  • Energy Industry Slams EPA Fracking Wastewater Plan
    Providers News Feature August 19 2015 Energy Industry Slams EPA Fracking Wastewater Plan By Sara Jerome sarmje The EPA s plan to ban the processing of fracking waste at municipal treatment plants is drawing heated criticism from the energy industry Fuel companies are calling it a short sighted measure that ignores its long term needs and violates the Clean Water Act according to NPR The Independent Petroleum Association of America argued that the EPA had overstepped its bounds by proposing an outright ban on the practice rather than requiring that municipal treatment plants use technology to remove contaminants from fracking wastewater The practice is not currently used but it was used in the past Some plants continue to receive such requests from gas companies so the rule is designed to prevent any resumption of that practice the EPA said when publishing the rule in March the report said The environmental community applauded the EPA effort Rachel Richardson director of Environment America s Stop Drilling program weighed in favorably It s crazy that highly toxic radioactive wastewater can still be treated at the same place as dirty bath water then released into the rivers and lakes we drink from she said Preventing this practice is a critical step toward protecting our water and our health from the dangers of fracking The Houston Chronicle provided background on the rule At issue is the Environmental Protection Agency s proposal to block companies from sending that drilling wastewater to municipal treatment facilities ill equipped to remove the naturally occurring radium bromide and other toxins carried with the fluid out of the ground When salty bromide mixes with chlorine at treatment plants it can produce trihalomethanes linked to bladder cancer and miscarriages Pennsylvania officials concerned about that toxic combination and facing pressure from the EPA

  • The User’s Guide To Integrated Planning
    primary trade and lobbying group is developing a set of tools and data to help communities pursue wastewater and stormwater projects that integrate multiple disciplines while complying with regulations and keeping costs down The project is called the User s Guide for Integrated Planning for Wastewater and Stormwater It is expected to cover facility planning and asset management economics watershed and infrastructure modeling green infrastructure water quality compliance and planning and legal needs WERF also hopes to identify and include the top 10 reasons communities are or are not pursuing integrated planning for their peers consideration The guide is being produced by a consortium of parties Scientific specialists Geosyntec Consultants and environmental law firm Barnes Thornburg are working to identify the growing need for integrated planning in wastewater and stormwater Patricia McGovern Engineers has been tapped for its analytical expertise in the water industries and the University of Cincinnati Economics Center is tasked with providing financial analyses to help planning decisions The project team will compile information from case studies to develop a list of integrated planning tools and data needed and identify gaps with each said Carrie W Capuco WERF Director of Communications For each tool we will have information about why communities selected the tools they are using and the strengths weaknesses and drawbacks associated with their use The project team members with expertise in different areas of integrated planning will provide qualitative and readily available information about the level of complexity cost and other factors for applying tools as well as the data collected to inform them The guide emerged as an answer for a changing dynamic between wastewater and stormwater regulations and the practicality of developing new projects For 43 years individual regulators have been trained in the pollutant by pollutant permitting and enforcement approach said Capuco referring to the time since the U S EPA introduced the Clean Water Act At a recent National Association of Clean Water Agencies workshop Capuco explained EPA regulators indicated that while the agency still plans to enforce its rules it is open to evaluating innovative solutions that consider the cost benefit financial impacts of complying with them Following that revelation the idea to develop a toolbox for integrated planning was born This research is intended to get communities talking with each other about integrated planning help align EPA s vision for integrated planning with the realities that municipalities face in implementing the Clean Water Act and Safe Drinking Water Act and to create a dynamic user s guide that provides municipalities and regulators with up to date information regarding the state of the science on integrated planning as it continues to evolve said Capuco Following an informal survey of clients WERF identified several consequences when municipalities push forward on separate wastewater and stormwater projects without coordinating them Communities face substantial challenges including difficulty engaging participants from disadvantaged communities a lack of coordination or integration of overlapping projects and programs and a lack of knowledge Capuco said As for communities

  • Compliance Tips For EPA’s New Power Plant Regulations
    to a surface impoundment i e ash settling pond Plants that generate fly ash transport water use surface impoundments to manage the wastewater EPA has not identified any facilities using more advanced treatment such as chemical precipitation or biological treatment to treat fly ash transport water EPA identified 393 generating units at 144 plants that wet sluice at least a portion of fly ash Wet sluicing systems use water powered hydraulic vacuums to withdraw fly ash from the hoppers The ash is pulled to a separator transfer tank combined with sluicing water and pumped to the surface impoundment to remove particulates from the wastewater by means of gravity before discharge to a receiving stream Many coal and oil fired power plants design their fly ash handling systems to minimize or eliminate the discharge of fly ash handling transport water Such approaches include Wet Vacuum Pneumatic System These systems use water powered hydraulic vacuums for the initial withdrawal of fly ash from the hoppers similar to wet sluicing systems Instead of sluicing the ash to a surface impoundment these systems capture the ash in a filter receiver bag filter with a receiving tank and then deposit the dry ash in a silo Dry Vacuum Pneumatic System These systems use a mechanical exhauster to move air below atmospheric pressure to pull the fly ash from the hoppers and convey it directly to a silo The fly ash empties from the hoppers in to the conveying system via a material handling valve Pressure System These systems use air produced by a positive displacement blower to convey ash directly from the hopper to a silo Each ash collection hopper is equipped with airlock valves that transfer the fly ash from low pressure to high pressure in the conveying line The airlock valves are installed at the bottom of the hoppers and require a significant amount of space Retrofit installations of pressure ash handling systems may require raising the bottom of the hopper Combined Vacuum Pressure System These systems use a dry vacuum system to pull ash from the hoppers to a transfer station where the ash is transferred from the vacuum low pressure to ambient pressure From the transfer station the fly ash is transferred via airlock valves to a high pressure conveying line A positive displacement blower conveys the ash to a silo Because the airlocks are not located under the hopper combination vacuum pressure systems have the space advantages of dry vacuum systems Mechanical System Oil fired units or other units that generate a low volume of fly ash may use manual or systematic approaches to remove fly ash e g scraping the sides of the boilers with sprayers or shovels then collecting and removing the fly ash to an intermediate storage destination or disposal Bottom Ash Transport Water Bottom ash at times also referred to as boiler slag is produced as fuel is burned in a boiler and collected in hoppers or other types of collection equipment directly below the boiler Generally boilers are sloped inward with an opening at the bottom to allow the bottom ash to feed by gravity into collection hoppers The hoppers contain water to quench the hot ash Once the hoppers are full gates at the bottom of the hoppers open releasing the bottom ash and quench water to a conveying line where the ash is diluted with water to approximately 20 percent solids by weight and pumped to a surface impoundment or a dewatering bin for solids removal Conveying bottom ash in a water slurry is called wet sluicing EPA identified 870 units 345 plants that wet sluice at least a portion of their bottom ash Many coal and oil fired power plants design their bottom ash handling systems to reduce or eliminate the discharge of bottom ash handling transport water Available technologies include Mechanical Drag System In these systems the ash collection hopper is replaced with a transition chute that routes the bottom ash to a water filled trough In the trough a drag chain continuously moves the ash to an incline where it is dewatered and then conveyed to a nearby ash collection area Excess quench water collected in the dewatering system is recycled to the quench water bath Although mechanical drag systems require little space under the boiler they may not be suitable for all boiler configurations Remote Mechanical Drag System These systems collect bottom ash in water filled hoppers and wet sluice the ash to a mechanical drag system located away from the boilers Sluice water collected from the dewatered bottom ash is collected and reused in the bottom ash handling system Plants can use remote mechanical drag systems to convert existing bottom ash handling systems with limited space or other configuration limitations One U S plant has installed and is currently operating a remote mechanical drag system to handle bottom ash At least one additional plant is currently installing a remote mechanical drag system to handle bottom ash Additionally a large U S power company has been evaluating installing remote mechanical drag systems for several of its plants Dry Vacuum or Pressure System These systems transport bottom ash from the boiler to a dry hopper without using any water The system percolates air through the ash to cool it and combust unburned carbon Cooled ash then drops to a crusher and is conveyed via vacuum or pressure to an intermediate storage destination Complete Recycle System Complete recycle systems transport bottom ash using the same processes as wet sluicing systems Plants can install complete recycle on existing wet sluicing units Instead of transporting it to an impoundment the ash is sluiced to dewatering bins where it is dewatered and moved to storage The transport sluice water is treated to remove solids in a settling tank and is recycled to the bottom ash collection system Prior to reusing the treated transport water plants may add treatment chemicals to the water to adjust pH and prevent equipment corrosion Vibratory Belt System Bottom ash

  • 7 Questions For Solving Odor Control
    status wasn t particularly easy to maintain It s necessary for all plants to fall in line with state and Department of Health regulations when addressing odor In the case of the NRWWTP located in New York the state has air quality standards that regulate hydrogen sulfide at levels of 10 ppb and the emission of volatile organic compounds VOCs These provided more tangible goals than a good neighbor guideline for the plant to follow if they hoped to get the permits necessary to install an odor control system Staying informed of the various health and environmental departments that regulate your jurisdiction is a first step towards controlling plant odor What are the odors and how strong are they The NRWWTP staged an odor investigation This was an evaluation of each plant process unit to determine the source and concentration of odors being emitted A wastewater fate model was used to assess the emission of toxic VOCs from each and this established the baseline odors and an initial view of areas that needed control The paper includes the following list of locations that were sampled at the NRWWTP Influent channel area in the influent pump station Primary settling tanks at the following locations influent mid tank effluent effluent launder and effluent channel Gravity thickener tanks exhaust Sludge storage tanks exhaust Sludge processing building exhaust Final settling tanks at the following locations center feed well mid tank and effluent launder Methods of analysis included hydrogen sulfide measurement testing of the dilution threshold and recognition threshold values at which someone can detect or recognize an odor reduced sulfur compound measurement and carbon dioxide measurement How do odors impact off site receptors An air dispersion model run with the baseline data collected during the odor investigation can determine the areas needing control the impact of the monitored odors and whether the plant has managed to comply with regulations In the case of the NRWWTP a locally approved model was used It s known as a Gaussian model a mathematical simulation of the buildings tanks enclosures and processes at the plant and all of the identified odor sources Odor receptors for the model were set up around the plant fence and in a rectangular grid at 100 and 500 meter intervals as they moved away from the fence line It was also set up to evaluate plant emissions using five years of meteorological data The model found that beyond the solids storage processing and truck load areas of the plant the headworks influent channels primary settling tanks and primary effluent channels had to be controlled What steps and technologies are necessary to mitigate the plant odors Finally after rigorous testing and analysis you will be ready to determine how to best rid your plant of odor Using the results of the odor investigation and air dispersion model conduct a technology review of what s available to cure your plant s foul smelling woes The NRWWTP ended up going with a packed tower wet scrubber
