ODNR's Division of Oil and Gas Resources Management (ODNR-DOGRM), has primary regulatory authority over oil and gas drilling activity in Ohio, including regulations for well construction, siting, design and operation. regulates disposal of brine (see note below) and drilling fluids from oil and gas drilling/production. ODNR regulates Class II underground injection wells used for disposal of waste fluids from oil and gas drilling/production operations and transporters hauling these fluids in Ohio
Ohio EPA’s water quality certification requirements help reduce impacts to wetlands, streams, rivers or other waters of the state from the construction of a drill site. Ohio EPA also regulates sources of air emissions, and may require air permits for some of the equipment at the drill site. Finally, any solid waste sent off-site for disposal must be properly managed, either at a solid waste landfill, or beneficially reused, as authorized by Ohio EPA’s Division of Materials and Waste Management (DMWM). A summary of the regulatory authority between ODNR and Ohio EPA is provided in Table 1.
Note:“Brine” includes all saline geological formation water resulting from, obtained from, or produced in connection with the exploration, drilling, or production of oil or gas, including saline water resulting from, obtained from, or produced in connection with well stimulation or plugging of a well. (R.C. 1509.01(U)).
Together, the Marcellus and Utica Shale regions extend across New York, Pennsylvania, Maryland, West Virginia, Ohio and portions of Kentucky and Tennessee. The deposits sit between 7,000 and 12,000 feet below ground.
Both are important geologic formations because they hold large reserves of natural gas. Researchers estimate the Marcellus Shale alone could contain as much as 363 trillion cubic feet of natural gas, enough to satisfy U.S. energy demands for about 14 years.
Most drilling is now occurring in the Marcellus Shale region of Pennsylvania, with growing interest in West Virginia and New York. Because the Marcellus Shale is much thinner on its western edge, Ohio is experiencing far less Marcellus Shale drilling than other states. However, Ohio will likely see a significant increase in future drilling, as much of the state sits over the Utica Shale formation, which experts also predict holds large natural gas reserves and potentially oil.
Natural gas is extracted from the shale through a two-step process of horizontal drilling and hydraulic fracturing. To start, a production well is drilled thousands of feet downward and then gradually angled out horizontally through the shale deposit. The well is drilled horizontally to maximize the ability to capture natural gas once the shale is hydraulically fractured.
After the well is drilled, a mixture of water, sand and chemical additives is injected at very high pressure to fracture the shale. This part of the process, called hydraulic fracturing (or “fracing”) is a technique used in the oil and gas industry since the 1950s. The sand keeps the fractured shale open and serves as a conduit for extracting the natural gas. The chemical additives reduce potential problems during drilling and gas production, such as bacterial build-up and the formation of scale, mineral deposits and rust.
It can take up to four million gallons of fresh water to fracture a single well. The water used in the fracturing process usually comes from a stream, river, reservoir or lake near the drill site, or in some cases, from a local municipal water plant.
Most of the water used to fracture the shale remains trapped thousands of feet underground after it is injected. However, internal pressure in the geologic formation forces some of the water (around 15-20 percent of the total volume injected) back to the surface through the well bore.
Most of this "flowback" or "frac" water comes back to the surface within seven to 10 days after it is injected. Flowback water is stored temporarily in lagoons or tanks before being sent off-site for disposal. It is usually transported off-site by truck, although some companies are exploring rail transportation as an options.
Drilling companies send brine and flowback water to disposal facilities that have permits to inject fluids thousands of feet underground into deep injection wells (called Class II wells).
Because of disposal costs, some drilling companies are recycling and reusing flowback water from one drill site to another. Having multiple drill sites in close proximity makes it more cost-effective to reuse flowback water. The concentration of iron, bacteria, suspended solids and other contaminants in flowback water is another factor in determining whether it can be reused.
Citizens are becoming more aware and concerned about potential impacts of drilling activity on them, the environment and their communities.
Because Ohio has a significant number of permitted Class II underground injection control wells, many drilling companies have been transporting brine and flowback water into Ohio for deep-well disposal.Flowback water picks up minerals from the shale formation, including iron, calcium, magnesium, barium and sulfur. It may contain low levels of naturally occurring radioactive elements such as radium. It also contains high concentrations of total dissolved solids (TDS), including chlorides, sodium and sulfates. High levels of TDS in streams, rivers or lakes can impair water quality and kill aquatic life.ODNR has the exclusive authority for brine disposal in Ohio. Ohio prohibits the direct discharge of brine or flowback water into waters of the state. Ohio is not authorizing the disposal of brine or flowback water at municipal wastewater sewage plants (also called publicly owned treatment works or POTWs).Brine and flowback water disposed of in Ohio must be sent to an ODNR-permitted Class II injection well, unless granted an exemption by ODNR. Where feasible, recycling flowback water is strongly encouraged.Under ODNR’s laws, brine may be suitable for road surface application, if certain conditions are met. Other fluids from well drilling, including flowback water, cannot be applied to roadways. For more information on brine management options, contact ODNR, DMRM.
The Ohio EPA, ODNR and other technical experts familiar with hydraulic fracturing do not have data showing a risk of ground water contamination from brine migrating thousands of feet from the Marcellus or Utica Shale fractures up into drinking water aquifers much closer (hundreds of feet) to the earth’s surface.There is the potential, although unlikely, for contamination of drinking water wells because of problems occurring closer to the surface.Gas and oil can migrate from a production well into an aquifer if a well casing is damaged, leaking or poorly constructed. Natural gas can also enter aquifers from old, abandoned oil and gas wells that are unplugged or poorly plugged. A new water well that is drilled can penetrate gas-rich organic shales or coal seams at shallow depths, allowing gas to enter the well. Buried organic deposits from old swamps or landfills may also release natural gas into soils overlying aquifers.It’s important to know that there have been thousands of oil and gas production wells drilled throughout Ohio without significant adverse impacts to drinking water resources.If you do, however, suspect any problems with your drinking water well as a result of any oil/gas drilling activities in your area, contact the Ohio Department of Natural Resources, Division of Oil and Gas Resources Management at (614) 265-6633.The Ohio EPA, ODNR and Ohio Department of Health (ODH) have also developed the Recommendations for Water Well Sampling Before Oil and Gas Drilling fact sheet that provides a basic overview for private and/or public well owners who are considering collecting samples prior to oil and gas drilling (including the Marcellus and Utica shale deposits) in areas near their properties.
The process of drilling a well begins with a lease agreement between the producing company and one or more landowners that make up a drilling unit. It is important for a landowner approached for a mineral rights lease to be aware of all the conditions of the lease that allow the producer to drill on their land.Ohio EPA’s and ODNR-DOGRM’s regulations DO NOT cover private property lease agreements, and we cannot provide homeowners with any specific guidance on this topic. As a starting point for general information on leases, see ODNR’s website, “Landowners and Leasing for Oil and Gas in Ohio.”
