    The following special monitoring and reporting requirements apply to

    (1) The first wastewater sample of each calender year has been 
analyzed and found to contain less than 0.07 mg/l cyanide.
    (2) The owner or operator of the aluminum forming plant certifies in 
writing to the POTW authority or permit issuing authority that cyanide 
is not and will not be used in the aluminum forming process.
    (b) As an alternative monitoring procedure for pretreatment, the 
POTW user may measure and limit oil and grease to the levels shown in 
pretreatment standards in lieu of measuring and regulating total toxic 
organics (TTO).
    (c) The ``monthly average'' regulatory values shall be the basis for 
the monthly average discharge limits 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.
