Midstream operations occupy a specific and often underappreciated position in the oil and gas regulatory landscape. Gathering systems, compressor stations, processing facilities, and transmission pipelines are subject to a permitting framework distinct from upstream production operations, and operators who approach midstream permitting with an upstream mindset consistently encounter problems that delay projects and create compliance exposure.
The most costly permitting mistakes are almost always preventable. They result not from bad intentions but from a misunderstanding of how midstream facilities are classified, which regulatory pathways apply, and what the reporting obligations look like once a facility is operating. Here is what midstream operators most commonly get wrong.
Misclassifying the Facility and Choosing the Wrong Permit Pathway
Midstream facilities, particularly compressor stations, often aggregate emissions from multiple sources at a single site. The classification of that site as a major or minor source under the Clean Air Act determines the permit pathway, emission limits, reporting requirements, and the operational flexibility the operator will have going forward. Getting this classification wrong at the outset has cascading effects.
An operator who underestimates the potential to emit at a compressor station and applies for a minor source permit when the facility should be classified as a major source is not in violation at the permitting stage. The violation occurs when the facility operates at levels inconsistent with the permit obtained. Correcting a permit classification after the fact requires a new application, a potential shutdown of operations during the review period, and, in some cases, disclosure of the period during which the facility operated without proper authorization.
EOSolutions evaluates each midstream facility against both current and projected operational parameters to ensure that the selected permit pathway is appropriate for what the facility will actually do, not just what it is doing on day one.
Incomplete Equipment Inventories in Permit Applications
A midstream permit application must account for all regulated equipment at the facility. Compressor engines, combustion units, storage vessels, pneumatic devices, and fugitive emission sources all contribute to the facility’s total potential to emit. Permit applications that fail to include all equipment sources are both legally deficient and practically problematic because equipment not covered by the permit is not authorized to operate.
This is a more common problem than it should be. Facility configurations change during construction and commissioning, and applications submitted based on early design documents may not reflect the equipment ultimately installed. EOSolutions coordinates with operations teams throughout the design and construction process to ensure permit applications reflect the actual facility configuration, not the one that existed six months before startup.
Failing to Account for Aggregation Rules
Multiple midstream facilities in close proximity that share common ownership or control may be treated as a single facility for permitting purposes under EPA and TCEQ aggregation rules. Operators who permit each facility to operate independently, without considering aggregation, may find that the combined potential to emit across facilities triggers major source thresholds that none of the individual facilities would meet on their own.
Aggregation analysis requires a detailed understanding of the applicable regulatory tests and the specific facts of each situation. It is also an area where the rules have evolved and continue to be interpreted through regulatory guidance and enforcement decisions. EOSolutions stays current on aggregation rules and applies that analysis at the earliest stage of facility planning, before permit applications are submitted and before the consequences of an aggregation error are locked in.
Underestimating Post-Permit Reporting Obligations
Obtaining the permit is not the end of the compliance obligation. Midstream operators are subject to ongoing reporting requirements, including annual emissions inventories, deviation reports for any exceedances of permit conditions, and federal reporting obligations under programs such as the NSPS and the air toxics standards. These obligations begin on day one of operations and continue for the life of the facility.
Operators who do not build the compliance infrastructure to meet these obligations before startup consistently find themselves behind from the beginning. Missing a reporting deadline is a separate violation from any underlying emissions issue, and late or inaccurate reports attract regulatory scrutiny that is difficult to move past. EOSolutions helps midstream operators build the reporting systems, tracking tools, and compliance calendars that make ongoing obligations manageable rather than overwhelming.
How EOSolutions Supports Midstream Operators
EOSolutions provides permitting, compliance, and regulatory consulting services to midstream operators across Texas and the broader oil- and gas-producing regions. Our team has worked on both the regulatory agency and operator sides, which gives us a practical understanding of how permit applications are reviewed, what reviewers look for, and how to present a facility in a way that moves the process along efficiently.
We work with operators from the earliest stages of facility planning through startup, ongoing operations, and any regulatory reviews or enforcement actions that arise. Midstream operators who work with EOSolutions get permits that accurately reflect their operations, reporting systems that keep them current on their obligations, and a compliance partner who thinks ahead rather than reacts.
