Evaluating Management Options to Increase Roadside Carbon Sequestration

We estimated the amount of carbon sequestered along Montana Department of Transportation (MDT) roads and tested 3 different highway right-of-way (ROW) management techniques to increase carbon stocks. Using Geographic Information System techniques, the total ROW acreage owned by MDT was found to sequester 75,292 metric tons of carbon per year and to consist mostly of grasslands (70%). From 2016-2018 we tested 3 ROW management techniques to increase carbon stocks- increase mowing height, plant woody shrubs, or add legumes to reclamation seed mixes of disturbed soils - at 3 sites (Three Forks [3F], Bear Canyon [BC], and Bozeman Pass [BP]) along Interstate 90 in southwestern Montana. Soil samples generally averaged 0.75–1.5% soil organic carbon (SOC) at the 3F site, 2.5–4% SOC at the BC site, and 1.5–2.5% SOC at the BP site. Average SOC levels were always lower in 2018 than in 2016. Soil respiration rates were generally highest in June or July at the BC site, averaging ~4 μmol CO2 m-2 second-1. Soil respiration rates were lower at the BC site in November 2016, at the BP site in June 2018, and at the 3F site in July 2018 (all ~2–3 μmol CO2 m-2 s-1). Aboveground biomass carbon estimates generally mirrored belowground SOC estimates. Taken together, our findings suggest that of the three treatments implemented (raised mowing height, shrub planting, and disturbance), minimizing disturbance to soils likely makes the greatest contribution to the medium- and long-term carbon-storage potential of these roadside soils

Cultural Resources Survey of Antiquities Permit Portions of the Orion Refurbishment Project in Midland and Mitchell Counties, Texas

Gray and Pape, Inc., performed an intensive pedestrian cultural resources survey of the Area of Potential Effects of permitted segments of proposed pipeline refurbishment located in Midland and Mitchell Counties, Texas. To date, no federal permitting has been identified for the project. However, approximately 3.2 kilometers (2 miles) of the project area are located on lands owned by the City of Midland and the City of Colorado City, and will be reviewed under the Texas Antiquities Code (Texas Natural Resource Code, Title 9, Chapter 191), Permit number 8677. The area surveyed amounts to approximately 20 hectares (50 acres) of survey corridor, which is considered the Area of Potential Effects. A records and literature review of the project location prior to survey identified two previously recorded archaeological sites and two previously conducted surveys within a 1.6-kilometer (1-mile) radius of the project. Fieldwork was conducted in January and March of 2019. The project required 156-person hours to complete and involved archaeological reconnaissance and shovel testing throughout the entire Area of Potential Effects. A total of 116 shovel tests were excavated along current and previously planned routes, of which 10 were positive for cultural materials. One new previously unrecorded site was identified as a result of survey. Site 41MD58 consists of a low-density surface and buried lithic scatter of a limited number of artifacts and artifact types. The surface of the resource area showed clear disturbance from the adjacent pipeline right-of-way and agricultural activities. A portion of the site was in the process of being disturbed at the time of site delineation by pipeline activities unrelated to the current project consisting of an open trench and associated spoil. Shovel tests within the site showed a lack of integrity primarily as a result of natural and artificial processes resulting in the dispersion of artifacts. The site did not contain temporally or culturally diagnostic artifacts and no artifacts were collected. Nor were any cultural features or historic-age standing resources encountered in the field. Based on the paucity of artifacts, lack of diagnostic materials, and lack of integrity, the site portion located within the Area of Potential Effects is recommended not eligible for State Antiquities Landmark or National Register status. Gray & Pape, Inc. recommends no additional archaeological work for the site or surveyed portions of the project detailed in this report. However, Gray & Pape, Inc. recommends that an unanticipated discoveries plan be put into place in the event that discoveries take place during construction. Gray & Pape, Inc. submitted project records to the Center of Archaeological Studies at Texas State University

Mechanical Scraping and Deep Testing of Three Locations within the Aliana Subdivision in Search of the Kirk’s Point Cemetery, Fort Bend County, Texas

In March 2017, Gray & Pape, Inc., of Houston, Texas, conducted mechanical backhoe scraping and trenching on property adjacent to Oyster Creek within undeveloped areas within the Aliana Subdivision, Fort Bend County, Texas. The backhoe testing was conducted to investigate a total of seven anomalies identified using ground penetrating radar during previous investigations conducted in 2006 and 2007. These seven anomalies contained radar signatures that were consistent with possible human burials and thus were considered to possibly be burials associated with the yet undiscovered location of the Kirk’s Point Cemetery. The anomalies are located within three main locations identified as possible Kirk’s Point 1, Kirk’s Point 2, and Kirk’s Point 3. The Lead Agency for this project is the United States Army Corps of Engineers, Galveston District. The goal of this study was to assist Aliana Development Company, the United States Army Corps of Engineers, the Texas Historical Commission, and the Fort Bend County Historical Commission in determining whether or not intact cultural resources, specifically the potential for human burials, are present within areas proposed for construction, and if so to provide management recommendations for these resources. The investigation was undertaken in accordance with requirements set forth by Section 106 of the National Historic Preservation Act, specifically requirements set forth by 36 CFR 800. 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 was completed through close coordination with the United States Army Corps of Engineers, the Texas Historical Commission, and the Fort Bend County Historical Commission. Work was conducted on private property and thus a Texas Antiquities Code permit was not required prior to conducting fieldwork. Scraping and trenching by means of a mechanical backhoe were conducted at each anomaly location. Soils were found to be consistent with Norwood series loam. These soils along with the field conditions at the time of investigation provided excellent visibility for identifying potential features. However, the investigation produced no indication of human burials or other potentially cultural features. Based on the negative results of the investigation, Gray & Pape, Inc. recommends no further work be required regarding the recorded radar anomalies. Gray & Pape, Inc. recommends that the permitting process with the United States Army Corps of Engineers be updated with this new information and that any remaining cultural resource issues, such as a management plan for potentially eligible Site 41FB306, are addressed prior to these areas being developed

Dangerous Writing: Understanding and Political Economy of Composition

Building on recent work in rhetoric and composition that takes an historical materialist approach, Dangerous Writing outlines a political economic theory of composition. In addition to work by others, Tony Scott also draws from two of his own studies--a classroom ethnography of an upper division writing class that was focused on labor and institutionality, and a qualitative study of the function of textbooks within a writing program. The book connects pedagogical practices in writing classes to their broader political economic contexts, and argues that the power of students\u27 writing is prevented from reaching its potential by pressures within the academy and without that tend to wed higher education with the productive logics of fast-capitalism. Scott argues that the political economy has changed dramatically over the past three decades, and though some scholars have addressed those changes, the field as a whole has not developed an adequately rigorous discussion of what they have meant to our work as teachers, scholars and administrators. The majority of postsecondary students are also already workers in an economy that has become less secure, more hostile to worker\u27s rights, and more unequal in terms of wealth and power. Higher education has been subject to the same economic trends as the larger economy, and universities increasingly operate according to efficiency models that have led to, among other outcomes, increases in the use of contingent teaching labor and a corresponding standardization of curriculums. Within writing programs, pragmatist responses to institutional and economic pressures create contradictions between the appearance and aims of writing education in scholarship and the material practice of teaching and writing in the classroom. Managerial tactics push practices in the field toward more easily commodified and administered pedagogies and away from the immediate, the creative, and the politically meaningful (and perhaps dangerous). While previous work has described the exploitation of contingent labor in writing education, Dangerous Writing connects the problem with specific aspects of scholarship and pedagogical practice. By focusing on the structures of labor and of institutions that enforce those structures, Scott finds teachers and administrators are too easily swept along with the inertia of a hyper-commodified society in which students--especially working class students--are often positioned as commodities, themselves. Dangerous Writing, then, is a critique of how productive labor is shaped in writing programs as much as it is a critique of capitalism. Ultimately, Scott\u27s eye is on the institution and its structures, and it is these that he finds most in need of transformation.https://digitalcommons.usu.edu/usupress_pubs/1165/thumbnail.jp

Evaluating the Potential Effects of Deicing Salts on Roadside Carbon Sequestration

This project sought to document patterns of road deicing salts and the effects of these salts on the amount of carbon being sequestered passively along Montana Department of Transportation roads; it was designed collaboratively with a related roadside project that tested three different highway right-of-way management techniques (mowing height, shrub planting, disturbance) to determine whether they have the capacity to increase soil organic carbon. Our sampling did not reveal elevated salt levels at any of the nine locations sampled at each of the three I-90 sites. The greatest saline concentrations were found at the sample locations farthest from the road. This pattern was consistent across all three sites. The range of soil organic matter (SOM) was broad, from ~1% to >10%. Generally, SOM values were lowest adjacent to the road and highest farthest from the road. We found no or weak evidence of a relationship between our indices of soil salinity and SOM levels, with electrical conductivity, exchangeable calcium, and cation exchange capacity. Results imply that if road deicing salts are altering patterns of roadside SOM and potential carbon sequestration, this effect was not captured by our experimental design, nor did deicing salts appear to have affected roadside vegetation during our most recent sampling effort. Our findings highlight the value of experimentally separating the multiple potentially confounding effects of winter maintenance operations on roadside soils: roads could focus the flow of water, salts, and sands to roadside soils. How these types of mass inputs to roadside soils might influence medium- or long-term carbon dynamics remains an open question, but their fuller characterization and possible flow paths will be essential to clarifying the role of roadside soils in terrestrial soil organic carbon sequestration strategies

Cultural Resources Survey of the Lone Star Express II Pipeline – Loop 3, in Eastland, Comanche, Erath, and Bosque Counties, Texas

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 142.27-kilometer (88.4mile) long Lone Star Express II Pipeline Project – Loop 3, in Eastland, Comanche, Erath, and Bosque Counties, Texas. The lead agency for the project has been identified as the United States Army Corps of Engineers, Fort Worth District (Permit No. SWF-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 3, the total Area of Potential Effects within the permit areas measures approximately 209.9 hectares (518.6 acres). This area encapsulates approximately 52.8 kilometers (32.8 miles) of proposed project alignment. 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. A records and literature review of the project location prior to survey identified 13 previously recorded archaeological sites, four historic markers, five cemeteries, and five previously conducted surveys within a 0.8-kilometer (0.5-mile) radius of Loop 3. Of those, the mapped locations for one recorded archaeological site and three previous surveys intersect the project corridor. An additional three archaeological sites are located within 91 meters (300 feet) of the project’s Areas of Potential Effects. Fieldwork on Loop 3 was conducted in the Spring of 2019 with supplemental survey in August, October, and November of 2019 and required approximately 3,680-person hours to complete. Survey involved archaeological reconnaissance and shovel testing throughout anticipated permit areas within the project corridor. In total, approximately 901 shovel tests were excavated within permit areas, of which four were positive for cultural material. No portions of previously recorded resources: 41ER48, 41ER49, 41ER50, or 41ER56, were re-identified; however, two new previously unrecorded resources, 41BQ358 and 41BQ359, and one isolate, BQ-07-ISO-01, were discovered. The newly recorded resources consist of sparse Prehistoric lithic scatters, consisting mainly of debitage and lacking temporally or culturally diagnostic artifacts. The lone diagnostic artifact, Isolate BQ-07-ISO-01, consists of an Ellis or Godley type projectile point dating to the Late to Transitional Archaic. The resource areas within the pipeline corridor showed clear disturbance from the adjacent pipeline right-of-way. Indications of soil deflation, erosion, and past land modifications such as agriculture or terracing were also observed. Further, Resource 41BQ358 and Isolate BQ-07-ISO-01 are located on very spatially limited topographic settings surrounded by slopes of 30 degrees or greater. The workspace at the location of 41BQ359 has been revised to avoid the site thus removing it from permitting. The workspace where it passes the site will be marked by orange fencing. Shovel test results at nearly all permit areas identified subsoils, cemented soils, or bedrock. Alarm Creek in Erath County, Permit Area Number 65, was targeted for deep testing based on geomorphological data, and field results and discussions with the field archaeologist. Deep test results indicated a lack of deeply buried A horizon soils and showed no potential for deeply buried cultural material or paleosols. No cultural features or historic-age standing resources were encountered in the field. No artifacts were collected as a result of survey. It is the opinion of Gray & Pape Inc. that none of the recorded resources retain the potential to provide significant research value and are thus recommended not eligible for the National Register, under Evaluation Criterion D. In addition, the resources are recommended not eligible for State Antiquities Landmark status. Gray & Pape, Inc. recommends no additional archaeological work for these resources or surveyed portions of the project. However, Gray & Pape, Inc. recommends that an unanticipated discoveries plan be put into place in the event that such discoveries take place during construction

Cultural Resources Intensive Pedestrian Survey within the Dayton Loop Pipeline Project, Harris and Liberty Counties, Texas

Gray & Pape, Inc., of Houston, Texas, conducted an intensive pedestrian cultural resources survey of jurisdictional portions of survey corridor within a proposed pipeline alignment measuring a total of approximately 30 kilometers (18.5 miles) located in Harris and Liberty Counties, Texas. The pipeline route is on privately-owned property; therefore, a Texas Antiquities Permit was not required prior to survey. In total, the surveyed property totals approximately 2.8 hectares (7 acres) which defines the Area of Potential Effects. The goals of the survey were to establish whether or not previously unidentified archaeological resources were located within the project area, also defined as the project’s Area of Potential Effects, and whether the pipeline alignment would affect any previously identified cultural resources. The lead agency for the project has been identified as 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. All fieldwork and reporting activities were completed following 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. Fieldwork took place in March 2019 and required 32 work hours to complete. Field investigation consisted of intensive pedestrian inspection, subsurface shovel testing, photographic documentation, and mapping. A total of 20 shovel tests were excavated, of which none were positive for buried cultural materials. No historic structures were identified as a result of survey. Based on the results of the survey, Gray & Pape, Inc. recommends that no further cultural resources work be required and that the project be cleared to proceed as currently planned
