Standards and criteria.
By October 1, 2013, the Environmental Quality Board, in consultation with local units of government, shall develop model standards and criteria for mining, processing, and transporting silica sand. These standards and criteria may be used by local units of government in developing local ordinances. The standards and criteria shall be different for different geographic areas of the state. The unique karst conditions and landforms of southeastern Minnesota shall be considered unique when compared with the flat scoured river terraces and uniform hydrology of the Minnesota Valley. The standards and criteria developed shall reflect those differences in varying regions of the state. The standards and criteria must include:
(1) recommendations for setbacks or buffers for mining operation and processing, including:
(i) any residence or residential zoning district boundary;
(ii) any property line or right-of-way line of any existing or proposed street or highway;
(iii) ordinary high-water levels of public waters;
(v) designated trout streams, class 2A water as designated in the rules of the Pollution Control Agency, or any perennially flowing tributary of a designated trout stream or class 2A water;
(vii) wellhead protection areas as defined in section
103I.005;
(viii) critical natural habitat acquired by the commissioner of natural resources under section
84.944; and
(ix) a natural resource easement paid wholly or in part by public funds;
(2) standards for hours of operation;
(3) groundwater and surface water quality and quantity monitoring and mitigation plan requirements, including:
(i) applicable groundwater and surface water appropriation permit requirements;
(ii) well-sealing requirements;
(iii) annual submission of monitoring well data; and
(iv) stormwater runoff rate limits not to exceed two-, ten-, and 100-year storm events;
(4) air monitoring and data submission requirements;
(5) dust control requirements;
(6) noise testing and mitigation plan requirements;
(7) blast monitoring plan requirements;
(8) lighting requirements;
(9) inspection requirements;
(10) containment requirements for silica sand in temporary storage to protect air and water quality;
(11) containment requirements for chemicals used in processing;
(12) financial assurance requirements;
(13) road and bridge impacts and requirements; and
(14) reclamation plan requirements as required under the rules adopted by the commissioner of natural resources.

Silica sand technical assistance team.
By October 1, 2013, the Environmental Quality Board shall assemble a silica sand technical assistance team to provide local units of government, at their request, with assistance with ordinance development, zoning, environmental review and permitting, monitoring, or other issues arising from silica sand mining and processing operations. The technical assistance team may be chosen from representatives of the following entities: the Department of Natural Resources, the Pollution Control Agency, the Board of Water and Soil Resources, the Department of Health, the Department of Transportation, the University of Minnesota, the Minnesota State Colleges and Universities, and federal agencies. A majority of the members must be from a state agency and all members must have expertise in one or more of the following areas: silica sand mining, hydrology, air quality, water quality, land use, or other areas related to silica sand mining.
