Texas toll blending: what to check at a Texas site
Updated
A toll blender in Texas works under the same federal rules as any US site and under the state's own air permitting by the Texas Commission on Environmental Quality.
Talk to a specialist Who owns the materials, who carries the price risk, and the clauses to settle before a formulation leaves your building.
The federal rules are the same
Chemical substances in commerce, worker safety and pesticide production are federal: the TSCA inventory, OSHA's standards and FIFRA's establishment registration apply to a Texas site exactly as anywhere else. The guides on agricultural toll blending and distillation cover the parts that most often decide a site.
Texas air permits
TCEQ's air permits division issues New Source Review permits, including permits by rule, for new or modified sources of air emissions, and Title V operating permits for major and certain other industrial sites. TCEQ also requires permittees whose permits carry no regular reporting to report the operational status of the permitted activity each year.
Ask a Texas blender which authorization covers the equipment that would run your product, and whether adding your product is within it or needs a change.

Looking up a site's permits
TCEQ publishes pending NSR and Title V applications and notices and a route to check application status and find permit documents. Reading a blender's own permit before a site visit tells you what the site is authorized to run.
