Gray & Pape, Inc., of Houston, Texas, on behalf of Lone Star NGL Pipeline, LP, conducted an intensive pedestrian cultural resources survey within permitted areas of the 174.36-kilometer (108.34-mile) long Lone Star Express II Pipeline Project – Loop 1, in Midland, Martin, Howard, Mitchell, and Nolan Counties, Texas. The lead agency for the project has been identified as the United States Army Corps of Engineers, Fort Worth District (Permit No. SWG-2019-00091). Thus, survey efforts concentrated on areas anticipated to be under the jurisdiction of the United States Army Corps of Engineers (permit areas). Within Loop 1, the total Area of Potential Effects within the permit areas measures approximately 125.6 hectares (310.3 acres). This area encapsulates approximately 29.6 kilometers (18.4 miles) of proposed project alignment. In addition, approximately 2.3 kilometers (1.4 miles) or 8.9 hectares (21.9 acres) of the proposed route are controlled by the City of Colorado City and thus required the issuance of a Texas Antiquities Code Permit. Permit number 8896 was issued for the project. 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.
All fieldwork and reporting activities were completed according to a scope of work submitted to the United States Army Corps of Engineers and the Texas Historical Commission and accepted standards set forth by the Texas Historical Commission and the Council of Texas Archeologists and in accordance with Section 106 of the National Historic Preservation Act. Gray & Pape, Inc. submitted project records to the Center of Archaeological Studies at Texas State University.
A records and literature review of the project location prior to survey identified 62 previously recorded archaeological resources, one cemetery, one historic marker, and 22 previously conducted surveys within a 0.8-kilometer (0.5-mile) radius of the Loop 1 segment. Of those, 10 recorded archaeological resources and six previous surveys intersect anticipated permit areas. Fieldwork on Loop 1 was conducted in the Spring of 2019 with supplemental survey in July, August, and September 2019. Survey of Loop 1 required approximately 1,200 Gray & Pape, Inc. person-hours to complete and involved archaeological reconnaissance and shovel testing throughout anticipated permit areas within the project corridor. In total, approximately 664 shovel tests were excavated within permit areas, 25 of which were positive for cultural materials. An additional 122 shovel tests were conducted as part of resource delineation efforts. Field effort also included the excavation of a total of 13 deep tests.
Nine previously recorded resources: 41NL6, 41NL313, 41NL314, 41NL315, 41NL316, 41NL320, 41NL321, 41NL323, and 41NL326; eight new previously unrecorded resources: 41HW142, 41MH128, 41MH130, 41NL377, 41NL378, 41NL379, 41NL380, and 41NL392; and four isolate finds were identified within Loop 1 permit areas. An additional 10 previously recorded resources: 41MD41, 41HW8, 41HW104, 41HW105, 41HW106, 41NL310, 41NL312, 41NL322, 41NL324, and 41NL325; and one newly identified resource, 41MH129, were identified within the Area of Potential Effects but outside of jurisdictional areas. These sites largely exhibited surface scatters of lithics which are typical for the area and were consistent with the resources identified within jurisdictional permit areas.
