In response to rapid population growth as well as to address the nutrient reduction goals for the Chesapeake Bay established by the Virginia Department of Environmental Quality (VDEQ), the Hampton Roads Sanitation District (HRSD) initiated the York River Treatment Plant (YRTP) Expansion Phase 1 project. The existing YRTP is a conventional step-feed activated sludge plant and is rated for an average daily design flow of 57 million liters per day (MLD). This project proposes to expand the existing treatment capacity to 114 MLD and to reduce the nutrients discharged to the York River, a tributary for the Chesapeake Bay. In order to meet the effluent limits set by the VDEQ, a treatment upgrade to limit of technology (LOT) or enhanced nutrient removal (ENR) was required. Malcolm Pirnie worked with HRSD and the VDEQ to develop and evaluate ENR process alternatives to achieve the required effluent limits with the goal of determining the most reliable and cost effective alternative to achieve the aggressive nutrient reduction goals. This paper will highlight the key issues in determining the most desirable treatment process considering both economic and non-economic factors.

Three Factor

Purpose The purpose of this paper is to compare public preferences for investment and spending on non-automobile infrastructures (mass transit and bicycling) to preferences for new roads and the repair of current highways. The study explores the factors that explain preferences for non-automobile infrastructure using a three-factor model including self-interest (personal transportation benefits), concern for community-wide benefits (political beliefs), and concern for the economic impact. The study uses a case study of the urban context of the Hampton Roads region of Southeastern Virginia (USA). Design/methodology/approach The analysis uses data from a 2013 telephone survey of urban residents in the Hampton Roads area. Survey respondents were asked to identify their two investment priorities from four options: repairing existing roads, bridges, and tunnels; constructing new or expanding roads, bridges, and tunnels; expanding mass transit; and expanding bicycle routes and improving bike safety. Findings Repairing existing highway infrastructure is the most popular spending priority (66 percent of residents). There is as much support (46 percent) for investing in non-automobile infrastructure as for investing in new roads, bridges, and tunnels. Significant predictors of support for non-automobile infrastructure, using the three-factor model, are: length of commute time, self-identification as liberal, use of light rail, and a belief that light rail contributes to economic development. Originality/value The study examines public preferences for both non-traditional and traditional transportation infrastructure investments. It highlights the factors that contribute to public support for different transportation spending options.

The Office of Naval Research recognizing the importance of education, specifically science and mathematics, embarked nearly a decade ago on their National Naval Responsibility for Naval Engineering program. Since then, academia, industry, and SNAME have increased their individual and collaborative efforts towards reaching out to students in an effort to share the excitement and opportunities available within the marine industry. Recently, in this vein, the Northrop Grumman Shipbuilding Apprentice School Chapter of the Hampton Roads SNAME chapter held a “Boat Design Competition” exposing over 240 high school students from 10 school districts (30 teams from 18 different high schools) to the excitement and knowledge needed to prepare design, construction and engineering packages using guidelines, lectures, and tutorial videos prepared by Apprentices and veteran Naval Architects. This was the first time high school students had the opportunity to compete in a head-to-head competition to design, construct, and operate the best boat relative to a number of prescribed requirements. The program also served to educate Apprentices in leadership, project management, research methods, brainstorming, naval architecture and systems engineering as well as establish a nurturing relationship between student chapter and veteran SNAME members which continues today.
