Sec. 468.03  Monitoring and reporting requirements.

    The following special monitoring requirements apply to all 
facilities controlled by this regulation.
    (a) The ``monthly average'' regulatory values shall be the basis for 
the monthly average discharge in direct discharge permits and for 
pretreatment standards. Compliance with the monthly discharge limit is 
required regardless of the number of samples analyzed and averaged.
    (b) As an alternate monitoring procedure for TTO, indirect 
dischargers may monitor for oil and grease and meet the alternate 
monitoring standards for oil and grease established for PSES and PSNS. 
Any indirect discharger meeting the alternate monitoring oil and grease 
standards shall be considered to meet the TTO standard.
