The producer of the biosolids is responsible for the quality of the product. It is the responsibility of the producer to meet or exceed all applicable Federal, State, and local laws, regulations, and ordinances. It is also the responsibility of the producer to treat its biosolids such that obnoxious odor problems do not result at the application site with the employment of best management field practices. Loudoun County reserves the right to review records of the producer to determine compliance with all applicable standards, particularly those concerning the following State and Federal regulations:
(a) Monitoring Regulated Parameters.
(1) Inorganic pollutants (metals)
(2) Pathogenic indicators
(3) Vector attraction characteristics (including odor potential).
(b) Record-keeping.
(1) Inorganic pollutants.
A. Metals
B. Other pollutants.
(2) Pathogenic indicators.
A. Fecal coliform counts
B. Aerobic digestion
C. Air drying
D. Anaerobic digestion
E. Composting
F. Lime stabilization (pH 12 for 2 hrs)
G. PSRP equivalent.
(3) Vector attraction reduction options (from Table 2-6, A Plain English Guide to the EPA Part 503 Biosolids Rule).
A. Reduce the mass of volatile solids by a minimum of thirty-eight percent.
B. Demonstrate vector attraction reduction with additional anaerobic digestion in a bench-scale unit.
C. Demonstrate vector attraction reduction with additional aerobic digestion in a bench-scale unit.
D. Meet a specific oxygen uptake rate for aerobically treated biosolids.
E. Use aerobic processes at greater than forty degrees Celsius (average temperatures forty-five degrees Celsius) for fourteen days or longer (e.g., during biosolids composting).
F. Add alkaline materials to raise the pH under specified conditions.
G. Reduce moisture content of biosolids that do not contain unstabilized solids from other than primary treatment to at least seventy-five percent solids.
H. Reduce moisture content of biosolids with unstabilized solids to at least ninety percent.
I. Inject biosolids beneath the soil surface within a specified time, depending upon the level of pathogen treatment.
J. Incorporate biosolids applied to or placed on the land surface within specified time periods after application to or placement on the land surface.
