COLUMBUS, Ohio – The Ohio Environmental Protection Agency is considering a recent permit that could allow data centers across the state to discharge wastewater directly into Ohio’s rivers, streams, and even Lake Erie. The proposal, currently in draft form, has sparked concern among environmental groups who fear the potential impact on water quality and aquatic ecosystems. The move comes as Ohio experiences a surge in data center construction, driven by the growing demand for cloud computing and artificial intelligence.
The proposed permit would operate under a “one-size-fits-all” approach, applying to all data centers regardless of their size, water usage, cooling technology, or location. Critics argue this lack of specificity could lead to inadequate oversight and increased pollution. The Great Lakes Environmental Law Center, among others, is raising alarms about the potential consequences for drinking water sources and the health of Ohio’s waterways, particularly Lake Erie, which already faces challenges from nutrient pollution and harmful algal blooms. The core issue revolves around data center wastewater discharge and its potential effects.
What the Proposed Permit Would Allow
According to the draft National Pollutant Discharge Elimination System (NPDES) permit, data centers would be permitted to release wastewater and stormwater. The concern centers on the nature of this wastewater, which can be significantly warmer than ambient water temperatures and may contain chemicals used in cooling equipment. The permit, as currently proposed, would:
- Treat all data centers uniformly, regardless of individual characteristics.
- Allow for the discharge of pollutants from cooling chemicals with limited monitoring requirements.
- Potentially exacerbate harmful algal blooms by allowing thermal pollution and failing to set limits for nutrients like nitrogen and phosphorous. Data centers can concentrate these nutrients through evaporative cooling processes.
- Increase costs for communities needing to treat more contaminated water.
- Reduce public transparency and accountability regarding discharge practices.
- Require minimal monitoring for contaminants.
Environmental advocates point out that more than half of Ohioans rely on surface waters for their drinking water, and Lake Erie alone supports a multi-billion dollar economy through fisheries, tourism, and shipping. Protecting these resources is seen as crucial.
Concerns About Thermal Pollution and Nutrient Levels
A key concern is thermal pollution – the discharge of water that is warmer than the receiving body of water. Elevated water temperatures can harm aquatic life and contribute to the growth of harmful algal blooms. The proposed permit does not adequately address this issue, according to critics. The permit reportedly lacks specific limits for nitrogen and phosphorous, nutrients that already contribute to algal blooms in Lake Erie and the Ohio River. Data centers utilize freshwater and can concentrate existing nutrients through evaporative cooling, potentially worsening the problem. The Ohio EPA’s draft permit is facing scrutiny for these omissions.
Data Center Growth and Water Usage in Ohio
The debate over the wastewater permit coincides with a significant increase in data center construction across Ohio. These facilities require vast amounts of water for cooling purposes. Adams County, in particular, is seeing substantial investment in data centers, raising concerns about the strain on local water resources and the potential for increased energy consumption. One data center in Adams County is projected to be among the largest power consumers in the state.
Stakeholder Reactions
Environmental groups are urging the Ohio EPA to reconsider the proposed permit and adopt stricter regulations. They advocate for a more tailored approach that takes into account the specific characteristics of each data center and implements robust monitoring requirements. They also emphasize the need for greater public transparency and opportunities for input. The Ohio EPA has not yet responded to specific criticisms, but maintains it is evaluating all feedback received during the public comment period.
Next Steps and Public Input
The Ohio EPA is currently accepting public comments on the draft permit. The public comment period is open until [Date not specified in sources – unconfirmed]. Interested parties can submit comments online through the Ohio EPA’s website or attend a public hearing. The agency is expected to review all comments before finalizing the permit. The final decision will likely have significant implications for the future of data center development and water quality in Ohio.

This situation highlights the growing tension between economic development and environmental protection in Ohio. As the state seeks to attract new industries, it faces the challenge of balancing economic growth with the need to safeguard its natural resources. The outcome of this debate will likely set a precedent for future data center projects and other industrial developments across the state.
