Limits for air pollution emissions will be met by Lehigh Cement’s new conveyor belt system

As part of a draft permit issued by the Maryland Department of the Environment, Lehigh Cement Co.’s proposed conveyor belt transportation system, which would move limestone from a New Windsor quarry to the company’s plant in Union Bridge, will meet all state and federal air quality requirements, according to reports in the Carroll County Times.

The company has been looking into mining at the New Windsor quarry for around six years, as the limestone supply at the Union Bridge quarry (next to the plant) will slowly reduce over the next decade. The company is hoping to have all the permits necessary to construct the 4.5 mile conveyor belt system by April 2014.

Regulations to be met

  • Lehigh Cement will emit no more than 22.09 t of total particulate matter and no more than 7.42 tpa of fine particulate matter with the conveyor system running at maximum production. Furthermore, the company will limit the emission of particulate matter that is 10 µm in diameter or less to a total of 10.81 t.
  • The state’s limit for respirable crystalline silica emissions will be complied with.
  • The company will meet National Ambient Air Quality Standards for ground-level concentration of particulate matter.

Company efforts to reduce pollution

Lehigh Cement Co. is undertaking various measures to reduce pollution and become more environmentally friendly. As recently reported by World Cement, Lehigh Hanson’s cement plant in Union Bridge was awarded an ENERGY STAR® by the US Environmental Protection Agency (EPA) for energy efficiency.
