Pittsboro Water Quality Task Force Final Report Pittsboro Water Quality Task Force –FINAL REPORT– October 2020 BACKGROUND In November 2019, the Town of Pittsboro’s Board of Commissioners approved the creation of an advisory Task Force named the Pittsboro Water Quality Task Force (PWQTF). As detailed in [Appendix A], the PWQTF was charged with the following mission: To assist the Board of Commissioners in its assessment of unregulated contaminates in Haw River and the appropriate response thereto. The Board directed the PWQTF to address the following concerns regarding the Town’s water supply: 1. Help focus attention on specific issues and problems anticipated as a result of the presence of the unregulated contaminates, including per- and polyfluoroalkyl substances (PFAS) and 1,4-dioxane in the Town’s drinking water source. 2. Evaluate alternative supply sources of drinking water for the Town while considering the future needs of the Town, including review of the existing studies by the Jordan Lake Partnership for a Western Intake and the Chatham County Master Utilities Plan. 3. Consider recommendations for the protection of vulnerable populations, such as public schools and entities caring for the elderly and infirmed within the Town. The varied backgrounds of each Task Force member offered an extensive level of experience in science, education, environmental advocacy, and policy development toward accomplishment of the Task Force mission. PWQTF members met twelve times between February and October 2020. During that period, the Task Force enlisted a wide range of experts to solicit data on water quality findings, and background on water resources management decisions. Presentations, data, and discussions offered by these professionals included material related to the characteristics of emerging contaminants, results of pollutant tracing and monitoring, information on how the pollutants affect human health, discussions on parallel programs and water quality enhancement efforts regionally, and Chatham Park’s water reclamation facility and reuse projections. Science and industry professionals who contributed to the Task Force findings included: Dr. Linda Birnbaum, Toxicologist, NIEHS (retired) Dr. Detlef Knappe, Environmental Engineer for NC State Dr. Heather Stapleton, Environmental Chemist for Duke University Mr. Mick Noland, Chief Water Officer for Fayetteville Public Works Chris Blice, Chatham County School Operations Officer Mr. Tim Baldwin and Mr. Josh Powell, treatment engineers from the Chatham Park Decentralized Water Resource Recovery Facility (WRRF) 16-Oct-20 1 Pittsboro Water Quality Task Force SUMMARY This Report will reference the term “emerging contaminants” in reference to 1,4-dioxane [Appendix B] and per- and polyfluoroalkyl substances (PFAS) [Appendix C]. The Task Force extensively assessed immediate, short-term, and long-term options available to the Town of Pittsboro. PWQTF recommends the following three areas of action to the Pittsboro Board of Commissioners: I. Develop an Emerging Contaminants Mitigation and Response Plan in coordination with upstream and downstream municipalities. II. Assess the Town’s long-term water resources management options using a strategic decision matrix and cost-benefit analysis. III. Educate Town water users about Emerging Contaminants through a public awareness program, and provide short-term options to reduce exposure. AREAS OF ACTION The following areas of action lay out the immediate, short-term, and long-term actions needed to address the detrimental health risks presented by emerging contaminants in the Town’s drinking water supply. I. Develop an Emerging Contaminants Mitigation and Response Plan in coordination with upstream and downstream municipalities. The most effective means to address emerging contamination in the Town’s water supply is to stop the contamination at the source. There are multiple known sources of contamination stemming from within the municipalities of Reidsville, Burlington, and Greensboro. The PWQTF recommends that the Town Mayor, Manager, and Public Utilities Director immediately contact their upstream peers in Reidsville, Burlington, and Greensboro about the Town’s concerns with their wastewater discharges. This alert should serve to establish regular communication and meetings with each of the town’s mayors, town managers, and wastewater treatment facility managers. This will establish a baseline of communication in order to halt contaminating discharges into the Haw River from three municipalities known to be causing contamination. To stop contamination at the source, these three municipalities must get involved with local industrial discharge customers. We have attached [Appendix D] for all necessary contact information. The PWQTF also recommends immediate coalition-building with downstream Cape Fear River governments, whose citizens are also impacted by the contamination within the Haw River water. In the near future, we could be sending reverse osmosis waste downstream, via the surface water, and our downstream users have a right to know. Regular communication and meetings should be established between the Pittsboro Town government and the Cape Fear governments. 16-Oct-20 2 Pittsboro Water Quality Task Force Forming a strong coalition will also serve to build a much larger voice for state government to hear the demands of the people—toward the end goal of establishing regulatory guidelines for PFAS and 1,4-dioxane, which do not currently exist. As a result of pressure from state water advocacy groups and town governments, Attorney General Josh Stein has recently launched an investigation into PFAS discharges throughout the state. Thus far, the Task Force has engaged in commenting and reviewing changes to permits through the Special Order by Consent for Greensboro. [Appendix E] provides a list of coalition-building contact information. The PWQTF recommends a local representative be designated to participate and provide a voice on the 1,4-dioxane stakeholder conference call that is hosted on a quarterly basis by Kim Nimmer, Emerging Compounds Coordinator for Division of Water Resources. These calls allow stakeholders from municipalities, state agencies, academic researchers, and community groups to discuss ongoing research, issues, and potential solutions to 1,4-dioxane contamination issues across the Cape Fear Basin. In addition, Pittsboro town government should become involved with the already-organized Upper, Middle and Lower Cape Fear River Basin Associations to form the backbone of their coalition [Appendix F]. The PWQTF—if extended—would help assist with all applicable communication by drafting letters and setting regular meetings between the Town and upstream and downstream governments. The PWQTF notes that, after the departure of the Town Engineer in early 2020, the Town has not had staff to manage such efforts. II. Assess the Town’s long-term water resources management options using a strategic decision matrix and cost-benefit analysis. It was beyond the scope and expertise of the PWQTF to develop an engineering report or a cost-benefit analysis to evaluate the town’s options for water infrastructure. However, the group reviewed existing reports and offers summary and recommendations. Documents and reports reviewed by PWQTF are summarized as follows: Jordan Lake Western Intake [Appendix G and Appendix H] Pittsboro is a member of the Triangle Water Partnership (TWP), formerly known as Jordan Lake Partnerships. Pittsboro is one of four partner members—along with Durham, Chatham County, and OWASA—that plan to draw water from the western side of Jordan Lake. All forecasts share a common element: they start with a regional raw water intake and pumping station that is built on a site owned by OWASA, near Vista Point. No prior analysis has been conducted for alternative sites nor for Pittsboro having independent access to an intake. In the analysis, the raw water intake is sized for the needs of all four partners, with cost based on their percentage of water needed. This path was chosen based on early discussions with NC Division of Water Resources (DWR) and the US Army Corps of Engineers (USACE). These bodies are likely to approve only one more publicly owned water supply intake on the Lake— which would require regional cooperation. The total anticipated costs for the raw water intake, pump station, and regional Water Treatment Plant for Phase 1—with a maximum day capacity of 33 mgd (million gallons per 16-Oct-20 3 Pittsboro Water Quality Task Force Report day)—was $243.3 million in 2014. Pittsboro’s contribution was $29.5 million, for a withdrawal average of 2 mgd. No cost analysis has been done for Pittsboro to pursue an independent intake or to initiate the process independently, but it would not likely be approved. Increasing financial investment into this partnership would not expedite the process at this point as the lead agency for the Western Intake has always been Durham, which funded the initial engineering design costs. The current goal is to have a regional intake operating by 2031. PWQTF recommends that Pittsboro remain engaged in pursuing the Western Jordan Intake and explore strategies to expedite the process. The Western Intake offers the benefits of regional collaboration, advanced drinking water treatment, and a more protected water supply. However, this is a long-term solution. While it should be pursued, it will not adequately and urgently address the immediate emerging contamination problem. 2020 Chatham County Water and Wastewater Utility Master Plan [Appendix

History, Occurrence, and Uses Mosander extracted from the mineral lanthana a rare earth fraction, named didymia in 1841. In 1879, Boisbaudran separated a rare earth oxide called samaria (samarium oxide) from the didymia fraction obtained from the mineral samarskite. Soon after that in 1885, Baron Auer von Welsbach iso- lated two other rare earths from didymia. He named them as praseodymia (green twin) and neodymia (new twin) after their source didymia (twin). The name praseodymium finally was assigned to this new element, derived from the two Greek words, prasios meaning green and didymos meaning twin. Praseodymium occurs in nature associated with other rare earths in a rel- atively high abundance. It is more abundant than some common metals such as silver, gold, or antimony. The average concentration of this metal in the earth’s crust is estimated to be 8.2 mg/kg.

MEYER. (From the Laboratories of Physiology and Physiological Chemistry of Colum- bia University, at the College of Physicians and Surgeons, New York.) PLATE XVI. The present study was undertaken with a view of determining in a general way the effects of intravenous administration of ra- dium upon the circulation and respiration. The problem was sug- gested to us by Dr. William J. Gies, under whose guidance a number of researches, dealing with the more extensive question of the action of radium upon animal and vegetable cells, have re- cently been carried on in the laboratories of Columbia University.1 For the radium used in these experiments we are greatly in- debted to Mr. Hugo Lieber. It was supplied to us in the form of the bromide, in preparations of 240 , iooo, and io,ooo activities. The strength of the solution used was the same in all cases. It contained 45 rag. of the dry substance in 25 c. c. of the solvent; each cubic centimeter of the solution, therefore, contained 1.8 rag. of the radium preparation. The amount of the radium present varies directly with the ra- dio-activity. Preparations of ~,5oo,ooo activity are said to repre- sent pure radium bromide3 Taking this figure as the standard of purity, ~ .8 rag. of the radium preparation of io,ooo activity contained approximately only o.o~ 26 mg., the same quantity of the preparation of ~ooo activity contained o.ooi26 rag.

Schumer Republican Leader Democratic Leader United States House of Representatives United States Senate Washington, DC 20510 Washington, DC 20510 Dear Speaker Pelosi, Leader McCarthy, Leader McConnell and Leader Schumer: RE: Urgent Action Needed on President-Elect Biden’s American Rescue Plan On behalf of The United States Conference of Mayors, we urge you to take immediate action on comprehensive coronavirus relief legislation, including providing direct fiscal assistance to all cities, which is long overdue. President-elect Biden’s American Rescue Plan contains such assistance as part of an aggressive strategy to contain the virus, increase access to life-saving vaccines, and create a foundation for sustainable and inclusive recovery. American cities and our essential workers have been serving at the frontlines of the ongoing COVID-19 pandemic for nearly a year. We have been charged with executing herculean public health efforts and an unprecedented emergency response. Despite immense fiscal pressure, your local government partners oversaw those efforts, while trying to maintain essential services and increase our internal capacity to provide support for residents and businesses who have been crippled by a tanking economy. And yet, as the economic engines of our country, local governments will be relied upon to lead the long- term economic recovery our nation so desperately needs, even as, with few exceptions, cities have been largely left without direct federal assistance.

  • Products Evolved During Hot Gas Welding of Fluoropolymers
    Health and Safety Executive Products evolved during hot gas welding of fluoropolymers Prepared by the Health and Safety Laboratory for the Health and Safety Executive 2007 RR539 Research Report Health and Safety Executive Products evolved during hot gas welding of fluoropolymers Chris Keen BSc CertOH Mike Troughton BSc PhD CPhys MInstP Derrick Wake BSc, Ian Pengelly BSc, Emma Scobbie BSc Health and Safety Laboratory Broad Lane Sheffield S3 7HQ This report details the findings of a research project which was performed as a collaboration between the Health and Safety Executive (HSE) and The Welding Institute (TWI). The project aim was to identify and measure the amounts of products evolved during the hot gas welding of common fluoropolymers, to attempt to identify the causative agents of polymer fume fever. Carbonyl fluoride and/or hydrogen fluoride were detected from certain fluoropolymers when these materials were heated to their maximum welding temperatures. Significant amounts of ultrafine particles were detected from all of the fluoropolymers investigated when they were hot gas welded. The report concludes that fluoropolymers should be hot gas welded at the lowest possible temperature to reduce the potential for causing polymer fume fever in operators. If temperature control is not sufficient to prevent episodes of polymer fume fever, a good standard of local exhaust ventilation (LEV) should also be employed. This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the authors alone and do not necessarily reflect HSE policy.

HER David Purser Role of fire retardant treatments Benefits of fire retardant treatments: 1. Reduce probability that a heat or ignition source will initiate a growing spreading fire – Reduce initial ignition probability – If ignition does occur may result in self- extinction/failure of propagation – Thereby essentially eliminate the toxic and environmental hazards from fires prevented 2. If the initial ignition resistance is overcome may reduce the rate of fire growth – May result in a period of very slow growth up to a critical fire size – Or may provide a slower t2 fire growth curve – In such cases may reduce the rate of toxic hazard development and increase the time available for escape or fire fighting HER David Purser BS7974 fire growth rate curves t^2 fire growth curves 10000 9000 8000 7000 6000 5000 4000 Slow 3000 Medium Heat release rate (Kilowatts) 2000 Fast Ultrafast 1000 Explosion 0 0 100 200 300 400 500 600 Time (s) HER David Purser BS7974 fire growth rate curves CBUF chairs HER David Purser Limitations of fire retardant treatments • Do not provide non-combustibility, but ignition resistance to a heat source up to a design limit.

OCCUPATIONAL EXPOSURE TO DECOMPOSITION PRODUCTS of FLUOROCARBON POLYMERS U.S. DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Public Health Service Center for Disease Control National Institute for Occupational Safety and Health September 1977 For sale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 DHEW (NIOSH) Publication No. 77-193 PREFACE The Occupational Safety and Health Act of 1970 emphasizes the need for standards to protect the health and safety of workers exposed to an ever-increasing number of potential hazards at their workplace. The National Institute for Occupational Safety and Health has projected a formal system of research, with priorities determined on the basis of specified indices, to provide relevant data from which valid criteria for effective standards can be derived. Recommended standards for occupational exposure, which are the result of this work, are based on the health effects of exposure. The Secretary of Labor will weigh these recommendations along with other considerations such as feasibility and means of implementation in developing regulatory standards. It is intended to present successive reports as research and epidemiologic studies are completed and as sampling and analytical methods are developed. Criteria and standards will be reviewed periodically to ensure continuing protection of the worker. I am pleased to acknowledge the contributions to this report on the decomposition products of fluorocarbon polymers by members of the NIOSH staff and the valuable constructive comments by the Review Consultants on the Decomposition Products of Fluorocarbon Polymers and by Robert B.
