Workshops Offered on Rule Changes for Rock Crushing Plants
Free Workshops Offered in Concord and Lincoln

Concord, NH - New Hampshire Department of Environmental Services will offer two morning workshops for non-metallic mineral processing plants, commonly known as rock crushing plants or rock crushers.

If you are involved in gravel pit operations or any other type of rock crushing (non-metallic mineral processing plants that grind or crush any non-metallic mineral, such as stone, sand, gravel, clay, rock, salt, and vermiculite), you should attend this workshop to learn about the new rules and how they apply to you and your business. Municipal officials may want to attend this if they have any rock crushing operations in their municipality.

The workshops will cover the newly adopted Env-A 2800 non-metallic mineral processing rules and the National Emission Standards for Hazardous Air Pollutants: Reciprocating Internal Combustion Engines, 40 CFR 63, Subpart ZZZZ.

Workshops will be on Wednesday, January 26 in Concord and Tuesday, February 8 in Lincoln.

To register, contact Sara J. Johnson, Small Business Technical Assistance Program, (603) 271-1379 or For more information on the new Env-A 2800 rules for rock crushers, visit
