Technical data

The application rate is determined from baseline carbon:nitrogen:phosphorus present in the
untreated soil. Total organic carbon concentration in the untreated soil is used to establish
the baseline nutrient addition rates.
Nutrient are applied in dry granular form using a conventional spread caster. The relatively
small size of the treatment area favors the use of dry reagents which are manually applied
by operation personnel.
Nutrient levels will be measured in the biocell prior to each separate l,OOO-cubic yard batch
treatment and monthly during operation and maintenance. Composite soil samples will be
analyzed for the following parameters and frequency:

The Biocell is divided into six equal quadrants for nutrient monitoring purposes. Grab
samples should be collected by personnel approximately 6 inches from the surface from the
middle of each of the six quadrant locations and composited into three samples. The
samples should be numbered sequentiahy and sent with a chain-of-custody for off-site
analysis. The results are compared with the target nutrient ratios and adjusted as
necessary to maintain biological treatment efficiency and modify the operating plan as
needed. Nutrient monitoring will continue monthly until the batch reaches the soil
treatment standards listed below in Table 1.2.
