions could be construed to allow the use of information collected by citizens.

Explicitly Allows:

“For the purpose of submitting compliance certifications or establishing whether or not a person has violated or is in violation of any provision of the Oklahoma [Clean Air Act] implementation plan, nothing shall preclude the use, including the exclusive use, of any credible evidence or information, relevant to whether a source would have been in compliance with applicable requirements[.]”  Okla. Admin. Code § 252:100-43-6.  “Credible evidence” is not defined.

Explicitly Allows:

OCC manages a volunteer program that monitors nonpoint source water pollution.  See supra “Ongoing Projects.”  Among other things, OCC uses the program to “provide[] support to cities to help meet the requirements of their Phase II stormwater permits[,]” Okla. Admin. Code §155:40-1-5(7), and targets areas “where volunteer data indicate a need.”  Okla. Admin. Code § 155:40-1-5(6).

Evidentiary Standards:

Requires certification that “[t]he allegations and other factual contentions have evidentiary support or, if specifically so identified, are likely to have evidentiary support after a reasonable opportunity for further investigation or discovery.”  Okla. Stat. tit. 12, § 2011.

Authentication or Chain of Custody:

“The requirement of authentication or identification as a condition precedent to admissibility is satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims it to be.”  Okla. Stat. tit. 12, § 2901.
