Texas Historical Commission
Gray & Pape, Inc. was contracted to conduct a cultural resources survey for a proposed pipeline project. The project is a 14-inch pipeline from Praxair Freeport Plant to the Phillips 66 Clemens Storage Cavern located near Freeport, Texas. The project route measures approximately 28.0 kilometers (17.4 miles). The project’s Area of Potential Effect is the entire alignment route within a survey corridor of 91.4 meters (300 feet). This amounts to approximately 252 hectares (622 acres). Subsequent workspace revisions resulted in an additional 25.7 hectares (63.4 acres) or 2.6 kilometers (1.6 miles) of workspace, documented in Appendix C of this final report. The pipeline will be collocated with several existing pipelines in a well-maintained corridor for the entire length. The Project is part of a Nationwide 12 permit for which the Lead Federal Agency is the United States Army Corps of Engineers, Galveston District. The procedures to be followed by the United States Army Corps of Engineers to fulfill the requirements set forth in the National Historic Preservation Act, other applicable historic preservation laws, and Presidential directives as they relate to the regulatory program of the United States Army Corps of Engineers (33 CFR Parts 320-334) are articulated in the Regulatory Program of the United States Army Corps of Engineers, Part 325 -Processing of Department of the Army Permits, Appendix C -Procedures for the Protection of Historic Properties. Approximately 3.6 kilometers (2.25 miles) of the project length is located within property owned by the Texas Department of Criminal Justice, Clemens Prison Unit, which necessitated the procurement of a permit subject to the Antiquities Code of Texas. Permit Number 8666 was assigned to the project on December 4, 2018. As required under the provisions of Texas Antiquities Code Permit, all project records are housed at the Center for Archaeological Studies at Texas State University, San Marcos, Texas.
The goals of this study were to assist the client, the Texas Historical Commission, and other relevant agencies in determining whether intact cultural resources were present within areas planned for construction, and if so to provide management recommendations for these resources. All work conducted by Gray & Pape, Inc. followed accepted guidelines and standards set forth by the Texas Historical Commission and the Council of Texas Archeologists. Prior to field investigation, site file research was used to develop a cultural context for the study. This research resulted in a listing of all archaeological sites and National Register properties within 1.6 kilometers (1 mile) of the project area, as well as a discussion of archaeological potential within the tract.
Previous surveys conducted by HRA Gray & Pape, LLC and other firms overlap approximately 6.1 kilometers (3.8 miles) / 55.4 hectares (137 acres) of the current project’s corridor. These surveys were undertaken from between 2012 to 2013. These areas along with an additional 2.8 kilometers (2 miles) / 28.9 hectares (71.3 acres) of highly disturbed pipeline corridor were subjected to visual reconnaissance survey only. Another 3.0 kilometers (1.9 miles) / 27.5 hectares (68 acres) of the project is located within highly industrial areas of DOW property and was subjected to desktop assessment and determined to be of low potential for containing intact cultural materials. No further work is recommended for these areas. No new cultural resources were discovered during the survey. Gray & Pape, Inc. recommends no survey within these portions due to the highly disturbed conditions. Intensive pedestrian survey was completed on those portions of the current project that fall outside of the previous survey coverage or that have potential to impact previously unidentified sites. This amounts to 15.6 kilometers (9.7 miles) / 140 hectares (346 acres). As a result of survey efforts, one previously unrecorded archaeological site was identified during survey efforts. As currently mapped, the site is overlapped by an existing pipeline corridor and does not retain integrity within the project right-of-way. Gray & Pape, Inc. recommends that no further investigation be necessary within the surveyed portions of the project.
