3.14 	Sec. 2. Minnesota Statutes 2008, section 115B.40, subdivision 6, is amended to read:
3.15 		Subd. 6.Commissioner; duties. (a) If the owner or operator of a qualified facility 
3.16 	that is subject to the requirements of subdivision 4, paragraph (a), fails to comply with 
3.17 	subdivision 4, paragraph (a), clause (1) or (2), the commissioner shall:
3.18 	(1) undertake or complete closure activities at the facility in compliance with the 
3.19 	solid waste rules in effect at the time the commissioner takes action under this clause; and
3.20 	(2) undertake or continue postclosure care at the facility as required under 
3.21 	subdivision 2.
3.22 	(b) If a facility has been properly closed under subdivision 4, but the applicable 
3.23 	closure requirements are less environmentally protective than closure requirements in the 
3.24 	solid waste rules in effect on January 1, 1993, the commissioner shall determine whether 
3.25 	the facility should be closed to the higher standards and, if so, shall undertake additional 
3.26 	closure activities at the facility to meet those standards. The commissioner may determine 
3.27 	that additional closure activities are unnecessary only if it is likely that response actions 
3.28 	will be taken in the near future and that those response actions will result in removal or 
3.29 	significant alteration of the closure activities or render the closure activities unnecessary.
3.30 	(c) Notwithstanding subdivision 4, for a qualified facility defined under section 
3.31 	115B.39, subdivision 2, paragraph (l), clause (3), the commissioner must assume financial 
3.32 	responsibility for all postclosure care and contingency actions and any other related 
3.33 	actions required at the facility.

3.34 	EFFECTIVE DATE. This section is effective the day following final enactment.
