Oil and Gas Comprehensive Environmental Air Audit
Client: Oil and Gas Company With Production Pads and Saltwater Disposal Facilities
Challenge
An oil and gas company recently acquired 35 existing facilities in Converse County, Wyoming. The facilities ranged from multi-well production pads to saltwater disposal facilities. The client wanted to ensure that each facility was in compliance with all state and federal air quality rules and regulations. A complete equipment inventory needed to be conducted at each facility, and then that equipment needed to be reviewed for air quality permitting requirements and potential applicability for New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAP).
Solution
Altamira developed and executed a comprehensive plan to complete an environmental audit for the client’s 35 facilities. The audit scope included the following key components:
- On-site Facility Assessments: Site visits were conducted at each facility to develop a complete inventory of all equipment. Detailed information was collected for each emission unit, including photographs, capacities, heat ratings, horsepower, manufacturer dates and serial numbers. At the client’s request, all pneumatic devices were also documented, including associated bleed rates.
- Permitting History Review: A thorough review of the permitting history for each facility was performed. This effort included reconciling permitted equipment with equipment observed during site visits. Additionally, permitted throughput limits were compared against actual facility throughputs to confirm compliance with permit requirements.
- Compliance Reporting Evaluation: Altamira conducted an extensive review of each facility’s compliance reporting history. This included verifying that required submissions — such as engine stack testing reports and operating permit applications — were completed accurately and submitted on time.
- Regulatory Applicability Analysis: Applicability determinations were performed in accordance with state and federal air quality rules and regulations. Equipment such as storage tanks, compressors, pneumatic devices and fugitive emission sources were evaluated for applicably under New Source Performance Standards (NSPS), including subparts OOOOa and OOOOb (Standards of Performance for Crude Oil and Natural Gas Facilities).
Following completion of the audit, Altamira prepared a comprehensive audit findings summary for the client to submit to the state as a one-time deliverable.
Results
Upon completion of the environmental audit, the client engaged Altamira to prepare the 25 permit modifications identified as necessary based on the audit findings. Altamira has continued to support the client’s Wyoming air quality permitting and compliance needs, establishing a strong, ongoing partnership. Through this collaboration, Altamira consistently delivers high-quality air permitting and compliance services, helping the client maintain regulatory compliance and operational efficiency.
