Contamination Problem

ABSTRACT Numerous above-ground and underground oil storage tanks and underground piping present a significant groundwater pollution threat when breached or deteriorated. The principal aid in cleaning up a spill on land or at sea is being able to observe it, and this opportunity is lacking in the case of the groundwater incident. A groundwater incident can be equally as damaging to the environment as a surface spill and can directly impact the public health by contaminating drinking water or creating hazardous atmospheres in cellars, storm drains, and sewers. In March 1991, when oil was found leaching from the bank of a river trench leading to the Cape Fear River, the Coast Guard Marine Safety Office (MSO) in Wilmington was able to control the oil in the trench through traditional use of booms and sorbents. The MSO was confronted with the threat of oil contaminating ground water and the challenge of locating the source. This report outlines the decisions, actions, and events surrounding the response to the groundwater contamination problem at the City Gas and Transmission facilty.

Abstract Mahanagar Gas Limited is a City Gas distribution (CGD) company based out of the city of Mumbai and around. MGL currently has around 480 Kms of Steel gas pipelines for transportation of natural gas. The diameters of these pipelines are ranging from 2” to 18” and almost all are coated with 3 layer Poly Ethylene coating (3LPE). We are installing Permanent Cathodic Protection (PCP) for all commissioned pipelines and Temporary Cathodic Protection (TCP) having a design life of 5 years for un-commissioned pipelines during the projects stage itself. This paper shall basically outline the CP system in MGL along with various practices being followed in MGL to ascertain the effectiveness of CP. MGL has installed various CP assets like CP stations, Diode stations, external ER probes, corrosion coupons to ascertain the CP effectiveness. This paper shall outline the detailed monitoring procedure along with monitoring frequency of all the assets. MGL is also carrying out health adequacy surveys like DCVG, CIPL etc over the steel pipeline network. Few case studies arising out of these monitoring results shall be presented in this paper. (1) Casing carrier short at Taloja Railway crossing. The detailed procedure of monitoring and rectification shall be presented. (2) Case study on CP under-protection at Andheri which was resolved using a flange isolation kit.

Learning outcomes This case study focuses on the problems that a company have in segmenting a local market of a gas distribution company and some strategies that they can use for developing a viable market segmentation to target the right segment that will provide a good economics, revenue base customers who also have the mindset to change to a new product. At the end of this exercise, students should have a clear understanding of the following: the essentials concepts of market segmentation, targeting and positioning and how they can be leveraged so that businesses increase their returns; the main elements/steps that drive market segmentation and business positioning; the appropriate methods for market segmentation when targeting local markets for a city gas project; and the challenges companies might face when changing a product. Case overview/synopsis In 2018, commercial customers began asking Abu Dhabi National Oil Company (ADNOC) Distribution to provide a sustainable solution to ensure a continuous supply of safe gas and avoid the interruptions and hazards associated with the supply of liquefied petroleum gas (LPG) to their premises. The request was discussed with the ADNOC marketing, supply and trading (MST) Division to investigate the possibility of growing the natural gas business in the Emirate of Abu Dhabi, thus contributing to the Emirate’s security, economy, environment and community, and ultimately to ADNOC Strategy 2030. Khaled Salmeen, Director of the ADNOC MST Division, believed that industrial customers accounted for higher business volume and profitability. Nevertheless, he advised Shuhab Al Shehhi, the City Gas Project Manager, to study the potential benefits in targeting both residential and commercial customers as part of ADNOC’s responsibility towards community engagement and investments. Al Shehhi had to address several questions: How could the City Gas Project be strategized and positioned so as to target all market segments? What were the potential outcomes? Would targeting all market segments strengthen ADNOC’s brand position?

The fire incident in karaoke buildings in Indonesia which claimed many lives has occurred several times. According to the National Academy of Science US, the smoke toxins that come out of the fire disaster cause 50-80% of deaths. Refers to the data, it is necessary to check further about the building material response to fire during a fire incident. Masterpiece Signature Karaoke is a karaoke building that classified as large and magnificent in the city of Medan which has various material so that it is necessary to study the interior material as passive fire protection. The purpose is to find out how to assess the reliability of fire passive protection regard to the interior materials and recommendations or descriptions of right interior material planning using the Analytical Hierarchy Process (AHP). This method is efficacious to solve the problem of reliability in using interior materials as passive fire protection in Masterpiece Signature Family KTV Medan building with the results of an Adequate Level of reliability. Then, design recommendations were given for the use of interior materials in karaoke building to improve the reliability results to be better.The results are useful as information for other researchers and karaoke buildings regarding passive fire protection systems at the Masterpiece Signature Family KTV Medan.

As destination of choice for many short-term study abroad programs, Berlin offers students of German language, culture and history a number of sites richly layered with significance. The complexities of these sites and the competing narratives that surround them are difficult for students to grasp in a condensed period of time. Using approaches from the spatial humanities, this article offers a case study for enhancing student learning through the creation of digital maps and itineraries in a campus-based course for subsequent use during a three-week program in Berlin. In particular, the concept of deep mapping is discussed as a means of augmenting understanding of the city and its history from a narrative across time to a narrative across the physical space of the city. As itineraries, these course-based projects were replicated on site. In moving from the digital environment to the urban landscape, this article concludes by noting meanings uncovered and narratives formed as we moved through the physical space of the city.

Abstract Amendment to the Act on special rules of preparation and implementation of investment in public roads resulted in an accelerated mode of acquisition of land for the development of roads. The decision to authorize the execution of road investment issued on its basis has several effects, i.e. determines the location of a road, approves surveying division, approves construction design and also results in acquisition of a real property by virtue of law by the State Treasury or local government unit, among others. The conducted study revealed that over 3 years, in this mode, the city of Krakow has acquired 31 hectares of land intended for the implementation of road investments. Compensation is determined in separate proceedings based on an appraisal study estimating property value, often at a distant time after the loss of land by the owner. One reason for the lengthy compensation proceedings is challenging the proposed amount of compensation, unregulated legal status of the property as well as imprecise legislation. It is important to properly develop geodetic and legal documentation which accompanies the application for issuance of the decision and is also used in compensation proceedings.

Based on the experiences of a Koreatown scholar, the executive director of a Koreatown nonprofit, and a longtime resident student, the article advocates for greater attention to the complex and dynamic power structures of ethnic enclaves in community-academic partnerships. We discuss the changing landscapes of Koreatown as the global nexus of the Pacific Rim economy, the city of Los Angeles’s urban redevelopment plans, and growing diversity and inequality. Programs that aim to engage effectively with ethnic communities must reassess how knowledge is produced and conveyed, how we structure partnerships within stratified communities, and how to grow from issue-based partnerships to broader communities of interest.
