Section NR 446.06 - Baseline mercury emissions for major utilities

This section applies to the determination of baseline mercury emissions for major utilities.

(1) No later than October 1, 2005, the owner or operator of a major utility shall submit a report to the department that includes information to calculate the baseline mercury emissions of each combustion unit owned or operated by the major utility for calendar years 2002, 2003 and 2004, using the procedures in s. NR 446.07.

(2) After reviewing the report provided in sub. (1), the department shall determine the baseline mercury emissions for each combustion unit of the major utility. The baseline mercury emissions shall be the arithmetic average of the baseline emissions for 2002, 2003 and 2004, unless the department approves an alternative baseline requested by the major utility.

(3) In the report required under sub. (1), an owner or operator may request that the department determine an alternative baseline if the 3 years are not representative of the source's normal operations and maintenance schedule. This request shall include sufficient information to demonstrate that an alternative baseline is appropriate, a proposed alternative baseline, and information sufficient to document how the proposed alternative baseline was determined.

(4) No later than January 1, 2007, the department shall provide written notification to each owner or operator who submitted a report under sub. (1) of the department's determination of the baseline mercury emissions for each combustion unit of the major utility.
