5 foot separation to groundwater
500 feet of horizontal separation
Soil permeability requirement
Pad requirements
Compost Maturity 6
5’ separation to the groundwater7035.2555 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. 7035.0300Generally top of saturated zonePerched groundwater tables will be considered on a
site by site basis
7
500’ separation to neighbors7035.2555 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 residence, place of business or public contact area. Requires 500 feet between all permitted waste
activity areas and the nearest neighbor.
8
Soil Permeability Requirement7035.2836 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 10-4 cm/sec
The permeability throughout the entire 5 feet of soil must be less than 1.4 x 10-4 cm/sec
If there is more than 5 feet of soil, the net permeability of the soil must be less than 1.4 x 10-4 cm/sec
MPCA is considering using Soil Type/Classification instead of specific permeability
9
Pad RequirementsIs 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??
YE
S
NO
YE
S
No pad required
NO
Option #1: Soil PadPlace at least 1’ of soil with a permeability of less than 1x10-5cm/sec (must have at least 5’ to groundwater)
Option #2: GeomembraneInstall liner system defined in 7035.2836 subp. 4
Pad required
No Siting Allowed
Pad RequirementsIf a pad is required,
Must be at least 2’ of soil with a permeability less than 1 x 10-5 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
11
Compost MaturityMaturity is defined in Minn. R. 7035.283660% 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
