Common questions

Oklahoma filing details.

Does TierSure calculate Oklahoma Tier II thresholds?
TierSure records the quantity, conversion, rule version and official citation behind each decision. For Oklahoma, the configured control is: Federal 10,000 lb general threshold and the lower of 500 lb or the chemical-specific TPQ for an EHS, subject to the state-specific controls below.
Does TierSure submit directly to Oklahoma?
TierSure prepares the reviewed filing package and recipient checklist. The authorized facility representative completes tier2 submit collection utility handoff and retains the resulting state and local receipts in TierSure.
Can I try TierSure with a Oklahoma facility?
Yes. The 14-day trial includes one facility and does not require a credit card. Core or Plus access is purchased before the final filing pack is generated.
