MN SF2604

Amends Minnesota Statutes 2008, section 116.85, subdivision 1a, to modify mercury testing requirements for incinerator facilities with mercury emission limits.

Allows hospital waste incinerators with design capacity less than 3,000,000 BTU's per hour to use mercury segregation practices as an alternative to stack testing if approved by the commissioner.

Permits facilities burning greater than 30 percent refuse-derived fuel by weight to conduct mercury stack testing annually instead of quarterly, unless a previous test exceeded permit limits.

Enables facilities demonstrating mercury emissions below 50 percent of permitted limits for three consecutive years to reduce testing frequency to once every three years or per federal requirements, whichever is more stringent.

Applies less frequent testing requirements to new units at facilities that previously met the standards, provided the new unit demonstrates compliance below 50 percent of permitted limits for one year.
