Challenge

Since 2011, Apex has been helping this oil and gas client address their air permitting and compliance needs for over 300 sites including well sites, compressor stations, dehydration plants, and stabilizers in the Eagle Ford Basin.

Specifically, their challenges include the following:

  • Identifying aggregation issues in accordance with the TCEQ’s Senate Bill (SB) 1134
  • Identifying the fugitive counts for their operations
  • Conducting hydrogen sulfide (H2S) and sulfur dioxide (SO2) impacts evaluations for sour sites
  • Conducting impacts evaluations using advanced air dispersion modeling (AERMOD) for stabilization plants.

Solution

Our services include conducting process modeling using ProMax, calculating sitewide emissions, identifying the permitting mechanism under the Texas Commission on Environmental Quality’s (TCEQ’s) New Source Review Program, conducting National Ambient Air Quality Standard (NAAQS) impacts assessment using SCREEN3 or AERMOD modeling, preparing air permitting packages, and addressing TCEQ’s follow-up questions. TCEQ’s air permitting mechanisms used for permitting these facilities include Permit by Rule (PBR) and Non‑Rule Standard Permit (NRSP) for oil and gas facilities. Over the years, Apex has prepared over 1,000 PBR and NRSP registration and revision packages for this client.

During the course of our project work, we have also helped the client evaluate the permitting mechanism for over 150 audit privilege sites in Texas and implement the corrective actions by submitting the air permit applications for all sites within the specified timeframe.

Results

Across all assets, our client aspires to be 100% compliant with applicable laws, regulations and internal procedures. As we continue to work directly with their operational divisions help them protect our natural resources, Apex is consistently praised by their management and associates for our quick response time and our understanding of their assets and objectives.
