Sec. 430.35  New source performance standards (NSPS).

    Any new source subject to this subpart must achieve the following 
new source performance standards (NSPS), except that non-continuous 
dischargers shall not be subject to the maximum day and average of 30 
consecutive days effluent limitations for BOD5 and TSS, but shall be 
subject to annual average effluent limitations. Also, for non-continuous 
dischargers, concentration limitations (mg/l) shall apply, where 
provided. Concentration limitations will only apply to non-continuous 
dischargers. Only facilities where chlorophenolic-containing biocides 
are used shall be subject to pentachlorophenol and trichlorophenol 
limitations. Permittees not using chlorophenolic-containing biocides 
must certify to the permit-issuing authority that they are not using 
these biocides:
