OH SB181

Establishes new regulatory framework for underground mining of limestone and dolomite in Ohio, requiring operators to obtain permits, submit mining plans, maintain $1 million liability insurance, and comply with safety standards including roof control plans

Increases severance tax rates: limestone/dolomite rises from 2 cents to 2.5 cents per ton, sand/gravel from 2 cents to 2.5 cents per ton, and clay/sandstone/shale/gypsum/quartzite from 1 cent to 1.5 cents per ton

Adds new 0.25 cents per ton tax on limestone and dolomite mined by underground methods, with revenue credited to a new Underground Minerals Mining Fund for addressing surface impacts of inactive underground mining operations

Eliminates permit expiration dates for surface, underground minerals, and in-stream mining permits, replacing them with mandatory reviews by the Division of Mineral Resources Management at least every five years

Limits township and county zoning authority over underground minerals mining on land already permitted for surface mining, and prohibits local governments from requiring mine operators to file surety bonds, performance bonds, or closure bonds
