How to file the Ohio Class II disposal well quarterly report

If you own a Class II saltwater disposal well in Ohio, you owe ODNR a report every quarter and a fee statement every year. Here's what goes in each, when they're due, and how the per-barrel fee works.

The daily records behind the report

Ohio's rule requires disposal well owners to continuously monitor and record injection pressures and injection volumes for each well on a daily operational basis, and to keep that data for the life of the well. ODNR can ask for it at any time. The quarterly report is built from these daily records plus your shipment log.

What the quarterly report contains

Within 45 days after each calendar quarter ends, the owner submits a report on ODNR's form with four things:

1. Every shipment of brine or other waste received: its source, volume in barrels and delivery date.
2. Monthly totals: barrels received in each month of the quarter.
3. Fee breakdown: the delivered volumes summarized by which fee applies to them.
4. Pressures: the average and maximum injection pressure for each month of the quarter.

Ohio law also has disposal well owners report shipment information electronically each quarter, and ODNR can require the report in an electronic format.

Quarterly deadlines

The fourth-quarter report and the annual fee statement land in the same week in February, so plan for both.

The annual disposal fee

Ohio charges a fee on every barrel delivered to a disposal well, and the well owner collects it on the state's behalf:

• 5 cents a barrel for brine produced in the district where the well sits or an adjoining district.
• 20 cents a barrel for brine from anywhere else, including out of state.
• The fee applies to no more than 500,000 barrels per well per calendar year.
• The owner may keep up to 3% of what it collects.

By February 15 each year, the owner files a statement of the barrels injected the prior year and the fee collected, and sends the fee with it. ODNR's Disposal Fee form uses one form per injection well and calculates the 20-cent volumes first. The form goes to ODNR Division of Oil & Gas Resources Management, 2045 Morse Road, F-2, Columbus, OH 43229-6693, referenced "Disposal Fee", with a check payable to the Ohio Department of Natural Resources, Division of Oil and Gas Resources Management.

A quick fee example

A disposal well takes 120,000 barrels in a year: 90,000 from its own district and 30,000 from a district farther away.

This only works if every shipment in your log records where the brine came from. That's why the source on each load matters as much as the barrels.

Where operators get tripped up

• Shipments without a source. A load with no origin can't be put in the right fee bracket.
• Pressures pulled from memory. The report asks for each month's average and maximum, which only works if the daily readings were written down.
• No proof of delivery. Send filings in a way that gives you a receipt, and keep it. A report the state never received is treated as not filed.
