Senate committee substitute makes the following changes to the 1st edition.

Changes the short title.

Deletes the provisions of the previous edition in their entirety and makes the following proposed changes.

Provides whereas clauses dealing with B. Everett Jordan Lake.

Establishes that the NC General Assembly intends to address the water quality in Jordan Lake and recognizes six items to be true, including that the lake was authorized, designed, and constructed by the federal government and, prior to impoundment, documentation shows that the federal government knew the lake would be an impaired body of water and that the design of the lake creates a situation of perpetual impairment regardless of upstream variables. Therefore, the state's existing nutrient management strategies regulating the lake basin will continue to have little or no effect on water quality improvement in the lake itself.

Directs the Environmental Management Commission (EMC), no later than October 1, 2013, to repeal the following administrative rules, 15A NCAC 02B .0262 through .0273 and 15A NCAC 02B .0311.

Repeals SL 2009-216, Part II of SL 2009-484, Section 14 of SL 2011-394, Section 12.1 of SL 2012-187, Subsections 9(c) through 9(g) of SL 2012-200, and Subsections 11(a) through 11(e) of SL 2012-201.

Establishes the Jordan Lake Study Subcommittee of the Legislative Research Commission to consider all the issues deemed relevant in addressing the water quality of Jordan Lake. Provides that five senators and five representatives will be appointed by their respective leaders to serve on the subcommittee. The subcommittee must undertake eight specified activities, including reviewing the history of Jordan Lake and its nutrient loading issues and considering the potential future conditions and uses of Jordan Lake. Findings and recommendations are to be submitted to the 2014 Regular Session of the 2013 General Assembly, Environmental Review Commission, and the Fiscal Research Division.

Directs DENR and the EMC to consult with the US Army Corp of Engineers and the US EPA to identify specified mitigation strategies.
