Luncheon Keynote Presentation Dr. Li-San Hwang (黃立三博士), Founder and CEO/Chairman Emeritus Tetra Tech, Inc. Dr. Li-San Hwang received his B.S. in Civil Engineering from National Taiwan University, and his M.S. from Michigan State University in 1962. He received his Ph.D. in Civil Engineering from the California Institute of Technology in 1965. Dr. Hwang joined Tetra Tech in 1967. In a short time, Dr. Hwang was able to secure many projects and attracted many talented engineers. In 1974, Dr. Hwang was named Vice President. Under his leadership, Dr. Hwang’s division developed numerous unique models to solve complex environmental and water resource problems, notably tsunami generation and propagation, storm surge and coastal flooding, ecological issues, and watershed management. These models were instrumental in solving the complex problems faced by clients. In 1982, Tetra Tech was acquired by Honeywell. Subsequently, Honeywell incorporated the company’s defense-related business into its principal business. The Water Management Group left in Tetra Tech was managed by Dr. Hwang. Later he expanded the business into coastal pollution discharge and hazardous waste management. In 1987, Dr. Hwang was named President and CEO of Tetra Tech. In the following year, Dr. Hwang led a “management buy-out” of Tetra Tech from Honeywell. As an independent company, Tetra Tech’s business grew rapidly, with revenue doubling from $25 million to $51 million in three years. To finance the company’s growth and pay off existing bank debt, Tetra Tech went public in 1991. After the company went public, Dr. Hwang led Tetra Tech to consistent strong growth, and increased profitability and return on investment. As a result, Tetra Tech was named by Forbes, Fortune and Business Week as one of the “Best Small Companies” a total of eight times. By 2003, Tetra Tech’s revenue exceeded $1 billion, and Engineering News Record (ENR) ranked Tetra Tech as the largest environmental consulting firm in the United States. From the “management buy-out” in 1988 until Dr. Hwang’s retirement in 2006, the company’s stock price increased 84-fold due to Tetra Tech’s exceptional results and continual growth over that period. Dr. Hang published extensively. He was one of the world’s leading experts in tsunamis, and served as an advisor to numerous government and professional society committees. Dr. Hwang received numerous professional awards, including the Entrepreneur of the Year Award for the Los Angeles region, and Lifetime Achievement Awards from ChineseAmerican Engineers and Scientists Association of Southern California (CESASC) and Achievement Award from the Monte Jade Science and Technology Association.

We developed an approach to assess environmental flows in estuaries. The method consists of three steps including identifying ecosystem protection objectives, determining initial environmental flows based on habitat simulations, and providing recommended flow regimes after balancing water requirements for ecosystem protection and irrigation processes. The method was applied in the Yellow River Estuary. Based on the results, we defined a boundary of environmental flows as limits in water allocation for ecosystem protection, and provided recommended environmental flows which may be accepted by stakeholders requiring water for other needs. Integration of diverse objectives was suggested to be a critical issue in environmental flow assessment. Water-saving measures should be employed to improve water-use efficiency in balancing water utilization. Key words: environmental flow assessment; water resources allocation; Yellow River Estuary The Impact of the New National Pollutant Discharge Elimination System Permit Requirements on Vector Control Renjie Hu, Ph.D. Supervising Public Health Biologist, California Department of Public Health, Vector-Borne Disease Section, Ontario, CA 91730 Abstract: Effective vector control includes pesticide application and is considered an important part of preventing vector-borne disease outbreak. The use of pesticides for public health in California is typically regulated by environmental and public health agencies including the Environmental Protection Agency, the California State Water Resource Control Board (the State Water Board), the California Department of Public Health, and the California Department of Pesticide Regulation. Recently, the State Water Board adopted a General National Pollutant Discharge Elimination System Permit for Residual Pesticide Discharges for Vector Control Applications. The purpose of this permit is for clean water and reduction of pesticide use. It also imposes monitoring, testing and reporting requirements. Under the permit, the agencies that apply pesticides are required to conduct both visual and physical monitoring of the pesticide applications and report the results to the board. The State Water Board and vector control agencies are working closely to develop a mutually beneficial plan to protect public health and environment. The issues and concerns raised and the impact of the permit on vector control will be presented in detail.

On the July 16-17, 2011 weekend, a section of a major Los Angeles freeway, the I-405, was closed for 36 hours. We measured UFPs and other pollutants at two fixed locations, one upwind and one downwind, and at various distances from I-405 using a mobile monitoring platform (MMP) on Fridays, Saturdays, and Sundays before, during, and after closure. On the closure Saturday on July 16, I-405 traffic flow was reduced by ~90% relative to non-closure Saturday observations. Downwind of I-405, fixed site measurements showed the following reductions: 83% of particle number concentration (PNC), 36% of PM2.5, and 62% of black carbon (BC). Daily average UFP size distributions were bimodal for non-closure conditions (nucleation modes ~20 nm, accumulation modes ~60 nm), but only showed an accumulation mode ~50 nm during closure. Spatial measurements from the MMP confirmed no nucleation mode was detected at any location 0 to 350 m downwind during closure. During closure, major freeway traffic was reduced basin-wide, with greater reductions closer to the I-405 closure center, compared to five selected control Saturdays. PM2.5 concentrations from eight stationary monitoring stations were reduced between 18 and 36% relative to the same control days. In 2011, non-closure emission factors (EFs) were 5.0, 2.7, and 3.4 x 1013 particles vehicle-1 km-1 for Friday through Sunday respectively. After accounting for instrumental and traffic flow differences, PNC in 2011 was 73% lower than 2001 at the same study location. The outcome of the natural experiment during the I-405 closure serves as a proof-of-concept that traffic reduction can improve local and regional air quality in sprawled urban regions such as Los Angeles, CA. Objectives and Measures to Mitigate PM 2.5 Air Pollution in Guangzhou City during the 12th Five-Year Plan (2012-2016) Liang, Jin-quan, Former Chief Engineer Guangzhou City EPA, China Abstract: For the 12th Five-Year Plan (from 2012 to 2016), the City of Guangzhou, China, has established its objectives to mitigate PM 2.5 air pollution, and it will implement as many as ten measures to achieve the objectives. To monitor and control PM 2.5 air pollution, Guangzhou has done sufficiently technical preparations. The City is one of the first municipals in China to start real-time automatic monitoring of air quality. Since 2009, the City has started a trial project to monitor PM 2.5. During the 17th Asian Game in Guangzhou in October 2010, PM 2.5 was one of the monitoring parameters to monitor and control air quality. Since 2004, the City has continuously to reduce sources of air pollution from industrial facilities (such as power plants), automobile emissions, and dust discharge from construction sites. For the 12th Five-Year Plan (from 2012 to 2016), PM 2.5 air pollution will be the focus of air pollution control for Guangzhou. The city will implement the measures to effectively mitigate its air pollution: control consumption of coal; control automobile emissions; regulate emission and dust discharge from power plants; regulate discharge of VOCs into the atmosphere; reduce dust discharge from construction sites, transportation and storage facilities; regulate smog discharge from restaurants; regulate burning of trash and dry crops in countryside; complete air pollution monitoring system and information broadcasting mechanism; initiate significant air pollution early warning and response system; and promote public participation on air pollution control. Temporal Trend and Spatial Distribution of Emission Inventory of Hazardous Heavy Metals Pollutants in China HezhongTian*, Ke Cheng, Dan Zhao, Long Lu,Yan Wang, and JiajiaGao School of Environment, Beijing Normal University, Beijing 100875, China. Presenter and Corresponding Author: Dr. H.Z.Tian. E-mail: hztian@bnu.edu.cn Abstract: With the continuous economic development and rapid urbanization in China, large amounts of fossil fuel consumption and intensive industrial activities have caused substantial release of hazardous trace elements into the atmosphere, which have aroused great concerns for their adverse effects on eco-environment and public health. An accurate and complete emission inventory can help both modeler community and policymakers in assessing the current status of environmental contaminations, identifying major emission sources and spatial distribution characteristics, as well as understanding the contribution of the atmospheric pathway to the contamination of terrestrial and aquatic environments. In this study, a multipleyear comprehensive emission inventory of atmospheric hazardous trace metals including mercury (Hg), arsenic (As), selenium (Se), cadmium(Cd), chromium (Cr), antimony (Sb), nickel (Ni), and Antimony (Sb) in China for the period of 1980-2009 has been developed, which covers major anthropogenic sources and a bottom–up approach is adopted to compile the inventory for the sources where possible. Our results indicate that coal combustion accounts for a major source of Hg, As, Se, Cr, Pb, Sb, and Ni in China. Another major source category is nonferrous metal smelting, which ranks the largest source of atmospheric emissions for Cd, and also contribute a very large proportion of other elements. As for spatial allocation, the majority of anthropogenic atmospheric trace elements emissions are demonstrated to be highly distributed among regions of costal eastern and northern China, which can be partly explained by the rapidgrowing demands for fossil energy and the increasing industrial production activities in these regions. We believe that this inventory will be benefitfor better understanding the historical and current situation of these hazardous trace elements emissionsandpromulgating more effective ways for preventing the environmental pollution and poisoning accidents by the policymakers and relevant researchers.

Evaluation on the Performance of Air Pollution Control for Chinese Cities Guojun Song Environmental Policy and Planning Institute (EPPI), Renmin University of China Abstract: This presentation is the results of a research which is finished recently. The evaluation shows the performance with the evidences from three aspects: air quality and trend, pollution control activities, and information publication. For the air quality and its trend, the picture, including 287 larger cities, three indicators, daily mean value, rate exceeded grade 2 ambient air quality standards (AAQS) and days complying AAQS, population exposure, is given within 2005 to 2010. Generally speaking, the air quality for most cities is still poor and worse for the PM10 and SO2; For the pollution control activities, the most effective measure is the centralized heating system to north cities for PM10, same for SO2, and NO2 emission density for NO2. For air quality information publication, the urban residents concern the information much. However, the information published by municipal EPB is very poor. The policy to PM10 and SO2 is effective, not effective to NO2, generally speaking. 高雄港區溫室氣體與空氣污染物排放量比較 葉雨松 高雄市是一工業城市,轄內的高雄港是 2010 年排名全球第 12 大貨櫃港,周圍圍繞著臺灣最重 要的重工業區。當局歷年來對工廠固定污染源的管制不遺餘力,但是對船舶的空氣污染掌握及 管制仍屬空白。本研究建立了高雄港 2009 年、2010 年港區遠洋船舶排放 SOx, NOx 等空氣污 染物及溫室氣體的排放清冊,並與該年度港區鄰近工業區之排放量進行比較,提供未來研擬管 制策略之參考。 關鍵字:高雄港,排放清冊,溫室氣體,空氣污染,船舶 TECHNICAL SESSION 3 Soil and Groundwater Remediation Moderators: Rebecca Chou, Ph.D., P.E. Section Chief, Los Angeles Regional Water Quality Control Board, Cal EPA Jeff Kuo, Prof., California State University at Fullerton Current Status of China’s Remediation Market and Case Studies Jun Ma, Ph.D. BCDG Environmental Remediation Co. Ltd Abstract: China has been undergoing a rapid industrialization over the past half century, but this does not occur without consequences. Inappropriate management and disposal practices of hazardous waste and chemicals, spillage, leak etc., as related to past and ongoing industrial activities, have contributed to the deteriorating quality of soil, groundwater and/or sediment in many regions across the country. Land contamination has become one of the major challenges facing the government and the public. However, not until recently has the urgency of addressing the contaminated land been fully realized, partially because of the raised public awareness following a series of serious environmental incidents that have occurred during the past decade. A systematic strategy is currently being developed to deal with the land contamination issue. As a part of the efforts, Ministry of Environmental Protection (MEP) has published four guidelines in 2009 seeking public comments, including “The Technical Specification for Environmental Site Investigation (Draft)”, “Guidelines for Risk Assessment of Contaminated Sites (Draft) “, “Guidelines for Soil Remediation of Contaminated Sites (Draft) “, and “Technical guidelines for Environmental Monitoring of Sites (Draft)”. In addition to that, the “12th Five-Year National Planning for Comprehensive Prevention and Control of Heavy Metal Pollution " and the “National Groundwater Pollution Prevention Plan (2011-2020)” were approved in February 2011 and August 2011, respectively. Last but not least, MEP internally approved the “Interim Measures on Management of Soil Pollution in Contaminated Sites (Draft)”, which is applicable to contaminated sites where land use or land ownership has changed. This presentation provides two case studies of remediation projects that BCEER is involved. The first case study summarizes a large-scale soil remediation projects at a former chlor-alkali plant, whose contaminants of concern (COCs) were mostly chlorinated volatile organic compounds (CVOCs), such as 1,2-dichloroethane, vinyl chloride, chloroform. Approximately 1.5 million cubic yards of CVOC-contaminated soils were treated using mechanically-enhanced VOC desorption technology within 2 years. A variety of safety measures were adopted during project implementation to mitigate risks posed to construction workers and adjacent communities. In addition, pilot test of CVOC-contaminated groundwater was completed at the site as well. A total of 7.2 tons of EHC remediation reagents were injected into subsurface (0.5% dosage in mass), resulting in the reduction of CVOC concentrations in excess of 95%. The second case study involves the remediation of hexavalent chromium-contaminated soil and groundwater at an auto-part manufacturing facility. A comprehensive remedial approach was followed for the site, consisting of active remediation, engineering control, and natural attenuation. The project is still on-going, but the remedial approach appears to work relatively well based on the preliminary results. Consolidation of Risk Assessment and Management of Contaminated Lands in Taiwan Wan-Ying Tsai*、Pek-Hoon Lim*、Yu-Jen Chung*、Hung-Teh Tsai** * Sinotech Engineering Consultants INC, R.O.C. ** Soil and Groundwater Pollution Remediation Fund Management Board, Environmental Protection Administration, R.O.C. Abstract: To prevent and remedy soil and groundwater contaminated, improve living environment, protect human health, and ensure sustainable utilization of land and groundwater resources. Taiwan Environmental Protection Administration (Taiwan EPA) passed the Soil and Groundwater Pollution Remediation Act in 2000 and targeted several tens of environmental pollutants by setting control standards. In accordance with the Soil and Groundwater Pollution Control Site Preliminary Assessment Regulations, the sites are divided into control sites and remediation sites, which are then further classified into farm lands, factory, gas station, storage tanks, illegal disposal sites, and others. Since the implementation of the Soil and Groundwater Pollution Remediation Act, 12 years of statistics indicate Taiwan once had over 1,400 hectares of contaminated sites listed, with only 480 hectares of de-listed sites which are all farm lands. Approximately 700 hectares of factory or illegal disposal sites are highly contaminated and still on-list. There were only 3 sites of the 56 high-risk remediation sites de-listed, because of the pollutants concentration lower than control standards. To allow the continued use or revitalize the sites while protecting human health and ecology, the Taiwan EPA agrees that the implementation may remove the land use limitations in accordance with Article 24 of the Soil and Groundwater Pollution Remediation Act, where there is a financial or technical impracticability, or a need to accommodate land development, and remediation goal can be achieved with the approval from the competent agency via appropriate remediation methods and risk management strategy. Pursuant to Article 24 of the Soil and Groundwater Pollution Remediation Act, Taiwan EPA has created the Human Risk Assessment Guideline, Risk Management Guideline and Risk Communication Guideline in the recent years. It is also beginning to establish the Ecological Risk Assessment Method. A recent case study where there is no responsible party for the site indicates that after health risk and financial assessments, the government needs to pay for remediation expense as high as US$ 3.5 million. The cost is not worth the value of the land. If risk managements are adopted, including denial measures, groundwater use limited and periodic monitoring, the site will achieve risk level with only 10% of the expense. The residents can be safeguarded. The assessment/determination methods and review mechanism are more uncertain than the regular cases where control standards are the basis for de-listing, thus Taiwan has not technically impractical cases. However, sites contaminated by dense-non aqueous phase liquid still may face technical impracticality. The relevant execution and management are to be carried out. To utilize the contaminated lands sustainably, Taiwan EPA is currently establishing contaminated sites revitalization framework. The concept of land life cycle management is then raised to adopt a two stage execution framework of “restricted-land release” and “land redevelopment” to attempt reducing the possible conflicts between environmental and landdevelopment regulations. “Restricted-land release” is land restriction removed under risk level by technical tools such as site investigation, remediation technology, and risk assessment, etc. They can sure both human health and living environment are protected during land development and future use. In addition, Taiwan has a robust renewal regulation for outdated industries and rural development. To consolidate reuse mechanism of contaminated lands and land development regulations, “land redevelopment” system prioritizes the three development objects of industrial, residence, and infrastructure. We raise economic incentives for expecting to accelerate the contaminated lands revitalization. Keyword:risk assessment、contaminated lands、revitalization Application of microwave irradiation in the degradation of persistent organic pollutants Dr. Xitao Liu Abstract: In this study, microwave heating was adopted to take the place of conventional heating to induce hydrothermal reaction. Under microwave irradiation, NaOH and H2O absorbed microwave energy by space charge polarization and dipolar polarization and instantly converted it into thermal energy, which initiated the occurrence of hydrothermal reaction that involved with zero-valent iron. X-ray diffraction (XRD) analysis found Fe3O4/NaFeO2 and confirmed the occurrence of microwave-induced hydrothermal reaction. The developed microwavehydrothermal reaction was employed for the dechlorination of PCBs. Hexadecane containing 100 mg/L of Aroclor1254 was used as simulative transformer oil, and the dechlorination of PCBs was evaluated by GC/ECD, GC/MS and ion chromatography. For 10 mL simulative transformer oil (with 0.3g iron powder, 0.3g NaOH and 0.6 mL H2O added), almost complete dechlorination was achieved by 750 W microwave irradiation for 10 min. The effects of important factors including microwave power and the amounts of reactants added, on the dechlorination degree were investigated, moreover, the dechlorination mechanism was suggested. Microwave irradiation combined with the common and cheap materials, iron powder, NaOH and H2O, has provided a fast and cost-effective method for the treatment of PCB-containing wastes. Regulatory framework of Waste Discharge Requirements for Soil and Groundwater Remediation Eric Wu, Ph.D., P.E. Cal/EPA Los Angeles Regional Water Quality Control Board Abstract: All discharges are subject to the California Water Code 13263 and the responsible party will be issued with Waste Discharge Requirements (WDRs) by the Regional Board. The purpose of WDR issuance is to protect beneficial uses of groundwater. The common soil and groundwater contamination in the greater Los Angeles area largely results from leaks of underground storage tanks (USTs), or industrial operations. To effectively and timely mitigate petroleum hydrocarbon, volatile organic compound and/or hexavalent chromium contaminated soil and groundwater, the Regional Board has adopted a general permit which allows the use of several agents. If the remediation method is not included in the general permit, an individual site-specific permit will be adopted by the Regional Board. Associated with either the general permit or an individual permit, each discharger shall also be issued with a Monitoring and Reporting Program (MRP). The MRP prescribes sampling requirements and requires periodical report submittal. All the submitted information including monitoring well coordinates, groundwater quality, and hydrogeological records are uploaded to GeoTracker database. GeoTracker database compiles data from various dischargers and provides an overview of regional groundwater quality to general public. Through issuance of WDRs, groundwater quality, beneficial uses and public health are better managed and protected. Dynamic Duel-Phase-Extraction Treatment of Petroleum Hydrocarbons Contaminated Soil and Groundwater at a Former Leaking Underground Storage Tank Site Rain Zeng (PhD, PE); Justin Soo Hoo; Dave Reinhard; David Cheng (PhD, PE) Accord Engineering Inc. Keywords: Dual-phase-extraction, soil and groundwater remediation, leaking underground storage tank site, petroleum hydrocarbons, gasoline and additives, natural attenuation Abstract: A dual-phase-extraction soil and groundwater remedial pilot study and treatment was performed at a former leaking underground storage tank site located at northern California. The DPE pilot study and treatment were conducted to assess the effectiveness and implementability of DPE technology to remediate gasoline and associated petroleum hydrocarbons from the soil and groundwater at the Site. During the same period the entire Site was actively remediated to treat the hot spots using a full-scale, extraction well network. A trailer-mounted DPE system was operated for a 5-day, 15-day, 35-day, and 30-day phases over a one-year period at the Site. Comprehensive field and laboratory data were collected including field measurements of groundwater levels, vacuum pressures, hydrocarbons, oxygen, carbon dioxide, and methane in the vapor phase, and collection of vapor and groundwater samples for conformational laboratory analysis. During various phases of the DPE treatment, the effective radius of vacuum influence, the flow rates of extracted vapor, and the achievable contaminant-concentration extraction rate were evaluated. The accumulated mass removal was calculated and the natural attenuation potential was assessed based on soil vapors concentrations of hydrocarbons and natural attenuation parameters oxygen, carbon dioxide, and methane. Using a dynamic approach, more than 700 lbs. of hydrocarbons was actively removed through DPE during this treatment period. Also the hydrocarbons removed by in situ biodegradation were estimated to be over 1,000 lbs. A Case Study of Site Investigation and Remediation at A Chemical Manufacturing Facility in the San Francisco Bay Area Xinggang Tong, Ph.D., P.E. Principal Engineer OTG EnviroEngineering Solutions, Inc. 7700 Edgewater Drive, Suite 260, Oakland, CA 94621, USA Abstract: This private chemical company operated a 21-acre manufacturing facility in the San Francisco Bay Area from 1956 through 2002. Its rise and fall from the 1980s to 2002 were closely tied to the manufacturing activities of integrated circuit boards and chips in the Bay Area. For over two decades, the author provided environmental support services to the company when the facility was in operation and led a team of environmental scientists and engineers for soil and groundwater investigation and remediation after the facility was shutdown in 2002. The site was recently re-zoned for residential redevelopment. The author will give an overview of environmental compliance requirement and regulatory agencies involved during the facility’s active operation time. The author will then discuss in details of the nature of soil and groundwater contamination and remediation activities. Two regional groundwater plumes exist in the area: one is dominated by 1,2-DCA and the other is dominated by TCE, PCE, and DCE. On-site contamination included chlorinated VOCs, petroleum hydrocarbons (BTEX, TPH-gas, TPH-diesel), SVOCs (dominated by pentachlorophenol), and heavy metals (arsenic, copper, chromium, and lead). Remediation activities conducted to date included capping (3-acre area was capped in place), excavation and off-site disposal, in-situ pH neutralization, in-situ chemical oxidation with hydrogen peroxide, insitu bioremediation, and 10 years of groundwater extraction and treatment operations. TECHNICAL SESSION 4 Surface Water and Watershed Management (2) Moderators: Charles Cheng, Ph.D. Engineering Geologist, San Diego Regional Water Quality Control Board, Cal/EPA Guangyu Wang, Ph.D., Deputy Director, Santa Monica Bay Restoration Commission Risk Assessment of Water Environment Based on the Respond Net Model (RNM) in Haihe River Basin Estuary of China Liu Jingling,* Chen Qiuying State Key Joint Laboratory of Environmental Simulation and Pollution Control & School of Environment, Beijing Normal University, 100875 Beijing, China *Liu Jingling e-mail: jingling@bnu.edu.cn Abstract: Ecological risk assessment for water environment is significant to water resource risk management of basin. Effective environmental management and ecosystems restoration such as the Haihe River Basin requires holistic understanding of the relative importance of various stressor-related impacts throughout the basin. The risk sources of Haihe River Bain was concluded to industrial sources (mining industry and contaminated industry), agricultural sources (farming, animal husbandry and aquaculture industry), domestic sources (domestic sewage and urbanization) and hydraulic engineering sources. This paper comprehensively considered the interactions of many kinds of sources, stressors, habitats and endpoints based on the characteristics of estuary water environment. We take Haihe River Basin Estuary as examples to carry out risk assessment model-respond net model (RNM) applied in regional scale. The results indicated urbanization was the biggest source, the second was shipping and then was industry, their risk scores are 5.65, 4.71 and 3.68. The habitat destruction was the largest stressor with the risk scores (2.66), the second was oxygen consuming organic pollutants (1.75) and the pathogens (1.75). These three stressors were the main influencing factors of the ecological pressure in the study area. For habitats, open waters (9.59) and intertidal mudflat (6.80) were enduring the bigger pressure. Ecological service values damaged (30.54) and biodiversity decreased(24.99) were facing the biggest risk pressure. Comparing of Ecological Risk of Single Pollution in Haihe River Basin Estuary: Distribution and characteristics of seven heavy metals in sediment in the representative ecological unit rivers, lakes and estuaries of Haihe River Basin were analyzed.The sequence of risk from high to low of the representative eco-units was as follows: Zhangweinan River (2278345.68 risk level high) >estuary (161914.74 risk level high) >Luanhe River (191.54 risk level moderate) > Baiyangdian Lake (120.95 risk level moderate). According the results some suggestions were given for the water environment safety and management of the Haihe River Basin: control water pollution, balance water-salt, monitor ecological factors and face risk management. Case Study – Use TMDL to Control and Restore Sediment Impairment in the Los Penasquitos Lagoon Charles Cheng, Ph.D. San Diego Regional Water Quality Control Board ccheng@waterboards.ca.gov Abstract: About 90% of historical salt marsh wetlands in California have been lost to urban development. Los Peñasquitos Lagoon (LPL) is one of the few remaining and irreplaceable coastal lagoons in southern California providing valuable estuarine habitat as well as numerous other important beneficial uses, including salt marsh and estuarine habitat support for migratory and resident birds and other wildlife, protection from flooding, and assimilation of water pollution. LPL suffers from excessive sedimentation due to a variety of man-made causes, including construction of the railroad, Highway 101, I-5 freeway, intense urban developments, and hydromodification. LPL is currently placed on the CWA section 303(d) List of Water Quality Limited Segments due to sedimentation and siltation. The beneficial uses that are impaired by excessive sedimentation are those associated with protection of aquatic life (e.g., Estuarine Habitat, Marine Habitat, Rare, Threatened, or Endangered Species, and Preservation of Biological Habitats of Special Significance, etc.). In order to control and restore this impairment and to meet the requirements of CWA section 303(d), the San Diego Regional Water Quality Control Board developed and adopted a Sediment TMDL for the Lagoon. The TMDL establishes two parallel numeric targets to control sedimentation and restore the lagoon: (1) reduce sediment discharge from surrounding watersheds into the lagoon by 67%, to the discharge level that existed in the early 1970s; and (2) take actions in the lagoon itself as needed to restore salt marsh vegetation to 80% of the acreage that existed in 1973. The TMDL identifies Responsible Parties that include the Cities of San Diego, Del Mar, and Poway; the County of San Diego, Caltrans, numerous entities regulated under the statewide General Construction Storm Water Permit, the statewide General Industrial Storm Water Permit, and the statewide Phase II General Municipal Storm Water Permit. The TMDL requires Responsible Parties to develop and implement Comprehensive Load Reduction Plans (CLRPs), and set a timeframe to meet the TMDL within twenty years. The Occurrence of Controlled Substances in Hospitals Effluents and Surface Waters Angela Yu‐Chen Lin Graduate Institute of Environmental Engineering, National Taiwan University yuchenlin@ntu.edu.tw Abstract: Occupational exposure to controlled substances has long been recognized as a potential health hazard. However, exposure to controlled substances such as narcotics is not limited to the pharmacies and hospitals where these drugs are prepared and administered to patients. In fact, it is very likely that exposure can occur through environmental waterways, potentially impacting the population and local ecological systems even more broadly. Water scarcity has long been an issue, forcing us to rely increasingly on degraded water sources such as recycled wastewaters for drinking water. Water resources are prone to pollution through natural and anthropogenic contaminations, resulting in death and disease worldwide. A major source of water pollution is the treated, undertreated and untreated wastewaters released from wastewater treatment plants (WWTPs). In Taiwan, hospitals, drug production facilities and sewage treatment plants also release their effluents into neighboring waterways. Therefore, all pollutants not completely removed during the treatment process are released and enter the receiving water bodies. Among these are pharmaceuticals that have raised significant concerns in the twenty‐first century. We have investigated the occurrence of controlled substances in hospital effluents and rivers in Taipei, Taiwan, and report the concentrations of controlled drugs used as prescription medication or drugs of abuse. Target compounds include: methamphetamine, ketamine, meperidine, morphine, codeine, cocaine, methadone, fentanyl and sufentanil. The presence of these contaminants in the aquatic environment may pose significant risk to aquatic and human life. Further studies are needed for verification and may contribute to the development of sustainable strategies for environmental remediation.

The impact of tile drains on nitrate loss at the watershed scale is not well quantified. SWAT2005, with its modified tile drain component, was used to evaluate nitrate loss through tile drains in a heavily drained watershed, Sugar Creek watershed in Indiana. Monthly stream flow predictions resulted in Nash-Sutcliff Efficiency values of 0.88 for both the 5-year calibration period and the 6-year validation period. Monthly nitrate-N loads were also predicted well, with Nash-Sutcliff Efficiency values of 0.63 in the calibration period and 0.67 in the validation period. Nitrate-N load from tile drains was added as an output, and the simulated nitrate loss through tile drains was compared with nitrate losses from surface flow, groundwater and lateral flow. The estimated median percentage of monthly nitrate loss entering Sugar Creek that flows through tile drains ranged from 0% to 37%, and was more than 30% for three months, April to June. Results like these could be used in estimating potential nitrate reductions at the watershed level that would be achieved by implementing drainage-related conservation practices throughout the watershed. Improvement of Nitrogen Removal Through Riverbank Restoration Yuansheng Pei and Hua Zuo Beijing Normal University, Beijing 100875, PR China, yspei@bnu.edu.cn Abstract: Ecological restoration of hard embankment is increasingly significant in China. However, in restoration practices of degraded riverbank, less attention has been paid to purification aspect of the riverbank while the hydrological and ecological functions are frequently addressed. A new media screen technique with soil bioengineering had been developed and the restored riverbank was endowed with purification function. An inner zeolite layer within the riverbank could adsorb ammonium and remove nitrogen by both autotrophic and heterotrophic processes. Both the intensified test and the normal test were conducted by artificial pumping and natural hydrodynamic, respectively. The average removal rate of total nitrogen could achieve 63.2 mg m-3d-1 in the intensified test while ammonium and total nitrogen concentrations moderately decreased from outside to inside layers in the normal test. In particular, natural biogeochemical nitrogen removal was driven by fluctuations of water level on both sides of the riverbank. Without extra energy consumption, the newly developed technique could be extended to more riverbank restoration projects. Development and Use of Biological Objectives for Protection and Ecological Restoration of Wadeable Streams in California Guangyu Wang, Ph. D. Santa Monica Bay Restoration Commission, CalEPA Abstract: This presentation provides an overview of the efforts made by the State of California water quality and natural resource management agencies to develop biological objectives as a regulatory tool for protecting the ecological health and facilitating ecological restoration of wadeable streams in the State. Traditionally and until very recently, water quality criteria used in the State have all been based on physical and chemical parameters. However, there has been growing recognition that physical and chemical criteria alone are not sufficient in protecting aquatic life and the health of the aquatic ecosystem. Biological criteria are necessary not only for determining directly whether the aquatic life beneficial uses are supported by a waterbody, but also for assessing whether the physical and chemical criteria are effective and adequate in protecting these beneficial uses. The development of biological objectives by the State of California is guided by a set of basic principles which include a) biological objectives should be developed for all waterbody types, b) multiple indicators should be used for biological objectives, c) biological objectives should include numeric endpoints, and d) there should be statewide consistency with regional flexibility. But given the highly variable and complex nature of streams in the State, the responsible agencies, mainly the State Water Resources Control Board chose to first focus on development of biological objectives for the wadeable streams. Similar to chemical criteria, the biological objective development has been done through a stakeholder process involving collaboration and participation of a stakeholder advisory group, a scientific advisory group, as well as a regulatory advisory group. Key steps of the development process include establishment of reference condition, identification of waterbody expectation, stressor identification, definition of numeric endpoint and/or quality indices, and finally rule making.

Among many photocatalysts, titania has been widely studied for its wide application in photocatalysis, solar cells, and hydrogen production because of its nontoxicity, stability in aqueous solution, and no photocorrosion. However, most applications so far are limited to UV light irradiation because the light absorption edge of pure titania is less than 380 nm. Recently, Ritterskamp et al reported that the light-absorption characteristics in UV-visible region (ca.360∼800nm) of TiSi2 are ideal for solar applications and have a good photocatalytic activity of splitting water into hydrogen. Shock wave action of high temperature, high pressure and high strain rate lasting for very short time (10-6 s) will cause a series of catastrophic changes of chemical and physical properties of materials. In our study, high velocity impact was used to apply shock wave loading and to produce high temperature and high pressure to obtain shock-induced nitrogen-doped titania and Ti-Si intermetallics. The photocatalytic degradation to rhodamine B of the TiO2 samples after doping with dicyandiamide was enhanced due to the higher N doping concentration and wider response to visible light. For the Ti-Si system, it is found that TiSi2 is formed under impact loading and exhibits certain photocatalytic activity of splitting water into hydrogen. Consequently, Ti5Si3 synthesized under impact loading has much better photocatalytic activity of splitting water into hydrogen than that of TiSi2 synthesized under impact loading at identical condition. The coupled photocatalyst of Ti5Si3 and Ti8O15 were dynamically synthesized by adding oxidant of NH4ClO4(wt.5%) and exhibits superior photocatalytic activity. In summary, by means of mechanochemical method with the shock treatment, our lab is trying to find out some new photocatalysts with high catalytic activities and reproduce it on a large scale for possible industrialization in the environmental remediation and green energy.

E-mail: jjlee@usc.edu. Fax: 213-740-8399 Abstract: Tsunamis waves caused by submarine earthquake or landslide might contain large wave energy which could cause significant human loss and property damage locally as well as in distant regions. The response of three harbors located at the Pacific coast (i.e. Crescent City Harbor, Los Angeles/Long Beach Port, and San Diego Harbor) to six well-known tsunamis events generated (both near-field and far-field) between 2005 and 2011 are examined and simulated using a hybrid finite element numerical model in frequency domain. The computed responses including the resonant periods and modes of oscillation for these three harbors are in good agreement with the energy spectral analysis of the time series of water surface elevations recorded at tide gauge stations during the six tsunamis events. The computed wave induced currents based on the present model are also in qualitative agreement with some of the reported eyewitness accounts. The simulated results show that each harbor responded differently and could significantly amplify certain wave period(s) of incident wave trains according to the shape, topography, characteristic dimensions and water depth of the harbor basins. The results of the present study could be used by environmental planners to derive emergency response plans to mitigate potential hazards. Estimation of Methane Emissions from California Natural Gas Industry Jeff Kuo*, Travis Hicks, Tat Fu Chan, and Brian Drake Dept. of Civil and Environmental Engineering, California State University, Fullerton 800 N. State College Blvd., Fullerton, CA 92831, USA e-mail: jkuo@fullerton.edu, Tel: +1-6572783995, Fax: +1-6572783916 Abstract: The California Global Warming Solutions Act of 2006 (AB 32) established a comprehensive program of regulatory and market mechanisms to achieve real, cost-effective, quantifiable reductions of greenhouse gases (GHGs). The Public Interest Energy Research (PIER) Program of California Energy Commission (CEC) has been funding climate change research since 2001 to study options available to reduce GHG emissions in California. The objective of the project was to produce current, reliable, and California-specific methane fugitive emission factors, which can then be used to establish a more accurate methane emission inventory for the California natural gas industry. The results from this project would be used to support regulatory programs to achieve effective and efficient methane emission reductions from California’s natural gas system, and, consequently, minimize adverse environmental impacts from these emission sources. The research team screened equipment and systems in all five segments of California gas industry (production, processing, storage, transmission, and distribution). Equipment/systems screened included 172 wellheads, 131 separators, 17 dehydrators, 145 piping segments, 66 compressors (51 reciprocating, 9 centrifugal, 6 rotary), 374 pneumatic devices, 19 metering and regulating stations, 34 hatches, 2 pumps, and 12 customer meters. Components screened on the equipment consisted of 10,101 flanges, 10,765 manual valves, 384 open-ended lines, 358 pressure relief valves, 930 regulators, 146 seals, 57,061 threaded connections, 12,274 welded connections, and 138 “others”. Using the data generated from field activities during this study, three types (average, screening ranges, correlation) of component-level emission factors were developed, when appropriate. These component-level emission factors were then used to develop equipment-level average emission factors, when appropriate.

Management of energy consumption and sludge disposal from WWTPs is of great importance, which was related to the economic and environmental benefits of the plants. This paper presented the basic situation of energy consumption in China based on the data from 1856 plants in 2009 and discussed the impact of different factors including scales and operation rate on the energy consumption. The analysis of the result showed that average energy consumption of 1856 WWTPs in China in 2009 was 0.254 kWh/m3. The energy consumption in WWTPs decreased with the increase of scale and operation load rate. A typical WWTP in North China was selected as the case study to analyze the operation of different energy related unit, concluding that aeration was an important part and took more than a half of the total energy consumption. Meanwhile, it’s of great importance not only to analysis the energy consumption, but also to simulate the excess sludge production. A model was established to simulate the discharge of excess sludge in the wastewater treatment plants based on the data of 696 plants in China in 2009. Indicators including temperature, influent, COD, SS and TN were considered in the model. Indicator factors were calculated based on four main treatment process including AnaerobicAnoxic-Oxic Process (A2O), oxidation ditch process, Sequencing Batch Reactor Activated Sludge Process (SBR) and traditional activated sludge process. Comparison of the original values and simulation results showed that the model could simulate the situation of excess sludge discharge quite well. The model application in a typical plant in South China was conducted, illustrating that it could reflect the operation of excess sludge discharge basically. However, simulation results in August and September were not so accurate due to the reduction of influent BOD and biodegradable ability, leading to the relatively lower sludge production. The model could be developed more comprehensively in the future. With the accuracy and convenience of the model, it could be widely used in the control and disposal of sewage sludge from different treatment processes. The result could be used to guide the operation of WWTP with lower energy consumption and sludge discharge.

The most significant impacts range from approximately 20 feet below ground surface (ft bgs) to 40 ft bgs in a sandy soil, above a clay aquitard. The site is located on a hill top with frequent high speed winds. A bioventing pilot study was conducted to evaluate the effectiveness of chemicals of concern (COC) removal and collect parameters for full-scale design and implementation. The pilot study indicated that bioventing would be effective to remove COC with a promising 77-foot radius of influence, air permeability of 42 Darcy, and oxygen utilization rate of 9.4% per day at injection pressure of 0.7 psi and air flow of 70 scfm. To evaluate the potential to use wind-driven bioventing technology, two mobile weather stations were installed at the site and monitored for one month. Collected wind speed was shown to have 97% correlation with a local public weather station which was used to predict the wind speed at the site on an annual basis. Based on the pilot test data and wind speed research, 12-inch diameter funnel/vane 360o wind collectors with check valves and monitoring ports were designed as passive wind-driven air injection devices. After three months of system operation, oxygen delivery increased to 20%, carbon dioxide decreased from 5% to 0%, and hydrocarbon concentrations were reduced by 80% to 90%. The benefits of the green bioventing system included an estimated reduction in electricity consumption by approximately 20,000 kWh per year and elimination of air pollutants and greenhouse emissions. Environmental Performance Evaluation of Beijing’s Energy Use Planning Linyu Xu, School of Environment, Beijing Normal University Abstract: In line with rapid economic development, urban energy consumption is increasing rapidly, resulting in environmental problems. After considering several methods to evaluate the environmental performance of energy use, including: energy ecological footprint, input–output analysis, emergy–exergy analysis, and multi-criteria decision-making, an environmental performance evaluation model is proposed, which combines the analytical hierarchy process, fuzzy extent analysis, and membership degree analysis. In the model, 18 sub-indicators of environmental performance from energy use planning are classified into four categories: structure of energy use and industry, technology and efficiency of energy use, environmental impacts caused by energy use, and the socio-economic benefits of energy use. Membership degree analysis is applied to each indicator. Three energy use scenarios which are, respectively, environment-friendly, technology-led, and economic policy-led are evaluated. The results show that the technology-led energy use planning is best. The sustainable energy use policies are proposed from three aspects, including optimizing the energy use and industrial structure, encouraging development of energy-saving and air pollution control technologies, and enhancing legislation on energy use management. The policies are helpful to optimize the trade-offs between economic growth and environmental protection in Beijing. TECHNICAL SESSION 6A Wastewater and Solid Waste Management Moderators: Michael E.

Dewatering of Sewage Sludge Conditioning with Skeleton Builders Jiakuan Yanga, Fei Shia, Yalin Lia, Huan Liua, Wei Maoa, Hao Zhanga, Xin Xua, Ye Lib, Shu Heb, Wenbo Yua, Shinan Zhanga a School of Environmental Science and Engineering, Huazhong University of Science and Technology, Wuhan, Hubei, 430074, P.R.China b Universtar Science & Technology (Shenzhen) Co., Ltd., Shenzhen, Guangdong, 518057, P.R.China Abstract: Dewatering of sewage sludge is a bottle-neck in the sewage sludge treatment and disposal since sewage sludge has higher content of organic matter and moisture. Chemical conditioner is usually used before sewage sludge is dewatered, and polymer conditioner, i.e. PAM, is most commonly used, followed by the mechanic dewatering process. However, such conditionally dewatered sludge cake is still with a high water content of about 75-85 wt%, which has a negatively effect on the following sludge disposal or incineration. In this paper, physical conditioners, often known as skeleton builders, are used to improve the dewaterability of sewage sludge. Three types of composite conditioners comprising skeleton builders are studied, i.e. ferric salt combined with skeleton builders, Fenton’s reagent combined with skeleton builders, cationic surfactants combined with skeleton builders. The several evaluation indexes were used to evaluate the dewaterability of sewage sludge conditioned with composite conditioners, i.e. specific resistance to filtration (SRF), capillary suction time (CST), and dewatering efficiency. The results show that composite conditioners comprised skeleton builders can sufficiently improve the dewaterability. Key words: Sewage sludge, dewatering of sludge, skeleton builder, specific resistance to filtration (SRF) An Innovative Adsorption/Nitrification/Denitrification/Sludge-Hydrolysis Wastewater Treatment Process (Andh) for Wastewater Treatment Xianghua WEN, Ph.D Department of Environmental Engineering, Environmental School, Tsinghua University Abstract: An innovative adsorption/nitrification/denitrification/sludge-hydrolysis wastewater treatment process (ANDH) characterized by carbon source manipulation with a biological adsorption unit and a sludge hydrolysis unit was developed to enhance nitrogen removal and reduce sludge production for municipal wastewater treatment. The system presented good performance in pollutants removal, yielding the effluent with average COD, NH4-N, TN and TP of 48.5, 0.6, 13.2 and 1.0 mg/L, respectively. Sixty percent of the total carbon source in the influent was concentrated and separated by the quick adsorption of activated sludge, providing the possibilities of reusing waste carbon source in the denitrification tank and accumulating nitrobacteria in the nitrification tank. Low temperature of 6–15C and high hydraulic loading rate of 3.0–15.0 m3/d did not affect NH4-N removal performance, yielding the NH4-N of lower 1.0 mg/L in the effluent. Furthermore, 50% of the residual sludge in the ENRS system could be transformed into soluble COD (SCOD) by alkaline thermal hydrolysis with temperature of 60C and pH of 11, and the hydrolyzed carbon could completely substitute methanol as a good quality carbon to support high efficient denitrification. The microbial communities in the different functional units as showed by the results of clone library, terminal restriction fragment length polymorphism (T-RFLP) and 454 sequencing tools were apparently different, such as the content of Proteobacteria in absorption tank, nitrification tank and denitrification tank were 29.41%, 14.16, and 29.53% respectively. Each tank had a microbial structure which was different from the others. Stabilization of Fly Ash from Municipal Solid Waste Incinerators Utilizing Landfill Leachate Yanyu Wu, Xiaoying Hu, Xiaochun Peng South China Institute of Environmental Science, MEP, Guangzhou, 510655 Abstract: Synergistic co-disposal of concentrated leachate rejected from reverse osmosis (RO) and fly ash from municipal solid waste incinerators were investigated. Batch tests were carried out by agitating suspension fly ash with certain concentrated leachate without pH adjustment, and then the mixture was placed in an incubation vessel for setting incubation time. Scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis, X-ray fluorescence technique (XRF), low temperature N2 adsorption-desorption (BET) were used for the characterization of fly ash before and after incubation. The results showed that there were obvious changes in microstructures and crystalline phases before and after stabilization. Ca(OH)2 disappeared with the appearance of CaCO3. Moreover, phosphate crystal, sulfide deposits and hydroxide precipitation of heavy metals occurred after incubation. The experimental results suggested that the immobilization mechanism for heavy metals was mainly deposits precipitation and surface adsorption. The toxicity characteristic leaching procedure (TCLP) test revealed that almost all of heavy metals could be stabilized through landfill leachate treatment. The leaching concentration of the critical heavy metals decreased 35%-60% after incubation. When the incubation time was longer than 7 d, the leaching concentration of critical heavy metals decreased insignificantly. The pH of incubation system reduced from 12.67 to 11.32. In addition, as the main organic pollutants in landfill leachate, humic acids isolated from incubation system decreased over 75% indicated that the carbonation occurred while incubation. Moreover, surface adsorption also played an important role on the disappearance of pollutants in landfill leachate. Overall, due to the presence of landfill leachate along with fly ash in the synergistic co-disposal, the results presented herein can be applied to the management of fly ash and landfill leachate simultaneously. Keywords: Synergistic co-disposal, fly ash, landfill leachate, stabilization TECHNICAL SESSION 6B Environmental Corporation Case Study Water Reuse and Desalination Qingshan Wang, Senior Design Manager and Operational Lead CHM2 Hill Abstract: Water reuse, the practice of using water that has been used, is currently considered a key component of water supply portfolio in California and some other part of the county. The importance of efficiently using existing water supplies is becoming increasingly evident as sources of new supply become more difficult to acquire. Water reuse, the practice of taking water that has already been used and using it again for a beneficial purpose, is a key component of the state’s water supply portfolio. Typically this practice uses reclaimed water (or reclaimed wastewater), which is domestic or municipal wastewater that has been treated to a quality that makes it suitable for a beneficial use. When talking about water reuse, it is important to make the distinction between direct reuse and indirect reuse. Water reuse is safe, sustainable, cost effective approach to deal with water scarcity. Desalination: Desalting refers to a water treatment process that removes salts from water. Desalting technologies can be used for a number of applications. Desalination is an integrated part of water management portfolio. The underlying market driver is water scarcity and this continues to grow. In most parts of the world the cost of desalinated water is greater than the price charged to consumers. This means that the growth of the market is limited by the availability of subsidies. The long term outlook for the desalination industry is strong. Most of the desalination plants in the US utilize membrane processes for desalting brackish water. However there are several large seawater plants in the planning phase. Air Quality, Climate Change, and Clean Truck Program Eddy Huang, Ph.D. Air Quality Director Tetra Tech, Inc. Abstract: Confronting the threat of global climate change is a challenge that will reorder priorities for decades to come. It will require a long-term vision and the discipline to make critical public and private investments in renewable energy, infrastructure, and environmental technology. Reducing carbon footprint will bring multiple environmental benefits, with cleaner air, better public health, and more open space. This presentation covers Tetra Tech’s experience in managing and implementing large-scale air quality and climate change projects. A prime example is the San Pedro Bay Ports Clean Truck Program (CTP). This is a large-scale, multi-year air quality improvement project by enforcing a truck ban and replacing higher-polluting older trucks with cleaner, newer models. The CTP is very complex; it involves the San Pedro Bay Ports, trucking communities, terminal operators, cargo owners, and regulatory agencies. Some of the key elements of the CTP include: Grant application, administration and management Truck registration and updates Terminal truck gate move analysis Outreach to trucking communities Alternative fuel vehicles Special truck moves analysis and projections to support policy-making Coordination with regulatory agency to implement truck ban Help line support to trucking companies and drivers Ports’ Drayage Truck Registry (PDTR) support Groundwater Impacts and Fate Transport Modeling of Perchlorate Stringfellow Superfund Site, Riverside County, CA Jim Fingan, Ph.D. CHg, Principal Hydrogeologist Kleinfelder Abstract: The Stringfellow Superfund Site in Riverside, California, overlies an aquifer system comprising alluvium, weathered bedrock, and unweathered bedrock. Groundwater impacts from aerospace and other wastes include trichloroethene and other organic compounds, acidic conditions, and various inorganic compounds including perchlorate. Perchlorate impacts to groundwater extend approximately 5 miles downgradient from a box canyon containing the source area through an alluvial paleovalley towards the Santa Ana River. A three-dimensional numerical model of groundwater flow and perchlorate transport in this system downgradient of the source area was developed in 2003 and has subsequently been updated and refined to provide predictions of solute transport and evaluation of remedial alternatives. Following completion of a Remedial Investigation and subsequent investigations, substantial refinement of the model was performed, providing more realistic parameter inputs and enabling more accurate predictions of perchlorate transport. Existing remedial systems installed to control the migration of volatile organic compounds comprise pump-and-treat extraction wells along the plume path. Following detection of perchlorate in 2001, remedial investigations have focused on control of this compound, although additional perchlorate sources (e.g., Chilean fertilizer and quarry blasting chemicals) besides the Stringfellow Site have also been identified as impacting regional groundwater. The numerical model has been used to test several remedial alternatives in support of the site feasibility study, including no action, continuing current pump-and-treat remediation, modifying existing pump-and-treat systems, and in-situ bioremediation. However, because there are additional ambient sources of perchlorate, setting a cleanup goal included statistical evaluation of ambient concentrations and establishing zones of separation of the comingled plumes. The numerical model was therefore used to evaluate cleanup times to both prescriptive and statistically based goals. Predicted cleanup times for perchlorate to the different cleanup levels range from 11 to over 100 years. The numerical model has also been used to support a technical impracticability evaluation for remediating groundwater impacts in unweathered bedrock and is expected to serve as a tool for other ongoing and future site investigations. 專題會議日程 第五屆全球當前環境挑戰與 第五屆全球當前環境挑戰與政府 當前環境挑戰與政府應 政府應對措施研討會 對措施研討會 專題會議和培訓講座 主辦單位: 主辦單位:美國南加州華人環保協會 美國南加州華人環保協會 (SCCAEPA) 污染場地修復和綜合管理 時間: 時間:2012年 2012年8月13 - 16日 16日 地點: 地點: 洛杉磯聖 洛杉磯聖蓋博希爾頓大酒店 請登陸協會網站: 請登陸協會網站:www.sccaepa.org 美國南加州華人環保協會(SCCAEPA)將與2012年8月13日至16日舉辦題為“污染場地修復和綜合管 理”的專題會議和培訓講座。協會將邀請美國政府官員,專家,學者就土壤與地下水污染場地評估, 清理和檢测的綜合管理等相關題目做專題報告,並組織實地現場參觀洛杉磯地區污染場地清理項目, 污染地下水處理等設施。所有講座將使用中文講解。 講座主要內容: 講座主要內容 1. 美國及加州有關污染場地管理的法律法規及執行細則和監管架構 2. 污染場地調查及管理程序 3. 土壤與地下水污染清理技術及預期效果 4. 污染土壤的處理要求 5. 綠色清理技術在污染場地治理中的應用 6. 新技術在污染場地調查和清理中的應用(納米技術,環境痕跡學,等) 7. 美國加州土壤與地下水清理目標的確定及相關標準 8. “超級基金”和“棕色場地”項目管理 9. 污染場地清理中的許可證管理及受污染土壤的處理要求 10.污染場地風險評估和結案標準 11.污染場地清理的市場機制和檢測數據認證 12.污染場地數據庫管理(GeoTracker,EnviroStor) 13.污染場地清理案例分析 14.加州室內毒氣入侵風險評估和執法 現場參觀路線: 現場參觀路線: 土壤污染修復場地;原位修復場地; 地下儲油罐污染場地修復工程; 大型地下水井口污染處理設施; 注冊費 : 每人每天$100 每人每天$100( 100(注册费包括資料, 注册费包括資料,午晚餐, 午晚餐,參觀交通等) 有關報名登記事宜, 請洽王光宇博士 (Dr. Guangyu Wang) 電話: (213) 576-6639 電子郵件:gwang@waterboards.ca.gov 請在我會網站下載報名表,填表後請寄: sccaepa2011@gmail.com 1 報告講座 專題講座日程 8月 月 13 日 (9:00 am —12:00 pm) 上午 1. 中國土壤與地下水污染防治規劃概述(吳舜澤副院長,中國環保部環境規劃院)( (9:00 —10:00 am) 2. 美國及加州有關污染場地管理的法律法規及執行細則和監管架構(童衛星博士)( (10:00 —10:50 am) a. 美國聯邦政府有關污染場地管理的法律法規 b. 加州政府有關污染場地管理的法律法規 c. 美國污染場地管理的政府架構設置和責任劃分 d. 各級政府有關土壤和地下水污染預防的相關規定和措施 2. 污染場地調查及管理程序 (童衛星博士) a. 土壤與地下水污染物分類 b. 場地污染項目分類 c. 地下儲油罐污染預防與清理管理程序 d. 其它類型污染場地管理程序 3. 污染場地清理中的許可證管理 (吳基銜博士)( (11:10 am —12:00 pm) a. 法規要求 b. 許可證類別 c. 許可證要求 d. 檢測及報告 e. 達標認證 下午 (2:00 —5:30 pm) 1. 土壤與地下水污染清理技術及預期效果 (容 躍博士) (2:00 — 3:50 pm) a. b. 2. 土壤與地下水污染清理技術综述, • 挖掘土壤(soil excavation) • 土壤氣相抽吸法 (soil vapor extraction) • 電阻和燃氣加熱法 (electrical resistance heating, gas heating) • 地下水抽吸加處理(groundwater pump and treat) • 原位化學和生物注射法(in-situ chemical and biological injection) • 檢測自然衰减法( monitoring natural attenuation) 土壤與地下水污染清理技術的優缺點評估 美國加州土壤與地下水清理目標的確定及相關標準 (容 躍博士) a. 有機污染物在土壤和地下水中的遷移轉化 b. 污染物對人類健康風險評估 c. 土壤與地下水清理目標的决定 d. 加州政府水質管理總局理事會新頒”地下儲油罐系统低風險結案政策”(2012) 2 報告講座 3. 專題會議日程 土壤廢氣抽吸法和水洗法設計與施工要素及實例分析 (郭繼汾博士)( (4:10 — 5:30 pm) 8月 月14日 日 上午 (9:00 am —12:00 pm) (9:00 —10:20 am) 1. 綠色清理技術在污染場地治理中的應用 (張寧武博士)( a. 綠色清理之起源 b. 綠色清理之原則與應用 c. 綠色清理之實例 2. 污染場地風險評估和結案標準 (鄭傳贏博士)( (10:40 am —12:00 pm) a. 簡介 b. 風險評估概述 –風險評估的歷史和要素 c. 風險評估的作用和場地清理的結案標準 d. 案例分析 / 典型項目 e. 結論 下午 (2:00 —5:30 pm) 新技術在污染場地調查和清理中的應用(納米技術,環境痕跡學,等) 1. 利用零價鐵對受污染地下水和土壤的修復 (熊忠博士)( (2:00 —3:00 pm) a. 零價鐵用於污染場地修復的介紹 b. 利用納米零價鐵修復受污染地下水和土壤的工程案例 c. 利用零價鐵-可滲透性反應牆修復受污染地下水的工程案例 2. 石化碳氫化合物痕跡學 — 原理和案例分析(盧軍博士)( (3:00 —4:00 pm) a. 爲什麽要使用痕跡學? ♦ ♦ ♦ b. 法律層面 環境層面 污染物洩漏檢測 痕跡學原理 ♦ c. 石油成因 ♦ 石油提煉 ♦ 環境變異 ♦ 混合與融合 案例分析 ♦ 污染物洩漏影響區的圈定 3 報告講座 專題會議日程 ♦ ♦ 3. 洩漏污染物的時間區分(過去和現在的洩漏區分) 混合的“輕非溶水性液體”污染暈區分 “超級基金”和“棕色場地”項目管理 (胡桂君 高級工程師)( (4:30 — 5:30 pm) a. “棕色場地”定義和法律依據 b. 加州“棕色場地”的分類和概況 c. 加州“棕色場地”的管理架構和管理程序 d. 加州“棕色場地”管理中面臨的挑戰 e. 聯邦環保署“超級基金”項目在加州的執行與管理 8月 月16日 日 上午 (9:00 am —12:00 pm) 1. 美國聯邦環保署“超級基金”項目管理經驗介紹(譚思理 主任)( (9:00 — 9:50 am) a. 歷程:超級基金的緣起 b. 法定權限:超級基金如何發揮作用? c. 成就:超級基金取得的成果 d. 融資:“超級”基金是什麽? e. 各州的融資機制 f. “超級基金”項目的特色 2. 受污染土壤在垃圾填埋場的處理和利用 (楊文博士)( (9:50 —10:40 pm) a. 垃圾填埋場的種類, 建造標準, 和日常營運 b. 垃圾填埋場的執法管理 c. 受污染土壤再生利用的標準 d. 與受污染土壤再生利用有關的防污染措施 3. 污染場地數據庫管理(童衛星博士,楊文博士) (11:10 —12:00 pm) a.

Environmental Protection Association COMMONLY USED ENVIRONMENTAL THRESHOLDS (Dr. Wen Yang / SCCAEPA Life Member) Total Threshold Limit Concentration (TTLC) and Soluble Threshold Limit Concentration (STLC) and Solid Waste Classification: TTLC and STLC are used to determine the toxicity of a waste as outlined in Title 22 of the California Code of Regulations. TTLC determines the total concentration of each analyte in a sample, while STLC determines the amount of each analyte that is soluble in the Waste Extraction Test (WET) leachate. When any target analyte exceeds the TTLC limits, the waste is classified as hazardous. If the TTLC results do not exceed 10 times the STLC limit, then normally no further analysis is required. Otherwise, the waste must be analyzed for STLC. In the WET leachate procedure a sample of the waste is tumbled in 10 times its weight of a 0.2M sodium citrate solution for 48 hours. This leachate is then analyzed to determine the soluble concentrations. The waste is classified as hazardous if the concentration of any target analyte in the leachate exceeds its STLC. (Web link: http://www.excelchem.net/Documents/STLC.doc) California Proposition 65: Proposition 65, formally titled The Safe Drinking Water and Toxic Enforcement Act of 1986, is a California law enacted as a ballot initiative in November 1986. Its goals are to protect drinking water sources from toxic substances that cause cancer and birth defects and to reduce or eliminate exposures to those chemicals by requiring warnings in advance of those exposures. Proposition 65 prohibits businesses from knowingly discharging listed substances into drinking water sources, or onto land where the substances can pass into drinking water sources. It also prohibits businesses from knowingly exposing individuals to listed substances without providing a clear and reasonable warning. (Web link: http://oehha.ca.gov/prop65/prop65_list/files/p65single072012.pdf) Public Health Goals (PHGs): PHGs are concentrations of contaminants in drinking water that pose no significant health risk if consumed for a lifetime, based on current risk assessment principles, practices, and methods. The Office of Environmental Health Hazard Assessment (OEHHA) of California Environmental Protection Agency (CalEPA) establishes PHGs pursuant to California Health & Safety Code §116365(c) for contaminants with maximum contamination levels (MCLs), and for those for which California Department of Public Health (CDPH) will be adopting MCLs. Once OEHHA establishes or revises a PHG for a contaminant, CDPH determines whether the MCL of the contaminant should be revised. (Web link: http://oehha.ca.gov/water/phg/allphgs.html) Regional Screening Levels (RSLs): RSLs (formerly Preliminary Remediation Goals or PRGs) are developed by the United States Environmental Protection Agency for the remediation of chemical contaminants at Superfund sites. They are used for site screening and as initial cleanup goals, if applicable. Generally, at sites where contaminant concentrations fall below RSLs, no further action or study is warranted under the Superfund program as long as the exposure assumptions at a site match those taken into account by the RSL calculations. Contaminant concentrations above the RSL would not automatically designate a site as "dirty" or trigger a response action; however, exceeding a RSL suggests that further evaluation of the potential risks by the contaminants is appropriate. (Web link: http://www.epa.gov/region9/superfund/prg/) California Human Health Screening Levels (CHHSLs): CHHSLs are concentrations of 54 hazardous chemicals in soil or soil gas that the Cal/EPA considers to be below thresholds of concern for risks to human health. The thresholds of concern used to develop the CHHSLs are an excess lifetime cancer risk of one-in-amillion and a hazard quotient of 1.0 for noncancerous health effects. Under most circumstances, the presence of a chemical in soil, soil gas or indoor air at concentrations below the corresponding CHHSLs can be assumed to not pose a significant health risk to people who may live (residential CHHSLs) or work (commercial/industrial CHHSLs) at the site. The presence of a chemical at concentrations in excess of a CHHSL does not necessarily indicate that adverse impacts to human health are occurring or will occur, but suggests that further evaluation of potential human health concerns is warranted.
