Streamlined Rules and Reduced Fees for Rock Crushers in Effect
On October 1, 2010, NHDES adopted revised rules regarding non-metallic mineral processing plants, commonly known as rock crushing plants or rock crushers. The revised rules are intended to protect air quality in New Hampshire, as well as simplify the air permitting process for these source types. The rules are codified in NH Code of Administrative Rules Env-A 2800.

Who is affected?

  • All owners and operators of non-metallic mineral processing plants, defined as any combination of equipment used to grind or crush any non-metallic mineral, such as stone, sand, gravel, clay, rock, salt, and vermiculite.
  • Municipal officials who interact with and/or are responsible for rock crushing plants in their towns.

Administrative Rules
Env-A 2800 - Sand & Gravel Sources; Non-Metallic Mineral Processing Plants; Cement & Concrete Sources - effective 10-1-2010
