(a) Is not a hazardous waste as defined in RSA 147-A:2, VII;

(b) If derived from human waste, consistently meets the pathogen and vector attraction requirements specified in the application;

(c) Does not exceed the following concentrations, expressed as the total concentration on a dry weight basis:

(1) For total arsenic, 32 mg/kg;

(2) For total cadmium, 14 mg/kg;

(3) For total chromium, 1,000 mg/kg;

(4) For total copper, 1,500 mg/kg;

(5) For total lead, 300 mg/kg;

(6) For total mercury, 10 mg/kg;

(7) For total molybdenum, 35 mg/kg;

(8) For total nickel, 200 mg/kg;

(9) For total selenium, 28 mg/kg;

(10) For total zinc, 2,500 mg/kg;

(11) For polychlorinated biphenyls (PCB), 1.0 mg/kg; and

(12) For dibenzodioxins and dibenzofurans, 27 ng/kg TEQ for all congeners determined by EPA method 1613 using the 1989 toxic equivalency factors;

(d) Is of sufficiently consistent quality such that for the constituents in (c), above, the mean concentration for data submitted under Env-Wq 809.01(h) plus one standard deviation from the mean does not exceed the concentration specified in (c), above;

(e) Is not a threat to public health, safety, or the environment from other chemical contaminants when assessed according to risk methodologies described in the United States Environmental Protection Agency's (US EPA's) Soil Screening Guidance, EPA/540/R-96/018 dated April 1996, the American Society for Testing and Materials E-1739-95, Guide for Risk-Based Corrective Action Applied to Petroleum Release Sites dated November, 1995, or equivalent approved pursuant to Env-Wq 811;

(f) If not generated in New Hampshire, meets the chemical standards of the state of origin for the equivalent category of sludge;

(g) If class B biosolids or mixtures of sludge containing class B biosolids that are to be certified for reclamation use, the material contains enteric virus concentrations of less than one plaque-forming unit per 4 grams of solid on a dry weight basis; and

(h) If the sludge is to be certified as low metals, does not exceed the following concentrations, expressed as the total concentration on a dry weight basis:

(1) For total arsenic, 10 mg/kg;

(2) For total cadmium, 10 mg/kg;

(3) For total chromium, 160 mg/kg;

(4) For total copper, 1,000 mg/kg;

(5) For total lead, 270 mg/kg;

(6) For total mercury, 7 mg/kg;

(7) For total molybdenum, 18 mg/kg;

(8) For total nickel, 98 mg/kg;

(9) For total selenium, 18 mg/kg; and

(10) For total zinc, 1,780 mg/kg.
