Section 271.917 - Frequency of monitoring(a)Sewage sludge other than residential septage.(1) The frequency of monitoring for the pollutants listed in Table 1, Table 2 and Table 3 of § 271.914 (relating to pollutant limits); the pathogen density requirements in § 271.932(a) and (b)(2)-(4) (relating to pathogens); and the vector attraction reduction requirements in § 271.933(b)(1)-(8) (relating to vector attraction reduction) shall be the frequency in Table 1 of this section. TABLE 1-FREQUENCY OF MONITORING-LAND APPLICATION
| Amount of Sewage Sludge1 (Tons/Or Metric Tons Per 365 Day Period) | Frequency |
| Greater than zero but less than 319 (290) | Once per year |
| Equal to or greater than 319 (290) but less than 1,650 (1,500) | Once per quarter (4 times per year) |
| Equal to or greater than 1,650 (1,500) but less than 16,500 (15,000) | Once per 60 days (6 times per year) |
| Equal to or greater than 16,500 (15,000) | Once per month (12 times per year) |
1 Either the amount of sewage sludge applied to the land or the amount of sewage sludge received by a person who prepares sewage sludge that is sold, given away or otherwise distributed, in a bag or other container for application to the land (dry weight basis).
(2) After the sewage sludge has been monitored for 2 years at the frequency in Table 1, the Department may reduce the frequency of monitoring for pollutant concentrations and for the pathogen density requirements in § 271.932(a)(5)(ii) and (iii). However, the frequency of monitoring may not be less than once per year when sewage sludge is applied to the land.(b)Residential septage. If either the pathogen requirements in § 271.932(c) or the vector attraction reduction requirements in § 271.933(b)(11) are met when residential septage is applied to agricultural land, forest or a reclamation site, each container of residential septage applied to the land shall be monitored for compliance with those requirements.
