B. An activity report shall be submitted (electronically or postmarked) to the department by the 15th of each month for land application activity that occurred in the previous calendar month, unless another date is specified in the permit in accordance with 9VAC25-32-80 I 4. The report shall indicate those sites where land application activities took place during the previous month. If no land application occurs under a permit during the calendar month, a report shall be submitted stating that no land application occurred.

C. Records shall be maintained documenting the required treatment and quality characteristics and the maximum allowable land application loading rates established for biosolids use. In addition, operational monitoring results shall verify that required sludge treatment has achieved the specified levels of pathogen control and vector attraction reductions (9VAC25-31-710 and 9VAC25-31-720). Adequate records of biosolids composition, treatment classification, and biosolids application rates and methods of application for each site shall be maintained by the generator and owner.

D. The generator and owner shall maintain the records for a minimum period of five years. Sites receiving frequent applications of biosolids that meet or exceed maximum cumulative constituent loadings and dedicated disposal sites should be properly referenced for future land transactions (Sludge Disposal Site Dedication Form).
