Part 503 appears to be the only regulation whose purpose does not include minimum standards to protect public
health and the environment. The Surface disposal requirements of 503 would come close but it would prevent the
use of sludge on farms and lawns.
Part 503 is a result of a court order that EPA could not issue pretreatment removal credits without a use and
disposal regulation in place. The only pollutants address are those for which removal credits could be issued.
According to the court, "EPA has consistently interpreted the Section 307(b) requirement that removal credits not
prevent the use or disposal of sludge to mean that whatever use or disposal the POTWs make of their sludge, they
must comply with all applicable federal, state, and local requirements, not just whatever guidelines EPA may have
explicitly promulgated under Section 405(d). See 43 Fed. Reg. 27749 (1978); 40 C.F.R.403.7(a)(3)(iv).
EPA failed in this case.
