ADM Milling Co. is planning a $29 million expansion at its plant on Indianapolis’ southeast side that includes construction of a six-story building and new milling equipment.

The subsidiary of Decatur, Ill.-based Archer Daniels Midland Co., a global food-processing and commodities-trading corporation, is seeking a four-year personal and property tax abatement from the city to help offset the cost.

The city’s Metropolitan Development Commission will consider the abatements Wednesday.

ADM said the expansion will help it retain 53 workers at its local operations at 845 Bethel Ave.

ADM says it will spend nearly $11 million to build the facility to increase its wheat-processing production from 900 tons daily to more than 1,300 tons.

The company also plans to invest $18 million in new manufacturing equipment to clean, sift, roll and mill wheat.

As a result of the investments, the ADM mill will become one of the largest flour mills in North America, according to a city filing.

MDC staff recommends approval of the four-year abatement. The company should expect to save a combined $519,000 in personal and real property taxes during the abatement period and pay about $336,000.

The new building and equipment should add more than $11 million to Indianapolis’ tax base, the city said.
