    (2) After the sewage sludge has been monitored for two years at the 
frequency in Table 1 of Sec. 503.16, the permitting authority may reduce 
the frequency of monitoring for pollutant concentrations and for the 
pathogen density requirements in Sec. 503.32(a)(5)(ii) and (a)(5)(iii).

Sec. 503.33(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.
