NAWTEC16-1923 UNIQUE ELEMENTS OF THE OLMSTED COUNTY FACILITY EXPANSION

ABSTRACT Olmsted County is currently expanding their existing waste-toenergy facility in Rochester, Minnesota to add a third mass burn waste combustor. The new unit will have a capacity of 200 TPD, effectively doubling the size of the existing capacity. This paper will discuss some of the unique aspects of this project and review the current status. Some of the interesting and unique features to be discussed include

Curved Steel Bridge Research Project, Interim Report I: Synthesis

DTFH61-93-C-00136The objectives of the FHWA Curved Steel Bridge Program are (1) to conduct fundamental research into the structural behavior of curved steel flexural members and bridges, and (2) to address construction issues, in order to provide adequate information to develop and clarify design specifications. The work under this program is a coordinated effort between the Transportation Research Board (TRB), the Federal Highway Administration (FHWA), and participating States under a Highway Planning and Research (HP&R) Pooled Fund Study. This program focuses on four areas: (1) synthesis of work that has been done since the Consortium of University Research Teams (CURT) Project; (2) update of the current specification in a load factor design format; (3) conduct of research recommended by Structural Stability Research Council's (SSRC's) Task Group 14 at the April 14-15, 1991 workshop; and (4) development of a load and resistance factor design specification based on research conducted area 3. Areas 1 and 3 are conducted by FHWA as a pooled fund study with an administrative contract. Area 2 is conducted by TRB under the National Cooperative Highway Research Program (NCHRP) Project 12-38. Area 4 is proposed to be addressed by NCHRP at a future date. This report summarizes the results of a comprehensive literature search under the FHWA research program

High-tension Cable Median Barrier Safety Effectiveness Evaluation

(c) 1030652The objective of this study was to evaluate the change in crash frequency or severity of varying lateral offset distances of high-tension cable median barriers in Minnesota. Crash and traffic data from 2016 to present were conjoined with roadway cross-sectional data and high-tension cable barrier locations to perform cross-sectional analyses for interstate segments equal to or greater than 0.05-miles long. Negative binomial regression models were estimated and used to develop crash modification factors (CMFs) for the following crash types: total crashes, target crashes, and barrier crashes. In addition to evaluating the impact of lateral offset, a na\uefve before-after evaluation was completed to quantify the impact of installing high-tension cable barrier

Tucannon River Temperature Study, Prepared for : Watershed Resource Inventory Area (WRIA) 35.

This report presents the results of a temperature analysis of the Tucannon River completed for the WRIA 35 Planning Unit. The Tucannon River is located in southeastern Washington and flows approximately 100 kilometers (km) (62 miles) from the Blue Mountains to the Snake River. High water temperature in the Tucannon River has been identified as a limiting factor for salmonid fish habitat (Columbia Conservation District, 2004). Several segments of the Tucannon River are included on Washington State Department of Ecology (Ecology) 303(d) list of impaired waterbodies due to temperature. Ecology is currently conducting scoping for a temperature Total Maximum Daily Load (TMDL) study of the Tucannon River. The WRIA 35 Planning Unit retained HDR Engineering to evaluate water temperature in the Tucannon River. The project objectives are: (1) Review recent and historic data and studies to characterize temperature conditions in the river; (2) Perform field studies and analyses to identify and quantify heating and cooling processes in the river; (3) Develop and calibrate a computer temperature model to determine the sources of heat to the Tucannon River and to predict the temperature of the river that would occur with increased natural riparian shading assuming the current river morphology; (4) Evaluate differences in river temperatures between current and improved riparian shading during the 'critical' period - low river flows and high temperatures; and (5) Determine the potential benefits of riparian shading as a mechanism to decrease river temperature

City of Silverton final wastewater system facility master plan

313 pp. Bookmarks supplied by UO. Includes maps and figures. Published February, 2007. Captured March 19, 2008.Over the past 10 years, the City of Silverton has implemented many improvements to provide quality service to ratepayers and protect the sensitive natural environment that contributes to the area’s scenic beauty. The City planned for and built a state-of-the-art treatment plant that supports beneficial reuse of effluent at the Oregon Garden site. Now, almost a decade after these improvements, the City faces new drivers. These drivers include: an expanding population in this scenic community which maintains a quaint rural character while being close to employment centers in Salem and Portland; new regulatory considerations, including a thermal load limit and waste load allocations included in the pending Molalla-Pudding Total Maximum Daily Load (TMDL); I/I contributions to the wastewater collection system, reducing available capacity for growth; limited capacity for biosolids treatment and storage, and limited options for biosolids final disposal. This Wastewater Facility Master Plan addresses these drivers and balances short- and long-term needs to effectively meet treatment requirements and support future growth while minimizing the impact on ratepayers.

Final Report : Scappoose rail corridor study

171 pp. Maps and figures included. Published October 2002. Received from ODOT January 2, 2007.This study provides a comprehensive review of higlway/rail grade crossing geometric and operational opportunities and constraints. These opportunities and constraints have been developed to address the needs of the City of Scappoose, PNWR, ODOT, and Columbia County. Through a six-month planning process, the community and its transportation service providers have crafted a preferred alternative with specific recommendations for each study grade crossing as well as several local access and circulation improvements. This final report provides the City, PNW, and ODOT with a framework for future reconstruction and development projects as well as a tool with which to leverage grants and other funding sources to complete the necessary infrastructure construction and reconstruction.

Rogue Valley commuter rail project : Final report

55 pp. Bookmarks modified by UO. Maps, tables, illus. Published March, 2007. Captured January 29, 2009.The Rogue Valley Metropolitan Planning Organization (RVMPO) has taken the lead to see if the CORP facilities may be more fully utilized to expand transportation options in the region. The MPO has commissioned a number of studies over the past years, exploring the potential for commuter rail between Central Point and Ashland, a distance of just over 16 miles. The RVMPO requested that this additional study be made to reflect the unavailability of the Oregon Department of Transportation (DOT) cars previously available for the project. In addition, RVMPO wanted basic information that it might use to approach the Federal Transit Administration (FTA) for potential funding under the agency's "Small Starts Program." [From the document
