Hobbs Generating Station

Turbine Upgrade

In the New Mexico Hobbs' facility, eSPARC designed a strategy to permit a turbine upgrade project, successfully avoiding Prevention of Significant Deterioration (PSD) permitting triggers. Go back to Representative Permitting & Strategy Projects.

Under 20.2.72.200.A(2) of the New Mexico Administrative Code (NMAC) and 20.2.74.200.A NMAC, eSPARC completed a significant permit revision that included:

  • Specific emission rate calculations for all operational scenarios and equipment being evaluated
  • Detailed Best-Available-Control-Technology (BACT) Analysis following EPA top-down methodology for all pollutants
  • Thorough State and Federal regulatory applicability analysis
  • Public notice support
  • Monitoring waiver request development
  • Air Dispersion waiver request submittal

The eSPARC modeling team completed the following air quality analysis:

  • NAAQS Significance Impact Level (SIL) and Radius of Impact (ROI) analysis for NO2  (1-hr), SO2 (1-hr) and PM2.5 (24-hr and annual)
  • Refined analysis for NO2 (1-hr) and PM2.5 (24-hr and annual)

Our team closely coordinated with the NMED AQB to expedite the permitting process.  

NMED DP-1620

eSPARC filed the Ground Water Discharge Permit Renewal Application with the NMED. This required close interface with the plant manager and environmental staff.

The application included:

  • Ground water discharge volume calculation and a description of the flow metering system
  • Discharge quality data for Nitrate, Total Kjeldahl Nitrogen, Total Dissolved Solids, Chloride, metals, and organic compounds
  • Surface Soil Survey and Vadose Zone Geology
  • Location map with topographic surface contours and flood zone map
  • Ground water contour map including on-site monitoring wells and construction logs for monitoring wells
  • Estimated usage and collection of SDS for chemicals used in the water treatment facilities, and cooling towers
  • Public Notice process assistance
