Current through Register Vol. 49, No. 13, September 23, 2024

Subpart 1. Operation of concrete manufacturing plant control equipment.

Unless otherwise allowed in a state or part 70 permit, emissions during cementitious material receiving from cement silos and other cementitious material storage devices shall pass through a fabric filter. For concrete manufacturing plants in operation on December 2, 1998, the owner or operator must install control equipment no later than December 2, 1999. For concrete manufacturing plants not in operation on December 2, 1998, the control equipment must be installed prior to operation of any concrete manufacturing plant.

Subp. 2. Operation and maintenance of fabric filter control equipment.

The owner or operator of a concrete manufacturing plant shall perform the following on each piece of control equipment required in subpart 1:

A. properly operate and maintain the control equipment to function as it was designed. Proper operation and maintenance includes effective performance, adequate funding, and adequate operator staffing and training;

B. thoroughly conduct an internal and external inspection of control equipment at least annually, which often requires shutting down temporarily, and maintain a record of the activities conducted in the inspection including the activities completed, the date the activity was completed, and any corrective action taken; and

C. maintain a record of parts replaced, repaired, or modified.

Subp. 3. Monitoring of fabric filter control equipment.

During cementitious material receiving, the owner or operator of a concrete manufacturing plant, or a designee, shall observe the outlet of each piece of control equipment required in subpart 1 for any visible emissions once each day cementitious material is received, and record the date and time period during which the observation was made and whether or not any visible emissions were observed. If visible emissions are observed, the owner or operator, or a designee, shall take all practical steps to modify operations to reduce the emissions and shall take corrective action to eliminate visible emissions prior to the following business day. The commissioner may require feasible and practical modifications in the operation to reduce emissions of air pollutants.

Subp. 4. Record retention.

The owner or operator shall maintain the records required by this part for a minimum of five years from the date the record was made. The owner or operator shall maintain records for the current calendar year of operation at the concrete manufacturing plant. For all years prior to the current calendar year, the owner or operator shall maintain records at either the concrete manufacturing plant or at an office of the owner or operator of the concrete manufacturing plant.
