species, or weeds.
C.Fully mixed BSM shall be tested prior to installation and meet the
following criteria:
1.P-Index of less than 30
2.pH of 5.5-6.5. Should pH fall outside of the acceptable range, it
may be modified with lime (to raise) or iron sulfate plus sulfur (to
lower). The lime or iron sulfate must be mixed uniformly into the
BSM prior to use in the bioretention facility.
3.Cation Exchange Capacity (CEC) greater than 10
4.Phosphorous (Phosphate, P2O5) not to exceed 69 ppm

piles will not be allowed. Mixing of the BSM to a homogeneous
consistency shall be done to the satisfaction of the Owner.

1.BSM shall consist of 10-20% leaf compost by volume.
2.Leaf compost shall consist of Class 1 organic leaf compost
consisting of aged leaf mulch resulting from biological degradation
and transformation of plant-derived materials under controlled
conditions designed to promote aerobic decomposition.
3.The material shall be well composted, free of viable weed seeds
and contain material of a generally humus nature capable of
sustaining growth of vegetation, with no materials toxic to plant
growth.

c.Moisture content shall be between 35 and 50 percent
d.Maturity greater than 80 percent (maturity indicator expressed
as percentage of germination/vigor, 80+/80+)
e.Maturity indicator expressed as Carbon to Nitrogen ration < 12
f.Maturity indicator expressed as AmmoniaN/NitrateN Ratio <4
g.Minimum organic matter shall be 40 percent dry weight basis
h.Soluble salt content shall be no greater than 5500 parts per
million or 0-5 mmhos/cm
i.Phosphorus content shall be no greater than 325 parts per
million
j.Heavy metals (trace) shall not exceed 0.5 parts per million
k.Chemical contaminants: meet or exceed US EPA Class A
standard, 40 CFR 503.13, Tables 1 & 3 levels
l.Pathogens: meet or exceed US EPA Class A standard, 40 CFR
503.32(a) levels
PART 3 - EXECUTION
A.General
1.Refer to project specifications for excavation requirements.
B.Placement Method
1.BSM material shall be spread evenly in horizontal layers.
2.Thickness of loose material in each layer shall not exceed
9-inches.
3.Compaction of BSM material is not required.
