The Department of Environmental Services proposed to readopt Env-A 1000, Prevention, Abatement, and Control of Open Source Air Pollution, with an amendment. The section establishes requirements for open burning, fugitive dust, and firefighter instruction and training activities. Changes would delete the requirement for open burning not to create a nuisance, and provide more detail for precautions needed to prevent and control fugitive dust. There will be a public hearing February 15, 2011, and the deadline for comment is February 28. http://www.gencourt.state.nh.us/rules/register/2011/january14-11.pdf pp. 1-2.
