On 12 October 2017, Horizon Environmental Services, Inc. (Horizon) conducted an intensive cultural resources survey of American Midstream Partners, LP’s (AMP) proposed Ajax UL6-31 Lateral pipeline right-of-way (ROW) located in northeastern Andrews and northwestern Martin counties, Texas (Project Area). The development of the pipeline ROW will be privately funded and will not require any federal permitting or coordination. However, it is located entirely on land owned by the University of Texas (UT Land). As UT Land is considered to be public property, the undertaking falls under the regulations of the Antiquities Code of Texas (ACT). At the request of Venado Environmental, LLC (Venado), Horizon conducted the cultural resources survey of the Project Area on behalf of AMP in compliance with the ACT. The purpose of the survey was to determine if any archeological sites were located within the Project Area and, if any existed, to determine if the project had the potential to have any adverse impacts on sites considered eligible for formal designation as State Antiquities Landmarks (SALs). The cultural resources survey was conducted under Texas Antiquities Committee (TAC) permit number 8193.

The Project Area measures approximately 2.3 miles (3.8 kilometers [km]) long by 100.0 feet (30.5 meters [m]) wide (approximately 27.9 acres). The entire length of the proposed ROW is located on UT Land.

The cultural resources survey of the Project Area resulted in entirely negative findings. No cultural materials were observed on the surface of the Project Area or within any of the 35 excavated shovel tests.

Based on the negative survey results, it is Horizon’s opinion that the construction of the proposed Ajax UL6-31 Lateral Project across UT Land will have no adverse effect on significant cultural resources designated as or considered eligible for designation as SALs. Horizon therefore recommends that AMP be allowed to proceed with the construction of the proposed pipeline relative to the jurisdiction of the ACT.
