This study was implemented to identify the specific factors that lead to major contribution of floods in Klang River Basin. A thirty-year (1987-2017) database obtained from Department of Irrigation and Drainage (DID), the selected data was analyzed by using integrated Chemometric techniques. The finding from Correlation Analysis revealed strong correlation between stream flow and water level is more than 0.5 (= 0.799). The finding from Principal Component Analysis proved that the selected parameters were significant with the result of R2 > 0.7was applied as a main tool for further analysis. Based on the result, it revealed that stream flow and water level were the most significant hydrological factor that influenced flood risk pattern in Klang River basin. Based on the result from Statistical Process control (SPC), the finding showed that the Upper Control Limit (UCL) for water level was 30.290m. The plotted data which is more than 30.290 m can cause flood to occur in Klang River Basin. Thus, it is very important to continuously monitor and maintain the mitigation measure of flood in the study area to avoid flood to occur. This study also helps to provide visualization of flood pattern and show the optimal rates for the maximum limit for flood control in Klang River Basin.

Alappuzha district was severely affected by floods due to the intense rainfall in August 2018. A three member team with the assistance of local health workers was entrusted to assess the post flood situation and to assist the local health department to extend expertise mainly to control infectious diseases and propose suggestions regarding hygiene and sanitary measures to be taken for health and wellbeing of the community. Among the infectious diseases, Leptospirosis poses a significant public health issue in the flood affected areas of Alappuzha district. Majority of households had taken chemoprophylaxis for Leptospirosis as per standard protocol as also temporary rehabilitation camps in the flood affected areas. There was no episode of Acute Diarrheal Diseases (ADD), found in clusters in any of the areas. The number of dengue fever cases reported in post flood period was less when compared to previous year. Risk assessment is essential in post-disaster situations mainly concerned with the rapid implementation of control measures through refurbishment and improvement of health care delivery. The findings presented relate to an assessment carried out in Alappuzha district in September 2018 that included epidemiological situation analysis, appraisal of laboratory facilities for microbiology investigations, evaluation of health facilities and infrastructure available at Local Self Governments (LSGs).

The Yala River Basin (YRB) in Western region of Kenya has in the past experienced climate and weather extreme events that include floods. Floods have triggered loss of lives, destruction of property, outbreak of water borne diseases and siltation of arable land. This study utilized the Nedbør-Afstrømnings-Model (NAM) hydrologic model (available in the NAM Module of the MIKE 11 hydrodynamic model) on the Yala River Basin (YRB) to generate flood flows for water balance evaluation. The study utilized satellite imagery data for the period 1984-2010 sourced from the Regional Centre for Mapping of Resources for Development, rainfall (1980-2012) and river discharge (1947-2012) data sets from the Kenya Meteorological Department (KMD) and the Water Resources Management Authority (WARMA), respectively. Data quality control was statistically checked before sensitivity analysis, calibration, validation, and simulation of the flood flows. Daily water balance estimates for the Yala River Basin (YRB) over the period 1980-2010 were developed using the NAM hydrologic model. The results indicate that the mapped flood area extent varied by a value of 34.23 km2 over the period 1980-2010. The Yala River Basin (YRB) indicated an estimated inflow value of 4,814.72 MCM and outflow value of 4,578.23 MCM, with a coefficient of determination of 0.867. The difference between the inflow and outflow values was 236.49 MCM, that formed the flood flow or the water balance. This study concluded that the water balance value of 236.49 MCM was responsible for the floods recorded in the Yala River Basin (YRB) for the period 1980-2010, and it should be taken care of through flood risk reduction initiatives.

Flood is a major issue during monsoon season in Northern region of Malaysia especially in Muda River Basin. This study focused on the specific hydrology parameters that lead to the flood events in Muda River Basin, Kedah. There were 4 hydrologic parameters for thirty years of collected data from selected hydrology monitoring stations provided by Department of Irrigations and Drainage, Malaysia. The study applied Principal Component Analysis (PCA) and result shown that stream flow and suspended solid stand with highest correlation of coefficient variables with the changes of water level in the study area. Statistical Process Control (SPC) applied in this study was to determine the control limit for every selected parameter obtained from PCA. The Upper Control Limit value for water level reported from SPC analysis in the study area was 7.568m and starting from this level and above, the risk of flood is high to occur in the study area. This research proved that the flood risk model created in this study was accurate and flexible for flood early warning system at Muda River Basin.

The purpose of this study is to encourage ownership, responsibility and to develop stakeholders and policy makers for the river normalization program in the pre-construction, construction and post-construction stages. The use of the IPA method to measure community satisfaction in the quadrants on the Importance Performance Matrix map. The results of the study showed that the socialization from the Department of Water and Public Works, when the project was finished, was not in line with community expectations. Flood control projects that have been built, coordination with the contractor at the time of project implementation, socialization from the city government prior to project implementation, socialization from the city government when the project is finished, socialization from the river hall at the time before project implementation, socialization from the river hall at the time the project was completed, dissemination of information from the irrigation service prior to project implementation, and community involvement in project implementation. The process of land clearing, and the price agreement that has been reached. Improved land clearing, and price agreements that have been reached can be reconsidered because their impact on the benefits felt by the community is very small.

In many Nigerian states, urban flooding has resulted into the death of numerous people and destruction of properties worth billions of Naira. This study examined the vulnerability dynamics and urban flood hazardscape pattern within Gombe city with a view to providing bases for policy formulation (where necessary), enforcement and decision making on flood risk reduction for enable sustainable urban development. ASTER DEM and Landsat images (2000, 2010 and 2019) was used to generate Digital Terrain Model (DTM) and impervious surface areas. Rainfall data for 2000-2018 was used to examine rainfall trend using regression analysis. The result revealed that flood hazardscape and vulnerability dynamics are largely influenced by physical and social factors. The results for vulnerability dynamics shows that as at 2000, about 1.4km2 lies on the relatively low vulnerable area,4.1km2falls within the moderate, and about 14.6km2 falls on critical area. By 2010, only about 1km2 lies on the relatively low area, 5.2km2 occupied the moderate and about 15km2was found within the critically vulnerable area. In 2019, the vulnerability dynamics depicts that about 33.4km2, impervious surface (builtup area) existed, out of which 2.8km2 lies on the low vulnerable area, 9.4km2 on the moderately vulnerable and 21.2km2 in critically vulnerable areas. It is concluded that flood hazardscape and vulnerability dynamics in Gombe city is influenced by both physical and anthropogenic factors. It is recommended that planning departments should put into consideration urban flood hazardscape maps for future development so as to reduce the risk and control future exposure flood impact.

Haor is basin like structure where water remains either stagnant or in flash flooding condition during the months of June to November. In Bangladesh, haor areas are covered by Boro rice and produce a large amount. Severe flood damage this boro crop, so that the study was conducted to know the land use pattern and impact of flood on boro rice production. Both primary and secondary data were used for the study. Primary data were collected as survey sampling method (questionnaire, FGD, PRA etc.) from Itna and Mithamoin Upazilla where total respondents were 119. Secondary data were collected from Upazilla Administrations and Department of Agricultural Extension. Mainly descriptive statistics were employed to analyzing the data using MS Excel and SPSS. Most of the respondents were farmer. Major portion of their cultivable land are low land. Rabi is the only cropping season and during Kharif 1, and Kharif 2 lands became fallow due to inundate on flood water. In rabi season boro is the main crop and damaged by flash flood due to unavailability of controlling measures. Flood control measures would be taken to prevent huge loss of boro rice.

Rapid urbanization has opened the way to congested cities such as New
Delhi, Mumbai etc. and has been very challenging for urban drainage systems.
Poorly designed urban drainage systems, congestion of the stream channel,
overcrowding, expansion of urban infrastructure without appropriate
consideration of drainage issues, increase in paved surfaces, and climatic
conditions are the major causes of these disasters. As a response of these
circumstances, flash floods occur, resulting in both ground and surface water
quality deterioration. In order to have better results, competent planning, analysis,
and design of urban drainage skills are expected. In this study, ArcGIS software
is used to simulate the urban drainage system. The rainfall data required is
gathered from Irrigation and Flood Control Department, Delhi. For a drainage
region in SAID UL AJAIB, near Saket metro station, Delhi, India, the simulation
was done to understand problems associated with inadequate urban drainage.
From the results obtained, it was seen that some parts of Sail ul Ajaib area are
frequently affected by flooding.

AbstractShiga Prefectural Government uses “site safety level” to assess the flood risk of major floodplains in the prefecture in order to implement an integrated floodplain management system in society. Site safety level is determined based on a risk matrix expressing the relationship between the frequency of inundation and the degree of damage at sites surrounding a river channel complex. A department has been set up for floodplain management separate from river management. The Department of Floodplain Management promotes disaster mitigation measures, such as land use and construction regulations, and conservation of traditional flood control facilities, including flood prevention forests, open levees, and ring levees. Such traditional facilities are highly functional as green infrastructure because they are focused not only on disasters but also on a daily basis in order to wisely utilize local ecosystem service.

AbstractDespite massive flood controlling investments, perennial flooding continues to be a major challenge in the Greater Accra Metropolitan Assembly in Ghana. Previous studies have mostly considered the vulnerability of Accra to flooding induced by urbanization and climate change. This chapter examined the impacts of and adaptation strategies to flooding in two flood-prone residential areas in Accra. A survey was conducted among 320 household heads to ascertain local impacts of floods and community adaptation strategies. To obtain a broader picture of government interventions and challenges, key stakeholders such as personnel from ministries, departments, and agencies who are involved in city planning, and private urban planning consultants were interviewed. The study found that a notable driver of floods in Accra is blocked waterways, and flawed and ad hoc engineering works. About three-quarters of the households interviewed have suffered flood-related losses over the past decade such as housing damage, income, and even a death of a relative. Key flood control interventions included dredging prior to start of rains and sporadic demolition of unauthorized buildings on or near waterways to allow free flow of water. However, these interventions only seem to be ephemeral due to the rapid rate of littering and re-siltation of the waterways after few rain events. The study highlights the need for more pragmatic and robust engineering solutions to build resilience of Accra to floods.

With the advancement of urbanization, waterlogging disasters in China’s urban areas have increased significantly, especially in the Pearl River Delta region. Based on the literature published by government departments, this study analyzed the characteristics of urban waterlogging in the Pearl River Delta region from 2007 to 2019. The results show that the frequency and intensity of waterlogging disasters in the Guangdong-Hong Kong-Macao Greater Bay Area are very high. The types of rainfall that cause flooding mainly include strong convection, frontal rain and typhoon rain. In Guangzhou, the causes of waterlogging can be divided into external and internal causes. The external causes are extremely heavy rainfall and the tidal flooding of the outer river. The internal causes mainly include the hydrological effect of urbanization, the low standard of the drainage system, the insufficient function of flood drainage, and the poor management of flood control projects. These information determined in this study facilitates reasonable flood mitigation measures to be developed at the most critical locations in this region.

<em>Abstract.</em>—Two hundred years ago, Texas had 118,000 km of streams and rivers flowing unimpeded to the Gulf of Mexico—and one natural lake. Now there are more than 800 impoundments and few unregulated stretches of river. Reservoir construction increased the amount of aquatic habitat in the state, while dramatically changing most of the original habitat. These altered environments present challenges and opportunities to fishery managers charged with maximizing recreational fishing. Water level, flow, thermal regimes, and nutrient dynamics typically reflect human needs for flood control, water supply, and electrical power rather than natural weather patterns or seasonal cycles. Texas Parks and Wildlife Department has used propagated fishes to meet the challenges of these altered systems while diversifying fishing opportunities in Texas. Management of these environments necessitated decisions regarding the use of native sport fishes or fishes that were not native to the state but may, because of their habitat requirements or life histories, be more functionally suited to the newly created environments. This agency has created successful and in many cases extremely popular sport fisheries with the use of such fishes as Florida largemouth bass <em>Micropterus salmoides floridanus</em>, northern largemouth bass <em>M. s. salmoides</em>, smallmouth bass <em>M. dolimieu</em>, channel catfish <em>Ictalurus punctatus</em>, striped bass <em>Morone saxatilis</em>, palmetto bass (white bass <em>Morone chrysops </em>× <em>M. saxatilis</em>), walleye <em>Sander vitreus</em>, rainbow trout <em>Oncorhynchus mykiss</em>, and red drum <em>Sciaenops ocellatus</em>. As this agency continues its work to maintain healthy aquatic ecosystems and fishing opportunities with increased demand, we expect that the use of propagated fishes may become even more important in the future. This paper discusses the various altered environments we have been charged to manage, the consideration of various sport fishes for these environments and the resulting sport fisheries created through our use of native and nonnative fishes.

An enterprise resource planning (ERP) system is an integrated set of programs that provides support for core organizational activities. ERP is a software infrastructure embedded with “best practices,” or best ways to do business based on common business practices or academic theory. The aim is to improve the cooperation and interaction between all the organizations’ departments, such as the products planning, manufacturing, purchasing, marketing and customer service department. ERP systems is a fine expression of the inseparability of IT and business. As an enabling key technology as well as an effective managerial tool, ERP systems allow companies to integrate at all levels and utilize important ERP systems applications, such as supply-chain management, financials and accounting applications, human resource management and customer relationship management (Boubekri, 2001). ERP systems hold the promise of improving processes and decreasing costs. Furthermore, two important new frontiers for ERP systems are electronic business (e-business) and supply-chain management (Wang and Nah, 2001). The systems can connect with suppliers, distributors, and customers, facilitating the flow, the product and information. ERP systems implementation is costly and complex. In many cases, an ERP system is the largest single investment in any corporate-wide project. The software is expensive, and the consulting costs even more. Meta Group found that the average ERP systems implementation takes 23 months with total owners’ cost of $12 million (Stewart, 2000). The ERP systems implementation is the process where business process and ERP system match each other. Usually the firm has to change the business process per ERP systems. Sometimes most positions have to be redesigned according to the ERP systems. Thus the difficulties and high failure rate in implementing ERP systems have been widely cited in the literature (Davenport, 1998; Kim, Lee, & Gosain, 2005)). The failure percentage of ERP systems was determined by one study as ranging from 40 to 60% and from another study as between 60 and 90% (Langernwalter, 2000; Ptak and Schragenheim, 2000; Yingjie, 2005). Although the failure rates of these ERP implementations have been highly publicized, this has not distracted companies from investing large sums of money on ERP systems (Somers & Nelson, 2004). ERP systems provide companies with the means of integrating their business functions into a unified and integrated business process. As companies implement more enterprise based systems throughout their organizations, the need for integration of these systems becomes even more paramount. Expanding from the functional areas of accounting, human resources, and shop floor control to an enterprise-wide system has become a format for producing full organization integration. Over the past few years, limited research has been conducted about ERP implementation issues: mainly case studies in individual organizations have been reported. That is a motivation toward conducting empirical studies to explore critical factors that affect ERP systems implementation. This study presents the results of an empirical study that surveyed managers from seven corporations, who were identified as having a key role in ERP systems implementation, in order to assess empirically which CSFs are critical in leading a successful implementation of ERP systems. A factor analysis solution was used to derive factors affecting successful ERP implementation. These factors are: ERP implementation management, users aptitudes and communication and technical knowledge.

Abstract The primary goal of the first ever polymer flood field pilot at Milne Point is to validate the use of polymers for heavy oil Enhanced Oil Recovery (EOR) on Alaska North Slope (ANS). The specific objectives are systematic evaluation of advanced technology that integrates polymer flooding, low salinity water flooding, horizontal wells, and numerical simulation based on polymer flood performance data. Accordingly, under the co-sponsorship of the US Department of Energy and Hilcorp Alaska LLC the first ever polymer field pilot commenced on August 28, 2018 in the Schrader Bluff heavy oil reservoir at the Milne Point Unit (MPU) on ANS. The pilot started injecting hydrolyzed polyacrylamide (HPAM), at a concentration of 1,750 ppm to achieve a target viscosity of 45 cP, into the two horizontal injectors in the J-pad flood pattern. Since July 2020, HPAM concentration was reduced to 1,200 ppm to control injectivity and optimize polymer utilization. Filter ratio tests conducted on site ensure uniform polymer solution properties. Injectivity is assessed by Hall plots, whereas production is monitored via oil and water rates from the two producers. Water samples are analyzed to determine the produced polymer concentration. Supporting laboratory corefloods on polymer retention, injection water salinity, polymer loading, and their combinations on oil recovery, match rock, fluid and test conditions. A calibrated and validated numerical multiphase reservoir model was developed for long-term reservoir performance prediction and for evaluating the project's economic performance in conjunction with an economic model. Concerns related to handling of produced fluids containing polymer are addressed by specialized experiments. As would be expected in a field experiment of this scale, barring some operational and hydration issues, continuous polymer injection has been achieved. As of September 30, 2022, a total of 1.41 million lbs of polymer or 2.99 million bbls of polymer solution (~18.8% of total pore volume), placed in the pattern serves as an effective indicator of polymer injectivity. During the first half of the pilot period, water cut (WC) drastically reduced in both producers and over the entire duration, the deemed EOR benefit over waterflood was in the range of 700-1,000 bopd, and that too at a low polymer utilization of 1.7 lbs/bbl. Low concentration polymer breakthrough was observed after 26-28 months, which is now stabilized at 600–800 ppm in congruence with the WC. Although as indicated by laboratory experiments, polymer retention in core material is high; ~70% of the injected polymer propagates without any delay, while the remaining 30% tails over several PVs. History matched simulation models consistently forecasts polymer recovery of 1.5–2 times that of waterflood, and when integrated with the economic modeling tool, establish the economic profitability of the first ever polymer flood field pilot. Produced fluid experiments provide operational guidance for treating emulsions and heater-treater operating temperature. Over a duration of ~4.5 years important outstanding technical issues that entail polymer flooding of heavy oils have been resolved, which forms the basis of the success story summarized in the paper. The first ever polymer pilot is deemed as a technical and economic success in significantly improving the heavy oil recovery on ANS. The pilot has provided impetus to not only apply polymer EOR throughout the Milne Point Field, but has paved the way for additional state-funded research targeting even heavier oils on the ANS. The combined success of this work and the future work will contribute to the longevity of the Trans Alaska Pipeline System (TAPS).

The General Electric fan test facility has been re-installed and commissioned in the Laboratory for Noise and Vibration Control Research, located on the second floor of the Jonsson Engineering Center (JEC 2110) in the Department of Mechanical, Aerospace and Nuclear Engineering at Rensselaer Polytechnic Institute, Troy NY. RPI provides a unique venue to have a fully dedicated facility with access to experts and graduate students specializing in different fields. A congruence of new interested RPI investigators, generator aerodynamic experts, the return of old collaborators, and the need to reduce cost and losses in generator components, conspired to re-commission an improved version of the original setup. The results presented show good correlation between CFD and measured performance.

Experimentation is a very important part of education in engineering including mechatronics engineering, which is a relatively new field, combining three engineering disciplines: mechanical engineering, electrical engineering and software engineering. The equipments needed for experiments in mechatronics are usually expensive. A solution to make these expensive equipments achievable is to share them with other universities or research centers from different locations in the world. The goal of our team is to build a networked telerobot system so that the Internet users, especially researchers and students, can be able to control an autonomous robot able to explore a dynamic environment remotely from their home and share the robot system with the department. The particularity of the environment, in this case, is that the experiment uses grid lines painted on the floor, for robot navigation purpose. The system which is still under development will be able to increase the number of robots. The communication software technologies are based on PHP. A specific protocol over IP was designed for communication between the server and clients. The aim of this project is oriented toward providing a telerobot system with a high degree of local intelligence in order to overcome restricted bandwidth and transmission delay of the network.

The Yucca Mountain Project (YMP) is currently designing a geologic repository for high level nuclear waste. The design encompasses two distinct phases, the pre-closure period where temperatures within the repository will be controlled by active ventilation, and the post-closure period where the repository will be sealed. A prerequisite for designing the repository is the ability to both understand and control the heat generated from the decay of the nuclear waste. This decay heat affects the performance of both the waste packages and the emplacement drift. The ability to accurately model the complex heat transfer within the repository is critical to the understanding of the repository performance. Currently, computational fluid dynamics codes are being used to model the post-closure performance of the repository. Prior to using the codes on the project they were required to be thoroughly validated. Eight pilot-scale tests were performed at the Department of Energy North Las Vegas Atlas Facility to evaluate the processes that govern thermal transport in an environment that scales to the proposed repository environment during the post closure period. The tests were conducted at two geometric scales (25 and 44% of full scale), with and without drip shields, and under both uniform and distributed heat loads. The tests provided YMP specific data for model validation. A separate CFD model was developed for each of the four test configurations. The models included the major components of the experiment, including the waste packages (heated steel canisters), invert floor, and emplacement drift (insulated concrete pipe). The calculated model temperatures of the surfaces and fluids, and velocities, are compared with experimental data.

With the advent of new sources and technologies for obtaining data on the location and mutual location of objects and systems in general, as well as their integration into real – time control methods and algorithms, conditions have been created for more modern and high-quality use of computer technologies in the management of complex distributed systems (SRS). The components of such SRS are themselves complex distributed systems and have (or can potentially have), among other things, a negative impact on each other, that is, they represent or form a threat to each other. One of the most urgent tasks of our time is to develop various, usually highly computerized, tools and methods for parrying threats based on monitoring and forecasting the development of processes (including physical ones) that form the basis of these threats. This article discusses the problem of parrying one of the types of threats – flood. The issues of using various types of information coming from various sources – sensors for monitoring and forecasting the water level and associated flooding of the corresponding territories are considered. The system of using real-time automatically measured SRS parameters and their further application for digital decision support for parrying threats is a complex highly computerized technical system belonging to the class of the Internet of things. At the same time, it is one of the digital subsystems of the SRS that have a positive impact on other components of the SRS as a whole. All this information comes from various (technically and departmental) heterogeneous sources, so for its rapid and high-quality storage and use for monitoring, forecasting and parrying threats to the SRS, it needs specialized methods of analysis, structuring and distributed storage.

This research reports on a four-year project to restore a 1906 structure designed by architect William Ellsworth Fisher (1871–1937), one of Denver and Colorado’s most prominent architects and builders in the late 19th and early 20th centuries. It evaluates three competing decision-making process issues and the prioritization of each: restoration values (look and feel), integrated decision matrix (scope & process), and rules of thumb (architect’s methodology). It focuses on infrastructure to provide safety, historical authenticity, and maximum utility in preserving the look and feel of the original architectural design. This two-story masonry house was acquired in a bank foreclosure; it was in derelict condition, condemned by the health/building departments, requiring immediate remedial action to prevent catastrophic collapse. A 1959 renovation compromised the historic character of the interior when the single-family structure was converted into a rooming house. Substantial completion of the restoration was in the summer of 2019. In historic masonry structures with comparable heating degree days and cooling degree days, a similar, streamlined decision-making process can be developed to optimize the restoration outcome. Personal safety is always integral to this process. Standards relating to the treatment of historic properties—preservation, rehabilitation, restoration, and reconstruction should be maintained. Existing architectural features are recorded and preserved. False ceilings, chases, and the use of non-period materials and methods are avoided. There is a strong preference to remove and not encapsulate all environmental hazards. Masonry structures of the era are most at risk from poorly maintained or implemented moisture control systems. Intact roofs, gutters, and foundation drainage are prioritized. Sub-floor heating with a zoned, HE condensing boiler is the least disruptive process, maintaining the look and feel of the original structure. Ductless cooling is desirable. Development of an integrated prioritization matrix streamlines the decision-making process.

Municipal solid waste from Lee County and Hendry County is processed at the Lee County Solid Waste Resource Recovery Facility (the “Facility”). Lee County (the “County”) owns the Facility, which began commercial operation in December 1994. The Facility’s current permitted capacity is 1,320 tons per day (tpd), provided by two 660-tpd boiler units, at a reference waste of 5,000 Btu. Covanta Energy of Lee, Inc. operates and maintains the Facility under the terms of a Service Agreement with the County that runs through 2014. Covanta also designed and constructed the Facility. The expansion of this Facility will be the first new construction of a municipal waste combustion (MWC) unit since the New Source Performance Standards were adopted. Despite the County’s comprehensive recycling program, the amount of solid waste the County delivers to the Facility has increased each year since the Facility began operation, primarily due to population growth. In 1999, this amount reached the Facility’s guaranteed annual capacity of 372,300 tons. In 2000, the Facility processed over 392,000 tons of municipal solid waste, while the County landfilled nearly 44,000 additional tons of processible waste. Current population projections for Lee and Hendry Counties suggest that processible solid waste generation will continue to increase, reaching nearly 550,000 tons by 2010. Rather than landfilling processible waste generated in excess of the Facility’s current capacity, it is the County’s intention to expand the Facility by adding a third 660-tpd boiler unit which would increase the Facility’s permitted capacity to 1,980-tpd. The original application for the Facility’s Power Plant Site Certification anticipated such an expansion, including provisions for a third 660-tpd MWC unit. Certain provisions for this third unit were incorporated into the Facility’s design and construction as well. These included providing the physical space for the third unit, the physical space for an additional flue for the third unit, and sizing the tipping floor, refuse pit, and certain common equipment for three units. The expansion will require a second turbine-generator unit and expanded switchyard, an extension to the existing turbine-generator building, as well as the addition of a third boiler unit and air pollution control equipment. The expansion will also require modifications to certain equipment and systems common to all boiler units in order to meet the additional capacity requirements of the expanded Facility. As of February 2003, the County is waiting for the Florida Department of Environmental Protection to issue a draft PSD Air Permit and is on scheduled to go before the Power Plant Siting Board in September 2003.

The last revision of the American Petroleum Institute (API) guideline for the inspection of facility piping (API 570) includes tracer leak detection methods as an alternative to hydrostatic testing of buried pipelines. Tracer testing is a method in which a small concentration of a chemical label is added to the fluid inside a pipe. If a leak is present, analysis of air samples collected outside of the pipeline shows an increase in the concentration of the chemical vapor above background. Tracer test methods have been evaluated and validated by many studies. A summary of the cumulative data is described. Cumulatively, two hundred and one leaks were simulated under a variety of conditions. All but one of the leaks was detected. Of the one hundred and one control events in which no leak-indicating tracer was released, there was one false indication of the presence of the tracer. The autopsy of this event revealed that the false detection was due to operator error. Individual leaks have been located in large diameter pipelines regulated by the United Sates Department of Transportation. A case study is summarized in which a single leak in a forty-kilometer section of 0.4-meter diameter piping was located. This was a newly constructed yet to be commissioned pipeline built for the transport of natural gas. The single leak was located during the first day of sampling. Large refineries have used tracer methods to meet regulatory or facility inspection requirements. Refineries and chemical plants have used developing and established tracer test methods to meet regulatory requirements and to explore new ways of augmenting Asset Integrity Management programs. A six-year tightness testing program for a refinery/chemical plant facility including fifty kilometers of facility piping is summarized. During the most recent test season at the chemical plant, the frequency of detection of small leaks was one leak per kilometer of piping. None of the leaks detected during the six-year project accounted for the amount of petroleum product below ground surface. Significant releases at this facility were attributed to aboveground storage tanks. A final case study is included in which the location of a leak in an operating refinery pipeline and an associated aboveground tanks is summarized. The leak detection and location project was combined with a field evaluation of a new leak detection method for operating pipelines in which below-ground leaks are detected in samples collected above the ground. The leak in the supply line was located within the first twenty-four hours after the addition of the leak indicting tracer. Another leak through the floor of an associated aboveground storage tank was also detected on the day after the tracer was added by the presence of the leak detection tracer additive in samples collected below the tank. The tank also remained in continuous operation. Advantages of the test include: continuous operation of the piping and tanks during the test, avoidance any need to remove product, replace the product with water, treat the contaminated water or dispose of it. The use of a chemical tracer test method, designed for operating facility tanks and piping can in many instances serve well as an alternative to hydrostatic testing for meeting API 570 standards.
