DISPOSAL/RECOVERY OPTIONS FOR BRINE WATERS FROM OIL AND GAS PRODUCTION IN NEW YORK STATE nmxou NERGY AND DEVELOPMENT AUTHORTIY The New York State Energy Research and Development Authority (NYSERDA) is a public benefit corporation created in 1975 by the New York State Legislature. F. William Valentino is President and Chief Operating Officer. NYSERDA's primary mission is to carry out a broad program of energy research, development and demonstration projects designed to develop and apply efficient technologies to help ensure that New York has secure and economical future supplies of energy, while protecting environmental values and promoting economic growth. NYSERDA derives its basic research revenues from an assessment levied on the intrastate sales of New York State's investor-owned electric and gas utilities. Additional research dollars come from limited corporate funds and a voluntary annual contribution by the New York Power Authority. In its research program, NYSERDA stresses consultation and collaboration with other organizations, including utilities, universities, industries, private engineering and scientific research firms, local governments, and Stateand federal agencies. These efforts stretch NYSERDA's limited research funds and ensure the involvement of those who can use the results of the research. In its federally funded Energy Services program, NYSERDA provides technical assistance to improve the energy and environmental performance of businesses and institutions, helps secure energy-project funding from private and public sources, and converts fleet vehicles to alternative fuels. The Energy Analysis program focuses on using energy, regulatory, and environmental policies to help New York State businesses grow and to meet the needs of New York State's energy consumers. NYSERDA also has responsibility for: • Managing the 3,300-acre Western New York Nuclear Service Center at West Valley 35 miles south of Buffalo, the site of a former commercial nuclear fuel reprocessing plant and a low-level radioactive waste disposal area. These responsibilities include: — Participating in the West Valley Demonstration Project, a joint federal/State effort to solidify the high-level radioactive wastes left over from the reprocessing operation and to clean up the facilities used. — Maintaining the portion of the site not being used in the Demonstration Project, including the shut-down low-level radioactive waste disposal area • Issuing tax-exempt bonds to finance facilities for electric and gas utilities and energy projects for private companies. • Constructing and operating facilities for disposal of low-level radioactive wastes produced in New York State, once the State makes disposal method and site decisions and approvals have been issued by State regulatory agencies. • Managing a 365-acre portion of a Superfund clean-up site in Malta, 20 miles north of Albany. Part of the site was once owned by the federal government Portions of it have been used by the federal government and its contractors since the 1940s for activities that have included rocket engine and fuel testing, weapons testing, and space research.

Final Report ii Brine Disposal Study ABSTRACT Produced water from oil and gas operations, or brine as it is typically referred, may be characterized as being highly saline, with total dissolved solids greater than 100 g/L. If these brines are disposed improperly there may be severe adverse environmental effects. Thus, it is important that brine be disposed using environmentally sound methods. Unfortunately, costs for the disposal of brine water are a significant burden to oil and gas producers in New York State. These costs and the relatively low market price of oil and natural gas have contributed to the decline in gas and oil production in New York State during the past 10 years. The objectives of this study were to evaluate new and existing options for brine disposal in New York State, examine the technical and economic merits of these options, and assess environmental impacts associated with each option. Two new disposal options investigated for New York State oil and gas producers included construction of a regional brine treatment facility to treat brine prior to discharge into a receiving water and a salt production facility that utilizes produced water as a feed stock. Both options are technically feasible; however, their economic viability depends on facility size and volume of brine treated.
