i.0 SYSTEM OPERATIONS
The Biocell located at Lot 203 is designed to treat only petroleum contaminated soil ;as
defined in N.C.G.S. 143-215.1.
Petroleum contaminated soil is loaded into the cell vii a
dozer or tracked loader, Prior to loading the soil a sample is taken from the soil to confirm
that the soil meets requirements to enter the cell and to get a baseline for nutrient addition.
The material is spread over the cell in a l-foot lift. Nutrients are applied in dry granular
form using a conventional spread caster at a rate based upon initial baseline nutrient
sampling. The nutrients are tilled into the material using a tractor with disc attachment.
The Biocell is then tilled as needed based upon the moisture content of the soil. After one
month, the material is sampled. %f the material is below the cleanup criteria, then the
material is loaded out and stored awaiting final disposition by the base.
If the material is
above the cleanup criteria, then the process continues until the cleanup criteria is attained.
Appendix B contains the as-built drawing depicting the layout of the biocell.
1.1
INCOMING MATERIAL ACCEPTANCE TESTING
Petroleum soils identified for treatment at this facility from MCB Camp Lejeune include: (1)
contaminated soils where the source of contamination was virgin petroleum products from
regulated USTs and which are not hazardous wastes under the North Carolina
Administrative Code; (2) contaminated soils where the source of the contamination is
neither virgin petroleum products from a regulated UST, nor a listed hazardous waste, nor
a characteristic hazardous waste in accordance with the TCLP test (40 CFR 261.24)
Soils which are characteristically hazardous for RCRA metals (Arsenic, Barium, Cadmium,
Lead, Mercury, Selenium, Silver, or Chromium) or volatile and semi-volatile organics cannot
be managed at this facility. Therefore, prior to acceptance and treatment of TPH
contaminated soils from MCB Camp Lejeune, incoming loads to the Lot 203 facility are
certified as nonhazardous based upon appropriate testing results in accordance with the
requirements of 15A NCAC 2H.0200. These certifications are the responsibility of the
generator of each incoming load.
1.2 NUTKIENT ADDITION
Soil fertility is managed through conventional fertilization techniques, using rela%ively
soluble commercial fertilizers. The soil biotreatment facility is designed to accommodate
both dry granular fertilizer or aqueous based nutrients.
The primary nutrients used include
diammonium phosphate and ammonium sulfate. The initial nutrient addition ratios should
be consistent with North Carolina regulations for dedicated facili%ies based on organic
carbon:ni%rogen:phosphorus of 60:1:.075.
