Does every Dallas turnaround need added mobile vapor control capacity?

No. Many turnarounds stay within your facility's existing flare and oxidizer capacity. Added mobile capacity becomes necessary when your expected stream volume from a de-inventory or purging event exceeds what your on-site system can handle, which is more common on large vessels like FCCUs or hydrocracker units.

Does the Severe ozone classification change what counts as a major source for my Dallas facility?

Yes. The major-source threshold for VOC and NOx drops to 25 tons per year under the Severe classification, down from 50 tpy before. This applies to your facility whether you're running a chemical plant or terminal in the Dallas area or a refinery, so it's worth reviewing your turnaround-related emissions against that threshold rather than assuming it only affects refining sites.

Why would I choose a flareless approach instead of routing vapor to my plant flare?

Because applicable flare-management requirements can leave you little room to absorb an unplanned load, especially during a large de-inventory event. Routing your stream to a mobile oxidizer instead avoids adding that load to your flare.

Does using a mobile thermal oxidizer during my Dallas turnaround change what I have to report to TCEQ or EPA?

Yes, in part. It changes how we document the emissions event, but your reporting obligations depend on your facility's permits and the specific event type, so this isn't a substitute for confirming what your site's own permits require.

Does a single odor complaint during my Dallas turnaround mean an automatic TCEQ violation?

No. A complaint typically leads to a site visit or investigation rather than an automatic finding, weighed against the FIDO criteria before TCEQ decides on any enforcement action.

Does mobilization timing differ between an emergency and a planned turnaround at my Dallas facility?

Yes. Planned mobilization lets us design our support around your specific vessel and stream ahead of time, while emergency response depends more on what's available and how quickly site access and permitting come together. Scheduling ahead of your outage date gives us more control over that difference.

What changed under the Refinery Sector Rule for MSS events at my Dallas-area facility?

The Refinery Sector Rule applies specifically to petroleum refineries, and it narrowed exemptions that used to apply to certain maintenance, startup, and shutdown emissions while adding stricter flare work practice standards. If you're running a chemical plant or terminal in the Dallas area, you operate under your own separate source category rules rather than this specific rule, though similar flare-management and documentation expectations can apply to you. We recommend confirming which provisions cover your facility with your environmental team before your turnaround.

What do we need to plan mobile vapor control for your Dallas turnaround?

We typically start with your vessel inventory, expected stream composition, site access details, and your target schedule. The earlier you share this, the more we can design your support around the actual job instead of a generic setup.

Is there a reason to schedule my Dallas turnaround vapor control support well ahead of my outage date?

Yes. It gives us room to work around your facility's permitting timeline and coordinate logistics before things get tight closer to the outage, rather than competing for the same resources everyone else is reserving during peak turnaround season.

Can a mobile scrubber handle the same job as a mobile thermal oxidizer during my Dallas turnaround?

No, not always. We typically recommend thermal oxidizers for high-volume vapor control, while vapor scrubbers handle specific chemistries like ammonia or targeted odor control at your site.
