ABCWUA Southside Water Reclamation Plant, 4201 Second Street SW, Albuquerque, New Mexico

Albuquerque Bernalillo County Water Utility Authority (ABCWUA) requests a modification to their air quality permit in Application #0786-M6

The applicant is requesting a modification to Permit #0786-M3-RV1 for their wastewater treatment and reuse water production facility.  The applicant proposes to modify the following:

  • Update the unit numbers of all emission units associated with the SWRP;
  • Update the emissions of all the equipment associated with the water treatment process using TOXCHEM to estimate emissions from Volatile Organic Compounds (VOCs), Hazardous Air Pollutants (HAPs) and Hydrogen Sulfide (H2S);
  • Update emissions associated with the cogeneration engines, which will be equipped with Selective Catalytic Reduction (SCR) and oxidation catalyst to control and reduce the emissions of Nitrogen Oxides (NOx), Carbon Monoxide (CO), VOCs, and HAPs;
  • Include the construction and operation of the new North Preliminary Treatment Facility and the associated emissions that are routed to a combination of two Bohn biofilters and an activated carbon unit that control H2S emissions;
  • Include emissions from the new coarse screening facility;
  • Update the use and emissions from Clarifiers #1 through #8;
  • Update NOx, CO and VOC emission factors for the flares by using factors representative of wastewater treatment digester gas and site-specific data;
  • Update VOC emissions for the unleaded gasoline fuel storage tank;
  • Modify the Sulfur Oxides (SOx) emissions from the Ultra-Violet Facility Emergency Generator to account for the use of ultra-low sulfur diesel fuel;
  • Update the information and number of emergency generators;
  • Revise the H2S control efficiencies for all activated carbon filters and biofilters to 98%;
  • Update Miscellaneous External Combustion Sources and emissions based on process specific fuel-burning equipment;
  • Update the slight increase of the facility-wide emissions of H2S, as a result of TOXCHEM modeling; and
  • Update and decrease the facility-wide emissions for NOx, CO, VOCs, SO2, Particulate Matter <10 microns (PM-10) and Particulate Matter <2.5 microns (PM-2.5), formaldehyde and total HAPs as a result of the proposed controls for the cogeneration engines and associated controlled emission calculations.
