5 Overview of Rules Process: Tentative Rule Schedule Request for Comments: 7/26/10, 10/17/11 Dual Notice (DN) – December 2012 Final Adoption: with hearing - 6 months after DN w/o hearing - 3 months after DN 5

6 Outline Siting Issues to Discuss: 5 foot separation to groundwater Soil permeability requirement Pad requirements Compost Maturity 500 feet of horizontal separation 6

7 5’ separation to the groundwater subp. 3: An owner or operator may not establish or construct a source-separated waste composting facility in the following areas: (B) within five feet of a water table The water table is defined in Minn. R Generally top of saturated zone Perched groundwater tables will be considered on a site by site basis 7

8 Soil Permeability Requirement subp. 8(G): at a minimum, the site should have a net of five feet of native soil with a maximum permeability of 1.4 x cm/sec The permeability throughout the entire 5 feet of soil must be less than 1.4 x cm/sec If there is more than 5 feet of soil, the net permeability of the soil must be less than 1.4 x cm/sec 8

9 Pad Requirements Is there more than 5’ of native soil to the groundwater?? Does that 5’ of soil have a net permeability less than 1.4x10 -4 cm/sec?? YES NO YES No pad required NO Pad required Option #1: Soil Pad Place at least 1’ of soil with a permeability of less than 1x10 -5 cm/sec (must have at least 5’ to groundwater) Option #2: Geomembrane Install liner system defined in subp. 4 Possible Option #3: Hard Surface Concrete or asphalt pad

10 Pad Requirements If a pad is required, Must be at least 1’ of soil with a permeability less than 1 x cm/sec There must be at least 5’ of soil between the final grade and groundwater Tipping area, active composting and screening must be done on a pad Storage of mature compost does not require a pad 10

11 Compost Maturity Maturity is defined in Minn. R % decomposition as determined by an ignition-loss analysis and one method approved by the commissioner including, but not limited to: Solvita (7-8) C/N ratio (10:1 to 20:1) Other MPCA approved methods 11

12 500’ separation to neighbors subp. 3: An owner or operator may not establish or construct a source-separated waste composting facility in the following areas: (C) A minimum of 500 feet horizontal separation distance from the facility to the nearest… Requires 500 feet between all permitted waste activity areas and the nearest neighbor. Tipping Area Screening Area Compost Pad Finish Compost Storage Contact Water Treatment 12

13 Stakeholder Input 13

14 Variance Process Minn. R Applicant may apply for variances for: Grounds of economic burden Grounds that compliance is not technically feasible 14

15 Summary/Conclusions/Next Steps 15 Send comments to 2/10/12 meeting to Yolanda Letnes no later than 2/17/12
