Integrated Solutions for Coal Combustion Residuals and the Effluent Limitation Guidelines Compliance

Coal Combustion Residuals (CCRs) — fly ash, bottom ash, boiler slag, and flue gas desulfurization (FGD) materials—continue to be a major waste stream from coal-fired power plants. Following EPA’s publication of the final CCR Rule on April 17, 2015 (with an effective date of October 19, 2015), all U.S. coal-fired power plants must develop compliance strategies for CCR landfills and CCR surface impoundment. Key compliance considerations for existing and inactive facilities include:

  • Location criteria (water table, wetlands, faults, seismic impact Zones)
  • Design (structural stability, composite liners, emergency action plan)
  • Operations (fugitive dust and run-on/run-off control plans)
  • Groundwater, sampling, monitoring and protection
  • Facility closures with CCR in place and with CCR removal

Effluent Limitation Guidelines (ELG): The final ELG rule was promulgated and became effective on January 4, 2016, under the Clean Water Act and establishes new requirements for steam power plant wastewater streams. Highlights include:

  • New discharge requirements for flue gas desulfurization (FGD) wastewater
  • Zero discharge requirement for ash transport and bottom ash waters
  • A compliance date of “as soon as possible” after November 1, 2018
  • Additional years of compliance for evaporative technologies until 2023
  • Anti-circumvention provisions  

 

Complying with CCR and ELG Regulations

Amec Foster Wheeler’s Team will conduct a free webinar which will review the CCR and ELG rules and strategies that coal-fired power plants must consider to achieve compliance.

CCR dry conversion systems and equipment will be discussed, including:

  • Typical equipment and systems used in wet to dry ash conversions for bottom ash and fly ash handling
  • Consideration for bottom ash closed-loop systems
  • Considerations for fly ash dry handling systems
  • Discussion of ash storage and disposal alternatives

Surface impoundment closure options will be reviewed highlighting:

  • A surface impoundment closure framework
  • Surface impoundment closure approaches and considerations for closure by removal, in place closure, and hybrid closure
  • Comparison and selection of the preferred closure approaches

ELG treatment technologies and issues that will be presented include:

  • Physical chemical treatment
  • Biological treatment processes for meeting selenium and nitrogen limits
  • Polishing technologies, such as zero valent iron
  • Evaporation technologies including spray dryers and mechanical evaporators
  • Paste processes

Questions from attendees will be addressed during the Q&A session of the webinar.

This webinar can help power producers make informed decisions about CCR and ELG Rule compliance strategies. Register today to secure your spot in this free webinar!
