    (a) Sewage sludge (other than domestic septage). (1) The frequency 

of monitoring for the pollutants in Tables 1 and 2 of Sec. 503.23; the

503.32(b)(2); and the vector attraction reduction requirements in Sec. 

503.33(b)(1) through (b)(4) and Sec. 503.33(b)(7) through (b)(8) for

    (2) After the sewage sludge has been monitored for two years at the 

frequency in Table 1 of this section, 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).

    (b) Domestic septage. If the vector attraction reduction 

requirements in Sec. 503.33(b)(12) are met when domestic septage is 

placed on an active sewage sludge unit, each container of domestic 

septage shall be monitored for compliance with those requirements.

    (c) Air. Air in structures within a surface disposal site and at the 

property line of the surface disposal site shall be monitored 

continuously for methane gas during the period that the surface disposal 

site contains an active sewage sludge unit on which the sewage sludge is 

covered and for three years after a sewage sludge unit closes when a 

final cover is placed on the sewage sludge.
