----------------------------------------------------------------------------------------------------------------
\1\ Either the amount of bulk sewage sludge applied to the land or the amount of sewage sludge prepared for sale
or give-away in a bag or other container for application to the land (dry weight basis).

(2) After the sewage sludge has been monitored for two years at the frequency in Table 1 of ง503.16, the permitting authority may reduce the frequency of monitoring for pollutant concentrations and for the pathogen density requirements in ง503.32(a)(5)(ii) and (a)(5)(iii).

(b) Domestic septage. If either the pathogen requirements in ง503.32(c)(2) or the vector attraction reduction requirements in ง503.33(b)(12) are met when domestic septage is applied to agricultural land, forest, or a reclamation site, each container of domestic septage applied to the land shall be monitored for compliance with those requirements.
