Calendar year 2010 was a banner year for OST, continuing its efforts from 2009 with greater collaboration among partners and stakeholders to ensure that sound science and the latest technologies guide the work of EPA’s water programs. OST published the Guidance for Implementing the January2001 Math ylmercury Water Quality Criterion, completing nearly a decade of work in this area. OST also issued several important rulemakings, reports and recommendations for numeric nutrient criteria: the proposed and final rules for numeric nutrient criteria for Florida’s lakes and flowing waters, as well as guidance for states using a stressor- response approach to derive nutrient criteria. In addition, OST began the process of revising the current Water Quality Standards regulation which has been in place almost 30 years. 2010 also marked the completion of a precedent-setting science and research initiative by OST and the Office of Research and Development that will support development of improved recreational water quality criteria in 2012. In 2011, OST will continue making great strides, including a proposal of Water Quality Standards regulatory revisions; rulemakings on numeric nutrient criteria for Florida estuaries and coastal waters, post-construction stormwater discharges, airport deicing discharges, dental amalgam discharges; and standards to minimize impacts from cooling water intakes. OST will also issue guidance for managing unused pharmaceuticals at health care facilities, and will partner with the Office of Pesticide Programs to complete peer-reviewed methodologies to assess the effects of pesticides on aquatic life. The great work OST has accomplished in 2010 reflects its exceptional, diverse and creative staff. Whether addressing policy issues, water-quality research or technological innovation, OST’s staff assures that the nation’s water programs are built on an advanced and reliable scientific foundation. Given this highly motivated staff and its talented and experienced management team, I am confident that we will effectively meet whatever environmental challenges we may face in 2011. Ep4rth t S Director, Office of Science and Technology ( 1 . ., p J ------- Wkat We 1ô OST uses sound science, engineering and public policy to protect and restore the nation’s water quality. OST ensures thatfederal and state water programs reflect current scientific knowledge about water pollution causes and impacts on human health and ecosystems. Under the Clean Water and Safe Drinking Water Acts, OST advances public health and environmental protection by producing technology guidelines for industrial discharges and cooling water intakes; analytical test methods; water quality standards (WUS); water quality criteria recommendations; models and tools; guidance for advisories for beach swimming, fish consumption and drinking water; and risk assessments and special studies identifying needed regulations. SUPPORT AGENCY GOALS AND ADMINISTRATOR PRIORITIES Because OST’s work supports a variety of offices and programs, our efforts align with several of the Agency’s strategic goals: Clean and Safe Water, Healthy Communities and Ecosystems, and Compliance and Environmental Stewardship.

OST supports the National Pollutant Discharge Elimination System (NPDES) permit program by providing technology-based standards for industrial and municipal dischargers. OST’s analytical methods program supports monitoring and compliance for permit writers and other water programs. OST also provides guidance to states on developing and implementing fish consumption advisories, assists in promoting state advice to consumers and develops federal fish advisories with the Food and Drug Administration when necessary. In addition, OST develops drinking water health advisories to support EPA regional offices, state governments and other public health officials. These advisories are guidance values based on non-cancer health effects for different durations of exposure to certain drinking water contaminants. •/ z .- -; ; i ’ •r __, . - ------- ‘ C C.) • Treatment Effectiveness Report for Contaminants of Emerging Concern—EPA published the results of an extensive literature review on wastewater treatment technologies and their ability to remove contaminants of emerging concern. • Methods Update Proposed Rule—EPA proposed a methods update rule to approve new or revised test procedures for wastewater regulations. These changes increase the regulated community’s and laboratories’ flexibility in ( ) o v) selecting analytical methods for use in Clean Water Act programs. • Final Mercury Criteria Implementation Guidance—EPA published Guidance for implementing the January2001 Methylmercury Water Quality Criterion to protect waters and human health by giving guidance for adopting a fish tissue- based methylmercury water quality criterion into water quality standards and implementing the criterion through other water quality programs. • Federal Nutrient Criteria for Florida’s Lakes and Flowing Waters—EPA promulgated landmark numeric nutrient criteria for Florida’s lakes and flowing waters. This rulemaking is the first of a two rulemakings to establish numeric nutrient criteria for waters throughout the state. • BEACH Act Grants—EPA implemented a supplemental formula for the BEACH grant allocation, which considers the total number of beach miles, beach use and grant expenditures, to provide an incentive for more timely expenditure of grant funds. The Agency awarded almost $10 million to eligible state, territorial and tribal governments in 2010. EPA also published its 2011 BEACH Act grants solicitation notice in the Federal Register. • Water Quality Standards Regulatory Revisions—OST began revising the . . ‘f ’ current Water Quality Standards regulation, which has been in place since 1983. EPA held a series of listening sessions to inform the public and state, ‘ ,‘ 1 tribal and local governments about the potential changes. EPA will consider the “—. comments received as it develops the proposed rulemaking. ( . • Fluoride Risk Assessment—EPA completed and peer reviewed documents on environmental exposure of children and adults to fluoride and water’s contribution to fluoride exposure. • Recreational Water Quality Criteria Research—OST worked with the Office of Research and Development to coordinate and complete critical science and ,. research that will be used to develop new or revised recreational water quality criteria by October 2012. • Mississippi Delta Fish Advisory—EPA completed the report of the Survey on the Awareness and Effectiveness of the Mississippi Delta Fish Advisory, which focused on recreational and subsistence fishers in the Mississippi Delta. 0• ------- 1 - , 1 ; ‘ (_, - •: ‘• - - t Y ! ’ I ‘ p /‘J _• 3 - r ‘ - •‘ . - A q [ 41 -1 p REVISED REGULATIONS FOR STEAM ELECTRIC POWER GENERATING H In 2009, EPA started a rulemaking to revise the effluent guidelines for Steam Electric Power Generating, which were originally issued in 1982. These standards apply to steam electric power plants using nuclear or fossil fuels. EPA continued its efforts in 2010 by substantially expanding and improving the knowledge and understanding of the pollutant discharges and strategies for reducing those discharges. Facilities that generate steam electric power were asked to respond to an EPA questionnaire. More than 700 facilities responded, providing detailed information about operational characteristics and financial conditions. In addition, OST collected wastewater samples at ten plants. Chemical analysis of the samples, combined with engineering assessments of the plant’s operations, will form the basis of regulatory options. The Agency will propose new guidelines in mid-2012 and complete the rule in early 2014. For more information, please visit i p’ Wa(e1.epa.guv. cI1ecfIvvd Lb’wt;I. yu;dt’ . Li:1I uiu&x.crm. STORMWATER RULE ADDRESSING POST-CONSTRUCTION DISCHARGES EPA initiated a national rulemaking to establish a program reducing stormwater discharges from new development and redevelopment and making other regulatory improvements to strengthen the stormwater program. EPA developed and distributed a questionnaire in 2010 to collect data that will provide EPA with information it needs to establish the program: • Current building, transportation and real estate improvement projects. • Long-term stormwater controls and best management practices being installed at newly developed and redeveloped projects. • State and local long-term stormwater programs and requirements and the areas covered by these programs. • Current capacity and expenditures by NPDES Permitting Authorities and local authorities to implement, enforce and maintain long-term stormwater programs and controls. • Technical financial and environmental data needed to quantify the incremental pollutant removals, compliance Costs, impacts and benefits for various regulatory options that EPA might consider in this rulemaking. Stakeholder outreach was a priority during 2010. During six listening sessions in cities across the country and a widely-attended webcast, EPA received public comment on various approaches to regulating stormwater discharges. r 4 ‘1• ------- (2i EPA will propose a rule for public comment in Fiscal Year 2011. For more information, please visit TREATMENT EFFECTIVENESS REPORT FOR CONTAMINANTS OF EMERGING CONCERN In August 2010, OST posted the results of an extensive review of the recent literature on wastewater treatment technologies and their ability to remove contaminants of emerging concern (CEC). EPA also made the data from this review available in a searchable form. This information was developed to provide an accessible and comprehensive body of historical information about current CEC treatment technologies. The report was not designed to promote any one technology, nor is it intended to set Agency policy or priorities in terms of risk. The literature review report and searchable file can be found at 4 ’ h f-tn ’ i i tpr gnv/c’.. ItPrh/sLIvguidance/ppcp/resultc í’frn GUIDANCE ON MANAGING UNUSED PHARMACEUTICALS In September 2010, EPA announced the availability of a draft guidance document on best management practices for unused pharmaceuticals at health care facilities. OST’s study of unused pharmaceutical management practices at health care facilities was prompted by the concern that large amounts of pharmaceuticals are being disposed of improperly, polluting rivers, streams and coastal waters. The draft guidance document describes techniques for reducing or avoiding pharmaceutical waste, practices for identifying and managing types of unused pharmaceuticals, and applicable disposal regulations. EPA received extensive comments on the draft document. Following a careful review of those comments, EPA will issue the guidance document in final form in mid-2011. For more information, please visit METHODS UPDATE PROPOSED Ru1.E In July 2010, EPA proposed a methods update rule to approve several new or revised test procedures for wastewater regulations. EPA is proposing to add new and revised methods published by the Agency, voluntary consensus organizations (e.g., ASTM, International and the Standard Methods Committee) and commercial entities for use in water quality monitoring programs. These changes and additional methods will provide increased flexibility to the regulated community and laboratories in their selection of analytical methods for use in CWA programs. EPA approves analytical methods for measuring regulated pollutants in wastewater. The regulated community and laboratories use these approved methods for determining compliance with NPDES permits or other monitoring requirements. Often, these entities have a choice in deciding which approved method they will use to measure a pollutant because more than one approved method is available. This rule proposes to add to this list of approved methods, including introducing new technologies and updated versions of previously approved methods.

WATER QUALITY STANDARDS PROGRAM Water Quality Standards (WQS) are the foundation of the water quality- based control program mandated by the CWA. Defining goals for U.S. waters and setting the standards against which all other surface water quality programs measure success, WUS consist of four elements: • Designated uses for water bodies, such as recreation, aquatic life support, public water supply and agriculture. • Water quality criteria that establish numeric pollutant concentrations or narrative descriptions of water conditions that must be met to attain designated uses. • Antidegradation policy to maintain and protect existing uses and high-quality waters. • Other policies that address the implementation of standards. Through its Water Quality Standards Program, OST develops the recommended criteria and reviews the state standards that protect and restore the nation’s water bodies. States and territories lead the implementation and administration of WQS programs under the CWA. OST and EPA’s regional offices provide federal oversight for state and territorial programs, but all work together as co-regulators on a daily basis. Tribes may apply for federal authorization to administer WQS programs under the CWA. OST provides technical assistance to tribes in applying for federal program authorization and in developing and implementing WQS and other water quality programs. To date, 46 tribes have federal authority to administer a WQS program, 37 of which have EPA-approved, CWA-effective WQS. Regional and State Support for Water Quality Standards In addition to developing federal WQS regulations, national policy and guidance, OST supports regions and states on specific WQS actions. OST helps its regional counterparts review many state standards packages submitted to the regions for review and approval or disapproval. EPA approved more than 90 percent of the state submissions received in FY 2010. In addition, OST supported the states in their development of numeric nutrient criteria. EPA funded data gathering, provided experts to analyze data and recommended nutrient criteria values. EPA also published proposed and finalized numeric nutrient criteria for Florida’s lakes and flowing waters.

After careful consideration of the comments, the final rule was signed by Administrator Jackson on November 14, 2010 and published in the Federal Registeron December 6,2010. The final rule is accompanied by an extensive scientific supporting document that provides the scientific foundation r and justification for the final criteria values: Technical Support Document for U.S. EPA’s Final Rule for Numeric Criteria for Nitrogen/Phosphorus Pollution in Florida’s Inland Surface Fresh Waters. EPA deferred the promulgation of criteria for the south Florida inland flowing waters and the procedure to adjust stream criteria to protect downstream estuaries to November 2011, when EPA will propose numeric criteria for Florida’s estuaries and coastal waters. Estuarine, Coastal and Southern Inland Flowing Waters Rulemaking EPA also initiated a rulemaking for Florida’s estuarine, coastal and southern inland flowing waters in 2010. EPA developed the document, titled “Methods and Approaches for Deriving Numeric Criteria for Nitrogen/Phosphorus Pollution in Florida’s Estuaries, Coastal Waters and Southern Flowing Waters,” and submitted itto EPA’s Science Advisory Board (SAB) for review in November 2010. The document describes the approach EPA is considering for developing downstream protection values that may be applied to Florida streams to ensure the attainment and maintenance of downstream WQS. EPA provided additional information to the SAB at a public meeting in December 2010. The recommendations provided to EPA through the SAB review process will strengthen the scientific basis of numeric criteria for nutrient pollution to be proposed for Florida’s estuaries, coastal waters and southern inland flowing waters in November 2011. The final rule is scheduled to be signed in August 2012. Listening Sessions on WQS Regulatory Revision Considerations in 2010, OST began the process of revising the current WQS regulation, which has been in place since 1983. Potential revisions include strengthening protection for water bodies with water quality that already exceeds or meets the interim goals of the CWA; ensuring that standards reflect a continued commitment to these goals wherever attainable; improving transparency of regulatory decisions; and strengthening federal oversight. The proposed rule revising the current regulation is expected to be published in 2011. EPA has met with state, tribal and local governments; intergovernmental associations; environmental and industry groups; and private citizens to provide information and collect input regarding EPA’s proposed revisions to the water quality standards regulations. Pre-proposal outreach began mid- summer 2010 and continued through the fall, with EPA holding thirteen meetings with stakeholders. Two listening sessions were held for the general public and attracted many state and local government representatives. Two meetings were held specifically for tribal governments and three for state regulators. One session was held with intergovernmental associations, three with environmental groups and two with industry representatives.

MONITORING AND PUBUC INFORMATION OST’s beach program works in partnership with the EPA regions and state and local governments to protect water quality at U.S. beaches and the health of beach visitors. The beach program focuses on five areas: C a a ------- • Strengthening local beach WQS and monitoring efforts to enhance protection of public health at beaches. • Improving tools for monitoring and providing predictive tools and faster laboratory test methods for beach water samples. • Improving ways to identify causal sources and conditions. • Investing in human health and analytical methods research. • Informing the public of water quality monitoring and notification information about U.S. beaches. BEACH Act Grants To improve water quality testing and help beach managers better inform the public about water quality issues, Congress passed the Beaches Environmental Assessment and Coastal Health (BEACH) Act in October 2000. The Act authorizes EPA to provide grants to coastal and Great Lakes states, territories and tribes to develop and implement beach water quality monitoring programs and inform the public about the risk of exposure to disease-causing microorganisms in the water. EPA has awarded over $100 million in grants since 2001. Supplemental Grant A/location Formula Implemented In 2010, the BEACH Act’s tenth year, the Agency awarded almost $10 million to eligible state, territorial and tribal governments. EPA set aside $100,000 for eligible tribes to develop beach programs. EPA also implemented a supplemental formula, which is used for two purposes: • Allocate appropriated grant funds in excess of $10 million. • Reallocate BEACH Act grants funds older than three years left unspent by states and territories. The supplemental formula considers beach miles and beach use. The results of the base and supplemental formulas are added together to arrive at a total grant for each eligible state and territory. 2011 Grants Solicitation EPA released its 2011 BEACH Act grants solicitation notice in December 2010. This slightly earlier release allows the Agency to award the annual grants earlier so that eligible states, territories and tribes can use the funds to prepare for the peak beach season in summer 2011.

National 2009 Summary of State Beach Closings and Advisories Each spring, OST releases a report summarizing notification actions—the number, location and duration of beach closings and advisories—in the United States during the previous year’s swimming season. In May 2010, OST released a national summary report of state data on beach closings and advisories during the 2009 beach season. The report, which showed that monitored beaches were open and not under advisories 95 percent of beach season days, is supplemented by state reports that include program- specific accomplishments, issues and other information provided by the states and made available on EPA’s Beach Monitoring and Notification website at http.;’/water epa.gov/type/oceb/beaches/seasonsj009jndex. ci. ‘ 4 F BEACH CLOSED W . . r ( ------- \ ‘-. 0 ‘ c2 1) JI OST develops risk assessments and provides other human-health effects information for drinking water contaminants in support of Safe Drinking Water Act (SDWA) regulatory decisions. This work includes scientific and technical analyses that support development of contaminant candidate lists, regulatory determinations and six-year reviews of currently regulated drinking water contaminants. Endocrine Disruptor Screening Process and SDWA OST worked with the Office of Ground Water and Drinking Water (OGWDW) and the Office of Chemical Safety and Pollution Prevention to develop the second list of chemicals to be screened under the Endocrine Disruptor Screening Program. The list contains 134 chemicals that have been identified as priorities under the Safe Drinking Water Act because they may be found in sources of drinking water that may expose a substantial number of people. Published in November, this list also includes pesticide active ingredients that are being evaluated under EPA’s registration review program to ensure they meet current scientific and regulatory standards. The data generated from this review will provide robust and systematic scientific information to help EPA identify if additional testing is necessary or if other steps are required to address potential endocrine-disrupting chemicals. After public comment and review, EPA will issue test orders to pesticide registrants and the manufacturers of these chemicals to compel them to generate data to determine whether their chemicals may disrupt the endocrine system’s estrogen, androgen and thyroid pathways. EPA will begin issuing orders for this second group of 134 chemicals beginning in 2011. Fluoride Risk Assessment EPA established regulations for fluoride in drinking water in 1986, including a non- enforceable Maximum Contaminant Level Goal (MCLG) and a Secondary Maximum Contaminant Level (SMCL). The scientific basis for the health assessments that underlie the MCLG and SMCL was evaluated by the National Research Council (NRC) at the request of the EPA in 1993 and 2006 due to new studies on the health effects of ingested fluoride in humans and laboratory animals. The most recent NRC panel recommended that EPA conduct a new quantitative risk assessment for the tooth enamel pitting of severe dental fluorosis, low level fluorotic bone damage and the risk for increased bone fractures. As recommended by NRC, EPA conducted a quantitative dose-response assessment based on the available data for severe dental fluorosis. EPA also wrote a document on environmental exposure of children and adults to fluoride and the relative source contribution for water. Both documents will be released in early 2011.

DRINKING WATER SUPPORT 4 ‘F (, — I I 0 J . r. : ‘ : -- ------- r C, DEVELOPMENT OF NEW RECREATIONAL WATER QUAHTY CRITERIA The BEACH Act requires EPA to publish new recreational water quality criteria that states can use to strengthen their WQS programs and protect millions of swimmers in the United States from illnesses associated with water contaminated with pathogens. Stakeholder Engagement In October 2010, OST conducted its annual Recreational Water Quality Criteria Stakeholder Meeting via the Web. The stakeholder meeting was held to solicit input and to give stakeholders the opportunity to bring issues to EPA on the development of new recreational water quality criteria. The webinar also provided stakeholders with an update on EPA’s research for the development of recreational water quality criteria and EPA’s current thinking on criteria elements. For more information about the stakeholder meeting, please visit Completion of Underlying Research To develop new criteria that reflect current scientific data, OST and the Office of Research and Development (ORD) are implementing the Critical Path Science Plan (Science Plan) developed by U.S. and international scientific experts and published by EPA in 2007. In accordance with the Science Plan, EPA completed more than 30 studies in 2010 that, in conjunction with other research, will serve as the scientific basis for the revised criteria. The studies include epidemiology studies, site characterization studies, a Quantitative Microbial Risk Assessment, indicator/ methods development and validation studies and modeling. OST also is working closely with the Water Environment Research Foundation and other stakeholders as they perform research related to quantitative microbial risk assessment, pathogens and indicators in inland waters, and pathogens and indicators in tropical and subtropical waters.

DEvELOPMENT OF NUMERIC NUTRIENT CRITERIA OST’s Numeric Nutrient Criteria Program supports states, territories and authorized tribes in developing numeric criteria for nutrient- related variables including nitrogen, phosphorus, water clarity and chlorophyll-a. Guidance on Stressor-Response Approach to Criteria Development In 2010, EPA completed guidance for using stressor-response relationship approaches to derive numeric nutrient criteria. The draft document was peer reviewed by EPA’s SAB, which supports developing guidance on the use of this approach. The SAB review brought several key issues to light, including how to describe the appropriate use of these statistical methods and approaches in a national context. The final version of the guidance addresses the SAB’s recommendations, yielding a clear, useful document that will help states in developing numeric nutrient criteria with a sound scientific basis.

EPA has asked the SAB to conduct the external peer review of the methods document, uMethods and Approaches for Deriving Numeric Criteria for Nitrogen/Phosphorus Pollution in Florida’s Estuaries, Coastal Waters, and Southern Inland Flowing Waters.” The SAB will provide advice and recommendations to EPA on the technical accuracy of the approaches and analyses being considered for derivation of numeric nutrient criteria in Florida estuaries, coastal waters and southern inland flowing waters. The SAB held public meetings to initiate the review on December 13 and 14, 2010. A final review from the SAB is expected in the spring of 2011. CWA-FLFRA COMMON EFFECTS ASSESSMENT METHODOWGY FOR PESTICIDES Both OW and the Office of Pesticide Programs are responsible for evaluating aquatic ecotoxicity data to assess ecological effects of chemicals in surface water. In characterizing pesticide effects, both programs consider acute effects as well as chronic and sub-lethal effects on growth, survival and reproduction in their assessments. Stakeholders have identified a need for consistent and timely federal input that will allow EPA, states, tribes and the public to determine if pesticides represent a concern for aquatic life. EPA is now exploring how to build on the substantial high-quality science developed under both programs to develop additional tools and approaches to support a consistent, common set of effects characterization methods using the best available information. EPA held several public meetings in 2010 to solicit stakeholder input on its initial considerations regarding a common effects assessment process and the scope and content of three white papers about using tools to estimate aquatic toxicity data; approaches for deriving community-level benchmarks; and procedures for better integrating plant effects data into community-level assessments. A formal peer review process of these methodologies will be held in the fall of 2011.

FISH CONTAMINATION PROGRAM Great Lakes Human Health Fish Tissue Study Under the Agency’s National Coastal Condition Assessment, OST collaborated with the Great Lakes National Program Office and Office of Research and Development to begin the first statistically- based study of fish contamination in the Great Lakes. OST collected samples at about 150 near-shore sites in the Great Lakes for analyses relating fish contaminant data to human health. EPA expects to report the study results in 2012 and 2013. I I ( --12 ‘. ‘— ------- Mississippi Delta Environmental Justice Fish Advisory Effectiveness Study Under a grant from OST, the Mississippi Department of Environmental Quality (MDEQ) issued in 2000 a still-standing regional Delta advisory from Memphis to Vicksburg because of high levels of the pesticide DDT in fish harvested from Delta waters. MDEQ initiated an extensive outreach campaign in 2001 to make people aware of the advisory. In December 2010, OST completed a report evaluating the effectiveness of the Regional Mississippi Delta fish advisory. In cooperation with MDEQ and the U.S. Food and Drug Administration, OST conducted a survey in 2008-09 to understand the extent to which the Delta population who catches or eats wild fish from the Delta is aware of the advisory. The study also sought to understand the changes made in the types of fish caught and eaten by those who are aware the advisory. The study concluded that although only 28 percent of those surveyed were aware of the advisory, 91 percent of those who were aware followed the meal advice. OST will present the details of the study at the 2011 National Fish Forum and intends to develop national guidance on conducting surveys of rural populations in 2012. MDEQ will use the survey results to improve future outreach campaigns in the Delta. GuL.F Oft SPftL RESPONSE OST experts played a key role in OW’s response to the Gulf Oil Spill. OST led the development of groundbreaking science to assess the potential impacts of oil-related compounds on human health and the environment. OST quickly reviewed the available science and literature to derive water column and sediment benchmarks for an array of oil constituents. The benchmarks included a range of environmental and human exposure considerations and assumptions. OST staff also worked effectively with other federal agencies to derive and review the chronic and acute benchmarks. Along with the National Oceanic and Atmospheric Administration and the Food and Drug Administration, OST also played an integral role in the development of the seafood safety reopening protocol to document the process for when and how fish and shellfish areas would be assessed to make decisions to reopen to commercial fishing to ensure consumer safety. The federal and state workgroup on seafood safety, on which OST participates, will soon begin developing a long-range monitoring plan designed to ensure the continued safety of seafood from the Gulf of Mexico. In addition, many OST staff and managers played critical leadership roles in EPA’s Emergency Operations Center (EOC), performing many crucial functions: • Supporting the assessment of water and sediment samples against the chronic and acute benchmarks. ________________________ • Coordinating the review of proposals for booms, berms and barriers. • Developing staffing plans and operating procedures to ensure that the EOC was properly staffed seven days a week and twelve hours a day. • Fielding and responding to a variety of technical, policy and communication requests. • Representing OW in daily senior leadership meetings with EPA’s Administrator. ,t I * .. ,h\ ‘ ( .

Key actions include the following: • 2010 Effluent Guidelines Program Plan—EPA will publish a final 2010 Effluent Guidelines Program Plan summarizing the status of ongoing rulemakings and industries for which effluent guideline regulations will need to be revised or established. This will include proposing a new regulation to limit mercury waste from dental offices. • Stormwater Rule Addressing Post-Construction Discharges—EPA will issue a proposed rule in 2011 to establish a program reducing stormwater discharges from new development and redevelopment. • Rulemaking to Reduce Pollutant Discharges at Airports—EPA will issue a final rule to control pollutant discharges associated with deicing airplanes and runways. • Estuarine, Coastal and Southern Inland Flowing Waters Rulemaking for Florida—EPA will propose numeric nutrient criteria for Florida’s estuarine, coastal and southern inland flowing waters in November 2011. The rulemaking will also include the procedure to adjust stream criteria to protect downstream estuaries. • Proposed WQS Regulatory Revisions—EPA expects to propose revisions to the current Water Quality Standards regulation in summer 2011. • CWA-FIFRA Common Effects Assessment Methodology for Pesticides— EPA will conduct a formal peer review of these methodologies in the fall of 2011. • Rulemaking to Minimize Impacts from Cooling Water Intakes—EPA will propose standards to protect fish and other aquatic organisms from being killed or injured by cooling water intake structures at power plants and other industrial facilities. • National Coastal Assessment—Fish fillet composite samples collected in 2010 for the National Coastal Assessment will be analyzed in 2011 for mercury, perfluorinated compounds, omega-3 fatty acids, pharmaceutical compounds and polybrominated diphenyl ethers. • Beach Program—OST will host the 2011 Beach Conference from March 15 to March 1] in Miami, FL. The conference will include workshops on predictive modeling tools and rapid analytical methods. OST looks forward to collaborating with stakeholders and other partners to achieve effective outcomes for these and other projects on the horizon in 2011. : ‘ j ) ) ) -‘ F.’ ‘ ------- |
